    equipped with interacting with retaining reversing element, made in the form of a base mounted on the supply pipe, can be rotated, while the base is made with a slot with three branches, two of which are located at the angles to the third, on the eccentric the protrusion is a slot,, and the retaining element has a second section located from the side of the pipes symmetrically to the first section, it has a section about the axis of the retaining element,
    . The device can be equipped with a means for creating resistance to the movement of the supply pipe relative to the guide pipe, made in the form of a pressure spring fixed on the delivery pipe, interacting with annular grooves made on the outer surface of the guide pipe, as well as a ring of elastic material located in an annular groove made inside the supply pipe, wherein the width of the groove is greater than the width of the ring,
    In addition, at least the front end of the guide tube may be provided with a friction gasket located on the inner surface of the tube.
    At the end of the guide pipe from the supply side, a shoulder can be made, which is a front stopper for the supply pipe and serves as a gripping part for one of the working hands.
    An additional opening may be made in the wall of the guide tube for inserting one or more cables into the guide tube to simultaneously feed the lead wire and cable from the outlet of the guide tube,
    In this case, the device may contain a secondary pipe, one end of which is connected to an additional opening of the guide pipe and the other is located in the shoulder.
    FIG. 1 shows the device in the first working phase, side view; Fig, 2 is a side view, in the second working phase; in FIG. 3, the same in the third working phase; in FIG. 4, the same in the fourth working phase; in FIG. 5 a holding member; at the firm, 6 — switching the retaining element to the second operating position in FIG. 7 is a top view with a partial, section of the front of the device; FIG. 8 is a cross-section of FIG. FIG. 9 - device when pulling ropes; in fig. 10 is a device with two locking elements, side view; in fig. 11 - locking elements of the rear part of the device in the first working position; Fig. 12 is a sectional view of the retaining element on which the locking elements are in the second operating position.
    The device contains a fig. 1-5) two tubes 1,2, which are telescopically displaced relative to each other (respectively, supply and guide tubes). Inside the supply pipe. A guide pipe 2 is installed, the feed pipe comprises a flat end portion 3. The leading wire 4 passes through both pipes, the front end of this wire being in this case a clip that hooks or secures the front end of the pullable cable. Preferably, the lead wire 4 is made of a plastic element with a circular cross section of a diameter of 1-5 mm, the length of which corresponds to its purpose (5-25 m
    In addition to the lead wire with a circular cross section, a wire with a different cross sectional shape, such as a flat, oval or rectangular shape, can also be applied.
    The retaining element 5 is articulated with the supply pipe 1 and consists of a locking element b with two working sections 7 and 8. The locking element b is installed and can be rotated on the shaft or axial pin 9, which is supported by two opposite walls on the flat end section 3 of the supply pipe. The meshes 7 and 8 of the yogut interact with the support 10, which in this case is the inner wall of the supply pipe. Between the meshing sections 7 and 8 there is a linear section 11 which allows the leading wire 4 to freely pass between the locking element and the support when the locking element is in a position perpendicular to the support. Sections 7 and 8 are mainly composed of teeth or knurling and have a curved profile.
    The locking element 6 is pivotally connected by means of a pin 12 with a shoulder 13, which protrudes sloping back and down from the sleeve 14 (see, fig. 1 and figure 2), and the sleeve can move back and forth a certain distance along the flow pipe 1 , On the sleeve 14, a handle 15 is fastened, which is made mainly of rubber. The movement of the sleeve and the handle forward along the supply pipe 1 is limited by the lead wire 4, which is touched by the locking element 6. Thus, when the handle 15 is moved forward, the portion 7 of the locking element rotates to the lead wire, gradually increasing pressure on it until such time as promotion
    knobs forward becomes impossible. On the supply pipe 1 a cartridge or ring 16 is fastened, which is made of plastic or hard rubber. This ring 16 serves to facilitate, if necessary, retain the locking element in a position in which the lead wire is locked by engaging with a similar annular portion on the handle. Practically, this is done by pressing the operator’s fingers of the annular area on the handle in the direction of the ring 16. The locking element 6 shown in FIG. 5 is in the position of the first gripper when the handle 15 is moved to the operating position shown in FIG. 1 (moves in the direction of the ring 16) The locking element shown in FIG. 2 is in the neutral position when the handle 15 is moved to the operating position shown in FIG. 2 (offset to HeKOTjopoe distance from ring 16).
    A reversing element consisting of a board 17 with a retaining flange 18 serves to transfer the locking sludge, 6 from one working position to another. The card is rotated on a pin 19 fixed on the end section 3 of the supply pipe. The slot 20 on the plate 17 of the reversing device includes a protrusion associated with the locking element 6, which is the driving pin 12. The slot 20 has three branches (portions) 21-23, of which the first two protrude at certain angles from the intermediate branch 23 connecting the branches 21 and 22. The position of the intermediate branch 23 is connected with an arc line having a radius equal to the distance between the driving pin 12 and the card pin 19 when the leading pin is in the neutral position of the locking element. When the drive pin enters the slot 21 of the slot, the board 17 and, accordingly, the locking member are moved to feed the wire 4 forward (as indicated by arrow 24). When the lead pin .12 enters branch 22, board 17 (and, of course, locking element 6) is thrown to feed wire 4 back (as shown by arrow 25)
    A pressure spring 26 is installed on the supply pipe 1, having the form of a flat spring, which enters the transverse notch grooves 27 on the enveloping surface of the drive pipe 2 with a light contact clamp. The purpose of these spring clamps between the supply and guide tubes is to create resistance to the movement of the sleeve 14 relative to the delivery pipe, thereby ensuring that the handle 15 and the sleeve 14 can be installed in the correct working position before
    the beginning of the movement of the feed pipe relative to the guide. In addition to the spring and the recesses interacting with it, you can use, for example, a friction connection between the feed and drive pipes. The guide tube 2 has a shoulder 28, which is used as a front stopper for the feed pipe 1, as well as a gripping section for one of the operator’s hands (for people with a stronger right hand, the left arm covers the shoulder 28, while the right arm Holds the handle 16). The flange 28 has a predominantly annular profile. The guide tube 2 has a rounded or chamfered front end 29, which is necessary to ensure at least a weak friction between the guide tube and the lead wire passing through it. This prevents unintentional movement of the lead. the wires during the reverse movement of the supply pipe after it moves in the direction of flow. This friction increase action can be further enhanced by inserting, at least in the front end of the guide tube, a gasket 30, which increases friction and is installed on the inner surface of the tube. The liner 30 may be made of glass filled fiber, textile or similar material.
    In order to facilitate the insertion 5 of the lead wire 4 into the lead tube 2 and through it, the back lead entry of the tube can be formed with a conical surface 31 at the inlet.
    FIG. 7 and B, pipe 33, through which 0 a cable 32 passes, is connected to a side opening 34 in the front end of the guide pipe, said tube protruding from the opening of the shoulder 28 on the guide pipe, and said j is penetrated by such a pipe
    in such a way that it opens on the back of the collar where a cutting device 35 is installed to cut the cable 32. The cable 32 can be wound on a reel. (not shown), has
    for example, under the guide tube. Similarly, it is also possible to store the lead wire 4 on a coil connected to the feed pipe. You can imagine the promotion
    5 of the cable directly through the opening 34, it is possible to connect the cable directly to the lead wire clip 36 without advancing the cable through the passage in the leading pipe.
    O The device works in the following way.
    Suppose that the lead wire 4 is to be fed into a passage or channel into which the cable must be advanced.
    5 In FIG. 1 shows the device when
    the year-old pipe 1 is pushed forward as far as it is possible towards the shoulder 28,
    and the handle 15, as well as the sleeve 14, is pushed forward to the ring 16. In this position, the locking element 6 is in the gripping state, ensuring
    the connection between the lead wire 4 and the feed pipe 1. In order to advance the lead wires 4 forward one step, the feed pipe 1 must be removed. From the drill 28, As shown in FIG. 2, this.
    is carried out by moving the handle 15 in the opposite direction from the ring 16, whereby the handle 15 through the sleeve 14, the shoulder 13 and the leading pin 12 rotates the locking element 6 to the neutral position at which the connection of the locking element with the leading wire is broken. the knobs 15 back from the shoulder 28, the supply pipe 1 will occupy the position shown in FIG. This movement of the supply pipe is accompanied by stopping the movement of the sleeve 14 relative to the supply pipe, which is carried out by a pin 12, which has moved to the end of the first branch 21 of the slot (the board 17 serves as a stop stopping the movement of the sleeve 14 relative to the delivery pipe). The movement of the feed pipe 1 from the shoulder 28 is carried out without moving the lead wire. When the supply-pipe reaches the end position (as determined by the operator), the handle 15 moves in the opposite direction, the locking element 6 is moved to the gripping position, as shown in Fig. 4, in which the lead wire 4 is held relative to the guide tube. With further movement, the knobs in the direction of the shoulder 28 of the supply pipe 1 follow it, a part of the lead wire corresponding to the amount of movement made, is fed from the hole in the guide pipe 2, as shown in FIG. 4. It should be noted that the spring 26 always ensures the correct working position of the handle 15 before the relative movement between the supply and guide pipes begins.
    FIG. 6 shows how the board 17 is transferred in order to ensure the operation of the locking element 6 during its second operating cycle. In this case, the board turns upward around the pin 19 so that the drive pin 12 moves to the second slot branch 22. In this position, pulling the handle 15 away from the shoulder 28 means that the locking element will capture the lead wire 4, providing
    this way the lead wire can follow the supply pipe in the direction opposite to the flange 28. As soon as the handle starts moving forward with respect to the supply pipe, the locking element 6 will return; to the neutral position, thereby ensuring the free movement of the leading wire during the - movement of the supply pipe towards the shoulder 28.
    FIG. 9 shows the advancement of the cable 32 through the channel 37 from the box 38 (located, for example, in a room wall in a room) to an outlet 39 (in another room of this room). Channel 37 can be arbitrarily bent. The cable 32 must have a loop 40 that clings to the front terminal 36 on the leading wire 4. The lead wire is fed from the box 38 to the outlet 39, where the cable automatically disengages the lead wire (the leading wire is tilted in the opposite direction as shown in the drawing, with the clamp being reversed and the loop is released). This means that the cable is conducted through the channel simultaneously with the lead wire and that the lead wire can be returned to the box 38 without the need for an operator to move from one room to another to release the cable. Thus, the operator can move the cable from one place through the channel to the desired location. Practically, the lead wire can be advanced and, accordingly, returned with a speed reaching several 1X meters per minute.
    FIG. 10-12, the reversing element comprises a sleeve 41, which can be rotated to one and the other side with respect to the supply tube 1. The opposing locking elements 42 are connected to this reversing element, which are adapted to grip and hold the lead wire 4 between them. Like the locking device 6 described earlier, each of these locking elements has a linear section 11 and two working sections of the gripper 7 and 8, which are located on each side of this section. Similarly, the locking elements can be rotated around the pin 9, with the help of the pins 12 they are connected by the shoulders 13 so that they can be turned, the shoulders protrude backwards from the handle 15.

    Claims (7)
    [1]
    As shown in FIG. 12, the coupling 41 is rotatably mounted beyond the rod-like part 43, which is rigidly attached to the outside of the feed pipe 1, for example, by means of a screw connection. 5 In the rod-shaped part 43 there is a central slot 44 in which the locking elements b are placed, as well as a pin 9 mounted between two opposite walls of the rod-like part. The rod on the part has a protruding part with a thread 45 on which the locking nut 46 is screwed. Between the locking nut and the rod-like part 43 there is a flange protruding across the rivers of the coupling 41. With it, the coupling is fixed on the rod-like part. On the clutch. there is a knurled area 47 which serves to facilitate the holding of the sleeve as it rotates. On the coupling 41, two grooves 4 are cut, each of these grooves has three branches 49 (see Fig. 11), running parallel to the longitudinal direction of the leading wire and serving for leading the forward wire, branch 5 (see Fig. 10) which also runs parallel to the lead wire and serves to feed the lead wire in the opposite direction, and a transverse branch (fig. 11) connecting the branches 49 and 50 between them. When the mud 41 switches to the position shown in fig. 10 and 12, where the locking elements 6 are connected with the branches 49 of the grooves 48, it is obvious that the lead wire 4 can be fed forward, indicated by the arrow 51 in FIG. 10 Switching the feed direction is accomplished by simply turning the clutch so that the locking elements fit into the second branches 50 of the slots 48, as indicated by the arrow 52 in FIG. 11. It should be noted that the protrusion in the form of a leading pin 12 entering into the opening 20 (Fig. 1-5) corresponds to an elongated section 53 of the locking element b protruding from regions 7, 8 and 11 (Fig. 10-12). In order for the coupling 41 to be held in the desired position, a ball 54 pressed by a spring can be used (the dashed lines in FIG. 12, the ball entering either of the two seats 55 cut through the flange 56, the positions of which are determined by switching the switching positions. The variant shown in Fig. 10 has been improved further with respect to the variants shown in Figs. 1-5 in the part of the device for ensuring that the liver has more resistance to movement of the delivery tube relative to the lead pipe than resistance to movement the handle 15 with respect to the delivery tube, which has a different design. Thus, in this case, the guide tube 2 has a completely smooth outer surface, while the supply tube 1 has in its front part a sleeve 57 in which an annular groove 58 is made. A seamless elastic ring 59, which may be made of rubber, is inserted into the groove 58, said ring having a smaller width than groove 58. As long as the ring is somewhere between the two ends of the groove, it will create a slight locking action However, as soon as the ring approaches one or the other of the two ends of the groove, the locking action stops, and the supply pipe can move relative to the guide with relatively little effort. Claim 1. A device for advancing a long flexible wire through hollow aisles containing two telescopically interconnected pipes - a guide and a feed connected to a retaining element designed to grip a flexible wire and made in the form of an eccentric with a working section located on the opposite side pipes, characterized in that, in order to expand its functionality, it is provided with a reversing element interacting with a retaining member, made in the form of mounted on the supply pipe can be rotated, while the base has a slot with three branches, two of which are angled to the third, on the eccentric there is a protrusion entering the slot, and the retaining element has a second, working section located from the side of the pipe is symmetrical to the first working section relative to the axis of the holding element.
