    The invention is concerned with a hydraulic shield-type support for supporting roofs in mines comprising a pair of base slides between which is located a channel-section guide beam supporting an hydraulic ram. At the rear end of the hydraulic ram a yoke is pivotally connected at a central part thereof to the rear end of the guide beam, the two outer portions of the yoke being pivotally connected to the rear end portions of the base slides. The front extendable end of the ram is connected to an elongate flat tongue which is longitudinally slidable in the guide beam underneath the hydraulic ram.

    专利说明:

    The invention relates to mobile lining devices and can be used in the extraction of coal in lavas equipped with mechanized lining.
    A device for moving a support section is known, comprising a shifting cylinder located between the skis of a section, which is connected at one end to the cross-bar of the connecting ski from the bottom, and the other through the crossbar from the side of the tab with a straining rod, the bottom end of which abuts the conveyor or guide beam fl.
    However, this device has a large DD1INU and a complex structure, since the traverses must compensate for the load that occurs when the sled moves on uneven soil, preventing the transfer of transverse forces to the hydraulic cylinder, and the location of the traverse from the bottom side contributes to an increase in their attacks on the obstacle.
    The closest to the present invention is a device for shifting a section of hydraulic shield support, including a double-acting displacement cylinder, movably mounted between two skis of a shield support shield connected by a traverse located on the side of the tab and made as an additional horizontal beam, can be rotated in a vertical plane, the outer tube of which is pivotally connected with the skis, and the inner tube with the moving rod, which is movably mounted in the direction of the skis, is located zhennoy mezedu ski, and is connected with the beam attached to the conveyor Q2.
    The disadvantage of such a device is the transfer of forces acting on one of the skis through the lever of the guide and the fence to the other ski and the crushing of the bottom-hole part of the latter into the soil.
    The aim of the invention is to increase the efficiency of the device by uniformly distributing the loads as the section is moved.
    This goal is achieved by the fact that in the device for shifting hydraulic shield support.
    including a moving cylinder, no double action, movably mounted between two skis of shield shield support, connected by a traverse, located on the side of the inlay and made as an additional horizontal beam, can be rotated in a vertical plane, the outer tube
    which is hingedly connected with lishami, and internally with a moving rod, which is movably mounted in a guide located between the skis and connected to the beam,
    attached to the conveyor, the yoke is connected with the ends of the skis, guides are made U-shaped, its inlet end is fixed on the middle part of the yokes by means of a vertical hinge, while the hydraulic slide is mounted on the shifting rod, and its outer tube is fixed on U shaped guide.
    Each ski can be equipped with a bearing, the body of which is fixed on the skid side of the ski, and connected to the crosspiece by means of a vertical axis and an associated roller, which can be rotated around its longitudinal axis in the bearing housing.
    In addition, in order to facilitate passage through the lining, moving the rod can be connected to the conveyor by means of a beam, made in the form of a bath in the transverse section.
    Figure 1 shows schematically the pre; The hooked device, a top view of J in Fig. 2, is a section A-A in Fig. 1; FIG. 3 shows a knotted joint of skis on the zavalny end; in fig. 4 - section BB in FIG. 3} in FIG. 3 - side view of the device.
    The device for moving the section includes a double-acting hydraulic cylinder 3 located between the skis 1 and 2 of the 1-kit section, which is housed in a box-shaped L-shaped guide 4, the bottom shelf of which is supported on the ground. Arcuate in cross section, the collar 5 connects the cylinder 3 with a guide 4
    using vertical bolts 6,
    inserted into the lugs of the guide 4 and the holes in the collar 5. The hydraulic cylinder is connected with the protrusion 7 of the shifting rod 8, which has a rectangular shape and is placed in the guide 4 under the hydraulic cylinder 3 with the possibility of longitudinal movement. The moving rod 8, by means of a beam 9, formed as a bath and attached to the stop 7, is connected with a bottom end conveyor (or with a guide beam) of the excavating machine to the bottom hole. On the side of the tab, the moving rod 8 is vertical by the hinge 11 connected to the middle part of the crosspiece 12, the ends of which are connected to the skis 1 and 2 by means of horizontal bolts 13, which can be rotated around the longitudinal axis in the bearing housings 14 located on the skid side of the skis 1 and 2, wherein the bolts 13 are hingedly connected to the crossmember 12 by means of vertical axes 15, which are mounted in the opal holes 16 formed at the ends of the crossbar 12, the crossbar 12 is made in the form of a horizontal beam. The collar 5 is mounted on the outer 17 tube of the hydraulic cylinder 3, and with the stop 7 it is connected by the inner tube 18.
    The device works as follows.
    When the working tube is fed, the inner tube 18 of the hydraulic cylinder 3 extends, while the moving rod 8 connected with it through the stop 7 moves out in the direction of the bottom. guide 4 and moves conveyor 10 through beam 9. Skis 1 and 2 are unraveled with hydraulic girders. Then, the securing section is pulled to the conveyor, which is held by adjacent unwrapped sections. For this purpose, the working fluid is fed into the rod cavity of the hydraulic cylinder 3, the moving rod 8 enters the guide 4 which is pulled by the hydraulic cylinder 3, and through the cross beams 12 moves the skis 1 and 2 to the bottom.
    The proposed device allows to ensure uniform loading of the ski section when shifting and to increase the efficiency of work. i-A
