Excavator safety device
专利摘要:
A safety device for passenger transporter systems for the prevention of the wedging in of foreign bodies, with a switching element, the latter serving to stop the transporter system, the switching element to be actuated from within the stationary part of the intake by means of horizontally moveable comb segments and/or a rotatably arranged carrier plate, the switching element comprises a switch which is operatively actuated via an angle lever, the latter being moved by means of a switch rod. One of the legs of the angle lever is connected with a push rod which can actuate the switch, the push rod being biased by means of a compression spring. The passenger transporter system upon displacement of at least one comb segment and/or upon lifting of the carrier plate as a consequence of pivoting about a pivot point is stopped by actuation of the switch by means of pivoting of the angle lever. 公开号:SU843727A3 申请号:SU792771226 申请日:1979-06-01 公开日:1981-06-30 发明作者:Шеневайс Клаус 申请人:О Унд К.Оренштайн Унд Коппель Аг(Фирма); IPC主号:
专利说明:
This invention relates to transportation and concerns the construction of safety devices for an escalator. A safety device for an escalator is known, which contains a support plate carrying comb segments connected to a switching device that interacts with a switch and a transverse rod 1. The disadvantage of this device is low operational reliability. The purpose of the invention is to increase reliability in operation. The goal is achieved by the fact that the device is equipped with a Teflon film, and the switching device is made in the form of an angular lever, equipped with a pusher, taken & and operating with a switch, with each groove made of grooves and equipped with a spherical head screw and dishwasher a spring placed in the said groove, by means of which the comb segment is attached to the base plate, and a Teflon film is installed between the comb segment and the base plate in the place of their fixation. FIG. 1 shows a device, a cross section through a comb segment located on a movable support plate (a view of a drive device with a switch and a view of a crank lever with stops); in fig. 2 - the same, VIA from above; in fig. 3 - cross-section through the plate support. The installation (not shown) installed in the stationary part of the vehicle transporting people through the support neck 1 in the bearings on the legs 2 of the support plate 3 across the entire width of the step, for example an escalator, is arranged next to each other along the ladder next to each other. The fastening is made by means of spherical head screws 5, which are inserted into the grooves 6 of the comb segment 4. By means of the disc springs 7 located between the screw head 5 and the groove 6, aka pressing force which causes the abutment comb segment 4 to the base plate 3. Furthermore, between the comb .se17mentom 4 and the base plate 3 is made of teflon film 8, to achieve independent pressing force constant friction coefficient. On the end of the ridge segment 4 projecting beyond the base plate, there are comb spines 9 entering the grooves 10 of the step 11. On both sides of the movable comb segments the bend levers 12 can be rotated. These levers, at their 3 ends entering the notches 13 of the base plate, are provided with a strike bar 14 along the entire length of the step. At the cranks levers 12 there is a pusher 15 mounted on bearings in adjustable bearing bushings 16 and providing an anti-squeeze compression spring 17 and an adjustable cup spring 18 The attached fit of the switching rod 14 to the base 19 of the comb segment 4. A tip 20 is located at the end of the pusher 15, which leads to a switch 22 fixed to the holder 21. 3 Ity shoulders 23 bear against the fixed stops 24 and the pusher 15 is actuated as described above. The device works as follows. If in the grooves of step 11 there is any object that, when running steps 11 (escalator), abuts spikes 9, then the comb segment 4, which is fixed to the base plate 3, is displaced. With its base 19, the comb segment 4 displaces the connecting rod 14 in the direction of movement (horizontally) so that the crank levers rotate at the pivot points, displace the pushers 15, turn the switch 22 through tip 20, and consequently interrupt the escalator control circuit. and instantly stop the endless ribbon. When elevating the base plate 3 (vertically), the shoulders 23 are held on the stops 24 and the inclusion occurs as described above.
