Description

The invention relates to stationary lifts equipped with platforms in the form of platforms, cradles, etc., with shoes connecting said platforms with guide posts. Vertical movement of the platforms along the uprights on their sides, which slide the shoes, is carried out under the action of counterweight cargoes connected to the platforms using flexible connections (ropes, chains, etc.) that surround the rollers placed on fixed supports. 3 bolts, etc. are used to secure platforms to the desired height. safety devices passed through racks and shoes. In the proposed car repair device, rails or beams are used as guide posts, in which the sole edge is used to guide the platform shoes, the rail head or the second beam flange — to guide the movements of the counterweight — and a neck with horizontal pins like climbing ladder on the platform.

In the schematic drawing of FIG. Figures 1 and 2 depict a view of the device in two projections.

Usually, in repairing railroad body wagons, various kinds of portable racks, ladders, benches, etc. are used, which is unsafe for workers, and, moreover, it clutters the workshop, preventing the use of intrashop vehicles for transporting various parts, etc. p. The proposed stationary carriages for repairing cars designed to eliminate these drawbacks are located along the tracks on which the cars to be repaired are introduced and do not interfere with transportation materials and products in the shop. Along the tracks on which the repaired cars are installed, there are a number of vertical posts in the form of rails or I-beams 7 and 8. Between each pair of said rails or beams a platform 1 is placed, to the ends of which are attached shoes 9, 10, axle: tyvak) employee as the guide edge of the rail foot or the polk beam.

Platform 1 is suspended at its ends by ropes or chains x 2 and 3, which go around rollers 4, 5. The axles of the rollers are fixed in solid, floor-mounted, rail or any other posts. Cables 2, 3 Converge together on roller 4 and both are fixed to the counterbalance weight equalizing the platform. B.

In the proposed device, the platform will always be raised or lowered.

parallel to itself, regardless of where the force is applied — whether on the platform itself, in different places or directly to the load.

The rail heads 7.8 or second flanges of the beams are used to guide the load 6. To hold the platform at the required height in the base of the rails or the shelf of the beams, a number of holes are drilled into which iron tabs or bolts are inserted, also passing through the shoes 9 and 10. For climbing a high-raised scaffold, a rail neck is used in which, along the entire height of the latter, the required number of iron pins 11-12 is inserted. To prevent worker from falling, one side of the platform must be protected by a barrier.

To service the end sides of the cars, there is a spare board, which with its ends is placed on platforms 1. After the need for it is removed, the board is removed and laid either on the platform or on the floor of the workshop parallel to the track.

subject matter of the invention.

A stationary lifting device for repairing cars with a platform equipped with shoes sliding along the platform, columns located on the sides of the platform, suspended on chains, envelopes, blocks fixed on fixed supports, to a counterweight cargo placed on one side of the platform and fixed on the required the height by means of bolt bookmarks passed through racks and shoes, characterized in that racks 7 and S or beams are used as racks, in which the edge of the sole or shelf facing the platform serves as is yushey for shoes 9 and the platform 10, second or 'head shelf intended for guiding movement of the counterweight 6, and provided with the entire height of the horizontal pins cervix used as a ladder for climbing onto a raised platform.
