Abstract

Usage: in devices for moving tram trolleys on a parallel rail track when repairing trams. SUMMARY OF THE INVENTION: the device comprises a portal moving along rails and having retractable grips, each of which is made with a supporting surface inclined in longitudinal and transverse sections and with a groove for interacting respectively with the rolling surface of the wheel of the tram carriage and with its flange. 3 C.p. f-ly, 3 ill.

Description

WITH

The invention relates to the construction and repair of trams, in particular to the movement of tram carts from one rail track to another parallel to it.

A lifting car is known for vehicles with a hand pump, with a telescopic horizontal carrier, which can be mounted on the wheel of the machine on the machine side, the telescopic carrier having two running axles spaced apart from each other with wheels, the wheels of which are made rotary, and two lying between them in the main direction relative to the running axes of the lifting arms, which are due to the reduction of the telescopic support by the axis of the wheels of the vehicle, and Telescopic ositel formed withdrawable unit composed of the piston and cylinder which imparts one axle and the lifting arm, lifting levers bear

on itself rotary, coming into contact with the working plane of the vehicle, plastic rollers, and the ends of the levers are bent so as to partially capture the wheel of the vehicle.

Known is an automatic device for reloading various cargoes, comprising a traverse, movable in a vertical direction, under which a rotary plate is mounted with a portal suspended on it, which moves along rails mounted on the plate, and contains rods carrying sliding rods at the ends equipped with movable transverse fingers to capture cargo.

This automatic device has a complex structure and cannot capture tram carts.

The purpose of the invention is to simplify the design and expand technological capabilities.

This goal is achieved in that a device for moving objects, mainly tram carriages, comprising a rail-moving portal with retractable grips, each of which is made with a supporting surface having a slope in the longitudinal and transverse sections, and with a chute for interacting respectively with the top - Hoffbid Katays wheels of the tram car and with its flange, the portal drive is made. 56 chain sprockets on drive wheels and a tensioning device, the portal is formed by at least two arched racks connected by transverse racks, interconnected by transverse beams and sheets forming compartments with the inner surface of the portal along its contour for placement of working equipment in it, and the lower surfaces the grippers are made with limiters of their movement in the form of stepped protrusions.

In FIG. 1 shows a device, a General view; figure 2 - view A; Fig. 3 is a view of B; figure 4 - view B.

The device consists of a portal 1 formed by transverse struts 2 connected by transverse beams 3 and sheets 4, forming compartments a, in which accumulator batteries 5 are placed; hydraulic equipment 6 and electrical equipment 7, and longitudinal beams 8 with guides 9 and gripping and lifting elements 10 having inclined ends B with grooves C, with stiffeners and contact surfaces e of horizontal planes W made at an angle to the horizontal along the profile of the gripping wheels 11, movement drives 12, chain transmission 13, with a tension device 14 mounted on drive wheels 15, with sprockets 16 and non-drive wheels 17 moving along the rails 18, power cylinders 19, pivotally mounted with Altsov 20 with guides 9 and fingers 21 with gripping and lifting elements 10. Guides 9 are fastened with longitudinal beams 3 bolted, connections 22. For the possibility of gripping the wheels 11 of the grips 24 in the lower part, the wedge ends of the gripping and lifting elements are made with ledges AND.

The device operates as follows.

In a static state, all mechanisms are in an awkward position. The gripping and lifting elements 10 are in an advanced state, equipment,

located in compartments, closed by covers 23.

By turning on the drive 12, the device moves to the gripping position of the carriage 24. After stopping

-the power cylinders 19 are turned on and the gripping and lifting elements 10 begin to be pulled out, which enter the plane Zh in contact with the wheels 11 of the carriage 24 and begin to raise the wheels 11 of the carriage 24 with their wedge surface b. After lifting, the device 12 moves the device to the corresponding position, after include power cylinders 19, which, by sliding the gripping and lifting elements 10, lower and install the trolley 24 on the rails 25. When passing the break point of the rail track 26, one wheel of each pair of wheels is always in contact teasing with rails.

When moving the trolley for 24 s

large wear of the rolling plane of the wheels

11 raising and lowering are carried out for
