Description

The invention relates to a traveling technique, namely, devices for testing rail grabs continuous action.

Known track lifter, containing the undercarriage, farm, mounted on the undercarriage, the lifting mechanism of the track grid, which includes rail grabs and mounted on the farm, and a winch [1].

The disadvantage of the track lifter is that due to the preparation and test paths and the impossibility of reversing work, the test time increases.

The aim of the invention is the provision of tests of rail grabs.

To achieve this goal, the proposed tracker is equipped with a device for fixing the track grid in the raised position and pressure cylinders fixed on the farm by pressing the track grid; through the rope around the block, elastically

mounted on a stationary support and placed on the side of the track ramp opposite to the winch. In addition, the device for fixing the track grid in the raised position contains a plate and a roller conveyor mounted on the plate with the help of power cylinders.

FIG. 1 shows a track elevator, a general view; in fig. 2 - the same, top view; in fig. 3 - device for fixing the track grid.

The elevator includes a truss 1 supported on railroad trolleys 2, a device 3 for fixing the track grid in the hung position in the area of the rear truck, a loading mechanism 4 for the track grid. The device for fixing the track grid in the posted position with the farm is connected by means of flexible rods 5. Flexible rods 5 on farm 1 are fixed in frame 6 moving in rails 7. Movement of frame 6 relative to rails 7 is carried out using hydro cylinders 8.

The lifter is equipped with a reversible winch 9 with electric drive and an anchor 10, on which the fixed block 11 is mounted.

The device for fixing the track lattice in an open position consists of an upper frame 14 equipped with roller conveyors 15. The lower part of the device is made in the form of a plate 16 equipped with inclined planes 17. The upper part of the device is raised and lowered relative to the lower along inclined planes by means of a hydraulic cylinder 18.

The track lifter works as follows.

In the initial position, the truss 1, equipped with rail grippers 13, is installed near the armature 10 or winch 9, the track grid 19 is hung to a predetermined height, and the conveyors 15 of the device for fixing the track grid in the hung position are installed to a predetermined height by means of a hydraulic cylinder 18.

Mechanism 4 is brought into the working position (in the forward span in the direction of travel between the support carriage and rail claws) for prigrue of the track grid, i.e. pinch rollers are lowered onto rails.

After setting up the bench to the parameters specified in the experiment, the process of continuous lifting begins: the winch 9 is turned on (right or left depending on the direction of lifting) and the truss 1, equipped with rail grippers 13, starts moving. Simultaneously with the farm 1, the track 20 moves along the path 20 laid on the subgrade and the device 3 for fixing the track grid in the hung position.

At the approach of a truss 1 with rail grippers 13 and a device 3 for fixing the hung track grid to the extreme position, they change the direction of rotation of the drum of the winch 9, and the truss 1 with rail grips

13 starts moving in the opposite direction. At the same time at the initial moment, farm I with rail grippers 13 moves independently of the device for fixing the posted track grid. This device begins to move after the rear (former front) vehicle is installed in the direction of travel. At the same time, the presence of flexible kicks 5 does not require any additional adjustment of the stand when the lifting direction is changed.

The use of track-lifter can significantly reduce labor costs during testing and testing time.

Claims (2)

Claim 1 Lift raiser, containing running gear 20, a truss attached to the undercarriages, a track grate lifting mechanism including rail clamps and fixed on the truss, and a winch, that is, The purpose of providing 25 tests of rail grippers is that it is equipped with a device for fixing the track grid in the raised position and pressure cylinders fixed on the farm by pressing the track grid, moreover, said device 30 for fixing the track grid is connected to the farm with flexible rods, and the winch is placed with hydrochloric hand track-lifts and connected with the farm by the rope, the enveloping unit, elastically mounted on stationary support 35 and hydrochloric disposed on the opposite side from the winch track-lifts. 2. Track lifter on π. I, who are talking about the fact that the device for fixing the track grid in the raised position so40 holds the plate and the roller conveyor fixed on the plate with the help of power cylinders.
