Abstract

Lifting device is a stationary compact block module designed for automatic installation on rails when moving railway equipment is approaching, comprising a pump and control unit, a pipeline, lifting and moving mechanisms, characterized in that the housing of the lifting mechanism is rigidly connected to the supporting table of the roller carriage, and the rod - with the frame of the carriage, the support-rolling beam of the box section has a longitudinal slot in the upper part of the body in full length, and the width of the slot is equal to the diameter of the body of the lifting mechanism ma-knurled end of the supporting beam rigidly closed plate, the center of which is rigidly fixed body moving mechanism, the rod of which is connected to a trolley located within thumb support-beams.

Description

: LIFTING ycTPoIciBd

The utility model relates to railway transport and relates to the construction of restorative means of railways.

A device for setting on the way rolling stock off the rails and.with. R 572194 B6I K 5/04 72, containing rolling beams located across the path, lifting and moving mechanisms, a pump-control unit.

The device operates as follows. Under the front part of the car, descended from the rails, two rolling beams are laid on the rails and lining. On each roll-up beam there are two roller trolleys with lifting and moving mechanisms connected to the pump-control unit. Raised by four lifting mechanisms, the carriage is shifted by the moving mechanism towards the installation and lowered onto the rails. The device is delivered to the meeting point by a repair train. Installation and dismantling is performed manually. The time spent on the delivery of the device, its installation and dismantling is proportional to the idle timeline.

The purpose of the utility model is to reduce downtime by eliminating the disadvantages of the prototype.

This goal is achieved by the fact that the proposed device, repeating all the main features of the prototype / lifting and moving / differs from it by the simplicity of the structural solution at the level of the block module allows you to solve the same problems without manual labor and in a shorter time.

The hoisting system contains: a pump and control unit, a pipeline, hoisting and moving mechanisms, a roller trolley and a support rolling beam. The hoisting mechanism is rigidly connected to the carriage by a rod. The design of the rolling beam differs from the prototype in that having the same box-shaped cross-sectional shape, the movement of the trolley is not on the upper, its plane, but on the lower, inner. The upper part of the box sends a longitudinal cutout according to the diameter of the lifting mechanism, the sleeve of which is rigidly fixed to the table of the cart. At the end of the knurled beam, a plate is rigidly placed on which the movement mechanism is rigidly fixed, the rod of which is connected to the trolley ensuring its reliable reciprocating movement inside the knurled beam, which, in comparison with the design of the knurled beam of the prototype, eliminates the need for manual rearrangement of the shifting mechanisms

cent, after every 40 cm of movement and correction of the direction of the rolling beam along the tangent movement of the car, the center of the radius of which is located on the rotary axis of the rear undercarriage. The width of the support table of the trolley is greater than the upper slot of the rolling beam, which ensures reliable fzsatsiya carts inside the rolling beam and is the main element in connecting the lifting and moving mechanisms in one compact unit.

The list of figures of the graphic image. In FIG. I depicts the WDC on top of a snow removal plow coming off the rails with the designation of the locations of the lifting devices. In FIG. 2 side view of the plow SDN-M with the designation of the installation sites of lifting devices. In FIG. 3 is a side view of the lifting device in section along AA, FIG. I. In FIG. 4, section BB is shown; FIG. 3.

The operation of the lifting device is illustrated by an example of its use on a plow of a snow plow. The device is rigidly attached to the middle console of the frame I, Fig. 1.3 between the carriage II / Fig. 1/ and the frontal shield 10 / Fig. 1/ on both sides of the plow 12 / Fig. 2/ and connected by a pipe 2 / Fig. 1/ with a pump and control unit 3 / Fig. 1 / is located in the cab of the car. The assistant to the driver installs 4 / fig.Z/ under the support knurled beam 5 / fig.Z/ wooden inventory lining and directs the process of liquidation of the gathering. The starting position of the lifting device. The rod 6 of the lifting mechanism 6 / Fig. 3/ is retracted, and the rod 7 of the moving mechanism 7 / Fig. 3 / is extended in the opposite direction of movement. At the signal of the assistant, the driver brings the drive to the working position and the control unit directs the working fluid through the pipeline 2 / Fig. I / in the piston part of the approach mechanism b / Fig.Z/. Having lifted the plow with a pair of wheels, the working fluid is sent to the rod cavity of the moving mechanism, while the roller trolley 9 / Fig. 1/ with the car moves to the distance of the rod length T. Then, the working fluid is sent to the rod cavity of the lifting mechanism b until the wheels are running on the ground, the working fluid switches to the piston cavity of the moving mechanism 7, bringing the installation to its original position.

Duty cycles are repeated until the wheeled trolley 8 / Fig. I / does not click over the rail heads. In the transport position, the elevator rod is retracted into the cylinder body.
