Description

The invention relates to transport equipment, and in particular to devices for fixing transported equipment on railway platforms.

From the current level of technology, mounts are known: by extensions; wooden parts: persistent and side bars, inserts, linings, gaskets, spacers (conventional devices, the priority of the invention of which is associated with the beginning of mass transportation of goods on Russian railways at the end of the 19th century); standard reusable fasteners - a set of universal multi-turn fasteners (RF Patent No. 2399518, publ. 09/20/2010; RF Patent No. 108372, publ. 09/20/2011).

The disadvantages of fixing the equipment with stretch marks are: the need for a sufficiently large time; the use of great physical strength;

one-time use of wire in stretch marks.

The disadvantages of fixing the equipment with wooden parts (thrust and side bars, liners, linings, gaskets, spacers): the manufacture of material only from healthy wood; in fasteners made of hard rock, it is necessary to pre-drill holes for nails, which affects a significant increase in time; the use of great physical strength; unreliability of safety during prolonged use.

The disadvantages of fastening the equipment with standard reusable fasteners (a set of universal multi-turn fasteners - UMK): complex manufacturing technology and the use of non-standard parts in the manufacture of the kit; the use of several kit accessories to fix one wheel; the need for a sufficiently large time for fixing equipment; unreliability of safety during prolonged use.

The closest technical solution to the claimed adopted as a prototype is a set of universal multi-turn mounts (RF Patent No. 2399518, publ. 09/20/2010; RF Patent No. 108372, publ. 09/20/2011), which is a folding emphasis with freely moving vertical pins that drive into the platform floor and fix with special devices (clamps). The disadvantages of this technical solution are: complex manufacturing technology and the use of non-standard parts in the manufacture of the kit; the use of several kit accessories to fix one wheel; the need for a sufficiently large time for fixing equipment; unreliability of safety during prolonged use.

The task the utility model is aimed at is: reducing the time by 3-6 times both for loading and unloading wheeled vehicles on railway platforms; the use of inexpensive materials in the manufacture of devices, which will lead to a reduction in the price of the product; the kit should be transported by car, while having moderate dimensions and weight; must be multi-turn and reusable; to reliably hold the equipment from longitudinal and transverse movements along and respectively across the platform.

This problem is solved due to the fact that the claimed device for accelerated fastening of wheeled vehicles on railway platforms, characterized in that it includes a base 1, consisting of two longitudinal and two transverse steel corners, interconnected with the possibility of fitting one part to another with a welded joint moreover, the supporting frame 2 is fixed with a stop 3 and with the base 1 pivotally using the fingers 4, and the supporting frame 2 and the stop 3 in working condition are at a certain angle.

A device for accelerated fastening of wheeled vehicles on railway platforms can be made from one assembly unit; as a material, angle steel can be used, which will lead to a reduction in the price of the product; the wheels can be fixed with vertical shelves of the corner of the base 1, support frames 2, stops 3, screeds 5 and pins 6. The wheels are additionally fixed as follows: during tightening, the rubber tire of the wheel is elasticly deformed, and the stops 3 are obliquely cut against the wooden end of the free-wheel cuts platform flooring. After tightening the support frames 2 and fixing the oblique sections of the stops 3 in the platform deck, it is necessary to loosen the tension of the screw ties 5. In this case, the rubber tire, trying to return to its shape before deformation, transfers pressure through the support frames 2 to the stops 3 and additionally presses them into the floorboards .

The technical result provided by the given set of features is the simplicity of the design of the proposed device, reliable fixation of equipment on platforms and the ability to withstand the arising loads when the train is moving, the use of this device for loading and unloading equipment will take a much shorter period of time than with standard fastening methods.

The essence of the utility model is illustrated by drawings, which depict:

In Fig.1 - the design of the device for one wheel. Figure 2 - Design fixtures for two wheels. The device kit consists of four devices: two for mounting the front wheels (Figure 1), two for mounting the middle and rear wheels (Figure 2). The design of the devices is similar, only the length of the device for mounting the middle and rear wheels, the rear bogie of cross-country vehicles Ural, KamAZ, more.

One of the main parts of the devices is the base 1. A welded construction made of rectangular steel in the form of a rectangle with transverse stiffeners that absorb the vertical load from the wheels of the machine, keep the lateral longitudinal angles from displacement. On the bottom side of the base 1, facing the platform floor, in the longitudinal corners and transverse stiffening ribs of the base 1, pins 6 are fixed, which are pressed into the wooden flooring of the platform under the weight of the machine and reliably hold the device from longitudinal and transverse movements.

Support frames 2 and stops 3 are movably attached from both ends of base 1 using fingers 4. Support frames 2 are connected by fingers 4 to base 1, and stops 3 are connected by similar fingers 4 to support frames 2. Support frames 2 and stops 3 are welded from a corner steel rated size. On the stops 3 for reliable fixation in the platform deck, the ends of the side corners are pointed by an oblique cut of the shelf metal at an angle of 45 degrees.

On the side of the fingers 4 connecting the supporting frames 2 and the stops 3, the thimbles of two screw ties 5 are fixed, which serve to tighten the stops 3 after installing the wheels of the machine on the base 1.

The device operates as follows:

1. The car, moving from the front (side) loading rack, stops in front of the railway platform on which it is planned to be placed; on the designated platform for mounting both devices for mounting the front wheels are stacked so that the front stops 3 are raised to the working position.

2. The machine is fed to the platform at low speed, the front wheels are rolled onto the fixture, the pins 6 of the devices are pressed into the floor of the platform, the front stop 3 is pressed into the floor by the pressure of the tires of the front wheels with oblique sections of the corner.

3. The machine brakes, marking the installation sites of devices for mounting the middle and rear wheels: from the projection of the middle wheel axis at a distance equal to the distance from the projection of the front wheel axis to the platform floor to the beginning of the support frame 2 of the front device, a mark is applied on the platform floor to the left to the right of the car.

4. The machine is fed back to such a distance that allows you to lay the device for mounting the middle and rear wheels on the platform floor.

5. Both devices are laid on the floor of the platform so that the beginnings of the bases 1 coincide with the marks made on the floor earlier;

The front stops of the 3 devices must be raised to their working position.

6. The machine, moving forward, rests against the front and middle wheels against the stops of 3 devices; pins 6 of the rear devices are pressed into the floor of the platform. The machine is braking.

7. The back stops 3 of all four devices are lifted, screw ties are tightened 5. During tightening, the rubber tire of the wheel is elasticly deformed, and the stops 3 are slanted against the free side against the wooden deck of the platform.

8. The oblique sections of the corners of the stops 3 of all devices are fixed in the floor of the platform.

9. After tightening the support frames 2 and fixing the oblique sections of the stops 3 in the platform deck, it is necessary to loosen the tension of the screw ties 5 by 2-3 turns. In this case, the rubber tire, seeking to return to its shape before deformation, transfers pressure through the support frames 2 to the stops 3 and additionally presses them into the floorboards.

10. The downshift engages, the machine remains on the parking brake.
