Description

A flexible gangway (hereinafter referred to as the device) relates to vehicles, in particular, to devices that prevent slipping of wheels and skidding of vehicles.

A device is known, which is a U-shaped tray with two ramps to enter this device, with spikes on the surface of the tray and made of material that allows you to twist this device into a roll. Patent US8448877 B1 (2013.05.28). The disadvantages of this device are:

- the flexibility of the tray, bending under the weight of the stalled vehicle and, as a result, reducing the contact area of the device and the ground:

- the inability to connect, if necessary, to this device a similar device for lengthening and fixing this device relative to the ground;

- the complexity of the institution of this device under the skidding wheel of the vehicle.

A device is known consisting of rubber blocks, the supporting surfaces of which are provided with anti-slip strips strung on flexible steel ropes. The ends of the ropes are interconnected. Patent CN 202345313U (2011.07.25). The disadvantages of this device are:

- the flexibility of rubber blocks bending under the weight of a stalled vehicle and, as a result, a decrease in the contact area between the device and the ground:

- the inability to connect, if necessary, to this device a similar device for lengthening and fixing this device relative to the ground

- the complexity of the institution of this device under the skidding wheel of the vehicle.

The closest known analogues is a device consisting of blocks made in the form of rectangular metal pipes drilled and strung on flexible steel ropes. Each block is fixed relative to the ropes on both sides with special clamps, and the blocks do not touch each other and are at a certain distance from each other. On one side of the device, steel hooks and rings are attached to the ends of the steel ropes. These steel hook and ring are used to attach the device to the wheel by the spoke of the wheel disc. Patent CN108528155 A (2018.09.14). This device has several disadvantages:

- some wheel disks are equipped not with spokes, but with small holes that do not allow this device to be hooked on the vehicle’s stalled wheel;

- the hook-ring connection is not reliable, as when the wheel rotates, the hook may pop out of the ring;

- The metal rope, hook and ring can damage the drive and tire of the vehicle.

This device is selected as a prototype.

The purpose of the claimed utility model are:

- ensuring reliable adhesion of the surface of this device to the ground, increasing the contact area of the device and the ground;

- weight reduction device:

- improving the reliability of mounting the device to the wheel, mounting the device to wheels with different design of disks;

- elimination of damage to the drive and tires of vehicles.

The goal is achieved by the fact that:

- the blocks are strung on flexible steel ropes almost close to each other with small gaps, providing the possibility of folding the device into a roll;

- the blocks are made of monolithic profiled by extrusion from durable plastic;

- the device is equipped with a mounting unit to the wheel, made in the form of a flexible element with a hook;

- the device is attached to the wheel with an elastic durable belt.

The essence and operation of the proposed device are illustrated by the following images:

FIG. 1 - general view of the device

FIG. 2 - use of the device as a traction tape

FIG. 3 - use the device as a ladder

The device consists of a set of monolithic profiled rigid blocks 1 strung on flexible steel ropes 2, node 3, which allows to attach a similar device to this device or fix the device relative to the ground, node 4, made in the form of a flexible element with a hook 5, which ensures reliable fastening of the device to the surface of the tread and the institution of the device under the skidding wheel of the vehicle, clamps 6, crimped at the ends of flexible steel ropes.

The device used as a traction tape, operates as follows. To the tread of the stalled wheel 7 (see Fig. 2) with the help of a belt 8, passed into the disk window, a patented device is attached so that the belt 8 touches the hook. The other end of the device is fixed relative to the ground by the latch 9. When starting the vehicle, the wheel starts to rotate in the direction indicated by the arrow, pulls the device underneath and bumps into it. After hitting a device, the wheel begins to move along the surface of the device, winding it onto itself and moving the stalled vehicle.

The device used as a ladder works as follows.

To the tread of the stalled wheel 7 (see Fig. 2) with the help of a belt 8, passed into the disk window, a patented device is attached so that the belt 8 touches the hook. When starting the vehicle, the wheel starts to rotate in the direction indicated by the arrow, pulls the device underneath and bumps into it. After hitting a device, the belt is removed (see Fig. 3) and the wheel begins to move along the surface of the device. If you need significant movement on sand or waterlogged soils using a bolted connection 10, you can attach a similar device to this device.

The use of this device allows you to increase the contact area of the device and the ground and attach a similar device to this device or fix the device relative to the ground, attach the device to wheels with different design of disks, facilitates the device under the skidding wheel of the vehicle, eliminates the possibility of damage to the disks and tires of the vehicle, increases the reliability of mounting the device to the wheel.

Claims (1)
