Background

Safe production and reliable power supply are important in the power industry, but fault power failure caused by natural disasters, equipment aging or other external influences is inevitable, and power lines usually extend from field substations which avoid densely populated areas to densely populated urban areas. When the breakdown is repaired, the breakdown repair vehicle not only needs to run on paved road surfaces such as cement roads, asphalt roads and the like, but also needs to face the field complex road surface conditions such as sand, soft soil, mud pits and the like. Particularly, after rain, a lot of roads are muddy, so that pits are easily formed, and after the wheels are moved, the wheels cannot be forced, so that the wheels are difficult to remove.

If the emergency repair vehicle cannot advance due to road conditions, the vehicle can be jacked up by using a jack, then stones, wood and the like are padded below the tire, and after the tire is supported, the jack is retracted to start the vehicle; the method can also call a partner vehicle, load a towing hook, and link the two vehicles by a steel cable so as to drive the vehicles by the partner vehicle; the mud tires (mountain tires) with good off-road performance can be replaced in advance before the emergency repair vehicle is taken out, harder tire walls and larger tire patterns can be arranged, the grip force of the tires can be increased, and the traffic capacity of the emergency repair vehicle under the bad road condition can be improved.

In order to make the technical problems, technical solutions and technical effects achieved by the present invention more clear, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Example one

Referring to fig. 1 and 2, the present embodiment provides a tire antiskid device. The tire antiskid device is used for antiskid of a tire 100 on a wheel, and includes: a tire belt 1, the tire belt 1 being capable of being fitted to the tire 100 along the outer circumferential surface of the tire 100; the elastic connecting belt 2 can penetrate through a hub 200 on the wheel; the two ends of the elastic connecting piece 3 and the elastic connecting band 2 can be connected to the tire antiskid band 1 through the pair of elastic connecting pieces 3. Wherein, the tire antiskid band 1 and the elastic connection band 2 may be made of rubber having high elasticity.

When the tire antiskid device is installed on a wheel, the tire antiskid belt 1 is attached to the tire 100 along the peripheral surface of the tire 100, the elastic connecting belt 2 passes through a hub 200 on the wheel, the extending directions of a pair of elastic connecting pieces 3 at the end parts of the elastic connecting belt 2 mutually form an angle, and the distance between the end parts of the pair of elastic connecting pieces 3 facing the tire antiskid belt 1 is larger than that between the end parts of the elastic connecting pieces 2. The elastic connecting band 2 penetrates through the through holes 201 between the spokes on the hub 200, and two ends of the elastic connecting band 2 respectively extend out of the through holes 201 between the spokes.

In this embodiment, each pair of elastic connecting members 3 for connecting the anti-skid band 1 and the elastic connecting band 2 can greatly tighten the anti-skid band 1 due to the arrangement form and the position relationship, and the stress is balanced, so that the elastic connecting members can adapt to the adaptive elastic deformation of the anti-skid band 1 under the extreme condition. The tyre antiskid belt 1 is sleeved on the wheel through the elastic connecting belt 2 arranged on the through hole 201 between the vehicle wheel and the wheel, and the dismounting is very convenient. Particularly, under the limit working condition, if the tire anti-skid belt 1 is subjected to larger resistance, the elastic connecting piece 3 can fail due to tearing, and the tire anti-skid belt 1 and the elastic connecting belt 2 are generally not damaged; moreover, the elastic connecting piece 3 has lower cost and smaller volume compared with the tire antiskid belt 1 and the elastic connecting belt 2, and can store a plurality of spare parts.

In the present embodiment, by mounting the tire strip 1 on the tire 100 of the wheel, the anti-skid performance of the wheel can be enhanced to suit a special road condition. One side surface of the tire antiskid belt 1 is a mounting surface which is used for being in contact fit with the outer peripheral surface of the tire 100 and is provided with antiskid fine lines; the other side surface of the tyre antiskid band 1 is an antiskid surface used for matching with the road surface, and the antiskid surface is provided with a group of first stripes 11 'and a group of second stripes 12' so as to increase the gripping performance of the tyre antiskid band 1.

Specifically, the first stripe 11 'and the second stripe 12' are arranged in a staggered manner along the length direction of the tire belt 1; the first stripes 11 'are arranged on one side of the antiskid surface and are uniformly distributed along the edge of one side of the antiskid belt 1 of the tire, and the second stripes 12' are arranged on the other side of the antiskid surface and are uniformly distributed along the edge of the other side of the antiskid belt 1 of the tire; the first strip 11 'is arranged obliquely to the side facing away from the second strip 12', and the second strip 12 'is arranged obliquely to the side facing away from the first strip 11'. Wherein, the first stripe 11 'and the second stripe 12' are both very coarse, so as to increase the friction by increasing the roughness of the non-skid surface of the tire belt 1; alternatively, the protruding height may be 2-5 cm, the width may be 2-4 cm, and the gap between two adjacent first stripes 11 'is consistent with the width thereof, and the gap between two adjacent second stripes 12' is consistent with the width thereof.

Still referring to fig. 1 and 2, elastic connection pieces 11 are respectively disposed at both sides of the tire anti-skid band 1, the elastic connection pieces 11 can be connected to one end of the elastic connection band 2 through a pair of elastic connection pieces 3, and the elastic connection pieces 11 are in one-to-one correspondence with the end portions of the elastic connection band 2. The elastic web 11 is W-shaped, and the elastic web 11 has three bottom edges 111 connected to the tire tread strip 1 and two protrusions 112 arranged away from the tire tread strip 1, the two protrusions 112 being each for connection with one elastic connection element 3. Wherein, the elastic connecting piece 11 is also made of rubber and is integrally formed with the tire antiskid band 1, and can disperse the pulling force from the elastic connecting piece 3.

Specifically, each tire anti-skid band 1 is provided with four elastic connecting sheets 11, two elastic connecting sheets 11 are arranged near one end of the tire anti-skid band 1, and the other two elastic connecting sheets 11 are arranged near the other end of the tire anti-skid band 1. On each elastic connecting piece 11, a triangular hollow part is arranged between two adjacent bottom edges 111 in the three bottom edges 111; a triangular hollow is arranged between the two protrusions 112. When the tire antiskid device is installed on a wheel, the tire antiskid belt 1 is sleeved on the tire 100, and the tire 100 is also clamped between the elastic connecting sheets 11 at two sides of the tire antiskid belt 1; the arrangement of the W-shaped structure and the triangular hollow-out structure is beneficial to the elastic scaling of the elastic connecting sheet 11 and the adaptive change of the distance between the two bulges 112.

Referring to fig. 3 and 4, the elastic link 3 includes a tension spring 30, and a stretching direction of the tension spring 30 is overlapped with an extending direction of the elastic link 3. The elastic connector 3 further comprises a first hook 31 and a second hook 32 arranged at the end of the tension spring 30, the tension spring 30 can be connected to the protrusion 112 through the first hook 31, and the tension spring 30 can be connected to the elastic connection belt 2 through the second hook 32. Wherein, the bulge 112 is provided with a first ring 10, and the end part of the elastic connecting belt 2 is provided with a second ring 20; the first hook 31 can be fitted over the first ring 10 and the second hook 32 can be fitted over the second ring 20.

Specifically, the first hook 31 and the second hook 32 are integrally formed with the tension spring 30, the elastic connecting piece 3 realizes an elastic expansion function through the tension spring 30, and convenient combination and disassembly with the tire antiskid belt 1 and the elastic connecting belt 2 are realized through the matching of the hooks and the rings; by selecting different sizes of the tension springs 30 and the first and second hooks 31 and 32, the elastic connection member 3 can be adapted to different sizes of the tire 100.

Referring to fig. 5, 6 and 7, in the present embodiment, the hub 200 of the wheel is provided with six inter-spoke through holes 201; three sets of tire antiskid devices are required, and the length of the tire belt 1 in each set of tire antiskid device is one third of the circumference of the outer circumferential surface of the tire 100 of the wheel. In this embodiment, a specific mounting method of the tire antiskid device is as follows:

when the tire 100 of the wheel sinks into mud or loosens the soil on the road surface 1000, the tire anti-skid band 1 can be sleeved on the front side of the tire 100 relative to the advancing direction of the vehicle, and the two protrusions 112 of each elastic connecting sheet 11 point to the corresponding spoke through holes 201 together so as to be connected with the elastic connecting belt 2 which is arranged in the spoke through holes 201 (see fig. 1); after the first section of tire anti-skid belt 1 is installed, the accelerator is slightly stepped to enable the tire 100 to rotate by one third of the circumference, then the next section of tire anti-skid belt 1 is installed until the three sets of tire anti-skid devices are all installed on the tire 100, and the full coverage of the three sections of tire anti-skid belts 1 on the outer circumferential surface of the tire 100 is realized.

In fact, if the wheel with three or five through holes 201 between spokes is provided, by selecting the elastic connecting element 3 with proper size, the tire antiskid device can be installed on the wheel by combining the installation method; the length of the tire belt 1 in the tire antiskid device is designed according to specific use requirements for wheels with different diameters. In practical application, compared with the tire antiskid belt 1 and the elastic connecting belt 2, only the elastic connecting piece 3 is a vulnerable part, and the tire antiskid device is usually arranged on the driving wheel of the vehicle, so that two sets of the tire antiskid devices and a small number of spare parts of the elastic connecting piece 3 are required to be prepared, and the tire antiskid device is very convenient to carry. Moreover, in case of emergency, the elastic connecting piece 3 can be replaced by a self-locking cable tie.
