Description

Technical Field

[0001] The utility model relates to the field of anti-skid for wheeled vehicles in winter, in particular to an auxiliary passing device for tires, especially an auxiliary passing device suitable for wheeled vehicles on ice and snow roads. Background Art

[0002] At present, under the action of the winter snow weather environment, when snow removal is not timely, the road surface often freezes. Wheeled vehicles are prone to skidding when driving on the frozen road surface. Especially for heavy-duty wheeled vehicles, when encountering a sloping road surface or during a turning process, the tires will skid and cannot move forward when rubbing against the ice surface on the road surface. At this time, materials and personnel cannot reach the accident site in the first time. If pushed by manpower, it is very easy to cause safety accidents. In order to avoid accidents, anti-skid chains are installed on the tires of many wheeled vehicles. The existing tire anti-skid chains use a lightweight anti-skid chain wound around the tire. Its principle is: concentrating the gravity of the vehicle on several points of the lightweight anti-skid chain to generate a huge pressure, penetrating through the ice and snow layer to reach the road surface, thereby increasing the friction force and the safety factor of vehicle driving. However, the reliability of this kind of anti-skid chain is not strong, the number of uses is limited, the service life is low, and there will still be a phenomenon of tire skidding. Summary of the Invention

[0003] The purpose of the utility model is to provide an auxiliary passing device suitable for wheeled vehicles on ice and snow roads, and solve the problems such as insufficient friction force and poor climbing ability existing in the commonly used anti-skid chains for heavy-duty wheeled vehicles.

[0004] The above object of the utility model is achieved by the following technical solutions:

[0005] An auxiliary passage device applicable to wheeled vehicles on ice and snow roads, including four groups of anti-slip mechanisms and four groups of locking mechanisms. The anti-slip mechanism is composed of a left rubber connecting plate 1, a right rubber connecting plate 2, an anti-slip chain 4, and anti-slip nails 3. Each group of anti-slip mechanisms is equipped with four anti-slip nails 3. Four hanging holes are evenly distributed on the upper end surface of the anti-slip nails 3, and an anti-slip chain 4 is equipped on each hanging hole. The four anti-slip nails 3 are connected into one body through the anti-slip chain 4. Among them, the hanging holes of the anti-slip nails 3 close to the left rubber connecting plate 1 and the right rubber connecting plate 2 are connected to the upper ends of the left and right rubber connecting plates through the anti-slip chain 4. The left and right rubber connecting plates and each anti-slip nail 3 are connected into a whole through the anti-slip chain 4 to form an anti-slip mechanism, and the anti-slip mechanism is locked on the tire surface by the locking mechanism. The locking mechanism is composed of a rope 5, a positioning pin 6, a split pin 7, and a lock 8. After the positioning pin 6 is inserted into the through hole of the lock 8, the split pin 7 is inserted into the through hole at the tail of the positioning pin 6 to prevent the positioning pin from axially moving. One end of the rope 5 is connected to the bottom of the right rubber connecting plate 2 through an iron ring, and the other end of the rope 5 is inserted into the through hole in the middle of the positioning pin 6. By twisting the positioning pin 6 in the through hole of the lock 8, the rope 5 is tensioned, and then the anti-slip mechanism is firmly locked in the hub gap.

[0006] The anti-slip nails in the anti-slip mechanism can overall form a uniformly distributed nail array. As the wheel rotates, the nail array can always keep in contact with the ground, making the adhesion between the wheel and the ground stronger. The upper end surface of the anti-slip nail is made into an arc surface that fits the tire surface. Four hanging holes are made on the arc surface, and reinforcing ribs are made between the upper end surface and the middle part. The middle part is a triangular prism structure, and the bottom is a conical structure.

[0007] The anti-slip chain 4 is a lightweight anti-slip chain, and its material is a high-elastic rubber material, which has the characteristics of wear resistance, corrosion resistance, and light weight. It can increase the contact area between the anti-slip chain and the ground, improve the anti-slip performance and driving comfort.

[0008] The beneficial effects of the present utility model are as follows: novel in concept, simple in structure, and convenient to use. It can effectively pass through ice and snow roads, frozen roads, and icy roads, cause little damage to the road surface, provide reliable reaction forces, and is beneficial for long-distance driving. The fixed locking effect is good, and it will not fall off during long-distance driving. Moreover, this auxiliary passage device can be quickly installed and quickly disassembled, reducing the work intensity of the crew. It can be widely applied to the driving of wheeled vehicles on ice and snow roads, and has strong practicability. Brief Description of the Drawings

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0015] See Figures 1 to 3As shown in the figure, the auxiliary passage device of the utility model applicable to wheeled vehicles on ice and snow roads includes four groups of anti-slip mechanisms and four groups of locking mechanisms. The anti-slip mechanism consists of a left rubber connecting plate 1, a right rubber connecting plate 2, anti-slip nails 3, and anti-slip chains 4. According to the installation requirements, each anti-slip nail is tensioned by four anti-slip chains, so that the upper end surface of the anti-slip nail is closely attached to the tire surface. The tensioning of the anti-slip chain is completed by locking the two rubber connecting plates through the locking mechanism. Each group of anti-slip mechanisms is equipped with four anti-slip nails 3. Four hanging holes are evenly distributed on the upper end surface of the anti-slip nails 3, and each hanging hole is equipped with an anti-slip chain 4. The four anti-slip nails 3 are connected into one body through the anti-slip chain 4. Among them, the hanging holes of the anti-slip nails 3 close to the left rubber connecting plate 1 and the right rubber connecting plate 2 are connected to the connecting hanging holes at the upper ends of the left and right rubber connecting plates through the anti-slip chain 4, and the anti-slip chains on the hanging holes of the remaining anti-slip nails are connected to the hanging holes of other anti-slip nails. The left and right rubber connecting plates and each anti-slip nail 3 are connected into a whole through the anti-slip chain 4 to form an anti-slip mechanism, and the anti-slip mechanism is locked on the tire surface by the locking mechanism. The locking mechanism consists of a rope 5, a positioning pin 6, a split pin 7, and a lock 8, which is used to lock the anti-slip mechanism and make it firmly fixed on the tire surface. After the positioning pin 6 is inserted into the through hole of the lock 8, the split pin 7 is inserted into the through hole at the tail of the positioning pin 6 to prevent the positioning pin from axially moving. One end of the rope 5 is connected to the bottom of the right rubber connecting plate 2 through an iron ring, and the other end of the rope 5 is inserted into the through hole in the middle of the positioning pin 6. By twisting the positioning pin 6 in the through hole of the lock 8, the rope 5 is tensioned, so as to firmly lock the anti-slip mechanism in the hub gap, prevent the auxiliary passage device from falling off due to too fast wheel speed, and at the same time facilitate the installation and disassembly of the auxiliary passage device. The auxiliary passage device of the utility model can effectively pass through ice and snow roads, frozen roads, and icy roads, cause little damage to the road surface, provide reliable reaction force, and is beneficial for long-distance driving; it has good fixing effect and will not fall off during long-distance driving, and the auxiliary passage device can be quickly installed and quickly disassembled, reducing the working intensity of the crew.

[0016] The lower part of the anti-slip nail 3 is conical, so that the anti-slip nail can be quickly nailed into the ice surface; the middle part of the anti-slip nail 3 is a triangular prism, which can make the vehicle pass with better ice-breaking adhesion as the wheel rotates, thereby increasing the friction between the wheel and the ground; the middle and top of the anti-slip nail are designed with reinforcing rib round corners, mainly to reduce the shear stress generated on the head of the anti-slip nail during the driving process of the wheeled vehicle. The upper end surface of the anti-slip nail is made into an arc surface that fits the tire surface, in order to better fit the tire surface and not generate concentrated stress on the tire surface; all the anti-slip nails in each anti-slip mechanism form a uniformly distributed nail array, and this structure can damage the surface structure of the road surface as small as possible, which is beneficial for the following vehicle to pass continuously.

[0017] The anti-skid chain 4 described above is a lightweight anti-skid chain, which has the characteristics of wear resistance, low temperature resistance, high tensile strength, strong anti-shear ability, lightweight, etc., facilitating movement with the wheels and reducing the power consumption of the vehicle engine.

[0018] See Figures 1 to 3 As shown, when the auxiliary passage device of the utility model applicable to wheeled vehicles on ice and snow roads is actually used, the four anti-skid nails 3 in each anti-skid mechanism are arranged in a staggered manner, and each anti-skid nail is connected by an anti-skid chain. The anti-skid nail 3 is connected to the left connecting plate 1 or the right connecting plate 2 through a lightweight anti-skid chain. After all the anti-skid nails 3, anti-skid chains 4 and connecting plates are connected, the rope 5 with an iron ring at one end is sleeved at the bottom through hole of the left connecting plate 1, and the other end of the rope 5 extends out from the middle through hole of the positioning pin 6. Use a flat head screwdriver to rotate the head groove of the positioning pin 6 clockwise to lock the rope 5 in the locking device 8, so that the anti-skid nail 3 is tightened on the tire surface by the left rubber connecting plate 1 and the right connecting plate 2, achieving the locking effect. This device enables wheeled vehicles to pass through frozen driving roads in a short time and effectively ensures road traffic safety.

For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made to the utility model shall be included within the protection scope of the utility model.
