Description

Technical Field

[0001] This utility model relates to the field of transportation, and in particular to a self-dumping semi-trailer with an anti-skid structure. Background Technology

[0002] A dump semi-trailer is a common type of transport vehicle, mainly used for transporting bulk materials. It consists of a trailer and a semi-trailer. The trailer is connected to the tractor unit via a hook, while the semi-trailer is supported on the ground through the connection point with the trailer. The characteristic of a dump semi-trailer is its ability to unload goods by tipping over or bottoming out, which is convenient and quick.

[0003] During the transportation of bulk materials using dump semi-trailers, the materials inside the cargo bed are prone to relative slippage due to the characteristics of the materials, road conditions, and driving operations. This can not only lead to uneven loading and increase the risk of rollover during vehicle operation, but also cause structural damage to the vehicle body due to the material sliding and impacting the inner wall of the cargo bed, thus shortening the overall service life of the semi-trailer. Traditional dump semi-trailers typically have several anti-slip bars fixedly installed on the inner wall of the cargo bed to prevent the materials from sliding during tilting, using physical friction. However, over time, the anti-slip bars on the inner wall of the cargo bed will gradually wear down, resulting in a decrease in anti-slip effectiveness, shortening the service life of the anti-slip bars, increasing maintenance frequency and costs, and reducing the working efficiency and long-term stability of the dump semi-trailer. Utility Model Content

[0004] The technical problem this utility model aims to solve is that during the transportation of bulk materials by dump semi-trailers, the materials inside the cargo bed are prone to relative slippage due to the characteristics of the materials, road conditions, and driving operations. This can not only lead to uneven loading of materials, increasing the risk of rollover during vehicle operation, but also cause damage to the vehicle body structure due to the sliding and impact of the materials on the inner wall of the cargo bed, thus shortening the overall service life of the semi-trailer. Traditional dump semi-trailers usually have several anti-slip bars fixedly installed on the inner wall of the cargo bed to prevent the materials from sliding during tilting using physical friction. However, as time goes by, the anti-slip bars on the inner wall of the cargo bed will gradually wear down, resulting in a decrease in the anti-slip effect, shortening the service life of the anti-slip bars, increasing the maintenance frequency and cost, and reducing the working efficiency and long-term stability of the dump semi-trailer.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a self-unloading semi-trailer with an anti-slip structure, including a semi-trailer body, a cargo basket rotatably installed on one side of the semi-trailer body, a hydraulic rod rotatably installed on the inner wall of one side of the semi-trailer body, the output end of the hydraulic rod rotatably installed in the inner wall of one side of the cargo basket, and an anti-slip device provided on one side of the inner wall of the cargo basket. The anti-slip device can increase the contact friction of the inner wall of the cargo basket by setting several anti-slip rods to achieve the anti-slip effect. At the same time, when the anti-slip effect is reduced due to wear, the screw can be rotated to drive the abutment frame to slide to one end to push the abutment block and the anti-slip rod to move upward to a certain height, thereby increasing the contact friction and improving the anti-slip effect.

[0006] Preferably, the anti-slip device includes several anti-slip rods, several rectangular grooves are formed on one side of the inner wall of the basket, and a sliding groove is formed on one side of the basket, wherein the anti-slip rods are slidably installed in the inner wall of the rectangular grooves; several first springs, wherein the two ends of the first springs are respectively fixedly installed on one side of the inner wall of the sliding groove and one side of the anti-slip rods; several abutment blocks, wherein one end of the abutment block is fixedly installed on one side of the anti-slip rod, and the other end extends through one side of the inner wall of the rectangular groove into the inner wall of the sliding groove; an abutment frame, wherein the abutment frame is slidably installed in the inner wall of the sliding groove, and both ends abut against one side of the several abutment blocks; a lead screw, wherein one end of the lead screw is installed through one side of the inner wall of the sliding groove, and its outer surface is threadedly connected to the inner wall of one end of the abutment frame; and a limiting mechanism, wherein the limiting mechanism is disposed between one end of the lead screw and one side of the basket, for limiting and fixing the rotated lead screw.

[0007] The aforementioned components achieve the following effects: By incorporating an anti-slip device, during the transportation of bulk materials in a dump semi-trailer, the bulk materials are placed inside the cargo compartment. Several anti-slip bars increase the contact friction on the inner wall of the compartment, preventing the bulk materials from sliding inside and improving transportation stability and safety. When the anti-slip bars wear down after prolonged use, the screw can be manually rotated to slide the abutment frame in the groove to one end to a certain position. The two ends abut against and push several abutment blocks upwards, causing the anti-slip bar to slide upwards in the rectangular groove. This stretches the first spring between the anti-slip bar and the groove on one side. A limiting mechanism then limits and fixes the rotated screw, allowing the anti-slip bar to automatically restore its anti-slip effect. This design not only extends the service life of the anti-slip device but also reduces maintenance frequency and costs, improving the working efficiency and long-term stability of the dump semi-trailer. Finally, during unloading, the hydraulic rod on the semi-trailer body can be activated to cause the trailer to rotate around one end of the semi-trailer body, which will tilt and dump the bulk materials transported inside, thus achieving the unloading effect.

[0008] Preferably, the limiting mechanism includes a locking block, wherein one end of the locking block is slidably installed in the inner wall of one end of the lead screw, and a plurality of locking slots are provided on one side of the cart, wherein one end of the locking block is inserted into the inner wall of the locking slot; and a second spring, wherein the inner wall of the second spring is sleeved on the outer surface of one end of the locking block, and both ends are respectively fixedly installed on one side of the locking block and one side of the lead screw.

[0009] The effect achieved by the above-mentioned components is as follows: by setting a limiting mechanism, when it is necessary to rotate the lead screw, the locking block can be pulled outward to a certain position in the inner wall of one end of the lead screw, which will cause the second spring to be stretched open, so that one end of the spring is pulled out of the slot. Then, after rotating the lead screw, the locking block is released, so that it can be locked into the corresponding slot under the reset action of the second spring, thus limiting and fixing the lead screw, making it less likely to loosen due to self-rotation after adjustment, thereby improving the adjustment and anti-slip effect.

[0010] Preferably, the limiting mechanism further includes a pull block, wherein the outer surface of the pull block is fixedly mounted on one side of the locking block.

[0011] The effect achieved by the above components is that by setting up the pull block, the contact area on one side of the locking block can be increased, making it easier to manually hook one side when rotating the screw, thus facilitating operation.

[0012] Preferably, a plurality of anti-slip protrusions are fixedly installed on one side of the anti-slip rod, and the anti-slip protrusions are located on the side of the anti-slip rod away from the first spring.

[0013] The effect achieved by the above components is as follows: by setting anti-slip protrusions, the roughness of one side of the anti-slip rod can be increased, the friction can be improved, the anti-slip rod can be protected on one side, the wear time can be increased, and the service life can be improved.

[0014] Preferably, several round rollers are rotatably installed on several sides of both ends of the abutment frame, wherein the round rollers roll and abut against one side of the abutment block.

[0015] The effect achieved by the above components is as follows: by setting the roller, the contact friction between the abutment frame and the abutment block can be reduced, making it easier for the abutment frame to push the abutment block, facilitating adjustment operations, and improving the service life of both.

[0016] Preferably, the anti-slip device further includes a plurality of telescopic rods, wherein the outer surface of the telescopic rods is inserted into the inner wall of the first spring, and both ends are respectively fixedly installed on one side of the slide groove and one side of the anti-slip rod.

[0017] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the first spring can be supported and reinforced, making it less prone to damage during use and increasing its service life.

[0018] The beneficial effects of this utility model are:

[0019] By incorporating an anti-slip device, when transporting bulk materials in a dump semi-trailer, the bulk materials are placed inside the cargo compartment. Several anti-slip bars increase the contact friction on the inner wall of the compartment, preventing the bulk materials from sliding inside and improving transportation stability and safety. When the anti-slip bars wear out over time, the screw can be manually rotated to slide the abutment frame in the groove to one end to a certain position. The two ends can then abut against several abutment blocks, causing the anti-slip bar to slide upwards in the rectangular groove. This stretches the first spring between the anti-slip bar and the groove on one side. Then, a limiting mechanism limits and fixes the rotated screw, allowing the anti-slip bar to automatically restore its anti-slip effect. This design not only extends the service life of the anti-slip device but also reduces maintenance frequency and costs, improving the working efficiency and long-term stability of the dump semi-trailer.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1-6 The illustrated dump semi-trailer with an anti-slip structure includes a semi-trailer body 1. A cargo bed 3 is rotatably mounted on one side of the semi-trailer body 1. A hydraulic rod 4 is rotatably mounted on the inner wall of one side of the semi-trailer body 1. The output end of the hydraulic rod 4 is rotatably mounted in the inner wall of one side of the cargo bed 3. An anti-slip device 2 is provided on one side of the inner wall of the cargo bed 3. The anti-slip device 2 increases the contact friction of the inner wall of the cargo bed 3 by setting several anti-slip rods 23 to achieve the anti-slip effect. At the same time, when the anti-slip effect is reduced due to wear, the screw 27 can be rotated to drive the abutment frame 26 to slide to one end to push the abutment block 25 and the anti-slip rods 23 upward to a certain height, thereby increasing the contact friction and improving the anti-slip effect. It should be noted that the semi-trailer body 1 and the hydraulic rod 4 are mature technologies and equipment in the prior art, and their internal structure, connection method and principle will not be described further.

[0031] Figure 1-6The anti-slip device 2 shown includes several anti-slip rods 23, several rectangular grooves 21 are formed on one side of the inner wall of the basket 3, and a sliding groove 22 is formed on one side of the basket 3. The anti-slip rods 23 are slidably installed in the inner wall of the rectangular grooves 21; several first springs 24 are provided, with both ends of the first springs 24 being fixedly installed on one side of the inner wall of the sliding groove 22 and one side of the anti-slip rods 23, respectively; and several abutment blocks 25 are provided, with one end of the abutment block 25 being fixedly installed on one side of the anti-slip rod 23, while the other end passes through the rectangular groove. The inner wall of 21 extends to the inner wall of the slide 22; the abutment frame 26 is slidably installed in the inner wall of the slide 22, and its two ends abut against one side of a plurality of abutment blocks 25; the lead screw 27 is installed through one end of the inner wall of the slide 22, and its outer surface is threaded to the inner wall of one end of the abutment frame 26; the limiting mechanism 28 is disposed between one end of the lead screw 27 and one side of the cart 3, and is used to limit and fix the rotated lead screw 27. By setting up the anti-slip device 2, during the transportation of bulk materials using a dump semi-trailer, the bulk materials are placed inside the cargo compartment 3. Then, with the help of several anti-slip bars 23, the contact friction of the inner wall of the cargo compartment 3 is increased, making it difficult for the bulk materials to slide inside the cargo compartment 3, thus improving transportation stability and safety. When the anti-slip bars 23 wear out after prolonged use, the screw 27 can be manually rotated to drive the abutment frame 26 to slide to one end in the slide groove 22 to a certain position. The two ends can abut against and push several abutment blocks 25 to move upward, causing the anti-slip bar 23 to slide upward in the rectangular groove 21. This stretches the first spring 24 between the anti-slip bar 23 and the slide groove 22. Then, the limiting mechanism 28 limits and fixes the rotated screw 27, so that the anti-slip bar 23 can automatically restore its anti-slip effect. This design not only extends the service life of the anti-slip device 2, but also reduces the maintenance frequency and cost, and improves the working efficiency and long-term stability of the dump semi-trailer. Finally, during unloading, the hydraulic rod 4 on the semi-trailer body 1 can be activated to drive the trailer 3 to rotate around one end of the semi-trailer body 1, which will tilt and pour out the bulk materials transported inside, thus achieving the effect of unloading.

[0032] Figure 1-6The limiting mechanism 28 shown includes a locking block 282, one end of which is slidably mounted in the inner wall of one end of the lead screw 27. A plurality of locking slots 281 are provided on one side of the cart 3, and one end of the locking block 282 is inserted into the inner wall of the locking slot 281. A second spring 283 is provided, the inner wall of which is sleeved on the outer surface of one end of the locking block 282, and both ends are fixedly mounted on one side of the locking block 282 and one side of the lead screw 27, respectively. By setting a limiting mechanism 28, when the lead screw 27 needs to be rotated, the locking block 282 can be pulled outward in the inner wall of one end of the lead screw 27 to a certain position, which will cause the second spring 283 to be stretched open, so that one end of it is pulled out of the slot 281. Then, after rotating the lead screw 27, the locking block 282 is released, so that it can be locked into the corresponding slot 281 under the reset action of the second spring 283, thus limiting and fixing the lead screw 27, making it less likely to loosen due to self-rotation after adjustment, and improving the adjustment and anti-slip effect.

[0033] Figure 1-6 The limiting mechanism 28 shown also includes a pull block 284, the outer surface of which is fixedly mounted on one side of the locking block 282. By setting the pull block 284, the contact area on one side of the locking block 282 can be increased, making it easier to manually hook one side when rotating the lead screw 27, thus facilitating operation.

[0034] Figure 1-6 Several anti-slip protrusions 29 are fixedly installed on one side of the anti-slip rod 23, and the anti-slip protrusions 29 are located on the side of the anti-slip rod 23 away from the first spring 24. By setting the anti-slip protrusions 29, the roughness of one side of the anti-slip rod 23 can be increased, the friction can be improved, and one side of the anti-slip rod 23 can be protected, increasing the wear time and service life. Several rollers 210 are rotatably installed on several sides of both ends of the abutment frame 26, and the rollers 210 roll against one side of the abutment block 25. By setting the rollers 210, the contact friction between the abutment frame 26 and the abutment block 25 can be reduced, making it easier for the abutment frame 26 to push the abutment block 25, facilitating adjustment, and improving the service life of both. The anti-slip device 2 also includes several telescopic rods 211, the outer surface of which is inserted into the inner wall of the first spring 24, and both ends are fixedly installed on one side of the slide groove 22 and one side of the anti-slip rod 23, respectively. By setting the telescopic rod 211, the inner wall of the first spring 24 can be supported and reinforced, making it less prone to damage during use and extending its service life.

[0035] Working principle: When transporting bulk materials using a dump semi-trailer, the bulk materials are placed inside the cargo compartment 3. Several anti-slip bars 23 increase the contact friction on the inner wall of the cargo compartment 3, preventing the bulk materials from sliding inside and improving transport stability and safety. When the anti-slip bars 23 wear out over time, the locking block 282 is pulled outward from the inner wall of one end of the screw 27 to a certain position, causing the second spring 283 to be stretched open, allowing one end to be pulled out of the slot 281. Then, the screw 27 is manually rotated, causing the abutment frame 26 to slide in the groove 22 to a certain position. The anti-slip rod 23 is positioned such that several abutment blocks 25 at both ends can be pushed upwards, causing the anti-slip rod 23 to slide upwards in the rectangular groove 21. This stretches the first spring 24 between the anti-slip rod 23 and the groove 22. Then, by releasing the locking block 282, it can be locked into the corresponding slot 281 under the reset action of the second spring 283, thus limiting and fixing the lead screw 27. This allows the anti-slip rod 23 to automatically restore its anti-slip effect. This design not only extends the service life of the anti-slip device 2 but also reduces maintenance frequency and costs, improving the working efficiency and long-term stability of the dump semi-trailer. Finally, during unloading, the hydraulic rod 4 on the semi-trailer body 1 can be activated to rotate the cargo bag 3 around one end of the semi-trailer body 1, tilting and emptying the bulk materials transported inside, achieving the unloading effect.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
