Technical Field
[0001] This utility model relates to the field of track plate connection technology, and in particular to an anti-slip rubber-coated track plate connection structure. Background Technology
[0002] In today's era of widespread application of various tracked equipment, such as excavators and bulldozers in the engineering field, and tanks and armored vehicles in the military field, the performance of the anti-slip rubber-coated track plate connection structure plays a key role in the safe and stable operation of the equipment. As a key component in contact with the ground, the rubber-coated track plate not only has to bear the weight of the equipment itself, but also has to cope with complex and ever-changing terrain and various forces generated during the operation of the equipment. The reliability of its connection structure is directly related to the overall performance of the equipment. Therefore, it is particularly important to develop an efficient and stable anti-slip rubber-coated track plate connection structure.
[0003] In existing technologies, the common anti-slip rubber-coated track plates are mostly connected using the more traditional bolt connection method. The track plates are fixed by directly passing the bolt through the pre-set connection holes on the track plate and then tightening the nut. The technical principle of this connection method is relatively simple. It mainly relies on the tightening force generated by the threaded engagement between the bolt and the nut to make the adjacent track plates tightly connected. When the equipment is running, the rubber-coated track plates propel the equipment forward by friction with the ground, while the bolt connection structure is responsible for maintaining the overall continuity and stability of the track plates.
[0004] However, this traditional bolt connection method has a significant problem. In actual operation, tracked equipment usually faces extremely complex working conditions. For example, when operating on rugged mountainous terrain, the equipment will generate severe vibrations, and the track plates will be subjected to impact and shear forces from different directions. Under such circumstances, relying solely on the connection between bolts and nuts can easily lead to loosening of the connection due to vibration and complex stress conditions. Once the bolt connection is loose, the stability of the connection between the track plates will be greatly reduced, which will affect the overall stability of the rubber-coated track plate structure, reduce the anti-slip performance of the equipment during operation, and in severe cases, even endanger the reliability of the equipment operation and cause safety accidents. Therefore, an anti-slip rubber-coated track plate connection structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an anti-slip rubber-coated track plate connection structure, which aims to improve the problem that bolted connections in the prior art are prone to loosening due to vibration and complex stress.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A non-slip rubber-coated track plate connection structure includes a track plate, a connecting ring fixedly connected to the outer wall of the track plate, a pin slidably connected inside the connecting ring, a connecting component provided on the outer wall of the pin, and a reinforcing component provided inside the pin.
[0008] The connecting assembly includes a connecting plate and a limiting groove formed inside the pin. The connecting plate is slidably connected to the outer wall of the limiting groove. One end of the pin is fixedly connected to a screw, and a nut is threaded onto the outer wall of the screw.
[0009] As a further description of the above technical solution:
[0010] The reinforcement component includes a retaining ball and an annular groove formed inside the connecting ring, with the outer wall of the retaining ball slidably connected inside the annular groove.
[0011] As a further description of the above technical solution:
[0012] The pin has a push rod that slides inside it, and a limit groove is formed inside the pin.
[0013] As a further description of the above technical solution:
[0014] The outer wall of the push rod is fixedly connected to a limiting disk, and the outer wall of the limiting disk is slidably connected inside the limiting groove.
[0015] As a further description of the above technical solution:
[0016] A spring is fitted on the outer wall of the push rod. One end of the spring is fixedly connected to the outer wall of the limiting disc, and the other end of the spring is fixedly connected to the inner wall of the pin.
[0017] As a further description of the above technical solution:
[0018] A tapered block is fixedly connected to one end of the push rod, and a limit post is fixedly connected to one end of the tapered block.
[0019] As a further description of the above technical solution:
[0020] The outer wall of the limiting post is slidably connected to the inside of the pin, and the pin is in contact with the locking ball.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the bolts are first passed through the track plate connecting ring, and then the connecting ring is put on the two adjacent bolts and fixed and the nuts are tightened. This solves the problem that the bolt connection is prone to loosening due to vibration and complex stress, improves the stability of the track plate connection, and enables the rubber-coated track plate to maintain a stable structure during operation, thereby improving the overall anti-slip performance and equipment operation reliability.
[0023] 2. In this utility model, the ball is moved by a push rod. When the push rod is pushed, it drives the conical block and the limiting post, and in conjunction with the spring, the ball slides inside the annular groove, thereby fixing the pin a second time and preventing it from sliding. This solves the problem of easy shaking inside after connection and improves the stability of the pin connection. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a non-slip rubber-coated track plate connection structure, including a track plate 1, a connecting ring 2 fixedly connected to the outer wall of the track plate 1, the connecting ring 2 being forged from high-quality carbon structural steel, having high strength and toughness, and its interior being designed as a smooth cylindrical hole, the hole diameter matching the outer diameter of the pin 4, ensuring that the pin 4 can slide freely inside the connecting ring 2, while also ensuring a tight fit to prevent shaking and loosening; the pin 4 is slidably connected inside the connecting ring 2, the outer wall of the pin 4 is provided with a connecting component, and the inside of the pin 4 is provided with a reinforcing component;
[0031] The connecting assembly includes a connecting plate 5 and a limiting groove 7 formed inside the pin 4. The connecting plate 5 is slidably connected to the outer wall of the limiting groove 7. The connecting plate 5 is made of high-strength aluminum alloy, which is lightweight and high-strength. Its internal design has a protruding structure that matches the limiting groove 7, which can be tightly slidably connected to the outer wall of the limiting groove 7 to limit and fix the pin 4. One end of the pin 4 is fixedly connected to a screw 6, and a nut 3 is threadedly connected to the outer wall of the screw 6.
[0032] Specifically, when connecting the anti-slip rubber-coated track plates 1, the first step is to precisely align the connecting rings 2 on both sides to ensure the accuracy and stability of subsequent connection operations. After alignment, the pins 4 are slowly inserted into the connecting rings 2 to initially establish a connection between the track plates 1. Then, the connecting plates 5 are used to connect the adjacent pins 4 together to further strengthen the tightness of the connection. Subsequently, the nuts 3 are screwed into the outer wall of the screw rod 6, and the limiting grooves 7 on the screw rod 6 are used to fix the entire connection structure, greatly increasing the redundancy of the connection. Even if one of the pins 4 becomes loose due to severe vibration or complex stress in actual operation, the other pin 4 can still maintain a certain connection strength with the help of the connecting rings 2, which greatly improves the stability and reliability of the entire connection structure and provides a solid guarantee for the stable operation of the anti-slip rubber-coated track plates 1 under various complex working conditions.
[0033] Reference Figure 1 and Figure 3 The reinforcing components include a retaining ball 14 and an annular groove 15 formed inside the connecting ring 2. The retaining ball 14 is made of a hard alloy with extremely high hardness and excellent wear resistance. This alloy material can withstand enormous pressure and frequent friction without easily being damaged. Its surface is finely ground to achieve an extremely low surface roughness, allowing the outer wall of the retaining ball 14 to slide smoothly inside the annular groove 15, which is made of high-strength aluminum alloy. The annular groove 15 is regularly distributed in a ring inside the connecting ring 2, and its width and depth are precisely designed to perfectly match the size of the retaining ball 14, ensuring that the retaining ball 14 can move flexibly within it while providing a reliable limiting function at specific positions. The outer wall of the retaining ball 14 is slidably connected inside the annular groove 15, and the pin 4 is slidably connected inside. There is a push rod 8, and a limiting groove 11 is opened inside the pin 4. A limiting disc 9 is fixedly connected to the outer wall of the push rod 8. The outer wall of the limiting disc 9 is slidably connected to the inside of the limiting groove 11. A spring 10 is sleeved on the outer wall of the push rod 8. One end of the spring 10 is fixedly connected to the outer wall of the limiting disc 9, and the other end of the spring 10 is fixedly connected to the inner wall of the pin 4. A conical block 12 is fixedly connected to one end of the push rod 8. A limiting post 13 is fixedly connected to one end of the conical block 12. The outer wall of the limiting post 13 is slidably connected to the inside of the pin 4. The pin 4 is in contact with the locking ball 14.
[0034] Specifically, when inserting the pin 4, the operator pushes the push rod 8. After the push rod 8 is pushed, it will cause the connected conical block 12 to move synchronously. At the same time, the limiting disc 9 integrated with the push rod 8 will slide smoothly inside the limiting groove 11. During this process, the spring 10 is compressed by the limiting disc 9. As the conical block 12 moves, its special shape will cause the limiting post 13 to move accordingly, thereby releasing the limiting state of the locking ball 14. At this time, the pin 4 can be inserted smoothly. After the pin 4 is inserted into place, the operator releases the push rod 8, and the spring 10 will quickly rebound, causing the limiting post 13 to quickly return to its original position. During the return process of the limiting post 13, it will push the locking ball 14, so that it accurately slides into the pre-set annular groove 15 on the pin 4, thereby effectively limiting the pin 4 and preventing it from sliding during use, thus ensuring the stability of the connection structure.
[0035] Working principle: When connecting the track plates 1, the two connecting rings 2 on both sides are aligned, and then the pins 4 are inserted into the connecting rings 2. Then, the adjacent pins 4 are connected by the connecting plate 5. Subsequently, the nut 3 is turned into the outer wall of the screw 6 and fixed by the limiting groove 7 to maintain the connection and increase the redundancy of the connection. Even if one pin 4 becomes loose, the other pin 4 can still maintain a certain connection strength through the connecting ring 2, which improves the stability and reliability of the entire connection structure.
[0036] In addition, when inserting the pin 4, the push rod 8 can be pushed, which drives the conical block 12 to move. At the same time, the limiting disc 9 slides inside the limiting groove 11, compressing the spring 10. Then, the conical block 12 drives the limiting post 13 to move, releasing the limiting of the ball 14, so that the pin 4 can be inserted. After releasing the push rod 8, the spring 10 rebounds, driving the limiting post 13 back to its original position, pushing the ball 14, causing it to slide into the annular groove 15, limiting the pin 4 and preventing it from sliding.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
