Description

Technical Field

[0001] This utility model relates to the field of track plate disassembly and assembly technology, specifically to a track plate that is easy to install. Background Technology

[0002] Track shoes, as the core load-bearing and walking components of the chassis system of construction machinery, are widely used in various construction equipment such as excavators, bulldozers, crawler cranes, and pavers. Their performance directly affects the overall driving stability, working efficiency, and service life of the machine. Because construction machinery operates in complex and harsh conditions such as mud, gravel, and steep slopes for a long time, track shoes need to withstand huge impact loads, friction wear, and corrosion. Therefore, they have become typical wear parts and need to be replaced and maintained regularly to ensure the normal operation of the equipment.

[0003] Traditional track shoes are often connected by bolts or pins. This type of connection requires aligning multiple holes during installation, and tightening and loosening bolts and pins requires special tools, making the operation cumbersome. Especially in field operations, the inconvenience of carrying tools and limited space further reduce assembly efficiency.

[0004] Chinese Patent Announcement No. CN222432449U provides a track plate that is easy to install. This solution involves placing connecting blocks and connecting plates alternately, allowing limiting blocks to be inserted into the inner wall of the housing to limit the connection of the connecting blocks and connecting plates. Simultaneously, by rotating a locking block, the operator places the locking block into the inner wall of the locking groove, allowing the locking block to engage with the inner wall of the locking groove, thereby achieving the installation of the track plate. This solution also solves the problem of equipment requiring a lot of time to install.

[0005] However, the following defects still exist in the specific implementation process: the track plates do not take into account the need for secondary adjustment or wear replacement after assembly, and are not convenient for quick disassembly for adjustment or replacement after installation.

[0006] Based on this, the present invention designs an easy-to-install track plate to solve the above problems. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a track plate that is easy to install.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An easy-to-install track plate includes multiple track plate structures. Each track plate structure has a quick-release structure slidably connected to its inner surface. Each quick-release structure includes a pressure plate. A connecting component is slidably connected to the inner surface of the pressure plate. Two nuts are threaded to the outside of the connecting component. A limit component is fixedly connected inside the connecting component.

[0010] Furthermore, the connecting component includes a connecting seat, with connecting holes on both sides, a connecting pipe fixedly connected to the connecting seat, a trapezoidal block fixedly connected to the inner wall of the connecting seat, a screw fixedly connected to the upper end of the trapezoidal block, and multiple limiting rods fixedly connected to the upper end of the connecting seat.

[0011] Furthermore, the quick-release assembly includes a positioning tube, a guide tube fixedly connected inside the positioning tube, a slide rod slidably connected to the inner surface of the guide tube, a rubber plate fixedly connected to one side of the slide rod, and a pressure block fixedly connected to the other side of the slide rod;

[0012] Furthermore, the limiting component includes a hollow tube, a partition is fixedly connected to the inner cavity of the hollow tube, springs are fixedly connected to both sides of the partition, guide rods are fixedly connected to both sides of the partition, and insert rods are fixedly connected to the ends of the two springs that are far apart from each other.

[0013] Furthermore, the track plate structure includes a track plate body, the upper end of which is provided with a plurality of limiting holes, the lower end of which is provided with a trapezoidal groove, and the upper end of which is provided with a round hole.

[0014] Furthermore, the size of the trapezoidal block matches the size of the trapezoidal groove, and the inner walls of the plurality of limiting holes are slidably connected to the plurality of limiting rods respectively;

[0015] Furthermore, the two positioning tubes are fixedly installed on both sides of the connecting seat at their close ends, and the installation positions of the two positioning tubes are concentric with the connecting holes;

[0016] Furthermore, the hollow tube is fixedly installed on the inner wall of the connecting tube, and the outer surfaces of the two insertion rods are slidably connected to the inner surfaces of the two connecting holes, respectively.

[0017] (1) This solution can achieve rapid and accurate positioning of track plates and connecting components by combining the quick disassembly and assembly structure with the track plate structure, without the need to repeatedly adjust the hole position; the pressure plate and double nuts can be used to achieve firm clamping, which is simple to operate and facilitates the quick connection of track plates, significantly improving the installation speed of track plates.

[0018] (2) This solution uses a connecting component, a quick-release component, and a limiting component.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] In some embodiments, please refer to the appendix to the instruction manual. Figure 1 - Figure 5 An easy-to-install track plate includes multiple track plate structures 1. Each track plate structure 1 has a quick-release structure 2 slidably connected to its inner surface. The quick-release structure 2 includes a pressure plate 21. A connecting component 23 is slidably connected to the inner surface of the pressure plate 21. Two nuts 22 are threaded to the outside of the connecting component 23. A limit component 24 is fixedly connected inside the connecting component 23. Quick-release components 25 are fixedly connected to both sides of the connecting component 23.

[0032] The pressure plate 21 is made of Q235 carbon structural steel, is rectangular in shape, and has a rust-proof surface. When used in conjunction with the nut 22, it applies a downward clamping force to the track plate body 101, ensuring the track plate is securely and reliably installed. The nut 22 is a standard hexagonal nut made of 45# steel. Using two nuts 22 together achieves an anti-loosening effect, preventing the track plate body 101 from loosening due to vibration during operation.

[0033] The connecting component 23 includes a connecting seat 231, with connecting holes 232 on both sides of the connecting seat 231. A connecting pipe 233 is fixedly connected to the connecting seat 231. A trapezoidal block 234 is fixedly connected to the inner wall of the connecting seat 231. A screw 235 is fixedly connected to the upper end of the trapezoidal block 234. Multiple limiting rods 236 are fixedly connected to the upper end of the connecting seat 231.

[0034] The connecting hole 232 is a cylindrical through hole used to accommodate the insertion rod 245 of the limiting component 24; the connecting pipe 233 is a seamless steel pipe, welded and fixed to the connecting seat 231, forming an internal cavity to accommodate the limiting component 24; a trapezoidal block 234 is fixedly connected to the inner wall of the connecting seat 231. The trapezoidal block 234 is made of wear-resistant cast iron, and its size matches the trapezoidal groove 103 of the track plate body 101. The initial positioning of the track plate and the connecting seat 231 can be achieved through the sliding cooperation between the trapezoidal block 234 and the trapezoidal groove 103; A screw 235 is fixedly connected to the upper end of the trapezoidal block 234. The screw 235 is made of high-strength threaded steel and is threaded to the trapezoidal block 234. It is used to pass through the pressure plate 21 and cooperate with the nut 22 to achieve clamping. Multiple limiting rods 236 are fixedly connected to the upper end of the connecting seat 231. The limiting rods 236 are cylindrical steel rods and are welded to the connecting seat 231. Their positions correspond one-to-one with the limiting holes 102 of the track plate body 101. The installation positioning accuracy can be further improved by the sliding cooperation between the limiting rods 236 and the limiting holes 102.

[0035] The quick-release assembly 25 includes positioning tubes 251. The two positioning tubes 251 are fixedly installed on both sides of the connecting seat 231 at their close ends. The installation positions of the two positioning tubes 251 are concentric with the connecting hole 232. A guide tube 252 is fixedly connected inside the positioning tube 251. A slide rod 253 is slidably connected to the inner surface of the guide tube 252. A rubber plate 254 is fixedly connected to one side of the slide rod 253, and a pressure block 255 is fixedly connected to the other side of the slide rod 253.

[0036] Spring 243 is a compression spring made of spring steel, which has good elastic restoring performance and is used to provide outward thrust for insertion rod 245; guide rod 244 is a cylindrical steel rod used to guide the sliding direction of insertion rod 245 and prevent the insertion rod 245 from deviating when it extends or retracts.

[0037] The limiting component 24 includes a hollow tube 241, which is fixedly installed on the inner wall of the connecting tube 233. A partition 242 is fixedly connected to the inner cavity of the hollow tube 241. Springs 243 are fixedly connected to both sides of the partition 242. Guide rods 244 are fixedly connected to both sides of the partition 242. Insert rods 245 are fixedly connected to the ends of the two springs 243 that are far apart from each other. The outer surfaces of the two insert rods 245 are slidably connected to the inner surfaces of the two connecting holes 232, and the inner surfaces of the two insert rods 245 are slidably connected to the outer surfaces of the two guide rods 244.

[0038] In this embodiment of the utility model, two nuts 22 are screwed onto the screw 235 in sequence. By tightening the nuts 22, the pressure plate 21 applies a downward pressing force to the track plate body 101, thereby firmly fixing the track plate structure 1 onto the connecting assembly 23. Two nuts 22 can be used to prevent loosening.

[0039] After fixing the track plate body 101 to the connecting seat 231, multiple connecting seats 231 can be connected. The front end of the first connecting seat 231 is inserted into the rear end of the second connecting seat 231. At this time, the two insert rods 245 in the first connecting seat 231 will be squeezed by the inner wall of the second connecting seat 231, slide along the guide rod 244 into the hollow tube 241 and squeeze the spring 243. When the connecting seat 231 is pushed into place, the insert rods 245 will be aligned with the positioning holes on the second connecting seat 231. At this time, the spring 243 pushes the insert rods 245 out of the connecting hole 232 and into the positioning hole under the action of elasticity, realizing the limiting and fixing of the two connecting seats 231. In this way, the connection of multiple connecting seats 231 is completed in sequence, thereby realizing the assembly of multiple track plate bodies 101.

[0040] When the track plate body 101 is severely worn and needs to be replaced, unscrew the two nuts 22 on the screw 235 and remove the pressure plate 21 to quickly remove the track plate body 101 for quick replacement. When the connecting component 23 is severely worn and needs to be replaced, press the pressure block 255 of the quick-release component 25 by hand. The pressure block 255 drives the slide rod 253 to slide along the guide tube 252 toward the connecting seat 231. The rubber plate 254 at one end of the slide rod 253 contacts the insertion rod 245 of the limiting component 24 and pushes the insertion rod 245 to compress the spring 243, so that the insertion rod 245 exits from the positioning hole of the external mounting structure and retracts into the connecting hole 232. At this time, the two adjacent connecting components 23 can be separated. Then, the severely worn connecting component 23 can be removed in the same way for easy replacement.

[0041] In some embodiments, such as Figure 1 and Figure 6 As shown, in a preferred embodiment of the present invention, the track plate structure 1 includes a track plate body 101. The track plate body 101 has a plurality of limiting holes 102 at its upper end. The inner walls of the plurality of limiting holes 102 are slidably connected to a plurality of limiting rods 236. The track plate body 101 has a trapezoidal groove 103 at its lower end. The size of the trapezoidal block 234 matches the size of the trapezoidal groove 103. The track plate body 101 has a circular hole 104 at its upper end.

[0042] The track plate body 101 is made of high-strength wear-resistant alloy steel and is treated with an overall heat treatment process, resulting in high hardness and internal toughness, and good wear and impact resistance. The limiting hole 102 is a cylindrical through hole used to cooperate with the limiting component of the quick-release structure 2 to achieve precise positioning during track plate installation and prevent lateral displacement during use. The diameter of the round hole 104 is matched with the diameter of the screw 235 in the connecting assembly 23, providing a passage for the screw 235 to pass through.

[0043] In this embodiment of the utility model, the trapezoidal groove 103 of the track plate structure 1 is aligned with the trapezoidal block 234 of the connecting component 23, and the track plate body 101 is pushed along the length direction of the trapezoidal block 234 so that the trapezoidal block 234 is completely embedded in the trapezoidal groove 103. At the same time, it is ensured that the multiple limiting rods 236 at the upper end of the connecting seat 231 are respectively inserted into the multiple limiting holes 102 of the track plate body 101. Through the cooperation between the trapezoidal block 234 and the trapezoidal groove 103 and the cooperation between the limiting rods 236 and the limiting holes 102, the track plate structure 1 and the connecting component 23 are accurately positioned to prevent offset during installation. At this time, the screw 235 located above the trapezoidal block 234 will extend out from the round hole 104.

[0044] Working principle:

[0045] When the track plate needs to be installed, first align the trapezoidal groove 103 of the track plate structure 1 with the trapezoidal block 234 of the connecting component 23, and push the track plate body 101 along the length of the trapezoidal block 234 so that the trapezoidal block 234 is fully embedded in the trapezoidal groove 103. At the same time, ensure that the multiple limiting rods 236 at the upper end of the connecting seat 231 are respectively inserted into the multiple limiting holes 102 of the track plate body 101. Through the cooperation between the trapezoidal block 234 and the trapezoidal groove 103 and the cooperation between the limiting rods 236 and the limiting holes 102, the track plate structure 1 and the connecting component 23 are accurately positioned to prevent offset during installation. At this time, the screw 235 located above the trapezoidal block 234 will extend out from the round hole 104.

[0046] After positioning, the pressure plate 21 is pressed down to make it fit against the upper surface of the track plate body 101. Then, two nuts 22 are screwed onto the screw 235 in sequence. By tightening the nuts 22, the pressure plate 21 applies a downward pressing force to the track plate body 101, thereby firmly fixing the track plate structure 1 to the connecting assembly 23. Two nuts 22 can be used to prevent loosening.

[0047] After fixing the track plate body 101 to the connecting seat 231, multiple connecting seats 231 can be connected. The front end of the first connecting seat 231 is inserted into the rear end of the second connecting seat 231. At this time, the two insert rods 245 in the first connecting seat 231 will be squeezed by the inner wall of the second connecting seat 231, slide along the guide rod 244 into the hollow tube 241 and squeeze the spring 243. When the connecting seat 231 is pushed into place, the insert rods 245 will be aligned with the positioning holes on the second connecting seat 231. At this time, the spring 243 pushes the insert rods 245 out of the connecting hole 232 and into the positioning hole under the action of elasticity, realizing the limiting and fixing of the two connecting seats 231. In this way, the connection of multiple connecting seats 231 is completed in sequence, thereby realizing the assembly of multiple track plate bodies 101.

[0048] When the track plate body 101 is severely worn and needs to be replaced, unscrew the two nuts 22 on the screw 235 and remove the pressure plate 21 to quickly remove the track plate body 101 for quick replacement. When the connecting component 23 is severely worn and needs to be replaced, press the pressure block 255 of the quick-release component 25 by hand. The pressure block 255 drives the slide rod 253 to slide along the guide tube 252 toward the connecting seat 231. The rubber plate 254 at one end of the slide rod 253 contacts the insertion rod 245 of the limiting component 24 and pushes the insertion rod 245 to compress the spring 243, so that the insertion rod 245 exits from the positioning hole of the external mounting structure and retracts into the connecting hole 232. At this time, the two adjacent connecting components 23 can be separated. Then, the severely worn connecting component 23 can be removed in the same way for easy replacement.
