Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to track plate assemblies, track devices, chassis, and operating machinery. Background Technology

[0002] As an important component of the walking mechanism of tracked work machinery, the track not only bears the entire weight of the work machinery, but also has to operate under complex and ever-changing working conditions. This requires that the structure of the track itself can ensure stability and service life.

[0003] Traditional tracks use bolts to connect the track shoes and track links. This design often results in problems such as loose bolts during actual use, leading to poor reliability and severely impacting operational efficiency. Furthermore, current track shoes often lack sufficient traction, making them prone to slipping on wet, soft, icy, or sloping surfaces requiring climbing. Summary of the Invention

[0016] In one alternative embodiment, the mounting base is integrally formed with the track plate body and protrudes from the second plate surface of the track plate body.

[0017] Beneficial effect: The fixing seat can be integrally molded when molding the track plate body, eliminating the need for additional fixing seats and making installation convenient.

[0018] In one alternative embodiment, the grip stake body is configured as a cone, and the connecting portion is located at the large end of the cone.

[0019] Beneficial effects: The cone-shaped grip spikes provide better traction, and the pointed end of the cone faces the ground, allowing for quick insertion and preventing slippage.

[0020] In one optional embodiment, the second surface of the track plate body is provided with longitudinal ribs extending along its length direction and oblique ribs connected to the longitudinal ribs and arranged at an angle, the oblique ribs being arranged in pairs, each pair of oblique ribs being arranged at an angle.

[0021] Beneficial effects: The ribbed structure not only increases the structural strength of the track plates, enabling them to withstand stronger torsional and shear forces, but also increases the track plates' grip and prevents slippage.

[0022] In one optional embodiment, the grip studs are disposed within the area enclosed by the paired diagonal ribs and longitudinal ribs on the track plate body;

[0023] The track plate body is provided with a mud discharge port in the area between the left and right track plates.

[0024] Beneficial effect: The ground anchors avoid the ribs to ensure the integrity of the rib structure.

[0025] In one optional embodiment, both the left and right chain plates include a first chain plate portion and a second chain plate portion located on the first plate surface of the track plate body. The first chain plate portion and the second chain plate portion are both strip-shaped and partially intersect each other. A pair of first chain plate portions are provided with pin holes on one side of the intersecting portion, and a pair of second chain plate portions are provided with pin sleeve holes on the other side of the intersecting portion.

[0026] Beneficial effects: Both the left and right chain plates have a "Z" shaped structure, which is simple and facilitates the setting of pin holes and pin sleeve holes.

[0027] In one optional embodiment, at least one side of the second chain plate portion is provided with a groove, the length of the groove extends along the length direction of the second chain plate portion, the width of the groove extends from the end of the second chain plate portion connected to the track plate body to the end away from the track plate body, and the width of the groove is less than the height of the second chain plate portion, so as to form a support protrusion at the end of the second chain plate portion away from the track plate body, the support protrusion being used to support the track roller;

[0028] The groove is divided into a first groove and a second groove by a partition. The first groove corresponds to the intersecting part, and the second groove corresponds to the pin hole. A pin fixing plate is fixed at the opening of the second groove, and an openable mud removal plate is provided at the opening of the first groove.

[0029] Beneficial effects: By incorporating an openable mud-removing plate, when there is a significant amount of mud or dirt on the opposite sides of the track shoe body located on the track link, the mud-removing plate can be opened to scrape away the mud or dirt on the first surface of the track shoe body, preventing mud or dirt from corroding the track and causing seal failure or other malfunctions. After the mud or dirt is removed, the mud-removing plate can be manually closed, making it convenient to use. The pin fixing plate effectively secures the axial end of the pin, preventing pin slippage.

[0030] In one optional embodiment, one side of the sludge removal plate is hinged to the side wall of the first groove, and the other side of the sludge removal plate is provided with a latch. The side wall of the first groove is provided with a lock body, and the latch is engaged with the lock body. The first groove is provided with a sensor switch, a pre-compressed elastic element, and at least one telescopic rod. When the sensor switch senses that the sludge has submerged the sludge removal plate, it sends a signal to the control center. After receiving the signal, the control center sends an opening signal to the latch. When the latch opens, the elastic element and the telescopic rod push out the sludge removal plate together.

[0031] Beneficial effects: It can automatically remove dirt, mud or grime from the tracks, preventing dirt or grime from corroding the tracks.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] In existing tracks, the track links are assembled and then bolted to the track plates. This requires drilling threaded holes in both the track links and track plates before tightening the bolts, resulting in low installation efficiency. Furthermore, the track links are prone to cracking due to the constant stress from the bolts, and this design often leads to bolt loosening and other malfunctions during actual use. Additionally, while track plates typically have anti-slip ribs that meet requirements on regular roads, slippage is common on wet, soft surfaces, ice, or steep slopes.

[0054] To address the aforementioned technical problems, this invention provides a track pad assembly. The following is in conjunction with... Figures 1 to 7 The following describes embodiments of the present invention.

[0055] On the one hand, such as Figure 1 and Figure 4 As shown, an embodiment of the present invention provides a track plate assembly, which mainly includes a track plate body 1, a track link 2, and... Figure 7 The shown is grip spike 13.

[0056] Specifically, the track link 2 includes a left track plate 21 and a right track plate 22 arranged opposite to each other. The left track plate 21 and the right track plate 22 are integrally formed on the first plate surface 11 of the track plate body 1. In other words, the track link 2 and the track plate form an integral structure during manufacturing.

[0057] Specifically, the traction spikes 13 are detachably mounted on the track plate body 1 and protrude from the second plate surface 12 of the track plate body 1, wherein the second plate surface 12 is disposed opposite to the first plate surface 11.

[0058] It should be noted that the first plate surface 11 and the second plate surface 12 are two opposite sides of the track plate body 1. The first plate surface 11 is directly connected to the track link 2, and the second plate surface 12 is the side for contacting the ground.

[0059] The track link 2 of this invention is integrally formed with the track plate body 1, creating a one-piece track plate structure. During manufacturing, the two are fixed together, eliminating the need for separate bolt assembly. This ensures a reliable connection between the track link 2 and the track plate body 1, increasing connection strength and load-bearing capacity, and preventing cracking or breakage of the track link 2. Furthermore, by incorporating detachable traction spikes 13, they can be installed on wet, soft surfaces, ice, or steep slopes to enhance track grip and climbing ability, preventing slippage. During normal operation, the traction spikes 13 can be removed to prevent excessive wear and reduced service life. When long-term use causes the traction spikes 13 to wear down and no longer meet requirements, they can be replaced with traction spikes of the same specification. The operation is simple and convenient, and disassembly is free.

[0060] It is understandable that multiple track links 2 are connected end to end in sequence, and the track plate bodies 1 are located one by one on the outside of the track links 2, forming a ring. The ring-shaped track links 2 and the multiple track plate bodies 1 located on their outside together constitute the track.

[0061] The primary function of tracks is to increase the contact area, reduce pressure on the ground, and allow for smooth movement on the ground. Tracks operate under harsh conditions, requiring sufficient strength and rigidity, good wear resistance, and light weight to reduce metal consumption and alleviate dynamic loads during operation. In this embodiment, the tracks are made of metal materials to meet the necessary strength and rigidity requirements, such as steel or alloys.

[0062] Specifically, the length direction of the track plate body 1 is oriented towards the width direction of the track, the length direction of the track link 2 is along the width direction of the track plate body 1, i.e. the length direction of the track, and the left track plate 21 and the right track plate 22 are symmetrically arranged about the axis of the width direction of the track plate body 1.

[0063] In one specific embodiment, the left track plate 21 and the right track plate 22 are integrally formed with the track plate body 1 by casting or forging. Casting or forging is a simple and reliable forming method. Compared with the method of connecting the track link 2 and the track plate body 1 by bolts, the assembly efficiency is high, and the track link 2 and the track plate body 1 have high strength after forming.

[0064] In a specific embodiment, such as Figure 7 As shown, the grip spike 13 includes a grip spike body 131 and a connecting portion 132 extending axially along the grip spike body 131. The connecting portion 132 is provided with external threads, such as... Figure 3As shown, the track plate body 1 has an internally threaded hole 15 at the position for installing the traction spike 13. The traction spike 13 is connected to the internally threaded hole 15 via a connecting part 132. When it is necessary to install the traction spike 13, simply align the connecting part 132 of the traction spike 13 with the threaded hole 15 and tighten it, with the traction spike body 131 facing the second plate surface 12 of the track plate body 1. This is especially useful for increasing the track plate's traction, particularly when climbing slopes or under special working conditions. During normal operation, the connecting part 132 of the traction spike 13 can be directly removed from the threaded hole 15 to prevent excessive wear. Therefore, the traction spike 13 and the track plate body 1 are reliably connected and easy to disassemble via a threaded connection.

[0065] In another feasible embodiment, such as Figure 7 As shown, the traction spike 13 includes a traction spike body 131 and a connecting portion 132 extending axially along the traction spike body 131. The connecting portion 132 has external threads. A fixing seat 14 is provided at the position on the track plate body 1 for mounting the traction spike 13. The fixing seat 14 has an internal threaded hole 15 axially. The traction spike 13 is threadedly connected to the internal threaded hole 15 through the connecting portion 132. Compared with the previous embodiment where the threaded hole 15 is directly formed on the track plate body 1, this embodiment forms the fixing seat 14 on the track plate body 1 and then provides the threaded hole 15 on the fixing seat 14, which helps to ensure the structural integrity of the track plate body 1. By providing the fixing seat 14, the traction spike 13 and the fixing seat 14 are connected by threads, which is reliable and easy to disassemble.

[0066] In a specific working condition, for example, a tracked excavator equipped with the tracks of this embodiment needs to traverse a steep slope to reach another location for work. When traveling on normal roads, it is not necessary to install traction spikes 13; the anti-skid ribs are sufficient for anti-skid requirements. Before traversing the steep slope, spare traction spikes 13 can be removed and tightened into the threaded holes 15 on each track plate body 1. Typically, each track plate body 1 has 2-4 threaded holes 15. After tightening traction spikes 13 into each threaded hole 15, the tracked excavator can be driven across the steep slope. Because the traction spikes can penetrate the ground, the adhesion to the ground is sufficient to support the tracked excavator across the steep slope. When the excavator has traversed the steep slope and reached the normal road surface, it can be stopped and the traction spikes 13 can be removed. Since the traction spikes 13 are threadedly connected to the threaded holes 15, removal and installation are relatively convenient.

[0067] In one specific embodiment, the fixing seat 14 is integrally formed with the track plate body 1 and protrudes from the second plate surface 12 of the track plate body 1. The fixing seat 14 can be integrally formed when forming the track plate body 1, eliminating the need for an additional fixing seat 14, which is convenient.

[0068] In one specific embodiment, the grip spike body 131 is configured as a cone, such as a cylindrical cone, with the connecting portion 132 located at the large end of the cone and the small end of the cone facing the ground. The grip spike 13 with the cone structure has stronger grip, and the tip of the cone facing the ground can quickly insert into the ground when the track is moving, improving the track's adhesion on wet and slippery surfaces, steep slopes and other harsh working conditions, and preventing slippage.

[0069] like Figure 3 As shown, in a specific embodiment, the second surface 12 of the track plate body 1 is provided with longitudinal ribs 16 extending along its length and oblique ribs 17 connected to the longitudinal ribs 16 and arranged at an angle. The oblique ribs 17 are arranged in pairs, and each pair of oblique ribs 17 is arranged at an angle. That is, the oblique ribs 17 and the longitudinal ribs 16, as well as the pairs of oblique ribs 17, are arranged at an angle to each other. Taking an included angle of 60 degrees as an example, a pair of oblique ribs 17 and the longitudinal ribs 16 form a "K" shape. If longitudinal ribs 16 are provided on both sides of the track plate body 1, and each pair of oblique ribs 17 is connected to the longitudinal ribs 16 on both sides respectively, triangular ribs can be formed. By providing a rib structure on the second surface 12 of the track plate body 1, not only is the structural strength of the track plate increased, which can withstand stronger torsional and shear forces, but the grip of the track plate is also increased, helping to prevent slippage.

[0070] In one specific embodiment, the grip spikes 13 are located within the area enclosed by paired diagonal ribs 17 and longitudinal ribs 16 on the track plate body 1. A mud discharge port 18 is provided on the track plate body 1 between the left track plate 21 and the right track plate 22. During track movement, mud and gravel are more easily discharged under centrifugal force and gravity, enhancing the track's mud removal and waste disposal capabilities. The mud discharge port 18 can be shaped as an isosceles trapezoid to accommodate the discharge of various shapes of gravel. The four corners of the isosceles trapezoid are rounded to reduce stress concentration. The grip spikes 13 are positioned to avoid the ribs, ensuring the integrity of the rib structure.

[0071] Furthermore, such as Figure 2As shown, both the left track plate 21 and the right track plate 22 include a first track plate portion 23 and a second track plate portion 24 located on the first plate surface 11 of the track plate body 1. That is, the first track plate portion 23 and the second track plate portion 24 are at the same height relative to the first plate surface 11. The first track plate portion 23 and the second track plate portion 24 are both strip-shaped and partially intersect, that is, partially overlap. The non-overlapping portions form two extensions in opposite directions. A pair of first track plate portions 23 of the left track plate 21 and the right track plate 22 are provided with pin holes 25 on one side of the intersecting portion. The two adjacent track links 2 are connected by passing pins through the pin holes 25. A pair of second track plate portions 24 are provided with pin sleeve holes 26 on the other side of the intersecting portion. The pin sleeve holes 26 are used to install pin sleeves, which are used to protect the two ends of the pin. Understandably, a pair of first chain plate portions 23 of one link 2 are connected to a second chain plate portion 24 of another link 2 by a pin and a pin sleeve is provided. The pin passes through a pin hole 25, and the pin sleeve is located in a pin sleeve hole 26. Both the left chain plate 21 and the right chain plate 22 have a "Z" shaped structure and flat sides, which is simple in structure and facilitates the setting of the pin hole 25 and the pin sleeve hole 26.

[0072] In a specific embodiment, such as Figure 5 and Figure 6 As shown, at least one second track plate portion 24 has a groove on its side. Grooves can be provided on the sides of both second track plate portions 24, or only on the side of one second track plate portion 24. The length of the groove extends along the length direction of the second track plate portion 24. It can be understood that the length direction of the second track plate portion 24 is the width direction of the track plate body 1. The width of the groove extends from the end of the second track plate portion 24 connected to the track plate body 1 to the end away from the track plate body 1, and the width of the groove is less than the height of the second track plate portion 24, so as to form a support protrusion 29 at the end of the second track plate portion 24 away from the track plate body 1. The support protrusion 29 is used to support the track roller.

[0073] Furthermore, the groove is divided into a first groove 27 and a second groove 28 by a partition. The first groove 27 corresponds to the intersecting part, and the second groove 28 corresponds to the pin sleeve hole 26. A pin fixing plate 281 is fixed at the opening of the second groove 28. By setting the pin fixing plate 281, the axial end of the pin can be fixed, preventing pin slippage, extending the service life of the track, and reducing the failure rate. An openable mud removal plate 274 is provided at the opening of the first groove 27. By setting the openable mud removal plate 274, when there is a lot of mud or dirt on the opposite sides of the track plate body 1 located on the track link 2, the mud removal plate 274 can be opened to scrape off the mud or dirt on the first plate surface 11 of the track plate body 1, preventing the mud or dirt from corroding the track and causing seal failure and other malfunctions. After the mud or dirt is removed, the mud removal plate 274 can be manually closed for convenient use.

[0074] In one specific embodiment, one side of the mud removal plate 274 is hinged to the side wall of the first groove 27, and the other side of the mud removal plate 274 is provided with a latch. The side wall of the first groove 27 is provided with a lock body, and the latch is engaged with the lock body. The first groove 27 is provided with a sensor switch 271, a pre-compressed elastic element 272, and at least one telescopic rod 273. Of course, a guide rod can be provided at the installation location of the elastic element 272 to guide the elastic element 272. Specifically, the elastic element 272 can be a compression spring, which is sleeved on the guide rod. The guide rod is fixed to the bottom wall of the first groove 27, and one end of the compression spring is sleeved on the guide rod and fixedly connected to the bottom wall of the first groove 27. When the mud removal plate 274 is closed, the elastic element 272 is in a compressed state to provide a reverse thrust when the mud removal plate 274 is opened.

[0075] When the inductive switch 271 detects that the sludge has exceeded the mud removal plate 274, it sends a signal to the control center. The control center can be the control center for the entire machine and can be located in the driver's cab; the specific installation location is not limited here. Upon receiving the signal, the control center sends an open signal to the latch. Simultaneously, the elastic element 272 uses its elastic force to push the mud removal plate 274, and the telescopic rod 273 extends to push the mud removal plate 274 further. Through the combined action of the elastic element 272 and the telescopic rod 273, the mud removal plate 274 can be pushed out. This achieves automatic decontamination and removal of mud or dirt from the tracks, preventing sludge or dirt from corroding the tracks. After the mud or dirt is removed, the mud removal plate 274 can be manually closed, causing the latch to engage with the lock body.

[0076] It should be noted that one end of the telescopic rod 273 can be hinged to the bottom wall of the first groove 27, and the other end can be hinged to the side wall of the mud removal plate 274. The specific configuration of the telescopic rod 273 is not specifically limited here, as long as it can push the mud removal plate 274.

[0077] In another specific embodiment, one side of the mud removal plate 274 is hinged to the opening sidewall of the first groove 27, and the other side of the mud removal plate 274 is provided with a buckle. The opening sidewall of the first groove 27 is provided with a slot, and the buckle and the slot are engaged. When there is a lot of mud or dirt on the opposite sides of the track plate body 1 located on the track link 2, the mud removal plate 274 can be manually opened to remove the mud or dirt. The structure of manually opening the mud removal plate 274 is simpler, eliminating the need for components such as the induction switch 271, and thus reducing costs.

[0078] On the other hand, embodiments of the present invention also provide a tracked device, comprising:

[0079] Multiple track plate assemblies are connected end to end to form a track. Adjacent track links 2 are connected by pins. Multiple track links 2 are connected end to end to form a track. Track plate bodies 1 are correspondingly located on the outside of track links 2.

[0080] The support roller has a shoulder located between the left chain plate 21 and the right chain plate 22.

[0081] In related technologies, tracked devices include a traveling frame, track links, and tracks. Support rollers are located at the bottom of the traveling frame, and track carrier rollers are located at the top. Drive wheels and sprockets are located at the front and rear ends of the traveling frame, respectively. The track links surround the outside of the support rollers, drive wheels, sprockets, and track carrier rollers, and the track links can be tensioned on the traveling frame by adjusting the track carrier rollers. By using the aforementioned track plate assembly, the tracked device has a high degree of integration, good grip, prevents slippage, and can automatically or manually remove mud from the track plates.

[0082] Furthermore, the present invention also provides a chassis, comprising a chassis body and two aforementioned track devices, the two track devices being respectively disposed on opposite sides of the chassis body. Since the chassis includes track devices, it possesses all the advantages of track devices, which will not be elaborated further here.
