Description

Technical Field

[0001] This application belongs to the technical field of construction machinery, and particularly relates to a crawler protection module, a crawler chassis assembly, and a construction machinery. Background Art

[0002] The crawler-type walking chassis realizes power transmission through the meshing of the driving wheel teeth and the crawler chain. When the driving wheel rotates, the crawler is wound backward, and the whole machine is pushed forward by the reaction force between the grounded crawler and the ground. However, under complex working conditions, the crawler is prone to lateral displacement, resulting in the risk of derailment.

[0003] The prior art mostly adopts the structure of welding rigid protection side plates, and physically limits both sides of the crawler track through side baffles. However, this solution has obvious defects: First, the protection side plates are in direct rigid collision with the crawler for a long time, which is prone to cause stress concentration, resulting in cracking of the welding area of the protection side plates and a decrease in structural strength, affecting safety and stability; Second, the rigid friction will accelerate the surface wear of the crawler track, induce oxidation corrosion of the base material after destroying the rust-proof layer, and shorten the service life of the transmission system. In addition, the vibration generated by frequent collisions will also interfere with the smooth operation of the equipment and increase the additional load on the driving components.

[0006] An elastic buffer assembly;

[0007] A guard rail beam frame, which is used to be installed on the crawler frame. At least one limit mounting plate is provided on both sides of the guard rail beam frame in the width direction of the crawler track, and each limit mounting plate is provided with the elastic buffer assembly; and

[0008] A collision assembly, which is arranged on the elastic buffer assembly and is used to be arranged corresponding to the side wall of the crawler track;

[0009] Wherein, when the collision assembly collides with the side wall of the crawler track, the elastic buffer assembly is used to drive the collision assembly to perform elastic reset.

[0010] As a further improvement of the above technical solution:

[0011] In some embodiments, the elastic buffer assembly includes at least one elastic reset module, and the elastic reset module is disposed on the corresponding limit mounting plate:

[0012] The collision assembly includes a connecting plate and a collision module. One end of the connecting plate is connected to the elastic reset module, and the other end is connected to the collision module.

[0013] In some embodiments, the collision module includes:

[0014] A side collision bar, connected to the elastic buffer assembly and located below the elastic buffer assembly; and

[0015] An anti-collision protection member, disposed on the collision side of the side collision bar.

[0016] In some embodiments, the anti-collision protection member is an anti-collision pulley;

[0017] Wherein, a plurality of the anti-collision pulleys are disposed along the length direction of the collision side of the side collision bar, and each anti-collision pulley is used for rolling contact with the crawler track;

[0018] Alternatively, the anti-collision protection member is an anti-collision ball, a plastic part or a rubber part.

[0019] In some embodiments, the side collision bar and the bottom end of the limit mounting plate are in sliding fit or rolling fit.

[0020] In some embodiments, the elastic buffer assembly includes at least one elastic reset module, and the elastic reset module is disposed on the corresponding limit mounting plate;

[0021] The collision assembly includes at least one collision module, and the collision module is disposed on the side of the elastic reset module facing the crawler track.

[0022] In some embodiments, the elastic reset module includes:

[0023] A guide shaft, one end of which is connected to the collision assembly, and the other end passes through the limit mounting plate and is in sliding fit with the limit mounting plate;

[0024] A first elastic reset member, sleeved on the guide shaft and located on one side of the limit mounting plate; and

[0025] A first connection end cap, sleeved on the guide shaft and between the first elastic reset member and the limit mounting plate. One side of the first connection end cap is connected to the first elastic reset member, and the other side is connected to the limit mounting plate.

[0026] In some embodiments, the elastic reset module further includes:

[0027] A second elastic reset member, sleeved on the guiding shaft and located on the other side of the limit mounting plate; and

[0028] A second connection end cover, sleeved on the guiding shaft and located between the second elastic reset member and the limit mounting plate, one side of the second connection end cover is connected to the second elastic reset member, and the other side is connected to the limit mounting plate.

[0031] Compared with the prior art, a crawler protection module, a crawler chassis assembly and a working machine provided by the present application at least include the following technical effects:

[0032] The crawler protection module provided by the present application is installed on the crawler frame through the guard rail beam frame, and then the two sides of the crawler track are limited by the elastic buffer components and the collision components located on both sides in the width direction of the crawler track. In this way, when the crawler undergoes a lateral offset, the crawler track will collide with the collision components on the side. In the case of a collision between the collision components and the side wall of the crawler track, the collision impact will be transmitted to the elastic buffer components. The elastic buffer components absorb the collision energy through elastic deformation to achieve buffering. At the same time, the elastic potential energy generated by the elastic deformation after the collision of the elastic buffer components drives the collision components to perform elastic reset, thereby driving the crawler to return to the initial position, that is, the normal working position.

[0033] In this way, on the one hand, the crawler protection module provided by the present application provides buffering and energy absorption for the collision of the crawler track, realizes flexible collision, and is more reliable in structure and has improved safety and stability compared with the traditional rigid collision; on the other hand, by using buffer limiting, it can effectively avoid the direct rigid collision between the crawler track and the collision components, thereby reducing the wear after the collision and extending the service life of the crawler and the crawler protection module; on the third hand, by using buffer energy absorption, it can effectively avoid the vibration generated by the collision, ensure the stable operation of the equipment (working machine), and reduce the additional load on the driving components.

[0050] The following details the specific implementation manner of the present application in conjunction with the accompanying drawings. It should be understood that the specific implementation manner described herein is only for explaining and illustrating the present application and is not used to limit the present application.

[0051] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0052] It should be noted that in order to solve the problem of limiting the lateral offset of the crawler under complex working conditions in the prior art, a solution is to physically limit the crawler by welding side baffles on both sides of the crawler frame. Through practical verification, this solution has significant technical defects: First, the rigid contact interface lacks a buffering mechanism, and stress concentration is likely to occur in the protective side plate during long-term high-frequency collisions, leading to safety hazards such as cracking at the welding part and attenuation of structural strength; Second, the direct friction between metals accelerates the wear of the protective layer on the surface of the crawler track. After the base material is exposed, oxidation and rusting are caused, resulting in a decrease in the meshing accuracy between the crawler links and the driving wheel teeth, and ultimately causing a reduction in transmission efficiency and a shortening of service life. In addition, the abnormal vibration generated by the rigid collision will also affect the smooth operation of the whole machine and increase the additional load on the drive system. Thus, the existing rigid limit design has significant technical bottlenecks in terms of durability and reliability.

[0053] It should be noted that Figure 1 The direction indicated by arrow V in the figure is the traveling direction or the length direction of the crawler body 300; Figure 4 The direction indicated by arrow W in the figure is the width direction of the crawler track.

[0054] Embodiment 1

[0055] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4, To solve the above technical problems, this embodiment provides a crawler protection module 100. The crawler protection module 100 is applied to a crawler chassis assembly, which includes a crawler frame 200 and a crawler body 300 disposed around the crawler frame 200. A crawler track 310 is provided on one side of the crawler body 300 facing the crawler frame 200.

[0056] The crawler protection module 100 provided in this embodiment includes a guard rail beam frame 110, an elastic buffer assembly 120, and a collision assembly 130. The guard rail beam frame 110 is used to be installed on the crawler frame 200, for example, connected by welding or bolts and screws. At least one limit mounting plate 111 is provided on both sides of the guard rail beam frame 110 in the width direction of the crawler track, and an elastic buffer assembly 120 is provided on each limit mounting plate 111.

[0057] The guard rail beam frame 110 is a frame structure. Among them, a reverse "U" - shaped avoidance notch is formed in the middle of the guard rail beam frame 110 to avoid the crawler track 310. The limit mounting plates 111 are located on both sides of the reverse "U" - shaped avoidance notch. Reinforcing rib plates are further welded on both sides of the limit mounting plates 111.

[0058] Please refer to Figure 3 and Figure 4 , The collision assembly 130 is disposed on the elastic buffer assembly 120 and is arranged corresponding to the side wall of the crawler track 310. In other words, collision assemblies 130 are arranged corresponding to both sides of the side wall of the crawler track 310.

[0059] Among them, the crawler body 300 does not contact the collision assemblies 130 on both sides during normal operation. When the crawler body 300 undergoes a lateral offset (movement in the width direction of the crawler track), the side wall of the crawler track 310 will collide with the collision assembly 130 on the offset side. After the collision, the elastic buffer assembly 120 is used to drive the collision assembly 130 to perform elastic reset, so as to perform lateral limit on the crawler track 310 (i.e., limit in the width direction of the crawler track).

[0060] In some embodiments, one collision assembly 130 can be respectively provided on the elastic buffer assemblies 120 on the same side. In other words, each elastic buffer assembly 120 corresponds to one collision assembly 130.

[0061] In this embodiment, the elastic buffer assemblies 120 on the same side share one collision assembly 130. In other words, one collision assembly 130 can be connected to at least two elastic buffer assemblies 120 on the same side, and its elastic buffer capacity is stronger and the effect is more obvious compared with the one - to - one method.

[0062] Please refer to Figure 3 and Figure 4, It can be understood that the crawler protection module 100 provided in this embodiment is installed on the crawler frame 200 through the guard rail beam frame 110, and then the two sides of the crawler track 310 are limited by the elastic buffer components 120 and the collision components 130 located on both sides in the width direction of the crawler track. In this way, when the crawler undergoes a lateral offset, the crawler track 310 will collide with the collision component 130 on the side. Among them, when the collision component 130 collides with the side wall of the crawler track 310, the collision impact will be transmitted to the elastic buffer component 120. The elastic buffer component 120 absorbs the collision energy through elastic deformation to achieve buffering. At the same time, the elastic buffer component 120 drives the collision component 130 to perform elastic reset through the elastic potential energy generated after elastic deformation after the collision, so as to drive the crawler to return to the initial position, that is, the normal working position.

[0063] In this way, on the one hand, the crawler protection module 100 provided in this embodiment provides buffering and energy absorption for the collision of the crawler track 310, realizing flexible collision. Compared with the traditional rigid collision, the structure is more reliable and the safety and stability are improved; on the other hand, by using buffer limiting, the direct rigid collision between the crawler track 310 and the collision component 130 can be effectively avoided, thereby reducing the wear after the collision and extending the service life of the crawler and the crawler protection module 100; on the other hand, by using buffer energy absorption, the vibration generated by the collision can be effectively avoided, ensuring the stable operation of the equipment (working machinery) and reducing the additional load on the driving components.

[0064] To more clearly describe the technical solution of the present application, the crawler protection module 100 provided in this embodiment is described in detail below, as follows:

[0065] Please refer to Figure 3 , Figure 4 and Figure 5 , the above-mentioned elastic buffer component 120 includes at least one elastic reset module 121, and all the elastic reset modules 121 are arranged on the corresponding limit mounting plate 111. The collision component 130 includes a connecting plate 132 and at least one collision module 131. One end of the connecting plate 132 is connected to the elastic reset module 121, and the other end is connected to the collision module 131. The elastic reset module 121 provides elastic buffering for the collision component 130.

[0066] In this way, when the collision module 131 is laterally impacted, it will be linked to the elastic reset module 121 through the connecting plate 132. The elastic reset module 121 absorbs energy and buffers through elastic deformation, thereby avoiding rigid impact. At the same time, the elastic reset module 121 drives the connecting plate 132 and the collision module 131 to reset through the elastic potential energy generated by itself, so as to limit the crawler track 310.

[0067] It can be understood that the number of elastic reset modules 121 can be set to 2, 3, 4 or other numbers. Specifically, the number of elastic reset modules 121 can be selected according to the size of the crawler to ensure the limiting effect of the crawler track 310.

[0068] Please refer to Figure 6 together. In this embodiment, a scheme with 2 elastic reset modules 121 is illustrated. Thus, taking 2 elastic reset modules 121 as an example, the 2 elastic reset modules 121 can be arranged in the vertical direction (of course, they can also be arranged in the horizontal direction). It should be noted that in this embodiment, the vertical direction is adopted. Define the distance from the impact point to the root of the limit mounting plate 111 as X, the distance from the lower elastic reset module 121 to the top of the guard rail beam frame 110 as X1, the distance from the upper elastic reset module 121 to the top of the guard rail beam frame 110 as X2, the collision force generated by the crawler track 310 as F, and the distance from the acting point of the crawler track 310 and the crawler protection module 100 to the impact point as L1. The formed collision moment is M1, M1 = (F - 2×F t )×L1, where F t is the counteracting force provided by a single elastic reset module 121.

[0069] However, when using the rigid limit in the prior art, assuming the collision force is F and remains unchanged, the distance from the root of the rigid limit piece to the impact point is L2, where L2 = X. Thus, the formed collision moment is M2, M2 = F×L2. Since L2 > L1 and F > (F - 2×F t ), the collision moment M2 > M1 generated by the collision. That is to say, the moment generated by the collision of the crawler protection module 100 provided in this embodiment is smaller and the structure is more reliable. It should be understood that the above is only an example and does not limit the protection scope of this application.

[0070] Please refer to Figure 5 and Figure 7 . In some embodiments, the elastic reset module 121 includes a guide shaft 1210, a first elastic reset member 1211 and a first connection end cover 1212. One end of the guide shaft 1210 is connected to the connection plate 132, and the other end passes through the limit mounting plate 111 and is slidably matched with the limit mounting plate 111. Specifically, a shaft hole 1111 can be opened on the limit mounting plate 111, and the guide shaft 1210 can be directly inserted into the shaft hole 1111, or a linear bearing or a bushing can be arranged in the shaft hole 1111 of the limit mounting plate 111 to reduce friction.

[0071] Among them, the first elastic reset member 1211 is sleeved on the guide shaft 1210 and is located on one side of the limit mounting plate 111 (it can be the side close to the connecting plate 132 or the side far from the connecting plate 132); the first connecting end cover 1212 is sleeved on the guide shaft 1210 and is between the first elastic reset member 1211 and the limit mounting plate 111. One side of the first connecting end cover 1212 is connected to the first elastic reset member 1211, and the other side is connected to the limit mounting plate 111.

[0072] In this way, when the collision module 131 is subjected to a collision impact, the connecting plate 132 will drive the guide shaft 1210 to move along its own axial direction. At this time, the guide shaft 1210 will drive the first elastic reset member 1211 to move towards the limit mounting plate 111 (compressing the first elastic reset member 1211) or away from the limit mounting plate 111 (stretching the first elastic reset member 1211).

[0073] Furthermore, the elastic reset module 121 further includes a first guide sleeve 1213. The first guide sleeve 1213 is installed on the guide shaft 1210 by bolts and is at the same end as the first elastic reset member 1211. One end of the first elastic reset member 1211 is connected to the first guide sleeve 1213, and the other end is connected to the first connecting end cover 1212. The first guide sleeve 1213 and the guide shaft 1210 can jointly provide a guiding function for the first elastic reset member 1211 to prevent the first elastic reset member 1211 from shifting out.

[0074] Please refer to Figure 5 and Figure 7 , in this embodiment, elastic reset members (the first elastic reset member 1211 and the second elastic reset member 1214) can be provided on both sides of the limit mounting plate 111. In this way, in this embodiment, the elastic reset module 121 further includes a second elastic reset member 1214 and a second connecting end cover 1215.

[0075] The second elastic reset member 1214 is sleeved on the guide shaft 1210 and is located on the other side of the limit mounting plate 111; the second connecting end cover 1215 is sleeved on the guide shaft 1210 and is between the second elastic reset member 1214 and the limit mounting plate 111. One side of the second connecting end cover 1215 is connected to the second elastic reset member 1214, and the other side is connected to the limit mounting plate 111.

[0076] The elastic reset module 121 further includes a second guide sleeve 1216. The second guide sleeve 1216 is mounted on the guide shaft 1210 by bolts and is located at the same end as the second elastic reset member 1214. One end of the second elastic reset member 1214 is connected to the second guide sleeve 1216, and the other end is connected to the second connection end cover 1215. The second guide sleeve 1216 and the guide shaft 1210 can jointly provide a guiding function for the second elastic reset member 1214 to prevent the second elastic reset member 1214 from shifting out.

[0077] In this way, when the collision module 131 is subjected to a collision impact, the connecting plate 132 will drive the guide shaft 1210 to move along its own axial direction. At this time, the guide shaft 1210 will drive the first elastic reset member 1211 to move in the direction close to the limit mounting plate 111 to compress the first elastic reset member 1211), and the guide shaft 1210 will drive the second elastic reset member 1214 to move in the direction away from the limit mounting plate 111 (stretching the second elastic reset member 1214). The first elastic reset member 1211 and the second elastic reset member 1214 are linked and cooperate to improve the buffering effect and achieve the rapid reset of the collision module 131.

[0078] Optionally, the first elastic reset member 1211 and the second elastic reset member 1214 can be selected from mechanical springs, elastic sheets, torsion springs, gas springs or other materials or structures that can undergo elastic deformation, etc. It should be understood that the above is only an example and does not limit the protection scope of the present application.

[0079] Please refer to Figure 3 、 Figure 5 and Figure 8 As shown in the above, the collision module 131 includes a side collision bar 1310 and an anti-collision protection member 1311. The side collision bar 1310 is connected to the elastic buffer assembly 120 and is located below the elastic buffer assembly 120. Specifically, the side collision bar 1310 is mounted on the connecting plate 132, and the anti-collision protection member 1311 is disposed on the collision side of the side collision bar 1310. The anti-collision protection member 1311 prevents the crawler track 310 and the side collision bar 1310 from rigidly contacting and rubbing.

[0080] Optionally, the anti-collision protection member 1311 is an anti-collision pulley, an anti-collision ball, a plastic part or a rubber part. It should be understood that the above is only an example and does not limit the protection scope of the present application.

[0081] In this embodiment, the anti-collision protection member 1311 can be selected as an anti-collision pulley (as shown in Figure 8 ). Among them, a plurality of anti-collision pulleys are arranged on the collision side of the side collision bar 1310 along its length direction, and the rotation axis of each anti-collision pulley is along the vertical direction ( Figure 8The anti-collision pulley is arranged in the vertical direction of the viewing angle shown, so that when the anti-collision pulley contacts the crawler track 310, it can roll with the crawler track 310 to further reduce the wear on the crawler track 310.

[0082] See also Figure 8 and Figure 9 Furthermore, since the collision assembly 130 will generate a certain amount of displacement after colliding with the crawler track 310, in order to ensure that the collision assembly 130 can smoothly link the elastic buffer assembly 120 when it is displaced, in this embodiment, the collision module 131 and the bottom end of the limiting mounting plate 111 are designed to be slidingly matched or rollingly matched.

[0083] Optionally, a rollable support roller 1110 / support ball is installed at the bottom end of the limit mounting plate 111, and the support roller 1110 / support ball is in rolling cooperation with the side collision bar 1310 in the collision module 131. The rotation axis of the support roller 1110 is perpendicular to the rotation axis of the anti-collision pulley, and the rotation axis of the support roller 1110 is consistent with the travel direction of the crawler track 310.

[0084] See also Figure 1 Furthermore, this embodiment also provides a crawler chassis assembly. The crawler chassis assembly includes a crawler frame 200, a crawler body 300 arranged around the crawler frame 200, and at least one crawler protection module 100 provided according to the above embodiment.

[0085] Furthermore, this embodiment also provides a working machine, such as an agricultural working machine, which includes the crawler chassis assembly provided above.

The crawler protection module 100 is applied to a crawler chassis assembly, which includes a crawler frame 200 and a crawler body 300 arranged around the crawler frame 200. The crawler body 300 is provided with a crawler track 310 on one side facing the crawler frame 200. This embodiment is an improvement made on the technical basis of the above-mentioned embodiment 1, and the difference from the above-mentioned embodiment 1 is as follows:

[0088] In this embodiment, the elastic buffer assembly 120 includes at least one elastic reset module 121, and all the elastic reset modules 121 are arranged on the corresponding limit mounting plate 111; the collision assembly 130 includes at least one collision module 131, and the collision module 131 is directly arranged on the side of the elastic reset module 121 facing the crawler track 310. Compared with the above-mentioned embodiment 1, the connecting plate 132 structure is omitted.

[0089] Specifically, in this embodiment, the structure of the elastic reset module 121 remains the same as that in the above-described embodiment 1 and will not be elaborated here. Among them, the installation position of the elastic reset module 121 corresponds to the side wall of the crawler track 310, and the collision module 131 is provided on the end guide sleeve of the guide shaft 1210 facing the crawler track 310, and the collision module 131 is in rolling cooperation with the side wall of the crawler track 310.
