Description

Technical Field

[0001] The invention relates to the field of track shoes, and in particular to a split combined track shoe structure for engineering machinery. Background Art

[0002] Track shoes are key components of construction machinery and are widely used in excavators, bulldozers, crawler cranes, pavers and other equipment. Their main function is to bear the weight of the machine and transmit power and travel through friction with the ground. As a key component of the walking system of construction machinery, the structural design of the track shoe directly affects the stability and operating efficiency of the machine.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0033] like Figure 1-7 As shown, the present invention proposes a split combined crawler shoe structure for engineering machinery, the bracket mechanism includes an "H-shaped" bracket 11, a horizontal plate 12 for separating the upper and lower cavities is installed in the middle of the bracket 11, and the upper and lower parts of the horizontal plate 12 are respectively provided with a laterally protruding inner clamping plate 13 and an outer clamping plate 14;

[0034] The inner clamping plate 13 and the inner clamping member 23 are in one-way raised contact, which increases the one-way reinforcement of the inner track shoe 21 and the upper part of the bracket 11;

[0035] The outer clamping plate 14 and the outer clamping member 33 are in bidirectional convex contact, which increases the bidirectional reinforcement of the lower part of the outer track shoe 31 and the bracket 11;

[0036] The inner crawler mechanism includes an inner crawler shoe 21, one end of the inner crawler shoe 21 penetrating into the upper cavity is an inner load-bearing member 22, and is clamped to the outer side of the inner clamping plate 13 through a symmetrical inner clamping member 23;

[0037] The outer crawler mechanism includes an outer crawler shoe 31 which is arranged in sections. One end of the outer crawler shoe 31 which penetrates into the inner cavity is an outer load-bearing member 32, and is clamped to the outer side of the outer clamping plate 14 through a symmetrical outer clamping member 33.

[0038] The buffer mechanism includes a slide rail 61 disposed in the transverse plate 12, a slide seat 62 that can slide is disposed in the slide groove of the slide rail 61, a spring member 63 is disposed at the bottom of the slide seat 62, and the other end of the spring member 63 is connected to the external bearing member 32 through a support plate 64;

[0039] The monitoring mechanism includes a guide seat 71 and a movable rod 72 respectively connected to the support plate 64 and the slide 62. The guide seat 71 and the movable rod 72 are movable structures. The support plate 64 and the slide 62 are also provided with a ranging sensor 74 and a ranging plate 75 that cooperate with each other. The ranging sensor 74 transmits signals through the communication device 73.

[0040] It should be noted that: the outer track shoe 31 is provided with at least three sections, and the specifications and structures of the three sections of the outer track shoe 31 are the same; the outer track shoe 31 directly contacts the road surface during the operation of the engineering machinery, and the outer track shoe 31 is a vulnerable component. By improving the outer track shoe 31 to a segmented design, the damaged outer track shoe 31 can be replaced in time.

[0041] In this embodiment, the outer track shoe 31 slides in the slide groove 62 of the slide rail 61 through the slide seat 62, and the outer bearing member 32 is slid into the lower cavity separated by the partition plate 12. During the working process, the buffer mechanism has a spring member 63 with an elastic structure built in. When the outer track shoe 31 is deformed by the reaction force of the road surface, the outer bearing member 32 is compressed and deformed upward to drive the spring member 63 to compress, so as to disperse the reaction force of the road surface, thereby achieving the buffering of the impact on the outer track shoe 31.

[0042] In cooperation with the monitoring mechanism, when the spring member 63 is deformed by the reaction force, because the guide seat 71 and the movable rod 72 are sleeved, the guide seat 71 and the movable rod 72 are relatively movable, and the rays emitted by the ranging sensor 74 are fed back through the ranging plate 75, and the deformation amplitude of the spring member 63 can be known. When the deformation amplitude exceeds the maximum compression stroke of the spring member 63, it means that the strength of the outer track plate 31 has decreased and there is a risk of damage. When the spring member 63 cannot restore the initial stroke when resetting, and the distance monitored by the ranging sensor 74 is always lower than the initial preset value, it also means that the strength of the outer track plate 31 has decreased and there is a risk of damage. The cooperation of the ranging sensor 74 and the communication device 73 can timely determine the position of the damaged outer track plate 31, which is convenient for subsequent maintenance and replacement.

[0043] The distance sensor 74 and the distance plate 75 are arranged in parallel, and the communication device 73 connected to the distance sensor 74 signal is connected to the vehicle terminal of the engineering machinery through a wireless network to perform monitoring feedback of any outer track shoe 31.

[0044] like Figure 5 As shown, a protruding positioning block 641 and a positioning column 642 are provided at the bottom of the support plate 64 , and a positioning block groove 643 and a positioning column groove 644 matching with the support plate 64 are opened on the outer bearing member 32 .

[0045] In order to assist the connection between the buffer mechanism and the outer crawler mechanism, the positioning column 642 at the bottom corner of the support plate 64 is inserted into the positioning column groove 644 to guide the positioning block 641 before inserting it into the positioning block groove 643. After the positioning block 641 and the positioning block groove 643 are firmly plugged in, the combination of the outer crawler plate 31 and the support plate 64 is achieved by a five-point positioning method.

[0046] As an example of the assembly of the inner and outer crawler mechanisms on the support mechanism:

[0047] The locking bolt mechanism includes an outer track shoe bolt hole 81 provided on the side of the bracket 11 and the outer clamping plate 14, and the outer track shoe bolt hole 81 and the inner clamping member 23 are plugged and fixed by an outer track shoe bolt 82;

[0048] When installing the outer track shoe 31, slide the outer track shoe 31 and the slide seat 62 matched therewith along the slide groove of the slide rail 61 toward the inside of the bracket 11. At this time, the outer load-bearing member 32 is embedded in the lower cavity of the bracket 11, and the outer clamping member 33 is attached and engaged with the outer clamping plate 14. The outer track shoe bolt 82 is respectively inserted into the two outer track shoe bolt holes 81 in the lateral and oblique directions to fix the outer clamping member 33, the bracket 11 and the outer clamping plate 14 at multiple points.

[0049] An inner track shoe bolt hole 83 is provided on one side of the bracket 11 close to the inner clamping plate 13, and the inner track shoe bolt hole 83 and the inner track shoe 21 are plugged and fixed by an inner track shoe bolt 84;

[0050] When installing the inner track shoe 31, the inner load-bearing member 22 of the inner track shoe 21 is embedded in the upper cavity of the bracket 11. At this time, the inner clamping member 23 and the inner clamping plate 13 are attached, and the inner track shoe bolt 84 is passed through the inner clamping member 23, the bracket 11 and the inner load-bearing member in sequence to fix the inner track shoe mechanism on the bracket mechanism.

[0051] In order to facilitate the rotation of the track system composed of the inner track shoe 21 along the outside of the driving wheel, further, the upper part of the inner track shoe 21 is symmetrically provided with concave tooth grooves 24, and the gear teeth of the driving wheel are relatively meshed with the tooth grooves 24. During the staggered meshing process, the inner track shoe 21 is switched to assist the rotation of the track system.

[0052] In order to adapt to muddy roads, further, a mud guide groove 34 with a “wave structure” is opened at the lower part of the outer track shoe 31 .

[0053] like Figure 2 As shown, the front and rear ends of the bracket 11 are respectively installed with a first axis frame 41 and a second axis frame 42, and adjacent track shoes are assembled through the first axis frame 41 and the second axis frame 42 and the shaft rod.

[0054] It should be noted that, since the first axle frame 41 and the second axle frame 42 are staggered, the through holes of the first axle frame 41 and the second axle frame 42 of the adjacent track shoes are attached, the shaft rod is passed through the combined channel of the first axle frame 41 and the second axle frame 42, and the protruding ends of the shaft rod passing through the first axle frame 41 and the second axle frame 42 combined as a whole are limited to the outside by external rings, thereby ensuring that the track shoes can rotate with the shaft frame sleeved on the outside of the shaft rod.

[0055] like Figure 4 As shown, the side crawler mechanism includes a slot 51 opened on the side wall of the bracket 11, a card plate 52 is inserted into the slot 51, the other end of the card plate 52 is connected to a side crawler shoe group 53 attached to the inner crawler shoe 21 and the outer crawler shoe 31, and a vertical rod 54 for auxiliary support is installed in the middle of the side crawler shoe group 53.

[0056] It should be noted that in order to seal the sides of the integral connection between the inner track shoe mechanism and the outer track shoe mechanism and the bracket mechanism, the clamping plate 52 of the side track shoe group 53 and the clamping groove 51 of the side wall of the bracket 11 are engaged and fixed, so as to achieve close adhesion between the upper and lower parts of the side track shoe group 53 and the inner track shoe 21 and the outer track shoe 31, and at the same time play a certain lateral limiting role.

[0057] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
