Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of track shoe, concretely is a modular track shoe. BACKGROUND
[0002] The track shoe is an important component of the track walking device, which is a component installed on the track pin and directly contacted with the ground. As a common engineering equipment, the bulldozer is widely used in road construction, land leveling, farmland reconstruction and other engineering. In the land leveling operation, the bulldozer needs to push the soil and other materials on the unlevelled land. The track shoe can provide greater driving force and good adhesion, even if there is water, mud and other conditions on the ground, it can also push a large amount of materials to work. In the early stage of road construction, the bulldozer can work on the soft roadbed with the help of the track shoe, which lays the foundation for the subsequent construction vehicles to pave the road.
[0003] The significant difference from other engineering equipment is that the weight of the bulldozer is mainly transmitted to the ground through the track shoe, which makes the track shoe bear a larger contact pressure. Especially when the bulldozer is working under heavy load, the contact pressure will further increase, accelerating the wear of the track shoe. Considering the actual working scene of the bulldozer, in order to avoid frequent replacement of the track shoe, a wear-resistant reinforcing rib is usually arranged on the side of the track shoe in contact with the ground, thereby improving the service life of the track shoe, and also improving the adhesion of the track shoe. However, in the prior art, the reinforcing rib is directly welded on the surface of the track shoe, and after the reinforcing rib is worn to a certain extent, the contact pressure between the track shoe and the ground will decrease, resulting in insufficient adhesion of the bulldozer and poor bulldozing effect. In addition, the track shoe will gradually wear out in direct contact with the ground, and the track shoe still needs to be replaced as a whole. Therefore, a modular track shoe is proposed. UTILITY MODEL CONTENTS
[0004] The utility model aims at providing a modular track shoe to solve the problem that the service life of the track shoe is effectively prolonged by welding the reinforcing rib on the surface of the track shoe applied to the bulldozer, but the track shoe still needs to be replaced as a whole after the reinforcing rib is worn out, resulting in high replacement cost.
[0005] To solve the above technical problems, the utility model provides the following technical scheme:
[0006] A modular track plate includes a plate body, a first connecting protrusion, a second connecting protrusion, a track link mounting groove, a screw groove, a positioning docking groove, a fixing pin, connecting teeth, and an anti-slip strip assembly. The first and second connecting protrusions are integrally formed on both sides of the plate body. The positioning docking groove is formed on the upper surface of the plate body. Both track link mounting grooves are formed on the upper surface of the plate body and are symmetrically arranged about the positioning docking groove. The screw groove is formed on the plate body and is located in the track link mounting groove. The connecting teeth fit into the positioning docking groove. The fixing pin passes through the side wall of the plate body, and the end of the fixing pin passes through the connecting teeth. A strip groove is formed on the lower surface of the plate body, and the anti-slip strip assembly fits into the strip groove.
[0007] Preferably, both the first connecting protrusion and the second connecting protrusion are provided with connecting holes, and the distance between the positioning pin holes on the first connecting protrusion and the edge of the plate is equal.
[0008] Preferably, the positioning and docking groove includes a deep groove, a shallow groove, a circular groove, a pin hole, and a straight groove. The deep groove is opened at the center of the upper surface of the plate, the shallow groove is located on both sides of the deep groove, the circular groove is located in the shallow groove, the pin hole is opened on the side wall of the plate, and the axis of the pin hole and the axis of the circular groove are in the same straight line direction. The straight grooves are evenly distributed in the deep groove.
[0009] Preferably, the connecting protrusion includes a tooth block, side plates, a strong magnetic block, and an insert block. The two side plates are integrally formed on both sides of the tooth block, the strong magnetic block is attracted to the bottom of the tooth block, the insert block is connected between the strong magnetic block and the tooth block, the tooth block is fitted into a deep groove, the side plates are fitted into a shallow groove, and the strong magnetic block is fitted into a slot.
[0010] Preferably, the anti-slip strip assembly includes an adhesive plate, anti-slip blocks, reinforcing plates, and fixing bolts. The adhesive plate is attached to the strip groove, the anti-slip blocks are installed at equal intervals on the surface of the adhesive plate, the reinforcing plates are installed on the bottom surface of the adhesive plate, and the fixing bolts pass through the adhesive plate and connect to the plate body.
[0011] Preferably, the strip groove is provided with equally spaced bonding grooves, and the bottom of the bonding plate is integrally formed with equally spaced reinforcing pieces. When the bonding plate is bonded to the strip groove, the reinforcing pieces are bonded to the bonding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of the strip groove, the fitting groove, and the anti-slip strip assembly, when applied to bulldozers, takes into account the significant wear and tear on the track plates caused by the actual working conditions of bulldozers. After a period of use, when the wear of the anti-slip strip assembly reaches the point of replacement, the anti-slip strip assembly can be replaced separately without replacing the track plate itself. This not only reduces the cost of using the track plates but also ensures the grip of the track plates by timely and conveniently replacing the anti-slip strip assembly, thereby fully guaranteeing the bulldozing effect of the bulldozer.

The positioning docking groove 7 is formed on the plate body. On the upper surface of the plate 1, two track link mounting grooves 5 are both formed on the upper surface of the plate 1 and are symmetrically arranged about the positioning docking groove 7. A screw groove 6 is formed on the plate 1 and is located in the track link mounting groove 5.

During installation, the connecting pins corresponding to the size of the connecting holes 4 are passed through the first connecting protrusion 2 and the second connecting protrusion 3 that are positioned and fitted, so that the adjacent plates 1 can be connected to form a track.
[0027] Reference Figure 2As one embodiment of this utility model, specifically, the positioning and docking groove 7 includes a deep groove 71, a shallow groove 72, a circular groove 73, a pin hole 74, and a straight groove 75. The deep groove 71 is opened at the center of the upper surface of the plate 1, the shallow groove 72 is located on both sides of the deep groove 71, the circular groove 73 is located in the shallow groove 72, the pin hole 74 is opened on the side wall of the plate 1, and the axis of the pin hole 74 is in the same straight line direction as the axis of the circular groove 73. The straight grooves 75 are evenly distributed in the deep groove 71. The deep groove 71, shallow groove 72, circular groove 73, and straight groove 75 are formed together by using a special mold during the hot stamping of the plate 1. After the plate 1 undergoes multiple heat treatments, the pin hole 74 is formed on the side wall of the plate 1 using a drilling tool.
[0028] Reference Figure 2 and Figure 5 As one embodiment of this utility model, specifically, the connecting tooth 9 includes a tooth block 91, a side piece 92, a strong magnetic block 93, and an insert block 94. The two side pieces 92 are integrally formed on both sides of the tooth block 91, the strong magnetic block 93 is adsorbed on the bottom of the tooth block 91, and the insert block 94 is connected between the strong magnetic block 93 and the tooth block 91. The tooth block 91 is fitted in the deep groove 71, the side piece 92 is fitted in the shallow groove 72, and the strong magnetic block 93 is fitted in the slot 75. Under the action of the strong magnetic block 93, the magnetic block, the side piece 92, and the insert block 94 can be quickly positioned and fitted with the plate 1, thereby improving the modular installation efficiency between the connecting tooth 9 and the plate 1.
[0029] Reference Figure 4 As one embodiment of this utility model, specifically, the anti-slip strip assembly 10 includes a bonding plate 101, anti-slip blocks 102, reinforcing plates 103, and fixing bolts 104. The bonding plate 101 is bonded to the strip groove 11. The anti-slip blocks 102 are installed at equal intervals on the surface of the bonding plate 101. The reinforcing plates 103 are installed on the bottom surface of the bonding plate 101. The fixing bolts 104 penetrate the bonding plate 101 and connect to the plate body 1. The number of anti-slip strip assemblies 10 can be selected according to the actual working scenario of the bulldozer. The equally spaced anti-slip blocks 102 can ensure that there is sufficient grip between the plate body 1 and the ground.
[0030] Reference Figure 3 As one embodiment of this utility model, specifically, the strip groove 11 is provided with equally spaced bonding grooves 12, and the bottom of the bonding plate 101 is integrally formed with equally spaced reinforcing pieces 103. When the bonding plate 101 is bonded to the strip groove 11, the reinforcing pieces 103 are bonded to the bonding grooves 12. Through the provided reinforcing pieces 103, the overall strength of the bonding plate 101 and the anti-sliding block 102 can be improved. The reinforcing pieces 103 provide stronger support for the anti-sliding block 102 and facilitate the positioning and installation of the bonding plate 101 in the strip groove 11.
[0031] Reference Figure 3As one embodiment of this utility model, specifically, two side grooves 13 are provided on the lower surface of the plate 1, and the edges of the side grooves 13 are flush with the ends of the plate 1. Under the action of the side grooves 13, the gripping force between the plate 1 and the ground can be further increased, thereby improving the bulldozing efficiency of the bulldozer.
[0032] Working principle: The track plate 1, as well as the positioning docking groove 7, strip groove 11, fitting groove 12, and side groove 13 on the track plate 1, are made sequentially by forging, shearing, and stamping. Then, the connecting holes 4 are machined on the first connecting protrusion 2 and the second connecting protrusion 3 using drilling equipment, and the pin holes 74 and circular grooves 73 are machined on the side wall of the track plate 1. Correspondingly, the connecting teeth 9 and the anti-slip strip assembly 10 are made. During modular assembly, the connecting teeth 9 and the anti-slip strip assembly 10 are installed in the positioning docking groove 7 and the strip groove 11, respectively, to complete the installation of the track plate. When the anti-slip strip assembly 10 is worn to a certain extent, it can be disassembled and replaced separately, thereby fully ensuring the grip of the track plate.
[0033] Specifically, when installing the connecting tooth 9 in the positioning docking groove 7, after aligning the strong magnetic block 93 with the slot 75, the tooth block 91 and the side piece 92 are moved down in sequence along the edges of the deep groove 71 and the shallow groove 72 until the strong magnetic block 93 is quickly attracted into the slot 75. Then, the fixing pin 8 is passed through the pin hole 74, and then the fixing pin 8 is slowly rotated so that the end of the fixing pin 8 is screwed into the round groove 73. In this way, the connecting tooth 9 and the plate 1 can be fixedly installed.
[0034] When installing the anti-slip strip assembly 10 in the strip groove 11, the bonding plate 101 is bonded to the strip groove 11, and the reinforcing piece 103 then enters the bonding groove 12. Then, the fixing bolt 104 is used to pass through the bonding plate 101 and fix it to the plate body 1. In this way, the anti-slip strip assembly 10 can be installed and connected to the plate body 1. When the anti-slip slider 102 is worn to a large extent, the fixing bolt 104 is removed, the old bonding plate 101 is removed, and then a new anti-slip strip assembly 10 can be installed.
