Description

An integrated crawler chain plate and walking crawler Technical Field

[0001] The present invention relates to a crawler traveling mechanism, in particular to an integrated crawler chain plate and a traveling crawler. Background Art

[0002] The crawler track of a crawler mechanism often uses a structure that combines a track and a crawler chain. However, the dimensions of both the track and the crawler chain are limited, resulting in insufficient structural strength. Furthermore, the installation structure is complex, making assembly and maintenance difficult. Therefore, it is necessary to optimize the structure of the crawler chain and crawler track to overcome these drawbacks. Technical issues

[0003] The object of the present invention is to provide an integrated crawler chain plate and a walking crawler, so as to facilitate assembly and maintenance of the crawler and improve the structural strength of the crawler. Technical Solutions

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] An integrated crawler chain plate includes a load-bearing assembly component, on which are provided:

[0006] The wheel body positioning structure is formed on the top of the load-bearing assembly component and cooperates with the supporting rollers to position the supporting rollers;

[0007] A grip enhancement structure formed at the bottom of the load-bearing assembly member and cooperating with the ground to improve the grip performance of the load-bearing assembly member and to provide structural reinforcement to the load-bearing assembly member;

[0008] A recessed matching structure is formed at the front and rear of the load-bearing assembly member and is recessed into the load-bearing assembly member;

[0009] The convex matching structure is formed at the front and rear of the load-bearing assembly component and protrudes toward the outside of the load-bearing assembly component. Its shape is adapted to the concave matching structure. Adjacent load-bearing assembly components can be matched with each other through the convex matching structure and the concave matching structure.

[0010] Specifically, the load-bearing assembly components include:

[0011] The load-bearing base plate is in the shape of a strip and extends along the axial direction of the walking track. Multiple load-bearing base plates can be connected end to end to form the walking track.

[0012] The wheel positioning structure includes:

[0013] A pair of positioning iron teeth are provided, each of which is formed on the top surface of the load-bearing base plate and protrudes above the load-bearing base plate. Positioning grooves that cooperate with the supporting wheels are formed between the positioning iron teeth. The supporting wheels are axially positioned by the positioning grooves and the positioning iron teeth. The positioning iron teeth are staggered in the axial direction of the load-bearing base plate.

[0014] The grip-enhancing structure includes:

[0015] A reinforcing ridge is formed on the bottom surface of the load-bearing base plate and protrudes downward to increase the grip of the load-bearing base plate. The reinforcing ridge corresponds to the position of the recessed matching structure and extends along the axial direction of the load-bearing base plate to provide structural reinforcement for the recessed matching structure.

[0016] A reinforcement groove is formed on the bottom surface of the load-bearing substrate and is recessed into the interior of the load-bearing substrate to increase the grip performance of the load-bearing substrate; in one embodiment of the present invention, the inner wall of the reinforcement groove has a transition step, and notches of different depths are formed on both sides of the transition step.

[0017] The recessed matching structure includes:

[0018] The matching end tubes are provided with two pairs and are formed at the front and rear of the load-bearing base plate. Each pair of matching end tubes is arranged along the length direction of the load-bearing base plate and is arranged at both ends of the load-bearing base plate. Matching recesses are formed between the matching end tubes. The reinforcing ridges correspond to the positions of the matching recesses, so that the matching recesses form a semi-enclosed structure.

[0019] The convex position matching structure includes:

[0020] A pair of matching sleeves are provided and formed at the front and rear of the load-bearing base plate. Each matching end tube is arranged along the length direction of the load-bearing base plate and corresponds to the position of the matching recess. The matching sleeves of adjacent load-bearing base plates can extend into the matching recess.

[0021] A walking crawler, assembled by using the above-mentioned integrated crawler chain plate, comprises:

[0022] A load-bearing base plate is provided in a group, wherein adjacent load-bearing base plates are connected end to end to form a ring, and matching sleeves of adjacent load-bearing base plates extend into matching recesses;

[0023] A group of pivoting shafts are provided. Each pivoting shaft is located between adjacent load-bearing base plates and passes through the matching sleeve and the matching end tube. The adjacent load-bearing base plates can be deflected by the pivoting shafts.

[0024] Also includes:

[0025] The buffer buckle is arranged on the pivot shaft and is located between the matching sleeve and the matching end pipe. The buffer buckle fixes the contact surface between the matching end pipe and the matching sleeve and prevents the pivot shaft from loosening. Beneficial effects

[0026] The advantages of the present invention are:

[0027] 1. The track chain plate is provided with a wheel body positioning structure consisting of a pair of positioning iron teeth on the top surface of the load-bearing base plate. A positioning notch is formed between the positioning iron teeth to cooperate with the supporting roller. The supporting roller is axially positioned by the positioning notch and the positioning iron teeth. At the same time, the positioning iron teeth are staggered in the axial direction of the supporting base plate and complement each other, so that the upward arrangement of the positioning iron teeth in the crawler track is more continuous, which can prevent the crawler track from slipping axially on the supporting roller.

[0028] 2. The crawler chain plate is equipped with a grip reinforcement structure consisting of reinforcing ridges and reinforcing grooves on the bottom surface of the load-bearing base plate to enhance the grip performance of the load-bearing base plate. The grip reinforcement structure corresponds to the position of the concave matching structure and extends along the axial direction of the load-bearing base plate to provide structural reinforcement for the concave matching structure.

[0029] 3. The crawler chain adopts a pivoting shaft that passes through the matching sleeve and the matching end tube. The adjacent load-bearing base plates can be deflected by the pivoting shaft, so that multiple load-bearing base plates enclose and form a ring-shaped walking crawler track. That is, the chain track and the chain plate are integrated, and its structure is simplified, which is easy to assemble and maintain. The structural strength of the crawler track can be adjusted by changing the thickness of the load-bearing base plate to adapt to different engineering equipment.

[0030] 4. This crawler chain features a buffer buckle mounted on the pivot shaft, securing the contact surface between the connecting end tube and the connecting sleeve. This reduces operating noise, ensures stable crawler operation, and extends service life. Enter a technical problem description paragraph here. BRIEF DESCRIPTION OF THE DRAWINGS
