Track shoe with high road holding force

Abstract

The utility model discloses a creeper tread with high road holding force, which comprises a hollow creeper tread body, the middle part of the creeper tread is provided with a ground holding plate which is in bilateral symmetry, the ground holding plate comprises at least two plate body units which are arranged on the creeper tread body in a sliding mode, a sliding block is arranged in the creeper tread body in a sliding mode, and the sliding block is matched with the plate body units through mutually-abutted inclined planes. After being stressed, the plate body units slide towards the interior of the track shoe body and push the sliding blocks to slide under the action of the inclined planes which abut against each other, so that the sliding blocks push the other plate body units to stretch out, and different plate body units stretch out by different lengths. The multiple floating ground grabbing plates are arranged and float up and down due to different stress between the ground grabbing plates, even if one of the ground grabbing plates encounters an ore block, the other ground grabbing plates can still prick into the ground to provide enough ground grabbing force, and in addition, when the ground is just in contact with the ground, the ground grabbing plates cannot be damaged. The first contact part indirectly pushes the second contact part to extend out so as to be better inserted into the ground.

Description

Technical Field

[0001] The utility model relates to a crawler plate for mining machinery, in particular to a crawler plate with high gripping power. Background Art

[0002] With the development and progress of engineering machinery design and manufacturing technology, the demand for high-alloy steel track shoes for mining machinery has increased significantly, and the technical and quality requirements have been continuously improved. Track shoes are one of the chassis parts of engineering machinery, used in excavators, bulldozers, etc., and are important parts for manufacturing to withstand impact and high loads.

[0003] At present, the gripping force of the track shoe is generally provided by setting a gripping plate at the bottom of the track shoe, and the gripping plate is penetrated into the soil to provide gripping force. For example, the patent with application number CN201780037947.1 discloses a track shoe assembly, including a driving lug part and a track shoe body, and the track shoe body includes a driving lug cavity for accommodating the driving lug component. The driving lug component has at least one lug portion protruding in a first direction, and at least one supporting protrusion extending in a direction substantially opposite to the first direction. The at least one supporting protrusion is configured to be placed in the driving lug cavity formed in the track shoe, so that the load applied to the driving lug part is at least partially transferred to the track shoe.

[0004] The above patent increases the grip by providing lugs, but when the lugs encounter ore blocks, the lugs are unable to penetrate completely due to the large resistance of the ore blocks, resulting in failure to provide the required grip. Utility Model Content

[0005] Based on the deficiency that the lugs of the track shoe in the prior art cannot provide sufficient gripping force when encountering ore blocks, the utility model provides a track shoe with high gripping force.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A track shoe with high gripping force comprises a hollow track shoe body, a left-right symmetrical gripping plate in the middle of the track shoe, the gripping plate comprising at least two plate units slidably arranged on the track shoe body, a slider is slidably arranged in the track shoe body, the slider and the plate unit cooperate through mutually abutting inclined surfaces, the plate unit slides into the track shoe body after being subjected to force and pushes the slider to slide under the action of the mutually abutting inclined surfaces so that the slider pushes another plate unit to extend so that different plate units extend to different lengths. This scheme provides a floating gripping plate, which pushes the other plate to rise and fall according to the respective forces when it penetrates into the ground and penetrates into the ground to provide sufficient gripping force.

[0008] Preferably, the gripping plate includes two pieces and the slider is provided with one piece, namely the first plate unit and the second plate unit. The right side of the first plate unit and the left side of the second plate unit are provided with left-right symmetrical inclined surfaces, and the left and right sides of the slider are respectively provided with inclined surfaces that are in contact with the inclined surfaces on the two plate units.

[0009] Preferably, the gripping plate comprises a first plate unit, a second plate unit and a third plate unit, and two sliders are arranged in the track plate body, one of which is located between the first plate unit and the second plate unit and both have inclined surfaces abutting against each other, and the other slider is located between the second plate unit and the third plate unit and both have inclined surfaces abutting against each other.

[0010] Preferably, the track shoe is provided with a plurality of sliding holes, each plate unit is located in the sliding hole, and the portion of each plate unit extending into the interior is provided with a limiting structure for preventing the plate unit from falling out of the sliding hole.

[0011] Preferably, the limiting structure is a limiting boss or a limiting pin inserted into the plate unit.

[0012] Preferably, the gripping plate is arranged on the bottom plate of the track shoe body, and the bottom plate around the sliding hole extends upward to form a reinforcement platform.

[0013] Preferably, the first plate unit, the second plate unit and the third plate unit all have sliding parts and there is a gap between two adjacent sliding parts. The first plate unit and the third plate unit are provided with horizontal extension parts at the bottom, and the two extension parts respectively abut against the side walls of the second plate unit.

[0014] Preferably, a slideway for the sliding block to slide is provided in the plate body.

[0015] Preferably, an anti-skid structure is provided on the track shoe body, and the anti-skid structure includes an anti-skid rack arranged between two gripping plates.

[0016] Preferably, an arc-shaped groove is provided between the two gripping plates, and the rack is arranged in the arc-shaped groove.

[0017] Compared with the prior art, the advantages of the utility model are as follows: the utility model provides several floating gripping plates, which float up and down due to the different forces between the gripping plates. Even if one of the gripping plates encounters a rock, the other gripping plates will still penetrate into the ground to provide sufficient grip. In addition, when the gripping plates just come into contact with the ground, the first gripping plates will indirectly push the later gripping plates to extend so as to better penetrate into the ground.
