Casting track shoe structure

Technical Field

The utility model relates to an engineering vehicle auxiliary assembly technical field especially relates to a casting grip-pad structure.

Background

The creeper tread is one of chassis parts of the engineering machinery and is a wearing part of the used engineering machinery. In engineering machines such as excavators, bulldozers, crawler cranes, pavers and the like, the crawler plates are mostly cast and formed structures, and the existing crawler plate structures are inverted U-shaped structures. In use, because the weight of a vehicle and the operation environment are severe, two ends of a track shoe are easy to warp, the service life is shortened, a bulge on the track shoe is a part which is easy to wear, the worn track shoe needs to be integrally replaced, the material waste is caused, and the cost of investment and use is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a damage consumptive material is low to the problem that exists among the background art, and even casting track plate structure in the hand.

The technical scheme of the utility model: the utility model provides a casting grip-pad structure, includes base plate one, the below of base plate one is equipped with base plate two, the sand grip is installed at the top of base plate one, be equipped with the cavity between base plate one and the base plate two, the bottom fixedly connected with connecting strip of sand grip, the slider is installed to the bottom of connecting strip, the spout has been seted up at the top of base plate one, connecting strip and the mutual adaptation of spout, the one end top of spout is equipped with the fixed block, it is equipped with the screw bolt to run through on the fixed block.

Preferably, the fixed block is fixedly connected with the outer wall of the first substrate, a threaded hole is formed in the fixed block, and the threaded bolt penetrates through the threaded hole and is matched with the threaded hole.

Preferably, the connecting bar penetrates through the top groove wall of the sliding groove and is in sliding connection with the sliding groove.

Preferably, a plurality of mounting holes are formed in the first substrate, and the cavity is in a structure like a Chinese character 'kou'.

Compared with the prior art, the utility model discloses following profitable technological effect has:

1. the utility model changes the original 'ji' shape into 'kou' shape by changing the structure of the creeper tread, so that the stress of the creeper tread is more uniform, and the service life is prolonged;

2. the utility model can change the raised line through the arrangement of the sliding groove and the threaded bolt, and can independently change the easily damaged parts without the whole waste, thereby reducing the material consumption and being suitable for popularization and application;

3. to sum up, the utility model discloses well novel structure establishes the grip-pad into the cavity, and the grip-pad atress is more even, and increase of service life changes wearing and tearing serious sand grip, reduces the waste that whole change caused, reduces use cost.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

Examples

As shown in figure 1, the utility model provides a casting track plate structure, including a base plate 1, a base plate 2 is arranged below the base plate 1, a cavity 4 is arranged between the base plate 1 and the base plate 2, the cavity 4 is in a structure like a Chinese character 'kou', a raised line 3 is arranged on the top of the base plate 1, referring to figures 3 and 4, a connecting bar 7 is fixedly connected with the bottom of the raised line 3, a slide block 6 is arranged on the bottom of the connecting bar 7, the slide block 6 and the connecting bar 7 form a structure like a Chinese character 'T', a slide groove 5 is arranged on the top of the base plate 1, the vertical section of the slide groove 5 is in a shape like a 'T', the connecting bar 7 and the slide groove 5 are mutually matched, the connecting bar 7 penetrates through the top groove wall of the slide groove 5 and is in sliding connection with the slide groove 5, a fixing block 9 is arranged above one end of the slide groove 5, a threaded bolt 10 is arranged on the fixing block 9, the fixing block 9 is fixedly connected with the outer wall of the base plate 1, and set up the screw hole on the fixed block 9, the other end of screw bolt 10 is contradicted with one side outer wall of sand grip 3, and screw bolt 10 runs through the screw hole and with screw hole mutual adaptation, refer to fig. 2, set up a plurality of mounting holes 11 on the base plate 1.

In this embodiment, referring to fig. 5, the connecting cavity 12 of the original track plate structure is a structure shaped like a Chinese character 'ji'; the existing casting cavity 4 is of a 'square' -shaped structure and is used for changing a cavity structure, so that the stress of the track shoe is more uniform, and in long-time use, the abrasion of the convex strip 3 is serious, therefore, when the track shoe is replaced and used, only the convex strip 3 needs to be replaced, when the convex strip 3 is replaced, the threaded bolt 10 is rotated along a threaded hole in the fixed block 9 until the threaded bolt 10 is separated from the fixed block 9, after the threaded bolt 10 is collided with the convex strip 3 and disappears, the convex strip 3, the sliding block 6 and the connecting strip 7 are pulled along the sliding groove 5, so that the connecting strip 7 is separated from the sliding groove 5, the disassembly of the convex strip 3 can be completed, and during installation, a new convex strip 3, a sliding block 6 and a new connecting strip 7 are pushed along the sliding groove 5.

The above embodiments are merely preferred embodiments of the present invention, and those skilled in the art can make various alternative modifications and combinations based on the technical solution of the present invention and the related teachings of the above embodiments.
