Problems solved by technology

[0002] The chain link group is the most important part of the track, which plays the role of supporting weight and transmitting the driving force; the track shoe is one of the important parts of the track, which plays the role of supporting, anti-skid, increasing adhesion, and transmitting the driving force; The track shoes are fixed on the chain rail link group by bolts, and the force transmission is realized through the fastened bolts; due to the harsh working conditions of excavators, especially large mining excavators, when the track shoes and the chain rail link group slip When moving, the track bolts will bear a large shear force, which will easily cause the track bolts to break and the track shoes to fall off.

Embodiment 1

[0038] see Figure 1 to Figure 4 As shown, the track assembly unit provided by the present application includes a chain rail link group 101, a track shoe 102 and a connector 103; the chain rail link group 101 and the track shoe 102 are connected through the connector 103; the track shoe 102 is provided with The positioning groove 104 and the chain rail segment group 101 are provided with a positioning protrusion 105 , and the positioning protrusion 105 can be inserted into the positioning groove 104 for positioning the relative positions of the chain rail segment group 101 and the track shoe 102 .

[0039]Specifically, the crawler assembly unit includes a chain rail link group 101 , a crawler shoe 102 and a connecting piece 103 . Among them, the chain rail link group 101 is the most important part of the crawler belt, which plays the role of supporting weight and transmitting driving force; The effect of force; the chain rail segment group 101 and the track shoe 102 are attac...

Embodiment 2

[0051] The second embodiment is an improvement on the basis of the above embodiment, and the technical content disclosed in the above embodiment will not be described repeatedly, and the content disclosed in the above embodiment also belongs to the content disclosed in the second embodiment.

[0052] see Figure 5 As shown, in the optional case of this embodiment, the chain rail section group 101 includes a first chain rail section 108 and a second chain rail section 109; the first chain rail section 108 and the second chain rail section 109 are symmetrically arranged, and the first chain rail section 109 Both the chain rail segment 108 and the second chain rail segment 109 are connected to the track shoe 102 .

[0053] In this embodiment, the first chain rail link 108 and the second chain rail link 109 are arranged symmetrically on the track shoe 102, so that the force of the whole structure is more balanced.

[0054] In the optional solution of this embodiment, the chain ra...

Embodiment 3

[0057] Embodiment 3 of the present application provides a crawler belt assembly, including a plurality of crawler belt assembly units in any one of the above embodiments, and multiple crawler belt assembly units are connected in sequence, see Image 6 As shown, for the convenience of expression, only the schematic diagram of the connection between two crawler assembly units is shown in the figure, and the connection methods of other crawler assembly units are the same. The crawler belt assembly has all the beneficial technical effects of the crawler belt assembly unit in any of the above embodiments, which will not be repeated here.

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a crawler assembly unit and a crawler assembly. The crawler assembly unit comprises a chain track joint group, a crawler plate and a connecting part; the chain track joint group and the crawler plate are connected by the connecting part; and the crawler plate is provided with a positioning groove, a positioning bulge is arranged on the chain track joint group, and the positioning bulge can be placed into the positioning groove for positioning the relative position of the chain track joint group and the crawler plate. According to the crawler assembly unit and the crawler assembly, through the positioning groove formed in the crawler plate, the chain track joint group is provided with a positioning bulge which is placed into the positioning groove to realize accuracy positioning of the crawler plate, transverse shear and torsional force on the connecting part are reduced, and fracture of the connecting part under the force is prevented.
