Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to an anti-wear drag chain wheel support for a bulldozer. Background Art

[0002] A bulldozer is an earth-moving machinery that can dig, transport and dump rock and soil. It is widely used in open-pit mines to build dumping yards, level automobile dumping yards, pile up scattered ore and rock, level work platforms and construction sites. It is not only used for auxiliary work, but also for major mining work.

[0003] The existing equipment has adjustment grooves in the middle of the front, back, left and right sides of the support body, so that the adjustment bolt can be easily placed in the adjustment groove. One end of the adjustment bolt is fixedly connected to the adjustment support through a threaded connection hole. When the adjustment nut on the outer wall of the adjustment bolt is rotated, it is further convenient to adjust and fix the adjustment support, so that the drag chain wheel body can be easily adjusted. However, when the above equipment is in use, the worn position cannot be replaced. Therefore, we propose an anti-wear drag chain wheel support for a bulldozer. Utility Model Content

[0010] As a preferred technical solution of the utility model, the anti-wear plate and the arc plate are used to fix the circular wheel through a fixing assembly, and the diameter of one end of the circular ring 2 close to the circular ring 1 is twice as large as the diameter of the other end.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The anti-wear drag chain wheel support for the bulldozer has two groups of fixing components, so that after the screws are connected to the two groups of square plates through the circular groove, the second nut and the first nut are twisted and the second nut and the first nut are moved on the outer wall of the screw, so that the second nut and the first nut can fix the square plate with the screw. When the anti-wear plate is worn, it can be disassembled through the fixing component, so that the anti-wear plate can be replaced in time to avoid affecting the work efficiency.

[0013] 2. The wear-resistant drag chain wheel support for the bulldozer is connected with the rectangular groove through a slider. When the round wheel needs to be removed, it is only necessary to slide the round ring 2 with force so that the round ring 2 can slide on the outer wall of the rectangular strip. The slider is fixedly installed on the inner wall of the round ring 2. The inner wall diameter of the round ring 1 is the same as the outer wall diameter of the round ring 2, so that the round ring 2 can enter the inner cavity of the round ring 1, so that one end of the rectangular strip can be opened. At this time, the round wheel is removed, which facilitates the disassembly of the round wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Working principle: when the wear-resistant plate 2 is seriously worn and needs to be replaced, it is connected with the rectangular groove 9 through the slider. When the round wheel 1 needs to be removed, it is only necessary to slide the round ring 2 7 with force so that the round ring 2 7 can slide on the outer wall of the rectangular strip 5. The slider is fixedly installed on the inner wall of the round ring 2 7. The inner wall diameter of the round ring 1 6 is the same as the outer wall diameter of the round ring 2 7, so that the round ring 2 7 can enter the inner cavity of the round ring 1 6, so that one end of the rectangular strip 5 can be opened. At this time, the round wheel 1 is removed and fixed by the square plate 801. It is fixedly installed on the outer wall of the arc plate 3, and after being connected with the two groups of square plates 801 through the circular groove 802 by means of screws 803, by twisting nut two 805 and nut one 804, nut two 805 and nut one 804 are moved on the outer wall of the screw 803, so that nut two 805 and nut one 804 can be removed from the outer wall of the screw 803, so that the two groups of fixing components 8 can be disengaged, so that the fixing components 8 drive the arc plate 3 and the anti-wear plate 2 to be disengaged, so that the anti-wear plate 2 can be replaced.
