Abstract
The utility model discloses a composite track shoe, belonging to the track shoe of a bulldozer, and comprising a mainboard (1) and a convex pin (3). As the mainboard (1) and the convex pin (3) adopt a machinery mode to connect, only the convex pin (3) which is easy to be worn during using needs to be changed, so that the cost is reduced greatly, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of caterpillar block of bulldozer.
Background technology
The caterpillar block of existing bulldozer is an integral type, it goes up work in hard material (as ore, stone etc.), its life-span was generally about 1500 hours, the protruding pin abrasion loss of caterpillar block reaches 50～70%, cause caterpillar block to skid, so work efficiency descends greatly, so that can't use, and must monoblock change.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide-kind of combined type caterpillar block, and it is divided into mainboard and protruding pin, both mechanical connections.After protruding pin weares and teares in the course of the work, only need to change protruding pin and can continue to use.
Above-mentioned purpose is achieved in that the combined type caterpillar block, comprises mainboard and protruding pin, and a raised platforms is arranged on the mainboard, platform and protruding pin mechanical connection.When bolt together or riveted joint, several corresponding through holes are arranged on platform and the protruding pin, so that both connect; The also available welding manner of platform and protruding pin is connected and fixed.
The combined type caterpillar block is skillfully constructed, modern design, and mainboard need not changed, and only changes protruding pin, greatly reduces the price of caterpillar block, and saves great deal of steel.Simple in structure, productive costs is low, and changing once protruding pin expense is 1/4～1/3 of entire track plate.Changing protruding pin ratio, to change integral body be that the caterpillar block time is short, improved work efficiency.

The specific embodiment
The combined type caterpillar block comprises mainboard 1 and protruding pin 3, and a raised platforms is arranged on the mainboard, and 5 through holes are arranged on platform and the protruding pin 3, and through hole and protruding pin are connected and fixed with bolt 2 on the platform.After protruding pin 3 weares and teares in the course of the work, only need to change protruding pin and can continue to use by demounting bolt 2.But platform and protruding pin 2 be riveted and fixed also; The also available welding manner of platform and protruding pin is connected and fixed.
Claims (3)
1. a combined type caterpillar block comprises mainboard (1) and protruding pin (3), it is characterized in that: a raised platforms is arranged, platform and protruding pin (3) mechanical connection on the mainboard.
2. according to the described combined type caterpillar block of claim 1, it is characterized in that: platform when being connected, has several corresponding through hole on platform and the protruding pin (3) with bolt (2) with protruding pin (3).
