Abstract
A kind of take-up pulley connection structure of open cast mine large excavator, comprise: crawler rack, described crawler rack also comprises take-up pulley, described take-up pulley center wheel bore fixed conveyor axle, the transmission shaft stretching out described take-up pulley both sides is socketed copper sheathing respectively, and described copper sheathing one end is provided with the step of evagination, and described step and described take-up pulley side offset, described copper sheathing overcoat female connector cartridge type axle bed, described axle bed one end and described step offset.Change the mounting structure of take-up pulley, add the area of contact of relative motion, improve stressed, extend the service life of copper sheathing.Structure is simple, is convenient to repair and replacement, reduces the maintenance cost of user.Solve copper sheathing serious wear, inconvenience is safeguarded in assembling.
Description
Technical field
The utility model relates to a kind of take-up pulley connection structure of open cast mine large excavator.
Background technology
At present, the take-up pulley on crawler rack and transmission shaft are two parts of relative motion, and to the copper sheathing serious wear of the linking effect of wherein assembling in relative movement, because the reason of build-up tolerance, copper sheathing is consumable accessory, and not easily changes.Copper sheathing, once wearing and tearing, in use brings very large inconvenience to user, also increases the maintenance cost of user, so need a kind of take-up pulley connection structure of open cast mine large excavator badly, solve copper sheathing serious wear, and the problem of inconvenience is safeguarded in assembling.
Summary of the invention
The purpose of this utility model is the take-up pulley connection structure providing a kind of open cast mine large excavator, take-up pulley and tension axle is designed to two workpiece of the not relative motion of one, solves copper sheathing stressed bad easy to wear, the problem that maintenance is inconvenient.
The utility model adopts following technical scheme:
A kind of take-up pulley connection structure of open cast mine large excavator, comprise: crawler rack, described crawler rack also comprises take-up pulley (1), described take-up pulley (1) center wheel bore fixed conveyor axle (2), the transmission shaft (2) stretching out described tension axle (1) both sides is socketed copper sheathing (3) respectively, described copper sheathing (3) one end is provided with the step (31) of evagination, described step (31) and described take-up pulley (1) side offset, described copper sheathing overcoat female connector cartridge type axle bed (4), described axle bed (4) one end and described step (31) offset.
Described take-up pulley (1) two sides are provided with concave station (5), and described step (31) one end is lying in described concave station (5).
Advantage of the present utility model is as follows:
1. change the mounting structure of take-up pulley, the stressed strong point lengthens, and copper sheathing area of contact increases, the service life extended.
2. structure is simple, is convenient to repair and replacement, reduces the maintenance cost of user.
Accompanying drawing illustrates:
Fig. 1 is the utility model take-up pulley connection structure schematic diagram;
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Following examples are only be clearly this example of utility model, and the restriction not to embodiment of the present utility model.For those of ordinary skill in the field; can also make other multi-form change or variations on the basis of the following description, and these belong to the utility model spirit apparent change of drawing or variation is still among protection domain of the present utility model.
A kind of take-up pulley connection structure of open cast mine large excavator, comprise: crawler rack, described crawler rack also comprises take-up pulley 1, described take-up pulley 1 center wheel bore fixed conveyor axle 2, the transmission shaft 2 stretching out described take-up pulley 1 both sides is socketed copper sheathing 3 respectively, and described copper sheathing 3 one end is provided with the step 31 of evagination, and described step 31 offsets with described take-up pulley 1 side, described copper sheathing overcoat female connector cartridge type axle bed 4, described axle bed 4 one end and described step 31 offset.
Described take-up pulley 1 two sides are provided with concave station 5, and described step 31 one end is lying in described concave station 5.
In actual use, described axle bed 4 is arranged on the support on described crawler body, described support is also provided with can the pull bar of up-down adjustment, after complete according to above-mentioned Standard, strain described crawler belt and fix, because described step 31 and described take-up pulley 1 offset, described transmission shaft 2 and described copper sheathing 3 area of contact are increased, described transmission shaft 2 now and take-up pulley 1 are a unit design, described transmission shaft 2 rotates and forms relative motion in described axle bed 4, the stressed strong point lengthens, stress condition improves, extend service life, keep in repair also convenient.Reduce the maintenance cost of client.
