SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a novel square guide wheel seat of an electric shovel, which solves the problem that the traditional square guide wheel seat is difficult to assemble when the square seat transversely counter shaft because the maximum gap requirement is 0.3 mm; the guide wheel shaft and the square seat are fixed and are oilless, the guide wheel shaft and the square seat run continuously, the shaft and the hole are clamped easily, and the guide wheel or the guide wheel shaft needs to be replaced and cannot be disassembled, so that the difficulty in daily maintenance is brought, and the fault downtime of the electric shovel is prolonged.

In order to realize the purpose, the utility model discloses a technical scheme be:

the utility model provides a novel electric shovel guide wheel square seat, includes square seat body, its characterized in that, square seat body includes square seat convex surface and square seat platform, square seat convex surface and square seat platform integrated into one piece, be equipped with the through-hole in the middle of the square seat body, the through-hole runs through square seat convex surface and square seat platform, be equipped with the locating hole on the square seat convex surface, the locating hole runs through square seat convex surface, through-hole and locating hole mutually perpendicular, the square seat body prolongs the axial and is equipped with the elastic groove, the elastic groove runs through square seat body, this elastic groove and through-hole intercommunication, and skew locating hole.

Preferably, the square seat platform is arranged in the middle of one end face of the convex face of the square seat.

Preferably, the axial cross section formed by the convex surface of the square seat and the square seat platform is T-shaped.

Preferably, the convex surface of the square seat is a cube or a cuboid, and the square seat platform is a cylinder.

Preferably, the elastic groove is positioned in the middle of the axial side end face of the convex surface of the square seat.

The utility model has the advantages that: the utility model solves the problem that the traditional square seat of the guide wheel is difficult to assemble when the square seat is transversely aligned because the maximum clearance requirement is 0.3 mm; the guide wheel shaft and the square seat are fixed and are oilless, the guide wheel shaft and the square seat run continuously, the shaft and the hole are clamped easily, and the guide wheel or the guide wheel shaft needs to be replaced and cannot be disassembled, so that the difficulty in daily maintenance is brought, and the fault downtime of the electric shovel is prolonged.

Drawings

FIG. 1 is a front view of the present invention;

FIG. 2 is a right side view of the present invention;

in the figure: 1. the square seat comprises a square seat convex surface, 2 a square seat stand, 3 an elastic groove, 4 a through hole, 5 a positioning hole, 6 and a square seat body.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The novel square electric shovel guide wheel seat shown in the figures 1-2 comprises a square seat body 6 and is characterized in that the square seat body 6 comprises a square seat convex surface 1 and a square seat platform 2, the square seat convex surface 1 and the square seat platform 2 are integrally formed, a through hole 4 is formed in the middle of the square seat body 6, the through hole 4 penetrates through the square seat convex surface 1 and the square seat platform 2, a positioning hole 5 is formed in the square seat convex surface 1, the positioning hole 5 penetrates through the square seat convex surface 1, the through hole 4 is perpendicular to the positioning hole 5, an elastic groove 3 is axially arranged in the square seat body 6, the elastic groove 3 penetrates through the square seat body 6, the elastic groove 3 is communicated with the through hole 4, and the positioning hole 5 deviates.

Preferably, the square base platform 2 is arranged right in the middle of one end face of the convex surface 1 of the square base; the axial cross section formed by the convex surface 1 of the square seat and the square seat platform 2 is T-shaped; the square seat convex surface 1 is a cube or a cuboid, and the square seat stand 2 is a cylinder; the elastic groove 3 is positioned in the middle of the axial end surface of one side of the convex surface 1 of the square seat.

The utility model is realized in such a way that the guide wheel is the main part of the electric shovel walking, the guide wheel is connected with other parts through the guide wheel shaft to cooperate when being assembled, the guide wheel is connected with the guide wheel shaft and is blocked by one part to prevent the guide wheel from being separated from the guide wheel shaft when the electric shovel walks in a rolling way, the novel square seat of the electric shovel guide wheel has the function, the guide wheel shaft is provided with a through hole when being assembled, the through hole is matched with a positioning hole 5 arranged on the convex surface 1 of the square seat, the positioning fixed connection is formed by bolts, the traditional square seat is not provided with an elastic groove 3, the axial direction is a closed form, because the electric shovel generally operates in a high-temperature dust environment and humid air in the field and is free of oil lubrication, the guide wheel shaft is in clearance fit with the through hole 4 of the square seat body 6 and has a hole reference, the maximum clearance is 0.3mm, therefore, the guide wheel shaft can be prevented from rotating, and the square seat is difficult to assemble when being transversely aligned because the maximum gap requirement is 0.3 mm; guide shaft and square seat body 6 are fixed, oil-free lubrication, and continuous operation easily leads to axle and hole card to die, just can't decompose the dismantlement when need to change guide wheel or guide shaft, can bring the difficulty for daily maintenance like this, has prolonged electric shovel fault down time, however the utility model discloses an elastic groove 3 can be adjusted the clearance of guide shaft and square seat body 6's through the 3 use tools in elastic groove in certain within range in the assembly with dismantling, can effectual solution assembly and the problem of dismantling on like this.
