Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 and 2, the field-shaped tool for hoisting and assembling the rotary gear ring of the excavator comprises:

a base 1; the base 1 is a rectangular frame body, two first cross bars and two second cross bars are fixed on the base 1, and the first cross bars and the second cross bars are perpendicular to each other;

two groups of mounting holes; the two groups of mounting holes are arranged at two ends of the base 1 in a line-symmetrical manner by taking the central axis of the base 1 as a symmetry axis, each group of mounting holes comprises two mounting holes, and the mounting holes are blind holes;

four telescopic fixing structures for fixing the rotary gear ring; a telescopic fixing structure is arranged in the mounting hole;

eight hoisting joints 3; the hoisting joint 3 is fixedly arranged on the cross bar.

In this embodiment, the utility model discloses having increased flexible fixed knot and having constructed, having solved the not enough problem of general purpose, flexible fixing device can be adjusted according to the size of the gyration ring gear of different models, can correspond the gyration ring gear of the excavator of multiple model and change, the cost is reduced, and easy and simple to handle, loop wheel machine rethread hoisting joint 3 alright completion to the dismantlement and the installation of gyration ring gear.

Example 2

This example differs from example 1 in that: as shown in fig. 3, 4 and 5, a telescopic fixing structure includes:

an extension spring 5; the first end of the extension spring 5 is fixedly connected with the closed end of the mounting hole, and the extension spring 5 is mounted in the mounting hole;

a connecting rod 4; the first end of the connecting rod 4 is fixedly connected with the second end of the extension spring 5, and the first end of the connecting rod 4 can be slidably arranged in the mounting hole;
