Embodiment

[0016] Such as figure 1 As shown, the mechanism used to limit the central part of the rear frame includes a disc-shaped positioning disc 1. The end surface of the positioning disc 1 is provided with a connecting shaft 2, and the axis of the connecting shaft 2 and the positioning disc 1 The axes coincide. The outer wall of the connecting shaft 2 is sleeved with a rotating sleeve 5. The rotating sleeve 5 is fixed on the outer wall of the connecting shaft 2. The outer wall of the rotating sleeve 5 is recessed to form a groove 4, and the groove 4 and the rotating sleeve 5 are far away from the positioning disk The end faces of 1 are connected. The positioning disc 1 is in contact with the central part of the rear frame, and the handle is extended into the groove 4 of the rotating sleeve 5 to drive the rotating sleeve 5 to rotate. The rotating sleeve 5 is fixed with the connecting shaft 2 and finally drives the connecting shaft 2 Move, so that the positioning plate 1 and the rear f...

Abstract

The invention discloses a mechanism for limiting the central position of a rear frame. The mechanism comprises a disc-shaped positioning plate, a connecting shaft is arranged on the end face of the positioning plate, the axis of the connecting shaft coincides with the axis of the positioning plate, a rotating sleeve is fixedly sleeved on the outer wall of the connecting shaft, the outer wall of the rotating sleeve is concaved inwards to form a groove, and the end face of the rotating sleeve, which is far away from the positioning plate, is communicated with the groove. The mechanism is simple in structure, convenient to use and capable of solving the problem of deformation of the central position of the rear frame, so that the rear frame is positioned according to preset design during assembly, the assembling effect is good, and problems of a loader due to the rear frame can be avoided during the follow-up usage.

Description

Technical field [0001] The invention relates to a limiting mechanism, in particular to a mechanism for limiting the central part of a rear frame, belonging to the mechanical field. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in roads, railways, construction, hydropower, ports, mines and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime and coal, and can also be used for ore , Hard soil, etc. for light shovel and digging operations. Different auxiliary working devices can also be used for bulldozing, lifting and loading and unloading of other materials such as wood. In road construction, especially in the construction of high-grade highways, loaders are used for filling and excavating roadbed works, asphalt mixtures and aggregate and loading of cement concrete yards. In addition, it can also carry out operations such as pushing soil, leveling the ground, and pulling other machin...
