CN219386472U - A bellows buffer mechanism for the horizontal pull plate of the electric bucket door - Google Patents

Abstract

The utility model relates to a bellows buffer mechanism for a horizontal pull plate of an electric shovel door, comprising an electric shovel door, a crossbeam, a horizontal pull plate, a door plug and a buffer mechanism. It is characterized in that the buffer mechanism includes a U-shaped rubber bellows and a connecting component. The connecting component is composed of an upper fixing frame, a lower fixing frame, an upper galvanized pipe, a lower connecting pipe and a regulating valve. The center of the fixed frame is provided with a central through hole, and the two ends are respectively provided with bolt holes. The lower end of the upper galvanized pipe is fixed on the upper part of the lower fixed frame; the lower connecting pipe and the upper galvanized pipe are fixedly connected to the lower part of the lower fixed frame, and the upper part of the U-shaped rubber bellows is fixedly connected to the outside of the lower galvanized pipe through clips. The bellows buffer mechanism of the utility model can reduce the impact of the horizontal pull plate on the bucket, prolong the service life of the horizontal pull plate, and facilitate replacement at the same time.

Description

A bellows buffer mechanism for the horizontal pull plate of the electric bucket door

technical field

The utility model belongs to the technical field of electric shovels, in particular to a bellows buffer mechanism for a horizontal pull plate of a bucket door of an electric shovel.

Background technique

The electric shovel bucket door horizontal pull plate buffer mechanism generally uses a solid or hollow rubber ring as a buffer shock absorber. The electric shovel needs to frequently open and close the electric shovel bucket door to unload during the operation process. affect the service life of components.

Contents of the invention

The purpose of this utility model is to solve the problem that the rubber ring buffer is not durable, and provide a bellows buffer mechanism for the horizontal pull plate of the electric bucket door that can reduce the impact of the pull plate on the bucket and prolong the service life of the pull plate.

The utility model is realized through the following technical solutions:

The utility model relates to a bellows buffer mechanism for the horizontal pull plate of the electric shovel door, which includes the electric shovel bucket and the electric shovel door, the crossbeam, the horizontal pull plate, the door plug and the buffer mechanism on the crossbeam arranged on the electric shovel door, and is characterized in that the buffer mechanism includes a U-shaped rubber bellows and a connecting component. The connecting component is composed of an upper fixing frame, a lower fixing frame, an upper galvanized pipe, a lower connecting pipe and a regulating valve. Bolt holes are concentrically opened at both ends of the upper fixing frame and the lower fixing frame respectively. The lower end of the upper galvanized pipe is fixed on the lower fixing frame and communicates with the central through hole of the lower fixing frame. The lower end passes through the central through hole of the upper fixing frame and is placed on the upper part of the upper fixing frame. Galvanize the outside of the pipe.

Compared with the prior art, the utility model has the advantages that: the bellows buffer mechanism of the utility model can reduce the impact of the horizontal tie plate on the bucket, prolong the service life of the horizontal tie plate, and facilitate replacement at the same time.

Description of drawings

Fig. 1 is a structural schematic diagram of the utility model installed on the bucket door of an electric shovel.

Fig. 2 is a structural schematic diagram of the bellows buffer mechanism of the present invention.

Implementation

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1-2, a bellows buffer mechanism for the electric shovel door horizontal pull plate of the present utility model includes an electric shovel bucket and an electric shovel door 1, a beam 6 arranged on the electric shovel door, a horizontal pull plate 4, a door plug 5, and a buffer mechanism 3 on the cross beam 6. It is characterized in that the buffer mechanism 3 includes a U-shaped rubber bellows 31 and a connecting assembly. Regulating valve 37 is made up of, and the center of upper fixing frame 35 and lower fixing frame 34 is concentrically provided with a central through hole, and the two ends of upper fixing frame 35 and lower fixing frame 34 are respectively concentrically provided with bolt holes. The diameter of the lower connecting pipe 33 is greater than the diameter of the upper galvanized pipe 36, and is fixedly connected with the upper galvanized pipe 36 to the bottom of the lower fixed frame 34, and the top of the U-shaped rubber bellows 31 is fixedly connected to the outside of the lower galvanized pipe 33 by clips 32, and 2 is a door rope among the figures.

The bellows buffer mechanism of the present utility model is installed on the crossbeam 6 of the electric shovel bucket door through bolts. During operation, the horizontal pull plate 4 is lifted to hit the bellows buffer mechanism, and the stroke of the bellows buffer mechanism is controlled by adjusting the opening of the regulating valve 37. If the shock absorber fails, replace the shock absorber again.

In the description of the present utility model, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper" and "lower" are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood in specific situations.
