Problems solved by technology

[0003] 1. The bottom of the cylinder is the installation position of the stroke sensor, and it is also the installation structure position of the jack and the bracket. The combination of the diversity of the two brings a variety of cylinder bottom specifications, which brings a great burden to the manufacturer
[0004] 2. Due to the structure of the stroke sensor, the hole at the bottom of the cylinder used to install the stroke sensor is often a stepped hole. The size is small and the stroke is long, the processing is difficult, and the processing accuracy is difficult to guarantee. It is difficult to guarantee the processing while requiring special tools to increase the cost. Accuracy also affects the performance of the jack

Abstract

The invention provides a modularized cylinder bottom which comprises a main body module and a sensor module, wherein the sensor module is fixedly connected with the main body module; the sensor moduleis provided with a sensor through hole, is used for mounting a stroke sensor and can be changed into a different sensor module according to different stroke sensor model numbers; the main body moduleand the sensor module are assembled and fixed to jointly form the cylinder bottom of a jack; and different main body modules can be selected according to different bracket connecting manners. On theother hand, the invention provides a jack for a hydraulic bracket and a preparation technology of the cylinder bottom.

Description

technical field [0001] The invention relates to the field of jacking devices, in particular to a hydraulic support jack, a modular cylinder bottom and a preparation process for the cylinder bottom. Background technique [0002] With the development of technology and the process of automation, the column and jack, an important part of the mine hydraulic support and the power actuator, will also develop accordingly, and the addition of the stroke sensor will make the jack of the mine hydraulic support automatic. However, travel sensors of different specifications have different installation structures, and when combined with a variety of jacks for supports, it also brings new problems: [0003] 1. The cylinder bottom is the installation position of the stroke sensor, and also the installation structure position of the jack and the bracket. The combination of the diversity of the two brings a variety of cylinder bottom specifications, which brings a great burden to the manufact...
