Problems solved by technology

However, the sliding friction generated by this method of moving the frame will seriously affect the service life of the frame, and will bring defects such as large forward resistance and extremely unstable walking, which will easily cause harm to the safety of roadway personnel.
[0003] At the same time, for all the current traditional advanced supports, the structure of pushing and mo

Embodiment 1

[0055] Such as Figure 1 to Figure 10 As shown, an improved advanced support body includes a roof support body and a bottom plate support body. The roof support body includes an advanced hydraulic support 1 and a cylindrical pressure-bearing row 2. The cylindrical pressure-bearing row 2 is composed of a plurality of cylindrical rollers 201 are formed in series in sequence, and the cylindrical pressure-bearing row 2 is arranged between the top beam of the leading hydraulic support 1 and the roadway roof 3, and the cylindrical roller 201 rolls when the leading hydraulic support 1 advances; when the roadway roof 3 and the leading hydraulic support A cylindrical pressure-bearing row 2 is laid between the top beams of 1, so that the pressure can be directly carried in the form of rolling friction, and the leading hydraulic support 1 can be pushed from behind through the jack, so that there is no need to release and repressurize, and it can be pushed forward directly in this way , w...

Abstract

The invention discloses an improved advance support body. The improved advance support body comprises a roof support body and a floor support body; the roof support body comprises an advanced hydraulic support (1), a cylindrical pressure-bearing array (2) and a lubricating brush (8), wherein the lubricating brush (8) comprises a fixing rod (801), supporting rods (802), an oil tank (803) and a cylindrical brush (804); the floor support body comprises a bearing block (9), an anti-drilling bottom baffle plate (10) and a guide plate (11); the bearing block (9) is connected with the front end of a base of the advanced hydraulic support (1); a fixed groove (12) which penetrates vertically is formed in the middle of the bearing block (9). The improved advance support body disclosed by the invention has a simple structure, and is reliable and practical.

Description

technical field [0001] The invention relates to the field of advance support of coal mine roadways, in particular to an improved advance support body and a use method. Background technique [0002] With the continuous improvement of the degree of mechanization of fully mechanized mining faces, under suitable geological conditions, major coal mines in my country have gradually used advanced support hydraulic supports. According to structural characteristics, advanced supports can be divided into: large mining height four-link advanced support hydraulic pressure Supports, self-moving hydraulic supports for advanced support, hydraulic supports for straddle-type advanced supports, and crawler-type advanced support hydraulic supports. The first three kinds of advance support hydraulic supports all need to take actions such as lowering, pulling (or pushing), lifting, adjusting, and then lowering and lifting when moving the frame. That is to say, there are technical defects in repe...
