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...

Embodiment 1

[0054] Such as Figure 1 to Figure 10 As shown, an advanced support system for anchor net support 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 multiple Two 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 rollers 201 roll when the leading hydraulic support 1 advances; A cylindrical pressure-bearing row 2 is laid between the top beam of the leading hydraulic support 1, so that the pressure can be directly carried in the form of rolling friction, and the leading hydraulic support 1 is pushed from the back through the jack, so that there is no need for pressure relief and re-pressurization, directly Advance like this, can hardly cause any damage ...

Abstract

The invention discloses an advanced supporting system for bolt-mesh supporting. The advanced supporting system comprises a floor supporting body and a roof supporting body. The floor supporting body comprises a bearing block (9), a floor drilling preventing baffle (10) and a guiding plate (11), a vertically-through fixing groove (12) is formed in the middle of the bearing block (9), the guiding plate (11) is arranged in the fixing groove (12), and the floor drilling preventing baffle (10) is an arc plate. The roof supporting body comprises a front top beam protecting plate arranged at the front end of a top beam of an advanced hydraulic support (1), a rear top beam protecting plate arranged at the rear end of the top beam of the advanced hydraulic support (1), and a cylindrical pressure-bearing row (2), and the front top beam protecting plate comprises a plate-type pressure-bearing baffle (4) and a bar-type containing hopper (5). The advanced supporting system is simple in structure, low in cost and easy and convenient to operate.

Description

technical field [0001] The invention relates to the field of advance support for coal mine roadways, in particular to an advance support system and a support method for anchor net support. 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 tech...
