Problems solved by technology

[0003] In the above two support methods, there are disadvantages such as high labor intensity, complicated operation, long time consumption, and poor adaptability to the roof. At the same time, when workers manually build temporary supports, there is still the phenomenon of empty roof operation, which is quite dangerous. This is also an important reason for frequent accidents in coal mines, which seriously affects the mining efficiency of mines and the safety of workers.

Abstract

The invention provides an advance support, an advance support set and an advance supporting device. The advance support comprises bases, support cylinders, a top beam and guard boards. One end of each support cylinder is connected to the corresponding base. The other end of each support cylinder is connected to the bottom of the top beam. The advance support further comprises support posts including first posts and second posts. One end of each second post is telescopically mounted at one end of the corresponding first post. The other end of each first post is fixedly connected to the corresponding base. The other end of each second post is fixedly connected to the top beam. The second posts support the top beam along with telescoping of the support cylinders. The invention further provides an advance support set and an advance supporting device. Repeated supporting with the advance support set can be reduced, damage of a top plate can be reduced, speed of moving the advance support is increased, labor intensity is reduced for workers, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of underground support in coal mines, in particular to an advanced support bracket, an advanced support bracket group and an advanced support bracket device. Background technique [0002] At present, in mine production support, temporary support is generally built in the empty roof area 2m to 3m in front of the tunneling head, and the following two methods are mostly used: one is artificial extension beam construction, and the other is safety point column temporary support. support. [0003] In the above two support methods, there are disadvantages such as high labor intensity, complicated operation, long time consumption, and poor adaptability to the roof. At the same time, when workers manually build temporary supports, there is still the phenomenon of empty roof operation, which is quite dangerous. This is also an important reason for the frequent occurrence of accidents in coal mines, which has seriously affected...
