Problems solved by technology
[0003] In the past, there were three problems in the installation of the advanced support: first, the rigid parallel beam was too long and heavy, and there were safety hazards in the process of lifting and fixing the roof; Reinstalling the pin shaft requires adjusting the docking point with a chain hoist, and the operation process is cumbersome; third, there is no fixed operating platform for high-altitude docking, and there is no support point protection under the beam, which is not conducive to on-site safety marking

Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with specific embodiments, which are for explanation rather than limitation of the present invention.
[0023] figure 1 It is a schematic diagram of the layout of the advanced support at a fully mechanized mining face; figure 2 Yes figure 1 A-A sectional view in the middle; image 3 Yes figure 1 Section B-B in the middle.
[0024] In the method for installing the advanced support of a fully mechanized mining face of the present invention, the installation of each group of advanced supports is divided into two parts, front and rear, and the components of the advanced support are transported in place by a multifunctional vehicle; the installation process includes the following steps:
[0025] Step 1. Lift the beam 2 of the front half and fix it with the column 3 through a pin. After the fixing is completed, use a special chain to lift and fix the beam 2 on the top of the roadway and the upper part of...

The invention provides an installation method for fore supports of a fully-mechanized mining face. The installation of each group of the fore supports is divided into two parts, the installation method comprises the following steps that step 1, cross beams of the front half part are lifted and then connected and fixed to vertical columns, and after fixing is completed, the top and wall portions ofa roadway which are fixed to the installation area of the front half part are lifted; step 2, rigid beams of the front half part are lifted, and the rigid beams of the front half part and the cross beams of the front half part are fixed in an overlapped mode; step 3,cross beams of the rear half part are lifted and then connected and fixed to the vertical columns, and after fixing is completed, the top and wall portions of a roadway which are fixed to the installation area of the rear half part are lifted; and step 4, then rigid beams of the rear half part are fixed to the cross beams of the rear half part in an overlapped mode, and the rigid beams of the front half part and the rigid beams of the rear half part are connected in a butting mode. According to the installation method for thefore supports of the fully-mechanized mining face, the cross beams and the vertical columns are used as a butting platform of the rigid beams, the processes of aerial hoisting and aerial equipment butting of the rigid beams are reduced, the work efficiency is improved, and the construction safety is ensured.
Description
Technical field [0001] The invention belongs to the technical field of coal mines and relates to a method for installing a leading support in a fully mechanized mining face. Background technique [0002] Huangling No. 2 Coal Mine's fully mechanized mining face has two sets of air intake advanced supports. Each group is mainly divided into 8 rigid beams, 6 cross beams, 12 uprights, etc. In the past, in the installation of advanced supports at fully mechanized mining faces, Use a multifunctional vehicle in advance to transport the rigid beams, beams, columns and various accessories of the leading support to the leading support area of the underground belt roadway, and then fix the 8 rigid beams on the roof of the roadway at designated positions, and use wire ropes and manual hoists to The 6 beams are suspended to a reasonable height, and the rigid beams are hinged in order, and the jack is installed, the pins and bolts are installed, the 12 columns are inserted into the telescopi...
