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 explanations of the present invention rather than limitations.
[0023] figure 1 is a schematic diagram of the planar layout of the advanced support in the fully mechanized mining face; figure 2 yes figure 1 Middle A-A sectional view; image 3 yes figure 1 Middle B-B sectional view.
[0024] The installation method of the advance support in the fully mechanized mining face of the present invention divides the installation of each set of advance support into two parts, the front and the back, and uses a multi-purpose vehicle to transport the components of the advance support into place; the installation process includes the following steps:
[0025] Step 1. Lift the beam 2 in the first half and connect it with the column 3 through the pin shaft. After fixing, use a special chain to lift the beam 2 and fix it on the top and side of the roadway in the in...

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 an advance support in a fully mechanized mining face. Background technique [0002] There are 2 groups of air intake advance supports in the fully mechanized mining face of Huangling No. 2 coal mine, and each group is mainly divided into 8 rigid beams, 6 beams, and 12 columns. Use a multi-purpose vehicle in advance to transport the rigid beams, beams, columns and accessories of the advanced support to the advanced support area of the underground belt lane, and then fix the 8 rigid beams on the roof of the roadway according to the designated position, and use wire ropes and manual hoists to move them The 6 beams are suspended and hoisted to a reasonable height, hinged with the rigid beams in sequence, and the moving jack is installed, the pins and bolts are fixed, and the 12 columns are respectively inserted into the telescopic sleeves and hinged togethe...
