specific Embodiment approach

[0024] Specific implementation methods: such as figure 1 As shown, a fully-mechanized track cyclically moving forward advance support system includes an advance support 2 arranged in a coal mine roadway, and a multifunctional handling device 1 for moving the advance support 2 . The present invention adopts a kind of advanced support to be arranged along the roadway to realize the support of the roadway. The distance between the front and back of each two sets of advanced support 2 is 200mm (the distance can be increased according to the support strength), and the distance between the last support 2 and the front edge of the end is 400mm. , a group of end and tail frames are arranged behind the leading support 2 for supporting the end roadway. The center-to-center distance between the left and right sides of each bracket 2 is 780-2580 mm, the inner profile of the bracket 2 is 460-2262 mm, and the outer profile is 1200-3000 mm. like image 3 As shown, the column 5 of the supp...

Abstract

The invention relates to coal mine equipment, in particular to a shoring device arranged at a combined mining work face end and specifically to a combined mining rail crossheading circulating forward type forepoling system. The combined mining rail crossheading circulating forward type forepoling system comprises a forepoling in a coal mine roadway and a multifunctional carrier for transporting the forepoling, wherein a cable reel device is arranged in the front of the carrier, and the forepoling is arranged along the roadway so as to forepole a rail crossheading. A forepoling adjusting jack is distributed in the center of a top beam in a cross mode and connected by a steering cartridge to prevent a forepoling from being inclined in working and moving processes, so that the stability of the forepoling in a lifting process is guaranteed and requirements that the width of the forepoling is adapted to width change of the roadway and the carrier can pass through smoothly are met. The forepoling can be moved through the multifunctional carrier, and therefore, the combined mining rail crossheading circulating forward type forepoling system is novel in forepoling moving way and is safe and reliable, the forepoling moving efficiency is increased, and meanwhile, the labor intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to coal mine equipment, in particular to a supporting device at the end of a fully mechanized mining face, in particular to a fully mechanized mining track moving forward circularly along a groove type advance supporting system. Background technique [0002] At present, in some fully mechanized mines, under the condition of low mine pressure and complete roof, the two lanes of the working face are supported by the advance supports along the groove. It needs to be pulled once, and each pulling process requires the support to be lowered and raised once, forming a sequential and repeated support for the roof in the support area, which greatly damages the integrity of the roof, thus affecting the working surface. Shun Tiao's safety is threatened. In some coal mines, the buried depth of the coal seam is large, the pressure of the mine is severe, the geological structure of the coal seam is complex, there are many faults, and the roof...
