Problems solved by technology

[0003] The purpose of the present invention is to provide a stepping self-moving support, which solves the problem that after the roadheader has driven for a certain distance, it needs to stop advancing and continue to cut after artificial support, resulting in too little effective footage time and a lot of working time. Waste and other issues, for the support of the roof of the roadway, the support of the side, the advance temporary support and the function of stepping self-moving, the support can greatly improve the working efficiency of the roadheader and temporary support, and greatly reduce the work intensity of the operator. improve security

Embodiment Construction

[0020] Such as figure 1 , figure 2 , image 3 As shown, the support is composed of several sub-supports 1, and the sub-supports 1 are connected by the frame-moving cylinders 2, and the sub-supports 1 are moved by the action of the frame-moving cylinders 2. Each sub-support is made up of main frame 3, top support frame 4, top support oil cylinder 5, side support frame 6, side support oil cylinder 7. The main frame 3 is a gantry frame structure, the top of the main frame 3 is provided with a slideway and an oil cylinder mounting seat, the two sides of the main frame 3 are provided with a slideway and an oil cylinder mounting seat 8, and the bottom of the main frame 3 is a walking shoe 9. Top support frame 4 is made up of crossbeam I10, leaf spring I11, top support plate 12, slide frame I13, top support frame 4 is installed on the top of main frame 3 by slideway, top support frame 4 and main frame 3 are supported by top support oil cylinder 5 Connected to each other, the carr...

Abstract

The invention relates to coal mine roadway support machinery, in particular to a walking support which can realize temporary support and walking functions of a roadway, can be used for the temporary support of a roadway head and can be matched with a heading machine to finish the parallel operation of heading and support. The support comprises at least two branch supports, wherein the branch supports are connected by moving cylinders; a top bracing frame of each branch support is mounted on the upper part of a main frame by a slideway, the top bracing frame is connected with the main frame by a top support cylinder, lateral bracing frames are mounted at both sides of the main frame by slideways, and the lateral bracing frames are connected with the main frame by lateral support cylinders. Because of the telescopic control of the cylinders, the complete set of support can realize walking forwards or backwards; and each branch support is provided with a top bracing plate and lateral bracing plates, thereby supporting the roof and the lateral walls of the roadway. The invention can solve the problems that the effective footage time of the heading machine is too little, a large amount of working time is wasted and the like in the prior art.

Description

technical field [0001] The invention relates to coal mine roadway support machinery, specifically a stepping self-moving support, which can realize the temporary support of the roadway and the function of stepping self-moving, and can be used for the temporary support of the tunneling face, and can be realized in cooperation with the roadheader Excavation, protection parallel operation. Background technique [0002] At present, the working efficiency of roadway excavation is extremely low. The main reason is that due to the poor geological conditions of coal mines in my country, the space-time top distance of roadway excavation should not be too large. Therefore, after the roadheader has excavated a certain distance, it needs to stop advancing and continue to cut after manual support is required. The real footage time is only 30% of the total working time, resulting in too little effective footage time and a lot of work time being wasted. . Moreover, the manual labor inten...
