Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Shown in Figures 1 and 2 is the end bracket for the lower end of the fully mechanized caving surface of the present invention, which is a simple two-frame group type, consisting of a left frame, a right frame, an anti-fall jack between the left and right frames, and a hydraulic circuit .

[0024] ①Left frame: It is composed of three-section top beams, three-section bases, and three columns correspondingly hinged between them. The three-section top beam is: the left front top beam (3), the left middle top beam (5), the left rear top beam (7); the three-section base: the left front base (23), the left middle base (19), the left rear base (15 ); Three columns: front column (30), center column (32), rear column (33).

[0025] The three-section top beams are sequentially hinged. The front end of the left front top beam (3) is hinged with the left f...

Abstract

The invention relates to synthesizing discharging face end hydraulic support. Two of them are formed a set. It is made up of left support, right support, falling preventing jack, and hydraulic circuit. The left and right support are made up of three top beams, three bases, and three columns all of with are divided into front, middle, and back. The three top beams are hinged orderly. The front top beam is hinged to canopy guard front beam and its jack. The back top beam is hinged to caving shield. The three bases are hinged orderly. It is adopted front back joining among the bases. The front base is connected to loading mechanism. The falling preventing jack is hinged between the top beams and connecting rod. The distance between the front and middle columns, middle and back columns are respectively adapted to the distance that the width of the front back scraper conveyor plus forward lead step pitch. The left support base is set side jack. The invention can realize end head supporting mechanization, reduce manual labor, increase ahead speed. Its structure is simple; weight is light; the support moving is convenient.

Description

Technical field [0001] The invention relates to support equipment for fully mechanized top-coal caving working face in underground coal mines, in particular, it is suitable for the end of fully mechanized caving working face and is matched with equipment such as high-power and large-capacity scraper conveyor and self-moving reloading machine. Hydraulic support at the end of fully mechanized caving face. Background technique [0002] The end of the fully mechanized caving face is the intersection of the working face and the mining roadway. Under the action of various supporting pressures, the surrounding rock in the end area is most affected by mining. The focus of maintenance is also the difficulty of roof management. Especially at the lower end, there are many equipments arranged in the area, including front and rear scraper conveyors and self-moving transfer machines, which are not only the handover point of mining and transportation equipment, but also the throat of pede...
