Embodiment Construction

[0040] 1. The universal bracket (1.0) is composed of a roller frame and a bracket.

[0041] Roller frame is assembled into by hanging wheel (1.1), supporting wheel (1.2), and connecting support (1.3) with axle, bearing, see Fig. 6, Fig. 7.

[0042] The bracket is composed of two or more non-parallel longitudinal beams (1.4) and connecting rods (1.5) hinged with pins. Longitudinal beams (1.4) with different lengths respectively form brackets with different lengths, and the two longitudinal beams (1.4) can move up and down and rotate mutually, as shown in Fig. 3, Fig. 5 and Fig. 15 .

[0043] Connecting support (1.3) is connected with longitudinal beam (1.4) with pin shaft slotted hole, see Fig. 6, Fig. 7.

[0044] Top beam (6) is contained between suspension wheel (1.1) and supporting wheel (1.2), see Fig. 5, Fig. 6.

[0045] Therefore, the roller frame and the bracket can move up and down and rotate each other, the top beam (6) can realize rolling displacement between the su...

Abstract

The invention relates to an assembled hanging hydraulic support with a universal upper holder and a lower hanging beam, comprising a top beam, a step-type hydraulic cylinder, a hydraulic prop, a step size adjusting location baffle, the universal upper holder, the lower hanging beam and a picking flat car, characterized in that the universal upper holder comprises a roller holder and a holder, while the lower hanging beam comprises a beam, a hanger rod and a leg ring, and the picking flat car is equipped with a lifting tool capable of rotating, and the hydraulic prop is connected with the top beam via a three-axis and four-rope suspension second ball-hole, wherein the prop is lifted and moves in step with a drag conveyer. The invention has the advantages of simple structure, easy production and convenient assembling and repairing.

Description

technical field [0001] The invention relates to a supporting device for coal mine safety production, in particular to a combined suspension hydraulic support with a universal upper bracket and a lower hanging beam. technical background [0002] At present, although many known hydraulic supports have made a significant contribution to the safe production of coal mines, some have poor integrity, are easy to dump, and have a single function; some have complex structures and high manufacturing costs; defect. Presently known hydraulic supports do not have universal upper brackets and lower hanging beams, and do not have functions such as carrying and moving slides at the same time. Contents of the invention [0003] The object of the present invention is to provide a combined suspension hydraulic support with a universal upper bracket and a lower hanging beam, which not only has low processing and manufacturing costs, good integrity, and does not tip over, but also has multipl...
