Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] like Figure 1 to Figure 4As shown, the fully loaded self-moving anti-falling anti-skid hydraulic support includes a main top beam 1, an auxiliary top beam 2, a top beam connecting device 3, a main base 4, an auxiliary base 5, a column 6, a horizontal connecting device 7 and a moving jack 8 .

[0038] The main top beam 1 is arranged at the middle position of the whole full load self-moving anti-fall anti-skid hydraulic support, and its front end is provided with a front telescopic beam.

[0039] Described sub-top beam 2 is arranged as two pieces, symmetrically arranged on the left and right sides of main top beam 1, and the length dimension of sub-top beam 2 top plate is the same as the length dimension of main top beam 1, and the width dimension is smaller than that of main top beam 1 Width dimension.

[0040] The roof beam connecting device 3 is arranged be...

Abstract

The invention discloses a full-load self-moving anti-falling and anti-slip hydraulic support, which comprises a main top beam (1), an auxiliary top beam (2), a top beam connecting device (3), a main base (4), an auxiliary base (5), Upright column (6), horizontal connecting device (7) and moving jack (8), the horizontal connecting device includes an upper connecting mechanism (71) and a lower connecting mechanism (72), and the two auxiliary top beams are fixedly connected through the upper connecting mechanism , the two auxiliary bases are fixedly connected through the lower connecting mechanism; at least two pieces of moving jacks are provided, one end of one piece is hinged to the main top beam, the other end is hinged to the upper connecting mechanism, one end of the other piece is hinged to the main base, and the other end Hinged to the lower connection mechanism. The support area of ​​the bottom plate of the self-moving anti-fall and anti-slip hydraulic support with full load is large, and the support effect is good; when the frame is moved, the auxiliary top beam and the auxiliary base move synchronously, which is not easy to deviate, and the overall stability is good; The damage of the roof is small, and the integrity of the roof can be better maintained.

Description

technical field [0001] The invention relates to a hydraulic support, in particular to a fully loaded self-moving anti-falling and anti-slip hydraulic support, which belongs to the technical field of hydraulic supports. Background technique [0002] The hydraulic support is the supporting equipment of the fully mechanized mining face. Its main function is to support the roof of the stope, maintain a safe working space, and push the mining and transportation equipment on the working face. The hydraulic support is powered by high-pressure liquid, and through the expansion and contraction of various power cylinders, Make the bracket complete various actions such as raising, landing, walking and pushing the conveyor, so that the bracket can repeatedly support, move forward and adjust with the continuous advancement of the working surface. [0003] At present, the support used in coal mines in my country generally adopts four-bar linkage mechanism, double-column or four-column cov...
