Abstract

The invention discloses a rapid hydraulic control alignment device of comprehensive mechanized coal mining face retracement equipment. The rapid hydraulic control alignment device comprises a bottom plate, wherein two rails for laying a flat car are fixedly connected with the bottom plate; jack fixed seats which correspond to each other in the front-rear direction are respectively fixedly connected with left and right sides of the rails; hydraulic pressure alignment jacks which are laterally arranged are fixedly connected with the jack fixed seats; the free ends of expansion links of the hydraulic pressure alignment jacks inward extend to the rails; the free ends of the expansion links of the hydraulic pressure alignment jacks are connected with ejecting blocks; the ejecting blocks are articulated with the free ends of the expansion links of the hydraulic pressure alignment jacks; the jack fixed seats are vertically arranged. The operation process of the device comprises the following steps: firstly pulling a hydraulic support onto the flat car, adjusting the position of the hydraulic support on the flat car through the matching of four hydraulic pressure alignment jacks A, B, C and D, ensuring that the gravity center of the hydraulic support coincides with the gravity center of the flat core, sealing the flat car, and then accomplishing loading and alignment.

Description

technical field [0001] The invention relates to a mining device, in particular to a quick hydraulic control adjustment device for retraction equipment of a fully mechanized mining face. Background technique [0002] Due to the influence of changes in the geological conditions of the coal mine, the retraction equipment conditions of the fully mechanized mining face are different. Some equipment is loaded through the climbing frame device. It is not easy to adjust the center of gravity for irregular objects and center of gravity shifting parts, resulting in vehicle deviation and overturning. accidents, and even personal safety accidents. The center of gravity of the vehicle needs to be greatly adjusted from multiple directions and angles. At present, the method of chain hoist manual adjustment is mostly used, but this process has the disadvantage of many procedures, the construction personnel are close to the parts, there are potential safety hazards, and the efficiency is lo...
