Abstract
The utility model relates to a universal supporting column which comprises a monomer hydraulic prop and a supporting plate arranged at the top end of the hydraulic prop, wherein the top end of the hydraulic prop is movably connected with the supporting plate. By adopting the universal supporting column, the universal joint movable column sleeve is sleeved on the monomer hydraulic prop, and the connecting pin is connected with the universal joint movable column cap, so that the utility model can be flexibly suitable for uncertainty of the inclined surface or the uneven surface of the coal bed and provides a safer environment for construction for workers, and the universal joint can be reused for times, is convenient to use and can flexibly move.
Description
Technical field
The utility model belongs to the coal mining suspension device, cooperates hydraulic prop to use, and relates in particular to that big gun is adopted, the coal mining suspension device of conventional face.
Background technology
Hydraulic prop can be adopted for general big gun, conventional face coal mining supporting roof uses, and it can reliably and effectively support and control the top board of work plane, isolates the goaf, prevents that spoil from entering stope and advancing conveyer.Equipment and technology that big gun is adopted are simple, and complex geological conditions is good at adapting to, and still account for 60% of total output in China at present.But it is big that big gun is adopted labour intensity, especially under complex geological conditions, top board tilts, uneven, need constantly to adjust the support angle of hydraulic prop and back timber, back timber and hydraulic prop are and contact or the line contact, very easily cause back timber slippage or post pawl to lose avalanche because of stressed concentrating, and occur security incident easily.
In recent years, the development of the development work of China's hydraulic prop equipment is very fast, and from relying on import basically, develop into design voluntarily, make voluntarily, and various in style, multiple functional, reliable in quality.But large-scale supporting frame moves inconvenience, and weight is big, and the surface irregularity in coal seam, and traditional support apparatus can not play support action very easily, needs the workman to utilize some cushion blocks to keep supporting frame balance, and operation is inconvenience particularly, and safety factor is not high.
The utility model content
The purpose of this utility model provides a kind of universal supporting column cap that can adapt to the scraggly or inclination aspect in coal seam, cooperates the safe and efficient use of hydraulic prop.
In order to achieve the above object by the following technical solutions: comprising hydraulic prop and be arranged on the gripper shoe on hydraulic prop top, is active link between hydraulic prop top and the gripper shoe.
Described active link is hinged.
The described hinged universal joint connection that is.
Described universal joint is the column type universal joint.
Described universal joint is a rzeppa joint.
Adopt the utility model, on hydraulic prop, apply mechanically the movable column sleeve of universal joint, connect the movable column cap of universal joint by connecting pin and can be applicable to seam inclination face or scraggly aspect uncertainty flexibly, provide safer environment to workman's construction, universal joint can be repeatedly used, easy to use, move flexibly.

The specific embodiment
Shown in Fig. 1,2,3,4,5,6,7, a kind of universal support post that can adapt to the scraggly or inclination aspect in coal seam, comprise hydraulic prop 4 and be arranged on the gripper shoe 5 on hydraulic prop top, hinged between hydraulic prop 4 tops and the gripper shoe 5 by the column type universal joint.Described hinged for being provided with the column type universal joint in the hydraulic prop upper end.Described column type universal joint comprises the movable column cap 3 of universal joint, the movable column sleeve 1 of universal joint, and the movable column cap of universal joint is fixed on hydraulic prop, and the movable column sleeve of universal joint is connected by the movable column cap of universal joint connecting pin 2 and universal joint.
Embodiment 2
A kind of universal support post comprises hydraulic prop and is arranged on the gripper shoe on hydraulic prop top, is connected by rzeppa joint between hydraulic prop top and the gripper shoe.
