specific Embodiment approach

[0031] The preferred embodiment of the handrail used for the large-inclination hydraulic support of the present invention is:

[0032] A fixing piece is arranged on the column of the large-inclination hydraulic support, and a bus handrail is connected to the fixing piece.

[0033] The fixing member is a hoop pressed from a steel plate, and the hoop is fixed on the column by bolts and nuts.

[0034] The hoop includes two bent plates, and a pressing block is provided at the joint of the two bent plates. The bent plate and the pressing block are connected and fixed by bolts and nuts. The pressing block is fixed with a nylon belt, and the nylon belt is connected to the bus handrail. connect.

[0035] The bent plate is formed by direct pressing of 4mm thick steel plate, and the briquetting block is formed by cutting steel pipe.

[0036] The fixing part is a fixing seat or a valve backing plate welded on the column, and the fixing seat or the valve backing plate is connected with ...

specific Embodiment

[0038] like Figure 3a , Figure 3b As shown, a hoop 2 is provided on the column 1 of the large-inclination hydraulic support, and a bus handrail 5 is provided on the hoop 2, and the hoop pressed by a steel plate is fixed on the column. The fixing method adopts bolts and nuts, all structures do not need to be welded, and the processing is convenient. Bus handrails can be purchased in the market with high standardization and low cost.

[0039] like Figure 4 As shown, the column clamp of the matching bus handrail includes a bent plate 6 and a pressing block 7, and the bent plate adopts a 4mm thick steel plate, which is directly pressed and formed. Two pieces of bent plates are used in combination, and a pressing block is used in the middle. The briquetting blocks are cut from steel pipe for the nylon straps that wrap around the bus handrails. Bending plates and pressing blocks cooperate with bolts and nuts to fix the bus handrail within the range of manual activities, and ...

Abstract

The invention discloses a handrail used for a large-inclination angle hydraulic support. Fixing parts are arranged on stand columns of the large-inclination angle hydraulic support, and bus handrailsare connected to the fixing parts. The fixing parts are clamping hoops which are formed by pressing steel plates, and the clamping hoops are fixed to the stand columns through bolts and nuts. Each clamping hoop comprises two bent plates, wherein pressing blocks are arranged at the butt-joint positions of the two bent plates and fixedly connected with the bent plates through bolts and nuts, and nylon belts are fixed to the pressing blocks and connected with the bus handrails. The handrail is good in standardization degree, convenient to purchase and low in cost because mold manufacturing is adopted; the handrail is smooth in appearance, bright in color, attractive, convenient to identify by operation workers and comfortable to use; the handrail is simple in structure and convenient to install and detach, and fixing positions can be adjusted.

Description

technical field [0001] The invention relates to a handrail of a hydraulic support for coal mines, in particular to a handrail for a hydraulic support with a large inclination angle. Background technique [0002] Coal is distributed in bands in the formation. Due to the movement of the earth's crust, most of the coal seams have a certain angle. Coal seams less than 10° are called near-horizontal coal seams, and coal seams greater than 20° are called high-dip coal seams. High-dip coal seams are mostly distributed in Ningxia and Yunnan-Guizhou regions of my country. To adapt to coal mining in large-inclination working faces, this requires fully mechanized mining hydraulic support equipment to be equipped with special facilities. [0003] Fully mechanized mining face operators need stable footrest and hand-holding facilities when walking on a large-inclination working face. Therefore, the pedestrian pedal behind the hydraulic support column on the working face with a large i...
