Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] A remote-controlled mechanical retractable prop is composed of a top plate 1, an upper cylinder 2, a fine-tuning collar 3, a latch 4, a lower cylinder 5, a pull lever 6, a fastening device 7, and a base 8. A layer of rubber is added to the top plate 1 to increase the frictional resistance between the top plate and the rock to prevent relative sliding between the top plate and the top plate; The top plate 1 can be rotated within a range of 360° to adapt to top plates of different heights; a fine-tuning collar 3 is installed between the upper column 2 and the lower column 5, and four sets of fine-tuning steps are arranged on the fine-tuning collar 3 , the height difference between each two groups of steps is h, and the bolt 4 is connected to the fine-tuning collar with an iron chain; the lower end of the lower column 5 is inserted into the fastening device 7 and fixed ...

Abstract

The invention relates to a remotely controlled mechanical telescopic support pillar, and belongs to the field of construction supporting. The support pillar consists of a top disc, an upper pillar body, a fine adjustment ferrule, a bolt, a lower pillar body, a pull rod, a fastening device and a base, wherein the upper pillar body and the lower pillar body are tubular; fine adjustment holes are formed on the upper pillar body and the lower pillar body at intervals of H; the fine adjustment ferrule is arranged between the upper pillar body and the lower pillar body and is provided with four groups of fine adjustment steps; the height difference of every two groups of steps is h; and the fastening device is realized according to a cam principle and achieves a labor-saving effect by matching with a lever principle. The support pillar has the advantages of light weight, wide adjustable height range, high supporting strength and safety, and capability of being disassembled in a remote control mode, is convenient to transport and erect and reliable in supporting, and has a wide application range.

Description

technical field [0001] The invention relates to the field of engineering support, in particular to a remote-controlled mechanical telescopic support. Background technique [0002] Roof accidents are one of the major hazards in the fields of mining engineering, geotechnical engineering, and tunnel engineering. How to effectively ensure the safety of the roof when workers are working has always been a core issue in engineering management research. At present, the temporary support forms commonly used in mining and engineering construction mainly include: hydraulic props, hydraulic props, bolt supports, wood supports, steel supports, etc. Although they have significant support effects, they are not completely effective. Safeguard the personal safety of workers. The existing support forms have different defects to a certain extent, and the specific comparison is shown in the table below. [0003] Support type There is a problem steel support Large consu...
