Abstract

The invention discloses an umbrella-shaped support type temporary support device, comprising a tail articulated hydro cylinder, a hydraulic control valve arranged on the hydro cylinder, a hanging ring, a boom and a hydraulic station fixedly connected at the lower part of the hanging ring, the boom is a screw rod and is fixedly arranged on a disk-type base at the lower part of the boom by two screw nuts which are respectively arranged at the upper part and lower part of the base, a link plate penetrates the boom, a height-adjusting screw nut is arranged on the boom, a plurality of hinged supports are arranged at the periphery of the base, each hinged support is hinged with the hydro cylinder by a hinge shaft, a terminal disc is fixed on the top of a plunger piston of the hydro cylinder, a hydro cylinder fixture is arranged on the upper part of a cylinder barrel of the hydro cylinder, a movable hanger is hinged on the hydro cylinder fixture, control chains with the same number as the hydro cylinders are hinged around the link plate, the other end of the control chain is connected with the movable hanger by a hook, the hydraulic control valves are communicated with hydraulic distributing valves on hydraulic pressure stations by own oil pipes. The temporary support device of the invention does not affect construction operation and enjoys large support area and high security.

Description

technical field [0001] The invention relates to a temporary support device, in particular to an umbrella-shaped support type temporary support device used in shaft construction in coal mines, metallurgical and non-metallic mines, etc. to ensure the safety of construction personnel. Background technique [0002] In the process of mine shaft construction, construction safety is becoming more and more important. Faced with changes in geological conditions during the construction of level roads, the firmness and stability of the roof of the roadway determines the safety of the construction personnel below it. Only by ensuring the safety of the construction personnel can it bring benefits to the enterprise. Huge economic benefits. [0003] The safety work of underground roadway construction is a complex systematic project. At present, the safety management depends on management and input. The most important thing in the investment is various safety facilities. In the past, capp...
