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
The present invention relates to a kind of temporary support device, especially a kind of sinking and driftings such as colliery, metallurgy, non-metal mine that are used for are for guaranteeing the umbrella stull formula temporary support device of constructor's safety.
Background technology
In mine sinking and drifting process, construction safety seems and becomes more and more important, in the face of the variation of geological conditions, the firm stable of back has determined constructor's safety in its lower section during lane construction, guarantees that constructor's safety could be brought huge economic benefit to enterprise.
The work of underworkings construction safety is a complicated system engineering, grabs safety one tube reason at present, and two by dropping into.Important in the input is exactly various safety device.Sinking and drifting taked to attach the names of pre-determined candidates a post, hydraulic pressure forestope as temporary lining more in the past, was subjected to the restriction in work plane space during use, mainly showed: 1, take the area of roadway floor, cause mobile roof-bolter, air drill and connection geomantic omen pipeline difficulty thereof.2, the effective area of supporting roof is little, and safety is little.For this reason, design a kind of area that does not take roadway floor, do not influence mobile roof-bolter, air drill and the pipeline operation of connection geomantic omen thereof, the supporting roof effective area is big, and safe umbrella stull formula temporary support device is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of area that does not take roadway floor, does not influence mobile roof-bolter, air drill and the pipeline operation of connection geomantic omen thereof, and the supporting roof effective area is big, safe umbrella stull formula temporary support device.
The technical scheme that the present invention solves its technical problem is:
A kind of umbrella stull formula temporary support device, by afterbody radial type oil cylinder, be installed in the hydraulic control valve on the oil cylinder, suspension ring, the suspension rod and the Hydraulic Station that are fastened on the suspension ring bottom are formed, described suspension rod is a rhizoid bar, suspension rod is installed on the dish-type base of its underpart by nut, the nut of fixed derrick is to be arranged on two of base upper and lower, on suspension rod, be coated with carrier bar, suspension rod is provided with heightens nut, periphery at base is provided with a plurality of free bearings, on each free bearing, all be hinged with oil cylinder by hinge, plunger head at oil cylinder is fixed with, top at the cylinder barrel of oil cylinder is installed with the oil cylinder card, be hinged with Removable hook on the oil cylinder card, around carrier bar, be hinged with and the as many Quality Initiative of oil cylinder quantity, the other end of Quality Initiative and Removable hook clasp joint, described each hydraulic control valve all oil pipe by separately are communicated with hydraulic distributing valve on the Hydraulic Station.
The technical scheme that the present invention solves its technical problem can also be:
The quantity that is hinged on the oil cylinder of perimeter of the present invention is 3 or 4.
The invention has the beneficial effects as follows:
Utilize anchor pole in the tunnel design supporting itself as stress point, is connected with leading screw by shackle, flexible the making of four oil cylinders on the leading screw takes over a business to hold back, and the support scope of taking over a business can be passed through the length adjusting of leading screw.1, simple in structure, stable performance, easy to maintenance, economy and durability; 2, volume is little, applicability is strong; 3, not taking the roadway floor area, is work plane construction equipment conveniently moving; 3, improve working conditions, guarantee safe construction.
Description of drawings
