Abstract
The utility model discloses a safety protection device of a coal mining support, which comprises a separation board hinged to the top portion of the support. The separation board is suspended on the support; a hydraulic oil cylinder is fixedly installed on the support on the outer side of the separation board; and the top end of a piston rod of the hydraulic oil cylinder is hinged onto the lateral wall of the separation board. When in use, the separation board is placed down through the hydraulic oil cylinder, and an operator is protected in a relatively closed safety space and monitors the work of a coal mining machine through a transparent observation window, thereby the safety protection device effectively reduces damage of coal dust, blasting and rock falling to the operator.
Description
Technical field
The utility model relates to the coal mining field of stents, specifically is a kind of safety guard of the support of mining.
Background technology
The hydraulic support that use in the recovery of subterranean colliery is the important component part of fully-mechanized mining equipment.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.It and the supporting use of coal-winning machine realize the coal mining comprehensive mechanization, solve the contradiction that roof control in the mechanical coal mining work lags behind coal work, further improve and mine and the usefulness of haulage device.But present coal mining support does not generally have safety guard, serious threat workman's life security.
The utility model content
The purpose of this utility model provides a kind of safety guard of the support of mining, and the operator is positioned at the division board rear side, ensures the life security of coal miner to greatest extent, and is easy to operate.
The technical solution of the utility model is as follows:
A kind of safety guard of the support of mining includes the division board that is articulated in a top of the trellis, and division board hangs on the described support, is installed with hydraulic jack on the support in the division board outside, and the top of hydraulic cylinder piston rod is articulated on the sidewall of division board.
Described division board top is provided with observation port.
Division board of the present utility model and coal mining support are wide; during use division board is put down by hydraulic jack; operating personnel are protected in the safe space of a relative closure; by transparent windows monitoring coal mining machine work, thereby effectively reduce coal dust, the injury of cash of blowing out, fall to operating personnel.Especially in the high inclination-angle support, when objects such as the float coal that coal mining activity produces, broken cash, rock drop into lower, can cause very big threat when a high position is carried out to the operating personnel that are in low level.Adopt in the support at big gun, not only can protect operating personnel, can also protect column and hydraulic control system to avoid blowing out the infringement of the splash that produces.
Of the present utility model in light weight, the support front end dip can not appear.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a partition plate structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing; a kind of safety guard of the support of mining; include the division board 2 that is articulated in support 1 top; division board 2 hangs on the support 1; be installed with hydraulic jack 3 on the support 1 in division board 2 outsides; the top of hydraulic jack 3 piston rods is articulated on the sidewall of division board 2, and division board 2 tops are provided with observation port 4.
Claims (2)
1. the safety guard of the support of mining; it is characterized in that: include the division board that is articulated in a top of the trellis; division board hangs on the described support, is installed with hydraulic jack on the support in the division board outside, and the top of hydraulic cylinder piston rod is articulated on the sidewall of division board.
2. the safety guard of coal mining support according to claim 1 is characterized in that: described division board top is provided with observation port.
