Description

Cage

The utility model belongs to the mine safety device, is mainly used in the mancage that mine vertical shaft promotes.

Existing sliding curtain type jar curtain, manually the holder of jar curtain is caught on after opening the position when opening curtain, go to collude when closing curtain by curtain deadweight whereabouts and close, shortcoming is that this jar of curtain dimensions do not meet " safety regulations in coal mine " the 347th, if make by " safety regulations in coal mine ", then weigh more than 10 kilograms, one people opens the curtain difficulty, and curtain is opened in jar interior occupant's inconvenience simultaneously, needs open curtain cage peripheral hardware special messenger, cause the pit shaft trickle to pour into out in curtain people's the coat-sleeve, and it is slower to open curtain speed.

The purpose of this utility model is to propose a kind of jar curtain that " safety regulations in coal mine " made that both met, and can laborsaving, conveniently open curtain again, improves and opens curtain speed, saves sole duty and opens the curtain personnel.

In order to achieve the above object, the solution that the utility model adopts is that greatly heavily stone roller, little heavy stone roller are set on sliding curtain type jar curtain, restraints to be connected to rope to reach the counterweight effect on the different curtain rods, when opening curtain when opening, little heavy stone roller is fallen lowest order by the permanent magnet adhesive, reaches automatic positioning action.

The utility model has the advantages that: adopted balance weight mechanism, alleviated and opened curtain weight; Adopt permanent magnet, conveniently opened curtain, improved the curtain speed of opening; In jar or jar outer occupant only use the strength of 1/2～1/3 whole curtain rod weight, all can conveniently open curtain, save sole duty and open the curtain personnel; Facts have proved and improve conevying efficiency more than 15%, the mechanism of employing is simple and reliable, durablely easily repaiies, and is safe and reliable, alleviates the curtain that falls and impacts, even the utility model breaks down, also do not influence cage and transports the occupant by existing sliding curtain type jar curtain action.

The utility model is described in further detail below in conjunction with drawings and Examples:

Accompanying drawing 1 is that the utility model jar curtain closes the curtain schematic diagram.

Accompanying drawing 2 is opened the curtain schematic diagram for the utility model jar curtain.

As Fig. 1, adorn 2 guide rods (2) on the cage (1), curtain rod (4) two side welds have curtain ring (3) to be enclosed within the guide rod (2), equidistantly fuse with two chain links (8) between all curtain rods (4), hang on the cage (1), two seizing wires (5), (7) one connect on the following and middle curtain rod (4) respectively, the other end is respectively by sister block mechanism (6), (9) and little heavy stone roller (11), greatly heavily stone roller (10) links to each other, greatly heavily there is through hole (15) in the axle center of stone roller (10), make things convenient for seizing wire (5) by also being connected with little heavy stone roller (11), little heavy stone roller (11), greatly heavily stone roller (10) is contained in the non iron conduit (12), conduit (12) be connected in inside and outside the cage (1) all can, permanent magnet (13) and cushion pad (14) are equipped with in conduit (12) bottom.

When opening curtain, in only needing jar or a jar outer people hold up on the centre position of next root curtain rod (4) and move, at this moment move on all curtain rods (4), greatly heavily stone roller (10), little heavy stone roller (11) moves down simultaneously, when all curtain rods (4) arrive when opening, little heavy stone roller (11) is by permanent magnet (13) adhesive, all curtain rods (4) can not fall certainly when loosing one's grip, and as Fig. 2, this moment, the occupant can go out into.As long as the going up most and press 50～100 millimeters of curtain rod (4), little heavy stone roller (11) separates with permanent magnet (13) when closing curtain, and curtain rod (4) is fallen by deadweight and closed the position, as Fig. 1.For safety action reliable, must make little heavy stone roller (11) equal a curtain rod (4) weight, greatly heavily stone roller (10) equals two curtain rods (4) weight, the surperficial suction of permanent magnet (13) is greater than the gross weight of two curtain rods (4) and two chain links (8), and cushion pad (14) can slow down little heavy stone roller (11) to be impacted with the attraction of permanent magnet (13).

Claims
