Abstract

A mine inclined shaft lifting pendent type automatic retarder can prevent a mine car from losing control and plunging down a platform to cause accidents when a steel wire rope is broken during a lifting process of an inclined shaft. The retarder comprises a retarding plowshare, mine cars, a lifting steel wire rope and a retarding attaching rope; the tail portion of the retarding plowshare is connected with rear portions of the mine cars which are connected through chain rings, the lower end of the lifting steel wire rope is connected with the mine cars, and the upper end of the retarding attaching rope and the lower end of the retarding attaching rope are respectively connected with the head of the retarding plowshare and the lifting steel wire rope. When the retarder works, the retarding attaching rope enables the retarding plowshare to be suspended and leave the ground; and when the lifting steel wire rope, the retarding attaching rope or the chain rings are broken, the retarding attaching rope is loose, and the head of the retarding plowshare loses pulling force and is inserted to the ground downwards. A declining mine car is skidded, and safety accidents caused by the car plunging down the platform are avoided. The retarder is simple in structure, sensitive and accurate, low in cost, and easy to operate.

Description

The hanging automatic anti-slipped device of mine inclined shaft hoisting

Technical field

The utility model relates to a kind of mine inclined shaft hoisting catcher, especially can avoid hoisting cable to break or chain link is broken and caused that mine car is out of control to sweep away the hanging automatic anti-slipped device of a kind of mine inclined shaft hoisting that the inclined shaft lower platform causes safety misadventure.

Background technology

At present, the catcher that known mine inclined shaft hoisting uses is a lot, the kind such as electronic, gentle formula is arranged, hit, these catchers play a role safely to mine inclined shaft hoisting, its weak point be sensitive not, action is not accurate enough, complex structure, usage condition is harsh, the cost height is not easy to operate etc., brings in actual applications inconvenience.

Summary of the invention

In order to overcome anti-sport car some deficiency in structure and practical application of existing mine inclined shaft hoisting, the utility model provides a kind of mine inclined shaft hoisting hanging automatic anti-slipped device, this utility model is not only simple in structure, be active in one's movements, cost hangs down easy care, and easy operating, avoid at any time the mine car inclined shaft lower platform that sweeps away out of control to cause safety misadventure.

The technical scheme that its technical matters that solves the utility model adopts is: the hanging catcher of mine inclined shaft hoisting is comprised of anti-colter, mine car, hoisting cable and the attached rope of anti-race of running, anti-race colter is positioned at the rear portion of mine car, the anti-race between colter afterbody and the mine car links to each other both by latch, the anti-colter that runs can rotate up and down around latch, there is chain link to connect between the mine car, the hoisting cable lower end links to each other with mine car, the anti-attached rope lower end of running links to each other with the anti-colter head that runs, and the upper end strides across mine car top and is connected with hoisting cable.During normal hoisting, the attached rope of anti-race will be prevented running colter and hang overhead, the attached rope tension of anti-race, when hoisting cable or chain link are broken, anti-to run attached rope loose or broken, and the anti-colter that runs loses the anti-attached rope tension that runs, and is subjected to the self gravitation effect down to inject the floor, tunnel, in time check the downslide of mine car, avoid mine car to sweep away lower platform and cause safety misadventure.

The beneficial effects of the utility model are, and are simple in structure, safe and reliable, are suitable for all inclined shaft tunnel mine cars and promote and use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is exterior structure figure of the present utility model.

Fig. 2-the 2nd, the work schematic diagram when disconnected rope occurs the utility model hoisting cable.

Fig. 2-the 3rd, the work schematic diagram when the anti-attached rope of race of the utility model and chain link are broken.

Among the figure 1, the anti-colter that runs, 2, anti-ly run attached rope, 3, latch, 4, mine car, 5, chain link, 6, hoisting cable, 7, rail, 8, the floor, tunnel.

The specific embodiment

In Fig. 1, anti-race colter (1) is positioned at the rear portion of mine car (4), the anti-race between colter (1) afterbody and the mine car (4) links to each other both by latch (3), there is chain link (5) to connect between the mine car (4), hoisting cable (6) lower end links to each other with mine car (4), anti-attached rope (2) lower end of running links to each other with anti-colter (1) head that runs, and the upper end strides across mine car (4) top and is connected with the lifting steel cable.

In the embodiment shown in Fig. 2-1, the anti-colter (1) that runs is prevented running attached rope (2) extension from earth polar, tunnel (7), and mine car (4) promotes working properly.

In Fig. 2-2, when hoisting cable (6) when breaking, anti-attached rope (2) top of running loses pulling force, and anti-colter (1) head that runs loses anti-attached rope (2) pulling force that runs, be subjected to the self gravitation effect to insert floor, tunnel (8) downwards, check the undershoot of mine car (4).

In Fig. 2-3, anti-race attached rope (2) or chain link (5) are when breaking, and the anti-colter (1) that runs loses the anti-pulling force that runs attached rope (2), is subjected to self gravitation effect insertion earth polar, tunnel (8), checks the undershoot of mine car (4).

Claims

1. hanging automatic anti-slipped device of mine inclined shaft hoisting, it is by the anti-colter (1) that runs, mine car (4), hoisting cable (6) and the anti-attached rope (2) that runs form, it is characterized in that: anti-race colter (1) is positioned at the rear portion of mine car (4), by latch (3) both are connected between its afterbody and the mine car (4), hoisting cable (6) lower end links to each other with mine car (4), anti-attached rope (2) lower end of running links to each other with anti-colter (1) head that runs, and the upper end strides across mine car (4) top and is connected with hoisting cable (6).
