Abstract

The utility model discloses a movable pulley hook head for vertical shaft sinking and hoisting, comprising a hook head, wherein a movable pulley is installed on the top of the hook head. According to the utility model, via the use of the movable pulley hook head, a vertical shaft sinking and hoisting system realizes movable pulley traction, so that the maximum static tension acting on the steel wire rope of a hoist drum is halved, and then the diameters of the steel wire rope and the hoist drum can be reduced on the premise of guaranteeing safety; and the specifications and the models of the selected hoist are reduced, so that equipment investment can be remarkably reduced, and efficiency during sinking and hoisting, and hoisting capacity can be improved. In particular, for a mine in which the vertical shaft sinking and hoisting system needs to be transformed, the movable pulley cage has the advantages of being less in investment, few in added facilities, easy to perform technical transformation, convenient to install and use, short in construction period, and basically having no influence on the production.

Description

The vertical shaft sinking shaft promotes uses the movable pulley eave tile

Technical field

The utility model relates to vertical shaft for mine sinking shaft lifting and uses device, is specifically related to eave tile wherein.

Background technology

During existing vertical shaft for mine sinking shaft construction, personnel are connected lifting with material be to finish by worker's type eave tile that the steel wire rope of hoist end connects well-bucket of slinging.Be the single wire winding type elevator system; The hang of steel rope is that an end is wrapped on the lifting drum, and the other end is by directly connecting worker's type eave tile well-bucket of slinging after the head sheave guiding, and at this moment, steel rope is stressed be lifting load weight and the steel rope sum of conducting oneself with dignity.According to the movable pulley principle, use movable pulley pulling object, the rope two ends are stressed to be impartial, and is the object gravity that draws half, that is: need only to apply at traction end to be pulled half power of object gravity and just can to mention object.According to this principle, under the condition that does not change existing gig, the eave tile device is done appropriate reconstruction, achieve with the movable pulley mode and draw well-bucket, just can significantly improve the hoisting capacity of gig and the safety of lifting.

The utility model content

Gig was realized with movable pulley mode hoppet when the purpose of this utility model was to make sinking shaft, poor poor with the maximum dynamic tension to reduce the biggest quiet tension that steel rope was born, the gig ability is not fully exerted, safe operation, and reduce construction and equipment investment expense.

For achieving the above object, the technical scheme taked of the utility model is; A kind of vertical shaft sinking shaft promotes and uses the movable pulley eave tile, comprises eave tile, and the top of this eave tile is equipped with movable pulley.

The utility model is by using the movable pulley eave tile, vertical shaft sinking shaft elevator system has realized the movable pulley traction, make and act on that the biggest quiet tension of steel rope reduces by half on the lifting drum, can under safing prerequisite, reduce steel rope and lifting drum diameter, and the specifications and models of selecting gig have been reduced, can significantly reduce equipment investment, efficient and hoisting capacity when improving the sinking shaft lifting.The mine that particularly need to transform vertical shaft sinking shaft elevator system, have small investment,, the facility of increase is few, technological transformation is easy, and is easy to install, short construction period does not affect the advantage of construction substantially.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the lateral plan of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, a kind of vertical shaft sinking shaft promotes and uses the movable pulley eave tile, comprises eave tile, and the afterbody of described eave tile 7 is equipped with movable pulley 1.Mounting means is: utilize the mounting hole flush fit of described eave tile 7 afterbodys that bearing pin 6 is installed, and these bearing pin 6 two ends captive joint supports 3, movable pulley axle 2 is installed in the upper end of this support 3, by bearing 4 described movable pulley 1 is installed on this movable pulley axle 2.Liner 5 is installed, to reduce the wearing and tearing of hoisting cable in the grooving of this movable pulley.

Using method of the present utility model: hoisting cable one end is fixed on sheave wheel platform or the derrick, the other end is wrapped on the lifting drum after walking around movable pulley on the eave tile, gig is by walking around the rope traction well-bucket lifting of movable pulley, can make the biggest quiet tension that acts on the steel rope reduce by half this moment, thereby the gig hoisting capacity is significantly improved.

Claims

1. a vertical shaft sinking shaft promotes and uses the movable pulley eave tile, comprises eave tile, and it is characterized in that: the afterbody of described eave tile (7) is equipped with movable pulley (1).
