Abstract
The utility model relates to a trolley traction driving device and belongs to the technical field of trolley driving in hoisting machinery. The trolley traction driving device aims at solving the technical problems of reducing the height of a trolley, and simplifying a driving device of the trolley so as to enable the trolley to be suitable for underground work. According to the adopted technical scheme, the trolley traction driving device comprises an electric hoist and a crown block, wherein a rack is a rectangular frame formed by two main beams and two end beams, the trolley is installed on the two main beams in the rack, the electric hoist is fixedly installed on one end beam of the rack, the crown block is installed on the other end beam of the rack, one end of a steel wire rope in the electric hoist is fixed on the trolley, and the other end of the steel wire rope passes by a winding drum in the electric hoist and then passes by the crown block to be also fixed on the trolley. The trolley traction driving device is applicable to underground traveling.
Description
Technical field
A kind of dolly traction drive of the utility model belongs to dolly actuation techniques field in the elevator machinery.
Background technology
In the process that fully-mechanized mining working is arranged, need install hydraulic support.According to the conventional method, be that these volumes are big, the hydraulic support that quality weighs is after the whole assembling in ground is complete, winch on the flat truck, integral body is gone into the well, after going into the well, be transported to driving surface with winch again, must lean on manpower with winch, jack, crowbar the hydraulic support holder to be drawn then and reverse 90 ° and be in place.This method complicated operation, labor strength is big, put irregular, set-up time is long, and if want to realize mechanization, will use down-hole driving, at this moment, dolly in the driving of common ground is because highly more high shortcoming is just inapplicable, and the movement of common dolly directly drives wheel by actuating device, lowers under the situation of dolly height inapplicable at needs as far as possible.
The utility model content
A kind of dolly traction drive of the utility model overcomes the deficiency that prior art exists, technical matters to be solved is: reduce the dolly height, simplify drive car, make dolly be suitable for underground work, and then realize that hydraulic support is carried out mechanization to be installed, reduce working strength of workers, improve the speed that hydraulic support is installed.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of dolly traction drive, comprise electric block and fixed pulley, frame is the rectangular frame of mainly being made up of two girders and two butt beams, dolly is installed on two girders in the frame, electric block is fixedly mounted on the butt beam of frame, fixed pulley is installed on another butt beam of frame, an end of steel rope is fixed on the dolly in the described electric block, and the other end of steel rope is walked around reel in the electric block, also is fixed on the dolly after walking around fixed pulley again.
The beneficial effect that the utility model compared with prior art has is: the utility model has reduced the height of dolly by the parallel motion of electric block and steel rope control dolly, and is simple in structure, practical and convenient.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 is that electric block, 2 is that fixed pulley, 3 is that dolly, 4 is that frame, 5 is steel rope.
The specific embodiment
As shown in Figure 1, a kind of dolly traction drive of the utility model, comprise electric block 1 and fixed pulley 2, frame 4 is the rectangular frame of mainly being made up of two girders and two butt beams, dolly 3 is installed on two girders in the frame 4, electric block 1 is fixedly mounted on the butt beam of frame 4, fixed pulley 2 is installed on another butt beam of frame 4, an end of steel rope 5 is fixed on the dolly 3 in the described electric block 1, and the other end of steel rope 5 is walked around reel in the electric block 1, also is fixed on the dolly 3 after walking around fixed pulley 2 again.
The utility model is by pulling the parallel motion that steel rope 5 is realized dolly 3 by electric block 1 forward or reverse, and is simple and convenient.
