The species of crane gear is a lot, and wherein more typically arrive is planer-type crane and hoist engine, and hoist engine is to be driven reel, winding cords to complete to draw the device of work by manpower or machine power, can be with vertical-lift, horizontally or diagonally traction weight.The structure of hoist engine is: include pedestal the 1st, reductor the 2nd, reel the 11st, motor the 12nd, braked wheel 14 and Breake Electromagnet 16, reductor is installed in the side of pedestal, the input of reductor connects motor output shaft 13 by braked wheel, and the output of reductor connects reel by rotary shaft 17.During use, motor via reducer band movable reel action, steel wire on reel is released or is regained, complete reduction and the rising of weight, when needs weight is parked in certain height, Breake Electromagnet action, friction clamp 15 is driven to clamp braked wheel by linkage, make reel stop operating, but find in actual use, after this structure uses for a long time, owing to motor speed is higher, between braked wheel and friction clamp, friction is acutely, and friction clamp needs to regularly replace guarantee work safety, also has an impact the work safety of motor.
Content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, the durable hoisting device of one that simple in construction, stable performance, reliability are high is provided.
The present invention adopts the technical scheme that:
A kind of durable hoisting device, including pedestal, reductor, braked wheel, motor and reel, reductor is installed in the side of pedestal, the input of this reductor connects motor by braked wheel, it is characterized in that: the output of this reductor connects the rotary shaft of reel by a clutch, this reel both ends are respectively mounted a brake disc, and a Pneumatic clamp is installed in contraposition on each brake disc, and this two Pneumatic clamps connect air pump by magnetic valve.
And, described clutch includes fixed disk, mobile dish and shifting axle, make for making the two fixture block linking and draw-in groove on the fixed disk end face relative with mobile dish, described mobile dish is co-axially mounted one end of shifting axle away from the end face of reductor, this shifting axle other end is spacing to be inlaid in described rotary shaft, and the end that this shifting axle stretches out rotary shaft connects the piston rod of rotary cylinder that this side end of rotary shaft is filled.
And, described fixture block and draw-in groove are four.
And, described shifting axle makes multiple fin homoaxial with shifting axle near the outer rim radial equipartition of mobile dish, making multiple chute on the inner edge of the rotary shaft of the plurality of fin phase contraposition, described fin can slide axially along rotary shaft at chute and make mobile dish be combined with fixed disk or depart from.
And, described rotary cylinder connects described air pump by described magnetic valve.
Advantages of the present invention and good effect be:
nullIn the present invention,Reductor connects reel by clutch,When weight stops,First braked wheel braking,Reductor moment is made to slow down,Now rotary cylinder work,Shifting axle is retracted by piston rod,Mobile dish and fixed disk is made to depart from,External impetus is made to disappear,Two Pneumatic clamp actions simultaneously,The brake disc of both sides is held tightly,After mobile dish and fixed disk depart from,Braked wheel stops braking,Reductor recovers to rotate,When weight continues motion,Rotary cylinder action,Shifting axle is pushed back by piston rod,Mobile dish and fixed disk is made to recombine,External impetus is made to recover,During Zheng Ge,Braked wheel has only to brake a little meeting youngster,Reduce frictional dissipation,Motor also will not be chronically under passive on-position,Reel is due to the effect of Pneumatic clamp simultaneously,Brake speed is fast,The high precision of weight,Overall work is safer、In hgher efficiency.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, it is impossible to limits protection scope of the present invention with following embodiment.
A kind of durable hoisting device, as shown in figures 1-4, including pedestal the 1st, reductor the 2nd, braked wheel the 14th, motor 12 and reel 11, reductor is installed in the side of pedestal, the input of this reductor connects motor by braked wheel, the innovation of the present invention is: the output of this reductor connects the rotary shaft 17 of the reel being rotatably installed in axle sleeve 8 by a clutch 3, this reel both ends are respectively mounted a brake disc 6, a Pneumatic clamp 4 is installed in contraposition on each brake disc, and this two Pneumatic clamps connect air pump 9 by magnetic valve 7.
In the present embodiment, described clutch includes that the 23rd, fixed disk moves dish 21 and shifting axle 18, make for making the two fixture block 22 linking and draw-in groove 24 on the fixed disk end face relative with mobile dish, fixture block and draw-in groove are four, described mobile dish is co-axially mounted one end of shifting axle away from the end face of reductor, this shifting axle other end is spacing to be inlaid in described rotary shaft, and the end that this shifting axle stretches out rotary shaft connects the piston rod of rotary cylinder 10 that this side end of rotary shaft is filled.
Described shifting axle makes multiple fin 20 homoaxial with shifting axle near the outer rim radial equipartition of mobile dish, multiple chute 19 is made on the inner edge of the rotary shaft of the plurality of fin phase contraposition, shifting axle axially moving reciprocatingly along rotary shaft under the effect of rotary cylinder, make fin slide in chute, make mobile dish be combined with fixture block and the draw-in groove of fixed disk or depart from simultaneously.Described rotary cylinder connects described air pump by described magnetic valve.
The course of work of the present invention is:
1. reductor connects reel by clutch, when weight stops, and first braked wheel braking, reductor moment is made to slow down, now rotary cylinder work, shifting axle is retracted by piston rod, makes mobile dish and fixed disk depart from, external impetus is made to disappear, two Pneumatic clamp actions simultaneously, the brake disc of both sides is held tightly by friction plate 5, after mobile dish and fixed disk depart from, braked wheel stops braking, and reductor recovers to rotate.
2., when weight continues motion, rotary cylinder action, shifting axle is pushed back by piston rod, makes mobile dish and fixed disk recombine, makes external impetus recover, and weight continues motion.
In the present invention, braked wheel has only to brake a little meeting youngster, reduces frictional dissipation, motor also will not be chronically under passive on-position, and reel is due to the effect of Pneumatic clamp simultaneously, and brake speed is fast, the high precision of weight, overall work is safer, in hgher efficiency.
