Description
Technical field
The utility model relates to the lifting position-limit control setup of the weight-lifting equipments such as driving, gauntry crane, relates in particular to mono beam overhead crane in bridge type lifting position-limit control setup.
Background technology
During work, be enclosed within the rope guide side-to-side movement with hook lifting on reel, when suspension hook rises to spacing height, rope guide drives and is arranged on limiting stopper and the position-limited lever in cylinder shell, position-limited lever touches cutoff limit switch, and directly disjunction lifting motor power circuit, stops operating motor.Proof is used in practice, and this limit device structure complexity, poor, the spacing inaccuracy of sensitivity and return stroke are long, easily damages rope guide, thereby cause inhibiting device misoperation or damage when wire rope inclined-pulling or strand steel rope; The mode of connection of circuit fire stop is complicated, easily causes power circuit short trouble during wiring error, and fault rate is higher.On the other hand, the circuit part of this class weight-lifting equipment is to adopt on reel housing, with one end of driving, a control box is respectively installed, by the control box on reel, control lifting and carriage walking, the control box of driving one end is controlled power circuit and large vehicle walking, utilize three pairs of conversing contactors to control respectively upper and lower, the left and right of suspension hook and the front and back action of driving, in the control box on reel housing, draw lower control cables and connect control button handle.Although this mounting means can be saved some manufacturing costs, exist that emergency stop switch is unreliable, driving when the Neutral Position generation electrical accident away from maintenance platform maintainer cannot be near maintenance, there is electrical accident while having weight on suspension hook and cannot transfer many disadvantages such as weight.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of mono beam overhead crane in bridge type lifting position-limit control setup is provided, and improves stability, the reduction equipment failure rate of weight-lifting equipment, is convenient to application and the operation of actual production.
Mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, includes limit switch, hangs and rise reel, bracing wire, heavily ring, wirerope, supporting plate, movable pulley and suspension hook.Hang and rise the main component that reel is mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, hang and rise being provided with and sliding assembly pulley of reel above, hang the one end that rises reel and be connected with drive motor, hanging a side that rises reel, be provided with limit switch, the fixed end of wirerope is connected to and hangs housing one side that rises reel, and the other end of wirerope is wound on to hang and rises on reel; In the fixed end of wirerope position slightly on the lower, be provided with heavily ring, heavily encircle by bracing wire and be connected to limit switch; Movable pulley is arranged on wirerope, movable pulley be provided with below suspension hook, being set in above of movable pulley is connected with supporting plate on wirerope.
Mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, integral structure is simple, installation and easy for operation, good stability, reliability is high.Use mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, can improve stability, the reduction equipment failure rate of weight-lifting equipment, be convenient to application and the operation of actual production.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model.1-limit switch 2-hang rises reel 3-bracing wire 4-heavily encircle 5-wirerope, 6-supporting plate, 7-movable pulley, 8-suspension hook.
The specific embodiment
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, include limit switch 1, hang rise reel 2, bracing wire 3, heavily encircle 4, wirerope 5, supporting plate 6, movable pulley 7 and suspension hook 8.Hang and rise the main component that reel 2 is mono beam overhead crane in bridge type lifting position-limit control setups described in the utility model, hang and rise being provided with and sliding assembly pulley of reel 2 above, hang the one end that rises reel 2 and be connected with drive motor, hanging a side that rises reel 2, be provided with limit switch 1, the fixed end of wirerope 5 is connected to and hangs housing one side that rises reel 2, and the other end of wirerope 5 is wound on to hang and rises on reel 2; In the fixed end of wirerope 5 position slightly on the lower, be provided with and heavily encircle 4, heavily encircle 4 and be connected to limit switch 1 by bracing wire 3; Movable pulley 7 is arranged on wirerope 5, movable pulley 7 be provided with below suspension hook 8, being set in above of movable pulley 7 is connected with supporting plate 6 on wirerope 5.Be attached with a limit switch hanging the snapped-in position that rises steel rope wedging termination on reel housing, the rocking lever termination of limit switch will, near steel wire wedging termination, be used for controlling the control power supply of contactless for hoisting; To weigh ring set on wirerope, making heavily to encircle can be along wirerope moving up and down freely, and heavily the weight of ring is advisable with stretchy limit switch; With the thin galvanized steel wire rope of diameter 3mm, hang heavily ring and be fixed on the rocking lever termination of limit switch, tension limit switch, does a strong point at the lower end position of rocking lever travel displacement, prevents because of the excessively mobile limit switch that damages of rocking lever; At a racket-shaped supporting plate of suspension hook top weldering, the circular hole in the middle of supporting plate should be much larger than wirerope diameter, and steel rope can not wear and tear while moving up and down.Principle of work: when suspension hook rises to heavy ring position, the moving heavily ring of supporting plate holder rises, and seizing wire loses pulling force, makes limit switch homing action, and the short contactless for hoisting control circuit of opening cuts off motor rising power supply, thereby reaches spacing object.By regulating the length of seizing wire to change spacing height.Suspension hook declines, and supporting plate leaves heavily ring, and limit switch moves connection control circuit, and return stroke only has 10cm left and right.The design of circuit part: contactless switch and the control transformer of controlling driving six direction are all concentrated in a control box, and increase a contactless switch of controlling power circuit, SB0 controls by emergency stop switch, control box is arranged on to one end of driving; Lengthen power lead and the control cables line of lifting motor, left and right movable motor simultaneously, receive in control box; In winding drum shell body position, install again a connecting terminal block additional, control cables line is received on control button handle by terminal row again, utilize button handle to control.Mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, integral structure is simple, installation and easy for operation, good stability, reliability is high.Use mono beam overhead crane in bridge type lifting position-limit control setup described in the utility model, can improve stability, the reduction equipment failure rate of weight-lifting equipment, be convenient to application and the operation of actual production.
