Description

Lever automatic guidance lifting clamp
Technical field
The utility model relates to the hoisting hook transportation technique of steel billet, refers in particular to a kind of lever automatic guidance lifting clamp.
Background technology
Elevator machinery is indispensable a kind of instrument in commercial production and the transportation.In steel and iron industry, along with the stock production of steel billet, especially along with the developing rapidly of cast steel, the demand of steel billet is increasing.For enhancing productivity and safety, all kinds of hoisting cranes have also obtained developing rapidly with the production of steel billet clamp.In all kinds of elevator machineries, the lifting gripping mechanism is to use at present more a kind of elevator machinery, and the quality of caliper unit will influence the performance of whole clamp hoisting device in clamp hoisting device.So we have great significance to the optimal design of caliper unit.At present, the steel plate-billet clamp of making according to the generation of gripping power, can be divided into external force formula clamp and gravity type boat davit clamp two major types both at home and abroad.External force formula clamp, the gripping power of its clamping plate slab all is to be produced by external force with the power of finishing the clamp on-off action.As hydraulic pressure slab clamp and motor machine slab clamp.The gripping power of its clamping plate slab all is to be produced by power, and gripping power be certain value substantially, has nothing to do with the weight of plate slab.Gravity type boat davit clamp, the gripping power of its clamping plate slab are that the weight by plate slab itself produces by leverage, and its gripping power is not a definite value, but along with the slab deadweight changes and changes, steel plate weight is heavy more, and gripping power is big more, otherwise the plate slab deadweight is light more, and gripping power is more little.The domestic and international at present gravity type boat davit steel plate-billet clamp of making, the switching of its clamp is the same with external force formula clamp, need be carried out the on-off action of clamp by power.Open and close clamp as electric opening and closing clamp and hydraulic pressure.But it is much smaller with respect to the needed power of external force formula clamp.Because it only needs to overcome the resistances such as part deadweight of clamp.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of rational in infrastructure, easy to operate lever automatic guidance lifting clamp is provided.
The technical solution of the utility model is a kind of lifting clamp that comprises following structure of structure:
Comprise arm, beam axle, automatic control device, go up tong arm, following tong arm and adapter shaft, arm tie-beam axle wherein, beam axle two ends are symmetrical arranged tong arm, following tong arm, automatic control device, described upward tong arm, the following every end of tong arm are two one group, are hinged to flexible caliper unit by adapter shaft.
Advantage of the present utility model and beneficial effect:
The utility model adopts the mechanical lever principle, and principle is simple.Parts slide formula gravity recloser in this clamp is compared with the rotary switch device, and is simple in structure, switch is flexible, the trouble point is few; Energy-conservation, to compare with the motor switch formula, itself does not need external energy, and all actions are all finished by the lifting of load hook; No electronic component, each joint adopts grease lubrication, adapts to work in hot environment.

The specific embodiment
By Fig. 1 to 5 as can be known, the utility model comprises arm 1, beam axle 7, automatic control device 2, goes up tong arm 3, following tong arm 5 and adapter shaft, arm 1 tie-beam axle 7 wherein, beam axle 7 two ends are symmetrical arranged tong arm 3, following tong arm 5, automatic control device 2, described upward tong arm 3, following tong arm 5 every ends are two one group, are hinged to flexible caliper unit by adapter shaft.
The tong arm 3 one end tie-beam axles 7 of going up described in the utility model, the other end is provided with chute, and connect an end of tong arm 5 down by chute by adapter shaft 9, and wherein automatic control device 2 one ends are connected the middle part of tong arm 3 on by adapter shaft 8, and the other end is connected on another on tong arm 3 by spring 4.Described tong arm 5 is arranged in a crossed manner down, by adapter shaft 10 two following tong arms 5 is linked together, and the lower end of following tong arm 5 also is provided with jaw 6.Described automatic control device 2 comprises fan-shaped block 11, bayonet lock 12, and wherein fan-shaped block 11 is that rotate at the center with the summit, and bayonet lock 12 slides in groove.
The switching power of the gripping power of the utility model clamping plate slab and switching clamp does not need external force, during the work of lifting gripping mechanism, utilize the crane lifting gripping mechanism, the gripping power of clamp clamping plate slab is that the weight by plate slab itself produces by leverage, by the clamping of automatic control device (sliding gravity recloser) control steel billet with unload and put action.
During the utility model work, utilize the crane lifting gripping mechanism, the gripping power of clamp clamping plate slab is that the weight by plate slab itself produces by leverage, by the clamping of automatic control device (sliding gravity recloser) control steel billet with unload and put action.The lubricating method of clamp bearing is a grease lubrication.
The utility model working process:
1, picks up weight
Be in light condition before the clamp work, this timed unit is positioned at Fig. 3 state position, and clamp desires to pick up first weight, then slowly drops to the first weight height and position.When grip finger brushed up against weight, the clamp structure quadrangle was owing to the deadweight effect deforms, and jaw broadens, and it is flat that quadrangle becomes, to the bayonet lock in the automatic control device bayonet socket is skidded off to the right along bayonet socket, up to position shown in Fig. 4 state.This moment, fan-shaped block changeed down because of the deadweight cw, blocked bayonet socket.This moment, then clamp can begin to rise, because bayonet socket is plugged if suspended object has been arranged in jaw, bayonet lock can not be slided back in the bayonet socket again, continues to clamp suspended object to moving to left up to jaw but cross bayonet socket, this timed unit is positioned at position shown in Fig. 5 state, finishes the lifting process.
2, discharge weight
When suspended object was put into the destination, whole sub-folder pincers continued to transferring, and owing to the deadweight effect, thereby made jaw decontrol weight, and it is big that opening continues to become.This moment, the clamp structure quadrangle deformed, and it is big that width becomes, and bayonet lock is slided to the right, promote fan-shaped block left-hand revolution, get back to position shown in Fig. 3 state (being stuck position), at this moment clamp will stop to descend, begin to rise,, promptly got back to light condition because jaw can not dwindle again.Finish once from picking up weight to the process that discharges weight, this is the automatic control process of clamp automatic control device.
The utility model the key technical indexes:
Specified heavy lift: 1000kg;
The highest clamping base temperature: 1250 ℃
Maximum grip width and minimum grip width poor: be not more than 400mm, this mechanism indoors, all can use outward
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; do not breaking away under the preceding topic of the utility model design philosophy; engineering staff make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
