Description
Technical field
The present invention relates to technical field of engineering machinery, be specifically related to a kind of automatic hook-retracting device for hoisting hook of intelligent lorry-mounted crane.
Background technology
The present situation of China's lorry-mounted crane and existence is not enough as follows at present:
1, kind is few, yields poorly, and China's lorry-mounted crane is in elementary development phase now, and kind is few, and medium and small tonnage repeats more, not yet forms so far large, medium and small complete series, and yearly output only is equivalent to the productive capacity of an external producer.
2, force moment of crane is little, and technical merit is low, and China's lorry-mounted crane is subjected to the restriction of domestic truck chassis take the straight-arm elevator as main.Hoisting moment is little, and other performance figure also generally are lower than external advanced product.At present domestic enterprise to the input in research and development of lorry-mounted crane seldom, the level of hydraulic efficiency pressure system, control system and international most advanced level also have a certain distance.
3, safety device is incomplete, inconvenient operation, and China's lorry-mounted crane only is equipped with the Generally Recognized as safe devices such as lifting altitude, spacing and balance cock, by pass valve, and all is M/C, and abroad already Eltec is widely used on the lorry-mounted crane.As with the limiter of moment of micro computer and anti-tipping protector etc., the realization that has wired and wireless remote control.
4, function singleness, China's lorry-mounted crane is take the hoisting operation transportation as main.And external lorry-mounted crane all has multiple attaching, and mainly is installed at the arm head.Pull fork, loading and unloading tire machinery hand, dial stake device etc. such as working bucket, grab bucket, high-altitude operation platform, gripping apparatus, hanging basket, auger.Make lorry-mounted crane possess the function of a tractor serves several purposes.
5, outward appearance is not attractive in appearance, and China's lorry-mounted crane appearance design and color are dull, have ignored the coordination with car conour.
6, load hook is without automatic hook collection device, after each hoisting operation is finished, load hook can not the automatic folding hook, can only lean on manually suspension hook is fixed on the fuselage, like this, when the manual control winch, steel rope is reserved too short then suspension hook and is not fixed, and steel rope is reserved long, and then steel rope swings, fixing not firm, impact safety and practicality in transit.
Summary of the invention
Technical matters to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of automatic hook-retracting device for hoisting hook of intelligent lorry-mounted crane, as long as stir a special hydraulic control lever, just can make load hook automatically pack up and automatically stop, automatically fixing, operate light, laborsaving, safe and reliable, do not wave, do not block driving sight, save cargo bay, promote technical performance and the quality of lorry-mounted crane.
The technical solution used in the present invention is: the suspension hook assembly of this automatic hook-retracting device for hoisting hook of intelligent lorry-mounted crane is connected with the reel assembly by steel rope, the reel assembly is again by the transmission of elevator oil motor, on the little arm assembly of boom assembly guide plate is installed, on the top of boom assembly limit switch and lockable mechanism are installed, lockable mechanism connects the control limit switch, and the electromagnetic valve of limit switch control elevator oil motor, be equipped with on the suspension hook assembly and receive the hook positioning hanger, receive the hook positioning hanger and bump lockable mechanism and limit switch, receive hook positioning hanger cover and hang on the lockable mechanism.
In the technique scheme, described lockable mechanism comprises fixed support, swing connecting bar, small rod, the fixed support upper end is fixed on the boom assembly, the fixed support lower end connects swing connecting bar by the first bearing pin, swing connecting bar one end is equipped with hanger pin, the receipts hook positioning hanger of hanger pin cover hanging hook assembly, the other end of swing connecting bar connects small rod by the second bearing pin, and small rod connects the control limit switch.
In the technique scheme, described limit switch comprises upper contact, lower contact, backguy and retracing spring, and retracing spring is installed between upper contact and the lower contact, and the backguy upper end connects upper contact, and the backguy lower end connects the small rod of lockable mechanism.
In the technique scheme, after swing connecting bar one end is equipped with hanger pin, consist of " H " shape.
In the technique scheme, described suspension hook assembly upper end is equipped with track adjusting wheel, and corresponding with it, the guide plate side is arc, and the arc-shaped side edges of guide plate is connected and installed with dash plate and bump rubber by attachment bolt.
The automatic hook-retracting device for hoisting hook of intelligent lorry-mounted crane principle: open corresponding change-over valve; roll up on the elevator; steel rope 8 drives suspension hook assembly 2 and rises; track adjusting wheel 9 when rising to certain position in the suspension hook assembly 2 contacts with dash plate 13 in the guide plate 10; bump rubber 12 compressions; reduced like this impulsive force when track adjusting wheel 9 contacts with guide plate 10, actv. has been protected guide piece.Suspension hook assembly 2 continues to rise, track adjusting wheel 9 is with the guide groove track pulsation-free upward movement of guide plate 10, contact with lockable mechanism 6 when rising to certain position rear hanger assembly 2, lockable mechanism 6 is with drop-down limit switch 3 closures that make of limit switch upper contact, it is electric that thereby corresponding electromagnetic valve gets, cut off the oil-feed oil circuit of hoisting mechanism, it is quit work, lockable mechanism 6 is also with 2 lockings of suspension hook assembly simultaneously.
Advantageous effect: when the present invention will be in off working state at hoisting crane, automatically suspension hook is packed up and be fixed up, to avoid waving or the generation of accident.This automatic hook collection device only need be stirred a special hydraulic control lever, just can make suspension hook pack up and be fixed on the below of arm, makes it not wave, and can increase the cargo bay of autotruck loading space.When arm places the operator's compartment front, also can avoid blocking the sight line of driving the driver, greatly strengthened safety and practicality in transit.
Load hook of the present invention is received hook, only need stir a special hydraulic control lever and load hook can be received automatically the work of fixing and stopping oil circuit, the safety hazard such as driving sight have been avoided waving, have blocked, and can increase the cargo bay of autotruck container, the present invention is simple to operate, and is easily, laborsaving, degree of automation is high, has greatly promoted technical performance and the quality of lorry-mounted crane.
