Abstract
A kind of suspension hook forced locking device, form primarily of winding box, electric wire, suspension hook, inhibiting device, guide plate, electrical equipment and Hydraulic Elements, HM Hydraulic Motor lower end has multiway valve B mouth and is communicated with hydraulic wireline winch with driving HM Hydraulic Motor connected sum multiway valve A mouth, HM Hydraulic Motor drives spool turns by gear transmission, steel rope connecting shackle on reel, suspension hook upper end arranges inhibiting device, be in extreme position topmost at suspension hook and be equipped with two pieces of guide plates, draw branch road in the middle of multiway valve and hydraulic wireline winch inside guide plate, branch road is connected to solenoid directional control valve and by pass valve.Branch road is drawn in the middle of the multiway valve of the utility model in ordinary lifting hook device and hydraulic wireline winch; on be connected to solenoid directional control valve and by pass valve; by pass valve is the operation pressure reducing this oil circuit at this radical function; suspension hook is better locked and better protects steel rope not to be pulled off; thus safety completes suspension hook self-locking operation; minimizing personnel waste, and improve crane lifting service efficiency.
Description
Technical field
The present invention relates to a kind of suspension hook, specifically a kind of suspension hook forced locking device on hoisting crane.
Background technology
Lorry-mounted crane is a kind of hoisting aids equipment be fitted on goods carrying vehicle.The goods carrying vehicle of lorry-mounted crane is housed, is also called for short truck-mounted crane.In motion, the suspension hook of hoisting crane should be fixing, excessively swings damage steel rope or collide other article to prevent suspension hook.Therefore, operating personal is after each hoisting operation completes, all suspension hook to be fixed, main method is hung over by suspension hook on the steel rope that is connected with compartment or chock plate between suspension hook and arm, generally need two people to assist mutually just can complete, the personnel that cause waste and reduce with work efficiency.
During crane hook work, the hydraulic oil that propulsion source provides enters HM Hydraulic Motor by control cock, HM Hydraulic Motor is driven to do positive and negative rotary motion, then motor does positive and negative rotation through the driving band movable reel of drop-gear box, reel drives the retractable campaign of the steel rope be wrapped on it, thus drives the suspension hook installed on a steel cord to hoist or descending motion.When suspension hook rises to final end position, together with suspension hook can touch with the crane arm front end of hoisting crane, now, because motor works under rated pressure, the moment of torsion of output is very large, easily breaks steel rope, thus accidents caused.
Summary of the invention
The utility model provides a kind of work efficiency high for solving the problems of the technologies described above, and cost is low, safety, convenient, failure-free suspension hook forced locking device.
Technical solution adopted in the utility model is:
Suspension hook forced locking device forms primarily of winding box, electric wire, suspension hook, inhibiting device, guide plate, electrical equipment and Hydraulic Elements, HM Hydraulic Motor lower end has multiway valve B mouth and is communicated with hydraulic wireline winch with driving HM Hydraulic Motor connected sum multiway valve A mouth, HM Hydraulic Motor drives spool turns by gear transmission, steel rope connecting shackle on reel, suspension hook upper end arranges inhibiting device, be in extreme position topmost at suspension hook and be equipped with two pieces of guide plates, draw branch road in the middle of multiway valve and hydraulic wireline winch inside guide plate, branch road is connected to solenoid directional control valve and by pass valve.
Advantage of the present utility model and good effect are:
Branch road is drawn in the middle of the multiway valve of the utility model in ordinary lifting hook device and hydraulic wireline winch; on be connected to solenoid directional control valve and by pass valve; suspension hook rises and is raised to certain altitude; solenoid directional control valve receives electric signal; electromagnetic valve is opened; high pressure oil flows to by pass valve by solenoid pilot valve; by pass valve is the operation pressure reducing this oil circuit at this radical function; suspension hook is better locked and better protects steel rope not to be pulled off; thus safety completes suspension hook self-locking operation; minimizing personnel waste, and improve crane lifting service efficiency.

Detailed description of the invention
Suspension hook forced locking device is primarily of winding box 1, electric wire 2, suspension hook 3, inhibiting device 4, guide plate 6, electrical equipment and some Hydraulic Elements composition, HM Hydraulic Motor lower end has multiway valve B mouth 12 and is communicated with hydraulic wireline winch 7 with driving HM Hydraulic Motor connected sum multiway valve A mouth 11, HM Hydraulic Motor is rotated by gear transmission band movable reel 5, steel rope connecting shackle 3 on reel, suspension hook 3 upper end arranges inhibiting device 4, be in extreme position topmost at suspension hook 3 and be equipped with two pieces of guide plates 6, branch road is drawn in the middle of multiway valve 10 and hydraulic wireline winch 7, branch road is connected to solenoid directional control valve 8 and by pass valve 9.
High pressure oil also enters solenoid directional control valve 8 while entering hydraulic wireline winch 7, normally off is in when electromagnetic valve does not work, now suspension hook 3 does the motion that hoists normally, when 3, suspension hook is raised to certain altitude, inhibiting device 4 switch is opened after entering two pieces of guide plates 6, solenoid directional control valve 8 receives the electric signal that electrical equipment sends, electromagnetic valve is opened, now a part of high pressure oil continue to enter HM Hydraulic Motor and another part high pressure oil by solenoid directional control valve 8, flow to by pass valve 9, after pressure is greater than the response pressure of by pass valve 9 setting, by pass valve 9 is opened, overflow, the operation pressure of this oil circuit is reduced to the response pressure of by pass valve 9.And now suspension hook 3 and inhibiting device 4, not by tightly locked, also have certain space, the pressure oil through step-down continues to drive HM Hydraulic Motor to rotate, and makes suspension hook 3 and inhibiting device 4 tightly locked.
