Description
Technical field
The utility model relates to the anchor fitting that a kind of hoisting crane overwinding-proof is raised protector and suspension hook, particularly a kind of lorry-mounted crane overwinding-proof hook fixing device.
Background technology
Lorry-mounted crane is meant and is installed on the car chassis, within the specific limits many actions elevator machinery of vertical-lift and horizontal carrying heavy goods.Along with social progress, the increasing industry-by-industry that is widely used in of lorry-mounted crane.Wherein use the most extensive with flexible winding type lorry-mounted crane again.But flexible winding type lorry-mounted crane is when vehicle ', and the suspension hook of its arm head bottom is in the on-fixed state, always swings back and forth, and is very dangerous, and drives the steel rope heel and toe wear, influences service life.On the other hand, existing hoisting crane overwinding-proof is raised device and is adopted weight to drag the alarm switch form, and its weight also has certain distance apart from arm head, suspension hook is risen be raised to maximum height, has influenced the crane job height.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of lorry-mounted crane overwinding-proof hook fixing device is provided, and overwinding-proof is raised annunciator to this device and the suspension hook anchor fitting is integrated; Can guarantee that elevator can pulleying not damage hoisting crane, suspension hook is risen be raised to bigger height, and solve the fixing problem of suspension hook in the vehicle ' process; Finally make the operation height of hoisting crane higher; Operate saferly, use more reliably, the life-span is longer.
The technical scheme of the utility model is through following realization: a kind of lorry-mounted crane overwinding-proof hook fixing device comprises telescopic boom body, suspension hook, carves cover, rope is carved, electric wire, bearing pin, suspension hook anchor fitting, contact switch, winder, electromagnetic valve, steel rope; It is characterized in that: carve and overlapped axle to be fixed on the telescopic crane boom body inner; Steel rope is wrapped in rope and carves; Rope is carved to be installed in and is carved cover inside, carves on the exterior steel rope of cover and is fixed with rope clamp, and steel rope is connected with suspension hook through bearing pin.Be provided with the suspension hook anchor fitting on the top of suspension hook, the suspension hook anchor fitting is separately fixed on the baffle plate of sheave shaft both sides.The suspension hook anchor fitting is made up of baffle plate, fixed cover, slide-bar, spring and bolt, nut.Inside at fixed cover is equipped with slide-bar, and slide-bar is connected through bolt with fixed cover, and between slide-bar and the fixed cover spring is installed.Contact switch is fixed on suspension hook anchor fitting one side, and through electric wire, winder and be fixed on the electromagnetic valve that elevator hoists on the oil pipe and be connected.
Its technical scheme that adopts is: hoisting crane is when receiving suspension hook, and suspension hook constantly rises, and touches slide-bar in the suspension hook anchor fitting when suspension hook rises to, and slide-bar is by jack-up, and the compression contained spring produces counter-force, tightens fixedly suspension hook.When suspension hook rises to touching during contact switch, contact switch is through electric wire, winder, the control electromagnetic valve switching-over, thus by the elevator oil circuit that hoists, make suspension hook can not continue to rise, finally prevent the winch pulleying.
The beneficial effect of the utility model: overwinding-proof is raised annunciator to this overwinding-proof hook fixing device and the suspension hook anchor fitting is integrated; Can guarantee can not damage hoisting crane because of the elevator pulleying; Can increase the suspension hook lifting altitude again, and solve the fixing problem of suspension hook in the vehicle ' process.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the mounting structure scheme drawing of the utility model in lorry-mounted crane.
Fig. 2 is the telescopic boom end structure for amplifying scheme drawing of Fig. 1.
Fig. 3 is the suspension hook anchor fitting structure for amplifying scheme drawing of Fig. 1.
Fig. 4 raises control linkage structure for amplifying scheme drawing for the overwinding-proof of Fig. 1.
Among the figure: the 1-telescopic boom body, the 2-suspension hook, the 3-winder, the 4-hydraulic winch, the 5-electromagnetic valve, 6-carves cover; The 7-axle, the 8-rope is carved 9-suspension hook anchor fitting, 10-contact switch, 11-electric wire, 12-bearing pin; The 13-rope clamp, 14-steel rope, 15-baffle plate, 16-sheave shaft, 17-nut; 18-fixed cover, 19-spring, 20-slide-bar, 21-bolt, the 22-elevator oil pipe that hoists.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model comprises telescopic boom body 1, suspension hook 2, carve cover 6, rope carves 8, electric wire 11, bearing pin 12, suspension hook anchor fitting 9, contact switch 10, winder 3; Electromagnetic valve 5, steel rope 14; It is characterized in that: carve cover 6 and cross axle 7 and be fixed on telescopic crane boom body 1 inside, steel rope 14 is wrapped in rope and carves on 8, and rope is carved 8 and is installed in and carves cover 6 inside; Carve on the cover 6 exterior steel ropes 14 and be fixed with rope clamp 13, steel rope 14 is connected with suspension hook 2 through bearing pin 12.Be provided with suspension hook anchor fitting 9 on the top of suspension hook 2, suspension hook anchor fitting 9 is separately fixed on the baffle plate 15 of sheave shaft 16 both sides.Suspension hook anchor fitting 9 is made up of baffle plate 15, fixed cover 18, slide-bar 20, spring 19 and bolt 21, nut 17.In the inside of fixed cover 18 slide-bar 20 is installed, slide-bar 20 is connected through bolt 21 with fixed cover 18, and between slide-bar 20 and the fixed cover 18 spring 19 is installed.Contact switch 10 is fixed on suspension hook anchor fitting 9 one sides, and through electric wire 11, winder 3 and be fixed on the electromagnetic valve 5 that elevator hoists on the oil pipe 22 and be connected.
Its principle of work is: hoisting crane is when regaining suspension hook 2, and suspension hook 2 constantly rises, and touches slide-bar 20 in the suspension hook anchor fitting 9 when suspension hook 2 rises to, and slide-bar 20 is by jack-up compression contained spring 19, and spring 19 produces counter-forces, tightens suspension hook 2, and it can not be freely swung.When suspension hook 2 risings touched contact switch 10, contact switch 10 was through electric wire 11,5 switching-overs of winder 3 control electromagnetic valve, thereby the oil circuit in elevator hoists oil pipe 22 makes suspension hook 2 can not continue to rise, and finally prevents hydraulic winch 4 pulleying.
