Description
Technical field
The utility model relates to the safety device of hoisting crane, particularly a kind of suspension hook fixed-guard of lorry-mounted crane.
Background technology
Lorry-mounted crane refers to and is arranged on car chassis, within the specific limits many actions elevator machinery of vertical-lift and horizontal carrying heavy goods.Along with social progress, lorry-mounted crane is more and more widely used in industry-by-industry.Wherein use the most extensive with flexible winding type lorry-mounted crane again.But flexible winding type lorry-mounted crane is when vehicle travels, and the suspension hook of its arm body bottom is in transitory state, always swings back and forth, very dangerous, and drives steel rope heel and toe wear, has a strong impact on service life.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, a kind of suspension hook fixed-guard of lorry-mounted crane is provided, safe for suspension hook safety is fixed on telescopic boom body bottom by this device, when so both avoiding vehicle traveling, suspension hook is not fixed, swing back and forth the safety problem caused, and solves again the heel and toe wear of steel rope, makes longer service life, the operation of final hoisting crane is safer, uses more reliable.
The technical solution of the utility model is by realizing as follows: a kind of suspension hook fixed-guard of lorry-mounted crane comprises telescopic boom body, side plate, suspension hook, cover of wedge, axle, rope wedge, steel rope, bearing pin, roller, hook, backing pin; It is characterized in that: it is inner that cover of wedge is fixed on telescopic crane boom body by axle, wirerope-winding is on rope wedge, and rope wedge is arranged on cover of wedge inside, and the steel rope of cover of wedge outside is fixed with rope clamp, and steel rope is connected with suspension hook through steel rope block.Telescopic boom body both sides are by bearing pin fixed side, and there is bias at the sheave shaft center on bearing pin center and telescopic boom body in the horizontal direction, and roller is arranged in the middle of side plate.Install hook on the top of suspension hook, one end of hook tilts, and the other end is fixed by extension spring, is provided with backing pin below at hook.
The beneficial effects of the utility model: safe for suspension hook safety is fixed on telescopic boom body bottom by this device, when both having avoided vehicle traveling, suspension hook is not fixed, swing back and forth the safety problem caused, solve again the heel and toe wear of steel rope, make longer service life, the operation of final hoisting crane is safer, uses more reliable.

Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Structural representation when Fig. 3 is the utility model receipts hook.
In figure: 1. telescopic boom body, 2. side plate, 3. link up with, 4. suspension hook, 5. cover of wedge, 6. axle, 7. restrict wedge, 8. steel rope block, 9. rope clamp, 10. extension spring, 11. backing pins, 12. sheave shafts, 13. bearing pins, 14. rollers, 15. steel ropes.
Detailed description of the invention
With reference in Fig. 1, Fig. 2 and Fig. 3, the utility model comprises telescopic boom body 1, side plate 2, hook 3, suspension hook 4, cover of wedge 5, axle 6, rope wedge 7, bearing pin 13, roller 14, extension spring 10, backing pin 11, steel rope 15; It is inner that cover of wedge 5 is fixed on telescopic crane boom body 1 by axle 6, and steel rope 15 is wrapped on rope wedge 7, and it is inner that rope wedge 7 is arranged on cover of wedge 5, and cover of wedge 5 outer wires rope 15 is fixed with rope clamp 9, and steel rope 15 is connected with suspension hook 4 through steel rope block 8.Telescopic boom body 1 both sides are by bearing pin 13 fixed side 2, and there is bias at bearing pin 13 center in the horizontal direction with sheave shaft 12 center on telescopic boom body 1, and roller 14 is arranged on side plate 2 centre.Install hook 3 on the top of suspension hook 4, one end of hook 3 tilts, and the other end is fixed by extension spring 10, is provided with backing pin 11 below at hook 3.
Its principle of work is: hoisting crane is when receiving suspension hook 4, and hook 3 constantly rises with suspension hook 4, and when hook 3 rises to bottom touching side plate 2, one end is depressed, and the other end lifts, and hangs over bottom side plate 2.Suspension hook 4 continues to pack up, and side plate 2 is stressed to be overturn centered by bearing pin 13, drives suspension hook 4 to overturn together, until reach regulation flip angle.Hoisting crane is when putting suspension hook 4, steel rope 15 constantly extends, distance between pulley 12 and suspension hook 4 becomes large gradually, by the effect that suspension hook 4 is conducted oneself with dignity, suspension hook 4 centered by bearing pin 13, returns to plumbness with side plate 2 gradually, extension spring afterwards 10 pulls bottom hook 3 and side plate 2 throws off, side plate 2 is separated with suspension hook 4, and suspension hook 4 can continue to fall, and finally completes and puts suspension hook 4 action.
