Abstract
The utility model disclose a kind of can the straight arm type lorry-mounted crane of tilt angled down, include the column turntable be fixed on wrecker, the top of column turntable is hinged with telescopic boom, the oil cylinder driving telescopic boom to swing up and down is hinged with between column turntable and telescopic boom, the telescopic end of telescopic boom is provided with suspension hook, suspension hook is in order to lift crane suspender, described column turntable is fixed on the elevation-over of the vehicle-carrying plate of wrecker, the height of the cylinder body of oil cylinder is lower than the height of column turntable, and the height that the piston rod of oil cylinder stretches out exceeds the height of column turntable.What the telescopic boom of hoisting crane was set as by the utility model can tilt angled down operation, to can be used to the broken-down vehicle on road or roadbed or disabled vehicle fast, safety, hangs on the flat board of wrecker without passive safety, shipped off-site, guarantee the coast is clear.
Description
Technical field
The utility model relates to the special straight arm type lorry-mounted crane of specifically a kind of wrecker, to can be used to the broken-down vehicle on road or roadbed or disabled vehicle fast, safety, hangs on the flat board of wrecker without passive safety, shipped off-site, guarantee the coast is clear.The utility model is particularly useful for road obstacle clearing vehicle.
Background technology
Lorry-mounted crane is a kind of general crane truck, and its arm has straight arm type and folding-jib two profiles formula, and straight arm type lorry-mounted crane operating speed is fast, performance high energy, cost performance are high, is more suitable on wrecker than folding-jib.To order, domestic general straight arm type lorry-mounted crane, the most low angle of arm be all 0 degree (level) or positive-angle and steel rope, capstan winch are housed, when wanting hoisting heavy, by swinging, arm is upper and lower, left and right angle, telescoping boom, makes suspension hook just locate above weight, is sling by weight with capstan winch folding and unfolding steel rope.0 degree general, the most low angle of straight arm type suspension arm of lorry-mounted crane is just enough, if there is tilt angled down, also likely encounters the loading space breast board of lorry, has tilt angled down so also do not permit.General straight arm type lorry-mounted crane is used on wrecker two problems: one is lift by crane dolly with steel rope, there will be phenomenon of swinging, has a strong impact on operating speed, dolly of also easily damaging because of carelessness; Two be every subjob tie up hang steel rope to spend many time, had a strong impact on remove obstacles rescue operating speed.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of operating speed and the safety that improve wrecker, reduces the straight arm type lorry-mounted crane of passive safety.
For solving the problems of the technologies described above adopted technical scheme: a kind of can the straight arm type lorry-mounted crane of tilt angled down, include the column turntable be fixed on wrecker, the top of column turntable is hinged with telescopic boom, the oil cylinder driving telescopic boom to swing up and down is hinged with between column turntable and telescopic boom, the telescopic end of telescopic boom is provided with suspension hook, suspension hook is in order to lift crane suspender, it is characterized in that: described column turntable is fixed on the elevation-over of the vehicle-carrying plate of wrecker, the height of the cylinder body of oil cylinder is lower than the height of column turntable, the height that the piston rod of oil cylinder stretches out exceeds the height of column turntable.
Adopt the beneficial effect that brings of the utility model: what the telescopic boom of hoisting crane was set as by the utility model can tilt angled down operation, to can be used to the broken-down vehicle on road or roadbed or disabled vehicle fast, safety, hang on the flat board of wrecker without passive safety, shipped off-site, ensures the coast is clear.During lifting dolly, due to the operation of arm energy tilt angled down, without the need to adopting wireline winch to carry out crane, can directly dolly be sling by oil cylinder lifting telescopic boom with crane suspender.Reduce widely and swing phenomenon and save time of binding steel rope, greatly increase operating speed and the safety of rescue of removing obstacles, decrease the chance of passive safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model straight arm type lorry-mounted crane when tilt angled down operation;
Fig. 2 is the structural representation of the utility model straight arm type lorry-mounted crane when dolly being hung on wrecker.
Detailed description of the invention
As shown in Figure 1-2, a kind of can the straight arm type lorry-mounted crane of tilt angled down, include the column turntable 2 be fixed on wrecker 1, the top of column turntable 2 is hinged with telescopic boom 3, the oil cylinder 4 driving telescopic boom 3 to swing up and down is hinged with between column turntable 2 and telescopic boom 3, the telescopic end of telescopic boom 3 is provided with suspension hook 5, and suspension hook 5 is in order to lift crane suspender 6.In the utility model, described column turntable 2 is fixed on the elevation-over of the vehicle-carrying plate 7 of wrecker 1, the height of the cylinder body of oil cylinder 4 is lower than the height of column turntable 2, the height that the piston rod of oil cylinder 4 stretches out exceeds the height of column turntable 2, and such oil cylinder 4 just can drive telescopic boom 3 just can tilt angled down operation.
Telescopic boom 3 can be set as the multi-joint telescoping such as two joints, three joints.Column turntable 2 is built with the swing type mechanism be made up of pivoting support bearing and fluid motor-driven, and operating hydraulically operated motor just can make column turntable 2 drive telescopic boom 3 left-right rotation.Suspension hook 5 can 360 ° of rotations, make telescopic boom 3 can hang up crane suspender 6 in any angle.Crane suspender 6 can be firmly linked with dolly fast, and only contacts the rubber of vehicle tyre in the operation of lifting dolly, can not damage rigidity parts and the paint face of dolly.
