Abstract
The utility model provides a cargo boom of a lorry-mounted crane, which comprises a main boom and a lifting hook which is mounted on the cargo boom, wherein a telescopic boom is assembled in the front of the main boom and is connected with a corresponding telescopic oil cylinder; and the lifting hook is mounted on the telescopic boom. As the telescopic boom is assembled on the main boom of the cargo boom and the lifting hook is directly mounted on the telescopic boom, the cargo boom is convenient to mount, dismount and maintain; during lifting operation, the telescopic boom is directly retracted to a position near a heavy object, the positioning is accurate, and the operation is simple; the amplitude of swing of the heavy object is reduced, so that the lifting operation is safer and more reliable; and a windlass of the crane is omitted, and the lifting hook is directly mounted in a suspension arm (namely the telescopic boom), so that the time for the windlass to drop the lifting hook is saved, and the lifting operation is more convenient.
Description
Technical field
The utility model has related to a kind of lorry-mounted crane, relates in particular to a kind of crane arm of lorry-mounted crane.
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.According to lever principle, under the certain situation of pressure, fulcrum is far away more, and needed power is just more little.Lorry-mounted crane size owing to its crane arm when lifting job is fixed; Can only carry out handling to the goods of fixed distance; Has not extensibility; Can't carry out lifting job for the goods that exceeds crane arm or be less than in the boom length, greatly limit the lifting job scope of lorry-mounted crane.Traditional solution is that suspension hook is installed on the steel rope of winch, leans on winch pulling steel rope to realize lifting.If lifting needs long steel rope, weight will rock severity aloft, and is special in the winter of bad weather, makes the difficult of hoisting operation change.
The utility model content
The technical matters that the utility model will solve is in order to overcome technological deficiency recited above, a kind of novel lorry-mounted crane crane arm to be provided.
In order to solve technical matters recited above, the utility model is taked following technical scheme:
The utility model provides a kind of crane arm of lorry-mounted crane, includes principal arm, and is installed in the suspension hook on the crane arm, and said principal arm the place ahead is assembled with telescopic boom, and telescopic boom connects cooresponding telescopic oil cylinder, and described suspension hook is installed on the telescopic boom.
Described telescopic oil cylinder is arranged in the principal arm.
Said principal arm the place ahead is assembled with four layers of telescopic boom from inside to outside, and every layer of telescopic boom connects cooresponding telescopic oil cylinder, and described telescopic oil cylinder places in the principal arm, and described suspension hook is installed on the outermost telescopic boom.
The utility model is directly installed on suspension hook on the telescopic boom through on the principal arm of crane arm, assembling telescopic boom, and its installation, dismounting, maintenance are all very convenient.When carrying out lifting job, directly zoom to telescopic boom near the weight, accurate positioning, simple to operate.Reduce the amplitude that weight rocks aloft, make lifting job more safe and reliable! The winch of the utility model cancellation hoisting crane, the direct mount suspension hook is on arm.Need not wait for that winch transfers the time of suspension hook, make lifting job convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model instance one.
Fig. 2 is the structural representation of the utility model instance two.
Among the figure, 1. principal arm, 2. telescopic boom, 21. flexible arms, 22. flexible two arms, 23. flexible three arms, 24. flexible four arms, 3. telescopic oil cylinder, 4. suspension hook.
The specific embodiment
Embodiment one:
See also Fig. 1, as shown in the figure, the crane arm of lorry-mounted crane includes principal arm 1 and suspension hook 4, and principal arm 1 the place ahead is assembled with telescopic boom 2, and telescopic boom 2 connects cooresponding telescopic oil cylinder 3, and telescopic oil cylinder 3 is arranged in the principal arm 1, and suspension hook 4 is installed on the telescopic boom 2.
Embodiment two:
See also Fig. 2, as shown in the figure, the lorry-mounted crane crane arm includes the principal arm 1 and suspension hook 4 of crane arm; Principal arm 1 the place ahead is assembled with telescopic boom 2; This telescopic boom 2 includes four layers of telescopic boom that are assembled in principal arm 1 the place ahead from inside to outside, is respectively a flexible arm 21, flexible two arms 22, flexible three arms 23 and flexible four arms 24, and every layer of telescopic boom connects cooresponding telescopic oil cylinder 3; Telescopic oil cylinder 3 all places in the principal arm 1, and suspension hook 4 is installed on outermost flexible four arms 24.The utility model is directly installed on suspension hook on the telescopic boom through on the principal arm of crane arm, assembling telescopic boom, and its installation, dismounting, maintenance are all very convenient.When carrying out lifting job, directly zoom to telescopic boom near the weight, accurate positioning, simple to operate.
