Description
Technical Field
The application relates to the field of automobile cranes, in particular to an angle compensation arm suitable for an automobile crane telescopic arm.
Background
The automobile crane is one kind of crane installed on common or special automobile chassis and has driving cab separated from the crane control cab. The crane has the advantages of good maneuverability and rapid transfer. The chassis performance of the automobile crane is equal to that of a lorry with the same total weight of the whole automobile, and the automobile crane meets the technical requirements of road vehicles, so that the automobile crane can pass through various roads without resistance.
The lifting hook is generally installed on the top end of the telescopic arm of the existing automobile crane, so that the goods are conveniently lifted, and the existing automobile crane sometimes encounters special conditions, the length of the telescopic arm is not enough, the goods can not be lifted at a right angle, the goods can not be well lifted, and the operation time is increased or the goods can not be damaged carelessly.
Disclosure of Invention
To the above problem, the technical scheme of the utility model is: the utility model provides an angle compensation arm suitable for mobile crane arm that stretches out and draws back, its constitution includes flexible arm and installs the lifting hook fixing base one at flexible arm left end, and lifting hook, its characterized in that are installed to lifting hook fixing base below: the telescopic boom is of a hollow structure with an open left end, an angle compensation boom is slidably mounted at the left end of the telescopic boom, a second lifting hook fixing seat with a downward inclination is fixedly mounted at the left end of the angle compensation boom, a lifting hook mounting hole is formed in the left end of the second lifting hook fixing seat, limiting plates are symmetrically arranged on the two sides of the left end of the first lifting hook fixing seat respectively, a first limiting hole is formed in each limiting plate, a second limiting hole and a third limiting hole are formed in each end of the angle compensation boom corresponding to the first limiting hole respectively, and a limiting bolt is arranged on the first limiting hole.
The utility model has the advantages that:
1. when the automobile crane lifts the goods and needs to use the angle compensation arm, the limiting bolt can be pulled out, then the angle compensation arm is pulled out towards the left side, and then the telescopic arm and the angle compensation arm are fixed together through the limiting bolt, so that the purpose of extending the telescopic arm is achieved, and the goods can be lifted conveniently.
2. The utility model has simple structure, convenience and practicality, and convenient maintenance; even the angle compensation arm can be wholly pulled out and turned over by 180 degrees and then inserted into the telescopic arm for use, and the effects of extending the telescopic arm and compensating the angle can be achieved.
Drawings
Fig. 1 is a schematic structural view of the present invention in an extended state.
Fig. 2 is a schematic structural diagram of the contraction state of the present invention.
In the figure: the telescopic boom comprises a telescopic boom 1, a first lifting hook fixing seat 2, a limiting plate 3, an angle compensation boom 4, a limiting bolt 5, a second limiting hole 6, a second lifting hook fixing seat 7, a lifting hook mounting hole 8 and a lifting hook 9.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
In fig. 1 and 2, an angle compensation arm suitable for mobile crane telescopic boom, its constitution includes telescopic boom 1 and installs lifting hook fixing base 2 at telescopic boom 1 left end, and lifting hook 9, its characterized in that are installed to lifting hook fixing base 2 below: the telescopic arm 1 is of a hollow structure with an open left end, an angle compensation arm 4 is slidably mounted at the left end of the telescopic arm 1, a lifting hook fixing seat II 7 with a downward inclination is fixedly mounted at the left end of the angle compensation arm 4, a lifting hook mounting hole 8 is formed in the left end of the lifting hook fixing seat II 7, limiting plates 3 are symmetrically arranged on the left end and the left end of a lifting hook fixing seat I2 respectively, a first limiting hole is formed in each limiting plate 3, two ends of the angle compensation arm 4, corresponding to the first limiting hole, are provided with a second limiting hole 6 and a third limiting hole respectively, and a first limiting bolt 5 is arranged on the first limiting hole.
When angle compensation arm 4 is used to needs, extract limiting bolt 5 earlier, pull out angle compensation arm 4 to the left side again, until the spacing hole three of angle compensation arm 4 right-hand member and the spacing hole one coincidence on the limiting plate 3, will then fix flexible arm 1 and angle compensation arm 4 together through limiting bolt again to reach the purpose that the flexible arm of extension and compensation lifted by crane the angle, install lifting hook 9 on lifting hook mounting hole 8 again. When the angle compensation arm is not used, the limiting bolt 5 is pulled out, the angle compensation arm 1 is pushed rightwards, the right end part of the angle compensation arm 1 is pushed into the hollow structure of the telescopic arm 1, and the limiting bolt 5 is inserted after the limiting hole II 6 at the left end of the angle compensation arm 4 is overlapped with the limiting hole I on the limiting plate 3, so that the purpose of fixing the angle compensation arm 1 is achieved. Even the angle compensation arm 4 can be wholly pulled out and turned over for 180 degrees and then inserted into the telescopic arm 1 for use, and the effects of extending the telescopic arm 1 and compensating the angle can be achieved.
