Abstract
The utility model discloses a hoisting arm, which comprises at least two 'L'-shaped arm bodies and bar-shaped limiting blocks. Each 'L'-shaped arm body comprises a transverse arm and a longitudinal arm by means of connection, transverse arms of each two adjacent 'L'-shaped arm bodies are fixed through fixing bars, and one end of each bar-shaped limiting block is hinged to the joint of the transverse arm and the longitudinal arm of each 'L'-shaped arm body. By the aid of the structure, the hoisting arm has the advantages that firstly, when transformers need to be loaded, loading can be facilitated by placing the transformers on the transverse arms of the hoisting arm firstly, placing cushion blocks among the transformers and the longitudinal arms of the hoisting arm, lifting up the bar-shaped limiting blocks, putting down the longitudinal arms of the hoisting arm, and finally lifting up the transformers by the transverse arms of the hoisting arm with the help of the lever principle; and secondly, three 'L'-shaped arm bodies are firmer.
Description
Technical field
The utility model relates to a kind of lifting arm.
Background technology
At present, in the production process of voltage transformer, high-power transformer needs entrucking when transporting.And voltage transformer leans on crane and manpower to lift on the transport trolley when entrucking, operating difficulties, and labor intensive is big, is prone to simultaneously high-power transformer is caused damage.
The utility model content
The utility model technical matters to be solved is to the deficiency of prior art, a kind of lifting arm that makes things convenient for the high-power transformer entrucking to be provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of lifting arm; Comprise " L " type arm body more than at least two, described " L " type arm body is connected and composed by transverse arm and trailing arm, is connected through fixed link between the transverse arm of described adjacent " L " type arm body; Described lifting arm also comprises the strip limiting stopper, and an end of described strip limiting stopper is hinged on the trailing arm of " L " type arm body and the junction of transverse arm.
Described " L " type arm body is 3.
The utility model adopts said structure, has the following advantages: in the time of 1, need be with the voltage transformer entrucking, earlier voltage transformer is placed on the transverse arm of lifting arm, and between the trailing arm of voltage transformer and lifting arm, puts cushion block.At this moment lift the strip limiting stopper, the lifting arm trailing arm was fallen, utilize lever principle promptly voltage transformer to be lifted, make things convenient for entrucking through the transverse arm of lifting arm; 2,3 " L " type arm bodies are more firm.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation;
Fig. 1 is the structural representation of the utility model;
In Fig. 1,1, transverse arm; 2, trailing arm; 3, fixed link; 4, strip limiting stopper.
The specific embodiment
A kind of lifting arm as shown in Figure 1; Comprise " L " type arm body more than at least two; " L " type arm body is connected and composed by transverse arm 1 and trailing arm 2; Be connected through fixed link 3 between the transverse arm 1 of adjacent " L " type arm body, lifting arm also comprises strip limiting stopper 4, and an end of strip limiting stopper 4 is hinged on the junction of the trailing arm 2 and the transverse arm 1 of " L " type arm body.
" L " type arm body is 3.3 " L " type arm bodies are more firm.In the time of need be with the high-power transformer entrucking, earlier voltage transformer be placed on the transverse arm 1 of lifting arm, and between the trailing arm 2 of voltage transformer and lifting arm, puts cushion block.At this moment lift strip limiting stopper 4, lifting arm trailing arm 2 was fallen, utilize lever principle promptly voltage transformer to be lifted, make things convenient for entrucking, when avoiding entrucking voltage transformer is caused damage through the transverse arm of lifting arm.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the technical scheme of the utility model to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
Claims (2)
1. lifting arm; It is characterized in that: comprise " L " type arm body more than at least two; Described " L " type arm body is connected and composed by transverse arm (1) and trailing arm (2); Be connected through fixed link (3) between the transverse arm (1) of described adjacent " L " type arm body, described lifting arm also comprises strip limiting stopper (4), and an end of described strip limiting stopper (4) is hinged on the trailing arm (2) of " L " type arm body and the junction of transverse arm (1).
