Abstract
The utility model relates to a tool for transmission and transformation electric power circuit construction, in particular to a suspension arm for a 400 KN crane. The suspension arm comprises a main arm and an assistant arm which are mounted at the tail end of the crane, wherein both the main arm and the assistant arm are formed by splicing 2 to 4 sections of unyielding props; the end parts of the unyielding props are hinged with the root of the assistant arm; a swing mechanism is mounted in the hinged part; and lifting hooks are mounted at both the root and the end of the assistant arm. Through suspension arm has the advantages that the maximum lifting capability is 400 KN; the rated maximum lifting capability can meet the requirements of large size and large lifting capability for the assembly of an iron tower; a locking pin is additionally arranged in the swing mechanism, so as to control the swing of the suspension arm when the crane is in a driving state; the anti-shock property is excellent; the structure is firm; and the safety is high.
Description
Technical field
The utility model relates to the Work tool that uses in the power transmission and transformation power line construction, relates in particular to the arm that in the upright process of extra-high voltage large crossing tower group, lifts tower leg and the 400KN crane that uses in the pole construction is installed.
Background technology
In the large-scale steel structure electric power tower vertical construction process, generally need to adopt the pole hanging device, the upright iron tower of the body of the tower group of lifting iron tower; Wherein, the design and the Hoisting Program of suspender match, along with the continuous development of the construction of national grid; The engineering of crossing over large-scale rivers ocean is more and more, and the height of iron tower is increasing, and the scantling of iron tower is big, lift heavy is big; To safety and the higher requirement of specified lift heavy proposition that lifts tower leg and the suspension arm of crane of pole use is installed; Existing crane lifting radius is little, and specified maximum lift heavy is little, can not satisfy the lifting construction demand of big leap, high iron tower.
Summary of the invention
The purpose of the utility model is to solve the problem of above-mentioned existence, and the arm of the 400KN crane of the demand that a kind of sound construction, safety are good, big, the specified maximum lift heavy of lifting radius can satisfy the lifting of super large crossing tower is provided.
For realizing above-mentioned purpose; The arm of a kind of 400KN crane of the utility model design-calculated; Comprise the principal arm and the auxiliary that are installed in the crane afterbody, said principal arm and auxiliary are spliced by 2-4 section rigid support, and the end of said principal arm and the root of said auxiliary are hinged; In this hinged place swing type mechanism is installed, the root of said auxiliary and end all are equipped with suspension hook.
In technique scheme, on the said swing type mechanism stop pin is installed.
In technique scheme, auxiliary is 25 °-30 ° with respect to the change angle scope of principal arm.
The arm of the utility model design-calculated 400KN crane, principal arm and auxiliary are spliced by 2-4 section rigid support, and principal arm length can reach 10.6-33.7m; Auxiliary length can reach 9.8-17.1m, and the entire length of arm can satisfy the interior lifting requirements of scope of big distance, and arm is realized the operation luffing through amplitude oil cylinder; The maximum load-carrying ability 400kN of this product; Specified maximum lift heavy satisfies the lifting demand in the iron tower assembling process that size is big, lift heavy is big, has increased stop pin at swing type mechanism, the swing of arm when having controlled motoring condition; Have good resistance to shock in when operation revolution, sound construction, safety are good.
Description of drawings
Fig. 1 is the example structure scheme drawing of the utility model;
Among the figure: 1, principal arm, 2, auxiliary, 3, swing type mechanism, 4, suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The arm of 400KN crane as shown in Figure 1; Comprise that principal arm 1 and auxiliary 2 are spliced by 2-4 section rigid support; The root of the end of principal arm 1 and said auxiliary 2 is hinged, in this hinged place swing type mechanism 3 is installed, and the root of auxiliary 2 and end all are equipped with suspension hook 4.
Swing type mechanism 3 is made up of rotary supporting device and device for revolving and driving two parts, and rotary supporting device is bearing in the rotating part of hoisting crane on the fixed part, and device for revolving and driving driving rotational part is turned round with respect to fixed part.On the swing type mechanism 3 stop pin is installed, the swing of arm when having controlled motoring condition has good resistance to shock when the revolution operation, sound construction, safety factor height.Auxiliary 2 is 25 °-30 ° with respect to the change angle scope of principal arm 1.
During use, in carrying out pole installation and tower leg part hoisting process, lift pole bottom plurality of sections during the crane lifting pole earlier, make the pole bottom fixing on the pole basis.Lift the pole head simultaneously and dock with it, pole can be realized the pole jacking from elevating function through self afterwards.During the hypomere of crane lifting tower leg, the crane position begins lifting according to the needs displacement of hanging piece after fixing again, and transaction capabilities is good, and it is very convenient to operate.
