The electric lifting device is characterized by comprising stand columns, a lifting frame, diagonal supports and an electric chain type hoist, wherein a plurality of stand columns are distributed at the periphery of the inner wall of a large steel cylindrical shell, the lifting frame is arranged at the tops of the stand columns, the electric chain type hoist is arranged on one side, facing the inner wall of the shell, of the lifting frame, the diagonal supports are arranged on the sides, opposite to the shell, of the stand columns, the bottoms of the stand columns and the diagonal supports are all connected with a tank bottom plate, a lifting lug is arranged at the position close to the lower part of the inner wall of the shell, and a lifting hook of the electric chain type hoist and the lifting lug are connected. Compared with the prior art, the electric lifting device has the beneficial effects of meeting the lifting requirement of a large steel cylindrical shell construction site, being capable of completing the installation operation without the use of large hoisting equipment, lowering the operation cost, reducing the labor intensity, improving the working efficiency by two to three times, ensuring the safety and the quality of the installation operation, especially applicable to the situations of relatively narrow construction operation fields.
Description
Technical field
The utility model relates to large-sized steel cylindrical housings engineering construction field, particularly a kind of electric lifting device.
Background technology
At present, along with the fast development of steel structure specialty, especially oil, chemical industry; thin-walled, the application of large diameter steel circular cylindrical cylindrical shell are more and more extensive; larger for this diameter; wall thickness is thinner, the installation work construction of the steel circular cylindrical housing that integral rigidity is weak, must be used Large-scale Hoisting equipment to carry out operation.Work as narrow field, when large-scale hoisting facilities cannot be put to good use, conventional construction method cannot guarantee the safety of operation, therefore in order to improve operating efficiency and quality, the process modification of Steel Structure Installation is proposed to new problem.
Summary of the invention
The purpose of this utility model is to provide a kind of electric lifting device, in the engineering construction of large-sized steel cylindrical housings, can guarantee that housing promotes the safety of operation, is particularly useful for narrow field occasion, reduces operating cost, improves operating efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of electric lifting device, comprise column, raising legs, diagonal ligament and electric chain hoist, a plurality of columns are along large-sized steel cylindrical housings inwall circumference, 2～5 meters of adjacent spacing, described column and inner walls spacing are not more than 300mm, column top is provided with raising legs, on raising legs, towards inner walls side, be provided with electric chain hoist, described column dorsad case side is provided with two diagonal ligaments along column axis is symmetrical, described column is all connected with tank bottom with the bottom of diagonal ligament, inner walls on the lower position is provided with hanger, the suspension hook of electric chain hoist is connected with hanger.
The seam that the corresponding adjustment ring of described inner walls is installed is provided with door frame, establishes puller bolt on door frame.
Prior art is compared, and the beneficial effects of the utility model are:
Met the requirement of large-sized steel cylindrical housings camp site lifting, without using Large-scale Hoisting equipment can complete installation exercise, reduced operating cost, reduced labour intensity, can improve 2～3 times of work efficiency, guarantee safety and the quality of installation exercise, be particularly useful for the narrower and small occasion in construction operation place.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
See Fig. 1, it is a kind of electric lifting device example structure of the utility model schematic diagram, comprise column 1, raising legs 2, diagonal ligament 4 and electric chain hoist 6, a plurality of columns 1 are along the columniform housing 3 inwall circumference of large-sized steel, 2～5 meters of adjacent spacing, column 1 is not more than 300mm with housing 3 inwall spacing, moment of flexure while promoting to reduce, column 1 top is provided with raising legs 2, on raising legs 2, towards inner walls side, be provided with electric chain hoist 6, column 1 dorsad case side is provided with two diagonal ligaments 4 along column axis is symmetrical, prevent that column from tilting, guarantee its stability, column 1 is all connected with tank bottom 11 with the bottom of diagonal ligament 4, with spirit level or line pendant, measure the squareness of column, column 1 is arranged on the plain place of tank bottom 11, tank bottom 11 and column bottom are all should note real, tank bottom 11 is provided with reinforced rib 10, to improve its intensity, housing 3 inwalls on the lower position are provided with hanger 5, and the suspension hook of electric chain hoist 6 is connected with hanger 5.
The seam that the corresponding adjustment rings 7 of housing 3 inwalls are installed is provided with door frame 8, establishes puller bolt 9 on door frame 8, adopts puller bolt 9 to hold out against assembly welding after adjustment ring 7 completes out of roundness, and deflection appears when preventing from promoting in the installation application level pipe levelling of adjustment ring.
See Fig. 2, in the utility model, the power supply of a plurality of electric chain hoists 6 is controlled and is connected on same source switch, each electric chain hoist 6 must same model, consistent, the same producer of no-load speed is through being up to the standards, can use, to realize a key control, start lifting simultaneously, accomplishing acts in agreement as far as possible guarantees that each is consistent to hoisting speed, the welding that should note checking each position hanger 5 and column 1 on housing 3, diagonal ligament 4, tank bottom 11 while simultaneously promoting is all right, after the operating mode of each electric chain hoist 6 confirmation is simultaneously safe and reliable, can promote.
