Technical Field

[0001] The utility model relates to the technical field of steel truss assembly devices, in particular to a construction device for controlling the assembly precision of large-span special-shaped steel trusses. Background Technique

[0002] A steel truss refers to a truss made of steel. The roof structures, crane beams, bridges, and hydraulic gates of industrial and civil buildings commonly use steel trusses as the main load-bearing members. Various types of tower structures, such as mast towers, television towers, and transmission line towers, commonly use space steel trusses composed of three-sided, four-sided, or multi-sided planar trusses.

[0003] During the assembly of existing large-span special-shaped steel trusses, the sub-trusses to be assembled are hoisted to the welding points connected to the main truss by hoisting, and then welded after hoisting to achieve the assembly of the sub-truss and the main truss. In the above method, during the hoisting process, workers need to manually control the landing position of the sub-truss by pulling ropes. This method not only has low control precision, resulting in misalignment of the welding points and affecting the assembly effect, but also is not convenient for workers to operate and has certain safety hazards. Therefore, there is an urgent need for a construction device for controlling the assembly precision of large-span special-shaped steel trusses to solve the above problems.

The adjusting assembly 2 is composed of a concave cavity 202, a driving motor 201, a bidirectional screw 203, a screw block 204, and a connecting frame 205. One end of the connecting frame 205 is fixed with a positioning assembly 3. The positioning assembly 3 is composed of a U-shaped support 301, a flipping motor 303, and a positioning plate 302.

[0023] The concave cavity 202 is formed on the positioning seat 1. The bidirectional screw 203 is rotatably installed in the concave cavity 202. The output shaft of the driving motor 201 is fixedly connected to one end of the bidirectional screw 203. The driving motor 201 provides power for the bidirectional screw 203 to make it rotate.

[0024] The screw block 204 is threadedly connected to the bidirectional screw 203. The specification of the screw block 204 matches the specification of the concave cavity 202. The connecting frame 205 is welded to one side wall of the screw block 204. During the rotation of the bidirectional screw 203, the screw block 204 moves under the action of the thread and the limit of the concave cavity 202.

[0025] The support 301 is welded to the top end of the connecting frame 205. The positioning plate 302 is rotatably installed between the supports 301. The flipping motor 303 is fixed to one side wall of the support 301 by bolts. The output shaft of the flipping motor 303 is fixedly connected to the positioning plate 302.

The battery pack 6 provides the required electric energy for the device, and the staff can remotely control the work of the device through the main controller 7.

[0029] Working principle of this device: During use, first install the positioning seat 1 on one side wall of the main truss. During the installation process, the marking arrow 5 can be used to position the positioning seat 1 according to the splicing point. Then, energize the electromagnet 4 to adsorb and fix the positioning seat 1 on one side wall of the main truss. Next, hoist the sub-truss so that it is near the splicing point. At this time, use the flipping motor 303 to change the positioning plate 302 from a horizontal state to a vertical state, and then hoist the sub-truss between the positioning plates 302. Then, drive the motor 201 to drive the bidirectional screw 203 to rotate, so that the screw block 204 drives the positioning plates 302 to move towards each other under the action of the thread, thereby clamping and positioning the sub-truss. Then, lower the height of the sub-truss so that it contacts the main truss and then weld it. This method not only has high positioning accuracy, but also is easy to operate, effectively improving the assembly efficiency of the steel truss.
