Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and particularly relates to an adjustable vertical assembly frame for assembling plane trusses. Background Art

[0002] Trusses are widely used in steel structures, mainly in industrial and civil building roofs (roof trusses, etc.), crane beams (i.e. crane trusses), stations and bridges. Steel trusses are commonly used as the main components of load-bearing structures. The most commonly used steel trusses are plane trusses, which are actually lattice beams under lateral loads.

[0003] The traditional assembly method of segmented trusses mainly adopts an integral portal frame for assembly, but this assembly method has the disadvantages of high material consumption, complicated frame assembly process, high site requirements, and inflexible frame layout, which reduces the efficiency of workers in assembling the trusses. At this time, an adjustable vertical assembly frame for assembling flat trusses is needed to improve the assembly efficiency of the trusses. Utility Model Content

Through the vertical columns, the device can reduce the requirements for the site and can splice two trusses at the same time, which solves the problem that the existing assembly method of segmented trusses mainly adopts an integral portal cradle for assembly. However, this assembly method has the disadvantages of large material consumption, complicated cradle assembly and processing process, high site requirements, and insufficient flexibility in cradle layout, which reduces the efficiency of workers in assembling trusses.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

By setting the column, the requirements for the site when assembling the trusses are reduced, and at the same time, workers can assemble two trusses together, thereby improving the assembly efficiency of the trusses.

[0007] Furthermore, the parts contained in the two square grooves are the same, the inner wall of the square groove is fixedly connected to a fixing rod, and the outer surface of the fixing rod is rotatably connected to a rotating block.

By setting the adjustment component, the device can assemble trusses of various heights, avoiding the need for workers to replace the tire frame when assembling different trusses, thereby reducing the workload of workers.

[0010] Furthermore, the left and right sides of the gear one are meshedly connected with gear two, and the two gear twos are fixedly connected with threaded rods. By setting the gear one, the motor can drive the two threaded rods to move at the same time.

[0011] Furthermore, a square groove one is opened on the left and right sides of the column, and the two square grooves are symmetrically arranged with the column as the center.

Several circular grooves 2 are opened inside the column, and the bolts are plugged into the circular grooves 2. Nuts are threadedly connected to the outer surfaces of the two bolts. By setting the fixing blocks, the partition steel pipe can fit more tightly to the surface of the column.

The top of the fall chain hook 15 is in contact with the outer surface of the truss 4. By setting a column, specifically by adjusting the position so that the fall chain hook 15 can hook the upper flange plate on the side of the truss, the electric fall chain 13 is opened to tighten the chain 14, so that the fall chain hook 15 can generate a pulling force on the truss 4 so that the truss 4 can lean on the column, reducing the requirements for the site when assembling the truss 4, and at the same time allowing workers to assemble two trusses 4 together, thereby improving the assembly efficiency of the truss.

[0034] A specific application of this embodiment is as follows: first, the number of tire frames is determined according to the number of truss segments. If the number of segments is n, n+1 tire frames need to be processed. The transport vehicle truss is hoisted onto the tire frame by a lifting machine. The position is adjusted so that the fall chain hook 15 can hook the upper flange plate on the side of the truss. The electric fall chain 13 is opened to tighten the chain 14. The model specification of the electric fall chain is CD5T-18m, so that the fall chain hook 15 can generate tension on the truss 4 so that the truss 4 can lean against the column, so that the truss 4 can avoid tipping over during assembly. When the truss 4 is assembled, the hook can be released, so that the truss 4 can be directly lifted after assembly without flanging the truss 4, which reduces the site requirements when assembling the truss 4. At the same time, it allows workers to assemble two trusses 4 together, thereby improving the assembly efficiency of the truss. When the device needs to assemble trusses 4 of different models, it is counterclockwise. Rotate the nuts to remove the eight nuts. After the nuts are removed, pull the eight bolts 32 out of the fixed block 31, turn on the motor 222 to drive the rotating shaft 223 to rotate, and the rotating shaft 223 will drive the gear 1 224 to rotate during the rotation of the rotating shaft 223. When the gear 1 224 rotates, it will drive the gear 2 225 on the left and right sides to rotate. When the gear 2 225 rotates, it will drive the threaded rod 226 to rotate in the inner wall of the square groove 1 opened on both sides of the column 2. When the threaded rod 226 rotates, it will drive the moving block 228 to move upward. When the moving block 228 moves upward, it will drive the separating steel pipe 227 to move upward. When the two separating steel pipes 227 move to the required position, turn off the motor to stop the two separating steel pipes 227 from moving, and insert the eight bolts 32 into the circular groove 1 opened in the fixed block 31 respectively. Fix the bolts 32 with nuts to improve the stability of the separating steel pipe 227.
