Description

Technical Field

[0001] The invention relates to the technical field of steel structure grid erection tools, in particular to an assembly system for steel structure grids. Background Art

[0002] Steel structure grid is a spatial structure formed by connecting multiple steel rods through nodes in a grid form. Its basic units include triangular grid, quadrilateral grid, hexagonal grid, circular grid, etc. It has the advantages of stability, high spatial rigidity, saving steel, reducing deadweight, good seismic resistance, good extensibility, and fast construction speed. When splicing steel structure grid, an assembly system is required, through which strips and blocks can be assembled directly in the air.

[0003] However, the existing assembly system has great defects during use. The existing assembly system needs to be used with the help of other lifting equipment, which is very inconvenient to use. At the same time, the height cannot be adjusted, and it cannot be assembled according to steel structure grids of different heights. The operating range is small. After the existing assembly system completes the assembly of a grid, it needs to be disassembled and the assembly system needs to be reinstalled at the next assembly grid location, which increases the time for disassembling, moving and reinstalling the assembly system, thereby affecting the use efficiency of the assembly system. The existing assembly system is not flexible enough in adjusting the components of the steel parts, so that the alignment between the steel parts is not accurate enough, which in turn affects the firmness of the assembled steel structure grid. The existing assembly system requires manual assistance to fix the steel parts, which requires the staff to perform high-altitude operations, resulting in poor safety in use.

The base frame 1 is horizontally arranged, the steel column 2 is vertically arranged, and the steel column 2 is movably matched on the top of the base frame 1. A lifting plate 3 is lifted and lowered on the steel column 2. The rotating column 4 is rotatably matched on the top of the lifting plate 3 through the rotating base 5. By moving the steel column 2 to cooperate with the rotating column 4, the position and angle of the extension arm 6 are adjusted to make the adsorption frame 7 07 The position of the adsorbed steel parts has a wider adjustable range and higher flexibility, so that the assembly system can adjust the position of the steel parts in more complex steel structures, so that the assembly system can assemble more types of steel structure grids, thereby increasing the range of the assembly system to erect steel structure grids. The extension arm 6 is horizontally arranged, and the extension arm 6 is lifted and matched on one side of the rotating column 4. By rotating the extension arm 6 and adjusting the height of the extension arm 6, the adsorption frame 707 can lift steel parts from a wider range around the lifting carrier 3, thereby making the lifting carrier The surrounding side of 3 can mount more frames with steel parts, thereby improving the endurance of the assembly system. The steel part hanging and rotating assembly 7 moves horizontally and cooperates with the bottom of the extension arm 6. The steel part fixing assembly 8 is fixedly installed on the top of the extension arm 6 away from the end of the rotating column 4. By setting the steel part fixing assembly 8 and using the screw machine 907 (model: XH-SCLSJ800) in the steel part fixing assembly 8 to tighten the erected steel parts, the structural strength of the steel structure grid assembled by the assembly system is higher. At the same time, by tightening with the screw machine 907, the steel structure grid assembled by the assembly system is easy to disassemble, reducing the trouble of disassembling the steel structure grid later. By using the steel part hanging and rotating assembly 7 to lay the steel parts, and by using the steel part fixing assembly 8 to fix the laid steel parts, the whole process does not require manual participation of personnel, nor does it require personnel to work at high altitude, avoiding danger to personnel, thereby greatly improving the safety of the use of the assembly system.

[0047] When in use, first, the assembly system is moved to the side of the building where the steel structure grid needs to be assembled, the base frame 1 is fixed on the ground or on the transport vehicle, and a frame with steel parts is fixed on one end of the lifting plate 3. The second motor 203 is used to drive the second screw rod 202 to rotate, and the lifting block 301 is driven up and down by rotating the second screw rod 202. The lifting plate 3 is adjusted to a height flush with the assembly position of the steel structure grid by moving the lifting block 301. The height of the lifting plate 3 is adjusted by using the second motor 203 to drive. On the one hand, the assembly system does not need to use other equipment to achieve high-altitude operations, thereby making the use of the assembly system more convenient. On the other hand, the assembly system can be used for steel structure grids of different heights. The assembly is performed so as to make the operation range of the assembly system wider. Then, a steel part is adsorbed from the frame by the vacuum suction cup 708 at the bottom of the adsorption frame 707, and the third screw rod 402 is driven by the third motor 403 to rotate. By rotating the third screw rod 402, the nut 603 is driven to move. The nut 603 drives the extension arm 6 to move up and down through the lifting side plate 601. The extension arm 6 is adjusted upward so that the height of the steel part adsorbed at the bottom of the adsorption frame 707 is higher than the assembly position of the steel structure grid. The rotating bottom plate 503 is driven to rotate by the fourth motor 502. The rotating bottom plate 503 drives the rotating column 4 to rotate. By rotating the rotating column 4, the extension arm 6 is rotated to the top of the steel structure grid to be assembled, and driven by the fifth motor 608. The pulley 606 is rotated, and the pulley 606 drives the transmission belt 607 for transmission. The transmission belt 607 drives the adsorption frame 707 to move horizontally through the shift plate 701.

By adjusting the extension arm 6 downward, the steel parts are assembled on the steel structure. The first motor 102 drives , driving the steel column 2 to move. On the one hand, after assembling one steel structure grid frame, the assembly system can continue to assemble the next steel structure grid frame by moving the position of the steel column 2, thereby making the assembly system more capable of continuous operation, reducing the time for disassembling, moving and reinstalling the assembly system, thereby making the use efficiency of the assembly system higher. At the same time, it also reduces the number of times the staff installs and disassembles the assembly system, thereby further improving the convenience of using the assembly system. On the other hand, the fourth motor 502 drives and drives the rotating column 4 to rotate. By moving the steel column 2 and cooperating with the rotating column 4, the position and angle of the extension arm 6 are adjusted, so that the position of the steel parts adsorbed by the adsorption frame 707 can be adjusted in a larger range and with higher flexibility.Thereby, the assembly system can adjust the position of steel parts in more complex steel structures, and the assembly system can assemble more types of steel structure grids, thereby increasing the scope of the assembly system for erecting steel structure grids. By using the fourth motor 502 to drive the rotating column 4 to rotate, and then rotating the extension arm 6, on the one hand, the working direction of the assembly system can be flexibly adjusted, so that when the assembly system fixes the base frame 1, there is no need to deliberately adjust the direction of the base frame 1, so that the installation and fixation of the assembly system is simpler and more convenient, thereby further improving the convenience of use of the assembly system. At the same time, the assembly system can be used in a smaller venue, thereby increasing the scope of application of the assembly system to the venue of use. On the other hand, the third motor 403 drives to adjust the extension arm 6. The height of the extension arm 6 is coordinated by rotating the extension arm 6 and adjusting the height of the extension arm 6, so that the adsorption frame 707 can lift steel parts from a larger range around the lifting platform 3, and then the lifting platform 3 can be mounted with more frames containing steel parts around the lifting platform 3, thereby improving the endurance of the assembly system. By using the fifth motor 608 to drive, the position of the adsorption frame 707 is adjusted, and the sixth motor 705 is driven to adjust the angle of the adsorption frame 707. By adjusting the position and angle of the adsorption frame 707, the assembly system can more accurately position the steel parts, and then the steel parts laid by the assembly system can be more flush, thereby improving the accuracy of the steel structure grid erected by the assembly system, and further, making the steel structure grid erected by the assembly system more in line with standards and more Safe and firm, finally, the seventh motor 803 drives the rotating frame 802 to rotate, the eighth motor 805 drives the first joint 804 to rotate, the ninth motor 807 drives the second joint 806 to rotate, and the tenth motor 809 drives the third joint 808 to rotate.

By setting up a steel fixing component 8 and using the screw machine 907 in the steel fixing component 8 to tighten the erected steel parts, the structural strength of the steel structure grid assembled by the assembly system is higher. At the same time, the screw machine 907 is used for tightening, so that the steel structure grid assembled by the assembly system is easy to disassemble, reducing the trouble of disassembling the steel structure grid at a later time. The steel parts are laid by using the steel hanging component 7 and the laid steel parts are fixed by the steel fixing component 8. The whole process does not require manual participation of personnel, nor does it require personnel to work at high altitudes, avoiding danger to personnel, thereby greatly improving the safety of the use of the assembly system. At the same time,It replaces manual work more comprehensively, greatly reducing the labor intensity of the staff.
