Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to auxiliary installation equipment for multi-story steel structure buildings. Background Art

[0002] Multi-story steel structures refer to steel structural systems suitable for multi-story and high-rise buildings. The load-bearing structure is typically composed of beams, columns, trusses, and other components made of section steel and steel plates. The high strength of steel structural materials makes the structure relatively light, which helps reduce foundation loads and seismic effects. Structural components are often prefabricated in factories and assembled on-site through welding or bolting, resulting in fast construction and minimal seasonal impact. In multi-story steel structures, beams serve as horizontal load-bearing components, connected between steel columns to support floor slabs and other lateral loads. The installation of beams requires precise positioning and adjustment to ensure they can withstand the design loads and maintain structural stability.

[0003] When auxiliary installation of beams is performed, the beams are usually hoisted from the ground or storage area to a designated position by hoisting equipment, and then aligned with the columns for installation. However, when auxiliary installation of long beams is performed, the larger the span of the beam, the more likely it is to bend and deform under the action of its own weight and load, which can easily cause the installation holes of the beams and the columns to not correspond, and workers need to manually pull the beams and columns to fit together, which makes it difficult to quickly fit the beams and columns together. If the fitting force is not properly controlled, the beams and columns may collide, which can easily cause damage to the beams and columns. Therefore, an auxiliary installation device for multi-story steel structure buildings is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when assisting the installation of long beams, the larger the span of the beam, the more it will bend and deform under the action of its own weight and load, so that the installation holes of the beam and the column do not correspond, and it is difficult for the staff to manually pull the beam and the column to fit together, and if the fitting force is not controlled well, the beam and the column will collide, which can easily cause damage to the beam and the column. The invention proposes an auxiliary installation device for multi-story steel structure buildings.

After the beam is placed in the lifting plate 7, the first control unit controls the fixed plate 10 to move downward and fix the beam, and the second control unit controls the fixed plate 10 to move laterally to support the installation of the beam, so that the lifting plate and the fixed plate can move in coordination to form a Z-shaped fixed beam, thereby eliminating bending deformation of the long beam. A displacement component is provided on the lifting plate 7, which includes a third control unit and a fourth control unit, a resistance sensor 32 installed at the bottom of the lifting plate 7, a support seat 26 movably connected to the bottom of the lifting plate 7, and a locking plate 31 symmetrically slidably arranged on the upper part of the support seat 26. The third control unit controls the two locking plates 31 to move in opposite directions to fix the beam, and the fourth control unit controls the movement of the support seat 26 and drives the beam to move. When the beam is displaced to fit with the column, the resistance sensor 32 senses the resistance to the movement of the beam in real time. After the beam is fit with the column, the resistance sensor 32 senses the resistance to the movement of the beam, and the beam stops moving. The beam is displaced by the rotation support with the rotating wheel 11, so that the beam can be displaced between the lifting plate and the fixed plate until the beam is fit with the column. The rotation resistance of the fourth servo motor is monitored in real time by the resistance sensor to avoid damage caused by excessive fit.

A second support rod is slidingly set on the inner side of the first support rod, and the second support rod is threadedly connected to the first threaded rod. The end of the second support rod away from the first servo motor is fixedly connected to the lifting plate. The rotating device drives the beam on the lifting plate to rotate, adjusts the position of the beam, and drives the first threaded rod to rotate through the first servo motor, thereby driving the beam to move upward.

[0022] A sliding groove is provided on the inner side of the lifting plate, a movable plate is slidably provided on the inner side of the sliding groove, and the upper part of the movable plate is fixedly connected to the fixed plate to support the movement of the fixed plate.

[0023] The first control unit includes a second servo motor 12 installed on the side of the lifting plate 7, a second threaded rod 13 installed on the end of the output shaft of the second servo motor 12, a first slide rail 14 installed on the side of the lifting plate 7, a first sliding block 15 slidingly provided on the inner side of the first slide rail 14, the first sliding block 15 and the second threaded rod 13 are threadedly connected, a push plate 16 is installed on the side of the first sliding block 15 away from the second servo motor 12, and a second slide rail 17 is installed on the end of the push plate 16 away from the first sliding block 15.

If the crossbeam is long, the second servo motor 12 can be started. After the second servo motor 12 is started, it drives the second threaded rod 13 to rotate. The force generated when the second threaded rod 13 rotates can drive the first sliding block 15 to move along the first slide rail 14, thereby driving the second slide rail 17 to move through the pushing plate 16. After the second slide rail 17 moves, it can drive the fixed plate 10 to move through the first movable plate 20. The fixed plate 10 moves along the sliding groove 8 through the movable plate 9, so that the lifting plate 7 and the fixed plate 10 form a Z-shaped structure. At this time, the lateral support distance between the lifting plate 7 and the fixed plate 10 can be lengthened, and then the third servo motor 18 can be started. After the third servo motor 18 is started, it drives the third When the threaded rod 19 rotates, the force generated when the third threaded rod 19 rotates can drive the first movable plate 20 to move down along the second slide rail 17, and at the same time drive the fixed plate 10 to move down. When the fixed plate 10 moves down, it moves down along the sliding groove 8 through the movable plate 9 until the rotating wheels 11 in the lifting plate 7 and the fixed plate 10 clamp the crossbeam to prevent the long crossbeam from bending and deforming.

The first threaded rod 4 is driven to rotate by the first servo motor 3. The force generated when the first threaded rod 4 rotates drives the second support rod 6 to move up along the first support rod 5, and at the same time drives the crossbeam fixed between the lifting plate 7 and the fixed plate 10 to move up until the crossbeam moves to the installation position.

The second movable plate 24 is threadedly connected to the fourth threaded rod 22, and an extension plate 25 is installed on the side of the second movable plate 24 away from the fourth servo motor 21, and the support seat 26 is fixedly connected to the support seat 26 at one end away from the second movable plate 24.

[0030] The third control unit includes a fifth servo motor 29 installed on the side of the support seat 26, and a fifth threaded rod 30 is installed on the output end of the fifth servo motor 29. Second sliding grooves 27 are symmetrically opened on the upper part of the support seat 26, and second sliding blocks 28 are slidably set on the inner sides of the two second sliding grooves 27. The two second sliding blocks 28 are both threadedly connected to the fifth threaded rod 30, and a locking plate 31 is installed on one end of the second sliding block 28 extending to the outside of the second sliding groove 27, and the crossbeam is fixed by the opposite movement of the two locking plates.

[0031] In this embodiment, when the crossbeam is installed, it is necessary to ensure that the crossbeam and the column are in contact with each other. At this time, the fifth servo motor 29 can be started. After the fifth servo motor 29 is started, the fifth threaded rod 30 is driven to rotate. The force generated by the rotation of the fifth threaded rod 30 can drive the two second sliding blocks 28 to move toward each other along the second sliding groove 27, thereby driving the two locking plates 31 to move toward each other and fix the crossbeam. Then, the fourth servo motor 21 is started. After the fourth servo motor 21 is started, the fourth threaded rod 22 is driven to rotate. The force generated by the rotation of the fourth threaded rod 22 can drive the second movable plate 24 It moves along the third slide rail 23 and drives the extension plate 25 to move at the same time.

After the fourth threaded rod 22 rotates, it drives the crossbeam on the support seat 26 to move until the crossbeam is in contact with the column. After the resistance sensor 32 senses the rotation assistance generated by the fourth servo motor 21, it automatically stops the rotation of the output shaft of the fourth servo motor 21. The crossbeam is supported by the rotating wheel 11 for rotation, so it can be displaced in the horizontal plane.
