Description

Technical Field

[0001] The present application relates to the technical field of steel trusses, and in particular to a horizontal assembly and turning device for steel truss arches. Background Art

[0002] A steel truss is a truss made of steel. It's often used as the primary load-bearing component in industrial and civil building roof structures, crane beams, bridges, and hydraulic gates. The steel truss arch is a bridge structure that combines the characteristics of both arches and trusses, resulting in unique load-bearing properties and a wide range of applications.

[0003] If the steel truss arch is assembled vertically, the workers will work at a height as the production progresses, which will cause safety hazards. Therefore, horizontal assembly can be safer, but horizontal assembly requires a turning device to flip the steel truss arch 90 degrees to stand upright for easy installation. Summary of the Invention

[0004] The purpose of this application is to provide a horizontal turning device for steel truss arches in order to solve the above problems. The device adopts a rotating support structure, which can keep the steel truss arch in the rotated upright position unchanged, making it easy to install later. At the same time, it can adapt to steel truss arches of different sizes by adjusting the spacing between the supports.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] A horizontal turning device for a steel truss arch includes a base frame, a winch, a support column, a sliding column, a U-shaped connector, and a through-hole. A linear drive assembly for adjusting the height of the winch is provided on one side of the base frame, and a support column penetrating the front and rear parts of the base frame is provided on the other side of the base frame, and the support column and the base frame are slidably engaged, and a sliding column is provided on the inner side of the support column and is slidably engaged with the inner wall of the support column. The ends of the support column and the sliding column are both provided with a rotatable support arm assembly, and a detachable U-shaped connector is provided on the support arm assembly, and the U-shaped connector is provided with a through-hole through which a fastener can pass.

[0007] Furthermore, a first fastening bolt for fastening the support column is threadedly provided on the base frame, and a second fastening bolt for fastening the sliding column is threadedly provided on the support column.

[0008] Furthermore, the linear drive assembly includes a shell, a sprocket, a rotating shaft, a chain, a motor, a slider, and a slide rail. The shell is arranged vertically and the bottom is fixedly connected to the base frame. Two sprockets are provided in the base frame, and chains are wrapped around the outside of the two sprockets. Both sprockets are provided with a rotating shaft for supporting their rotation. The rotating shaft is rotationally connected to the shell. The outer wall of the shell is fixedly connected to a motor for driving one of the rotating shafts to rotate. The slider is fixedly connected to the chain. The inner wall of the shell is fixedly provided with a slide rail arranged in a vertical direction. The slider has a slide groove that can slide with the slide rail, and the slider is fixedly connected to the winch to support the lifting of the winch.

[0009] Furthermore, the support arm assembly includes a support shaft and a support plate. The support shaft is rotatably connected to the support column and the sliding column. One end of the support plate is fixedly connected to the support shaft. A displacement groove is opened along the length direction of the support plate.

A linear drive assembly for adjusting the height of the winch 10 is provided on one side of the base frame 1, and a support column 11 that passes through the front and rear parts of the base frame 1 is provided on the other side of the base frame 1, and the support column 11 slides with the base frame 1, and a sliding column 12 that slides with the inner wall of the support column 11 is provided on the inner side of the support column 11, and a rotatable support arm assembly is provided at the ends of the support column 11 and the sliding column 12, and a detachable U-shaped connector 17 is provided on the support arm assembly, and a through-hole 18 is provided on the U-shaped connector 17 for a fastener to pass through.

[0021] Specifically, the linear drive assembly adjusts the height of the winch 10 to adapt to the angle and height of the steel truss arch flipping, so that the flipping process is smoother. The support column 11 can translate on the base frame 1, and then the sliding column 12 can translate inside the support column 11, thereby adjusting the distance between the support column 11 and the arm assembly at the end of the sliding column 12 to adapt to the size of the steel truss arch. The detachable U-shaped connector 17 facilitates the adjustment of the orientation and then facilitates fixed connection with the steel truss arch.

[0022] Furthermore, a first fastening bolt 13 for fastening the support column 11 is screwed onto the base frame 1 , and a second fastening bolt 14 for fastening the sliding column 12 is screwed onto the support column 11 .

[0023] Specifically, the support column 11 is fastened by screwing the first fastening bolt 13 , and the sliding column 12 is fastened by screwing the second fastening bolt 14 , so that the support column 11 and the sliding column 12 maintain unchanged positions during the flipping process.

[0024] Furthermore, the linear drive assembly includes a shell 2, a sprocket 4, a rotating shaft 5, a chain 6, a motor 7, a slider 8, and a slide rail 9. The shell 2 is arranged vertically and the bottom is fixedly connected to the base frame 1. Two sprockets 4 are provided in the base frame 1, and the two sprockets 4 are surrounded by a chain 6 on the outside. Both sprockets 4 are provided with a rotating shaft 5 for supporting their rotation. The rotating shaft 5 is rotationally connected to the shell 2. The outer wall of the shell 2 is fixedly connected to a motor 7 for driving one of the rotating shafts 5 to rotate. The slider 8 is fixedly connected to the chain 6. The inner wall of the shell 2 is fixedly provided with a slide rail 9 arranged in a vertical direction. The slider 8 has a slide groove that can slide with the slide rail 9, and the slider 8 is fixedly connected to the winch 10 to support the lifting and lowering of the winch 10.

[0025] Specifically, the motor 7 is started to drive the chain 6 to rotate so that one of the rotating shafts 5 rotates, and then the sprocket 4 rotates synchronously, so that the chain 6 conveying the slider 8 around the sprocket 4 is lifted and lowered, and then the winch 10 is lifted and lowered.

[0026] Furthermore, the support arm assembly includes a support shaft 15 and a support plate 16. The support shaft 15 is rotatably connected to the support column 11 and the sliding column 12. One end of the support plate 16 is fixedly connected to the support shaft 15. A displacement groove 19 is opened along the length direction of the support plate 16. The fastening bolt 20 passes through the displacement groove 19 for fastening the U-shaped connector 17.

[0027] Specifically, the support shaft 15 can rotate on the support column 11 and the sliding column 12 to facilitate adjustment of the angle so that the U-shaped connector 17 is connected to the steel truss arch.

[0028] Furthermore, each arm assembly is provided with two U-shaped connectors 17 to be firmly connected to the steel truss arch.

[0029] Furthermore, a diagonal brace 3 is fixedly provided between the outer wall of the shell 2 and the base frame 1 to strengthen and support the shell 2 .

[0030] In the above structure, the U-shaped connector 17 is fixed to the horizontally assembled steel truss by fasteners passing through the through-holes 18. At this time, the support plate 16 is in a vertical state. Then the cable on the winch 10 is connected to the middle part of the steel truss arch. The winch 10 is started to pull the steel truss arch so that it rotates around the support shaft 15. At the same time, the support shaft 15 supports the support plate 16 to rotate. The sprocket 4 is driven to rotate by the starting motor 7, and then the chain 6 is rotated to adjust the height of the slider 8 so that the winch 10 can adapt to the flipping angle of the steel truss arch. When the steel truss arch is flipped 90 degrees, it can be installed and fixed.
