Description

Technical Field

[0001] The invention relates to the field of metal steel processing, and in particular to a steel structure processing device and a use method thereof. Background Art

[0002] The steel structure includes steel pipe segments, also known as special lining ring segments, which are mainly used in special reinforcement sections in shield construction and special segments in communication channels between tunnels. The steel pipe segments are ring-shaped, and several steel pipe segments are combined together to form a complete ring-shaped pipeline. In the process of processing the steel pipe segments, it is necessary to grind their edges so that they can be better connected with other steel pipe segments. When grinding the steel pipe segments, it is necessary to use a fixing tool to clamp and fix the steel pipe segments. The existing steel pipe segment fixing tool uses two sets of clamping plates to clamp the two ends of the steel pipe segment when clamping and fixing the steel pipe segment, but this clamping will clamp the steel pipe segment. The edge of the steel pipe is partially covered, so that the grinding mechanism cannot fully grind the edge of the steel pipe piece. In addition, the existing steel pipe piece fixing tooling also uses a clamping plate to clamp the positive and negative curved surfaces of the steel pipe piece, so that the edge of the steel pipe piece can be fully exposed, which is convenient for the grinding mechanism to fully grind the steel pipe piece. However, since the clamping surface is a curved surface, the clamping plate needs to be a curved surface, but the sizes of steel pipe pieces are different. When processing steel pipe pieces of different sizes, different clamping plates are required for clamping. In order to solve this problem, the prior art uses an electromagnet. The iron plate is attracted to move toward the direction of the electromagnet, and the clamping block The first connecting rod and the second connecting rod are no longer clamped, and then the steel pipe segment body applies pressure to the second abutment plate, causing the second abutment plate to descend, the first spring is compressed, the second connecting rod descends, and then the first electric telescopic rod is started, the telescopic end of the first electric telescopic rod is stretched, pushing the operating panel and the first abutment plate to descend, the first abutment plate contacts the steel pipe segment body, and the steel pipe segment body pushes the first abutment plate, causing the first connecting rod to rise. When all the first abutment plates contact the steel pipe segment body, the staff turns off the electromagnet, and the iron plate and the clamp are reset under the action of the second spring force, and the clamp re-clamps the first connecting rod and the second connecting rod. At this time, the steel pipe segment body is fixed in the first Between the first abutment plate and the second abutment plate, steel pipe segments with different curvatures can be clamped; however, the weight of the steel pipe segment is heavy, and the elastic force of the spring is used to cooperate with the clamping, which has a poor effect, and the elastic properties of the spring inevitably cause the spring to shake when the steel pipe segment is processed, which will lead to unstable clamping of the steel pipe segment; when the grinding mechanism grinds the edge of the steel pipe segment, an industrial vacuum cleaner is usually used to absorb the debris generated by the grinding, but it is inevitable that a small amount of debris will fall on the surface of the workbench of the fixed tooling. After the grinding work is completed, it needs to be cleaned. For this reason, we propose a steel structure processing device and a method of use. Summary of the invention

[0017] 1. The present invention is provided with an upper clamping assembly and a lower clamping assembly with the same structure. Through the mutual cooperation of the upper clamping assembly and the lower clamping assembly, steel pipe segments of different sizes can be clamped at multiple clamping points according to the clamping needs, and the elasticity of the spring is not used to clamp the steel pipe segments of different sizes during clamping, so the clamping is more stable; before clamping, according to the size of the steel pipe segment, the fixing bolt is rotated to disengage the fixing bolt from the positioning plate, and then the position of the screw is adjusted, and then the position of the clamping strip is adjusted.

[0018] 2. When the present invention is in use, the electric push rod 1 drives the upper clamping assembly to move downward to clamp the steel pipe sheet, and at the same time drives the piston to move downward along the inner cavity of pipe 1. When the piston moves downward, the air in pipe 1 is discharged into pipe 2, and the air in pipe 2 is discharged through the exhaust pipe and finally discharged from the exhaust hood. The air discharged from the exhaust hood is blown to the filter screen, which can blow the debris adhered to the surface of the filter screen downward and pass through the discharge port into the receiving hopper; when the processing work is completed and the steel pipe sheet needs to be removed, the electric push rod 1 drives the upper clamping assembly to move upward and reset, and at this time drives the piston to move upward along the inner cavity of pipe 1. The upward movement of the piston along the inner cavity of pipe 1 will cause the suction pipe to draw air into the inner cavity of pipe 1. When the dust suction pipe draws air, it drives the debris remaining on the workbench to move, thereby ensuring that the debris remaining on the workbench can fall into the receiving hopper through the discharge port and the through hole.

[0038] The workbench 6 is provided with a discharge port 37 near the dust cover 12, and the workbench 6 is provided with multiple groups of through holes 38 near the discharge port 37; the discharge port 37 and the through holes 38 are provided so that the debris remaining on the workbench 6 can fall into the receiving hopper 39 through the discharge port 37 and the through holes 38.

[0040] Working principle of the present invention: when in use, according to the size of the steel pipe segment, the fixing bolt 205 is rotated so that the fixing bolt 205 is separated from the positioning plate 201, and then the position of the screw rod 202 is adjusted, and then the position of the clamping strip 203 is adjusted. After the position is adjusted, the fixing bolt 205 is rotated again so that the fixing bolt 205 is threadedly connected to the screw rod 202 and the positioning plate 201 again, so that the structure of the clamping strip 203 is stable, and then the multiple groups of clamping strips 203 on the upper clamping assembly 2 meet the clamping needs of different curved surfaces due to different sizes of steel pipe segments. Because the upper clamping assembly 2 has the same structure as the lower clamping assembly 8, the adjustment of the lower clamping assembly 8 is the same as the adjustment principle of the upper clamping assembly 2, so it will not be described in detail here;

[0041] A method for using a steel structure processing device includes using the steel structure processing device to process a steel structure.

[0042] When in use, the steel pipe piece is placed on the multiple groups of anti-skid strips 204 of the upper clamping assembly 2 through the dedicated equipment for the steel pipe piece, and then the two groups of electric push rods 14 are started to drive the lifting plate 3 to move downward, and the downward movement of the lifting plate 3 will drive the upper clamping assembly 2 to move downward until the anti-skid strips 204 in the upper clamping assembly 2 are tightly attached to the outer side of the steel pipe piece, and then through the multiple groups of clamping strips 203 in the upper clamping assembly 2 and the multiple groups of clamping strips in the lower clamping assembly 8, multiple positions of the steel pipe piece can be clamped at the same time, so that the steel pipe piece can be stably clamped;

[0043] It should be noted that the grinding mechanism for the steel pipe segment needs to be installed on the dust cover 12 or installed at the position where the through hole 38 is opened on the workbench 6, so that during the grinding process, the debris that is not absorbed by the industrial vacuum cleaner falls on the position of the workbench 6 where the through hole 38 is opened, or directly falls into the receiving hopper 39 through the discharge port 37 and the through hole 38;

[0044] When the grinding mechanism grinds the edge of the steel pipe piece, it is necessary to grind different edges of the steel pipe piece. At this time, the reducer 26 can be started to drive the rotating shaft 27 to rotate. The rotating shaft 27 rotates and under the transmission action of the two sets of sprockets 29 and the chain 30, it will drive the rotating column 44 to rotate. The rotation of the rotating column 44 will drive the rotating member 1 to rotate. The rotating shaft 27 rotates and under the transmission action of the two sets of sprockets 31 and the chain 32, it will drive the rotating rod 7 to rotate, thereby making the rotating rod 7 and the rotating member 1 rotate in the same direction and at the same speed. The rotating rod 7 and the rotating member 1 rotate in the same direction and at the same speed, which will drive the upper clamping assembly 2 and the lower clamping assembly 8 to rotate at the same speed and in the same direction, thereby making the clamped steel pipe piece rotate stably.

[0045] When the grinding work is completed, it is necessary to start the two sets of electric push rods 4 to drive the lifting plate 3 to move up and reset, so that the upper clamping assembly 2 leaves the steel pipe piece, which is convenient for taking down the steel pipe piece; when the lifting plate 3 moves up, the lifting plate 3 moves up and the piston rod 9 moves up, and the piston rod 9 moves up and the piston 10 moves up along the inner cavity of the pipeline 11, and the piston 10 moves up along the inner cavity of the pipeline 11, which makes the suction pipe 13 draw air into the inner cavity of the pipeline 11, and when the dust suction pipe 13 draws air, it drives the remaining debris on the workbench 6 to move, thereby ensuring that the remaining debris on the workbench 6 can pass through the discharge port 3 7 and through hole 38 fall into the receiving hopper 39; and when the two groups of electric push rods 14 drive the upper clamping assembly 2 to move downward to clamp the steel pipe sheet, the downward movement of the lifting plate 3 will drive the piston rod 9 to move downward, and the downward movement of the piston rod 9 will drive the piston 10 to move downward along the inner cavity of the pipeline 11. When the piston 10 moves downward, the air in the pipeline 11 will be discharged into the pipeline 2 15, and the air in the pipeline 2 15 will be discharged through the exhaust pipe 16 and finally discharged from the exhaust hood 17. The air discharged from the exhaust hood 17 will blow toward the filter screen 14, and the debris adhered to the surface of the filter screen 14 can be blown down and fall into the receiving hopper 39 through the discharge port 37.

[0046] It should be noted that a one-way valve 18 is provided so that the air in the pipe 11 between the piston 10 and the one-way valve 18 cannot be discharged through the one-way valve 18; a one-way valve 2 19 is provided so that the air in the exhaust pipe 16 cannot enter the pipe 11 through the one-way valve 2 19.

[0047] It should be noted that when the present invention is used, an appropriate external power supply and controller are required. The external power supply provides power support for the operation of the electric push rod 1 4, the reducer 26 and the electric push rod 2 42, and the external controller can control the operation of the electric push rod 1 4, the reducer 26 and the electric push rod 2 42.

[0048] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
