Description

Technical Field

[0001] The utility model relates to the technical field of steel box girder cutting, in particular to a transverse diaphragm cutting device for steel box girder manufacturing. Background Technique

[0002] The steel plate box girder is a commonly used structural form in engineering. To study the influence of the transverse diaphragm spacing on the distortion of simply supported steel box girders under concentrated loads, simply supported steel box girders with different numbers of transverse diaphragms are set up, and their distortion effects and rigid torsion effects under concentrated loads are compared. The variation curve of the maximum distortion effect with the number of transverse diaphragms is obtained. A concentrated load is applied at the top of the web of the box girder, and calculations are carried out using the method of load decomposition under four working conditions: distortion, rigid torsion, symmetric bending, and eccentric load.

[0003] After retrieval, a transverse diaphragm cutting device for steel box girder manufacturing disclosed in a Chinese patent with the publication number CN213052977U has the following technical key points: including a cutting mechanism and an adjusting mechanism. The cutting mechanism includes a connecting frame, a mounting plate, and a motor. The mounting plate is installed below the connecting frame, the motor is installed at the rear of the mounting plate, a cutting tool is installed at the front of the mounting plate, a protective cover is arranged outside the cutting tool, an air intake cover is arranged above the protective cover, a connecting pipe is installed on the air intake cover, a fan is installed at one end of the connecting pipe away from the air intake cover, and a dust filtering box is arranged on the side of the fan. The utility model has a simple structure, reasonable design, and low production cost. It can automatically cut the transverse diaphragm, greatly saving manpower. At the same time, it can collect the dust generated during cutting, effectively protecting the health of workers.

[0004] The above solution solves the problem that currently, a cutting machine is manually held for cutting, which is not only laborious but also generates a large amount of dust during cutting, endangering the health of workers. However, the above solution has poor stability, and the steel box girder is prone to shaking and vibration during cutting, resulting in a decrease in cutting accuracy.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

The threaded cylinder drives the corresponding sliding block to move, and the sliding block drives the sliding column to contact the steel plate. The rod supports the sliding column, thereby realizing that the device can clamp the steel plate through the pressing piece and limit the steel plate through the sliding column, improving the stability of the device during cutting and preventing the steel plate from shaking during cutting, which may lead to a decrease in cutting accuracy.

[0016] 2. The utility model realizes the synchronous rotation of the bidirectional threaded rods by setting components such as a second gear, a motor, a first gear, and a rack. The motor is placed and connected to the support rod. The motor drives the first gear to rotate. The first gear meshes with the rack to drive the rack to move.

[0031] When using the present utility model: The steel plate is transferred to the lower part of the cutting module 21 by the working roller 17. When pulling the connecting rod 12 to drive the pressing piece 8 to move, the sliding column 6 is driven to move inside the cavity 4. At this time, the spring 5 is stretched, and then the spring 5 resets to drive the sliding column 6 and the pressing piece 8 to clamp the steel plate. The motor 13 drives the first gear 14 to mesh with the rack 15, driving the rack 15 to move. The rack 15 meshes with the second gear 11 to drive the second gear 11 to rotate.
