Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe rust removal, in particular to a steel structure rust removal device. Background Art

[0002] When constructing buildings, bridges, roads, etc., a large number of construction steel structures are used, which can shorten the construction period and reduce the complexity of the project. However, when the construction steel structure is stored, it is easy to produce oxidation reaction with oxygen and water vapor in the air, which will form rust on the surface. The construction steel structure needs to remove rust before processing and use to avoid the rust affecting the construction.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing steel structure rust removal device uses a wire brush as the tool for steel pipes and steel structures, and the wire brush tool is held manually, squeezing the wire brush to fit the outer wall of the steel pipe while applying reciprocating force to move the tool. This method has a burden for rust removal and is poor in practicality, and is in urgent need of improvement. Therefore, we propose a steel structure rust removal device. Utility Model Content

[0004] The utility model aims to provide a steel structure rust removal device, which solves the problems raised in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a steel structure rust removal device, comprising a support plate, a wire brush is installed on the inner side of the support plate, the wire brush is attached to the outer wall of the steel pipe, and limit plates are fixedly installed at the bottom of both ends of the support plate;

[0006] The bottoms of both sides of the support plate are fixedly mounted with handles, and anti-slip sleeves are fixedly mounted on the handles, and an arc groove is opened on the lower surface of the support plate;

[0007] An arc-shaped plate is positioned in the arc-shaped groove, inner rods are movably penetrated on both sides of the arc-shaped plate, and the inner rods are fixedly connected to the arc-shaped plate, and a spring is sleeved on the rear side of the inner rod;

[0008] A driving motor is fixedly installed at the middle of the upper surface of the support plate, a rotating rod is fixedly installed at the bottom of the transmission shaft of the driving motor, a cam is fixedly installed at the bottom end of the rotating rod, and the cam abuts against one side of the arc plate;

[0009] The lower surface of the arc plate is fixedly connected to the wire brush, and the wire brush is pressed against the outer wall of the steel pipe. It can be used in combination with components such as the wire brush, cam and spring. During the use of the steel structure rust removal device, the support plate position can be maintained by holding the handle, and then the driving motor drives the cam to rotate. The cam can drive the arc plate to move, and cooperate with the spring to drive the arc plate back to its position, so that the arc plate can swing back and forth. During this period, the rust on the surface of the steel pipe can be cleaned by the contacting wire brush. Compared with manual cleaning of rust stains, the burden of manual rust removal can be reduced.

[0010] As an optional scheme of the technical scheme of the present application, push rod motors are fixedly installed on both sides of the limit plate, and a top block is fixedly installed on the inner end of the transmission shaft of the push rod motor. A bead groove is opened in the top block, and a limit bead movably positioned in the bead groove can be used in combination with components such as the push rod motor and the limit bead. Whenever the support plate is placed on the pipeline, the support plate can be pressed down by applying force, and at the same time, the transmission shaft of the push rod motor drives the top block to move inward until the limit bead contacts the pipeline, so that the support plate can be limited to the upper side of the pipeline. During the operation of the device, the personnel only need to apply force to maintain the handle position without squeezing the support plate downward, thereby further reducing the manpower burden. Since the limit bead can be rotatably arranged, when the support plate is dragged by manpower, the limit bead rolls, which can reduce the movement resistance and the use effect is more ideal.

[0011] As an optional solution to the technical solution of the present application, an indicator sticker is glued to one side of the upper surface of the support plate close to the handle, and guiding text is printed on the indicator sticker. The operator can be informed of the corresponding usage through the indicator sticker and the guiding text, so that different personnel can quickly and correctly engage in the operation.

[0012] As an optional solution of the technical solution of the present application, a battery is fixedly installed on the side of the support plate facing away from the indicator sticker. The battery is electrically connected to the drive motor and the push rod motor through wires. The battery can provide electrical energy to avoid pulling excessively long wires and reduce the cost of power supply.

[0013] As an optional solution of the technical solution of the present application, the two ends of the spring are fixedly connected to the inner wall of the arc plate and the support plate respectively. The fixed connection at both ends of the spring can prevent the spring from slipping through the two ends during expansion and contraction, thereby avoiding frequent reinstallation of the spring assembly.
