Technical Field

[0001] The utility model relates to the field of steel structure maintenance, in particular to an anti-rust spraying structure for steel structure gaps. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates.

[0003] Since the steel structure will expand or contract with the increase or decrease of the environmental temperature, expansion joints are set at specific positions to accommodate the deformation between steel structures. And because the steel structure expansion joints are usually exposed to the environment and the coating is damaged due to friction, rust prevention treatment is carried out on its surface during subsequent maintenance. The existing conventional method for rust prevention treatment of steel structure expansion joints is usually for workers to brush anti-rust paint, but this method has problems such as uneven brushing, easy omission, and low work efficiency. Therefore, a new anti-rust spraying structure for steel structure gaps is needed to improve the effect and efficiency of rust prevention treatment. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an anti-rust spraying structure for steel structure gaps, aiming to solve the problems that the existing conventional method for rust prevention treatment of steel structure expansion joints is usually for workers to brush anti-rust paint, but this method has problems such as uneven brushing, easy omission, and low work efficiency.

[0005] To achieve the above object, an anti-rust spraying structure for steel structure gaps proposed by the utility model includes a steel structure expansion joint. A rectangular frame is arranged at the top of the steel structure expansion joint, and an adjusting member is bolted to the bottom of the rectangular frame, and the bottom of the adjusting member is magnetically attracted to the steel structure expansion joint. An installation frame is slidably connected inside the rectangular frame, and a spraying member is arranged at the bottom of the installation frame;

[0006] The spraying member includes a lead screw. The lead screw is rotatably connected inside the installation frame. A nut block is threadedly connected to the surface of the lead screw.

[0007] Preferably, a slot for cooperating with the lead screw is opened inside the installation frame, and one end of the lead screw is externally connected to a driving device.

[0008] Preferably, a convex block is annularly arranged at the top of the inner wall of the sector spraying pipe, and the surface of the convex block is in rotational contact with the inner wall of the spray pipe. A limiting groove for cooperating with the convex block is opened on the surface of the spray pipe.

[0009] Preferably, the surfaces of the two nozzles are threadedly connected with fixed sleeves, and the bottom of the inner wall of the fixed sleeve is threadedly connected with the surface of the sector spraying pipe.

[0010] Preferably, a step portion is provided on the inner wall of the fixed sleeve, and the step portion is threadedly connected with the nozzle and the sector spraying pipe respectively.

[0011] Preferably, sliding blocks are bolted to the front side and the rear side of the mounting frame, and one side of the sliding block close to the inner wall of the rectangular frame extends into the interior of the rectangular frame.

Since the threads on the surfaces of the two screw rods are arranged in opposite directions, the two screw rods can move relatively until the horizontal adjustment of the rectangular frame is completed. Then, the mounting frame is adjusted by moving the sliding block in the sliding groove, and the position of the mounting frame is locked by the threaded cooperation between the fixing knob and the sliding block until the fixing knob is in close contact with the rectangular frame.
