Description

Technical Field

[0001] The utility model relates to the technical field of steel structure anti-corrosion tools, in particular to an assembled steel structure anti-corrosion treatment device. Background Technique

[0002] A steel structure is a structure composed of steel materials and is widely used in the construction field. Since the steel structure is exposed outdoors for a long time, it is prone to rust, so anti-corrosion treatment is required. Currently, the common anti-corrosion method is to coat an anti-corrosion layer on the surface of the steel structure.

[0003] After retrieving the patent document with the publication number CN218796784U, this device drives the support connecting rod and the steering block to rotate through a designed motor, so that the central turntable drives the rotating box to swing, and the spraying nozzle reciprocates around the axis of the rotating box, realizing the continuous up-and-down swing of the spraying nozzle.

[0004] In this patent document, after the steel structure is welded, there may be uncleaned welding slag on its surface. At the same time, in the face of complex weld conditions such as the bending and corner parts of the steel structure, if the slag removal tool cannot adjust the slag removal angle according to the weld environment, manual tools need to be used to process such welding slag, which affects the work efficiency. Moreover, some of the welding slag after brushing still remains on the surface of the steel structure and needs to be cleaned. Most of the current steel structure anti-corrosion tools can only perform spraying work, and the spraying, brushing of welding slag and cleaning of welding slag cannot be solved integrally, and there is room for improvement and optimization.

A guiding block that linearly slides along the sliding card slot 214 is provided in the middle of the locking tooth disc A205. By linearly sliding the locking tooth disc A205 along the card slot 214 of the turning frame shaft 212, the locking tooth disc A205 is engaged with the locking tooth disc B206.

[0029] In this embodiment: The slag suction assembly includes a slag suction box 203, which is fixedly connected to the lower end of the slag removal fixing frame 204 close to the flexible support column 211.

At this time, the locking tooth disc B 206 rotates to this position along with the turning frame 207. Push the locking tooth disc A 205 to slide linearly along the turning frame shaft 212 and engage with the locking tooth disc B 206. Rotate the hand-twisting sleeve 208 to make the hand-twisting sleeve 208 screw into the direction along the turning frame shaft 212 and top dead the locking tooth disc A 205, controlling the locking tooth disc B 206 not to move, and thus fixing the slag removal mechanism 2 at this position. Start the switch of the hand-held grip 3, and the vibration motor 202 in the groove of the wire cleaning brush 201 works, driving the wire cleaning brush 201 to vibrate, breaking and sweeping the welding slag on the surface of the steel structure. Compressed air is introduced into the vacuum generator 210 in the slag suction assembly to generate negative pressure in the slag suction box 203 and collect the welding slag.
