DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] The embodiment of the present application provides a steel structure anti-corrosion coating construction device and a method for using the same, thereby solving the problem that during the spraying process of existing technicians, since the steel structure columns need to be sprayed 360 degrees, the arm needs to be constantly rotated to adjust the angle, which makes it difficult to spray evenly during operation, resulting in uneven coating thickness. During operation, the operator needs to constantly lift the nozzle and pipe, which is time-consuming and labor-intensive, and the operation is risky and requires high-altitude work.

[0063] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] Embodiment 11:

[0065] The embodiment of the present invention discloses a steel structure anticorrosive coating construction device. Figure 1 To Attachment Fig. 9 As shown, it includes a carrier 11, a spray unit 2, a carrying platform 3, a lifting unit 4 and a reciprocating drive unit 5;

[0066] The carrier 11 facilitates the carrying and movement of the device;

[0067] The spray unit 2 is arranged on the carrier 11 and used for spraying work. The spray unit 2 includes a storage box 21 arranged on the carrier 1 and a pump group 22 arranged on the storage box 21. The pump group 22 is connected to a pipeline 23, and the pipeline 23 is connected to a spray head 24. The storage box 21 is used to store paint. The paint is transported to the pipeline 23 through the pump group 22, and is sprayed through the pipeline 23 and the spray head 24, so as to be sprayed on the steel structure column and realize the construction of anti-corrosion paint on the steel structure.

[0068] The support platform 3 is disposed above the carrier 1 and is used to provide support for the spray head 24;

[0069] The lifting unit 4 is disposed on the carrier 1 and is used to control the height of the carrying platform 3; the lifting unit 4 includes:

[0070] The limiting frame 41 is arranged on the carrier 1 and used to support the carrying platform 3;

[0071] The motor 42 is arranged on the limiting frame 41;

[0072] The screw rod 43 is disposed at the output end of the motor 42 and is threadedly connected to the support platform 3 .

[0073] The lifting unit 4 has a compact structure and stable operation, and is convenient for lifting and adjusting the carrying platform 3. When the height of the carrying platform 3 and the spray head 24 needs to be adjusted, it only needs to be driven by the motor 42. The motor 42 drives the screw rod 43 to rotate, and the screw rod 43 drives the carrying platform 3 to slide along the limit frame 41, thereby driving the spray head 24 to adjust the height, so that the spray head 24 is continuously lifted and sprayed along the steel structure column;

[0074] The reciprocating drive unit 5 is disposed on the carrier 3 and is used to drive the spray head 24 to reciprocate. The reciprocating drive unit 5 includes:

[0075] A track seat 51 is provided on the spray head 24;

[0076] The movable bar 52 is arranged inside the carrying platform 3 and passes through the track seat 51;

[0083] An eccentric shaft 544 is disposed on the rotating disk 543;

[0084] The connecting rod 545 has two ends rotatably connected to the eccentric shaft 544 and the movable bar 52 respectively.

[0085] The reciprocating drive unit 5 has a compact structure and does not require additional power. It can convert the driving force of the lifting unit 4 into the reciprocating deflection of the spray head 24. The working principle is as follows:

[0086] When the carrying platform 3 is being lifted or lowered, the carrying platform 3 drives the gear 542 to move. Since the gear 542 is meshed with the rack 541, and the rack 541 is fixed to the limiting frame 411, the rack 5411 drives the gear 542 to rotate, the gear 542 drives the rotating disk 543 to rotate, the rotating disk 543 drives the eccentric shaft 544 to rotate, the eccentric shaft 544 drives the connecting rod 545 to move, and the connecting rod 545 drives the movable bar 52 to reciprocate and deflect;

[0087] At the same time, the movable bar 52 drives the movable column 53 to move, the movable column 53 drives the track seat 511 to move, and the track seat 511 drives the spray head 24 to move, so as to realize the continuous deflection of the spray head 24;

[0088] Therefore, while the lifting unit 4 drives the spray head 24 to move upward, the lifting unit 4 will also drive the reciprocating drive unit 5 and drive the spray head 24 to deflect back and forth, so that the spray head 24 can quickly apply steel structure anti-corrosion paint to the entire steel structure column, while realizing 360-degree deflection spraying, and the spraying is uniform without dead angles, meeting the use requirements.

[0089] A reinforcing sleeve 32 is provided on the supporting platform 3 for limiting the movable bar 52. The reinforcing sleeve 32 is used to reinforce the movable bar 52 so that the force on the movable bar 52 is stable.

[0090] The track seat 511 is provided with a slide groove 5111, and the slide groove 51111 provides a limit for the movable bar 52 and the movable column 53. The movable bar 52 is provided with a positioning shaft 521. The positioning shaft 521 enables the movable bar 52 and the connecting rod 545 to be rotatably connected, and the connection is stable.

[0091] The second aspect of the present invention provides a method for using a steel structure anticorrosive coating construction device, the method comprising the following steps: step S1, selecting a suitable spray head 24 for loading according to the steel structure column on site, and installing it on a bearing platform 3;

[0092] Step S2, moving the vehicle 1 to the target position;

[0093] Step S3, using the spray head 24 to surround the steel structure column;

[0094] Step S4, starting the spraying operation through the spraying unit 2;

[0095] Step S5, using the lifting unit 4 to drive the support platform 3 and the spray head 24 to adjust the height;

[0096] Step S6, when the lifting unit 4 drives the carrying platform 3 and the spray head 24 to move, it also drives the reciprocating drive unit 5 to move, so that the spray head 24 reciprocates and rotates to ensure that the anti-corrosion coating is sprayed evenly;

[0097] Step S7, after the spraying is completed, the device is restored to the initial state and the construction preparation for the next position is carried out.
