Description

Technical Field

[0001] The utility model relates to the technical field of crane spraying, in particular to an anti-corrosion spraying cover of a crane with a protective effect. Background Art

[0002] Cranes are widely used in construction and other fields. Since most cranes work in open-air environments, their casings are easily eroded by the scorching sun, rain, etc., which reduces their service life. Therefore, their surfaces need to be treated with anti-corrosion to slow down natural erosion during operation and idleness, thereby extending their service life.

[0003] However, in the prior art, most of the traditional anti-corrosion spraying equipment is not equipped with a spraying protective cover, which causes the paint particles scattered during spraying to flow with the air and then be inhaled by the workers, affecting the health of the workers.

The center of the spray shaft 22 is through, and the exhaust pipes 28 are symmetrically arranged on both sides of the spray shaft 22, and the exhaust pipes 28 extend to the outside of the fixed block 23.

[0022] The collecting mechanism 21 includes a connecting hole plate 211, and the outer wall of the connecting hole plate 211 close to the fixed block 23 is fixedly connected with an outer cylinder 212 and an inner cylinder 213, the inner cylinder 213 is arranged inside the outer cylinder 212, and the outer wall of the inner cylinder 213 away from one end of the connecting hole plate 211 is fixedly connected with a barrier plate 214, and the outer wall of the outer cylinder 212 away from the connecting hole plate 211 is in contact with the outer wall of the filter sponge 26. The inner wall of the outer cylinder 212 does not contact the outer wall of the inner cylinder 213, the inner wall of the inner cylinder 213 is threadedly connected to the outer wall of the spray shaft 22, the outer wall of the support rod 25 is rotatably connected to the inner wall of the connecting hole plate 211, the inner wall at the center of the connecting hole plate 211 is slidably connected to the outer wall of the spray shaft 22, the outer wall of the filter sponge 26 away from the connecting hole plate 211 is in contact with the outer wall of the groove on the fixed block 23, the inner wall of the barrier sheet 214 is slidably connected to the outer wall of the inner cylinder 213, and the outer wall of the barrier sheet 214 away from the inner cylinder 213 is in contact with the outer wall of the fixed block 23.

[0023] Working principle:

[0024] When in use, first fix the bottom of the support 3 on the external bracket, then place the filter sponge 26 in the groove of the side wall of the fixed block 23, rotate the adjustment block 27 to drive the spray shaft 22 to rotate, and when the spray shaft 22 rotates, it drives the collecting mechanism 21 threadedly connected thereto to approach the fixed block 23, and continuously rotate the adjustment block 27 until the barrier plate 214 contacts the fixed block 23. At this time, the filter sponge 26 is located between the inner cylinder 213 and the groove of the fixed block 23, completing the installation of the filter sponge 26, and at the same time completing the sealing of the collecting mechanism 21 to prevent subsequent leakage of paint particles from polluting the device.

[0025] As the collecting mechanism 21 continues to approach the fixed block 23, the supporting rod 25 rotatably connected to the connecting hole plate 211 will push the connecting rod 24 connected thereto to rotate around the fixed block 23 in a direction away from the collecting mechanism 21. As the spraying shaft 22 continues to rotate and drives the collecting mechanism 21 to approach the fixed block 23, when the outer wall of the barrier plate 214 contacts the outer wall of the fixed block 23, the connecting rod 24 will be fixedly connected to its outer wall and the protective cloth cover 1 will be fully opened.

[0026] When spraying for a long time, first move the spray shaft 22 away from the side of the collecting mechanism 21 and connect the paint preparation machine to the outside, so that the liquid anti-corrosion paint is sprayed out from the nozzle near the side of the connecting hole plate 211 through the through hole in the middle of the spray shaft 22, and the crane is subjected to the anti-corrosion spraying task. During the spraying process, scattered paint particles will be generated, and the protective cloth cover 1 will block them at this time to prevent them from escaping to the rear of the protective cloth cover 1 and being inhaled by the staff. At the same time, the outside of the exhaust pipe 28 is connected to the vacuum pump, and the vacuum pump continuously draws air outward from the exhaust pipe 28. At this time, the paint particles scattered in the air will be sucked into the chamber of the collecting mechanism 21 from the through hole opened on the connecting hole plate 211 with the action of the vacuum pump, and when the paint particles reach the filter sponge 26 with the airflow, they will adhere to the filter sponge 26, completing the collection of the scattered paint particles and preventing the scattered paint particles from being inhaled by the staff, thereby playing a protective role.

[0027] After spraying is completed, turn off the external vacuum pump and paint preparation machine, and disconnect them from the spraying mechanism 2. The adjusting block 27 is rotated in the opposite direction to drive the spray shaft 22 to rotate, so that the collecting mechanism 21 continues to move along the thread on the spray shaft 22 in the direction away from the fixed block 23. In the process of the collecting mechanism 21 continuously moving away from the fixed block 23, the filter sponge 26 will be separated from the fixed block 23. At this time, the filter sponge 26 is removed, and the collected excess paint is cleaned uniformly. As the collecting mechanism 21 continues to move in the direction away from the fixed block 23, the support rod 25 rotatably connected to the connecting hole plate 211 will drive the connecting rod 24 to rotate around the fixed block 23 to the side close to the collecting mechanism 21. The continuous rotation of the connecting rod 24 will drive the protective cloth cover 1 fixedly connected to its outer wall to shrink, thereby realizing the shrinkage of the entire spray hood and saving storage space for storage when the device is idle.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
