Description

Technical Field

Beneficial effects: This utility model employs an internal support frame. When performing rust-proofing spray painting on cable trays, the cable tray can be placed in the spray booth, the mounting holes of the cable tray aligned with the internal support frame, and the cable tray moved until the internal support frame is inserted into the mounting holes. A hydraulic cylinder is activated to push a conical head downwards, causing the internal support frame to open and clamp the mounting holes of the cable tray, thus fixing the cable tray. This facilitates rust-proofing spray painting for workers. The internal support frame, inserted into the mounting holes of the cable tray for fixation, does not obstruct the surface of the cable tray, further reducing the obstructed area and improving the efficiency of rust-proofing spray painting. The internal support frame, after opening, clamps the mounting holes with high stability. The opening and closing of the internal support frame is completed by the extension and retraction of a cylinder, greatly facilitating installation and handling by workers and further improving ease of use.

[0036] It should be noted that: similar signs and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0037] As Figure 1 - Figure 3As shown, the bridge anti-rust treatment device comprises a base 1, which can be a framework composed of square tubes or aluminum profiles as shown, or a support platform that can enclose an internal space; two moving mechanisms 2 are arranged on the top of the base 1 on both sides, and one or two second roller supports are arranged between the two moving mechanisms 2, and the moving mechanisms 2 are used to drive the bridge to move towards the other moving mechanism 2 through the second roller support;

[0038] Between the two moving mechanisms 2, specifically above the second roller support, a support 6 is fixed, the support 6 is connected with a linkage mechanism 5, and the linkage mechanism 5 is respectively connected with a surface treatment mechanism 3 and a coating mechanism 4, the linkage mechanism 5 is used to drive the surface treatment mechanism 3 and the coating mechanism 4 to reciprocate along the conveying direction of the moving mechanism 2 to directly and indirectly contact with the bridge, with the direct contact of the surface treatment mechanism 3 with the bridge, the rust, bumps or dust on the surface of the bridge is removed; with the indirect contact of the coating mechanism 4 with the bridge, the anti-rust coating is coated on the surface of the bridge;

[0039] It should be noted that a cleaning plate (not shown in the figure) is also arranged on the support 6, which is in contact with the surface of the bridge and can clean the rust, bumps or dust removed from the surface of the bridge by the surface treatment mechanism 3 from the surface of the bridge, so that the rust, bumps or dust is preferably arranged around the bridge, and the anti-rust coating is not contaminated and attached to the clean surface of the bridge by cleaning the rust, bumps or dust from the surface of the bridge.

[0040] Further, as shown in Figure 2 The moving mechanism 2 comprises a first roller support 21, a conveying member and a lifting structure 22, the first roller support 21 combines with the second roller support to support the partial length of the whole bridge, and can move the bridge on the first roller support 21 and the second roller support, specifically, the roller support is composed of a body and a plurality of non-power transmission connected rollers rotatingly connected to the body in the conveying direction, and the plurality of rollers are arranged to form a surface for supporting the bridge, and the rollers can rotate with the movement of the bridge to achieve conveying of the bridge;

[0043] As shown in Figure 4 and referring to Figure 3 and Figure 1 , the linkage mechanism 5 not only drives the surface treatment mechanism 3 to treat the surface of the bridge forward and backward, but also drives the coating mechanism 4 forward and backward, thereby simulating the manual treatment action of the surface of the bridge and the action of manually uniformly coating the coating liquid on the bridge with a certain thickness, and combining the cleaning of the surface of the bridge by the surface treatment mechanism 3 before spraying, thereby improving the effect of the coating adhering to the bridge and improving the coating quality.

[0049] When the rust on the surface of the bridge is polished, the first cleaning plate 32 and the second cleaning plate 33 are both pasted with sandpaper on one side relative to the channel 31. The sandpaper is used to polish and remove the rust on the surface of the bridge by contacting the bridge. When the sandpaper is consumed, the first cleaning plate 32 and the second cleaning plate 33 can be removed and replaced. With the movement of the bridge in the channel 31, the inner and outer sides of the bridge can be cleaned by the friction contact of the first cleaning plate 32 and the second cleaning plate 33.
