Description

Technical Field

[0001] The utility model relates to the field of ship maintenance equipment, in particular to a dock pier rust removal vehicle. Background Art

[0002] During the process of ship maintenance, it is necessary to remove rust from the outer plate of the ship and remove the paint and rust on the working surface. Generally, high-pressure water rust removal of the ship's outer plate is adopted. Construction workers use a flat trolley with an adjustable vertical rod to operate in the reverse direction. They mainly have to overcome the gravity of the device itself and the downward acting force of the nozzle operation. Workers need to overcome a downward pressure of about 40KG on the handle. The operation intensity of workers is high, and it cannot meet the requirements of long-term construction. Moreover, the current rust removal and cleaning equipment for ship bottoms has problems such as poor environmental adaptability, low operation efficiency, insufficient overall stability, and low automation. Especially in the narrow area between two dock piers, in the past, the operation of using a hand-held high-pressure spray gun to work in the reverse direction for a long time had a high labor intensity, low operation efficiency, and poor completion quality.

[0023] The following further describes the present utility model with reference to the drawings: As shown in the figure, the dock pier rust removal vehicle includes a vehicle body 1, and further includes a support rod 2, which is provided on the vehicle body in a liftable manner; a link 3, one end of which is hinged to the vehicle body, and the other end is hinged to a platform 4, and a nozzle 41 is provided on the platform; a second link 5, one end of which is hinged to the vehicle body, the other end is hinged to the platform, and the middle end is connected to the support rod. The vehicle body is connected to the platform through two links to form a link transmission structure, wherein the hinge point D2 of the second link with the platform is lower than the hinge point D1 of the link with the platform, and the second link itself is connected to the support rod and can swing when the support rod is lifted and lowered, and reference can be made to Figure 5 It is a schematic diagram after lowering, and at this time the platform is still horizontal. The hinge point D3 of the second link with the vehicle body, the hinge point D4 of the link with the vehicle body, and the distance between D3 and D4 is equal to the distance between D1 and D2.

[0024] In this embodiment, as shown in the figure, the second link is a tubular structure, and part of the link is provided inside the second link. The overall structure is more compact and the use effect is better. When the second link swings, the link will also swing accordingly.
