Description

Technical Field

[0001] The invention relates to the field of deck maintenance devices, and more particularly to a deck integrated stepping working vehicle for a marine electromagnetic paint removal device. Background Art

[0002] Among the current daily maintenance of various types of ships, the maintenance of ship decks is the most difficult. Since the deck coating is a key working area, the coatings applied are all thick and heavy anti-corrosion coatings. When wear occurs, it is difficult to maintain local areas. The current deck maintenance is done manually with a manual scraper, which has low work efficiency, poor maintenance accuracy, and is difficult to meet the daily maintenance needs of ships. At the same time, manual scraping of the coating seriously damages the deck steel, reducing the corrosion resistance and mechanical strength of the steel frame.

[0003] The marine electromagnetic paint removal device disclosed in the patent with patent number 2011100834349 and patent name "Device for removing coatings on the surface of steel" requires a handheld induction heating front end to perform construction operations each time it is used. This working method has low work efficiency and poor adjustment accuracy. Summary of the invention

[0012] Furthermore, a water spray pipe of the spray device is arranged on one side of the frame.

[0013] Furthermore, the bottom of the water spray pipe is close to the ground and is bent at 90°.

[0014] Furthermore, the upper portion of the water spray pipe is fixed to the vehicle frame via a water valve bracket, and the lower portion of the water spray pipe is connected to the vehicle frame via a connecting plate.

[0015] The beneficial effects of the present invention are:

[0016] A height adjustment device is provided to adjust the height of the vehicle to meet the requirements of coating thickness of different ship decks;

[0017] The clamp and the flat iron form a fixing device so that the marine electromagnetic paint removal device is stably fixed on the stepping work vehicle;

[0018] The flat iron is set in a V shape, and the V shape is used to better support the weight of the device to be fixed and achieve a stable mechanical balance;

[0019] The hexagonal nut is screwed to determine the position of the hexagonal nut at the connecting end of the support frame, so as to adjust the length of the connecting end of the support frame passing through the connecting frame, thereby adjusting the height of the connecting frame relative to the deck. Since the induction heating front end is arranged on the connecting frame, the height of the working head of the induction heating front end relative to the deck can be achieved;

[0020] The present invention adopts a unique special tool form to carry out ship deck maintenance, can adjust the working height according to the different thicknesses of coatings on the ship deck, and can perform micro-water flow spraying for cooling in special areas.

[0039] Working process: When in use, fix the induction heating head on the clamp 3 and the flat iron 4, adjust the hexagonal nut 9-1 according to work requirements to adjust the height of the directional wheel 2, thereby adjusting the height of the connecting frame 6 relative to the deck, so that the working head 25 of the induction heating head can be close to / far away from the deck. During work, micro-water spraying and cooling can be performed in special areas. During movement, the induction heating head is installed on the patented stepping work vehicle, which avoids the tedious manual hand-held operation and improves the accuracy. At the same time, there is no need to pull the main unit of the marine electromagnetic paint removal device to move around all the time. The switch 23 can be used to remotely turn on / off the induction heating head.
