Description

Technical Field

[0001] The invention relates to the technical field of deck galvanizing, in particular to an automatic deck galvanizing device. Background Art

[0002] The deck is a platform or layer on a ship or aircraft, usually located on the top of the hull or fuselage, used for walking, operating equipment or storing cargo. The decks on ships are usually divided into multiple layers, including the main deck, the upper deck, etc. The main deck is the most important layer, usually the main area for loading passengers and cargo. The ship deck is also equipped with various equipment, such as ship-borne cranes, ship-borne hanging baskets, anchoring equipment, etc. The deck is mainly supported by steel. The deck needs to be galvanized before installation to ensure that the deck will not rust and affect the strength of the deck. The galvanizing of the deck is usually carried out in a galvanizing pool, but the galvanizing pool in the prior art usually cannot automatically replenish the zinc liquid, and the excess zinc liquid will be wasted. The deck needs to be pickled, washed, cooled and other operations before and after galvanizing. The whole process needs to be carried out continuously to ensure the galvanizing effect of the deck.

[0004] Furthermore, the main device includes a pickling tank, a water washing tank and a cooling tank fixedly installed on the bottom plate. The pickling tank is provided with a plurality of nozzles for spraying acid, the water washing tank is provided with a plurality of nozzles for spraying water, the cooling tank is filled with cooling water, a sliding column spring is provided between the galvanizing tank and the bottom plate, the galvanizing tank is filled with high-temperature zinc liquid, and a circulation mechanism, a downward pressure mechanism and an intermittent mechanism are provided on the bottom plate.

[0005] Furthermore, the circulation mechanism includes a driving shaft rotatably mounted on the base plate, a driving wheel is fixedly mounted on the driving shaft, a driven wheel is rotatably mounted on the base plate, a transmission belt is wrapped around the driving wheel and the driven wheel, a turntable ratchet is fixedly mounted on the driving shaft, and a number of lifting mechanisms are arranged on the transmission belt.

[0006] Furthermore, the lifting mechanism includes a connecting plate fixedly mounted on the transmission belt, an upper sliding column is slidably mounted on the connecting plate, a descending plate is fixedly mounted on the upper sliding column, a plurality of hooks are arranged below the descending plate, a spring plate is fixedly mounted on the upper sliding column, and an upper spring is arranged between the spring plate and the connecting plate.

[0007] Furthermore, the pressing mechanism comprises an outer sleeve fixedly mounted on the bottom plate, a pressing frame is slidably mounted inside the outer sleeve, an inner spring is arranged between the pressing frame and the bottom plate, and a small trapezoidal block is fixedly mounted on the pressing frame.

[0008] Furthermore, the intermittent mechanism includes an electric cylinder fixedly mounted on the base plate, a push rack fixedly mounted on the top of the electric cylinder, the push rack and the base plate being slidably mounted, a ratchet bar being slidably mounted on the push rack, a ratchet spring being arranged between the ratchet bar and the push rack, a large trapezoidal block fixedly mounted on the push rack, an external gear and a small trapezoidal block being slidably mounted, and the ratchet bar being meshed with the turntable ratchet wheel.

[0009] The deck to be galvanized is hung on the hook, and the electric cylinder extends, driving the push frame to slide along the bottom plate, thereby driving the ratchet bar forward, and the ratchet bar drives the turntable ratchet to rotate, thereby driving the driving shaft and the driving turntable to rotate, thereby driving the connecting plate forward through the transmission belt, and driving the connecting plate forward one station each time. When the ratchet bar is disengaged from the turntable ratchet, the connecting plate just moves forward one station. There are five stations in total for the connecting plate, namely the pickling station in the pickling tank, the water washing station in the water washing tank, the galvanizing station in the galvanizing tank, the static station on the lubricating plate and the cooling station in the cooling tank.

[0010] When the turntable ratchet is disengaged from the ratchet bar, the large trapezoidal block begins to contact the small trapezoidal block. As the electric cylinder continues to extend, it drives the large trapezoidal block forward, pushing the small trapezoidal block and the lower pressure frame down, the inner spring is compressed, and the lower pressure frame descends to press down the descending plate and hook above the pickling tank, water washing tank, galvanizing tank and cooling tank. The upper spring is compressed, and the hook above the pickling tank brings the deck into the pickling tank, and the nozzle in the pickling tank sprays acid to pickle the deck. The hook above the water washing tank brings the deck into the water washing tank, and the nozzle in the water washing tank sprays high-pressure water to wash the deck. The hook above the galvanizing tank brings the deck into the zinc liquid in the galvanizing tank for galvanizing. The hook above the cooling tank brings the deck into the cooling water in the cooling tank to cool the galvanized deck. The hook and deck staying above the synovial plate will not be pressed down, the deck is left stationary above the synovial plate, and excess zinc liquid falls onto the synovial plate.

[0011] After the electric cylinder extends to the farthest, it begins to retract. The lower pressure frame resets under the rebound of the inner spring, and the descending plate and the hook reset under the rebound of the upper spring, driving the deck to rise. When the electric cylinder retracts, the ratchet bar will not drive the turntable ratchet to rotate, and the ratchet spring will be compressed. Finally, the electric cylinder returns to the initial position and starts the next extension. The speed of the electric cylinder is slow, so that each station has enough dwell time. The electric cylinder continuously reciprocates and retracts. Each time the electric cylinder retracts and retracts, it drives the connecting plate to move forward one station, and the lower pressure frame presses down once.

[0013] Furthermore, the feeding mechanism includes an inner sliding column slidably installed in the outer sliding column, an inner sliding spring is arranged between the inner sliding column and the outer sliding column, an inner sliding sheet is fixedly installed on the inner sliding column, a top column is fixedly installed on the inner sliding sheet, the top column is in contact with the galvanizing pool, a vertical pole is fixedly installed on the inner sliding sheet, a vertical ratchet bar is slidably installed on the vertical pole, a vertical tooth spring is arranged between the vertical ratchet bar and the vertical pole, and the vertical ratchet bar is meshed with a transmission ratchet.

[0014] The galvanizing pool is filled with zinc liquid. When the zinc liquid is sufficient, the sliding column spring is in a compressed state. When the zinc liquid in the galvanizing pool is gradually consumed, the sliding column spring rises, driving the galvanizing pool to rise, thereby driving the top column and the inner slide to rise, and the inner slide spring is stretched, thereby driving the vertical rod to rise, thereby driving the vertical ratchet bar to rise, thereby driving the transmission ratchet, the inner transmission column and the inner gear to rotate, thereby driving the outer gear and the outer transmission column to rotate, thereby driving the transmission wheel to rotate, thereby driving the conveyor wheel to rotate through the inclined transmission belt, thereby driving the conveyor belt forward, moving the zinc block forward one grid, and the zinc block enters the galvanizing pool to replenish the zinc liquid. When the weight of the galvanizing pool increases, the galvanizing pool drops, the sliding column spring is compressed, and the inner slide drops under the rebound of the inner slide spring. At this time, the drop of the vertical ratchet bar will not drive the transmission ratchet to rotate, and the vertical tooth spring is compressed.

[0015] Furthermore, the scraper device includes side track plates fixedly installed on both sides of the sliding plate, the sliding plate slopes toward the liquid inlet groove on the galvanizing pool, a screw motor is fixedly installed on the side track plate, a screw is rotatably installed on the side track plate, the screw and the motor shaft of the screw motor are fixedly installed, a sliding frame is slidably installed on the side track plate, the sliding frame and the screw form a threaded transmission, a lifting slide column is slidably installed in the vertical groove of the sliding frame, a sliding plate is fixedly installed on the lifting slide column, a scraper is fixedly installed on the sliding plate, two track slide columns are fixedly installed on the sliding plate, the track slide column slides in the track of the side track plate, and a rotating plate is rotatably installed on the side track plate.

When the deck is transferred between various workstations, the pressing mechanism does not operate, and when the pressing mechanism presses the deck down, the transfer mechanism does not operate, thereby achieving high automation and high processing efficiency. (2) the feeding device provided in the present invention automatically adds zinc blocks to the galvanizing pool when the zinc liquid in the galvanizing pool is insufficient.

[0039] When the turntable ratchet 110 is out of mesh with the ratchet bar 126, the large trapezoidal block 124 begins to contact the small trapezoidal block 123.

[0043] The galvanizing pool 106 is filled with zinc liquid. When the zinc liquid is sufficient, the slide spring 105 is in a compressed state. When the zinc liquid in the galvanizing pool 106 is gradually consumed, the slide spring 105 rises, driving the galvanizing pool 106 to rise, thereby driving the top column 207 and the inner slide 206 to rise, and the inner slide spring 219 is stretched, thereby driving the vertical rod 208 to rise, thereby driving the vertical ratchet bar 209 to rise, thereby driving the transmission ratchet 212, the inner transmission column 211 and the inner gear 213 to rotate, thereby driving the outer gear 214 and the outer transmission column 215 to rotate.

At this time, the scraper 303 rises, and the scraper 303 will not scrape the zinc liquid back. When the sliding plate 307 returns to the end closest to the sliding frame 306, the sliding plate 307 falls, and the lifting slide 308 falls along the sliding frame 306, thereby driving the scraper 303 to fall, and the track slide 309 returns to the lower track of the side track plate 302, and the zinc liquid on the sliding plate 301 is repeatedly scraped into the galvanizing pool 106.

[0046] The working principle of the automatic galvanizing device for decks disclosed in the present invention is as follows: the deck to be galvanized is hung on a hook 116, the electric cylinder 108 is extended, and the push frame 125 is driven to slide along the bottom plate 101, thereby driving the ratchet bar 126 to move forward, and the ratchet bar 126 drives the turntable ratchet 110 to rotate, thereby driving the active shaft 109 and the active turntable 111 to rotate, thereby driving the connecting plate 114 to move forward through the transmission belt 112, and each time the connecting plate 114 is driven to move forward one station, when the ratchet bar 126 is disengaged from the turntable ratchet 110, the connecting plate 114 just moves forward one station, and the connecting plate 114 is provided with five stations, namely, the pickling station located in the pickling tank 102, the water washing station located in the water washing tank 103, the galvanizing station located in the galvanizing tank 106, the static station located in the lubricating plate 301 and the cooling station located in the cooling tank 107. When the turntable ratchet 110 is out of mesh with the ratchet bar 126, the large trapezoidal block 124 begins to contact the small trapezoidal block 123. As the electric cylinder 108 continues to extend, the large trapezoidal block 124 is driven forward, which pushes the small trapezoidal block 123 and the lower pressing frame 120 down. The inner spring 122 is compressed, and the lower pressing frame 120 descends to press the descending plate 115 and the hook 116 above the pickling tank 102, the water washing tank 103, the galvanizing tank 106 and the cooling tank 107 downward. The upper spring 118 is compressed, and the hook 116 above the pickling tank 102 brings the deck into the pickling tank 102, and the nozzles in the pickling tank 102 spray The deck is pickled with acid liquid, the hook 116 above the water washing tank 103 brings the deck into the water washing tank 103, the nozzle in the water washing tank 103 sprays high-pressure water to wash the deck, the hook 116 above the galvanizing tank 106 brings the deck into the zinc liquid in the galvanizing tank 106 for galvanizing, the hook 116 above the cooling tank 107 brings the deck into the cooling water in the cooling tank 107 to cool the galvanized deck, the hook 116 and the deck staying above the sliding plate 301 will not be pressed down, the deck is left stationary above the sliding plate 301, and the excess zinc liquid falls onto the sliding plate 301. After the electric cylinder 108 is extended to the farthest, it begins to retract, and the lower pressure frame 120 is reset under the rebound of the inner spring 122, and the descending plate 115 and the hook 116 are reset under the rebound of the upper spring 118, driving the deck to rise. When the electric cylinder 108 is retracting, the ratchet bar 126 will not drive the turntable ratchet 110 to rotate, and the ratchet spring 127 will be compressed. Finally, the electric cylinder 108 returns to the initial position and starts the next extension. The speed of the electric cylinder 108 is slow, so that each workstation has enough dwell time. The electric cylinder 108 continuously reciprocates and retracts. Each time the electric cylinder 108 retracts and retracts, it drives the connecting plate 114 to move forward one workstation, and the lower pressure frame 120 is pressed down once.The galvanizing pool 106 is filled with zinc liquid. When the zinc liquid is sufficient, the slide spring 105 is in a compressed state. When the zinc liquid in the galvanizing pool 106 is gradually consumed, the slide spring 105 rises, driving the galvanizing pool 106 to rise, thereby driving the top column 207 and the inner slide 206 to rise, and the inner slide spring 219 is stretched, thereby driving the vertical rod 208 to rise, thereby driving the vertical ratchet bar 209 to rise, thereby driving the transmission ratchet 212, the inner transmission column 211 and the inner gear 213 to rotate, thereby driving the outer gear 214 and the outer transmission column 215 to rotate. The inner slide 206 moves, thereby driving the transmission wheel 216 to rotate, thereby driving the conveying wheel 202 to rotate through the inclined transmission belt 217, thereby driving the conveyor belt 203 forward, and the zinc block 205 moves forward one grid, and the zinc block 205 enters the galvanizing pool 106 to replenish the zinc liquid. When the weight of the galvanizing pool 106 increases, the galvanizing pool 106 descends, the slide column spring 105 is compressed, and the inner slide 206 descends under the rebound of the inner slide spring 219. At this time, the vertical ratchet bar 209 descends and does not drive the transmission ratchet 212 to rotate, and the vertical tooth spring 210 is compressed. The zinc liquid falls onto the sliding plate 301, and the sliding plate 301 slopes toward the liquid inlet groove on the galvanizing pool 106. The screw motor 304 rotates to drive the screw 305 to rotate, thereby driving the sliding frame 306 to slide along the side track plate 302. The sliding of the sliding frame 306 drives the lifting slide 308 and the sliding plate 307 to slide, thereby driving the track slide 309 to slide in the lower track of the side track plate 302, thereby driving the scraper 303 to scrape the zinc liquid on the sliding plate 301 into the galvanizing pool 106. When the track slide 309 contacts the rotating plate 310, it will push the rotating plate 310 up and pass through the rotating plate 310. When the sliding frame 306 moves to the farthest end, the screw motor 304 The sliding plate 307 starts to reverse, driving the sliding frame 306 to move toward the screw motor 304, thereby driving the track slide 309 to slide in the groove of the side track plate 302, and the track slide 309 will slide over the rotating plate 310 to reach the upper track in the side track plate 302. At this time, the scraper 303 rises, and the scraper 303 will not scrape the zinc liquid back. When the sliding plate 307 returns to the end closest to the sliding frame 306, the sliding plate 307 falls, and the lifting slide 308 falls along the sliding frame 306, thereby driving the scraper 303 to fall, and the track slide 309 returns to the lower track of the side track plate 302, and the zinc liquid on the sliding plate 301 is repeatedly scraped into the galvanizing pool 106.
