Description

Technical Field

[0001] The invention relates to the technical field of fender size measurement, and in particular to an automatic measurement device for ship fender size. Background Art

[0002] Ship fenders are protective devices installed on the side of the ship, and are designed to protect the side walls of the ship from collision, friction and other potential damage. Fenders are usually made of strong and durable materials to absorb or reduce the impact of external impacts on the hull. Fenders help extend the service life of the ship and provide critical protection during operations such as docking, berthing, loading and unloading of cargo. When selecting fenders, it is necessary to consider the size, purpose and operating environment of the ship. Therefore, after the fenders are processed, their dimensions need to be measured, mainly to measure whether their length and width meet the requirements. In the existing technology, the dimensions of the fenders are mainly measured manually, which has low measurement efficiency and low degree of automation, and cannot achieve continuous batch automatic measurement. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an automatic measuring device for the size of a ship fender, comprising a main frame device, the main frame device comprising a supporting column, a middle plate and an upper plate are fixedly mounted on the supporting column, the main frame device is used to measure the length of the ship fender, the main frame device is provided with a plate feeding device and two width measuring devices, the width measuring device comprises a measuring seat, the measuring seat is fixedly mounted on the middle plate, the width measuring device is used to measure the width of the ship fender, the plate feeding device comprises a feeding box, the feeding box is fixedly mounted on the upper plate, and the plate feeding device is used to continuously feed the ship fender.

[0004] Furthermore, the main frame device includes a base plate fixedly installed on the support column, a middle plate and an upper plate fixedly installed, a plate outlet slope fixedly installed on the base plate, a lower suction cylinder fixedly installed on the base plate, a suction cup fixedly installed on the top of the lower suction cylinder, and two plate support mechanisms are arranged on the middle plate.

[0005] Furthermore, the support mechanism includes a splint motor fixedly mounted on the middle plate, a motor gear fixedly mounted on the motor shaft of the splint motor, a sliding column fixedly mounted on the middle plate, a support plate slidably mounted on the sliding column, a screw rod fixedly mounted on the support plate, the screw rod meshing with the motor gear, and a long measuring mechanism is arranged on the support plate.

[0006] Furthermore, the long measuring mechanism includes a push block fixedly mounted on a support plate, a long measuring seat fixedly mounted on the support plate, a long sliding column slidably mounted on the long measuring seat, a long detection plate fixedly mounted on the long sliding column, a long spring arranged between the long detection plate and the long measuring seat, and a long sensor fixedly mounted on the long measuring seat.

[0007] When the ship fender falls onto the support plate, the support plate is located below the ship fender in the initial position, and the ship fender is supported by the support plate. At the same time, the long detection plate is still some distance away from the ship fender. The rotation of the clamping plate motor drives the motor gear to rotate, thereby driving the support plate to slide inward along the sliding column through the screw rod. When the long detection plate contacts the ship fender, the support plate continues to move inward, the long spring is compressed, and the long detection plate slides along the long sliding column. When the long spring clamps the ship fender, the long detection plate no longer moves. At this time, the long detection plate enters the sensing range of the long sensor, and the long sensor determines the inward movement distance of the support plate compared to the initial position, thereby determining the length of the ship fender.

[0008] When the ship fender inspection is completed, the lower suction cylinder rises, so that the suction cup contacts the bottom of the ship fender, and the ship fender is sucked by the suction cup. At the same time, the clamping plate motor rotates to drive the motor gear to rotate, thereby driving the support plate to move to the outermost side through the screw rod. At this time, the support plate is no longer under the ship fender, and the lower suction cylinder contracts to place the ship fender on the middle plate. The ship fender slides out through the middle plate, and then the clamping plate motor rotates to drive the support plate back to the initial position.

[0009] Furthermore, the width measuring device includes a side motor fixedly mounted on the measuring seat, a lower screw rod fixedly mounted on the motor shaft of the side motor, a lower sliding rail fixedly mounted on the measuring seat, a wide measuring plate slidably mounted on the lower sliding rail, the wide measuring plate and the lower screw rod form a threaded transmission, a wide sensor fixedly mounted on the wide measuring plate, a wide sliding column slidably mounted on the wide measuring plate, a wide detection plate fixedly mounted on the wide sliding column, and a wide spring arranged between the wide detection plate and the wide measuring plate.

[0010] When the ship fender falls onto the width sensor, the side motor rotates to drive the lower screw to rotate, thereby driving the wide measuring plate to slide inward along the lower slide rail, so that the wide detection plate moves toward the ship fender. After the wide detection plate contacts the ship fender, the wide measuring plate continues to move inward, causing the wide spring to be compressed. When the wide detection plates at both ends contact the width sensor, the width sensor is used to determine the distance the wide measuring plate has moved inward compared to the initial position, thereby determining the width of the ship fender.

[0011] Furthermore, the plate feeding device includes a positive spring seat fixedly installed on the supporting column, a positive sliding column is slidably installed in the positive spring seat, a positive clamping plate is fixedly installed on the positive sliding column, a positive compression spring is arranged between the positive clamping plate and the positive spring seat, an internal threaded sleeve is fixedly installed on the supporting column, an internal thread is arranged in the internal threaded sleeve, a positive threaded rod is rotatably installed in the internal threaded sleeve, an external thread is arranged on the positive threaded rod, a threaded transmission is formed between the positive threaded rod and the internal threaded sleeve, a positive knob is fixedly installed on the positive threaded rod, a side clamping mechanism is arranged on the feed box, and two plate releasing mechanisms are arranged on the positive clamping plate.

[0012] Furthermore, the side clamping mechanism includes a side spring seat fixedly installed on the feed box, a side sliding column is slidably installed on the side spring seat, a side clamping plate is fixedly installed on the side sliding column, a side compression spring is arranged between the side clamping plate and the side spring seat, a side internal threaded sleeve is fixedly installed on the feed box, an internal thread is arranged in the side internal threaded sleeve, a side threaded rod is rotatably installed on the side internal threaded sleeve, an external thread is arranged on the side threaded rod, a threaded transmission is formed between the side threaded rod and the side internal threaded sleeve, a side knob is fixedly installed on the side threaded rod, and a ship fender is placed between the side clamping plate and the front clamping plate.

[0013] Furthermore, the plate placing mechanism includes a side discharge rack, a lower column and an upper column fixedly mounted on the positive clamping plate, a top electric cylinder fixedly mounted on the side discharge rack, a lifting push block slidably mounted in the side discharge rack, the lifting push block is fixedly mounted on the top of the top electric cylinder, a lower blocking plate slidably mounted on the lower column, an upper blocking plate slidably mounted on the upper column, a lower column spring is arranged between the lower blocking plate and the positive clamping plate, an upper column spring is arranged between the upper blocking plate and the positive clamping plate, an upper roller is rotatably mounted in the upper blocking plate, a lower roller is rotatably mounted in the lower blocking plate, the lifting push block is slidably mounted on the upper roller, and the lifting push block is slidably mounted on the lower roller.

[0014] Furthermore, the ends of the upper blocking plate and the lower blocking plate are provided with an upper slope surface and a lower slope surface.

[0015] The ship fender to be measured is stacked between the side clamping plate and the positive clamping plate. By turning the positive knob and the positive threaded rod, the positive clamping plate and the positive sliding column can be pushed to slide inward along the feed box through the positive threaded rod, thereby adjusting the distance between the two sets of positive clamping plates. Similarly, by turning the side knob and the side threaded rod, the side clamping plate and the side sliding column can be pushed to slide inward along the feed box through the side threaded rod, thereby adjusting the distance between the two sets of side clamping plates, thereby adapting to different sizes of ship fenders.

[0016] In the initial state, the side sliding column holds the lowest ship fender, and the lower column spring is in a compressed state. At this time, the upper blocking plate retracts. When the ship fender needs to be placed on the wide sensor, the top electric cylinder contracts, driving the lifting push block to rise, so that the lifting push block leaves the front of the lower roller, and the lower column spring rebounds, driving the lower blocking plate and the lower roller to slide outward along the lower column, so that the lower blocking plate leaves the bottom of the ship fender. At the same time, the lifting push block drives the upper roller and the upper blocking plate to slide inward along the upper column, and the upper column spring is compressed. The upper blocking plate is inserted between the lowest and second lowest ship fenders. At this time, the lowest ship fender falls on the wide sensor, and the second lowest ship fender is supported by the upper blocking plate. Then the top electric cylinder extends, driving the lower roller and the lower blocking plate to slide inward along the lower column, and the lower blocking plate reaches under the ship fender, and the upper column spring rebounds, driving the upper blocking plate and the upper roller to slide outward along the upper column, and the upper blocking plate leaves under the ship fender. At this time, all the ship fenders are stacked on the lower blocking plate, ready for the next placement.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) the main frame device provided in the present invention can measure the length of the ship fender, and measure the width of the ship fender through the width measuring device.

DETAILED DESCRIPTION

[0033] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] Example: Reference Figure 1-Figure 14 A ship fender size automatic measuring device comprises a main frame device, the main frame device comprises a support column 101, a middle plate 103 and an upper plate 105 are fixedly mounted on the support column 101, the main frame device is used to measure the length of the ship fender, a board feeding device and two width measuring devices are arranged on the main frame device, the width measuring device comprises a measuring seat 201, the measuring seat 201 is fixedly mounted on the middle plate 103, the width measuring device is used to measure the width of the ship fender, the board feeding device comprises a feeding box 301, the feeding box 301 is fixedly mounted on the upper plate 105, and the board feeding device is used to continuously feed the ship fender.

[0035] like Figure 2-Figure 6 As shown, the main frame device includes a base plate 102 fixedly mounted on a support column 101, a middle plate 103 and an upper plate 105 fixedly mounted, a plate discharge slope 104 fixedly mounted on the base plate 102, a lower suction cylinder 117 fixedly mounted on the base plate 102, a suction cup 118 fixedly mounted on the top of the lower suction cylinder 117, and two plate support mechanisms are arranged on the middle plate 103.

[0036] like Figure 2-Figure 6 As shown, the support mechanism includes a splint motor 106 fixedly mounted on the middle plate 103, a motor gear 107 fixedly mounted on the motor shaft of the splint motor 106, a sliding column 110 fixedly mounted on the middle plate 103, a support plate 109 slidably mounted on the sliding column 110, a screw rod 108 fixedly mounted on the support plate 109, the screw rod 108 meshes with the motor gear 107, and a long measuring mechanism is arranged on the support plate 109.

[0037] like Figure 2-Figure 6 As shown, the long measuring mechanism includes a push block 116 fixedly mounted on a support plate 109, a long measuring seat 111 is fixedly mounted on the support plate 109, a long sliding column 112 is slidably mounted on the long measuring seat 111, a long detection plate 114 is fixedly mounted on the long sliding column 112, a long spring 113 is arranged between the long detection plate 114 and the long measuring seat 111, and a long sensor 115 is fixedly mounted on the long measuring seat 111.

[0038] When the ship fender 4 falls onto the support plate 109, the support plate 109 is located below the ship fender 4 in the initial position, and the ship fender 4 is supported by the support plate 109. At the same time, the long detection plate 114 is still some distance away from the ship fender 4, and the rotation of the clamping plate motor 106 drives the motor gear 107 to rotate, thereby driving the support plate 109 to slide inward along the sliding column 110 through the screw rod 108. When the long detection plate 114 contacts the ship fender 4, the support plate 109 continues to move inward, the long spring 113 is compressed, and the long detection plate 114 slides along the long sliding column 112. When the long spring 113 clamps the ship fender 4, the long detection plate 114 no longer moves. At this time, the long detection plate 114 enters the sensing range of the long sensor 115, and the long sensor 115 determines the inward movement distance of the support plate 109 compared to the initial position, thereby determining the length of the ship fender 4.

[0039] When the inspection of the ship fender 4 is completed, the lower suction cylinder 117 rises, so that the suction cup 118 contacts the bottom of the ship fender 4, and the ship fender 4 is sucked by the suction cup 118. At the same time, the clamping motor 106 rotates to drive the motor gear 107 to rotate, thereby driving the support plate 109 to move to the outermost side through the screw rod 108. At this time, the support plate 109 is no longer located under the ship fender 4, and the lower suction cylinder 117 contracts to place the ship fender 4 on the middle plate 103. The ship fender 4 slides out through the middle plate 103, and then the clamping motor 106 rotates to drive the support plate 109 back to the initial position.

[0040] like Figure 7-Figure 9 As shown, the width measuring device includes a side motor 202 fixedly mounted on a measuring seat 201, a lower screw rod 203 fixedly mounted on the motor shaft of the side motor 202, a lower sliding rail 204 fixedly mounted on the measuring seat 201, a wide measuring plate 205 slidably mounted on the lower sliding rail 204, the wide measuring plate 205 and the lower screw rod 203 form a threaded transmission, a wide sensor 209 fixedly mounted on the wide measuring plate 205, a wide sliding column 206 slidably mounted on the wide measuring plate 205, a wide detection plate 208 fixedly mounted on the wide sliding column 206, and a wide spring 207 is arranged between the wide detection plate 208 and the wide measuring plate 205.

[0041] When the ship fender 4 falls onto the width sensor 209, the side motor 202 rotates to drive the lower screw 203 to rotate, thereby driving the wide measuring plate 205 to slide inward along the lower slide rail 204, so that the wide detection plate 208 moves toward the ship fender 4. After the wide detection plate 208 contacts the ship fender 4, the wide measuring plate 205 continues to move inward, causing the wide spring 207 to be compressed. When the wide detection plates 208 at both ends are in contact with the width sensor 209, the width sensor 209 is used to determine the distance that the wide measuring plate 205 moves inward compared to the initial position, thereby determining the width of the ship fender 4.

[0043] like Figure 10-Figure 14As shown, the side clamping mechanism includes a side spring seat 310 fixedly mounted on the feed box 301, a side sliding column 309 is slidably mounted on the side spring seat 310, a side clamping plate 308 is fixedly mounted on the side sliding column 309, a side compression spring 311 is arranged between the side clamping plate 308 and the side spring seat 310, a side internal threaded sleeve 314 is fixedly mounted on the feed box 301, an internal thread is arranged in the side internal threaded sleeve 314, a side threaded rod 312 is rotatably mounted on the side internal threaded sleeve 314, an external thread is arranged on the side threaded rod 312, a threaded transmission is formed between the side threaded rod 312 and the side internal threaded sleeve 314, a side knob 313 is fixedly mounted on the side threaded rod 312, and a ship fender 4 is placed between the side clamping plate 308 and the front clamping plate 307.

[0044] like Figure 10-Figure 14 As shown, the plate placing mechanism includes a side discharge rack 315, a lower column 316 and an upper column 320 fixedly mounted on the positive clamping plate 307, a top electric cylinder 322 is fixedly mounted on the side discharge rack 315, a lifting push block 323 is slidably mounted in the side discharge rack 315, the lifting push block 323 is fixedly mounted on the top of the top electric cylinder 322, a lower blocking plate 319 is slidably mounted on the lower column 316, an upper blocking plate 318 is slidably mounted on the upper column 320, a lower column spring 317 is arranged between the lower blocking plate 319 and the positive clamping plate 307, an upper column spring 321 is arranged between the upper blocking plate 318 and the positive clamping plate 307, an upper roller 324 is rotatably mounted in the upper blocking plate 318, a lower roller 325 is rotatably mounted in the lower blocking plate 319, the lifting push block 323 is slidably mounted on the upper roller 324, and the lifting push block 323 is slidably mounted on the lower roller 325.

[0045] like Figure 10-Figure 14 As shown, the ends of the upper blocking plate 318 and the lower blocking plate 319 are provided with an upper slope surface and a lower slope surface.

[0046] The ship fender 4 to be measured is stacked between the side clamping plate 308 and the positive clamping plate 307. By rotating the positive knob 305 and the positive threaded rod 304, the positive clamping plate 307 and the positive sliding column 326 can be pushed to slide inward along the feed box 301 through the positive threaded rod 304, so as to adjust the distance between the two groups of positive clamping plates 307. Similarly, by rotating the side knob 313 and the side threaded rod 312, the side clamping plate 308 and the side sliding column 309 can be pushed to slide inward along the feed box 301 through the side threaded rod 312, so as to adjust the distance between the two groups of side clamping plates 308, so as to adapt to different sizes of ship fenders 4.

[0047] In the initial state, the side sliding column 309 holds the lowest ship fender 4, and the lower column spring 317 is in a compressed state. At this time, the upper blocking plate 318 is retracted. When the ship fender 4 needs to be placed on the wide sensor 209, the top electric cylinder 322 contracts, driving the lifting push block 323 to rise, so that the lifting push block 323 leaves the front of the lower roller 325, and the lower column spring 317 rebounds, driving the lower blocking plate 319 and the lower roller 325 to slide outward along the lower column 316, so that the lower blocking plate 319 leaves the bottom of the ship fender 4. At the same time, the lifting push block 323 drives the upper roller 324 and the upper blocking plate 318 to slide inward along the upper column 320, and the upper column spring 321 The upper blocking plate 318 is compressed and inserted between the lowest and second-lower ship fenders 4. At this time, the lowest ship fender 4 falls onto the wide sensor 209, and the second-lower ship fender 4 is supported by the upper blocking plate 318. Then the top electric cylinder 322 extends, driving the lower roller 325 and the lower blocking plate 319 to slide inward along the lower column 316, and the lower blocking plate 319 reaches the bottom of the ship fender 4, and the upper column spring 321 rebounds, driving the upper blocking plate 318 and the upper roller 324 to slide outward along the upper column 320, and the upper blocking plate 318 leaves the bottom of the ship fender 4. At this time, all the ship fenders 4 are stacked on the lower blocking plate 319, ready for the next board placement.

[0048] The working principle of the automatic measurement device for the size of a ship fender disclosed in the present invention is as follows: the ship fender 4 to be measured is stacked between the side clamping plate 308 and the front clamping plate 307, and the front clamping plate 307 and the front sliding column 326 can be pushed to slide inward along the feed box 301 by rotating the front knob 305 and the front threaded rod 304, thereby adjusting the distance between the two groups of front clamping plates 307. Similarly, by rotating the side knob 313 and the side threaded rod 312, the side clamping plate 308 and the side sliding column 309 can be pushed to slide inward along the feed box 301 by the side threaded rod 312, thereby adjusting the distance between the two groups of side clamping plates 308, thereby adapting to different sizes of ship fenders 4. In the initial state, the side sliding column 309 holds the lowest ship fender 4, and the lower column spring 317 is in a compressed state. At this time, the upper blocking plate 318 is retracted. When the ship fender 4 needs to be placed on the wide sensor 209, the top electric cylinder 322 contracts, driving the lifting push block 323 to rise, so that the lifting push block 323 leaves the front of the lower roller 325, and the lower column spring 317 rebounds, driving the lower blocking plate 319 and the lower roller 325 to slide outward along the lower column 316, so that the lower blocking plate 319 leaves the bottom of the ship fender 4. At the same time, the lifting push block 323 drives the upper roller 324 and the upper blocking plate 318 to slide inward along the upper column 320, and the upper column spring 321 The upper blocking plate 318 is compressed and inserted between the lowest and second-lower ship fenders 4. At this time, the lowest ship fender 4 falls onto the wide sensor 209, and the second-lower ship fender 4 is supported by the upper blocking plate 318. Then the top electric cylinder 322 extends, driving the lower roller 325 and the lower blocking plate 319 to slide inward along the lower column 316, and the lower blocking plate 319 reaches the bottom of the ship fender 4, and the upper column spring 321 rebounds, driving the upper blocking plate 318 and the upper roller 324 to slide outward along the upper column 320, and the upper blocking plate 318 leaves the bottom of the ship fender 4. At this time, all the ship fenders 4 are stacked on the lower blocking plate 319, ready for the next board placement. When the ship fender 4 falls onto the support plate 109, the support plate 109 is located below the ship fender 4 in the initial position, and the ship fender 4 is supported by the support plate 109. At the same time, the long detection plate 114 is still some distance away from the ship fender 4, and the rotation of the clamping plate motor 106 drives the motor gear 107 to rotate, thereby driving the support plate 109 to slide inward along the sliding column 110 through the screw rod 108. When the long detection plate 114 contacts the ship fender 4, the support plate 109 continues to move inward, the long spring 113 is compressed, and the long detection plate 114 slides along the long sliding column 112. When the long spring 113 clamps the ship fender 4, the long detection plate 114 no longer moves. At this time, the long detection plate 114 enters the sensing range of the long sensor 115, and the long sensor 115 determines the inward movement distance of the support plate 109 compared to the initial position, thereby determining the length of the ship fender 4.When the ship fender 4 falls onto the width sensor 209, the side motor 202 rotates to drive the lower screw 203 to rotate, thereby driving the wide measuring plate 205 to slide inward along the lower slide rail 204, so that the wide detection plate 208 moves toward the ship fender 4. After the wide detection plate 208 contacts the ship fender 4, the wide measuring plate 205 continues to move inward, causing the wide spring 207 to be compressed. When the wide detection plates 208 at both ends are in contact with the width sensor 209, the width sensor 209 is used to determine the distance that the wide measuring plate 205 moves inward compared to the initial position, thereby determining the width of the ship fender 4. When the inspection of the ship fender 4 is completed, the lower suction cylinder 117 rises, so that the suction cup 118 contacts the bottom of the ship fender 4, and the ship fender 4 is sucked by the suction cup 118. At the same time, the clamping motor 106 rotates to drive the motor gear 107 to rotate, thereby driving the support plate 109 to move to the outermost side through the screw rod 108. At this time, the support plate 109 is no longer located under the ship fender 4, and the lower suction cylinder 117 contracts to place the ship fender 4 on the middle plate 103. The ship fender 4 slides out through the middle plate 103, and then the clamping motor 106 rotates to drive the support plate 109 back to the initial position.
