Description

Technical Field

[0001] This application relates to the field of laser measurement technology, and in particular to a laser measurement device for manufacturing ship parts. Background Technology

[0002] Steel columns, as one of the ship components, are frequently used on ships, mainly as rudder posts, shafts, and supports. They are important components of the ship's power and support structure. During manufacturing, laser measurement of the curvature of steel columns is used to detect and correct potential deformation problems in a timely manner, thereby preventing ship safety accidents caused by structural instability.

[0003] A search revealed that patent CN223258884U proposes a steel column curvature measuring device. Each set of fixed seats is connected to a connection port in an annular air duct through an air guide pipe. The negative pressure fan inside the negative pressure air box is started, and the negative pressure air generated is sequentially matched with the air inlet on each set of fixed seats through the annular air duct. This allows dust near the two sides of the positioning ring to be sucked into the dust collection box from the air inlet when it approaches the fixed seat, thereby preventing dust from coming into contact with the laser scanner and reducing the frequency of disassembly, cleaning and maintenance of the laser scanner.

[0004] Although the device incorporates a negative pressure suction structure for dust removal from the laser scanner surface, the air inlet is located on the lower side of the scanner. This means it only effectively removes dust near the air inlet, failing to effectively remove dust from the top surface, thus limiting its cleaning effectiveness. Furthermore, the device only considers the laser scanner's own dust removal, neglecting the fact that dust and particulate impurities on the steel column itself can also interfere with laser scanning measurements. While those skilled in the art might consider high-pressure cleaning to remove stubborn particulate impurities and dust from the steel column surface before laser measurement, the fixed water volume during high-pressure cleaning means it cannot adjust the volume based on the column's diameter. Smaller diameter columns result in wasted water, while larger diameter columns suffer from insufficient water spray and inadequate cleaning. Summary of the Invention

[0005] Therefore, it is necessary to provide a laser measuring device for ship component manufacturing that can clean the steel column to be inspected and clean the laser scanner, addressing the aforementioned technical problems.

[0006] To achieve the above objectives, this application provides the following technical solution: a laser measuring device for manufacturing ship parts, comprising a base, a conveying device and a support frame mounted on the top of the base, a positioning ring mounted on the support frame, and a fixing seat mounted on the positioning ring, the fixing seat being used to mount a laser scanner; further comprising a cleaning component, a sanitation component, and a measurement component, wherein the cleaning component is mounted on the top of the base for cleaning the ship parts before measurement, the sanitation component is located at the support frame for cleaning the laser scanner, the measurement component is located on the cleaning component and is used for counting the number of ship parts being measured, and the cleaning component and the measurement component are driven by the cleaning component.

[0007] Preferably, the cleaning assembly includes a cleaning box mounted on the top of the base and a hollow column. A movable column is slidably connected inside the hollow column. The movable column is connected to a conveying device. The hollow column is connected to the bottom of the movable column by a No. 1 spring. The cleaning box has symmetrical through slots.

[0008] Preferably, a water pump is installed on the base, the water pump is connected to a water supply pipe, a circular high-pressure nozzle is installed in the cleaning tank via a support rod, the high-pressure nozzle is connected to a pipe, the water supply pipe is connected to the pipe via a water valve, the valve handle of the water valve is provided with teeth, a connecting rod is fixed on the conveying device, a rack is fixed on the connecting rod, and the rack meshes with the teeth.

[0009] Preferably, the cleaning component includes a horizontal plate fixed inside the cleaning tank, a drain outlet fixedly provided on the horizontal plate, and a water baffle hinged to the horizontal plate by a torsion spring hinge. The water baffle is used to block the drain outlet. A round rod is fixed inside one end of the water baffle, and both ends of the round rod extend out of the cleaning tank and are fixed with cams.

[0010] Preferably, a vertical rod is fixed to the bottom of the conveying device, a wedge block is fixed to the bottom of the vertical rod, and a wedge-shaped stop is slidably connected to the cleaning tank. The wedge-shaped stop is connected to the outer wall of the cleaning tank by a second spring.

[0011] Preferably, a U-shaped rod is slidably connected to the support frame, a cleaning ring is fixed to one end of the U-shaped rod, and a T-shaped rod is fixed to the other end of the U-shaped rod. The T-shaped rod is connected to a No. 3 spring on the cleaning tank.

[0012] Preferably, a gong is installed on the outer wall of the cleaning tank at the cam.

[0013] Preferably, the metering component includes a rotating shaft, which is rotatably mounted at the bottom of the cleaning tank. A water receiving plate is fixed to the outside of the rotating shaft, and an overflow groove is provided on the inner wall of the cleaning tank. One end of the rotating shaft extends out of the cleaning tank and is equipped with a winding reel.

[0014] Preferably, a release disc is rotatably mounted on the outer wall of the cleaning tank, a digital strip is wound around the outside of the release disc, and a hollow display frame is fixed to the outside of the cleaning tank, through which the digital strip passes.

[0015] Preferably, a sealing plate is installed on the side wall of the cleaning tank, and a drain pipe is installed at the bottom of the cleaning tank.

[0016] In summary, the present invention has the following beneficial effects: 1. The U-shaped rod moves on the support frame, carrying the cleaning ring and the cleaning cloth towards the laser scanner, thus wiping the top surface of the laser scanner. Combined with existing negative pressure dust collection, this improves the accuracy of laser measurement.

[0017] 2. When the diameter of the steel column being measured is large, the weight on the conveying device is greater, resulting in a greater descent. This causes the movable column to descend even further within the hollow column. At this point, the No. 1 spring is compressed, and the movable column descends even further via the connecting rod and rack. Consequently, the rotation angle of the meshing teeth and valve handle increases. An increased valve handle rotation angle enlarges the water flow path within the water valve. Conversely, a smaller diameter results in a lighter weight, leading to a smaller valve handle rotation angle and a smaller water flow path within the water valve. Thus, the weight of the steel column being measured enables active regulation of the water volume.

[0018] 3. The rushing water, upon impacting the water receiving plate, drives the rotating shaft and winding reel to rotate. The winding reel winds up the digital tape. Because the water accumulated on the horizontal plate maintains a constant volume and level, the angle at which the winding reel rotates is always the same after each discharge. At this angle, the length wound by the winding reel in one rotation is equal to the distance between two adjacent digital codes on the digital tape. Therefore, this design ensures that the number displayed in the frame matches the number of steel columns that have been scanned, facilitating the counting of the total number of steel columns that have completed laser scanning and enabling steel column counting control to meet production needs.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Example: Reference Figure 1 The laser measuring device for manufacturing ship parts shown in Figure 6 includes a base 11, a conveying device 12 and a support frame 13 mounted on the top of the base 11, a positioning ring 14 mounted on the support frame 13, a fixing seat 15 mounted on the positioning ring 14, and a laser scanner 16 mounted on the fixing seat 15. The number of conveying devices 12 is three sets, and the laser scanners 16 are distributed in a circular array along the positioning ring 14.

[0023] The distinguishing features of the laser measuring device of the present invention include a cleaning component, a cleaning component, and a measuring component. The cleaning component is installed on the top of the base 11 and is used to clean the ship parts before measurement. The cleaning component is located at the support frame 13 and is used to clean the laser scanner 16. The measuring component is located on the cleaning component and is used to count the number of ship parts being measured. The cleaning component and the measuring component are driven by the cleaning component.

[0024] It should be noted that the prior art document CN223258884U has already disclosed laser measurement, so this invention will not repeat it here; in addition, ship fittings specifically refer to cylindrical column parts such as steel columns.

[0025] The distinguishing features of the present invention are described in detail below: As one embodiment of this invention, the cleaning assembly includes a cleaning box 201 mounted on the top of the base 11 and a hollow column 202. A movable column 203 is slidably connected inside the hollow column 202, and the movable column 203 is connected to the conveying device 12.

[0026] The hollow column 202 is connected to the bottom of the movable column 203 by a first spring 204. The first spring 204 realizes the reset of the movable column 203 after it descends.

[0027] The cleaning chamber 201 has symmetrical through slots 205, which facilitates the steel column to pass through the through slots 205 and complete the cleaning before testing inside the cleaning chamber 201.

[0028] A sealing plate 17 is installed on the side wall of the cleaning tank 201, and a drain pipe 18 is installed at the bottom of the cleaning tank 201. The parts inside the cleaning tank 201 can be repaired or replaced by removing the sealing plate 17, provided that there is no water inside and the work is stopped. The drain pipe 18 facilitates the drainage of water from the bottom of the cleaning tank 201 during operation.

[0029] The above will first Figure 1 The hollow column 202, movable column 203, and conveying device 12 on the right side are disassembled to make room for the opening of the sealing plate 17. Then the sealing plate 17 is opened to allow for the repair or replacement of parts inside the cleaning box 201.

[0030] A water pump 206 is installed on the base 11. The water pump 206 is connected to a water supply pipe 207. A circular high-pressure nozzle 209 is installed in the cleaning tank 201 through a support rod 208. The high-pressure nozzle 209 is connected to a pipe 210. The water supply pipe 207 and the pipe 210 are connected through a water valve 211.

[0031] The valve handle of the water valve 211 is provided with teeth 212, and the conveying device 12 is fixed with a connecting rod 213. The connecting rod 213 is fixed with a rack 214, and the rack 214 meshes with the teeth 212.

[0032] It should be explained that the diameter of the steel column is selected based on the load it bears, and the height is constrained by the distance between the decks of the ship to keep it uniform. Therefore, there are a large number of steel columns of the same height but different diameters in the ship's rudder, shafting, and deck support. This invention is designed based on this scenario.

[0033] It should be noted that as the diameter of the steel column increases, the area to be cleaned on its outer perimeter also increases, and the required water volume increases accordingly; conversely, it decreases as the diameter decreases.

[0034] Specifically, during steel column inspection, workers will place the front end of the steel column to be inspected along... Figure 1The steel column is placed horizontally through the right-side through-slot 205, passing through the cleaning box 201 and the laser scanning array, and then placed on the third conveyor device 12 on the left. At this time, the steel column is located above the three sets of conveyor devices 12. The front end of the steel column is for assembly and docking. This section has extra machining allowance and will be machined off later. It does not need to be inspected by laser scanning. Therefore, the front end of the steel column (which accounts for a very small proportion of the total length) can be placed directly on the three sets of conveyor devices 12 without being cleaned.

[0035] The larger the diameter of the steel column of the same height, the greater its weight. For example, when the diameter of the steel column being measured is large, the weight on the conveying device 12 is greater, and it descends more. This causes the movable column 203 to descend more within the hollow column 202. At this time, the first spring 204 is compressed, and the movable column 203 descends more through the connecting rod 213 and the rack 214. This increases the rotation angle of the meshing teeth 212 and the valve handle. The increased rotation angle of the valve handle increases the water flow path within the water valve 211. Conversely, a smaller diameter means a lighter weight, resulting in a smaller rotation angle of the valve handle and a smaller water flow path within the water valve 211. Thus, the weight of the steel column being measured enables active regulation of the water volume. This active regulation solves the problems of water waste caused by cleaning smaller diameter steel columns with a fixed spray volume, and insufficient water spray and incomplete cleaning caused by cleaning larger diameter steel columns. The pump 206 is connected to an external water source and sends water through the water pipe 207 into the pipe 210, which then delivers the water to the high-pressure nozzle 209 and sprays it onto the steel column. This achieves high-pressure cleaning of stubborn particulate impurities and dust on the steel column. The larger the diameter of the steel column, the greater the amount of water sprayed after the above adjustment. This allows for the handling of steel columns of different diameters. The cleaning process prevents external impurities from interfering with the laser scanning, thus improving the accuracy of the measurement.

[0036] As one embodiment of this invention, the cleaning component includes a horizontal plate 301, which is fixed inside the cleaning tank 201. A drain outlet 302 is fixedly provided on the horizontal plate 301, which facilitates the drainage of water accumulated on the horizontal plate 301.

[0037] A water baffle 304 is hinged to the horizontal plate 301 via a torsion spring hinge 303. The water baffle 304 is used to block the drain outlet 302, and the torsion spring hinge 303 is used to reset the water baffle 304 after rotation.

[0038] A round rod 305 is fixed inside one end of the baffle plate 304. Both ends of the round rod 305 extend out of the cleaning tank 201 and are fixed with cams 306.

[0039] A vertical rod 307 is fixed to the bottom of the conveying device 12, and a wedge block 308 is fixed to the bottom of the vertical rod 307. A wedge-shaped stop bar 309 is slidably connected to the cleaning tank 201. The wedge-shaped stop bar 309 is connected to the outer wall of the cleaning tank 201 by a second spring 310.

[0040] A U-shaped rod 311 is slidably connected to the support frame 13. A cleaning ring 312 is fixed to one end of the U-shaped rod 311, and a T-shaped rod 313 is fixed to the other end of the U-shaped rod 311. The T-shaped rod 313 is connected to the No. 3 spring 314 on the cleaning box 201.

[0041] A gong 315 is installed on the outer wall of the cleaning box 201 at the cam 306. When the gong 315 is reset, the cam 306 strikes and makes a sound, reminding the workers to prepare to install a new steel column.

[0042] Specifically, when the middle conveying device 12 is pressed down by the weight of the steel column, it will bring the wedge block 308 down through the vertical rod 307. In the initial state, the wedge rod 309 is offset from the baffle plate 304. When the wedge block 308 descends, it will press the wedge rod 309 and compress the second spring 310. The compressed wedge rod 309 comes to the bottom of the baffle plate 304, which helps to block the baffle plate 304 and close the drain outlet 302, thereby storing the water sprayed by the high pressure nozzle 209 above the horizontal plate 301. It should be noted that this device is designed according to actual testing conditions. Even the smallest diameter steel column cleaning will spray water that exceeds the overflow trough 405. However, due to the existence of the overflow trough 405, it can play a balancing role. The overflow trough 405 is an empty trough opened in the wall cavity of the cleaning tank 201. Water on the horizontal plate 301 that exceeds the overflow trough 405 enters from the opening above the overflow trough 405, then flows along the overflow trough 405, and then is discharged from the opening below the overflow trough 405 to the bottom of the horizontal plate 301, and then is discharged through the drain pipe 18. Under the action of the overflow trough 405, the water accumulated on the horizontal plate 301 always maintains a uniform water volume and water level. After the steel column is measured, it is removed from the conveying device 12. At this time, the wedge block 308 will rise and reset. Then, the second spring 310 will cause the wedge rod 309 to leave the bottom of the water baffle 304. Then, the water accumulated on the horizontal plate 301 presses down on the water baffle 304 and flips it to open the drain outlet 302. The force exerted by the accumulated water on the water baffle 304 is greater than the resistance of the torsion spring hinge 303. After flipping, the water accumulated on the horizontal plate 301 will rush down. When the baffle plate 304 rotates and opens, it rotates the round rod 305 and the cam 306. The cam 306 rotates and presses against the T-shaped rod 313 and acts on the U-shaped rod 311. Then the U-shaped rod 311 moves on the support frame 13 and moves with the cleaning ring 312. A cleaning cloth is attached to the surface of the cleaning ring 312 by Velcro. The cleaning ring 312 and the cleaning cloth move toward the laser scanner 16 and wipe the top surface of the laser scanner 16 to improve the accuracy of laser scanning. Moreover, this wiping is only achieved through mechanical linkage after the steel column is removed and will not affect the normal scanning operation. When the water on the horizontal plate 301 is almost drained, the compressed No. 3 spring 314, along with the T-shaped rod 313, U-shaped rod 311, and cleaning ring 312, returns to its original position. The cam 306, upon resetting, strikes the gong 315, causing it to make a sound to remind the worker to load materials.

[0043] As one embodiment of this invention, the metering component includes a rotating shaft 401, which is rotatably mounted on the bottom of the cleaning tank 201. A water receiving plate 402 is fixed to the outside of the rotating shaft 401. An overflow groove 405 is provided on the inner wall of the cleaning tank 201. One end of the rotating shaft 401 extends out of the cleaning tank 201 and is equipped with a winding reel 403, which is used to pull and wind up the digital tape 406.

[0044] A release disc 404 is rotatably mounted on the outer wall of the cleaning tank 201. A digital tape 406 is wound around the outside of the release disc 404. A hollow display frame 407 is fixed to the outside of the cleaning tank 201. The digital tape 406 passes through the display frame 407. The release disc 404 facilitates the installation of the rolled digital tape 406.

[0045] Specifically, as described above, after the baffle plate 304 flips, the water accumulated on the horizontal plate 301 plunges down and acts on the water receiving plate 402. The maximum tilt angle of the baffle plate 304 is above the water receiving plate 402, so it will not obstruct the rotation of the water receiving plate 402. After the plunging water acts on the water receiving plate 402, it will drive the rotating shaft 401 and the winding reel 403 to rotate. The winding reel 403 winds up the digital tape 406. The digital tape 406 has equidistantly distributed numerical codes of 0, 1, 2, 3, etc., which increase by "+1". Initially, 0 is located within the display frame 407. Since the water accumulated on the horizontal plate 301 always maintains a uniform water volume and level, each time the water is discharged, it acts on the water receiving plate 402, causing the water receiving plate 402, the rotating shaft 401, and the winding reel 403 to rotate at the same angle. At this angle, the length of winding of the winding reel 403 in one rotation is equal to the distance between two adjacent digital codes. Therefore, this design ensures that the number appearing in the display frame 407 is the same as the number of steel columns that have been scanned, which facilitates the counting of the total number of steel columns that have been laser scanned and detected, realizing steel column counting control and meeting production needs.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
