[0002] As an important protective device of water facilities such as ports and wharfs, the conical rubber fender plays a role in buffering, collision prevention and protection when the ship is berthed. Its performance is directly related to the safety and service life of the port facilities. With the rapid development of the shipping industry, the tonnage of ships is increasing, and the performance requirements of the fender system are also increasing. Regular detection can timely find problems such as rubber aging and structural damage, and prevent ship collision accidents caused by fender failure. At the same time, standardized detection can also prolong the service life of the fender and reduce the operating cost of the port.

[0003] In related technologies, according to the detection technical standards and specifications (such as GB / T 21537-2008 "Conical Rubber Fender", JT / T 4-2019 "Port Engineering Rubber Fender", ASTM D2000 Rubber Material Standard, etc.), the conical rubber fender detection mainly includes the following items: 1. Appearance inspection: surface cracks, wear, deformation, etc.; 2. Size measurement: key dimensions such as height, diameter, taper, etc.; 3. Physical property test: hardness, tensile strength, elongation, etc.; 4. Aging performance evaluation; 5. Internal structure inspection: whether there are delamination, bubbles and other defects; 6. Connection component inspection: corrosion condition of bolt, anchor and other metal parts.

[0004] However, in actual detection, the principle of "first appearance and then internal, first overall and then local" should be followed. When detecting the size of the conical rubber fender, manual operation with a conventional measuring tool such as a tape measure is required.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0022] Please refer to Figures 1 to 4 The present application provides the following technical solutions: The conical rubber fender detection device comprises a detection frame 1, an arc-shaped assembly 2, a rotating assembly 3 and a detection assembly 4. The detection frame 1 is connected with an external support device and is transported to a position where the conical fender 100 to be detected is located on the anti-collision wall 200 by the external device. The detection frame 1 is placed and pushed from top to bottom by the external device to the conical fender 100 to be detected and is attached to the side of the anti-collision wall 200 provided with the conical fender 100. The arc-shaped assembly 2 is connected with the detection frame 1 and can slide in the horizontal direction. The arc-shaped assembly 2 serves as the support structure of the rotating assembly 3 and also drives the rotating assembly 3 to move along the axial direction of the conical fender 100. The rotating assembly 3 is slidingly connected with the arc-shaped assembly 2 and is arranged on the inner side of the arc-shaped assembly 2. The rotating assembly 3 performs reciprocating circumferential motion in the radial direction of the conical fender 100. The rotating assembly 3 serves as the support structure of the detection assembly 4, and the detection assembly 4 is arranged on the rotating assembly 3. The detection end of the detection assembly 4 extends towards the inner side of the rotating assembly 3, that is, the side where the conical fender 100 is located. The central angle of the detection assembly 2 can be equal to or slightly greater than 180°. In addition, a rectangular positioning groove 11 is formed in the lower part of the detection frame 1. The lower end of the positioning groove 11 is an open end, and the horizontal sides and the inner top of the positioning groove 11 can be tangent to the outer wall of the base of the conical fender 100. The center of the circle corresponding to the positioning groove 11 is coaxially arranged with the arc-shaped assembly 2. The arc-shaped assembly 2 is coaxially arranged with the inscribed circle of the positioning groove 11 by the center determined by the positioning groove 11, so that the arc-shaped assembly 2 and the conical fender 100 are easily positioned.

[0023] The conical fender 100 is usually installed on the outside of the anti-collision wall of the wharf, forming the assembly form shown in the figure. Figure 1 The conical fender 100 directly bears the impact force of the ship and serves as a buffer structure when the ship body contacts the anti-collision wall 200. When the conical fender 100 is detected, the detection frame 1 is moved from top to bottom along the side of the anti-collision wall 200 by the external driving device such as the corresponding carrier or carrier frame, etc., so that the detection frame 1 drives the arc-shaped assembly 2 to move to the upper side of the conical fender 100, and the detection frame 1 is attached to the outer wall of the anti-collision wall. By means of the positioning groove 11 of the detection frame 1, the arc-shaped assembly 2 is coaxially aligned with the conical fender 100, so that the rotating assembly 3 and the detection assembly 4 are positioned for subsequent detection work.

[0024] When starting detection, the rotating assembly 3 is driven to move in a circle inside the arc-shaped assembly 2, so that the rotating assembly 3 drives the detection assembly 4 to move around the outside of the conical fender 100. In the moving process, the size data of each point of the conical fender 100 is collected for fitting, so as to quickly measure and read the diameter size of the conical fender 100 at different positions. After each detection, the arc-shaped assembly 2 is driven to move along the axis of the conical fender 100, so that the arc-shaped assembly 2 drives the detection assembly 4 outside the rotating assembly 3 to conduct comprehensive diameter detection of the conical fender 100, instead of the traditional manual detection operation, which is high in working efficiency and standard in measurement.

[0025] On the basis of the above-mentioned embodiments, referring to Figures 5 to 7 The arc-shaped assembly 2 of the present scheme includes a fixed plate 24 fixedly connected with the detection frame 1, and the fixed plate 24 is a vertically arranged plate body. A horizontal slide rail 23 is fixedly arranged on the side of the fixed plate 24. In order to realize the circular motion of the rotating assembly 3 inside the arc-shaped assembly 2, the arc-shaped assembly 2 of the present scheme is further provided with a semicircular outer arc plate 21, and symmetrical slide sleeves 22 are fixedly arranged on the outside of the outer arc plate 21. The slide sleeves 22 are sleeved outside the slide rail 23 and are in sliding connection with the slide rail 23. Symmetrical main guide rails 25 are fixedly arranged on the inside of the outer arc plate 21, and the main guide rails 25 are composed of two symmetrical “L”-shaped arc plates, and a sliding channel in the shape of “” is formed inside the main guide rails 25. The rotating assembly 3 includes an inner arc plate 31 corresponding to the conical fender 100, and a connecting plate 32 is arranged on the outside of the inner arc plate 31. The connecting plate 32 corresponds to the sliding channel inside the main guide rail 25, and is in the shape of a “T”-shaped arc plate. The inner arc plate 31 is in sliding connection with the main guide rail 25 through the connecting plate 32, and the inner arc plate 31 is located on the side of the main guide rail 25 facing the conical fender 100. The detection assembly 4 is arranged on the inner arc plate 31.

[0026] Corresponding driving mechanisms are arranged corresponding to the outer arc plate 21, so that the outer arc plate 21 drives the inner arc plate 31 to move along the axis of the conical fender 100. Corresponding driving mechanisms are arranged corresponding to the inner arc plate 31, so that the rotation of the inner arc plate 31 can be realized. The structure of the main guide rail 25 and the connecting plate 32 can ensure the stability of the rotation of the inner arc plate 31, and is a basic condition for realizing accurate detection.

[0027] On the basis of the above-mentioned embodiments, referring to Figure 3 and Figure 6In order to realize the axial movement of the arc-shaped assembly 2 along the conical fender 100, two vertical plates 214 are symmetrically fixed on the outer side of the upper part of the outer arc plate 21, and the plate surface of the vertical plate 214 is parallel to the sliding direction of the slide rail 23. The inner side of the vertical plate 214 is provided with an inclined guide groove 215, and the one end of the guide groove 215 towards the fixed plate 24 is a low level end. A hydraulic cylinder A 220 is fixedly arranged on the detection frame 1, and the driving end of the hydraulic cylinder A 220 is fixedly provided with a sliding block B 218. A horizontal pressure rod 217 is arranged through the sliding block B 218, and the two ends of the pressure rod 217 are respectively fixedly provided with a sliding block A 216. The two sliding blocks A 216 are respectively and slidably connected with the guide grooves 215 in the vertical plates 214.

[0028] In order to ensure the stable movement of the driving end of the hydraulic cylinder A 220, a vertical guide rail 219 is further arranged on the side of the detection frame 1, and the sliding block B 218 is slidably connected with the vertical guide rail 219. When the inner arc plate 31 drives the detection assembly 4 to complete one cycle of detection, the sliding block B 218 is driven by the hydraulic cylinder A 220 to move downward along the vertical guide rail 219, and the sliding block B 218 drives the pressure rod 217 and the sliding blocks A 216 at both ends of the pressure rod 217 to synchronously move downward. By means of the sliding cooperation of the sliding blocks A 216 and the guide grooves 215, the vertical plate 214 is pushed to move axially along the conical fender 100, so as to drive the outer arc plate 21 to translate, thereby ensuring the stable sliding.

[0029] By means of the above structure, the slide rail 23 is used as the guide of the outer arc plate 21, and the translation is realized by means of the cooperation of the vertical plate 214 and the guide groove 215. Compared with directly using the hydraulic cylinder to apply the driving force in the horizontal direction, the movement distance of the outer arc plate 21 can be more accurately controlled.

[0030] On the basis of the above embodiment, referring to Figure 5 , Figure 6 and Figure 10In order to drive the rotation of the inner arc plate 31, an arc-shaped tooth plate 33 is fixedly arranged outside the connecting plate 32, and the central angle of the inner arc plate 31 is arranged to be equal to or slightly greater than 180°. A rotating shaft 26 is arranged at each of the two ends of the main guide rail 25, and the rotating shafts 26 are symmetrically arranged on the horizontal diameter of the arc-shaped assembly 2. A gear 27 is coaxially fixed outside each of the rotating shafts 26, and the gears 27 are engaged with the arc-shaped tooth plate 33. A toothed belt wheel A 28 is also coaxially fixed on the rotating shaft 26, and a toothed belt wheel B 29 is rotatably arranged outside the outer arc plate 21. The toothed belt wheel A 28 and the toothed belt wheel B 29 are connected through a toothed belt 210. A rotating shaft 211 is rotatably arranged inside the main guide rail 25 corresponding to the bottom of the toothed belt 210, and a guide wheel 212 is rotatably arranged for tensioning and guiding the toothed belt 210. A through groove is reserved on the outer arc plate 21 for the toothed belt 210 to engage with the toothed belt wheel B 29. A motor 213 is arranged corresponding to the toothed belt wheel B 29, and the toothed belt wheel B 29 is driven to rotate by the motor 213, so that the toothed belt 210, the toothed belt wheel A 28, the rotating shaft 26 and the gear 27 form a linkage structure, thereby achieving the driving of the inner arc plate 31.

[0031] In order to prevent the inner arc plate 31 from continuously rotating and causing the external connecting components (such as wire harness) of the detection assembly 4 to be wound, it is necessary to reciprocally rotate the inner arc plate 31 and the detection assembly 4 outside the conical fender 100. In order to achieve the sliding cooperation between the inner arc plate 31 and the main guide rail 25, it is better to make the corresponding central angle of the inner arc plate 31 slightly greater than 180°.

[0032] On the basis of the above-mentioned embodiments, in order to complete the outer diameter detection of the conical fender 100 during rotation and movement, referring to Figure 7 、 Figure 8 and Figure 11A through hole is formed on the inner arc plate 31, and a limiting sleeve 34 is fixedly arranged at the through hole. The detection assembly 4 comprises a detection cylinder 41 which is slidingly arranged inside the limiting sleeve 34 along the radial direction of the inner arc plate 31. The detection cylinder 41 is provided with a ball 42 at one end thereof which faces the conical fender 100. The limiting sleeve 34 penetrates through the inner arc plate 31, and a threaded structure is arranged at an end of the limiting sleeve 34 which is away from the conical fender 100, and a sleeve 43 is connected to the threaded structure in a threaded connection manner. The sleeve 43 is fixedly provided with a detection sensor 44 at an end thereof which is away from the conical fender 100, and the detection sensor 44 is used for detecting the moving distance of the detection cylinder 41. Specifically, the detection sensor 44 is a distance sensor. One end of the detection cylinder 41 which faces the detection sensor 44 is fixedly connected with a detection rod 46, the detection rod 46 is coaxial with the limiting sleeve 34, and the end of the detection rod 46 is aligned with the detection end of the detection sensor 44. A spring 45 is arranged outside the detection rod 46, and the spring is used for applying an elastic force to the detection cylinder 41. A limiting ring 47 is fixedly arranged at an end of the detection cylinder 41 which is away from the ball 42, and a contact is arranged on the detection rod 46 which corresponds to the limiting ring 47. The detection sensor 44 is electrically connected with a detection terminal through external wires 48, and a support 35 is fixedly arranged outside the inner arc plate 31 and is used for supporting and fixing the wires 48. The detection assembly 4 is symmetrically arranged at both ends of the inner arc plate 31, and is symmetrically arranged about the bisector of the inner arc plate 31, and four detection assemblies 4 are arranged in total. The distance between the two groups of detection assemblies 4 which are arranged in the axial direction is less than or equal to the length of the conical fender 100.

[0033] In the initial state, the detection cylinder 41 is pushed towards the conical fender 100 by the elastic force of the spring 45. When the rotating assembly 3 is fitted outside the conical fender 100, the detection cylinder 41 at the corresponding position is in rolling frictional contact with the conical fender 100 through the end ball 42 under the influence of the extrusion of the side wall of the conical fender 100. At this time, the detection cylinder 41 starts to extrude the spring 45, and the elastic force of the spring 45 can keep the ball 42 always located outside the conical fender 100. When the inner arc plate 31 is driven to rotate, the detection cylinder 41 moves along the surface of the conical fender 100 by the ball 42. During the movement, if the diameters at different positions change, the sliding distance of the detection cylinder 41 inside the limiting sleeve 34 will be different. At this time, the detection sensor 44 at the end of the sleeve 43 can detect the distance between the detection rod 46 in real time, and the diameter size corresponding to a position of the conical fender 100 can be indirectly detected according to the change amount of the moving distance of the detection rod 46. Not only the reading is fast and accurate, but also the diameter change position can be obtained. In order to prevent the inner arc plate 31 from continuously rotating to cause the wire 48 to be wound, the inner arc plate 31 is reversely rotated to reset after driving the detection cylinder 41 to rotate 180°, and the two detection cylinders 41 are arranged on the same diameter, so that the conical fender 100 can be detected after rotating 180°. In order to prevent the detection cylinder 41 from having many detection dead angles in the axial direction of the conical fender 100, the detection assembly 4 is arranged at the edge of the inner arc plate 31 on both sides, and the distance between the two detection assemblies 4 in the axial direction is equal to or less than the axial length of the conical fender 100, so that the two detection assemblies 4 can detect the two ends of the conical fender 100 after moving to the two ends of the conical fender 100. The limiting ring 47 and the contact are arranged to form a control loop for the motor 213. If the diameter of the conical fender 100 is locally convex to exceed the normal value due to deformation or external attachments, the contact of the detection rod 46 and the limiting ring 47 is contacted in the process of pushing the detection cylinder 41, and then the motor 213 stops working, so that the staff can check in time. The detection sensor 44 only needs to use related electrical equipment that can feedback the distance, such as a laser ranging component.

[0034] On the basis of the above-mentioned embodiments, referring to Figures 1 to 4 and Figure 9 , in order to facilitate the movement of the detection device, the mounting piece 12 is fixedly arranged on the upper part of the detection frame 1 and located above the anti-collision wall 200, which is used for connecting and assembling the driving device. The mounting piece 12 can be assembled with the driving device (such as a forklift, an excavator, a crane, etc.) to facilitate the movement detection by driving the driving device during detection.

[0035] Further, the detection frame 1 is provided with a pressure assembly 5 outside for applying pressure to the tapered fender 100, and the size change amount of the tapered fender 100 is detected by applying axial pressure to the tapered fender 100. The detection frame 1 further comprises a cross arm 13 and a support arm 14 for connecting the pressure assembly 5. The cross arm 13 and the support arm 14 are fixed support structures. The pressure assembly 5 comprises a heavy pressure arm 51, a support shaft 52 fixedly arranged near the middle of the heavy pressure arm 51, the heavy pressure arm 51 is rotatably connected to one end of the cross arm 13 through the support shaft 52, and a pressure plate 53 movably arranged at the lower end of the heavy pressure arm 51. The pressure plate 53 can be attached to the outside of the guard plate 101 at the end of the tapered fender 100. A hydraulic arm 54 is rotatably arranged at the upper end of the heavy pressure arm 51, and the outer side of the hydraulic arm 54 is connected to the upper end of the support arm 14. The side of the pressure plate 53 close to the guard plate 101 is provided with an anti-skid structure, and the anti-skid structure of the present scheme is a plurality of vertically distributed groove type anti-skid structures, and the extension direction of the groove itself is horizontal. A counterweight frame 55 is symmetrically fixedly arranged on the side of the pressure plate 53 away from the guard plate 101, a sliding groove 56 is formed in the inner side of the upper half of the counterweight frame 55, and a sliding block C57 is slidably arranged in the inner side of the sliding groove 56. The sliding block C57 is rotatably arranged at the lower end of the heavy pressure arm 51 through a connecting shaft 58. A plug hole 59 is formed on the side of the sliding groove 56 away from the pressure plate 53, and a plug plate 510 is inserted into the plug hole 59, and the plug plate 510 is an "L" shaped plate body. A hydraulic cylinder B511 is fixedly arranged on the outer side of the upper part of the counterweight frame 55, and the vertical end of the plug plate 510 is fixedly connected with the movable end of the hydraulic cylinder B511.

[0036] When the preliminary detection of the size of the tapered fender 100 is completed, the upper end of the heavy pressure arm 51 is pushed by the hydraulic arm 54 to rotate around the support shaft 52, so that the heavy pressure arm 51 pushes the pressure plate 53 at the lower end to apply pressure to the tapered fender 100. At this time, the detection frame 1 is attached to the outside of the crash wall, and under the limiting action of the crash wall on the detection frame 1, the hydraulic arm 54 can apply a large pushing force to the heavy pressure arm 51, and rely on the lever principle to apply a heavy load to the pressure plate 53. The pressure plate 53 applies pressure along the axial direction of the tapered fender 100, so that the tapered fender 100 is deformed (usually showing inflation in the middle) under a certain pressure, and then the arc-shaped assembly 2 and the rotating assembly 3 drive the detection assembly 4 to move axially and rotate respectively to detect the size of the tapered fender 100 under the condition of absorbing collision. At this time, the pushing force applied by one end of the hydraulic arm 54 is applied to the end of the tapered fender 100, and the reaction force generated by the other end is applied to the crash wall, so as to ensure the stability of the driving equipment at the top of the crash wall, and to meet the detection work of large load. It should be noted that when the pressure state detection is carried out, the detection control of the limiting ring 47 and the upper contact of the detection rod 46 is in the closed state.

[0037] Principle of tapered rubber fender detection equipment: First, the installation of the installation 12 and the driving device is installed, driven by the driving device, the positioning groove 11 at the bottom of the detection frame 1 is tangent to the bottom of the cone fender 100 outside the base, because the arc assembly 2 is coaxial with the incircle of the positioning groove 11, the arc assembly 2 can be aligned with the axis of the cone fender 100 after the positioning groove 11 is located outside the base of the cone fender 100, so as to facilitate the rapid expansion of the arc assembly 2, rotating assembly 3 and detection assembly 4 during detection with the axis of the cone fender 100 as the reference; in the initial state, the spring 45 is pushed to the inner arc plate 31 axis by the elastic force, when the rotating assembly 3 drives the detection cylinder 41 to cooperate from top to bottom outside the cone fender 100, the detection cylinder 41 at the corresponding position is in rolling friction contact with the cone fender 100 through the end ball 42, at this time the detection cylinder 41 starts to extrude the spring 45, and the ball 42 can be kept outside the cone fender 100 at all times by the elastic force of the spring 45; Then start the motor 213 to drive the toothed belt wheel B29 to rotate, make the toothed belt wheel B29 drive the two toothed belt wheels A28 between the main guide rails 25 to rotate synchronously and in the same direction through the toothed belt 210, drive the gear 27 to rotate synchronously through the toothed belt wheel A28 through the rotating shaft 26, and then cooperate with the arc toothed plate 33 to drive the inner arc plate 31 to slide between the main guide rails 25; the detection cylinder 41 moves along the surface of the cone fender 100 by the ball 42 under the drive of the inner arc plate 31, during the movement, if the diameters at different positions change, the sliding distance of the detection cylinder 41 inside the limiting sleeve 34 will be different, at this time the distance between the detection sensor 44 at the end of the sleeve 43 and the detection rod 46 can be detected in real time, the diameter size corresponding to a position of the cone fender 100 can be indirectly detected according to the change amount of the moving distance of the detection rod 46, not only the reading is fast and accurate, but also the diameter change position can be obtained; and in order to prevent the inner arc plate 31 from continuously rotating to cause the wire 48 to be wound, the inner arc plate 31 is reversely rotated to reset after driving the detection cylinder 41 to rotate 180°, and the two detection cylinders 41 are arranged on the same diameter, so that the cone fender 100 can be detected for one turn after rotating 180°; When the detection of the cone fender 100 for one turn is completed, the sliding block B218 is driven to move up and down along the vertical guide rail 219 by the hydraulic cylinder A220, the sliding block B218 drives the pressing rod 217 and the sliding blocks A216 at both ends thereof to move up and down, the sliding block A216 slides along the inside of the guide groove 215 when moving up and down, and then pushes the vertical plate 214 to move along the axial direction of the cone fender 100, so that the vertical plate 214 drives the outer arc plate 21 and the sliding sleeve 22 outside the outer arc plate 21 to slide along the slide rail 23, so as to ensure the sliding stability, and drives the rotating assembly 3 inside to move synchronously, so that the detection assembly 4 can comprehensively detect the cone fender 100.

[0038] The pressing assembly 5 in the conical rubber fender detection equipment of the application, when detecting, pushes the upper end of the heavy pressing arm 51 to rotate around the support shaft 52 through the hydraulic arm 54, so that the heavy pressing arm 51 pushes the pressing plate 53 at the lower end to apply pressure to the conical fender 100. At this time, the detection frame 1 is attached to the outside of the anti-collision wall. Under the limiting action of the anti-collision wall to the detection frame 1, the hydraulic arm 54 can apply a large pushing force to the heavy pressing arm 51, and rely on the lever principle to apply a heavy load to the pressing plate 53, so that the pressing plate 53 applies pressure along the axial direction of the conical fender 100, so that the conical fender 100 is deformed after being subjected to a certain pressure. Then, the arc-shaped assembly 2 and the rotating assembly 3 drive the detection assembly 4 to move axially and rotate, respectively, to detect the size of the conical fender 100 under the condition of absorbing the impact. At this time, the pushing force applied by one end of the hydraulic arm 54 is applied to the end of the conical fender 100, and the reaction force generated on the other end is applied to the anti-collision wall, so as to ensure the stability of the driving equipment at the top of the anti-collision wall, and to meet the detection work of large load.

[0039] When the heavy pressing arm 51 drives the pressing plate 53 to approach the outside of the fender 101 from top to bottom, the sliding block C57 is located at the bottom of the sliding groove 56 under the action of the top plug plate 510. At this time, the center of gravity of the counterweight frame 55 is located below the connecting shaft 58, and the pressing plate 53 is driven to be in a vertical state by relying on its own gravity. When the heavy pressing arm 51 pushes the pressing plate 53 to approach the fender 101, the pressing plate 53 is stably attached to the fender 101. When pressure needs to be applied to the conical fender 100, the plug plate 510 is driven to slide outward in the insertion hole 59 by the hydraulic cylinder B511, so that the plug plate 510 releases the limitation on the sliding block C57. Then, the upper end of the heavy pressing arm 51 is pushed by the hydraulic arm 54 to rotate around the support shaft 52. In the rotating process, the heavy pressing arm 51 drives the sliding block C57 at the lower end to slide upward in the sliding groove 56 through the connecting shaft 58. While sliding, the pressing plate 53 is pushed to apply pressure to the fender 101, and finally the pressure is transmitted to the end of the conical fender 100, so as to detect the change in diameter under the condition of applying pressure to the conical fender 100. After detection, the heavy pressing arm 51 is reset by the hydraulic arm 54, and the mounting member 12 is driven upward by the driving equipment at the top of the anti-collision wall, so that the mounting member 12 drives the arc-shaped assembly 2 and the pressing assembly 5 outside the detection frame 1 to move away from the outside of the conical fender 100, and the counterweight frame 55 is transferred to the top of the anti-collision wall. During this process, the center of gravity of the counterweight frame 55 is always located below the connecting shaft 58, so as to ensure that the counterweight frame 55 drives the pressing plate 53 to be vertically erected on the top of the anti-collision wall. Then, the mounting member 12 is lowered by a certain distance by the driving equipment, so that the sliding block C57 at the lower end of the heavy pressing arm 51 slides to the bottom of the sliding groove 56 again. Then, the plug plate 510 is inserted into the inside of the sliding groove 56 to limit the sliding block C57 by the hydraulic cylinder B511, so as to reset the sliding block C57. The detection work can be continued by moving to the next detection position of the conical fender 100 through the driving equipment.

[0040] It is worth mentioning that the above detection method has the following advantages: Advantage one, by setting the hydraulic arm 54 to push the upper end of the heavy pressure arm 51 to rotate around the support shaft 52 and using the lever principle, the effect of applying a large pressure to the conical fender 100 in a small space is realized, so that the detection equipment can meet the detection work demand of large load, and the accuracy and reliability of detection are improved.

[0041] Advantage two, rely on the gravity of the counterweight frame 55 to drive the pressing plate 53 to be in a vertical state, when the heavy pressure arm 51 pushes the pressing plate 53 to the guard plate 101, it can ensure that the pressing plate 53 and the guard plate 101 are stably attached, avoiding detection errors caused by unstable contact, and improving the detection accuracy.

[0042] Advantage three, by driving the plug plate 510 to slide in the plug hole 59 to release the limit of the sliding block C57, and then realize the hydraulic arm 54 to the heavy pressure arm 51 to apply a pushing force to push the pressing plate 53 to the guard plate 101 to apply a pressure, this structure design makes the operation more flexible and convenient, and can accurately control the size and direction of the applied pressure according to the detection requirement.

[0043] Advantage four, after detection, through a series of operations, the counterweight frame 55 is transferred to the top of the crash wall and the center of gravity is always located below the connecting shaft 58, so that the counterweight frame 55 drives the pressing plate 53 to be vertically erected on the top of the crash wall, which is convenient for subsequent operation of the sliding block C57 reset, improves the reset efficiency and stability of the detection equipment, and prepares for the next detection.

[0044] Advantage five, the detection equipment can be moved to the next conical fender 100 detection position by driving equipment to continue detection work, realizes the continuity and efficiency of detection, greatly shortens the overall detection time, improves the detection efficiency, and can meet the demand of large-scale detection.
