Description

Technical Field

[0001] This invention relates to the field of fender testing technology, specifically to a conical rubber fender testing device and testing method. Background Technology

[0002] Conical rubber fenders are crucial protective devices for port and dock facilities, serving as buffers, collision avoidance, and protection when ships berth. Their performance directly impacts the safety and lifespan of port facilities. With the rapid development of the shipping industry and the continuous increase in ship tonnage, the performance requirements for fender systems are also rising. Regular inspections can promptly detect problems such as rubber aging and structural damage, preventing ship collisions caused by fender failure. Furthermore, standardized inspections can extend the service life of fenders and reduce port operating costs.

[0003] In related technologies, according to testing technical standards and specifications (such as GB / T 21537-2008 "Conical Rubber Fenders", JT / T 4-2019 "Rubber Fenders for Port Engineering", ASTM D2000 Rubber Material Standard, etc.), the testing of conical rubber fenders mainly includes the following items: 1. Visual inspection: surface cracks, wear, deformation, etc.; 2. Dimensional measurement: key dimensions such as height, diameter, and taper; 3. Physical performance testing: hardness, tensile strength, elongation, etc.; 4. Aging performance evaluation; 5. Internal structure inspection: whether there are defects such as delamination and bubbles; 6. Connector inspection: corrosion of metal parts such as bolts and anchors.

[0004] In actual testing, the principle of "exterior first, interior second; overall first, parts second" should be followed. When inspecting the dimensions of the conical rubber fender, manual operation with conventional measuring tools such as tape measures is required. Due to the large actual volume of the conical rubber fender, this inspection process is cumbersome and labor-intensive. Moreover, inaccurate readings directly affect the inspection results of the conical rubber fender (according to the evaluation criteria for inspection results, the dimensional deviation is: height deviation not exceeding ±2%, diameter deviation not exceeding ±1.5%). Summary of the Invention

[0005] To address one of the shortcomings of existing technologies, this invention provides a tapered rubber fender inspection device and method, which solves the problems of cumbersome operation and inaccurate readings when manually inspecting dimensions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conical rubber fender testing device, comprising:

[0054] Compared with existing technologies, this solution offers the following advantages: The use of a testing frame and arc-shaped components allows the testing components to quickly deploy around the axis of the conical fender during testing, significantly improving testing efficiency. During testing, a rotating component is driven to move in a circular motion inside the arc-shaped component, causing the testing component to move around the outer side of the conical fender. During this movement, dimensional data at each point on the conical fender is collected and fitted to quickly measure and read the diameter at different locations, replacing traditional manual testing. This results in higher work efficiency and more standardized measurements.

[0055] In addition, this solution is equipped with a pressurization component, which can apply pressure to the axial end of the conical fender to simulate its state when it is squeezed. After the normal test is completed, the deformation state during the squeeze can be tested again. Attached Figure Description

[0074] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0075] Please see Figures 1 to 4 This application provides the following technical solutions:

[0076] The conical rubber fender inspection equipment includes an inspection frame 1, an arc-shaped component 2, a rotating component 3, and an inspection component 4. The inspection frame 1 is connected to an external support device and is transported by the external device to the required location, namely the crash barrier 200 where the conical fender 100 to be inspected is located. The external device pushes the inspection frame 1 from top to bottom onto the conical fender 100 to be inspected, ensuring it is in contact with the side of the crash barrier 200 where the conical fender 100 is located. The arc-shaped component 2 is connected to the inspection frame 1 and is also designed to slide horizontally. The arc-shaped component 2 serves as a support structure for the rotating component 3 and also drives the rotating component 3 to move axially along the conical fender 100. The rotating component 3 is slidably connected to the arc-shaped component 2 and is located inside the arc-shaped component 2. The rotating component 3 performs a reciprocating circular motion on the radial circumference of the conical fender 100. The rotating component 3 serves as a support structure for the inspection component 4, and the inspection component 4 is mounted on the rotating component 3. The detection end of the detection component 4 extends towards the inner side of the rotating component 3, which is the side where the conical fender 100 is located. The central angle of the detection component 2 can be equal to or slightly greater than 180°. In addition, a rectangular positioning groove 11 is provided at the lower part of the detection frame 1. The lower port of the positioning groove 11 is an open port, 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 positioning groove 11 is coaxially set with the arc component 2. By using the center determined by the positioning groove 11, the arc component 2 and the inscribed circle of the positioning groove 11 are coaxially set, thereby facilitating the positioning of the arc component 2 and the conical fender 100.

[0077] Conical fenders 100 are typically installed on the outside of the dock's crash barrier, thus forming... Figure 1 The assembly configuration is shown. The conical fender 100 directly bears the impact force of the ship, serving as a buffer structure when the hull and the crash barrier 200 come into contact. During the inspection of the conical fender 100, an external drive device, such as a corresponding transport vehicle or transport frame, drives the inspection frame 1 to move from top to bottom along the side of the crash barrier 200. This causes the inspection frame 1 to move the arc-shaped component 2 to the upper side of the conical fender 100 and to abut against the outer wall of the crash barrier. With the help of the positioning groove 11 of the inspection frame 1, the arc-shaped component 2 and the conical fender 100 are coaxially aligned, thereby positioning the rotating component 3 and the inspection component 4 for subsequent inspection work.

[0078] When starting the detection, the rotation component 3 is driven to move in a circular motion inside the arc component 2, so that the rotation component 3 drives the detection component 4 to move around the outer side of the fender 100. During the movement, the dimensional data of each point of the fender 100 is collected for fitting, so as to quickly measure and read the diameter dimensions of different positions of the fender 100; and after each detection cycle, by driving the arc component 2 to move along the axial direction of the fender 100, the arc component 2 can be made to drive the detection component 4 outside the rotation component 3 to perform a comprehensive diameter detection of the fender 100, replacing the traditional manual detection operation, with high work efficiency and more standard readings.

[0079] Based on the above implementation, see Figures 5 to 7 In this solution, the arc component 2 includes a fixed plate 24 fixedly connected to the detection frame 1. The fixed plate 24 is a vertically arranged plate body. A horizontal slide rail 23 is fixedly arranged on the side surface of the fixed plate 24. In order to enable the rotation component 3 to move in a circular motion inside the arc component 2, the arc component 2 of this solution is further provided with a semi-circular outer arc plate 21. Symmetrically fixed on the outer side of the outer arc plate 21 are sliding sleeves 22. The sliding sleeves 22 are sleeved outside the slide rail 23 and are slidably connected to the slide rail 23. Symmetrically fixed on the inner side of the outer arc plate 21 are main guide rails 25. The main guide rails 25 are composed of two symmetrically arranged "L"-shaped arc plates, and a "convex"-shaped sliding channel is formed inside. The rotation component 3 includes an inner arc plate 31. The inner arc plate 31 corresponds to the fender 100. A connecting plate 32 is arranged on its outer side. The connecting plate 32 corresponds to the sliding channel inside the main guide rail 25 and is a "T"-shaped arc plate structure. The inner arc plate 31 is slidably connected to 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 fender 100. The detection component 4 is arranged on the inner arc plate 31.

[0080] By setting a corresponding driving mechanism for the outer arc plate 21, the outer arc plate 21 can be driven to带动 the inner arc plate 31 to move along the axial direction of the fender 100. And by setting a corresponding driving mechanism for the inner arc plate 31, the rotation of the inner arc plate 31 can be实现. The structure form of the cooperation of the main guide rail 25 and the connecting plate 32 can ensure the stability of the rotation of the inner arc plate 31, which is the basic condition for achieving precise detection.

[0081] Based on the above implementation, see Figure 3 and Figure 6To enable the drive arc-shaped component 2 to move axially 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. The surface of the vertical plates 214 is parallel to the sliding direction of the slide rail 23. Inclined guide grooves 215 are provided on the inner side of each vertical plate 214, with the end of the guide groove 215 facing the fixed plate 24 being the low horizontal end. A hydraulic cylinder A220 is fixedly mounted on the detection frame 1, and a slider B218 is fixedly mounted on the driving end of the hydraulic cylinder A220. A horizontal pressure rod 217 is provided through the slider B218, and a slider A216 is fixedly mounted at each end of the pressure rod 217. The two sliders A216 are slidably connected to the guide groove 215 in one of the vertical plates 214.

[0082] To ensure stable movement at the drive end of the hydraulic cylinder A220, a vertical guide rail 219 is provided on the side of the inspection frame 1, with the slider B218 slidably connected to the vertical guide rail 219. After the inner arc plate 31 drives the inspection assembly 4 to complete one revolution of inspection, the hydraulic cylinder A220 drives the slider B218 to move downward along the vertical guide rail 219. The slider B218 drives the pressure rod 217 and the sliders A216 at both ends to move downward synchronously. With the sliding cooperation between the slider A216 and the guide groove 215, the vertical plate 214 is pushed to move axially along the conical fender 100, thereby driving the outer arc plate 21 to translate, thus ensuring sliding stability.

[0083] With this structure, the slide rail 23 serves as the guide for the outer arc plate 21, and translation is achieved by the cooperation of the vertical plate 214 and the guide groove 215. Compared with directly applying horizontal driving force using a hydraulic cylinder, this form can more accurately control the moving distance of the outer arc plate 21.

[0084] Based on the above implementation plan, see Figure 5 , Figure 6 and Figure 10To drive the rotation of the inner arc plate 31, an arc-shaped toothed plate 33 is fixedly installed on the outer side of the connecting plate 32. The central angle of the inner arc plate 31 is set to be equal to or slightly greater than 180°. A rotating shaft 26 is installed at each end of the main guide rail 25. The rotating shafts 26 are symmetrically arranged on the horizontal diameter of the arc component 2. Gears 27 are coaxially fixedly installed on the outer side of each rotating shaft 26, and the gears 27 mesh with the arc-shaped toothed plate 33. A toothed pulley A28 is also coaxially fixedly installed on the rotating shaft 26. A toothed pulley B29 is rotatably installed on the outer side of the outer arc plate 21. The two toothed pulleys A28 and B29 are linked by a toothed belt 210. A rotating shaft 211 is rotatably installed on the inner side of the main guide rail 25 corresponding to the bottom of the toothed belt 210, and a guide wheel 212 for tensioning and guiding the toothed belt 210 is rotatably installed. The outer arc plate 21 has a pre-drilled groove for a toothed belt 210 to mesh with a toothed pulley B29. A motor 213 is provided corresponding to the toothed pulley B29. The motor 213 drives the toothed pulley B29 to rotate, thereby making the toothed belt 210, toothed pulley A28, rotating shaft 26 and gear 27 form a linkage structure, thus driving the inner arc plate 31.

[0085] To prevent the inner arc plate 31 from continuously rotating and causing the external connecting parts (such as wire harnesses) of the detection component 4 to become entangled, the inner arc plate 31 needs to drive the detection component 4 to reciprocate on the outside of the conical fender 100. In order to achieve a constant sliding fit between the inner arc plate 31 and the main guide rail 25, it is best to make the central angle corresponding to the inner arc plate 31 slightly greater than 180°.

[0086] Based on the above implementation plan, in order to complete the outer diameter inspection of the conical fender 100 during rotation and movement, see [link to relevant documentation]. Figure 7 , Figure 8 and Figure 11A through hole is provided on the inner arc plate 31, and a limiting sleeve 34 is fixedly installed at the through hole. The detection assembly 4 includes a detection cylinder 41, which is slidably disposed inside the limiting sleeve 34 along the radial direction of the inner arc plate 31. A ball bearing 42 is provided at the end of the detection cylinder 41 facing the conical fender 100. The limiting sleeve 34 passes through the inner arc plate 31, and its end away from the conical fender 100 is provided with a threaded structure, which is connected to a sleeve 43 by a threaded connection. A detection sensor 44 for detecting the moving distance of the detection cylinder 41 is fixedly installed at the end of the sleeve 43 away from the conical fender 100. Specifically, the detection sensor 44 is a distance sensor. A detection rod 46 is fixedly connected to the end of the detection cylinder 41 facing the detection sensor 44. The detection rod 46 and the limiting sleeve 34 are coaxial, and the end of the detection rod 46 is aligned with the detection end of the detection sensor 44. A spring 45 is sleeved on the outside of the detection rod 46, and the spring is used to apply elastic force to the detection cylinder 41. A limiting ring 47 is fixedly installed at the end of the detection cylinder 41 away from the ball bearing 42, and a contact point is set on the detection rod 46 corresponding to the limiting ring 47. The detection sensor 44 is electrically connected to the detection terminal through an external wire 48; a bracket 35 for supporting and fixing the wire 48 is fixedly installed on the outer side of the inner arc plate 31. The detection components 4 are symmetrically arranged at both ends of the inner arc plate 31 and symmetrically arranged about the bisector of the inner arc plate 31, with a total of four components. The distance between two sets of detection components 4 located in the axial direction is less than or equal to the length of the conical fender 100.

[0087] 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 component 3 is engaged with the outside of the conical fender 100, it is affected by the pressure of the side wall of the conical fender 100. The detection cylinder 41 at the corresponding position makes rolling friction contact with the conical fender 100 through the end ball 42. At this time, the detection cylinder 41 begins to compress the spring 45. The elastic force of the spring 45 can keep the ball 42 always located on the outside of the conical fender 100. And when the inner arc plate 31 rotates, the detection cylinder 41 moves circumferentially along the surface of the conical fender 100 by the ball 42. During the movement, if the diameter changes at different positions, 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 cylinder 41 and the detection rod 46 in real time. According to the detection rod 46 The change in the moving distance is used to indirectly detect the diameter of a certain position on the conical fender 100. This not only provides fast and accurate readings but also reveals the location of the diameter change. Furthermore, to prevent the continuous rotation of the inner arc plate 31 from entangled with the wire 48, the inner arc plate 31 rotates in the opposite direction to reset after each 180° rotation of the detection cylinder 41. The two detection cylinders 41 are positioned on the same diameter, allowing for a complete rotation of the conical fender 100 after each 180° rotation. To prevent excessive blind spots along the axial direction of the conical fender 100, the detection components 4 are positioned at the edges on both sides of the inner arc plate 31. The distance between the two sets of detection components 4 in the axial direction is equal to or less than the axial length of the conical fender 100, allowing the two sets of detection components 4 to detect both ends of the conical fender 100 after moving to their respective ends. The setting of the limit ring 47 and contacts forms the control circuit for the motor 213. If the conical fender 100 bulges outward beyond its normal diameter due to deformation or external attachments, the detection cylinder 41 will cause the contact point of the detection rod 46 to engage with the limiting ring 47 during the pushing process, and then the motor 213 will stop working, allowing personnel to conduct timely inspections. The detection sensor 44 only needs to use relevant electrical equipment capable of providing distance feedback, such as laser rangefinders.

[0088] Based on the above implementation plan, see Figures 1 to 4 and Figure 9 To facilitate the movement and use of the testing equipment, a mounting component 12 is fixedly installed on the upper part of the testing frame 1. The mounting component 12 is located above the crash barrier 200 and is used to connect and assemble the drive equipment. By assembling the mounting component 12 with the drive equipment (such as a forklift, excavator, crane, etc.), it is convenient to drive the drive equipment for mobile testing.

[0089] In addition, a pressurizing assembly 5 is provided on the outer side of the testing frame 1 for applying pressure to the conical fender 100. The dimensional change of the conical fender 100 is detected by applying axial pressure to it. The connecting frame 1 also includes a horizontal arm 13 and a support arm 14 for connecting with the pressurizing assembly 5. Both the horizontal arm 13 and the support arm 14 are fixed support structures. The pressurizing assembly 5 includes a heavy-duty arm 51, and a support shaft 52 is fixedly installed near the middle of the heavy-duty arm 51. The outer side of the heavy-duty arm 51 is rotatably connected to one end of the horizontal arm 13 through the support shaft 52. A pressure plate 53 is movably installed at the lower end of the heavy-duty arm 51. The pressure plate 53 can fit against the outer side of the guard plate 101 at the end of the conical fender 100. A hydraulic arm 54 is rotatably installed at the upper end of the heavy-duty arm 51, and the outer side of the hydraulic arm 54 is connected to the upper end of the support arm 14. An anti-slip structure is provided on the side of the pressure plate 53 near the guard plate 101. This anti-slip structure consists of several vertically distributed grooves, with the grooves extending horizontally. A counterweight frame 55 is symmetrically fixed on the side of the pressure plate 53 away from the guard plate 101. A groove 56 is formed on the inner side of the upper half of the counterweight frame 55, and a slider C57 is slidably mounted inside each groove 56. Each slider C57 is rotatably mounted on the lower end of the heavy-duty arm 51 via a connecting shaft 58. An insertion hole 59 is formed on the side of the groove 56 away from the pressure plate 53, and an insertion plate 510 is inserted into the inner side of the insertion hole 59. The insertion plate 510 is an "L"-shaped plate. A hydraulic cylinder B511 is fixedly mounted on the upper outer side of the counterweight frame 55, and the vertical end of the insertion plate 510 is fixedly connected to the movable end of the hydraulic cylinder B511.

[0090] After the preliminary dimensional inspection of the conical fender 100 is completed, the upper end of the heavy-duty arm 51 is rotated around the support shaft 52 by the hydraulic arm 54, so that the heavy-duty arm 51 pushes the pressure plate 53 at the lower end to apply pressure to the conical fender 100. At this time, the inspection frame 1 is attached to the outside of the crash barrier. Under the limiting effect of the crash barrier on the inspection frame 1, the hydraulic arm 54 can apply a large thrust to the heavy-duty arm 51, and apply a heavy load to the pressure plate 53 by lever principle. The pressure plate 53 applies pressure along the axial direction of the conical fender 100, so that the conical fender 100 deforms after being subjected to a certain pressure (usually manifested as expansion in the middle). Then, the arc-shaped component 2 and the rotating component 3 drive the inspection component 4 to move and rotate axially to perform dimensional inspection work on the conical fender 100 under the condition of absorbing the collision. At this time, the thrust 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 crash barrier to ensure the stability of the driving equipment at the top of the crash barrier and meet the inspection work of large load. It should be noted that during the pressure state detection, the detection control of the contacts on the limit ring 47 and the detection rod 46 is in the closed state.

[0091] The principle of the conical rubber fender testing equipment:

[0092] First, after installing the mounting component 12 and the drive device, the positioning groove 11 at the bottom of the testing frame 1 is tangentially positioned on the outside of the base of the conical fender 100 under the drive device. Since the arc-shaped component 2 and the inscribed circle of the positioning groove 11 are coaxially arranged, the arc-shaped component 2 can automatically align with the axis of the conical fender 100 after the positioning groove 11 is located on the outside of the base of the conical fender 100. This facilitates the rapid unfolding of the arc-shaped component 2, the rotating component 3, and the testing component 4 with the axis of the conical fender 100 as the reference during testing. Testing operation; In the initial state, the detection cylinder 41 is pushed closer to the axis of the inner arc plate 31 by the elastic force of the spring 45. When the rotating component 3 drives the detection cylinder 41 to cooperate with the outer side of the conical fender 100 from top to bottom, it is affected by the pressure of the side wall of the conical fender 100. The detection cylinder 41 at the corresponding position makes rolling friction contact with the conical fender 100 through the end ball 42. At this time, the detection cylinder 41 begins to squeeze the spring 45. The elastic force of the spring 45 can keep the ball 42 always located on the outer side of the conical fender 100.

[0093] Then, the motor 213 is started to drive the toothed pulley B29 to rotate, so that the toothed pulley B29 drives the two toothed pulleys A28 between the main guide rails 25 to rotate synchronously and in the same direction through the toothed belt 210. The toothed pulleys A28 drive the gear 27 to rotate synchronously through the rotating shaft 26, which in turn drives the inner arc plate 31 to slide between the main guide rails 25 in conjunction with the arc toothed plate 33. The detection cylinder 41 moves circumferentially along the surface of the conical fender 100 by the ball bearings 42 under the drive of the inner arc plate 31. If the diameter changes at different positions during the movement, the detection cylinder 41 slides inside the limiting sleeve 34. At different distances, the detection sensor 44 at the end of the sleeve 43 can detect the distance between it and the detection rod 46 in real time. The diameter of the conical fender 100 at a certain position can be indirectly detected based on the change in the movement distance of the detection rod 46. This not only provides fast and accurate readings but also reveals the position of diameter change. Furthermore, to prevent the inner arc plate 31 from tangling with the wire 48 due to continuous rotation, the inner arc plate 31 rotates in the opposite direction to reset after each 180° rotation of the detection cylinder 41. The two detection cylinders 41 are set on the same diameter, allowing for a full rotation of the conical fender 100 after 180° of rotation.

[0094] After a full rotation of the conical fender 100, the hydraulic cylinder A220 drives the slider B218 to move up and down along the vertical guide rail 219. This causes the slider B218 to move up and down the pressure rod 217 and the sliders A216 at both ends. When the sliders A216 move up and down, they slide along the inner side of the guide groove 215, which in turn pushes the vertical plate 214 to move along the axial direction of the conical fender 100. This causes the vertical plate 214 to move along the outer arc plate 21 and the outer sliding sleeve 22 along the slide rail 23 to ensure sliding stability. It also drives the internal rotating component 3 to move synchronously, so that the detection component 4 can perform a comprehensive inspection of the conical fender 100.

[0095] In the testing equipment for conical rubber fenders of this application, the pressurizing component 5 pushes the upper end of the heavy-duty arm 51 to rotate around the support shaft 52 via the hydraulic arm 54, causing the heavy-duty arm 51 to push the lower end of the pressure plate 53 to apply pressure to the conical fender 100. At this time, the testing frame 1 is attached to the outside of the crash barrier. Under the limiting effect of the crash barrier on the testing frame 1, the hydraulic arm 54 can apply a large thrust to the heavy-duty arm 51, and apply a heavy load to the pressure plate 53 by relying on the lever principle, so that the pressure plate 53 applies pressure along the axial direction of the conical fender 100, causing the conical fender 100 to deform after being subjected to a certain pressure. Then, the arc component 2 and the rotating component 3 drive the testing component 4 to move and rotate axially to perform dimensional testing work on the conical fender 100 under the condition of absorbing collision. At this time, the thrust 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 crash barrier to ensure the stability of the driving equipment at the top of the crash barrier and meet the testing work of large load.

[0096] When the heavy-duty arm 51 drives the pressure plate 53 to move from top to bottom towards the outside of the guard plate 101, the slider C57 is located at the bottom of the slide groove 56 under the action of the top insert plate 510. At this time, the center of gravity of the counterweight frame 55 is located below the connecting shaft 58, and the pressure plate 53 is in a vertical state by its own weight. When the heavy-duty arm 51 pushes the pressure plate 53 towards the guard plate 101, it facilitates the stable contact between the pressure plate 53 and the guard plate 101. When pressure needs to be applied to the conical fender 100, it is done through the hydraulic cylinder B. 511 drives the insert plate 510 to slide outward inside the insertion hole 59, releasing the insert plate 510 from limiting the slider C57. Then, the hydraulic arm 54 applies a thrust to the upper end of the heavy-duty arm 51, causing it to rotate around the support shaft 52. During the rotation, the heavy-duty arm 51 drives the lower slider C57 to slide upward inside the groove 56 via the connecting shaft 58. While sliding, it pushes the pressure plate 53 to apply pressure to the guard plate 101, which is finally transmitted to the end of the conical fender 100 to facilitate the conical... The diameter change of the conical fender 100 is detected under pressure. After detection, the hydraulic arm 54 drives the heavy pressure arm 51 to reset, and the drive device on the top of the crash barrier drives the mounting part 12 to move upward, so that the mounting part 12 drives the arc-shaped component 2 and the pressure component 5 on the outside of the detection frame 1 away from the outside of the conical fender 100, and transfers the counterweight frame 55 to the top of the crash barrier. During this process, the center of gravity of the counterweight frame 55 is always located below the connecting shaft 58 to ensure that the counterweight frame 55 drives the pressure plate 53 to stand vertically on the top of the crash barrier. Then, the drive device controls the mounting part 12 to descend a certain distance, so that the slider C57 at the lower end of the heavy pressure arm 51 slides to the bottom of the slide groove 56 again. Then, the hydraulic cylinder B511 drives the insert plate 510 to insert into the interior of the slide groove 56 to limit the slider C57, so as to facilitate the operation and reset of the slider C57. The drive device can then move to the next detection position of the conical fender 100 to continue the detection work.

[0097] It is worth noting that the above detection methods have the following advantages:

[0098] One advantage is that by setting up a hydraulic arm 54 to push the upper end of the heavy-duty arm 51 to rotate around the support shaft 52 and using the lever principle, a large pressure is applied to the conical fender 100 in a small space, which enables the testing equipment to meet the testing requirements of large loads and improves the accuracy and reliability of the testing.

[0099] Secondly, the counterweight frame 55 relies on its own weight to keep the pressure plate 53 in a vertical position. When the heavy pressure arm 51 pushes the pressure plate 53 closer to the guard plate 101, it can ensure that the pressure plate 53 and the guard plate 101 are stably attached, avoiding detection errors caused by unstable contact and improving the accuracy of detection.

[0100] Thirdly, the hydraulic cylinder B511 drives the insert plate 510 to slide inside the insert hole 59 to release the limit on the slider C57, thereby enabling the hydraulic arm 54 to apply a thrust to the heavy pressure arm 51 and push the pressure plate 53 to apply pressure to the guard plate 101. This structural design makes the operation more flexible and convenient, and can accurately control the magnitude and direction of the applied pressure according to the detection requirements.

[0101] Fourthly, after the test, a series of operations are performed to move the counterweight frame 55 to the top of the crash barrier and ensure that its center of gravity is always below the connecting shaft 58. This allows the counterweight frame 55 to drive the pressure plate 53 to stand vertically on the top of the crash barrier, which facilitates the subsequent operation and reset of the slider C57. This improves the reset efficiency and stability of the testing equipment and prepares it for the next test.

[0102] Fifthly, the testing equipment can be moved to the next conical fender 100 testing position by the drive device to continue the testing work, realizing the continuity and efficiency of the testing, greatly shortening the overall testing time, improving the testing efficiency, and meeting the needs of large-scale testing.
