Description

Technical Field

[0001] The invention relates to the technical field of lifting belt preparation, and in particular to a detection device and method for a high-strength polyester fiber lifting belt. Background Art

[0002] Conventional lifting belts are generally made of high-strength polyester fibers, which have multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, they are soft, light, non-conductive, and non-corrosive. They are widely used in various fields and have gradually replaced wire ropes in many aspects. The disadvantages of lifting belts are mainly different from wire ropes. The main manifestation is that when the hoisted objects have sharp edges, these sharp edges will cause destructive cuts to the lifting belts. Therefore, on the production line of lifting belts, the mechanical properties of the lifting belts need to be tested.

[0003] For example, a binding lifting belt strength testing device and a binding lifting belt production line with Chinese patent publication number CN117470664B include: a base, on which a symmetrically arranged fixed plate is fixed, and a cross plate is fixed on the fixed plate; a hollow rod, symmetrically arranged on the fixed plate, on which a locking mechanism connected to the hollow rod is arranged, and on the cross plate, a reverse synchronization component connected to the locking mechanism and the hollow rod is arranged, the locking mechanism can drive one of the hollow rods to move, and drive the other hollow rod to move in the opposite direction through the reverse synchronization component; an elastic support component, which is arranged on the fixed plate and connected to the hollow rod, and an arc block is connected to the elastic support component; a pressing mechanism, which is arranged on the fixed plate and connected to the hollow rod; a tensile testing mechanism, which is arranged on the fixed plate and connected to the hollow rod and the elastic support component.

[0004] The advantage of this solution is that, compared with the traditional tensile testing device, it can simulate the way the lifting belt is subjected to multiple force points during the lifting process, thereby improving the reliability of the experimental results. However, since the number of arc blocks used to fix the lifting belt and apply the pulling force is fixed, this solution is not convenient for adjusting the number of force points of the lifting belt. In the actual lifting process, the number of force points of the lifting belt varies depending on the shape of the lifting weight. Therefore, it is not convenient to further improve the accuracy of the test results, which needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide a detection device and method for a high-strength polyester fiber lifting belt, which can not only simulate the force mode of the lifting belt during the actual lifting process when detecting the mechanical properties of the lifting belt, but also adjust the number of force points to further improve the accuracy and reliability of the detection results.

[0019] 2. When reducing the stress point of the lifting belt body, the two push blocks contact each other and slide into the telescopic rod, pushing the square shell to rotate and compressing the reset spring. At this time, as the square shell rotates, the two support heads away from the square shell contact each other, thereby reducing the contact area with the lifting belt body and ensuring that the stress point of the lifting belt body is concentrated. In addition, one end of the support head is a conical structure, and the other end of the support head is an arc structure. By adjusting the shape of the contact position between the support head and the lifting belt body, the anti-cutting performance of the lifting belt body can be further tested.

[0044] like Figures 1 to 13 As shown:

[0045] A detection device for a high-strength polyester fiber lifting belt, comprising a raft 1, a base 10 and a frame 11. The top of the raft 1 is fixedly connected to the bottom of the base 10, and the bottom of the frame 11 is fixedly connected to the top of the base 10. The raft 1 is used to support the main body of the preparation device and the anti-swing component 5. The base 10 and the frame 11 are used to support the pulling component 2 and the supporting component 3. It also includes a pulling component 2, a supporting component 3 and a pair of anti-swing components 5. The pulling component 2 is installed on the top of the frame 11. The pulling component 2 is used to pull the two ends of the lifting belt body 12 upward. The anti-swing component 5 is installed on the raft 1. The anti-swing component 5 is used to prevent the lifting belt body 12 from being thrown out. The supporting component 3 includes a shell 30, a fixed column 31, a plurality of hydraulic cylinders 32 and a plurality of support rods 4. One side of the shell 30 is fixedly connected to the base 10, the fixed column 31 is fixedly connected to the inner wall of the shell 30, one end of the hydraulic cylinder 32 is fixedly connected to the fixed column 31, and the plurality of support rods 4 are arranged circumferentially on the periphery of the shell 30. The support rods 4 penetrate The hydraulic cylinder 32 passes through the side wall of the shell 30 and is slidably connected therewith. Each group of support rods 4 includes a sliding frame 40, a pair of telescopic rods 41, a pair of torsion springs 42, a pair of square shells 43 and a pair of support heads 44. The telescopic end of the hydraulic cylinder 32 is fixedly connected to the sliding frame 40, one end of the telescopic rod 41 is rotatably connected to the outer periphery of the sliding frame 40, the torsion spring 42 is sleeved on the outer periphery of the sliding frame 40, and the two ends of the torsion spring 42 are respectively fixedly connected to the two telescopic rods 41, the two telescopic rods 41 fit each other, the outer periphery of the telescopic rod 41 contacts each other with the shell 30, the square shell 43 is rotatably connected to the other end of the telescopic rod 41, and the support head 44 can be slidably installed in the square shell 43. When testing the strength of the lifting belt body 12, the lifting belt body 12 is sleeved on the outer periphery of the shell 30, and its inner wall is in contact with the support heads 44 on the multiple groups of support rods 4, and the two ends of the lifting belt body 12 are pulled upward at the same time by the pulling component 2. At this time, the lifting belt body 12 is subjected to the upward pulling force and the resistance force of the support rods 4 at the same time, so that it itself is torn by the pulling force, so that the strength of the lifting belt body 12 when subjected to multiple points of force can be tested. The hydraulic cylinder 32 is made to work to push the support rod 4 to slide out of the shell 30. As the support rod 4 moves away from the fixed column 31, the ends of the two telescopic rods 41 away from the shell 30 are pushed away from each other and opened by the torsion spring 42, so that the two support heads 44 are separated from each other, which can increase the number of stress points of the lifting belt body 12. The hydraulic cylinder 32 is made to work in the reverse direction, and the two telescopic rods 41 are squeezed by the shell 30 to move closer to each other, and the torsion spring 42 is compressed. At the same time, the two square shells 43 are rotated at a certain angle, so that the two support heads 44 are fitted together, which can reduce the number of stress points of the lifting belt body 12, thereby achieving the effect of adjusting the number of stress points of the lifting belt body 12, and can further improve the accuracy of the detection results.

[0046] like Figures 1 to 7 As shown:

[0047] The telescopic rod 41 includes a sleeve 410, a slide bar 411 and a hydraulic rod 412. One end of the sleeve is rotatably connected to the outer periphery of the sliding frame 40. One end of the slide bar 411 passes through the side wall of the sleeve and is slidably connected thereto. One end of the square shell 43 passes through the other end of the slide bar 411 and is rotatably connected thereto. One end of the hydraulic rod 412 is fixedly connected to the inner wall of the sleeve 410. The telescopic end of the hydraulic rod 412 is fixedly connected to the slide bar 411. When the hydraulic rod 412 is operated and the slide bar 411 is pushed out of the sleeve 410, the length of the telescopic rod 41 can be extended, thereby adapting to the hoisting belt body 12 of different lengths.

[0048] like Figures 1 to 7 As shown:

[0049] The support rod 4 also includes a pair of push blocks 45 and a pair of return springs 46. The two push blocks 45 pass through the side walls of the two slide bars 411 and are slidably connected thereto. The opposite ends of the two push blocks 45 contact each other. The opposite ends of the two push blocks 45 contact each other with one end of the two square shells 43. One end of the return spring 46 is fixedly connected to the square shell 43, and the other end of the return spring 46 is fixedly connected to the inner wall of the slide bar 411. When the two telescopic rods 41 are in the open state, the return spring 46 rebounds and pushes the square shell 43 to rotate, so that the support head 44 is in the same direction as the telescopic rod 41. When the two telescopic rods 41 are close to each other, the two push blocks 45 contact each other and slide into the telescopic rod 41, pushing the square shell 43 to rotate and compressing the return spring 46. At this time, as the square shell 43 rotates, the ends of the two support heads 44 away from the square shell 43 contact each other, thereby reducing the contact area with the lifting belt body 12 and ensuring that the force points of the lifting belt body 12 are concentrated.

[0050] like Figures 1 to 8 As shown:

[0051] The support rod 4 also includes two pairs of three-section slide rails 47, which are fixedly connected to the inner walls of the two sides of the two square shells 43 respectively. The telescopic ends of the three-section slide rails 47 are rotatably connected to the support head 44, which passes through the other end of the square shell 43 and is plugged and matched therewith. One end of the support head 44 is a conical structure, and the other end of the support head 44 is an arc structure. The three-section slide rail 47 is extended by pulling the support head 44, and the support head 44 is pulled out of the square shell 43 and then rotated 180 degrees, so that the shape of the contact position between the support head 44 and the lifting belt body 12 can be adjusted, and the anti-cutting performance of the lifting belt body 12 can be further tested through one end of the conical structure.

[0052] like Figures 1 to 12 As shown:

[0053] The pulling assembly 2 includes a top frame 20, a pair of rotating seats 21, a pair of winches 22, a steel cable 23, a motor 24, a speed regulating mechanism 25 and a clamping mechanism 26.

The clamping mechanism 26 is installed on the steel cable 23, and the clamping mechanism 26 is used to clamp the end of the lifting belt body 12. The motor 24 is installed on the top frame 20 through the speed regulating mechanism 25, and the motor 24 is used to drive the winch 22 to rotate. The end of the lifting belt body 12 is fixed by the clamping mechanism 26, and then the motor 24 is powered on to drive the winch 22 to rotate and reel in the steel cable 23, thereby lifting the supporting mechanism and tightening the lifting belt body 12. As the steel cable 23 is reeled in, the tension on the lifting belt body 12 gradually increases, and the strength of the lifting belt body 12 is determined by the degree of deformation of the lifting belt body 12.

[0054] like Figures 1 to 12 As shown:

[0055] The speed regulating mechanism 25 includes a moving frame 250, a first bevel gear 251 and a pair of second bevel gears 252. The moving frame 250 can be installed on the top frame 20 in a horizontally movable manner. One end of the moving frame 250 is fixedly connected to the motor 24. The output end of the motor 24 passes through the moving frame 250 and is coaxially connected to the first bevel gear 251. One end of the second bevel gear 252 passes through the rotating seat 21 and is coaxially connected to the winch 22. The motor 24 and the first bevel gear 251 are driven to move horizontally by the moving frame 250, so that the first bevel gear 251 has different working states when the moving frame 250 is in different positions, thereby controlling the number of winches 22 that the motor 24 can drive at the same time, and then increasing the number of rotating winches 22 to increase the speed of winding the steel cable 23, which can further detect the strength of the lifting belt body 12 when it is quickly pulled by force. When the moving frame 250 is located at the end away from the winch 22, the first bevel gear 251 meshes with one of the second bevel gears 252. At this time, the motor 24 drives one of the winches 22 to rotate, and the steel cable 23 is wound at a relatively slow speed, so that the lifting belt body 12 is slowly stressed. When the moving frame 250 is located at the end close to the winch 22, the first bevel gear 251 meshes with two second bevel gears 252 at the same time. At this time, the motor 24 drives the two winches 22 to rotate at the same time, and the steel cable 23 is wound at a relatively fast speed, so that the lifting belt body 12 is quickly stressed.

[0056] like Figures 1 to 12 As shown:

[0057] The speed regulating mechanism 25 also includes a round rod 253 and an electric push rod 254. The bottoms of both ends of the round rod 253 are fixedly connected to the top of the top frame 20. The top of the mobile frame 250 passes through the top frame 20 and is slidably connected to the outer periphery of the round rod 253. One end of the electric push rod 254 is fixedly connected to the round rod 253. The telescopic end of the electric push rod 254 passes through the mobile frame 250 and is fixedly connected thereto. When the electric push rod 254 is powered on, its telescopic end pushes the mobile frame 250 to move horizontally along the round rod 253, so as to realize the horizontal movement of the motor 24 and the first bevel gear 251. The round rod 253 is arranged parallel to the side wall of the first bevel gear 251 to ensure the smooth meshing between the first bevel gear 251 and the second bevel gear 252.

[0058] like Figures 1 to 13 As shown:

[0059] The clamping mechanism 26 includes a support plate 260, a roller 261, a pair of clamping plates 262, a guide rod 263, a screw 264 and a thrust spring 265. The roller 261 is rotatably connected to the inner wall of the support plate 260. The steel cable 23 is wound around the outer periphery of the roller 261 and is slidably connected to the groove on the outer periphery. When the steel cable 23 is wound, the roller 261 is driven to rotate to reduce friction. At the same time, the support plate 260 is lifted upward by the roller 261, thereby applying tension to the lifting belt body 12. The two clamping plates 262 are symmetrically arranged at both ends of the support plate 260, so that the forces at both ends of the lifting belt body 12 can be balanced, thereby improving the detection accuracy. The guide rod 263 passes through the support plate 260 and is fixedly connected thereto, the guide rod 263 passes through the clamping plate 262 and is slidably connected thereto, the screw rod 264 passes through the support plate 260 and is slidably connected thereto, one of the clamping plates 262 is threadedly connected to the outer periphery of the screw rod 264, the other clamping plate 262 is slidably connected to the outer periphery of the screw rod 264 and is fixedly connected to one end of a thrust spring 265, the thrust spring 265 is sleeved on the outer periphery of the screw rod 264, the other end of the thrust spring 265 is fixedly connected to the support plate 260, and the two protrusions on the screw rod 264 respectively conflict with the opposite ends of the two clamping plates 262. Insert the two ends of the lifting belt body 12 into the gap between the two clamping plates 262 and the support plate 260 respectively, and then rotate the screw 264. Through the threaded transmission between the screw 264 and one of the clamping plates 262, the gap between it and the support plate 260 is shortened. At the same time, the other clamping plate 262 is gradually approached to the support plate 260 under the push of the protrusion on the screw 264 and squeezes the thrust spring 265 to compress it. The two clamping plates 262 move along the guide rod 263 successively and approach each other. With the support plate 260, the two ends of the lifting belt body 12 can be clamped and fixed at the two ends of the support plate 260 respectively. After the inspection is completed, rotate the screw 264 in the opposite direction to make one of the clamping plates 262 move away from the support plate 260. At the same time, the thrust spring 265 rebounds and pushes the other clamping plate 262 away from the support plate 260, so that the disassembly can be completed.

[0060] like Figures 1 to 3 As shown:

[0061] Two anti-swing components 5 are symmetrically installed at both ends of the housing 30. The anti-swing components 5 include a rotating frame 50 and a tripod 51. The tripod 51 is rotatably connected to the outer periphery of the rotating frame 50, and the bottom of the rotating frame 50 is fixedly connected to the top of the raft 1. When the lifting belt body 12 breaks, the force on the broken part suddenly disappears, and the huge inertia will cause the lifting belt body 12 to be thrown out to both ends. When the lifting belt body 12 encounters the tripod 51, it will rotate around the tripod 51 and wrap around its periphery under the drive of inertia, and the impact force will drive the tripod 51 to rotate around the rotating rod, further absorbing the impact force to reduce the inertia of the lifting belt body 12, thereby preventing it from being thrown out and injuring people.

[0062] The present embodiment also provides a detection method for a detection device of a high-strength polyester fiber lifting belt, comprising the following steps: step 1: wrap the lifting belt body 12 to be detected around the periphery of multiple support rods 4 on the shell 30, so that the lifting belt body 12 and the support head 44 are in contact with each other, and then fix the two ends of the lifting belt body 12 on the clamping mechanism 26 to complete the fixation of the lifting belt body 12; step 2: drive the clamping mechanism 26 to rise through the pulling component 2 set on the frame 11, pull the lifting belt body 12, and detect the stress strength of the lifting belt body 12; step 3: push one group of support rods 4 to move through the hydraulic cylinder 32 on the support component 3, so that it slides out of the shell 30 and the two support rods 4 open to each other, which can increase the number of force points of the lifting belt body 12 and improve the reliability of the detection result; step 4: drive the motor 24 to move horizontally through the speed regulating mechanism 25, and the rising speed of the clamping mechanism 26 can be adjusted, which can further detect the force strength of the lifting belt body 12 when it is pulled quickly.

[0063] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not limiting, but are only for the convenience of clearly describing the positional relationship and function between the various components.
