Abstract
Description
Technical Field
[0001] This utility model relates to the field of Dyneema rope testing technology, specifically to a Dyneema rope tensile testing device. Background Technology
[0002] Dyneema rope is a high-performance synthetic fiber rope widely used in various fields due to its excellent strength and lightweight properties. Dyneema rope is made of polyethylene and has extremely high tensile strength and excellent wear resistance.
[0003] After the existing Dyneema ropes are manufactured, their strength needs to be checked. Some testing methods involve lifting them with a heavy object. Based on the tensile strength limit of the Dyneema rope, a corresponding weight is placed on a platform, and then the platform is lifted by a hoisting device using the Dyneema rope. The rope is then observed to see if it breaks. This provides a more direct way to test the tensile strength of the Dyneema rope.
[0004] However, the above method is intended to perform tensile testing on the Dyneema rope. But after the platform is lifted, it is often suspended in mid-air. If the Dyneema rope breaks, the platform will fall downwards, causing a collision with the equipment. The heavier the platform, the greater the collision damage, which inevitably damages the testing equipment. Therefore, it has certain shortcomings.
[0005] In conclusion, it is necessary to invent a Dyneema rope tension testing device. Utility Model Content
[0006] To address this issue, this utility model provides a Dyneema rope tension testing device to solve the problem that if the Dyneema rope breaks, the platform will fall downwards, causing a collision with the equipment. Furthermore, the heavier the platform, the greater the collision damage, inevitably leading to damage to the testing equipment.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a Dyneema rope tension testing device, comprising a base, a testing frame fixed to the top of the outer wall of the base, and testing components for testing the tension of the Dyneema rope being provided at both the upper and lower ends of the inner wall of the testing frame.
[0008] The testing component includes a placement plate and a lifting plate. The placement plate is located on the inner bottom side of the testing frame, and the lifting plate is located above the top of the outer wall of the placement plate. A connecting frame is connected to the top of the outer wall of the placement plate. The connecting frame and the lifting plate are provided with bottom and top lifting rings on opposite sides to fix the upper and lower ends of the Dyneema rope.
[0009] Preferably, a fixing rod is fixed at each of the four corners of the top of the outer wall of the placement plate, the bottom of the outer wall of the connecting frame is fixedly connected to the top of the outer wall of the fixing rod, and the bottom of the bottom lifting ring is fixedly connected to the center of the top of the outer wall of the connecting frame.
[0010] Preferably, a limit rod is fixed at the center of the top of the outer wall of the placement plate, and a counterweight is placed at the top of the outer wall of the placement plate and outside the limit rod to increase the weight of the placement plate. The counterweight is located inside the fixed rod.
[0011] Preferably, the inner wall of the base has a storage cavity, a partition is fixed at the center of the inner wall side of the storage cavity, and cabinet doors are hinged to the front end of the outer wall of the base and on the upper and lower sides of the partition.
[0012] Preferably, hydraulic cylinders are fixed on both sides of the top of the outer wall of the partition, and a support plate is provided at the bottom of the outer wall of the placement plate and at the corresponding position above the hydraulic cylinders.
[0013] Preferably, the top output end of the hydraulic cylinder passes through the top of the outer wall of the base and is fixedly connected to the center of the bottom of the outer wall of the support plate. The top of the outer wall of the base is provided with through holes at positions corresponding to the output ends of the hydraulic cylinders. The outer wall of the hydraulic cylinder is slidably connected to the inner wall of the through holes.
[0014] Preferably, pads are fixed to the front and rear sides of the top edge of the outer wall of the support plate, and rubber pads are fixed to the top edge of the outer wall of each pad.
[0015] Preferably, a lifting hydraulic cylinder is fixed to the top of the outer wall of the testing frame. The bottom output end of the lifting hydraulic cylinder passes through the top of the inner wall of the testing frame and is fixedly connected to the center of the top of the outer wall of the lifting plate. Guide rods are fixed to the top of the outer wall of the lifting plate and on both sides of the lifting hydraulic cylinder. The top of the inner wall of the testing frame is slidably connected to the outer wall of the guide rods by opening clearance holes.
[0016] The beneficial effects of this utility model are:
[0017] In this invention, after the placement plate is lifted by the hydraulic cylinder, the tension of the Dyneema rope can be detected by the counterweight on the placement plate. When the placement plate is lifted, the support plate can be moved upward by the hydraulic cylinder so that the pad moves below the placement plate but does not contact the placement plate. This allows the placement plate to fall onto the pad for support if the Dyneema rope breaks, thus preventing the placement plate from falling and impacting the device, and ensuring that the device can be used normally.

[0024] See attached document Figures 1-4This utility model provides a Dyneema rope tension testing device, including a base 100. A testing frame 200 is fixed to the top of the outer wall of the base 100. Testing components for testing the tension of the Dyneema rope are provided at both the upper and lower ends of the inner wall of the testing frame 200. The testing components include a placement plate 210 and a lifting plate 310. The placement plate 210 is located on the inner bottom side of the testing frame 200, and the lifting plate 310 is located above the top of the outer wall of the placement plate 210. A connecting frame 230 is connected to the top of the outer wall of the placement plate 210. The connecting frame 230 is used to fix the bottom lifting ring 231 to the top of the outer wall of the placement plate 210, and to fix the bottom lifting ring 231 to the top of the outer wall of the placement plate 210. The placement plate 210 is slidably connected to the inner wall of the testing frame 200. Fixing rods are fixed at the four corners of the top of the outer wall of the placement plate 210. 220, the bottom of the outer wall of the connecting frame 230 is fixedly connected to the top of the outer wall of the fixing rod 220.

The bottom end of the bottom lifting ring 231 is fixedly connected to the center of the top of the outer wall of the connecting frame 230. The center of the top of the outer wall of the placement plate 210 is fixed with a limit rod. The top of the outer wall of the placement plate 210 and outside the limit rod are all equipped with counterweights 211 to increase the weight of the placement plate 210. The counterweights 211 are set inside the fixing rod 220. The limit rod is set to prevent the counterweights 211 from shifting when placed on the placement plate 210. It can limit the counterweights 211.
[0025] The inner wall of the base 100 has a storage cavity 120, the bottom of which can store the counterweight 211 for testing. A partition 130 is fixed at the center of the inner wall side of the storage cavity 120. Cabinet doors 110 are hinged to the front end of the outer wall of the base 100 and on the upper and lower sides of the partition 130. Hydraulic cylinders 240 are fixed on both sides of the top of the outer wall of the partition 130. Support plates 250 are provided at the bottom of the outer wall of the placement plate 210 and at the corresponding position above the hydraulic cylinders 240. The top output end of the hydraulic cylinders 240 passes through the top of the outer wall of the base 100 and is fixedly connected to the center of the bottom of the outer wall of the support plate 250. Through holes are provided at the top of the outer wall of the base 100 at the positions corresponding to the output ends of the hydraulic cylinders 240. The outer wall of the 40 is slidably connected to the inner wall of the through hole. The top and rear sides of the outer wall of the support plate 250 are fixed with pads 251, and the top of the outer wall of the pads 251 are fixed with rubber pads. Specifically, when the placement plate 210 is lifted by the device, the personnel can control the two hydraulic cylinders 240 to extend through the controller, so that the hydraulic cylinders 240 can push the support plate 250 to move upward, so that the pads 251 can be below the placement plate 210. In this way, when the placement plate 210 falls, the pads 251 can support the bottom of the placement plate 210 and prevent the placement plate 210 from falling and being damaged. The hydraulic cylinders 240 need to be selected to be able to support the placement plate 210 plus the counterweight 211. The specific model is selected according to the actual size.
[0026] Both the connecting frame 230 and the lifting plate 310 are provided with a bottom lifting ring 231 and an upper lifting ring 330 on opposite sides to fix the upper and lower ends of the Dyneema rope. The bottom lifting ring 231 and the upper lifting ring 330 can fix the upper and lower ends of the Dyneema rope. The top of the outer wall of the testing frame 200 is fixed with a lifting hydraulic cylinder 300. The bottom output end of the lifting hydraulic cylinder 300 passes through the top of the inner wall of the testing frame 200 and is fixedly connected to the center of the top of the outer wall of the lifting plate 310. The top of the outer wall of the lifting plate 310 and on both sides of the lifting hydraulic cylinder 300 are fixed with guide rods 320. The top of the inner wall of the testing frame 200 is slidably connected to the outer wall of the guide rods 320 through the opening of the clearance hole. The lifting hydraulic cylinder 300 can pull the lifting plate 310 up and down through the output shaft, so that the lifting plate 310 can lift the bottom lifting ring 231 and the connecting frame 230 through the upper lifting ring 330.
[0027] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above instructions, then connect an external power supply to all electrical equipment, and control the operation of the device through an external controller. After completion, personnel can fix the upper and lower ends of the Dyneema rope to be tested to the upper lifting ring 330 and the lower lifting ring 231 respectively. Then, personnel can open the cabinet door 110 and place the placement plate 210 stored at the bottom of the storage cavity 120 on the top of the outer wall of the placement plate 210. A gravity sensor for detecting the weight of the counterweight 211 can be installed at the bottom of the inner wall of the placement plate 210, allowing personnel to easily check the weight of the counterweight 211. After the counterweight 211 is placed, personnel can control the lifting via the controller. The output end of the lifting hydraulic cylinder 300 retracts, enabling the lifting hydraulic cylinder 300 to lift the lifting plate 310 upwards. The lifting plate 310, through the upper lifting ring 330 and the bottom lifting ring 231, can lift the connecting frame 230 and the placement plate 210 upwards. During the lifting process, the controller can control the two hydraulic support cylinders 240 to extend, allowing the hydraulic support cylinders 240 to push the support plate 250 upwards, so that the pad 251 is positioned below the placement plate 210. In this way, if the placement plate 210 falls, the pad 251 can support the bottom of the placement plate 210, preventing the placement plate 210 from falling and being damaged. After the inspection is completed, the personnel can move the placement plate 210 downwards to reset it, and then the personnel can untie the Dyneema rope for inspection.
