Description

Technical Field

[0001] This utility model relates to the field of metal wire rope testing technology, and in particular to a high-temperature environment tensile simulation testing device for metal wire rope. Background Technology

[0002] Metal wire rope is a high-strength cable made of multiple metal wires woven or twisted together in a specific structure. It is widely used in construction, mining, marine engineering, elevator manufacturing, bridge construction, and many other fields. It not only possesses extremely high tensile strength but also good flexibility and fatigue resistance, enabling it to work stably in various harsh environments. The core component of metal wire rope is its internal steel wires, which are twisted into strands and then multiple strands are twisted around a core (which can be a fiber core or a metal core).

[0003] Existing tensile simulation tests for metal wire ropes involve fixing one end of the wire rope to a fixed clamp and connecting the other end to a movable actuator. The tension applied by the actuator is gradually increased until the wire rope breaks, and the maximum tensile force and deformation during this process are recorded. This method can determine the basic mechanical properties of the wire rope, such as yield strength, tensile strength, and elongation. However, in many practical applications, metal wire ropes may need to operate in high-temperature environments, such as in the metallurgical industry, thermal power plants, or aerospace. If the test cannot simulate these high-temperature conditions, the obtained performance data is only applicable to room temperature conditions and cannot accurately predict the performance of the wire rope at high temperatures. Under high-temperature conditions, the behavior of metallic materials changes significantly. For example, high temperatures may cause creep (i.e., gradually increasing plastic deformation over time under constant stress) in the wire rope, or a decrease in its strength and hardness.

[0004] Therefore, it is necessary to design a high-temperature environment tensile simulation testing device for metal wire ropes to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the limitations of high-temperature tensile testing devices for metal wire ropes, which are widely used in high-temperature environments such as metallurgy, power, and aerospace, where data obtained from high-temperature simulation is only applicable to room temperature and cannot accurately reflect their high-temperature performance, and considering the drawbacks of high temperatures potentially causing creep or changes in material behavior such as decreased strength and hardness, this invention provides a high-temperature tensile simulation testing device for metal wire ropes.

[0006] The technical solution of this utility model is: a high-temperature environment tensile simulation testing device for metal wire rope, comprising a test box, a controller, an electric push rod, a connecting rod, a rangefinder, a sensing block, and a snap-fit ​​assembly. The controller is fixedly connected to the right side of the test box, and the electric push rod is fixedly connected to the rear of the test box. The electric push rod is electrically connected to the controller. A connecting rod is fixedly connected to the telescopic rod of the electric push rod. The front part of the connecting rod passes into the interior of the test box. A rangefinder is fixedly connected to the top of the test box and is electrically connected to the controller. A sensing block is fixedly connected to the top of the connecting rod and is electrically connected to the rangefinder. A snap-fit ​​assembly is provided inside the test box and at the bottom of the connecting rod. The device also includes a fixed frame, an electric heating tube, a heat-conducting plate, and a temperature sensor. Fixed frames are fixedly connected to both sides of the bottom of the test box. Electric heating tubes are fixedly connected inside each of the two fixed frames and are electrically connected to the controller. A heat-conducting plate is fixedly connected to the top of each of the two fixed frames. A temperature sensor is fixedly connected inside the test box and is electrically connected to the controller.

[0007] Furthermore, the test chamber is made of high-temperature resistant and heat-insulating material.

[0008] Furthermore, the snap-fit ​​assembly includes a fixing block, a knob, a sleeve, a locking block, a screw, a pinion, and a large gear. The lower end of the connecting rod and the inside of the test box are both fixedly connected to symmetrically distributed fixing blocks. The right side of each fixing block is rotatably connected to a knob. Limiting grooves are symmetrically opened on one side of each fixing block. Snap-fit ​​holes are opened on both sides of the left side of each fixing block. Sleeves are slidably connected in each of the two limiting grooves. Locking blocks are fixedly connected to the left side of each sleeve. A screw is threadedly connected inside each sleeve. A pinion is fixedly connected to the right side of each screw. A large gear is fixedly connected to the right side of each knob. Both large gears mesh with the corresponding two pinions.

[0009] Furthermore, it also includes protective covers. The right side of both fixed blocks is fixedly connected to the protective covers, and the large gear and two small gears on the same side are located inside the corresponding protective covers.

[0010] Furthermore, it also includes an inner cylinder, a sliding rod, a blocking block, and a spring. The test box has an inner cylinder embedded and fixedly fitted on both sides of the top. A sliding rod is slidably connected inside each of the two inner cylinders. A blocking block is fixedly connected to the bottom of each of the two sliding rods. A spring is connected between each of the two blocking blocks and the corresponding inner cylinder. The two springs are wound around the corresponding sliding rods.

[0011] Furthermore, it also includes a sealing door, a pull block, a magnetic block, and an electromagnet. The front of the test box is symmetrically connected to the sealing door in a sliding manner. A pull block is fixedly connected to one side of the front of each of the two sealing doors. Magnetic blocks are fixedly connected to both sides of one of the sealing doors, and electromagnets are fixedly connected to both sides of the other sealing door. Both electromagnets are electrically connected to the controller.

[0012] The beneficial effects are as follows: 1. This utility model controls the start and stop of the electromagnet through a controller, realizing the automatic locking and releasing of the sealed door, improving operational safety and sealing performance; 2. The large gear drives the small gears on both sides to rotate the screw, causing the clamping block to clamp or release the metal wire rope, realizing a quick clamping function and improving testing efficiency; 3. The electric heating tube, in conjunction with the heat-conducting plate and temperature sensor, can accurately simulate a high-temperature environment, improving the accuracy of test data; 4. The electric push rod drives the fixed block to stretch the metal wire rope, and in conjunction with the sensor and rangefinder, displacement monitoring and fracture judgment are realized during the stretching process, ensuring the authenticity and reliability of the test results.

[0013] 2. This utility model uses changes in air pressure inside the test chamber to push the blocking block upwards, causing the spring to compress and release the inner cylinder channel, thus achieving automatic discharge of high-pressure gas. When the air pressure drops to the set value, the spring resets and drives the blocking block downwards to reseal the inner cylinder, thereby achieving automatic adjustment and sealing of air pressure. Air pressure control is achieved through mechanical linkage, requiring no additional power drive, and is responsive, safe and reliable. Attached Figure Description

Detailed Implementation

[0024] Example: A high-temperature environment tensile simulation testing device for metal wire ropes, such as... Figures 1-9 As shown, the test box includes a test chamber 1, a controller 101, an electric push rod 2, a connecting rod 3, a rangefinder 4, a sensing block 5, a fixing block 6, a knob 7, a sleeve 10, a locking block 11, a screw 12, a pinion 13, a gear 14, and a protective cover 15. The controller 101 is screwed onto the front right side of the test chamber 1, and the electric push rod 2 is screwed onto the rear side of the test chamber 1. The electric push rod 2 is electrically connected to the controller 101. The telescopic rod of the electric push rod 2 extends upward and is screwed onto the connecting rod 3. The front end of the connecting rod 3 extends downward and penetrates into the test chamber 1. Inside, a rangefinder 4 is screwed onto the top front of the test chamber 1. The rangefinder 4 is electrically connected to the controller 101. A sensor block 5 is screwed onto the top front of the connecting rod 3. The sensor block 5 is electrically connected to the rangefinder 4. The bottom of the test chamber 1 and the lower end of the connecting rod 3 are equipped with snap-fit ​​components. The test chamber 1 also includes a fixing frame 16, a heating element 17, a heat-conducting plate 18, and a temperature sensor 19. Fixing frames 16 are screwed onto the left and right sides of the bottom of the test chamber 1. Heating elements 17 are screwed into each of the two fixing frames 16. Both heating elements 17 are connected to the controller 101. The controller 101 is electrically connected. Heat-conducting plates 18 are screwed onto the top of both fixed frames 16. A temperature sensor 19 is screwed onto the right side of the inside of the test chamber 1. The temperature sensor 19 is electrically connected to the controller 101. The test chamber 1 is made of high-temperature resistant heat-insulating material. Fixed blocks 6, symmetrically distributed vertically, are screwed onto the lower end of the connecting rod 3 and the middle of the bottom of the test chamber 1. A knob 7 is rotatably connected to the right side of each of the two fixed blocks 6. Limiting grooves 8 are symmetrically formed on the front and back sides of the two fixed blocks 6 where they are close to each other. The left side of each fixed block 6 has two... Each side has a snap-fit ​​hole 9. Each of the two limiting grooves 8 has a sleeve 10 slidably connected to it. Each of the two sleeves 10 has a snap-fit ​​block 11 installed on its left end by screws. Each sleeve 10 has a screw rod 12 threadedly connected inside. Each screw rod 12 has a small gear 13 welded to its right end. Each knob 7 has a large gear 14 welded to its right end. Each of the two large gears 14 meshes with the corresponding two small gears 13. Each of the two fixing blocks 6 has a protective cover 15 installed on its right side by screws. The large gear 14 and the two small gears 13 on the same upper and lower side are located inside the corresponding protective cover 15.

[0025] like Figure 1 , Figure 7 and Figure 9 As shown, it also includes an inner cylinder 20, a sliding rod 21, a blocking block 23, and a spring 22. The test box 1 has an inner cylinder 20 embedded and fixedly fitted on the top left and right sides. The two inner cylinders 20 are slidably connected to the sliding rod 21. The bottom of the two sliding rods 21 is welded with a blocking block 23. The two blocking blocks 23 are connected to the corresponding inner cylinders 20 with a spring 22. The two springs 22 are wrapped around the corresponding sliding rods 21.

[0026] like Figure 1 and Figure 9 As shown, it also includes a sealing door 24, a pull block 25, a magnetic block 26, and an electromagnet 27. The front of the test box 1 is symmetrically connected to the sealing door 24 by sliding. The two sealing doors 24 are each screwed on the side of their front sides that are close to each other. The sealing door 24 on the left side is screwed on both the top and bottom sides. The sealing door 24 on the right side is screwed on both the top and bottom sides. Both electromagnets 27 are electrically connected to the controller 101.

[0027] When the device is needed, first turn off the electromagnet 27 via the controller 101 to deactivate its magnetic attraction. Then, the operator opens the two sealing doors 24 to the sides to expose the test area. Next, insert both ends of the metal wire rope to be tested into the clamping holes 9 in sequence, and rotate the knob 7 to drive the large gear 14 to rotate, thereby driving the small gears 13 on both sides to rotate synchronously. The small gears 13 drive the screw 12 to rotate, causing the sleeve 10 to move to the left along the limiting groove 8. Finally, the clamping block 11 firmly clamps the metal wire rope. After fixing, the operator closes the sealing door 24. 4. The door closes in the middle. The controller 101 then activates the electromagnet 27, causing it to magnetically attract the magnetic block 26, thus locking the sealing door 24 to prevent accidental opening during testing. Subsequently, the controller 101 activates the heating element 17, transferring heat through the heat-conducting plate 18 to the interior of the test chamber 1, simulating a high-temperature environment. A temperature sensor monitors the temperature inside the chamber in real time. Once the preset value is reached, the data is fed back to the controller 101, which then shuts off the heating element 17 to stop heating. Next, the controller 101 activates the electric push rod 2, whose extension rod pushes the connecting... Rod 3 moves the upper fixed block 6 upward, thereby pulling one end of the metal wire rope for a tensile test. Simultaneously, the sensing block 5 mounted on the fixed block 6 rises synchronously during the tensile process. When the metal wire rope breaks due to excessive force, the sensing block 5 stops moving. At this point, the rangefinder 4 detects the displacement change and transmits the data to the controller 101, recording the maximum tensile distance and relevant mechanical parameters before breakage. After the test, the operator again uses the controller 101 to turn off the electromagnet 27, unlock the sealing door 24, and manually open it, then rotates the knob 7 in the opposite direction. This causes the large gear 14 to reverse, driving the small gear 13 to rotate the screw 12 in the opposite direction, which in turn drives the sleeve 10 to move to the right along the limiting groove 8, releasing the clamping force of the clamping block 11 on the metal wire rope, making it easier to remove the tested sample. Repeating the above steps allows for testing the next batch of metal wire ropes. When the temperature inside the test chamber 1 rises, the internal air pressure gradually increases. Subsequently, the air pressure pushes the blocking block 23 upward, causing the spring 22 to compress and deform. High-pressure gas is discharged from the inner cylinder 20 outside the chamber. When the air pressure drops to a certain value, the blocking block 23 can move downward to its original position to block the inner cylinder 20.
