Description

Technical Field

[0001] The present application relates to the technical field of wire rope tension testing, and in particular to an electronic tension testing machine for wire ropes. Background Art

[0002] Wire ropes are widely used in mining, lifting, cableway, port, ocean and other industries. Since used wire ropes generally have defects such as broken wires, wear, rust, deformation, etc., their defects and carrying capacity are directly related to the safety of on-site personnel, equipment, and hoisting objects. For a long time, my country has adopted manual visual inspection and regular mandatory scrapping to ensure safe production. This approach cannot accurately detect various defects of wire ropes, which will not only cause safety hazards, but also cause the wire ropes that are still useful to be scrapped prematurely, resulting in huge waste. Therefore, how to achieve non-destructive testing of wire ropes is an urgent problem that my country needs to solve.

[0003] In the related art, a utility model patent with patent number CN212568222U discloses a multi-purpose electronic tensile testing machine, which includes a testing machine base, a support column and a lifting screw are arranged on the testing machine base, a lifting plate is arranged between the support column and the lifting screw, a connecting rod is arranged on the lifting plate, an adjusting nut and an adjusting rod are arranged on the connecting rod, and a fixing clamp is arranged on the adjusting nut. When the steel wire is tested, the steel wire is fixed to the fixing clamp, and then the steel wire is tightened by adjusting the adjusting nut, but the adjusting nut cannot be removed from the connecting rod. When the device is used for a long time, the adjusting nut will rust, thereby affecting the tightening degree of the steel wire. Summary of the invention

[0004] In order to facilitate the disassembly of the adjusting nut and improve the stability of the steel wire on the testing machine, the present application provides an electronic tensile testing machine for a steel wire rope.

[0005] The electronic tensile testing machine for steel wire rope provided in this application adopts the following technical solution:

[0006] An electronic tensile testing machine for a steel wire rope comprises a testing machine base, wherein two sliding rods are arranged on the testing machine base, a lifting device is arranged between the two sliding rods on the testing machine base, a lifting plate is arranged at one end of the lifting device away from the testing machine base, both ends of the lifting plate are slidably connected to the two sliding rods, a fixed rod sleeve is arranged at one side of the lifting plate away from the testing machine base, the length direction of the fixed rod sleeve is perpendicular to the lifting plate, a fixed rod is arranged on the fixed rod sleeve along the length direction of the fixed rod sleeve, a clamping disk is arranged at one end of the fixed rod away from the fixed rod sleeve, a steel wire rope is inserted into the clamping disk, and a clamping assembly for clamping the steel wire rope is also arranged on the locking disk.

[0007] By adopting the above technical solution, when it is necessary to perform a tension test on the steel wire rope, the steel plastic is first inserted between the two clamping disks, and then the steel wire rope is clamped by the clamping assembly. When the testing machine is used for too long, the tightening assembly can be replaced in time, thereby improving the stability of the steel wire rope on the testing machine.

[0008] Optionally, a clamping hole is formed on the clamping disc, and the clamping assembly includes a clamping rod, the clamping rod is inserted into the clamping hole, and a clamping nut is threadedly connected to the clamping rod.

[0009] By adopting the above technical solution, when clamping the wire rope, first insert the wire rope into the clamping disk, and then insert the clamping rod into the clamping hole. When the clamping rod is completely in contact with the wire rope, tighten the clamping nut. When the clamping nut is in contact with the clamping disk, the wire rope is fixed, thereby increasing the stability of the wire rope on the testing machine.

[0010] Optionally, the fixing rod sleeve is provided with a reinforcement component for reinforcing the fixing rod sleeve and the fixing rod.

[0011] By adopting the above technical solution, the reinforcement assembly can adjust the height of the locking plate from the lifting plate, thereby increasing the flexibility of the wire rope tension test. At the same time, when the fixed rod sleeve and the fixed rod need to be replaced, the fixed rod sleeve and the fixed rod can also be disassembled by disassembling the reinforcement assembly.

[0012] Optionally, a plug-in hole is provided on the fixed rod sleeve, and the length direction of the plug-in hole is perpendicular to the length direction of the fixed rod sleeve. The reinforcement component includes a locking rod, which is inserted into the plug-in hole and passes through the fixed rod to protrude out of the outside of the fixed rod sleeve. Locking nuts are threadedly connected at both ends of the locking rod.

[0013] By adopting the above technical solution, when fixing the fixing rod sleeve and the fixing rod, first the fixing rod is inserted into the fixing rod sleeve, then the locking rod is inserted into the insertion hole, and finally the two ends of the locking rod are fixed by the locking nut, thereby increasing the stability of the wire rope tension test.

[0014] Optionally, a bellows is sleeved on the outer side of the lifting device.

[0015] By adopting the above technical solution, the bellows can play a certain protective effect on the lifting component of the tensile testing machine, thereby increasing the service life of the lifting component.

[0016] Optionally, a vertical rod is fixedly connected to the base of the testing machine, and a sensor is arranged on the vertical rod.

[0017] By adopting the above technical solution, when the testing machine is conducting a wire rope tension test, the lifting plate moves on the sliding rod along the length direction of the sliding rod. When the lifting plate abuts against the sensor, the sensor transmits a signal to the lifting assembly, so that the lifting assembly drives the lifting plate to move in the opposite direction, thereby reducing manual operation.

[0018] Optionally, a top plate is provided at one end of the sliding rod away from the testing machine base, and the top plate is used to connect the two sliding rods, and one end of the vertical rod away from the testing machine base is also connected to the top plate.

[0019] By adopting the above technical solution, the top plate can increase the overall stability of the device and reduce the possibility of deformation of the device.

[0020] Optionally, there are two sensors, one of which is fixedly connected to an end of the vertical rod close to the testing machine base, and the other is fixedly connected to an end of the vertical rod away from the testing machine base.

[0021] By adopting the above technical solution, the two sensors can further increase the overall automation of the device and reduce manual operations.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the wire rope needs to be tested for tension, first insert the steel plastic between the two locking discs, and then clamp the wire rope through the clamping assembly. When the test machine is used for too long, the clamping assembly can be replaced in time, thereby improving the stability of the wire rope on the test machine;

[0024] 2. When clamping the wire rope, first insert the wire rope into the locking disc, then insert the clamping rod into the clamping hole. When the clamping rod is completely in contact with the wire rope, tighten the clamping nut. When the clamping nut is in contact with the locking disc, the wire rope is fixed, thereby increasing the stability of the wire rope on the testing machine.

[0025] 3. When fixing the fixed rod sleeve and the fixed rod, first insert the fixed rod into the fixed rod sleeve, then insert the locking rod into the plug-in hole, and finally fix the two ends of the locking rod with the locking nut to increase the stability of the wire rope tension test.

[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0030] The present application embodiment discloses an electronic tensile testing machine for a steel wire rope. Figure 1 The test machine includes a rectangular test machine base 1, on which two sliding rods 11 are arranged, and the two sliding rods 11 are arranged at the midline position of the test machine base 1. A top plate 2 is fixedly connected to one end of the sliding rod 11 away from the test machine base 1, and the top plate 2 is used to further connect and fix the two sliding rods 11 to increase the overall stability of the device. A lifting plate 3 is slidably arranged between the two sliding rods 11, and a lifting plate 3 is provided between the two sliding rods 11 on the test machine base 1 for controlling the lifting plate 3 to move along the sliding rods 11. A lifting device (not shown in the figure) that moves up and down is provided with a bellows 4 on the outside of the lifting device, and the bellows 4 can play a certain protective role for the lifting device as a whole. A fixed rod sleeve 5 is fixedly connected to the side of the lifting plate 3 away from the testing machine base 1, and the length direction of the fixed rod sleeve 5 is perpendicular to the lifting plate 3. A fixed rod 51 is arranged in the fixed rod sleeve 5 along the length direction of the fixed rod sleeve 5. One end of the fixed rod 51 away from the lifting plate 3 protrudes from the fixed rod sleeve 5 and is provided with a clamping disk 6, and a clamping assembly 7 is arranged on the clamping disk 6.

[0031] Reference Figure 1 The side of the top plate 2 close to the lifting plate 3 has the same structure as the lifting plate 3 , and the clamping assembly 7 on the top plate 2 and the clamping assembly 7 on the lifting plate 3 correspond to each other, and a steel wire 8 is arranged between the two clamping assemblies 7 .

[0032] When the steel wire 8 is subjected to a tensile test, one end of the steel wire 8 is first fixed to the clamping assembly 7 on the top plate 2, and then the other end of the steel wire 8 is fixed to the tightening assembly of the lifting plate 3 by adjusting the height of the lifting plate 3. Then, the lifting device is started to make the lifting plate 3 slide along the sliding rod 11, and the maximum tensile force that the steel wire 8 can withstand is measured during the sliding process. When the clamping effect of the clamping assembly 7 of the testing machine is reduced, the clamping assembly 7 can be removed and replaced, thereby reducing the possibility of the steel wire 8 falling off the clamping assembly 7 during the experiment and increasing the stability of the steel wire 8 on the testing machine.

[0033] Reference Figure 1 and Figure 2 A storage groove 61 is provided on the side of the clamping disc 6 away from the connecting rod, and the length direction of the storage groove 61 is parallel to the length direction of the connecting rod. The steel wire 8 is inserted in the storage groove 61. A clamping hole 62 is also provided on the clamping disc 6. The length direction of the clamping hole 62 is perpendicular to the length direction of the storage groove 61, and the storage groove 61 and the clamping hole 62 are connected to each other. The clamping assembly 7 includes a clamping rod 71, which is inserted in the clamping hole 62, and the length of the clamping rod 71 is greater than the length of the clamping hole 62. The end of the clamping rod 71 away from the storage groove 61 is threadedly connected with a clamping nut 72.

[0034] When the locking nut 72 is in the locked state, the locking nut 73 is locked and the locking nut 78 is in the locked state, and the locking nut 73 is in the locked state.

[0035] Reference Figure 1 and Figure 2 The fixing rod 51 and the fixing rod sleeve 5 are threadedly connected, and an insertion hole 52 is provided on the side wall of the fixing rod sleeve 5, and a reinforcement component 9 is arranged in the insertion hole 52. The reinforcement component 9 includes a locking rod 91 threadedly connected in the insertion hole 52, the locking rod 91 passes through the fixing rod 51 and protrudes from the other side of the sliding rod 11 sleeve, and locking nuts are threadedly connected at both ends of the locking rod 91, and the two locking nuts abut against the outer wall of the fixing rod sleeve 5.

[0036] When the device itself becomes rusty and needs to be replaced, first rotate the two locking nuts to disengage the locking nuts from the locking rod 91, then remove the locking rod 91 from the insertion hole 52, and finally rotate the fixing rod 51 to remove the fixing rod 51 from the fixing rod sleeve 5, so that the fixing rod 51 and the clamping plate 6 can be disassembled for replacement, and finally the replaced fixing rod 51, clamping plate 6 and other structures can be reinstalled on the fixing rod sleeve 5. On the one hand, the reinforcement component 9 can further reinforce the fixing rod 51 and the fixing rod sleeve 5, and on the other hand, the device can be disassembled through the reinforcement component 9, thereby increasing the overall flexibility of the device.

[0037] Reference Figure 1 A vertical rod 12 is fixedly connected to the side of the testing machine base 1 where the two sliding rods 11 are away from each other, and one end of the vertical rod 12 away from the testing machine base 1 is fixedly connected to the top plate 2. Two sensors 121 are fixedly connected to the vertical rod 12, one of the sensors 121 is located at the bottom of the vertical rod 12, and the other sensor 121 is located on the side of the top plate 2 close to the lifting plate 3.

[0038] When conducting a tensile test on the steel wire 8, when the lifting plate 3 slides to the position of the sensor 121, the sensor 121 will transmit a signal to the lifting device, thereby causing the lifting plate 3 to move in the opposite direction. The sensor 121 can control the lifting position of the lifting plate 3, reducing the possibility of damage to the device caused by excessive movement of the lifting plate 3.

[0039] Reference Figure 1 A connecting block 53 is fixedly connected to one end of the fixing rod 51 close to the locking disk. The connecting block 53 is hinged to the clamping disk 6. When fixing the steel wire 8, if it is inconvenient to fix the steel wire 8, the angle of the fixed steel wire 8 can be adjusted by rotating the clamping disk 6, thereby increasing the flexibility of the device.

[0040] The implementation principle of an electronic tensile testing machine in an embodiment of the present application is as follows: when a tensile test is performed on the steel wire 8, first one end of the steel wire 8 is inserted into the storage groove 61 of the clamping disk 6, and then the clamping rod 71 is inserted into the clamping hole 62, and the clamping nut 72 is threadedly connected to the clamping rod 71, thereby clamping the steel wire 8, and then the other end of the steel wire 8 is clamped to the clamping disk 6 on the lifting plate 3 using the same steps, and finally the lifting device is started to move the lifting plate 3 to test the tension of the steel wire 8. When the clamping rod 71 needs to be replaced, the clamping nut 72 can be directly removed from the clamping rod 71, and then the clamping rod 71 can be taken out of the clamping hole 62 to complete the replacement, thereby reducing the possibility of the steel wire 8 detaching from the clamping disk 6 and increasing the stability of the steel wire 8 on the clamping disk 6.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
