Description
Technical Field
[0001] This utility model relates to the field of rope tension testing technology, and in particular to a friction hoist rope tension tester. Background Technology
[0002] Friction hoists are mining hoisting equipment that rely on friction to drive the hoisting container to move vertically up and down along the shaft. Due to their advantages, they are widely used in mining and construction. Their working principle is to use the friction between the wire rope and the friction wheel to transmit power. During the hoisting process, the friction wheel rotates, and the friction drives the wire rope, thereby causing the hoisting container connected to the wire rope to rise or fall.
[0003] When friction hoists are used for a long time, excessive tension differences between the ropes can easily lead to overload on some ropes, accelerating rope wear and reducing their service life. In order to increase the working safety of the device, a rope tension tester is needed to test the tension of the wire ropes on the friction hoist.
[0004] The working principle of existing rope tension testers on the market is to place the wire rope on the pulley seat, and then move the pulley seat upward to press the wire rope under test, so that the wire rope is in complete contact with the pressing block, thereby obtaining the tension of the wire rope. However, since the wire rope is placed directly on the pulley seat, it is easy for the wire rope to deviate on the pulley during the upward process, and the force on different parts of the rope is uneven, which will affect the accuracy of the test results of the rope tension tester. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a friction hoist rope tension tester, which aims to improve the problem that the wire rope is prone to deviating on the pulley during use, thus affecting the accuracy of the test results.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a friction-type hoist rope tension tester, comprising a housing, an L-shaped plate provided on the bottom rear side of the housing, a locking handle threadedly connected to the bottom of the L-shaped plate, a U-shaped plate fixedly connected to the top of the locking handle passing through the L-shaped plate, hollow rods rotatably connected to the inside of the U-shaped plate and the left and right sides of the inside of the housing, the front sides of multiple hollow rods respectively passing through the corresponding U-shaped plate and the housing, a bidirectional lead screw rotatably connected to the front end of the hollow rod, the rear end of the bidirectional lead screw passing through the hollow rod, a limiting groove formed on the top of the hollow rod, movable blocks threadedly connected to the front and rear sides of the outer walls of multiple bidirectional lead screws, clamping plates fixedly connected to the tops of multiple movable blocks respectively passing through the corresponding limiting grooves, and a testing mechanism provided in the middle of the bottom end of the housing, the testing mechanism being used for convenient and rapid testing of rope tension.
[0007] With the above technical solution, the rope is less likely to deviate outside the hollow pole during the ascent process, and the force on each part of the rope is uniform, thus ensuring the accuracy of the test results of the rope tension tester.
[0008] As a further description of the above technical solution:
[0009] The testing mechanism includes a clamping block, which is located on the upper front side of the L-shaped plate. A connecting block is fixedly connected to the middle bottom of the housing. A button is fixedly connected to the bottom of the connecting block. A T-shaped rod is fixedly connected to the bottom of the button. A spring is provided on the outside of the T-shaped rod. One end of the spring is fixedly connected to the bottom of the button, and the other end of the spring is fixedly connected to the top of the T-shaped rod. The bottom of the T-shaped rod is fixedly connected to the top of the clamping block.
[0010] Using the above technical solution, the rope can gradually squeeze the clamping block as it moves upward. At this time, the T-shaped rod on the clamping block will move upward to squeeze the spring. After the button is squeezed, the tension data of the rope can be obtained through the control panel, which can quickly test the tension of the rope.
[0011] As a further description of the above technical solution:
[0012] The left and right sides of the interior of the multiple hollow rods are fixedly connected to limit rods, and the left and right sides of the multiple movable blocks are slidably connected to the outer sides of the corresponding limit rods.
[0013] The above technical solution can limit the movement trajectory of the active block, allowing it to move more smoothly.
[0014] As a further description of the above technical solution:
[0015] The rear side of the L-shaped plate is provided with a sliding groove, and the rear side of the U-shaped plate is slidably connected inside the sliding groove.
[0016] The above technical solution can further limit the movement trajectory of the U-shaped plate.
[0017] As a further description of the above technical solution:
[0018] The rear top of the L-shaped plate is threaded with a bolt, the front end of which passes through the L-shaped plate and the housing in sequence.
[0019] By using the above technical solution, loosening the bolts can release the limiting fixation of the L-shaped plate, at which point it can be removed for easy carrying.
[0020] As a further description of the above technical solution:
[0021] A control panel is fixedly connected to the front left side of the housing, and a socket is fixedly connected to the top right side of the housing.
[0022] The above technical solution allows the socket to conveniently charge other devices.
[0023] As a further description of the above technical solution:
[0024] A support base is fixedly connected to the top left side of the housing, and an antenna is rotatably connected to the top of the support base.
[0025] The above technical solution can further improve the signal reception of the device.
[0026] As a further description of the above technical solution:
[0027] A handle is fixedly connected to the top of the housing, and a rubber sleeve is fixedly connected to the outside of the handle.
[0028] The above technical solution can further increase the friction between the worker's palm and the device.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, rotating the bidirectional lead screw can drive the movable blocks on both sides to move in the limiting groove. The clamping plate at the top of the movable block will move towards the middle to limit and clamp the wire rope.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a friction-type hoist rope tension tester, comprising a housing 1, an L-shaped plate 3 disposed on the bottom rear side of the housing 1, a locking handle 4 threadedly connected to the bottom of the L-shaped plate 3, a U-shaped plate 5 fixedly connected to the top of the locking handle 4 through the L-shaped plate 3, hollow rods 6 rotatably connected to the inside of the U-shaped plate 5 and the left and right sides of the inside of the housing 1, the front sides of multiple hollow rods 6 respectively penetrating the corresponding U-shaped plate 5 and the housing 1, a bidirectional lead screw 8 rotatably connected to the front end of the hollow rod 6, the rear end of the bidirectional lead screw 8 penetrating the hollow rod 6, a limit groove 7 formed on the top of the hollow rod 6, and the front of the multiple bidirectional lead screws 8... Each of the rear sides is threaded with a movable block 9. The top of each movable block 9 passes through a corresponding limiting groove 7 and is fixedly connected to a clamping plate 10. A testing mechanism 2 is provided at the bottom center of the housing 1. The testing mechanism 2 is used to conveniently and quickly test the tension of the rope. The left and right sides of the interior of each of the hollow rods 6 are fixedly connected to limiting rods 11. The left and right sides of each of the movable blocks 9 are slidably connected to the outer side of the corresponding limiting rods 11. A sliding groove 12 is provided on the rear side of the L-shaped plate 3. The rear side of the U-shaped plate 5 is slidably connected inside the sliding groove 12. A bolt 13 is threadedly connected to the top of the rear side of the L-shaped plate 3. The front end of the bolt 13 passes through the L-shaped plate 3 and the housing 1 in sequence.
[0041] Specifically, rotating the bidirectional lead screw 8 can drive the movable blocks 9 located on both sides of the limiting groove 7 to move accordingly. As the movable blocks 9 move, the clamping plate 10 on top of them will also move closer to the center position, thereby performing an effective limiting clamping operation on the wire rope. During the process of the rope rising, it is not easy for it to deviate from the outside of the hollow rod 6. This design ensures that every part of the rope can bear the force evenly during the testing process, thus greatly improving the accuracy of the rope tension tester's test results. Loosening the bolt 13 can release the limiting fixation of the L-shaped plate 3, at which point it can be removed for easy carrying.
[0042] Reference Figure 1 , Figure 3 and Figure 4 The testing mechanism 2 includes a clamping block 201, which is located on the upper front side of the L-shaped plate 3. A connecting block 202 is fixedly connected to the middle of the bottom end of the housing 1. A button 203 is fixedly connected to the bottom of the connecting block 202. A T-shaped rod 204 is fixedly connected to the bottom of the button 203. A spring 205 is provided on the outside of the T-shaped rod 204. One end of the spring 205 is fixedly connected to the bottom of the button 203, and the other end of the spring 205 is fixedly connected to the top of the T-shaped rod 204. The bottom of the T-shaped rod 204 is fixedly connected to the top of the clamping block 201.
[0043] Specifically, as the rope moves upward, it gradually compresses the clamping block 201. As this process continues, the T-shaped rod 204 on the clamping block 201 also moves upward, thereby compressing the spring 205. As the button 203 is pressed, the value displayed on the control panel 14 is updated accordingly. This value is the actual tension value of the wire rope. After the entire test is completed, by rotating the locking handle 4 in the opposite direction, the wire rope can be moved away from the clamping block 201. At this time, the spring 205 will release the previously compressed force, and the button 203 will return to its original position. In this way, the tension value of the tested rope can be obtained quickly and accurately, thereby significantly improving the practicality of the device.
[0044] Reference Figure 1 A control panel 14 is fixedly connected to the front left side of the housing 1, a socket 15 is fixedly connected to the top right side of the housing 1, a support base 16 is fixedly connected to the top left side of the housing 1, and an antenna 17 is rotatably connected to the top of the support base 16.
[0045] Specifically, the tension of the rope being measured can be accurately determined through the control panel 14, while the antenna 17 can further improve the signal reception of the device.
[0046] Reference Figure 1 A handle 18 is fixedly connected to the top of the housing 1, and a rubber sleeve 19 is fixedly connected to the outside of the handle 18.
[0047] Specifically, the handle 18 makes the device easy to carry, while the rubber sleeve 19 further increases the friction between the worker's palm and the device.
[0048] Working principle: When using this device, first carry the device to the position to be tested using handle 18. Then place the wire rope on the friction hoist between the upper and lower hollow rods 6. Then rotate the double-acting screw 8 to drive the movable blocks 9 on both sides to move in the limiting grooves 7. The clamping plate 10 on the top of the movable block 9 will move towards the middle to limit and clamp the wire rope. At this time, rotating the locking handle 4 can drive the wire rope to move upward to complete the subsequent rope testing. During the ascent, the rope is not easy to deviate outside the hollow rod 6. The force on each part of the rope is uniform, which can ensure the accuracy of the rope tension tester test results.
[0049] Furthermore, as the rope moves upward, it gradually compresses the clamping block 201. At this time, the T-shaped rod 204 on the clamping block 201 moves upward and compresses the spring 205. After the button 203 is compressed, the value displayed on the control panel 14 is the actual tension value of the steel wire rope being tested. When the test is completed, the locking handle 4 is rotated in the opposite direction to move the steel wire rope away from the clamping block 201. At this time, the spring 205 will release the compressing force and cause the button 203 to rebound. The tension of the tested rope can be obtained quickly and accurately, thereby improving the practicality of the device.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
