Abstract
Description
Technical Field
[0001] This utility model relates to the field of tension testing technology, and in particular to a static tension tester for mining steel wire ropes. Background Technology
[0002] In mining operations, wire ropes are core components in critical processes such as hoisting and traction, and their static tension directly affects equipment safety and production efficiency. Abnormal static tension in wire ropes (such as excessive tension leading to overload or insufficient tension leading to slippage) can cause safety accidents such as rope breakage and equipment shutdown. Therefore, it is necessary to conduct precise testing of their static tension regularly.
[0003] Currently, traditional wire rope tension testing equipment has the following limitations:
[0004] 1. Insufficient testing accuracy: Some devices indirectly judge tension through simple mechanical structures (such as levers and springs), which are easily affected by factors such as wire rope deviation and frictional resistance, resulting in large data errors; and lack a stable limiting structure, the wire rope is prone to shaking during the test, further reducing the accuracy of the test.
[0005] 2. Poor ease of operation: Adjusting the detection position requires disassembling or adjusting the components multiple times, making it difficult to quickly adapt to wire ropes of different diameters and tension ranges. This results in low adaptability and increases manual operation costs.
[0006] 3. Limited Functionality: It can only perform tension detection and cannot simultaneously handle the maintenance needs of wire ropes. In mining environments, wire ropes are exposed to dust and moisture for extended periods, and their lifespan is easily shortened due to dryness and wear. Separate lubrication operations require additional equipment and procedures, increasing the complexity of the workflow. Utility Model Content

[0008] A static tension tester for mining steel wire rope includes a fixed bracket, and a tension testing component is provided on the surface of the fixed bracket;
[0009] The tension testing assembly includes a support slide fixedly connected to the bottom of a fixed bracket, and a threaded rod rotatably disposed on the surface of the fixed bracket. An adjustment seat is rotatably connected to the bottom of the threaded rod. A guide slider is fixedly disposed at the bottom of the adjustment seat, and a pressure sensor is fixedly disposed on the surface of the adjustment seat. Limiting grooves are provided at both the left and right ends of the support slide, and the inner wall of the limiting groove is rotatably connected to a limiting roller via a rotating shaft.
[0010] A lubrication assembly is provided on the back of the fixed bracket. The lubrication assembly is used to lubricate the surface of the wire rope. The lubrication assembly includes a limiting mounting frame fixedly connected to the back of the fixed bracket, and an oil sprayer fixedly connected to the bottom wall of the limiting groove.
[0011] In a preferred embodiment, the position limiting roller of the fuel injector corresponds to and is located directly below the limiting roller. The liquid storage bottle is made of plastic and has a return spring on its inner wall. The return spring is used to restore the deformation of the liquid storage bottle after it has been squeezed.
[0012] In a preferred embodiment, an oil outlet tube is fixedly installed at the bottom of the liquid storage bottle, and a diversion shell is fixedly installed on the back of the fixed bracket. The upper surface of the diversion shell is provided with a limiting insertion hole that matches the oil outlet tube. The oil outlet tube is inserted and installed inside the diversion shell through the limiting insertion hole, and a one-way drain valve is fixedly installed on the surface of the oil outlet tube.
[0013] In a preferred embodiment, two flow dividers are fixedly embedded in the inner rear wall of the flow divider housing. The ends of the two flow dividers away from the flow divider housing extend into the interior of the support slide, and the output ends of the two flow dividers are fixedly connected to the input end of the fuel injector.
[0014] In a preferred embodiment, a liquid filling tube is fixedly embedded at the top of the liquid storage bottle, and a sealing cap is threaded to the end of the liquid filling tube. An air inlet tube is fixedly embedded on the surface of the liquid storage bottle, and a one-way air inlet valve is provided on the surface of the air inlet tube.
[0015] In a preferred embodiment, the top of the guide slider overlaps with the sensing end of the pressure sensor, and a limiting mounting shell is fixedly provided on the surface of the fixed bracket.

[0017] As can be seen from the above, the static tension tester for mining steel wire ropes provided by this utility model has the following technical effects.
[0018] 1. Precise Tension Testing and Convenient Operation: The tension testing assembly, through the cooperation of a threaded rod, adjusting seat, and pressure sensor, accurately captures the static tension of the wire rope. The adjusting seat moves stably under the drive of the threaded rod, and the guide slider tightly engages with the sensing end of the pressure sensor, reducing external interference. The limiting roller is connected to the limiting groove of the supporting slide via a rotating shaft, both limiting the wire rope and reducing the impact of friction on the test results through rolling contact, thus improving data accuracy. Simple Operation and Easy Adjustment: The operating handle at the top of the threaded rod facilitates manual adjustment, allowing for quick adjustment of the adjusting seat position according to different diameters or tension requirements. The limiting mounting shell provides a sliding limit for the adjusting seat, ensuring stability during adjustment and reducing operational difficulty.
[0019] 2. Integrated lubrication function extends wire rope service life: Real-time lubrication reduces wear. The lubrication component is integrated with the tension testing structure. Lubricant in the storage bottle is delivered to the nozzle through the oil outlet pipe, distribution shell, and distribution conduit. The nozzle is located directly below the limit roller, ensuring precise lubrication as the wire rope passes the limit roller. Lubrication is completed simultaneously with the test, preventing wear caused by dry friction. The lubrication operation is efficient and controllable: The storage bottle is made of plastic and has a built-in return spring, automatically restoring its deformation after compression. A one-way drain valve enables quantitative drainage. The one-way air inlet valve on the air inlet pipe ensures stable air pressure inside the storage bottle, preventing liquid backflow. The addition pipe design facilitates lubrication replenishment without disassembling the entire structure, improving maintenance efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figures 1-5 The static tension tester for mining wire ropes is mainly used for testing the static tension of wire ropes in mining scenarios. It also integrates wire rope lubrication function. Its overall structure includes a fixed bracket 1, a tension testing component 2, and a lubrication component 3.
[0030] The fixed bracket 1 serves as the basic frame of the entire equipment, providing installation support for other components. The tension testing component 2 is directly mounted on the front and bottom of the fixed bracket 1 to perform static tension testing of the wire rope; the lubrication component 3 is installed on the back of the fixed bracket 1 and inside the support slide 201 to lubricate the wire rope during testing. The two components form an organic whole through the fixed bracket 1, realizing integrated operation of "testing + lubrication".
[0031] It is worth noting that the tension testing component 2 is the core part for tension detection. It consists of a support slide 201, a threaded rod 202, an adjusting seat 203, a guide slider 204, a pressure sensor 205, a limiting groove 206, a limiting roller 207, an operating handle 208, and a limiting mounting shell 209. The positional relationship and function of each component are as follows:
[0032] Support slide 201: Fixedly connected to the bottom end of the fixed bracket 1, it is the main support structure through which the wire rope passes and bears the force. Two limiting grooves 206 are symmetrically formed at its left and right ends. The inner walls of the grooves are rotatably connected to limiting rollers 207 via rotating shafts. The limiting rollers 207 not only limit the wire rope, preventing it from shifting during testing, but also reduce friction with the wire rope through rolling contact, thus reducing the interference of friction on the test results and improving the accuracy of tension detection.
[0033] Threaded rod 202: Rotatably mounted on the surface of fixed bracket 1, with operating handle 208 fixedly connected to the top end and rotatably connected to adjusting seat 203 at the bottom end. By rotating operating handle 208, threaded rod 202 can be rotated, thereby driving adjusting seat 203 to move up and down. The operation is simple, and the position of adjusting seat 203 can be quickly adjusted according to the wire rope specifications to adapt to different testing needs.
[0034] Adjustment seat 203: The back is slidably connected to the surface of the fixed bracket 1, and is inserted into the through hole of the limiting mounting shell 209. The limiting mounting shell 209 is fixed to the surface of the fixed bracket 1. The through holes on its upper and lower surfaces match the size of the adjustment seat 203, which guides and limits the movement of the adjustment seat 203, preventing the adjustment seat 203 from shifting or shaking during movement and ensuring test stability.
[0035] Guide slider 204 and pressure sensor 205: Guide slider 204 is fixed to the bottom end of adjusting seat 203, and its top is tightly connected to the sensing end of pressure sensor 205; pressure sensor 205 is fixed to the surface of adjusting seat 203. When the wire rope is under force, the pressure is transmitted to pressure sensor 205 through guide slider 204. The force transmission path is direct and stable, reducing signal loss and improving the accuracy of tension detection.
[0036] It is worth noting that the lubrication assembly 3 is used to lubricate the wire rope during testing, extending its service life. It consists of a limiting mounting frame 301, an oil nozzle 302, a storage bottle 303, an oil outlet pipe 304, a flow divider shell 305, a one-way drain valve 306, a flow divider conduit 307, a liquid filling pipe 308, and an air inlet pipe 309. The positional relationship and function of each component are as follows: Storage bottle 303 and limiting mounting frame 301: The storage bottle 303 is inserted into the limiting mounting frame 301, which is fixed to the back of the fixing bracket 1. The limiting mounting frame 301 fixes the storage bottle 303, preventing it from falling off during equipment operation, adapting to the vibration environment of the mine, and ensuring the stability of the lubrication assembly 3. The storage bottle 303 is made of plastic and has a return spring on its inner wall. After being squeezed, it can automatically recover its deformation, facilitating control of the lubricant discharge and allowing for reuse of the storage bottle 303.
[0037] Oil outlet tube 304 and diverter shell 305: The oil outlet tube 304 is fixed to the bottom end of the storage bottle 303, and its end is inserted into the inside of the diverter shell 305 through the limiting insertion hole on the upper surface of the diverter shell 305; the diverter shell 305 is fixed to the back of the fixing bracket 1 and is used to divert the lubricating fluid to both sides. A one-way drain valve 306 is installed on the surface of the oil outlet tube 304 to prevent the lubricating fluid from flowing back into the storage bottle 303 and to ensure the one-way and stability of the liquid delivery.
[0038] Diverter ducts 307 and injectors 302: Two diverter ducts 307 are fixedly embedded in the inner rear wall of the diverter housing 305. The ends of both ducts, away from the diverter housing 305, extend into the interior of the support slide 201, and their output ends are fixedly connected to the input end of the injector 302. The injector 302 is fixed to the inner bottom wall of the limiting groove 206, corresponding to the limiting roller 207 and located directly below the limiting roller 207. When the wire rope passes through the limiting roller 207, the injector 302 can accurately spray lubricant onto the surface of the wire rope, achieving "synchronous lubrication during testing" and reducing wire rope wear.
[0039] Liquid filling pipe 308 and air inlet pipe 309: Liquid filling pipe 308 is fixedly embedded in the top of liquid storage bottle 303, and the end is threaded with a sealing cap to facilitate the replenishment of lubricating fluid. The sealing cap can prevent liquid leakage or impurities from entering. Air inlet pipe 309 is fixedly embedded in the surface of liquid storage bottle 303. The surface is equipped with a one-way air inlet valve to ensure that the liquid storage bottle 303 can smoothly draw in air after being squeezed, maintain the internal air pressure balance, and ensure the continuous discharge of lubricating fluid.
[0040] Working principle: When in use, the steel wire rope to be tested is first passed through the two limiting grooves 206 of the support slide 201, so that the steel wire rope comes into contact with the limiting roller 207. The limiting roller 207 supports the steel wire rope by rolling, which not only limits its left and right deviation, but also reduces contact friction.
[0041] Subsequently, the tension testing assembly 2 is adjusted by rotating the operating handle 208: the operating handle 208 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the adjusting seat 203 to slide up and down along the surface of the fixed bracket 1 (the through hole of the limiting mounting shell 209 guides the adjusting seat 203 to ensure stable movement). When the adjusting seat 203 moves down, the guide slider 204 gradually approaches the wire rope until it contacts the surface of the wire rope and applies appropriate pressure; at this time, the static tension of the wire rope is transmitted to the pressure sensor 205 through the guide slider 204, and the pressure sensor 205 converts the force signal into an electrical signal to complete the tension detection (during this process, the rolling contact of the limiting roller 207 and the stable movement of the adjusting seat 203 together ensure the accuracy of the test data).
[0042] Simultaneously with the tension test, the wire rope can be lubricated via the lubrication assembly 3: Manually squeezing the storage bottle 303 causes the lubricant inside to enter the distribution shell 305 under pressure through the oil outlet pipe 304 (with a one-way drain valve 306 preventing backflow). The lubricant is divided into two paths within the distribution shell 305, delivered to the corresponding nozzles 302 via two distribution conduits 307. Since the nozzles 302 are located directly below the limiting roller 207, the wire rope is evenly sprayed with lubricant as it passes, achieving a lubrication effect. Releasing the storage bottle 303 causes the return spring on its inner wall to restore its deformation. At this time, the one-way air inlet valve of the air inlet pipe 309 opens, allowing outside air to enter the storage bottle 303 to replenish the air pressure, preparing for the next drain. If the lubricant in the storage bottle 303 is insufficient, the sealing cap of the filling pipe 308 can be opened to directly replenish it without disassembling the entire structure, making operation convenient.
[0043] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
