Description

Technical Field

[0001] This utility model belongs to the field of elevator wire rope technology, specifically relating to an elevator wire rope tension testing device. Background Technology

[0002] As a crucial load-bearing component of the elevator system, the uniformity and consistency of the elevator's tension directly affect the safety and stability of elevator operation. Regularly checking the tension of the wire rope is an essential part of elevator maintenance.

[0003] Currently, common methods for testing wire rope tension often employ handheld force gauges or simple fixed clamps. These traditional devices typically suffer from the following problems: First, the clamping mechanism is poorly designed, making the wire rope prone to slippage or localized damage during testing, affecting the accuracy of the test results and potentially damaging the wire rope. Second, the lack of an effective centering and guiding structure leads to inconsistent force direction, introducing measurement errors. Third, the operation process is cumbersome, often requiring multiple people to cooperate, resulting in low efficiency and difficulty in achieving rapid, repeatable, and standardized testing. For example, some existing clamps rely solely on bolts for direct tightening, resulting in inaccurate clamping force control and an inability to adapt to wire ropes of different diameters.

[0004] Therefore, there is an urgent need in this field for an elevator wire rope tension testing device that can achieve stable and reliable clamping, is easy to operate, and can guarantee testing accuracy and consistency. Utility Model Content

[0005] The purpose of this utility model is to provide an elevator wire rope tension testing device, which aims to solve the problems of the existing clamping mechanism design being simple, prone to wire rope slippage or local damage during the testing process, affecting the accuracy of the test results and potentially damaging the wire rope; lacking an effective centering and guiding structure, resulting in inconsistent force direction and introducing measurement errors; cumbersome operation process, often requiring multiple people to cooperate, resulting in low efficiency; and difficulty in achieving fast, repeatable, and standardized testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An elevator wire rope tension testing device includes:

[0008] Base;

[0009] The tension tester body is located at the upper end of the base;

[0010] A fixed frame is fixedly connected to the upper end of the base, and an installation frame is fixedly connected to the inner surface of the fixed frame. A placement seat is connected to the upper end of the installation frame.

[0011] A telescopic rod is fixedly connected to the upper inner wall of the mounting frame. A connecting block is fixedly connected to the lower end of the telescopic rod, and a pressure seat is fixedly connected to the lower end of the connecting block. Anti-slip pads are provided on the inner surfaces of both the placement seat and the pressure seat.

[0012] A pressing mechanism is provided within the mounting frame to clamp the elevator wire rope being tested.

[0013] As a preferred embodiment of this utility model, the pressing mechanism includes:

[0014] Two sliding shells are rotatably connected to the upper inner wall of the mounting frame via a rotating shaft. Sliding rods are slidably connected to the inner surfaces of the two sliding shells. The lower ends of the two sliding rods are rotatably connected to the upper end of the connecting block via a rotating shaft.

[0015] Two springs are respectively disposed on the inner surfaces of two sliding shells. Each inner surface of the two sliding shells is slidably connected to a compression shell. The lower ends of the two compression shells and the upper ends of the two sliding rods are respectively fixedly connected.

[0016] As a preferred embodiment of this utility model, two parallel rods are fixedly connected to the upper and lower ends of the fixed frame and the mounting frame, and parallel blocks are slidably connected to the circumferential surfaces of the two parallel rods. The adjacent ends of the two parallel blocks are fixedly connected to the two sides of the lower pressure seat.

[0017] In a preferred embodiment of this utility model, a fastening seat is fixedly connected to one end of the placement seat, and a conical seat is fixedly connected to one end of the fastening seat. A conical shell is threaded onto the outer surface of the conical seat.

[0018] As a preferred embodiment of this utility model, the upper end of the base is fixedly connected to a mounting base, and the lower end of the base is fixedly connected to a plurality of support columns.

The parallel block slides along the parallel rod to ensure vertical movement; simultaneously, the sliding rod compresses the spring, causing the lower pressure seat and placement seat to clamp the middle of the wire rope together. Anti-slip pads prevent slippage, providing a uniform and flexible clamping force to the wire rope during testing. This effectively prevents slippage and surface damage, ensuring the reliability of test data and extending the service life of the wire rope.

[0036] Example 1

[0037] Please see Figure 1-5 The present invention provides the following technical solution:

[0038] An elevator wire rope tension testing device includes:

[0039] Base 1;

[0040] The tension tester body 28 is located at the upper end of the base 1;

[0041] Fixed frame 4 is fixedly connected to the upper end of base 1. Mounting frame 5 is fixedly connected to the inner surface of fixed frame 4. Placement seat 7 is connected to the upper end of mounting frame 5.

[0042] Telescopic rod 6 is fixedly connected to the upper inner wall of the mounting frame 5. A connecting block 20 is fixedly connected to the lower end of the telescopic rod 6, and a lower pressure seat 16 is fixedly connected to the lower end of the connecting block 20. Anti-slip pads 19 are provided on the inner surfaces of both the placement seat 7 and the lower pressure seat 16.

[0043] The pressing mechanism is installed within the mounting frame 5 to clamp the elevator wire rope under test.

[0044] In a specific embodiment of this utility model, the base 1 serves as the basic support structure for the entire testing instrument. It is typically made of metal to ensure stability and durability. The tension of the elevator wire rope is tested using the tension testing instrument body 28. The fixed frame 4 is fixed to the upper end of the base 1 to support and fix other components. The inner surface of the fixed frame 4 is fixedly connected to the mounting frame 5. The upper end of the mounting frame 5 is connected to the placement seat 7 for placing the elevator wire rope to be tested. The telescopic rod 6 is fixed to the upper inner wall of the mounting frame 5, and its lower end is fixedly connected to the connecting block 20. The telescopic rod 6 is used to drive the lower pressure seat 16 to move up and down, thereby clamping and releasing the wire rope. The anti-slip pad 19 is set on the inner surface of the placement seat 7 and the lower pressure seat 16 to increase the friction with the wire rope, prevent the wire rope from slipping during the test, and ensure test accuracy. When the lower pressure seat 16 moves downward, the connecting block 20 drives the sliding rod 24 to slide within the sliding shell 21, and the spring 22 is compressed to provide a reverse force to ensure uniform clamping force. When the telescopic rod 6 retracts, the spring 22 pushes the compression shell 23 and the sliding rod 24 to reset, causing the lower pressure seat 16 to rise smoothly. This design improves the stability and reliability of clamping, prevents the wire rope from shifting during testing, provides a uniform and flexible clamping force to the wire rope during testing, effectively prevents the wire rope from slipping and surface damage, ensures the reliability of test data and extends the service life of the wire rope, and provides precise movement and accurate test results, further improving test accuracy. It is also convenient to operate, highly adaptable, has a high degree of structural integration, and good stability.
