Description

Technical Field

[0001] This utility model relates to the field of wire rope tension testing, and in particular to a wire rope tension testing device. Background Technology

[0002] To improve elevator safety, the steel wire ropes used in elevators undergo tension testing after production. Existing tension testing devices typically connect one end of the wire rope to a power mechanism and the other end to a tension gauge. The power mechanism pulls one end of the wire rope, and the tension gauge measures the rope's tension. However, to ensure stable binding, the wire rope is usually repeatedly wound around the connecting lifting ring before binding. During the testing process, the wire rope may tighten significantly, making it difficult to remove. To address this issue, patent application CN222144362U... The patent discloses a wire rope tension testing device, which is equipped with two wire rope fixing components. After the wire rope passes through multiple winding holes on the rod, it is pressed and fixed, making it less likely to loosen when the wire rope is under force. At the same time, it does not require complicated binding operations, making it easy to disassemble the wire rope after the test. This patent solves the problem of inconvenient disassembly of wire rope to a certain extent. However, its winding operation is still relatively complicated. Moreover, in actual use, after the test, due to excessive force, the wire rope deforms in each winding hole and is easily stuck in the winding hole, making it difficult to remove.

[0003] Therefore, a technical solution is needed to address the technical problems of complex installation and removal of wire ropes during the use of wire rope testing devices, and even the difficulty in removing the wire ropes after testing. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem that the installation and removal of wire ropes in the use of wire rope testing devices is complicated, and there is even a problem that the wire rope is difficult to remove after the test is completed, and to provide an elevator wire rope tension testing device.

[0005] This utility model provides a wire rope tension detection device, including a base, a fixed seat, a power mechanism, a tension gauge, and two mounting blocks. The fixed seat and the power mechanism are arranged opposite to each other on the top of the base. The tension gauge is connected to the fixed seat. The two mounting blocks are respectively connected to the ends of the tension gauge and the power mechanism. Each mounting block has a wire hole and a winding post on the top of the mounting block. A clamping component is provided on the winding post. The clamping component is used to press the wire rope wound on the winding post to the top surface of the mounting block.

[0006] This utility model discloses a wire rope tension testing device. In use, the two ends of the wire rope are connected to the mounting block. During the connection process, the wire rope first passes through the wire hole on the mounting block, then exits from the end face of the mounting block, and then winds around the winding post on the top surface of the mounting block. Finally, the wire rope is pressed tightly against the top surface of the mounting block by the clamping component on the winding post, thereby fixing the two ends of the wire rope. After the test is completed, the wire rope can be easily removed by loosening the clamping component on the winding post.

[0007] Preferably, an n-shaped block is provided in the middle of one end face of the mounting block, and the n-shaped block and the end face of the mounting block enclose a clearance zone for the passage of the wire rope.

[0008] One of the mounting blocks has an n-shaped block on its side connected to a tension gauge, and the other mounting block has an n-shaped block on its side connected to a power mechanism, which facilitates the passage of the wire rope through the end of the mounting block and avoids interference between the wire rope and the tension gauge or power mechanism.

[0009] Preferably, the clamping assembly includes a clamping nut, which is sleeved on the winding post.

[0010] After the wire rope is wound around the winding post, the wire rope is pressed against the top surface of the mounting block by tightening the nut, thus fixing the end of the wire rope. After the bolt is removed, the wire rope wound around the winding post can be easily removed.

[0011] Preferably, the clamping assembly further includes a pressure plate, which is sleeved on the winding post and positioned below the clamping nut for contact with the wire rope.

[0012] Adding a pressure plate between the wire rope and the clamping nut can increase the contact area between the wire rope and the pressure plate, allowing the coiled wire rope to be more tightly compressed by the pressure plate, thus improving the stability of the wire rope installation.

[0013] Preferably, the power mechanism includes a motor, the motor shaft is connected to a sleeve, the sleeve is threadedly connected to a screw, and the screw is used to connect to the mounting block.

[0014] The rotation of the motor drives the sleeve to rotate, and the sleeve is connected to the mounting block by a screw. When the screw is limited, the rotation of the sleeve can be converted into the linear motion of the screw, thereby achieving the purpose of tightening the wire rope.

[0015] Preferably, it further includes a first support base, and the screw is slidably connected to the first support base.

[0016] By setting a first support seat, the screw is slidably connected to the first support seat, so that the rotation of the sleeve can drive the screw to make linear motion in the axial direction, thereby pulling the wire rope located between the two mounting blocks.

[0017] Preferably, the screw has a slider in the middle, the slider is hexagonal prism shaped, and the first support seat has a through groove that matches the cross-sectional shape of the slider.

[0018] The screw and the first support seat are slidably connected. The hexagonal sliding mechanism provides radial restraint to the screw, preventing it from rotating under the radial force of the sleeve.

[0019] Preferably, it further includes a second support base, and the motor is disposed on the top surface of the second support base.

[0020] The second support can support the motor shaft at the height of the wire rope during the testing process, thereby enabling the connection and force transmission between the sleeve and the screw on the shaft.

[0021] Preferably, the base is provided with wheels at its bottom.

[0022] This makes the device easier to move and facilitates the testing of wire ropes in different workstations and workshops.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model provides an elevator wire rope tension testing device. By setting a wire-passing hole on the mounting block for connecting the wire rope and setting a winding post on the top surface of the mounting block, the wire rope passes through the wire-passing hole on the mounting block, exits from the end face of the mounting block, and is then wound onto the winding post on the top surface of the mounting block. The wire rope is pressed tightly to the top surface of the mounting block by the clamping component on the winding post. This makes the installation and removal of the wire rope during the wire rope testing process simpler and improves the efficiency of wire rope testing. Attached Figure Description

Example 1

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a wire rope 8 tension detection device includes a base 1, a fixed seat 2, a power mechanism 3, a tension gauge 4, and two mounting blocks 5. The fixed seat 2 and the power mechanism 3 are arranged opposite each other on the top of the base 1. The tension gauge 4 is connected to the fixed seat 2. The two mounting blocks 5 are respectively connected to the ends of the tension gauge 4 and the power mechanism 3. The mounting blocks 5 are provided with a wire hole 51. The top of the mounting blocks 5 is provided with a winding post 52. The winding post 52 is provided with a clamping component 53. The clamping component 53 is used to press the wire rope 8 wound on the winding post 52 to the top surface of the mounting blocks 5.

[0038] In use, the two ends of the wire rope 8 are connected to the mounting block 5 respectively. During the connection process, the wire rope 8 first passes through the wire hole 51 on the mounting block 5, then passes out from the end face of the mounting block 5, and then winds around the winding post 52 on the top surface of the mounting block. Finally, the wire rope 8 is pressed tightly to the top surface of the mounting block 5 by the clamping component 53 on the winding post 52, thereby fixing the two ends of the wire rope 8. After the test is completed, the wire rope 8 can be easily removed by loosening the clamping component 53 on the winding post 52.

[0039] Mounting block 5: An n-shaped block 54 is provided in the middle of one end face of the mounting block 5. The n-shaped block 54 and the end face of the mounting block 5 enclose a clearance zone for the passage of the wire rope 8. One n-shaped block 54 on the side of the mounting block 5 is connected to the tension gauge 4, and the other n-shaped block 54 on the side of the mounting block 5 is connected to the power mechanism 3, thereby facilitating the passage of the wire rope 8 from the end of the mounting block 5 and avoiding interference between the wire rope 8 and the tension gauge 4 or the power mechanism 3.

[0040] The clamping assembly 53 includes a clamping nut 531, which is sleeved on the winding post 52. After the wire rope 8 is wound on the winding post 52, the clamping nut 531 clamps the wire rope 8 to the top surface of the mounting block 5, thereby fixing the end of the wire rope 8. After the bolts are removed, the wire rope 8 wound on the winding post 52 can be easily removed. The clamping assembly 53 also includes a pressure plate 532, which is sleeved on the winding post 52 and is located below the clamping nut 531. It is used to abut against the wire rope 8, which can increase the contact area with the wire rope 8, so that the coiled wire rope 8 can be more compressed by the pressure plate 532, thereby improving the installation stability of the wire rope 8.

[0041] Power mechanism 3: includes a motor 31, the shaft of the motor 31 is connected to a sleeve 32, the sleeve 32 is threadedly connected to a screw 33, the screw 33 is used to connect to the mounting block 5;

[0042] Specifically, a first support seat 6 is provided on the top surface of the base 1. The screw 33 is slidably connected to the first support seat 6. By slidably connecting the screw 33 to the first support seat 6, the rotation of the sleeve 32 can drive the screw 33 to move linearly in the axial direction, thereby pulling the wire rope 8 located between the two mounting blocks 5. A slider 331 is provided in the middle of the screw 33. The slider 331 is hexagonal prism shaped. The first support seat 6 is provided with a through groove 61 that matches the cross-sectional shape of the slider 331, realizing the slidable connection between the screw 33 and the first support seat 6. The sliding of the hexagonal prism has a radial limit on the screw 33, preventing the screw 33 from rotating during the radial force of the sleeve 32.

[0043] Specifically, a second support seat 7 is provided on the top surface of the base 1, and the motor 31 is provided on the top surface of the second support seat 7. The second support seat 7 can support the rotating shaft of the motor 31 to the height of the wire rope 8 during the detection process, thereby realizing the connection and force transmission between the sleeve 32 on the rotating shaft and the screw 33.

[0044] Furthermore, the top surface of the base 1 is equipped with driving wheels 11, which makes the device easier to move and facilitates the inspection of steel wire ropes 8 in different work positions and workshops.
