Description

Technical Field

[0001] This utility model relates to the technical field of elevator wire rope testing devices, specifically a testing device for elevator wire ropes. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves along at least two rigid tracks perpendicular to the horizontal plane or at an angle of less than 15° to the vertical. There are also escalators, where steps are mounted on a continuous track, commonly known as moving walkways or automatic stairs. These are fixed lifting devices serving designated floors. Vertical elevators have one car. In current elevators, the steel wire rope bears the entire load. Due to the inertia of the elevator car during operation and the changes in load during long-term operation, the steel wire rope cannot maintain its initial good condition after prolonged use. Therefore, it is necessary to test the wire rope's tensile strength and breakage data before it leaves the factory.

[0003] According to the authorized announcement number CN219625199U, an elevator wire rope slack detection device is disclosed, including a main body of the device. The main body of the device includes: a mounting frame, which is disposed on an outer fixed surface; a slack-breaking assembly for performing a tensile test on the wire rope, which is disposed on the mounting frame; and a driving component for driving the slack-breaking assembly, which is disposed on the mounting frame. By setting up the main body of the device, in use, the user first uses the handle to pull the protective plate upward, and the protective plate moves above the slack-breaking assembly. Then, the user uses a pneumatic clamp to fix both ends of the wire rope. Subsequently, the user releases the handle, and the protective plate returns to its original position. By setting up the protective plate, the broken and flying wire rope can be isolated to prevent injury to the user. Furthermore, the tempered glass inner viewing port facilitates the user's observation of the detection process.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, it is found that, when applied, the aforementioned equipment can solve the problems that existing detection methods are not scientific enough, cannot simulate the force at both ends of the steel wire, and that the steel wire will be blown away after breaking, which can easily cause injury to the user.

[0005] However, in actual use, the above-mentioned equipment uses pneumatic clamps to fix the wire rope. However, this method relies too much on the air source system and has certain limitations. Moreover, when the air source is not stable enough, the wire rope is prone to move during clamping and stretching, which affects the accuracy of the test results. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a testing device for elevator wire ropes, which has the advantage of auxiliary fixing. It solves the problem that the above-mentioned devices use pneumatic clamps to fix the wire ropes, but this method is too dependent on the air source system and has certain limitations. Moreover, when the air source is not stable enough, the wire rope is prone to move during clamping and stretching, thus affecting the test results.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detection device for elevator wire ropes, comprising a base plate, a mounting plate, a bidirectional lead screw, a support block, and a break-off component. The mounting plate is fixedly connected to the top of the base plate, the support block is fixedly connected to the left and right sides of the front of the mounting plate, the bidirectional lead screw is movably connected inside the support block, the break-off component is threadedly connected to the left and right sides of the surface of the bidirectional lead screw, a base plate is fixedly connected to the front of the break-off component, a placement block is fixedly connected to the bottom of the base plate, a pressure plate is provided on the top of the placement block, a pressing assembly is movably connected to the top of the pressure plate, a reinforcing assembly is fixedly connected to the bottom of the pressure plate, and limit assemblies are fixedly connected to the left and right sides of the top of the pressure plate.

[0008] In a preferred embodiment of this invention, the clamping assembly includes a screw, which is movably connected to the top of the pressure plate. A fixing plate is threaded onto the surface of the screw, and the back of the fixing plate is fixedly connected to the base plate.

[0009] As a preferred embodiment of this utility model, the reinforcing component includes an arc-shaped block, which is fixedly connected to the bottom of the pressure plate, and the top of the placement block is provided with an arc-shaped groove, which is used in conjunction with the arc-shaped block.

[0010] As a preferred embodiment of this utility model, the limiting component includes a limiting rod, which is fixedly connected to the left and right sides of the top of the pressure plate. The left and right sides of the top of the fixed plate are provided with limiting holes for use with the limiting rod. The limiting holes are through holes, and the limiting rod is located inside the limiting holes.

[0011] As a preferred embodiment of this invention, protective pads are attached to both the bottom of the arc-shaped block and the top of the arc-shaped groove, and the protective pads are made of natural rubber.

[0012] As a preferred embodiment of this utility model, a mounting hole is provided at the center of the top of the pressure plate, and a bearing is fixedly engaged inside the mounting hole. The screw is movably connected to the pressure plate through the bearing.

[0013] As a preferred embodiment of this invention, a rotary handle is fixedly connected to the top of the screw, and the rotary handle is used to operate the screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a base plate, a placement block, a pressure plate, and a clamping assembly, fixes the base plate and the tensioning component. When the placement block and clamping assembly are installed, the clamping assembly moves the pressure plate downwards to fix the wire rope, thereby clamping and fixing the wire rope through the placement block. The use of this mechanical structure offers a wider range of applications compared to pneumatic clamps, reducing limitations. It solves the problem that the aforementioned equipment uses pneumatic clamps to fix the wire rope, which relies heavily on the air supply system, has certain limitations, and is prone to movement during clamping and stretching when the air supply is unstable, thus affecting the test results. This invention achieves an auxiliary fixing effect.

[0016] 2. By setting up a clamping component, when the operator needs to use the pressure plate to fix the wire rope, the operator rotates the screw, and the screw will drive the pressure plate to move downward through the support of the fixing plate, so that the pressure plate clamps and fixes the wire rope through the placement block, thus ensuring the stability of the wire rope fixed by the pressure plate.

[0017] 3. By setting up a reinforcing component, when the pressure plate moves downward, it will simultaneously drive the arc-shaped block downward, so that the arc-shaped block drives the wire rope to move into the arc-shaped groove, thereby forming an interlocking state between the arc-shaped block and the arc-shaped groove, which makes the fixing of the wire rope more stable and avoids the wire rope from slipping during the stretching process.

[0022] 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.

[0023] like Figures 1 to 3 As shown, the detection device for elevator wire ropes provided by this utility model includes a base plate 1, a mounting plate 2, a bidirectional lead screw 3, a support block 4, and a break-off component 5. The mounting plate 2 is fixedly connected to the top of the base plate 1. The support block 4 is fixedly connected to the left and right sides of the front of the mounting plate 2. The bidirectional lead screw 3 is movably connected inside the support block 4. The break-off component 5 is threadedly connected to the left and right sides of the surface of the bidirectional lead screw 3. A base plate 6 is fixedly connected to the front of the break-off component 5. A placement block 7 is fixedly connected to the bottom of the base plate 6. A pressure plate 8 is provided on the top of the placement block 7. A pressing component 9 is movably connected to the top of the pressure plate 8. A reinforcing component 10 is fixedly connected to the bottom of the pressure plate 8. Limiting components 11 are fixedly connected to the left and right sides of the top of the pressure plate 8.

[0024] refer to Figure 2 The clamping assembly 9 includes a screw 91, which is movably connected to the top of the pressure plate 8. A fixing plate 92 is threadedly connected to the surface of the screw 91, and the back of the fixing plate 92 is fixedly connected to the base plate 6.

[0025] As a technical optimization of this utility model, by setting up the clamping component 9, when the operator needs to use the pressure plate 8 to fix the wire rope, the operator rotates the screw 91, and the screw 91 will drive the pressure plate 8 to move downward through the support of the fixing plate 92, so that the pressure plate 8 clamps and fixes the wire rope through the placement block 7, thus ensuring the stability of the pressure plate 8 in fixing the wire rope.

[0026] refer to Figure 2 The reinforcing component 10 includes an arc-shaped block 101, which is fixedly connected to the bottom of the pressure plate 8. An arc-shaped groove 102 is provided on the top of the placement block 7, which is used in conjunction with the arc-shaped block 101.

[0027] As a technical optimization of this utility model, by setting up the reinforcing component 10, when the pressure plate 8 moves downward, it will simultaneously drive the arc block 101 to move downward, so that the arc block 101 drives the wire rope to move into the arc groove 102, thereby forming an interlocking state between the arc block 101 and the arc groove 102, thus making the fixing of the wire rope more stable and avoiding the slippage of the wire rope during the stretching process.

[0028] refer to Figure 2 and Figure 3The limiting component 11 includes a limiting rod 111, which is fixedly connected to the left and right sides of the top of the pressure plate 8. The left and right sides of the top of the fixing plate 92 are provided with limiting holes 112 for use with the limiting rod 111. The limiting holes 112 are through holes, and the limiting rod 111 is located inside the limiting holes 112.

[0029] As a technical optimization of this utility model, by setting a limiting component 11, when the pressure plate 8 drives the arc block 101 to move, the pressure plate 8 moves through the limiting hole 112 and the limiting rod 111, so as to prevent the pressure plate 8 from rotating when the screw 91 rotates, thereby enabling the arc block 101 to accurately enter the arc groove 102.

[0030] refer to Figure 2 Protective pads 12 are attached to the bottom of the arc-shaped block 101 and the top of the arc-shaped groove 102. The protective pads 12 are made of natural rubber.

[0031] As a technical optimization of this utility model, by setting a protective pad 12, the protective pad 12 protects the arc-shaped block 101 and arc-shaped groove 102 that come into contact with the wire rope, so as to avoid the arc-shaped block 101 and arc-shaped groove 102 from being worn out after long-term use, which would affect the clamping stability.

[0032] refer to Figure 2 A mounting hole 13 is provided at the center of the top of the pressure plate 8. A bearing 14 is fixed inside the mounting hole 13. The screw 91 is movably connected to the pressure plate 8 through the bearing 14.

[0033] As a technical optimization of this utility model, by setting the mounting hole 13 and the bearing 14, the screw 91 is movably installed with the pressure plate 8 through the bearing 14 and the mounting hole 13, thereby enabling the bearing 14 to ensure that the screw 91 rotates more smoothly, reducing friction and wear, and improving the service life and working efficiency of the device.

[0034] refer to Figure 2 A rotary handle 15 is fixedly connected to the top of the screw 91, and the rotary handle 15 is used to operate the screw 91.

[0035] As a technical optimization of this utility model, by setting the rotary handle 15, users can easily rotate the screw 91 without using additional tools or equipment, which improves the convenience and efficiency of operation. The mechanical design of the rotary handle 15 makes it easier to rotate the screw 91, and also improves the accuracy and efficiency of operation.

[0036] The working principle and usage process of this utility model are as follows: When the operator needs to perform a tensile test on the steel wire rope, the operator places the steel wire rope on top of the placement block 7, and then rotates the screw 91 through the rotary handle 15. The screw 91 rotates under the support of the fixing plate 92. The rotating screw 91 drives the pressure plate 8 downwards via the bearing 14. During the downward movement of the pressure plate 8, the pressure plate 8 drives the limiting rod 111 to move inside the limiting hole 112. This ensures that the limiting rod 111 and the limiting hole 112 prevent deviation from the movement trajectory of the pressure plate 8, thereby ensuring the pressure... Plate 8 moves the arc-shaped block 101 downwards, causing the arc-shaped block 101 to move the wire rope downwards. The arc-shaped block 101 moves into the arc-shaped groove 102, so that the pressure plate 8 and the placement block 7 interlock through the arc-shaped block 101 and the arc-shaped groove 102. This makes the fixing of the wire rope more stable and avoids displacement of the wire rope during stretching. After fixing, the operator starts the motor, and its output end drives the bidirectional lead screw 3 to rotate. The bidirectional lead screw 3 drives the two break members 5 to move away from each other, so that the wire rope is gradually stretched through the gradually moving break members 5, thus completing the wire rope testing work.

[0037] In summary, this testing device for elevator wire ropes, by setting up a base plate 6, a placement block 7, a pressure plate 8, and a clamping assembly 9, allows the base plate 6 to be fixedly installed with the tensile member 5. This enables the placement block 7 and the clamping assembly 9 to be installed. When fixing the wire rope, the clamping assembly 9 drives the pressure plate 8 downwards, thereby clamping and fixing the wire rope through the placement block 7. The use of this mechanical structure offers a wider range of applications compared to pneumatic clamps, reducing limitations. It solves the problem of the aforementioned equipment using pneumatic clamps to fix wire ropes, which relies heavily on the air supply system, has certain limitations, and is prone to movement during clamping and stretching when the air supply is unstable, thus affecting the testing results.
