Description

Technical Field

[0001] This utility model relates to the field of mechanical testing equipment technology, and in particular to a performance testing device for a rigid guide rail self-locking device. Background Technology

[0002] Rigid guide rails are currently widely used to guide and support moving parts. In the event of an accident, such as a power failure or component damage, these devices may cause the moving parts to slip or move uncontrollably, leading to serious safety accidents. As a safety protection mechanism, the self-locking device of a rigid guide rail can quickly lock the moving parts in an emergency, reducing the probability of accidents and ensuring the safety of personnel and equipment. Therefore, testing the performance of the rigid guide rail self-locking device is crucial to ensuring the safe operation of these devices.

[0003] Related technology can be found in Chinese Patent No. CN216559655U, which discloses a testing device for a guide rail self-locking device. The device includes a guide rail for mounting the self-locking device; a support frame for supporting the guide rail to fix it vertically; a drive assembly for providing tension to the self-locking device; and a tension sensor connected to the self-locking device and the drive assembly to measure the tension value between them. When testing the self-locking device, the host computer controls the drive assembly and the tension sensor to start. The drive assembly pulls the self-locking device downwards, and the tension sensor measures the maximum tension value of the self-locking device moving on the guide rail. By comparing the maximum tension value with the standard threshold of the self-locking device, it can be determined whether the locking performance of the self-locking device meets the standard. This testing device is simple to operate and can accurately test the performance of the self-locking device.

[0004] Regarding the aforementioned technologies, the testing equipment has limited testing functions. During the testing process, it can only perform performance testing on the forward movement of the self-locking device, failing to fully cover various performance requirements of the self-locking device in actual use scenarios, such as the reverse braking effect of the self-locking device. It also cannot achieve integrated testing of multiple performance aspects, resulting in a decrease in the accuracy of the self-locking device performance test. Utility Model Content

[0005] To improve the accuracy of self-locking device performance testing, this application provides a rigid guide rail self-locking device performance testing device.

[0006] This application provides a performance testing device for a rigid guide rail self-locking device, which adopts the following technical solution:

[0007] A performance testing device for a rigid guide rail self-locking device includes a test frame, a rigid guide rail at the upper end of the test frame, the rigid guide rail being detachably connected to the test frame, a counterweight on one side of the rigid guide rail being slidably connected to the rigid guide rail, a self-locking device between the rigid guide rail and the counterweight being used to lock the counterweight, and a release device at the upper end of the counterweight being used to release the counterweight from multiple dimensions.

[0008] By adopting the above technical solution, the test frame and rigid guide rail are detachably connected, which facilitates the adjustment of the position and tilt angle of the rigid guide rail, and also facilitates the assembly and maintenance of the device. The sliding connection between the counterweight and the rigid guide rail facilitates the simulation of dynamic working conditions in the usage scenario. The connection between the self-locking device and the counterweight ensures the effective locking of the counterweight, thereby verifying the functional reliability of the self-locking device. The release device releases the counterweight from multiple directions, making the test conditions more diverse, which is conducive to demonstrating the performance of the self-locking device under different conditions and improving the accuracy of the self-locking device performance test.

[0009] Optionally, the release device includes a connecting rope, a lifting ring, and a hook. The connecting rope is fixed to the upper end of the test frame, the hook is fixed to the lower end of the connecting rope, and the lifting ring is fixed to the upper end of the counterweight. The lifting ring and the hook are detachably connected.

[0010] By adopting the above technical solution, the connecting rope is fixed to the upper end of the test frame, ensuring the stability of the entire device. The detachable connection design of the hook and the lifting ring allows the counterweight to be quickly released from the suspension state when needed, thereby simulating the sudden load situation of the self-locking device in actual use and improving the reliability and accuracy of the test.

[0011] Optionally, the release device also includes a guide rope, a pulley, and a test weight. The guide rope is fixed to the upper end of the test frame, the test weight is fixed to the lower end of the guide rope, the pulley is located on one side of the counterweight, the pulley and the counterweight are detachably connected in the lateral direction, and the pulley is tumblingly connected to the guide rope along the length of the guide rope.

[0012] By adopting the above technical solution, the guide rope is fixed to the upper end of the test frame and the test weight is fixed to the lower end of the guide rope. This structural design allows the weight of the test weight to be transmitted through the guide rope, thereby providing a stable power source for the release of the counterweight and ensuring the controllability of the release process. The pulley and the counterweight are detachably connected in the lateral direction, so that the pulley applies a backward pulling force to the counterweight, thereby improving the flexibility of the testing device.

[0013] Optionally, the test fixture includes a base and several support rods, with the support rods located at the upper end of the base and all of the support rods being fixed perpendicularly to the base.

[0014] By adopting the above technical solution, the support rod is vertically fixed to the base, thus forming a stable structural frame. This design allows the test frame to stably support the rigid guide rail and counterweight, ensuring that the entire testing device maintains good stability during operation, effectively reducing the probability of structural tilting due to instability of the test frame structure, and improving the stability of the device.

[0015] Optionally, the support rod has several threaded holes, the rigid guide rail has several bolts, and a nut is provided on one side of the bolt. The nut and the bolt correspond one-to-one, and the bolt passes through any threaded hole and is threadedly connected to the nut.

[0016] By adopting the above technical solution, the support rod of the test frame has several threaded holes, and the rigid guide rail has several bolts. The bolts and nuts cooperate to achieve a detachable connection between the rigid guide rail and the test frame. This method allows the rigid guide rail to be flexibly adjusted in installation position according to actual needs, and also allows for adjustment of the tilt angle of the rigid guide rail, improving the flexibility of the testing device. At the same time, the bolt and nut connection method is simple to operate, easy to assemble and maintain, and effectively improves the ease of use of the testing device.

[0017] Optionally, an eccentric lifting ring is fixed to the upper end of the counterweight, and a force sensor is fixed between the eccentric lifting ring and the lifting ring. The force sensor is used to detect the force data and control the test load.

[0018] By adopting the above technical solution, the eccentric lifting ring allows the counterweight to generate tilting or eccentric torque during release, thereby simulating asymmetrical load conditions that may exist in actual working conditions and improving the testing accuracy of the detection device. The force sensor can monitor and record the force data between the counterweight and the lifting ring in real time, providing quantitative basis for evaluating the performance of the self-locking device and ensuring the accuracy and reliability of the test results.

[0019] Optionally, a buffer element is fixed between the lifting ring and the self-locking device. The buffer element is made of elastic material to reduce the impact force on the buffer element.

[0020] By adopting the above technical solution, the buffer effectively reduces the impact force of the counterweight on the self-locking device during the release process, protects the self-locking device from damage, and further extends the service life of the self-locking device.

[0021] Optionally, a steering mechanism is fixed on the test fixture to allow the self-locking device to slide on the guide rail.

[0022] By adopting the above technical solution, the steering mechanism effectively changes the direction of movement of the self-locking device on the rigid guide rail, thereby simulating more complex usage scenarios, making the self-locking device move more smoothly during the test, and improving the stability of the device during operation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The release device releases the counterweight from multiple directions, diversifying the test conditions and helping to demonstrate the performance of the self-locking device under different conditions, thereby improving the accuracy of the self-locking device performance test;

[0025] 2. The steering mechanism effectively changes the direction of movement of the self-locking device on the rigid guide rail, thereby simulating more complex usage scenarios, making the self-locking device move more smoothly during testing, and improving the stability of the device during operation.

[0026] 3. Bolts and nuts are used to achieve a detachable connection between the rigid guide rail and the test frame. This method allows the rigid guide rail to be flexibly adjusted in installation position according to actual needs, and also allows for adjustment of the tilt angle of the rigid guide rail, thus improving the flexibility of the testing device.

Detailed Implementation

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a device for testing the performance of a rigid guide rail self-locking device. Example

[0032] Reference Figure 1 A performance testing device for a rigid guide rail self-locking device includes a test frame 1. The test frame 1 includes a base 14 and several support rods 15. The support rods 15 are located at the upper end of the base 14 and are all vertically fixed to the base 14, thus forming a stable structural frame. This design allows the test frame 1 to stably support the rigid guide rail 11 and the counterweight 13, ensuring that the entire testing device maintains good stability during operation. It effectively reduces the probability of structural tilting due to instability of the test frame 1 and improves the stability of the device.

[0033] Reference Figure 1 The upper end of the test frame 1 is provided with a rigid guide rail 11. The support rod 15 has several threaded holes 113. Several bolts 111 are provided on the rigid guide rail 11. A nut 112 is provided on one side of the bolt 111. The nut 112 corresponds to the bolt 111. The bolt 111 passes through any threaded hole 113 and is threadedly connected to the nut 112. The bolt 111 and the nut 112 cooperate to realize the detachable connection between the rigid guide rail 11 and the test frame 1. The connection method is simple to operate, easy to assemble and maintain, effectively improving the ease of use of the testing device. It also allows the rigid guide rail 11 to be flexibly adjusted in installation position according to actual needs through the threaded holes 113. In addition, the tilt angle of the rigid guide rail 11 can be adjusted, which improves the flexibility of the testing device.

[0034] Reference Figure 1 A counterweight 13 is provided on one side of the rigid guide rail 11. The counterweight 13 is slidably connected to the rigid guide rail 11 to facilitate the simulation of dynamic working conditions in the usage scenario. The self-locking device 12 is located between the rigid guide rail 11 and the counterweight 13. The connection between the self-locking device 12 and the counterweight 13 ensures the effective locking of the counterweight 13, thereby verifying the functional reliability of the self-locking device 12.

[0035] Reference Figure 1 and Figure 2 The upper end of the counterweight 13 is equipped with a release device, which includes a connecting rope, a guide rope 131, a pulley 132, a test weight 133, a lifting ring 135, and a hook 136. The connecting rope is fixed to the upper end of the test frame 1 to ensure the stability of the entire device. The hook 136 is fixed to the lower end of the connecting rope, and the lifting ring 135 is fixed to the upper end of the counterweight 13. The lifting ring 135 and the hook 136 are detachably connected, so that the counterweight 13 can quickly detach from the suspension state when needed, thereby simulating the sudden load situation of the self-locking device 12 in actual use and improving the reliability and accuracy of the test.

[0036] Reference Figure 1 and Figure 2 The guide rope 131 is fixed to the upper end of the test frame 1. The pulley 132 is located on one side of the guide rope 131 and is rolled vertically connected to the guide rope 131. The pulley 132 is detachably connected to the counterweight 13 horizontally. The test weight 133 is fixed to the lower end of the guide rope 131, so that the weight of the test weight 133 is transmitted through the guide rope 131, thereby providing a stable power source for the release of the counterweight 13 and ensuring the controllability of the release process. The pulley 132 is detachably connected to the counterweight 13 horizontally, so that the pulley 132 applies a backward pulling force to the counterweight 13, thereby improving the flexibility of the testing device.

[0037] Reference Figure 1 and Figure 2An eccentric lifting ring 137 is fixed to the upper end of the counterweight 13. The eccentric lifting ring 137 allows the counterweight 13 to generate tilting or eccentric torque during release, thereby simulating asymmetrical load conditions that may exist in actual working conditions and improving the testing accuracy of the detection device. A force sensor 134 is fixed between the eccentric lifting ring 137 and the lifting ring 135. The force sensor 134 can monitor and record the force data between the counterweight 13 and the lifting ring 135 in real time, providing a quantitative basis for evaluating the performance of the self-locking device 12 and ensuring the accuracy and reliability of the test results.

[0038] Reference Figure 1 and Figure 2 A steering mechanism 17 is fixed on the test frame 1. The setting of the steering mechanism 17 effectively changes the movement direction of the self-locking device 12 on the rigid guide rail 11, thereby simulating more complex usage scenarios of the self-locking device 12, making the self-locking device 12 move more smoothly during the test, and improving the stability of the device during operation.

[0039] Reference Figure 1 and Figure 2 A buffer 16 is fixed between the lifting ring 135 and the self-locking device 12. The buffer 16 is made of elastic material, which effectively reduces the impact force of the counterweight 13 on the self-locking device 12 during the release process, protects the self-locking device 12 from damage, and further extends the service life of the self-locking device 12.

[0040] The implementation principle of the rigid guide rail self-locking device according to the present application embodiment is as follows: the hook 136 and the hanging ring 135 are detachable. During the test, the hook 136 and the hanging ring 135 are separated, so that the counterweight 13 quickly leaves the suspension state under the action of gravity, simulating the situation where the self-locking device 12 suddenly encounters a load. At the same time, the pulley 132 applies a backward pulling force to the counterweight 13 under the action of the test weight 133. The performance of the self-locking device 12 in the inclined state is tested by adjusting the angle of the rigid guide rail 11. The performance of the self-locking device 12 is tested from multiple dimensions, thereby improving the accuracy of the performance testing device.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
