Technical Field
[0001] This utility model relates to the field of safety protection device testing equipment technology, and in particular to a multifunctional safety protection device performance testing equipment. Background Technology
[0002] In the process of rapid development of modern industry, with the continuous deepening of intelligence and automation, the scale of industrial production is expanding day by day, and the working environment is becoming more and more complex and diverse. At the same time, industrial safety standards are constantly being improved, and the demand for performance testing of safety protection devices, as the last line of defense to protect the lives of workers, is showing an explosive growth trend.
[0003] Nowadays, tensile testing machines are widely used to test the performance of safety protection devices. These devices, based on mechanical principles, utilize high-precision sensors and servo motor systems to accurately simulate the tensile loads that safety protection devices endure under extreme working conditions. The tensile testing machine gradually increases the tensile force on the safety protection device at a set speed. During this process, the system records key indicators such as tensile force and deformation, and generates a detailed test report, providing a scientific and accurate basis for determining whether the safety protection device meets safety standards.
[0004] Regarding the aforementioned technologies, tensile testing machines can only test a single safety protection device. Since the structural design, material properties, and safety standard requirements of safety protection devices vary, each type of device needs to be equipped with a dedicated testing machine. In the actual testing process, operators need to frequently switch between different testing devices, not only to be familiar with the operating procedures of each device, but also to frequently adjust the test parameters, resulting in a lengthy and cumbersome testing process. Utility Model Content
[0005] In order to improve the testing efficiency of safety protection devices, this application provides a multifunctional safety protection device performance testing device.
[0006] This application provides a multifunctional safety protection device performance testing equipment, which adopts the following technical solution:
[0007] A multifunctional safety protection device performance testing device includes a test frame. The upper end of the test frame is equipped with a safety belt testing component for testing the performance of safety belts. Below the safety belt testing component is a self-locking device testing component for testing the performance of self-locking devices. To one side of the self-locking device testing component is a speed differential controller testing component for testing the performance of speed differential controllers. The upper end of the test frame also has a foot spike testing component for testing foot spikes. The lower end of the test frame has a winch testing component for testing winches. One side of the test frame has a vertical pole, which is detachably connected to the test frame and is used to test the performance of mountaineering foot clips. Both ends of the vertical pole have connectors for connecting the vertical pole and the test frame.
[0008] By adopting the above technical solutions, the safety belt testing component tests the performance of the safety belt, the self-locking device testing component tests the performance of the self-locking device, the speed difference controller component tests the performance of the speed difference controller, the foot spike testing component tests the performance of the foot spike, and the winch testing component tests the winch. The upright and the test frame are detachably connected by connectors, which facilitates installation and disassembly. The tester wears the climbing buckle to be tested and then climbs along the upright to test the performance of the climbing buckle. The test frame can test multiple safety protection devices at the same time, reducing the time required for testing and thus improving the testing efficiency of the testing equipment.
[0009] Optionally, the connector includes a connecting plate, several clamping plates, several bolts, and several nuts. The connecting plate is located on one side of the test frame. Two clamping plates are provided on the side of the connecting plate away from the test frame. The two clamping plates cooperate to clamp the upright. Several clamping plates are located on the side of the test frame away from the connecting plate, and the clamping plates are evenly placed in the horizontal direction. Several bolts pass through the clamping plates and the connecting plate in sequence. Nuts correspond one-to-one with the bolts. The nuts are located at the ends of the bolts away from the clamping plates, and the bolts and nuts are threadedly connected.
[0010] By adopting the above technical solution, the connecting plate and the clamping plate are locked onto the test frame through the threaded connection of nuts and bolts, which improves the stability of the connection. At the same time, it is convenient for staff to disassemble and install the upright. The two clamping plates work together to lock the upright out, reducing the probability of the upright shifting during the test and improving the safety of the test.
[0011] Optionally, the two plates are arranged along the length of the connecting plate, and the side of the two plates that are close to each other has an arc-shaped surface.
[0012] By adopting the above technical solution, the two clamping plates clamp the two sides of the column upright respectively, ensuring that the upright is subjected to uniform force when clamped, reducing the probability of loosening caused by uneven force. The arc-shaped surface fits against the outer wall of the upright, increasing the contact area with the upright and improving the stability of the clamping plate in positioning the upright.
[0013] Optionally, the diameter of the upright gradually decreases from bottom to top.
[0014] By adopting the above technical solution, the design of the pole with a gradually decreasing diameter from bottom to top simulates the changes in the pole body in actual use scenarios, thereby more accurately detecting the gripping performance of the climbing clips on poles of different diameters. This design makes the test results closer to actual working conditions and improves the reliability and accuracy of the test.
[0015] Optionally, the foot spike testing assembly includes a test plate and a connector. The test plate is located at the upper end of the test frame and is detachably connected to the test frame. Several through holes are opened on the surface of the test plate. The connector is located at the upper end of the test plate and is hooked to the test plate.
[0016] By adopting the above technical solution, the test board and the test frame are connected by a snap-fit mechanism, which facilitates the adjustment of the test board's position and improves the flexibility of the testing device. The connector is attached to the test board, which improves the connection stability between the test board and the test frame. The foot nail to be tested is inserted into the through hole, and one end of the foot nail is attached to the test dummy. The test dummy is released and descends under the action of gravity. The accuracy of the test is then observed.
[0017] Optionally, the connector includes a connecting block, a steel wire rope, two hooks, and two hanging rings. The connecting block is located at the upper end of the test frame. The steel wire rope passes through the connecting block. The hooks are fixed at both ends of the steel wire rope. The hanging rings are fixed at both ends of the test plate. The hooks and hanging rings correspond one-to-one, and the hooks are engaged with their corresponding hanging rings.
[0018] By adopting the above technical solution, the connecting block provides a connection fulcrum for the first wire rope. The first wire rope is detachably connected to the test plate through hooks and hanging rings, which strengthens the connection stability between the test plate and the test frame, while reducing the probability of test plate vibration during the test and improving the stability of the test device.
[0019] Optionally, several through holes are arranged evenly along the vertical direction, and each through hole has a different size.
[0020] By adopting the above technical solution, the test plate of the foot nail detection component can adapt to the detection requirements of different specifications of foot nails by using different through hole sizes. The test plate can provide accurate detection positions for foot nails of various sizes, effectively improving the flexibility of the detection device.
[0021] Optionally, the winch testing assembly includes a winch, a second steel wire rope, and a test weight. The winch is located on one side of the test frame, the second steel wire rope is fixed inside the winch, and the test weight is fixed at the end of the second steel wire rope away from the winch.
[0022] By adopting the above technical solution, the test weight is released and moves downward under the action of gravity. The downward movement of the test weight applies a certain tension to the steel wire rope, thereby checking whether the winch is operating normally and improving the convenience of the testing equipment.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The safety belt testing component tests the performance of the safety belt; the self-locking device testing component tests the performance of the self-locking device; the speed differential control device testing component tests the performance of the speed differential control device; the foot spike testing component tests the performance of the foot spikes; and the winch testing component tests the winch. The tester wears the climbing buckle to be tested and then climbs along the upright to test the performance of the climbing buckle. The test frame can test multiple safety protection devices at once, reducing the time required for testing and thus improving the testing efficiency of the testing equipment.
[0025] 2. The different through-hole sizes allow the test plate of the foot nail detection component to adapt to the testing needs of foot nails of different specifications. The test plate can provide accurate detection positions for foot nails of various sizes, effectively improving the flexibility of the detection device.
[0026] 3. The design of the pole with its diameter gradually decreasing from bottom to top simulates the changes in the pole body in actual use scenarios, thereby more accurately detecting the gripping performance of the climbing clips on poles of different diameters.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.
[0032] This application discloses a multifunctional safety protection device performance testing equipment. Example
[0033] Reference Figure 1 and Figure 2 A multifunctional safety protection device performance testing device includes a test frame 1. A seat belt testing component 11 is located at the upper end of the test frame 1, used to test the performance of seat belts. A foot spike testing component 14 is located below the seat belt testing component 11. The foot spike testing component 14 includes a test plate 141 and connecting parts. The test plate 141 is located at the upper end of the test frame 1 and is detachably connected to the test frame 1. Adjusting the position of the test plate 141 improves the flexibility of the testing device. Several openings are formed on the surface of the test plate 141. The test plate 141 has several through holes 146 arranged vertically and evenly, with each through hole 146 being of a different size. During testing, the foot nail to be tested is inserted into the through hole 146, allowing the test plate 141 to adapt to the testing requirements of foot nails of different specifications. The test plate 141 can provide precise testing positions for foot nails of various sizes, effectively improving the flexibility of the testing device. During testing, one end of the foot nail is attached to the test dummy, which descends under the action of gravity. The test dummy is then observed to see if the foot nail is loose, simulating a real-world practical scenario for foot nail testing and improving the accuracy of the testing device.
[0034] Reference Figure 2The connector is located at the upper end of the test plate 141 and is hooked to the test plate 141. The connector includes a connecting block 142, a steel wire rope 143, two hooks 144 and two hanging rings 145. The connecting block 142 is located at the upper end of the test frame 1. The steel wire rope 143 passes through the connecting block 142 and the connecting block 142 provides a connection fulcrum for the steel wire rope 143. The hooks 144 are fixed at both ends of the steel wire rope 143 and the hanging rings 145 are fixed at both ends of the test plate 141. The hooks 144 and hanging rings 145 correspond one-to-one and are hooked to the corresponding hanging rings 145. The steel wire rope 143 is detachably connected to the test plate 141 through the hooks 144 and hanging rings 145, which strengthens the connection stability between the test plate 141 and the test frame 1, and at the same time reduces the probability of vibration of the test plate 141 during the test, thereby improving the stability of the test device.
[0035] Reference Figure 1 Below the foot spike detection component 14 is a self-locking device detection component 12, which is used to detect the self-locking device. On one side of the self-locking device detection component 12 is a speed difference self-controller detection component 13, which is used to detect the performance of the speed difference self-controller. Multiple safety protection devices can be tested simultaneously on the test frame 1, reducing test time and improving the efficiency of safety device testing.
[0036] Reference Figure 3 The test frame 1 has a vertical pole 16 on one side. The vertical pole 16 is set in the vertical direction. The tester wears the carabiner to be tested and climbs along the vertical pole 16 to test the performance of the carabiner. The diameter of the vertical pole 16 gradually decreases from bottom to top, simulating the changes of the pole in the actual use scenario. This allows for a more accurate test of the grip performance of the carabiner on poles of different diameters, as well as the flexibility of the carabiner in use. This design makes the test results closer to the actual working conditions and improves the reliability and accuracy of the test.
[0037] Reference Figure 3Two connectors are provided between the upright 16 and the test frame 1. The two connectors are located at the two ends of the upright 16. The connectors include a connecting plate 161, several clamping plates 162, several bolts 163, and several nuts 164. The connecting plate 161 is located on one side of the test frame 1, and the clamping plates 162 are located on the side of the test frame 1 away from the connecting plate 161. The clamping plates 162 are evenly placed horizontally. The bolts 163 pass through the clamping plates 162 and the connecting plate 161 in sequence. The nuts 164 correspond one-to-one with the bolts 163. 4 is located at the end of bolt 163 away from clamping plate 162, and bolt 163 is threadedly connected to nut 164, so that connecting plate 161 and clamping plate 162 are engaged and locked onto test frame 1, improving connection stability and facilitating disassembly and installation of upright 16 by personnel. Two clamping plates 166 are provided on the side of connecting plate 161 away from test frame 1, located on both sides of upright 16. The two clamping plates 166 cooperate to hold upright 16, reducing the probability of upright 16 shifting during testing and improving testing stability. An arc-shaped surface 165 is provided on the side of the two clamping plates 166 that is close to each other. The arc-shaped surface 165 fits against the outer wall of upright 16, increasing the contact area with upright 16 and improving the stability of clamping plate 166 in positioning upright 16.
[0038] Reference Figure 1 The lower end of the upright 16 is provided with a winch detection assembly 15, which includes a winch, a second steel wire rope 152, and a test weight 151. The winch is located on one side of the test frame 1, the second steel wire rope 152 is fixed inside the winch, and the test weight 151 is fixed at the end of the second steel wire rope 152 away from the winch. When the test weight 151 is released, it moves downward under the action of gravity, and the test weight 151 applies a certain tension to the second steel wire rope 152 to detect whether the winch is operating normally, thereby improving the convenience of the detection equipment.
[0039] The implementation principle of the multifunctional safety protection device performance testing equipment in this application embodiment is as follows: the tester wears the climbing buckle to be tested and climbs along the upright 16 to simulate a real use scenario and test the performance of the climbing buckle. The upper end of the test frame 1 is equipped with a safety belt testing component 11 for testing the performance of the safety belt, as well as a self-locking device testing component 12 for testing the performance of the self-locking device, a speed difference self-controller testing component 13 for testing the performance of the speed difference self-controller, a foot spike testing component 14 for testing the performance of the foot spikes, and a winch testing component 15 for testing the performance of the winch.
