The static test equipment is mainly used to detect the tensile strength, breaking load and other static mechanical properties of the safety belt and safety rope. The common method is to apply an increasing tensile force to the sample by using a tensile testing machine, and to observe the deformation and damage of the sample. The dynamic test equipment focuses on simulating the buffering performance, impact force absorption capacity and other properties of the safety belt and safety rope under sudden situations such as falling, for example, by using a simulated falling device to make a heavy object drive the safety belt and safety rope to fall, and recording relevant data. Most existing test equipment can only perform static or dynamic tests, and it is difficult to complete comprehensive detection of the dynamic and static performance of the safety belt and safety rope on one device, which increases the cost of equipment procurement and the space occupied by the site, and also wastes time and manpower in the sample switching test process, reducing the test efficiency.

The hoisting pulley 22 is provided with a hook 23, and the hook 23 can be connected with a simulation man 24. The height of the hoisting simulation man 24 can be controlled. Meanwhile, a cross beam 29 is fixed on the bottom steel frame 11, and a support 26 is fixed on the cross beam 29. A test hanging point 25 is arranged on the support 26. The test hanging point 25 is used to meet the requirements of different types of safety belt tests on the hanging point, to ensure that the hanging point is stable during the test and does not appear loose or broken, and to provide a reliable connection point for the whole test. During the test, first, the belt is worn on the simulation man 24 according to the steps, the head of the simulation man 24 is connected with the release pulley, and then the safety rope and the buffer are connected to the belt and the test hanging point 25 respectively according to the instruction manual. If the length of the safety rope is adjustable, it needs to be adjusted to the maximum length. Then, marks are made on the edges of all the adjusting buckles of the belt.

After the simulation man 24 is stationary, the condition of the safety belt is observed and recorded, and the extension length and the displacement of the belt in the adjusting buckle are recorded.

[0032] Referring to Figures 4-5 As shown, a protection part is arranged at the bottom of the bottom steel frame 11. The protection part is composed of four groups of protection nets 27 which are connected with each other to form a protection barrier around the lower part of the test area. The protection barrier can effectively block the broken simulation man 24 during the test, and prevent it from causing harm to the personnel or equipment below. An opening and closing door 28 is arranged on one of the protection nets 27, and the test personnel can conveniently enter and exit the test area through the opening and closing door 28 to perform the preparation work before the test, the equipment inspection and maintenance after the test, and other operations.

Before the actual test, the hoisting hoist two 32 can hoist the test sample 316 of the mannequin two and the fixed lanyard one 317, which facilitates the subsequent clamping work, effectively improves the efficiency of test preparation, and enables the test to enter the formal stage faster. At the same time, a displacement part is arranged on one side of the hoisting hoist two 32 on the top steel frame 12, which includes two groups of guide rods 35 fixed on the top steel frame 12 and located on one side of the hoisting hoist two 32. One end of the two groups of guide rods 35 is connected through a fixed rod, and a hoisting hoist three 33 is fixed on the fixed rod. The hoisting hoist three 33 has a hook two 34 for flexible adjustment of the displacement of the test sample 316. An installation part one is arranged on the two groups of guide rods 35, which includes two groups of pulleys 37 arranged on the two groups of guide rods 35, and a sliding rod one 36 connected and fixed between the two groups of pulleys 37. The sliding rod one 36 can slide linearly on the two groups of guide rods 35 through the pulleys 37 at both ends. Test personnel can easily adjust the position of the sliding rod one 36 according to different test requirements to adapt to various test conditions. A 1.5-meter-long oil cylinder 38 is fixed on the sliding rod one 36. One end of the hook two 34 can be connected with the fixed rod of the installation part one. The oil cylinder 38 can provide stable pulling force during the test, and a pump station 16 is fixed on the bottom steel frame 11. The pump station 16 is connected with hydraulic actuators such as the oil cylinder 38 in the equipment through pipelines to provide stable hydraulic power for the extension and retraction of the oil cylinder 38, so that the oil cylinder 38 can exert force on the mannequin and the test sample 316 during the safety rope static test process, thereby ensuring the accuracy of the test data and the stability of the test process. The oil cylinder 38 has a lifting ring 381 at one end, which can be connected with the test sample 316 of the mannequin two and the fixed lanyard one 317, so as to exert stable and controllable force on the test sample 316, and truly simulate the stress condition in actual use, thereby providing strong support for accurate test of safety belt static performance.

[0034] In addition, a second mounting part 39 is fixedly sleeved at one end of the hydraulic cylinder 38. The second mounting part 39 has the same structure as the first mounting part. The second mounting part has a second sliding rod, which also has the same structure as the first sliding rod. A locking part is provided on the bottom surface of the second sliding rod. The locking part is used to fix the position of the second mounting part 39, ensuring that the second mounting part 39 will not move arbitrarily during the test, thus ensuring the accuracy of the test. The locking part includes a mounting box 310 fixed to the bottom surface of the second sliding rod. Two sets of symmetrically arranged cylinders 311 are fixed inside the mounting box 310. The telescopic ends of the cylinders 311 pass through the mounting box 310. A groove 312 adapted to the diameter of the telescopic ends of the cylinders 311 is provided on the mounting box 310. The groove 312 provides sufficient space and guidance for the movement of the telescopic ends of the cylinders 311, making the movement of the cylinders 311 smoother. A connecting rod 313 is connected between the telescopic ends of the two sets of cylinders 311. When the cylinders 311 are activated, the connecting rod 313 moves synchronously. Simultaneously, fixing pins 315, perpendicular to the guide rod 35, are fixed at both ends of the connecting rod 313. The guide rod 35 has multiple equally spaced through holes 351 that match the diameter of the fixing pins 315. The end of the fixing pin 315 near the guide rod 35 is tapered, allowing it to be accurately inserted into the through holes 351. Guide members 314, guiding the movement of the fixing pins 315, are fixed at both ends of the sliding rod 36. The guide members 314 have openings (not shown in the figure) on their sides, allowing the fixing pins 315 to slide and move, ensuring they can be accurately inserted into or removed from the through holes 351. This enables the mounting part 39 to be locked and unlocked on the guide rod 35, meeting the fixing requirements of different test positions and ensuring the test components maintain a stable and reliable state under various test scenarios.

[0035] To further improve the stability of the fixed position of the mounting part 39, such as Figures 8-9 As shown, a locking component 5 is fixed on the mounting box 310. After the fixing pin 315 is inserted into the through hole 351 of the guide rod 35, the locking component 5 can further lock the fixing pin 315 to prevent it from accidentally coming out and ensure the reliability of the mounting part 39. The locking assembly 5 includes a mounting base 51 fixed at the center of the surface of the mounting box 310. The mounting box 310 has a protrusion at each of its four corners. Protrusion seats 52 are fixed near both ends of the mounting box 310. The protrusion seats 52 have two protrusions on both sides. A guide shaft 53 is connected between the horizontally arranged protrusions 1 and 2. Sliding blocks 54 are connected and slidably connected to the two sets of guide shafts 53. The sliding block 54 has a fixing seat 55. A pin 56 is fixedly inserted through the fixing seat 55. The fixing pin 315 has a socket (not shown in the figure) adapted to the pin 56. When the sliding block 54 moves, the pin 56 can be inserted into the socket of the fixing pin 315 to lock the fixing pin 315.

[0036] And in the convex part one is provided with the execution part, the execution part includes the bearing is arranged in the center position of the surface of the convex part gear 57, and the driving gear 57 is arranged in the installation box 310, and the driving gear is a driving motor.

One end of the rack one 58 is fixedly connected with the right sliding block 54 and movably penetrated with the left sliding block 54. One end of the rack two 59 is fixedly connected with the left sliding block 54 and movably penetrated with the right sliding block 54. When the gear 57 rotates, the rack one 58 and the rack two 59 are driven to move linearly in opposite directions, and then the sliding blocks 54 on both sides are driven to slide along the guide shaft 53, so that the bolt 56 is inserted into or withdrawn from the insertion hole of the fixing pin 315, and the locking or unlocking of the fixing pin 315 is realized.

[0037] Working principle: After the equipment is started, the test personnel moves to the designated position by means of the track trolley 13, and prepares for clamping the safety belt and safety rope test points. The console 15 is used for controlling the operation of the overall equipment. Subsequently, the safety rope dynamic test assembly 2 starts to work, the lifting sprocket 22 lifts the simulated person 24 wearing the belt, adjusts the belt connection point to the safety rope to be higher than the test hanging point 25 (1000+50) mm, and the release point to the test hanging point 25 horizontal distance not more than 300mm position, release the simulated person 24, record the safety belt impact force peak value in the suspended state, after the simulated person 24 is static, observe and record the safety belt situation, measure the length and the displacement of the belt in the adjusting buckle. Then unload the belt, replace the safety rope and buffer, repeat the above steps, and test and record the data again. At the same time, the protection part at the bottom of the bottom steel frame 11, the protection barrier composed of four groups of protection nets 27, can effectively block the damage to the lower part of the simulated person 24 in the test. The test personnel enters and exits the test area through the opening and closing door 28 to carry out preparation and maintenance work.

[0038] At the same time, the safety rope static test assembly 3 is put into operation, the lifting sprocket 32 lifts the test sample 316 of the simulated person 2 and the fixed belt 1 317, and facilitates subsequent clamping. The lifting sprocket 33 of the displacement part cooperates with the hook 2 34, so that the position of the test sample 316 can be flexibly adjusted. The sliding rod 1 36 of the installation part 1 slides on the guide rod 35 by means of the pulley 37, so as to meet the position requirements of different test conditions. The pump station 16 provides hydraulic power for the oil cylinder 38, the oil cylinder 38 is connected with the simulated person 2 and the test sample 316 through the lifting ring 381, and a stable controllable force is applied to the simulated person 2 and the test sample 316, so as to simulate the actual stress condition and test the static performance of the safety belt.

[0039] When the position of the second mounting part 39 needs to be fixed, the locking part works. The cylinder 311 is actuated to drive the connecting rod 313 to move, so that the fixing pin 315 is inserted into the through hole 351 of the guide rod 35, and the second mounting part 39 is preliminarily fixed. In order to further improve the fixing stability, the locking assembly 5 is started, the driving motor drives the gear 57 to rotate, the rack one 58 and the rack two 59 engaged with the gear 57 move in opposite straight lines, the sliding block 54 is driven to slide along the guide shaft 53, the bolt 56 is inserted into the insertion hole of the fixing pin 315, and the fixing pin 315 is locked again to prevent it from being accidentally pulled out, so that the position of the second mounting part 39 is stable during the test, and the accuracy of the static test is ensured.

[0040] The dynamic test and the static test can be performed in sequence or separately according to requirements. The dynamic test simulates the performance of the safety belt in a dynamic scene such as falling, and the static test is for static stress conditions. The protection part always ensures safety under the test area, the console 15 controls the operation of the assembly, and the track trolley 13 assists the test personnel to operate. Through the joint work of each component, the dynamic and static performance of the safety belt and the safety rope is tested, and accurate impact force peak, stretching length, and lacing displacement data are obtained, which provides a basis for performance evaluation of the safety belt and the safety rope. After the test is completed, each component can be reset according to the operation process, so as to perform the next test.
