[0023] EMBODIMENT

[0024] The following will be combined with the drawings Figure 1 - the drawings Figure 6The application is further described in detail. A multi-station safety belt static load test device, comprising a placing assembly 1 placed on the ground, a controller 2 fixedly installed on the placing assembly 1, an adjusting assembly 4 rotatably installed at one end of the placing assembly 1 away from the ground for adjusting the angle of the safety belt tension, a plurality of limiting assemblies 3 fixedly installed on the adjusting assembly 4 away from the placing assembly 1, the adjusting assembly 4 comprising a telescopic test assembly 41, the test assembly 41 comprising a wire fixing part 411, a plurality of pull ropes 412 fixedly connected around the wire fixing part 411, a tension sensor 413 fixedly connected to the pull rope 412 for tension test, the limiting assembly 3 for limiting the pull rope 412, the placing assembly 1 comprising a middle disc 13, a plurality of rotating assemblies 14 for rotating the pull rope 412 rotatably installed on the middle disc 13, the rotating assembly 14 fixedly connected to the pull rope 412, the rotating assembly 14 comprising a first motor 141 fixed on the bottom disc, an output end of the first motor 141 fixedly connected to a rotating shaft 142, the rotating shaft 142 fixedly installed with a rotating disc 143 at one end away from the first motor 141, the rotating disc 143 fixedly installed with a simulated human body 144 for static load test, the simulated human body 144 fixedly connected with a hook 145 at one end away from the rotating disc 143, the pull rope 412 fixedly connected with a test hook 414 at the bottom, the test hook 414 used in cooperation with the hook 145, a plurality of isolation plates 12 for separating the rotating assemblies 14 fixedly installed on the top of the middle disc 13, a column body fixedly installed in the middle of the middle disc 13, an installation groove 11 provided in the top of the column body for connecting the placing assembly 1 and the adjusting assembly 4, the adjusting assembly 4 further comprising a second motor 42 fixed in the installation groove 11, an output end of the second motor 42 fixedly connected to a top disc 44, the top disc 44 provided with a straight slot 45 for the pull rope 412 to move at a position close to the limiting assembly 3, a hydraulic push rod 46 fixedly installed at the center position of the top disc 44, the extension end of the hydraulic push rod 46 fixedly installed with the wire fixing part 411, the limiting assembly 3 comprising a micro motor 31 fixed on the top disc 44, an output end of the micro motor 31 fixedly connected with a lead screw 35, the lead screw 35 threadedly connected with a movable block 32 movably installed thereon, a plurality of sliding rails 33 fixedly installed on the top disc 44, the movable block 32 limitedly moving on the sliding rails 33, a wire penetrating hole 34 provided at the center position of the movable block 32 for the pull rope 412 to penetrate, an independent controller 43 fixedly installed on the top disc 44 at a position close to the limiting assembly 3, the independent controller 43 electrically connected with the control box of the micro motor 31, the movable block 32 made of stainless steel.

[0025] Wherein, since the rotation of the second motor 42 can directly bring the top plate 44 to rotate relative to the placing assembly 1, and the rotation of the micro motor 31 can bring the movable block 32 to slide on the slide rail 33, since the pull ropes 412 are all penetrated and limited in the threading opening 34, the rotation of the second motor 42 and the micro motor 31 can directly adjust the pulling angle of the top of the simulated human body 144, greatly improving the operability of the multi-station safety belt static load test device.

[0026] Wherein, since the fixed wire part 411 is fixedly installed on the top of the hydraulic push rod 46, and the plurality of pull ropes 412 are fixedly connected around the fixed wire part 411, when the hydraulic push rod 46 is stretched and retracted, the pull rope 412 pulls the simulated human body 144, and the tension sensor 413 detects the size of the tension, thereby completing the static load test of the safety belt rope.

[0027] Wherein, since the rotating disc 143 is fixedly installed on the rotating shaft 142, and the simulated human body 144 is fixedly installed on the rotating disc 143, when the first motor 141 rotates, the simulated human body 144 also rotates, and the safety belt rope and the pull rope 412 fixed on the top of the simulated human body 144 are also rotated, and the extension of the hydraulic push rod 46 can test the static load tension of the safety belt rope.

[0028] Wherein, since the controller 2 and the electronic devices inside the multi-station safety belt static load test device are electrically connected, the user can directly control the electronic devices inside the multi-station safety belt static load test device by controlling the controller 2, greatly improving the intelligence of the multi-station safety belt static load test device.

[0029] Wherein, the hydraulic push rod 46 in the utility model is only one, and the user can set multiple hydraulic push rods 46 for the pull rope 412 according to the specific use, so as to perform static load test on the safety belt rope of multiple stations one by one.

[0030] The working principle of the utility model is described as follows: the various mechanical structures inside the multi-station safety belt static load testing device are fixed by threads if not explicitly stated, and the bolt connections are appropriately hidden in the drawing to enable more intuitive observation of the professional technical features. When the multi-station safety belt static load testing device is in use, the user binds the safety belt that needs to be subjected to static load testing on the simulated human body 144, and hooks 145 and test hooks 414 are hooked with each other. At this time, the user can adjust the tension angle of the simulated human body 144 according to the specific testing conditions, and the user can directly control the starting of the second motor 42 through the controller 2. The started second motor 42 slightly rotates the top disc 44 to adjust the upward pulling angle of the test hook 414. The user can also start the micro motor 31 through the controller 2 and the independent controller 43. The started micro motor 31 rotates the screw rod 35, and the movable block 32 directly rotates on the slide rail 33 at this time. Since the pull rope 412 is located in the threading opening 34 of the movable block 32, the movement of the movable block 32 can also adjust the upward pulling angle of the test hook 414. When the upward pulling angle of the test hook 414 is adjusted, the user only needs to start the hydraulic push rod 46. At this time, the upward pulling hydraulic push rod 46 pulls the safety belt rope body bound on the simulated human body 144, and the tension sensor 413 tests the tensile strength of the pull rope 412 and the safety belt rope body. When the user needs to rotate the pull rope 412 and the safety belt rope body, the user only needs to start the first motor 141 through the controller 2. The started first motor 141 directly rotates the simulated human body 144, and the rotated simulated human body 144 rotates the pull rope 412 and the safety belt rope body. At this time, the user starts the hydraulic push rod 46 to test the tensile strength of the rotated pull rope 412 and the safety belt rope body. In this way, the multi-station safety belt static load testing device can perform multi-angle pulling static load testing on the safety belt rope and perform static load testing on the safety belt rope after rotation under the premise of multi-angle pulling static load testing on the safety belt rope, greatly improving the practicality of the multi-station safety belt static load testing device.

[0031] The technical features of the above embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
