Description

Technical Field

[0001] The utility model relates to the technical field of safety net detection, in particular to a safety net detection device. Background Art

[0002] The way to test the safety performance of safety nets is generally to conduct an impact test on the safety net. The test method is to erect a steel frame on the ground, tie the safety net's rope to the steel frame, and use the test bench to lift a 100-kilogram steel ball to a specified height. Then release the steel ball and let it impact the center of the safety net. The safety performance of the safety net is judged by observing whether it is damaged.

[0003] During the test, the safety net needs to be tied to the edge of the beam to keep the safety net in a tensioned state. In the prior art, the safety net is tied in a scattered manner, and the safety net needs to be dragged continuously during the tying process. In the later process of tensioning the safety net, it is difficult to tension it due to the friction between the tying position and the beam. Therefore, a detection device that can easily tension the safety net is needed. Utility Model Content

[0007] Preferably, reversing blocks are fixedly installed at both ends of the fixed beam, and two sets of support frames 2 are fixedly installed at the bottom end of the fixed beam.

Through such an arrangement, the traction rope 8 can drive the sliding frame 5 to move after bundling.

[0022] Steering blocks 10 are fixedly installed at both ends of the fixed beam 2, and two groups of support frames 11 are fixedly installed at the bottom end of the fixed beam 2. A winding wheel 12 is rotatably connected to the middle part of the support frame 12. The traction rope 8 is fixedly wound around the outer surface of the winding wheel 12, and a worm wheel 13 is concentrically fixedly connected to one side of the winding wheel 12. A motor 14 is fixedly installed at the bottom end of the fixed beam 2, and a worm 18 is fixedly installed at the output end of the motor 14. The worm 18 is meshed with the worm wheel 13. Such an arrangement can ensure that the traction position can be locked.

[0023] A support plate 16 is fixedly mounted on the bottom end of the fixed cross beam 2 , and the support plate 16 is rotatably connected to the worm 18 , so that the worm 18 can be supported by such an arrangement.

[0024] The inner circle of the sliding frame 5 is provided with a notch 6, and a roller 7 is rotatably connected inside the notch, and the roller 7 is rotatably connected inside the groove 3. The depth of the groove 3 and the notch 6 is greater than the diameter of the roller 7, and the outer part of the axis of the roller 7 is located inside the groove 3. This arrangement ensures that the roller 7 can rotate inside. The middle part of the roller 7 is rotatably connected to a central shaft 15, and the central shaft 15 is threadedly connected to the sliding frame 5.
