[0026] In the above technical scheme, the problem that there is a need to move the position of the device is taken into consideration. In order to solve such a problem, the specific operation is as follows: by turning the handle 14, the turntable 25 is driven to rotate, thereby driving the screw rod 24 to rotate, and at the same time, the moving block 21 is driven to move at the bottom of the placement plate 1, and the cylinder 22 moves inside it. Under the cooperation of the first connecting block 15, the first connecting rod 16, the second connecting block 17, the third connecting block 18, the second connecting rod 19, the connecting column 20, the slide groove 26 and the limit block, the support plate 12 is driven to move downward and slowly approach the ground. The handle 14 is continued to be turned to lift the placement plate 1 and make the roller 11 leave the ground, so that the entire device can be supported and fixed. When it needs to be moved, only the handle 14 needs to be turned in the opposite direction to make the support plate 12 slowly leave the ground, and the device is put down to make the roller 11 contact with the ground, so that the device can be moved and the position can be adjusted. It is simple, convenient and fast.
[0027] Reference Figure 1 and Figure 4 In a preferred embodiment, the limiting component includes a fixed block 7, which is fixedly connected to the top of the positioning block 6 at an equal distance, and a fixed rod 27 is rotatably connected between one side of the fixed block 7, and a card plate 8 is fixedly connected to the outer side of the fixed rod 27. A second motor 9 is provided on one side of the fixed block 7, and one end of the output shaft of the second motor 9 is fixedly connected to one end of the fixed rod 27, and a slot is provided on one side of the card plate 8; a speed sensor is provided on the top of the inner wall of the through slot in the positioning block 6. When the maintenance personnel fall dangerously, the safety rope will drop rapidly with the maintenance personnel. At this time, the speed sensor located in the through slot detects the abnormal movement of the safety rope, and at the same time controls the second motor 9 to drive the fixed rod 27 to rotate, so that the card plate 8 swings downward, so that the slot of the card plate 8 presses against the outer side of the safety rope, presses the safety rope, and prevents the safety rope from continuing to slide.
[0028] Working principle: When in use, first, move the device to the working area through the roller 11, reel the safety rope into the reel 4, pass one end through the through slot of the positioning block 6, and then fix the safety rope to the maintenance personnel. Turn the handle 14 to drive the turntable 25 to rotate, thereby driving the screw rod 24 to rotate, and at the same time, it will also drive the moving block 21 to move at the bottom of the placement plate 1, and the cylinder 22 moves inside it. Under the cooperation of the first connecting block 15, the first connecting rod 16, the second connecting block 17, the third connecting block 18, the second connecting rod 19, the connecting column 20, the slide groove 26 and the limit block, the support plate 12 is driven to move downward and slowly approach the ground. Continue to turn the handle 14 to lift the placement plate 1 to make the roller 11 off the ground, and the entire device can be supported and fixed. When needed When moving, it is only necessary to rotate the handle 14 in the opposite direction to slowly lift the support plate 12 off the ground, and lower the device so that the roller 11 contacts the ground, and the device can be moved. When the maintenance personnel fall in danger, the safety rope will drop rapidly with the maintenance personnel. At this time, the speed sensor located in the through groove detects the abnormal movement of the safety rope and controls the first motor 5 and the second motor 9 at the same time. The first motor 5 controls the winding drum 4 to stop rotating, so that the safety rope stops, and then the second motor 9 drives the fixing rod 27 to rotate, so that the card plate 8 swings downward, so that the notch of the card plate 8 is against the outside of the safety rope, and the safety rope is further controlled, which can effectively protect the safety of the maintenance personnel and prevent accidents.
