Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, 2, 3, the utility model comprises a support 5, a drag cable 9 and a seat plate 7 with a pull ring 8 at one end, the support shaft 3 of the large sprocket 1 is provided at the top of the support 5, and below the support shaft 3, A drive shaft 14 with a small sprocket 16 is arranged on the support 5, and the drag cable 9 is connected with the seat plate 7 through a tension transmission device. The tension transmission device includes a support shaft 3 with a large sprocket 1 arranged on the top of the support 5, the large sprocket 1 is arranged at the center of the support shaft 3, and the support shaft 3 is also fixed with a cable reel 2, the cable reel 2. Both ends are respectively connected with the drag cables 9; the tension transmission device also includes a drive shaft 14 with a small sprocket 16 arranged on the support 5, and the small sprocket 16 is set on the drive shaft 14 through a one-way overrunning clutch 12; The large sprocket 1 drives the small sprocket 16 to rotate through the chain 11; the drive shaft 14 is symmetrically provided with rope connecting rods 10, and the two rope connecting rods 10 are movably connected with the two ends of the seat plate 7 by ropes 18, and the rope connecting rods 10 is connected with rope 18 by connecting bolt 13. Both ends of the cable reel 2 are provided with a tension regulating device, referring to Fig. 4-a, Fig. 4-b, the tension regulating device comprises an adjustment spring 21, and one end of the adjustment spring 21 is connected to the reel 2 through a connecting plate 22, The other end is connected with the spring seat 23, and the spring seat 23 is installed on the support 5 through the adjusting bolt 24, and corresponding threaded holes are provided on the support 5; Schematic diagram of working at position 2 after the position of adjusting bolt 24 in the pulley tension adjusting device of the utility model changes.

Corresponding to the rope connecting rod 10 on the bracket 5 is also symmetrically provided with a pair of angle limiting devices, referring to Fig. The boss 19 and the limiter beam 17 are provided with a limit spring 20 matched with the boss 19 . The angle between the limiter crossbeam and the vertical direction is 55°, so that the maximum swing angle of the rope connecting rod 10 is 55° to ensure safety. The support 5 is also provided with a block pulley support plate 6, and the block pulley support plate 6 is provided with a pulley block 25 for limiting the dragline 9, and one end of the dragline 9 passes through the block pulley 25 and is fixed on the dragline reel 2.
