The counterweight 4 is passed through the fixed ring 7 through the support rod 1. After the counterweight 4 falls, the traction rope 8 is connected and fixed to the counterweight 4, and then the rope 3 is pulled back, so that the traction rope 8 is conveniently passed through the fixed ring 7. On the basis of the equipment maintenance rack, there is no need to continue to set up the rack for threading the traction rope 8.

[0026] See also Figure 1 , 2 The guide rope ring 2 includes a U-shaped member 22, and the U-shaped member 22 is fixedly connected to the support rod 1. In a preferred solution, when the support rod 1 is made of metal, the U-shaped member 22 is welded to the support rod 1.

[0027] Furthermore, the guide rope ring 2 also includes a first connecting ring 21, a U-shaped member 22 is fixedly connected to the first connecting ring 21, and the first connecting ring 21 is sleeved on the support rod 1. The above structure facilitates the fixed installation of the guide rope ring 2. The first connecting ring 21 can be fixedly installed on the support rod 1 with a tight fit, or a locking screw 23 can be screwed on the first connecting ring 21. After the first connecting ring 21 is sleeved on the support rod 1, the locking screw 23 is tightened to fix the guide rope ring 2 to the support rod 1.

[0028] See also Figure 1 , 3 The counterweight 4 is a cylinder, and the top of the counterweight 4 is an arc surface 41, so that the counterweight 4 can smoothly pass through the fixing ring 7 when pulling back the counterweight 4. A fixing hole 44 is provided on the top of the counterweight 4, and a first threaded hole 441 is provided on the counterweight 4 at the fixing hole 44. A set screw 45 is screwed into the first threaded hole 441. After the end of the rope 3 passes through the fixing hole 44, the rope 3 is fixed by the set screw 45.

[0029] Specifically, the connection structure for connecting the traction rope 8 is a notch 42 and a stop screw 43 provided at the bottom of the counterweight 4. The counterweight 4 is provided with a through hole 421 and a second threaded hole 422 on the side walls on both sides of the notch 42. The threaded end of the stop screw 43 passes through the through hole 421 and is screwed into the second threaded hole 422. Figure 7 A rope ring is provided at one end of the traction rope 8. After the rope ring is inserted into the slot 42, a limit screw 43 is installed to connect the traction rope 8 to the counterweight 4.

[0030] Of course, the counterweight 4 can also adopt a mountaineering hook, such as a hook disclosed in CN308326859S, in addition to the above structure. When the counterweight 4 adopts a mountaineering hook, the notch and the elastic buckle on the mountaineering hook are the connecting structure for connecting the traction rope 8.

[0031] Further, in order to facilitate and quickly retract the rope 3, see Figure 1 A rope collecting device 5 is installed on the end of the support rod 1 away from the rope guide ring 2, and the rope 3 is wound and installed on the rope collecting device 5. The rope 3 can be conveniently collected and released through the rope collecting device 5.

[0032] In a preferred embodiment, see Figure 4 The rope collecting device 5 includes a second connecting ring 51, a connecting plate 52 and a grooved wheel 54. The second connecting ring 51 is used for installation and connection with the support rod 1. The connecting plate 52 is fixedly connected to the second connecting ring 51. A fixed shaft 53 is installed on the connecting plate 52. The grooved wheel 54 is rotatably installed on the fixed shaft 53. A handle 55 is installed on the grooved wheel 54 on the side away from the connecting plate 52. The end of the rope 3 away from the counterweight 4 is wound around the grooved wheel 54. The grooved wheel 54 is rotated by the handle 55 to collect and release the rope 3. Figure 4 In the figure, one end of the fixed shaft 53 is a big head end, and the other end is provided with a screw rod. A mounting position for mounting the grooved wheel 54 is provided between the big head end and the screw rod. The diameter of the mounting position is smaller than the diameter of the big head end and larger than the diameter of the screw rod. In this way, the screw rod and the connecting plate 52 are positioned, and a nut is screwed on the screw rod to fix the fixed shaft 53 and the connecting plate 52.

[0033] During installation, screws are also screwed onto the second connecting ring 51 . After the second connecting ring 51 is put onto the support rod 1 , the screws are tightened to fix the rope collecting device 5 to the support rod 1 .

[0034] In addition to the manual structure mentioned above, the rope collecting device 5 can also adopt an electric structure. For example, a small motor of 6V, 12V or 24V or a motor reducer is installed on the side of the connecting plate 52 away from the grooved wheel 54. The grooved wheel 54 is installed on the output shaft of the small motor or the motor reducer. The rope 3 is collected and released by controlling the forward and reverse rotation of the motor.

[0035] In a preferred embodiment, in order to facilitate the storage of the high-altitude rope threading device of the present application, the support rod 1 can be telescopic. Specifically, the telescopic structure of the support rod 1 can be similar to the telescopic structure of a fishing rod or the telescopic structure of an umbrella center rod, or a structure that is threaded and connected in sequence.

[0036] Preferably, the rope 3 is a thin steel wire rope or a nylon rope with good flexibility.

[0037] The action process or principle of the utility model is as follows:

[0038] See also Figure 5 When in use, the support rod 1 is extended, the rope 3 is recovered through the rope collecting device 5, and the position of the counterweight 4 is adjusted so that the counterweight 4 is located at the end of the guide rope ring 2.

[0039] Lift the support rod 1, pass the counterweight 4 through the fixing ring 7, and then turn the rope collecting device 5 to release the rope 3. Figure 6 , the counterweight 4 falls onto the equipment rack.

[0040] See also Figure 7 A rope ring is provided at one end of the traction rope 8. After the rope ring is inserted into the notch 42, the limit screw 43 is installed to connect the traction rope 8 with the counterweight 4. The rope 3 is recovered by the rope collecting device 5, and the counterweight 4 and the traction rope 8 are passed through the fixing ring 7. After that, the support rods 1 are successively retracted and shortened, thereby completing the work of passing the traction rope 8 through the fixing ring 7.
