DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 and Figure 2A power iron tower with an anti-falling function may include a tower body 10, a plurality of connectors 20, at least one auxiliary protection pipe 30, a plurality of anti-falling parts 40, and a top guardrail 50. The top guardrail 50 is surrounded by a closed outer ring structure, and the top guardrail 50 is welded and fixed to the top of the tower body 10, so that construction workers can use the top guardrail 50 to shield and prevent falling after climbing to the top of the tower body 10. The plurality of connectors 20 can be detachably mounted and fixed on the outer edge of the connector 20 by means of locking members such as bolts, and the plurality of connectors 20 after being mounted and fixed are arranged at intervals in the height direction of the outer ring of the tower body 10, so as to support the auxiliary protection pipe 30. At least one auxiliary protection pipe 30 is supported and fixed on the outer side of the tower body 10 by means of the connector 20 and locking members such as bolts, and a movable groove 31 penetrating one side of the auxiliary protection pipe 30 is formed on the outer wall of the auxiliary protection pipe 30, and the movable groove 31 is used to cooperate with the anti-falling part 40. At least one anti-falling component 40 is movably provided in the inner cavity of each auxiliary protection tube 30. The anti-falling component 40 can be fastened to the safety belt of the maintenance personnel, and when the construction personnel fall, the friction resistance between the anti-falling component 40 and the inner wall of the auxiliary protection tube 30 can be used to prevent the construction personnel from falling.

[0025] See also Figures 3 to 5 The anti-falling member 40 may include a sliding seat 41, a rotating shaft 42, an adjusting frame 43, two pushing frames 44, two anti-falling frames 45, a sling 46, a hanging ring 47, a torsion spring 48 and two positioning shafts 49. The sliding seat 41 is movably arranged in the inner cavity of the auxiliary protection tube 30, and the outer diameter of the sliding seat 41 is smaller than the inner diameter of the auxiliary protection tube 30, so that no friction is generated between the two. The rotating shaft 42 is passed through the middle of the sliding seat 41 and is rotatably connected to the sliding seat 41, and the adjusting frame 43 is sleeved in the middle of the rotating shaft 42 and fixedly connected thereto, so that the adjusting frame 43 can be deflectedly arranged in the sliding seat 41 by the rotating shaft 42. The two ends of the adjustment frame 43 are rotatably connected to the two push frames 44 respectively, and the ends of the two push frames 44 away from the adjustment frame 43 are rotatably connected to the middle of the two anti-fall frames 45 respectively. The two anti-fall frames 45 are rotatably connected to the inner bottom of the sliding seat 41 in opposite directions, so that when the adjustment frame 43 deflects, the two push frames 44 can be used to push the two anti-fall frames 45 respectively. Figure 4 and Figure 5As shown, one end of the anti-fall frame 45 can be rotatably connected to the bottom of the sliding seat 41 by using a positioning shaft 49 that passes through the anti-fall frame 45 and is fixedly connected thereto. The anti-fall frame 45 is set to an arc shape with an outer diameter that matches the inner diameter of the auxiliary protection tube 30, so that the anti-fall frame 45 can deflect and move through the sliding seat 41 and fit and contact with the inner wall of the auxiliary protection tube 30. The torsion spring 48 is sleeved on the outer wall of the rotating shaft 42, and the two ends of the torsion spring 48 are respectively fixedly connected between the sliding seat 41 and the rotating shaft 42. The deformation and force storage direction of the torsion spring 48 is the same as the deflection direction of the rotating shaft 42 when the rotating shaft 42 is deflected by the adjustment frame 43 and the pushing frame 44 to push the anti-fall frame 45 outward, so that when the construction personnel climb, the torsion spring 48 can be used to prevent the anti-fall frame 45 from deflecting outward and generating friction with the auxiliary protection tube 30. One end of the sling 46 is fixedly connected to the rotating shaft 42, and the other end of the sling 46 passes through the movable groove 31 and extends out of the auxiliary protection tube 30. The sling 46 is wound on the outer wall of the rotating shaft 42, and the winding direction of the sling 46 is opposite to the deflection direction of the rotating shaft 42 when the adjusting frame 43 and the pushing frame 44 push the anti-fall frame 45 outward when the rotating shaft 42 deflects, so that the sling 46 can pull the rotating shaft 42 to deflect after being released to the end on the rotating shaft 42, and the anti-fall frame 45 is driven to press against the inner wall of the auxiliary protection tube 30. One end of the sling 46 extending out of the auxiliary protection tube 30 is fixedly connected to a lifting ring 47 that can be connected to a safety belt. When the construction workers climb the tower body 10, they can pass the connection part of their safety belt through the lifting ring 47 and tie it up or hook it to stabilize it. When the construction workers fall, they can first pull the sling 46 to release it, and after the sling 46 is released and is not wrapped around the rotating shaft 42, it can drive the adjustment frame 43 to deflect, and when the adjustment frame 43 deflects, it can drive the push frame 44 to move, and use the push frame 44 to push the anti-fall frame 45 connected to it outward to deflect. The outer wall of the anti-fall frame 45 and the inner wall of the auxiliary protection tube 30 can be covered with a protective coating to increase the friction resistance between the two, so that the anti-fall frame 45 can better bear the force and prevent the maintenance personnel from falling.

[0026] In this embodiment, two groups of auxiliary protection tubes 30 can be symmetrically arranged on each side of the tower body 10, and each group of auxiliary protection tubes 30 is provided with a group of anti-falling parts 40. Before climbing the tower body 10, the construction personnel can first use the anti-falling parts 40 in the auxiliary protection tubes 30 on the same side to connect the safety belts on the left and right sides respectively, so that when the maintenance personnel fall accidentally, the anti-falling parts 40 on both sides can evenly bear the force and stably support the maintenance personnel.

[0027] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
