Description

Technical Field

[0001] The utility model belongs to the field of tower climbing tools for electric power construction, and in particular relates to a climbing protector for an electric power pole tower. Background Art

[0002] The "Electricity Safety Work Regulations" issued by the State Grid Corporation of China stipulates in the power line part (trial): "Any work carried out at a location 2m or more from the ground (fall height reference plane) should be regarded as high-altitude work; and when working at high altitude on poles and towers, a double safety belt with a backup rope should be used. The safety belt and the safety rope should be hung on firm components at different parts of the poles and towers respectively, and the safety belt should be prevented from falling off the top of the pole or being damaged by sharp objects. When personnel are changing positions, the components they hold on to must be firm and they must not lose the protection of the backup rope."

[0003] For most power poles and towers, when constructing on the poles and towers, the construction workers will tie a safety rope around their waists and hang the safety buckle on the outer end of the safety rope on the structural angle steel of the poles and towers. When the workers step on air or slip, the safety rope will prevent the human body from falling. However, for some cylindrical cement poles and towers, there is no solid structural angle steel on the top. Only a support rod for supporting the electric wires is set on the top of the cement poles and towers, and the strength of the support rod is not enough to support the impact force generated when a person falls. Moreover, the support rod is located at the top of the cement poles and towers, which is not convenient for bolting the safety rope. Therefore, a power pole and tower climbing protector is proposed.

[0026] 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 of 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.

[0027] like Figure 1 As shown, a power pole tower climbing protector comprises a support pole 1, one side of the support pole 1 is provided with two clamping assemblies 5 distributed up and down, the clamping assemblies 5 can be clamped and fixed with the cement pole tower to achieve the fixation of the support pole 1; the support pole 1 is hollow, and a lifting rod 2 capable of lifting and lowering is provided inside the support pole 1, a speed difference automatic controller 4 is fixed on the upper end of the lifting rod 2, a connecting ring is provided on the rope at the lower end of the speed difference controller 4, and the safety rope tied by the construction personnel is bolted and fixed to the connecting ring;

[0028] It is worth mentioning that the speed difference controller 4 is also called a fall arrester, which can quickly brake and lock a falling object within a limited distance. It uses the speed difference of the falling object for self-control, and its safety rope is always in a tense state, allowing the staff to work easily and without any worries. Once a person slips and falls, the safety rope drives the rope in the speed difference controller 4 to be pulled out faster, and the control system in the speed difference controller 4 is automatically locked, so that the safety rope does not fall more than 0.2 meters, which can effectively ensure the personal safety of personnel.

[0029] In this embodiment, the lifting rod 2 is located in the inner cavity of the support rod 1 and slides with the support rod 1 in the vertical direction. Figure 2 As shown, one side of the support rod 1 is provided with two first fixing plates 12 distributed up and down, and a first screw rod 3 is rotatably connected between the two first fixing plates 12. A connecting block 21 is provided on one side of the lifting rod 2. The first screw rod 3 passes through the connecting block 21 along the vertical direction and is threadedly connected to the connecting block 21. By controlling the rotation of the first screw rod 3, the lifting and lowering movement of the lifting rod 2 can be controlled to adjust the height position of the speed difference automatic controller 4 to match the construction height of the construction personnel.

[0030] In order to ensure that the lifting rod 2 and the speed difference automatic controller 4 remain stable after height adjustment and prevent the lifting rod 2 from falling out of control and affecting the anti-fall protection function of the protector, the first screw rod 3 needs to have self-locking properties, that is, the thread lead angle of the first screw rod 3 is smaller than the equivalent friction angle.

[0031] Of course, the method of driving the lifting rod 2 to rise and fall includes but is not limited to the first screw rod 3 and other structures in the present embodiment. In some embodiments, the lifting rod 2 can also be directly driven to rise and fall by setting a telescopic rod, a hydraulic cylinder and other linear driving components on one side of the support rod 1. However, the telescopic rod and other linear driving components do not have the self-locking property of the first screw rod 3. Once the power source is lost, the lifting rod 2 will fall out of control, causing the protector to lose its anti-fall protection function.

[0032] In addition, in this embodiment, a clearance groove 11 is opened on one side of the support rod 1, and the clearance groove 11 is connected to the inner cavity of the support rod 1. The connecting block 21 on the lifting rod 2 reaches the outside of the support rod 1 through the clearance groove 11.

[0033] like Figure 3 and Figure 4 As shown, the clamping assembly 5 includes a mounting plate 51, a mounting block 511 is arranged on one side of the mounting plate 51, two mounting seats 13 are arranged on one side of the support rod 1 to correspond to the two clamping assemblies 5 respectively, the mounting block 511 is hinged with the mounting seat 13, and two clamping blocks 52 capable of synchronously sliding in the opposite direction are arranged on the side of the mounting plate 51 facing away from the mounting block 511, and the clamping block 52 is V-shaped, and the cement pole tower can be clamped and fixed by controlling the two clamping blocks 52 to approach synchronously, thereby achieving the fixation between the support rod 1 and the cement pole tower; compared with directly bolting the safety rope to the support rod at the top of the cement pole tower, the fixation of the clamping assembly 5 and the cement pole tower is convenient to operate and more firmly fixed;

[0034] In this embodiment, the two clamping blocks 52 are slidably connected to the mounting plate 51, and two second fixing plates 513 are provided on the mounting plate 51. A second screw rod 53 is rotatably connected between the two second fixing plates 513. Figure 5As shown, the second screw rod 53 is provided with a first external thread 531 and a second external thread 532 with opposite rotation directions and equal pitches. The first external thread 531 and the second external thread 532 respectively penetrate the two clamping blocks 52 and are threadedly connected to the clamping blocks 52. By rotating the second screw rod 53, the two clamping blocks 52 can slide synchronously in the opposite direction.

[0035] Furthermore, in order to ensure that the clamping block 52 stably clamps the cement tower, the second screw rod 53 needs to have self-locking properties, that is, the lead angles of the first external thread 531 and the second external thread 532 in the second screw rod 53 are both smaller than the equivalent friction angle.

[0036] Of course, the method of driving the two clamping blocks 52 to slide synchronously in opposite directions includes but is not limited to the second screw rod 53 in this embodiment. In some embodiments, two cylinders can be set on the mounting plate 51 to drive the two clamping blocks 52 separately and control the synchronous reverse sliding of the two.

[0037] In this embodiment, a rotating shaft 512 is fixed on the mounting block 511, and the rotating shaft 512 is rotatably connected to the mounting seat 13, thereby realizing the hinge connection between the mounting block 511 and the mounting seat 13; a torsion spring 54 is sleeved on the rotating shaft 512, and the two ends of the torsion spring 54 are respectively fixedly connected to the mounting block 511 and the mounting seat 13, and under the torsion force of the torsion spring 54, the mounting plate 51 has a tendency to flip downward, so as to realize the storage of the clamping assembly 5, reduce its occupied space, and facilitate the transfer and transportation of the protector.

[0038] It is worth mentioning that the number of the clamping components 5 includes but is not limited to two. In some embodiments, the number of the clamping components 5 can be greater than two and distributed in a vertical direction.

[0039] Working principle:

[0040] By setting a lifting rod 2 capable of lifting and lowering on the support rod 1, setting two clamping assemblies 5 distributed up and down on the lifting rod 2, and setting two clamping blocks 52 capable of synchronously sliding in opposite directions in the clamping assembly 5 to clamp the cement pole tower, the lifting rod 2 and the cement pole tower can be fixed to each other, and then the speed difference automatic controller 4 is set on the lifting rod 2 to connect with the safety rope on the construction personnel. Once the construction personnel fall, the safety rope drives the rope in the speed difference automatic controller 4 to be pulled out faster, and the control system in the speed difference automatic controller 4 is automatically locked, which can effectively ensure the personal safety of the personnel; and compared with directly bolting the safety rope to the support rod at the top of the cement pole tower, the fixing of the clamping assembly 5 and the cement pole tower is convenient to operate and more firmly fixed. By setting a torsion spring 54 on the rotating shaft 512, the mounting plate 51 has a downward flipping movement tendency, so as to realize the storage of the clamping assembly 5, reduce its occupied space, and facilitate the transfer and transportation of the protector.
