Description

Technical Field

[0001] The present invention belongs to the field of sling production, and in particular relates to a high-altitude sling for a power pole tower. Background Art

[0002] During the installation and transportation of electric poles, they need to be lifted by crane. Since the electric poles are cylindrical, it is difficult to fix them if they are transported horizontally. If they are transported vertically, the poles are too long and are prone to tilting during the lifting process, which causes the lifting equipment to swing in the air. At the same time, the poles are unstable and easily fall off during the shaking process.

[0003] Therefore, it is hoped that the existing high-altitude lifting equipment can be optimized and improved so as to be used to fix the vertically transported electric poles in place to prevent them from falling off. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0026] Combined with this Figures 1 to 6 An embodiment of a high-altitude lifting device for a power pole tower is described below. Specifically, the high-altitude lifting device for a power pole tower is constructed as a split structure, which has structures such as a limit plate 1, an arc-shaped clamping strip 103, and a rotating disk 102. By rotating the rotating shaft 107, the connecting rod 106 and the support rod 104 are driven to rotate. During the rotation process, the support rod 104 will drive the arc-shaped clamping strip 103 to rotate. Since the arc-shaped clamping strip 103 is arc-shaped, it will fit with the pole during the rotation process to prevent the pole from falling off during vertical transportation.

[0027] Please refer to Figures 1 to 6 , a high-altitude lifting device for a power tower, comprising:

[0028] A limiting disk 1 has a plurality of connecting blocks 101 in an annular array on the upper surface of the limiting disk 1, a turntable 102 is fixedly connected to the upper surface of the connecting blocks 101, a plurality of arc-shaped clamping strips 103 are arranged between the turntable 102 and the limiting disk 1, the arc-shaped clamping strips 103 are fixedly connected to a support rod 104 away from the open end, a plurality of slots 105 are arranged in an annular array on the turntable 102, the support rod 104 passes through the slots 105 and is fixedly connected to a connecting rod 106, the support rod 104 is in a right angle shape, wherein the vertical portion is fixedly connected to the connecting rod 106, the horizontal portion is fixedly connected to the arc-shaped clamping strips 103, the connecting rod 106 is fixedly connected to a rotating shaft 107, the rotating shaft 107 is threadedly connected to the upper surface of the turntable 102, a gear 108 is fixedly connected to the upper end of the rotating shaft 107, the rotating shaft 107 passes through the support disk 201 and is rotatably connected thereto. The arc-shaped clamping strip 103 is located between the rotating disk 102 and the limiting disk 1 and is fixedly connected to the supporting rod 104. The arc-shaped clamping strip 103 is rotated by the rotation of the supporting rod 104, and the vertically fixed pole is limited and fixed to prevent the pole from shaking and rotating from vertical to horizontal.

[0029] The rotating shaft 107 is rotatably connected to the upper surface of the turntable 102 and is fixedly connected to the connecting rod 106. During the rotation, the rotating shaft 107 rotates to drive the multiple connecting rods 106 to rotate, so that the support rods 104 and the arc-shaped clamping strips 103 at the corresponding positions rotate to complete the clamping and fixing.

[0030] When fixing the electric pole, the electric pole can be first inserted into the support plate 201 along the limit plate 1 and the turntable 102. When inserting, the hanger is first placed horizontally, and the mechanical arm is used to clamp the electric pole and insert it along the opening 3 on the limit plate 1. Then, a reduction motor whose output end is meshed with the gear 108 is used. The reduction motor rotates the transmission gear 108 and the rotating shaft 107 to rotate, and drives the connecting rod 106 and the support rod 104 to rotate. The support rod 104 will drive the arc-shaped clamping strip 103 to rotate during the rotation. Since the arc-shaped clamping strip 103 is arc-shaped, it will fit with the electric pole during the rotation. Since the rotating shaft 107 is threadedly connected to the turntable 102, after the rotation is completed, the rotating shaft 107 is in the final fixed state and cannot be rotated. During the fitting process, the electric pole cannot move, which can effectively prevent the electric pole from falling off due to the swing of the electric pole during high-altitude transportation.

[0031] The upper surface of the rotating disk 102 is fixedly connected with a protection rod 2, and the upper end of the protection rod 2 is fixedly connected with a support disk 201. The upper surface of the support disk 201 is provided with an opening 3, and the rotating disk 102 and the limiting disk 1 are both provided with corresponding openings 3 of equal diameter.

[0032] The protective rod 2 fixedly connected to the upper surface of the turntable 102 is used to connect the support plate 201 and the turntable 102 . The opening 3 provided on the upper surface of the support plate 201 can facilitate the electric pole to enter the support block 6 along the turntable 102 and the support plate 201 .

[0033] A through hole 4 is formed on the upper surface of the support plate 201 , and a fixing rod 401 is fixedly connected to the inner wall of the through hole 4 .

[0034] The through hole 4 provided on the upper surface of the support plate 201 is used to facilitate the engagement of the hook 5 with the support plate 201 . During the engagement, since the hook 5 is annular and has an opening, the opening position enters along the fixing rod 401 to realize the connection between the support plate 201 and the hook 5 .

[0035] A hook 5 is provided directly above the fixing rod 401 , and the hook 5 is fixedly connected to the supporting frame 502 via a chain 501 .

[0036] The hook 5 arranged directly above the fixing rod 401 is used to hook on the fixing rod 401, and the chain 501 is used to connect the support frame 502 and the hook 5. The support frame 502 can be fixed with the crane during lifting to lift the electric pole on the lifting device. The hook 5 arranged directly above the fixing rod 401 is used to connect the chain 501 and the support plate 201, and the chain 501 is used to extend the distance between the support plate 201 and the support frame 502 to accommodate the problem of the electric pole being too long during vertical transportation. After the fixation is completed, the hook 5 is engaged on the fixing rod 401, and the chain 501 and the hook 5 are fixed.

[0037] A support block 6 is fixedly connected to the lower surface of the limiting plate 1 , and a groove 601 is arranged on the upper surface of the support block 6 . The groove 601 is equidistant from the opening 3 .

[0038] The support block 6 fixedly connected to the lower surface of the limiting plate 1 is used to support the electric pole to prevent it from falling. At the same time, the groove 601 arranged on the upper surface of the support block 6 allows the electric pole to quickly enter the interior of the support block 6.

[0039] The arc-shaped clamping strip 103 is semicircular, and its radius is consistent with the opening 3 .

[0040] The arc-shaped clamping strip 103 is semicircular and can fit tightly to the pole to prevent the pole from shaking and falling off, and the radius setting consistent with the opening 3 can prevent the radius from being too large or too small to fit the pole.
