Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a limiting structure of a cable for a power transmission and transformation iron tower. Background Art

[0002] As we all know, the limiting structure of the cable for power transmission and transformation tower refers to the mechanism for limiting and protecting the cable in the power transmission and transformation tower. Its main function is to limit the movement range of the cable and prevent the cable from being displaced, worn or damaged due to wind, vibration or other external forces.

[0003] However, the clamping mechanism on the existing transmission and transformation tower cable limit structure is generally fixed on the equipment. When cables of different sizes need to be clamped and fixed, it is inconvenient to replace the clamping mechanism matching the cable, and new equipment can only be purchased, which increases the cost of use. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a limiting structure for cables used in power transmission and transformation towers.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a limiting structure for a cable used in a power transmission and transformation tower, comprising an installation box and a clamping mechanism, wherein the clamping mechanism is arranged in the installation box, and the clamping mechanism is provided with two, and the clamping mechanism comprises a through slot, a long block, a clamping plate, a slide slot, a slider, a first electric push rod, a limiting block, a limiting plate, a second electric push rod and a connecting plate, wherein the through slot is arranged on the installation box, one end of the long block passes through the through slot and is connected to the clamping plate, the slide slot is arranged on the long block, and one end of the slider is connected to the slider The groove is slidably connected, the other end of the slider is connected to one end of the first electric push rod, the other end of the first electric push rod is connected to one end of the limit block, the other end of the limit block abuts against the inner wall of the installation box, the limit plate is arranged at the bottom of the installation box, the top of the limit block contacts the bottom of the limit plate, one end of the second electric push rod is connected to the side of the installation box, the other end of the second electric push rod is connected to one end of the connecting plate, the connecting plate contacts the long block, and a through hole is opened on the installation box, and the through hole runs through the installation box.

[0008] A cover plate is provided at the bottom of the installation box, and the cover plate is connected to the installation box through a connecting mechanism. The connecting mechanism includes a connecting block and an electromagnet. One end of the connecting block is connected to the cover plate, and the other end of the connecting block is connected to the electromagnet. There are two connecting mechanisms.

[0009] In order to improve the stability, the present invention is improved in that the two connecting mechanisms are symmetrically arranged.

[0010] In order to improve the stability, the present invention is improved in that the two clamping mechanisms are symmetrically arranged.

[0011] In order to facilitate the operation of the equipment, the present invention is improved in that a controller is provided on the front side of the installation box, the controller is electrically connected to the first electric push rod, and the controller is electrically connected to the second electric push rod.

[0012] In order to facilitate carrying the cover plate, the present invention is improved in that a handle is provided on the top of the cover plate, and the handle is fixedly connected to the top of the cover plate.

[0013] In order to improve the sliding effect, the present invention is improved in that the sliding block matches the sliding groove.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a limiting structure for cables used in power transmission and transformation towers, which has the following beneficial effects:

[0016] The limiting structure of the cable for the power transmission and transformation tower has a clamping mechanism and an installation box in which the clamping mechanism is detachably arranged inside. When cables of different sizes need to be clamped and fixed and clamping mechanisms of different sizes need to be replaced, the clamping mechanism can be quickly removed and replaced with a clamping mechanism that matches the cable. This avoids the situation where, like traditional structures, it is inconvenient to replace clamping mechanisms of different sizes, resulting in the purchase of new equipment, thereby reducing the cost of use.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] When in use, first install the installation box 1 to the specified position of the transformer tower, and the installation method here is not specifically limited. Then, the cable to be positioned is passed through the through slot 3 and located between the two clamping plates 5. Then, the second electric push rod 11 is started to move the connecting plate 12, so that the long block 4 in contact with the connecting plate 12 will move in the through slot 3, driving the clamping plate 5 to move, so that the cable can be fixed. When the long block 4 moves, the slide 6 will move along the slider 7. When it is necessary to position cables of different sizes, it is necessary to replace clamps of different sizes. When the holding mechanism 2 is used, first start the first electric push rod 8 to shrink the first electric push rod 8, drive the limit block 9 to separate from the limit plate 10, and then lift the long block 4 upward to separate the long block 4 from the through slot 3, so that the clamping mechanism 2 can be separated from the installation box 1, and then replace it with a new clamping mechanism 2.

The connecting mechanism 15 is provided with two. After the cable is fixed, the cover plate 14 is merged with the installation box 1, and then the electromagnet 17 on the connecting block 16 is started, so that the electromagnet 17 adsorbs the installation box 1, and the cover plate 14 can be fixed on the top of the installation box 1. The opening at the top of the installation box 1 is sealed by the cover plate 14, which can prevent large particles from entering the interior of the installation box 1. The installation box 1 is made of iron, so that the electromagnet 17 can adsorb the installation box 1. .
