Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and in particular to a cable tensioner for power engineering cable installation. Background Technology

[0002] Electrical engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes projects that use electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation expansion projects. During the cable installation process in electrical engineering, cable tensioners are needed to tighten the cables. Cable tensioners, also called tightening devices, are used to tighten conductors during overhead line laying. Cable tensioners are divided into hand-operated hoists, ratchet cable tensioners, and double-hook cable tensioners.

[0003] Existing wire tensioners require operators to tighten bolts at both ends to secure the cable, a cumbersome and time-consuming process. According to existing technology, traditional wire tensioners require manual operation of a ratchet mechanism to tighten the conductor. This method suffers from low transmission efficiency and accuracy, and the sag cannot meet the precision requirements for measurement and calibration. Furthermore, due to a lack of specialized tools, workers often use iron bars or other tools, which can damage the conductor insulation, creating safety hazards. Moreover, tightening wires often requires two or more people, increasing labor costs and reducing efficiency. Therefore, existing wire tensioner operation methods are not only time-consuming and labor-intensive but also inefficient, urgently requiring improvement to enhance both efficiency and safety. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cable tensioner for power engineering cable installation, comprising a bearing component including a base plate and an upright plate integrally formed at the end of the base plate; and two clamping components that move in opposite directions outside the upright plate, each including a connecting plate, a connecting plate disposed within the connecting plate, and two support arms movably disposed outside the connecting plate, wherein one end of each of the two support arms is hinged to an angle plate, and one end of the angle plate is provided with a clamping plate.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0023] Example 1, referring to Figures 1 to 3 This is the first embodiment of the present invention, which provides a tensioner for cable installation in power engineering.

[0024] Specifically, the supporting component 100 includes a base plate 101 and an upright plate 102 integrally formed at the end of the base plate 101; and two clamping components 200 that move in opposite directions outside the upright plate 102, each including a connecting plate 201, a connecting plate 201a disposed within the connecting plate 201, and two support arms 203 movably disposed outside the connecting plate 201a, wherein one end of each support arm 203 is hinged to an angle plate 203a-1, and one end of the angle plate 203a-1 is provided with a clamping plate 204.

[0025] Each of the two support arms 203 is equipped with a clamping plate 204, and each of the two clamping assemblies 200 is equipped with two support arms 203. The clamping plates 204 are driven by the opposite movement of each pair of support arms 203, thereby completing the clamping of the cable.

[0026] It should be noted that the clamp 204 is made of rubber material, which ensures the friction between the clamp 204 and the cable. At the same time, the structural features of the clamp 204 can also prevent the cable from being damaged during the clamping process.

[0027] In summary, to complete the connection of two cables, it is only necessary to clamp each cable using the clamping components 200. After clamping the cable, the clamping components 200 are controlled to move relative to each other on the upright plate 102, thereby completing the connection of the two cables.

[0028] Example 2, refer to Figures 1 to 3 This is the second embodiment of the present invention.

[0029] Specifically, a bidirectional lead screw 104 and a slide rod 103a are rotatably mounted on the outside of the upright plate 102, and a storage basket 102a is bolted to the outer wall of the upright plate 102. The storage basket 102a facilitates the storage of materials needed for cable installation or removal by workers. The bidirectional lead screw 104 has threaded grooves on both sides of its outer wall with opposite directions of rotation (this is clearly described in existing technology and will not be elaborated upon here).

[0030] A reinforcing plate 101a is screwed to the outer wall of the base plate 101, and the outer wall of the reinforcing plate 101a is hinged to the vertical plate 102. The reinforcing plate 101a enhances the structural strength between the base plate 101 and the vertical plate 102, ensuring the stability of the tensioning operation.

[0031] The outer wall of the connecting plate 201 is provided with a transmission component 202, and the transmission component 202 includes a transmission block 202a. A transmission nut 202b is embedded in the outer wall of the transmission block 202a, and the inner wall of the transmission nut 202b is movably engaged with the bidirectional lead screw 104. Each clamping assembly 200 has a transmission component 202, and each transmission component 202 contains a transmission nut 202b. Both transmission nuts 202b can engage with the threads on both sides of the outer wall of the bidirectional lead screw 104 through their internal threads.

[0032] The outer wall of the transmission block 202a is also provided with a transmission through hole 202c, and the inner wall of the transmission through hole 202c is movably connected to the slide rod 103a. The movable engagement between the transmission through hole 202c and the slide rod 103a provides support for the clamping assembly 200 during movement, that is, the transmission assembly 200 can only be displaced within the stroke of the slide rod 103a.

[0033] It should be noted that the transmission component 202 also includes a second motor, the output end of which will be connected to the bidirectional lead screw 104.

[0034] In summary, when the two clamping components move relative to each other, the second motor is started, causing the bidirectional lead screw 104 to rotate. During the rotation, the bidirectional lead screw 104, through its threaded engagement with the transmission nut 202b, causes the two clamping components 200 to move closer to or further away from each other under the support of the slide rod 103a.

[0035] Example 3, referring to Figures 1 to 3 This is the third embodiment of the present invention.

[0036] Specifically, the angled plate 203a-1 has a support plate 203a hinged to its end away from the clamping plate 204, and a protrusion 201a-1 is hinged to one end of the support plate 203a. The protrusion 201a-1 is connected to the connecting plate 201a at its end away from the support plate 203a. A first drive shaft 203b and a second drive shaft 203c are respectively provided at the connection points between the two support arms 203 and the connecting plate 201a, and both the first drive shaft 203b and the second drive shaft 203c have drive gears arranged axially. In order to ensure the smooth operation of the cable clamping, the two support arms 203 on each clamping assembly 200 move as synchronously as possible.

[0037] The outer wall of the connecting plate 201a is provided with a first motor 205, and the output end of the first motor 205 is provided with an output gear, which meshes with the transmission gear. When the first motor 205 enters the working state, the transmission gear will cause the two support arms 203 to rotate synchronously through the cooperation of the output gear, thereby driving the two clamping plates 204 to clamp the cable.
