Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a cable tensioner for installing electric power engineering cables. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. At the same time, it can be understood as power transmission and transformation industry expansion engineering. During the cable installation process of power engineering, it is necessary to use a tensioner to tighten the cable. The tensioner, also called a tensioner, is used to tighten the wire during the construction of overhead line laying. The tensioner is divided into hand winch, ratchet tensioner and double hook tensioner.

[0003] During the use of the existing wire tensioner, the operator needs to tighten the bolts separately to fix the cables at both ends. This operation step is not only cumbersome, but also time-consuming and labor-intensive. According to prior art records, the traditional wire tensioner needs to manually turn the ratchet tightener to tighten the wire. This method has low transmission efficiency and low transmission accuracy, and the sag cannot meet the accuracy requirements of measurement and metering. In addition, due to the lack of special tools, staff often use iron rods or other tools for operation, which may not only cause damage to the insulation sheath of the wire and cause safety hazards, but also often requires two or more people to complete the work when tightening the wire, which undoubtedly increases labor costs and reduces work efficiency. Therefore, the existing operation method of the wire tensioner is not only time-consuming and labor-intensive, but also has low tightening efficiency, and urgently needs to be improved to improve work efficiency and safety. Summary of the invention

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

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

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

[0024] Specifically, the bearing assembly 100 includes a base plate 101 and a vertical plate 102 integrally formed at the end of the base plate 101; and two clamping assemblies 200 that move toward each other outside the vertical plate 102, including a connecting plate 201, a connecting plate 201a arranged in the connecting plate 201, and two support arms 203 movably arranged outside the connecting plate 201a, wherein one end of the two support arms 203 is hinged with an angular plate 203a-1, and one end of the angular plate 203a-1 is provided with a clamping plate 204.

[0025] Wherein, the two support arms 203 are each provided with a clamping plate 204, and the two clamping assemblies 200 are each provided with two support arms 203, and the clamping plates 204 are driven by the movement of each two groups of support arms 203 toward each other, thereby completing the clamping of the cable.

[0026] It should be noted that the clamping plate 204 is made of rubber material to ensure the friction between the clamping plate 204 and the cable. At the same time, the structural characteristics of the clamping plate 204 can also be used to prevent the cable from being broken when the clamping plate 204 is clamping the cable.

[0027] In summary, to complete the docking of two cables, it is only necessary to clamp each cable through each clamping assembly 200. After clamping the cable, each clamping assembly 200 controls the two clamping assemblies 200 to move relative to each other on the vertical plate 102, thereby completing the docking of the two cables.

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

[0029] Specifically, a bidirectional lead screw 104 and a slide bar 103a are respectively rotated on the outside of the vertical plate 102, and a storage basket 102a is installed on the outer wall of the vertical plate 102 by bolts. The storage basket 102a can be used by the staff to store the work required for installing or removing the cables. The outer wall of the bidirectional lead screw 104 is provided with thread grooves in opposite directions on both sides (the prior art has been clearly recorded and will not be repeated here).

[0030] The outer wall of the bottom plate 101 is screwed with a reinforcing plate 101a, and the outer wall of the reinforcing plate 101a is hinged to the vertical plate 102. The arrangement of the reinforcing plate 101a improves the structural strength of the bottom plate 101 and the vertical plate 102, ensuring the stability of the tightening work.

[0031] The outer wall of the connecting plate 201 is provided with a transmission member 202, and the transmission member 202 includes a transmission block 202a, and the outer wall of the transmission block 202a is embedded with a transmission nut 202b, and the inner wall of the transmission nut 202b is movably matched with the bidirectional lead screw 104. Each clamping assembly 200 has a transmission member 202, and each transmission member 202 is provided with a transmission nut 202b, and both transmission nuts 202b can be matched 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 bar 103a. The movably coordinated transmission through hole 202c and the slide bar 103a provide support for the clamping assembly 200 during movement, that is, the transmission assembly 200 can only move within the travel of the slide bar 103a.

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

[0034] In summary, when the two clamping components are to move relative to each other, the second motor is started to rotate the bidirectional screw 104. During the rotation process, the bidirectional screw 104 cooperates with the thread of the transmission nut 202b to make the two clamping components 200 move closer to or farther away from each other under the support of the slide rod 103a.

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

[0036] Specifically, the angular plate 203a-1 is hinged with a support plate 203a at one end away from the clamping plate 204, and a protrusion 201a-1 is hinged at one end of the support plate 203a. The protrusion 201a-1 is connected to the connecting plate 201a at one end away from the support plate 203a. The connection between the two support arms 203 and the connecting plate 201a is respectively provided with a first transmission shaft 203b and a second transmission shaft 203c, and the first transmission shaft 203b and the second transmission shaft 203c are both provided with transmission gears in the axial direction. In order to ensure the smooth clamping of the cable, the two support arms 203 on each clamping assembly 200 move synchronously as much as possible.

[0037] The outer wall of the connecting plate 201a is provided with a first motor 205, and an output gear is provided at the output end of the first motor 205, and the output gear is meshed with the transmission gear. When the first motor 205 enters the working state, the transmission gear will cooperate with the output gear to make the two support arms 203 rotate synchronously, so as to drive the two clamping plates 204 to clamp the cable.
