Description

Technical Field

[0001] The utility model relates to a guy wire, in particular to a tension rod device for an electric pole, belonging to the technical field of electrical engineering. Background Art

[0002] During the construction of power facilities, it is usually necessary to install guy wires at positions such as line corners, branches, strain, and terminal poles, with the aim of balancing the stress borne by the electric poles. The current guy wire system consists of materials such as guy wire clamps, extension rings, wedge-shaped wire clamps, UT wire clamps, steel strands, tension rods, pull plates, binding wires, insulators, ball head hanging rings, and bowl head hanging plates. Its manufacturing is difficult and the process is relatively complex. Moreover, the process quality of guy wire manufacturing is related to the safe and stable operation of the power grid and the personal safety of personnel. At present, the manufacturing process of distribution network power line guy wires is greatly affected by the professional level of personnel. Most construction workers only rely on traditional experience for construction, and the process quality varies. This results in long guy wire manufacturing time, damaged materials, the stability of the electric poles not meeting the standards, and being extremely prone to overturning accidents, seriously affecting the safe and reliable operation of the power grid. In addition, most existing guy wires are made on-site, and construction workers need to carry guy wires of corresponding lengths according to the height of the electric poles. Carrying steel guy wires in rolls like this not only greatly increases the labor burden of construction workers, but also makes on-site operations extremely inconvenient, and often requires the cooperation of various mechanical equipment to complete the manufacture of guy wires. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] In order to solve the problems existing in the existing guy wire manufacturing, such as complex process, large operation difficulty, inconvenient on-site construction, and difficult guy wire carrying, the utility model provides a tension rod device for an electric pole.

[0004] The technical solution of the utility model is as follows: A tension rod device for an electric pole includes a tension rod with a pull ring at one end and a wire clamp at the other end.

The quick connection mechanism includes a T-shaped block connected to the end of the wire clamp. Jack holes are respectively arranged at both ends of the horizontal block of the T-shaped block, and an axial strip-shaped jack hole is arranged on the vertical block of the T-shaped block. A locking sleeve and a locking nut are arranged at the port of the strip-shaped jack hole. Among them: the port of the strip-shaped jack hole is set as a conical shape with a larger outer diameter and a smaller inner diameter, the locking sleeve is set as a conical sleeve adapted to the port, and the locking nut is screwed to the periphery of the port.

[0005] The pull rod is set to at least three segmented rods, wherein: one end of the first segmented rod is connected to the pull ring, and the other end is provided with a first plug; one end of the second segmented rod is provided with a first slot matched with the first plug of the first segmented rod, and the other end is provided with a second plug; one end of the third segmented rod is provided with a second slot matched with the second plug of the second segmented rod, and the other end is connected to the wire clamp through a quick-connect mechanism, so as to facilitate construction workers to carry and assemble the pull rod on site. After the assembly is completed, one end of the pull rod is connected to the electric pole through the pull ring, and the other end of the pull rod is connected to the foundation through the wire clamp.

[0006] The first and second plugs are both disc-shaped and connected to the end of the segmented rod; the first and second slots are both arranged on the connecting block of the end of the segmented rod, the connecting block is arranged as a cylinder, the slot is arranged as a T-shaped groove adapted to the shape of the corresponding plug and the segmented rod, the radial side and axial end of the T-shaped groove are both arranged as open, and an elastic locking block is arranged in the T-shaped groove so that the plug and the segmented rod can be inserted through the radial side opening of the T-shaped groove. After insertion, the plug is located in the horizontal groove of the T-shaped groove, and the segmented rod extends outward from the axial end opening of the T-shaped groove, and the elastic locking block is used to prevent the plug from falling out of the slot.

[0007] The quick-connect mechanism includes a T-shaped block connected to the end of the wire clamp, and sockets are respectively provided at both ends of the horizontal block of the T-shaped block. An axial strip socket is provided on the vertical block of the T-shaped block, and a locking sleeve and a locking nut are provided at the port of the strip socket, wherein: the port of the strip socket is set to be a cone with a larger outside and a smaller inside, the locking sleeve is set to be a conical sleeve adapted to the port, and the locking nut is threadedly connected to the periphery of the port so that the rod head can be inserted into the strip socket 19, and the locking sleeve 18 can be inserted into the strip socket through the port, and then the locking nut is rotated to make the locking sleeve gradually penetrate into the strip socket, thereby realizing the locking of the pull rod and the T-shaped block, and then completing the quick connection of the pull rod and the wire clamp.

[0008] The wire clamp is configured as a U-shaped rod, the two rod heads of the U-shaped rod are respectively plugged into the sockets on the horizontal block of the T-shaped block, and the two rod head ends of the U-shaped rod are respectively screwed into the adjusting nuts, so that the position of the T-shaped block on the wire clamp can be adjusted by the adjusting nuts.

The flat head end of the screw extends outward from the T-shaped block, and the pointed end of the screw is screwed into the screw hole and connected to the end of the third segmented rod inserted into the strip socket without being connected, so that the rod head of the third segmented rod can be propped open by the pointed end of the screw, thereby further preventing the pull rod from detaching from the wire clamp, thereby ensuring the safety and stability of the pole.

[0010] The utility model has the following advantages and effects:

[0011] 1. Solve the problem of connecting the traditional UT clamp to the guy wire by means of back binding. The traditional installation method has high requirements for the professional skills of personnel, and strict requirements for the tightness and length of binding. It is only applicable to personnel with relatively high skill levels for installation, and the installation process is time-consuming and laborious, with a large physical consumption and high labor intensity for the operators. Making guy wires in a unified manner can greatly reduce the labor intensity of personnel, minimize the operation risks, improve work efficiency, and have significant social benefits.

[0012] 2. Shorten the construction time and save the project cost. According to the conventional installation method of guy wires, excluding the pre-burial of the guy wire plate, it takes about 30 minutes from the preparatory work before installation to the end of installation. However, when using the quick connection method for installation, the entire installation process only takes about 10 minutes. The operation process is stable and fast, the control method is simple and easy to learn, the operation time is flexible, and the work efficiency is high. Ordinary general workers can carry out the installation, which can save more than 70% of the installation cost, and the economic benefits are very obvious.

[0013] 3. Improve the power supply reliability and ensure the stable operation of the power grid. The use of this guy wire avoids the problem of strand damage and broken strands of the traditional guy wire caused by binding, which can greatly improve the power supply reliability and ensure the stable operation of the power grid.
