Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wrenches, in particular to a wrench for disassembling and assembling a four-split conductor spacer. Background Art
[0002] During the construction process of power engineering, the newly built four-split high-voltage transmission line is a key part, and this design aims to improve the transmission efficiency and stability of electric energy. To ensure the normal operation of the transmission line, the installation and support of the conductors are particularly important. For this reason, each sub-conductor in each phase of the conductor needs to be precisely supported by installing a conductor spacer to ensure that the line spacing between them is maintained within a predetermined standard range. The purpose of this is not only to ensure the stability of the geometric structure of the line and prevent the conductors from coming into contact with each other due to reasons such as wind vibration or self-weight, but more importantly, to avoid the whip phenomenon between the sub-conductors. This refers to when the conductors vibrate due to reasons such as wind, adjacent sub-conductors may collide with each other, resulting in serious wear or even breakage, affecting the reliability and safety of the line.
[0003] However, in actual construction, especially during the process of installing the four-split conductor spacer along the line, the staff often faces many challenges. Traditionally, this operation needs to be completed with a relatively primitive disassembly and assembly wrench, which undoubtedly increases the difficulty and complexity of the construction. Using the primitive disassembly and assembly wrench not only takes time and effort, but also poses a greater risk to the safety of construction workers in the high-altitude working environment, and there is also a risk of the wrench falling when removing it. Since the installation position of the spacer is usually high, the construction workers need to operate in a narrow and unstable space for a long time, which not only places higher demands on their physical strength, but also greatly increases the possibility of construction errors. Therefore, finding a more efficient and safe spacer disassembly and assembly wrench has become a technical problem to be solved urgently. Some power companies and research institutions have begun to explore the use of new tools and technologies to optimize this process, such as developing special tools suitable for the installation of four-split conductor spacers, or adopting advanced technologies such as remote control and automation to reduce the risks and difficulties of manual operations. These efforts aim to improve construction efficiency, reduce labor costs, and ensure construction quality and safety. Content of the Utility Model

One end of the direction-adjusting baffle 3 is fixedly provided with a bolt 33. One end of the pressing head 2 is provided with a bolt hole 21. The bolt 33 and the bolt hole 21 are used in cooperation to adjust the distance between the direction-adjusting baffle 3 and the pressing head 2.
[0024] Preferably, the direction-adjusting baffle 3 of this embodiment includes clamping plates 31 on both sides and a baffle 32 in the middle. The middle of the baffle 32 is hinged to the clamping plates 31 so that the baffle can be horizontally blocked after passing through the installation hole.
[0025] Preferably, the adjustable ratchet 11 includes a forward pawl and a reverse pawl. Springs are arranged between the forward pawl and the reverse pawl and the side wall to push the pawls to catch the ratchet. A stop block is arranged between the forward pawl and the reverse pawl, and a rotating handle 12 is arranged to drive the stop block to switch between the forward pawl and the reverse pawl. When the stop block is driven by the rotating handle 12 to tilt to one side, it will push open the corresponding pawl on that side and make the pawl on the other side catch the ratchet 11 in one direction, realizing the switching of the rotation direction of the ratchet 11.
[0026] Preferably, in this embodiment, grip grooves 13 for improving the grip feel are arranged on the side surface of the handle 1. The grip grooves 13 can be set arbitrarily according to use. In this embodiment, four grip grooves 13 are set, which are adapted to the spacing of human fingers.
[0027] Preferably, an anti-drop belt 14 is arranged at the lower end of the handle 1 of this embodiment. The anti-drop belt 14 is provided with a magic tape to tightly wrap the arm. During installation and removal, the anti-drop belt 14 can be wound around the arm and the magic tape can be buckled to prevent the wrench from falling due to accidents. In addition, this embodiment also sets a plurality of binding sites on the magic tape of the anti-drop belt 14, which can adapt to the actual use situation of the operator.
[0028] Preferably, a connecting bolt 15 is detachably connected between the upper part and the lower part of the handle 1. The upper half part is the part where the ratchet wheel is arranged, which can be understood as the head of the handle, and the lower half part is the gripping part of the handle. Through this setting, the operator can select a suitable gripping part according to his own use feeling, so as to significantly improve his own use experience.
