Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a combined wrench applicable to coaxial cables. Background Art

[0002] At present, in the process of electric power production, most of the communication methods used in the monitoring systems of hydropower stations include coaxial cables. However, due to the numerous wirings in the on-site control panels and cabinets, the positions for fixing the coaxial cables are mostly narrow, which makes it difficult to eliminate the defects of coaxial cable communication. Maintaining the normal communication of coaxial cables is an important operation related to the safe and stable operation of hydro-generator units and ensuring the security of the power system and the power dispatching data network. During the maintenance of the units, the maintenance personnel need to check each coaxial cable connector one by one. Those that are loose or unstable need to be tightened in time. There are dozens of coaxial cable heads in one unit, and it is time-consuming and laborious for the operators to tighten them. If there is a defect elimination work for coaxial cables, the requirement for time is even more stringent. At present, the commonly used wrench for tightening coaxial cables is only a wrench with a fixed length and caliber. Moreover, in order to prevent the coaxial cable body from being stressed, one hand needs to control the coaxial cable body, and the other hand uses the existing wrench to tighten or loosen the coaxial cable connector. The space near the cable trough box is narrow, which is not conducive to the operators working in the cabinet. The labor intensity of the operators is high, the efficiency is low, and it is time-consuming and laborious. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a combined wrench applicable to coaxial cables.

[0004] The purpose of the utility model is realized through the following technical solutions: A combined wrench applicable to coaxial cables, comprising:

[0005] A fixed jaw head, on which a fixed jaw is provided;

[0006] A movable jaw head, on which a movable jaw is provided;

[0007] A wrench body, which includes a fixed jaw section and a movable jaw section, and the tail of the fixed jaw section is detachably connected to the tail of the movable jaw section;

[0008] The fixed jaw head is hinged to the end of the fixed jaw section, and the movable jaw head is hinged to the end of the movable jaw section.

[0009] In this utility model, both the movable jaw head and the fixed jaw head are hinged to the wrench body, enabling the movable jaw head and the fixed jaw head to form a certain angle with the wrench body, facilitating the entry of the movable jaw head and the fixed jaw head into narrow spaces inside the switch cabinet for easy use. Meanwhile, by setting the wrench body in a split form as a fixed jaw section and a movable jaw section, the movable jaw head and the fixed jaw head can be used separately. The movable jaw head is used for tightening cable joints, and the fixed jaw head is used for stabilizing the cable, avoiding the need for the operator to manually stabilize the cable and improving the tightening efficiency.

[0010] In some embodiments, both the movable jaw head and the fixed jaw head are respectively hinged to the movable jaw section and the fixed jaw section through hinge shafts. Through the hinge shafts, the movable jaw head is hinged to the movable jaw section, and the fixed jaw head is hinged to the fixed jaw section.

[0011] In some embodiments, the hinge shafts are connected to the fixed jaw head, the movable jaw head, the fixed jaw section, and the movable jaw section by interference fits. By connecting the hinge shafts to the fixed jaw head, the movable jaw head, the fixed jaw section, and the movable jaw section by interference fits, the fixed jaw head and the movable jaw head can maintain a certain angle after bending, preventing the angles of the fixed jaw head and the movable jaw head from changing when encountering obstacles with a relatively light force when the wrench is inserted into a narrow space, thereby avoiding frequent adjustment of the angles of the fixed jaw head and the movable jaw head and facilitating use.

[0012] In some embodiments, a connection hole is provided at one end of the fixed jaw section connected to the movable jaw section, and a connecting rod is provided at one end of the movable jaw section connected to the fixed jaw section. The fixed jaw section and the movable jaw section are detachably inserted through the connecting rod and the connection hole. By inserting and connecting through the connection hole and the connecting rod, the connection structure is simple and easy to use.

[0013] In some embodiments, a magnetic attraction component is provided at the bottom of the connection hole. When the connecting rod is inserted into the connection hole, the magnetic attraction component at the bottom of the connection hole adsorbs the connecting rod to prevent the connecting rod from naturally disengaging from the connection hole.

[0014] In some embodiments, the magnetic attraction component includes a magnet. The magnet is used to adsorb the connecting rod.

[0015] In some embodiments, knurling is provided on both the movable jaw section and the fixed jaw section. The knurling increases the friction of the wrench body, plays an anti-slip role, and makes use more convenient.

[0016] This utility model has the following advantages:

[0017] 1. In the present utility model, the fixed pliers head is hinged to the fixed pliers jaw section, and the movable pliers head and the movable pliers jaw section are hinged, so that both the fixed pliers head and the movable pliers head can form a certain angle with the wrench body, facilitating the wrench to extend into the narrow space inside the switch cabinet and being convenient for use.

[0018] 2. By setting the wrench body in a split form as a fixed pliers jaw section and a movable pliers jaw section that are detachably connected, the fixed pliers head and the movable pliers head can be used separately. When fastening the cable connector, the movable pliers head is used to fasten the cable connector, and the fixed pliers head is used to hold the cable, improving the operation efficiency.
