Embodiment

[0021] Such as figure 1 As shown, two sets of single-station wire tensioners are connected in mirror image. The structure of the single-station wire tensioner is that one end of the operating handle 1 is provided with a hook 9 as a retrieval mechanism, and the other end of the operating handle 1 is flexibly connected by a thread. On the gear chuck 2, the gear chuck 2 is connected to the wire pulley 3, the wire rope 4 is wound on the wire pulley 3, the wire rope 4 is connected to the wire clamp 7 through the pulley 5, and the wire clamp 7 is equipped with a hanging ring 8, which is connected to the hook 9 are matched; the two sides of the wire wheel of the two single-station wire tensioners are respectively connected with the connecting steel plate 10 through the screw rod 6, and the connecting steel plate 10 is connected with a fixed hook 13, and a tension force is set between the connecting steel plate 10 and the fixed hook 13 Table 11 and ?80mm protection wire rope 12.

Abstract

The invention relates to a double-switching type tension indication wire grip. According to the wire grip, two single-station wire grip bodies are in mirror connection. According to each single-station wire grip body, a retrieving mechanism is arranged at one end of an operation handle, the other end of the operation handle is movably connected to a gear chuck, the gear chuck is connected with a wire spool, a steel wire rope is wound around the wire spool and is connected with a wire clamp through a pulley, and a hanging ring is installed on the wire clamp. One side of the wire spool of one single-station wire grip body is connected with one side of the wire spool of the other single-station wire grip body through a lead screw and a connecting steel plate, a fixing hook is connected to the connecting steel plate, and a tension meter and a protection steel wire rope are arranged between the connecting steel plate and the fixing hook. According to the wire grip, each single-station wire grip body can achieve wire gripping independently through the corresponding operation handle, the two single-station wire grip bodies can achieve double switching together, the structure is simple, cost is reduced, practicality is high, manufacturing is convenient, a large amount of labor is saved, and wire gripping can be achieved by a single person.

Description

technical field [0001] The invention relates to a construction and installation device for electric power equipment, in particular to a double-inverted tension indicating wire tensioner, which is suitable for wire tightening of power distribution lines and adjustment of wires within a gear distance, and belongs to the field of power distribution applications. Background technique [0002] At present, in the power distribution operation, the slack of the conductor is adjusted under conditions such as too long a tensile section or a too large cross-section of the conductor. Because the conductor cannot reach the specified sag after one operation, it is necessary to perform multiple operations to achieve the desired purpose, and the conductor The tuning operation requires the cooperation of multiple people, increasing the workload and personnel allocation; when working in special locations such as crossing highways, railways, bridges and important crossing lines, there are certa...
