Description
Technical Field
[0001] The utility model relates to the technical field of line tightening devices, and more particularly to a line tightening device for electric power installation. Background Art
[0002] At present, when installing overhead lines, power workers lay out the lines in accordance with the design specifications and standards. After the construction of new power lines is completed, the conductors must be tightened on the poles and towers. When tightening the lines, a tightening device is required.
[0003] Existing tensioning devices are typically used on the top of utility poles. Therefore, they need to be fixed in place before use, typically by clamping them to the outside of the pole. However, these clamping devices are bulky, making them difficult to operate at high altitudes. Furthermore, fine-tuning the angle after securing the clamping position is difficult, causing the wire winding direction to tilt during tensioning, affecting tensioning accuracy. Given this, we propose a tensioning device for power installations. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a tightening device for power installation to solve the technical problems that the current tightening device with a clamping structure has a large overall volume, increases the difficulty of operation when fixed in a high-altitude installation position, and is difficult to fine-tune the angle after the clamping position is fixed, resulting in the wire winding direction being tilted during the tightening process, affecting the accuracy of the tightening.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a wire tensioning device for electric power installation, comprising a winding assembly, a connecting base fixedly mounted on the bottom of the winding assembly, and a clamping member detachably mounted on the side end of the connecting base;
[0006] The connecting base includes a U-shaped plate, a T-shaped slot is provided on the side end of the U-shaped plate where it is combined with the clamping member, and a limiting slot is provided on the bottom side of the U-shaped plate at the bottom and is connected to the T-shaped slot;
[0007] The clamping member includes two arc-shaped clamping plates, and the side ends of the two arc-shaped clamping plates are fixed with extension plates. A connecting member is rotatably connected between the two extension plates on one side, and the two extension plates are provided with slots that are rotatably adapted to the connecting member. A T-shaped block combined with the T-shaped slot is fixed on the side wall of the arc-shaped clamping plate close to the side of the connecting base. A limiting plate combined with the limiting slot is fixed on the bottom of the T-shaped block, and a limiting member that can fit with the top of the U-shaped plate is fixed on the top of the T-shaped block.
[0008] The utility model realizes a detachable connection between the winding assembly and the clamping part through the design of the connecting base. In this way, the installation position of the clamping part can be fixed before the high-altitude tightening operation, and then the winding assembly and the clamping part can be assembled by combining the T-slot, the limit slot, the T-block and the limit plate. The installation position of the connecting base can be limited by the setting of the limit part. Such structural coordination can reduce the overall weight through sub-packaging and reduce the difficulty of high-altitude fixed position operation. At the same time, the tightening direction can be adjusted when the clamping part is fixed in position, which solves the problem of difficulty in fine-tuning the tightening direction and improves the accuracy of the overall structure during high-altitude tightening operation.
[0009] Preferably, the limiting member includes a fixed column, and a ring array on the outer wall of the fixed column has several elastic external teeth, the external rotation of the fixed column is installed with a limiting kit that can fit with the top of the U-shaped plate, and the inner wall of the limiting kit has a ring array on the inner wall of the limiting kit. The inner teeth mesh with the external teeth.
[0010] Preferably, two connecting sleeves are fixedly provided on the front side of the extension plate on the other side, a U-shaped insertion rod is inserted between the two extension plates and the connecting sleeves, and a threaded rod is threadedly connected between the two connecting sleeves and the U-shaped insertion rod.
[0011] Preferably, the upper plate of the U-shaped plate is movably sleeved externally with a sliding block fixedly connected to the bottom of the winding assembly, and the bottom of the sliding block is in contact with the top of the lower U-shaped plate.
[0012] Preferably, a fixing plate is fixedly provided on the top of the upper side plate of the U-shaped plate, and an electric push rod fixedly connected to the winding assembly is fixedly provided on the side of the fixing plate close to the winding assembly.
[0013] Preferably, a rubber pad is fixedly provided on the arc surface of the two arc-shaped clamping plates on the opposite side, and a handle is fixedly provided on the middle part of the outer side surface of the arc-shaped clamping plate on the front side.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. The utility model realizes the tightening of the cable by the cooperation between the clamping member and the connecting base provided with the winding assembly, combined with the limiting effect provided by the limiting member. In the actual operation process, in order to reduce the influence of the volume and weight of the equipment during installation on the installation accuracy, the clamping member can be assembled first so that the clamping member and the cable are laid in the same direction, and then the T-shaped groove provided on the side end of the connecting base is plugged into the T-shaped block provided on the clamping member to fix the installation position of the winding assembly. The installation position of the connecting base can be limited by the rotation of the limiting member to achieve the effect of overall assembly. In this way, the cable can be tightened by combining the pull belt structure installed on the winding assembly with the cable;
[0016] By pre-conditioning the installation direction to keep it in the best tightening state with the cable, the split installation effectively reduces the difficulty of cable tightening operations in high-altitude working environments, facilitates the adjustment of the tightening direction, and improves the accuracy of high-altitude tightening operations.

The two connecting plates on one side of the opening can improve the locking effect of the opening through the cooperation of the connecting sleeve, U-shaped plug rod and threaded rod. This connection method is not easy to loosen during use, which improves the stability of the installation position. BRIEF DESCRIPTION OF THE DRAWINGS
