Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire tighteners, in particular to a wire tightener for cable installation. Background Art
[0002] High-voltage lines are the main power transmission lines of the power system and are usually erected at high altitudes. The tightness of high-voltage lines is related to the normal transmission of the entire power line. If the power line is too loose, there will be series interference between adjacent transmission lines, affecting the normal operation of the power system. The daily maintenance work of the power system includes line detection, line replacement, and line tightening. Due to the large tension of the wire, the wire will become loose after being erected for a long time. Usually, a hand-operated wire tightener is used to tighten the wire, and an electrician needs to work at high altitudes. The wire to be tightened is in a loose state, and the tightening stroke of the hand-operated wire tightener is limited each time. To save physical strength, the wrench of the hand-operated wire tightener is relatively long, resulting in a large range of movement of the wrench. However, due to the difficulty of working at high altitudes and the unstable standing posture of the electrician, it is difficult to find a suitable force application point, and each tightening operation brings great difficulties to the electrician. Content of the Utility Model
[0003] The utility model provides a wire tightener for cable installation to solve the above technical problems.
[0004] The technical solution of the utility model is realized as follows: A wire tightener for cable installation includes a fixed frame. Fixed rods are respectively inserted through the front and rear ends of the fixed frame. A fixed hook is inserted through the fixed rod at the front end of the fixed frame. A horizontal through hole is provided in the middle position of the fixed frame. A rotating rod is inserted through the through hole. One end of the rotating rod passes through the fixed frame and is provided with a ratchet wheel. The other end of the rotating rod passes through the fixed frame and is connected with a plug. A convex block is provided at the central position of the outer side of the ratchet wheel. A movable wrench is movably sleeved on the convex block. An adjusting bolt is inserted through the wrench head of the movable wrench, and the adjusting bolt is fixed on the convex block. The movable wrench can move back and forth along the adjusting bolt by relying on the wrench head. An articulated rod and a stop rod are arranged outside the fixed frame on one side in a vertically distributed manner. A torsion spring and a ratchet pawl are sleeved on the articulated rod. The ratchet pawl is engaged with the ratchet wheel. One end of the torsion spring abuts against the top of the fixed frame, and the other end of the torsion spring abuts against the ratchet pawl. An auxiliary rod is inserted through the lower part of the fixed rod at the rear end of the fixed frame. A traction rope is connected to the auxiliary rod. The other end of the traction rope is fixed on the rotating rod. A pulley is also sleeved on the traction rope, and a movable hook is connected to the pulley.
[0005] Furthermore, a fixed wrench is installed on the side of the fixed frame facing away from the movable wrench.
[0006] Furthermore, the protrusion is a hexagonal nut structure, and the front half of the adjusting bolt is matched and connected to the protrusion; the wrench head has a hexagonal recess along the inner side facing inward, and the wrench head has a movable hole along the outer side facing inward, and the adjusting bolt passes through the movable hole.
[0007] Furthermore, the top end of the pawl extends above the fixed frame, and the pawl is provided with a convex corner upward along the bottom end.
[0008] By adopting the above technical solution, the beneficial effects of the utility model are:
[0009] The utility model discloses a tensioner for cable installation, which includes a fixed frame, and a fixed hook is inserted into the fixed rod at the front end of the fixed frame. A rotating rod is inserted into the through hole in the middle of the fixed frame, and one end of the rotating rod is provided with a ratchet after passing through the fixed frame, and the other end is connected to a plug after passing through the fixed frame. An adjustable wrench is movably sleeved on the protrusion on the outer side of the ratchet, and an adjusting bolt is inserted into the wrench head of the adjustable wrench, and the adjusting bolt is fixed to the protrusion. The fixed frame is provided with an articulated rod and a stopper rod distributed up and down along one side facing outward, and a torsion spring and a pawl are sleeved on the articulated rod, and the pawl is engaged with the ratchet. A traction rope is connected to the auxiliary rod at the rear end of the fixed frame, and the other end of the traction rope is fixed to the rotating rod. A pulley is also sleeved on the traction rope, and a movable hook is connected to the pulley. Hold the adjustable wrench so that the wrench head is placed on the protrusion, and turn the adjustable wrench to drive the ratchet and the rotating rod to rotate. After completing a tightening stroke, the adjustable wrench can be moved outward to disengage the wrench head from the protrusion. After the adjustable wrench is reset, it is placed on the protrusion again. The tightening can be completed in sequence. Although the tightening stroke is limited each time, the electrician does not need to adjust his standing posture, which can save the electrician's physical strength and greatly reduce the difficulty of tightening the wire.

[0015] As Figure 1-2 described, the wire tightening device for cable installation includes a fixed frame 1. Fixed rods 2 are respectively inserted through the front and rear ends of the fixed frame 1. A fixed hook 3 is inserted through the fixed rod 2 at the front end of the fixed frame 1. A horizontally arranged through hole 4 is formed in the middle position of the fixed frame 1. A rotating rod 5 is inserted through the through hole 4. One end of the rotating rod 5 passes through the fixed frame 1 and is provided with a ratchet wheel 6. The other end of the rotating rod 5 passes through the fixed frame 1 and is connected with a plug 7. A convex block 8 is provided at the central position on the outer side of the ratchet wheel 6. A movable wrench 9 is movably sleeved on the convex block 8. An adjusting bolt 11 is inserted through the wrench head 10 of the movable wrench 9. The adjusting bolt 11 is fixed on the convex block 8. The movable wrench 9 can move back and forth along the adjusting bolt 11 by relying on the wrench head 10. The fixed frame 1 is provided with a hinged rod 12 and a stop bar 13 which are distributed up and down on one side facing outward. A torsion spring 14 and a pawl 15 are sleeved on the hinged rod 12. The pawl 15 meshes with the ratchet wheel 6. One end of the torsion spring 14 abuts against the top of the fixed frame 1, and the other end of the torsion spring 14 abuts against the pawl 15. An auxiliary rod 16 is inserted through the lower part of the fixed rod 2 at the rear end of the fixed frame 1. A traction rope 17 is connected to the auxiliary rod 16. The other end of the traction rope 17 is fixed on the rotating rod 5. A pulley 18 is also sleeved on the traction rope 17. A movable hook 19 is connected to the pulley 18.
[0016] The fixed frame 1 of this embodiment is installed with a fixed wrench 20 on the side facing away from the movable wrench 9. When the wire is too loose, hold the fixed wrench 20 with one hand and hold the movable wrench 9 to rotate for tightening the wire, and the wire tightening operation can be quickly completed.
