Description

Technical Field

[0002] A wire tightener usually uses a ratchet and a lever structure to tighten two groups of cables, having high efficiency and labor-saving effect.

[0003] In the existing electric power construction process, a wire winding wheel is usually used for pulling wires. However, due to the fact that some cables are long and cannot be cut, and the wire wheel is small, it is impossible to pull after excessive winding, which is not conducive to electric power construction. At the same time, since the wire tightener is stressed unidirectionally during operation, the wire tightener is extremely likely to rotate automatically, which is not conducive to the safety protection of electric power operation during the college entrance examination.

[0017] The beneficial effects of the present invention are as follows: As a multifunctional wire tightener for power construction that effectively solves the problem of pulling long cables, is applicable to different force directions, and simplifies the difficulty of fixing and connection, the specific implementation manners are as follows:

[0018] The operator first needs to fix one end of the device by hanging it with a hook. If it is for cable connection, the following steps are adopted: Rotate the rotating flap so that the fixing mechanism part approaches the cable. After the cable end is selected and wound around the connecting groove on the fixed clamping plate once, it is pointed from the gap between the rotating cam and the clamping block towards the rotating rod direction. Then, after continuing to pass through between the two groups of rotating rods, the rotating through hole is rotated by means of a wrench or the like to drive the rotation of the rotating disc. Then, after the cable is completely tightened and surrounds the connecting groove of the rotating cam, the cable end is pulled to move in the reverse direction along the wire inlet. The friction between the cable and the connecting groove drives the rotation of the rotating cam and simultaneously compresses the gap between the rotating cam and the connecting groove, so that the cable is completely clamped between the rotating cam and the clamping block to complete the fixing. If it needs to be removed later, just continue to rotate the rotating disc. The excess cable pulls the rotating cam to rotate in the reverse direction and gets out of the extrusion;

[0019] After completion of fixation, wind the cable to be connected around between the clamping rings once, then bend one end of the power column and the push rod, keep the power column and the push rod at the other end straight. After that, swing the push rod at the bent end. During the swinging process of the push rod at the bent end, the moving tube rotates. After stopping, the inclined surface fixing tube in the moving through hole stays between the two groups of movable triangular blocks. Due to the adsorption effect of the magnetic force restraint ring, one of the movable triangular blocks always fits against the inner wall of the magnetic force restraint ring under the rotation action of the rotating shaft rod. The reverse rotation of the moving tube further prevents the moving tube from rotating in the reverse direction due to the frictional force of the cable, forming a ratchet effect. At the same time, when the moving tube rotates, after the clamping ring passes through the triangular wedge block, the sliding fixing rod on the clamping ring disengages from the fixed ring, and the clamping ring slowly moves towards the midpoint of the winding shaft. Grooves can be added to the relative side of the clamping ring to increase the frictional force to prevent the cable from detaching. The cable in the middle is clamped by the clamping ring and winds around the winding shaft and then flows out of the winding shaft. Continuing to rotate the power column can achieve cyclic pulling of the cable for tightening, and at the same time, it will not wind around the winding shaft, solving the problem of tightening long cables; if connecting a shorter cable, there is no need to worry about the problem of cable winding. Just rotate the fixing screw and fit one side of the triangular wedge block against the fixed clamping plate, so that the clamping ring will not move, and then it can be normally fixed and the cable can be tightened by rotation;

[0020] After completion of cable tightening, if it is necessary to remove the device, bend the previously vertical push rod, and the other end becomes vertical instead. The push rod being bent is supported by the support bracket, causing the power column to move within the moving tube. During the movement of the guiding rod, the movable ring groove at one end of the power column far from the previously swinging push rod squeezes the inclined surface fixing tube to protrude out of the moving through hole, causing the inclined surface fixing tube to abut against the middle outer periphery side of the power column flowing from the movable ring groove. The other end will be the opposite. The above operations cause the restraint direction of the inclined surface fixing tube by the movable triangular blocks to change, causing the original rotation direction of the ratchet fixation to reverse. Then, continue to swing the push rod to make the cable clamped by the clamping ring disengage from the winding shaft, completing the disassembly. At the same time, the ratchet effect in this direction can also be achieved, which can be used for the next time or can also solve problems such as different hand usage habits by changing the movement direction and performing the above operations.

[0021] In the above way, during the swinging process, hold and rotate the rotating sleeve rod at the other end to prevent the device from rotating by itself, effectively solving the operation safety problem.

[0022] The device has a simple structure. Through a simple connection structure, it effectively solves the problem of pulling long cables. At the same time, it simplifies the connection method of the end fixing, is convenient for adapting to different force directions, prevents the device from rotating by itself and affecting the operation safety, and can also solve problems such as different hand usage habits. It has good practicability and economy, which is beneficial to the popularization and use of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The triangular wedge block 43 abuts the adjacent clamping ring 42; Advantageously, a moving tube 17 is provided in the middle of the wire winding shaft 13. The outer peripheral side of the moving tube 17 abuts the inner cavity side of the wire winding shaft 13. A number of fixed slots 131 are provided on the inner cavity side of the wire winding shaft 13. The number of fixed slots 131 is arranged in a circular array. A number of movable pin rods 172 are provided on the outer peripheral side of the moving tube 17. Specifically, the quantity depends on the actual situation. The movable pins penetrate and are slidably connected to the fixed slots 131. Selection members are provided on the outer sides of the two groups of fixed clamping plates 11. The two groups of selection members are arranged in a circular array to assist in changing the rotation direction of the moving tube 17; Specifically, the selection member includes a magnetic force constraint ring 14. The moving tube 17 passes through the center of the magnetic force constraint ring 14. A number of movable triangular blocks 141 are provided between the moving tube 17 and the moving tube 17. The rotating shaft rod 142 has a right triangular prism structure. One right-angled side surface of the movable triangular block 141 abuts the inner cavity side of the magnetic force constraint ring 14. A number of movable triangular blocks 141 are arranged in a circular array in the inner cavity of the magnetic force constraint ring 14. A circular ring cover plate 15 is provided on the side of the magnetic force constraint ring 14 away from the fixed clamping plate 11. Rotating shaft rods 142 are provided on both sides of the movable triangular block 141 close to the right-angled end. The rotating shaft rods 142 are rotatably connected to the circular ring cover plate 15. Advantageously, a number of movable through holes 173 are provided at both ends of the moving tube 17. The number of movable through holes 173 is arranged in a circular array on the outer peripheral side of the moving tube 17. Inclined surface fixing tubes 171 are provided in the movable through holes 173. One inclined surface fixing tube 171 at one end of the moving tube 17 passes into the gap between the two groups of movable triangular blocks 141. The end of the inclined surface fixing tube 171 at the other end of the moving tube 17 away from the axis of the moving tube 17 abuts the inner cavity of the moving tube 17. An inclined surface is provided on one side of the fixed slot 131 close to the midpoint of the moving tube 17. Advantageously, a power column 16 is slidably connected in the middle of the moving tube 17. Moving ring grooves 163 are provided at both ends of the power column 16. The other end of the inclined surface fixing tube 171 abutting the inner cavity side of the moving tube 17 abuts the moving ring grooves 163;

[0040] In implementation, after winding the cable to be pulled between the clamping rings 42 for one turn, bend one end of the power column 16 and the push rod 18, and keep the power column 16 and the push rod 18 at the other end straight. Then swing the push rod 18 at the bent end. During the swinging process of the push rod 18 at the bent end, the moving tube 17 rotates. After stopping, the inclined surface fixed tube 171 in the movable through hole 173 stays between the two groups of movable triangular blocks 141. Due to the adsorption effect of the magnetic force constraint ring 14, one of the movable triangular blocks 141 always fits against the inner wall of the magnetic force constraint ring 14 under the rotation of the rotating shaft rod 142. The reverse rotation of the moving tube 17 further prevents the moving tube 17 from rotating reversely due to the frictional force of the cable, forming a ratchet effect. At the same time, when the moving tube 17 rotates, after the clamping ring 42 passes through the triangular wedge block 43, the sliding fixed rod 421 on the clamping ring 42 disengages from the fixed ring 41, and the clamping ring 42 slowly moves towards the midpoint of the winding shaft 13. Grooves can be added to the opposite side of the clamping ring 42 to increase the frictional force to prevent the cable from detaching. The cable in the middle is clamped by the clamping ring 42, winds around the winding shaft 13 and then flows out of the winding shaft 13. Continuing to rotate the power column 16 can realize the cyclic pulling of the cable for fastening, and at the same time, it will not wind around the winding shaft 13, solving the problem of fastening long cables.

[0041] Beneficially, extension blocks 161 are provided at both ends of the movable ring groove 163. A rotating rod 162 is provided on the extension block 161. A push rod 18 with a rotating connection is provided on the rotating rod 162. A rotating sleeve rod 181 is provided on the push rod 18. The rotating sleeve rod 181 is sleeved on the push rod 18. A support bracket 12 is provided on the side of the fixed clamping plate 11 away from the magnetic force constraint ring 14 to assist the push rod 18 in prying the power column 16 to slide in the moving tube 17.

[0042] Hook 2 is provided at both ends of the wire pulling mechanism to assist in fixing the position of the wire pulling mechanism. Since Hook 2 is a standard part, it will not be elaborated here. A fixing mechanism 3 is also provided between Hook 2 and the wire pulling mechanism. The fixing mechanism 3 includes a rotating flap. Rotating round rods 221 are provided at both ends of the rotating flap. The end of Hook 2 is rotatably connected to the rotating flap 22. Extension columns 21 are also provided at both ends of the rotating flap 22. One end of the extension column 21 is rotatably connected to the rotating round rod 221, and the other end of the extension column 21 away from the rotating flap is fixedly connected to the adjacent fixing clamp 11. The fixing mechanism 3 further includes a clamping block 31. The clamping block 31 has a C-shaped structure. A rotating cam 311 is provided in the middle of the clamping block 31. A connecting groove 312 is provided on the outer peripheral side of the rotating cam 311. The rotating cam 311 is rotatably connected to both ends of the clamping block 31. A fixing connecting rod 222 is provided between the clamping block 31 and the rotating flap. Two groups of rotating rods 34 are provided at the end of the clamping block 31 away from the clamping block 31. Rotating discs 33 are provided at both ends of the two groups of rotating rods 34. The rotating rods 34 are rotatably connected to the rotating discs 33. A rotating through hole 331 is provided in the middle of the rotating disc 33. An extension plate 32 is provided between the rotating disc 33 and the clamping block 31. The rotating disc 33 is rotatably connected to the extension plate 32.

[0043] In implementation, rotate the rotating flap so that part of the fixing mechanism 3 approaches the cable. After that, insert the cable end into the connecting groove 312 on the fixing clamp 11 in a circle, and then point it from the gap between the rotating cam 311 and the clamping block 31 towards the rotating rods 34. Then continue to pass it between the two groups of rotating rods 34. After that, rotate the rotating through hole 331 by means of a wrench or the like to drive the rotating disc 33 to rotate. After that, when the cable is completely tightened around the connecting groove 312 of the rotating cam 311, pull the cable end to move in the reverse direction along the cable entry point. The frictional force between the cable and the connecting groove 312 drives the rotating cam 311 to rotate while compressing the gap between the rotating cam 311 and the connecting groove 312, so that the cable is completely clamped between the rotating cam 311 and the clamping block 31 to complete the fixation. If it needs to be removed later, just continue to rotate the rotating disc 33. The excess cable pulls the rotating cam 311 to rotate in the reverse direction to disengage from the extrusion.

[0044] Beneficially, guide rods 19 are provided at both ends of the two groups of fixing clamps 11. A guide notch ring 191 is provided between the two adjacent guide rods 19. The middle of the guide notch ring 191 abuts against the guide rod 19. After passing the cable into the notch of the guide notch ring 191, rotate the guide notch ring 191 so that the notch of the guide notch ring 191 points to the middle of the guide rod 19, and the guiding constraint of the cable towards the winding shaft 13 can be realized.

[0045] The working principle of the present invention:

[0046] First, the operator needs to fix one end of the device by hanging it with the hook 2. If it is a cable connection, the following steps are adopted: Rotate the rotating flap so that the fixing mechanism 3 approaches the cable. Then, after inserting the cable end into the connection groove 312 on the fixing clamp 11 for one circle, it points towards the rotating rod 34 from the gap between the rotating cam 311 and the clamping block 31. Then, after continuing to pass through between the two groups of rotating rods 34, rotate the rotating through-hole 331 by means of a wrench or the like to drive the rotation of the rotating disk 33. Then, after the cable is completely tightened around the connection groove 312 of the rotating cam 311, pull the cable end to move in the reverse direction along the cable inlet. The frictional force between the cable and the connection groove 312 drives the rotation of the rotating cam 311 and simultaneously compresses the gap between the rotating cam 311 and the connection groove 312, so that the cable is completely clamped between the rotating cam 311 and the clamping block 31 to complete the fixation. If it needs to be removed later, just continue to rotate the rotating disk 33. Pulling the excess cable rotates the rotating cam 311 in the reverse direction to disengage from the extrusion;

[0047] After the fixation is completed, wind the cable to be pulled between the clamping rings 42 for one circle. Then, bend one end of the power column 16 and the push rod 18, and keep the power column 16 and the push rod 18 at the other end straight. Then, swing the push rod 18 at the bent end. During the swinging process of the push rod 18 at the bent end, the moving tube 17 rotates. After stopping, the inclined surface fixing tube 171 in the moving through-hole 173 stays between the two groups of movable triangular blocks 141. Due to the adsorption effect of the magnetic restraint ring 14, one side of the movable triangular block 141 always fits against the inner wall of the magnetic restraint ring 14 under the rotation action of the rotating shaft rod 142. The reverse rotation of the moving tube 17 further prevents the moving tube 17 from rotating in the reverse direction due to the frictional force of the cable, forming a ratchet effect. At the same time, when the moving tube 17 rotates, after the clamping ring 42 passes through the triangular wedge block 43, the sliding fixing rod 421 on the clamping ring 42 disengages from the fixing ring 41, and the clamping ring 42 slowly moves towards the midpoint of the winding shaft 13. Grooves can be added to the opposite side of the clamping ring 42 to increase the frictional force to prevent the cable from disengaging. The cable in the middle is clamped by the clamping ring 42 and winds around the winding shaft 13 and then flows out of the winding shaft 13. Continuing to rotate the power column 16 can realize the cyclic pulling of the cable for tightening, and at the same time, it will not wind around the winding shaft 13, solving the problem of tightening long cables; If it is a short cable connection and there is no need to worry about the problem of cable winding, just rotate the fixing screw 431 to make one side of the triangular wedge block 43 fit against the fixing clamp 11, so that the clamping ring 42 will not move, and then it can be normally fixed and the cable can be tightened by rotation;

[0048] After the tight wire is completed and the device needs to be removed, push the vertical push rod 18 before bending, and the other end turns vertical. The push rod 18 for bending is supported by the support bracket 12, so that the power column 16 moves in the moving pipe 17. During the movement of the wire rod 19, the movable ring groove 163 at one end of the power column 16 away from the previous swinging push rod 18 squeezes the inclined surface fixed pipe 171 protruding from the movable through hole 173, so that the inclined surface fixed pipe 171 abuts against the middle outer periphery side of the power column 16 flowing from the movable ring groove 163, and the other end will be the opposite. The above operations cause the constraint direction of the inclined surface fixed pipe 171 by the movable triangular block 141 to change, so that the original rotation direction of the ratchet fixation changes in the reverse direction. Then, the push rod 18 can be continuously swung to make the cable clamped by the clamping ring 42 break away from the winding shaft 13, completing the disassembly. At the same time, the ratchet effect in this direction can also be realized, which can be used next time or can also solve problems such as different hand habits and change the movement direction to perform the above operations.

[0049] In the above way, during the swinging process, hold the rotating sleeve rod at the other end to prevent the device from rotating automatically, effectively solving the operation safety problem.
