Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a cable erection, installation and tensioning device. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. When the cable is erected and installed, it is inevitable to tighten the cable to connect the cables. However, if the cable is tightened directly by manual labor, it will consume a lot of physical energy. Therefore, a tensioning device is needed.

[0003] For example, a tensioning device for cable installation disclosed in publication number CN115621908A relates to the field of cable installation technology and includes: a carrier, a tensioning shaft body being rotatably mounted on the front side of the carrier; a transmission member being provided at the left front end of the carrier, and the transmission member being in an "L"-shaped structure; a swinging shaft body being rotatably mounted at the right front end of the carrier; and a handwheel being provided on the tensioning shaft body located below. This invention adds a push tensioning mechanism on the basis of rotary tensioning, and ensures the tensioning effect of the cable through the reasonable coordination of the two mechanisms. At the same time, the two mechanisms can be synchronously operated by rotating the handwheel, so that the two mechanisms synchronously tighten the cable, ensuring the tensioning efficiency of the cable. There is no need for manual separate operation or equipping the two mechanisms with separate electric drive devices. This solves the problem that most existing devices rely solely on manually rotating winches or similar items to tighten the cable, which results in a single cable tensioning method and low tensioning efficiency.

[0019] 3. This type of cable installation and tensioning device, when the wire is inserted into the wire hole, the support spring supports the sliding seat, and the sliding seat supports the clamping rod through the movable support rod, so that the clamping wheel at one end of the clamping rod fits with both sides of the cable, so that cables of different widths can always be kept in the middle of the wire hole, which enhances the winding and tightening effect and can further prevent the cable from being entangled and knotted.

[0040] In this embodiment, when the winding rod 120 rotates, it drives the rotating disk 110 to rotate, and the second rotating block 150 of the rotating disk 110 rotates. The adjusting rod 520 supports the staggered toothed disk 521 under the action of the clamping spring 530. The staggered toothed disk 521 is engaged with the staggered gear 151.

The ratchet Under the action of the movable block 512, the ratchet 510 cannot rotate in the opposite direction, and the adjusting rod 520, the second rotating block 150 and the winding rod 120 cannot rotate in the opposite direction, thereby enhancing the tensioning effect of the cable. When the cable needs to be loosened, the user pulls the adjusting rod 520 downward through the handle 523, and the adjusting rod 520 drives the offset toothed disc 521 to move downward and disengage from the offset gear 151, so that the second rotating block 150 and the winding rod 120 can rotate in the opposite direction, thereby achieving the effect of releasing the line.

[0041] Working principle: The user can place the tensioning housing 100 on one side of the electric pole, and the user rotates one of the double-thread screws 410 by the handle. The two double-thread screws 410 rotate synchronously under the action of the transmission sprocket and the transmission chain. The movable screw sleeve 411 moves in the opposite direction along the double-thread screw 410 under the action of the thread, so that the clamping seat 400 clamps the electric pole, thereby facilitating the installation and removal of the tensioning housing 100. One end of the cable is inserted into the inside of the clamping hole 121 through the wire hole 301 on the wire seat 300. The user pulls the adjusting ring 125 upwards, and the adjusting ring 125 drives the movable block 129 to move in the movable position through the slider 126. The internal movement of the movable groove 122 compresses the compression spring 128, causing the clamping rod 127 to retract into the inside of the clamping hole 121. The user inserts one end of the cable into the inside of the clamping hole 121, and the user loosens the adjusting ring 125. The clamping rod 127 and the movable block 129 move downward under the action of the compression spring 128, so that the clamping rod 127 clamps one end of the cable, so that the cable is limited in the inside of the clamping hole 121, thereby facilitating the winding rod 120 to rotate the cable. The user can rotate the rotating plate 131 through the grip 132, and the rotating plate 131 drives the upper rotating disk 110 to rotate through the first rotating block 140, so that the winding rod 120 rotates. When the cable is wound and tightened, when the first rotating block 140 rotates, the first rotating block 140 drives the reciprocating screw rod 210 to rotate through the transmission sprocket and the transmission chain, so that the wire seat 300 can move repeatedly along the guide rod 220, so as to evenly wind the cable on the surface of the winding rod 120, avoid the cable from getting tangled and affecting the later use. When the winding rod 120 rotates, it drives the rotating disk 110 to rotate, and the second rotating block 150 of the rotating disk 110 rotates. The adjusting rod 520 supports the staggered toothed disk 521 under the action of the fixing spring 530. The staggered toothed disk 521 is clamped with the staggered gear 151. The rotating block is connected to the staggered toothed disk 521 and the staggered gear 151. The gear 151 drives the adjusting rod 520 to rotate, and the adjusting rod 520 drives the ratchet 510 to rotate through the connecting block 513 and the connecting groove 522. Under the action of the movable block 512, the ratchet 510 cannot rotate in the opposite direction, so that the adjusting rod 520, the second rotating block 150 and the winding rod 120 cannot rotate in the opposite direction, thereby enhancing the tensioning effect of the cable. When the cable needs to be relaxed, the user pulls the adjusting rod 520 downward through the handle 523, and the adjusting rod 520 drives the offset toothed disc 521 to move downward and disengage from the offset gear 151, so that the second rotating block 150 and the winding rod 120 can rotate in the opposite direction, thereby achieving the effect of releasing the line.
