Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to an electric power construction pay-off frame. Background Art

[0002] Power construction refers to construction projects related to the production, transmission and distribution of electric energy. Electric energy is widely used in production and life. Electric energy is usually transmitted using wires. However, thicker cables are heavier during construction, so special pay-out racks are used to lay out the cables during power construction.

[0003] For example, a Chinese utility model patent with patent number CN220148828U provides a wire-laying frame for power construction, including a base plate, the top of which is respectively fixedly connected to a first support rod group and a second support rod group, the outer surfaces of the first support rod group and the second support rod group are slidably connected to sleeve rods, the inner wall of the sleeve rod is fixedly connected to a support plate, and the inside of the support plate is fixedly connected to a swivel.

[0004] Although the above device solves the problem of inconvenience in timely braking of the pay-off shaft, the device cannot automatically lift the heavy cable reel and place it on the pay-off shaft. Therefore, workers usually need to expend a lot of physical strength to manually lift the cable reel, or rely on bulky cranes for assistance, which leads to low efficiency of power construction; in addition, the device cannot adapt to cable reels of different sizes, resulting in a relatively single use. Utility Model Content

[0005] The utility model discloses an electric power construction pay-off stand, which solves the problems that the traditional electric power construction pay-off stand cannot automatically lift the heavy cable reel and place it on the pay-off shaft, resulting in low efficiency of electric power construction, and cannot adapt to cable reels of different sizes, resulting in relatively single use.

[0006] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0007] The lifting of the ...

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] Start the electric push rod, so that the end of the inclined plate that is not connected to the bottom plate contacts the ground. The staff only needs to use the inclined plate to roll the cable drum to the middle of the two support columns, and then use the first drive component to drive the two support columns closer to each other, so that the support shaft and the fixed plate on the surface of the support shaft are inserted into the middle hollow of the cable drum, and the two ends of the cable drum are in contact with the limit ring; then, use the second drive component to drive the fixed plate to move in the direction away from the support shaft, and make the fixed plate contact with the inner wall of the cable drum to achieve effective fixation of cable drums of different sizes; finally, start the hydraulic cylinder to drive the support shaft to move upward, thereby driving the cable drum to move to a suitable position, and the wire laying operation can be performed. The utility model can lift the cable drum and move it to a suitable position without the staff manually lifting the cable drum or relying on auxiliary equipment by setting the inclined plate, electric push rod, support shaft and hydraulic cylinder, saving time and effort; at the same time, by setting the first drive component, limit ring, fixed plate and second drive component, cable drums of different sizes can be fixed, making the use of the entire device more flexible.

The supporting shaft 3 is provided with a second driving component for driving the fixing plates 4 to move closer to or away from the supporting shaft 3. An inclined plate 11 is hinged at one end edge of the bottom plate 1, and an electric push rod 12 for driving the inclined plate 11 to rotate around the hinge is provided on the bottom plate 1. The fixed end and the telescopic end of the electric push rod 12 are respectively hinged to the opposite side of the bottom plate 1 and the inclined plate 11.

[0018] like Figure 3As shown, the support column 2 is fixed with slide rails 22 located on both sides of the inner groove 21, and the surface of the support shaft 3 is fixed with a block 32 corresponding to the slide rail 22. The block 32 can surround the support shaft 3, and the block 32 and the bottom of the support shaft 3 are fixedly connected to the output end of the hydraulic cylinder 31. After the hydraulic cylinder 31 is started, the output end of the hydraulic cylinder 31 pushes the block 32 to move along the slide rail 22, which can drive the support shaft 3 fixedly connected to the block 32 to move, thereby raising the cable drum to facilitate the wire laying operation. By setting the slide rail 22 and the block 32, the support shaft 3 can be well supported and limited and guided, effectively improving the stability of the support shaft 3 when moving.

[0020] like Figure 2 As shown, the first driving assembly includes a first motor 5 fixed inside the base plate 1, a horizontal bidirectional screw rod 51 is fixed at the output end of the first motor 5, two symmetrical sliders 23 are sleeved on the bidirectional screw rod 51, and the two sliders 23 are respectively fixedly connected to the bottom surfaces of the two support columns 2, and a cavity 13 for the sliders 23 to move is provided on the base plate 1. After placing the cable drum between the two support columns 2, the first motor 5 is started, and the output end of the first motor 5 drives the bidirectional screw rod 51 to rotate, thereby driving the two sliders 23 to move in a direction of approaching or moving away from each other, so that the distance between the two support columns 2 can be adjusted, thereby achieving the fixation of cable drums of different lengths.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a fixing seat 6 far away from the inclined plate 11 is fixed at the center axis of the top surface of the bottom plate 1, and two symmetrical and vertical arc plates 7 are movably arranged above the fixing seat 6, and the concave surfaces of the two arc plates 7 are arranged oppositely.

[0025] like Figure 1As shown, a universal wheel 14 is fixed to the bottom of the base plate 1. The universal wheel 14 adopts a universal wheel 14 with a self-locking function, which is convenient for the staff to move and fix the entire device.

[0026] When in use, start the electric push rod 12 so that the end of the inclined plate 11 that is not connected to the bottom plate 1 is in contact with the ground. The staff only needs to use the inclined plate 11 to roll the cable drum to the middle of the two support columns 2, and then start the first motor 5. The output end of the first motor 5 drives the bidirectional screw rod 51 to rotate, thereby driving the two sliders 23 to move in the direction of approaching or moving away from each other, so that the distance between the two support columns 2 can be adjusted, so that the support shaft 3 and the fixing plate 4 on the surface of the support shaft 3 are both inserted into the middle hollow of the cable drum, and the two ends of the cable drum are in contact with the limit ring 33; then, start the automatic push rod 41, and the output end of the automatic push rod 41 pushes the fixing plate 4 to move in the direction away from the support shaft 3, so that the arc-shaped fixing plate 4 fits perfectly with the inner wall of the cable drum, thereby achieving different sizes. The cable drum is effectively fixed; then, the hydraulic cylinder 31 is started, and the output end of the hydraulic cylinder 31 pushes the block 32 to move along the slide rail 22, which can drive the support shaft 3 fixedly connected to the block 32 to move, so that the cable drum is lifted to facilitate the wire-laying operation and is easier to carry out; when laying out the wire, the cable is first passed through the ring 61, and the displacement sensor 9 is used to monitor the length of the cable laying out. When a certain length is reached, the second motor 8 is started, and the output end of the second motor 8 drives the bidirectional screw 81 to rotate through the pulley 82 and the transmission belt 83, which can drive the two limit blocks 72 to approach each other, thereby realizing the clamping and fixing of the cable by the two arc plates 7 through the connecting rod 71, effectively avoiding the waste of the cable caused by the staff continuing to pull the cable, and achieving the purpose of accurately controlling the length of the cable laying out.
