[0002] Cable pay-off machines are widely used in industries such as power, communication, and construction, and are key equipment for realizing the efficient and safe laying of power cables, optical cables, and communication cables. Traditional cable laying methods mainly rely on manual operation, which not only has a large labor intensity and long duration, but also is difficult to ensure the neatness and beauty of the laying. At the same time, in humid or complex environments, the safety of manual laying cannot be effectively guaranteed.

[0003] With the development of technology, modern power, communication, and construction fields have put forward higher requirements for the efficiency and safety of cable laying. Cable pay-off machines can significantly improve the efficiency of cable laying, reduce labor costs, ensure laying accuracy, and simplify the construction process.

[0019] 1. By providing a guiding mechanism, the device can fix the cable at the wellhead position by using the first clamping plate and the second clamping plate, which can avoid unnecessary movement or detachment of the cable during operation, reduce the accident risk.

Specific embodiments

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Refer to Figures 1 to 8 , a cable unreeling machine in this embodiment includes a mounting bracket 10. A guiding mechanism 20 for preventing the cable from rubbing against the wellhead is arranged at the front of the mounting bracket 10. A lifting mechanism 30 for fixing the guiding mechanism 20 at the wellhead is arranged between the mounting bracket 10 and the guiding mechanism 20. An anti - detachment mechanism 40 for preventing the cable from falling off is arranged on the surface of the guiding mechanism 20. A placing mechanism 50 for fixing the cable reel is arranged at the bottom of the mounting bracket 10. An ejecting mechanism 60 for assisting in removing the cable reel is arranged inside the placing mechanism 50.

[0036] The guiding mechanism 20 includes symmetrically arranged first clamping plate 201 and second clamping plate 202. A sliding rod 204 is slidably connected to the side of the first clamping plate 201. A sleeve 203 is slidably sleeved outside the sliding rod 204. One end of the sleeve 203 away from the sliding rod 204 is fixedly connected to the side of the second clamping plate 202. Guiding wheels 207 are fixedly connected to the top of the first clamping plate 201 and the bottom of the second clamping plate 202.

[0037] The guiding mechanism 20 further includes a plurality of positioning holes 206 formed on the surface of the sliding rod 204. A fixing pin 205 is slidably inserted into the surface of the sleeve 203, and the fixing pin 205 slidably penetrates through one of the positioning holes 206.

[0038] One end of the sliding rod 204 away from the sleeve 203 is fixedly connected with a triangular block 208. A first spring 209 is also sleeved outside the sliding rod 204. The first spring 209 is located outside the sliding rod 204 between the first clamping plate 201 and the triangular block 208, and both the first clamping plate 201 and the second clamping plate 202 are in an L-shaped structure.

[0039] During specific operation, first, roughly adjust the distance between the first clamping plate 201 and the second clamping plate 202 according to the diameter of the wellhead. When adjusting, first pull out the fixing pin 205, then pull the sleeve 203 to slide along the surface of the sliding rod 204, and then insert the fixing pin 205 back to its original position, so that the fixing pin 205 passes through one of the positioning holes 206 to fix the distance between the first clamping plate 201 and the second clamping plate 202. At this time, the distance between the first clamping plate 201 and the second clamping plate 202 is slightly smaller than the diameter of the wellhead. Control the first clamping plate 201 and the second clamping plate 202 to descend through the lifting mechanism 30, so that the first clamping plate 201 and the second clamping plate 202 are attached to the top of the wellhead. When the first clamping plate 201 descends and fits on the wellhead, the side of the wellhead squeezes the inclined surface of the triangular block 208, so as to drive the sliding rod 204 through the triangular block 208 to push the second clamping plate 202 away from the first clamping plate 201, thereby supporting and fixing the first clamping plate 201 and the second clamping plate 202 on the wellhead. Finally, pull the cable along the guide wheel 207 on the top of the first clamping plate 201, so that the cable continues to slide along the surface of the guide wheel 207 at the bottom of the second clamping plate 202, which can avoid unnecessary movement or detachment of the cable during the operation process, reduce the accident risk, and the use of the guide wheel 207 can ensure that the cable slides along a predetermined path, reducing the chance of direct friction between the cable and the well wall or other hard objects, thereby reducing the risk of cable wear.

[0040] When removing the first clamping plate 201 and the second clamping plate 202 from the wellhead, drive the first clamping plate 201 and the second clamping plate 202 to rise through the lifting mechanism 30. At this time, the side of the wellhead releases the extrusion on the triangular block 208. Under the push of the first spring 209, the first clamping plate 201 and the second clamping plate 202 approach each other, and the distance between the first clamping plate 201 and the second clamping plate 202 decreases. Then the first clamping plate 201 and the second clamping plate 202 can be detached from the wellhead.

[0041] The lifting mechanism 30 includes a moving rod 302 fixedly connected to the side of the first clamping plate 201. A fixing rod 301 is slidably sleeved outside the moving rod 302, and the side of the fixing rod 301 is fixedly connected to the mounting frame 10.

[0042] The lifting mechanism 30 includes a fixed plate 304 fixedly connected inside the cavity of the fixed rod 301. A rotating lead screw 303 is rotatably connected to the middle of the fixed plate 304. The bottom of the rotating lead screw 303 is threadedly connected to the top of the moving rod 302. The extended end of the top of the rotating lead screw 303 is fixedly connected with a first bevel gear 305. The fixed rod 301 is horizontally rotatably connected with a transmission shaft 307. A second bevel gear 306 is fixedly connected to the outside of the transmission shaft 307. The second bevel gear 306 meshes with the first bevel gear 305. One end of the transmission shaft 307 is fixedly connected with a hand wheel 308.

[0043] During specific operation, when the guiding mechanism 20 needs to be fitted and fixed at the wellhead, rotate the hand wheel 308 to drive the transmission shaft 307 to rotate. The transmission shaft 307 drives the first bevel gear 305 to rotate through the second bevel gear 306. The first bevel gear 305 drives the rotating lead screw 303 to rotate in the middle of the fixed plate 304. When the rotating lead screw 303 rotates, the moving rod 302 is pushed out of the cavity of the fixed rod 301. The moving rod 302 drives the first clamping plate 201 to move synchronously, align the first clamping plate 201 and the second clamping plate 202 with the wellhead, and then fit and fix the first clamping plate 201 and the second clamping plate 202 at the wellhead.

[0044] When the guiding mechanism 20 needs to be detached from the wellhead, rotate the hand wheel 308 in the reverse direction, pull the moving rod 302 upward from the cavity of the fixed rod 301, so as to drive the first clamping plate 201 and the second clamping plate 202 to be detached from the wellhead.

[0045] The anti - detachment mechanism 40 includes a first guiding rod 401 fixedly connected to the top of the first clamping plate 201. A moving block 402 is slidably connected to the outside of the first guiding rod 401. An extrusion roller 403 is rotatably connected to the side of the moving block 402. A limiting block 405 is fixedly connected to the top of the first guiding rod 401. A second spring 404 is sleeved on the outside of the first guiding rod 401 between the limiting block 405 and the moving block 402. The same anti - detachment mechanism 40 is provided at the bottom of the second clamping plate 202.

[0046] During specific operation, after the cable is placed on the surface of the guiding wheel 207, the elastic force of the second spring 404 pushes the moving block 402 to move along the first guiding rod 401 towards the guiding wheel 207. The extrusion roller 403 can ensure that the cable is firmly attached to the guiding wheel 207, effectively avoiding the situation that the cable falls off the guiding wheel 207 due to accidental sliding or jumping during the operation. The extrusion roller 403 and the guiding wheel 207 work together to make the cable slide smoothly along the predetermined path, reducing the friction between the cable and other hard objects and potential mechanical damage.

[0047] The placing mechanism 50 includes a support base 501 fixedly connected to the bottom of the mounting frame 10. The bottom of the support base 501 is fixedly connected with moving wheels. The top of the support base 501 is fixedly connected with a placing frame 502. The top of the placing frame 502 is symmetrically and rotatably connected with rotating rods 503. Notches 504 are symmetrically formed on the outside of each rotating rod 503. Baffles 507 are symmetrically and slidably sleeved on the outside of each rotating rod 503.

[0048] Each placing frame 502 internally rotatably connects a bidirectional lead screw 505. The two ends of the bidirectional lead screw 505 are respectively threadedly connected with connecting plates 508. Each connecting plate 508 extends from the notch 504 to the outside of the rotating rod 503. One end of the connecting plate 508 away from the bidirectional lead screw 505 is fixedly connected with the baffle 507. One ends of the two bidirectional lead screws 505 are both fixedly connected with belt pulleys 510. The two belt pulleys 510 are drivingly connected by a synchronous belt 511. The extended end of one of the bidirectional lead screws 505 is fixedly connected with a crank 506. A dial rod 509 for blocking the rotation of the rotating rod 503 is fixedly connected to the outside of the rotating rod 503.

[0049] During specific work, when in use, place the cable reel between the two rotating rods 503. Then, block the dial rod 509 with one hand to prevent the rotating rod 503 from rotating. Then, turn the crank 506 with the other hand to drive the bidirectional lead screw 505 to rotate. When the bidirectional lead screw 505 rotates, it drives the two connecting plates 508 to approach each other. The two connecting plates 508 drive the two baffles 507 to fit against the side of the cable reel, thereby realizing the limit of the cable reel and preventing the cable reel from shifting during the process of releasing the cable. The cable reel can smoothly release the cable as the rotating rod rotates, reducing the resistance and jamming during the cable release process and making the cable laying smoother.

[0050] The ejection mechanism 60 includes a rotating rod 601 rotatably connected to the placing frame 502. Torsion springs 602 are symmetrically sleeved on the outside of the rotating rod 601. One end of each torsion spring 602 is fixedly connected to the rotating rod 601, and the other end of the torsion spring 602 is fixedly connected to the placing frame 502. A U-shaped rod 603 is fixedly connected to the side of the rotating rod 601. Second guide rods 608 are slidably connected to the sides of the placing frame 502 on both sides of the U-shaped rod 603. Moving seats 604 are fixedly connected to one ends of the two second guide rods 608 close to each other. A block 605 for restricting the rotation of the U-shaped rod 603 is fixedly connected to the side of the moving seat 604 close to the U-shaped rod 603, and an inclined surface is formed on the top of the block 605.

[0051] A push plate 606 is fixedly connected to the top of the moving seat 604. The top of the push plate 606 is located on the side of the baffle 507. A metal elastic sheet 607 is fixedly connected to the side of the moving seat 604 away from the block 605. One end of the metal elastic sheet 607 away from the moving seat 604 is slidably abutted against the side of the placing frame 502.

[0052] During specific operation, after the cable on the cable reel is completely released, the crank 506 needs to be rotated reversely to drive the bidirectional lead screw 505 to rotate synchronously in the reverse direction, so that the two baffles 507 move away from the cable reel, first releasing the limit of the cable reel by the baffles 507. Then, continue to rotate the crank 506 reversely, so that the baffle 507 continues to approach the side of the placement rack 502. The baffle 507 contacts the push plate 606, and the baffle 507 pushes the push plate 606 to approach the side of the placement rack 502. The push plate 606 drives the moving seat 604 to approach the side of the placement rack 502 synchronously. The moving seat 604 and the placement rack 502 compress and store energy in the metal elastic sheet 607. The moving seat 604 drives the block 605 to disengage from the top of the U-shaped rod 603. Driven by the torsion of the torsion spring 602, the rotating rod 601 drives the U-shaped rod 603 to rotate upward. The rotating U-shaped rod 603 ejects the cable reel from between the two rotating rods 503, realizing the rapid removal of the cable reel and facilitating the rapid replacement of the cable reel.

[0053] When replacing the cable reel with a new one, first push the U-shaped rod 603 so that the U-shaped rod 603 is fixed by the block 605. The metal elastic sheet 607 pushes the moving seat 604 to approach the U-shaped rod 603, so that the block 605 is stuck on the top of the U-shaped rod 603.

[0054] Working principle:

[0055] The support base 501 with moving wheels drives the entire device to move, enabling the guiding mechanism 20 to be aligned at the wellhead. The lifting mechanism 30 drives the guiding mechanism 20 to fit at the wellhead. The guiding mechanism 20 is used to guide the cable. Then, the cable reel is placed in the placement mechanism 50. The cable reel can smoothly release the cable as the rotating rod 503 rotates, reducing the resistance and jamming during the cable release process, making the cable laying smoother. After the cable reel releases the cable, the placement mechanism 50 drives the ejection mechanism 60 to push the cable reel down from between the two rotating rods 503, realizing the rapid replacement of the cable reel.
