[0002] Cable laying machines are widely used in the power, communications and construction industries, and are key equipment for efficient and safe laying of power cables, optical cables and communication cables. Traditional cable laying methods mainly rely on manual operation, which is not only labor-intensive and time-consuming, but also difficult to ensure neat and beautiful laying. At the same time, in humid or complex environments, the safety of manual laying cannot be effectively guaranteed.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] See also Figures 1 to 8 A cable pay-off machine of the present embodiment includes a mounting frame 10, a guide mechanism 20 for preventing the cable from rubbing against the wellhead is arranged at the front of the mounting frame 10, a lifting mechanism 30 for fixing the guide mechanism 20 at the wellhead is arranged between the mounting frame 10 and the guide mechanism 20, an anti-dropping mechanism 40 for preventing the cable from falling off is arranged on the surface of the guide mechanism 20, a placing mechanism 50 for fixing the cable reel is arranged at the bottom of the mounting frame 10, and a pop-up mechanism 60 for assisting in removing the cable reel is arranged inside the placing mechanism 50.

[0033] The guiding mechanism 20 includes a first clamping plate 201 and a second clamping plate 202 which are symmetrically arranged. A sliding rod 204 is slidably connected to the side of the first clamping plate 201. A sleeve 203 is slidably sleeved on the outside of the sliding rod 204. The end of the sleeve 203 away from the sliding rod 204 is fixedly connected to the side of the second clamping plate 202. A guide wheel 207 is fixedly connected to the top of the first clamping plate 201 and the bottom of the second clamping plate 202.

[0034] The guide mechanism 20 further includes a plurality of positioning holes 206 opened on the surface of the slide rod 204 . A fixing pin 205 is slidably inserted into the surface of the sleeve 203 . The fixing pin 205 slides through one of the positioning holes 206 .

[0035] The end of the slide bar 204 away from the sleeve 203 is fixedly connected to a triangular block 208, and a first spring 209 is sleeved on the outside of the slide bar 204. The first spring 209 is located outside the slide bar 204 between the first clamping plate 201 and the triangular block 208, and the first clamping plate 201 and the second clamping plate 202 are both L-shaped structures.

[0036] During specific operation, firstly, the distance between the first clamping plate 201 and the second clamping plate 202 is roughly adjusted according to the diameter of the wellhead. During adjustment, the fixing pin 205 is first pulled out, and then the sleeve 203 is pulled to slide along the surface of the slide rod 204, and then the fixing pin 205 is inserted back into the original position, so that the fixing pin 205 passes through a positioning hole 206, so as 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 wellhead diameter, and the first clamping plate 201 and the second clamping plate 202 are controlled to descend by 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, and the first clamping plate 201 is lowered to fit When at the wellhead, the side of the wellhead squeezes the inclined surface of the triangular block 208, thereby driving 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 at the wellhead, and finally pulling 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 falling off of the cable during operation and reduce the risk of accidents. The use of the guide wheel 207 can ensure that the cable slides along the 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.

[0037] When the first clamping plate 201 and the second clamping plate 202 are removed from the wellhead, the first clamping plate 201 and the second clamping plate 202 are driven to rise by the lifting mechanism 30. At this time, the side of the wellhead releases the squeezing of the triangular block 208, and under the push of the first spring 209, the first clamping plate 201 and the second clamping plate 202 are moved closer to each other, and the distance between the first clamping plate 201 and the second clamping plate 202 is reduced, and then the first clamping plate 201 and the second clamping plate 202 can be detached from the wellhead.

[0038] The lifting mechanism 30 includes a moving rod 302 fixedly connected to the side of the first clamping plate 201 , a fixed rod 301 is slidably sleeved on the outside of the moving rod 302 , and a side of the fixed rod 301 is fixedly connected to the mounting frame 10 .

[0039] The lifting mechanism 30 includes a fixed plate 304 fixedly connected to the inside of the cavity of the fixed rod 301, a rotating screw 303 is rotatably connected to the middle of the fixed plate 304, the bottom of the rotating screw 303 is threadedly connected to the top of the moving rod 302, the top extended end of the rotating screw 303 is fixedly connected to the first bevel gear 305, the fixed rod 301 is horizontally rotatably connected to the transmission shaft 307, the outside of the transmission shaft 307 is fixedly connected to the second bevel gear 306, the second bevel gear 306 is meshed with the first bevel gear 305, and one end of the transmission shaft 307 is fixedly connected to a handwheel 308.

[0040] During specific work, when the guide mechanism 20 needs to be fitted and fixed on the wellhead, the hand wheel 308 is turned to drive the transmission shaft 307 to rotate, and 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 screw 303 to rotate in the middle of the fixed plate 304. When the rotating screw 303 rotates, the moving rod 302 is pushed out of the cavity of the fixed rod 301, and the moving rod 302 drives the first clamping plate 201 to move synchronously, aligning the first clamping plate 201 and the second clamping plate 202 with the wellhead, and then the first clamping plate 201 and the second clamping plate 202 are fitted and fixed on the wellhead.

[0041] When the guiding mechanism 20 needs to be separated from the wellhead, the hand wheel 308 is rotated in the opposite direction to pull the moving rod 302 upward from the cavity of the fixed rod 301, thereby driving the first clamping plate 201 and the second clamping plate 202 to separate from the wellhead.

[0042] The anti-slip mechanism 40 includes a first guide 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 guide rod 401, and the moving block 402 is rotatably connected to the side of the extrusion roller 403, a limiting block 405 is fixedly connected to the top of the first guide rod 401, a second spring 404 is sleeved on the outside of the first guide rod 401 between the limiting block 405 and the moving block 402, and the same anti-slip mechanism 40 is arranged at the bottom of the second clamping plate 202.

[0043] During specific operation, after the cable is placed on the surface of the guide wheel 207, the elastic force of the second spring 404 pushes the moving block 402 to move along the first guide rod 401 toward the guide wheel 207, and the squeezing roller 403 can ensure that the cable is firmly attached to the guide wheel 207, effectively preventing the cable from falling off the guide wheel 207 due to accidental sliding or jumping during operation. The squeezing roller 403 and the guide 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.

[0044] The placement mechanism 50 includes a support base 501 fixedly connected to the bottom of the mounting frame 10, and a movable wheel is fixedly connected to the bottom of the support base 501, a placement frame 502 is fixedly connected to the top of the support base 501, and a rotating rod 503 is symmetrically rotatably connected to the top of the placement frame 502, each rotating rod 503 is symmetrically provided with a slot 504 on the outside, and each rotating rod 503 is symmetrically slidably sleeved with a baffle 507 on the outside.

[0045] Each placement rack 502 is internally rotatably connected with a bidirectional screw rod 505, and both ends of the bidirectional screw rod 505 are respectively threadedly connected with connecting plates 508, each connecting plate 508 extends from the slot 504 to the outside of the rotating rod 503, and the connecting plate 508 is fixedly connected to the baffle 507 at one end away from the bidirectional screw rod 505, and the same end of the two bidirectional screw rods 505 is fixedly connected to a pulley 510, and the two pulleys 510 are connected by a synchronous belt 511, and the extended end of one of the bidirectional screw rods 505 is fixedly connected to a crank handle 506, and the outside of the rotating rod 503 is fixedly connected to a lever 509 for blocking the rotation of the rotating rod 503.

[0046] During specific work, when using, the cable reel is placed between the two rotating rods 503, and then one hand blocks the lever 509 to prevent the rotating rod 503 from rotating, and then the other hand turns the crank handle 506 to drive the two-way screw rod 505 to rotate. When the two-way screw rod 505 rotates, it drives the two connecting plates 508 to approach each other, and the two connecting plates 508 drive the two baffles 507 to fit against the sides of the cable reel, thereby limiting the cable reel and preventing the cable reel from shifting its position during the process of releasing the cable. The cable reel can release the cable smoothly as the rotating rod rotates, reducing the resistance and jamming during the cable release process, making the cable laying smoother.

[0047] The pop-up mechanism 60 includes a rotating rod 601 rotatably connected to the placement rack 502, and a torsion spring 602 is 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 placement rack 502. A U-shaped rod 603 is fixedly connected to the side of the rotating rod 601, and a second guide rod 608 is slidably connected to the side of the placement rack 502 on both sides of the U-shaped rod 603. The two second guide rods 608 are fixedly connected to a moving seat 604 at one end close to each other, and the moving seat 604 is fixedly connected to a block 605 for limiting the rotation of the U-shaped rod 603 on the side close to the U-shaped rod 603, and a slope is provided on the top of the block 605.

[0048] A push plate 606 is fixedly connected to the top of the movable seat 604, and the top of the push plate 606 is located on the side of the baffle 507. A metal spring 607 is fixedly connected to the side of the movable seat 604 away from the block 605. The end of the metal spring 607 away from the movable seat 604 slides against the side of the placement rack 502.

[0049] During specific operation, after the cable on the cable reel is completely released, it is necessary to rotate the crank handle 506 in the opposite direction to drive the bidirectional screw rod 505 to rotate in the opposite direction synchronously, so that the two baffles 507 are away from the cable reel. First, the limit of the baffle 507 on the cable reel is released, and then the crank handle 506 is continued to be rotated in the opposite direction to make the baffle 507 continue 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. 606 drives the moving seat 604 to move toward the side of the placement rack 502 synchronously, and the moving seat 604 and the placement rack 502 compress and store force on the metal spring 607. The moving seat 604 drives the block 605 to detach from the top of the U-shaped rod 603, and the torsion force of the torsion spring 602 drives the rotating rod 601 to drive the U-shaped rod 603 to rotate upward, and the rotating U-shaped rod 603 pushes the cable reel out from between the two rotating rods 503, so that the cable reel can be quickly removed, which is convenient for quick replacement of the cable reel.

[0050] When replacing a new cable reel, first push the U-shaped rod 603 so that the U-shaped rod 603 is fixed by the clamping block 605, and push the movable seat 604 toward the U-shaped rod 603 through the metal spring 607, so that the clamping block 605 is clamped on the top of the U-shaped rod 603.

[0051] Working principle: The entire device is moved by a support base 501 with moving wheels, so that the guide mechanism 20 can be aligned at the wellhead. The guide mechanism 20 is driven to fit at the wellhead by the lifting mechanism 30, and the cable is guided by the guide mechanism 20. After that, the cable reel is placed in the placement mechanism 50. The cable reel can release the cable smoothly as the rotating rod 503 rotates, reducing 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 pop-up mechanism 60 to push the cable reel down from between the two rotating rods 503, so as to realize the quick replacement of the cable reel.
