Description

Technical Field

[0001] The invention relates to the technical field of cable transmission, in particular to a power cable transmission traction device. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supplies for industrial and mining enterprises, and underwater transmission lines across rivers and seas. Cable laying refers to the process of laying power cables inside or outside buildings or underground. During the process of power cable laying, in order to make the installation more convenient, a special traction device is usually required to pull the cable.

[0003] After searching, the Chinese patent with publication number CN111348477B discloses a cable traction device, which belongs to the field of cable production technology, including an upper frame and a lower frame, both of which are rectangular bodies.

The upper frame is fixedly connected with an upper traction member, and the upper end face of the lower frame is provided with a lower traction member. The traction device can adjust the distance between the upper traction member and the lower traction member according to the diameter of the cable to adapt to the traction of cables of different diameters.

[0015] Preferably, two lifting plates are fixedly installed on the top wall of the base, and the side walls of the lifting plates are inclined.

The end of the linkage rotating strip away from the upper fixed plate is rotatably installed on the top position of the side wall of the adjacent upper rotating plate.

[0016] Compared with the prior art, the present invention has the following significant advantages: First, the present invention inserts the cable body into the interior of two positioning frames and between two clamping plates in an "S" shape, so that the side wall of the cable body fits with the positioning shaft and the side wall of the positioning shaft, and the worm is driven to rotate by the output end of the driving motor. The worm wheel and the worm are meshed with each other, so the worm wheel will drive the positioning shaft to rotate together, and the rotation of the positioning shaft drives the cable body to move, thereby achieving the effect of conveying and pulling the cable body. Since the cable body is distributed in an "S" shape, when the cable body is pulled, the cable body can fit more closely with the side wall of the positioning shaft, thereby ensuring the friction between the positioning shaft and the cable body; the problem of the existing cable sliding off due to slipping during transportation is solved.

[0017] Secondly, the present invention rotates the adjusting screw to rotate the positioning rod around the rotating shaft. Therefore, the positions of the two positioning rotating shafts are located at the upper and lower ends, thereby increasing the deformation degree of the cable body. The two positioning shafts move toward the adjacent side under the extrusion of the cable body, thereby further increasing the deformation degree of the cable body, making the cable body fit more closely with the positioning rotating shaft and the positioning shaft, thereby ensuring the conveying and traction of the cable body by the device. The elasticity of the reset spring can be released by rotating the adjusting screw to push the positioning rod to return to its original position.

[0018] Thirdly, the present invention arranges a clamping plate on a side wall where two clamping plates are close to each other. Since the lower guide frame and the upper guide frame are in an arc shape with the rotating shaft as the center, and the side walls where the two lower guide frames and the two upper guide frames are close to each other are in an arc shape, when the inclination angle of the positioning rod is larger, the distance between the two positioning blocks on the side wall of the positioning shaft under the guidance of the lower guide frame and the upper guide frame is closer, the degree of deformation of the cable body is increased, and under the pulling of the cable body, the distance between the two positioning shafts is closer, and the distance between the clamping blocks under the guidance of the clamping plate is closer, so that the device can transport cables with different radii.

[0019] Fourthly, the present invention rotates the storage rotating rod to rewind the two pull ropes around the side wall of the storage rotating rod, so that the two pull ropes will pull the two limit grooves to move toward the adjacent side, thereby reducing the distance between the lower fixed plate and the upper fixed plate, so that the lower fixed plate and the upper fixed plate can move together with the positioning frame to ensure support for the lower guide frame and the upper guide frame.

[0020] Fifth: In the present invention, when the lower fixed plate approaches the storage rotating rod, the lower movable plate will contact the lifting plate, and the lifting plate will push the lower movable plate to rotate around the adjusting shaft, so that the lower movable plate pushes the lower guide frame to rotate and adjust the inclination angle of the lower guide frame; when the upper fixed plate approaches the storage rotating rod, the linkage rotating bar will pull the upper rotating plate to rotate around the connection between the upper rotating plate and the positioning bar, pushing the top end of the upper guide frame to tilt inward, so that when the positioning rotating shaft moves inside the lower guide frame and the upper guide frame, the lower guide frame and the upper guide frame can push the positioning block to move.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides a power cable transmission and traction device through improvement. The technical solution of the present invention is: like Figure 1-Figure 5As shown, a power cable transmission and traction device comprises a base 1, a cable body 4 is arranged on the top of the base 1, a traction assembly is arranged on the top of the base 1, the traction assembly comprises two clamping plates 21, the two clamping plates 21 are fixedly mounted on the top wall of the base 1, two sliding grooves 24 are arranged on the side walls of the two clamping plates 21, a positioning shaft 25 is slidably mounted inside the sliding grooves 24 on one side of the two clamping plates 21, a driving motor 22 is fixedly mounted on the side wall of the clamping plate 21, a worm 23 is fixedly mounted on the output shaft of the driving motor 22, a worm wheel 26 is fixedly mounted on the end of the positioning shaft 25 close to the worm 23, the worm wheel 26 and the worm 23 are meshed with each other, a limiting block 29 is fixedly mounted on the end of the positioning shaft 25 away from the worm 23, a guide assembly is arranged on the top of the base 1, the guide assembly comprises two mounting brackets 37, the two mounting brackets 37 are respectively fixedly mounted on the top walls of the two clamping plates 21, and a positioning rod 31 is arranged between the two mounting brackets 37. , a rotating shaft 38 that rotates and penetrates the side wall of the positioning rod 31 is fixedly installed on the side walls of the two mounting frames 37, and a positioning frame 32 is arranged at both ends of the bottom of the positioning rod 31, and the positioning frame 32 is in a "Y" shape. The bottom ends of the inner side walls of the two positioning frames 32 are rotatably installed with a positioning shaft 34; by inserting the cable body 4 into the interior of the two positioning frames 32 and between the two clamping plates 21 in an "S" shape, the side wall of the cable body 4 is fitted with the positioning shaft 34 and the side wall of the positioning shaft 25, and the worm 23 is driven to rotate by the output end of the driving motor 22, and the worm wheel 26 and the worm 23 are meshed with each other, so the worm wheel 26 will drive the positioning shaft 25 to rotate together, and the rotation of the positioning shaft 25 drives the cable body 4 to move, thereby achieving the effect of conveying and traction of the cable body 4, and because the cable body 4 is distributed in an "S" shape, when the cable body 4 is pulled, the cable body 4 can fit more closely with the side wall of the positioning shaft 25, thereby ensuring the friction between the positioning shaft 25 and the cable body 4.

[0025] like Figure 1-Figure 5As shown, in order to make the cable body 4 fit more closely with the side walls of the positioning shaft 25 and the positioning rotating shaft 34, an adjustment component is provided on the top of the base 1, and the adjustment component includes a mounting block 64 fixedly installed between the two mounting frames 37, an adjusting screw 65 is threadedly installed on the side wall of the mounting block 64, and a lower rotating block 66 is fixedly installed on one end of the adjusting screw 65, and an upper rotating block 67 is fixedly installed on the bottom wall of the positioning rod 31, and a linkage pull plate 68 is rotatably installed on the adjacent ends of the upper rotating block 67 and the lower rotating block 66, and a reset spring 69 is fixedly connected to the position of the bottom wall of the positioning rod 31 away from the upper rotating block 67, and the bottom end of the reset spring 69 is fixedly connected to the top wall of the mounting block 64; by rotating the adjustment The screw 65 causes the positioning rod 31 to rotate around the rotating shaft 38, so that the positions of the two positioning shafts 34 are at the upper and lower ends, thereby increasing the degree of deformation of the cable body 4. The two positioning shafts 25 move toward the adjacent side under the extrusion of the cable body 4, further increasing the degree of deformation of the cable body 4, making the cable body 4 fit more closely with the positioning shafts 34 and the positioning shafts 25, thereby ensuring the conveying and traction of the cable body 4 by the device. By adjusting the rotation of the screw 65, the elasticity of the reset spring 69 can be released, pushing the positioning rod 31 to return to its original position; the two ends of the two positioning shafts 25 are slidably installed with clamping blocks 27 distributed in a mirror image, and the two ends of the positioning shaft 34 are rotatably installed with positioning blocks 33 distributed in a mirror image, and the clamping blocks 27 and the positioning shafts 34 are rotatably installed. The positioning blocks 33 are all in the shape of a truncated cone; the contact area between the positioning shaft 25 and the positioning shaft 34 and the cable body 4 is increased by the clamping block 27 and the positioning block 33, the friction between the device and the cable body 4 is increased, and the transportation and traction of the cable body 4 is facilitated; a clamping plate 28 is fixedly installed on the side wall surface close to the two clamping plates 21, and the clamping plate 28 is in a triangular shape. The side wall of the clamping block 27 fits with the side wall close to the clamping plate 28. Two lower guide frames 35 are sleeved on the side wall of the positioning shaft 34 close to the upper rotating block 67, and two upper guide frames 36 are sleeved on the side wall of the positioning shaft 34 away from the upper rotating block 67. The lower guide frame 35 and the upper guide frame 36 are both in the shape of an arc with the rotating shaft 38 as the center, and the lower guide frame 35 and the upper The side walls adjacent to the guide frames 36 are inclined; by setting a clamping plate 28 on a side wall adjacent to the two clamping plates 21, since the lower guide frame 35 and the upper guide frame 36 are in an arc shape with the rotating shaft 38 as the center, and the side walls adjacent to the two lower guide frames 35 and the two upper guide frames 36 are in an arc shape, when the inclination angle of the positioning rod 31 is larger, the distance between the two positioning blocks 33 on the side wall of the positioning shaft 34 is closer under the guidance of the lower guide frame 35 and the upper guide frame 36, the greater the degree of deformation of the cable body 4 is increased, and under the pulling of the cable body 4, the distance between the two positioning shafts 25 is closer, and the distance between the clamping blocks 27 under the guidance of the clamping plate 28 is closer, so that the device can transport cables of different radii.

[0026] like Figure 1-Figure 5As shown, in order to ensure the stable position of the lower guide frame 35 and the upper guide frame 36, a fixing component is provided on the top of the base 1, and the fixing component includes two lower fixing plates 51, and the top ends of the two lower fixing plates 51 are rotatably mounted on the top ends of the two lower guide frames 35 through hinges. Two upper fixing plates 55 are provided on the top of the base 1, and the top ends of the two upper fixing plates 55 are rotatably mounted on the bottom ends of the two upper guide frames 36 through hinges; the lower guide frame 35 and the upper guide frame 36 are fixed respectively by the lower fixing plate 51 and the upper fixing plate 55 to ensure the stable position of the lower guide frame 35 and the upper guide frame 36; two adjusting grooves 61 are provided on the bottom wall of the positioning rod 31, and the top ends of the two positioning frames 32 are slidably mounted inside the two adjusting grooves 61 respectively, and the two ends of the positioning rod 31 are rotatably mounted with moving screws 63 extending into the inside of the adjusting grooves 61, and the two positioning frames 32 are threadedly mounted on the side walls of the two moving screws 63 respectively; The two movable screws 63 are rotated to adjust the distance between the two positioning frames 32, so that the positioning rod 31 rotates a smaller distance, which can increase the deformation of the cable body 4 and make the cable with a smaller radius easier to deform; a lower movable plate 52 is provided at one end of the two lower fixed plates 51 close to the clamping plate 21, and an adjusting shaft 53 is rotatably passed through the side wall where the lower movable plate 52 and the lower fixed plate 51 are in contact, and the top of the lower movable plate 52 is in contact with the bottom end of the lower guide frame 35, and a positioning bar 56 is fixedly installed on the top wall of the base 1, and two upper rotating plates 57 are rotatably installed on the side wall of the positioning bar 56, and connecting rotating blocks 58 are fixedly installed on the side walls of the two upper guide frames 36, and the top ends of the two upper rotating plates 57 are rotatably installed on the side walls of the two connecting rotating blocks 58; the lower guide frame 35 and the upper guide frame 36 are supported by the two lower movable plates 52 and the two upper rotating plates 57 respectively, so as to further ensure the stability of the position of the lower guide frame 35 and the upper guide frame 36.

[0027] like Figure 1-Figure 5As shown, when the distance between the two positioning frames 32 becomes smaller, the angles of the lower guide frame 35 and the upper guide frame 36 can change synchronously. A moving assembly is provided on the top of the base 1, and the moving assembly includes two limit grooves 71 opened on the top wall of the base 1. The interiors of the two limit grooves 71 are slidably installed with mounting rods 72. The side walls of the two mounting rods 72 are respectively fixedly connected to the two lower fixing plates 51 and the upper fixing plate 55 of the camera. A storage rotating rod 74 is rotatably installed on the side wall of the clamping plate 21, and a ratchet mechanism is provided on the side wall where the storage rotating rod 74 and the clamping plate 21 are in contact; the ratchet mechanism is a prior art and will not be described in detail here. The ratchet mechanism is used to ensure the stability of the position of the storage rotating rod 74; two pull ropes 73 are wound around the side wall of the storage rotating rod 74, and the two pull ropes are wound around the side wall of the storage rotating rod 74. The ends of the ropes 73 away from the storage rotating rod 74 are respectively fixedly connected to the side walls of the two mounting rods 72; by rotating the storage rotating rod 74, the two pull ropes 73 are rewound around the side walls of the storage rotating rod 74, and the two pull ropes 73 will pull the two limit slots 71 to move toward the adjacent side, so that the distance between the lower fixed plate 51 and the upper fixed plate 55 becomes smaller, so that the lower fixed plate 51 and the upper fixed plate 55 can move together with the positioning frame 32 to ensure support for the lower guide frame 35 and the upper guide frame 36; the side walls of the two mounting rods 72 that are adjacent are fixedly connected with extrusion springs 75; by utilizing the elasticity of the extrusion springs 75, when the storage rotating rod 74 rotates, the extrusion springs 75 can push the limit slots 71 to move toward the side away from the storage rotating rod 74.

[0028] like Figure 1-Figure 5As shown, two lifting plates 54 are fixedly installed on the top wall of the base 1, and the side walls of the lifting plates 54 are inclined. The two lifting plates 54 are aligned with the two lower movable plates 52 respectively, and the side walls of the two upper fixed plates 55 are rotatably installed with linkage rotation strips 59, and one end of the linkage rotation strip 59 away from the upper fixed plate 55 is rotatably installed on the top position of the side wall of the adjacent upper rotating plate 57; when the lower fixed plate 51 approaches the storage rotating rod 74, the lower movable plate 52 will contact the lifting plate 54, and the lifting plate 54 will push the lower movable plate 52 to rotate around the adjustment shaft 53, so that the lower movable plate 52 pushes the lower guide frame 35 to rotate, and the inclination angle of the lower guide frame 35 is adjusted. When the upper fixed plate 55 approaches the storage rotating rod 74, the linkage rotation strip 59 will pull the upper rotating plate 57 to rotate around the connection between the upper rotating plate 57 and the positioning strip 56, and push the top of the upper guide frame 36 to tilt inward. The upper and lower guide frames 35 and 36 are connected to each other by the upper and lower rotating plates 57, so that when the upper and lower guide frames 35 move, the inclination angle of the upper and lower rotating plates 57 changes less, which is convenient for the upper guide frame 36 to move. When the positioning rod 31 rotates around the rotating shaft 38, the positioning shaft 34 can still move inside the lower guide frame 35 and the upper guide frame 36. Since the lower guide frame 35 and the upper guide frame 36 are in an arc shape and only one end of the lower guide frame 35 and the upper guide frame 36 is fixed, when the positioning shaft 34 moves along the inside of the lower guide frame 35 and the upper guide frame 36, the shape of the lower guide frame 35 and the upper guide frame 36 can change with the movement of the positioning shaft 34, so that when the positioning shaft 34 moves inside the lower guide frame 35 and the upper guide frame 36, the lower guide frame 35 and the upper guide frame 36 can push the positioning block 33 to move.

[0029] The specific working method is: by inserting the cable body 4 into the interior of the two positioning frames 32 and between the two clamping plates 21 in an "S" shape, the side wall of the cable body 4 is fitted with the side wall of the positioning shaft 34 and the positioning shaft 25, and then rotating the adjusting screw 65, so that the adjusting screw 65 pulls the bottom end of the linkage pull plate 68 to move toward the mounting block 64, and the top end of the linkage pull plate 68 therefore pulls the upper rotating block 67 downward, and the positioning rod 31 therefore rotates around the rotating shaft 38, and the two positioning frames 32 also rotate synchronously with the positioning rod 31, and the positioning shaft 34 inside the positioning frame 32 squeezes the cable body 4 to increase the deformation degree of the cable body 4, and at the same time, in the process of pulling the cable body 4, the side wall of the cable body 4 is tightly fitted with the side wall of the positioning shaft 34 and the positioning shaft 25. The clamping plate 28 is fixedly mounted on the side wall of the clamping plate 21, and the side walls of the two positioning shafts 34 are respectively sleeved with a lower guide frame 35 and an upper guide frame 36, and the lower guide frame 35 and the upper guide frame 36 are both in an arc shape with the rotating shaft 38 as the center, and the side walls of the lower guide frame 35 and the upper guide frame 36 are inclined. Therefore, when the positioning rod 31 rotates, the two positioning shafts 34 slide along the inside of the lower guide frame 35 and the upper guide frame 36 respectively, and the side walls of the lower guide frame 35 and the upper guide frame 36 push the side walls of the positioning blocks 33, so that the two positioning blocks 33 on the side walls of the positioning shaft 34 move to the adjacent side. The cable body 4 will push the two positioning shafts 25 to move to the adjacent side during the deformation process, and the clamping plate 28 is provided with a clamping plate 28 on the side wall of the clamping plate 21. The side wall of the tightening plate 28 will push the clamping block 27 to move, so that the two clamping blocks 27 on the side wall of the positioning shaft 25 move close to each other. The positioning block 33 and the side wall of the clamping block 27 are therefore fitted with the side wall of the cable body 4, thereby increasing the contact area between the device and the cable body 4 and further increasing the traction force of the device. When the cable body 4 is thinner, in order to increase the degree of deformation of the cable body 4, the two moving screws 63 can be rotated to adjust the distance between the two positioning frames 32, so that the positioning rod 31 can be rotated a smaller distance to increase the deformation of the cable body 4, and then the storage rotating rod 74 is rotated to make the two pull ropes 73 rewound around the side wall of the storage rotating rod 74. The two pull ropes 73 will therefore pull the two limit grooves 71 to move to the adjacent side, and the lower fixed plate 51 and the upper fixed plate The distance between the fixed plates 55 is thus reduced, so that the lower fixed plate 51 and the upper fixed plate 55 can move together with the positioning frame 32, and the lower movable plate 52 will contact the lifting plate 54 to adjust the inclination angle of the lower guide frame 35. When the upper fixed plate 55 approaches the storage rotating rod 74, the linkage rotating bar 59 will pull the upper rotating plate 57 to rotate around the connection between the upper rotating plate 57 and the positioning bar 56, pushing the top end of the upper guide frame 36 to tilt inward. Since the lower guide frame 35 and the upper guide frame 36 are in an arc shape and only one end of the lower guide frame 35 and the upper guide frame 36 is fixed, when the positioning rotating shaft 34 moves along the inside of the lower guide frame 35 and the upper guide frame 36, the shape of the lower guide frame 35 and the upper guide frame 36 can change with the movement of the positioning rotating shaft 34.When the positioning shaft 34 moves inside the lower guide frame 35 and the upper guide frame 36, the lower guide frame 35 and the upper guide frame 36 can push the positioning block 33 to move.
