Description

Technical Field

[0001] The present invention relates to the technical field of cable pulling, and in particular to a cable pulling machine used for laying cables. Background Art

[0002] Cable conveyors and cable traction machines are both electric machines for laying power cables. Through the use of multiple machines, construction is convenient and fast, which can greatly save manpower and material resources, thereby effectively reducing construction costs. With the continuous development and improvement of social living standards, the scale of urban power grids is also expanding. The traditional manual cable laying method can no longer meet the requirements. In order to reduce the labor intensity of cable laying and ensure construction quality;

[0003] At present, a variety of conveying devices for pulling and conveying cables have been developed in China, but the existing cable conveying will cause a certain degree of damage to the cable at the bends, and the working stability is poor. Most cable conveyors on the market are manually cranked, with low working efficiency, which seriously affects the construction progress and quality. In addition, the cable is usually wound on the reel, which will curl before pulling and easily swing during pulling, affecting the transportation of the cable. Therefore, we proposed a cable pulling machine for cable laying. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a cable pulling machine for cable laying, comprising:

[0005] A base, wherein a universal wheel is provided at the bottom of the base and the universal wheel is driven by a motor;

[0006] A traction mechanism having a positioning structure and used for traction during cable laying;

[0007] The bottom of the base is symmetrically arranged with the top of the universal wheel, and the universal wheel is symmetrically arranged at the bottom of the base, and the side of the traction mechanism close to the universal wheel is fixedly connected to the top of the base;

[0008] Wherein, the traction mechanism includes:

[0009] Conveyor belt, the outer side of the conveyor belt has grooves to assist in the routing of cables;

[0010] a transmission assembly for driving the conveyor belt, and a cover plate disposed on top of the transmission assembly;

[0011] A shaking component having a buffer structure for reducing shaking when the cable is routed;

[0012] A bending assembly having an extrusion structure for assisting the cable in bending when pulling and turning;

[0013] The inner side surface of the conveyor belt is rotatably connected to the outer side of the transmission assembly, and the side of the transmission assembly close to the universal wheel is fixedly connected to the top of the base, and the inner side surface of the cover plate is rotatably connected to the surface of the transmission assembly away from the base. The shaking assembly and the bending assembly are symmetrically arranged on both sides of the base, and the shaking assembly is fixedly connected to the top of the base, and the bottom of the bending assembly is fixedly connected to the top of the base away from the shaking assembly. The cable passes through the shaking assembly and then enters the gap between the base and the cover plate. The outer side surface of the conveyor belt contacts the cable surface, and the conveyor belt fixes the cable line and then passes through the bending assembly. The universal wheel is driven to rotate by the motor, driving the base to move, and finally driving the cable line to move, completing the traction of the cable line, starting the transmission assembly, and the transmission assembly drives the conveyor belt transmission, driving the cable and the base to produce relative movement, which can be in a fixed position The cable is transported, pulled and tightened, and a groove is provided on the outer side of the conveyor belt, which can increase the friction between the conveyor belt and the cable, and can pull cables with heavier mass to avoid slipping between the cable and the conveyor belt. When the cable is laid at a bend, the traction machine is arranged at the bend position, the universal wheel drive base is tangent to the bend path, the cable line contacts the extrusion structure of the bending component, and the cable line is squeezed to cause the cable to bend. The setting of the bending component can increase the turning radius of the cable, reduce the bending angle of the cable line, avoid the cable core bending angle being too large, and avoid damage to the cable core. When the cable line is pulled, the cable line may curl up, and the cable line entry position may swing during transportation. A shaking component is provided, and its buffer structure can buffer the swing of the cable line to avoid the cable line swing affecting traction.

[0014] Furthermore, the conveyor belts are symmetrically arranged at the interval between the base and the cover plate, and grooves are evenly provided on the outer sides of the two conveyor belts. The two conveyor belts are both concave inwardly in the shape of an arc surface. The two symmetrical conveyor belts can clamp the cable inserted between the two conveyor belts. Under the transportation of the two conveyor belts, the cable can be driven to move, and the cable is tightened at a fixed position. The conveyor belts are concave inwardly in the shape of an arc surface, which can adapt to the cylindrical surface of the cable, thereby better clamping the cable and obtaining a better transportation effect.

[0015] Furthermore, the transmission assembly includes conveying rollers, which are symmetrically arranged at both ends of the conveyor belt. The surfaces of the conveying rollers are concave inward, and the surfaces of the conveying rollers are transmission-connected to the inner side surfaces of the conveyor belt. The conveying rollers are driven to rotate, driving the conveyor belts to be transmitted, so that the two conveyor belts are transported toward the side close to the bending assembly. The surfaces of the conveying rollers are concave inward, and the inner side surfaces of the conveyor belts transmission-connected thereto protrude inward, which can prevent the conveyor belts from shaking up and down during transmission, thereby ensuring stability when conveying cables.

[0016] Furthermore, a placement groove is provided on the side of the base close to the conveying roller, and the placement groove is symmetrically arranged on the top of the base, and a rotating shaft is provided inside the conveying roller, and one end of the rotating shaft close to the conveyor belt passes through the conveying roller and the cover plate, and the surface of the rotating shaft is fixedly connected to the inner side surface of the conveying roller, and the surface of the rotating shaft is rotatably connected to the inner side surface of the cover plate, and a motor is symmetrically provided inside the placement groove near the bending component, and the surface of the motor is fixedly connected to the bottom of the inner wall of the placement groove, and the output end of the motor is fixedly connected to the end of the rotating shaft located inside the placement groove, and the end of the rotating shaft away from the motor located on the inner wall of the placement groove is rotatably connected to the bottom of the inner wall of the placement groove, and the motor is started, and the output end of the motor drives the rotating shaft to rotate, drives the conveying roller to rotate, drives the conveyor belt to transmit, and drives the other conveying roller to rotate, thereby realizing stable transmission of the conveyor belt.

[0017] Furthermore, a conveyor belt is provided directly above the two motors, and the two conveyor belts are respectively arranged on the side of the two conveyor belts away from the base, and the inner side surface of the conveyor belt is connected to the surface of the rotating shaft. The rotating shaft rotates to drive the conveyor belt, thereby driving the other rotating shaft on the same side to rotate. The two rotating shafts rotate at the same time, which can drive the conveyor belt to transmit stably and avoid deformation due to friction resistance when the conveyor belt is tightened by the cable, thereby ensuring the tightening effect. A stabilizing plate is provided on the inner wall of the placement groove, and the surface of the stabilizing plate is fixedly connected to the inner wall of the placement groove. The end of the rotating shaft close to the conveyor belt passes through the stabilizing plate, and the inner side surface of the stabilizing plate is rotatably connected to the surface of the rotating shaft. The stabilizing plate is provided to limit the two rotating shafts located inside the placement groove to avoid vibration and noise when the rotating shaft rotates, while maintaining the stability of the conveyor belt during transportation.

[0018] Furthermore, the shaking assembly includes a rod body, two of which are provided on the side of the conveyor belt away from the bending assembly, both ends of the rod body away from the conveyor belt are fixedly connected to a fixing seat, the surface of the fixing seat is fixedly connected to the top of the base, and both ends of the rod body close to the conveyor belt are fixedly connected to a distance adjusting assembly, the surface of the distance adjusting assembly is fixedly connected to the top of the base, the surfaces of the two rod bodies are slidably connected to a sliding sleeve, the surfaces of the sliding sleeves are rotatably connected to a shaking roller, the middle surface of the shaking roller is concave inward, and the surface of the shaking roller is circumferentially distributed with anti-slip rubber strips, and the distance adjusting assembly is started, and the distance adjusting assembly drives the rod body close to the conveyor belt to rise, thereby driving the sliding sleeve and shaking roller outside it to rise, and passing the cable through the gap between the two shaking rollers. When the distance adjustment component is started, the rod body, sliding sleeve, and shaking roller are driven to descend so that both shaking rollers can contact the cable. When the cable is pulled, the cable is straightened under the action of the two conveyor belts, and the curled parts are also stretched. At this time, the cable between the two shaking rollers rotates and shakes, driving the shaking roller to rotate and slide along the surface of the rod body, avoiding excessive swinging of the cable inserted between the two conveyor belts, and even accumulation and entanglement of the curled parts, so as to avoid affecting the traction effect. The anti-slip rubber strip on the surface of the shaking roller can increase the friction between the cable and prevent the cable from escaping from the depression between the two shaking rollers, thereby ensuring a stable stretching effect, and the limit position of the shaking roller depression can ensure that the cable drives the shaking roller to slide on the surface of the rod body, thereby ensuring the straightening and stretching of the cable.

[0019] Furthermore, both ends of the sliding sleeve are fixedly connected to a spring, and the two springs are respectively sleeved on the outside of the two rod bodies. The radius of the spring gradually increases toward the side away from the rod body. The ends of the two springs located at the two fixing seats that are away from each other are respectively fixedly connected to the sides of the two fixing seats that are close to each other. The ends of the two springs located at the two adjustable distance assemblies that are away from each other are respectively fixedly connected to the sides of the two adjustable distance assemblies that are close to each other. The shaking roller slides on the surface of the rod body, driving the two springs to stretch or compress, thereby buffering the movement of the shaking roller, avoiding collision of the shaking roller, and avoiding noise. At the same time, under the action of deformation resistance, the swing speed of the cable is reduced, avoiding excessive swing amplitude, and avoiding damage to the wire core inside the cable. The radius of the spring gradually increases toward the side away from the sliding sleeve, so that when the cable swings at the beginning, the deformation resistance of the spring away from the sliding sleeve is small, and the spring can deform quickly, providing a more sensitive buffering effect. During subsequent deformation, the resistance increases, limiting the swing amplitude of the cable, and avoiding damage to the wire core. The gradually increasing radius can provide uniform buffering deceleration, avoiding sudden deceleration of the cable, and can slowly bend when stretching the cable, avoiding damage to the wire core.

[0020] Furthermore, the distance adjusting assembly includes a distance adjusting seat, which is symmetrically arranged at both ends of the rod body near the conveyor belt, and the surface of the distance adjusting seat is fixedly connected to the top of the base, and a slide is provided inside the two distance adjusting seats, and the surface of the slide slide is limited to slide with the inner side surface of the distance adjusting seat, and the two sides of the slide slides close to each other are fixedly connected to the two ends of the rod body located at the interval between the two distance adjusting seats, and the side of the slide slide close to the base is fixedly connected to a telescopic rod, and the end of the telescopic rod away from the slide slide is fixedly connected to the bottom of the inner wall of the distance adjusting seat, and the telescopic rod is started and extended, driving the slide to rise and fall, thereby driving the rod body fixed thereto to rise and fall, and finally adjusting the spacing between the two rocking rollers to limit cables of different sizes to the middle of the conveyor belt, ensuring the positioning of different cables, and straightening and stretching of different cables.

[0021] Furthermore, the bending assembly includes a cylinder, the surface of the cylinder is fixedly connected to the top of the base, and connecting seats are symmetrically provided on both sides of the cylinder, and the connecting seats are fixedly connected to the top of the base, and the sides of the two connecting seats close to each other are fixedly connected to the surface of the cylinder, and a bending plate is provided inside the cylinder, and the two ends of the bending plate are fixedly connected to the inner side surface of the cylinder, and several bending plates are provided along the circumference of the cylinder. The cable passes through the cylinder, and the bending plate contacts the surface of the cable, and the bending plate is deformed to adapt to cables of different diameters and limit cables of different diameters. When the cable needs to bend, the bending plate rests on the bending position of the cable to assist the cable in bending, increase the bending radius of the cable, reduce the bending angle of the cable, and avoid damage to the cable core due to excessive bending angle.

[0022] Furthermore, a support block is fixedly connected to one side of the bending plate close to the inner wall of the cylinder, and a side of the support block away from the bending plate is fixedly connected to the inner side surface of the cylinder, and the support block is arranged at the position of the bending plate farthest from the cylinder. An elliptical hole is opened through the surface of the support block. The elliptical hole is provided so that the support block can be deformed to cooperate with the positioning of the bending plate on the cable, and the support of the support block can increase the abutment effect of the bending plate on the cable, better increase the bending radius of the cable, and avoid damage to the cable core due to excessive bending.

[0023] The present invention has the beneficial effects:

The present invention provides a traction mechanism, which drives the universal wheel to rotate through the motor to complete the traction of the cable, and the transmission component drives the conveyor belt to drive, which drives the cable and the base to move relative to each other, and can transport the cable in a fixed position, pull and tighten the cable. The outer side of the conveyor belt is provided with a groove, which can increase the friction between the conveyor belt and the cable, and can pull cables with larger mass to avoid slipping between the cable and the conveyor belt. The conveyor belt is concave inwardly in an arc shape, which can adapt to the surface of the cylindrical cable, so as to better clamp the cable and obtain a better conveying effect. The surface of the conveying roller is concave inwardly, and the inner side of the conveyor belt connected to it for transmission protrudes inwardly, which can avoid the conveyor belt from shaking up and down during transmission, thereby ensuring stability when conveying cables.

[0025] 2. The present invention sets a shaking component. When the cable is pulled, the cable is straightened and the curled parts are stretched under the action of the two conveyor belts. At this time, the cable located between the two shaking rollers rotates and shakes, driving the shaking roller to rotate and slide along the surface of the rod body, thereby preventing the cable inserted between the two conveyor belts from swinging excessively, and even accumulating and entangled in the curled parts, thereby avoiding affecting the traction effect. The anti-slip rubber strip on the surface of the shaking roller can increase the friction between the cable and prevent the cable from escaping from the depression between the two shaking rollers, thereby ensuring a stable stretching effect. The limiting position of the depressed position of the shaking roller can ensure that the cable drives the shaking roller to slide on the surface of the rod body, thereby ensuring the straightening and stretching of the cable.

[0026] 3. The present invention provides a spring, and the rocking roller slides on the surface of the rod body, driving the two springs to stretch or compress, thereby buffering the movement of the rocking roller, avoiding collision of the rocking roller, and avoiding noise. At the same time, under the action of deformation resistance, the swing speed of the cable is reduced, avoiding excessive swing amplitude and damage to the wire core inside the cable, and the radius of the spring gradually increases toward the side away from the sleeve, so that when the cable initially swings, the deformation resistance of the spring away from the sleeve is small, and the spring can deform quickly, providing a more sensitive buffering effect. During subsequent deformation, the resistance increases, limiting the swing amplitude of the cable, avoiding damage to the wire core, and the gradually increasing radius can provide uniform buffering deceleration, avoiding sudden deceleration of the cable, and can slowly bend when stretching the cable to avoid damage to the wire core.

[0027] 4. The present invention sets a distance-adjusting component, and the bending plate adapts to the deformation of cables of different diameters and limits the cables of different diameters. When the cable needs to bend, the bending plate rests on the bending position of the cable to assist the cable in bending, thereby increasing the bending radius of the cable and reducing the bending angle of the cable, thereby avoiding damage to the cable core due to excessive bending angle. The elliptical hole enables the support block to deform, cooperates with the positioning of the bending plate on the cable, and the support of the support block can increase the abutment effect of the bending plate on the cable, better increase the bending radius of the cable, and avoid damage to the cable core due to excessive bending.

Start the motor 324, and the output end of the motor 324 drives the rotating shaft 323 to rotate, drives the conveying roller 321 to rotate, drives the conveyor belt 31 to transmit, and drives the other conveying roller 321 to rotate, thereby realizing stable transmission of the conveyor belt 31.

[0051] The two conveyor belts 325 are respectively arranged above the two motors 324. The two conveyor belts 325 are respectively arranged on the side of the two conveyor belts 31 away from the base 1, and the inner side surface of the conveyor belt 325 is transmission-connected to the surface of the rotating shaft 323.

The two rotating shafts 323 rotate at the same time, which can drive the conveyor belt 31 to transmit stably, and avoid deformation due to friction resistance when the conveyor belt 31 is tightened by the cable, thereby ensuring the tightening effect. The inner wall of the placement groove 322 is provided with a stabilizing plate 326, the surface of the stabilizing plate 326 is fixedly connected to the inner wall of the placement groove 322, and the end of the rotating shaft 323 close to the conveyor belt 31 passes through the stabilizing plate 326, and the inner side surface of the stabilizing plate 326 is rotationally connected to the surface of the rotating shaft 323.

The cam 343 is pressed against the top of the gear 344 and the bottom of the gear 345 is pressed against the gear 346, so that the cam 343 is pressed against the gear 347.

[0053] Both ends of the sliding sleeve 342 are fixedly connected with springs 346. The two springs 346 are respectively sleeved on the outside of the two rod bodies 341. The radius of the spring 346 gradually increases towards the side away from the rod body 341. The ends of the two springs 346 located at the two fixing seats 344 that are away from each other are respectively fixedly connected to the sides of the two fixing seats 344 that are close to each other. The ends of the two springs 346 located at the two distance adjustment components 345 that are away from each other are respectively fixedly connected to the sides of the two distance adjustment components 345 that are close to each other. The rocking roller 343 slides on the surface of the rod body 341, driving the two springs 346 to stretch or compress, thereby buffering the movement of the rocking roller 343 to prevent rocking The roller 343 produces an impact to avoid noise. At the same time, under the action of deformation resistance, the swing speed of the cable is reduced to avoid excessive swing amplitude and damage to the wire core inside the cable.

During subsequent deformation, the resistance increases to limit the swing amplitude of the cable and avoid damage to the wire core.

[0056] The side of the bent plate 353 close to the inner wall of the cylinder 351 is fixedly connected to a support block 354, and the side of the support block 354 away from the bent plate 353 is fixedly connected to the inner side surface of the cylinder 351, and the support block 354 is arranged at the position of the bent plate 353 farthest from the cylinder 351. An elliptical hole 355 is opened through the surface of the support block 354. The elliptical hole 355 is provided so that the support block 354 can be deformed to cooperate with the positioning of the bent plate 353 on the cable. The support of the support block 354 can increase the abutment effect of the bent plate 353 on the cable, better increase the bending radius of the cable, and avoid damage to the cable core due to excessive bending.

[0057] When in use, the cable passes through the shaking component 34 and then enters the gap between the base 1 and the cover plate 33. The two symmetrical conveyor belts 31 can clamp the cable passed through the two conveyor belts 31, and the universal wheel 2 is driven by the motor to rotate, driving the base 1 to move, and finally driving the cable to move, completing the traction of the cable, starting the motor 324, and the output end of the motor 324 drives the rotating shaft 323 to rotate, driving the conveying roller 321 to rotate, driving the conveyor belt 31 to transmit, driving the other conveying roller 321 to rotate, and at the same time, the rotating shaft 323 rotates, driving the conveyor belt 325 to transmit, thereby driving the other rotating shaft 323 on the same side to rotate, thereby achieving stable transmission of the conveyor belt 31, under the transportation of the two conveyor belts 31, it can drive the cable to move, drive the cable and the base 1 to move relative to each other, transport the cable in a fixed position, pull the cable and tighten it, start the telescopic rod 3453, the telescopic rod 3453 is extended and retracted, driving the slide plate 3452 to rise and fall, thereby driving the rod body 341 fixed to it to rise and fall, and finally adjusting the two shaking The distance between the rollers 343 is adjusted, and the cable passes through the gap between the two shaking rollers 343. When the distance adjustment component 345 is started, the rod body 341, the sliding sleeve 342, and the shaking roller 343 are driven to descend, so that the two shaking rollers 343 can contact the cable. Under the action of the two conveyor belts 31, the cable is straightened and the curled part is stretched. At this time, the cable between the two shaking rollers 343 rotates and shakes, driving the shaking roller 343 to rotate and slide along the surface of the rod body 341. The shaking roller 343 is on the surface of the rod body 341. Sliding drives the two springs 346 to stretch or compress, thereby buffering the movement of the rocking roller 343. The cable passes through the cylinder 351, and the bent plate 353 contacts the surface of the cable. The bent plate 353 is deformed to adapt to cables of different diameters and limit cables of different diameters. When the cable is laid at a bend, the traction machine is arranged at the bend position, the universal wheel 2 drives the base 1 to be tangent to the bend path, and the bent plate 353 rests on the bending position of the cable to assist the cable in bending and increase the bending radius of the cable.
