Description

Technical Field

[0001] The present invention relates to the technical field of cable pulling machines, and more specifically, to a combined cable pulling machine. Background Art

[0002] With the booming development of the power, communications and other industries today, the scale and complexity of cable laying projects are increasing, and traditional cable traction machines have exposed many problems in practical applications.

[0003] Low traction efficiency: Most traditional cable traction machines can only perform traction operations on a single cable. When faced with projects that require laying multiple cables at the same time, such as the integrated wiring of large commercial buildings and the laying of cables in urban underground pipe galleries, multiple repeated operations are required, which consumes a lot of time and labor costs, and the construction efficiency is extremely low.

[0004] Existing crawler-type cable tractors can pull multiple cables at the same time. However, in long-distance, large-size cable laying projects, especially submarine cable laying or power cable laying in mountainous areas, due to poor road conditions and uneven land, the crawler tracks are partially suspended or unevenly stressed, which leads to uneven distribution of traction force on multiple cables. Therefore, when multiple cables are pulled in parallel, once they are pulled by external force, it is easy for a single cable to be overstressed and break. In addition, multiple cables arranged in parallel take up a lot of space, which is not conducive to the laying and installation of cables in construction environments with limited space, such as narrow shafts and crowded cable ducts. In view of this, we propose a combined cable tractor. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0034] like Figure 1 As shown, this embodiment discloses a combined cable traction machine, including a base 1, a traction mechanism 3, a winding assembly 4 and a cleaning assembly 5.

[0035] like Figure 1 and Figure 2 As shown, an arc groove 101 is arranged on one side of the surface of the base 1, and a mounting groove 102 is arranged on the other side of the surface of the base 1.

[0036] like Figure 1-3 , Figure 7-11 As shown, the traction mechanism 3 includes a bottom plate 301, four first transmission cylinders 304, four second transmission cylinders 305, two first conveyor belts 306, and two second conveyor belts 307. The bottom plate 301 is fixedly connected to the inside of the installation groove 102 by bolts, and there is a gap between the bottom plate 301 and the bottom of the installation groove 102; a through groove 3011 distributed along its length direction is opened in the middle of the bottom plate 301, and four first waist-shaped holes 3012 are opened on the bottom plate 301 and close to the through groove 3011. The four first waist-shaped holes 3012 are arranged in a rectangular position, and at least one waist-shaped sliding groove 3013 is opened at the end of the bottom plate 301; The top of the bottom plate 301 is fixedly connected with a support plate 302. Specifically, the support plate 302 is fixed at the through groove 3011. Four second waist-shaped holes 3021 are opened on the support plate 302, and the positions of the four second waist-shaped holes 3021 correspond to the positions of the four first waist-shaped holes 3012 respectively. Two slide plates 303 are slidably connected to the two sides of the support plate 302 in a symmetrical structure, and the two slide plates 303 are slidably connected to the top of the bottom plate 301. Since the two slide plates 303 have the same structure, the embodiment takes one of the slide plates 303 as an example for description, and the structure of the other slide plate 303 refers to the structure of the slide plate 303. Specifically, two third waist-shaped holes 3031 are symmetrically opened on the inner side of the slide plate 303, and the two third waist-shaped holes 3031 correspond to the two second waist-shaped holes 3021 on the same side thereof, and sleeves 3032 are slidably connected to the two third waist-shaped holes 3031; a through hole 3033 connected to the waist-shaped slide groove 3013 is opened at the end of the slide plate 303; The lower end of the first transmission cylinder 304 passes through the second waist-shaped hole 3021, the inner hole of the sleeve 3032, and the first waist-shaped hole 3012 in sequence and extends to the bottom of the bottom plate 301; the lower end of the second transmission cylinder 305 passes through the through hole 3033 and the waist-shaped slide groove 3013 in sequence and extends to the bottom of the bottom plate 301; the two first conveyor belts 306 are respectively wound on the two first transmission cylinders 304 located on the same side to form two sets of active crawler structures; the two second conveyor belts 307 are respectively wound on the two second transmission cylinders 305 located on the same side to form two sets of driven crawler structures. It is worth noting that the first conveyor belt 306 and the second conveyor belt 307 are composed of a plurality of transmission plates, and the two adjacent transmission plates are movably connected by a connecting piece, and the contact surface of the transmission plate is composed of rubber, which can increase the friction when conveying cables.

[0037] Furthermore, in an embodiment of the present invention, notches 308 are respectively provided on opposite sides of the two slides 303, and a telescopic rod 309 is hinged on the inner wall of each notch 308. An adjustment handle 310 is fixedly connected to the opposite ends of the two telescopic rods 309. The adjustment handle 310 of this embodiment is a "T"-shaped rod structure, and the vertical rod of the adjustment handle 310 passes through the through groove 3011 and the center hole of the support plate 302 in sequence and extends into the first cable channel. It is worth noting that the two ends of the telescopic rod 309 are diagonally distributed at the hinges with the inner wall of the notch 308. By rotating the adjustment handle 310, due to the guiding and limiting effect of the slide 303, the telescopic rod 309 is contracted, and then the two slides 303 are gathered to the middle, thereby achieving the adjustment effect of the slide 303.

[0038] In an embodiment of the present invention, Figure 6 and Figure 8As shown, the driving unit 6 includes two first motors 601, and the two first motors 601 are transmission-connected with two of the first plug rods, and the bottoms of the other two first plug rods are respectively fixedly connected with first transmission wheels 602, and the bottoms of the two second plug rods are respectively fixedly connected with second transmission wheels 603. It is worth noting that the two first motors 601 are diagonally distributed, and the first transmission cylinder 304 is driven by the first motor 601, and the second transmission cylinder 305 is driven to rotate through the first conveyor belt 306, so that the adjacent conveyor belts rotate, and the rotation directions are opposite. When the three cables are pulled, the middle cable is not affected by the conveyor belt, and a pulling force is applied to the middle cable through the other two cables, thereby achieving the pulling effect of the three cables, and the surface of the middle cable is coated with lubricating oil. During use, the friction of the middle cable is reduced, and When the cables are spirally wound, the friction between the cables can be avoided by lubricating oil, which may cause the surface of the cables to break and the spiral winding to become chaotic. The bottom of the base plate 301 is in a circular array and is movably connected to two transmission groups 604 through a fourth plug rod. It is worth noting that the transmission group 604 is composed of two pulleys, and each first transmission wheel 602 and the transmission group 604 are movably sleeved with a belt 605. It is worth noting that when the two slides 303 gather toward the middle, the second transmission wheel 603 is disconnected from the belt 605, so that the first conveyor belt 306 moves to achieve the traction effect of one cable. When the two slides 303 move to both sides, the second transmission wheel 603 is in rolling contact with the belt 605 to achieve the traction effect of multiple cables, and the second transmission wheel 603 is in rolling contact with the belt 605.

[0039] In an embodiment of the present invention, Figure 4 As shown, the winding assembly 4 includes two support frames 401, and the two support frames 401 are symmetrically fixedly connected to the inner wall at the bottom of the arc groove 101. The inner walls of the two support frames 401 are movably connected to the transmission gear 402 through the second latch, and the inner walls of the two support frames 401 are movably connected to the gear ring 403, and the gear ring 403 is meshed with the transmission gear 402. One side of one of the support frames 401 is fixedly connected to the second motor 404, and the second motor 404 is transmission-connected to one of the transmission gears 402, and the inner wall of the gear ring 403 is fixedly connected to the threading plate 405. By setting the winding assembly 4, the present invention can pull multiple cables when the plurality of cables are pulled. Two effects can be achieved by rotating the gear ring 403. One is that three cables are wound around the middle cable, and the other is that the traction direction can be adjusted according to the hole in the ground to avoid the cable surface being worn due to the cable bending and contacting the ground during traction, which affects the service life of the cable. When multiple cables are wound, the cables pass through the threading plate 405, and then the second motor 404 is operated through the external circuit mechanism. The second motor 404 drives one of the transmission gears 402 to rotate, and the gear ring 403 is rotated through the gear meshing transmission, so that the multiple cables are spirally wound around the middle cable as the axis to adapt to the narrow space.

[0040] In an embodiment of the present invention, Figure 5 and Fig.12 As shown, the cleaning assembly 5 includes two mounting frames 501, and the two mounting frames 501 are fixedly connected to the inner walls of both sides of the protective frame 2. The opposite side of the two mounting frames 501 is movably connected to a movable plate 502 through a fifth plug rod. A plurality of movable cylinders 503 are movably sleeved in the holes on the movable plate 502. The inner wall of each movable cylinder 503 is in a circular array and is movably connected to a plurality of guide wheels 504 through a sixth plug rod. It is worth noting that when the cable passes through, the guide wheel 504 is driven to rotate. Since the guide wheel 504 is inclined, the movable cylinder 503 is rotated, thereby driving the cleaning component at one end of the movable cylinder 503 to clean the surface of the cable, so as to avoid solid particles appearing on the surface of the cable when it is wound, causing the particles to be embedded in the surface of the cable, affecting In order to extend the service life of the cable, one end of each movable cylinder 503 is fixedly connected with a plurality of cleaning strips 505 in a circular array. It is worth noting that the cleaning strips 505 are composed of iron wire and sponge strips, and the sponge strips are sleeved on the surface of the iron wire, which has good stability and can prevent the cleaning strips 505 from being deformed. At the same time, the cleaning strips 505 are spiral-shaped and can effectively clean particles during the cleaning process. When cleaning the surface of the cable, the cable moves, and the guide wheel 504 contacts its surface, causing the guide wheel 504 to rotate. Since the guide wheel 504 is inclined, the kinetic energy of the cable movement is converted into torque, causing the movable cylinder 503 to rotate, driving the cleaning strips 505 to rotate, and the surface of the cable is cleaned by the spiral cleaning strips 505. Fig.12 As shown, the particles are cleaned in the opposite direction of the cable movement, which prevents the particles from contacting the cleaned cable again and affecting the service life of the cable surface.

[0041] As another embodiment of the present invention, the combined cable traction machine of the present invention also includes a protective frame 2, which is fixed on the base 1 and covers the traction mechanism 3, the winding assembly 4 and the cleaning assembly 5 together inside the protective frame 2. On the one hand, it can protect the traction mechanism 3, the winding assembly 4 and the cleaning assembly 5, and on the other hand, it can ensure the safety of the operator.

[0042] Working principle: This embodiment provides a combined cable traction machine. When in use, when a single cable is pulled, the adjusting handle 310 is rotated. Due to the guiding and limiting effect of the slide plate 303, the telescopic rod 309 is contracted, thereby causing the two slide plates 303 to gather toward the middle, and then the cable is sequentially passed through the movable cylinder 503, between the two first conveyor belts 306, and in the upper hole of the threading plate 405, and then the first motor 601 is operated through the external circuit mechanism, and the first motor 601 drives the first transmission cylinder 304 to rotate, so that the two first conveyor belts 306 rotate synchronously and in opposite directions. The cable is pulled by the first conveyor belt 306 to achieve cable installation. When multiple cables are pulled, one end of the multiple cables is first tied and fixed with a nylon tie, and the telescopic rod 309 is extended and reset by rotating the adjusting handle 310, thereby driving the two slide plates 303 to move to both sides, and then the first transmission cylinder 304 is driven to rotate by the first motor 601, and the second transmission wheel 603 is driven to rotate by the transmission group 604, such as Fig.11 As shown, the adjacent first conveyor belt 306 and the second conveyor belt 307 rotate in opposite directions to move the cables, wherein the middle cable is not affected by the first conveyor belt 306, and the middle cable is driven to move by the movement of the cables on both sides. When multiple cables are wound, the cables pass through the threading plate 405, and then the second motor 404 is driven to work through the external circuit mechanism, and the second motor 404 drives one of the transmission gears 402 to rotate, and the gear ring 403 is rotated through the gear meshing transmission, so that the multiple cables are spirally wound around the middle cable as the axis. Fig.13 As shown, it is suitable for narrow spaces. When cleaning the cable surface, the cable moves, and the guide wheel 504 contacts its surface, causing the guide wheel 504 to rotate. Since the guide wheel 504 is inclined, the kinetic energy of the cable movement is converted into torque, causing the movable cylinder 503 to rotate, driving the cleaning strip 505 to rotate, and the cable surface is cleaned by the spiral cleaning strip 505, as shown in FIG. Fig.12 As shown, the particles are cleaned in the opposite direction of the cable movement, which prevents the particles from contacting the cleaned cable again and affecting the service life of the cable surface.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
