Description

Technical Field

[0001] The present invention relates to the field of cable transportation, and more specifically, to a long-distance cable transportation device and a working method. Background Art

[0002] The cable transportation operations involved in port construction, urban communications, and power engineering are becoming more and more frequent, and the transportation environment is becoming more and more complicated. For conventional cable transportation work, cable conveyors are often used to assist. Cable conveyors are an electric machine used to lay large underground power cables or communication cables. They use rubber tracks on opposite sides to clamp and deliver cables. The tracks rely on friction to complete the forward transportation of cables under rotation. Cable conveyors are often used in large cable pipe laying, tunnel transmission, long-distance transportation and other operations. They have the advantages of convenient and fast operation, saving manpower and labor, and shortening construction period. However, existing cable conveyors can generally only be used on the ground and are suitable for conditions with relatively flat and mostly straight terrain, such as strip foundation pits, pipe galleries, mining projects and other working environments. Conventional cable conveyors are not applicable to port construction projects, high-altitude construction projects and other transportation scenarios that need to cross a certain space.

[0003] When handling communication cables and electrical cables in areas that cannot be reached directly, thinner cables can be carried to the area manually for operation, but thicker cables or cables with special cross-sections cannot be carried manually and need to be transported using brackets, pulleys and cable conveyors. This type of transportation method requires a large amount of pre-work and the cables are prone to bend and entangle over long distances and high ground distances. If additional guiding equipment and traction means are not added, it will not only be difficult to effectively carry out the cable transportation task, but also prone to safety hazards.

[0004] Up to now, the solution for delivering cables to areas that cannot be reached directly is still limited to using on-site support frames, car cranes, etc., which not only requires cumbersome preparatory work and high costs, but also has unsatisfactory delivery efficiency. Therefore, it is urgent to propose a new long-distance cable delivery device and a supporting method of use. Summary of the invention

[0005] An object of the present invention is to provide a long-distance cable conveying device and a working method, which has the characteristics of a large conveying range, a high conveying height, and fast cable conveying, and is suitable for cables of various sizes.

[0006] In order to achieve these purposes and other advantages according to the present invention, in the first aspect, the present invention provides a long-distance cable conveying device, comprising: a rotating disk mechanism, which can rotate in a horizontal plane; an arm mechanism, which is a long strip structure, one end of the arm mechanism is hinged to the top of the rotating disk mechanism, and the other end extends outward, and the arm mechanism rotates in a vertical plane with the hinge point with the rotating disk mechanism as the axis; a cable conveyor, which is installed at the two ends of the arm mechanism, and the cable conveyor is two stacked conveyor belt mechanisms, and the conveyor belts of the two conveyor belt mechanisms of the cable conveyor move in opposite directions and at the same speed, the relative belt surfaces of the two conveyor belt mechanisms clamp the cable and rely on friction to drive the cable forward, and all cable conveyors clamp the cable together and transport it in one direction along the length direction of the arm mechanism.

[0009] Preferably, the conveyor belt mechanism of the telescopic arm mechanism in the cable conveyor is an upper conveyor belt, and the conveyor belt surface on one side thereof is in contact with the conveyor belt surface of the other conveyor belt mechanism, and the two sides of the inner circle of the upper conveyor belt are upper conveyor belt main rollers, and the two upper conveyor belt main rollers tighten the upper conveyor belt in the length direction and drive the upper conveyor belt to move in a circle, and the middle part of the upper conveyor belt main roller is reduced in diameter to form a main roller reduction zone, and its diameter is smaller than other parts of the upper conveyor belt main roller, wherein, when the cables are clamped in the two conveyor belt mechanisms for coordinated movement, the contact surface between the upper conveyor belt and the other conveyor belt mechanism is partially concave due to the action of the cable and the space of the main roller reduction zone.

[0010] Preferably, a row of lower pressure rollers are provided in the annular belt body of the upper conveyor belt, and the lower pressure rollers can rotate along their own long axes. The bottoms of the lower pressure rollers press the belt surface of the upper conveyor belt close to the arm mechanism side flat against the belt surface of the other conveyor belt mechanism, and the middle part of the lower pressure rollers is reduced in diameter to form a reduced diameter area of ​​the lower pressure rollers.

[0011] Preferably, the conveyor belt mechanism between the upper conveyor belt and the arm mechanism is a chain conveyor belt, and the belt surface of the chain conveyor belt in contact with the upper conveyor belt is always straight.

[0013] Preferably, the cable is one or more cables bundled together.

[0014] In a second aspect, the present invention provides a working method of a long-distance cable conveying device, which is applied to the long-distance cable conveying device and comprises the following steps: S1. Keep the arm mechanism folded on the ground, pass the end of the cable through the cable guide on the first arm, and then insert the end of the cable into one end of the cable conveyor on the first arm. The cable is discharged from the other end of the cable conveyor under the friction between the upper conveyor belt and the chain conveyor belt; S2, manually insert the end of the cable passing through the cable conveyor on the first arm into all the cable guides in sequence, and then insert it into the cable conveyor on the extension arm, and the end of the cable extends out from the last cable guide; S3, stopping the operation of the cable conveyor located on the extended arm, keeping the cable in the stopped state, and the cable conveyor located on the first arm continues to transport the cable forward for a certain distance, so that the cable leaves a protective length between the cable guides; S4.

The aerial workers only need to wait for the ground to be installed, and then extend the arm to the working area to conveniently receive the transmitted cable. Moreover, since the extended arm of the device has the ability to move freely through the cooperation of the arm mechanism and the rotating disk mechanism, the continuous multi-point conveying of the aerial cable can be completed when the device position is different; Second, the long-distance cable conveying device of the present invention, wherein the cable conveyor is a double conveyor belt mechanism stacked up and down, is suitable for cables of various types and sizes, and can fully convey multiple cables at the same time, and has a high conveying speed for the cables; Third, for the long-distance cable conveying device of the present invention, for thinner cables, it is only necessary to open the cable conveyor on the receiving cable side and release the contact relationship between the two conveyor belt mechanisms of the cable conveyor on the other side. The cable only receives tension during the conveying process and is guided by the cable guide during the conveying process. The cable will not bend during the conveying process.

[0016] Fourth, since both ends of the boom mechanism are equipped with cable conveyors, after the cable installation is completed, both ends can complete the cable transportation, and the cable can be transported from a low position to a high position. When reverse transportation is required, it is only necessary to connect the high-position cable to be transported with the cable end extending out of the extended arm for reverse transportation.

[0017] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 13 As shown, the present invention provides a long-distance cable conveying device, comprising: a rotating disk mechanism 3, which can rotate in a horizontal plane; an arm mechanism 4, which is a long strip structure, one end of the arm mechanism 4 is hinged to the top of the rotating disk mechanism 3, and the other end extends outward, and the arm mechanism 4 rotates in a vertical plane with the hinge point with the rotating disk mechanism 3 as the axis; a cable conveyor 2, which is installed at the two ends of the arm mechanism 4, and the cable conveyor 2 is two stacked conveyor belt mechanisms, and the conveyor belts of the two conveyor belt mechanisms of the cable conveyor 2 have opposite directions of circumferential motion and the same speed, and the relative belt surfaces of the two conveyor belt mechanisms clamp the cable 1 and rely on friction to drive the cable forward, and all cable conveyors 2 clamp the cable 1 together and transport it unidirectionally along the length direction of the arm mechanism 4.

[0024] In the present technical solution, the rotating disk mechanism 3 is a disc-shaped rotating table, and its bottom is a rotating seat chassis 34. The rotating seat chassis 34 is fixed on a leg that is easy to change its position or a movable vehicle. The surface of the rotating disk mechanism 3 is in a horizontal state during operation. A rotating shaft mechanism is provided on the rotating seat chassis 34, including a rotating shaft inner ring 33 and a rotating shaft outer ring 32 that are rotatably connected by a bearing. The rotating shaft inner ring 33 is fixed on the rotating shaft chassis 34. The rotating disk mechanism 3 is detachably connected to the rotating shaft outer ring 32 by means of high-strength bolts or the like. An outer ring toothed belt 321 is provided on the outer circumference of the rotating shaft outer ring 32. A rotating disk motor 30 is fixedly installed on the outer side of the rotating shaft chassis 34, and a driving gear 301 is connected to its top for transmission. The driving gear 301 cooperates with the transition gear 302 to form a meshing relationship with the outer ring toothed belt 321. The rotating disk motor 30 drives the driving gear 301, the transition gear 302, and the rotating shaft outer ring 32 to rotate, thereby driving the arm mechanism 4 to complete horizontal steering.

[0025] In the present technical scheme, the arm mechanism 4 can be a single extendable arm structure or a multi-layer folding arm system. The cable conveyor 2 is a conveyor belt structure that is easy to process. Each cable conveyor 2 completes the transportation of a single or multiple cables 1 through the relative moving belt surfaces of two conveyor belt mechanisms. Since cable conveyors 2 are provided at both ends of the arm mechanism 4, the cable 1 can be subjected to only tension but not compression between the arm mechanisms 4 without bending. The cable 1 takes one end of the arm mechanism 4 hinged to the rotating disk mechanism 3 as the transportation starting point, and the cable 1 can be smoothly transported to the other end. One end of the arm mechanism 4 is hinged to the rotating disk mechanism 3. The arm mechanism 4 can cooperate with devices such as an actuator to complete the lifting operation of the arm mechanism 4 in the vertical direction. In conjunction with the horizontal rotation of the rotating disk mechanism 3, the cable 1 can be transported to most positions within a spherical space, which is suitable for transporting the cable 1 under complex terrain.

[0026] In another technical solution, the arm mechanism 4 includes a first arm 41, one end of which is hinged to the top of the rotating disk mechanism 3, and the other end is hinged outwardly with at least one intermediate arm 42 and an extending arm 43, one end of the extending arm 43 is a free end and the other end is hinged to the end of the outermost intermediate arm 42; a first actuating cylinder 411, one end of the first actuating cylinder 411 is hinged to the top of the rotating disk mechanism 3, and the other end is hinged to the middle of the first arm 41; a plurality of second actuating cylinders 421, the middle of the arm body of the first arm 41 and the intermediate arm 42 are hinged to one end of the second actuating cylinder 421, and the other end of the second actuating cylinder 421 is hinged to the intermediate arm 42 extending to the adjacent intermediate arm 42. The arm 42 or the arm body of the extended arm 43; wherein, the cable conveyor 2 is installed on the first arm 41 and the extended arm 43. In the present technical solution, the first actuator 411 and the second actuator 421 are telescopic structures such as finished hydraulic rods that are easily available on the market, and coordinated operations are performed through a mature control system. The angle between any two adjacent structures among the first arm 41, the middle arm 42, and the extended arm 43 can be changed by extending or contracting the first actuator 411 and the second actuator 421. The conveying range of the cable 1 is flexible. Optionally, the first arm 41, the middle arm 42, and the extended arm 43 can be designed to be fully foldable to facilitate the transportation of the present invention.

[0027] In another technical solution, a cable guide 5 is fixed on the entire arm of the middle arm 42, and the arm bodies of the first arm 41 and the extending arm 43 are provided with cable guides 5 at the front and rear ends of the cable conveyor 2. The cable guide 5 is a ring-shaped or tubular structure, and the cable 1 is sequentially passed through all the cable guides 5 along the arm frame mechanism 4. In this technical solution, the cable guide 5 is a ring-shaped or tubular structure, and the edges and surfaces of the cable guide 5 that are in direct contact with the cable 1 need to be properly bent to avoid stress concentration. Since the first arm 41, the middle arm 42, and the extending arm 43 will inevitably produce angle changes with each other during the activities, in order to prevent the cable 1 from bending and entanglement, a limiting device for the cable 1 needs to be provided on each arm body, and the cable 1 is inserted into all the cable guides 5, and will only be transported along the cable guide 5 when the cable 1 is pulled or pushed.

[0028] In another technical solution, the conveyor belt mechanism of the telescopic boom mechanism 4 in the cable conveyor 2 is an upper conveyor belt 21, and the conveyor belt surface on one side thereof is in contact with the conveyor belt surface of the other conveyor belt mechanism. The two sides of the inner circle of the upper conveyor belt 21 are upper conveyor belt main rollers 211. The two upper conveyor belt main rollers 211 tighten the upper conveyor belt 21 in the length direction and drive the upper conveyor belt 21 to move in a circle under the drive of the upper conveyor belt motor 210. The middle part of the upper conveyor belt main roller 211 is reduced in diameter to form a main roller reduction zone 2110, and its diameter is smaller than other parts of the upper conveyor belt main roller 211. When the cable 1 is clamped in the two conveyor belt mechanisms for coordinated movement, the contact surface between the upper conveyor belt 21 and the other conveyor belt mechanism is partially concave due to the action of the cable 1 and the spatial influence of the main roller reduction zone 2110. In the present technical solution, the unreduced roller surface of the upper conveyor belt main roller 211 presses the upper conveyor belt 21 onto the belt surface of the lower conveyor belt mechanism. The lower conveyor belt mechanism can be a lower conveyor belt 20 that also adopts a belt transmission method. The lower conveyor belt main roller 201 used for tightening and driving the lower conveyor belt 20 under the drive of the lower conveyor belt motor 200 can be a hollow cylindrical structure. The belt surface of the lower conveyor belt 20 is always straight. When the cable 1 enters between the two conveyor belt mechanisms, only the upper conveyor belt 21 produces elastic concave deformation due to the shape of the upper conveyor belt main roller 211, and because the belt body of the upper conveyor belt 21 is always in a taut state in the length direction, the concave upper conveyor belt 21 still has a good friction effect on the cable 1. By setting the main roller reduction area 2110, the device does not need to adjust the distance between the two conveyor belt mechanisms in the cable conveyor 2 according to the size of the cable 1, and the device is suitable for conveying cables 1 of any conventional size.

[0029] In another technical solution, a row of lower pressure rollers 212 are arranged in the ring-shaped belt body of the upper conveyor belt 21, and the lower pressure rollers 212 can rotate along their own long axes. The bottom of the lower pressure rollers 212 presses the belt surface of the upper conveyor belt 21 close to the arm mechanism 4 to the belt surface of the other conveyor belt mechanism. The middle part of the lower pressure rollers 212 is reduced in diameter to form a lower pressure roller reduction area 2120. A row of belt supporting rollers 202 are arranged between the ring-shaped belts of the lower conveyor belt 20, which are used to support the belt surface of the lower conveyor belt 20 to prevent it from being deformed under the action of the cable 1. The belt supporting rollers 202 are cylindrical. When the cable 1 is clamped between the upper conveyor belt 21 and the lower conveyor belt 20, the middle part of the upper conveyor belt 21 is forced to be deformed.

[0030] In another technical solution, the conveyor belt mechanism between the upper conveyor belt 21 and the arm mechanism 4 is a chain conveyor belt 23, and the belt surface of the chain conveyor belt 23 in contact with the upper conveyor belt 21 is always straight, wherein the chain conveyor belt 23 is an endless belt composed of multiple hard half-pieces hinged to each other, and two sets of drive chains 231 are installed on the inner circumference of the ring of the chain conveyor belt 23, and the two sides of the drive chain 231 are chain belt side supports 232, and two sets of drive gear sets 2301 are installed on the bearings between the two chain belt side supports 232, and the two sets of drive gear sets 2301 are matched and meshed with the drive chains 231 to straighten the chain conveyor belt 23, and the drive gear sets 2301 are connected between the plate belt motor 230 and the coupling 2 The belt conveyor 23 is driven by the drive chain 231 and the chain conveyor belt 23, and a plurality of side plate connecting beams 233 are installed between the side supports 232 of the chain conveyor belts on both sides. Two roller bearing support beams 2331 are fixed on the side plate connecting beams 233 parallel to the belt conveyor belt 23. A row of roller shaft fixing blocks 2332 are arranged at intervals on each roller bearing support beam 2331. A chain plate supporting roller 2333 is installed on the bearing between the two opposite roller shaft fixing blocks 2332. The chain plate supporting roller 2333 supports the inner side of the belt surface of the chain conveyor belt 23 to further prevent the chain conveyor belt 23 from being deformed under force. Optionally, a rubber layer is provided on the surface of the chain conveyor belt 23 to increase friction.

[0031] In the present technical solution, if the belt surface of the conveyor belt mechanism below is deformed during the conveying process of the cable 1, the cable 1 may easily shift or even bend and entangle. Even if a belt supporting roller 202 is provided, the belt surface of the belt-type conveyor belt mechanism may be deformed in the belt surface area not directly supported by the belt supporting roller 202. Therefore, the conveyor belt mechanism below adopts a chain conveyor belt 23, and the cable 1 is sandwiched between the surface-rigid chain conveyor belt 23 and the adaptively deformable upper conveyor belt 21. While being subjected to good friction, the risk of cable 1 shifting or bending caused by the simultaneous deformation of the upper and lower belts is avoided.

[0032] In another technical solution, the bearings at both ends of the upper conveyor belt main roller 211 and the lower pressure roller 212 are connected to the conveyor belt side supports 22, and a group of lifting mechanisms 6 are arranged on both sides of the chain conveyor belt 23, and the lifting mechanisms 6 include mutually parallel strip bottom plates 60 and lifting beams 61, and the lifting beams 61 are connected to the conveyor belt side supports 22 on the corresponding sides, and the strip bottom plates 60 are fixed on both sides of the chain conveyor belt 23. The lifting beams 61 can change the distance between them and the strip bottom plates 60 under external drive, wherein, when the upper conveyor belt 21 is in contact with the surface of the chain conveyor belt 23, the distance between the lifting beams 61 and the strip bottom plates 60 is increased, the upper conveyor belt 21 is separated from the chain conveyor belt 23, and the cable 1 does not generate force on the cable conveyor 2.

[0033] In this technical solution, if Figure 9~Figure 10 As shown, the lifting mechanism 6 is a rack and pinion lifting mechanism, and the strip bottom plate 60 is connected to the outer side of the chain plate belt side support 232, and each side of the strip bottom plate 60 Two lifting arms 62 are symmetrically arranged between the lifting beam 61, which include a support hinge 621, a first rotating arm 622, and a second rotating arm 623. The support hinge 621 is a hinge block structure, which is located on one side of the first rotating arm 622 and is hinged to the lower end of the first rotating arm 622. A rotating arm gear 6222 is fixed to the other side of the first rotating arm 622. The upper end of the first rotating arm 622 is hinged to the lower end of the second rotating arm 623, and the upper end of the second rotating arm 623 is hinged to the lifting beam 61. The symmetrical rotating arm gears 6222 on the same lifting mechanism are jointly driven and meshed on a moving bottom beam with strip teeth 640 at both ends, wherein the moving bottom beam 64 is a Z-shaped structure, including a bottom beam lower arm 641 and a bottom beam upper arm 642 attached to the strip bottom plate 60. The strip bottom plate 60 A limit block 65 is installed on the top, and the lower arm 641 of the bottom beam is inserted into 65 so that the movable bottom beam 64 can only perform linear motion. The top surface of the end of the lower arm 641 of the bottom beam is provided with a strip tooth 640, and the lower surface of the upper arm 642 of the bottom beam is provided with a strip tooth. When the movable bottom beam 64 moves, the symmetrical first rotating arm 622 in the lifting mechanism 6 rotates relative to or oppositely under the drive of the rotating arm gear 6222, so that the lifting beam 61 supported by the lifting arm 62 is lifted or lowered, completing the contact and separation between the upper conveyor belt 21 and the chain conveyor belt 23, wherein the two chain belt side supports 232 are provided with reserved movable openings 2320, and an actuating beam 67 is connected between the movable bottom beams 64 on both sides through the reserved movable openings 2320, and a third actuating cylinder 66 is connected between a side plate connecting beam 233 and the actuating beam 67, and the third actuating cylinder 66 controls the lifting mechanism 6 by extending and shortening.

[0034] In another technical solution, the cable 1 is one or more mutually bundled cables. Since the upper conveyor belt 21 can adapt to cables of conventional size and shape and still exert good friction, multiple cables 1 can be transported at the same time. During the transportation process, manual cooperation is required to use adhesive tape or binding tape to tighten the cables transported at a certain distance to avoid the cables running during transportation.

[0035] In another technical solution, the working method of the long-distance cable conveying device includes the following steps: S1, keep the arm mechanism 4 in the folded state on the ground, pass the end of the cable 1 through the cable guide 5 located on the first arm 41, and then insert the end of the cable 1 into one end of the cable conveyor 2 on the first arm 41. The cable 1 is discharged from the other end of the cable conveyor 2 under the friction of the upper conveyor belt 21 and the chain conveyor belt 23; specifically, when the arm mechanism 4 is folded on the ground, the wire guide work can be conveniently performed manually. Optionally, as Figure 4As shown, the tooling connected with bearings at both ends of the cable drum 11 wound with the cable 1 can be fixedly installed on the rotating disk mechanism 3.

[0036] S2. Manually insert the end of the cable 1 that has passed through the cable conveyor 2 on the first arm 41 into all the cable guides 5 in sequence, and then insert it into the cable conveyor 2 on the extending arm 43. The end of the cable 1 extends out from the last cable guide 5. Specifically, during the lead-in, since the cable 1 is only provided with forward force by the cable conveyor 2 at the tail section, the ground personnel are required to hold the cable 1 and cooperate in the threading until the head of the cable 1 enters the cable conveyor 2 on the extending arm 43. After the end of the cable 1 extends out from the cable conveyor 2 on the extending arm 43, the cable 1 is temporarily fixed to the cable guide 5 at the very end.

[0037] S3. Stop the operation of the cable conveyor 2 located on the extended arm 43, keep the cable 1 in a stopped state therein, and the cable conveyor 2 located on the first arm 41 continues to transport the cable forward for a certain distance, so that a protective length of the cable 1 is left between the cable guides 5. Specifically, in order to prevent the arm mechanism 4 from stretching the cable 1 during the replacement action, it is necessary to form a redundant length area 100 between the two sections of the cable conveyor 2, so that when the angle between the arm sections of the arm mechanism 4 changes, the cable 1 can be adaptively adjusted without being stretched.

[0038] S4. Under the coordinated drive of the rotating disk mechanism 3, the first actuator 411, and the second actuator 421, the extending arm 43 is stopped near the preset cable release area, the cable conveyor 2 on the extending arm 43 is turned on, and the upper conveyor belt 21 in the cable conveyor 2 on the first arm 41 is lifted to transport the cable 1 from the ground to one side of the extending arm 43.

For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
