Description

Technical Field

[0001] This invention relates to the field of cable construction technology, and in particular to a multi-dimensional adjustable cable shifting machine. Background Technology

[0002] Cable lifting is a crucial step in the laying and maintenance of power cables. Cables often need to transition across different heights, such as from the ground to cable trenches or support frames. Due to the large diameter and heavy weight of medium and high voltage cables, manual or simple mechanical equipment is insufficient to ensure smooth lifting. Therefore, specialized cable lifting mechanisms have emerged to improve work efficiency and safety.

[0003] Patent application number 202411269362.0 discloses an auxiliary device for laying medium and high voltage power cables. This device achieves safe laying and lifting of medium and high voltage power cables through the coordinated operation of a cable conveying system and a cable lifting system. In the cable conveying system, a battery powers a motor, and a controller controls the motor's speed and direction. The motor transmits power to equidistantly arranged power conveying rollers via a sprocket mechanism (composed of a drive gear, gears, and a chain), causing the rollers to rotate synchronously to pull the cable forward. Simultaneously, the spring support column, with the aid of a shock-absorbing structure and adaptive adjustment device, bears the force, preventing damage to the cable due to excessive traction or bending stress. The base has casters (with brakes) and extendable... The telescopic rod facilitates flexible movement and fixation of the device. In the cable lifting system, the cable gripper clamps cables of different diameters by adjusting the angle of each joint. The scissor jack controls vertical lifting by ball screws (the ball screws have a self-locking function because the friction angle is greater than the helix angle, which can fix the lifting position). After the cable is lifted to the target height, the telescopic rod drives the cable gripper to move horizontally, transferring the cable to the designated position (such as a cable bracket). Finally, the cable is released by adjusting the bolts of the gripper joints, completing the entire laying or lifting operation. The cable laying can be carried out safely and efficiently without the need for multiple equipment conversions.

[0004] The shortcomings of existing technology include: poor equipment mobility, difficulty in handling and moving, requiring additional equipment for assistance, and lack of convenience in use. It can only lift cables vertically, not move them horizontally, failing to meet the procedural requirements of laying operations, which still requires manual labor by construction personnel.

Detailed Implementation

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Example 1: like Figures 1-8 As shown, a multi-dimensional adjustable cable shifting machine includes a frame 200 with an electric mobile cart 100 at the bottom. A pair of cable lifting arms 300 are provided on the front side of the frame 200. A lifting platform 400 is provided on the frame to drive the cable lifting arms to rise and fall. The upper part of the cable lifting arms 300 is connected to the top of the lifting platform 400. Support leg mechanisms 500 are provided at the four corners of the frame. The cable lifting arm 300 includes a fork arm 310, a fork arm connecting seat 320 and a fork arm mounting bracket 330. The fork arm is connected to the fork arm mounting bracket via the fork arm connecting seat. The fork arm 310 extends forward horizontally and a cable bracket 340 is provided on the fork arm 310.

[0022] The electric mobile vehicle is responsible for overall movement and basic support, ensuring flexible turning and stable driving in the narrow space of the utility tunnel, while also assisting in crossing small obstacles, providing a stable mobile platform for cable handling and placement.

[0023] The main body of the electric mobile vehicle is welded from high-strength steel, resulting in a lightweight structure with high torsional strength, capable of stably supporting the entire machine's weight and a maximum cable load of 100kg. The chassis is equipped with a high-torque drive motor and wear-resistant rubber tires with an anti-slip tread design to enhance grip on wet surfaces within the utility tunnel. Each of the four wheels has an independent motor, enabling on-the-spot turning or small-radius turning. The electric mobile vehicle can be remotely controlled, with a maximum remote control distance of 100m (in open environments) and a control distance of ≥50m in complex environments within the utility tunnel. The structure of this electric mobile vehicle is existing technology; its structure and principles will not be elaborated upon here.

[0024] In this embodiment, the cable tray 340 is arc-shaped, and a nylon plate is provided on the cable tray to reduce friction with the cable; the cable tray 340 is movable back and forth on the upper side of the fork arm, and the fork arm is provided with a drive device for driving the cable tray to move back and forth.

[0025] In this embodiment, the driving device includes a pair of sprockets 311 rotatably connected to both ends of the fork arm 310, with chains 312 mounted on the two sprockets. Rollers 341 are mounted at the bottom of the cable tray, which is connected to the chains. A first motor, a geared motor, is located at the rear end of the fork arm. The main shaft of the first motor is connected to the rear sprocket of the fork arm, which is directly mounted on the main shaft of the first motor. The first motor drives the sprocket to rotate, which in turn drives the chain to rotate. By controlling the forward and reverse rotation of the first motor, the cable tray moves back and forth along the length of the fork arm, thereby achieving longitudinal (front-back) movement of the cable. A nylon plate can also be laid on the upper side of the fork arm to reduce the noise generated by the cable tray rollers and provide a certain buffering effect for the cable tray.

[0026] In this embodiment, the fork arm connecting seat is movably mounted on the fork arm mounting frame, and the rear end of the fork arm is hinged to the fork arm connecting seat and can be flipped upwards. A vertical lead screw 331 is rotatably connected to the fork arm mounting frame 330, and a second motor 350 for driving the vertical lead screw to rotate is provided at the upper end of the fork arm mounting frame. A lead screw nut that works in conjunction with the vertical lead screw is connected to the fork arm connecting seat. A pair of vertical guide rails 332 located on both sides of the lead screw are provided on the fork arm mounting frame, and a slider that cooperates with the vertical guide rails is installed on the fork arm connecting seat. The second motor is a geared motor, which drives the lead screw to rotate, causing the fork arm connecting seat to move the fork arm up and down.

[0027] The lifting function of the cable lifting arm is suitable for situations where the height is limited in cable laying scenarios (such as a corridor height of 1.5m). When the lifting platform cannot raise the fork arm to a position close to 1.5m, a second motor and lead screw allow the fork arm to adjust its height over a short distance, lifting the cable to the target position. The lifting arm itself is designed for cable trenches with a relatively high height (around 1.5m), where personnel cannot easily work. The lifting arm enables short-distance lifting, compensating for the height limitations imposed by the fork arm's height.

[0028] In this embodiment, the fork arm mounting bracket has an inverted L-shaped design. The upper short side is fixed to the top of the lifting platform with 6 M10 bolts, and the middle is hollow to reduce material usage and lighten the weight of the fork arm mounting bracket. The chain is equipped with a connecting plate for connecting cable trays. The bottom of the cable tray is connected to the connecting plate with screws. The cable trays are available in different specifications and models, and the appropriate model can be selected according to the diameter of the cable and installed on the fork arm to increase the overall adaptability.

[0029] In this embodiment, the fork arm can rotate 90°, that is, change from a horizontal state to a vertical state. The horizontal state is the working position, and the vertical state is the storage position. Flipping the fork arm upwards to retract it can shorten the overall width of the equipment. A limiting hole is provided on the rear side of the fork arm, and a bolt hole is provided on the fork arm connecting seat, which aligns with the limiting hole when the fork arm is in the vertical state. The fork arm is fixed in the vertical state by bolts passing through the bolt hole and the limiting hole. When the fork arm is flipped downwards, the bottom plate of the fork arm connecting seat abuts against the bottom surface of the fork arm to keep it in a horizontal state.

[0030] In this embodiment, the lifting platform is a scissor lift. The scissor lift adopts a 4-layer scissor frame structure and is equipped with an electric push rod with a thrust of 10,000N. The scissor lift has two sets, each controlling two cable lifting arms. The length direction of the scissor frame is parallel to the width direction of the electric mobile vehicle. Mechanical limit blocks are installed at the maximum lifting height and maximum extension length, along with electronic limit sensors, providing double protection to ensure the scissor arm movements do not exceed limits and avoid structural damage. Compared with traditional cable laying equipment, the scissor lift has significant advantages in terms of function, structure, and performance parameters. Its functions are more flexible and precise, adapting to various complex laying tasks; its structure is lighter and more robust, facilitating movement and operation in confined spaces within pipe racks; and its performance parameters are more efficient and stable, providing reliable protection for high-voltage cable laying work.

[0031] In this embodiment, the support leg mechanism 500 includes a mounting bracket 510, a rotating bracket 520, a lifting leg 530, and a caster wheel 540. The mounting bracket 510 is connected to the frame 200. The rotating bracket 520 is rotatably connected to the mounting bracket 510, and the rotation center line of the rotating bracket is set vertically. The lifting leg 530 is movable up and down and connected to the rotating bracket 520. The caster wheel 540 is mounted on the lifting leg 530.

[0032] In this embodiment, a connecting plate 511 is connected to the mounting bracket 510, and the connecting plate is connected to the mounting bracket by bolts and nuts. A rotating shaft 522, which is rotatably connected to the connecting plate via a bearing 523, is fixedly connected to the upper part of the rotating bracket 520. The outer ring of the bearing mates with the inner hole of the rotating plate, and the inner ring of the bearing mates with the rotating shaft. A circular limiting plate, located above the connecting plate and rotatably engaging with it, is fixedly connected to the upper end of the rotating shaft. The circular limiting plate serves to hold the rotating shaft in place. A third motor 550 is provided on the upper part of the mounting bracket, and the main shaft of the third motor is coaxially connected to the rotating shaft. The coaxial connection can be achieved by having polygonal holes at the center of the circular limiting plate and at the upper end of the rotating shaft, with the main shaft of the third motor inserted into the polygonal holes, and the cross-section of which is also polygonal. The third motor 550 transmits power to the rotating bracket 520, controlling the angle between the support leg mechanism and the electric mobile vehicle.

[0033] In this embodiment, the rotating bracket 520 is provided with a vertical outer tube 521, and the lifting leg 530 is provided with a vertical inner tube 531 that slides with the vertical outer tube. A lead screw is provided inside the vertical outer tube, with its upper end rotatably connected to the upper end of the vertical inner tube. The lead screw extends into the middle of the vertical inner tube, and a lead screw nut that mates with the lead screw is connected to the upper end of the vertical inner tube. A fourth motor 560 is provided on the outer side of the upper end of the vertical outer tube to drive the lead screw to rotate. The main shaft of the fourth motor 560 is connected to the lead screw via a pair of meshing bevel gears. The fourth motor 560 transmits power to the lead screw, thereby adjusting the height of the lifting leg. The casters have a self-locking function. The support leg mechanism is used to provide auxiliary support for the moving machine during operation, and can also raise the high-chassis moving vehicle to a certain height to assist in overcoming obstacles encountered during travel.

[0034] Reinforcing ribs 570 are provided on the mounting bracket 510 and the lifting outrigger 530 to enhance the strength of the connection parts and ensure the stability of the structure.

[0035] The support leg mechanism features adjustable support angle and lifting height. The support angle between the support leg mechanism and the electric mobile vehicle can be adjusted according to actual operational needs. During cable lifting and positioning, a third motor adjusts the support leg to be perpendicular to the electric mobile vehicle, and a fourth motor adjusts the height of the lifting leg, bringing it into contact with the ground and raising the chassis mobile vehicle to a certain height, thus improving operational stability and safety. By adjusting the angle with the chassis and the lifting height, and equipped with self-locking casters, the support leg mechanism provides both operational support and obstacle-crossing assistance. Breaking through the limitations of traditional support structures' "single-dimensional adjustment," it can dynamically adjust according to ground flatness and obstacle height, improving operational stability and giving the equipment obstacle-crossing capabilities, thus expanding the equipment's applicable scenarios.

[0036] When the cable is on the conveyor (not shown in the figure), the height above the ground is 20-30 cm. Before lifting the cable, the casters are adjusted to contact the ground by the fourth motor, and then the lifting legs are rotated to a suitable angle by the third motor so that the lower part of the lifting legs passes under the cable, thereby extending the side support distance of the shifting machine and preventing the cable from tipping over when lifting it.

[0037] This invention relates to a multi-dimensional adjustable cable relocation machine, which is modular in design. The electric mobile vehicle is detachably connected to the frame, the frame is detachably connected to the lifting platform, the lifting platform is detachably connected to the cable lifting arm, and the support leg mechanism is detachably connected to the frame. These detachable connections are achieved through bolts and nuts. The modular design reduces equipment maintenance costs and facilitates transport and storage. Each module can be independently disassembled, transported, and maintained, reducing the difficulty of relocation, transport, and storage, as well as maintenance costs. Faulty modules can be replaced individually according to actual operational needs, improving the equipment's lifespan and economic efficiency.

[0038] Instructions for using the multi-dimensional regulating cable shifting machine: The underground corridor has multiple cable supports vertically, each holding several cables of different diameters. The cable supports range in height from 0.5m to 2m. If the cables are to be manually lifted and laid, this would require repeated work. Furthermore, the cables are heavy; a single cable section can weigh up to 100kg per meter, requiring at least four people working together to lift them. Since a single cable can be up to 700m long, even more people would be needed for lifting. However, the limited workspace prevents simultaneous work by multiple people. Furthermore, securing high-voltage cables to the supports at the top presents difficulties for personnel, posing safety hazards.

[0039] The multi-dimensional adjustable cable relocation machine moves to the working position in the underground corridor. The position of the relocation machine and the high-voltage cable to be laid is adjusted so that the fork arm is below the cable. Then, the support leg mechanism is deployed and adjusted to the appropriate angle and height to provide support for the equipment. The lifting platform is raised, moving the fork arm and the high-voltage cable to be lifted synchronously upwards to the height of the cable fixing bracket. Next, the first motor is started, transmitting power to the sprocket. The sprocket drives the belt, which pushes the high-voltage cable onto the cable fixing bracket via the cable tray. The operator uses a binding device to secure the high-voltage cable. Then, the lifting platform is lowered, moving the fork arm back to its original position, reducing the height of the support leg mechanism, and retracting the support leg mechanism to its original position. This completes the high-voltage cable lifting and positioning operation for one location. The operator then manipulates the relocation machine to the next working position, repeating the above process to complete the high-voltage cable lifting and positioning operation until all high-voltage cables in the corridor are laid.

[0040] Example 2: like Figures 9-10 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the cable lifting arm. In this embodiment, the cable lifting arm does not have a lifting function, but it does have a folding function.

[0041] In this embodiment, the rear end of the fork arm 310 is fixedly connected to the fork arm connecting seat 320 to form an L-shaped structure. The fork arm connecting seat 320 is hinged to the fork arm mounting bracket and can be rotated upwards by 180°. The lower part of the fork arm mounting bracket 330 is provided with a limiting baffle 333 for abutting against the back of the fork arm connecting seat to keep the fork arm connecting seat in a vertical state. During normal operation, the fork arm connecting seat 320 is in a downward flipped state, at which time the fork arm is extended; after use, the fork arm connecting seat 320 is rotated upwards by 180° to retract the fork arm.

[0042] In this embodiment, the fork arm connecting seat has a limiting hole below the hinge portion, and the fork arm mounting bracket has two bolt holes, one above the other, that mate with the limiting hole after the fork arm connecting seat is flipped into position. The fork arm mounting bracket is inverted L-shaped, with a vertical receiving groove in the middle of the vertical portion to accommodate the fork arm connecting seat, and a horizontal receiving groove in the horizontal portion to accommodate the fork arm after the fork arm connecting seat is flipped upwards. The fork arm connecting seat is fixed by bolts passing through the bolt holes and the limiting hole, wherein the upper bolt hole is used when the fork arm connecting seat is flipped upwards, and the lower bolt hole is used when the fork arm connecting seat is flipped downwards. The fork arm connecting seat 320 flips upwards 180° to retract the fork arm. In the retracted state, the fork arm fits perfectly into the horizontal receiving groove of the fork arm mounting bracket, and the fork arm connecting seat fits perfectly into the vertical receiving groove of the fork arm mounting bracket.

[0043] Unless otherwise stated, if any of the technical solutions disclosed in this invention specify a numerical range, then the disclosed numerical range is a preferred numerical range. Anyone skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this invention discloses only some numerical values ​​to illustrate the technical solutions of this invention. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this invention.

[0044] If this invention discloses or relates to mutually fixedly connected components or structural parts, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).

[0045] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this invention to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0046] Any component provided by this invention can be assembled from multiple individual components or can be a single component manufactured by a one-piece molding process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
