Description

Technical Field

[0001] Cables are typically rope-like structures made of several or groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables mainly consist of conductive cores, insulation layers, sealing sheaths, and protective covering layers. Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, such as overhead, underground (pipes and direct burial), underwater, wall, and tunnel laying. Power cables are usually transported using wooden or steel reels.

[0002] Larger cables are typically transported using steel reels. Due to the size and weight of the cable reels, a cable unloading device is needed during cable laying to support the reel and pull out the cable. Because of the large weight of both the cable reel and the cable, cable unloading operations are usually performed using a trolley. However, existing trolleys, due to the large weight of the cable reels, require forklifts or cranes for loading. Furthermore, because the spacing between trolleys is fixed, one trolley can only handle one size of cable reel, limiting its usability.

[0003] During the laying process, the initial cable weight is relatively large, requiring active driving of the cable reel to pull it off the cable cart. However, during this pulling process, due to cable stress, the cable may loosen on the reel. This loosening accelerates the rotation of the cable reel, and if left unchecked, the high-speed rotation of the reel can easily cause it to detach from the operating cart, posing a significant danger.

[0004] The existing intervention measure is to control the drive device to reverse. Since the brake is applied at the center of the cable reel, the existing operating vehicles cannot easily control the cable reel due to its large overall mass, resulting in significant safety risks during the laying operation.

Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of existing technologies in which cables are dangerous during the laying process, and to provide a multifunctional cable laying device.

[0010] This invention is achieved through the following technical solution: a multifunctional cable laying device, comprising, The vehicle frame serves as a mobile carrier, with wheels at the bottom and a steering structure at the front.

[0011] Furthermore, the frame has a U-shaped structure, an opening at the rear of the frame, and multiple support legs on the sides of the frame.

[0012] Furthermore, the support structure includes vertically mounted uprights on the frame, with two sets of uprights arranged opposite each other on both sides of the frame. Each upright has an internal sliding groove with a T-shaped cross-section. An opening groove communicating with the sliding groove is provided on the side of the upright. A limiting block is slidably mounted inside the sliding groove, with its side extending out of the groove. A lifting rod for supporting the cable reel is provided on the side of the upright.

[0013] Furthermore, the side of the lifting rod is fixedly connected to the limiting block, and the side of the lifting rod is provided with a snap-fit ​​groove for connecting the cable reel.

[0014] Furthermore, a lifting cylinder is provided on the side of the lifting rod, the top of the lifting cylinder is connected to the lifting rod, and the bottom of the lifting cylinder is connected to the vehicle frame.

[0015] Furthermore, the bottom of the support rod is hinged to the vehicle frame, the mounting bracket is disposed on the top of the support rod, a control cylinder is disposed on the side of the support rod, the top of the control cylinder is hinged to the upper part of the support rod, and the bottom of the control cylinder is rotatably connected to the vehicle frame.

[0016] Furthermore, a first hinge seat is provided at the bottom of the support rod, and the support rod is hinged to the upper part of the first hinge seat. The first hinge seat is connected to the frame by bolts. The frame is provided with a plurality of first mounting holes for connecting the first hinge seat. A second hinge seat is provided at the bottom of the control cylinder, and the second hinge seat is connected to a second mounting hole provided on the frame. The first hinge seat and the second hinge seat are arranged on the same straight line.

[0017] Furthermore, the drive unit is an electric motor or a hydraulic motor, a speed reducer is provided on the side of the mounting bracket, the drive wheel is located inside the mounting bracket and abuts against the top surface of the side plate of the cable reel, the speed reducer is connected to the output end of the drive unit, a gear set is provided inside the speed reducer and connected to the intermediate shaft of the drive wheel, and an adjusting rod for adjusting the spacing is provided between the two mounting brackets.

[0018] Furthermore, the brake structure includes a connection hole provided on the mounting bracket, and a high-pressure gas cylinder is detachably provided on the upper part of the connection hole; A positioning tube is detachably provided at the lower part of the connection hole, a primer block is provided at the top of the positioning tube, and a striking pin for releasing the gas inside the high-pressure gas cylinder is provided on the upper surface of the primer block. The mounting bracket is equipped with a terminal block, which is electrically connected to an independent power source. The other end of the terminal block is connected to the primer block. A brake lever is provided inside the positioning tube, a piston block is provided at the top of the brake lever, the piston block abuts against the inside of the positioning tube, a rubber block is provided at the bottom of the brake lever, and the brake lever is located above the top surface of the side plate of the cable reel.

[0019] Furthermore, the power unit is a hydraulic station, which is located at the front end of the vehicle frame.

[0020] The beneficial effects of this invention are as follows: 1. The U-shaped frame with a closed front and an open rear allows for direct loading of cable reels from the side or rear, making operation simple. The frame is equipped with retractable outriggers that brace against the ground during operation to form a stable platform, effectively preventing the cable reel from tipping over due to a shift in its center of gravity, thus ensuring operational safety and stability.

[0021] 2. The support structure employs a lifting rod with multiple sets of locking slots, coupled with an adjustable-height lifting cylinder, to accommodate cable reels of different diameters. The installation spacing of the drive structure can be adjusted via multiple sets of mounting holes on the frame, allowing it to match cable reels of different widths, significantly expanding the applicability of the device.

[0022] 3. Employing an outer-edge drive method, the drive wheel presses against the top circumference of the cable reel's side plate, utilizing friction to drive rotation. Compared to traditional center-shaft drives, this method has a larger lever arm, enabling efficient driving of large-mass cable reels with less torque, reducing energy consumption and simplifying operation.

[0023] 4. The independently designed braking structure utilizes a high-pressure gas cylinder and a trigger-type impact braking design. When the cable reel accelerates abnormally or loosens, an electrical signal instantly triggers the brake lever to depress at high speed, generating a large braking torque on the long lever arm for rapid braking. This system is independently powered, allowing it to continue operating even if the main power source fails, significantly improving safety and reliability in emergency situations.

[0024] 5. A hydraulic system is used to power the lifting, driving, and adjusting mechanisms, providing high output force, convenient speed adjustment, and adaptability to harsh construction site environments. If a hydraulic motor is selected as the drive unit, no additional generator is required, resulting in high integration and sensitive operation response.

[0025] 6. The high-pressure gas cylinder, positioning tube, brake lever, and other components in the braking structure adopt a modular design, allowing for quick replacement after triggering and reducing maintenance downtime. After completing the operation, the outriggers can be retracted and the cable reel lowered for easy transfer to the next work point, improving the efficiency of continuous operation.

[0027] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0029] like Figure 1-9 As shown, this invention proposes a multifunctional cable laying device, mainly comprising a frame 1, a support structure for supporting cable reels 4, a drive structure, a braking structure, and other components. The frame 1 serves as the basic load-bearing and moving platform for the entire device, adopting a U-shaped frame structure with a closed front and an open rear, facilitating reel loading operations from the side or rear of the cable reels 4. Wheels are installed at the bottom of the frame 1, and a steering mechanism 102 is integrated at the front, allowing the device to be flexibly moved to various work points like a trailer. To enhance stability during operation and prevent overturning due to the shift in the center of gravity of the cable reels 4, multiple retractable outriggers 101 are hinged to both sides of the frame 1. The outriggers 101 can be hydraulically or mechanically driven to ensure the stability of the frame 1. After reaching the work position, the outriggers 101 are lowered and braced against the ground, providing stable support for the frame 1 and forming a temporary fixed working platform.

[0030] The support structure is vertically mounted on the upper part of both sides of the U-shaped opening on the frame 1. Its main function is to accommodate and support cable reels 4 of different diameters and widths. This structure includes two opposing uprights 2. To improve stability, reinforcing rods are fixed to the sides of each upright 2 to ensure stability during the lifting and lowering of the cable reel 4. Each upright 2 has a longitudinally continuous T-shaped cross-section groove 201 machined inside, and its side wall has a strip-shaped opening slot communicating with the groove 201. A T-shaped limiting block with a matching cross-sectional shape is embedded in the groove 201 and can slide up and down along it. The lifting rod 202 is slidably connected to the groove 201 through the limiting block.

[0031] The protruding part of the limiting block is fixedly connected to the external lifting rod 202. The side of the lifting rod 202 is provided with a snap-fit ​​groove 204 for connecting the cable reel 4. The lifting rod 202 is a rectangular rod. The snap-fit ​​groove 204 is provided on the side of the lifting rod 202 facing the rear of the frame 1 and on the opposite side of the two lifting rods 202. Multiple sets of snap-fit ​​grooves 204 are provided at different heights on the lifting rod 202 to accommodate cable reels 4 of different diameters. The lifting rod 202 is driven by a lifting cylinder 203 mounted on the frame 1. When it is necessary to load the cable reel 4, the lifting cylinder 203 is operated to make the limiting blocks on both sides descend synchronously to the lowest position. A wire feeding shaft 205 is inserted into the center of the cable reel 4. The length of the wire feeding shaft 205 is fixed, which facilitates the connection between the two ends of the wire feeding shaft 205 and the snap-fit ​​groove 204. A connecting block is provided on the wire feeding shaft 205. When the wire feeding shaft 205 is connected to the cable reel 4, the connecting block limits the cable reel 4 to the middle position of the wire feeding shaft 205, which facilitates the placement of the cable reel 4 on the frame 1 and ensures the stability during wire feeding.

[0032] After the cable reel 205 is fixed, the control frame 1 is used to guide the cable reel 4 from the rear of the frame 1 between the two lifting rods 202. The height of the lifting rods 202 is adjusted so that both ends of the cable reel 205 are engaged through the openings on the side of the locking grooves 204. Then, the lifting cylinder 203 is controlled to lift the cable reel 205 so that both ends of the cable reel 205 are inserted into the bottom of the locking grooves 204. The locking grooves 204 on both sides of the lifting rods 202 are opened to a certain depth to fix the ends of the cable reel 205 and ensure stability during use. Then, the lifting cylinder 203 is controlled to extend and lift the lifting rods 202. The entire cable reel 4 is lifted off the ground and raised to a suitable working height. Through the precise control of the lifting cylinder 203, the center height of the cable reel 4 can be adjusted to better match the drive structure. The cooperation between the T-shaped slide 201 and the limit block ensures the stability of the load and effectively resists the left and right swaying of the cable reel 4.

[0033] The drive structure is responsible for actively driving the heavy cable reel 4 to rotate during laying to overcome starting inertia. This structure mainly includes a pair of swingable support rods 301 mounted on the front end of the frame 1. The bottom end of the support rod 301 is connected to the frame 1 via a first hinge seat 302, allowing it to swing back and forth like a boom. A mounting bracket 5 is mounted on the top of the support rod 301, providing installation space. The mounting bracket 5 has a U-shaped cross-section, with its bottom facing the front of the frame 1. The mounting bracket 5 integrates a drive unit 501, such as a hydraulic motor or electric motor, a reducer 502, and drive wheels 504. The drive wheels 504 are typically made of wear-resistant rubber. The intermediate shaft of the drive wheels 504 is rotatably mounted at both ends of the mounting bracket 5. Two or three drive wheels 504 are provided to increase the contact area with the bottom surface of the cable reel 4's side plate, facilitating better control of the cable reel 4's movement. The reducer 502 is installed on the outer side of the mounting bracket 5. Inside the reducer 502, there is a gear set that is connected to the intermediate shaft of the drive wheel 504. The reducer 502 is connected to the drive unit 501 to provide power to the drive wheel 504 and ensure that the drive wheel 504 moves in the same direction.

[0034] A control cylinder 3 is mounted on the side of the support rod 301. The top of the control cylinder 3 is hinged to the upper part of the support rod 301, and the bottom of the control cylinder 3 is connected to the frame 1. By controlling the extension and retraction of the control cylinder 3 on the side of the support rod 301, the tilt angle of the support rod 301 can be adjusted, so that the drive wheels 504 on the two drive mounting brackets 5 can press down and press against the top circumference of the side plates of the raised cable reel 4. The torque generated by the drive unit 501 is amplified by the reducer 502 and transmitted to the drive wheels 504. Relying on the friction between the drive wheels 504 and the top surface of the side plates of the cable reel 4, the entire cable reel 4 is driven to rotate. This "outer edge drive" method, which drives from the maximum circumference of the cable reel 4, i.e., the outer edge of the side plate, can obtain a larger lever arm compared with the traditional drive center shaft method, thus achieving the drive of the large-mass cable reel 4 with a smaller torque output, which is more labor-saving and efficient.

[0035] The first hinge seat 302 at the bottom of the two support rods 301 and the second hinge seat 304 at the bottom of the control cylinder 3 are both connected to the frame 1 by bolts. Multiple sets of mounting holes are pre-drilled along the width of the frame 1. The first hinge seat 302 mates with the first mounting hole 303, and the second hinge seat 304 mates with the second mounting hole 305. By changing the fixed positions of the first hinge seat 302 and the second hinge seat 304, the reference distance between the two drive wheels 504 can be adjusted, thereby adapting to cable reels 4 of different widths and greatly expanding the applicability of the device. To ensure the stability between the two mounting brackets 5, an adjusting rod 6 is movably installed between the two mounting brackets 5. The adjusting rod 6 adopts an adjustable connection structure; the distance between the two mounting brackets 5 is adjusted by rotating the threaded sleeve in the middle, making adjustment convenient and the structure stable.

[0036] The entire device is powered by a hydraulic station 103 integrated at the front of the chassis 1, which includes a lifting cylinder 203, a control cylinder 3, and a hydraulic motor that serves as the drive unit 501, supplying high-pressure hydraulic oil. A control station is also located at the front of the chassis 1 for operating the lifting cylinder 203, the control cylinder 3, and the hydraulic motor; the control cable reel 4 is also functional. Using a hydraulic system as the power source offers advantages such as high output power, ease of speed adjustment and remote control, and adaptability to harsh construction site environments. In this embodiment, the drive unit 501 is preferably a hydraulic motor. If an electric motor were used, a corresponding generator or a large-capacity battery pack would be required, which would be inconvenient.

[0037] The braking structure is independent of the drive system and is specifically designed for emergency braking in case of cable reel malfunction or sudden failure. The braking structure is integrated into the upper part of the mounting bracket 5. A vertical connection hole facing the side plate of the cable reel 4 is located on the drive mounting bracket 5. A high-pressure gas cylinder 503 filled with high-pressure nitrogen is installed at the upper part of the connection hole, and a positioning tube 7 is screwed into the lower part. An electrically operated primer block 701 is installed inside the top of the positioning tube 7, operating similarly to the ignition mechanism of a car airbag. Above it is a striking pin 702 mechanism that triggers the valve of the high-pressure gas cylinder 503. The primer block 701 is connected to a terminal 703 mounted on the mounting bracket 5 via a wire. The terminal 703 is powered by an independent battery to ensure operation even in the event of a drive system failure. During use, an emergency trigger button is installed on the frame 1 for easy braking in emergencies, ensuring safety. It can also be used with a remote control assembly for triggering via remote control, further enhancing operational convenience and safety.

[0038] The positioning tube 7 is equipped with a sliding brake lever 704. The top of the brake lever 704 has a piston that fits tightly against the inner wall of the positioning tube 7, and the bottom of the brake lever 704 has a heat-resistant rubber block 705 with a high coefficient of friction. In the non-braking state, the bottom of the brake lever 704 is slightly higher than the top surface of the side plate of the cable reel 4. In emergency situations such as the cable reel 4 accelerating due to loosening or drive system failure, the operator can operate the emergency trigger button or press the remote control to trigger the circuit, instantly detonating the primer block 701. The explosion of the primer block 701 pushes the firing pin 702 to open the valve of the high-pressure gas cylinder 503, and high-pressure gas instantly rushes into the positioning tube 7, pushing the piston to drive the brake lever 704 downwards with great speed and force, causing the rubber block 705 at its bottom to violently slam into the top surface of the side plate of the rapidly rotating cable reel 4. Through the powerful positive pressure and intense friction, a huge braking torque can be generated in a very short distance, forcing the cable reel 4 to stop rotating instantly. This type of intermittent impact braking, compared to the traditional method of applying friction force to the central axis, has a longer braking arm, extremely rapid response, and immediate braking effect, which can effectively curb runaway accidents.

[0039] The working principle is as follows: First, the cable reel 4 is loaded and its height adjusted via the lifting support structure. It is then towed to the working position by a tractor, and the outriggers 101 on both sides of the frame 1 are lowered to stabilize the frame 1 structure. The drive structure spacing is adjusted, and the support rod 301 is swung to press the drive wheel 504 against the side plate of the cable reel 4. The power supply in the braking structure is connected, and the power system is started, driving the cable reel 4 to rotate and release the cable. During normal cable release, the release speed can be controlled by adjusting the rotation speed of the drive unit 501. If abnormal acceleration or loosening of the cable reel 4 is detected, the emergency braking structure is immediately activated for instantaneous braking. After the operation is completed, the drive wheel 504 is released, the cable reel 4 is lowered, and the outriggers 101 are retracted, allowing the device to be moved to the work site or used for transportation. The high-pressure gas cylinder 503, positioning tube 7, primer block 701, and brake lever 704 in the braking system are all quick-replaceable components. After the braking system is triggered, spare parts can be quickly replaced, reducing maintenance pressure and improving performance. This embodiment achieves adaptation to various specifications of cable reels 4 and efficient driving of the outer edge. Through an independent emergency impact braking structure, it solves the braking problem when the large-mass cable reel 4 is loosened, significantly improving the safety, efficiency and applicability of cable laying operations.
