Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a cable reel and cable laying device with an autonomous braking device. Background Technology

[0002] As a key loading device in the cable transportation field, the all-iron disc plays an indispensable role in the loading and transportation of land-based power cables. It is also a core component of the on-site cable laying process, and its operational stability directly affects the efficiency and safety of power cable construction. Currently, the braking control of the all-iron disc mainly relies on manual operation by on-site construction workers using wooden boards. This traditional braking method has revealed many significant defects and shortcomings in practical applications, severely restricting construction quality and efficiency, and posing considerable safety hazards.

[0003] First, the outer surface of the all-iron disc is coated with paint for corrosion protection, making the contact surface too smooth and resulting in insufficient friction, making it difficult to achieve a stable and effective braking effect during manual braking. Second, to increase friction for braking, the contact pressure between the wooden board and the all-iron disc must be increased during construction. This process wears off the anti-corrosion paint on the disc's surface, damaging its protective structure, accelerating corrosion and wear, and shortening its service life. Third, the force of manual braking relies entirely on the experience and feel of the construction workers, making precise control impossible. This leads to unstable laying speed, affecting construction quality, slowing down on-site progress, and reducing construction efficiency.

[0004] Meanwhile, manual braking requires extremely high levels of concentration from construction workers. During long cable laying operations, workers are prone to lapses in attention and fatigue. Any operational errors can easily lead to uncontrolled cable dragging and other construction accidents, threatening the personal safety of workers and the safety of equipment and property. Furthermore, the wooden boards used in existing braking systems tend to age and crack after repeated use. If these problems are not detected and replaced in time, a broken board can directly cause brake failure, leading to serious on-site safety accidents.

[0005] Although some solutions for independent braking devices have been proposed in the industry, they all require large-scale modifications to the cable laying frame. This results in a significant increase in the size and weight of the modified cable laying frame, which not only makes transportation and on-site setup inconvenient, but also further increases the complexity and cost of construction. It cannot meet the diverse needs of construction of high-voltage power cables of different specifications, making it difficult to achieve large-scale promotion and application in the industry.

[0006] In summary, the braking methods and related improvement schemes currently used in all-iron disc brake systems all have many problems that urgently need to be solved. Developing a braking device that is universally applicable, highly safe, easy to operate, and can effectively protect the all-iron disc brake system has become an urgent need in the field of power cable construction. Utility Model Content

[0007] Therefore, the technical problem to be solved by this utility model is to overcome the fact that the brake of the all-iron disc in the prior art is manually braked by passing a wooden board, which is difficult to achieve a stable and effective braking effect and poses safety hazards. Although some independent braking device solutions have been proposed in the industry, they all require large-scale modification of the cable laying frame. This makes the modified cable laying frame significantly larger and heavier, which is not only inconvenient for transportation and on-site layout, but also further increases the complexity and cost of construction. It cannot meet the diverse needs of construction of high-voltage power cables of different specifications, and it is difficult to achieve large-scale promotion and application in the industry.

[0008] To solve the above-mentioned technical problems, this utility model provides a cable reel with an autonomous braking device, comprising, The cable reel includes a tube body, a cylinder body, and side plates. The tube body is coaxially disposed in the inner hole of the cylinder body, and multiple support members are perpendicularly connected between the side of the tube body and the inner wall of the cylinder body near both ends of the tube body. The side plates are annular and are sleeved on both ends of the cylinder body and fixedly connected to it. A braking module includes a housing, a drive source, brake pads, and a controller. The housing is connected to the support member. The drive source and the controller are respectively disposed inside the housing. The output end of the drive source extends outside the housing and is perpendicular to the axis of the tube. The output end of the drive source is connected to the brake pads.

[0009] In one embodiment of this utility model, the braking module includes a storage battery, which is installed in the housing and is connected to the drive source and the controller respectively.

[0010] In one embodiment of this utility model, a mounting groove is provided on the top of the box, and a solar panel is connected in the mounting groove. The solar panel is connected to the battery.

[0018] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a cable reel and cable laying device with an autonomous braking mechanism. The braking module is directly integrated into the support of the cable reel, eliminating the need for large-scale modifications to the existing cable laying frame structure.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] Example 1, refer to Figures 1-5 As shown, this utility model discloses a cable reel with an autonomous braking device, comprising: Cable reel 1 includes a tube body 11, a cylinder body 12 and a side plate 13. The tube body 11 is coaxially arranged in the inner hole of the cylinder body 12, and a plurality of support members 14 are vertically connected between the side of the tube body 11 and the inner wall of the cylinder body 12 near both ends of the tube body 11. The side plate 13 is annular and is sleeved on both ends of the cylinder body 12 and fixedly connected to it. Braking module 2 includes housing 21, drive source 22, brake pads 23 and controller 24. Housing 21 is connected to support member. Drive source 22 and controller 24 are respectively installed in housing 21. The output end of drive source 22 extends outside housing 21 and is perpendicular to the axis of tube 11. Brake pads 23 are connected to the output end of drive source 22.

[0023] This utility model discloses a cable reel with an autonomous braking device. The braking module 2 is directly integrated into the support member 14 of the cable reel 1, eliminating the need for large-scale modifications to the existing cable laying frame structure. This maintains the original size and portability of the cable laying device and is suitable for various specifications of cable reels 1 and cable laying scenarios. The braking module 2 precisely controls the brake pads 23 to apply pressure to the support shaft of the cable laying frame through the drive source 22. The braking force is uniform and controllable, completely avoiding the instability of manual braking and many defects of wooden board friction. This effectively prevents the cable from being dragged out of control. The controllable and non-destructive braking method avoids wear on the anti-corrosion layer of the cable reel 1 surface due to braking operations, extending the service life of the cable reel 1. At the same time, through the controller 24, pressure sensor, wireless communication module, etc., precise control of braking force, real-time status monitoring, remote operation, and fault alarm can be realized, greatly improving the automation level and operational safety of the operation, and reducing the dependence on manpower and operational risks.

[0024] Specifically, the tube 11 is rotatably connected to the support shaft of the external cable reel. Multiple support members 14 are vertically connected between the side of the tube 11 and the inner wall of the cylinder 12, near both ends of the tube 11. These support members 14 act like a sturdy bridge, tightly connecting the tube 11 and the cylinder 12, not only enhancing the overall structural strength of the cable reel 1 but also evenly distributing the pressure borne by the cable reel 1 during cable loading and rotation. The side plates 13 are annular, fitted onto both ends of the cylinder 12 and fixedly connected thereto (they can be connected using a welding machine). The presence of the side plates 13 not only serves to block and protect the cable, preventing it from slipping off the sides of the cable reel 1 during cable laying, but also further enhances the structural stability of the cable reel 1.

[0025] Multiple brake modules 2 can be symmetrically arranged. During the rotation of the cable reel 1, the output end of the drive source 22 extends, causing the brake pads 23 to contact and rub against the side of the support shaft of the cable reel, thereby achieving the braking function. To achieve precise control of the braking process, the brake module 2 can also be used in conjunction with pressure sensors and speed sensors. The sensors collect braking pressure data and cable reel 1 rotation speed data in real time and transmit the data to the controller 24. The controller 24 adjusts the output thrust of the drive source 22 according to preset parameters to ensure that the cable reel 1 performs cable reeling operations at a set uniform rotation speed.

[0026] Specifically, the drive source 22 consists of a small hydraulic module and a high-power small motor (which can be an electro-hydraulic actuator, etc.). Under normal operating conditions, it can achieve a maximum output thrust of 700N. Under emergency braking conditions, the system can instantly output a thrust of 900N, ensuring that braking can be achieved quickly in case of emergencies and avoiding accidents.

[0027] Reference Figures 3-5As shown, the brake module 2 further includes a battery 25, which is installed inside a housing and connected to the drive source 22 and the controller 24. Specifically, the brake module 2 is powered by a small, high-capacity battery 25 and is equipped with a high-performance solar panel 26 for real-time charging in good weather, thereby enabling the brake module 2 to operate for a longer period of time.

[0028] Furthermore, a mounting slot is provided on the top of the housing 21, in which a solar panel 26 is connected, and the solar panel 26 is connected to a battery 25. Specifically, the solar panel 26 converts solar energy into electrical energy and stores it in the battery 25, realizing self-powered replenishment and effectively improving the equipment's endurance, especially suitable for outdoor construction scenarios without external power supply.

[0029] Furthermore, the brake module 2 includes a display screen 27, which is connected to the controller 24. Specifically, the front of the brake module 2 is also equipped with a display screen 27 to provide real-time feedback on the remaining battery power of the device. It also features a buzzer alarm that automatically sounds when the battery level drops below a warning threshold, allowing on-site personnel to better control the construction schedule and prevent accidents. Even better, a status indicator light can be installed on the outside of the housing 21. When the battery 25's power is low, the corresponding indicator light illuminates, allowing operators to detect the low level promptly.

[0030] Furthermore, a pressure sensor is installed between the output end of the drive source 22 and the brake pad 23, and the pressure sensor is connected to the controller 24. During cable laying operations, the controller 24 can control the drive source 22 to move according to a preset program or a received remote command, pushing the brake pad 23 against the support shaft of the cable laying frame to generate friction braking force, thereby controlling the rotation speed of the cable reel 1 and achieving autonomous braking (the output can be adjusted according to different needs by setting a gear control knob). The pressure sensor provides real-time feedback on the braking force, and the controller 24 performs closed-loop control accordingly to ensure that the braking force remains stable within the set range. Remote monitoring and intelligent management can be achieved through a wireless communication module. Preferably, an emergency brake button can be installed on the housing, so that in case of an emergency, the operator can press the emergency brake button to brake and avoid accidents.

[0031] Furthermore, the brake pad 23 has an arc-shaped plate structure, with the center of the arched side of the brake pad 23 perpendicularly connected to the output end of the drive source 22. The arc-shaped plate structure can increase the contact area between the brake pad 23 and the support shaft of the cable reel, as well as the uniformity of force distribution, which is beneficial for the uniform rotation of the cable reel 1.

[0032] Furthermore, it includes a wireless communication module, which is disposed in the housing 21 and is connected to the controller 24 for wireless data communication with the remote monitoring terminal.

[0033] Furthermore, a speed sensor for detecting the rotational speed of the cable reel is included. This speed sensor can employ a non-contact measurement principle, such as a Hall effect sensor or a photoelectric sensor. The operator can set a target cable-laying speed in the controller 24 via remote commands or a preset program. If the actual speed exceeds the target speed, the controller 24 will increase the output of the drive source 22 (or increase the target value of the pressure sensor), causing the brake pads 23 to press harder, increasing the braking force and reducing the rotational speed. If the actual speed is lower than the target speed, the controller 24 will decrease the output of the drive source 22, reducing the braking force and making it easier for the cable reel 1 to rotate under cable traction. Specifically, the speed sensor can be fixedly mounted on an external stationary component that does not rotate with the cable reel 1, such as the support shaft of the cable-laying frame or a specially fixed bracket nearby. Correspondingly, several sensing markers are evenly arranged along the circumference of the outer surface of one side plate 13 of the cable reel 1. The speed sensor and the controller 24 establish a signal connection via wireless data transmission or a slip ring electrical connection. The controller 24 can accurately calculate the real-time rotational speed of the cable reel 1 by calculating the number of pulses received per unit time.

[0034] Furthermore, the brake module 2 also includes a buzzer alarm, which is connected to the controller 24. The buzzer alarm is electrically connected to the controller 24. When the controller 24 detects faults such as abnormal braking pressure, low battery power of the battery 25, or the speed of the cable reel 1 exceeding the set range, it will control the buzzer alarm to issue an alarm signal, promptly reminding the operator to handle the situation and reducing the risks caused by the fault.

[0035] Furthermore, a heat dissipation vent is provided on one side of the housing 21, corresponding to the position of the drive source 22. A cooling fan is installed on the heat dissipation vent to prevent overheating and damage to the drive unit under continuous high load operation. Specifically, a heat dissipation device is provided in the housing 21, which is not limited to air-cooled heat dissipation equipment.

[0036] Furthermore, the back of the housing 21 is provided with a fastening clamp 28 for connecting with the support member 14, which can meet the fastening requirements of the brake module 2 under extreme working conditions.

[0037] In embodiment two, this utility model also discloses a cable reel, including a cable reel with an autonomous braking device as in embodiment one.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
