Description

Technical Field

[0001] This utility model relates to the field of subway electromechanical cable winding and unwinding technology, and in particular to a subway electromechanical cable winding and unwinding device. Background Technology

[0002] Metro electromechanical cables are a key component in urban rail transit systems that provide power transmission, signal control, and communication functions for electromechanical equipment.

[0003] With the rapid development of urban rail transit, the demand for cable laying and recycling in subway electromechanical engineering is becoming increasingly frequent. As a key construction equipment, the efficiency, stability and safety of cable laying and recycling devices directly affect the project progress and personnel safety.

[0004] Traditional cable reeling and unloading devices mostly employ manual or semi-mechanized structures, using simple rollers for movement. However, they lack effective fixing methods during operation, making the devices prone to displacement due to cable tension or uneven ground. External tools (such as pads) are needed for fixation, resulting in cumbersome operation and poor stability. This is especially problematic in the narrow environment of subway tunnels. Existing equipment often relies on manual cranking or a single motor drive, lacking a rapid braking mechanism in emergency stops or power outages, easily leading to safety hazards such as cable loosening and rebound. During cable reeling and unloading, traditional guide wheels are mostly fixed structures, unable to dynamically adjust their lateral and longitudinal positions according to the cable's direction. This results in chaotic cable arrangement, increased wear, and even jamming and breakage. Cable reels come in various sizes, while the mounting shaft structure of traditional devices is fixed. Changing cable reels requires repeated disassembly and adjustment, which is time-consuming and labor-intensive, making it difficult to meet the rapid switching requirements of various scenarios in subway engineering. Therefore, designing a subway electromechanical cable reeling and unloading device is essential to solve this problem. Utility Model Content

[0005] This invention addresses the problems of existing cable winding and unwinding devices, which mostly employ manual or semi-mechanized structures and rely on simple rollers for movement. However, these devices lack effective fixing methods during operation, making them prone to displacement due to cable tension or uneven ground. External tools (such as pads) are needed for fixation, resulting in cumbersome operation and poor stability. This is especially problematic in the narrow environment of subway tunnels. Existing equipment often relies on manual cranking or a single motor drive, lacking a rapid braking mechanism in emergency stops or power outages, easily leading to safety hazards such as cable loosening and rebound. During cable winding and unwinding, traditional guide wheels are mostly fixed structures, unable to dynamically adjust their lateral and longitudinal positions according to the cable's direction, resulting in chaotic cable arrangement, increased wear, and even jamming and breakage. Cable reels come in various sizes, while traditional devices have fixed mounting shaft structures, requiring repeated disassembly and adjustment when replacing cable reels, which is time-consuming and labor-intensive, failing to meet the technical requirements of rapid switching in various scenarios in subway engineering. Therefore, this invention provides a subway electromechanical cable winding and unwinding device.

[0034] This subway electromechanical cable retraction device features a linkage design between moving and fixed components. The electrically controlled telescopic rod adapts to uneven ground, and the increased contact area via a support plate prevents displacement or overturning. It is particularly suitable for the narrow, slippery, and complex environments of subway tunnels, solving the cumbersome and safety hazards of traditional equipment that relies on manual padding. During rotation, in conjunction with the braking component, millisecond-level braking is achieved through frictional contact between the brake pad and the rotating disc when the drive stops, preventing cable detachment or inertial rebound and significantly improving safety in emergency situations. The guide component... The system uses horizontal and vertical guide rollers to achieve horizontal lateral correction and vertical longitudinal positioning of the cable. Combined with the adjustable limit rod of the limiting component, it dynamically constrains the cable laying and winding path, preventing cable wear, jamming, or tangled mess. It is especially suitable for the precise laying of large-diameter, heavy cables. The installation component uses an adjustable installation rotating rod, which can be adapted to cable reels of different inner diameters by adjusting bolts. A strip-shaped limit block is used to lock the cable reel end face bidirectionally, achieving "one-click" assembly and disassembly. This significantly shortens the time for changing cable reels, improves the continuity of multi-specification cable operations, and has a relatively simple structure and is easy to use.

[0073] The base 1 is provided with a support housing 11, the support housing 11 is provided with a battery 12, and the support housing 11 is provided with a controller 13.

[0074] The supporting housing 11 on the base 1 is embedded in the central area of ​​the base 1, with dimensions of 600mm×400mm×200mm. The internal battery 12 is a 48V / 100Ah lithium iron phosphate battery pack. The bottom is equipped with a heat dissipation grille and a waterproof interface. The controller can be an STM32H743VIT6, an STMicroelectronics ARM microcontroller. The controller 13 integrates an STM32 main control chip and receives status signals from the electric telescopic rod 32, the rotary motor 61, and the electric lifting rod 81 via the CAN bus to realize command transmission.

[0075] First, insert the mounting rotating rod 71 into the center hole of the cable reel. Then, according to the size of the cable reel, install the mounting housing 72 onto the mounting rotating rod 71 to restrict the position of the cable reel. The strip-shaped limiting block 74 is located in the inner groove of the cable reel. The connecting plates 73 at both ends are aligned with the first connecting block 62 and the second connecting block 66 and are fixedly connected with high-strength bolts to complete the installation. The device is manually pushed by pushing the handle 4. When operating in narrow areas, the 360° turning function of the moving wheel 22 is used to move slowly in an "S" shaped path. Then, the controller 13 controls the electric telescopic rod 32 to automatically press down the support fixing plate 33 to the ground. The four corners of the bottom of the device are completely fixed. If the ground is uneven and the contact force on one side is insufficient, the controller 13 can be used to fine-tune each electric telescopic rod 32 individually. Then, the cable passes through the transverse guide wheel 931 and through the first longitudinal guide wheel 942 and the second longitudinal guide wheel 944. According to the cable diameter, the limiting housing 1 is adjusted by adjusting the housing 103 and the adjusting rod 104. The opening width is 06, allowing the cable to pass through the limiting shell 106. During cable laying, the controller 13 sets the laying speed, the rotary motor 61 rotates counterclockwise, and the cable is smoothly led out through the guide assembly 9. The operator holds the cable end and lays it along the tunnel direction, observing in real time whether the guide assembly deviates. During cable reeling, the controller 13 controls the motor to rotate clockwise, and the cable enters the guide assembly 9 through the limiting assembly 10, and then winds onto the cable reel. The position of the cable reel can be adjusted to prevent the cable from being wound in the same position during reeling. When an emergency stop is required, the controller 13 controls the rotary motor 61 to cut off the power, and the electric lifting rod 81 lifts the brake pad 84 within 50ms to press the first rotating disc 63 and the second rotating disc 67, thereby performing an emergency stop. When unloading the cable reel, the drive assembly 6 is stopped to perform an emergency stop. The braking assembly 8 automatically locks the first rotating disc 63 and the second rotating disc 67, loosens the bolts on the connecting plates 73 at both ends of the mounting rotating rod 71, and finally pulls out the mounting rotating rod 71 to complete the removal.

[0076] 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 scope of protection of this invention.
