Abstract
Description
Technical Field
[0001] This utility model belongs to the field of deceleration technology, specifically relating to an electric lift deceleration device. Background Technology
[0002] A descent device is a safety device widely used in high-altitude operations, fire rescue, and emergency escape. It primarily uses mechanical friction and clutch control to enable personnel or goods to descend vertically at a constant speed and safely from heights. Traditional descent devices are typically purely mechanical, possessing only a descent function and lacking the ability to perform both lifting and lowering operations, thus limiting their practical application. For example, in some construction sites or high-altitude work scenarios, users not only need to safely lower the device but may also need to raise personnel or equipment back to a higher position. In such cases, additional external power equipment, such as an electric drill, is often required to drive the descent device via a power input interface for lifting.
[0003] However, using an electric drill as an independent power source has obvious inconveniences: First, electric drills are large and operators need to carry them with them, increasing the burden of working at heights; second, the connection structure between the electric drill and the descent device is relatively simple, and the unstable connection can easily cause safety hazards; third, the power output of traditional electric drills cannot be precisely controlled, and the lifting speed and torque are difficult to adjust finely, resulting in problems such as impact and jamming.
[0004] Therefore, there is an urgent need for a compact, safe, reliable, and easy-to-operate integrated electric lifting and slow-descent device to solve the problems of inconvenient operation, poor safety, and redundant power devices in the existing technology. Utility Model Content
[0005] To address the aforementioned issues, this utility model provides an electric lift decelerator that is compact, safe, reliable, and easy to operate, thus resolving problems such as inconvenient operation, poor safety, and redundant power devices in existing technologies.

The power component includes a motor and a reducer connected to the output end of the motor. The output end of the reducer is connected to the power input interface.
[0008] In some embodiments, the descent device body includes an assembly plate, a pulley assembly on one side of the assembly plate, a handle and a gear set on the other side of the assembly plate, a gear cover on the gear set, and the gear cover is mounted on the assembly plate.
[0009] In some embodiments, the power assembly further includes a first housing and a second housing mounted on one side of the first housing. The first housing is used to protect the gearbox, and the second housing is used to protect the motor. The first housing is mounted on the gear cover.
[0010] In some embodiments, the gear cover has screw holes, the first housing is mounted on the gear cover by screws, the first housing has screw holes, and the second housing is mounted on the first housing by screws.

[0012] In some embodiments, a slot is provided on one side of the first housing and the second housing, and a motor control board is provided on one side of the slot. The power supply is plugged into the slot and forms an electrical connection with the motor control board.
[0013] In some implementations, a wireless control module is provided on the motor control board.
[0014] In some embodiments, the bottom of the first and second housings are provided with a switch button for controlling the motor's on / off state.

[0024] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0025] like Figure 1-4 As shown, this utility model discloses an electric lift descent device, including a descent device body 1 and a power component 2. The descent device body 1 enables the slow descent of goods or personnel from a height, while the power component 2 provides the driving force required for ascent, realizing an integrated lifting function.
[0026] The descent device body 1 includes an assembly plate 11, which is a flat mounting base plate used to install and support the various functional components of the descent device body. A pulley assembly 12 is installed on one side of the assembly plate 11. The pulley assembly 12 achieves vertical lifting and lowering movement through a rope. The rope can be arranged around the pulley to improve mechanical efficiency.
[0027] On the other side of the assembly plate 11, there is a handle 13, a gear set 14, and a gear cover 15. The handle 13 is used for manual operation or handling of the device. The gear set 14 is connected to the power input interface 3 and is used to transmit the power output from the motor to the rope traction structure inside the descent device through deceleration, thereby realizing the upward movement of the descent device. The gear set 14 is covered by a gear cover 15 to enclose and protect the internal gear structure and prevent dust and moisture from entering.
[0028] The power assembly 2 includes a motor 21, a reducer 22, a first housing 23, and a second housing 24. Both the first housing 23 and the second housing 24, including the gear cover 15, are made of aviation-grade aluminum alloy 7075. The motor 21 is a DC brushless motor with a rated power of 250W, a rated voltage of 24V, and a rated speed of 3000RPM. It is powered by a power supply 4 and drives the output shaft to rotate. In this embodiment, the power supply is a lithium battery pack with a rated voltage of 24V and a capacity of 10Ah, which can operate continuously for approximately 30 minutes. The output shaft of the motor 21 is connected to the input end of the reducer 22. The reducer 22 is a planetary gear reducer with a reduction ratio of 30:1 and a rated output torque of 12Nm. It is used to convert the high-speed, low-torque output of the motor into a low-speed, high-torque output to meet the lifting requirements of the decelerator. The output end of the reducer 22 is connected to the power input interface 3 via a shaft connection structure to achieve torque transmission.
[0029] To ensure the safe operation of the motor and reducer, the reducer 22 is housed within the first housing 23, and the motor 21 is housed within the second housing 24. The first housing 23 is fixed to the gear cover 15 with screws 25, providing a stable connection structure. The second housing 24 is mounted on the first housing 23 with screws 25, facilitating maintenance and disassembly.
[0030] A power supply 4 is located on one side of the power assembly 2. The power supply 4 is a lithium battery module or a portable power supply unit, which is connected via a slot 5. The slot 5 is located on the side of the first housing 23 and the second housing 24, and is connected to the motor control board 6 to achieve electrical communication. The motor control board 6 is also equipped with a wireless control module for receiving wireless signals from a remote control or mobile APP to control the start, stop, speed adjustment, and other functions of the motor 21. In other embodiments, the motor control board 6 has a MOS driver, overcurrent protection, overvoltage protection, and overtemperature protection; supports 2.4GHz wireless communication or Bluetooth BLE communication; and has soft-start function.
[0031] To facilitate manual on-site control, a switch button 7 is also provided at the bottom of the first housing 23 or the second housing 24 for manually turning the motor 21 on or off.
[0032] When using this electric lift and descent device, the operator simply needs to attach the device to a high anchor point, thread the rope through the pulley system, and connect it to the load. To ascend, the operator starts the motor; power is transmitted to the descent device via the reduction mechanism, causing the rope to rewind and achieve ascent. To descend, the motor can be turned off or the power disconnected; the friction / clutch mechanism within the descent device itself allows for a smooth, controllable descent. The lifting and lowering operations can be controlled wirelessly or via mechanical buttons, making it simple to operate and safe to use.
[0033] In summary, this device has improved upon the traditional hand-held electric drill-based lifting mechanism by integrating power, which not only simplifies the operation process but also improves safety and practicality, making it suitable for scenarios such as high-altitude operations, fire rescue, and construction.
