the slow descending device in the prior art works, the planet wheel speed reducing mechanism in the main machine is driven to run through the slow descending rope and generate a friction effect with a friction block in a friction wheel hub, the user is guaranteed to safely and slowly descend to the ground, but the existing slow descending device is simple in structure and lacks of a take-up mechanism, so that the slow descending device cannot take up the line after being used, only a single escape person can be provided to descend, when more people are trapped in an accident, one slow descending device cannot be used for escape in sequence, a plurality of slow descending devices need to be prepared in advance for use, and the practicability of the slow descending device is greatly reduced.

Disclosure of Invention

According to the technical problems, the invention provides a slow descending device with a lifting control function, which is characterized by comprising a motor, an expansion shell, a left gear, a main shaft, a right gear, a main shell, a planet wheel assembly and a gear shell, wherein the gear shell is arranged at the top of the main shell, a through groove is formed at the top of the main shell, a main shaft is arranged in the through groove, the top of the main shaft passes through the through groove and extends to the inner part of the gear shell to be connected with a right gear, the bottom of the main shaft passes through the through groove and extends to the inner key of the main shell, and is connected with a planetary wheel assembly, a rope is arranged in the planetary wheel assembly, the left end of the top of the main shell is connected with an expansion shell, the top of the expansion shell is provided with a motor, a left gear is arranged in the expansion shell, the bottom of the motor is connected with a left gear through an output shaft, the bottom of the expansion shell is communicated with a gear shell, and the left gear is matched with the right gear for use.

The invention has the beneficial effects that:

the invention replaces the original brake structure of the brake disc by arranging the battery, the motor, the expansion shell, the pinion, the main shaft, the gearwheel and the gear shell, the gearwheel is driven to rotate by the rotation of the pinion to form a brake effect and can perform lifting movement, when an operator uses the escape device, the rope in the planetary wheel component is fixed at a high position, the main shell is fixed on the body of the operator, when the operator descends, the operator pulls the planetary wheel component to rotate by the rope by means of self gravity, the gearwheel is driven to rotate by the main shaft, so that the pinion meshed with the main gear is driven to rotate, the pinion is connected with the output shaft of the motor and generates damping by the magnetic induction of the motor, so that the rotating speed of the pinion is reduced, the transmission of the main shaft is reduced, the descending speed of the user is reduced, the user safely lands finally, and then the operator starts the motor to rotate reversely, the motor drives the pinion to rotate reversely, so that the gear wheel is driven to rotate reversely, at the moment, the transmission is realized through the planet wheel, and the main shell can be driven to ascend when being taken up due to the fact that the rope is fixed at a high position until the main shell is lifted to the rope fixing position, other personnel trapped at the high position can continue to use the device, and the lifesaving personnel can wear the device to perform auxiliary climbing and high-altitude rescue work due to the fact that the lifesaving device can ascend, so that the practicability of the device is greatly improved, multiple trapped personnel can be helped to perform slow descending in sequence through the design, and the practicability is greatly improved;

in addition, the portable lifting device is small in size and convenient to carry, can be used in other environments requiring the position of a user to rise, achieves the purpose of free lifting, greatly improves the practicability and the application range, and can be applied to various industries and various scenes.

Detailed Description

Example 1

The invention provides a slow descending device with a lifting control function, which is characterized by comprising a motor 2, an expansion shell 3, a left gear 4, a main shaft 5, a right gear 6, a main shell 7, a planet wheel assembly 8 and a gear shell 1, wherein the gear shell 1 is installed at the top of the main shell 7, a through groove is formed at the top of the main shell 7, this logical inslot is provided with main shaft 5, 5 tops of main shaft pass and lead to groove and extend to 1 internal key-type connection of gear housing and have right gear 6, 5 bottoms of main shaft pass and lead to groove and extend to 7 internal key-type connections of main casing and have planet wheel subassembly 8, from taking the rope in the planet wheel subassembly 8, the left end at 7 tops of main casing is connected with extension shell 3, motor 2 is installed at 3 tops of extension shell, the inside left gear 4 that is provided with of extension shell 3, there is left gear 4 motor 2 bottom through output shaft connection, 3 bottoms of extension shell communicate with gear housing 1, left gear 4 uses with the cooperation of right gear 6.

Example 2

When the invention is used, namely when an operator is used for escaping, a rope in the planetary wheel assembly 8 is fixed at a high position, the operator fixes the main shell 7 on the body, when the operator descends, the operator pulls the planetary wheel assembly 8 to rotate by the rope by means of self gravity, the main shaft 5 drives the right gear 6 to rotate, so as to drive the left gear 4 engaged with the right gear to rotate, because the teeth of the left gear 4 are connected with the output shaft of the motor 2, damping is generated under the magnetic induction of the motor 2, so that the rotating speed of the left gear 4 is reduced, further the transmission of the main shaft 5 is reduced, the descending speed of the operator is reduced, finally the operator safely falls to the ground, then the operator starts the motor 2 to rotate reversely, the motor 2 drives the left gear 4 to rotate reversely, so as to drive the right gear 6 to rotate reversely, at the moment, the transmission is carried out by the planetary wheel, because the rope is fixed at the high position, when the wire is taken up, the main shell 7 can be driven to rise until the main shell 7 rises to the rope fixing position, other people trapped at a high place can continue to use the device, and the lifesaving device can be worn by the lifesaving device to assist in climbing and rescue at a high place due to the fact that the lifesaving device can rise, and therefore practicability of the lifesaving device is greatly improved.
