Embodiment Construction

[0021] Now in conjunction with accompanying drawing, the present invention will be further described.

[0022] Such as Figure 1 ~ Figure 3 As shown, the winch device includes a motor assembly, a brake assembly, a transmission shaft 18, a speed reduction mechanism, a clutch mechanism, and a winch 13. The motor assembly is composed of a motor bracket 2 connected to a motor 1, and the brake assembly is composed of a driving seat 3 and a torsion spring lower seat. 4. The brake torsion spring 5, the torsion spring upper seat 6, the brake fork 7, the positioning sleeve 8, and the brake sleeve 9 are composed of the drive seat and the motor, the brake fork and the transmission shaft are plugged and slidably matched, and the specific structure of the brake assembly The connection can refer to the patent No. 201220335401.9, and the patent name is "winch braking device", so it will not be described in detail. Speed ​​reducing mechanism is made of gear bracket 19, reduction box 21, firs...

Abstract

The invention relates to a winch device and an on-off method thereof. The winch device and the on-off method thereof aim at solving the technical problems that winch use is affected due to the fact that space arrangement of an on-off mechanism is not rational in existing similar products. The winch device comprises a dynamic assembly, a transmission shaft, a reducing mechanism, an on-off mechanism, and a winding cylinder. The winch device is characterized in that one end of the transmission shaft is matched with an output end of the dynamic assembly in a sliding and plugging mode, a reset spring is arranged between the one end of the transmission shaft and the dynamic assembly, the on-off mechanism comprises a pushing assembly which abuts against the other end of the transmission shaft and can push the transmission shaft to slide axially, and a transmission part which is rotatably located on the transmission shaft and can slide axially along with the transmission shaft to be connected with the reducing mechanism and the winding cylinder in a transmission mode. The transmission part is matched with axial slide of the transmission shaft, and therefore disconnection or connection of transmission between the winding cylinder and the reducing mechanism is achieved. The winch device and the on-off method thereof has the advantages of being simple in structure, small in size, convenient to install and use, suitable for winches or structural improvement of similar products.

Description

technical field [0001] The invention relates to a winch, which is a winch device. Background technique [0002] A winch is a device that can be used for traction, such as a car winch, and can be used for self-rescue and rescue in harsh environments. [0003] The existing winch device such as the invention patent application number 201010184492.6 published in the Chinese patent literature, the application publication date was September 29, 2010, and the name is "an electric winch", which includes a motor, a transmission rod, a drum, a speed reduction mechanism, and a left bracket. , the motor is fixed on the left bracket, the left end of the transmission rod is connected to the motor, the right end of the transmission rod is connected to the reduction mechanism, the reduction mechanism is also connected to the drum, the reduction mechanism is a planetary gear reducer, and the planetary gear reducer contains at least two sets of planetary gears The components, the clutch mech...
