Problems solved by technology

The general hoist structure, because the cable is too heavy, needs to be driven by the motor to drive the cable to be retracted and released. Therefore, when the motor is damaged or locked, the cable cannot be operated normally, and some hoist structures are designed to prevent The cable is too heavy to cause damage to the motor and fall, and some additional locking mechanisms will be set to lock the motor and the cable
But with this structure, if there is a problem with the motor, if it is in the state of unwinding, the cable will not be able to be retracted, which will cause a lot of trouble

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Hoist of the present invention, as Figure 1-6 As shown, it includes a housing 1 and a motor 2 located in the housing 1. The output shaft 2 of the motor rotates, and the output shaft of the motor 2 is covered with a sprocket (not shown in the figure), and the motor 2 drives the sprocket Rotate, a chain (not shown) is sleeved on the sprocket, and the other end of the chain is sleeved on a transmission gear 3, and then the motor 2 can drive the transmission gear 3 to rotate, and the outer surface of the transmission gear 3 is provided with a The tooth shape of the chain matches.

[0023] The transmission gear 3 is sleeved on the rotating shaft 4 and can rotate outside the rotating shaft 4. One end of the rotating shaft 4 protrudes from the outer side of the housing 1, and the rotating shaft 4 is fixedly sleeved on one end of the housing ...

Abstract

The invention provides a winch comprising a drive gear connected with the output shaft of a motor and driven by the motor to rotate. The winch is characterized in that the drive gear is sleeved onto a laterally arranged rotary shaft and is capable of rotating relative to the rotary shaft. One end of the rotary shaft is fixedly provided with a wire wheel. A sleeve is fixedly sleeved onto the rotary shaft and is positioned adjacent to the drive gear. A mating structure is arranged between the drive gear and the sleeve. Based on the mating structure, the drive gear drives the sleeve to rotate synchronously in two directions. Meanwhile, the sleeve is capable of rotating in one direction relative to the drive gear. In this way, not only the take-up operation and the pay-off operation of the wire wheel can be realized under the driving effect of the motor, but also the one-way take-up operation of the wire wheel is enabled even in the locked or outage condition of the motor. The winch is compact and rational in integral structure, and convenient to machine and use.

Description

technical field [0001] The invention relates to a winch. Background technique [0002] There are usually a variety of fishing equipment and various fishing machines on ocean-going fishing vessels, such as belt fishing machines, tuna fishing machines, and other equipment for purse seine fishing. These fishing machines and equipment are inevitably A winch structure is required, which is used to take up and pay off heavy cables. The general hoist structure, because the cable is too heavy, needs to be driven by the motor to drive the cable to be retracted and released. Therefore, when the motor is damaged or locked, the cable cannot be operated normally, and some hoist structures are designed to prevent The cable is too heavy to cause damage to the motor and fall, and some additional locking mechanisms are set to lock the motor and the cable. But with this structure, if there is a problem with the motor, if it is in the state of unwinding, the cable will not be able to be retr...
