Problems solved by technology

Although some have designed working brakes and speed-regulating brakes so that the winches can brake and speed-regulate in time, they often cannot brake in time when encountering a sudden power failure. This will not only affect the service life of the mechanical system, but may also cause broken ropes. and other accidents, and the winch that cannot brake will lose control under the load, which may cause a major safety accident

Embodiment Construction

[0011] As one of the best embodiments of a coaxial double-drum self-locking winch of the present invention, see the attached figure 1 , which includes a base on which a drive motor 1, a shaft coupling, a transmission 3, a reel device 2 and other parts are arranged.

[0012] The driving motor 1 is a power source, and it can adopt a variable frequency motor, or even an air motor or a hydraulic motor. The coupling is connected to the output end of the drive motor 1. The coupling adopts an elastic pin coupling, which has good vibration reduction and vibration absorption, and can compensate for the deflection and misalignment of the two shafts when installed; Another feature is that after the fatigue damage of the elastic pin, the shaft of the transmission and the shaft of the motor can still be connected together to ensure safe and reliable transmission. A speed regulating brake is arranged outside the shaft coupling according to the existing method, and the speed regulating belt...

Abstract

A coaxial double-winding-drum self-locking winch comprises a base, wherein a drive motor, a coupler, a speed changer and a winding-drum device are arranged on the base. The coaxial double-winding-drum self-locking winch is characterized in that the winding-drum device comprises a pair of winding drums arranged on the same spindle, the speed changer is a turbine worm speed changer and located between the two winding drums, a turbine key is connected onto the spindle and rotates with the spindle synchronously, and a worm and a turbine are matched and connected with the drive motor through the coupler. A brake is arranged on the spindle on the outer sides of the winding drums and comprises a brake shoe and an electric hydraulic thruster, wherein the brake shoe is held on a brake wheel at the outer end of the spindle in a surrounding mode, and the electric hydraulic thruster controls opening and closing of the brake shoe through a lever. The coaxial double-winding-drum self-locking winch has the advantages that security coefficients are improved by adopting double coaxial winding drums, inverted self locking is achieved through the worm and the turbine, outage and braking are achieved through the additional brake, and the security coefficients are improved obviously.

Description

technical field [0001] The invention belongs to the field of construction engineering vehicles, in particular to a coaxial double-drum self-locking winch. Background technique [0002] The power winch is a kind of hoisting equipment that performs the function of lifting objects by manipulating the retraction and release of steel cables. It is widely used in engineering construction, relocation of heavy objects, or self-rescue and mutual rescue in case of accidents. The traditional power winch uses a motor to drive a single drum, and the drum can be reversed. Although some have designed working brakes and speed-regulating brakes so that the winches can brake and speed-regulate in time, they often cannot brake in time when encountering a sudden power failure. This will not only affect the service life of the mechanical system, but may also cause broken ropes. and other accidents, and the winch that cannot brake will lose control under the load, which may cause a larger safety...
