Problems solved by technology

The brake of the winch mostly adopts a manual brake, and a lever amplifying mechanism is generally used to brake the outer circle of the wheel hub. The brake handle is long and has a large structure, so it is inconvenient to use it when the structure is limited.

Embodiment

[0014] This device is used to drive the mooring winch of the lifting balloon with special equipment. In order to prevent the brake failure of the driving components (such as electric motor or hydraulic motor) from causing the balloon to slide under the action of buoyancy and cause accidents, safety protection measures must be considered. A manual friction brake is added as an emergency measure. At this time, the braking device faces a more severe situation than the wheel brake, because not only the inertial force must be overcome, but also the pulling force exerted by the buoyancy of the balloon to the winch through the cable all the time.

[0015] figure 1 It is the three-dimensional structure diagram of the device. The whole brake device is integrated with the flange sleeve 2 as the installation matrix. The parts seen in the figure include handwheel 1, flange sleeve 2, flange sleeve 3, screw shaft 6. Guide rod 8, friction plate 9, brake wedge 10, nut 11, copper sleeve 12. T...

Abstract

The invention discloses a friction braking device with a wedge block force magnifying structure. The device comprises a handwheel 1, a flange sleeve 2, a flange plate sleeve 3, an end cover 4, a bearing 5, a screw rod shaft 6, a nut sleeve 7, a guide rod 8, a friction plate9, a braking wedge block 10, a nut 11 and a copper sleeve 12. The device has the characteristics of compact structure and high supporting stiffness through the embedded structure that the friction braking device is integrated into the flange sleeve, and also has the characteristics of large braking force and labor conservation in operation through a screw rod nut and wedge block two-stage force magnifying structure. The device is applied to winch driving wheels.

Description

technical field [0001] The invention relates to a friction brake device, in particular to a friction brake device with a wedge booster structure for a drive wheel of a winch. Background technique [0002] Friction brake devices are often used for braking wheels or other wheel structures. The wheel brakes of automobiles usually use drum brakes or disc brakes. The invention patent "hydraulic operated partial disc friction brake" (ZL88103080) proposed a A friction brake that uses hydraulic oil to push a piston to generate a braking force. At present, this braking method is widely used in the wheel braking of cars, that is, the so-called disc brake. The invention patent "drum brake" (ZL200680012563.6) is applied to the brake drum by a pair of brake blocks through a hydraulic or electric drive device, and the wheel is braked by using the friction between the brake block and the brake drum. [0003] Since the wheels of the car have stopped driving (the accelerator is released) wh...
