Problems solved by technology

When in use, the motor drives the reel to move through the reducer, and the steel wire on the reel is released or retracted to complete the lowering and raising of the heavy object. When the heavy object needs to stop at a certain height, the brake electromagnet acts and passes through the connecting rod. The mechanism drives the friction caliper 15 to clamp the brake wheel to stop the reel from rotating, but it is found in actual use that after the structure is used for a long time, due to the high motor speed, the friction between the brake wheel and the friction caliper is severe, and the friction caliper It needs to be replaced regularly to ensure work safety, and it also affects the work safety of the motor

Embodiment Construction

[0016] Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not restrictive, and the protection scope of the present invention cannot be limited by the following examples.

[0017] A durable hoisting device such as Figure 1~4 Shown, comprise base 1, speed reducer 2, brake wheel 14, motor 12 and reel 11, one side of base installs speed reducer, the input end of this speed reducer connects motor through brake wheel, innovation of the present invention That is: the output end of the speed reducer is connected to the rotating shaft 17 of the reel installed in the shaft sleeve 8 through a clutch 3, a brake disc 6 is respectively installed at both ends of the reel, and a brake disc 6 is installed on each brake disc. Pneumatic calipers 4, the two pneumatic calipers are connected to an air pump 9 through a solenoid valve 7.

[0018] In the present embodiment, the clutch includes a fixed disc 23, a movable disc 2...

Abstract

The invention relates to a durable winching lifting device. The output end of a reduction box is connected with the rotary shaft of a winding drum through a clutch; a brake disc is mounted at each of two ends of the winding drum; a pair of pneumatic calipers is mounted on each brake disc in a counterpoint manner; and the two pairs of pneumatic calipers are connected with an air pump through an electromagnetic valve. According to the invention, brake wheels only need to brake for a while, so that friction loss is reduced; a motor is not in a driven braking state on the long-term basis; and in addition, due to the function of the pneumatic calipers, the winding drum is high in braking speed, the height of a weight is accurate, the overall work is safer, and the efficiency is higher.

Description

technical field [0001] The invention belongs to the structural field of hoisting devices, in particular to a durable hoisting hoisting device. Background technique [0002] There are many types of lifting equipment, among which the gantry crane and hoist are more common. The hoist is a device that drives the reel and winds the rope to complete the traction work by manpower or mechanical power. It can lift vertically and pull heavy objects horizontally or obliquely. . The structure of the hoist is: including base 1, reducer 2, reel 11, motor 12, brake wheel 14 and brake electromagnet 16, a reducer is installed on one side of the base, and the input end of the reducer passes through the brake wheel Connect the motor output shaft 13, and the output end of the reducer is connected to the reel through the rotating shaft 17. When in use, the motor drives the reel to move through the reducer, and the steel wire on the reel is released or retracted to complete the lowering and rai...
