Anti-slip safe brake

Abstract

The invention relates to a brake device capable of safety protection in the technical field of engineering machinery, in particular to an anti-slip safe brake applied to an operating mechanism of a window cleaning machine. The anti-slip safe brake comprises a power-driven push rod, a bearing shaft, a locating baffle sleeve, a bearing wheel, a locating jack screw, an eccentric wheel, a thrust spring, a horizontal guide wheel, a frame body, a friction brake block and disk springs, wherein the power-driven push rod is fixed on the frame body; a power-driven push rod head props against the bearing shaft; the locating baffle sleeve is sleeved on the bearing shaft; the bearing wheel is connected to the locating baffle sleeve; the locating jack screw is fixed on the frame body; the head of the locating jack screw props against a gap of the eccentric wheel; the thrust spring is sleeved on the friction brake block; one end of the thrust spring jacks up the frame body and the other end of the thrust spring jacks up the eccentric wheel; the horizontal guide wheel is fixed on the friction brake block; the friction brake block is connected to the frame body; and the disk springs are connected in grooves at the two ends of the frame body and are fixed by eyelet bolts. The anti-slip safe brake has reliable self-locking performance and high sensitivity and can be used for effectively solving the problem of braking of the window cleaning machine during running.

Description

technical field [0001] The invention relates to a brake device for safety protection in the technical field of construction machinery, in particular to a power-off anti-skid brake applied to an operating mechanism of a window cleaning machine. Background technique [0002] With the rapid development of China's economy in recent years, the promotion of its construction machinery has gradually changed from completely relying on foreign imports in the early stage to independent research and development, and the indicators of many products have reached the advanced level of foreign countries, and the performance of some engineering equipment has even reached the advanced level. Exceeding the top level of foreign technology. But after all, China has not really experienced the industrial revolution in Western countries. Although some have formed a series of construction machinery products with their own characteristics, most of them still refer to the early technology of the Sovi...

Problems solved by technology

But after all, China has not really experienced the industrial revolution in Western countries. Although some have formed a series of construction machinery products with their own characteristics, most of them still refer to the early technology of the Soviet Union, especially in crane products. Without its own innovation and research and development, affected by the development of China's construction industry, the development of window cleaning machines on the world stage has delayed a big step

At present, the most commonly used method for the parking brake of the window cleaning machine operating mechanism is to use the rail clamp. Although the rail clamp can prevent the equipment from sliding relative to the track, its operability is cumbersome and its reliability is low. The effective resistance generated is small, and it is easy to slip when the applied force is large. The biggest disadvantage is that it will only be tightened manually when the machine is shut down.

Such as ratchet pawl stoppers, electromagnet brakes, hydraulic push rod brakes, etc., as brakes, these products can only stop the rotating motion, but cannot be applied to the operation of various trolleys
