Research method for transformation of transmission and brake of single beam crane
Posted: Dec 19th, '24, 21:33
The crane transmission device is a key component of engineering machinery vehicles, which changes the transmission ratio of the engine crankshaft through a single-beam transmission. Double-beam cranes mainly include lifting mechanisms, operating mechanisms, luffing mechanisms, slewing mechanisms and metal structures. The lifting mechanism is the basic working mechanism of the crane, mostly composed of a hanging system and a winch, and there are also hydraulic systems that lift heavy objects. European cranes have been formed in the industry in recent years to distinguish them from the so-called domestic, Soviet (Soviet) and traditional cranes in the past.
Mainly include: bridge cranes, gantry cranes, cantilever cranes, flexible beam cranes, explosion-proof cranes and other industrial cranes. For jib-type cranes, the rated lifting capacity of bridge cranes varies with the amplitude, and its lifting characteristic index is characterized by the lifting torque. The value marked on the sign is the maximum lifting capacity. To meet the requirements of driving wheel traction and speed under different driving conditions such as starting, accelerating, driving and overcoming various road obstacles. In order to ensure the efficient and energy-saving operation of construction machinery, the operating conditions and environment of construction machinery are very complex and changeable. During the operation, the engine load changes greatly, the machine operating speed changes frequently, and fast movement requires constant adjustment of the machine's gears.
The brake device is an important part of ensuring the safe and normal operation of the crane. In the lifting operation, the brake device is used to prevent the hanging objects or boom from falling, and to prevent the turntable or crane from sliding under the action of wind or slope force; the single-beam crane can also grab heavy objects for operation according to the needs of the work; in special cases, the movement speed can be adjusted by controlling the balance of power and gravity.
When the meshing sleeve is engaged with the gear ring of the auxiliary transmission, the planetary gear shaft, the output shaft, the planetary gear ring of the crane and the input shaft gear of the auxiliary transmission are fixed at the lower gear and rotate synchronously, so that the auxiliary transmission enters (direct gear), and the five gear ratios of the main transmission are equal to the five smaller transmission ratios of the combined transmission. Since the two transmission ratios are very close, the smaller transmission ratio is omitted to form a 9-speed transmission.
The brake system device of the single-beam crane is mainly divided into two types: brakes and stoppers. The stopper can only make the shaft rotate freely in one direction, and cannot absorb kinetic energy, and can only support and keep objects stationary. The working mechanism of the crane should be equipped with brakes in most cases. Only in the following basic conditions can the brake be installed: 1. The mechanism is driven by a cylinder that makes a linear lifting motion, and the locking oil circuit can stop the mechanism. 2. The manual mode operation service mechanism of the bridge crane is not affected by wind or slope force.
