Novel hoisting mechanism for crane boom

Abstract

The invention discloses a novel hoisting mechanism for a crane boom. The novel hoisting mechanism comprises an automobile chassis, wherein a fixed seat is arranged on the automobile chassis, and a lower boom is arranged on the upper part of the fixed seat; a crane boom body I is rotationally arranged at the end part of the lower boom, a crane boom body II is rotationally arranged at one end part of the crane boom body I, a telescopic boom is arranged at the end part of the crane boom body II, and a working bucket is arranged at the end part of the telescopic boom; and lifting structures are arranged between the lower boom and the bottom of the crane boom body I and between the upper part of the crane boom body I and the bottom of the crane boom body II, the two lifting structures compriseupper auxiliary booms, lower auxiliary booms, transmission lead screws and gear motors, and control face boards are arranged on the automobile chassis and in the working bucket. According to the novelhoisting mechanism for the crane boom, the motors are used as power, and hydraulic oil is not used, so that energy conservation and environmental protection are achieved; the structure is simple, repairing and maintenance are easy, cost is low, double self-locking is safer, and light weight of the device can be realized; and in addition, motor drive is adopted, slow start and slow stop can be achieved easily through control of the control face boards, and therefore the cargo boom can ascend and descend more stably.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a novel lifting arm lifting mechanism. Background technique [0002] At present, lifting and lifting equipment are generally equipped with a boom, such as cranes, truck-mounted cranes, aerial work vehicles, etc. In the current technology, the lifting of the boom is all through the jacking of the hydraulic cylinder to lift the boom. The advantage of the hydraulic cylinder is that it has a large force, but it needs the hydraulic system to provide hydraulic power. The hydraulic system needs hydraulic pumps, hydraulic valves, and hydraulic oil. There are a lot of components, the cost is high, the technology is complicated, and the maintenance is not easy; and a large amount of hydraulic oil is used, which is easy to leak and pollute the environment; an engine or an electric motor is used, which is transmitted to the hydraulic pump through the power take-off, and the hydraul...

The advantage of the hydraulic cylinder is that it has a large force, but it needs the hydraulic system to provide hydraulic power. The hydraulic system needs hydraulic pumps, hydraulic valves, and hydraulic oil. There are a lot of components, the cost is high, the technology is complicated, and the maintenance is not easy; and a large amount of hydraulic oil is used, which is easy to leak and pollute the environment; an engine or an electric motor is used, which is transmitted to the hydraulic pump through the power take-off, and the hydraulic pump converts energy into hydraulic pressure. Power, hydraulic power is converted into mechanical power, multiple energy conversions, large losses
