Crane Truck
Crane refers to a machine that uses a hook or other object-taking device to hang heavy objects and perform cyclic operations such as lifting and moving in space. There are many types of cranes. Common names such as "crane", "tower crane", "overhead crane" and "truss crane" refer to one or several types of cranes. An automobile crane is a kind of crane installed on an ordinary automobile chassis or a special automobile chassis. Its driving cab and lifting control room are separately set. The advantages of this crane are good mobility and rapid transfer. The lifting mechanism is the basic working mechanism of the crane. Most of them are composed of a hanging system and a winch. There are also hydraulic systems that lift heavy objects. The luffing mechanism is only equipped on boom-type cranes. The amplitude decreases when the boom is raised and increases when it is bent down. It is divided into balanced luffing and unbalanced luffing. The slewing mechanism is used to rotate the boom. It is composed of a drive device and a slewing support structure. The chassis performance of the automobile crane is equivalent to that of a truck with the same total vehicle weight.
It meets the technical requirements of road vehicles and can therefore pass unimpeded on various types of roads. Transport cranes are generally equipped with two operating rooms for getting on and off the vehicle. The outriggers must be extended to maintain stability during operation. The metal structure is the skeleton of the crane. The main load-bearing parts such as the bridge, boom, and gantry can be box-shaped structures, truss structures, or web structures. Some can also use steel as support beams.
Working Principle Diagram Of Hydraulic Lifting System Of Dump Truck
1. Normal driving state of the car:
At this time, the power take-off control valve is in the right position, the power take-off is not connected, the gear pump does not work, and there is no oil flow in the system. At this time, the lifting air control valve and the lifting valve are both in the middle stop position, and the lifting oil cylinder is in the lowest position;
2. Power take-off is connected, and the lifting oil pump is working:
When we want to lift the truck bed, we should first combine the power take-off with the lifting oil pump. At this time, the power take-off control valve is energized, the valve core moves to the left, the power take-off control air circuit is connected, and the power take-off is connected to the lifting oil pump shaft. Let the engine power pass through the gearbox to the power take-off and the lifting oil pump, let the oil pump rotate at high speed, and generate high-pressure oil. Since the lifting valve is in the middle position at this time, these high-pressure oils return to the oil tank through the oil channel inside the lifting valve and are filtered by the return oil filter;
3. Lifting state:
When lifting the truck bed, we need to turn the air control valve to the left to the lifting position, connect the system air pressure and the air control valve lifting channel, and the system air The pressure flows through the air control valve through the limit valve and enters the lifting valve from the lifting interface, acts on the cylinder piston, pushes the piston to the left, and drives the valve core to move to the left, connects the oil pump interface with the lifting cylinder interface, and the high-pressure oil enters the cylinder and lifts the cylinder; if the lifting pressure is too large, the bypass overflow valve will open to prevent the pressure from continuing to rise and causing damage to the gear pump and pipeline;
4. Descending state:
When the bucket needs to be lowered, we need to turn the air control valve to the right to the descending position, connect the system air pressure and the air control valve descending channel, and the system air pressure enters the lifting valve from the descending interface through the air control valve, acts on the piston, pushes the piston to the right, and drives the valve core to move to the right, connects the lifting cylinder interface with the return oil interface, and the high-pressure oil in the cylinder flows back to the tank and is filtered by the return oil filter;
5. Stop state:
Whether it is lifting or descending, we can stop the movement of the cylinder at any time. As long as we turn the air control valve to the middle stop position, the compressed air acting on the piston in the lifting valve will be discharged from the exhaust port of the air control valve, and then the valve core returns to the middle position under the action of the spring force, cutting off the connection between the cylinder interface and other interfaces, and the high-pressure oil in the cylinder stops flowing in or out, and the cylinder piston is in a stationary state, which is the so-called middle stop state;
6. Limit state:
When the lifting cylinder rises to the set lifting height, it will touch the limit valve, causing the valve core of the limit valve to move to the left, cutting off the air path between the system air pressure and the lifting valve, and causing the compressed air acting on the piston to be discharged from the exhaust port of the limit valve, so that the valve core will return to the middle position under the action of the spring force, cutting off the connection between the lifting cylinder interface and the oil pump interface, and the cylinder stops rising.
