Background
The hydraulic cylinder is a hydraulic actuator which converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is in direct proportion to the effective area of the piston and the pressure difference between the two sides of the effective area; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffering device and an exhaust device. The damping device and the exhaust device are determined according to specific application occasions, and other devices are necessary. According to the structural form of the common hydraulic cylinder, the hydraulic cylinder can be divided into four types, namely a piston type, a plunger type, a telescopic type and a swing type. In a hydraulic system, a mechanism with certain mass is driven by using a hydraulic cylinder, when the hydraulic cylinder moves to the stroke end point, the hydraulic cylinder has larger kinetic energy, if the hydraulic cylinder does not perform speed reduction treatment, a piston of the hydraulic cylinder and a cylinder cover are mechanically collided, impact and noise are generated, and the hydraulic cylinder is destructive. To mitigate and prevent this hazard, a reduction device may be provided in the hydraulic circuit or a damping device may be provided in the cylinder. The single-piston rod hydraulic cylinder is only provided with a piston rod at one end. A single piston hydraulic cylinder is shown. The oil ports A and B at the inlet and outlet of the two ends can be communicated with pressure oil or return oil to realize bidirectional movement, so the double-acting cylinder is also called as a double-acting cylinder. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The lifting mechanism is also called a lifting platform, and is lifting equipment for lifting people or goods to a certain height. The lifting mechanism is also called a lifting platform, and is lifting equipment for lifting people or goods to a certain height. When vertical conveying is performed in logistics systems such as factories and automatic warehouses, various plane conveying devices are often arranged on the lifting platform and serve as connecting devices of conveying lines with different heights. The hydraulic lifting platform is generally driven by hydraulic pressure, so the hydraulic lifting platform is called as a hydraulic lifting platform. The device is widely applied to high-altitude installation, maintenance and other operations besides being used for conveying goods with different heights.
The lifting mechanism disclosed in the Chinese utility model patent application publication No. CN207669988U comprises a first upright and a second upright, the first upright is provided with a first cylinder, the second upright is provided with a second cylinder, a beam is arranged between the first cylinder and the second cylinder, one end of the beam is fixedly connected with the push rod of the first cylinder, the other end of the beam is fixedly connected with the push rod of the second cylinder, although the utility model has the effects of simple structure and convenient use, the utility model uses two hydraulic cylinders to lift the device, and the beam is fixedly connected between the push rods of the two hydraulic cylinders, the beam is easy to break when the lifting is carried out because the hydraulic cylinders are lifted asynchronously, so that the lifting device is seriously damaged, and the utility model only depends on the hydraulic cylinders to bear weight when the lifting is not carried out, and has no device for assisting the hydraulic cylinders to bear weight, the hydraulic cylinder is easily damaged too early, which is not beneficial to protecting the hydraulic cylinder.
