Hydraulic winch It is usually used in engineering buildings, agriculture, forestry, mining, ports and other places, but their appearance is not the same. What are the differences between them, and are their basic working principles the same? actually windlass According to different forms, there are many classifications, and they all have different effects. Next, let's understand the hydraulic winch and its basic working principle.
Hydraulic winch is also called Hydraulic winch It is applied to all kinds of hoisting machinery and equipment. The prime mover drives the hydraulic oil pump to deliver the operating hydraulic oil to the actuator (hydraulic cylinder or Hydraulic motor )To make the mechanism act, the speed can be changed by controlling the liquid flow into the executive component. The advantage of hydraulic propulsion is that it has large transmission ratio, can achieve a wide range of stepless speed change, compact structure, relatively stable operation, convenient operation, and good overvoltage protection characteristics.
The basic working principle of the hydraulic winch is as follows: 1. In the lifting and starting stage, when the gate is raised and the drum is tightened, the star wheel cannot rotate. Driven by the center wheel, the star wheel rotates automatically, pushing the inner gear ring to rotate the drum, so as to improve the drilling equipment. When the load of the hydraulic winch mechanism increases, the instantaneous stage of the load from the static state to the relatively stable running speed is called the lifting start stage. When hoisting and starting, the inertia force direction is the same as the lifting load direction, which increases the tension resistance of the steel rope.
2. In the stage of hoisting and braking, when the holding brake brakes the drum machine, the drum machine and the internal gear are braked at the same time and do not rotate. At this time, the traveling star wheel rotates automatically and does revolution to brake the drilling equipment. The stage in which the hydraulic winch mechanism slows down from uniform motion braking to standstill is called lifting braking stage. The inertia force caused by the deceleration motion quality is in the opposite direction to the lifting load, so the tension resistance of the steel rope is reduced.
