Description

Technical Field

[0001] The invention belongs to the technical field of gate hoists, and in particular relates to a novel hydraulic gate hoist. Background Art

[0002] A hydraulic gate hoist is generally composed of a hydraulic system and a hydraulic cylinder. Under the control of the hydraulic system, the piston body in the hydraulic cylinder reciprocates along the axial direction of the hydraulic cylinder, thereby driving the connecting rod gate connected to the piston to make linear motion to achieve the purpose of opening and closing the orifice. A hydraulic gate hoist is a device that uses the pressure energy of liquid to transfer energy to control the opening and closing of the gate. It is widely used in water conservancy and hydropower projects, urban water supply and drainage systems, industrial production lines and other fields. Especially in water conservancy and hydropower projects, hydraulic gate hoists are key equipment for controlling the opening and closing of dams, gates and sluices. They play a vital role in water resource management, flood control and power generation. The working principle of the hydraulic gate hoist is based on hydraulic transmission. When the hydraulic pump is started, it converts mechanical energy into the pressure energy of hydraulic oil, and converts it through pipelines and hydraulic valve groups. The pressure oil is delivered to the hydraulic cylinder. In the hydraulic cylinder, the pressure oil pushes the piston to move, which in turn drives the connecting rod and gate actuators connected to the piston to make linear motion to open or close the gate. This process is not only efficient, but also has smooth transmission and almost no noise, which provides a strong guarantee for the quiet operation of water conservancy projects. The hydraulic gate hoist is usually composed of a hydraulic pump station, a hydraulic cylinder, a hydraulic valve group, a hydraulic pipeline and an electrical detection and control device. Among them, the hydraulic pump station serves as a power source, converting mechanical energy into hydraulic energy; the hydraulic cylinder is an actuator, converting hydraulic energy into mechanical energy to drive the gate movement; the hydraulic valve group controls the flow, direction and pressure of the hydraulic oil, thereby achieving precise control of the opening and closing of the gate; the electrical detection and control device is used to monitor the operating status of the hydraulic gate hoist and realize remote control and automated operation.

[0003] In actual applications of hydraulic gate hoists, the power pack is fixedly installed on the gate hoist cylinder, and the position of the power pack cannot be adjusted. When the power pack needs maintenance, it needs to be removed together with the cylinder. This integrated fixing method makes it more troublesome to independently inspect, disassemble and replace the power pack and the cylinder. There is also the problem of increased cost when the whole is scrapped. In addition, the hydraulic cylinder is fixed in the installation area, which is not convenient for flexible adjustment later. This makes it difficult to install objects at different inclination angles and heights. Therefore, a new type of hydraulic gate hoist is needed to solve the problems existing in the prior art.
