Example Embodiment

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see figure 1 , the embodiment of the present invention provides a hopper hydraulic control flow path, which is mainly applied to the hydraulic control of the scrap hopper, to control the opening or closing of the claw of the scrap hopper, which includes an oil inlet pipe 1, an oil return pipe 2 and a hydraulic cylinder 3. The oil pipe 1 provides high-pressure oil to the hydraulic cylinder 3 to control the rise of the hydraulic cylinder 3, and then the h...

Abstract

The invention provides a hydraulic control oil way of a hopper. The hydraulic control oil way comprises an oil inlet pipe, an oil return pipe and a hydraulic cylinder and further comprises a first plug-in throttling valve, a second plug-in throttling valve and a first solenoid valve for switching and controlling the first plug-in throttling valve and the second plug-in throttling valve to be opened. An oil inlet of the first plug-in throttling valve is connected with the oil inlet pipe, and an oil outlet of the second plug-in throttling valve is connected with the oil return pipe. An oil outlet of the first plug-in throttling valve and an oil inlet of the second plug-in throttling valve are both connected with the hydraulic cylinder. The invention further provides a hopper gripper. The hopper gripper comprises the control oil way. According to the hydraulic control oil way of the hopper and the hopper gripper, the first solenoid valve switches and controls the first plug-in throttlingvalve and the second plug-in throttling valve to be opened, the opening and closing action and speed of the hopper gripper can be controlled, the pipeline is simple and reliable, and high popularization and use value and good economical efficiency and universality are achieved.

Description

technical field [0001] The invention relates to an electric furnace steelmaking hydraulic pressure, in particular to a hopper hydraulic control oil circuit and a hopper gripper. Background technique [0002] Due to the short steelmaking process and the use of scrap steel as the main raw material, electric furnace steelmaking has greater advantages than converter steelmaking in terms of cost saving and environmental protection. The scrap hopper is an important equipment for electric furnace steelmaking. It is used to load scrap steel and add scrap steel to the furnace. However, the current hydraulic oil circuit control flow path is far away, and the opening and closing of the hopper claws are slow. Contents of the invention [0003] The purpose of the present invention is to provide a hopper hydraulic control oil circuit, which is intended to be used to solve the existing scrap steel hopper. [0004] The present invention is achieved like this: [0005] An embodiment of t...
