Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic control, in particular to a funnel hydraulic control system. Background Technique

[0002] When bulk cargo is handled at the river port, eliminating spillage, dust, etc. is the top priority of environmental protection work. At the same time, the original operation method is that after the crane grab takes goods from the cabin, it guides the materials through a straight-through funnel into the truck carriage. However, there are still deficiencies in the existing straight-through funnel material guiding, specifically: the existing funnel has no storage function, which affects the operation efficiency. When discharging materials, the flow rate and velocity cannot be controlled, and spillage and dust generation are very likely to occur. Due to the height influence, the crane driver will have a visual error. Once the truck below the funnel is not accurately positioned, the falling materials will hit above the driver's cab, posing a safety hazard. Content of the Utility Model

[0020] For the embodiment, please refer to Figures 1-4 , the present invention provides a technical solution:

[0021] A funnel hydraulic control system includes a hydraulic oil tank 1 and a hopper body 11. A filtering mechanism 2 is arranged inside the hydraulic oil tank 1. The outer wall of the filtering mechanism 2 is connected to a gear pump 3 through a pipeline. A motor 4 is installed on the back of the gear pump 3. The oil outlet of the gear pump 3 is connected to an electromagnetic overflow valve 5 through a pipeline. The bottom of the electromagnetic overflow valve 5 is fixedly connected to a valve seat 6. The top of the valve seat 6 is fixedly connected to a three-position four-way electromagnetic reversing valve 7 near the electromagnetic overflow valve 5. The three-position four-way electromagnetic reversing valve 7 is connected to a rotary oil cylinder 8 through a pipeline. The outer wall of the output shaft of the rotary oil cylinder 8 is fixedly connected to a driving gear 9. The outer wall of the hopper flap of the hopper body 11 is fixedly connected to a transmission gear 10. A monitoring camera 12 is installed on the outer wall of the hopper body 11. The bottom of the hydraulic oil tank 1 is installed with a base 13. A remote control console 14 is installed on the outer wall of the base 13. A wireless transmitter 15 is installed on the outer wall of the base 13.

[0022] Among them, there are two groups of three-position four-way electromagnetic reversing valves 7, rotary oil cylinders 8 and driving gears 9. The valve seat 6 is made of aluminum alloy. The wireless transmitter 15 and the monitoring camera 12 are both connected to the remote control console 14 through a wireless data network. A pressure gauge is installed on the outer wall of the pipeline between the gear pump 3 and the electromagnetic overflow valve 5. The connection mode between the driving gear 9 and the transmission gear 10 is meshing connection. The three-position four-way electromagnetic reversing valve 7 and the electromagnetic overflow valve 5 are connected through an oil delivery pipeline.

[0023] In this embodiment, refer to Figure 2 and Figure 3, as a preferred solution of the present utility model, the filtering mechanism 2 includes a filter box 201 fixedly connected to the oil outlet on the outer wall of the hydraulic oil tank 1. The outer wall of the filter box 201 is threadedly connected with a box cover 202. A sealing gasket 203 is fixedly connected to the outer wall of the box cover 202 and inside the filter box 201. An installation frame 204 is slidably connected inside the filter box 201. A filter screen 205 is fixedly connected inside the installation frame 204. Sealing rings 206 are fixedly connected to the outer walls of the installation frame 204. A pushing spring 207 is fixedly connected inside the filter box 201 near the installation frame 204. An electromagnet 208 is installed inside the filter box 201 at a position far from the pushing spring 207. A storage battery 209 is installed inside the filter box 201. An electronic button 210 is installed on the outer wall of the filter box 201.

[0024] Among them, both the filter box 201 and the box cover 202 are made of aluminum alloy. The filter box 201 is designed in a circular structure. Both the sealing gasket 203 and the sealing rings 206 are made of silica gel. Multiple groups of the pushing spring 207, the installation frame 204, the electromagnet 208, and the filter screen 205 are provided. The installation frame 204 is made of stainless steel. The connection modes of the electromagnet 208, the storage battery 209, and the electronic button 210 are all electrical connections. The installation frame 204 is designed in a rectangular structure. The shape of the filter screen 205 is adapted to the shape of the installation frame 204. When too much debris adheres to the filter screen 205, unscrew the box cover 202 and press the electronic button 210. The electronic button 210 turns off the electromagnet 208, and the electromagnet 208 no longer attracts the installation frame 204. The pushing spring 207 will push the installation frame 204 upward, and the installation frame 204 exits the filter box 201. After cleaning the filter screen 205 in the installation frame 204 and putting it back into the filter box 201, press the electronic button 210 again. The electronic button 210 will activate the electromagnet 208, and the electromagnet 208 will attract the installation frame 204. Then install the box cover 202 on the filter box 201 to complete the cleaning and replacement of the filter screen 205.

[0025] When the funnel hydraulic control system designed with this solution is in operation, the monitoring camera 12 will transmit the image captured below the funnel body 11 to the remote console 14 through the wireless transmitter 15. The staff will judge whether the transport vehicle below the funnel body 11 is parked directly below the funnel body 11 according to the captured image. When the position of the transport vehicle is appropriate, the motor 4 is started. The motor 4 drives the gear pump 3 to operate. The gear pump 3 sends the hydraulic oil in the hydraulic oil tank 1 into the electromagnetic overflow valve 5 through the pipeline. When the hydraulic oil flows through the filter box 201, the sundries inside it will be filtered out by the filter net 205. The filtered hydraulic oil will flow into the electromagnetic overflow valve 5 and enter the rotary oil cylinder 8 through the electromagnetic overflow valve 5 and the three-position four-way electromagnetic directional valve 7. The hydraulic oil entering the rotary oil cylinder 8 will drive the output shaft of the rotary oil cylinder 8 to rotate. The output shaft of the rotary oil cylinder 8 drives the transmission gear 10 to rotate through the driving gear 9. The transmission gear 10 will drive the valve flap of the funnel body 11 to rotate, and the funnel body 11 is opened. The material in the funnel body 11 will fall into the transport vehicle. After the material transportation is completed, the gear pump 3 sends the hydraulic oil in the rotary oil cylinder 8 back to the hydraulic oil tank 1 through the pipeline. The rotary oil cylinder 8 drives the transmission gear 10 to rotate in the reverse direction through the driving gear 9. The transmission gear 10 rotating in the reverse direction will drive the funnel body 11 to close.

[0026] When there are too many sundries attached to the filter net 205, unscrew the box cover 202 and press the electronic button 210. The electronic button 210 turns off the electromagnet 208. The electromagnet 208 no longer attracts the mounting frame 204. The push spring 207 will push the mounting frame 204 to move upward. The mounting frame 204 exits the filter box 201. After cleaning the filter net 205 in the mounting frame 204 and then putting it back into the filter box 201, press the electronic button 210 again. The electronic button 210 will start the electromagnet 208. The electromagnet 208 will attract the mounting frame 204, and then install the box cover 202 on the filter box 201 to complete the cleaning and replacement of the filter net 205.
