Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical lubrication equipment, and in particular relates to an intelligent automatic lubrication system for a screw ship unloader. Background Art

[0002] The so-called lubrication system refers to the general term for a series of grease supply, grease discharge and its auxiliary devices that supply lubricants to the lubrication parts. At present, there are basically two lubrication modes for automatic lubrication systems: one is the dry oil pump multi-point lubrication method, which branches out from one pump to multiple points to the parts that need lubrication. It has several defects: first, the lubrication points are limited, and the market can only do more than 20 points; second, all lubricating oil pipelines are caused by multi-point lubrication pumps, which are messy, easy to leak oil, and difficult to maintain. The other is to use a pneumatic lubricating oil pump + multi-point distributor single and double line mode, first from the oil pump through the main line, and then use the tee to reach different distributors, and then the distributor lubricates each lubrication point. The biggest problem with this mode is that if one of the lubrication points of the distributor is blocked, the other lubrication points on the distributor cannot be supplied with oil, which will cause multiple lubrication points to lack oil, causing major mechanical failures. In addition, during the oil delivery process, the oil supply device itself lacks a corresponding voltage stabilizing structure, resulting in large fluctuations in lubricating oil distribution.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a differential reduction box external circulation forced lubrication system for a differential ship unloader [03115239.2], in which the reducer is a differential reduction box, and the ball valve P4 is connected from the oil outlet of the differential reduction box through a pipeline, and the ball valve P4 is connected to the thermistor, and then to the electric air pump, and is divided into two paths through the electric air pump, one of which returns to the oil inlet pipe of the electric air pump through the overflow valve D, and the other is connected to the pressure switch P2, and then connected to the oil filter P3, and leads to the pressure switch P1 to reach the pressure measuring point, and is divided into two paths at the pressure measuring point, one of which is connected to the solenoid valve DA to the reduction box oil inlet pipeline, and the other enters the air-cooled heat exchanger after passing through the solenoid valve DA2, and the heat exchanger outlet is connected to the bimetallic thermometer P9, connected to the solenoid valve DA1 through the pressure measuring point, and returns to the reduction box oil inlet.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, an intelligent automatic lubrication system for a screw ship unloader includes an electric lubrication pump 1 for storing and providing pressure for lubricating oil. The electric lubrication pump 1 is connected in parallel with a plurality of oil distribution tanks 3 through a main pipeline 2. The number of oil distribution tanks 3 can be expanded arbitrarily according to actual needs to meet the distribution needs of a large number of lubrication points. The oil distribution tanks 3 are connected to the lubrication points through a plurality of auxiliary pipelines 4 respectively. At the same time, the main pipeline 2 and the auxiliary pipeline 4 are adjustable, so that the coverage of the lubrication system is not limited by the spatial distance. The electric lubrication pump 1 has a built-in multi-stage oil supply component 5 to limit the oil delivery amount and oil delivery rate. A voltage stabilizing component 6 is provided at the oil outlet of the electric lubrication pump 1 to maintain the internal oil pressure of the main pipeline 2 stable.

[0024] Specifically, the electric lubrication pump 1 is installed on the ship unloader, and specifically includes a cylindrical oil supply tank 11, a pressure oil tank 12 is arranged at the lower end of the oil supply tank 11, an oil delivery channel 13 is arranged between the oil supply tank 11 and the pressure oil tank 12 for supplying lubricating oil to the pressure oil tank 12, the top of the oil supply tank 11 is closed by a sealing cover 14 and a lock 15 is arranged in between to facilitate the replenishment of lubricating oil and maintenance of the inside of the electric lubrication pump 1, and a drive component is installed inside the pressure oil tank 12.

[0025] In depth, similar to conventional drive structures, the drive assembly in the present application includes an oil pump 16 installed inside the oil pressure tank 12. Pressure sensors are respectively installed at the inlet and outlet of the oil pump 16 to monitor pressure fluctuations and maintain its stability through negative feedback. The oil pump 16 is connected to a drive motor 17, and the drive motor 17 is a servo motor.

[0026] Furthermore, unlike the existing single cavity structure, the multi-stage oil supply assembly 5 includes partition plates 51 arranged inside the oil supply tank 11 and arranged one by one up and down, and oil supply cavities 52 are left between adjacent partition plates 51 to store the lubricating oil layer by layer, and an opening and closing assembly for controlling the connection state of the oil supply cavity 52 is installed on the partition plate 51 to ensure its normal falling flow. When the ship unloader is in motion, multiple relatively independent oil supply cavities 52 can effectively reduce the fluctuation caused by the inertia of the internal lubricating oil.

[0027] Furthermore, in order to control the flow and falling rate of the lubricating oil, the opening and closing assembly includes an opening and closing shaft 53 installed inside the oil supply box 11 and extending in the vertical direction, the opening and closing shaft 53 is connected to an opening and closing plate 54 corresponding to the upper end of the partition plate 51, the partition plate 51 and the opening and closing plate 54 are provided with overlapping opening and closing holes 55, and a switching assembly for driving the opening and closing shaft 53 to rotate is installed between the opening and closing shaft 53 and the sealing cover 14. When the opening and closing shaft 53 drives the opening and closing plate 54 to rotate, the opening and closing holes 55 switch between overlapping and staggered states, and the number of opening and closing holes 55 connected between the partition plate 51 and the opening and closing plate 54 is also adjusted accordingly, thereby controlling the oil flow rate and flow rate of the lubricating oil in the upper and lower oil supply chambers 52.

[0028] In addition, the switching assembly includes a switching motor 56 installed on the upper end of the sealing cover 14, the output end of the switching motor 56 faces downward and a transmission block 57 is installed between the upper end of the opening and closing shaft 53, and there are mutually meshing transmission teeth 58 between the transmission blocks 57. The switching motor 56 provides a switching torque, and a stepping motor is selected to limit the rotation angle of the opening and closing shaft 53, and the opening and closing plate 54 also rotates a fixed angle accordingly.

[0029] At the same time, the number of the connected opening and closing holes 55 on the partition plate 51 and the opening and closing plate 54 decreases from top to bottom. When the electric lubrication pump 1 is started, the channels between the opening and closing holes 55 are in an open state, and the lubricating oil also falls layer by layer. In the process of consuming the lubricating oil, the lubricating oil in the oil supply tank 11 is consumed layer by layer.

[0030] It can be seen that the pressure-stabilizing component 6 includes a pressure-stabilizing valve 61 installed at the oil outlet of the electric lubrication pump 1, and a pressure relief pipe 62 is installed between the pressure-stabilizing valve 61 and the electric lubrication pump 1. The pressure sensor monitors the internal oil pressure of the main pipeline 2 and the auxiliary pipeline 4 in real time, so that the pressure-stabilizing valve 61 can adjust the lubricating oil delivery volume in time, and the excess lubricating oil can be discharged by the pressure relief pipe 62 when necessary.

[0031] Obviously, in order to ensure the intelligence of the lubrication system, the electric lubrication pump 1 is connected to a control cabinet 7, the control cabinet 7 is connected to an electric heating element 71, and the control cabinet 7 has a built-in Ethernet communication unit 72 and a 4G wireless transmission unit 73 to realize real-time monitoring and remote control of the lubrication system.

[0032] Preferably, the outer side of the electric lubrication pump 1 is coated with a corrosion-resistant layer, and at the same time, an obvious mark is provided on the outside of the electric lubrication pump 1 to facilitate the determination of its position relative to the ship unloader, and to facilitate subsequent routine maintenance and repair.

[0033] To sum up, the principle of this embodiment is that the electric lubrication pump 1 provides lubricating oil, which is distributed to each auxiliary pipeline 4 by the oil distribution tank 3 to achieve full coverage of the lubrication points, wherein the electric lubrication pump 1 is internally provided with a multi-stage oil supply component 5 and a voltage stabilizing component 6, which realizes flow and quantity limiting of the lubricating oil during the oil supply stage to ensure the oil distribution stability of each lubrication point.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
