[0003] At present, the commonly used oil temperature and oil level display devices for coal mining machines are mainly long cursors and round cursors. The long cursor 7 or the round cursor is usually installed in the traction part of the coal mining machine (see Figure 3 ), when the inclination angle of the coal mining machine working face is too large, affected by factors such as mining conditions and coal mining machine structure, the long cursor and the circular cursor cannot fully display the oil temperature and oil level conditions under different working conditions, that is, under large-angle working conditions, the oil level of the lubricating oil in the oil tank presents a large angle, and the oil level is very likely to be greater than the display range at the long cursor or the circular cursor, resulting in the oil level cannot be obtained intuitively, and the cursor loses the oil level display function. Therefore, it is difficult for the long cursor or the circular cursor to display the oil temperature and oil level of the coal mining machine in various working conditions, so that the staff cannot clearly obtain the oil temperature and oil level conditions of the gear box, which in turn affects the judgment of the working status of the coal mining machine.

[0022] like Figure 1 , Figure 2 As shown in the figure, they are schematic diagrams of different structures of the oil temperature and oil level display device of the utility model for coal mining machine, such as Figure 3 The figure is a schematic diagram of the structure of the oil temperature and oil level display device of the coal mining machine installed on the traction part of the coal mining machine. Figure 1-Figure 3 It can be seen that the oil temperature and oil level display device of the coal mining machine of the utility model includes: a horizontal cursor 1 having a first display structure for displaying the oil temperature and oil level of the coal mining machine; a vertical cursor 2 arranged vertically with the horizontal cursor and having a second display structure for displaying the oil temperature and oil level of the coal mining machine; a connecting structure 6 for fixedly connecting one end of the horizontal cursor to the upper end of the vertical cursor and allowing lubricating oil to flow between the two; and a quick-connect structure 4 arranged at the lower end of the vertical cursor for quickly connecting it to the gear box of the coal mining machine.

[0023] Specifically, the coal mining machine oil temperature and oil level display device of the utility model includes a horizontal cursor and a vertical cursor, both of which are rectangular, and the two cursors are detachably connected together through a connecting structure, so that any one cursor or two vertically arranged cursors can be selected for use according to different work needs.

[0024] Among them, the first display structure on the horizontal cursor and the second display structure on the vertical cursor can adopt the same or different structure of the oil temperature and oil level display structure 5, and the oil temperature and oil level display structure can adopt any one or more of an integral transparent hose, a combination of multiple oil temperature and oil level gauges, a combination of a transparent hose and an oil temperature and oil level gauge, an electronic display, etc. During assembly, the oil temperature and oil level display structure is respectively embedded in the interior of the horizontal cursor 1 and the vertical cursor 2 through a hollow bolt 51 to prevent the oil temperature and oil level display structure from being collided and squeezed when the coal mining machine is working. The hollow bolt can allow the oil to flow into the corresponding oil temperature and oil level display structure 5 through the internal cavity of the horizontal cursor 1 and the vertical cursor 2, effectively ensuring that the display structure accurately displays the oil temperature and oil level in the gear box of the coal mining machine. The structure of the oil temperature and oil level display structure being respectively embedded in the interior of the horizontal cursor 1 and the vertical cursor 2 through the hollow bolt 51 can refer to the prior art and will not be described in detail here.

[0025] Threaded holes are respectively set at both ends of the horizontal cursor, and threaded holes are respectively set above and below one end. The lower threaded hole is used for threaded connection with the connecting structure, and the upper threaded hole is connected to the screw plug 12 through a thread. The threaded hole at the other end of the horizontal cursor is used for threaded connection with the vent plug 11.

[0026] like Figure 2 As shown, the connection structure adopted by the utility model includes: a connection body whose two ends are respectively connected to the horizontal cursor and the vertical cursor by threads; a sealing ring sleeved outside the connection body for sealing the connection between the horizontal cursor and the vertical cursor. In addition, it also includes: a threaded hole opened at one end of the horizontal cursor and used for threading connection with the upper end of the connection body; a threaded hole opened at the upper end of the vertical cursor and used for threading connection with the lower end of the connection body.

[0027] Among them, the connecting body is a cylinder with external threads at both ends, and a through hole is opened in the center of the connecting body for connecting the inner cavity of the horizontal cursor and the inner cavity of the vertical cursor. The through hole can be connected with the inner cavity of the horizontal cursor, the inner cavity of the first display structure on the horizontal cursor, the inner cavity of the vertical cursor, and the inner cavity of the second display structure on the vertical cursor, so that the lubricating oil in the coal mining machine gear box can flow in the channel formed by the inner cavity of the horizontal cursor, the connecting body, and the vertical cursor.

[0028] Since the horizontal cursor, the connecting body and the vertical cursor are respectively connected by threaded structures, the direction of the horizontal cursor relative to the vertical cursor can be freely determined within a range of 360° with the central axis of the vertical cursor as the center.

[0029] The lower part of the connecting body is threadedly connected to the upper end of the vertical cursor, and the lower end of the vertical cursor is connected to a quick-connect structure 4 for quickly connecting it to the gear box of the coal mining machine. Figure 2 As shown, the quick-connect structure of the utility model includes: a connector for detachable connection with the lower end of the vertical cursor, which is a square or circular connector with a through hole in the center, which is a through hole or a threaded hole; a hose fixedly connected to the connector at one end and detachably connected to the gear box of the coal mining machine at the other end, such as a threaded connection or a flange or bolt connection; a threaded hole opened at the lower end of the vertical cursor and connected to its inner cavity; a connector bolt for passing through the through hole of the connector and threadedly connected to the threaded hole at the lower end of the vertical cursor, which is a hollow bolt with a side hole on the side wall so that it can be connected to the inner cavity of the hose, so that the lubricating oil transported by the hose is input into the inner cavity of the vertical cursor through the hollow bolt.

[0030] The horizontal cursor 1 and the vertical cursor 2 of the utility model can be used in combination through the connecting structure 6, and can also be used separately.

[0031] When the horizontal cursor 1 is used alone, the horizontal cursor 1 is installed at the corresponding position of the traction part by fixing the bolt 3, and the connecting structure is replaced by a quick-connect structure to connect with the horizontal cursor 1, that is, the connecting bolt of the quick-connect structure is threadedly connected to the threaded hole below one end of the horizontal cursor, and the hose is connected to the gear box of the traction part, so that the lubricating oil transported by the hose directly enters the horizontal cursor.

[0032] When the vertical cursor 2 is used alone, the vertical cursor 2 is installed at the corresponding position of the traction part by fixing the bolt 3, and the air plug 11 and the sealing ring on the original horizontal cursor are connected to the upper end of the vertical cursor 2 instead of the connecting structure 6, that is, the air plug is threadedly connected to the threaded hole at the upper end of the vertical cursor to close the upper end, and the lower end of the vertical cursor is connected to the quick-connect structure, and the hose of the quick-connect structure is connected to the gear box of the traction part.

[0033] When horizontal cursor 1 and vertical cursor 2 are used in combination, the horizontal cursor and the vertical cursor are connected together through a connection structure (such as Figure 1 As shown in the figure, adjust the direction of the horizontal cursor relative to the vertical cursor according to the actual work needs, install the horizontal cursor 1 and the vertical cursor 2 at the corresponding position of the traction part through multiple fixing bolts 3, connect the quick connection structure to the lower end of the vertical cursor, and connect its hose to the traction part gear box. Figure 3 As shown, it is a structural schematic diagram of the combined use of the coal mining machine oil temperature and oil level display device installed in the traction part of the coal mining machine. Compared with the traditional long cursor 7 installed in the middle of the traction part, the utility model coal mining machine oil temperature and oil level display device can be installed on both sides of the walking part according to the use requirements. It has a wide display range and strong adaptability to the installation position. It can display the oil temperature and oil level under normal working conditions, and can also display the oil temperature and oil level status under large inclination working conditions, making the utility model coal mining machine oil temperature and oil level display device more applicable.
