[0023] Embodiment one

[0024] As Figures 1 to 4As shown, this utility model provides a dual-pump lubrication device with an elevated oil tank, including an elevated oil tank 1 and a dual-pump structure 2. The elevated oil tank 1 is installed above the dual-pump structure 2 and is at a relatively high height above the ground. The elevated oil tank 1 and the dual-pump structure 2 are connected by an oil pipe. The device is characterized in that: a fixed base 3 is provided at the lower end of the elevated oil tank 1 to provide upward support; extension plates 31 are symmetrically provided at both ends of the fixed base 3 for fixing a rotary motor 33; and rectangular grooves 32 are symmetrically provided on the upper surface of the fixed base 3. The rotary motor 33 is located at the upper end of the extension plates 31. A lead screw assembly 34 is connected to the output shaft on the right side of the rotary motor 33. The structure of the lead screw assembly 34 mainly includes a screw rod, a... The components include nuts, steel balls, preload plates, reversers, and dust collectors. When the lead screw acts as the driving element, the nut will convert the rotation angle of the lead screw into linear motion according to the lead of the corresponding specification. The passive workpiece can be connected to the nut through the nut seat to achieve the corresponding linear motion. The lead screw assembly 34 is located in the groove of the rectangular slot 32. The upper end of the nut of the lead screw assembly 34 is connected to the connecting block 35. The upper end of the connecting block 35 is connected to the moving plate 36. The rotary motor 33 generates rotational motion, which causes the lead screw assembly 34 to convert the rotational motion into linear motion, driving the connecting block 35 and the moving plate 36 to move. Fixed plates 37 are symmetrically provided at the front and rear ends of the two moving plates 36.

[0025] Furthermore, such as Figure 3 As shown, the fixing plate 37 has a circular hole 38 in the middle, and a screw 39 is threaded into the circular hole 38. A clamping plate 310 is provided at the end of the screw 39 near the high-level oil tank 1. Rotating the screw 39 causes it to advance continuously in the circular hole 38, which changes the distance between the two clamping plates 310. This is suitable for high-level oil tanks 1 of different widths, has high applicability, and also plays an auxiliary role in fixing and clamping, increasing the safety of the high-level oil tank 1 at high altitudes and preventing it from falling.

[0026] Furthermore, such as Figure 1 As shown, the rectangular groove 32 is symmetrically provided with limiting grooves 311 on the front and rear sides. The limiting grooves 311 are provided with guide rails 312. The outer surface of the guide rails 312 is sleeved with a second connecting block 313. The upper end of the second connecting block 313 is connected to a moving plate 36, which limits the moving position of the moving plate 36 and ensures that the moving plate 36 moves horizontally left and right, thereby increasing the clamping stability of the high-level oil tank 1.

[0027] Furthermore, such as Figure 1As shown, the lower end of the high tank 1 is provided with an oil inlet 12, which is in communication with the inside of the high tank 1, and the lower end of the left side of the oil inlet 12 is provided with a blowdown port 13, which is connected together through a pipeline, and the end of the blowdown port 13 is connected with a sealing cover. Through the arrangement of the blowdown port 13, the oil inside the high tank 1 can be discharged through the blowdown port 13 for cleaning when the equipment is stopped. The lower side of the blowdown port 13 is provided with a one-way port 14. The oil in the main tank 21 is conveyed to the one-way port 14 through the oil pump 22, the double-switching filter 23, the cooler 24 and other components. The one-way port 14 is provided with a ball valve to control the on-off and flow of the one-way port 14. The lower side of the one-way port 14 is provided with a two-way port 19. In an emergency, the main tank 21 stops supplying oil, and then the oil in the high tank 1 is output from the two-way port 19 under the action of the height difference and gravity, and is conveyed to the oil pump 22 through the heat preservation pipeline, so as to prevent damage caused by empty burning.

[0028] Further, the right upper side of the high tank 1 is provided with a backflow port 15. When the oil is overfilled, the oil is returned to the main tank 21 through the backflow port 15. The upper right side of the high tank 1 is provided with an upper cover 16. The upper cover 19 can open the upper side of the high tank 1, so as to clean the inside of the high tank 1. The left side of the upper cover 16 is provided with an oil level detector 17. When the oil level detector 17 detects that the oil amount is too much, the ball valve in the backflow port 15 is opened, so that the excess oil is returned to the main tank 21 through the backflow port 15. The left side of the oil level detector 17 is provided with a filter 18.

[0029] Further, as shown in the figure, Figure 4 The double-pump structure 2 includes a main tank 21. The upper front side of the main tank 21 is provided with two oil pumps 22, which are placed up and down. The rear left side of the oil pump 22 is provided with a double-switching filter 23. The right side of the double-switching filter 23 is provided with a cooler 24. The oil in the main tank 21 is extracted along the pipeline under the action of the oil pump 22, is filtered by the double-switching filter 23 and is cooled by the cooler 24, and is conveyed to the one-way port 14 and then to the high tank 1.

[0030] Working process: first, the oil in the main oil tank 21 is delivered to the double switching filter 23 by the oil pump 22, and the oil is filtered; further, the filtered oil is cooled by the cooler 24 and delivered to the one-way port 14, the oil inlet 12, and then enters the high oil tank 1; further, the oil level detector 17 detects the oil amount in the high oil tank 1, and when the oil amount is too much, the ball valve in the backflow port 15 is opened, so that the excess oil returns to the main oil tank 21 through the backflow port 15; further, when the main oil tank 21 stops supplying oil due to an emergency, the oil in the high oil tank 1 is output from the two-way port 19 under the action of the height difference and gravity, and is delivered to the oil pump 22 through the heat preservation pipeline, so as to prevent damage caused by empty burning.
