[0021] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0022] This utility model discloses an oil delivery arm structure with residual oil collection function, comprising a housing 1, a base plate 2, a rotating assembly, a mounting base I 12, an oil delivery arm body 13, a pushing assembly, a connecting assembly, a connecting pipe 20, and a hot air blower 21; the specific structure is as follows: Figure 1 , Figure 2 As shown, a base plate 2 is horizontally arranged on the left side of the upper surface of the horizontally arranged housing 1, and the base plate 2 is horizontally rotatably connected to the housing 1 via a rotating assembly; the oil transfer arm body 13 is horizontally arranged and inclined downwards to the left, and is fixedly arranged on the upper surface of the base plate 2 by the mounting seat I 12; the front end hose of the oil transfer arm body 13 is arranged to the left, and its oil inlet end extends out of the base plate 2 to the upper right, and a flange 14 is coaxially sleeved on it; wherein, the flange 14 is annular, and its inner diameter matches the inner diameter of the oil transfer arm body 13, and its outer diameter is larger than the outer diameter of the oil transfer arm body 13, thereby connecting the pipeline connected to the oil source through the flange 14 and the oil transfer arm body 13 in a screw-sealed connection.

[0023] The housing 1 of this utility model is a horizontally arranged hollow cuboid structure, and hydraulic cylinders 3 are vertically and symmetrically arranged at the four right corners of its inner bottom surface, such as... Figure 1 , Figure 2 As shown, the four hydraulic cylinders 3 operate synchronously, and the piston rod of each hydraulic cylinder 3 extends vertically downward from the lower surface of the housing 1 and is connected to the corresponding caster wheel 4. Support legs 5 are also vertically and symmetrically arranged at the four right angles of the lower surface of the housing 1, and each support leg 5 is located within the square area enclosed by the four caster wheels 4. When in the upper limit position, the lower end face of each caster wheel 4 is positioned above the horizontal plane where the lower end of the corresponding support leg 5 is located. Driven by the hydraulic cylinders 3, this invention switches between a moving state and a working state through the cooperation of the caster wheels 4 and the support legs 5.

[0024] The rotating assembly of this utility model is configured to operate independently of the four hydraulic cylinders 3, and includes a side plate 6, a motor 10, a main bevel gear 8, a driven bevel gear 9, a gear shaft 7, and a roller assembly 11; as shown Figure 1 , Figure 2 As shown, a gear shaft 7 is vertically arranged inside the housing 1 relative to the base plate 2. The upper and lower ends of the gear shaft 7 are rotatably connected to the inner top and bottom surfaces of the housing 1, respectively. Its upper end extends vertically upwards beyond the upper surface of the housing 1 and is coaxially fixedly connected to the middle of the lower surface of the base plate 2. A driven bevel gear 9 is horizontally and coaxially sleeved and fixed on the gear shaft 7 relative to the inside of the housing 1, and the driven bevel gear 9 and the housing 1 are not interfered with each other. A matching side plate 6 is vertically arranged inside the housing 1 relative to the left side of the driven bevel gear 9. A motor 10 is horizontally arranged inside the housing 1 between the driven bevel gear 9 and the side plate 6. The fixed end of the motor 10 is screwed to the corresponding side of the side plate 6, and its output end is horizontally arranged towards the driven bevel gear 9, meshing with the driven bevel gear 9 through a main bevel gear 8. Driven by the motor 10, the gear shaft 7 rotates around its own axis through the meshing of the main bevel gear 8 and the driven bevel gear 9, thus driving the base plate 2 to rotate horizontally.

[0025] like Figure 1 , Figure 2 As shown, a ring of rollers 11 is connected to the upper surface of the housing 1 and abuts against the lower surface of the base plate 2. The ring of rollers 11 is coaxial with the base plate 2 and is not interfered with by the gear shaft 7. Each roller group 11 is conical, with one end near the gear shaft 7 being the small end and the other end being the large end, so as to accommodate the smaller linear velocity near the gear shaft 7 when the base plate 2 rotates.

[0026] This utility model has a horizontally mounted fixing seat 15 on the upper surface of the housing 1 relative to the right side of the base plate 2, and a mounting seat II 19 is horizontally mounted on the upper surface of the fixing seat 15. Figure 1 , Figure 2As shown, the mounting base II 19 moves horizontally on the fixed base 15 by pushing the component, and a connecting pipe 20 is horizontally arranged on its upper surface, coaxial with the oil delivery arm body 13. The right end of the connecting pipe 20 is sealed and connected to the hot air blower 21, and a connecting component is provided at its left end. Driven by the pushing component, the connecting pipe 20 moves horizontally to the left, and is sealed and connected to the oil delivery arm body through the connecting component, and hot air is blown into the oil delivery arm body 13 by the hot air blower 21. The oil delivery arm body 13 and the connecting pipe 20 are arranged in the same inclined direction and the inclination angle of the oil delivery arm body 13 is 2~5°.

[0027] The pushing assembly of this utility model includes a first electric push rod 16, a stiffening plate, a slide rail 18, a slider 17, and a limiting plate; as shown... Figure 1 , Figure 2 As shown, the heights of mounting base I 12, mounting base II 19, and fixed base 15 must ensure that the oil delivery arm body 13 and the connecting pipe 20 are coaxially aligned. A first electric push rod 16 is horizontally mounted on the right side of mounting base II 19. The tail of the first electric push rod 16 is fixedly mounted on the corresponding position on the upper surface of the fixed base 15 via a reinforcing rib, and its pushing end is horizontally to the left and screwed to the right side of mounting base II 19, pushing mounting base II 19 to perform horizontal reciprocating motion on the upper surface of the fixed base 15. On the lower surface of mounting base II 19… The mounting base 19 is also provided with horizontally arranged sliders 17 symmetrically spaced at intervals, and the length of each slider 17 is consistent with the horizontal length of the mounting base 19. On the upper surface of the fixed base 15, a slide rail 18 matching the slider 17 is also provided horizontally relative to the position of each slider 17. The cooperation between the slider 17 and the slide rail 18 ensures the stability of the horizontal movement of the mounting base 19. Limiting plates are also fixed at the left and right ends of each slide rail 18, and the horizontal movement of the mounting base 19 is limited to the left and right by the limiting plates.

[0028] The connecting assembly of this utility model includes a cover 22, a fixing plate 25, a reinforcing plate 27, an airbag 24, a second electric push rod 26, and an arc-shaped plate; as shown Figure 1 , Figure 2As shown, the connecting pipe 20 is a hollow cylindrical structure, and its right end extends obliquely upward to form a mounting base II 19, which is fixedly connected to the hot air blower 21. A matching cover 22 is coaxially sleeved and fixedly fitted onto the left end face of the connecting pipe 20. The cover 22 is a horizontally arranged hollow cylindrical structure with an outer diameter larger than that of the connecting pipe 20. Several reinforcing plates 27 are evenly distributed and vertically spaced along the circumference of the cover 22 between its right outer surface and the connecting pipe 20, thereby reinforcing and fixing the cover 22. The right outer side of the housing 22 is also coaxially and vertically embedded with a through hole 23. The diameter of the through hole 23 is smaller than the inner diameter of the connecting pipe 20, and the housing 22 is sealed and connected to the connecting pipe 20 through the through hole 23. The left outer side of the housing 22 is also coaxially embedded with a circular groove with a diameter larger than the outer diameter of the flange 14. The circular groove is connected to the interior of the housing 22, and the right inner side of the housing 22 is tightly fitted to the right side of the flange 14 through the circular groove, thereby making the oil supply arm body 13 sealed and connected to the connecting pipe 20 through the through hole 23.

[0029] In this invention, a matching fixing plate 25 is coaxially sleeved and fixed on the left outer side of the cover 22 relative to the outer side of the circular groove. Figure 1 , Figure 2 As shown, the fixing plate 25 is an open-ended annular structure with an inner diameter larger than the diameter of the circular groove and an outer diameter smaller than the outer diameter of the cover 22. Several second electric push rods 26 are evenly spaced and vertically arranged along the circumferential direction at the center of the outer circumferential surface of the fixing plate 25. The fixed end of each second electric push rod 26 is screwed to the corresponding position on the outer circumferential surface of the fixing plate 25, and its tail is fixedly connected to the corresponding position on the left outer side of the cover 22 via a rib. The pushing end of each second electric push rod 26 extends radially into the interior of the fixing plate 25 and is screwed to the outer arc surface of the corresponding arc plate. The inner... The arc surfaces all match the right end of the outer circumference of the oil supply arm body 13 and are coaxially set with the right end of the oil supply arm body 13. Driven by the second electric push rod 26, the inner arc surface of each arc plate abuts against the outer circumference of the right end of the oil supply arm body 13 and connects the connecting pipe 20 to the oil supply arm body 13. An airbag 24 is also coaxially sleeved between the inside of the cover 22 and the right end of the oil supply arm body 13. The airbag 24 is inflated and abuts against the inside of the cover 22 and the outer circumference of the right end of the oil supply arm body 13, thereby ensuring a sealed connection between the connecting pipe 20 and the right end of the oil supply arm body 13.

[0030] The horizontal leftward limit position of the mounting base II 19 of this utility model must ensure that the right inner side of the cover 22 is coaxially fitted with the right side of the flange 14, and its horizontal rightward limit position must ensure that the connecting component is completely detached from the oil supply arm body 13, and that the oil supply arm body 13 does not interfere with the horizontal rotation of the mounting base I 12.

[0031] The motor 10 and electric push rod involved in this utility model are both existing general products, and they are all controlled by a controller so that the movements of the motor 10, the first electric push rod 16, and the second electric push rod 26 can be precisely controlled according to the residual oil recovery operation of the oil conveying arm body 13. The start and end of each movement of the motor 10, the first electric push rod 16, and the second electric push rod 26 are obtained through repeated experiments and stored in the controller for easy retrieval later. Thus, when performing the residual oil recovery operation of the oil conveying arm body 13, it is only necessary to select the corresponding program instruction to ensure that the oil conveying arm body 13 and the connecting pipe 20 are set in a straight line with the same tilt angle. This is the conventional control setting of the motor 10 and the electric push rod, which is existing technology known to those skilled in the art, and therefore will not be described in detail here.

[0032] In addition, the present invention can control the front end hose of the oil delivery arm body 13 to swing horizontally in the area relative to the left half of the base plate 2 by the motor 10, so as to prevent the front end hose of the oil delivery arm body 13 from rubbing against the connecting pipe 20. This is an existing control technology, so it will not be described in detail here.

[0033] The working principle of this utility model:

[0034] First, with human assistance, the housing 1 is moved closer to the oil source using the casters 4; then, the piston rod of the hydraulic cylinder 3 retracts, causing the casters 4 to lift, so that the outriggers 5 contact the ground, ensuring the stability of the working state; then, the pipeline connected to the oil source is sealed and bolted to the oil delivery arm body 13 through the flange 14, so that the oil delivery arm body 13 is sealed and connected to the oil source, and at this time, the oil delivery operation can be carried out through the hose at the front end of the oil delivery arm body 13;

[0035] After the oil transfer is completed, and before the residual oil is discharged from the oil transfer arm body 13, the pipe connected to the oil source is first removed from the flange 14. Then, driven by the rotating component, the oil transfer arm body 13 rotates horizontally with the base plate 2 until it is coaxially set with the connecting pipe 20. Then, through the cooperation of the connecting component and the pushing component, the cover 22 is coaxially sleeved on the oil inlet end of the oil transfer arm body 13. At this time, through the cooperation of the cover 22 and the corresponding air bag 24, the connecting pipe 20 is sealed and connected to the oil transfer arm body 13. Then, the hose outlet end at the front end of the oil transfer arm body 13 is placed on the recovery box 28. Then, hot air can be blown into the interior of the oil transfer arm body 13 by the hot air blower 21, so that the residual oil attached to the oil transfer arm body 13 is detached and collected into the recovery box 28 through the hose.

[0036] The beneficial effects of this utility model are:

[0037] (1) By using the connection component and the push component together, the hot air blower 21 can be sealed and connected to the oil conveying arm body 13 through the connecting pipe 20, so that the residual oil attached to the oil conveying arm body 13 can be removed by blowing hot air into the oil conveying arm body 13 and collected into the recovery box 28 through the hose, thereby improving the residual oil collection efficiency and reducing the loss.

[0038] (2) By setting a rotating component, the present invention enables the oil conveying arm body 13 to rotate horizontally with the base plate 2, thereby improving the flexibility of use of the oil conveying arm body 13.

[0039] (3) The utility model uses the hydraulic cylinder 3, the universal wheel 4 and the outrigger 5 together to facilitate the switching between the moving state and the working state, and ensures the stability during operation.

[0040] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model.

The tail of the first electric push rod is fixedly mounted on the upper surface of the fixed base at a corresponding position via a stiffener, and its pushing end is horizontally screwed to the right side of the mounting base II, pushing the mounting base II to perform horizontal reciprocating motion on the upper surface of the fixed base. A slider is symmetrically arranged horizontally at intervals on the lower surface of the mounting base II, and the length of each slider is consistent with the horizontal length of the mounting base II. A slide rail matching the slider is horizontally arranged on the upper surface of the fixed base relative to each slider position, and the cooperation between the slider and the slide rail ensures the stability of the horizontal movement of the mounting base II. Limiting plates are fixed at both ends of each slide rail, and the horizontal movement of the mounting base II is limited by the limiting plates.

7. The oil conveying arm structure with residual oil collection function according to claim 6, characterized in that: The connecting assembly includes a cover, a fixing plate, and a reinforcing plate. The connecting pipe is a hollow cylindrical structure, with its right end extending upwards at an angle from the mounting base II, and is fixedly connected to the hot air blower. A matching cover is coaxially sleeved and fixedly installed on the left end face of the connecting pipe. The cover is a horizontally arranged hollow cylindrical structure with an outer diameter larger than that of the connecting pipe. Several reinforcing plates are evenly spaced and vertically arranged along its circumference between its right outer side and the connecting pipe, thereby reinforcing and fixing the cover. A through hole is coaxially and vertically embedded on the right outer side of the cover. The diameter of the through hole is smaller than that of the connecting pipe, and the cover is sealed and connected to the connecting pipe through the through hole. A circular groove with a diameter larger than that of the flange outer diameter is coaxially embedded on the left outer side of the cover. The circular groove is connected to the interior of the cover, and the right inner side of the cover is pressed against the right side of the flange through the circular groove, thereby sealing and connecting the oil supply arm body to the connecting pipe through the through hole.

8. The oil conveying arm structure with residual oil collection function according to claim 7, characterized in that: It also includes a fixing plate, an airbag, second electric push rods, and an arc-shaped plate; a matching fixing plate is coaxially sleeved and fixed on the left outer side of the cover relative to the outer side of the circular groove. The fixing plate is an open-ended annular structure with an inner diameter larger than the diameter of the circular groove and an outer diameter smaller than the outer diameter of the cover; several second electric push rods are evenly distributed and perpendicularly arranged along the circumferential direction at the middle position of the outer circumferential surface of the fixing plate. The fixed end of each second electric push rod is screwed and fixed to the corresponding position of the outer circumferential surface of the fixing plate, and its tail is fixedly connected to the corresponding position of the left outer side of the cover through a rib plate; the pushing end of each second electric push rod extends radially to... The fixed plate is screwed to the outer arc surface of the corresponding arc plate. The inner arc surface of each arc plate matches the right end of the outer circumference of the oil supply arm body and is coaxially set with the right end of the oil supply arm body. Driven by the second electric push rod, the inner arc surface of each arc plate abuts against the outer circumference of the right end of the oil supply arm body and connects the connecting pipe to the oil supply arm body. An air bladder is also coaxially sleeved between the inside of the cover and the right end of the oil supply arm body. The air bladder is inflated and abuts against the inside of the cover and the outer circumference of the right end of the oil supply arm body, thereby ensuring a sealed connection between the connecting pipe and the right end of the oil supply arm body.

9. The oil conveying arm structure with residual oil collection function according to claim 8, characterized in that: The horizontal leftward limit position of the mounting seat II must ensure that the right inner side of the cover is coaxially aligned with the right side of the flange, and its horizontal rightward limit position must ensure that the connecting assembly is completely detached from the oil delivery arm body, and that the oil delivery arm body does not interfere with the horizontal rotation of the mounting seat I.
