DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1:

[0028] A pulley cleaning platform includes a cleaning table 1, a shaft structure 2 for inserting and placing pulley wheels is provided above the cleaning table 1, a safety pin 3 is provided at one end of the outer side of the shaft structure 2 to prevent the pulley wheels from falling off, and the other end of the shaft structure 2 is connected to the cleaning table 1 through a tooling frame. Figure 1 、 Figure 2 As shown, in this embodiment, the tooling frame is a tooling column 4. In actual use, the length of the cleaning table 1 can be increased, and multiple tooling columns 4 can be vertically fixed on the cleaning table 1. Figure 1 The figure shows a situation where two tooling columns 4 are set up, so that multiple pulleys can be cleaned at the same time. Moreover, since the pulley is in a suspended state, the grooves on the side of the pulley will not hit the ground, thereby avoiding damage to the pulley. A plurality of supporting ribs for reinforcement are set between the tooling columns 4 and the cleaning table 1.

[0029] The upper end of the tooling column 4 is fixedly connected to one end of the shaft structure 2. The shaft structure 2 in this embodiment is a fixed shaft, so the pulley can be manually rotated to adjust the angle during cleaning. As shown in the figure, the diameter of the fixed shaft should be set smaller than the center hole of the pulley. The fixed shaft is vertically welded to the tooling column 4 so that the fixed shaft is parallel to the plane on the cleaning table 1. In actual use, the pulley can be lifted and inserted into the fixed shaft. Since the diameter of the fixed shaft is smaller than the diameter of the center hole, it can be used for cleaning pulleys with various center holes. Moreover, since the diameter of the fixed shaft is small, it is also convenient to manually rotate the pulley to adjust the angle for cleaning all around.

[0030] Example 2:

[0031] The cleaning platform in the aforementioned embodiment is only a support frame for the pulley and cannot automatically clean the sludge on the pulley. In this embodiment, the design is further improved to automatically scrape off the sludge on the pulley.

[0032] Specifically, the shaft structure 2 is actually rotatably connected and arranged on the tooling frame, and the rotation of the shaft structure 2 is used to drive the rotation of the pulley, and the tooling frame is designed as a box structure, and the internal space of the box is used to set a driving part for driving the shaft structure 2 to rotate. Specifically, the box structure includes a first side plate 5 and a second side plate 6 that are parallel to each other. The first side plate 5 and the second side plate 6 are both vertically fixed on the cleaning table 1, and the shaft structure 2 passes through the first side plate 5 and the second side plate 6 and is rotatably connected.

[0033] Furthermore, when the pulley is driven to rotate, a cleaning mechanism for the oil sludge on the side of the pulley needs to be provided, such as Figure 3 As shown, it includes an inner cleaning structure 8 and an outer cleaning structure 9; specifically, a rotating plate 7 coaxially arranged with the shaft structure 2 is rotatably connected to the first side plate 5, and the rotating plate 7 is provided with an inner cleaning structure 8 for cleaning the inner side of the pulley; the cleaning platform 1 is also provided with an outer cleaning structure 9 for cleaning the outer side of the pulley; during actual use, the rotating pulley cooperates with the cleaning structures on both sides to achieve the cleaning of the oil sludge on the side of the pulley.

[0034] Example 3:

[0035] As an improvement to the second embodiment, in order to facilitate the installation and removal of the pulley on the shaft structure 2, the shaft structure 2 is designed in the first embodiment to have a diameter smaller than the center hole. Therefore, it is not convenient to fix the pulley and drive the pulley to rotate through the shaft structure 2. Therefore, in this embodiment, the shaft structure 2 needs to be designed to be adaptable to pulleys with different center hole diameters, and the pulley can also be driven to rotate through the shaft structure 2.

[0036] Specifically, the part of the shaft structure 2 where the pulley is placed needs to be designed as a variable diameter structure, that is, a variable diameter structure 10 is provided on the shaft structure 2. When the pulley is placed on this part, by controlling this structure, the diameter of this part can be increased, and this part can be tightened in the center hole so that the shaft structure 2 is coaxial with the center hole. Then, the center hole is tightened and fixed from the inside using the variable diameter structure so that the pulley and the shaft structure 2 are fixed, and the pulley can be driven to rotate.

[0037] Specific examples Figure 4 、 Figure 5 As shown, the variable diameter structure 10 is adapted to pulleys of different inner diameters. Figure 4The structure diagram shown in FIG is that the top block 12 in the variable diameter structure 10 does not extend out of the outer sleeve shaft 11. Figure 5 This is a structural diagram showing that the diameter of the variable diameter structure 10 increases after the top block 12 is extended, and the center hole of the pulley can be supported at this time; specifically, the variable diameter structure 10 includes an outer sleeve shaft 11, a top block 12, and a center shaft 13. The center shaft 13 is coaxially arranged inside the outer sleeve shaft 11 and can move along the axial direction. The top block 12 is slidably connected to the outer sleeve shaft 11, and the top block 12 slides along the radial direction of the outer sleeve shaft 11. There are multiple top blocks 12 around the outer sleeve shaft 11. When the center shaft 13 moves along the axial direction, the multiple top blocks 12 are synchronously extended and tightened to fix the center hole of the pulley. The top block 12 is provided with a triangular inner groove 14 on one side of the inner side of the outer shaft 11, and a triangular wedge 15 is fixed on the side wall of the central shaft 13. The wedge 15 cooperates with the inner groove 14, and when the wedge 15 moves, the top block 12 is lifted by the inclined surface; the principle of its diameter change is that the axial position of the central shaft 13 is moved, the wedge 15 is pulled, and the top block 12 is lifted out of the outer shaft 11 by the cooperation of the inclined surface of the wedge 15 and the inclined surface of the triangular inner groove 14. Figure 3 As shown, a plurality of top blocks 12 are provided in each circle around the shaft structure 2, and the positions of the top blocks 12 between the circles are staggered to make up for the gaps between the top blocks 12 along the axial direction, so as to achieve seamless axial connection and adapt to pulleys of different thicknesses.

[0038] One end of the central shaft 13 passes through the outer sleeve shaft 11, and the end is provided with an external thread 17, and a nut 18 is screwed on the external thread 17. Rotating the nut 18 moves the central shaft 13 and limits its rotation. A convex key 19 is also provided on the side of the central shaft 13 to limit its rotation. The central shaft 13 can be pulled by rotating the nut 18, and in order to limit the rotation of the central shaft 13, a convex key 19 is provided. The convex key 19 slides with the long groove on the inner wall of the outer sleeve shaft 11 to achieve the function of limiting the rotation of the central shaft 13. Since the top blocks 12 on all sides need to automatically fall back into the outer sleeve shaft 11 when resetting, a reset spring 16 is clamped between the two ends of the top block 12 and the outer sleeve shaft 11. Under the action of the reset spring 16, the top block 12 can fall back.

[0039] Example 4:

[0040] This embodiment provides a driving structure for the driving shaft structure 2 and the rotating plate 7. Specifically, Figure 3As shown, the shaft structure 2 passes through the axis of the rotating plate 7 and is rotatably connected thereto. A central gear 20 is fixedly provided on the shaft structure 2. A plurality of planetary gears 21 meshing with the central gear 20 are provided on the periphery of the central gear 20. The planetary gears 21 are provided on a planetary carrier 22. The planetary carrier 22 is rotatably connected to the shaft structure 2. A ring gear 23 is fixedly provided on the rotating plate 7. The ring gear 23 meshes with the planetary gears 21. By utilizing the principle of the planetary gear 21 group, when the shaft structure 2 rotates, the central gear 20 is rotated, and the central gear 20 drives the planetary gears 21 to rotate, and utilizes The rotation of the planetary gear 21 drives the ring gear 23 to rotate in the opposite direction, thereby achieving the effect of the rotating plate 7 and the shaft structure 2 rotating in the opposite direction. Furthermore, the inner cleaning structure 8 provided on the rotating plate 7 also rotates in the opposite direction of the pulley, which is more conducive to cleaning the oil stains on the pulley; the shaft structure 2 is also provided with a sprocket 24, and the cleaning table 1 is provided with a drive motor 25, which drives the shaft structure 2 to rotate through the chain 26; the shaft structure 2 is driven to operate by the drive motor 25 and the sprocket 24 and chain 26, and also drives the planetary gear 21 group to operate.

[0041] Embodiment 5:

[0042] The inner cleaning structure 8 and the outer cleaning structure 9 are both provided with an adaptive scraper structure 27. The adaptive scraper structure 27 of the inner cleaning structure 8 is fixed on the rotating plate 7 through a mounting block, and at least one set of adaptive scraper structures 27 is provided on the rotating plate 7. Figure 6 As shown, two sets of adaptive scraper structures 27 are provided on the rotating plate 7; Figure 3 As shown, the lower end of the adaptive scraper structure 27 on the outer cleaning structure 9 is hingedly connected to the slide plate 28, the slide plate 28 is slidably connected to the cleaning table 1 and its sliding direction is parallel to the setting direction of the shaft structure 2, and a foldable and retractable support rod 29 is hingedly provided between the upper end of the adaptive scraper structure 27 and the slide plate 28; it can be understood that the adaptive scraper structure 27 on the outer side of the pulley can be folded and put away, and at this time it will not hinder the installation and removal of the pulley. When cleaning is required, the outer adaptive scraper structure 27 is supported by the support rod 29 and brought close to the pulley. The provided slide plate 28 is used to drive the outer cleaning structure 9 to move close to the pulley.

[0043] like Figure 6 、 Figure 7 As shown, the adaptive scraper structure 27 includes a mounting beam 30, and the scraper structures are evenly spaced along the long sides on both sides of the mounting beam 30, and the scraper structures on both sides of the mounting beam 30 are staggered. Since the side of the pulley is not flat, but is thickened near the center hole and the outer pulley groove, and thinner between the two, in order to adapt to such different sizes, the scraper structure is arranged in double rows, and the scrapers on the two rows are staggered with each other, so that the oil sludge on the side of the pulley can be completely scraped and washed.

[0044] Furthermore, the scraper structure includes a guide rod 31, an articulated seat 32, a scraper body 33, an elastic member 34, and a limit block 35. The guide rod 31 is a prismatic rod, and the guide rod 31 is slidably connected and passes through the mounting beam 30. The first end of the guide rod 31 is provided with an articulated seat 32, and the second end is provided with a limit block 35. An elastic member 34 is provided between the mounting beam 30 and the articulated seat 32. The scraper body 33 is provided on the articulated seat 32, and the rotation axis direction of the articulated seat 32 is perpendicular to the setting direction of the mounting beam 30. In actual use When the pulley approaches the adaptive scraper structure 27, the thick walls of the inner and outer rings of the pulley will compress the elastic part 34, causing the scraper body 33 to be pressed down, and the thinner part in the middle of the pulley can be contacted by the scraper body 33 on the other scraper structure. Automatic scraping can be achieved by coordinating the relative rotation between the two. Moreover, since the scraper body 33 is set on the hinge seat 32, the scraper body 33 can not only shrink, but also rotate by using the hinge to adapt to the scraping operation of the inclined surface on the side of the pulley.

[0045] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
