Description

Technical Field

[0001] This utility model relates to the field of fiberglass board production technology, specifically to a directional rotating single-arm crane for cleaning steel plates. Background Technology

[0002] Fiberglass boards are rigid sheets formed by stacking multiple layers of prepreg sheets with their edges aligned, and then pressing them together using a hot press. During the pressing process, multiple sets of prepreg sheets are typically pressed simultaneously, with steel plates separating the top and bottom sets (steel plates are required on both the top and bottom surfaces). The steel plates distribute pressure and maintain the shape during hot pressing. During the pressing process, oily additives and other substances from the prepreg sheets may remain on the surface of the steel plates. To prevent this from affecting subsequent use, the steel plates need to be thoroughly cleaned.

[0003] Most fiberglass board manufacturers are equipped with steel plate cleaning lines. Currently, the steel plates for the cleaning lines are typically loaded by horizontal transfer suction cranes or overhead cranes. Both require a large amount of space to operate. If the factory space where the cleaning line is located is limited, the factory often needs to be modified, which makes installation difficult and increases costs. Utility Model Content

[0004] The purpose of this utility model is to provide a directional rotating single-arm crane for steel plate cleaning, which can lift steel plates in a limited space and meet the requirements of steel plate cleaning lines.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A directional rotating single-arm crane for cleaning steel plates includes a column fixed to a ground foundation, a power assembly at the top of the column, a boom that rotates horizontally under the drive of the power assembly, a main shaft suspended at the cantilever end of the boom, an adsorption assembly connected to the lower end of the main shaft, and a directional holding mechanism disposed within the boom. During the horizontal rotation of the boom, the directional holding mechanism drives the main shaft to rotate in the opposite direction at equal angles, so that the direction of the steel plates adsorbed by the adsorption assembly remains unchanged.

[0007] In a further embodiment, the orientation holding mechanism includes:

[0008] A fixed gear is fixed on a vertical shaft, which is connected to the housing of the power assembly or the column. It is located at the rotation center of the boom and does not rotate with the boom.

[0009] The movable gear is of the same specification as the fixed gear and meshes with the fixed gear through an intermediate gear. When the boom rotates horizontally, it drives the movable gear to revolve around the fixed gear. Under the action of the intermediate gear, the movable gear achieves rotation in the opposite direction to the boom's rotation.

[0010] The drive pulley is coaxially mounted with the movable gear and rotates in the same direction as the movable gear;

[0011] The driven pulley is located at the upper end of the main shaft, is of the same specification as the driving pulley, and is connected to the driving pulley via a synchronous belt.

[0012] In a further embodiment, the power assembly includes a disc reducer mounted on the top of the column, with the input end of the disc reducer connected to a servo motor and the output end connected to the boom.

[0013] In a further embodiment, the adsorption assembly includes a frame fixed to the lower end of the main shaft, several cylinders mounted on the frame, and suction cups mounted on the lower end of the push rods of each cylinder, with the suction cups connected to a negative pressure device.

[0014] This utility model has the following beneficial effects:

[0015] This utility model is a single-column single-arm crane. The column occupies a small area, and part of the space under the arm can be used as part of the steel plate storage station. Multiple steel plate storage stations can be set within the rotation range of the arm, which has a high space utilization rate. It can complete the transfer and handling of steel plates in a small factory without major modifications, thus saving costs.

[0016] This invention utilizes a directional holding mechanism within the boom to maintain the orientation of the steel plate during the lifting process, ensuring that the steel plates are neatly arranged. After the steel plates are transferred between various workstations, they do not need to be redirected, simplifying the operation process and improving production efficiency.

Detailed Implementation

[0024] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but the present utility model is not limited to the following embodiments.

[0025] In the description of this utility model, terms such as "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] like Figure 1 As shown, this embodiment provides a directional rotating single-arm crane for steel plate cleaning, installed on the side of the steel plate cleaning line 17, including a column 1, a power assembly, a boom 3, a main shaft 4, and an adsorption assembly. The lower end of the column 1 is fixed to a concrete foundation, and the power assembly is installed on the upper end of the column 1. The power assembly has a disc reducer 2 and a servo motor. The servo motor inputs power to the disc reducer 2, and the disc reducer 2 is connected to one end of the boom 3 through a flange structure at its output end, thereby driving the boom 3 to rotate horizontally. The other end of the boom 3 is a cantilever end, with the main shaft 4 suspended vertically. The lower end of the main shaft 4 is equipped with an adsorption assembly for adsorbing steel plates 19. The adsorption assembly includes a frame 5 horizontally fixed to the lower end of the main shaft 4, several cylinders 6 installed around and inside the frame 5, and suction cups 7 installed at the lower end of the push rods of each cylinder 6. The suction cups 7 are connected to a negative pressure device.

[0028] In the above structure, after the servo motor starts, the disc reducer 2 drives the boom 3 to rotate. The boom 3 reciprocates directly at the workstation. When it reaches the designated workstation, the cylinder 6 drives the suction cup 7 to descend. After contacting the suction cup 7, the negative pressure device is activated, which can lift the steel plate 19. The cylinder 6 then drives the suction cup 7 to rise, and then it is hoisted to another workstation. The cylinder 6 drives the suction cup 7 to descend, and then the negative pressure is cut off, and the suction cup 7 releases the steel plate 19. In order to accommodate the descending height of the suction cup 7, the steel plate 19 can be stacked on the hydraulic lifting device, or another set of cylinders 6 can be installed on the main shaft 4 to drive the frame 5 to be further raised and lowered.

[0029] like Figure 4 As shown, in one embodiment, stacks of steel plates 19 are transported by a carrier to the second station 18.2, with their orientation substantially parallel to the conveying direction of the cleaning line. The first station 18.1, serving as the loading station for the steel plate cleaning line 17, requires the steel plates 19 to be loaded along the conveying direction of the cleaning line. This necessitates that the orientation of the steel plates 19 remain substantially unchanged during the process of being hoisted from the second station 18.2 to the first station 18.1. The same applies to the third station 18.3, which serves as a backup station for the steel plates 19.

[0030] The solution to the above problem in this embodiment is as follows: during the horizontal rotation of the boom 3, a directional holding mechanism set in the boom 3 drives the main shaft 4 to rotate in the opposite direction at the same angle, so that the direction of the steel plate 19 adsorbed by the adsorption component remains unchanged.

[0031] like Figure 2 , Figure 3 As shown, the orientation and holding mechanism includes a fixed gear 11, a movable gear 13, an intermediate gear 12, a driving pulley 14, a driven pulley 15, and a synchronous belt 16.

[0032] The fixed gear 11 is fixedly mounted on the vertical shaft 8. The lower end of the vertical shaft 8 is connected to the housing of the power assembly or the column 1, and the upper end extends into the interior of the boom 3 after passing through the flange structure of the disc reducer 2 and the bottom surface of the boom 3. To improve stability, a bearing can be added between the upper end of the vertical shaft 8 and the boom 3. In this embodiment, the vertical shaft 8 is located at the rotation center of the boom 3 and does not rotate with the boom 3. Therefore, when the boom 3 rotates, the fixed gear 11 remains stationary.

[0033] The movable gear 13 is of the same specification as the fixed gear 11 and meshes with the fixed gear 11 through an intermediate gear 12. The first rotating shaft 9 of the intermediate gear 12 and the second rotating shaft 10 of the movable gear 13 are both vertically mounted inside the boom 3 via bearings. Figure 3As shown, when the boom 3 rotates horizontally, it drives the movable gear 13 and the intermediate gear 12 to revolve around the fixed gear 11. During the revolution, the intermediate gear 12 rotates by meshing with the fixed gear 11, and then drives the movable gear 13 to rotate in the opposite direction to the boom 3.

[0034] The driving pulley 14 is mounted on the second rotating shaft 10 of the movable gear 13 and rotates in the same direction as the movable gear 13. The driven pulley 15 is located on the upper end of the main shaft 4, is of the same specification as the driving pulley 14, and is connected to the driving pulley 14 via a synchronous belt 16. When the movable gear 13 rotates, it drives the main shaft 4 to rotate through the driving pulley 14, the synchronous belt 16, and the driven pulley 15, so that the adsorption assembly connected to the main shaft 4 always maintains a fixed orientation. Specifically, as shown... Figure 3 The direction indicator mark A is shown in the diagram.

[0035] The working principle of this implementation is as follows: When the servo motor rotates, the disc reducer 2 drives the boom 3 to rotate in the horizontal plane, thereby causing the adsorption component to move back and forth between various workstations. The adsorption component adsorbs and releases the steel plate 19, allowing it to circulate between the workstations. During the rotation of the boom 3, the orientation and holding mechanism drives the main shaft 4 and the adsorption component to rotate at the same angle (equal to the rotation angle of the boom 3) and in the opposite direction, so that the orientation of the steel plate 19 adsorbed by the adsorption component remains unchanged, reducing the work of subsequent angle adjustment.

[0036] The above description is merely a preferred embodiment of this utility model. For those skilled in the art, various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
