Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary components for gas cylinder filling, specifically a rotating platform for filling large-capacity gas cylinders. Background Technology

[0002] Large-capacity gas cylinders, due to their weight (often around 1000kg when full) and large dimensions, are typically filled and transported horizontally (large-capacity gas cylinders generally refer to those capable of holding more than 150L). During the filling process, forklifts are required for loading and unloading. This is due to the limitations of the filling equipment itself and its layout at the gas cylinder filling company (see reference...). Figure 5 as well as Figure 6 Generally speaking, the placement of gas cylinders differs between the loading / unloading process and the filling process. Therefore, the gas cylinders need to be manually rotated before and after filling. This rotation process usually requires four people to work simultaneously, which is not only labor-intensive and inefficient, but also causes wear and tear on the outer wall of the gas cylinder. This wear and tear not only affects the service life of the gas cylinder, but also poses safety risks during transportation. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a rotating platform for filling large-capacity gas cylinders, thereby solving the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A rotating platform for filling large-capacity gas cylinders includes a lower tray mounted on a weighing platform. The top of the lower tray is provided with a rotation positioning unit for rotating large-capacity gas cylinders. The top of the rotation positioning unit is provided with a gas cylinder support unit for supporting gas cylinders of different sizes.

[0006] The beneficial effects of this utility model are as follows: During use, this utility model is generally placed on top of a weighing platform, which is used to weigh the gas being filled. This utility model, placed on top of the weighing platform, allows for adjustment of the gas cylinder's orientation before and after filling, thus facilitating forklift placement and filling. Specifically, the lower tray of this utility model does not rotate; it can be placed on the weighing platform. The rotation positioning unit and the gas cylinder support unit rotate together relative to the lower tray, thus facilitating adjustment of the gas cylinder's orientation. The gas cylinder support unit in this utility model can easily support gas cylinders of different specifications, thereby improving the utility model's versatility. It features improved filling efficiency, reduced labor intensity, and prevention of wear on the outer wall of the gas cylinder.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 To further describe this application in detail, this utility model is a rotating platform for filling large-capacity gas cylinders. The rotating platform includes a lower tray 1 set on a weighing platform 22. The top of the lower tray 1 is provided with a rotating positioning unit for realizing the rotation of large-capacity gas cylinders. The top of the rotating positioning unit is provided with a gas cylinder support unit for supporting gas cylinders of different specifications. This utility model is mainly applied to gas production enterprises. Due to the influence of the filling equipment itself and the enterprise's requirements for equipment layout, the position of the gas cylinder during loading and unloading by the forklift 20 is inconsistent with the position during filling. This utility model is mainly to solve the problems of high labor intensity and low reloading efficiency of manual rotation of gas cylinders. The relationship between the weighing platform 22 and the lower pallet 1 in this utility model is either direct placement or detachable connection. The detachable connection is a conventional bolt connection, which will not be described in detail. In actual use, the lower pallet 1 does not rotate. The gas cylinder support unit is connected to the top of the rotation positioning unit and rotates with the rotation positioning unit. In this utility model, the rotation positioning unit can be rotated by power drive or manually driven. When driven by power, a motor or other motor can be used. When driven manually, a single person can push the related universal wheels or rotating wheels, or other conventional labor-saving structures. The gas cylinder support unit described in this utility model can achieve adaptive support according to the different outer diameters of gas cylinders of different specifications; for example, it can adopt a flexible snap-fit ​​structure, etc., to improve the versatility of this utility model; this utility model is particularly suitable for gas cylinders filled with liquid products.

[0026] Furthermore, the gas cylinder support unit includes support columns 2 at least around the top of the rotary positioning unit. The top of the support columns 2 is hinged to the middle of the movable support frame 3, and rotatable support wheels 4 are provided at both ends of the movable support frame 3. To improve the structural robustness of this utility model and facilitate loading and unloading of the gas cylinder using a forklift 20, specifically, by setting the support columns 2, a certain distance is maintained between the bottom of the gas cylinder and the top of the rotary positioning unit. This distance not only prevents wear caused by contact between the outer wall of the gas cylinder and the rotary positioning unit, but also facilitates the forklift 20's forks to penetrate into the bottom of the gas cylinder. Furthermore, by hinged to the support columns 2, the two corresponding movable support frames 3 can adapt to different angles according to the diameter of the gas cylinder, thereby improving versatility.

[0027] Furthermore, the movable support frame 3 has a V-shaped or U-shaped structure, the top of the support column 2 is connected to the outer side of the middle part of the movable support frame 3, and the rotatable support wheel 4 is set on the inner side of both ends of the movable support frame 2.

[0028] Furthermore, the rotary positioning unit includes a thrust bearing 5 positioned at the top center of the lower tray 1. The top of the thrust bearing 5 has a rotary positioning part, and a rotary support part is provided around the rotary positioning part and between it and the lower tray 1. This invention preferably employs a manually driven mechanism, using the thrust bearing 5 to facilitate rotation. A single person can push the rotary positioning part to rotate, thus simplifying the rotary positioning process.

[0029] Furthermore, the rotating support includes a rotating support frame 6, and a deep groove ball bearing 7 is provided between the top of the rotating support frame 6 and the rotating positioning part. This arrangement makes the structure between the rotating positioning unit and the lower tray 1 more stable without affecting the rotation of the rotating positioning unit.

[0030] Furthermore, the rotary positioning part includes a gear 10 disposed on the top of the thrust bearing 5 and the rotary support part. A shaft 11 is inserted through the middle of the gear 10. The upper part of the shaft 11 is connected to the bottom of the upper tray 9, and the lower part of the shaft 11 is connected to the top of the lower tray 1. A positioning element is provided on the side of the gear 10. In this invention, the top of the lower tray 1 may be provided with a groove, and the bottom of the shaft 11 may be movably placed in the groove; or a bearing seat adapted to the bottom of the shaft 11 may be provided on the top of the lower tray 1, so as to achieve the purpose of the lower tray 1 not rotating, while the gear 10 and the upper tray 9 rotate synchronously; the shaft 11 in this invention is a smooth shaft, which mainly plays a role in center positioning for rotation.

[0031] Furthermore, the positioning component includes a positioning housing 12, the bottom of which is connected to the lower tray 1. The positioning housing 12 has open ends, and a limiting shaft 14 is provided inside. One end of the limiting shaft 14 near the gear 10 has a shift fork 15 that matches the internal tooth groove of the gear 10. The other end of the limiting shaft 14 has a handle 8, which is located outside the positioning housing 12. In actual use, pushing the handle 8 causes the limiting shaft 14 to move the shift fork 15 into the tooth groove of the gear 10, thus positioning the gear 10. When rotation is required, pulling the handle 8 outwards causes the limiting shaft 14 to move the shift fork 15 in the opposite direction to the gear 10, with the end of the shift fork 15 not contacting the tooth groove, allowing the gear 10 to rotate normally.

[0032] Furthermore, a limiting boss 16 is provided on the outer circumference of the end of the shift fork 15 connected to the limiting shaft 14, and a step 17 is provided in the inner center of the positioning housing 12. A spring 13 is fitted outside the limiting shaft 14 between the step 17 and the limiting boss 16. Through the above arrangement, when positioning the gear 10, the spring 13 continuously provides spring force to the shift fork 15, thereby ensuring that rotation does not occur during forklift loading, unloading, and filling, effectively improving the safety of the equipment.

[0033] Furthermore, a T-shaped limiting hole 18 is provided on the positioning housing 12 between the step 17 and the handle 8, and a limiting pin 19 connected to the limiting shaft 14 is inserted into the T-shaped limiting hole 18. By cooperating with the T-shaped limiting hole 18 and the limiting pin 19, the shift fork 15 can be limited during the rotation of the gear 10. Specifically, the gear 10 is positioned by the shift fork 15 being inserted between the teeth of the gear 10. When rotation is required, the shift fork 15 is pulled by the handle 8, and the end of the shift fork 15 is pulled out from between the teeth of the gear 10, thus canceling the limiting function and allowing the gear 10 to rotate normally. To save labor and reduce labor intensity, a structure is designed where the T-shaped limiting hole 18 and the limiting pin 19 cooperate. When the gear 10 needs to rotate, the limiting pin 19 is pulled to the upper part of the T-shaped limiting hole 18 for limiting (this working method is mainly used to continuously compress the spring 13); when the gear 10 needs to be positioned, the limiting pin 19 is inserted into the lower part of the T-shaped limiting hole 18.

[0034] The specific working process of this utility model is as follows: When using this utility model, place it on the weighing platform 22, and use a forklift 20 to place the large-capacity gas cylinder on the gas cylinder support unit. The gas cylinder support unit includes four sets of support components, in which the support columns 2 and movable support frames 3 are in a one-to-one correspondence. Each movable support frame 3 is equipped with two rotatable support wheels 4. When placing the gas cylinder, the outer wall of the gas cylinder contacts the rotatable support wheels 4, and pushes the corresponding movable support frames 3 to form a certain angle, so as to support gas cylinders of different specifications. On-site operators can push the upper tray 9 to... The rotary positioning unit drives the gas cylinder to rotate. When it rotates to the position where the filling device 21 can easily fill the cylinder, the shift fork 15 inserts into the tooth groove of the gear 10, thereby positioning the rotary positioning unit. After the gas cylinder is filled using the filling device 21, the shift fork 15 is pulled out from the tooth groove of the gear 10, and the rotary positioning unit can resume rotation. The on-site operator pushes the upper pallet 1 again to make the rotary positioning unit drive the gas cylinder to rotate. When it rotates to the position where the forks of the forklift 20 can easily reach the bottom of the gas cylinder, the positioning component positions the rotary positioning unit to facilitate the forklift 20 to transfer the gas cylinder to the transport vehicle. This utility model has a simple and robust structure. When used in conjunction with the weighing platform 22, it facilitates loading and unloading by the forklift 20 and filling of gas cylinders, thereby reducing the labor intensity of on-site operators and improving loading, unloading, and transportation efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
