Description

Technical Field

[0001] The invention relates to the technical field of gas cylinder filling, and in particular to a bulk cell lifting device used for loading and unloading gas cylinders. Background Art

[0002] When companies load and unload gas cylinders, they usually use manual handling to manually unload the cylinders. The gas cylinders are full of gas, and each gas cylinder is heavy and large in size. When the gas cylinders are unloaded from the truck bed of the transport vehicle by manual handling, multiple people are required to cooperate in the operation, which is not only inefficient but also easy to cause injuries to workers. At present, in the intelligent gas filling process, a manipulator is used instead of manual labor to transport the bulk grid together with the gas cylinders therein to a designated location, and then the gas cylinders are taken out and filled with gas. In the prior art, an application with publication number CN214323385U discloses a special robot for grabbing gas cylinders, which realizes the process of taking out and positioning the gas cylinders from the container grid to prepare for filling with gas; but the working conditions of its jaws to clamp the gas cylinders are relatively harsh, and there is currently a need for a lifting device that is convenient for the manipulator to clamp. Summary of the invention

Therefore, the directional words used are used to illustrate rather than limit the invention.

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Embodiment 1: A bulk lifting device for loading and unloading gas cylinders, such as Figure 1-Figure 5As shown, it includes a support plate 4, a bulk grid 2 and a jacking device, the jacking device is buried in the foundation 1, and the jacking device includes a main frame 5. The main frame 5 is provided with four groups of jacking components and four groups of guide components. The guide components are used to assist the lifting of the jacking components. The jacking components include a lifting motor 6 and two screw lifting reducers 12. The output shaft of the lifting motor 6 is connected to the power output shaft hole of the steering box 19. The steering box 19 is a 90-degree one-in and two-out output mode. The output shaft of the steering box 19 is a hollow through hole, and a transmission shaft 20 is provided in the through hole. The two ends of the transmission shaft 20 are respectively connected to a screw lifting reducer 12 through a coupling. The two screw lifting reducers 12 are symmetrically arranged on the left and right, which provides better load balancing and improves the stability and accuracy of the jacking process; the screw lifting reducer 12 includes a wire lever 13, the top of the wire lever 13 passes through the support plate 4 and is connected to the top plate 10; the bottom of the bulk grid 2 is provided with four bottle supporting bottom plates 7, and the four bottle supporting bottom plates 7 are respectively matched with the corresponding two top plates 10. The gas cylinder 3 can be quickly lifted by the lifting assembly, which reduces manual intervention and improves handling efficiency.

[0026] Embodiment 2: A bulk lifting device for loading and unloading gas cylinders, such as Figure 3 As shown, the guide assembly includes a fixed slide rail 16 and a follower slide rail 18. The fixed slide rail 16 is arranged on the main frame 5. The fixed slide rail 16 is slidably connected with a slider Ⅰ15. The slider Ⅰ15 is arranged on a guide plate Ⅰ11. The follower slide rail 18 is fixed on the guide plate Ⅰ11. The top of the guide plate Ⅰ11 is connected to the top plate 10. The follower slide rail 18 is slidably provided with a slider Ⅱ17. The slider Ⅱ17 is fixed on the guide plate Ⅱ, and the guide plate Ⅱ is fixed on the main frame 5. The setting of the guide assembly ensures the stability and safety of the jacking process, and prevents the gas cylinder 3 from tilting or falling during the transportation process.

[0027] like Figure 2 As shown, the screw lift reducer 12 is provided with a dustproof assembly, which includes a dustproof sleeve 8 and a dustproof tube 24. The dustproof tube 24 is sleeved on the lower part of the screw lever 13, and the dustproof sleeve 8 is sleeved on the upper part of the screw lever 13. The dustproof sleeve 8 and the dustproof tube 24 can effectively prevent dust from entering the screw lift reducer 12, reduce the occurrence of faults, and ensure the long-term stable operation of the equipment.

[0028] The dustproof tube 24 is fixed to the main frame 5 by a clamp, and a cleaning port is provided at the bottom end of the dustproof tube 24 to facilitate cleaning of accumulated dust.

[0029] like Figure 4 As shown, the bulk compartment 2 is provided with supporting legs 22 , and the supporting plate 4 is provided with positioning blocks 9 , which cooperate with the supporting legs 22 to limit the position, thereby ensuring the stability of the position of the bulk compartment 2 .

[0030] like Figure 5-Figure 6 As shown, the bulk compartment 2 is provided with a limit plate 21, which is a V-shaped steel plate welded to the frame of the bulk compartment 2; a limit bar 14 is provided on the bottle supporting bottom plate 7, and the limit bar 14 is in contact with and connected to the limit plate 21. The limit bar 14 can be placed on the limit plate 21 to limit the movement of the limit bar 14; the stability of the gas cylinder 3 during the jacking process is ensured, and the lateral movement of the gas cylinder 3 is avoided.

[0031] The support plate 4 is provided with a photoelectric limit sensor 23, which is connected to a controller, and the controller controls the start of the motor; the photoelectric limit sensor 23 ensures the accurate stop position during the lifting process to avoid excessive lifting or position deviation. The rest is the same as in Example 1.

[0032] When the present invention is in operation, taking the first group as an example, the bulk compartment 2 filled with gas cylinders 3 is first placed above the lifting device, and the positioning block 9 is used to limit the position. The lifting motor 6 can be driven by the steering box 19 and the transmission shaft 20, and the two sets of screw lifting reducers 12 are synchronously driven to rise, and the bottle support bottom plate 7 of the first group of gas cylinders 3 in the bulk compartment 2 is automatically lifted, and then the first group of gas cylinders 3 are lifted to a specified height. The photoelectric limit sensor 23 on the support plate 4 is monitored in real time. When the lifting reaches the set height, the photoelectric limit sensor 23 sends a signal, and the lifting motor 6 stops running. In order to prevent the screw of the screw lifting reducer 12 from tilting during the lifting process, the guide assembly assists the screw to run up and down. The lifting motor 6 has a built-in brake system, which can keep the gas cylinder 3 lifted to the set height and keep the position unchanged. This system is a prior art and will not be described in detail here. At this time, the automatic filling manipulator can clamp the gas cylinders 3 that have been lifted into place one by one to the filling station. After the first group of gas cylinders 3 are clamped, the first group of lifting devices automatically descends to the initial lower limit position, and then the second group of lifting motors 6 operate according to the operation mode of the first group of lifting motors 6, and so on, until all gas cylinders 3 are clamped and the last group of bottle supporting bottom plates 7 are reset, and the work is completed. The automatic filling robot is a prior art and will not be described here.

[0033] According to the working characteristics of this device, on the other side where the gas cylinder 3 is filled, the corresponding bulk grid 2 is placed on the lifting device, and then the bottle supporting bottom plate 7 is lifted. After the manipulator fills a group of bottle supporting bottom plates 7 with the filled gas cylinders 3 in sequence, it automatically descends. Then the second group of bottle supporting bottom plates 7 rises, and automatically descends after being full, and so on, to complete the bottling.

[0034] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
