Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a cylinder lifting device. Background Art

[0002] Lifting cylinders are widely used in various mechanical industrial automation production lines and manufacturing processes, such as automatic loading and unloading devices, automatic packaging equipment, conveyors, material storage shelves, lathes, drilling machines, punching machines and other machine tools. Its advantages are high conveying distance accuracy, strong working reliability, fast action speed, simple operation, long service life, and can be positioned as needed.

[0003] However, the conveying distance of the existing cylinder lifting device is directly related to the maximum moving distance of the cylinder telescopic rod or the moving module, that is, the maximum moving distance of the cylinder's output end is the maximum lifting distance of the cylinder lifting device, which directly leads to the lifting device occupying a large working space. Based on this, a cylinder lifting device that can solve the above problems is proposed. Summary of the Utility Model

[0004] To solve the technical problem of the cylinder lifting device occupying space, the utility model provides a cylinder lifting device.

[0005] The utility model is realized by the following technical solutions: A cylinder lifting device includes a mounting plate, a plurality of sprockets, a plurality of chains and a plurality of hooks. One side of the mounting plate is fixedly connected to one end of each of the plurality of chains respectively, and the other end of each of the plurality of chains is fixedly connected to one of the plurality of hooks one-to-one. One side of each of the plurality of chains is arranged in one-to-one cooperation with one of the plurality of sprockets. A boom-type bracket mechanism for facilitating the placement of lifting is arranged on one side of the mounting plate, and a cylinder pushing mechanism for moving the sprocket up and down is arranged below the sprocket.

[0006] As a further improvement of the above solution, the boom-type bracket mechanism includes a boom-type support plate and a lifting platform. One side of the mounting plate is fixedly connected to a plurality of the boom-type support plates, and the upper sides of the plurality of the boom-type support plates are fixedly connected to the lower side of the lifting platform together. A protective frame assembly for preventing foreign objects from entering the interior of the cylinder lifting device is arranged on the outer side of the lifting platform. A slide rail mechanism for limiting the up and down movement of the mounting plate is arranged on one side of the mounting plate, and a limiting slide bar mechanism for maintaining the mechanical balance of the mounting plate is arranged on the other side of the mounting plate.

[0007] As a further improvement of the above solution, the protective frame assembly includes a reinforcing plate, a box body and a load-bearing frame. The reinforcing plate is arranged on the bottom side inside the box body, the upper side of the reinforcing plate is fixedly connected to the lower side of the load-bearing frame, and the upper side of the reinforcing plate is fixedly connected to the lower side of the hook.

[0008] As a further improvement of the above solution, the slide rail mechanism includes a plurality of slide rails and a plurality of sliders. The plurality of slide rails are respectively fixedly connected to the inner side of the load-bearing frame. One side of each slide rail is simultaneously slidably connected to the plurality of sliders, and one side of the plurality of sliders is simultaneously fixedly connected to the mounting plate.

[0009] As a further improvement of the above solution, the limit slide bar mechanism includes a plurality of limit bars and a plurality of limit sleeves. The plurality of limit bars are respectively fixedly installed on the upper side of the reinforcing plate. Each limit bar is simultaneously slidably connected to the plurality of limit sleeves, and one side of the plurality of limit sleeves is simultaneously fixedly connected to one side of the mounting plate.

[0010] As a further improvement of the above solution, the cylinder pushing mechanism includes a cylinder and a mounting block. The output end of the cylinder is fixedly connected to the lower side of the mounting block. A transmission rod is rotatably connected to the mounting block, and the plurality of sprockets are simultaneously fixedly connected to the transmission rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model cooperates with each other through the cylinder pushing mechanism, sprockets and chains, and adopts the principle of a hanging pulley. For the output end of the cylinder with the same stroke, under the action of the sprockets and chains, the moving distance of one end of the chain can be magnified. Therefore, when the lifting height of the lifting device is certain, by using this method of pulling the mounting plate with the chain, the moving space of the output end of the cylinder can be significantly reduced, and the occupied space of the cylinder can be reduced.

[0013] 2. The present utility model cooperates with each other through the sprockets, chains and the mounting plate. According to the principle of the hanging pulley, the speed of the mounting plate during lifting, that is, the speed of the upper end of the chain, is much greater than the speed of the output end of the cylinder. For the same lifting distance, the lifting and lowering speed of the cylinder lifting device of the present utility model is faster. Brief Description of the Drawings

[0020] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0021] Embodiment:

[0022] Please refer to Figures 1 - 4 , a cylinder lifting device of this embodiment includes a mounting plate 8, two sprockets 12, two chains 9 and two hooks 15. One side of the mounting plate 8 is fixedly connected to one end of the two chains 9 respectively. The other ends of the two chains 9 are fixedly connected to the two hooks 15 one by one. One side of the two chains 9 is arranged in one-to-one cooperation with the two sprockets 12. A boom-type bracket mechanism for facilitating the placement of lifting and lowering is arranged on one side of the mounting plate 8. A cylinder pushing mechanism for moving the sprocket 12 up and down is arranged below the sprocket 12.

[0023] A structure system similar to a hanging pulley is built through the chain 9 and the sprocket 12 to realize the conversion of force, lifting distance and lifting time.

[0024] Please refer to Figure 3 As shown, the boom-type bracket mechanism includes a boom-type pallet 13 and a lifting platform 2. One side of the mounting plate 8 is fixedly connected to the two boom-type pallets 13. The upper sides of the two boom-type pallets 13 are fixedly connected to the lower side of the lifting platform 2 together. A protective frame assembly for preventing foreign objects from entering the inside of the cylinder lifting device is arranged on the outside of the lifting platform 2. A slide rail mechanism for limiting the up and down movement of the mounting plate 8 is arranged on one side of the mounting plate 8. A limit slide rod mechanism for maintaining the mechanical balance of the mounting plate 8 is arranged on the other side of the mounting plate 8.

[0025] Please refer to Figure 2 As shown, the protective frame assembly includes a reinforcing plate 10, a box body 1 and a load-bearing frame 3. The load-bearing frame 3 is a square frame structure. The reinforcing plate 10 is arranged on the inner bottom side of the box body 1. The upper side of the reinforcing plate 10 is fixedly connected to the lower side of the load-bearing frame 3. The upper side of the reinforcing plate 10 is fixedly connected to the lower side of the hook 15.

[0026] Please refer to Figure 4As shown in the figure, the slide rail mechanism includes two slide rails 4 and four sliders 14. The two slide rails 4 are respectively fixedly connected to the inner side of the load-bearing frame 3. One side of each slide rail 4 is slidably connected to the two sliders 14 at the same time. One side of the four sliders 14 is fixedly connected to the mounting plate 8 at the same time. By setting the slide rails 4 and the sliders 14, the smoothness of the up and down movement of the mounting plate 8 is increased.

[0027] Please refer to Figure 4 As shown in the figure, the limit slide bar mechanism includes two limit bars 7 and four limit sleeves 6. The two limit bars 7 are respectively fixedly installed on the upper side of the reinforcement plate 10. Each limit bar 7 is slidably connected to the two limit sleeves 6 at the same time. One side of the four limit sleeves 6 is fixedly connected to one side of the mounting plate 8 at the same time. Since the lifting platform 2 adopts the load-bearing force mode of the support arm, at this time, the mounting plate 8 has a tendency to tilt to one side. In order to increase the shear resistance of the load-bearing frame 3 and solve the mechanical balance problem during the up and down movement of the mounting plate 8, it can be achieved by setting the limit bars 7.

[0028] Please refer to Figure 4 As shown in the figure, the air cylinder pushing mechanism includes an air cylinder 5 and a mounting block 11. The output end of the air cylinder 5 is fixedly connected to the lower side of the mounting block 11. A transmission rod is rotatably connected to the mounting block 11. A plurality of sprockets 12 are fixedly connected to the transmission rod at the same time.

[0029] The implementation principle of a cylinder lifting device in the embodiment of the present application is as follows: When the air cylinder 5 is started, its output end pushes the mounting block 11 to rise. Since one end of the chain 9 is fixedly connected to the hook 15, when the sprocket 12 moves upward together with the mounting block 11, it can push the other end of the chain 9 to rise, pulling the mounting plate 8 to move upward. The limit sleeve 6 slides upward along the limit bar 7, and the slider 14 on the other side moves upward along the slide rail 14. At the same time, the mounting plate 8 directly drives the lifting platform 2 of the boom type support plate 13 to move upward.

[0030] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
