Description

Technical Field

[0001] This utility model relates to the field of handling device technology, specifically a cylinder handling device that is easy to fix. Background Technology

[0002] A steel cylinder is a type of steel container used to store various high-purity gases such as liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, carbon monoxide, welding shielding gases, laser gases, electric light source gases, and medical gases. These cylinders are relatively heavy and require a trolley for transport.

[0003] Chinese Patent (Authorization Announcement No.: CN 209351438 U, Authorization Announcement Date: 2019.09.06) discloses a cylinder handling trolley. The cylinder support includes a first support rod and a second support rod that are parallel to each other. The first and second support rods are respectively provided with a first sliding groove and a second sliding groove arranged along their extension directions. The bottom end of a first sliding block is engaged with the first sliding groove and slides reciprocally along it. The bottom end of a second sliding block is engaged with the second sliding groove and slides reciprocally along it. A reverse-arc-shaped guard plate is connected between the first and second sliding blocks and can slide synchronously with them along the first and second sliding grooves. At least two locking mechanisms are respectively provided on the first and second support rods. The cylinder handling trolley provided by this utility model provides safe and stable placement of cylinders, convenient handling, and can prevent cylinders from shaking or tipping over.

[0004] While the aforementioned devices can secure the cylinders during transport to prevent them from shaking or tipping over, they reduce transport efficiency. Furthermore, manually carrying heavy cylinders onto vehicles can easily lead to safety accidents due to the lack of a securing mechanism. Therefore, we propose a cylinder transport device that facilitates securing the cylinders. Utility Model Content

[0026] 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 protection scope of the present utility model.

[0027] Please see Figure 1-6This utility model provides a technical solution: a cylinder handling device that is easy to fix, including a power box 1, a rotating rod 24 rotatably passing between the front and rear sides of the power box 1, and rear wheels 4 fixedly connected to the front and rear ends of the rotating rod 24. A drive assembly is installed inside the power box 1. Mounting plates 2 are fixedly installed on the front and rear sides of the left side of the power box 1. Front wheels 15 are provided on the left side of the two mounting plates 2 away from the power box 1. A shock-absorbing assembly is installed between the mounting plates 2 and the front wheels 15. Mounting frames 13 are rotatably installed on the left side of the two mounting plates 2 near the power box 1. Several arc-shaped guard plates 8 are fixedly installed between the two mounting frames 13. Several clamping assemblies are installed on the two mounting frames 13. A lifting and lowering assembly is provided in the middle of the right side of the mounting frame 13. A lifting assembly is also provided at the bottom right side of the mounting frame 13.

[0028] This easy-to-secure cylinder handling device, when handling cylinders, pushes the trolley towards the cylinder, inserts the support plate 12 into the bottom of the cylinder, and simultaneously clamps the cylinder with several clamping components to prevent it from tipping over until the support plate 12 is fully inserted into the bottom of the cylinder. The cylinder is then clamped onto the arc-shaped protective plate 8 by the clamping components, and then the cylinder is lifted by the lifting component and tilted onto the arc-shaped protective plate 8 by the lowering component. This device achieves automatic cylinder loading and unloading, and good fixation of the cylinder during transportation to prevent shaking. The drive component installed inside the power box 1 provides power to the rear wheel 4, and the electric assistance avoids the time and effort required for manual pushing, reducing labor intensity and improving transportation efficiency. A shock-absorbing component is installed between the mounting plate 12 and the front wheel 15 to prevent the front wheel 15 from causing the cylinder to shake significantly and break when encountering potholes during transportation.

[0029] The lifting and lowering assembly includes an electric push rod 6, a mounting bracket 3 is fixedly installed between two sets of mounting plates 1 2, the bottom end of the electric push rod 6 is hinged to the mounting bracket 1 3, a fixing plate 7 is fixedly connected to the side of each of the two sets of mounting brackets 1 ...

[0030] The electric push rod 6 pushes or pulls the rotating sleeve 20, causing the bottom end of the electric push rod 6 to rotate on the mounting bracket 3. Since the rotating sleeve 20 is rotated and mounted on the fixed rod 19, it drives the two sets of mounting plates 2 to rotate.

[0031] The drive assembly includes a drive motor 37, which is fixedly mounted on the bottom inside the power box 1. A gear 38 is fixedly connected to the output shaft of the drive motor 37. A gear 41 is fixedly sleeved on the rotating rod 24. A mounting plate 42 is fixedly connected to the bottom inside the power box 1. A rotating rod 43 is rotatably inserted between the mounting plate 42 and the rear inner wall of the power box 1. A gear 29 and a gear 30 are fixedly sleeved on the rotating rod 43. Gear 1 38 meshes with gear 2 39, and gear 3 40 meshes with gear 41.

[0032] The drive motor 37 rotates gear 38. Since gear 38 meshes with gear 39, gear 39 rotates. Since gear 39 and gear 40 are coaxial, gear 40 rotates, which in turn rotates gear 41, which meshes with gear 40. This, in turn, rotates rotating rod 24. The diameter of gear 38 is smaller than that of gear 39, and the diameter of gear 40 is smaller than that of gear 41. This reduces the speed of the drive motor 37 driving rotating rod 24 and increases the torque. This protects the motor when transporting heavy cylinders and prevents the speed from being too high, thus avoiding accidents to the trolley.

[0033] The shock absorption assembly includes mounting plate 33, which is fixedly connected to the side of mounting plate 2 away from the power box 1. A sliding rod 32 is fixedly inserted into mounting plate 33. A fixed rod 31 is rotatably inserted into the front wheel 15. A sliding sleeve 35 is fixedly connected to the end of the fixed rod 31 near the sliding rod 32. The sliding sleeve 35 is movably sleeved on the sliding rod 32. A spring 34 is provided between the top side of the sliding sleeve 35 and the bottom side of mounting plate 33, and the spring 34 is sleeved on the sliding rod 32. A limit plate 36 is fixedly connected to the bottom end of the sliding rod 32.

[0034] During the transport of the gas cylinder, the front wheel 15 rotates on the fixed rod 31. When the front wheel 15 encounters a pothole, the front wheel 15 bounces, causing the sliding sleeve 35 to bounce. The spring 34 buffers and dampens the bounce of the sliding sleeve 35.

[0035] The clamping assembly includes a clamping plate 9. Several mounting brackets 17 are fixedly connected to the side of the mounting bracket 13 near the mounting plate 2. A rotating rod 18 is rotatably passed through the mounting bracket 17. The clamping plate 9 is fixedly sleeved on the rotating rod 18. A drive motor 16 is fixedly installed on the bottom side of the mounting bracket 17. The bottom end of the rotating rod 18 is fixedly connected to the output shaft end of the drive motor 16.

[0036] The rotating rod 18 is rotated by the drive motor 16, which in turn drives the clamping plate 9 to rotate and clamp the gas cylinder.

[0037] The lifting assembly includes a mounting frame 11. The front and rear left sides of the mounting frame 11 are fixedly connected to the right sides of two sets of mounting brackets 13. A drive motor 25 is fixedly mounted on the right side of the mounting frame 11. Two sets of mounting plates 29 are also fixedly connected to the rear side of the mounting frame 11. A screw 30 is rotatably inserted between the two sets of mounting plates 29. The top end of the screw 30 is fixedly connected to the output shaft end of the drive motor 25. Slide grooves 26 are provided on the front and rear right sides of the mounting frame 11. A sliding plate 27 is threaded onto the screw 30. The front and rear ends of the sliding plate 27 are slidably connected to the two sets of slide grooves 26. A connecting rod 28 is fixedly connected to the bottom side of the sliding plate 27. A support plate 12 is fixedly connected to the bottom end of the connecting rod 28.

[0038] The drive motor 25 rotates the screw 30, causing the sliding plate 27 threaded on the screw 30 to rise. The front and rear ends of the sliding plate 27 slide on the slide groove 26 for limiting. The rise of the sliding plate 27 drives the support plate 12 fixedly connected by the connecting rod 28 to rise.

[0039] A handle 5 is fixedly installed on the top right side of the power box 1 to facilitate the pushing of the trolley.

[0040] Both sets of mounting brackets 13 have baffles 14 fixedly connected to the bottom of the side of the mounting plate 2, which helps to limit the tilting of the mounting brackets 13 and reduce the pressure on the electric push rod 6.

[0041] The clamping plate 9 has several anti-slip textures 10 to prevent slippage during clamping.

[0042] A controller 22 is fixedly installed on the bottom side of the inside of the power box 1 to control each power mechanism.

[0043] A battery 23 is also fixedly installed on the bottom side of the inside of the power box 1 to supply power to each power mechanism. A charging interface 21 is provided on the bottom right side of the power box 1 to charge the battery 23.

[0044] Working principle: This easy-to-fix gas cylinder handling device works as follows: When handling a gas cylinder, the trolley is pushed towards the cylinder, the support plate 12 is inserted into the bottom of the cylinder, and simultaneously, the drive motor 16 rotates the rotating rod 18, which in turn drives the clamping plate 9 to rotate and clamp the cylinder to prevent it from tipping over. This continues until the support plate 12 is fully inserted into the bottom of the cylinder, causing the clamping plate 9 to clamp the cylinder onto the arc-shaped protective plate 8. Then, the drive motor 25 rotates the screw 30, causing the sliding plate 27, which is threaded onto the screw 30, to rise. The front and rear ends of the sliding plate 27 are... The cylinder is lifted by sliding on the chute 26 for limiting, and the rising of the sliding plate 27 drives the support plate 12, which is fixedly connected by the connecting rod 28, to rise. Then, the electric push rod 6 pushes or pulls the rotating sleeve 20, causing the bottom end of the electric push rod 6 to rotate on the mounting frame 3. Since the rotating sleeve 20 is rotated and fitted onto the fixed rod 19, it drives the two sets of mounting plates 2 to rotate, tilting the cylinder onto the arc-shaped protective plate 8. This device achieves automatic loading and unloading of cylinders and good fixation of cylinders during transportation, preventing shaking. Inside the power box 1, drive motor 37 rotates gear 1 38. Since gear 1 38 meshes with gear 2 39, gear 2 39 rotates. Because gear 2 39 and gear 3 40 are coaxial, gear 3 40 rotates, which in turn rotates gear 41, which meshes with gear 3 40. Finally, rotating rod 24 rotates, providing power to the rear wheel 4. Electric assistance avoids the time and effort required for manual pushing, reducing labor intensity and improving transportation efficiency. Furthermore, the diameter of gear 1 38 is smaller than that of gear 2 39. 9. The diameter of gear 3 40 is smaller than that of gear 41, which reduces the speed of drive motor 3 37 driving rotating rod 24 and increases the torque. This protects the motor when transporting heavy cylinders and prevents the speed from being too fast, thus avoiding accidents. A shock-absorbing component is installed between mounting plate 1 2 and front wheel 15. When transporting cylinders, front wheel 15 rotates on fixed rod 2 31. When front wheel 15 encounters potholes, it bounces, causing sliding sleeve 35 to bounce. Spring 34 buffers and dampens the bounce of sliding sleeve 35.
