Technical Field

[0001] The utility model belongs to the field of steel cylinder conveying equipment, in particular to a semi-automatic loading and unloading steel cylinder cart. Background Art

[0002] Industrial sites often use cylinders for storing industrial gases like oxygen and acetylene. Loading and unloading these cylinders typically requires a cylinder cart. Loading the cylinders onto a conventional cart is time-consuming and labor-intensive due to the heavy weight of the cylinders. Therefore, operators must roll the cylinders onto the cart. However, this method increases the operator's workload and can lead to injuries from accidentally dropping the cylinders while rolling. Furthermore, some operators, seeking to save time, simply lay the cylinders on the ground and roll them, increasing damage and safety risks. Utility Model Content

[0020] The structure and working principle of the semi-automatic loading and unloading cylinder trolley device of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-2 As shown, a semi-automatic loading and unloading double cylinder cart is taken as an example, which includes a cart body 1, a magnet 2, a magnet manual release device 3 and a storage rack 4;

[0022] The cart body 1 is configured to carry two cylinders at the same time to increase handling efficiency. The cart body 1 includes longitudinally arranged support rods 1-7 at both ends, with an isolation support rod 1-8 disposed between the support rods 1-7. A handle 1-1 is disposed on the top of the support rod 1-7, and comb-shaped fork tines 1-3 are disposed at the bottom of the support rod 1-7 and the isolation support rod 1-8 to support the cylinders at the bottom. First rollers 1-4 are disposed on both sides of the fork tines 1-3. Second rollers 1-5 and third rollers 1-6 are disposed sequentially on the side of the fork tines 1-3 away from the forward direction of the cart. The diameters of the first rollers 1-4, the second rollers 1-5, and the third rollers 1-6 increase in size to enable the cart to move in loading and unloading positions and in moving positions. When the fork tines 1-3 at the bottom of the cart are level with the ground, the cart is in a loading and unloading position, with the first rollers 1-4 and the second rollers 1-5 touching the ground and the third roller 1-6 suspended in the air. When the fork 1-3 is in an inclined state, and the first roller 1-4 is suspended in the air, and the second roller 1-5 and the third roller 1-6 are on the ground, the fork is in a moving state. Due to carrying two cylinders at the same time, three groups of arc support plates 1-2 are provided between the isolation support rod 1-8 and the support rods 1-7 at both ends, namely, upper, middle and lower groups.

[0023] The magnet 2 is mounted on the arc support plate 1-2. The side of the magnet 2 close to the cylinder is arc-shaped and is used to absorb the cylinder. A magnet manual release device 3 is installed on the other side of the magnet 2. Each cylinder station is provided with a set of magnets 2 and a magnet manual release device 3.

[0024] The storage rack 4 is a unified storage place for steel cylinders, and the length of the storage rack d can be adjusted according to the number of steel cylinders to be stored; the bottom is a comb-tooth structure with a spacing equivalent to that of the fork teeth 1-3, and the top of the storage rack 4 is an arc groove, and each steel cylinder corresponds to a slot.

[0025] Specifically, the second roller 1-5 is connected to the fork 1-3 through the first roller bracket 1-9, the third roller 1-6 is connected to the first roller bracket 1-9 through the second roller bracket 1-10, and the second roller bracket 1-10 is arranged at an angle.

[0026] Specifically, the distance between the isolation support rod 1-8 and the two end support rods 1-7 is equivalent to the diameter of the steel cylinder. Similarly, the diameter of the arc support plate 1-2 is equivalent to the diameter of the steel cylinder.

[0027] Specifically, the manual magnet release mechanism 3 is a conventional push-type release mechanism. The operator simply grasps the handle of the manual magnet release mechanism 3 and presses it firmly, pushing out the push rod on the upper portion of the mechanism 3 and pushing the cylinder away from the magnet 2 to release the cylinder. Each cylinder station is equipped with a set of manual magnet release mechanisms 3, which the operator can hold with both hands.

[0028] The operating principle of the device is:

[0029] When a cylinder is placed on storage rack 4 and needs to be removed, the cart is first adjusted to a loading and unloading position, with the tines 1-3 parallel to the ground. The cart is then moved by the first and second rollers 1-4 and 1-5 below the main body 1, with the third roller 1-6 suspended in the air. Manual adjustment is then performed to align the tines 1-3 on the cart with the gaps between the comb teeth on the storage rack 4. The cart is then manually pushed into the storage rack 4 until the magnet 2 on the circular support plate 1-2 makes contact with the cylinder. The magnet 2 magnetically attracts the cylinder, and the tines 1-3 rest on the bottom of the cylinder. The operator then depresses the handle 1-1 on the main body 1 to tilt the cart into a moving position. During this tilting process, the tines 1-3 pass through the corresponding comb teeth on the storage rack 4, tilting synchronously with the cart. Together with the magnet 2, they also tilt the cylinder with the cart. When the cart is tilted to a moving posture, the first rollers 1-4 of the cart body 1 are suspended in the air, and the second rollers 1-5 and the third rollers 1-6 are on the ground, thereby achieving movement in a moving posture.

[0030] When it is necessary to place the cylinders on the cart onto the storage rack 4, the above steps are simply reversed, the forks 1-3 are aligned with the comb teeth gaps on the storage rack 4, the cart is manually pushed into the storage rack 4, and the handle 1-1 on the cart body 1 is lifted to convert the cart from the tilted moving posture to the horizontal loading and unloading posture. During the conversion process, the forks 1-3 pass downward through the comb teeth gaps on the storage rack 4, thereby retaining the cylinders on the comb teeth of the storage rack 4. When the cart is fully in the horizontal loading and unloading posture, the manual release device of the magnet 2 is manually pressed to disengage the cylinder and the magnet 2, and the manual release device of the magnet 2 is simultaneously pulled backward to move the empty cylinder cart out of the storage rack 4, thus completing the cylinder placement operation.

[0031] During the use of the semi-automatic loading and unloading cylinder trolley, there is no need to manually carry the cylinders, and there is no need to perform heavy physical labor. The operator only needs to push the trolley and operate the magnetic manual release device 3, which greatly reduces the labor intensity of the operator; and the left and right hands can be operated at the same time to load and unload two cylinders at the same time, which increases the efficiency of cylinder loading and unloading; the operator does not directly contact the cylinders, which avoids safety hazards when moving the cylinders, and also plays a certain protective role for the cylinders.
