Description

Technical Field

[0001] This utility model relates to the technical field of thermal cutting and welding auxiliary equipment, and in particular to a gas cylinder transport device for thermal cutting and welding operations. Background Technology

[0002] In metallurgical processing, industrial manufacturing, construction, and maintenance, thermal cutting and welding are widely used high-temperature processes. The two commonly used gas combinations in thermal cutting and welding are oxygen and acetylene. Acetylene is a combustible gas that burns in oxygen to produce a high-temperature flame. Acetylene combustion releases a large amount of heat, with flame temperatures reaching over 3000℃, sufficient to rapidly melt and oxidize most metal materials. Oxygen is a combustion-supporting gas; during thermal cutting or welding, it mixes with the combustible gas and burns to produce a high-temperature flame, rapidly heating the metal material to its ignition point and causing a violent oxidation reaction, thus achieving cutting or welding. Both oxygen and acetylene require high-pressure cylinders for storage, and the safe transportation and storage of these cylinders directly affect operational efficiency and personnel safety. Traditional cylinder transportation often relies on simple handcarts or manual handling, lacking securing devices. In bumpy or tilted environments, cylinders are prone to rolling and collisions, leading to valve damage, gas leaks, or even explosions. Therefore, a cylinder transportation device for thermal cutting and welding operations needs to be developed. Utility Model Content

[0003] The purpose of this invention is to provide a gas cylinder transport device for thermal cutting and welding operations, thereby solving the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a gas cylinder transport device for thermal cutting and welding operations, comprising two inverted triangular structures arranged in parallel. The lower ends of the two frames are fixedly connected by a connecting sleeve. An axle is rotatably installed inside the connecting sleeve, and wheels are respectively installed at both ends of the axle. Horizontal support rods are fixedly installed horizontally at opposite sides of the two frames. Gas cylinder racks are fixedly installed at the free ends of the two opposite horizontal support rods. Each gas cylinder rack includes a fixed part and a movable part. The back side of the fixed part is fixedly connected to the two corresponding horizontal support rods. One end of the fixed part and the movable part opposite to each other are hinged by a plurality of evenly spaced hinges, and the other end is provided with a set of multi-phase adaptable buckles.

[0006] Furthermore, each of the gas cylinder racks has a buffer clamping plate with a semi-circular cross-section inside the fixed part and the movable part. Each buffer clamping plate has a plurality of sliding rods fixedly installed on its back side. Each sliding rod slides in cooperation with the corresponding fixed part or movable part and a spring is sleeved on the part between the fixed part or movable part and the buffer clamping plate. One end of each sliding rod away from the corresponding buffer clamping plate extends to the outside of the gas cylinder rack and is fixedly provided with a limiting head.

[0007] Furthermore, two vertical support rods are symmetrically fixedly installed on each of the two vehicle frames, and a fire extinguisher rack for placing fire extinguishers is fixedly installed between the two opposing vertical support rods.

[0008] Furthermore, each of the fire extinguisher racks is fixedly connected to the corresponding two vertical support rods on both sides by two horizontal connecting rods.

[0009] Furthermore, two pairs of mounting plates are symmetrically fixed at both ends of the upper part of the two frames. A drive pulley is rotatably mounted on the outer side of each mounting plate. A drive belt adapted to each of the two drive pulleys on the same frame is provided between them. The two drive pulleys at one end of the two frames are connected by a connecting shaft. A drive motor for driving the corresponding drive pulley to rotate is provided on the inner side of one of the mounting plates at the other end of the two frames. A winch roller is sleeved on the connecting shaft. A sunshade cloth is wound around the winch roller. The free end of the sunshade cloth is fixedly connected to the upper side of the two drive belts.

[0010] Furthermore, a connecting plate is fixedly provided at the free end of the sunshade cloth, and the two ends of the connecting plate are respectively fixedly connected to the upper side of the two transmission belts.

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

[0012] This invention utilizes two frames and wheels to transport gas cylinders used for thermal cutting and welding. The two cylinder frames can hold oxygen and acetylene cylinders respectively. When placing a cylinder, the movable part of the cylinder frame is opened, and the cylinder is placed inside the fixed part. Then, the movable part is closed, and the latches between the movable and fixed parts are locked, thus limiting the cylinder's placement. Furthermore, after the cylinder is placed inside the cylinder frame, the two buffer clamps, under the action of springs, work together to hold the cylinder firmly, further improving the stability of the cylinder placement. Therefore, this invention can prevent the cylinders from tipping over or bumping during transport, achieving safe transportation of the cylinders and reducing safety hazards.

[0020] like Figures 1-5 As shown, a gas cylinder transport device for thermal cutting and welding operations includes two parallel frames 1 arranged in an inverted triangular structure. The lower ends of the two frames 1 are fixedly connected by a connecting sleeve 2. An axle 3 is rotatably mounted inside the connecting sleeve 2, and wheels 4 are respectively mounted at both ends of the axle 3. The overall movement of the two frames 1 is achieved by the rotational movement of the wheels 4 on the ground.

[0021] Two horizontal support rods 5 are fixedly mounted on opposite sides of each of the two opposing horizontal support rods 5. A gas cylinder rack 6 is fixedly mounted on the free end of each pair of opposing horizontal support rods 5. Each gas cylinder rack 6 includes a fixed part 6-1 and a movable part 6-2. The back side of the fixed part 6-1 is fixedly connected to the corresponding two horizontal support rods 5. One end of the fixed part 6-1 and the movable part 6-2 on opposite sides are hinged together by multiple evenly spaced hinges 6-3. A set of multi-phase matching buckles 6-4 is installed between the other ends. When a gas cylinder needs to be placed, the movable part 6-2 of the gas cylinder rack 6 is opened, the gas cylinder is placed inside the fixed part 6-1, and then the movable part 6-2 is closed and the buckles 6-4 between the movable part 6-2 and the fixed part 6-1 are locked, thereby limiting the placement of the gas cylinder. The two gas cylinder racks can hold oxygen cylinders and acetylene cylinders respectively, preventing the cylinders from tipping over or colliding during transport, ensuring safe transport of the gas cylinders and reducing safety hazards.

[0022] Each gas cylinder rack 6 has a semi-circular cross-section buffer clamping piece 6-5 disposed inside the fixed part 6-1 and the movable part 6-2. Multiple sliding rods 6-6 are fixedly mounted radially on the back side of each buffer clamping piece 6-5. Each sliding rod 6-6 slides with a through hole on the corresponding fixed part 6-1 or movable part 6-2, and a spring 6-7 is fitted between the fixed part 6-1 or movable part 6-2 and the buffer clamping piece 6-5. One end of each sliding rod 6-6, away from the corresponding buffer clamping piece 6-5, extends to the outside of the gas cylinder rack 6 and is fixedly mounted with a limiting head 6-8. When a gas cylinder is placed inside the gas cylinder rack, the two buffer clamping pieces together clamp the gas cylinder under the action of the springs, thereby further improving the stability of the gas cylinder placement.

[0023] Two vertical support rods 7 are symmetrically fixedly installed on each of the two vehicle frames 1. A fire extinguisher rack 8 for holding fire extinguishers is fixedly installed between each of the two opposing vertical support rods 7. In this embodiment, each fire extinguisher rack 8 is fixedly connected to the corresponding two vertical support rods 7 on both sides via two horizontal connecting rods 9. By placing fire extinguishers inside the fire extinguisher racks, fire extinguishing operations can be easily carried out in the event of a fire during thermal cutting and welding operations.

[0024] Two pairs of mounting plates 10 are symmetrically fixed at both ends of the upper part of the two frames 1. A drive pulley 11 is rotatably mounted on the outer side of each mounting plate 10. A drive belt 12, adapted to the pulley 11, is installed between the two drive pulleys 11 located on the same frame 1. The two drive pulleys 12 located at one end of the two frames 11 are connected by a connecting shaft 13. A drive motor 14 for driving the corresponding drive pulley 11 is mounted inside one of the mounting plates at the other end of the two frames. A battery (not shown in the figure) for supplying power to the drive motor 14 is mounted inside the other mounting plate. A winch roller 15 is fixedly mounted on the connecting shaft 13. A sunshade cloth 16 is wound around the winch roller 15, and the free end of the sunshade cloth 16 is fixedly connected to the upper side of the two drive belts 12. Specifically, a connecting plate 17 is fixedly mounted on the free end of the sunshade cloth 16, and both ends of the connecting plate 17 are fixedly connected to the upper side of the two drive belts 12. When performing hot cutting or welding operations in the hot summer, the corresponding transmission pulley can be rotated by the drive motor. Under the action of the connecting shaft, the two transmission belts move synchronously. During the operation of the two transmission belts, the sunshade cloth is fully unfolded, thereby meeting the safety requirements for sun protection of gas cylinders during outdoor hot work operations in summer.
