Description

Technical Field

[0001] This utility model relates to a tool for gas welding and gas cutting, specifically a gas hose reeling and releasing device. Background Technology

[0002] In the field of engineering construction, flame cutting and gas welding are two commonly used construction methods, widely applied in the cutting and joining of metal structures. These operations typically require the use of oxygen hoses and acetylene hoses to provide the necessary oxygen and fuel gases. Traditionally, hoses are manually coiled or pulled during use, which easily leads to tangling or crossing of the hoses. This not only increases the labor intensity of operators but also creates a chaotic construction site, severely impacting work efficiency. Furthermore, hoses are easily damaged during improper handling. Utility Model Content

[0003] The purpose of this invention is to provide an air belt take-up and take-down device to solve the problems of low efficiency and easy damage to the air belt in traditional air belt take-up and take-down methods.

[0004] 1. This utility model is implemented as follows: an air belt winding and unwinding device, the structure of which includes a frame, a caster wheel disposed at the lower end of the frame, a bracket disposed on the frame, and an air supply belt winding assembly disposed on the bracket. The air supply belt winding assembly includes a roller disposed on the bracket and a winding ring attached to the outer wall of the roller. A shaft tube is connected to both ends of the roller, and an air supply belt is connected to the inner end of the shaft tube. An opening is provided on the roller for the air supply belt to pass through. The roller can rotate with the rotation of the winding ring for winding or unwinding the air supply belt.

[0005] Furthermore, a right-angle connector is provided at the outer end of each shaft tube, and a shaft seat that mates with it is provided on the bracket.

[0006] Furthermore, there are two tape loops, symmetrically arranged at both ends of the roller.

[0007] Furthermore, a connecting rod is provided on the outer wall of the roller, and the tape is looped around the connecting rod.

[0008] Furthermore, a caster wheel is provided at the lower end of the frame, and a push rod is provided on the frame.

[0009] Furthermore, a hook is provided on the push rod.

[0010] Furthermore, the push rod is located at the front end of the frame, and the bracket is located at the rear end of the frame.

[0011] This invention enables the rapid and safe deployment and retraction of the gas supply belt, making the deployment and retrieval of the gas supply belt more convenient. It not only saves the time required for the deployment and transportation of the gas supply belt, but also improves the overall efficiency of gas welding or cutting work.

[0012] This invention uses a hook to hang the welding or cutting torch, preventing damage or accidental activation of the tool during transport and ensuring the safety of the operator.

[0013] This invention utilizes a right-angle connector to reduce the outward extension length of the air-connecting belt, preventing collisions or scratches with surrounding objects during movement, thereby protecting the air-connecting belt from damage and extending its service life.

[0014] The materials used in this invention are all commonly used in engineering, resulting in low manufacturing costs and reduced maintenance and replacement costs. Furthermore, most components can be reused across different projects, or even recycled, further reducing the overall long-term cost.

[0015] This invention is applicable to various construction sites and industrial environments, especially in complex construction environments with limited space, where it can effectively improve work efficiency and safety. Its simple and practical design makes this device highly valuable for application in similar projects.

[0016] This invention allows the air supply belt to be effectively stored when not in use, reducing the space occupied and keeping the work area clean and orderly. Attached Figure Description

[0020] like Figure 1 and Figure 2 As shown, this utility model includes a frame 1, a bracket 2 mounted on the frame 1, and an air supply belt winding assembly mounted on the bracket 2.

[0021] The air supply belt winding assembly includes a roller 3 mounted on a bracket 2 and a winding ring 4 attached to the roller 3. Rotating the winding ring 4 causes the roller 3 to rotate, winding the air supply belt 5 onto or removing it from the roller 3. A connecting rod 13 is provided on the outer wall of the roller 3, and the winding ring 4 is attached to the connecting rod 13, ensuring it is securely fixed to the roller 3. The roller 3 rotates along with the winding belt 4. There are two winding rings 4, symmetrically arranged at both ends of the roller 3, allowing workers to wind and unwind the air supply belt from both sides of the air supply belt winding device. The winding ring 4 and the connecting rod 13 make it easier for workers to rotate the roller 3, avoiding the laborious operation of directly rotating the roller 3, and also limit the winding range of the air supply belt 5 on the roller 3.

[0022] The frame 1 includes a body frame 1-1 and a base plate 1-2 attached to the lower end of the body frame 1-1. The body frame 1-1 serves as the main supporting structure of the frame, providing strength and stability for the entire vehicle. The base plate 1-2 serves as the supporting surface at the bottom of the vehicle, used for mounting other components or carrying cargo. The support 2 includes two support rods 2-1 and crossbars 2-2 attached to the two support rods 2-1. The two support rods 2-1 are spaced apart, and their upper ends are inclined towards the middle to increase the stability of the support. The two support rods 2-1, the crossbars 2-2, and the base plate 1-2 together form a trapezoidal structure. This trapezoidal structure not only enhances the load-bearing capacity of the support 2 but also provides more connection points and stability. The body frame 1-1 is made of φ14 round steel, and the base plate 1-2 is made of 4mm steel plate. The support 2 is made of the same material as the body frame 1-1.

[0023] Four casters 8 are installed at the lower end of the frame 1, located near the four corners of the frame 1. A push rod 9 is installed on the frame 1, allowing workers to move the frame 1 to the location where welding or cutting operations are required. Hooks 10 are installed on the push rod 9 to hang welding or cutting torches, preventing damage or impact during transport. The push rod 9 is located at the front of the frame 1, while the bracket 2 is located at the rear of the frame 1. The front of the frame 1 can also accommodate oxygen and acetylene cylinders.

[0024] There are two supports 2, arranged in parallel and spaced apart, which together support the lower end of the roller 3. A shaft tube 6 is threaded through both ends of the roller 3, and an air supply belt 5 is connected to the inner end of each shaft tube 6. Both air supply belts 5 are connected to welding torches (not shown). An opening is provided on the roller 3 for the air supply belts 5 to enter and exit.

[0025] Each end of the shaft tube 6 is connected to a gas inlet strap 14. Two gas inlet straps 14 are connected to gas cylinders (not shown), one for oxygen and the other for acetylene. A direct connector 11 is located at the inner end of the shaft tube 6, and the gas supply strap 5 is connected to the direct connector 11 via a clamp. A right-angle connector 12 is located at the outer end of the shaft tube 6, and the gas inlet strap 14 is connected to the right-angle connector 12 via a clamp. A shaft seat 7 that mates with the right-angle connector 12 is provided on the support 2. The right-angle connector 12 reduces the outward extension length of the gas inlet strap, preventing it from colliding with surrounding objects during transport and causing damage or detachment. In this embodiment, the shaft seat 7 is an L50 angle steel with a notch for mates with the right-angle connector 12.

[0026] When using the air supply belt 5, rotate the belt reel 4 to drive the roller 3 to rotate, thereby releasing the two air supply belts 5. After use, rotate the belt reel 4 in the opposite direction to retract the two air supply belts 5 and wrap them around the roller 3.
