Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to welding equipment for steel structure engineering. Background Art

[0002] Steel structures are primarily constructed of steel and are one of the main types of building structures. During steel construction, steel components are typically connected using the following methods: riveting, welding, a combination of riveting and welding, and bolting. Bolting is the most common method, followed by welding.

[0003] Electric welding is the most common method for welding steel structures. However, electric welding requires power, necessitating the pre-installation of power cables. This, combined with the complex construction environment and the need for safety measures, can negatively impact construction efficiency. Furthermore, when working at height, the welding gun and welding machine are often located far apart, necessitating cable management during the welding process to prevent them from becoming entangled in the steel structure, further reducing welding efficiency. Summary of the Invention

[0004] To address the above-mentioned issues, the present invention discloses welding equipment for steel structure engineering, comprising a housing, wherein a bottle storage chamber and a storage chamber are provided within the housing. The housing comprises two bottle storage chambers, each housing a gas cylinder. A collar is fixedly connected to the inner sidewall of the bottle storage chamber, and a support is threadedly connected to the bottom of the bottle storage chamber. The gas cylinder is placed in the middle of the upper end of the support, and the collar engages the upper sidewall of the gas cylinder. Two bottle storage chambers are provided, one for storing combustible gas and the other for storing combustion aid, and the two bottle storage chambers are separated to improve storage safety.

[0005] The storage chamber is provided with a valve body, which is exposed from the upper portion of the housing. A valve stem extends from the upper end of the valve body, and a regular polygonal inner wall is provided around the valve stem. The lower portion of the valve is sleeved on the valve stem, and the side walls of the lower portion of the valve cooperate with the regular polygonal inner wall. The upper end of the valve stem is fixedly connected to a baffle. A spring is sleeved on the valve stem, and the upper end of the spring abuts the baffle, while the lower end of the spring abuts the lower portion of the valve, maintaining the side walls of the lower portion of the valve in a cooperative state with the regular polygonal inner wall. The cooperation between the lower portion of the valve and the regular polygonal inner wall prevents accidental rotation and ensures operational safety. A pressure gauge can be provided on the upper end surface of the housing to facilitate checking the pressure of the delivered gas.

[0006] Preferably, the upper end of the valve lower portion is fixedly connected to the valve upper portion, and the upper end of the housing is provided with a groove, into which both the valve lower portion and the valve upper portion are embedded. That is, under the action of the spring, the valve lower portion and the valve upper portion are in a stored state. When the valve body needs to be opened or closed, the valve upper portion needs to be lifted to disengage the valve lower portion from the inner wall of the regular polygon, and the valve lower portion and the valve upper portion can then be rotated.

[0007] Preferably, a handle is fixedly connected to the middle of the upper end of the box, and a hook is fixedly connected to the back side wall of the box. The handle is convenient for picking up the device, and the hook is used to hang it on the steel structure.

[0008] Preferably, a lower air hole is provided at the bottom of one of the cylinder chambers, and an upper end of the other cylinder chamber is fixedly connected to an upper air hole. The device uses acetylene as the combustible gas, and a cylinder filled with acetylene can be placed in the cylinder chamber with the upper air hole. Oxygen is used as a combustion aid, and a cylinder filled with oxygen is placed in the cylinder chamber. In the event of a slight leak, the oxygen can be quickly and automatically discharged.

[0009] Preferably, a winding roller is provided inside the storage chamber, on which an air tube is wound and bundled, and there are two air tubes, both ends of which are connected to a welding gun, so as to facilitate storage and facilitate the use and transportation of the equipment.

[0010] Preferably, a second door is rotatably connected to one side of the box body, and the second door is connected to the storage chamber, and a first door is rotatably connected to the front side of the box body, and the first door is connected to the bottle storage chamber.

[0011] Preferably, a connecting pipe connected to the gas cylinder is provided on the upper portion of the cylinder storage chamber, and the connecting pipe is communicated with the air pipe to realize gas supply from the gas cylinder.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. Gas welding is more convenient than electric welding. The gas used for gas welding is stored in a box, and the box is easy to carry. It can be hung on the steel structure during operation, which is conducive to welding operations, especially high-altitude operations.

[0014] 2. A valve body is provided, and the upper and lower parts of the valve are arranged to be converged. Further, through a spring, a regular polygonal inner wall, etc., the upper and lower parts of the valve can be prevented from accidentally rotating, thereby greatly improving the safety of the equipment.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively. Example

[0022] Combine Figure 1 and Figure 4 As shown, a welding device for steel structure engineering includes a box body 3, which is a rectangular parallelepiped structure and has a size that is convenient for carrying. A bottle storage chamber 5 and a storage chamber 11 are provided inside the box body 3. There are two bottle storage chambers 5, and a gas cylinder 4 is provided in the bottle storage chamber 5. The two gas cylinders 4 store combustible gas and combustion-supporting agent respectively. The separation can improve the safety of storage. The inner side wall of the bottle storage chamber 5 is fixedly connected with a collar 22, and the bottom of the bottle storage chamber 5 is threadedly connected with a support member 20. The support member 2 0 is provided with a structure for rotating the support 20 at the bottom. The gas cylinder 4 is placed in the middle of the upper end of the support 20. The collar 22 buckles the upper side wall of the gas cylinder 4. The collar 22 is a circular structure. When placing the gas cylinder 4, the upper part of the gas cylinder 4 needs to be inserted into the collar 22 from below, and then the bottom of the gas cylinder 4 is placed on the support 20. Then, the support 20 is rotated from the bottom, and the support 20 rises, thereby tightly clamping the gas cylinder 4 between the support 20 and the collar 22, thereby fixing the gas cylinder 44.

[0023] Combine Figure 1 and Figure 3As shown, a valve body 8 is provided inside the storage chamber 11. There are two valve bodies 8, which respectively control the release of two gases, and the valve bodies 8 are exposed from the upper part of the box body 3. A valve stem 16 is extended from the upper end of the valve body 8. A regular polygonal inner wall 15 is provided around the valve stem 16. A valve lower part 18 is sleeved on the valve stem 16. The side wall of the valve lower part 18 cooperates with the regular polygonal inner wall 15. When the valve lower part 18 cooperates with the regular polygonal inner wall 15, the valve lower part 18 cannot rotate, that is, the valve 8 is locked, achieving the above effect. The shape of the regular polygonal inner wall 15 can be further Changes can be made, for example, by changing it to a tooth-shaped structure, or after the two are matched, by setting resistance, such as increasing friction, to prevent the lower part 18 of the valve from rotating. The upper end of the valve stem 16 is fixedly connected to the baffle 17, and the valve stem 16 is sleeved with a spring 14, and the upper end of the spring 14 is against the baffle 17, and the lower end of the spring 14 is against the valve lower part 18, maintaining the side wall of the valve lower part 18 and the regular polygonal inner wall 15 in a matched state. During installation, the spring 14 is in a pre-tightened state, that is, only under the action of the spring 14, the valve lower part 18 and the regular polygonal inner wall 15 are matched.

[0024] The upper end of the valve lower portion 18 is fixedly connected to the valve upper portion 13. A groove is provided at the upper end of the housing 3, and both the valve lower portion 18 and the valve upper portion 13 fit into the groove. This ensures that the valve upper portion 13 does not protrude from the upper end surface of the housing 3. Viewed horizontally, the valve upper portion 13 has a "T" shape, making it easy to lift and rotate.

[0025] like Figure 2 As shown, a handle 7 is fixedly connected to the middle of the upper end of the box body 3 for lifting the equipment and transferring it during the welding process of the steel structure. A hook 9 is fixedly connected to the back side wall of the box body 3. During welding operations, it can be hung on the steel structure through the hook 9 for easy fixation.

[0026] like Figure 4 As shown, a lower air hole 19 is provided at the bottom of one of the storage chambers 5. The storage chamber 5 is used to store an oxidant, and the selected oxidant is oxygen, and the relative molecular mass of oxygen is greater than the average relative mass of air. Under natural circumstances, oxygen sinks in the air. The upper end of the other storage chamber 5 is fixedly connected to the upper air hole 23. The storage chamber 5 is used to store combustible gas, and the selected combustible gas is acetylene. The relative molecular mass of acetylene is less than the average relative mass of air. Under natural circumstances, acetylene floats in the air. Therefore, in the case of a trace leakage, the two gases are discharged in different directions, which can improve the safety of the equipment.

[0027] like Figure 2As shown, a winding roller 12 is provided inside the storage chamber 11, and an air pipe 2 is wound and bundled on the winding roller 12. The winding roller 12 is used to bundle the air pipe 2, which is convenient for organizing and storing the air pipe 2. At the same time, a space for storing welding rods can be set at the lower part of the storage chamber 11. There are two air pipes 2, which supply two gases respectively, and their ends are connected to a welding gun 1 for welding.

[0028] Combine Figure 1 and Figure 2 As shown, one side of the box body 3 is rotatably connected to a second box door 10, and the second box door 10 is connected to the storage chamber 11. The second box door 10 is opened for taking and placing the welding gun 1. The front of the box body 3 is rotatably connected to a first box door 6, and the first box door 6 is connected to the bottle storage chamber 5. The first box door 6 is opened for replacing the gas cylinder 4.

[0029] like Figure 4 As shown, a connecting pipe 21 connected to the gas cylinder 4 is provided on the upper part of the cylinder chamber 5, and the connecting pipe 21 is communicated with the air pipe 2, that is, the connecting pipe 21 is connected to the gas cylinder 4. At the same time, a valve is also provided on the gas cylinder 4. After the valve is opened, the gas in the gas cylinder 4 is sent out through the connecting pipe 21.
