[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] like Figure 1-5 As shown, the utility model discloses a welding fixing device for adjusting an angle, comprising a main frame 1, a clamping member 2 and a measuring member 3;

[0025] The main frame 1 includes a main frame 11 and a main frame 2 12; one end of the main frame 11 and the main frame 2 12 is a connecting end, and the two are rotatably connected by bolts, and the other end is a free end, so as to realize the fan-shaped opening and closing of the main frame 1;

[0026] It also includes two symmetrically arranged connecting plates 5; the space between the two connecting plates 5 is used to accommodate the connecting ends of the main frame 2 12 and the main frame 1 11; the main frame 2 12 is fixed as a whole with the two connecting plates 5, and bolt holes are provided at positions corresponding to the two connecting plates 5 on the main frame 1 11, and angle fixing bolts 4 are passed through the bolt holes. The main frame 1 11 and the main frame 2 12 welded on the connecting plates 5 both rotate with the angle fixing bolts 4 as the center of the circle.

[0027] Preferably, the length of the main frame 11 is equal to the length of the main frame 2 12, which is 500 mm.

[0028] Preferably, the nut portion of the angle fixing bolt 4 is welded to the connecting plate 5 on the side close to the measuring member 3. The construction personnel can simultaneously clamp or loosen the main frame 11 and the main frame 2 12 by rotating the screw portion of the angle fixing bolt 4, so that the main frame 11 and the main frame 2 12 are relatively fixed or relatively rotated.

[0029] Further preferably, a bolt handle is provided on the top of the angle fixing bolt 4, and the provision of the bolt handle facilitates the construction workers to operate in a time-saving and labor-saving manner.

[0030] Further preferably, the length of the angle fixing bolt 4 is 80 mm, ensuring that the angle fixing bolt 4 has sufficient length to pass through the connecting plate 5 and the main frame 11 and fix them.

[0031] The two identical clamping members 2 are arranged at the free ends of the main frame 11 and the main frame 2 12, respectively used to fix the steel pipe to be welded; the clamping member 2 comprises a fixed base 22 and a vise base 23 fixed on the main frame 1; the fixed base 22 is threadedly connected with a vise bolt 21, and the end of the vise bolt 21 is directly opposite to the vise base 23; when in use, the steel pipe to be welded can be clamped between the vise bolt 21 and the vise base 23 by adjusting the feed of the vise bolt 21, and the steel pipe to be welded is perpendicular to the frame of the main frame;

[0032] Preferably, the clamping member 2 is arranged on the same side of the main frame 1 11 and the main frame 2 12, and the steel pipes to be welded are in the same plane, which is convenient for construction workers to perform welding operations.

[0033] The fixed base 22 includes a square base and a nut; a nut matching the size of the screw 212 is provided on the base welded to the main frame 1 11 and the main frame 2 12, and the screw 212 and the nut are used in conjunction with each other;

[0034] Preferably, the number of the nuts is 2, so as to improve the stability of the combination between the nuts and the screw rod 212.

[0035] Further preferably, the nut is an M10 nut.

[0036] The vise base 23 is square, arranged opposite to the fixed base 22, and welded to the main frame 1 11 and the main frame 2 12, thereby improving the stability of the vise base 23.

[0037] Preferably, the size of the fixed base 22 is 20mm×30mm×30mm, and the size of the vise base 23 is 60mm×30mm×30mm. The larger vise base 23 can ensure that there is enough space to fix the steel pipe to be welded;

[0038] The vise bolt 21 includes a screw rod 212 that is bolted to a fixed base 22 . A handle 211 is provided at one end of the screw rod 212 , and a gasket 213 for clamping the steel pipe to be welded is provided at the other end.

[0039] The handle 211 is convenient for construction workers to perform rotation operations.

[0040] The gasket 213 is made of a truncated cone-shaped metal material. The truncated cone shape ensures that the gasket 213 and the vise base 23 can clamp the steel pipe to be welded more stably; the metal material ensures sufficient strength to prevent the gasket 213 from being damaged during the clamping of the steel pipe to be welded, thereby affecting the construction progress.

[0041] Further preferably, the maximum diameter of the gasket 213 is greater than the diameter of the screw 212, thereby increasing the contact area between the gasket 213 and the steel pipe to be welded and improving the stability of clamping.

[0042] Preferably, the length of the screw rod 212 is 140 mm, ensuring that the distance between the gasket 213 and the vise base 23 is suitable for steel pipes to be welded of different sizes.

[0043] The measuring member 3 is arranged at a position close to the connection end of the main frame, and specifically includes an arc-shaped scale plate 31; one end of the scale plate 31 is welded to the main frame 11 or the main frame 2 12 to ensure the stability of the scale plate 31 and the accuracy of the zero scale line; the other end of the scale plate 31 is a free end, which does not affect the change of the angle between the main frame 11 and the main frame 2 12. The angle between the main frame 1 11 and the main frame 2 12 can be known by reading the value on the scale plate 31. 180° minus the angle between the main frame 1 11 and the main frame 2 12 is the angle between the steel pipes to be welded. Therefore, the construction personnel can quickly adjust the angle between the main frame 1 11 and the main frame 2 12 according to the required angle between the steel pipes to be welded, thereby improving the construction efficiency.

[0044] The utility model is not only applicable to the steel pipe to be welded, but also applicable to other forms of materials such as steel plates, channel steels, etc.

[0045] Working principle:

[0046] When in use, the screw rod 212 is rotated by controlling the handle 211 to fix the steel pipe to be welded between the vise base 23 and the gasket 213 on the main frame 11; according to the required welding angle, the main frame 212 is rotated, and the angle between the main frame 11 and the main frame 212 can be known by reading the value on the dial 31; since the steel pipe to be welded is perpendicular to the frame of the main frame, the steel pipe angle is equal to 180° minus the angle between the main frame 212 and the main frame 11. After determining the required angle, tighten the angle fixing bolt 4 so that the main frame 11 and the main frame 212 no longer rotate relative to each other; reserve the required length of the steel pipe to be tilted and fix it between the vise base 23 and the gasket 213 of the main frame 212; finally, weld the two steel pipes to be welded, and the angle between the two steel pipes meets the construction requirements. After completing the welding work, the device is disassembled from the two steel pipes for subsequent use.

[0047] The utility model reduces the number of workers required for guardrail welding work, and because it has a fixing function and an angle indication function, it reduces the time required for welding preparation, reduces labor intensity, improves the efficiency of welding work, and at the same time protects the safety of on-site construction personnel and reduces the probability of safety accidents.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
