[0002] As a type of initial support steel for tunnel engineering grade IV and V surrounding rock, grid steel frame is widely used in municipal, highway, railway and water conservancy and hydropower projects. The structure of grid steel frame is mainly composed of main reinforcement, 8-shaped knot, mouth reinforcement and joint steel plate, among which the welding of main reinforcement and 8-shaped knot is an important process in grid steel frame processing.

[0003] The patent with the publication number CN213163748U discloses a tunnel grid steel frame processing device, including a limit plate, the limit plate is used to adapt to the end face of the connection end of the grid steel frame segment, and the limit plate is used to abut the surface of the connection end end face and is connected to two positioning groups, the two positioning groups are used to position the two angle steels on the connection end, each positioning group includes at least one positioning member, and all the positioning members of each positioning group are adapted to the corresponding bolt holes on the corresponding angle steels. It is convenient and fast to use, simple to operate, and can quickly ensure that the second connection plates of the two angle steels are on the same plane; and it can quickly locate the relative position of the two angle steels through the positioning members of the positioning group and the bolt holes, and can accurately control the spacing between the bolt holes of the two angle steels at the same connection end, which can improve the welding quality of the angle steel welded to the grid steel frame segment, and is beneficial to the installation quality control of the grid steel frame.

[0004] In the actual use of grating steel frame processing devices such as the above-mentioned ones, it is necessary to manually maintain the main reinforcement against the hole on the limit plate to ensure the angular relationship between the angle iron and the main reinforcement and prevent the main reinforcement from being misplaced, which makes the welding quality between the two substandard. At the same time, the positional relationship between the main reinforcements is also maintained by manpower. The slightest carelessness will cause the welded grating steel frame to deform, and the processing personnel mostly work in a squatting position during the processing, which is quite strenuous for the processing personnel. This is not only time-consuming and labor-intensive, resulting in low processing efficiency, but also the welding quality of the grating steel frame cannot be guaranteed, which is very unfavorable for the welding work of the grating steel frame.

[0030] like Figure 1-4 As shown, the utility model provides a grid steel frame processing welding quality control device, including an arc-shaped bearing platform 1. The arc-shaped design of the arc-shaped bearing platform 1 can not only meet the specific structure of the grid steel frame, but also facilitate the welders to get closer to the grid steel frame for welding, so as to improve the welding efficiency. At least three support columns 4 for supporting the main reinforcement 6 are evenly distributed in the middle of the arc-shaped bearing platform 1, and control panels 3 are respectively provided at both ends of the arc-shaped bearing platform 1 to fix the main reinforcement 6 of the grid steel frame to avoid the welders holding or correcting it. The support column 4 and the control panel 3 are respectively connected to the arc-shaped bearing platform 1 through a C-type kit 2. The position of the support column 4 and the control panel 3 can be changed by moving the position of the C-type kit 2, so as to meet the perfect fixation of the main reinforcement 6 and prevent it from being dislocated or deformed.

[0031] Two support rods 41 extending forward are provided on the front side of the support column 4 from top to bottom, and two limit members 5 are provided in the extension direction of the support rod 41. The main reinforcement 6 is stuck in the limit members 5. Through the arrangement of the support rods 41 and the limit members 5, the four main reinforcements 6 can be fixed equidistantly and regularly, so as to facilitate the welding of other components thereon, and also prevent the main reinforcement 6 from being misplaced or deformed during the welding process, thereby playing a role in controlling the welding quality. Two positioning rods 31 are equidistantly provided on the upper and lower sides of the inner end surface of the control plate 3, and angle irons 7 are respectively sleeved on the upper and lower positioning rods 31. The angle irons 7 are sleeved on the positioning rods 31 through the fixing holes 71, and the ends of the main reinforcements 6 are against the angle irons 7. Through the positioning rods 31, the angle irons 7 can be controlled to be welded to the ends of the main reinforcements 6 under the premise of ensuring the welding quality.

[0032] In the above scheme, a clamping edge 12 is provided at the top of the front side of the arc-shaped supporting platform 1, and an inwardly inclined slope 121 is provided between the front side and the bottom of the clamping edge 12. A clamping surface 21 is provided at the front side of the C-type kit 2, and the clamping surface 21 corresponds to the slope 121. A bolt 22 is threadedly connected to the clamping surface 21, and the head of the bolt 22 abuts against the slope 121.

[0033] As an optimized technical solution of the utility model, the clamping edge 12 can prevent the C-type kit 2 from falling off the arc-shaped supporting platform 1, and the design of the tightening surface 21 can make the head of the bolt 22 abut against the slope 121, and then by tightening the bolt 22, the rear side of the C-type kit 2 can be tightened against the rear side of the arc-shaped supporting platform 1, and then the C-type kit 2 can be fixed at a certain position of the arc-shaped supporting platform 1, so as to facilitate the adjustment and fixation of the position of the support column 4 and the control panel 3.

[0034] In the above solution, the limiter 5 is a U-shaped groove structure, the main rib 6 is stuck in the groove of the limiter 5, and a rotating column 51 is provided at the bottom of the limiter 5, and the rotating column 51 is rotatably connected to the top of the support rod 41.

[0035] As an optimized technical solution of the utility model, the groove design of the limiter 5 can ensure the effective insertion of the main reinforcement 6 and play a limiting role therefor. At the same time, the limiter 5 can also rotate on the horizontal plane with the movement of the main reinforcement 6 to ensure that the insertion process of the main reinforcement 6 is smoother and the processing efficiency is improved.

[0036] In the above solution, four limiting holes 32 corresponding to the ends of the main ribs 6 are provided on the inner end surface of the control plate 3 , and the ends of the main ribs 6 are inserted into the limiting holes 32 .

[0037] As an optimization technical solution of the utility model, the limiting hole 32 can limit and fix the end of the main reinforcement 6 to keep it in the fixed shape, prevent the main reinforcement 6 from being deformed during the processing and welding process, and ensure the welding gap with other components to improve the welding quality.

[0038] In the above solution, the two ends and the middle of the bottom surface of the arc-shaped supporting platform 1 are respectively connected with supporting leg members 11, and the supporting leg members 11 are in an eight-shaped structure.

[0039] As an optimized technical solution of the utility model, the setting of the support leg 11 can make the arc-shaped supporting platform 1 stand on the ground, and set the arc-shaped supporting platform 1 at a comfortable and reasonable welding height, so that welders can perform welding work in a comfortable welding environment. At the same time, the eight-shaped supporting leg 11 can ensure the stability of the support and prevent the arc-shaped supporting platform 1 from tipping over easily.

[0040] Specific implementation cases:

[0041] During the processing and welding of the grid steel frame, the arc-shaped supporting platform 1 is erected at the selected processing position through the supporting leg members 11. The positions of the supporting columns 4 and the control panel 3 can be adjusted according to the length and curvature of the main reinforcement 6, and the adjustment of the two is achieved by moving the C-type kit 2 on the arc-shaped supporting platform 1. By twisting the bolt 22, the C-type kit 2 and the arc-shaped supporting platform 1 lose their tight contact effect, and then the C-type kit 2 can be moved on the arc-shaped supporting platform 1, and the supporting columns 4 and the control panel 3 are moved to the appropriate position and fixed by the bolts 22.

[0042] Next, the four main bars 6 are respectively inserted into the grooves of the upper limit piece 5 on the support rod 41, and the ends are inserted into the limiting holes 32, and then the angle iron 7 is sleeved on the positioning rod 31 through the fixing holes 71, so that the angle iron 7 is abutted against the main bars 6, so as to facilitate welding the angle iron 7 to the ends of the main bars 6. At the same time, due to the equidistant arrangement of the support rod 41 and the limiting piece 5, and the arrangement of the upper limit holes 32 on the control board 3, the distance between two mutually parallel main bars 6 in the four main bars 6 can be controlled to be equal at any position, so that the welding quality between the main bars 6 and the angle iron 7 or other components can be effectively controlled, ensuring that the welding gap is the same and there is no situation where the weld is large and the welding quality is low. At the same time, the welding efficiency is also effectively improved, and the purpose of controlling the welding quality can be achieved while saving time and effort.

[0043] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
