Description

Technical Field

[0001] This utility model relates to the field of tooling fixing device technology, specifically to a structural component welding platform with protective function. Background Technology

[0002] Structural components are various building blocks that form the physical structure of an engineering project after being hoisted, assembled, and installed during construction. They have the function of bearing and transmitting loads. Coal mining machinery uses a large number of structural components, such as top beams, hydraulic supports, and intermediate troughs. These structural components are relatively large. For example, the top beam in coal mining machinery is quite large. It is generally used horizontally in conjunction with the hydraulic system, but during processing, it needs to be placed vertically for easy welding. Due to height limitations, welding may even require climbing to a certain height.

[0003] To ensure construction safety, a backrest is pre-installed on the traditional welding platform. One side of the semi-finished top beam is placed against the backrest and then secured with chains. This process presents the following problems:

[0004] 1. The backrest and welding platform are fixed and cannot be moved. Therefore, the fixed backrest can easily create welding dead angles for the workpiece after it is placed. Moreover, the backrest is generally a "U" shaped frame structure with a cavity in the middle. Therefore, it can only provide support for some large workpieces that need to be welded and is not suitable for small and medium-sized workpieces. If the workpiece is too small to meet the support requirements, it is easy to tip over during welding, causing safety accidents.

[0005] 2. After the workpiece is hoisted, the iron chain must be attached in time. After welding is completed, the iron chain must be opened in time. When the operator moves, the position of the iron chain cannot be clearly seen, which makes it particularly easy for safety accidents to occur. Utility Model Content

[0006] To overcome the above-mentioned defects, the purpose of this utility model is to provide a structural component welding platform with protective function, which ensures the accuracy of workpiece position and improves the safety of operators by setting a fixed shaft with an insertion and an adjusting screw on the fixed shaft.

[0007] To achieve the above objectives, this utility model provides a structural component welding platform with protective function, characterized in that it includes a welding platform and a fixed shaft, the welding platform is provided with a plurality of through holes, the through holes are perpendicular to the welding platform, and the bottom of the fixed shaft is inserted into the through holes;

[0008] The fixed shaft is provided with a plurality of adjustment holes, and at least one of the adjustment holes is provided with a positioning mechanism. The positioning mechanism includes a positioning screw, which is screwed into the adjustment hole. The end of the positioning screw penetrates the adjustment hole and abuts against the side of the workpiece.

[0009] Preferably, one end of the positioning screw is provided with a top block, and the other end away from the top block is also provided with a rotating handle.

[0010] Preferably, the welding platform is hollow and is formed by a top support plate, a bottom support plate, and side plates.

[0011] Preferably, a plurality of hollow tubes are fixed between the top support plate and the bottom support plate, and the through hole is the central hole of the hollow tube.

[0012] Preferably, a sleeve is installed in the central hole of the hollow tube.

[0013] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0014] 1. Because multiple through holes are set on the welding platform, the insertion position of the fixed shaft can be adjusted in time according to the size and position of the workpiece to be welded. This can provide better protection for the workpiece to be welded. After welding is completed, the fixed shaft can be removed. Compared with the previous chain fixation, the operation is simpler and more efficient, and the entire positioning process is more accurate.

[0015] 2. Because multiple adjustment holes are set and positioning screws are installed in the adjustment holes, the support of the workpiece to be welded can be further adjusted by using the positioning screws. This is especially suitable for situations where the widths at both ends of some structural parts are inconsistent, and the positioning will be more accurate. This makes the positioning and operation more user-friendly for welding workers and can also ensure the quality of the welded products.

[0016] 3. Since the fixed shaft and positioning screw are both rigid support components, there is no need to use flexible protective components such as chains. Therefore, the support effect of the welded parts is better, and there will be no significant tilting. The center of gravity is stable, and even if the operators climb to weld, good protection can still be achieved, ensuring construction safety. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0027] See Figures 1-4 This utility model provides a structural welding platform 1 with protective function, including a welding platform 1 and a fixed shaft 2. The welding platform 1 has multiple through holes perpendicular to it, and the bottom of the fixed shaft 2 is inserted into each through hole. The fixed shaft 2 has multiple adjustment holes 21, and at least one adjustment hole 21 contains a positioning mechanism 3. The positioning mechanism 3 includes a positioning screw 31, which is screwed into the adjustment hole 21. The end of the positioning screw 31 penetrates the adjustment hole 21 and abuts against the side of the workpiece 4. In use, the workpiece 4 is typically hoisted to the designated position on the welding platform 1. The fixed shaft 2 is placed in two hollow tubes 12 according to the approximate desired position. The workpiece 4 is lowered to the designated position, and then at least two fixed shafts 2 are inserted. Based on the height of workpiece 4, a positioning mechanism 3 is installed in one of the adjustment holes 21 of the fixed shaft 2. By rotating the handle 33, the extension length of the positioning screw 31 is adjusted to ensure that the top block 32 is in contact with workpiece 4, ensuring accurate positioning and that workpiece 4 will not tilt. Finally, the hoisting auxiliary equipment is removed, and the welding operation is performed. After welding is completed, workpiece 4 is first connected to the hoisting equipment, and then one side of the fixed shaft 2 is removed to complete the hoisting and transfer.

[0028] The positioning screw 31 of this invention has a top block 32 at one end and a rotating handle 33 at the other end away from the top block 32. The positioning screw 31 and top block 32 further prevent the workpiece 4 from tilting. Since the structural components are generally quite heavy, even if an operator stands on them for welding, as long as the center of gravity doesn't change too much, there will be no impact. Generally, 4-6 positioning shafts are needed, and the height and position of the positioning screw 31 are adjusted appropriately according to the length and position of the workpiece 4.

[0029] The welding platform 1 of this invention is hollow and is formed by a top support plate 11, a bottom support plate 14, and side plates 13. Multiple hollow tubes 12 are fixed between the top support plate 11 and the bottom support plate 14, with the through holes being the central holes of the hollow tubes 12. (See also...) Figure 4 In this system, the top support plate 11 and the bottom support plate 14 are of the same model and size, and the side plate 13 is used to connect the top support plate 11 and the bottom support plate 14. A hollow tube 12 is welded or bonded between the two. The hollow tube 12 not only serves as a reinforcing rib to enhance the rigidity of the welding platform 1, but can also be used to directly insert and fix the shaft 2. Due to its hollow structure, the weight of the entire welding platform 1 can be significantly reduced, making it suitable for hoisting and moving.

[0030] In this invention, sleeves are installed in the central holes of the hollow tube 12. The sleeves are used to improve the wear resistance of the hollow tube 12 and facilitate its replacement later. At the same time, since the diameter of the hollow tube 12 is relatively large, adding sleeves can keep the fixed shaft 2 as vertical as possible.

[0031] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
