DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] like Figure 1 and Figure 2 As shown, a structural diagram of a prefabricated building steel structure welding platform provided by an embodiment of the present invention includes a first bottom plate 1 and a second bottom plate 2 that are arranged to rotate with each other, and also includes:

[0034] The first clamping assembly 3, such as Figure 5 As shown, the first clamping assembly 3 is arranged on the first bottom plate 1, and the first clamping assembly 3 includes two support columns 301 arranged on the first bottom plate 1 at intervals, and the two support columns 301 are provided with first clamping members 5 and second clamping members 6 at corresponding positions, and a first lifting member 302 is fixedly arranged on the first bottom plate 1, and a vertically arranged mounting rod 303 is fixedly connected to the top of the first lifting member 302, and the first clamping member 5 and the second clamping member 6 are fixedly arranged on the mounting rod 303 at intervals, and the first lifting member 302 is used to drive the mounting rod 303 and the first clamping member 5 and the second clamping member 6 on the mounting rod 303 to move in the vertical direction;

[0035] The second clamping assembly 4, such as Figure 4 As shown, the second clamping assembly 4 is arranged on the second bottom plate 2, and the second clamping assembly 4 includes two support rods 401 arranged at intervals on the second bottom plate 2, and the first clamping member 5 is also fixedly arranged on the two support rods 401, and a second lifting member 402 is arranged on the top of the support rod 401, and a second clamping member 6 identical to that on the support column 301 is arranged on the top of the second lifting member 402, and the first clamping member 5 corresponds to the position of the second clamping member 6, and the second lifting member 402 is used to drive the second clamping member 6 to move in the vertical direction;

[0036] When the first lifting member 302 and the second lifting member 402 are in the initial state, all the first clamping members 5 are at the same height, all the second clamping members 6 are at the same height, the height of the first clamping member 5 is less than the height of the second clamping member 6, and the height difference between the first clamping member 5 and the second clamping member 6 is greater than or equal to twice the height difference between the first clamping member 5 and the second clamping member 6 when clamping the workpiece.

[0037] In one embodiment of the present invention, during use, the platform can fix two steel pipes to be welded by cooperating with each other through different first clamping members 5 and second clamping members 6, which not only acts on the welding process but also assists in cutting.

[0038] Since the first clamping member 5 on the second bottom plate 2 is in a fixed state, the second lifting member 402 is used to drive the second clamping member 6 to move downward, so that one of the steel pipes can be tightened at a fixed height, and the first lifting member 302 can drive the other steel pipe on the first clamping member 5 to move upward, and the steel pipe is tightened by cooperating with the two second clamping members 6 on the support column 301. At this time, since the two steel pipes are at different heights and are in a cross shape, there is no need to measure again when cutting, and the two steel pipe ends can be cut into bevels at one time (only the cutting tool needs to be moved in the vertical direction), and the two bevels also cooperate with each other. After the cutting is completed, the second lifting member 402 drives the steel pipe to move downward. At this time, the second clamping member 6 above it cooperates with the two first clamping members 5 on the support column 301, and the steel pipe can be tightened again at the bottom. At this time, the two steel pipes after cutting are at the same height, and the two cut bevels are directly fitted, so they can be directly welded, which can greatly simplify the process of steel pipe cutting and welding.

[0039] Since the first bottom plate 1 and the second bottom plate 2 are rotatably arranged, the angle between the two fastened steel pipes can be adjusted, so the platform can adapt to various forms of steel pipe welding processing in steel structure welding.

[0040] In one embodiment of the present invention, since the first clamping member 5 and the second clamping member 6 of the platform are used to fix a workpiece such as a steel pipe, and the first clamping member 5 and the second clamping member 6 have the same structure, the two can be used as follows: Figure 5 In the form shown, a clamping block 502 is detachably fixed on a mounting frame 501, and the mounting frame 501 is used to connect with other structures. At the same time, the clamping block 502 can be replaced according to the shape of the fastened workpiece, which effectively increases the use range of the platform; the first lifting member 302 and the second lifting member 402 can be in the form of an electric telescopic rod, and of course, they can also be in the form of a hydraulic telescopic rod, as long as they can drive the corresponding structure to lift and lower to complete the fixing of the steel pipe; Figure 2As shown, although the first clamping member 5 is provided on both the support column 301 and the support rod 401, their heights are the same, so the fastening position of the steel pipe on the second bottom plate 2 is fixed, and when the first lifting member 302 drives the second clamping member 6 above it to move downward, the steel pipe on the first bottom plate 1 will also be fixed at the same height, and at this time, the two steel pipes have been cut, so the two are directly spliced ​​together; before cutting the steel pipe, the platform needs to first place a steel pipe on the first bottom plate 1 for fixing, and use the first lifting member 302 to drive the first clamping member 5 above it to move upward, and the first clamping member 5 and the two second clamping members 6 on the top of the support column 301 cooperate with each other to achieve the steel pipe fastening process, and at this time the steel pipe has been raised in height, so that when another steel pipe is fastened on the second bottom plate 2, there will be no interference between the two steel pipes, and at the same time, the crossed state is maintained, which is convenient for the subsequent one-time cutting of two steel pipes; as shown Figure 8 As shown, the distance between the two support rods 401 is greater than the distance between the two support columns 301, and the first clamping assembly 3 and the second clamping assembly 4 are respectively located on the first bottom plate 1 and the second bottom plate 2, and the first bottom plate 1 and the second bottom plate 2 can be opened or closed. When in use, the two need to be opened and adjusted to a suitable angle so that the inclined surfaces of the cut steel pipe ends can also be angled. When not in use, in order to facilitate the movement of the platform, the first bottom plate 1 and the second bottom plate 2 can be closed. Because the distance between the two support rods 401 is greater than the distance between the two support columns 301, the platform can avoid interference between the first clamping assembly 3 and the second clamping assembly 4 after closing.

[0041] like Figure 2 and Figure 4 As shown, as a preferred embodiment of the present invention, the second clamping member 6 at the top of the support column 301 is slidably connected to the support column 301, the cross-section of the support column 301 is a polygonal structure, and the top of the support column 301 is fixedly connected with a limit cover 304 for limiting the moving stroke of the second clamping member 6, and an adjustment component 7 is arranged between the two support columns 301, and the adjustment component 7 is used to adjust the distance between the first clamping member 5 and the second clamping member 6 on the two support columns 301.

[0042] In one case of the present embodiment, the adjusting component 7 is located on one side of the first clamping member 5 and the second clamping member 6 on the first lifting member 302 and the mounting rod 303. The adjusting component 7 includes a first cross frame 701 and a second cross frame 702 which are arranged horizontally at intervals. The two ends of the first cross frame 701 are respectively fixedly connected to the two support columns 301, and the connection between the first cross frame 701 and the support column 301 is located at the bottom of the first clamping member 5 on the support column 301. The two ends of the second cross frame 702 are respectively fixedly connected to the second clamping members 6 at the top of the two support columns 301. An adjusting member 703 is arranged between the first cross frame 701 and the second cross frame 702. The adjusting member 703 is used to drive the second cross frame 702 to move in the vertical direction. The adjusting member 703 can be in the form of a manual screw, or of course, in the form of an electric telescopic adjustment. It is feasible as long as the distance between the first cross frame 701 and the second cross frame 702 can be changed. In the actual steel structure welding process, various steel pipes will inevitably be used, which leads to the fact that the outer dimensions of the steel pipes are not fixed. The characteristic of this platform is that the steel pipes are staggered up and down during cutting and are butt-jointed during welding. If the distance between the first clamping member 5 and the second clamping member 6 on the support column 301 is not enough, that is, the distance between the two is less than twice the size of the steel pipe, then the two steel pipes cannot reach the state of staggered up and down, and there will be interference between the two steel pipes. Therefore, the height of the second clamping member 6 at the top of the support column 301 can be controlled by the adjusting member 703, so as to ensure that when welding steel pipes of different sizes, the two fixed steel pipes can be staggered up and down, and the distance between the first clamping member 5 and the second clamping member 6 at the top of the first lifting member 302 is generally set to a larger distance. As long as it is ensured that the steel pipe can be put in, the distance between the two will not affect the tightening of the steel pipe at the top or bottom. Figure 4 As shown, a distance scale 305 indicating the lifting and lowering of the second clamping member 6 is provided on the top of the support column 301, so as to facilitate the user to adjust it.

[0043] like Figure 4 As shown, the above embodiment is used as a basis for supplementary explanation, the first clamping members 5 on the two support columns 301 are slidably connected to the support columns 301, and the first cross frame 701 is used to limit the movement of the first clamping members 5 toward the bottom of the support column 301, and the first clamping members 5 on the mounting rod 303 are fixedly connected on both sides with a laterally arranged lifting frame 8, and the other end of the lifting frame 8 is located at the bottom of the first clamping members 5 on both sides. When the first lifting member 302 drives the first clamping members 5 on the mounting rod 303 to rise, the lifting frame 8 is used to drive the first clamping members 5 on both sides to rise synchronously.

[0044] In one case of this embodiment, this platform is for welding two steel pipes at a set angle, that is, the two steel pipes are welded through the end bevel. Since the second clamping assembly 4 is used to hold the steel pipe through two first clamping members 5 arranged at intervals, the steel pipe can maintain a horizontal and stable state. However, during the process of fixing the upper and lower parts of the first clamping assembly 3, the steel pipe needs to be driven upward by the first clamping member 5 in the middle position, and then the first clamping member 5 needs to support the steel pipe to move downward. There is only one contact point between the steel pipe and this platform, which makes it easy for the steel pipe to move downward. Unbalanced tilting and side sliding may occur easily. After the first clamping members 5 on the support column 301 are connected in a sliding manner, the first cross frame 701 will first limit the two first clamping members 5 on the support column 301, which will not affect the tightening of the steel pipe at the bottom. At the same time, due to the existence of the two lifting frames 8, no matter whether the steel pipe is rising or falling, there are always three first clamping members 5 as support points under the steel pipe, so that the placed steel pipe can always maintain a horizontal and stable state, effectively solving the problems that arise in the platform under the above-mentioned special circumstances.

[0045] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, an angle control component 9 is arranged between the first base plate 1 and the second base plate 2, and the angle control component 9 is used to adjust the angle between the first base plate 1 and the second base plate 2 which are rotatably arranged.

[0046] In one case of the present embodiment, the angle control assembly 9 includes connecting columns 901 respectively on the first base plate 1 and the second base plate 2, and also includes a telescopic rod 902, the two ends of the telescopic rod 902 are rotatably connected to the two connecting columns 901 respectively, and the telescopic rod 902 is located at the bottom of the first base plate 1 and the second base plate 2. The telescopic rod 902 can be in the form of electric telescopic, and of course, it can also be in the form of hydraulic telescopic. The telescopic rod 902 can control the first base plate 1 and the second base plate 2 to open or close, and the angle between the two can also be adjusted. Similarly, the welding angle of the steel pipe will also change, and there is no need to measure the ends of the two steel pipes.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the above embodiment is expanded and described, the first base plate 1 and the second base plate 2 are both provided with a through slide groove 10 arranged along their own length direction, the connecting column 901 is located in the through slide groove 10 and can move along the through slide groove 10, and both ends of the through slide groove 10 are provided with limiting grooves 11, and the top of the connecting column 901 is fixedly connected with a limiting plate 12 that matches the limiting groove 11, and the top of the limiting plate 12 is fixedly connected with an operating handle 13 for driving the connecting column 901 to move along its axial direction. When the limiting plate 12 is located in the limiting groove 11, the movement of the connecting column 901 in the through slide groove 10 is restricted.

[0048] In one case of this embodiment, generally speaking, due to the limitation of the overall structure size, the telescopic stroke of the telescopic rod 902 is certain, which leads to a certain range of the angle between the first bottom plate 1 and the second bottom plate 2. In conventional cases, if the platform can weld two steel pipes greater than 90°, then the length of the telescopic rod 902 itself has a lower limit, which means that if Figure 8 The matching state of the first bottom plate 1 and the second bottom plate 2 shown may not be realized, but after the through-slide groove 10 and the limit groove 11 are opened, the adjustment angle range of the telescopic rod 902 with a fixed telescopic stroke can be flexibly changed. The length of the connecting column 901 needs to be greater than the thickness of the first bottom plate 1 or the second bottom plate 2, so that the limit plate 12 can be controlled to enter the limit groove 11 or move out of the limit groove 11 by using the operating handle 13. For the sake of convenience, the limit groove 11 is defined as the distal end or the proximal end according to the distance from the rotation connection between the first bottom plate 1 and the second bottom plate 2. The two limit plates 12 are positioned at When the telescopic rod 902 is in the two distal limit grooves 11, the angle can be adjusted within a certain range. If a larger angle of steel pipe welding is required at this time, the limit plate 12 can be moved to the two proximal limit grooves 11 at this time, so that the maximum angle between the first base plate 1 and the second base plate 2 can be increased. In addition, if one limit plate 12 is placed in the distal limit groove 11 and the other limit plate 12 is placed in the proximal limit groove 11, the angle range between the first base plate 1 and the second base plate 2 will inevitably change. Through the above-mentioned simple matching structure, the angle adjustment of the platform when welding steel pipes can be made more flexible and variable.

[0049] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, as a preferred embodiment of the present invention, a shaft body 14 is provided at the connection between the first base plate 1 and the second base plate 2, and a first connecting ring 15 and a second connecting ring 16 are provided on the shaft body 14. The first connecting ring 15 is fixedly connected to the shaft body 14 and the first base plate 1, and the second connecting ring 16 is rotatably connected to the shaft body 14 and fixedly connected to the second base plate 2. An angle disk 17 is fixedly provided on the top of the second connecting ring 16, and an indicator 18 matching the angle disk 17 is fixedly connected to the top of the shaft body 14.

[0050] In one case of this embodiment, when the angle control assembly 9 is used to adjust the welding angle of the two steel pipes, the cooperation of the angle disk 17 and the indicator 18 enables the operator to observe the corresponding angle more intuitively, thereby facilitating confirmation of the operator's welding requirements.
