[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasound. Steel structure space frame is a spatial rod structure composed of many rods connected by nodes according to certain rules. When welding steel structure space frame, an operating platform for welding steel structure space frame is used.

[0003] In the existing technology, the operating platform for welding steel structure space frames has a relatively simple structure, mainly consisting of a platform body and supporting columns. During welding, the steel structure space frame is placed inside the platform body for welding to prevent the flying of welding debris. However, in the use of existing operating platforms for welding steel structure space frames, the platform body is usually welded and fixed to the top of the supporting columns, making it difficult to replace the platform body with the corresponding specifications according to the specifications of the steel structure space frame, thus reducing the practicality of the operating platform. Utility Model Content

[0004] The purpose of this utility model is to provide an operating platform for welding steel structure space frames to solve the problems mentioned in the background art.

[0006] A pull rod is slidably installed at one end of the positioning ring plate. Two limit springs are symmetrically installed on both sides of the pull rod. A pull plate is connected to one end of the pull rod, and a trapezoidal block is installed at the other end of the pull rod. A positioning groove is opened on the side wall of the mounting column near the trapezoidal block, and a limit rod is rotatably connected to the bottom end of the pull plate. A fixing groove is opened on the side wall of the positioning ring plate near the limit rod.

[0007] Preferably, the mounting column is fixedly installed on the top of the column, an anti-slip pad is fitted on the outer wall of the bottom end of the mounting column, and a base plate is fixedly installed on the bottom end of the column.

[0008] Preferably, the threaded sleeve is fixedly installed on the platform body, and four reinforcing ribs are evenly arranged. One end of each of the four reinforcing ribs is fixedly connected to the outer wall of the threaded sleeve, and the top ends of each of the four reinforcing ribs are fixedly installed at the bottom of the platform body.

[0009] Preferably, the positioning ring plate is fixedly installed at the bottom end of the threaded sleeve, the inner wall of the positioning ring plate is connected to the inside of the threaded sleeve, the top end of the mounting post passes through the positioning ring plate and is inserted into the threaded sleeve, and the side wall of the mounting post near the threaded sleeve is provided with a connecting thread, which is threadedly connected to the inner wall of the threaded sleeve.

[0010] Preferably, the positioning ring plate has a shrinkage groove on the inner wall near the trapezoidal block, one end of the trapezoidal block is slidably connected to the inner wall of the shrinkage groove, one end of the pull rod is fixedly connected to the pull plate, and the other end of the pull rod is slidably inserted into the shrinkage groove and fixedly connected to the trapezoidal block.

[0012] Preferably, the limiting rod is T-shaped, and both ends of the top of the limiting rod are rotatably connected to the pull plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model utilizes a fixing groove at one end of the positioning ring plate. When the pull plate is pulled to allow the trapezoidal block to enter the contraction groove, the limiting rod is rotated to insert it into the fixing groove, facilitating the limiting of the trapezoidal block. The threaded connection between the mounting column and the inner wall of the threaded sleeve allows for a detachable connection between the mounting column and the threaded sleeve. Through the limiting springs on both sides of the pull rod, when the pull plate is pulled to allow the limiting rod to leave the fixing groove, the trapezoidal block can be inserted into the positioning groove under the elastic action of the limiting springs. This prevents relative rotation between the positioning ring plate and the mounting column, improving the stability of the platform body installation. Furthermore, it enables the replacement of the platform body with the corresponding specifications according to the specifications of the steel structure space frame, thus improving the practicality of the operating platform.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 6This utility model provides a technical solution: an operating platform for welding steel structure space frame, comprising: a column 4, a platform body 1 connected to the top of the column 4, a threaded sleeve 3 installed at the bottom center of the platform body 1, reinforcing ribs 2 provided on the side wall of the threaded sleeve 3, a positioning ring plate 8 installed at the bottom of the threaded sleeve 3, an installation column 6 connected to the top of the column 4 near the positioning ring plate 8, the top of the installation column 6 inserted into the threaded sleeve 3 and threadedly connected to the inner wall of the threaded sleeve 3, depending on the specifications of the steel structure space frame, the platform body 1 can be set in several sets according to the corresponding specifications for backup, and the bottom of the platform body 1 of different specifications is provided with the same specification of threaded sleeve 3, so as to replace and install the platform body 1 of the corresponding specifications; the installation column 6 is fixedly installed on the top of the column 4, and an anti-slip pad 9 is sleeved on the outer wall of the bottom of the installation column 6, and a base plate 5 is fixedly installed at the bottom of the column 4, so that the top of the column 4 is tightly connected to the bottom of the positioning ring plate 8 through the anti-slip pad 9, thereby improving the installation stability of the positioning ring plate 8. The threaded sleeve 3 is fixedly installed on the platform body 1. Four reinforcing ribs 2 are evenly arranged, one end of each of the four reinforcing ribs 2 is fixedly connected to the outer wall of the threaded sleeve 3, and the top ends of each of the four reinforcing ribs 2 are fixedly installed at the bottom end of the platform body 1, which can improve the strength of the platform body 1. The positioning ring plate 8 is fixedly installed at the bottom end of the threaded sleeve 3. The inner wall of the positioning ring plate 8 is connected to the inside of the threaded sleeve 3. The top end of the mounting post 6 passes through the positioning ring plate 8 and is inserted into the threaded sleeve 3. The side wall of the mounting post 6 near the threaded sleeve 3 has a connecting thread 7, which is threadedly connected to the inner wall of the threaded sleeve 3, which facilitates the detachable connection of the mounting post 6 and the threaded sleeve 3.

[0024] A pull rod 13 is slidably mounted on one end of the positioning ring plate 8. Two limit springs 15 are symmetrically mounted on both sides of the pull rod 13. A pull plate 12 is connected to one end of the pull rod 13, and a trapezoidal locking block 11 is mounted on the other end of the pull rod 13. A positioning groove 10 is provided on the side wall of the mounting column 6 near the trapezoidal locking block 11, and a limit rod 17 is rotatably connected to the bottom end of the pull plate 12. A fixing groove 16 is provided on the side wall of the positioning ring plate 8 near the limit rod 17. A shrinkage groove 14 is provided on the inner wall of the positioning ring plate 8 near the trapezoidal locking block 11. One end of the trapezoidal locking block 11 is slidably connected to the inner wall of the shrinkage groove 14. One end of the pull rod 13 is fixedly connected to the pull plate 12, and the other end of the pull rod 13 is slidably inserted into the shrinkage groove 14 and fixedly connected to the trapezoidal locking block 11. When the pull plate 12 is pulled from the outside of the positioning ring plate 8, the trapezoidal locking block 11 can be moved along the shrinkage groove 14, thereby facilitating the limiting of the mounting column 6 and enabling the disassembly and assembly of the platform body 1. Both limiting springs 15 are located inside the contraction groove 14. One end of each limiting spring 15 is fixedly mounted on the trapezoidal block 11, and the other end of each limiting spring 15 is fixedly connected to the inner wall of the contraction groove 14 near the pull plate 12. When the trapezoidal block 11 slides into the positioning groove 10, the limiting spring 15 is in its natural length state. The limiting rod 17 is T-shaped, and both ends of the top of the limiting rod 17 are rotatably connected to the pull plate 12.

[0025] When this device is in operation, the fixed groove 16 at one end of the positioning ring plate 8 allows the trapezoidal block 11 to enter the contraction groove 14 when the pull plate 12 is pulled. The limiting rod 17 is then rotated to insert into the fixed groove 16, which helps to limit the trapezoidal block 11. At this time, it is easy to pass the top of the mounting column 6 through the positioning ring plate 8 and rotate it into the threaded sleeve 3. The threaded connection between the mounting column 6 and the inner wall of the threaded sleeve 3 facilitates a detachable connection between the mounting column 6 and the threaded sleeve 3. Through the limiting springs 15 on both sides of the pull rod 13, when the pull plate 12 is pulled and the limiting rod 17 leaves the fixed groove 16, the end of the limiting rod 17 away from the pull plate 12 is vertically downward under the action of gravity. The trapezoidal block 11 can be inserted into the positioning groove 10 under the elastic action of the limiting spring 15, making it difficult for the positioning ring plate 8 and the mounting column 6 to rotate relative to each other. This improves the stability of the platform body 1 installation and enables the function of replacing the platform body 1 with the corresponding specification according to the specifications of the steel structure grid, thus improving the practicality of the operating platform.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
