Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and particularly relates to a welding platform for municipal engineering construction. Background Art

[0002] Municipal engineering refers to various projects related to municipal public facilities such as urban transportation, environmental sanitation, landscaping, urban water supply and drainage, heating, gas, and electricity. It mainly includes various municipal public works such as urban roads and bridges, water supply and drainage (including sewage and rainwater), electricity, communication, and lighting. During the use of the existing welding platforms for municipal engineering construction, they cannot be docked and welded according to the welding surface of the pipeline. Once welding is carried out on the ground or after the platform is spliced, it often requires multiple flips, resulting in relatively poor welding effects and further low welding efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a welding platform for municipal engineering construction to overcome the above-mentioned defects in the prior art.

[0004] According to a welding platform for municipal engineering construction of the utility model, it includes a main box body. An upward-opening welding cavity is provided inside the main box body. Two groups of rotation cavities that are upward-opening and symmetric left and right are provided inside the main box body. A rotating shaft is rotatably provided between the front and rear walls of the rotation cavity. A rotating machine frame is fixedly provided on the outer circular surface of the rotating shaft. Furthermore, the rotating machine frame plays a role in adjusting according to the angle of the welding surface of the pipeline. A push machine frame that can move back and forth is provided above the rotating machine frame. A positioning cavity that is upward-opening is provided inside the push machine frame. An arc-shaped groove is provided on the lower wall of the positioning cavity, thereby ensuring the stability of the pipeline. Multiple groups of clamping machine frames that can move towards each other and are evenly distributed in the front, rear, left, and right directions are provided inside the positioning cavity. Furthermore, the clamping machine frames play a clamping role.

[0005] In some embodiments, multiple groups of threaded sliders that are evenly distributed left and right are rotatably provided on the front and rear end faces of the push machine frame. A threaded shaft that can move back and forth is provided on the outer circular surface of the threaded slider. The threaded shaft is in threaded cooperation with the threaded slider. The upper end face of the threaded shaft is fixedly connected to the clamping machine frame. A docking pipeline is provided above the push machine frame.

[0006] In some embodiments, a push cavity connected to the outside is provided inside the rotating machine frame. A push shaft is rotatably provided between the left and right walls of the push cavity. A push slider that can move left and right is provided on the outer circular surface of the push shaft. The upper end face of the push slider is fixedly connected to the push machine frame. A push motor is fixedly provided inside the rotating machine frame. One side end face of the push shaft away from the center of symmetry is power-connected to the push motor.

[0007] In some embodiments, a rotating motor is fixedly arranged inside the rear wall of the rotating cavity, and the rear end face of the rotating shaft is power-connected to the rotating motor.

[0008] In some embodiments, a counterweight block is fixedly arranged on the lower end face of the main box body, and thus the counterweight block plays a role in counterweight. A controller is fixedly arranged on the upper end face of the front side of the main box body, and thus the controller plays a role in coordinating various movements.

[0009] Compared with the prior art, the advantages of the present utility model are as follows:

[0010] 1. In the present utility model, the threaded slider is in threaded cooperation with the threaded shaft, so as to drive the symmetrically arranged front and rear clamping frames to move towards each other, thereby realizing the clamping and fixing of the butt joint pipe. And due to the provision of multiple groups of clamping frames, the clamping and fixing of multiple points on the outer circumferential surface of the butt joint pipe are realized, thereby ensuring the stability of clamping and subsequent welding. The inner groove is arc-shaped, thereby ensuring the stability of placing the pipe on the upper side of the pushing frame.

[0011] 2. In the present utility model, according to the angle of the welding surface of the butt joint pipe, the symmetrically arranged left and right rotating motors are started at this time, and the rotating shaft is driven to rotate at this time, so as to drive the rotating frame, the pushing frame and the clamped pipe to rotate until the two symmetrically arranged left and right butt joint pipes and the welding surface reach the horizontal position. At this time, the pushing motors are respectively controlled to start, and the pushing shaft is driven to rotate at this time, so as to drive the pushing slider, the pushing frame and the clamped pipe to move towards each other, thereby ensuring that the adjustment and butt joint can be carried out according to the welding surface of the pipe, and thus ensuring the stability and practicability of welding.

[0012] 3. When the welding surfaces of the two symmetrically arranged left and right butt joint pipes are butted in the present utility model, since the welding cavity is connected to the outside at this time, it is ensured that the two butt joint pipes on the butt joint surface are exposed to the outside, so as to ensure that subsequent welding can be directly carried out, without the need for turning over, thus ensuring that welding is completed at one time and further improving the welding efficiency.

[0022] Embodiment 1

[0023] Referring to Figures 1-6 , it is the first embodiment of the present utility model. This embodiment provides an embodiment of a welding platform for municipal engineering construction, including a main box body 11. An upwardly open welding cavity 26 is provided inside the main box body 11. Two groups of upwardly open and left-right symmetric rotating cavities 14 are provided inside the main box body 11. A rotating shaft 16 is rotatably provided between the front and rear walls of the rotating cavity 14. A rotating frame 17 is fixedly provided on the outer circumferential surface of the rotating shaft 16. Further, the rotating frame 17 plays a role in adjusting according to the angle of the welding surface of the pipeline. A pushable frame 21 that can move back and forth is provided above the rotating frame 17. A positioning cavity 27 with an upward opening is provided inside the pushable frame 21. An arc-shaped groove is provided on the lower wall of the positioning cavity 27, thereby ensuring the stability of the pipeline. A plurality of groups of clamping frames 24 that can move towards each other and are evenly distributed in the front, rear, left, and right directions are provided inside the positioning cavity 27. Further, the clamping frames 24 play a clamping role.

[0024] A plurality of groups of threaded sliders 23 that are evenly distributed left and right are rotatably provided on the front and rear end faces of the pushable frame 21. A threaded shaft 22 that can move back and forth is provided on the outer circumferential surface of the threaded slider 23. The threaded shaft 22 is in threaded cooperation with the threaded slider 23. The upper end face of the threaded shaft 22 is fixedly connected to the clamping frame 24. A docking pipe 25 is provided above the pushable frame 21.

[0025] A driving cavity 28 connected to the outside is provided inside the rotating frame 17. A driving shaft 19 is rotatably provided between the left and right walls of the driving cavity 28. A driving slider 20 capable of moving left and right is provided on the outer circumferential surface of the driving shaft 19. The upper end surface of the driving slider 20 is fixedly connected to the driving frame 21. A driving motor 18 is fixedly provided inside the rotating frame 17.

[0026] A rotating motor 15 is fixedly provided inside the rear wall of the rotating cavity 14. The rear end surface of the rotating shaft 16 is power-connected to the rotating motor 15.

[0027] A counterweight 12 is fixedly provided on the lower end surface of the main box body 11. Thus, the counterweight 12 plays a role of counterweight. A controller 13 is fixedly provided on the upper end surface of the front side of the main box body 11. Thus, the controller 13 plays a role of coordinating various movements.

[0028] Specific working process:

[0029] During use, at this time, the butt joint pipe 25 to be welded is placed above the driving frame 21 and located in the groove, and the welded part of the butt joint pipe 25 should be in the welding cavity 26. At this time, the user rotates the butt joint pipe 25 to ensure that the surface to be welded faces upward. At this time, the user starts to rotate the front and rear symmetric threaded sliders 23 simultaneously and repeats from left to right in sequence. At this time, since the threaded slider 23 is in threaded cooperation with the threaded shaft 22, the front and rear symmetric clamping frames 24 are pushed to move towards each other, thereby realizing the clamping and fixing of the butt joint pipe 25. And because there are multiple groups of clamping frames 24, the clamping and fixing of multiple points on the outer circumferential surface of the butt joint pipe 25 are realized.

[0030] At this time, according to the angle of the welding surface of the butt joint pipe 25, the left and right symmetric rotating motors 15 are started. At this time, the rotating shaft 16 starts to rotate, thereby driving the rotating frame 17, the driving frame 21, and the clamped pipe to rotate until the two left and right symmetric butt joint pipes 25 and the welding surfaces reach the horizontal position. At this time, the driving motors 18 are respectively controlled to start, and the driving shaft 19 starts to rotate, thereby driving the driving slider 20, the driving frame 21, and the clamped pipe to move towards each other.

[0031] At this time, when the welding surfaces of the two left and right symmetric butt joint pipes 25 are butted, since the welding cavity 26 is connected to the outside, the two butt joint pipes 25 on the butting surface are ensured to be exposed to the outside.

[0032] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
