Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, in particular to a building fire protection pipeline welding device. Background Art

[0002] Building fire protection pipes are an important part of the interior of a building. They are used to transport large amounts of water or other fire extinguishing agents to various areas within the building for use by firefighting equipment to respond to emergencies such as fires. Fire protection pipes are usually connected by threaded connection, flange connection or welding connection. Fire protection pipes are connected by welding. Usually, the fire protection pipes are placed on a welding device, and the ends of the fire protection pipes are brought into contact before welding.

[0003] After searching, the authorization announcement number CN212384953U and the authorization announcement date 2021.01.22 disclose a building fire protection pipe welding device, which includes a base plate, a bracket, a tube fixing plate, a pipe and a back plate; the top of the base plate is fixed with a limit plate, a bracket, a rod fixing plate and a frame in sequence, and the bracket and the rod fixing plate are each provided with two groups, and the top of the bracket is connected to the tube fixing plate, and the top of the tube fixing plate is provided with a pipe groove, and there are multiple groups of pipe grooves, and a sliding rod is fixed inside the rod fixing plate, and there are two groups of sliding rods; the sliding rod is inserted into the inside of the rod hole, and the rod hole is provided inside the back plate, and an electric push rod is provided at the top of the frame, and the push rod end of the electric push rod is connected to the side wall of the back plate, and bearings are provided at the inner wall of the limit plate and the back plate, and there are multiple groups of bearings, and a turntable is provided on the outer wall of the bearing. The utility model can press the pipes to be welded by the abutment plate, so that the pipes are abutted against each other, and the ends of the pipes are fitted on the outer wall of the turntable. During the welding process, it is beneficial to drive the welding point to rotate, which greatly improves the convenience of welding.

[0004] The prior art places two pipes on a pipe plate and adjusts the welding position by rotating a turntable. However, in actual use, since the pipes and the pipe plate are in contact with each other during welding position adjustment, abnormal wear of the pipe plate and the fire pipe will be caused, which reduces the service life. In addition, smoke and dust generated during welding in the prior art drift into the operating environment, causing pollution to the operating environment. Therefore, we provide a building fire pipe welding device to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a building fire protection pipe welding device, which avoids abnormal wear caused by friction when the pipe body rotates through the relative rolling of the roller and the pipe body, and purifies the smoke through the activated carbon filter plate to avoid the smoke from polluting the operating environment, thereby solving the problem that the welding position of the pipe and the fixed pipe plate in the prior art is adjusted in a contact state, which will cause abnormal wear of the fixed pipe plate and the fire protection pipe and reduce the service life, and the smoke generated during welding in the prior art is scattered to the operating environment, causing pollution to the operating environment.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a building fire protection pipeline welding device, comprising a pipeline body, two pipeline bodies are provided, and the inner ends of the pipeline bodies are abutted, and a welding assembly is provided on the outside of the pipeline body, and the welding assembly comprises a bottom plate, and electric push rods are fixed on the left and right sides of the upper wall of the bottom plate, and a moving frame is fixed on the upper end of the electric push rod, and rollers are provided on the front and rear sides of the left end of the moving frame and the front and rear sides of the right end of the moving frame;

[0008] A purification assembly is arranged on the rear side of the welding assembly, and the purification assembly comprises a box body, a fan is fixed on the lower side of the rear wall of the box body, an activated carbon filter plate is arranged inside the box body, and a box cover is fixed to the upper wall of the box body by bolts.

[0009] The utility model is further configured that guide sleeves are fixed to the upper wall of the bottom plate corresponding to the left and right sides of the electric push rod, guide rods are provided in the internal clearance of the guide sleeves, and the guide rods are fixedly connected to the moving frame.

[0010] The utility model is further configured such that bosses are fixed on both left and right ends of the upper wall of the movable frame, a protrusion is fixed on the inner side wall of the boss, and the roller is rotatably connected to the protrusion, an anti-slip sleeve is fixed on the outside of the roller, and the anti-slip sleeve is in contact with the corresponding pipe body.

[0011] The utility model is further configured that a mounting plate is fixed to the rear side of the base plate, a mounting frame is fixed to the front side of the mounting plate, and a rotating rod is rotatably connected to the lower side of the mounting frame through a bearing.

[0012] The utility model is further configured such that rotating wheels are fixed on both sides of the left and right sides of the rotating rod, anti-slip rings are fixed on the outer peripheral walls of the rotating wheels, and the outer peripheral walls of the anti-slip rings abut against the corresponding pipe body, a motor is fixed on the right wall of the mounting frame, and the power output shaft of the motor is fixedly connected to the rotating rod.

[0013] The utility model is further configured such that a circular strip is provided along the edge of the lower wall of the activated carbon filter plate, and the circular strip is fixedly connected to the box body, an air outlet is opened at the rear wall of the box body corresponding to the position of the fan, and a protective net is fixed to the rear wall of the fan.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model is provided with an electric push rod and a roller. In the use state, since the roller can rotate relative to the protrusion, when the motor is working, the anti-slip ring rotates to drive the two pipe bodies to rotate. At this time, the roller and the anti-slip sleeve both rotate relative to the pipe body. Compared with the prior art, since the pipe body and the roller rotate synchronously, the pipe body rotates by static friction, thereby avoiding abnormal wear of the pipe body and the phenomenon of shortening the service life due to abnormal wear. This solves the problem that in the prior art, the welding position adjustment of the pipe and the fixed pipe plate in the contact state will cause abnormal wear of the fixed pipe plate and the fire-fighting pipe, thereby shortening the service life.

[0017] 2. The utility model sets an activated carbon filter plate and a fan, and generates an airflow through the fan to suck the smoke generated during welding into the interior of the box. The activated carbon filter plate filters the smoke to achieve a purification effect, while preventing the smoke from drifting into the operating environment, thereby preventing the pollution of the operating environment caused by the smoke. This solves the problem of the prior art that the smoke generated during welding drifts into the operating environment, causing pollution to the operating environment.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
