Description
Technical field
The utility model belongs to technical field of mechanical processing, and in particular to a kind of large-scale pipeline semi-automatic welding swivel mount.
Background technique
In field of machining, welding is one of most common processing method, using especially more in pipeline connection.It is existing
Welding procedure in, to large-scale pipeline, (1 meter of diameter or more, 8 meters of length or less pipeline also includes the cylindrical work of 0.3 ~ 1 meter of diameter
Part end face) when carrying out operation, usual personnel station carries out climbing weldering to weld seam in side, since personnel's arm length is limited, every weldering
Connecing one meter or so of weld seam will stop, and personnel station carries out the rotation of a pipeline in pipeline side using crowbar, by what is welded
Part goes to top, and the position that the weld seam not welded goes to personnel's arm and can get at continues to weld, due to climbing
Welding line is approximately perpendicular to ground, if welding current is big, base material thawing is too fast, and molten bath can be downward along weld seam by gravity
Trickling, causes welding defect, therefore welding current need to be controlled in 115A or so, and welding current is small, and base material and welding wire melt slow, weldering
Low efficiency is connect, and welds large labor intensity, safety is lower.
Therefore, a kind of auxiliary machine tool for large-scale pipeline welding is needed.
Utility model content
It is in the prior art to solve the purpose of the utility model is to provide a kind of large-scale pipeline semi-automatic welding swivel mount
Welding efficiency is low, and welds large labor intensity and the lower problem of safety.
The utility model is achieved by the following technical solution: a kind of large-scale pipeline semi-automatic welding swivel mount, including
Pedestal, the driving roller and driven roller of support pipeline；Driving roller is fixed on chassis by bearing block, and driven roller passes through
Mobile device is slipped on chassis；
The drive shaft of the driving roller is connected by speed reducer with driving motor；
The mobile device includes the mounting bracket being fixed on chassis, and twice strip bolt is provided in mounting bracket
The bearing block of mounting groove, driven roller is bolted on mounting groove；
It further include the operating platform slipped with chassis.
Further: the operating platform includes the castor with brake gear, the main platform body being crossed on above pipeline,
Be spirally connected fixation on the downside of castor and main platform body.
It is further: to be equipped with mutually matched rack gear on mounting bracket top and the bearing block lower part of driven roller.
The beneficial effects of the utility model are: the utility model structure effective solution pipeline welding current is small, welding
The problem of low efficiency.By improving welding current to improve speed of welding.Using large-scale pipeline semi-automatic welding swivel mount,
Enable pipeline to require at the uniform velocity to rotate according to technique, while moveable operating platform is set, personnel are on platform to pipeline
Surface is welded, welding manner from personnel stand pipeline side carry out climbing weldering become personnel carried out above pipeline it is flat
Weldering, weld seam is parallel to the ground, and downhand welding is since molten bath will not be because being trickled by gravity along weld seam, and welding current can increase at this time
165A or so is arrived, welding current is big, and base material and welding wire melt faster, and speed of welding significantly improves.

Road.
Specific embodiment
It is as shown in Figs 1-4 a kind of large-scale pipeline semi-automatic welding swivel mount of the utility model, including pedestal 1, support pipe
The driving roller 4 and driven roller 3 in road；Driving roller is fixed on chassis by bearing block 2, and driven roller passes through mobile device
It slips on chassis；
The drive shaft of the driving roller is connected by speed reducer 6 with driving motor 9, between drive shaft and speed reducer
It is additionally provided with shaft coupling 5, shaft coupling 7 is provided between speed reducer and driving motor；Preferably, in driving motor and shaft coupling 7
Between be additionally provided with cycloidal planetary gear speed reducer 8；
The mobile device includes the mounting bracket being fixed on chassis, and twice strip bolt is provided in mounting bracket
The bearing block of mounting groove, driven roller is bolted on mounting groove；
It further include the operating platform slipped with chassis.
Preferred: the operating platform includes the castor 10 with brake gear, the platform body being crossed on above pipeline
11, be spirally connected on the downside of castor and main platform body fixation, and castor can slide on the track 12 being fixed on the base.
It is preferred: to be equipped with mutually matched rack gear on mounting bracket top and the bearing block lower part of driven roller.
Preferred: side is equipped with several openings on the operational platform, is equipped with cover board in overthe openings.
Preferred: the driving roller and driven roller are taper type, the side circumference (diameter) close to welding position
Less than the other side.
The utility model arrangement works process is as follows, for when this structure is for the manufacture welding of φ 2820mm gas piping
Illustrate, the every trifle of gas piping is rolled into using 2 meters of wide steel plates, and three trifles are welded into a big section, as shown in figure 3, firstly, by three
It after the small accurate butt welding in spot of length of tubing is secured, is put on large-scale pipeline semi-automatic welding swivel mount using crane, then will be stopped
Mobile platform in side is moved to central location, and two welders on ladder through arriving above platform, in platform two sides middle position
Simultaneously to welding right above two weld seams of pipeline, personnel are motionless, pipeline rotation, the controllable tubing giving sufficient strength of controller in welder's hand
Rotation speed, weld seam rotation speed 1.2mm/s.Welding current is up to 165A or so, about 4 meters of weld seam/hours of speed of welding at this time
× 2 weld seam=8 meter weld seams/hour.3.5 meters of weld seam/hours of speed of welding when before comparison using climbing weldering, speed improve
2.28 again.After welding, operating platform is moved to the side of device, by soldered pipeline handling to finished product area,
Then the first step is repeated, the pipeline connected is put on device by next.
