A high-stability pipeline welding robot

Abstract

The utility model relates to the technical field of pipeline welding, and discloses a high-stability pipeline welding robot, comprising a trackless magnetic trolley, a welding head adjustment frame and an anti-dropping belt. A stabilizing adsorption part is installed in a trolley shell of the trackless magnetic trolley, and the trolley shell is adsorbed on the pipeline through the stabilizing adsorption part. When moving, the trackless magnetic trolley is driven to move by a driving wheel to ensure that the trackless magnetic trolley will not fall from the pipeline while moving around the pipeline. Compared with a welding robot using a track, since there is no gap at a track joint, the trackless magnetic trolley is directly adsorbed on the pipeline for movement, so that the welding of the pipeline is more stable.

Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a high-stability pipeline welding robot. Background Art

[0002] Pipes are used in a wide range of areas, such as water conservancy projects. Most water conservancy projects are carried out outdoors. In the construction of water conservancy projects, metal pipes are often used. When laying metal pipes, the pipe joints need to be welded. Manual welding takes a long time and has low efficiency. At present, in order to improve welding efficiency, pipe welding robots are used for welding.

[0003] When using the existing rail-type pipeline welding robot, the track needs to be installed on the pipeline before it can be used. There will be gaps at the joints of the tracks. When the welding robot moves around the pipeline on the track and passes through the gaps, there will be instability that will affect the welding effect. There is an urgent need for a high-stability pipeline welding robot. Utility Model Content

[0033] Reference Figure 1-4 As shown, the utility model provides a high-stability pipeline welding robot, comprising:

[0034] The trackless magnetic trolley 100 includes a trolley housing 110 and a driving wheel 120 installed at the lower end of the trolley housing 110. A stable adsorption portion 130 for adsorbing on a pipeline is installed in the trolley housing 110;

[0035] The welding head adjustment frame 200 includes a sliding sleeve frame 210 fixedly welded to one side of the trolley housing 110 and a welding head cover 220 fixedly installed on the sliding part of the sliding sleeve frame 210, and a welding head 230 is detachably installed in the welding head cover 220;

[0036] The anti-dropping belt 300 has one end fixedly connected to one end of the trolley housing 110 , and the other end is detachably mounted on the other end of the trolley housing 110 by passing under the pipeline.

[0037] The stable adsorption part 130 is installed in the trolley shell 110 of the trackless magnetic trolley 100, and the trolley shell 110 is adsorbed on the pipeline through the stable adsorption part 130. When moving, the trackless magnetic trolley 100 is driven to move by the driving wheel 120 to ensure that the trackless magnetic trolley 100 will not fall off the pipeline while moving around the pipeline. Compared with the welding robot using tracks, since there is no gap at the joint of the track, the trackless magnetic trolley 100 is directly adsorbed on the pipeline for movement, making the welding of the pipeline more stable.

[0038] As a further preferred embodiment of the above embodiment, the trolley housing 110 is a component made of high temperature resistant plastic material.

[0039] Heat dissipation grids 111 are installed at both ends of the trolley housing 110 , a lifting ring 112 is connected to the upper end of the trolley housing 110 , and an installation cavity 113 is provided inside the trolley housing 110 .

[0040] As a further preferred embodiment of the above embodiment, the stable adsorption portion 130 is installed in the installation cavity 113, and the stable adsorption portion 130 is an electromagnet.

[0041] By supplying power to the electromagnet, the trackless magnetic trolley 100 is adsorbed on the pipeline, and by controlling the strength of the power supply current to the electromagnet to control the magnetic strength of the electromagnet, the driving wheel 120 drives the trackless magnetic trolley 100 to move more smoothly, ensuring that the trackless magnetic trolley 100 will not fall off the pipeline while moving around the pipeline, making the welding of the pipeline more stable.

[0042] The stable adsorption part 130 can also be a neodymium magnet. The neodymium magnet has strong magnetic attraction and can ensure that the trackless magnetic attraction trolley 100 is adsorbed on the pipeline, but the magnetic strength cannot be controlled. It is inconvenient for the trackless magnetic attraction trolley 100 to move on the pipeline through the driving wheel 120.

[0043] As a further preferred embodiment of the above embodiment, the driving wheel 120 includes a wheel column 121 rotatably mounted on the lower end of the trolley housing 110 and a servo motor 122 fixedly mounted on the trolley housing 110 , and a driving end of the servo motor 122 is connected to one end of the wheel column 121 .

[0044] Furthermore, a magnetic core 101 is disposed in the wheel column 121 .

[0045] As a further preferred embodiment of the above embodiment, the sliding sleeve frame 210 includes a transverse guide rod 211 fixedly connected to one side of the trolley housing 110 and a sliding sleeve 212 movably sleeved on the transverse guide rod 211 , and a first fixing bolt 213 is threadedly installed on the side surface of the sliding sleeve 212 .

[0046] The welding head sleeve 220 includes a mounting block 221 mounted on the sliding sleeve 212 by screws and a sleeve 222 fixedly welded to one end of the mounting block 221 . A second fixing bolt 223 is threadedly mounted on the side of the sleeve 222 . The welding head 230 is movably inserted into the sleeve 222 .

[0047] When in use, the position of the sliding sleeve 212 on the transverse guide rod 211 can be moved and adjusted according to welding needs, so that the welding head sleeve 220 can be moved and adjusted laterally, and the welding head 230 can move up and down relative to the sleeve 222, which is convenient for adjusting the distance between the welding head 230 and the pipe welding point.

[0048] The anti-drop belt 300 includes a canvas belt 310 fixedly connected to the trolley housing 110 at one end and a socket block 320 fixedly connected to the other end of the trolley housing 110 , and a third fixing bolt 330 is threadedly installed on the socket block 320 .

[0049] One end of the anti-drop belt 300 is fixedly connected to one end of the trolley shell 110, and the other end is detachably installed on the other end of the trolley shell 110 by passing under the pipeline. The anti-drop belt 300 and the trolley shell 110 form a closed loop on the pipeline, so that the trackless magnetic trolley 100 will not fall directly to the ground when it accidentally falls from the pipeline, and can be protected.

[0050] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
