Description

Technical Field

[0001] The utility model relates to the technical field of material unloading trolleys, in particular to a fully automatic material unloading trolley. Background Art

[0002] When a pipeline is partially damaged and needs to be repaired or replaced, it is often necessary to cut the pipeline. Flame cutting is currently a very economical and efficient cutting method and is widely used. The automated cutting trolley usually uses a mechanical track limiter and is fixed to the pipeline under the pressure of a chain. The flame cutting gun head and the pipeline are adjusted to the required angle. After the cutting flame cuts through the pipe wall, it crawls circumferentially under the drive of the travel motor, thereby completing the circumferential cutting of the pipeline.

[0003] Mechanical rails can be divided into contact and non-contact types according to whether the running wheels are in contact with the outer cylindrical surface of the pipe. In the contact type mechanical rail, the rail only serves to limit the running wheels, and the rail does not bear the direct force of the running wheels; in the non-contact mechanical rail, the running wheels act directly on the outer cylindrical surface of the rail, and the rail is fixed to the outer cylindrical surface of the pipe through support legs.

[0004] However, the current contact mechanical tracks and non-contact mechanical tracks have the following problems:

[0005] 1. The contact type mechanical track only serves as an axial limit for the trolley and does not bear the force of the trolley. The walking wheels directly press on the outer surface of the pipe and crawl circumferentially. The movement of the trolley is affected by the outer surface of the pipe, and the walking track accuracy is not good. In particular, the pipe weld will directly affect the movement of the trolley and have an adverse effect on cutting.

[0006] 2. Because the non-contact mechanical track needs to bear the radial force of the trolley, it is large in size and heavy in weight, which is not convenient to carry and operate. The contact part of the running wheel on the track is easy to deform, and the accuracy is poor after long-term use.

[0007] 3. The electronic control system adopts a split type, that is, the controller is independently connected to the trolley through a control cable. The electronic control system is large in size, and the on-site installation operation is more complicated. The electronic control system is easily affected by environmental magnetism and has poor stability. There are many cables and the failure rate is high under on-site working conditions.

[0008] 4. The trolley is heavy and usually requires two people to complete the installation of the trolley.

[0009] Therefore, a fully automatic unloading trolley is proposed to address the above problems. Utility Model Content

[0034] (1) During installation, the handle of the adjustment handle 17 is inserted downward into the L-shaped positioning plate 18 below. At this time, the adjustment handle 17 and the pressure rod 19 are vertically arranged. The pressure spring 22 is compressed by the coordinated action of the pressure rod 19 and the connecting rod 21.

[0040] Specifically, the rotating shaft 32 is inserted into the interior of the U-shaped mounting frame 5 from one end of the U-shaped mounting frame 5, and extends to the outside of the other end of the U-shaped mounting frame 5 to be connected to the positioning member 33. When the angle is tilted, the axis of the rotating shaft 32 is located on the cylindrical center line of the cutting gun head 8. By loosening the fastening bolt 7, it is easy to install and adjust the extended length of the cutting gun head 8, and then the distance between the gun head and the pipe surface can be adjusted without affecting the actual cutting size.

[0041] Specifically, the pressure rod 19 and the connecting rod 21 are arranged vertically.

[0042] Specifically, the driving wheel 15 is provided with hard fine teeth on the outside. The hard fine teeth on the driving wheel 15 will form small fine teeth on the inner side of the track 30 at the initial stage of walking, so that the hard fine teeth on the driving wheel 15 can mesh with the small fine teeth formed on the inner side of the track 30, ensuring the stability of the unloading trolley during long-term use.
