Description

Technical Field

[0001] The invention relates to the field of steel pipe processing and production, and in particular to a multifunctional steel pipe conveying device and a system thereof. Background Art

[0002] In steel pipe production lines, due to the connection and transportation process requirements between different stations and processes, it is often necessary to realize the feeding, discharging, alignment and rotation functions of steel pipes between different stations. Generally, only one of the functions needs to be realized at a certain station or between different stations. For example, only the feeding and discharging of steel pipes needs to be realized between two stations, and only the alignment or rotation of steel pipes needs to be realized at a certain station. However, in some more complicated cases, two or three of the functions need to be realized at one station. For example, in a water pressure testing machine, the feeding, discharging, alignment and rotation flushing functions of steel pipes need to be realized at one station before the main machine is fed. Among the existing equipment, most can only realize one function at one station, very few can realize two functions at one station, and almost no can realize three functions at one station.

[0024] A base frame 4, the rotating mechanism 2 is detachably connected to the base frame 4, and the feeding and discharging mechanism 1 and the alignment lifting roller 3 are respectively arranged on both sides of the base frame 4;

[0025] The left adjustment mechanism and the right adjustment mechanism, the feeding and discharging mechanism 1 and the alignment lifting roller 3 are connected to both sides of the base frame 4 through the left adjustment mechanism and the right adjustment mechanism respectively, and the left adjustment mechanism and the right adjustment mechanism have the same structure;

[0026] A pair of driving mechanisms, the left adjusting mechanism and the right adjusting mechanism are respectively connected to the driving mechanisms.

[0027] In actual use: when the rotating mechanism 2 is used, the top ends of the feeding and discharging mechanism 1 and the alignment lifting roller 3 are lower than the rotating mechanism 2 , so that the feeding and discharging mechanism 1 and the alignment lifting roller 3 will not be blocked when the rotating mechanism 2 is used.

[0028] When using the feeding and discharging mechanism 1, start the driving mechanism connected to the left adjusting mechanism, so that the driving mechanism drives the left adjusting mechanism to rise, so that the feeding and discharging mechanism 1 rises. At this time, the top of the rotating mechanism 2 and the alignment lifting roller 3 are lower than the feeding and discharging mechanism 1, and then the feeding and discharging mechanism 1 can be used.

[0029] When using the alignment lifting roller 3, start the driving mechanism connected to the right adjusting mechanism, so that the driving mechanism drives the right adjusting mechanism to rise, so that the alignment lifting roller 3 is raised. At this time, the top of the rotating mechanism 2 and the feeding and discharging mechanism 1 are lower than the alignment lifting roller 3, and then the alignment lifting roller 3 can be used.

[0032] In actual use: the driving mechanism pushes one end of the control rod 9, and the other end of the control rod 9 is connected to the rotating shaft 7, so that the control rod 9 drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 mobilizes a pair of upper connecting rods 5 to rotate, driving the lifting frame 8 to rise. At the same time, the two ends of a pair of lower connecting rods 6 are respectively hinged to the base frame 4 and the lifting frame 8 to form a limit for the lifting frame 8. With the action of the upper connecting rod 5, the lifting frame 8 can maintain a vertical state when rising. When the lifting frame 8 descends, the driving mechanism can be driven in the reverse direction.

[0038] In actual use: the driving member pushes and pulls the driving rod 11, and the driving rod 11 pushes one end of the control rod 9 through the driving connecting member 12, so that the control rod 9 can rotate.
