[0025] See also Figure 1-5 The utility model provides a technical solution: a marking device for auxiliary steel pipe processing, comprising: a main base 1, a placing mechanism, an auxiliary mechanism and a marking mechanism; the auxiliary mechanism comprises a sub-base 2 and a plug-in plate 9, the main base 1 and the sub-base 2 are both provided with a placing mechanism on the top, the placing mechanism comprises a placement frame 3 and two symmetrical auxiliary wheels 4, the round steel pipe is placed by the two auxiliary wheels 4 so that it can rotate stably during marking, the outer wall of the main base 1 is provided with a marking mechanism, the marking mechanism comprises an electric hook wire spray gun 15, the steel pipe placed by the placing mechanism is marked by the electric hook wire spray gun 15, a slot is provided at one end of the main base 1, the plug-in plate 9 is fixedly connected to one end of the sub-base 2, the plug-in plate 9 is plugged into the slot of the main base 1, and a plug-in rod 6 is plugged between the plug-in plates 9 of the main base 1 and the sub-base 2;

[0026] There are two placing mechanisms on the top of the main base 1, and there is a placing mechanism on the top of the sub-base 2. The two auxiliary wheels 4 of the placing mechanisms are symmetrically arranged, and can jointly lift and assist the rotation of the round steel pipe through the two auxiliary wheels 4 of the placing mechanisms. When the steel pipe placed on the placing mechanism is rotating, the electric hook line spray gun 15 can be used to circle and mark. The electric hook line spray gun 15 is provided with an ink cartridge to store the sprayed ink. After the external control power supply is powered on, it sprays vertically downward. The plug plate 9 of the sub-base 2 is plugged into the slot of the sub-base 2, and it is not easy to fall out after being plugged in by the plug rod 6, so that the sub-base 2 is neat and not easy to lose when stored. When the length of the steel pipe is too long and too heavy, one end of the plug rod 6 can leave the plug plate 9 to separate the sub-base 2 from the main base 1, and assist the main base 1 to jointly lift the two ends of the long steel pipe.

[0027] Preferably, a mounting seat 5 is fixedly connected to the top of the main base 1 around one end of the insertion rod 6, and a spring 7 is fixedly connected to the mounting seat 5 and one end of the insertion rod 6 extending out of the main base 1;

[0028] One end of the plug rod 6 and the spring 7 of the mounting seat 5 are in a retracted state in the absence of external force, so that the plug rod 6 can be more stably plugged into the plug board 9 and is not easy to fall out of the slot of the main base 1, so that the auxiliary base 2 can be relatively stably spliced ​​with the main base 1, and the spring 7 is stretched when the plug rod 6 is pulled.

[0029] Preferably, the two auxiliary wheels 4 in the placement mechanism are rotatably connected to the top of the placement frame 3;

[0030] Two auxiliary wheels 4 rotate on the top of the placement frame 3, and the round steel pipe can be placed between the two auxiliary wheels 4 to assist the round steel pipe to rotate.

[0031] Preferably, the marking mechanism further includes an electromagnet 11, a support rod 12, a sliding sleeve 13 and a crossbeam 14. The outer wall of the main base 1 is provided with a sliding groove 10, and the electromagnet 11 slides in the sliding groove 10;

[0032] The electromagnet 11 of the marking mechanism can slide in the slide groove 10 of the main base 1 when the power is off, and the external control power supply assists in adjusting the position of the electric hook wire spray gun 15. After power is connected, the magnetic end of the electromagnet 11 will attract the iron main base 1 and the slide groove 10, so that the electric hook wire spray gun 15 is stabilized in the adjusted position.

[0033] Preferably, the electromagnet 11 is fixed to one end of the support rod 12, the outer wall of the support rod 12 is slidably connected with a sliding sleeve 13, and the crossbeam 14 is fixedly connected to the outer wall of the sliding sleeve 13;

[0034] The sliding sleeve 13 can slide up and down on the support rod 12 to adjust the up and down positions of the crossbeam 14 and the components installed on the crossbeam 14.

[0035] Preferably, the electric hook wire spray gun 15 is fixed to one end of the crossbeam rod 14, and a plurality of adjusting thread grooves 16 are sequentially opened on the outer wall of the support rod 12, and a hand-tightening bolt 17 is threadedly connected between the sliding sleeve 13 and one of the adjusting thread grooves 16 of the support rod 12;

[0036] The spray end of the electric hook wire spray gun 15 is vertically downward, and it can be adjusted up and down together with the crossbeam 14. When the sliding sleeve 13 slides on the support rod 12 to adjust the position of the electric hook wire spray gun 15, a suitable adjustment thread groove 16 can be selected according to the position, and one end of the hand-tightening bolt 17 can be connected to the sliding sleeve 13 to tighten it.

[0037] Preferably, the main base 1 is provided with length scale lines along the outer wall of the slide slot 10;

[0038] The length scale lines arranged along the slide groove 10 are used to assist the support rod 12 attached to the length scale lines to accurately adjust the position.

[0039] Preferably, one end of the insertion rod 6 is fixedly connected with a pull ring 8;

[0040] The pull ring 8 is used to facilitate personnel to pull the insertion rod 6 so that one end of the insertion rod 6 is separated from the insertion plate 9 of the auxiliary base 2.

[0041] A specific application of this embodiment is: the round steel pipe can be placed on the two placement mechanisms of the main base 1 and the one placement mechanism of the auxiliary base 2. The symmetrical auxiliary wheels 4 of the placement mechanisms can be manually turned to make the steel pipe rotate stably. At the same time, the electric hook line spray gun 15 sprays ink vertically downward toward the rotating steel pipe, so that the marking operation is completed after one circle of rotation. According to the thickness of the steel pipe, the sliding sleeve 13 of the support rod 12 can be slid, and the upper and lower positions of the electric hook line spray gun 15 can be adjusted by using the cooperation of the hand-tightening bolt 17 and the adjusting thread groove 16, so that the spraying distance is better within the appropriate range;

[0042] When marking the steel pipe, the position of the electric hook line spray gun 15 can be adjusted according to the needs of the marking position. After the power supply of the electromagnet 11 is disconnected, the electromagnet 11 is slid in the slide groove 10 of the main base 1, and the position of the electric hook line spray gun 15 of the support rod 12 and the crossbeam rod 14 can be adjusted at the same time. While adjusting the position, the support rod 12 is used in conjunction with the length scale line set along the slide groove 10 to make precise position adjustment;

[0043] The auxiliary base 2 at one end of the main base 1 can be split according to the length of the round steel pipe. The plug rod 6 is pulled away from the plug plate 9 of the auxiliary base 2 through the pull ring 8, and the plug plate 9 can be pulled out of the slot of the main base 1. The placement mechanism on the top of the auxiliary base 2 is used to lift the other end of the longer steel pipe that does not need to be marked, so as to avoid the steel pipe being too long and too heavy, causing the end that needs to be marked to tilt and affect the marking.
