The jacking device 1 is a hydraulic jacking device.

The L-shaped support platform 102 is fixed to the top of the ejector rod of the lifter 101 by bolts 104.

The support rod 103 is cylindrical.

A base 105 is fixed at the bottom of the jacking device 101, and a mounting hole 106 is formed in the base 105.

The paint spraying openings 205 arranged on the inner sides of the upper semi-annular pipe 201 and the lower semi-annular pipe 202 are uniformly distributed on the inner sides of the upper semi-annular pipe 201 and the lower semi-annular pipe 202 respectively.

The working principle of the invention is as follows:

before the steel pipe lifting device is used, two lifting mechanisms are symmetrically arranged on the ground according to the length of a steel pipe, and the specific installation method comprises the following steps: the base 105 is installed on the ground by fastening screws through the installation holes 106.

When the steel pipe painting device is used, firstly, the annular painting pipe 3 of the painting device is sleeved on the outer side of the steel pipe, then the steel pipe is lifted, an opening at one side of the steel pipe is sleeved on one supporting rod 103, then, an opening at the other side of the steel pipe is sleeved on the other supporting rod 103, then, the steel pipe is moved to the middle position between the two supporting rods 103, so that the two ends of the steel pipe are sleeved on the supporting rods 103 to form supports for the steel pipe, at the moment, the steel pipe can be painted by the painting device, after painting is finished, the steel pipe is lifted, the two ends of the steel pipe are sequentially taken down from the two supporting rods 3, the steel pipe can be put down after the painting device is dismounted, and at the moment.

The use method of the annular paint spraying pipe 3 comprises the following steps:

the steel pipe to be painted is sleeved in the middle of the upper semi-annular pipe 201 and the lower semi-annular pipe 202, and then the upper semi-annular pipe 201 and the lower semi-annular pipe 202 are fixed through the bolts 203, so that the paint spraying device is easily sleeved outside the steel pipe, does not need to be sleeved from two ends of the steel pipe, can be operated at any position of the steel pipe, and is very convenient to use.

The working principle of the paint spraying device is as follows:

when in use, the paint liquid is poured into the paint storage tank 9, and then the auxiliary wheel 8 and the driving roller 6 are pressed on the steel pipe simultaneously; next, when the steel pipe is not in the middle of the annular paint spraying pipe 3, the annular paint spraying pipe 3 locks the adjusting block at different positions of the adjusting groove 21 through the locking nut group so that the steel pipe can always pass through the central position of the annular paint spraying pipe 3; then holding the grab handle to roll on the surface of the steel pipe, driving the roller 6 to drive the rotating shaft 61 to rotate, the cam 63 at the front end of the rotating shaft 61 continuously and reciprocally presses against the impact sheet, meanwhile, the impact sheet overcomes the elasticity of a compression spring and drives the air pressing sheet to continuously push the air in the reciprocating air cylinder 4 into the air storage cavity through the piston rod, and meanwhile, the air inlet valve and the air outlet valve respectively tend to re-press the air in the air cylinder 4 and the air storage cavity for air inlet and air outlet; at the moment, the gas enters the paint storage tank 9 through the gas inlet pipe 44, and paint liquid in the paint storage tank 9 reaches the annular paint spraying pipe 3 through the paint inlet pipe 7 under the pressure of air pressure and is sprayed out from the spray head.

Finally, it should be noted that the above-mentioned list is only the specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
