Detailed Description

The invention is described in further detail below with reference to specific embodiments and with reference to the attached drawings.

Example 1

As shown in fig. 1-2, a progressive pressurization type steel pipe paint spraying apparatus comprises a paint spraying apparatus and a placing rack, wherein the placing rack comprises symmetrically arranged lifting mechanisms, each lifting mechanism comprises a jacking device 101 and an L-shaped supporting platform 102 fixed at the top of a jacking rod of the jacking device 101, a horizontally arranged supporting rod 103 is fixed on the inner side of the upper part of the L-shaped supporting platform 102, and the paint spraying apparatus comprises a fixing frame 1, an adjusting base frame 2, a reciprocating air cylinder 4 and a paint storage tank 9 as a main body; an auxiliary wheel 8 and a driving roller 6 are arranged on one side of the fixed frame 1, and the driving roller 6 penetrates through the fixed frame 1 and is provided with a rotating shaft 61 fixedly connected with the rotating shaft and a cam 63 fixed at one end of the rotating shaft 61; a reciprocating air cylinder 4 and a paint storage tank 9 which are fixedly connected are respectively arranged on two sides of the fixed frame 1, which are positioned at the rear end of the driving roller 6, the rear end of the reciprocating air cylinder 4 is provided with an air storage cavity and an air outlet valve, and the rear end of the air storage cavity is provided with an air inlet pipe 44 which is connected with the paint storage tank 9; the rear end of the fixing frame 1 is provided with an adjusting base frame 2 and an annular paint spraying pipe 3, an adjusting groove 21 and an adjusting block which is matched with the adjusting groove 21 and can slide up and down are arranged in the middle of the adjusting base frame 2, and the adjusting block is fixedly connected with the annular paint spraying pipe 3.

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 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 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.
