Background
At present, after a metal slender pipeline is machined, the inner wall of the pipeline is generally required to be painted in order to prevent the interior of the pipeline from rusting; the mode of painting the inner wall of the pipeline is mainly divided into two main types, one is paint spraying, and the other is brush coating; paint is sprayed, so that paint is saved, and the paint surface is uniform; however, the required equipment is complex, and the aerosol is easy to inhale into the respiratory tract to affect the health of human bodies. Brushing, non-uniform, inefficient, but relatively low contamination.
Most of the two types of pipelines aim at thicker pipelines, and the spray head or the brush can be placed in the pipeline for construction; however, it is not suitable for some long and thin pipelines. For a long and thin pipeline, a paint self-flowing mode is generally adopted, namely, the pipeline is kept inclined, paint is poured into the pipeline from the high end, and paint flows out from the low end; this kind of mode is extravagant paint extremely to paint viscosity is big, and mobility is not good, and after the shaping, the inner wall can form great dripping and hang the trace. Meanwhile, when the paint is applied to pipelines with special-shaped cross sections, the paint cannot be conveniently and fully brushed even if a paint self-flowing mode is adopted.

the drawing part 3 comprises a fixed upright rod 301, a sleeve 305 is fixed at the upper end of the upright rod 301, the sleeve 305 can rotate, a limit pin 306 for preventing the sleeve 305 from rotating is installed on the upright rod 301, a cross rod 302 capable of moving left and right is installed in the sleeve 305, a vertical guide plate 307 is installed at the left end of the cross rod 302, a clamping block 303 capable of moving up and down along the guide plate 307 is installed on the guide plate 307, and the thin round rod 104 can be installed in the clamping block 303; a hand wheel 304 is mounted to the right end of the cross bar 302.
In order to realize that the cloth strips 103 fully adsorb the paint, the cloth strips 103 adopt flannelette strips 103, the middle of the paint box 101 is low, two sides of the paint box 101 are high, an elastic brush 109 is fixed in the middle of the bottom of the paint box 101, and bristles of the brush 109 are in contact with the cloth strips 103.
In order to realize the sliding and resetting of the sliding block 106, a spring 110 is sleeved on the fixed rod 105.
In order to facilitate the hinging of the ring 202 and the upper end of the supporting rod 201, the lower end of the ring 202 is provided with a connecting block 205, the connecting block 205 is hinged to the upper end of the supporting rod 201, a positioning hole is formed in the connecting block 205, the upper end of the supporting rod 201 is provided with a positioning rod 206, and when the positioning rod 206 is arranged in the positioning hole, the sleeve 203 is in a horizontal state.
In order to realize the clamping of the section bar; an arc-shaped plate 207 is rotatably connected inside the screw 204; a plurality of screws 204 are mounted to both left and right ends of the sleeve 203.
In order to conveniently clamp the sleeve 305, a positioning groove is formed in the outer surface of the sleeve 203, a tension spring is sleeved on the limiting pin 306, and the lower end of the limiting pin 306 can be arranged in the positioning groove.
In order to fix the thin round rod 104, the clamping block 303 is composed of three vertical plates on the upper side, the lower side and the right side, wherein the vertical plates on the upper side and the lower side are provided with long round holes; the thin round bar 104 can be blocked by the upper round holes of the upper side and the lower side; the right vertical plate can be clamped on the guide plate 307 and moves upwards along the guide plate 307, and a second compression screw 308 is arranged on the right vertical plate.
When the invention is used, firstly, the section bar is inserted into the sleeve 203, and is fixed by the section bar through the plurality of screw rods 204 on the sleeve 203; by rotating the plurality of screws 204, the arc-shaped plates 207 at the inner sections of the screws 204 can compress the profiles; because the mode of adopting a plurality of screws 204 is fixed, the profile with different sizes and different cross sections can be adapted.
Before the use, cloth strip 103 is mostly wound on reel 102, paint is added in paint box 101, paint can be adsorbed on cloth strip 103, and cloth strip 103 can adopt flannel cloth strip 103 or cotton cloth strip 103, utilizes its loose inner structure, adsorbs more paint. Then, referring to fig. 1, the section bar is obliquely arranged, so that the left end of the section bar is high and the right end of the section bar is low, and then the thin round rod 104 at the free end of the cloth strip 103 is arranged inside the section bar; and the reel 102 is reversed so that the cloth strip 103 is guided by the thin round bar 104 through the whole profile and out the other end of the profile.
After the thin round rod 104 comes out from the right end of the profile, the thin round rod 104 is installed on the clamping block 303; and the profile is restored to the horizontal state, see fig. 2; the positioning rod 206 at the upper end of the supporting rod 201 is inserted into a positioning hole on a connecting block 205 hinged with the positioning rod 206, so that the section bar is kept in a horizontal state. In this state, the profile is in the low position; a part of redundant cloth strips 103 are retracted through the forward transmission of the reel 102, and the cloth strips 103 are in a tensioned state; and the stretched state of the cloth strip 103 is maintained by screwing the first compression screw 108 on the slider 106.
Because the cloth strip 103 is in a tensioning state, the cloth strip 103 arranged in the section bar can be tightly attached to the upper side wall of the section bar in the tensioning state, at the moment, the cloth strip 103 can move left and right relative to the section bar by pulling the hand wheel 304 left and right, and when the cloth strip 103 moves left and right, the sliding block 106 can slide left and right along the fixing rod 105. By moving left and right, the paint brush on the cloth strip 103 can be painted on the inner wall of the pipeline.
Subsequently, the second compression screw 308 is loosened, and the clamping block 303 is moved to the middle position of the guide plate 307, at which time the rope is in a loose state; then, the limiting pin 306 is pulled upwards, so that the sleeve 305 can rotate, namely the cross rod 302 can rotate, and at the moment, the hand wheel 304 is rotated, so that the cloth strip 103 can be twisted for a certain number of turns; by twisting, the paint adsorbed inside the cloth strip 103 can be squeezed out.
At the same time, the sleeve 203 can be manually rotated to bring the non-coated area of the profile above, since the cloth strip 103 is in a loose state.
Then the clamping block 303 is moved to one end of the guide plate 307 again, and the limiting pin 306 is released, so that the sleeve 305 is clamped again; the cloth strip 103 can now be pulled out to the left and right to apply a new area of the profile.
By manually twisting the cloth strip 103, the paint inside can be squeezed out, so that the problem of paint thinning in subsequent areas can be avoided. The smearing is more uniform.
In the above way, the cloth strip 103 is used as an application tool, so that the cloth strip 103 can penetrate through various elongated pipelines and can be applied by selecting the cloth strip 103 with a proper length according to the length of the pipeline; in addition, for the pipeline with a non-circular cross section, particularly the pipeline with the groove on the inner wall, the cloth strips 103 can be perfectly placed in the groove to fully coat the groove; the effect that other modes are not easy to achieve can be achieved. And as long as the cloth strip 103 can be arranged on the inner wall of the pipeline, the coating of each special part of the profile can be realized through various rotations and pulls even if the shape of the profile is special.
The above is a conventional usage, and in addition to this, the present device can be used as follows: keeping the profile horizontal and the cloth strip 103 tensioned, i.e. in the state shown in figure 2; through manual rotation section bar, can utilize cloth strip 103 to carry out annular to paint to the inner wall, make paint on the inner wall more even, avoid the condition of wall built-up. The mode is more suitable for the section bar with the regular cross section, and the smearing efficiency and the smearing uniformity can be improved.
