In the specific structure, it includes the auxiliary oiling mechanism 100, a pipe seat protection mechanism 200 arranged on the auxiliary oiling mechanism 100, an outer pipe wall cleaning mechanism 300 arranged on the auxiliary oiling mechanism 100, and an oil pushing mechanism 400 arranged in the pipe seat protection mechanism 200.

[0027] The auxiliary oil filling mechanism 100 includes a first oil filling shell 110 and a second oil filling shell 120, an anti-dropping pad 170 arranged in the ports of the first oil filling shell 110 and the second oil filling shell 120, a quantitative oil control component 180 arranged in the vertical groove inside the first oil filling shell 110 and the second oil filling shell 120, and an oil delivery pipe 190 arranged on the quantitative oil control component 180, a fixing block 130 fixedly installed on the outer wall of the first oil filling shell 110, a pre-stressing bolt 150 installed in the internal screw hole of the fixing block 130, an oil scraper 140 arranged outside the threaded section of the pre-stressing bolt 150, and a propulsion component 160 arranged in the second oil filling shell 120, and the oil delivery pipe 190 is connected to an external oil pump, and the oil pump is connected to the oil storage tank through a pipeline; The propulsion assembly 160 includes a sheath 161 installed in the hole outside the second oil filling shell 120, a guide rod 162 movably installed inside the sheath 161, a first pressure block 163 installed at the inner end of the guide rod 162, and a first spring 164 arranged outside the guide rod 162; One end of the first spring 164 is pressed on the sheath 161, and the other end of the first spring 164 is pressed on the first pressure block 163; The quantitative oil control assembly 180 includes an oil tank 182 movably mounted in the vertical slot, a tension spring 184 connected to the inside of the oil tank 182, a plug 183 arranged inside the oil tank 182 and connected to the tension spring 184, a clamp 181 arranged outside the oil tank 182 and located in the vertical slot, an inclined bracket 185 movably mounted on the clamp 181 and in an inclined state, a bracket 186 movably connected to the other end of the inclined bracket 185, a tension spring 184 installed at the other end of the bracket 186, and a second spring 188 arranged outside the bracket 186 and bearing pressure on a second pressure block 187; The port of the anti-slip pad 170 is symmetrically adapted to the stainless steel pipe base 550 and the inner end of the stainless steel pipe 600. The anti-slip pad 170 is composed of an impermeable pad plate and a fan-shaped anti-overflow baffle, and the fan-shaped anti-overflow baffle is used to provide anti-seepage protection for the gap of the inner end slot of the first oil filling shell 110.

[0028] When the swing arm swings, the first oil filling shell 110 and the second oil filling shell 120 provided at the bottom of the swing arm 520 will roll over and approach the stainless steel pipe base 550 along the sliding seat 530. As the stainless steel pipe 600 is delivered along the rotation of the stainless steel pipe base 550 until its inner end is inserted into the inner cavity of the first oil filling shell 110 and the second oil filling shell 120, the anti-dropping pad 170 will first provide pressure protection for the inner end of the steel pipe; As the external oil pump draws the oil in the oil reservoir outward, the actively drawn oil will be input into the oil tank 182 through the oil delivery pipe 190, and finally the oil will push the plug 183 outward, and the oil will continue to be input into the stainless steel pipe through the inner cavity of the first oil injection shell 110 and the second oil injection shell 120 under constant pressure. At this time, the actively output oil can form a platform for cutting off the transfer of the first oil injection shell 110 and the second oil injection shell 120, and the oil can be input into the steel pipe stably and with balanced pressure; As the oil filling in the stainless steel pipe 600 is completed and the stainless steel pipe 600 is withdrawn, the moment the external oil pump stops operating, the tension spring 184 will actively stretch the plug 183 toward the inside of the oil tank 182. At this time, the plug 183 can quickly seal the port of the oil tank 182, thereby avoiding the problem of excessive oil overflowing from the oil filling hole when the stainless steel pipe 600 is drawn out.

[0029] Example 2

[0030] Combination Figure 8-Figure 14As shown, on the basis of embodiment 1, the pipe seat protection mechanism 200 includes a main outer cover 210 arranged on the first oil filling shell 110, a sub-outer cover 220 arranged on the second oil filling shell 120, four clamping seats 230 installed at the bottom of the first oil filling shell 110 and the second oil filling shell 120, a limiting rod 240 arranged in the clamping seat 230, and a third spring 250 arranged outside the limiting rod 240; The pipe seat protection mechanism 200 is used to adapt to the stainless steel pipe base 550 and provide a platform for continuous pressurization of the oil in the stainless steel pipe 600.

[0031] Preferably, the main outer cover 210 and the auxiliary outer cover 220 are fixedly mounted on the first oil filling shell 110 and the second oil filling shell 120 by bolts, wherein two clamping seats 230 are fixed to the bottom of the main outer cover 210 by bolts, and the other two clamping seats 230 are fixed to the bottom of the second oil filling shell 120 by bolts; After the combination, the ports of the main outer cover 210 and the auxiliary outer cover 220 away from the first oil filling shell 110 and the second oil filling shell 120 will form a symmetry with the end pipe in the stainless steel base after being turned over; In actual use, an anti-seepage gasket needs to be provided between the end surface of the first oil filling shell 110 and the main outer cover 210 , and between the end surface of the second oil filling shell 120 and the auxiliary outer cover 220 .

[0032] Furthermore, the oil pushing mechanism 400 includes an oil drum cover 410 and a sealing plate 420 movably installed inside the auxiliary outer cover 220, two pads 430 installed inside the oil drum cover 410 and the sealing plate 420, a linkage shaft 440 movably installed in the outer end cavity of the oil drum cover 410 and the sealing plate 420, an impeller 450 movably installed in the inner end cavity of the oil drum cover 410 and the sealing plate 420, and a chain 460 transmission-connected to the linkage shaft 440 and the impeller 450.

[0033] Among them, the oil pushing mechanism 400 is used to actively pressurize the oil input into the inner wall of the steel pipe, so as to effectively remove impurities on the inner wall of the steel pipe under the flushing of the pressurized oil, thereby avoiding the occurrence of bubbles and suspended faults on the inner wall of the steel pipe.

[0036] Example 3

[0037] Combination Figure 5-Figure 14 As shown, on the basis of Example 1, the outer tube wall cleaning mechanism 300 includes two clamps 340 arranged on the first oil filling shell 110, a shaft 350 movably installed in the bearings of the two clamps 340, a second rotating wheel 360 arranged at one end of the shaft 350, a third rotating wheel 370 arranged at the other end of the shaft 350, a facial cleaning belt 380 transmission-connected to the third rotating wheel 370 and the anti-slip pad 170, a slide seat 320 arranged on the second oil filling shell 120, a chassis 310 movably installed in the slide seat 320, and a driving assembly 330 arranged outside the chassis 310 and the second rotating wheel 360; The driving assembly 330 includes a motor 331 installed inside the chassis 310, a first rotating wheel 332 installed on a transmission shaft inside the motor 331, and a transmission belt 333 connected to the first rotating wheel 332 and the second rotating wheel 360, and a plug hole is provided at the outer end of the transmission shaft; Two auxiliary pressure wheels 334 and two pressure wheels 335 are symmetrically arranged on the outside of the transmission belt 333, and an outer frame 336 is arranged on the outside of the two auxiliary pressure wheels 334 and the two pressure wheels 335. The outer frame 336 is movably installed on the outside of the four limit rods 240, and the third spring 250 is adapted to bear pressure on the outer frame 336.

[0038] Preferably, the slide 320 is fixed to the second oil filling shell 120 by bolts. When the propulsion assembly 160 is squeezed by the stainless steel port, the propulsion assembly 160 will tend to stretch outward, and the chassis 310 body movably installed in the slide 320 will be compressed and stretch outward at a uniform speed. At this time, the outer frame 336 can slowly move toward the bottom of the first oil filling shell 110 and the second oil filling shell 120 under the elastic support of the four third springs 250, and the driving assembly 330 will also cooperate with the stretched motor 331 to adapt to the tightening and stretching in this process; After the motor 331 is started, the tautly stretched transmission belt 333 will also be driven by the first rotating wheel 332, and finally the horizontally placed shaft 350 clamped by the two clamps 340 can be driven by the second rotating wheel 360, and the facial cleaning belt 380 pressed in the annular groove of the third rotating wheel 370 can fully clean the stainless steel outer wall during rotation.

[0039] When the outer frame 336 is movably mounted on the outside of the four limit rods 240, the third spring 250 arranged on the outside of the limit rods 240 will provide a stable elastic support force for the outer frame 336. At this time, the two auxiliary pressure wheels 334 and the two pressure wheels 335 arranged in the outer frame 336 can provide an adaptive auxiliary rotation pressure platform for the transmission belt 333 to ensure that the transmission belt 333 can cooperate with the extension of the oil pushing mechanism 400 to provide constant pressure kinetic energy. The driving assembly 330 is used to provide the cleaning belt 380 with kinetic energy to indirectly remove the excess oil after impurities on the outer wall of the steel pipe; The propulsion assembly 160, which is pressurized by the steel pipe and extends outward, provides the chassis 310 with a propulsion force for extension; The raised scraper plate 140 is used to provide a medium for squeezing oil and removing impurities for the continuously rotating facial cleaning belt 380 .

[0040] The bottom of the main outer cover 210 and the auxiliary outer cover 220 are both provided with guide grooves, and the guide grooves are used to provide a limit for the transmission belt 333 after deformation and extension, and at the same time provide an unobstructed channel for the rotation of the transmission belt 333 after deformation.

[0041] According to the requirements of the cleaning belt 380 for cleaning the outer wall of stainless steel, the worker needs to loosen the pre-stressing bolt 150 in advance, and then control the relaxed scraper plate 140 to extend downward along the inner side of the fixed block 130 until the end plate on the top of the scraper plate 140 presses the bottom of the cleaning belt 380 downward. When the bottom of the cleaning belt 380 is bent and tightened, the pre-stressing bolt 150 can be tightened clockwise. At this time, the cleaning belt 380 driven at a uniform speed can apply pressure on the scraper plate 140 to effectively remove the excess oil and foreign particles adsorbed on the outer wall of the stainless steel.

[0042] The working principle and use process of the present invention: combined with Figure 1 and Figure 2 As shown, when the device needs to inject oil into the stainless steel pipe 600, as the swing arm 520 swings, the sliding seat 530 moves along the slide rail 540. The sliding seat 530 is usually driven by the oil cylinder in the prior art, so that the swing arm 520 swings along the stroke groove 510. At this time, the auxiliary oil injection mechanism 100 arranged at the bottom end of the swing arm 520 will carry the pipe seat protection mechanism 200, the outer pipe wall cleaning mechanism 300 and the oil pushing mechanism 400 to turn over toward the stainless steel pipe unit until the hole in the auxiliary oil injection mechanism 100 is docked with the stainless steel pipe 600 in the stainless steel pipe base 550.

[0043] When the above preparations are completed, the oil in the oil storage tank can be pumped out by using the oil pump and transferred to the inner cavity of the oil tank 182 through the oil pipe 190. As the oil in the inner cavity of the oil tank 182 continues to increase, the oil will eventually push the plug 183 outward until the oil flows into the inner cavity of the stainless steel pipe along the gap between the plug 183 and the oil tank 182. With the continuous output of the oil, the inner ends of the oil drum cover 410 and the sealing plate 420 will also be inserted into the cavity formed by the main outer cover 210 and the auxiliary outer cover 220. At this time, the inner ends of the oil drum cover 410 and the sealing plate 420 will seal the inner cavities of the main outer cover 210 and the auxiliary outer cover 220.

[0044] As the motor 331 is started, its internal transmission shaft will simultaneously drive the first rotating wheel 332 and the linkage shaft 440 to rotate. At this time, the first rotating wheel 332 and the linkage shaft 440 will rotate at a constant speed.

[0045] When the linkage shaft 440 is driven, the impeller 450 will also rotate in the cavity at the inner end of the oil drum cover 410 and the sealing plate 420 through the transmission of the chain 460. As the impeller 450 rotates at a high speed, the oil passing through the inner cavity of the first oil filling shell 110 and the second oil filling shell 120 can be continuously pressurized by the impeller 450 toward the inside of the stainless steel pipe. This process can increase the contact area of ​​the oil with the pipe wall to avoid the adhesion of air and other impurities to the oil to cause bubbles.

[0046] When the first rotating wheel 332 rotates, the transmission belt 333 will transmit the second rotating wheel 360 under the auxiliary pressure of the two sets of auxiliary pressure wheels 334 and the two sets of pressure wheels 335, and the shaft 350 clamped by the two clamps 340 will also be linked with the second rotating wheel 360, and finally the clamp 340 set at the other end of the second rotating wheel 360 will drive the cleaning belt 380 to rotate. Since the end of the cleaning belt 380 away from the clamp 340 is limited by the anti-slip pad 170 and penetrates into the cavity formed by the first oil filling shell 110 and the second oil filling shell 120, at the moment when the cleaning belt 380 rotates, the cleaning belt 380 can remove excess oil and foreign particles on the outer wall of the stainless steel pipe to avoid wear on the inner walls of the first oil filling shell 110, the second oil filling shell 120, the main outer cover 210 and the auxiliary outer cover 220. After the stainless steel pipe is rotated and delivered, the cleaning belt 380 can fully clean the outer wall of the pipe.

[0047] As the stainless steel pipe is continuously delivered, the end of the steel pipe inserted into the inner cavity of the first oil filling shell 110 and the second oil filling shell 120 will apply an extrusion force to the first pressure block 163 and the second pressure block 187. As the first pressure block 163 and the second pressure block 187 shrink inward, the first pressure block 163 and the guide rod 162 can push the chassis 310 outward, and the second pressure block 187 will also push the bracket 186 and the inclined frame 185 to extend outward until the clamp 181 drives the oil tank 182 to shrink into the vertical groove inside the first oil filling shell 110 and the second oil filling shell 120. At this time, the inner cavity of the first oil filling shell 110 and the second oil filling shell 120 can achieve a hollow state, thereby realizing the free outward delivery of the stainless steel pipe after oil filling.

[0048] In combination with the above, the scraper plate 140 with adjusted height will exert pressure on the bottom of the cleaning belt 380. As the cleaning belt 380 rotates, the excess oil adsorbed by the cleaning belt 380 can be squeezed out, thereby avoiding excessive oil from causing oil spill interference on the outer wall of the steel pipe, while improving the efficiency of impurity removal.

[0049] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
