Description

Technical Field

[0001] The present invention relates to the technical field of I-beam spraying processing, and in particular, to an I-beam arch spraying device and a spraying method. Background Art

[0002] An I-beam is a metal profile with an "I"-shaped cross-section, which plays a crucial role in industrial development and has a wide range of applications. In many construction projects, due to its special structure, the I-beam has multiple surfaces. For example, the side surface has three surfaces. When spraying and processing it, the processing of the side surface is relatively cumbersome. At present, the general spraying equipment moves and sprays along the length direction of the profile, with relatively low efficiency and the need for movement control. Moreover, when spraying the "匚"-shaped side surface of the I-beam, the I-beam cannot be continuously sprayed, which easily causes the spraying of some surfaces to overlap each other when spraying the "匚"-shaped side surface of the I-beam, resulting in poor spraying effects on each surface of the I-beam. Based on this, the present invention proposes a spraying device that can efficiently complete the spraying and processing of each surface of the I-beam profile. Summary of the Invention

[0036] Embodiment

[0037] The present invention provides an I-beam arch spraying device, as Figure 1-Figure 7 shown, which includes a base 1. The base 1 is a frame structure formed by welding steel plates. A sliding seat 34 is installed on the base 1. A first mounting frame 4 is fixed on the side wall of the sliding seat 34 by bolts. And the first mounting frame 4 is formed by opening a notch in its body through a steel structure of a whole ring, so that the first mounting frame 4 is in the shape of a superior arc. A limiting groove 10 is opened on one side of the first mounting frame 4, so that the cross section of the first mounting frame 4 is in the shape of a "C". A sliding frame 5 adapted to it is installed in the limiting groove 10. The sliding frame 5 is formed by opening a notch in its body through a steel structure of a whole ring, so that the sliding frame 5 is in the shape of a superior arc. Through the above structure, it is convenient to place the I-beam 3 in the annular spraying area formed by the above structure. There are two support frames 2 on the base 1. The support frames 2 are in the shape of an L. The support frames 2 are fixed on both sides of the base 1 by welding. The two support frames 2 are used to support the I-beam 3 in an arc shape or the I-beam 3 in a straight line shape, so that the I-beam 3 is in a suspended state, which is convenient for the spraying mechanism to spray the outer surface of the I-beam 3 without being blocked by other objects during the spraying operation. A first driving mechanism for driving the sliding seat 34 to move along the extending direction of the I-beam is provided on the base 1. The first driving mechanism can drive the spraying mechanism installed on the sliding frame 5 to move along the extending direction of the I-beam. A mounting seat 12 is installed on the side wall of the sliding frame 5 by bolts. A spraying mechanism for spraying the I-beam is provided on the mounting seat 12. A second driving mechanism for driving the sliding frame 5 to reciprocate in the limiting groove 10 is provided on the first mounting frame 4. The second driving mechanism is used to drive the sliding frame 5 to adjust the relative position between the spraying mechanism and the I-beam.

[0038] During the spraying process of the I-beam 3, first, the second driving mechanism is used to drive the sliding frame 5 to perform a circular motion in the limiting groove 10, so that the spraying end of the spraying mechanism is in a relatively parallel state with the surface to be sprayed of the I-beam. Subsequently, the first driving mechanism is started to make the spraying mechanism installed on the sliding seat 34 through the first mounting frame 4 and the sliding frame 5 move along the extending direction of the I-beam, and then the surface of the I-beam can be sprayed.

[0039] In some technical solutions of the present invention, a guide bar 9 integrally formed therewith is provided in the limiting groove 10, the cross section of the guide bar 9 is wedge-shaped, a limiting groove adapted to the guide bar 9 is provided on the side wall of the sliding frame 5, the cross section of the limiting groove is also wedge-shaped, and a part of the guide bar 9 is embedded in the limiting groove. The above structure is used to guide the sliding frame 5 to move in the limiting groove 10 along the circumferential direction of the circle where the first mounting frame 4 is located, and prevent the sliding frame 5 from falling off from the limiting groove.

[0040] Preferably, the I-beam to be sprayed is an I-beam in an arc-shaped state or an I-beam extending along a straight line.

[0041] In some technical schemes of the present invention, the first driving mechanism includes a guide member 11 installed in the support frame 2, and the guide member 11 is an I-beam, which is an I-beam in an arc state or an I-beam extending along a straight line. When the staff sprays I-beams of different shapes, the guide member 11 of the corresponding shape can be replaced to improve the adaptability of the above structure.

[0042] A guide groove adapted to the guide member 11 is provided on the side wall of the sliding seat 34, and the cross section of the guide groove is rectangular. Limiting wheels 18 are installed on the two opposite inner walls of the guide groove through brackets, and the limiting wheels 18 are rotatably arranged in the bracket through a shaft rod. A driving wheel 19 is installed on the bottom of the guide groove through a bracket, and the driving wheel 19 is rotatably arranged in the bracket through a shaft rod. A part of the driving wheel 19 is embedded in the groove of the guide member 11, and a second driving motor connected to the driving wheel 19 is installed in the sliding seat 34. The second driving motor is built into the sliding seat 34, and the second driving motor is connected to the driving wheel 19 through a belt drive, so as to drive the sliding seat 34 slidably arranged on the guide member 11, so that it moves along the extension direction of the guide member 11, and continuously sprays the same surface of the I-beam.

[0043] In some technical solutions of the present invention, the second driving mechanism includes a second mounting frame 7 fixed to the sliding seat 34 by bolts, a first driving motor 6 is installed on the side wall of the second mounting frame 7 by bolts, and a driving wheel 14 is installed on the output end of the first driving motor 6, and the driving wheel 14 is a gear structure. A through hole is opened on the outer wall of the first mounting frame 4, the through hole is connected to the limit groove 10, and a part of the sliding frame 5 is exposed at the through hole, and two driven wheels 15 are arranged in the through hole through the rotation of the pin shaft, and the driven wheels 15 are gear structures. A transmission belt 8 is sleeved between the driving wheel 14 and the two driven wheels 15. The transmission belt 8 is a flexible toothed belt structure. The outer wall of the transmission belt 8 abuts against the outer wall of the sliding frame 5. When the transmission belt 8 and the sliding frame 5 are in contact, the friction between the two is relatively large. In this way, under the drive of the second driving mechanism, the sliding frame 5 can make continuous circular motion in the limiting groove 10, and stop at a certain position in the limiting groove 10 under the restriction of the transmission belt 8, ensuring that the spraying mechanism stays at the specified position, thereby improving the spraying effect of this structure on the I-beam.

[0044] Preferably, in order to ensure that the sliding frame 5 does not slide relative to each other when driven by the transmission belt 8, a toothed belt is provided on the outer circumferential wall of the sliding frame 5, and the transmission belt 8 is provided with a tooth block that engages with the toothed belt to improve the meshing ability of the two, and the transmission belt 8 is used to achieve a partial self-locking function for the sliding frame 5 to prevent the sliding frame 5 from rotating freely.

[0045] In some technical schemes of the present invention, the spraying mechanism includes a mounting shell 13 mounted on a mounting seat 12 by bolts, and the mounting shell 13 has a rectangular cross-section. Two first nozzle components 16 are mounted on the side of the mounting shell 13 away from the mounting seat 12 by welding, and the cross-section of the first nozzle component 16 is rectangular. A second nozzle component 17 is slidably arranged between the two first nozzle components 16, and the cross-section of the second nozzle component 17 is rectangular. A plurality of first nozzles 20 are mounted on the side wall of the first nozzle component 16 away from the mounting shell 13, and a first chamber 36 connected to the first nozzle 20 is opened in the first nozzle component 16. A plurality of second nozzles 22 are mounted on the side wall of the second nozzle component 17 away from the mounting shell 13, and a second chamber 38 connected to the second nozzle 22 is opened in the second nozzle component 17. A liquid guide channel 21 is provided on the side wall of the second nozzle member 17 opposite to the first nozzle member 16, and the liquid guide channel 21 is connected to the second chamber 38. A liquid inlet channel 37 is provided on the side wall of the first nozzle member 16 opposite to the second nozzle member 17, and the liquid inlet channel 37 is connected to the first chamber 36. A liquid conveying mechanism connected to the liquid inlet channel 37 is provided in the liquid guide channel 21. A driving structure for driving the second nozzle member 17 to reciprocate between the two first nozzle members 16 is provided in the mounting shell 13, and a conveying pipeline 35 connected to the second chamber 38 is provided in the mounting shell 13. The conveying pipeline 35 is connected to an external booster pump, and the input end of the booster pump is connected to a paint storage device. An extraction pump is also provided between the booster pump and the storage device.

[0046] In some technical solutions of the present invention, the pushing structure is a push rod 23 installed in the installation housing 13. The push rod 23 is an electric push rod, and the telescopic end of the push rod 23 is detachably connected to the side wall of the second spray head member 17 by bolts.

[0047] In some technical solutions of the present invention, grooves are formed on the opposite side walls of the two first spray head members 16. The cross-section of the groove is wedge-shaped, and a part of the second spray head member 17 is embedded in the groove. Wedge-shaped portions adapted to the grooves are machined on both sides of the second spray head member 17.

[0048] In some technical solutions of the present invention, the liquid delivery mechanism includes a communication pipe 24 installed in the liquid guide channel 21. The communication pipe 24 is embedded in the liquid guide channel 21, and a sealing ring is installed between the two to improve their sealing ability. A first pipe fitting 25 is installed in the communication pipe 24. A plugging block 30 in the shape of a frustum is slidably arranged in the first pipe fitting 25. An inner conical surface adapted to the plugging block 30 is provided at the output port of the first pipe fitting 25. A second spring is installed in the first pipe fitting 25 and is connected to the large-diameter end of the plugging block 30. One end of the second spring 29 is fixed on the inner wall of the first pipe fitting 25. A limiting rod 31 against which the small-diameter end of the plugging block 30 abuts is installed in the liquid inlet channel. A through hole 32 is formed in the plugging block 30.

[0049] In some technical solutions of the present invention, the first pipe fitting 25 is slidably arranged in the communication pipe 24. An installation block 26 is installed in the communication pipe 24 by welding. The cross-section of the installation block 26 is circular. A plurality of arc-shaped guide plates 28 are installed on the end surface of the installation block 26. The number of the guide plates 28 is 3. After the 3 guide plates 28 are welded on the end surface of the installation block 26, they enclose a circular ring structure. A part of the guide plates 28 is embedded in the first pipe fitting 25. In this way, the plurality of guide plates 28 can guide the first pipe fitting 25 to reciprocate in the communication pipe 24. A gap is reserved between any two adjacent guide plates 28. A first spring 27 abutting against the first pipe fitting 25 is sleeved on the installation block 26.

[0050] When the second spray head member 17 retracts between the two first spray head members 16 and the first pipe fitting 25 in the liquid delivery mechanism is in a misaligned state with the liquid inlet channel 37, the first spray head member 16 will squeeze the first pipe fitting 25 in the communication pipe 24 and the first spring 27. After the first pipe fitting 25 completely covers the gap reserved between any two adjacent guide plates 28, the first pipe fitting 25 will close the delivery pipeline 35 to prevent subsequent paint from continuing to be discharged.

[0051] Through the above structure, the spraying mode of the spraying mechanism can be changed from a spraying structure adapted to a single horizontal plane to a spraying structure adapted to a special-shaped surface, that is, spraying the special-shaped surface in the shape of a "匚" on both sides of the I-beam.

[0052] The first working mode of the spraying mechanism is as follows: when the second spraying member 17 is completely placed between the two first spraying members 16, the first spray head 20 on the first spraying member 16 and the second spray head 22 on the second spraying member 17 are on the same horizontal plane; at this time, the first pipe fitting 25 in the liquid delivery mechanism is embedded in the liquid inlet channel 37, and the limiting rod 31 in the liquid inlet channel 37 will push the plugging block 30 to move in the first pipe fitting 25 to compress the second spring 29; at this time, the liquid discharge channel 33 formed between the plugging block 30 and the first pipe fitting 25 will be opened, facilitating a large amount of spraying liquid entering the second chamber 38 from the delivery pipe 35 to enter the first chamber 36 through the liquid inlet channel 37, and then being ejected from the first spray head 20 on the first spraying member 16; moreover, the spraying liquid is also ejected from the second spray head 22 under the action of pressure, so as to perform spraying operations on the non - special - shaped surface of the I - beam through the above - mentioned structure.

[0053] The second working mode of the spraying mechanism is as follows: when the second spraying member 17 moves between the two first spraying members 16 under the movement of the push rod 23, the second spraying member 17 and the two first spraying members 16 form a structure in the shape of a Chinese character "pin", at this time, a part of the second spraying member 17 will be placed in the "匚"-shaped area on both sides of the I - beam. At this time, the liquid delivery mechanism will gradually move out of the restricted area between the two first spraying members 16 along with the second spraying member 17. The plugging block 30 in the liquid delivery mechanism is no longer squeezed by the limiting rod 31. The plugging block 30 will block the output end of the first pipe fitting 25 under the push of the second spring 29, and the liquid discharge channel 33 is closed. At this time, the through - hole 32 opened on the plugging block 30 communicates with the outside, and the spraying liquid is ejected from the second spray head 22 and the through - hole 32 under the action of pressure, so as to perform spraying operations on the special - shaped surface of the I - beam through the above - mentioned structure, improving the adaptation range of this structure.

[0054] Preferably, a part of the limiting rod 31 can be embedded in the through - hole 32 and abuts against the inner flange in the through - hole 32.

[0057] Subsequently, the second driving mechanism drives the sliding frame 5 to perform a circular motion in the limiting groove 10, so that the spraying end of the spraying mechanism and the surface to be sprayed of the I - beam are in a relatively parallel state;

[0058] Again, start the first driving mechanism to make the spraying mechanism move along the extending direction of the I - beam and start the spraying operation;

[0059] The first working mode of the spraying mechanism: First, the second nozzle member 17 is completely placed between the two first nozzle members 16, and the first nozzle 20 and the second nozzle 22 are on the same horizontal plane;

[0060] Second, the first pipe fitting 25 in the liquid delivery mechanism is inserted into the liquid inlet channel 37, and the limiting rod 31 pushes the plugging block 30 to compress the second spring 29;

[0061] Finally, the spraying liquid enters the second chamber 38 from the delivery pipe 35, enters the first chamber 36 through the liquid inlet channel 37, and then is ejected from the first nozzle 20 and the second nozzle 22 to spray the non - special - shaped surface of the I - beam;

[0062] The second working mode of the spraying mechanism: First, under the action of the push rod 23, the second nozzle member 17 moves out between the two first nozzle members 16 to form a "pin" - shaped structure, and a part of the second nozzle member 17 is placed in the "匚" - shaped area on both sides of the I - beam;

[0063] Second, the liquid delivery mechanism moves out of the restricted area between the two first nozzle members 16 along with the second nozzle member 17, and the plugging block 30 is no longer extruded by the limiting rod 31;

[0064] Finally, the plugging block 30 plugs the output end of the first pipe fitting 25 under the push of the second spring 29, the liquid discharge channel 33 is closed, and the spraying liquid is ejected from the second nozzle 22 and the through - hole 32 to spray the special - shaped surface of the I - beam;

[0065] After spraying is completed, the I - beam is moved out of the spraying area.
