Description

A metal workpiece painting device Technical Field

[0001] This invention relates to the field of lamp post painting technology, and more particularly to a metal workpiece painting device. Background Technology

[0002] Streetlight poles along city roads are generally made of steel pipes. Manufacturers have already applied anti-corrosion paint. However, since streetlight poles are erected outdoors, they are exposed to wind, rain and sun all year round. As a result, the outer surface of the streetlight poles may develop patches or large areas of paint peeling and rust. This not only affects the aesthetics of the city but also shortens the lifespan of the streetlight poles.

[0003] The diameter of a street light pole generally varies with its height. The diameter at the base of the pole is relatively large and gradually decreases as the height increases. Existing painting equipment can generally only climb and paint on poles with the same diameter and cannot be used on poles with varying diameters. Therefore, a painting equipment for metal workpieces is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes a metal workpiece painting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal workpiece painting device, comprising two wrapping mechanisms rotatably connected, with a common connecting mechanism between the two wrapping mechanisms, and a common communicating mechanism fixedly installed on the outer side of the two wrapping mechanisms. Multiple spraying mechanisms, each including a nozzle, are fixedly installed on the wrapping mechanisms and are all connected to the communicating mechanism. Multiple driving mechanisms, each equally spaced, are fixedly installed on the top of the wrapping mechanisms. These driving mechanisms can drive the two wrapping mechanisms to move up and down along the lamp post axis and rotate around the lamp post axis. During the up-and-down movement of the wrapping mechanisms along the lamp post axis, the distance between the nozzle and the lamp post remains constant.

[0006] Preferably, the packaging mechanism includes two arc-shaped plates, and multiple partitions are fixedly installed between the two arc-shaped plates at equal intervals. The same hinge block one is fixedly installed between the two arc-shaped plates on one packaging mechanism, and the same hinge block two is fixedly installed between the two arc-shaped plates on the other packaging mechanism. The hinge block one and the hinge block two are rotatably connected.

[0007] Preferably, the spraying mechanism includes two rectangular frames fixedly mounted on two arc-shaped plates, with the same hinge block slidably mounted inside the two rectangular frames. The same guide rod is fixedly mounted on the inner walls of both sides of the rectangular frames. The guide rod passes through the rectangular block and is slidably connected to the rectangular block. A spring is slidably sleeved on the guide rod. The two ends of the spring are fixedly connected to the rectangular block and the inner wall of the rectangular frame, respectively. A connecting arm is fixedly mounted on the top of the rectangular block, and a nozzle is fixedly mounted on the top of the connecting arm.

[0008] Preferably, a connecting seat is fixedly installed on the side of the rectangular block near the center of the arc plate, the connecting seat is located between the two rectangular frames, and a bullseye ball bearing is fixedly installed on the end of the connecting seat away from the rectangular block.

[0009] Preferably, the connecting mechanism includes two arc-shaped boxes fixedly installed on the outside of the two wrapping mechanisms. The arc-shaped boxes located on the outside of the wrapping mechanisms are fixedly connected to the outside of the two arc-shaped plates. A flexible tube is fixedly installed through one end of each of the two arc-shaped boxes. The ends of the two flexible tubes away from the corresponding arc-shaped boxes are fixedly connected to the same tee pipe. The spraying mechanism also includes a telescopic tube fixedly installed on the nozzle. A connecting pipe is fixedly installed at the end of the telescopic tube away from the nozzle. The connecting pipe is L-shaped, and the bottom end of the connecting pipe passes through the corresponding arc-shaped box and is fixedly connected to the arc-shaped box.

[0010] Preferably, the driving mechanism includes a mounting base fixedly installed on the top of the arc-shaped plate, the mounting base and the nozzle being located on the same side of the arc-shaped plate, an open mounting frame being fixedly installed on the top of the mounting base, a common round rod being fixedly installed between the inner walls of the two sides of the open mounting frame, a slider being slidably sleeved on the round rod, a swing arm being hinged on the mounting base, a common hinge arm being hinged between the swing arm and the slider, a mounting block being rotatably installed on the top of the swing arm, and a hub motor being rotatably installed on one side of the mounting block.

[0011] Preferably, a second spring is slidably sleeved on the round rod, and the two ends of the second spring are fixedly connected to the slider and the open mounting frame, respectively. The mounting block and the swing arm are hinged together by the same electric push rod, and the electric push rod is located on the side of the mounting block away from the hub motor.

[0012] Preferably, the connecting mechanism includes two connecting blocks, which are respectively fixedly connected to two arc-shaped plates of the corresponding wrapping mechanism, and the two connecting blocks are detachably installed with the same pin.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention enables the entire device to climb on light poles of different diameters through multiple drive mechanisms. When climbing on tapered light poles, the multiple drive mechanisms can automatically adjust to ensure that the hub motors on the multiple drive mechanisms are always in close contact with the tapered light pole.

[0015] 2. When painting the tapered light pole, the bullseye ball bearing, which is always pressed against the tapered light pole, ensures that the distance between the spray nozzle and the light pole remains constant as the entire device moves along the axis of the tapered light pole, so that the paint thickness sprayed by the spray nozzle at different heights of the tapered light pole remains consistent.

[0016] 3. By adjusting the angle of the hub motors on the drive mechanism, when the hub motors are in a vertical position, multiple hub motors can drive the entire device to move vertically up and down along the axis of the light pole. When the hub motors are in a horizontal position, multiple hub motors can drive the entire device to rotate around the axis of the light pole, allowing for painting of a local area at a certain height of the light pole. When the hub motors are in an inclined position, multiple hub motors can drive the entire device to move vertically up and down in a spiral motion along the axis of the light pole. When the device climbs to the highest point of the light pole, it can simultaneously perform spiral painting from top to bottom on the entire outer side of the light pole.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Referring to Figures 1-6, the present invention provides a technical solution: a metal workpiece painting device, comprising two wrapping mechanisms 1 rotatably connected, with a common connecting mechanism 5 between the two wrapping mechanisms 1, and a common connecting mechanism 4 fixedly installed on the outer side of the two wrapping mechanisms 1. Multiple spraying mechanisms 2, evenly spaced, are fixedly installed on the wrapping mechanisms 1, each spraying mechanism 2 including a nozzle 26. All spraying mechanisms 2 are connected to the connecting mechanism 4. Multiple driving mechanisms 3, evenly spaced, are fixedly installed on the top of the wrapping mechanisms 1. The multiple driving mechanisms 3 can drive the two wrapping mechanisms 1 to move up and down along the lamp post axis and rotate the two wrapping mechanisms 1 around the lamp post axis. During the up-and-down movement of the wrapping mechanisms 1 along the lamp post axis, the distance between the nozzle 26 and the lamp post remains constant.

[0026] The packaging mechanism 1 includes two arc-shaped plates 11, and multiple partitions 12 are fixedly installed between the two arc-shaped plates 11 at equal intervals. The same hinge block 13 is fixedly installed between the two arc-shaped plates 11 on one packaging mechanism 1, and the same hinge block 24 is fixedly installed between the two arc-shaped plates 11 on the other packaging mechanism 1. The hinge block 13 and the hinge block 214 are rotatably connected.

[0027] The spraying mechanism 2 includes two rectangular frames 21 that are fixedly installed on two arc-shaped plates 11 respectively. The same hinge block 14 is slidably installed inside the two rectangular frames 21. The same guide rod 22 is fixedly installed on the inner walls of both sides of the rectangular frames 21. The guide rod 22 passes through the rectangular block 24 and is slidably connected to the rectangular block 24. A spring 23 is slidably sleeved on the guide rod 22. The two ends of the spring 23 are fixedly connected to the rectangular block 24 and the inner wall of the rectangular frame 21 respectively. A connecting arm 25 is fixedly installed on the top of the rectangular block 24. A nozzle 26 is fixedly installed on the top of the connecting arm 25.

[0028] A connecting seat 29 is fixedly installed on the side of the rectangular block 24 near the center of the arc plate 11. The connecting seat 29 is located between the two rectangular frames 21. A bullseye ball bearing 210 is fixedly installed on the end of the connecting seat 29 away from the rectangular block 24.

[0029] The connecting mechanism 4 includes two arc-shaped boxes 41 fixedly installed on the outside of the two wrapping mechanisms 1. The arc-shaped boxes 41 located on the outside of the wrapping mechanism 1 are fixedly connected to the outside of the two arc-shaped plates 11. One end of each arc-shaped box 41 is fixedly installed with a flexible tube 42. The end of the two flexible tubes 42 away from the corresponding arc-shaped box 41 is fixedly connected to the same tee pipe 43. The spraying mechanism 2 also includes a telescopic tube 28 fixedly installed on the nozzle 26. The end of the telescopic tube 28 away from the nozzle 26 is fixedly installed with a connecting pipe 27. The connecting pipe 27 is L-shaped, and the bottom end of the connecting pipe 27 passes through the corresponding arc-shaped box 41 and is fixedly connected to the arc-shaped box 41.

[0030] Furthermore, when the rectangular block 24 moves within the two rectangular frames 21, the distance between the nozzle 26 and the connecting pipe 27 will automatically change, and the telescopic pipe 28 will extend or retract accordingly, thereby ensuring that the connecting pipe 27 and the nozzle 26 are always connected through the telescopic pipe 28.

[0031] The drive mechanism 3 includes a mounting base 31 fixedly mounted on the top of the arc plate 11. The mounting base 31 and the nozzle 26 are located on the same side of the arc plate 11. An open mounting frame 32 is fixedly mounted on the top of the mounting base 31. The same round rod 33 is fixedly mounted between the inner walls of the two sides of the open mounting frame 32. A slider 34 is slidably sleeved on the round rod 33. A swing arm 36 is hinged on the mounting base 31. The same hinge arm 37 is hinged between the swing arm 36 and the slider 34. A mounting block 38 is rotatably mounted on the top of the swing arm 36. A hub motor 39 is rotatably mounted on one side of the mounting block 38.

[0032] A second spring 35 is slidably sleeved on the round rod 33. The two ends of the second spring 35 are fixedly connected to the slider 34 and the open mounting frame 32, respectively. The same electric push rod 310 is hinged between the mounting block 38 and the swing arm 36. The electric push rod 310 is located on the side of the mounting block 38 away from the hub motor 39.

[0033] The connecting mechanism 5 includes two connecting blocks 51, which are fixedly connected to the two arc-shaped plates 11 of the corresponding wrapping mechanism 1, and the same pin 52 is detachably installed between the two connecting blocks 51.

[0034] Furthermore, when the two connecting blocks 51 are fixedly connected by the pin 52, the two wrapping mechanisms 1 will be in a coaxial state.

[0035] In this embodiment: When in use, first pull the pin 52 out from between the two connecting blocks 51, then rotate the two wrapping mechanisms 1 to increase the distance between the two connecting blocks 51, then put the two wrapping mechanisms 1 from the opening of the two connecting blocks 51 onto the lowest point of the lamp post, then rotate the two wrapping mechanisms 1 again and insert the pin 52 into the two connecting blocks 51. At this time, under the action of multiple hub motors 39 abutting against the outside of the lamp post, the two wrapping mechanisms 1 are coaxially set with the lamp post, and at the same time, the bullseye balls 210 on each spraying mechanism 2 also abut against the outside of the lamp post. At this time, the two springs 23 on the spraying mechanism 2 and the spring 35 on the drive mechanism 3 are all in a stretched state.

[0036] Then, the hub motors 39 on the multiple drive mechanisms 3 are controlled to rotate simultaneously. Under the rotation drive of the multiple hub motors 39 against the outside of the lamp post, the two wrapping mechanisms 1 can be moved upward simultaneously. Since the lamp post is truncated cone-shaped, when the hub motors 39 drive the entire drive mechanism 3 to move upward, it will gradually move from the thicker part of the lamp post to the thinner part. The stretched spring 35 on the drive mechanism 3 will gradually reset and shorten. During the shortening process of the spring 35, the slider 34 will move downward and drive the swing arm 36 to rotate around the mounting base 31 through the hinge arm 37. The swing arm 36 then drives the hub motors 39 away from the open mounting frame 32 through the mounting block 38 and always sticks to the outside of the lamp post. At this time, the air supply pipe for pumping paint is connected to the three-way pipe 43.

[0037] During the upward movement of the wrapping mechanism 1 driven by multiple drive mechanisms 3, the bullseye ball 210 on the outside of the lamp post on the spraying mechanism 2 will closely adhere to the outside of the lamp post and gradually move upward. As the spraying mechanism 2 moves from the thicker part at the bottom of the lamp post to the thinner part at the top, the bullseye ball 210 continuously moves towards the axis of the lamp post. Under the restoring force of the two stretched springs 23 on the spraying mechanism 2, not only can the bullseye ball 210 always adhere to the outside of the lamp post, but also, during the movement of the bullseye ball 210 towards the axis of the lamp post, it will pull the rectangular block 24 along with the bullseye ball 210 towards the axis of the lamp post through the connecting seat 29. The rectangular block 24 then drives the nozzle 26 towards the axis of the lamp post through the connecting arm 25. Therefore, during the up and down movement of the wrapping mechanism 1, no matter what height position the spraying mechanism 2 is at on the lamp post, the position of the nozzle 26 from the outside of the lamp post remains unchanged.

[0038] When multiple spraying mechanisms 2 reach the height of the lamp post to be painted, the electric push rods 310 on the multiple spraying mechanisms 2 are simultaneously shortened. During the shortening process, the electric push rods 310 will drive the mounting block 38 to rotate 90 degrees around the electric push rods 310. At this time, the circular vertical hub motor 39 will change to a horizontal state. When the multiple hub motors 39 are rotating, they can drive the entire device to rotate around the axis of the lamp post. At this time, the paint in the arc-shaped box 41 is sprayed out from the corresponding swing arm 36 through the various connecting pipes 27 and telescopic pipes 28 and acts on the outside of the lamp post. At this time, the multiple nozzles 26 can perform painting operations on a certain area of ​​the lamp post.

[0039] When painting the entire outer side of the lamp post, the control device first climbs to the highest point of the lamp post. Then, by controlling the shortening length of the electric push rod 310, the angle of the mounting block 38 is between 0 and 90 degrees. At this time, the hub motors 39 on the multiple drive mechanisms 3 are in an inclined state, and the rotation direction of the hub motors 39 is adjusted. Then, under the rotation of the multiple hub motors 39, the entire device can be spiraled downward around the axis of the lamp post, so that the multiple spray nozzles 26 can evenly spray the entire outer side of the lamp post from top to bottom.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
