Description

Technical Field

[0001] This utility model relates to the field of paint mist treatment technology, specifically a foldable universal air collection arm. Background Technology

[0002] In the shipbuilding industry, painting operations generate a large amount of paint mist pollutants, which need to be collected in a timely manner by gas collection equipment to protect the environment and workers' health. Existing gas collection devices are mostly fixed or simple lifting types, such as fixed bracket gas collection hoods or single-section telescopic arms, which can only cover a limited height (usually <5 meters) and angle. They cannot meet the dynamic collection needs of 10-14 meters high working height in ship superstructures. When the spray gun working surface moves with the lifting frame, the fixed gas collection hood is difficult to adjust synchronously, causing a large amount of paint mist to diffuse outside the working area. At the same time, conventional gas collection hoods are mostly flat-topped or have small openings, such as circular flat hood openings, which are insufficient in capturing the sloping diffused paint mist generated by high-altitude spraying, thus significantly aggravating the leakage phenomenon.

[0003] Therefore, there is an urgent need for a foldable universal air-gathering arm to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a foldable universal air collection arm, including a universal arm and a collection component disposed on the universal arm for collecting paint mist generated during ship painting operations;

[0005] The collection assembly includes a collection cover fixedly connected to the operating end of the universal arm. The collection cover is rectangular and has connection slots on four side walls away from the universal arm. The four connection slots are connected to flow guide plates via rotating shafts. The collection cover is provided with a drive assembly for driving the four flow guide plates and a return assembly for returning the four flow guide plates.

[0006] The end of the collection hood furthest from the four diversion plates is fixedly connected to an air extraction pipe. The end of the air extraction pipe furthest from the collection hood is connected to an air supply pipe via a flexible steel wire hose. The end of the air supply pipe furthest from the air extraction pipe is connected to an external high-pressure air pump.

[0007] The gas pipeline is laid along the mechanical arm of the universal arm and is limited by a snap-fit ​​device.

[0008] The drive assembly includes two symmetrically arranged first fixing plates fixedly connected to the side wall of the collection hood. A drive rod is rotatably connected between the two first fixing plates. Multiple winding reels are fixedly connected to the side wall of the drive rod. Each winding reel is wound with a pull rope. Multiple lifting rings are threadedly connected to the side of the diversion plate near the drive rod. The end of each pull rope away from the winding reel is connected to each lifting ring. One of the two first fixing plates is equipped with a motor. The output end of the motor is connected to the drive rod.

[0009] The collecting cover is fixedly connected to two symmetrically arranged second fixed plates on the side near the first fixed plate. A rotating roller is rotatably connected between the two second fixed plates, and each of the pull ropes is slidably connected to the rotating roller.

[0010] The return assembly includes a return plate disposed on one side of the collection cover. One end of the rotating shaft passes through the collection cover and is connected to the return plate. A torsion spring is sleeved on the side wall of the rotating shaft, and the two ends of the torsion spring are respectively connected to the return plate and the side wall of the collection cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model's foldable universal air collection arm, through the setting of the collection components and the extension and swing of the universal arm, can adapt to pollution sources at different heights and positions, thereby effectively collecting paint mist generated at different locations.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figures 1-3 The figure shows a foldable universal air collection arm, which includes a universal arm 1 and a collection component disposed on the universal arm 1 for collecting paint mist generated during ship painting operations.

[0020] The collection assembly includes a collection cover 201 fixedly connected to the operating end of the universal arm 1. The collection cover 201 is rectangular and has connection slots 202 on four side walls away from the universal arm 1. The four connection slots 202 are connected to the diversion plates 204 through the rotating shaft 203. The collection cover 201 is provided with a drive assembly for driving the four diversion plates 204 and a return assembly for returning the four diversion plates 204.

[0021] It should be noted that by setting up the collection components and utilizing the extension and swing of the universal arm 1, it can adapt to pollution sources at different heights and positions, thereby effectively collecting paint mist generated at different locations. Compared with fixed-position gas collection equipment, it has a wider coverage range and stronger practicality. Furthermore, with the cooperation of the drive component and the return component, by adjusting the angle of the guide plate 204, a "directional negative pressure zone" is formed, which facilitates the guidance of paint mist to converge towards the air inlet, thereby improving the capture capability of diffused paint mist and reducing the risk of paint mist leakage.

[0022] It is worth noting that the universal arm 1 is based on the linkage mechanism principle, and achieves multi-directional rotation through the coordinated movement of each joint. Each joint has a specific axis of rotation. When multiple joints rotate at different angles, the end effector of the universal arm 1 can reach different positions and directions in space. The operator can manually or through the control system adjust the angle of the joints to achieve precise control of the position and attitude of the end effector. This application only provides a simple illustration and does not accurately represent the specific structure of the existing universal arm 1. Moreover, as the prior art, the specific structure and working principle of the universal arm 1 have been mastered by those in the art, and will not be described in detail here.

[0023] Please see Figure 2 and Figure 3In the diagram, the end of the collection hood 201 away from the four diversion plates 204 is fixedly connected to the suction pipe 205. The end of the suction pipe 205 away from the collection hood 201 is connected to the gas supply pipe 207 through the steel wire hose 206. The end of the gas supply pipe 207 away from the suction pipe 205 is connected to an external high-pressure suction pump.

[0024] It should be noted that the steel wire hose 206 provides operational space for changing the position of the collection cover 201.

[0025] Please see Figure 2 and Figure 3 The gas pipe 207 shown in the figure is laid along the mechanical arm of the universal arm 1 and is limited by the snap-fit ​​component;

[0026] It should be noted that by laying the gas pipe 207 along the mechanical arm of the universal arm 1 and limiting it with a snap fastener, the risk of the gas pipe 207 becoming tangled or knotted can be reduced.

[0027] Please see Figure 2 and Figure 3 The driving assembly shown in the figure includes two symmetrically arranged first fixing plates 301 fixedly connected to the side wall of the collection cover 201. A driving rod 302 is rotatably connected between the two first fixing plates 301. Multiple winding reels 303 are fixedly connected to the side wall of the driving rod 302. Each winding reel 303 is wound with a pull rope 304. Multiple lifting rings 305 are threadedly connected to the side of the diversion plate 204 near the driving rod 302. The end of each pull rope 304 away from the winding reel 303 is connected to each lifting ring 305. One of the two first fixing plates 301 is equipped with a motor 306. The output end of the motor 306 is connected to the driving rod 302.

[0028] It should be noted here that the drive component is designed to facilitate the rotation of the diversion plate 204, thereby enabling the adjustment of the angle of the diversion plate 204.

[0029] Please see Figure 2 and Figure 3 In the figure, the collection cover 201 is fixedly connected to two symmetrically arranged second fixed plates 308 on the side near the first fixed plate 301. A rotating roller 307 is rotatably connected between the two second fixed plates 308, and each pull rope 304 is slidably connected to the rotating roller 307.

[0030] It should be noted here that the rotating roller 307 is used to guide and limit the movement of the pull rope 304.

[0031] Working principle: When collecting paint mist generated during ship painting operations, the collection hood 201, driven by the universal arm 1, can accurately follow the working surface of the spray gun on the top of the lifting frame by extending and swinging the universal arm 1. The length and angle can be flexibly adjusted according to actual needs. This design allows the collection hood 201 to cover a wider range and adapt to pollution sources at different heights and locations. For example, within the working height of 10-14 meters, the extension height reaches 14-16 meters, which can effectively collect paint mist generated at different locations. Compared with fixed-position air collection equipment, it has a wider coverage range and is more practical.

[0032] Meanwhile, as the collection hood 201 moves along with the working surface of the top spray gun of the lifting frame, the suction of the external high-pressure air pump is used to conduct the air through the air extraction pipe 205 to the air supply pipe 207 of the steel wire hose 206, and finally a negative pressure is formed in the collection hood 201, so as to collect the paint mist generated during the ship painting operation in a timely manner to protect the environment and the health of workers.

[0033] Furthermore, during the paint mist collection process, the tilting and guiding action of the four guide plates 204 can be used to guide the movement direction of the paint mist, thereby improving the effectiveness of paint mist collection. At the same time, when the spray gun is tilted, the angle of the guide plate 204 near the spray gun can be adjusted to achieve targeted collection of paint mist. During the angle adjustment of the guide plate 204, the motor 306 (model RS-750) is started, which drives the winding reel 303 of the drive rod 302 to rotate. During the rotation of the winding reel 303, the pull rope 304 is wound or released. Under the action of tension and the elastic force of the return component, the angle of the guide plate 204 is increased or decreased. By adjusting the angle of the guide plate 204, a "directional negative pressure zone" is formed, which facilitates the guidance of paint mist to converge towards the air inlet, thereby improving the capture ability of diffused paint mist and reducing the risk of paint mist leakage.

[0034] Example 2

[0035] Please see Figure 3 This embodiment further illustrates Example 1. The pullback assembly shown in the figure includes a pullback plate 401 disposed on one side of the collection cover 201. One end of the rotating shaft 203 passes through the collection cover 201 and is connected to the pullback plate 401. A torsion spring 402 is sleeved on the side wall of the rotating shaft 203. The two ends of the torsion spring 402 are respectively connected to the pullback plate 401 and the side wall of the collection cover 201.

[0036] It should be noted here that: by setting up the return component, the elastic force of the torsion spring 402 can provide a return force to the diversion plate 204, which can then be used to provide driving force when the diversion plate 204 is adjusted in angle. On the other hand, it can provide an elastic tensile force to the diversion plate 204, so that the diversion plate 204 can maintain relative stability under the action of the elastic force of the torsion spring 402 and the tension of the pull rope 304.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
