When spraying, this type of surface spraying device generally has the following problems: First, the engineering pipeline is supported on rollers throughout the spraying process, and the rollers will continuously roll over the sprayed coating on the surface of the engineering pipeline. Second, this type of spraying device is based on single - station construction. When replacing a new engineering pipeline to be sprayed, the spraying mechanism is in a waiting state.

[0024] Embodiment 1
[0025] As Figure 1 shown, a spraying device for the surface of an engineering pipeline, the object it processes is the engineering pipeline 13 shown in the figure. Such engineering pipelines 13 are generally connected in a head-to-tail docking manner during engineering construction. Therefore, as shown in the figure, there is usually an enlarged head as a socket for accommodating the tail of another pipeline, and the tail is basically a straight pipeline body. Many of these engineering pipelines are metal casting pipes, and some are rubber and plastic pipes.
[0026] The spraying device for the surface of the engineering pipeline in this embodiment includes a multi-station pipe placement mechanism and a clamping and rotating mechanism.
[0027] Specifically, the above-mentioned multi-station pipe placement mechanism and clamping and rotating mechanism are arranged on the base 1. The multi-station pipe placement mechanism includes a slide rail III 4 arranged on the base 1 and two slide blocks III 7 cooperating with the slide rail III 4. Two support seats 14 are arranged on each slide block III 7, and the engineering pipeline 13 is placed on the support seats 14.
[0028] Furthermore, a semi-circular hole matching the outer shape of the engineering pipeline 13 is arranged on the upper part of the support seat 14. Preferably, a number of rotatable support rollers 15 are installed on the upper part of the support seat 14. A slide block III driving device is arranged on the slide block III 7. The slide block III driving device includes a rack 16 arranged on the base 1, a moving motor 18 on the slide block III 7, and a gear 17 connected to the output shaft of the moving motor 18. The gear 17 cooperates with the rack 16.
[0029] Preferably, in order to accurately position the slide block III 7, the moving motor 18 is equipped with an encoder, so that after the spraying station is debugged, the slide block III 7 can accurately stop moving every time it is at the spraying station for clamping.
[0030] The above clamping and rotating mechanism includes a slide rail I 2 and a slide rail II 3 that are fixedly arranged on the base 1 and are perpendicular to the direction of the slide rail III 4. A slide block I 5 that cooperates with the slide rail I 2 is installed on the slide rail I 2. An expansion rod I 8 is fixedly connected to the upper part of the slide block I 5. The other end of the expansion rod I 8 is connected to a fixed sleeve 10. The right clamping ring 12 is installed on the fixed sleeve 10 through a bearing 11. A slide block II 6 that cooperates with the slide rail II 3 is installed on the slide rail II 3. An expansion rod II 9 is fixedly connected to the upper part of the slide block II 6. The other end of the expansion rod II 9 is connected to a rotating motor base 21. A rotating motor 20 is fixedly installed on the rotating motor base 21. The output shaft of the rotating motor 20 is connected to a left clamping block 19.
[0031] The reason why the right clamping ring 12 is made into a ring shape is that when internally spraying the engineering pipeline 13, the nozzle of the spraying device can extend into the engineering pipeline 13 from the central hole of the right clamping ring 12. Therefore, the holes of the right clamping ring 12 and the fixed sleeve 10 are preferably aligned, just like Figure 1 shown in
[0032] In the case where the right clamping ring 12 is made into a ring shape, there is no need to require a central hole for the left clamping block 19.
[0033] Generally, the present invention does not limit the contact form between the left clamping block 19 and / or the right clamping ring 12 and the side surfaces at both ends of the engineering pipeline 13. For equipment dedicated to lightweight engineering pipelines, the clamping and lifting of the engineering pipeline can be achieved only through frictional force. For engineering pipelines with a relatively large weight, the clamping and lifting effect can be ensured by appropriately clamping the left clamping block 19 and / or the right clamping ring 12 with the side surfaces at both ends of the engineering pipeline 13.
[0034] Since the clamping force on the engineering pipeline 13 comes from both sides, the above-mentioned appropriate clamping only requires a small clamping dimension of several millimeters. For example, in this embodiment Figure 1 it can be seen that the left side edge of the right clamping ring 12 has a small protrusion, which can produce a certain clamping effect with the pipe end of the engineering pipeline 13 without affecting spraying. Although the contact surface between the left clamping block 19 and the engineering pipeline 13 is not shown, similar settings can obviously be made if necessary.
[0035] For the clamping on the left side, that is, the side with a swollen dimension, in order to control the dimensions of the components, while satisfying a sufficient frictional contact area, the outer diameter of the left clamping block 19 is controlled to be not greater than 1.2 times the outer diameter of the same side of the engineering pipeline 13.
[0036] Such as Figure 2As shown, a set screw 22 is provided between the slide rail II 3 and the slide block II 6. Based on the same principle and structure, set screws are also provided between the slide rail I 2 and the slide block I or between the slide rail III 4 and the slide block III 7 for fastening and fixing after the position is set.
[0037] The usage steps of this technical solution are as follows:
[0038] In the initial state, the two slide blocks III 7 are respectively on both sides of the spraying station. That is, the feeding stations are respectively on both sides of the spraying station. When in the feeding stations, the upper space is open, which is more beneficial for the hoisting operation of the engineering pipeline 13. When the materials are prepared on one side, start the moving motor 18 to move the slide block III 7 to the spraying station. Then, adjust the positions of the slide block I 5 and the slide block II 6 respectively, and clamp the two ends of the engineering pipeline 13 with the left clamping block 19 and the right clamping ring 12. At the same time, extend the telescopic rod I 8 and the telescopic rod II 9 so that the engineering pipeline 13 is separated from the support seat 14. Start the rotating motor 20, and the rotating motor 20 drives the engineering pipeline 13 to rotate. Use the outer surface spraying mechanism or the inner surface spraying mechanism of the pipe to spray the outer surface and the inner surface of the engineering pipeline 13. During the rotary spraying process, the support seat 14 no longer has any contact with the outer circumference of the engineering pipeline. In particular, the support roller 15 will not roll the sprayed material, further improving the quality of the spraying operation.
[0039] After spraying, lower the engineering pipeline 13 to make it fall back on the support seat 14, loosen the clamping at both ends, move the slide block III 7 out of the spraying station, and then move the slide block III 7 on the other side in. As Figure 3 shown, the engineering pipeline 13 on the left feeding station in this figure is moved to the spraying station, and the feeding operation can be carried out at the right feeding station. When the spraying operation is over, the engineering pipeline 13 can be moved to the left feeding station, and the engineering pipeline 13 on the right is moved to the spraying station, and so on in a cycle.
[0040] In another alternative embodiment, the slide rail I 2 and the slide rail II 3 are also arranged on the slide block III 7, and two sets of clamping and rotating mechanisms are also provided, so that the clamping and rotating mechanisms follow the pipe placement mechanism at each station. In this way, during the preparation stage, the clamping and rotation of the engineering pipeline 13 can be realized, and there is no need to perform clamping and rotation at the spraying station, further saving the preparation time. However, this embodiment requires an additional set of mechanisms, which will increase the cost of the equipment. The appropriate method can be selected by comprehensively considering the production efficiency and production cost.
[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
