Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline coating auxiliary equipment, and in particular relates to a pipeline supporting and conveying device. Background Art

[0002] Ductile iron pipes have been widely used in water supply, drainage, heating and other fields. In order to ensure that the pipelines are protected from external soil corrosion during direct burial and from corrosion caused by ultraviolet rays, rainwater erosion, alternating dry and wet conditions during overhead use, it is usually necessary to apply an anti-corrosion coating on the outside of the ductile iron pipes.

[0003] After the anti-corrosion coating is applied to the outer wall of the ductile iron pipe, due to the certain thickness of the coating, it takes a long time to solidify, and it is difficult to quickly solidify in a short time to form a stable and hard coating. However, in order to meet the overall assembly line production, the ductile iron pipe with uncured coating will be placed horizontally on the conveyor belt so that the pipe fittings move with the conveyor belt into the next process for rapid curing. Therefore, the contact area between the outer wall of the pipe body and the conveyor belt is large, which can easily cause large-scale damage and shedding of the uncured coating on the outer wall of the pipe body. A large amount of coating repair work is required for subsequent repairs, which undoubtedly increases the workload and seriously affects the production efficiency of the overall pipeline products, which is not conducive to continuous production.

[0004] Therefore, a pipeline support and conveying device is now needed that can reduce the damaged area of ​​pipeline coating and reduce the workload of coating repair. Utility Model Content

[0005] The purpose of the utility model is to provide a pipeline support and transmission device, which can effectively reduce the contact area between the pipeline and the transmission device, reduce the damaged area of ​​the pipeline coating, and at the same time reduce the workload of coating repair, improve the production efficiency of pipeline products, and realize the continuous production of ductile iron pipes.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A pipeline support and transmission device includes a transmission device composed of a plurality of transmission chain plates connected end to end and a support adjustment device correspondingly arranged on the front and rear sides of the transmission chain plates, and the support adjustment device is adapted to the pipe fittings placed laterally on the transmission chain plates; the support adjustment device includes telescopic columns symmetrically arranged on the side walls of the transmission chain plates and supported on the outer walls of the pipe fittings, and a controller that respectively controls the telescopic activities of the two telescopic columns.

[0008] A further improvement of the technical solution of the utility model is that a "V"-shaped groove adapted to the pipeline is opened on the top of the transmission chain plate, and two telescopic columns are symmetrically located on both sides of the "V"-shaped groove.

[0009] A further improvement of the technical solution of the utility model is that the top surfaces of the two telescopic columns are relatively inclined to the outer walls of the adapter pipes or arc-shaped grooves are respectively provided.

[0010] A further improvement of the technical solution of the utility model is that when the controller controls the telescopic column to retract, the top surface of the telescopic column is lower than the inclined surface of the "V"-shaped groove.

[0011] A further improvement of the technical solution of the utility model is that an anti-slip pad is arranged on the top surface of the telescopic column.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0013] The utility model discloses a pipeline supporting and conveying device, which can effectively reduce the contact area between the pipeline and the transmission device, reduce the damaged area of ​​the pipeline coating and reduce the workload of coating repair, thereby improving the production efficiency of pipeline products and facilitating the continuous production of ductile iron pipes.

[0017] The present invention is further described in detail below in conjunction with the embodiments:

[0018] like Figure 1 and Figure 2 As shown, the utility model provides a pipeline support and conveying device, including a transmission device controlled by a motor and a support adjustment device arranged on the transmission device, wherein the transmission device is composed of a plurality of transmission chain plates 2 connected end to end, the support adjustment device is correspondingly arranged on the front and rear sides of the transmission chain plates 2, and the support adjustment device is adapted to the pipe fitting 1 laterally inverted on the transmission chain plates 2, that is, the two support adjustment devices cooperate to support the pipe fitting 1 along the length direction of the pipe fitting 1, one in front and one in back.

[0019] Specifically, the supporting and adjusting device includes two telescopic columns 4 and two controllers 3 for controlling the telescopic activities of the two telescopic columns 4. The controller can adopt an electric control system or a hydraulic control system, such as a hydraulic station. The two telescopic columns 4 are respectively symmetrically arranged on the side walls of the transmission chain plate 2. The two telescopic columns 4 are supported on the outer wall of the pipe fitting 1. Since the contact area of ​​the telescopic columns 4 is small, the contact area between the pipeline and the transmission device can be effectively reduced, the damaged area of ​​the pipeline coating can be reduced, and the workload of repairing the coating can be reduced, thereby improving the production efficiency of the pipeline products, which is conducive to the continuous production of ductile iron pipes.

[0020] A "V"-shaped groove adapted to the pipe 1 is provided on the top of the transmission chain plate 2, and two telescopic columns 4 of the support and adjustment device are symmetrically located on both sides of the "V"-shaped groove. In order to ensure that the telescopic column 4 can stably support the pipe 1, the diameter of the telescopic column 4 is between 5-50 mm, and the top surfaces of the two telescopic columns 4 of the support and adjustment device adapt to the outer wall of the pipe 1, and smoothly contact the outer wall of the pipe 1 to avoid local damage to the substrate due to the weight of the pipe 1. Preferably, the top surfaces of the two telescopic columns 4 are relatively inclined or arc grooves are respectively provided. In order to further achieve stable support for the pipe 1, an anti-slip pad can be provided on the top surface of the telescopic column 4 to increase the interaction force between the outer wall of the pipe 1 and the top surface of the telescopic column 4.

[0021] like Figure 1 As shown, before the coating on the outer wall of the pipe 1 is cured, the controller 3 in the support adjustment device located at the front and rear sides of the transmission chain plate 2 controls the telescopic column 4 to extend and support the outer wall of the pipe 1, so as to avoid direct contact between the pipe 1 and the "V"-shaped groove of the transmission chain plate 2, which may cause large-scale damage to the coating; Figure 2 As shown, after the coating on the outer wall of the pipe 1 is cured, the controller 3 controls the telescopic column 4 to retract. At this time, the top surface of the telescopic column 4 is lower than the inclined surface of the "V"-shaped groove, and the pipe 1 is placed on the "V"-shaped groove of the transmission chain plate 2 and transferred to the next process.
