Description

Technical Field

[0001] The utility model relates to the technical field of ductile iron pipe transportation, and particularly relates to a casing device for ductile iron pipes. Background Art

[0002] The traditional technological process is as follows: After the ductile iron pipes are finished products, they are transported to the construction site by trucks or trains. During the transportation process, most of them are transported with single pipes placed independently. When a certain number of pipes are transported to the construction site, the freight is very expensive. This low loading rate not only wastes the carrying capacity of the transportation tools, but also increases the number of transportation times and costs.

[0003] However, at present, due to the long length and large diameter of the ductile iron pipes, it is not convenient to realize the safe and stable nesting between ductile iron pipes with different diameters. In addition, circular pipes are more likely to move unstably during the nesting process, increasing the difficulty of nesting. Summary of the Utility Model

[0004] The utility model provides a casing device for ductile iron pipes to solve the technical problems in the prior art that when transporting ductile iron pipes, single-pipe transportation is adopted, which is not convenient for nesting large and small pipes and increases the transportation cost.

[0005] To solve the above problems, the casing device for ductile iron pipes provided by the utility model adopts the following technical solutions:

[0006] It includes a chain conveyor mechanism for transporting large-diameter ductile iron pipes and a roller conveyor mechanism arranged on one side of the chain conveyor mechanism for transporting small-diameter ductile iron pipes. The conveying direction of the chain conveyor mechanism is perpendicular to the conveying direction of the roller conveyor mechanism. A support platform is provided at one end of the roller conveyor mechanism close to the chain conveyor mechanism. An electromagnetic suction trolley for moving and supporting one end of the small-diameter ductile iron pipe is arranged on the support platform. The electromagnetic suction trolley includes a bottom plate. A moving component is provided at the bottom of the bottom plate. A magnet for adsorbing on the outer surface of the small-diameter ductile iron pipe is provided at the upper end of the bottom plate. A driving component for lifting the large-diameter ductile iron pipe and driving it to move up and down is arranged between the two chains of the chain conveyor mechanism.

[0007] Further, the moving component includes a support cross shaft. Oblique support shafts are provided at both ends of the support cross shaft. Rollers are rotatably arranged on the oblique support shafts.

[0008] Further, connecting plates are provided on both sides of the bottom of the bottom plate. An arc-shaped groove for cooperating with the support cross shaft is provided at the bottom of the connecting plate. The support cross shaft is clamped in the arc-shaped groove and is welded to the connecting plate.

[0009] Further, a support block is provided on one side of the upper end of the bottom plate. A support plate is provided on the upper end of the support block. A card slot is formed between the support plate and the bottom plate, and the magnet is placed in the card slot.

[0010] Further, the upper surface of the support plate is in a concave arc shape and a working rod extending forward is provided at one end of the support plate.

[0011] Further, the roller in the roller conveying mechanism is a V-shaped roller.

[0012] Further, the driving assembly includes a support plate. The cross-section of the support plate is in a concave arc shape, and a telescopic member for driving its lifting is provided at the bottom end of the support plate.

[0013] Further, the driving assemblies are two groups distributed at intervals along the axial direction of the large-diameter ductile iron pipe thereon.

[0014] The beneficial effects of the ductile iron pipe casing device provided by the present utility model are as follows: In specific use, the automated operations of the chain conveying mechanism and the roller conveying mechanism reduce the need for manual operation. In addition, the design of the chain conveying mechanism and the roller conveying mechanism and the cooperation with the magnetic suction trolley can realize the sleeving of small-diameter ductile iron pipes into large-diameter ductile iron pipes. The automated sleeving of large-diameter and small-diameter ductile iron pipes significantly reduces the need for transport vehicles, thereby reducing the transportation cost.

Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The quantity of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0026] Next, with reference to several representative implementation manners of the present invention, the principles and spirits of the present invention will be elaborated in detail.

[0027] An embodiment of the ductile iron pipe casing device provided by the present invention:

[0028] As Figures 1 to 3 shown, it includes a chain conveying mechanism 1 for conveying large-diameter ductile iron pipes and a roller conveying mechanism 2 provided on one side of the chain conveying mechanism 1 for conveying small-diameter ductile iron pipes. The conveying direction of the chain conveying mechanism 1 is perpendicular to the conveying direction of the roller conveying mechanism 2. A support platform 21 is provided at one end of the roller conveying mechanism 2 close to the chain conveying mechanism 1. A magnetic suction trolley 3 for moving and supporting one end of a small-diameter ductile iron pipe is provided on the support platform 21. The magnetic suction trolley 3 includes a bottom plate 31. A moving assembly 32 is provided at the bottom of the bottom plate 31. A magnet 33 for adsorbing on the outer surface of a small-diameter ductile iron pipe is provided at the upper end of the bottom plate 31. A driving assembly 11 for lifting a large-diameter ductile iron pipe and driving it to move up and down is provided between the two chains of the chain conveying mechanism 1.

[0029] The automated operations of the chain conveyor mechanism 1 and the roller conveyor mechanism 2 reduce the need for manual operation. Additionally, the design of the chain conveyor mechanism 1 and the roller conveyor mechanism 2, in cooperation with the magnetic suction trolley 3, can automatically place ductile iron pipes with a small diameter into ductile iron pipes with a large diameter, significantly reducing the need for transport vehicles and thus lowering the transportation cost.

[0030] In this embodiment, the moving component 32 includes a support cross-axis 321. Oblique support shafts 322 are provided at both ends of the support cross-axis 321, and rollers 323 are rotatably provided on the oblique support shafts 322.

[0031] By supporting the rollers 323 through the oblique support shafts 322, the oblique support of the rollers 323 can be realized, facilitating the movement of the two rollers 323 along the inner wall of the ductile iron pipe with a large diameter.

[0032] Wherein, connecting plates 311 are provided on both sides of the bottom of the bottom plate 31. An arc-shaped groove for cooperating with the support cross-axis 321 is provided at the bottom of the connecting plate. The support cross-axis 321 is clamped in the arc-shaped groove and is welded to the connecting plate 311.

[0033] The design of the connecting plate 311 and the arc-shaped groove enables the magnetic suction trolley 3 to have good adaptability and stability.

[0034] Wherein, a support block 312 is provided on one side of the upper end of the bottom plate 31. A support plate 313 is provided at the upper end of the support block 312. A clamping groove 314 is formed between the support plate 313 and the bottom plate 31, and the magnet 33 is clamped in the clamping groove 314.

[0035] The magnet 33 is fixed between the support plate 313 and the bottom plate 31 by being clamped in the clamping groove 314. This installation method is very simple and does not require complex fixing tools or steps. The clamping groove 314 provides a stable support and fixing environment for the magnet 33, reducing the direct friction and collision of the magnet 33 with surrounding components during operation, thereby reducing wear.

[0036] In this embodiment, the upper surface of the support plate 313 is a concave arc surface, and a working rod 3130 extending forward is provided at one end of the support plate 313.

[0037] During specific use, after the magnetic suction trolley 3 completely enters the ductile iron pipe with a large diameter along with the ductile iron pipe with a small diameter, the working rod 3130 can be pulled at one end of the ductile iron pipe with a large diameter to pull out the magnetic suction trolley 3.

[0038] As Figure 5 shown, in this embodiment, the roller in the roller conveyor mechanism 2 is a V-shaped roller.

[0039] The V-shaped roller can be used for transportation and play a role in limiting the position at the same time.

[0040] As Figure 4 shown, in this embodiment, the driving assembly 11 includes a supporting plate 111, the cross-section of the supporting plate 111 is concave arc-shaped, and a telescopic member 112 for driving its lifting is provided at the bottom end of the supporting plate 111.

[0041] The telescopic member 112 is a cylinder, and in other embodiments, it can also be a hydraulic cylinder.

[0042] Among them, the driving assemblies 11 are two groups distributed at intervals along the axial direction of the large-diameter ductile iron pipe thereon.

[0043] By controlling the lifting of the large-diameter ductile iron pipe through the driving assembly 11, it can ensure that the small-diameter ductile iron pipe can be smoothly inserted into the large-diameter ductile iron pipe.

[0044] When specifically used for sleeving, after the large-diameter ductile iron pipe is transported to the driving assembly 11 through the chain conveying mechanism 1 and is lifted by the driving assembly 11, the small-diameter ductile iron pipe is transported towards one end close to the large-diameter ductile iron pipe through the V-shaped roller. When the end of the small-diameter ductile iron pipe passes by the magnetic adsorption trolley 3, due to the action of the magnet 33, it will be adsorbed on the outer wall of the small-diameter ductile iron pipe and enter the large-diameter ductile iron pipe together with the small-diameter ductile iron pipe. After the end enters, the rollers 323 of the magnetic adsorption trolley 3 walk along the inner wall of the large-diameter ductile iron pipe, playing a role in supporting the end of the small-diameter ductile iron pipe. Until it is completely sleeved, as Figure 6 shown, a wooden block spacer is placed between the inner wall of the large-diameter ductile iron pipe and the outer wall of the small-diameter ductile iron pipe, and then the magnetic adsorption trolley 3 can be taken out by pulling the operating rod 3130.

[0045] According to the above description of this specification, those skilled in the art can also understand the following terms used. For example, terms indicating orientation or position relationship such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or position relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above orientation or position relationship terms cannot be understood or interpreted as a limitation to the solution of the present invention.

[0046] In addition, in the description of this specification, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
