DETAILED DESCRIPTION

[0029] The following is a detailed description of the pipe liner support device and its construction method proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0030] The following describes the embodiments of the present invention through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner, and the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components during actual implementation. During actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0031] Throughout the specification and claims, certain terms are used to refer to specific system components. As one skilled in the art will appreciate, different companies may use different names for a component. This document does not intend to distinguish between components that differ in name but function identically. Throughout the specification and claims, the terms "including" and "comprising" are used in an open-ended manner and, thus, should be interpreted to mean "including, but not limited to..."

[0032] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0033] In addition, each embodiment described below has one or more technical features. However, this does not mean that users of the present invention must implement all technical features in any embodiment at the same time, or that they can only implement some or all technical features in different embodiments separately. In other words, as long as implementation is possible, those skilled in the art can, based on the disclosure of the present invention and depending on design specifications or implementation requirements, selectively implement some or all technical features in any embodiment, or selectively implement a combination of some or all technical features in multiple embodiments, thereby increasing the flexibility of the implementation of the present invention.

[0034] In order to make the purpose and features of the present invention more obvious and easy to understand, the specific embodiments of the present invention are further described below with reference to the accompanying drawings. However, the present invention can be implemented in different forms and should not be considered as being limited to the described embodiments.

[0035] Please refer to Figures 1 to 3 , Figure 1 Schematic diagram of the pipe lining support device in this embodiment; Figure 2 yes Figure 1 Right view; Figure 3 yes Figure 1 A top view of the . Figure 1 、 Figure 2 and Figure 3 As shown, the pipe lining support device 100 includes: an adsorption structure 1, a rotating ring 2, a control structure 3, a bracket 4 and two rollers 5; the adsorption structure 1 is set on the outer edge of the rotating ring 2, the control structure 3 is set on the bracket 4 and engages with the inner edge of the rotating ring 2 to drive the rotating ring 2 to rotate and adjust the position of the adsorption structure 1; the two rollers 5 are respectively set in two gaps between the rotating ring 2 and the bracket 4 (that is, the bracket 4 and the rotating ring 2 are connected by the rollers 5), supporting the rotation of the rotating ring 2 on the bracket 4 and limiting the position of the rotating ring 2 after the adjustment. Based on the adsorption structure 1, the pipe lining is transported, adsorbed and supported; based on the rotating ring 2 transmitting force by engaging with the control structure 3, it drives the rotating ring 2 to rotate, thereby achieving the position change of the adsorption structure 1, and finally achieving the adjustment of the position of the pipe lining adsorbed by the adsorption structure 1. The entire process is mechanized, eliminating the need for manual handling and support of the pipe lining, reducing construction safety risks.

[0036] Among them, such as Figure 1 As shown, the inner diameter of the rotating ring 2 is larger than the outer diameter of the middle pipe 6 of the pipeline, and is sleeved on the outer side of the middle pipe 6 to avoid the middle pipe 6; a gear component 21 is provided on the inner edge of the rotating ring 2 and protrudes from the outer edge of the rotating ring 2.

[0037] In this embodiment, the control structure 3 includes a gear 31, a ratchet 32, and a fixed plate 33. The gear 31 meshes with the gear component 21, and the fixed plate 33 is disposed on the gear 31 and the ratchet 32. The ratchet 32 ​​cooperates with the fixed plate 33 to constrain and fix the position of the gear 31. The overall size of the gear 31 is smaller than the size of the "gear" formed by the inner edge of the rotating ring. Due to the meshing of the gear 31 with the gear component 21, when the gear 31 applies a force, the gear 31 drives the rotating ring 2 to rotate, thereby driving the adsorption structure 1 on the outer edge of the rotating ring 2 to rotate, ultimately driving the pipe lining adsorbed on the adsorption structure 1 to rotate, adjusting the position of the pipe lining relative to the pipe, enabling installation of the pipe lining at different locations and subsequent welding construction. Preferably, the gear 31 is a hand-cranked gear, i.e., the driving source is an external force. This hand-cranking method reduces live work and eliminates the need for wire pulling, ensuring ease of construction.

[0038] Furthermore, the suction structure 1 includes at least two suction cups 11 and a bracket 12. The at least two suction cups 11 are positioned on the outer edge of the rotating ring 2 via the bracket 12. The suction cups 11 are used to secure the pipe lining. The bracket 12 distances the suction cups 11 from the rotating ring 2, facilitating subsequent welding operations on the pipe lining. It is understood that the suction structure 1 may include only the suction cups 11 without the bracket 12, as long as it satisfies the purpose of securing the pipe lining.

[0039] Please refer to Figure 1 and Figure 4 , Figure 4 Schematic diagram of the structure of the roller in this embodiment. Figure 1 and Figure 4 As shown, the roller 5 comprises a cylindrical body 51, a socket 52 formed in the cylindrical body 51, and a latch 53 used in conjunction with the socket 52. The cylindrical shape of the roller 5 supports the rotation of the rotating ring 2, acting as a rotating bracket on the bracket 4 that supports the rotating ring 2. The latch 53 in the roller 5 cooperates with the socket 52 in the body to lock the rotating ring 2 in place relative to the bracket 4.

[0040] Please continue to refer to Figure 1 The bracket 4 includes: two legs 41 and two cross bars 42. The two cross bars 42 are arranged between the two legs 41 to form a stable fixed support infrastructure. Since the two legs 41 are connected by the cross bars 42, the construction is not affected and the workers can walk normally.

[0041] It can be understood that the above examples are merely examples listed for a better understanding of the technical solutions of the embodiments of the present application, and are not intended to be the sole limitation on the embodiments.

[0042] Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required for this application.

[0043] Correspondingly, this embodiment also provides a construction method for a pipe lining support device. Figure 1 and Figure 5 The construction method of the pipe lining support device described in this embodiment is described in detail.

[0044] First, step S1 is performed to install the pipe lining support device 100 in place; wherein the pipe lining support device 100 is in the pipe 8, and the rotating ring of the pipe lining support device 100 is sleeved on the outside of the middle conduit 6 of the pipe 8;

[0045] Next, step S2 is executed, wherein the pipe liner is sucked up by the adsorption structure 1, and the rotating ring is driven to rotate by the control structure 3 to drive the pipe liner 7 to a specified position, and the position of the rotating ring after adjustment is fixed by the control structure 3 and the roller 5;

[0046] Next, step S3 is executed to perform welding construction on the pipe lining 7, and the pipe lining support device 100 maintains adsorption support until the welding is completed.

[0047] It can be understood that since the pipe lining pipe is made of four pieces of pipe linings spliced ​​and welded together at staggered seams, each piece of pipe lining is transported to the corresponding designated position using a pipe lining support device, and then maintained with adsorption support until the current pipe lining completes the welding construction (corresponding to executing steps S2-S3).

[0048] As for the method disclosed in the embodiment, since it corresponds to the structure disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the structure part.

[0049] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
