Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a wall-penetrating pipeline positioning device. Background Art

[0002] In construction projects, water pipes, drainage pipes, electrical conduit pipes and other pipes often need to pass through building walls, floor slabs and other structures during installation to achieve the connection and transmission needs of water, electricity, gas and other infrastructure between different spaces of the building; in the process of penetrating the wall, a pipe with an inner diameter larger than the outer diameter of the pipe is usually buried in the wall first, and then the pipe is placed in the center of the casing to ensure that the gap between the pipe and the casing is uniform, and finally the gap between the casing and the pipe is sealed with asbestos cement, fireproof materials, etc. to enhance its sealing and waterproof properties; among them, the central arrangement of the pipe in the casing is the construction focus and difficulty. If the pipe is not concentric with the embedded casing, it will not only affect the appearance quality and waterproof effect of the pipeline project, but also increase the uneven force of the pipeline system, affecting the structural stability and increasing maintenance costs.

[0003] In order to ensure that the pipeline is located in the middle of the casing, the existing technology usually inserts wooden wedges between the embedded casing and the pipeline to adjust the spacing, or manually straightens and directly plugs the sealing material. However, in practice, the above operation methods still have many shortcomings: inserting wooden wedges between the embedded casing and the pipeline is cumbersome to operate, and the wooden wedges have poor stability during use and are easy to loosen and shift. In the insertion process, the wooden wedges are prone to friction with the pipeline surface, causing damage to the anti-corrosion coating. Manual straightening relies solely on human visual judgment of the placement of the casing, which is highly subjective and inaccurate, requires a lot of manpower and time, and has low construction efficiency. The above methods all have problems such as poor pipeline centering accuracy, low construction efficiency, and unguaranteed construction quality. Summary of the Invention

[0004] The purpose of the utility model is to provide a wall-penetrating pipe positioning device to solve the problems existing in the above-mentioned prior art.

Compared with traditional methods, this device greatly simplifies the construction process, reduces the complexity and subjectivity of manual operation, and improves construction efficiency.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0029] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0031] In order to solve the problems of poor stability, large amount of manpower and time consumption, poor pipe centering accuracy, low construction efficiency and unguaranteed construction quality during the centering operation of wall-penetrating pipes in the existing technology, such as Figure 1-Figure 3 As shown, a wall-penetrating pipe positioning device includes a folding frame 1 with a regular polygonal cross-section, a driving mechanism 2 arranged on the folding frame 1 for driving the folding frame 1 to expand or contract, a plurality of external support members 3 arranged on the outside of the folding frame 1, and a plurality of support members 4 arranged on the inside of the folding frame 1 and adjustable in length. The folding frame 1 includes at least five folding members 5 and a plurality of hinged plates, and the folding members 5 are hinged at the head and tail through the hinged plates in sequence to form a regular polygonal folding frame 1.

[0032] It should be noted that the cross-section of the folding frame 1 after expansion and contraction can be a regular polygonal structure such as a regular pentagon, a regular hexagon, or a regular octagon. Preferably, six folding members 5 are connected to form a regular hexagonal structure. A plurality of external support members 3 and support members 4 should be arranged around the folding frame 1. The number of external support members 3 and support members 4 can be determined according to actual conditions.

[0033] When the positioning device is used, the device is first placed in the casing, and then the folding frame 1 is driven to expand by the driving mechanism 2, so that it changes from a contracted state to an expanded state, so that the multiple outer support members 3 on the outside of the folding frame 1 are in contact with the inner wall of the casing, thereby stably fixing the folding frame 1 in the casing to prevent it from moving. After the folding frame 1 is expanded, the lengths of the multiple support members 4 set on the inside of the folding frame 1 are adjusted according to the outer diameter of the pipeline, so that the lengths of the multiple support members 4 are consistent and can fit tightly against the outer wall of the pipeline, thereby ensuring that the pipeline is centered in the casing. Finally, asbestos cement, fireproof materials, etc. are used to fill the gap between the casing and the pipeline for sealing to enhance its sealing and waterproofness. After use, the multiple support members 4 set on the inside of the folding frame 1 are adjusted. The length of the support member 4 makes the multiple support members 4 away from the outer wall of the pipe, and then the folding frame 1 is driven to shrink by the driving mechanism 2, so that the multiple outer support members 3 are away from the inner wall of the casing, and the device can be taken out from the casing for subsequent reuse; this device can accurately control the position of the pipeline in the casing, ensuring that the pipeline is concentric with the casing, thereby improving construction accuracy and project quality, without the need for tedious wooden wedge insertion or long manual straightening operations, only needs to place the device in the casing, adjust the expansion degree of the folding frame through the driving mechanism, and use the adjustable support member to fix the position of the pipeline, so as to quickly complete the positioning and centering of the pipeline, greatly improving construction efficiency, simplifying the construction process, reducing the complexity and subjectivity of manual operation, and improving construction efficiency.

[0034] Among them, such as Figure 2As shown, the folding member 5 includes: a first connecting rod 6 and a second connecting rod 7, wherein the first connecting rod 6 and the second connecting rod 7 are hinged at their middle parts to form an X-shaped folding member 5;

[0035] The hinged plate includes a front hinged plate 8 and a rear hinged plate 9. The top ends of the multiple folding parts 5 are hinged in sequence through the front hinged plate 8, and the bottom ends are hinged in sequence through the rear hinged plate 9. The multiple external support members 3 are respectively arranged on the multiple rear hinged plates 9, and the multiple support members 4 are respectively arranged on the multiple front hinged plates 8. The driving mechanism 2 is arranged between any front hinged plate 8 and its corresponding rear hinged plate 9.

[0036] Multiple folding parts 5 are hinged end to end through the front hinge plate 8 and the rear hinge plate 9 to form a retractable and adjustable regular polygonal frame structure that can adapt to sleeves of different diameters, making the device very versatile and applicable in a wide range of applications; the regular polygonal frame structure can also provide good support and stability, ensuring that the pipe maintains a stable central position in the sleeve, and can be retracted to reduce the volume after use, making it easy to carry and store.

[0037] like Figure 1 As shown, the driving mechanism 2 includes: a sleeve 10 fixedly connected to the outer wall of the front hinged plate 8 and passing through the upper and lower parts, a threaded rod 11 with one end fixedly connected to the rear hinged plate 9 and the other end passing through the sleeve 10, and a rotating sleeve 12 threadedly sleeved on the outside of the threaded rod 11 and rotatably connected to the sleeve 10.

[0038] Among them, the working principle of the driving mechanism 2 is: the rotating sleeve 12 arranged on the outside of the threaded rod 11 is rotated to make the rotating sleeve 12 move up and down on the threaded rod 11, thereby pushing the sleeve 10 connected to the front hinge plate 8 and rotatably connected to the rotating sleeve 12 to move, thereby changing the relative position between the front hinge plate 8 and the rear hinge plate 9, and finally realizing the extension and retraction of the entire frame, with a simple structure and convenient operation.

[0039] like Figure 3 As shown, the support member 4 includes: a fixed cylinder 13 that passes through the front hinge plate 8, is hollow inside and is open at one end inside the folding frame 1, a movable cylinder 14 that is slidably arranged in the fixed cylinder 13 and is hollow inside, a threaded adjustment rod 15 with one end threadedly connected to the movable cylinder 14 and the other end rotating through the side wall of the fixed cylinder 13, an inner arc plate 16 provided at the end of the movable cylinder 14, and a knob 17 provided at the outer end of the threaded adjustment rod 15, and a scale line 18 is provided on the outer side wall of the movable cylinder 14.

[0040] It should be noted that: in actual use, the support member 4 should be set on the outside of the sleeve, so that the staff can adjust the length of the support member 4 after the device is fixed in the sleeve; the working principle of adjusting the length of the support member 4 is: rotating the threaded adjustment rod 15, the movable cylinder 14 can slide in the fixed cylinder 13, thereby adjusting the contact position and tightness of the inner arc plate 16 with the inner wall of the pipe, and the setting of the scale line 18 on the movable cylinder 14 can help to accurately control the extension length of the movable cylinder 14, that is, to accurately adjust the position of each inner arc plate 16, ensure that the pipe and the sleeve 10 are set concentrically, and effectively improve the positioning accuracy.

[0041] like Figure 1 As shown, the outer support member 3 includes: a connecting block 19 fixedly connected to the outer side wall of the rear hinge plate 9, an outer arc plate 20 connected to the connecting block 19, and a rubber pad 21 arranged on the outer side of the outer arc plate 20; the rubber pad 21 can increase the friction between the outer arc plate 20 and the outer wall of the pipe, prevent the folding frame 1 from sliding, and thereby improve the stability and safety of the device during use.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described with reference to the preferred embodiments of the present invention, those skilled in the art should understand that various changes can be made in form and details without departing from the spirit and scope of the present invention as defined in the appended claims.
