Description

Technical Field

[0001] This invention relates to the field of pipeline installation engineering technology, and in particular to a pipeline sleeve positioning and straightening device. Background Technology

[0002] During the construction of pipelines in building projects, it is necessary to fill the gap between the pipeline and the sleeve that penetrates the wall or floor slab with sealant. At this time, the centered arrangement and positioning of the pipeline within the sleeve becomes a difficult point in the construction.

[0003] Currently, the common method for centering the pipe within the sleeve is to weld steel bars between the sleeve and the pipe or to manually straighten it. Then, sealant is filled between the pipe and the sleeve penetrating the wall or floor. While this method ensures the sleeve's positioning and centering, it results in significant waste of steel bars during fixing. Furthermore, the steel bars need to be cut after filling with sealant, leading to high labor costs. The cutting and welding of steel bars also increases mechanical and welding work, requiring cutting and welding equipment and temporary power supplies to be moved with the work site, increasing the risk of mechanical injury and hot work. Therefore, there is a need to develop a simple and convenient device for centering and positioning sleeves on pipes to meet the requirements of sleeve construction. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a simple and convenient pipe sleeve positioning and straightening device that can replace the traditional method of using welded steel bars for straightening, greatly improving construction efficiency and eliminating safety hazards during operation.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A pipe sleeve positioning and straightening device is provided, which includes a positioning claw and a push rod. The positioning claw includes an upper positioning claw, a lower positioning claw, and a connecting body connecting one end of the upper positioning claw and the lower positioning claw. The connecting body is provided with a through hole for the push rod to pass through. The upper positioning claw has an arc-shaped part at one end near the connecting body. The upper positioning claw and the lower positioning claw are provided with ratchet teeth on their opposite inner sides at the other ends away from the connecting body. One end of the push rod passes through the through hole and is provided with a ratchet. The upper and lower ends of the ratchet can engage the ratchet teeth.

[0007] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, an end positioning plate is further included, wherein the end positioning plate is disposed at one end of the upper positioning claw or the lower positioning claw located on the connecting body.

[0008] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the lower positioning claw is further provided with a top rod limiting block between the connecting body and the ratchet, and the top rod limiting block is provided with a through groove coaxial with the through hole.

[0009] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the through hole is configured as a U-shaped slot opening toward one side of the positioning claw.

[0010] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the other end of the top rod is provided with an adjustment handle.

[0011] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the bottom surface of the lower positioning claw is configured as an inwardly concave cross-section with an arc or triangular structure.

[0012] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the positioning claw and the top rod are integrally molded, and the molding method includes 3D printing, injection molding or casting.

[0013] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the straightening device is in a group of at least three, and the straightening device is evenly distributed between the pipe and the sleeve.

[0014] In a preferred embodiment of the pipe sleeve positioning and straightening device provided by the present invention, the straightening device is located at the same end or different ends of the sleeve.

[0015] The present invention also provides a construction method for using the pipe sleeve positioning and straightening device described in the above embodiments, comprising the following steps:

[0016] Step 1: After the initial pre-embedded sleeve construction is completed, during pipeline installation, the secondary pre-embedded sleeve is inserted into the pipeline;

[0017] Step 2: Move the secondary pre-embedded sleeve to a fixed position and use the straightening device to align the secondary pre-embedded sleeve on the pipeline;

[0018] Step 3: Construct the wall and fix the secondary embedded sleeve;

[0019] Step 4: Remove the straightening device and fill the gap between the secondary pre-embedded sleeve and the pipeline with sealing material to complete the construction.

[0020] Compared with the prior art, the advantages of the pipe sleeve positioning and straightening device provided by the present invention are:

[0021] I. The positioning claw designed in this invention has an arc-shaped part on the upper positioning claw, so that the ratchet teeth on the inner sides of the upper and lower positioning claws form an angle, and the angle is an acute angle.

[0035] Example 1

[0036] Please see Figures 1-6 This embodiment provides a pipe sleeve positioning and straightening device 1. The straightening device 1 includes a positioning claw 11 and a push rod 12. The positioning claw 11 includes an upper positioning claw 111, a lower positioning claw 112, and a connecting body 113 connecting one end of the upper positioning claw 111 and the lower positioning claw 112. The connecting body 113 is provided with a through hole 1130 for the push rod 12 to pass through. The upper positioning claw 111 has an arc-shaped portion 1112 at one end near the connecting body 113. Figure 1As shown, the design of the arc-shaped part 1112 makes the upper positioning claw 111 and the lower positioning claw 112 form an angle at the end away from the connector 113, and the angle is an acute angle. On the other hand, it ensures that the positioning claw will not be obstructed during the placement of the positioning claw in the pipe and sleeve, and no additional tools are required. The upper positioning claw 111 and the lower positioning claw 112 are provided with ratchet teeth 110 on the opposite inner side of the other end away from the connector 113. One end of the push rod 12 passes through the through hole 1130 and is provided with a ratchet 120. The upper and lower ends of the ratchet 120 can engage the ratchet teeth 110.

[0037] Preferably, the other end of the push rod 12 is provided with an adjusting handle 122, which facilitates the control of the rotation of the push rod and also facilitates the pressing of the push rod.

[0038] The positioning claws designed in this embodiment have an arc-shaped portion on the upper positioning claw, so that the ratchet teeth on the inner sides of the upper and lower positioning claws form an angle, and the angle is an acute angle. The opening of the positioning claws is controlled by pressing in the ratchet of the top rod. Through the action of multiple positioning claws, the sleeve is stably and accurately positioned outside the pipeline. It is simple and convenient to use, which greatly improves the construction efficiency. Moreover, there are no safety hazards of mechanical injury and hot work during the construction process, which reduces the construction difficulty and also reduces material and labor costs.

[0039] In use, place the positioning claw into the gap between the pipe and the sleeve, and simultaneously press the push rod. The push rod gradually pushes into the positioning claw, and the ratchet at the head of the push rod squeezes and expands the pawl, locking it with the ratchet teeth until the sleeve is secured by the positioning claw. Stop pressing the push rod when you hear a clicking sound from the positioning claw's groove and the push rod due to the locking pressure. Using this method, insert multiple positioning claws simultaneously into the gap between the sleeve and the pipe, controlling the opening degree of the multiple positioning claws to be consistent, thereby achieving the centered position of the pipe within the sleeve. After construction is completed, during disassembly, simply rotate the push rod to disengage the ratchet teeth, and the positioning claw will retract to its original state. At this point, the straightening device can be removed from the sleeve.

[0040] Example 2

[0041] Based on Embodiment 1, the positioning claw 11 in this embodiment is further designed with an end positioning plate 114, which is located at one end of the connecting body 113 where the upper positioning claw 111 or the lower positioning claw 112 is located. Figure 1 As shown, in this embodiment, the end positioning plate is located at one end of the connecting body where the upper positioning claw is located. In other embodiments, it may be located at one end of the connecting body where the lower positioning claw is located (not shown in the figure).

[0042] The end positioning plate design described in this embodiment can be used to position the positioning claw between the pipe and the sleeve for end positioning, which is convenient to use.

[0043] Example 3

[0044] Based on Embodiment 1 or Embodiment 2, in this embodiment, the lower positioning claw 112 is further provided with a push rod limiting block 1122 between the connecting body 113 and the ratchet 110. The push rod limiting block 1122 is provided with a through groove 1120 coaxial with the through hole 1130. The design of the push rod limiting block in this embodiment serves as a limit in the radial direction of the push rod, preventing the ratchet of the push rod from disengaging from the ratchet of the positioning claw, and ensuring the structural stability of the positioning claw.

[0045] Example 4

[0046] Based on any of the above embodiments, the through hole 1130 in this embodiment is configured as a U-shaped slot opening toward one side of the positioning claw 11, such as... Figure 3 or Figure 5 As shown, in this embodiment, the through hole is designed as a U-shaped slot structure that opens to one side, which facilitates the installation and disassembly of the top rod.

[0047] Example 5

[0048] Based on Example 1, please refer to Figure 2 and Figure 3 In this embodiment, the bottom surface of the lower positioning claw 112 is designed to be concave inward and has a triangular cross-section.

[0049] Example 6

[0050] Unlike Example 5, please refer to Figure 4 and Figure 5 In this embodiment, the bottom surface of the lower positioning claw 112 is designed with an inwardly concave cross-section in an arc shape.

[0051] Example 7

[0052] Based on any of the above embodiments, the positioning claw 11 and the top rod 12 of this embodiment are integrally molded, and the molding method includes 3D printing, injection molding or casting, and the molding material is rigid PVC or metal or other malleable materials.

[0053] Example 8

[0054] Based on any of the above embodiments, the straightening devices 1 in this embodiment are grouped in sets of at least three, and the straightening devices 1 are evenly distributed between the pipe 2 and the sleeve 3. Optionally, the straightening devices 1 are located at the same end or different ends of the sleeve 3.

[0055] This embodiment is described in groups of four. The straightening devices are arranged in the vertical and horizontal directions between the sleeve and the pipe. The straightening devices in the vertical and horizontal directions are located at the same end or different ends of the sleeve.

[0056] In practical implementation: it can be applied to the construction of secondary pre-embedded sleeves for pipelines, such as... Figure 7 and Figure 8 As shown, the primary embedded sleeve for the pipe penetrating the wall or floor slab is used. Where a secondary embedded sleeve is required, it is then fitted onto the pipe. For example... Figure 8 As shown, the straightening device is used to align the secondary embedded sleeve, ensuring the pipe is centered within it. Then, the wall is constructed. After the wall is built, the straightening device is removed (it can be reused later). Sealing material is then filled between the pipe and the secondary embedded sleeve to complete the construction. Figure 9 As shown.

[0057] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
