Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and more specifically to a support device for supporting rods inserted inside pipes. Background Technology

[0002] In various construction scenarios, it is often necessary to pass rods through pre-set large-diameter pipes for directional construction operations. For example, in shield tunneling / TBM support projects, self-drilling anchors need to pass through positioning pipes and be driven into the surrounding rock to achieve structural reinforcement. However, in existing construction processes, the positioning accuracy of the rods during pipe insertion is difficult to control effectively, which can easily lead to large construction deviations and seriously affect construction efficiency and project quality. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an internal pipe support device for positioning and supporting rods inside a pipe, thereby reducing construction deviations by improving the insertion accuracy of the rods during construction.

[0004] The overall technical solution of this utility model is as follows:

[0005] This utility model addresses the problem of large construction deviations when existing rods are inserted into pipes during construction. Specifically:

[0006] In some existing construction scenarios, there is a process where positioning pipes need to be installed first, and then the rods are inserted into the positioning pipes for construction. To facilitate the insertion of the rods, the diameter of the positioning pipes is often much larger than the outer diameter of the rods. This causes the rods (especially longer rods) to become misaligned after being inserted into the positioning pipes, resulting in poor positioning accuracy. This makes it impossible to carry out the construction process according to the design requirements, which in turn easily leads to large construction deviations and seriously affects construction efficiency and project quality.

[0007] Based on this, the present invention provides an in-pipe support device for positioning and supporting rods inside a pipe. Using this in-pipe support device can improve the insertion accuracy of rods during construction, thereby reducing construction deviations and minimizing the possibility of reduced construction efficiency and project quality due to construction deviations.

[0008] Specifically, the tube support device of this utility model includes:

[0009] Proximal positioning disc with proximal positioning holes;

[0010] A distal positioning plate having a distal positioning hole spaced apart from the proximal positioning plate, wherein the proximal positioning hole and the distal positioning hole are aligned to form an insertion channel for positioning the rod insertion.

[0011] An elastic element, one end of which is connected to the proximal positioning disk and the other end of which is connected to the distal positioning disk, is configured to be elastic so that it can undergo elastic deformation under tension.

[0012] A support body used to abut against the inner wall of the pipe for support, with several supports spaced apart around the insertion channel;

[0013] For each support, one end is movably connected to the proximal positioning plate via a proximal connecting arm, and the other end is movably connected to the distal positioning plate via a distal connecting arm. This allows the support to be moved closer to the insertion channel by separating and moving the two positioning plates, so that several supports together form a snap-fit ​​structure that can be positioned and snapped into pipes of different diameters.

[0014] In the above scheme, alignment holes on the near-end and far-end positioning plates provide a "plugging channel" that penetrates the pipe and guides the inserted rod. Multiple supports within the pipe provide multi-point, all-around alignment and positioning of the rod. This effectively prevents the rod from swaying or bending inside the pipe due to its large diameter, ensuring the rod passes through the pipe with extremely high straightness and allowing for more precise installation at the designed position. This significantly reduces final construction deviations and guarantees project quality.

[0015] Furthermore, by connecting the two positioning discs with elastic elements and using proximal and distal connecting arms to movably connect the support body to the two positioning discs, a clever "tension-expansion" mechanism is formed. When the device is placed in the pipeline and subjected to axial compression or its own gravity, the two positioning discs will overcome the tension of the elastic elements and move away from each other; this movement is converted into radial outward displacement of the support body through the connecting arms, forcing the support body to press tightly against the inner wall of the pipeline, improving the installation stability of the pipe support device in the pipeline, and thus enabling more stable and precise high-precision positioning and guidance of the rods. At the same time, this structure allows the same pipe support device to automatically adapt and firmly engage in pipelines with different inner diameters, greatly improving the versatility of the device and the convenience of on-site construction.

[0016] In some embodiments, one end of the proximal connecting arm is rotatably pivoted to the proximal positioning disk, and the other end is rotatably pivoted to the support body. By explicitly employing a "rotatably pivoted" (or hinged) connection, the movable connection is concretized as a revolute joint connection. This connection method transforms the movement between the proximal connecting arm, the proximal positioning disk, and the support body into a relatively pure rotational motion, greatly reducing friction and resistance during movement. This ensures that the support body can move smoothly, flexibly, and precisely under the drive of the elastic element, thereby improving the reliability and responsiveness of the entire device's operation.

[0017] Furthermore, in some embodiments, one end of the distal connecting arm is rotatably pivoted to the distal positioning disk, and the other end is rotatably pivoted to the support body. Similarly, the same pivoting structure is used for the distal connecting arm, so that both ends of the support body are connected to the proximal and distal positioning disks respectively through relatively symmetrical and low-friction rotating pairs. This ensures that the support body experiences balanced forces and a stable motion trajectory during movement, making the entire expansion and contraction process smoother, and further enhancing the structural stability and operational consistency of the device.

[0018] In some embodiments, the support includes:

[0019] A connecting rod, one end of which is connected to the proximal connecting arm and the other end of which is connected to the distal connecting arm;

[0020] The adapter sleeve, used to abut against the inner wall of the pipe, is configured to be rotatably fitted onto the connecting rod.

[0021] The support body is designed as a split unit consisting of a connecting rod and an adapter sleeve, with the adapter sleeve capable of rotating around the connecting rod. This improvement transforms the sliding friction between the support body and the inner wall of the pipe into rolling friction. This significantly reduces friction, making the insertion, adjustment, and removal of the device within the pipe easier and smoother; it also reduces wear, extending the device's lifespan and protecting the inner wall of the pipe.

[0022] Furthermore, in some embodiments, the extension direction of the rotation axis of the adapter sleeve is configured to align with the extension direction of the axis of the insertion channel. The rolling direction of the adapter sleeve is perfectly aligned with the primary direction of movement of the device (i.e., insertion and removal into the pipe along the pipe axis). This allows the adapter sleeve to achieve optimal rolling performance during axial movement of the device, minimizing axial frictional resistance.

[0023] In some embodiments, multiple elastic elements are arranged at intervals around the insertion channel. This arrangement of multiple elastic elements around the insertion channel provides a symmetrical and uniform elastic restoring force that brings the two positioning discs together. This ensures that the two positioning discs remain parallel during movement, thereby causing all supports to expand outward or contract inward synchronously and consistently, greatly improving the support stability of the device.

[0024] Furthermore, in some embodiments, several elastic elements are configured to be evenly distributed around the insertion channel. The definition of "evenly distributed" ensures a symmetrical distribution of the circumferential mechanical properties of the entire device, mitigates the adverse effects of non-uniform forces, and optimizes the support effect of the device.

[0025] Furthermore, in some embodiments, the support and elastic element are arranged alternately in the circumferential direction of the insertion channel. This "alternating arrangement" optimizes the spatial configuration of the elastic element and the support transmission element in the circumferential direction. This layout is compact, has a reasonable force distribution, reduces interference between mechanisms, makes full use of circumferential space, and makes the overall structure more scientific, balanced, and reliable.

[0026] Furthermore, in some embodiments, one end of the elastic element is configured to be detachably connected to the proximal positioning plate, and the other end of the elastic element is configured to be detachably connected to the distal positioning plate. The limitation of "detachable connection" (e.g., hook, screw, etc.) makes the elastic element a modular component that can be quickly replaced. This facilitates the maintenance of the elastic element, extends the service life of the entire device, and reduces the user's long-term operating costs.

[0027] In some embodiments, a plurality of supports are configured to be evenly distributed around the insertion channel. This even distribution of supports means that the supporting force on the rod and the inner wall of the pipe is circumferentially uniform, resulting in more uniform contact stress between the device and the inner wall of the pipe, thereby achieving better concentricity support and higher positioning accuracy.

[0028] The main beneficial effects of the above technical solution are as follows:

[0029] This solution provides an internal pipe support device that can be snapped into a pipe. The insertion channel formed by the interlocking of the proximal and distal positioning discs provides a positioning reference for the insertion and guidance of the rod inside the pipe, improving the positioning accuracy of the rod. At the same time, the radial expansion of the support body is driven by the elastic element, so that the same device can automatically adapt to and be firmly snapped into pipes of different diameters, realizing universal internal pipe support.

[0035] The present invention will be specifically illustrated below with reference to embodiments:

[0036] Example:

[0037] Pipe support devices are used to position and support rods inserted into pipes; for example, attachments. Figure 3 and attached Figure 4 As shown, a rod B needs to be inserted into the channel A1 of the positioning pipe A. The internal support device is used to lock into the channel A1 to position and support the rod B.

[0038] For details, see attached. Figure 1 To be continued Figure 2 As shown, the tube support device in this embodiment includes: a proximal positioning disk 1, a distal positioning disk 2, an elastic element 3, and a support body 4.

[0039] The proximal positioning disk 1 has a proximal positioning hole 1.1 for inserting rod B; the distal positioning disk 2 has a distal positioning hole 2.1 for inserting rod B; the proximal positioning disk 1 and the distal positioning disk 2 are arranged at intervals, and the proximal positioning hole 1.1 and the distal positioning hole 2.1 are aligned so that the proximal positioning hole 1.1, the distal positioning hole 2.1, and the space between the proximal positioning hole 1.1 and the distal positioning hole 2.1 together form an insertion channel for inserting and positioning the rod. The axis of this insertion channel is shown in the attached figure. Figure 2 As shown by the central axis X.

[0040] The elastic element 3 is a component that is elastic and can be stretched under force to undergo elastic deformation, such as a spring; one end of the elastic element 3 is connected to the proximal positioning disk 1 and the other end is connected to the distal positioning disk 2.

[0041] In this embodiment, multiple elastic elements 3 can be arranged, with the multiple elastic elements 3 spaced apart around the insertion channel. Preferably, the multiple elastic elements 3 can also be evenly arranged around the insertion channel; for example, one elastic element 3 is provided at every 90 degrees along the circumference of the insertion channel.

[0042] One end of the elastic element 3 can be detachably connected to the proximal positioning plate 1 by means of, for example, a screw or a hook structure, and the other end of the elastic element 3 can also be detachably connected to the distal positioning plate 2 by means of, for example, a screw or a hook structure, so that the elastic element 3 can be disassembled.

[0043] Support 4 is used to abut against the inner wall of the pipe. Several supports 4 are distributed at intervals around the insertion hole so that they can be locked together in the positioning pipe A.

[0044] For each support body 4, one end is movably connected to the proximal positioning plate 1 via the proximal connecting arm 5, and the other end is movably connected to the distal positioning plate 2 via the distal connecting arm 6, so that the support body 4 can be moved closer to the insertion channel by separating and moving the two positioning plates, so that several support bodies 4 together form a snap-fit ​​structure that can be positioned and snapped into pipes of different diameters.

[0045] For example, in this embodiment, one end of the proximal connecting arm 5 is rotatably pivotally connected to the proximal positioning disk 1 (i.e., for two components, these two components are connected together by a common shaft (or pin) so that they can rotate relative to each other about this shaft), the pivotally connected rotation shaft 5a is as shown in the attached figure. Figure 2 As shown; when axis X extends horizontally to the left and right, the rotating shaft 5a extends horizontally to the front and back, perpendicular to axis X. The other end of the proximal connecting arm 5 is rotatably pivotally connected to the support body 4, and the pivotally connected rotating shaft 5b is shown in the attached figure. Figure 2 As shown, when axis X extends horizontally to the left and right, the rotating shaft 5b extends horizontally to the front and back to be perpendicular to axis X.

[0046] Similarly, one end of the distal connecting arm 6 can also be rotatably pivoted to the distal positioning disk 2, and the pivoting rotation shaft 6a is shown in the attached figure. Figure 2 As shown; when axis X extends horizontally to the left and right, the rotating shaft 6a extends horizontally to the front and back, perpendicular to axis X. The other end of the distal connecting arm 6 is rotatably pivotally connected to the support 4, and the pivotally connected rotating shaft 6b is shown in the attached figure. Figure 2 As shown, when axis X extends horizontally to the left and right, the rotating shaft 6b extends horizontally to the front and back to be perpendicular to axis X.

[0047] As attached Figure 2 As shown, the support body 4 in this embodiment includes a connecting rod 4.1 and an adapter sleeve 4.2.

[0048] Specifically, the connecting rod 4.1 is a long shaft, one end of which is rotatably pivoted to the proximal connecting arm 5, and the other end is rotatably pivoted to the distal connecting arm 6.

[0049] The adapter sleeve 4.2 is a component used for abutting and positioning against the inner wall of the pipe. The adapter sleeve 4.2 is configured to be rotatably fitted onto the connecting rod 4.1. For example, a bearing is fitted onto the connecting rod 4.1, with its inner ring fixed to the connecting rod 4.1 and its outer ring forming the adapter sleeve 4.2, which can rotate and is used to abut against the inner wall of the pipe.

[0050] As attached Figure 3As shown, the extension direction of the rotation axis of the adapter sleeve 4.2 is configured to conform to the extension direction of the axis of the insertion channel. This conformity means that the extension direction of the rotation axis of the adapter sleeve 4.2 is preferably parallel to the extension direction of the axis of the insertion channel, but misalignment that does not affect movement is permissible. For example, when axis X extends horizontally to the left and right, the rotation axis of the adapter sleeve 4.2 also extends horizontally to the left and right.

[0051] In this embodiment, the support body 4 and the elastic element 3 can be arranged alternately in the circumferential direction of the insertion channel; that is, an elastic element 3 is provided between any two support bodies 4 in the circumferential direction of the insertion channel.

[0052] Furthermore, several supports 4 can be evenly arranged around the insertion channel in the circumference of the insertion channel, with one support 4 provided at every 90 degrees.

[0053] When using the internal support device:

[0054] First, determine the outer diameter of the channel A1 of the positioning pipe A, and then apply force to the near-end positioning plate 1 and the far-end positioning plate 2 to drive the near-end positioning plate 1 and the far-end positioning plate 2 away from each other.

[0055] At this time, the elastic element 3 is stretched and deformed, and the proximal connecting arm 5 and the distal connecting arm 6 move closer to the insertion channel, thereby driving several supports 4 to move synchronously closer to the insertion channel, reducing the outer diameter d of the tube support device (as shown in the attached figure). Figure 3 (As shown).

[0056] When the outer diameter d is smaller than the outer diameter of the channel A1, the internal support device can be placed in the channel A1; at this time, the axis X of the insertion channel and the axis of the channel A1 are often collinear.

[0057] After the pipe support device is placed in the designated position, the external force is released, and the elastic element 3 elastically recovers, thereby pulling the proximal positioning plate 1 and the distal positioning plate 2 closer to each other. This, in turn, drives the proximal connecting arm 5 and the distal connecting arm 6 to move closer to the inner wall of the channel A1, thereby driving several support bodies 4 to move outward synchronously and abut against the inner wall of the channel A1, thus realizing the installation and positioning of the pipe support device in the channel A1.

[0058] After the installation and positioning of the internal support device are completed, rod B is inserted into the insertion channel formed by the near-end positioning hole 1.1, the far-end positioning hole 2.1, and the space between the near-end positioning hole 1.1 and the far-end positioning hole 2.1, so as to achieve positioning support for rod B.
