[0052] The pipeline fixing device 100 according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0053] like Figures 1 to 6 As shown, the pipeline fixing device 100 according to an embodiment of the present invention is used to fix the pipeline 300 in a chamber or tunnel. The pipeline fixing device 100 includes an anchor rod 10 and a rigid hanging member.

[0054] Specifically, one end of the anchor rod 10 is inserted into the chamber or tunnel wall 200, and the other end of the anchor rod 10 extends out of the chamber or tunnel wall 200; the rigid lifting component is arranged on the other end of the anchor rod 10 extending out of the chamber or tunnel wall 200 and is connected to the other end of the anchor rod 10, and the rigid lifting component is provided with an installation structure for installing the pipeline 300 in the chamber or tunnel.

[0055] According to the pipeline fixing device 100 of the embodiment of the present invention, the pipeline 300 is installed in the chamber or tunnel through the anchor rod 10 and the rigid lifting parts, combining the advantages of the anchor rod 10 and the rigid lifting parts. It is not only simple to process, easy to install, and has low working intensity, but also easy to maintain and has good applicability. It is especially suitable for the installation of pipelines in underground projects with poor working environment and difficult operations.

[0056] According to one embodiment of the present invention, the anchor rod 10 is inserted into the side wall 200 of the chamber or tunnel and extends roughly in the horizontal direction. The mounting structure 20a is roughly formed in an L shape. The mounting structure 20a includes a first rod body 21 and a second rod body 22. One end of the first rod body 21 is connected to the other end of the anchor rod 10, and one end of the second rod body 22 is connected to the other end of the first rod body 21. The first rod body 21, the second rod body 22 and the chamber or tunnel wall 200 cooperate to define an installation groove, and the pipeline is installed in the installation groove.

[0057] Optionally, the mounting structure 20a is integrally formed with the rigid hanging component.

[0058] Specifically, Figure 1 As shown, the second rod body 22 can be formed into a hook shape, and the hook-shaped second rod body 22 limits the outer side of the pipeline 300 located in the installation groove, and the chamber or tunnel wall 200 limits the inner side of the pipeline 300, so that the second rod body 22 and the chamber or tunnel wall 200 cooperate to install and fix the pipeline 300, and the stability is better. The one-piece mounting structure 20a is simple to manufacture, occupies a small space after installation, and has a good use effect.

[0059] According to one embodiment of the present invention, the other end of the anchor rod 10 is provided with a first connecting portion 40, and the mounting structure 20b includes a body 23 and at least one first hook 24. One end of the body 23 is connected to the first connecting portion 40; at least one first hook 24 is connected to the body 23, and at least one first hook 24 is provided with a first receiving groove for installing a pipeline.

[0060] Specifically, the first connection portion 40 is substantially formed in a ring shape and is provided at the other end of the anchor rod 10 , and the body 23 is formed in a rod shape, and one end of the body 23 is movably connected to the first connection portion 40 .

[0061] Therefore, the rod-shaped main body 23 can further adapt to different installation environments, especially in underground projects with uneven outer contours. The installation structure 20b including the main body 23 and the first hook 24 not only ensures the anchoring length of the anchor rod 10, but also simplifies the operation procedure, shortens the operation time, and overcomes the problem of difficult installation accuracy control in underground projects.

[0062] Optionally, according to another embodiment of the present invention, there are a plurality of first hooks 24 , and the plurality of first hooks 24 are arranged at intervals along the axial direction of the body 23 .

[0063] Specifically, for example, two first hooks 24 may be arranged at intervals in the axial direction of the body 23, such as Figure 2aAs shown, the anchor rod 10 can be inserted into the chamber or tunnel side wall 200 in a roughly horizontal direction. At this time, the rigid hanging member is roughly perpendicular to the axis of the anchor rod 10 and is in a suspended state. The two first hooks 24 are provided with two first receiving grooves to increase the loading capacity of the pipeline fixing device 100. At this time, the installation structure 20b can be such a structure: the body 23 and the first hook 24 located at the end of the body 23 are integrally formed, and the other first hook 24 is connected to the body 23 by welding. Figure 2b As shown, the anchor rod 10 can also be inserted into the top wall 200 of the chamber or tunnel roughly in the vertical direction, and at this time, the axis of the rigid hanging piece and the anchor rod 10 are roughly in a straight line. Therefore, in underground projects with uneven outer contours, there is no need to adjust the length of the anchor rod 10 on site. The length of the anchor rod 10 can be compensated by adjusting the connection position of the rigid hanging piece, thereby ensuring the anchoring length of the anchor rod 10.

[0064] According to another embodiment of the present invention, the mounting structure 20 b further includes a first flexible hanging member 50 . One end of the first flexible hanging member 50 is connected to the first connecting portion 40 , and the other end of the first flexible hanging member 50 is connected to one end of the body 23 .

[0065] Specifically, the first flexible hanging member 50 includes a plurality of interlocking hanging rings or is formed into a flexible hanging rope. In addition, the first flexible hanging member 50 can also be other forms well known to those skilled in the art.

[0066] It should be noted that if Figure 3a As shown, the anchor rod 10 can be inserted into the chamber or tunnel side wall 200 in a substantially horizontal direction, and the rigid hanging member and the first flexible hanging member 50 are substantially perpendicular to the axis of the anchor rod 10, as shown in FIG. Figure 3b As shown, the anchor rod 10 can also be inserted into the top wall 200 of the chamber or tunnel roughly in the vertical direction. At this time, the rigid hanging member and the first flexible hanging member 50 are roughly in a straight line with the axis of the anchor rod 10.

[0067] Therefore, the length of the anchor rod 10 can be adjusted by adjusting the connection position between the first flexible hanging member 50 and the body 23, or by adjusting the length of the first flexible hanging member 50, so as to adapt to different working environments, which is flexible and convenient.

[0068] According to another embodiment of the present invention, the anchor rod 10 is inserted into the chamber or tunnel top wall 200 and extends roughly in the vertical direction. The lower end of the anchor rod 10 extends out of the chamber or tunnel top wall 200. The mounting structure 20c is formed as a second hook arranged at the lower end of the anchor rod 10. One end of the second hook is connected to the lower end of the anchor rod 10. The second hook is provided with a second accommodating groove for installing the pipeline.

[0069] Specifically, Figure 4As shown, there are two second hooks, which are respectively arranged on opposite sides of the lower end of the anchor rod 10. Figure 4 As shown, the mounting structure 20c can be manufactured in such a way that one of the second hooks is integrally formed with the anchor rod 10, the other second hook is welded to the anchor rod 10, and the two second hooks are arranged opposite to each other. The two second receiving grooves can increase the loading capacity of the pipeline fixing device 100 and are convenient to use.

[0070] According to one embodiment of the present invention, there are multiple anchor rods 10, and two adjacent anchor rods 10 are combined into a group. Each anchor rod 10 is respectively inserted into the top wall 200 of the chamber or tunnel and extends roughly in the vertical direction. The lower end of the anchor rod 10 extends out of the top wall 200 of the chamber or tunnel. The mounting structure 20d is formed as a third hook 25 arranged at the lower end of the anchor rod 10. The third hook 25 is roughly formed in a U shape. The two legs of the third hook 25 are respectively connected to the lower ends of the two adjacent anchor rods 10, and the pipeline is installed in the third hook 25.

[0071] Optionally, according to one embodiment of the present invention, both ends of the third hook 25 are connected to the anchor rod 10 by bolts 60 .

[0072] Specifically, Figure 5 As shown, the lower part of the U-shaped third hook 25 can be installed with the pipeline 300. The two ends of the third hook 25 can be fixed to the anchor rod 10 by bolts 60, nuts 70 and pads 80. This fixing method is detachable and simple and reliable.

[0073] According to one embodiment of the present invention, a second connecting portion 90 is provided at the lower end of the anchor rod 10, and the second connecting portion 90 is roughly formed in a ring shape. The mounting structure 20d also includes a second flexible hanging member 26, the upper end of the second flexible hanging member 26 is connected to the second connecting portion 90, and the lower end of the second flexible hanging member 26 is connected to the third hook 25.

[0074] Specifically, the second flexible hanging member 26 includes a plurality of interlocking hanging rings or is formed as a flexible hanging rope.

[0075] Therefore, if Figure 6 As shown, the two ends of the U-shaped third hook 25 are respectively connected to a second flexible hanging member 26. By adjusting the length of the second flexible hanging member 26, or adjusting the connection position between the second flexible hanging member 26 and the anchor rod 10, the length of the pipeline fixing device 100 can be adjusted, thereby eliminating the need to adjust the length of the anchor rod 10 on site, thereby ensuring the anchoring length of the anchor rod 10.

[0076] According to one embodiment of the present invention, at least one section of the anchor rod 10 extending into the chamber or tunnel wall 200 forms a twist structure 30. The anchor rod 10 with the twist structure 30 has a stronger anchoring force and can improve the stability of the anchor rod 10.

[0077] According to one embodiment of the present invention, a portion of the anchor rod 10 extending into the chamber or tunnel wall 200 is fixed by an anchoring agent.

[0078] Specifically, the anchoring agent includes but is not limited to cement mortar. If cement mortar is used as the anchoring agent, the anchor rod 10 may not be provided with the above-mentioned twist structure 30.

[0079] The comparison results of the advantages and disadvantages of the pipeline fixing device 100 (recorded as a rigid hanging piece type) according to the embodiment of the present invention and the gourd-type pipeline fixing device and the bracket-type pipeline fixing device (respectively recorded as gourd-type and bracket-type) in the prior art are shown in Table 1: Results of different pipeline fixing devices.
