[0031] The utility model will be further described below in conjunction with the accompanying drawings.

[0032] It should be noted that the pipeline to be transported in the present application is a long-distance pipeline for tunnel construction, and the tunnel roller support in the present application is used for the transportation of the long-distance pipeline in the tunnel. Of course, the tunnel roller support in the present application is not limited to the transportation of long-distance pipelines, but can also be used for the transportation of other pipelines, such as drainage pipes for construction or oil casing for drilling.

[0033] like Figure 1 As shown, the utility model provides a roller support for a tunnel, which includes a first roller frame assembly 10, a second roller frame assembly 20 and a connecting assembly 30. The second roller frame assembly 20 is spaced apart from the first roller frame assembly 10 in the first direction; one end of the connecting assembly 30 is connected to the first roller frame assembly 10, and the other end of the connecting assembly 30 is connected to the second roller frame assembly 20; the first roller frame assembly 10 includes a first rolling body 13, and the second roller frame assembly 20 includes a second rolling body 21. The first rolling body 13 and the second rolling body 21 can simultaneously support the pipeline to be transported, and can roll on the outer wall surface of the pipeline to be transported.

[0034] In the above arrangement, the first roller frame assembly 10 and the second roller frame assembly 20 are provided, and the first rolling body 13 of the first roller frame assembly 10 and the second rolling body 21 of the second roller frame assembly 20 are used to simultaneously support the pipeline to be transported. This improves the support stability of the tunnel roller support for the pipeline to be transported. Moreover, the first rolling body 13 and the second rolling body 21 can roll on the outer wall surface of the pipeline to be transported. This reduces the friction between the pipeline to be transported and the first rolling body 13 and the second rolling body 21. Thereby, the transportation efficiency of the pipeline to be transported is improved.

[0035] In addition, a connecting assembly 30 is provided in the tunnel roller support, and the first roller support assembly 10 and the second roller support assembly 20 are connected into one body by the connecting assembly 30. Thus, the overall structural strength of the tunnel roller support is improved, thereby ensuring that the tunnel roller support can stably support the pipeline to be transported.

[0036] Specifically, Figure 1 As shown, in one embodiment, the first roller frame assembly 10 further includes a first base 11 and a first support frame 12. The first support frame 12 is disposed on the first base 11, and the first rolling body 13 is rotatably disposed on the first support frame 12. In this way, the first rolling body 13 is in rolling contact with the pipe to be transported, thereby reducing the friction between the first rolling body 13 and the pipe to be transported, thereby improving the transportation efficiency of the pipe to be transported.

[0037] Specifically, Figure 1 As shown, in one embodiment, the first base 11 includes a first I-beam 111 and a second I-beam 112. The second I-beam 112 is connected to one side of the first I-beam 111; the top ends of the first I-beam 111 and the second I-beam 112 are flush, and the first support frame 12 is arranged at the top ends of the first I-beam 111 and the second I-beam 112.

[0038] Specifically, in one embodiment, the first I-beam 111 and the second I-beam 112 are connected by welding.

[0039] Specifically, Figure 1 As shown, in one embodiment, the first base 11 further includes a reinforcing rib plate 113, which is disposed between two flange plates of the first I-beam 111 and connected to the web of the first I-beam 111. Thus, the overall structural strength of the first base 11 is improved.

[0040] Specifically, Figure 1 As shown, in one embodiment, the stiffener plate 113 is disposed between two flange plates of the second I-beam 112 and connected to the web plate of the second I-beam 112 .

[0041] Specifically, Figure 1 As shown, in one embodiment, there are multiple reinforcing rib plates 113, and the multiple reinforcing rib plates 113 are arranged at intervals.

[0042] Specifically, Figure 1As shown, in one embodiment, the first support frame 12 includes two first roller frames 121 arranged opposite to each other in the second direction, and the first rolling body 13 includes two first rollers 131 arranged opposite to each other in the second direction. The two first rollers 131 are rotatably arranged on the two first roller frames 121. The two first rollers 131 can simultaneously support the pipeline to be transported and roll on the outer wall surface of the pipeline to be transported. This improves the support stability of the tunnel roller support for the pipeline to be transported.

[0043] Specifically, Figure 1 As shown, in one embodiment, two first rollers 131 are symmetrically arranged along the central axis D of the first base 11. In this way, the pipeline to be transported is evenly stressed when sliding on the first rolling body 13, thereby further improving the support stability of the tunnel roller support for the pipeline to be transported. Specifically, as Figure 1 As shown, in one embodiment, the two first rollers 131 are respectively arranged at a certain angle to the first base 11, wherein one of the two first rollers 131 has an angle β with the top end of the first base 11, and the value range of the angle β is: 30°≤angle β≤45°, and the other first roller 131 has an angle γ with the top end of the first base 11, and the value range of the angle β is: 30°≤angle γ≤45°.

[0044] Specifically, Figure 1 As shown, in one embodiment, the value of the angle β is 45°, and the value of the angle γ is 45°.

[0045] It should be noted that the two first rollers 131 are configured in an inverted "eight" structure, which can prevent the pipeline to be transported from escaping from the first rolling body 13. This ensures that the pipeline to be transported can slide normally on the tunnel roller bracket.

[0046] Specifically, Figure 1 As shown, in one embodiment, the outer circumference of the first roller 131 is an inner concave surface, which is concave toward the central axis of the first roller 131, and the outer circumference of the first roller 131 is adapted to the outer circumference of the pipeline to be transported.

[0047] Specifically, Figure 1 As shown, in one embodiment, the first roller 131 includes a body and a rubber layer disposed on the outer peripheral surface of the body, and the outer peripheral surface of the rubber layer is the outer peripheral surface of the first roller 131. In this way, the rubber layer is in direct contact with the anti-corrosion layer on the outer periphery of the pipeline to be transported, and the curvature of the outer peripheral surface of the rubber layer is equal to the curvature of the outer diameter of the pipe. This ensures that the anti-corrosion layer of the pipeline to be transported is not damaged during transportation.

[0048] Specifically, Figure 1As shown, in one embodiment, the connection assembly 30 includes a connection plate 31 and a fixing bolt 32. One end of the connection plate 31 is connected to the first roller frame assembly 10 through the fixing bolt 32, and the other end of the connection plate 31 is connected to the second roller frame assembly 20 through the fixing bolt 32.

[0049] Specifically, Figure 1 As shown, in one embodiment, the first roller frame assembly 10 has the same structure as the second roller frame assembly 20. In this way, the first roller frame assembly 10 and the second roller frame assembly 20 are compatible with each other, thereby improving the manufacturing efficiency of the roller support for the tunnel.

[0050] That is to say, the second roller frame assembly 20 also includes a first base and a first support frame. The first support frame is arranged on the first base, and the first rolling body is rotatably arranged on the first support frame. In this way, the first rolling body rolls in contact with the pipeline to be transported, thereby reducing the friction between the first rolling body and the pipeline to be transported, thereby improving the transportation efficiency of the pipeline to be transported.

[0051] Furthermore, the first base includes a first I-beam and a second I-beam, wherein the second I-beam is connected to one side of the first I-beam; the top ends of the first I-beam and the second I-beam are flush, and the first support frame is arranged at the top ends of the first I-beam and the second I-beam.

[0052] Furthermore, the first I-beam is connected to the second I-beam by welding.

[0053] Furthermore, the first base also includes a reinforcing rib plate, which is arranged between two flange plates of the first I-beam and connected to the web of the first I-beam, thereby improving the overall structural strength of the first base.

[0054] Furthermore, the reinforcing rib plate is arranged between two flange plates of the second I-beam and is connected to the web plate of the second I-beam.

[0055] Furthermore, there are multiple reinforcing rib plates, and the multiple reinforcing rib plates are arranged at intervals.

[0056] Furthermore, the first support frame includes two first roller frames arranged opposite to each other in the second direction, the first rolling body includes two first rollers arranged opposite to each other in the second direction, the two first rollers are rotatably arranged on the two first roller frames, and the two first rollers can simultaneously support the pipeline to be transported and roll on the outer wall surface of the pipeline to be transported, thereby improving the support stability of the tunnel roller support for the pipeline to be transported.

[0057] Furthermore, the two first rollers are symmetrically arranged along the central axis of the first base, so that the pipeline to be transported is evenly stressed when sliding on the first rolling body, thereby further improving the support stability of the tunnel roller support for the pipeline to be transported.

[0058] Furthermore, the two first rollers are respectively arranged at a certain angle to the first base, wherein one of the two first rollers has an angle β with the top end of the first base, and the value range of the angle β is: 30°≤angle β≤45°; the other first roller has an angle γ with the top end of the first base, and the value range of the angle β is: 30°≤angle γ≤45°.

[0059] Furthermore, the value of the angle β is 45°, and the value of the angle γ is 45° (refer to Figure 1 angles indicated in ).

[0060] It should be noted that the two first rollers are configured in an inverted "eight" structure, which can prevent the pipeline to be transported from falling off the first rolling body, thereby ensuring that the pipeline to be transported can slide normally on the tunnel roller bracket.

[0061] Furthermore, the outer circumferential surface of the first roller is an inner concave surface, which is concave toward the central axis of the first roller, and the outer circumferential surface of the first roller is matched with the outer circumferential surface of the pipeline to be transported.

[0062] Furthermore, the first roller includes a body and a rubber layer arranged on the outer peripheral surface of the body, and the outer peripheral surface of the rubber layer is the outer peripheral surface of the first roller. In this way, the rubber layer is in direct contact with the anti-corrosion layer on the outer periphery of the pipeline to be transported, and the curvature of the outer peripheral surface of the rubber layer is equal to the curvature of the outer diameter of the pipe. This ensures that the anti-corrosion layer of the pipeline to be transported is not damaged during transportation.

[0063] It should be noted that the roller support for tunnel in the utility model is welded into a frame structure by H-shaped steel and steel plate, which increases the load bearing capacity and stability. In addition, the first and second rollers are rubber-coated and the curvature is equal to the curvature of the outer diameter of the pipe, so that the pipe (to be transported) protects the anti-corrosion layer of the pipeline during transportation and improves the efficiency of transportation.

[0064] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
