Description

Technical Field

[0001] The utility model relates to a pipeline installation structure for a shallow fragile zone maintenance tunnel, belonging to the technical field of water conservancy tunnel construction. Background Art

[0002] During the construction of maintenance tunnels in shallow fragile zones, in order to ensure the power and water supply to the working surface in the tunnel, brackets need to be installed on the side walls of the tunnel to support the laying of cables and water pipes.

[0003] The existing bracket support pipeline technology, see Chinese patent publication number CN219953441U, the pipeline is laid on the bracket's drag plate to obtain support. However, when the pipeline needs to be pulled and displaced, there is a problem that the displaced pipeline and the bracket generate static friction and are prone to damage. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a pipeline installation structure for shallow fragile maintenance tunnels.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a pipeline installation structure for a shallow fragile maintenance tunnel, comprising:

[0007] water pipeline tunnels;

[0008] Bracket fixed on the side wall of the water pipeline tunnel;

[0009] There are rollers on the bracket that can rotate and roll, and the rollers can provide rolling for pulling the pipeline.

[0010] The bracket comprises a vertical section, a horizontal section and an oblique support section; the oblique support section is fixedly installed between the vertical section and the horizontal section.

[0011] The horizontal section is a square tube. The square tube sleeve is inserted into the outer surface of the horizontal section. After the square tube sleeve is matched with the horizontal section, it can only slide but cannot rotate.

[0012] A rotatable roller is installed on the top of the square tube sleeve.

[0013] A rotating shaft is provided inside the roller, and both ends of the rotating shaft can be rotatably mounted on two roller seats distributed at intervals; the two roller seats distributed at intervals are fixed to the square tube sleeve.

[0014] A receiving plate is fixedly connected to the roller seat close to the side wall of the water pipeline tunnel. The receiving plate is made of an elastic steel plate and can undergo elastic deformation. The receiving plate is fixedly connected to the horizontal section through an elastic rubber block. A friction convex portion is integrally fixed to the bottom surface of the middle part of the receiving plate. A friction concave portion is provided on the horizontal section to correspond to the friction convex portion. After the pipeline is placed in the middle of the receiving plate, the middle part of the receiving plate is pressed down and elastically deformed, so that the friction convex portion on the bottom surface of the middle part of the receiving plate corresponds to the friction concave portion of the horizontal section to produce friction limiting. After the square pipe sleeve is matched with the horizontal section, its sliding is restricted.

[0015] The beneficial effect of the utility model is that the pipeline to be pulled and extended is placed on the rotatable roller on the square tube sleeve. When the pipeline is pulled, the roller rotates on the square tube sleeve, avoiding the static friction between the pipeline and the bracket, which is prone to damage. This solves the problem that the pipeline that needs to be pulled and extended will cause displacement and will cause static friction with the bracket, which is prone to damage.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0020] like Figures 1 to 2 shown.

[0021] The present application provides a pipeline installation structure for a shallow fragile maintenance tunnel, comprising:

[0022] A water pipeline tunnel 1 is excavated to the designed size without any decorative construction. A bracket 2 is fixed to the side wall of the water pipeline tunnel 1 by bolts. The vertical section 21 of the bracket 2 is fixed to the side wall of the water pipeline tunnel 1 by bolts. A diagonal bracing section 23 is installed between the vertical section 21 and the horizontal section 22 of the bracket 2.

[0023] The horizontal section 22 of the bracket 2 is a square tube. The square tube sleeve 31 is inserted into the outer surface of the horizontal section 22. After the square tube sleeve 31 is matched with the horizontal section 22, it can only slide but not rotate.

[0024] A rotatable roller 32 is mounted on top of the square tube sleeve 31. A rotating shaft 41 is located within the roller 32. The ends of the rotating shaft 41 are rotatably mounted on two spaced roller seats 42. The two spaced roller seats 42 are welded or integrally formed with the square tube sleeve 31. The roller 32 is made of hard rubber; the rotating shaft 41 and roller seats 42 are made of metal.

[0025] When the pipeline 61 needs to be pulled and extended, the pipeline 61 to be pulled and extended is placed on the rotatable roller 32 on the square tube sleeve 31. When the pipeline 61 is pulled, the roller 32 rotates on the square tube sleeve 31. The rolling roller 32 provides rolling for the pipeline 61, avoiding the situation where the pipeline 61 and the bracket 2 generate static friction and are prone to damage, thereby solving the problem that the pipeline needs to be pulled and extended and causes displacement, which will generate static friction with the bracket and be prone to damage.

[0026] A receiving plate 51 is welded and fixedly connected to the roller seat 42 close to the side wall of the water pipeline tunnel 1. The receiving plate 51 is made of an elastic steel plate and can undergo elastic deformation. The receiving plate 51 is fixedly connected to the horizontal section 22 through an elastic rubber block 53. The elastic rubber block 53 provides an upward elastic force to reset the receiving plate 51 upward. A friction convex portion 52 is integrally fixed to the bottom surface of the middle part of the receiving plate 51. A friction concave portion is provided on the horizontal section 22 to correspond to the friction convex portion 52. After the pipeline 61 is placed in the middle of the receiving plate 51, the middle part of the receiving plate 51 is pressed down and elastically deformed, so that the friction convex portion 52 on the bottom surface of the middle part of the receiving plate 51 corresponds to the friction concave portion of the horizontal section 22 to produce friction limit. At this time, the sliding of the square tube sleeve 31 is restricted after cooperating with the horizontal section 22.
