The connecting plate 13 has a clearance fit or a transition fit with the rotating shaft 2. The first and second internally toothed plates 12, 14 are symmetrically arranged on the left and right sides of the connecting plate 13.

[0039] In this embodiment, an arc-shaped notch 16 is provided in the upper end of the first inner tooth plate 12, and a plurality of inner teeth 15 are evenly spaced along the circumference of the arc-shaped notch 16, and a plurality of inner teeth 15 are also evenly spaced along the circumference of the rotating shaft 2.

The lower end of the first inner tooth plate 12 is connected and fixed to the base plate 11.

[0040] In this embodiment, the upper end of the connecting plate 13 is provided with an arc-shaped outer convex surface 17, and one end of the rotating arm 3 contains an arc-shaped inner convex surface 34. The diameter of the arc-shaped outer convex surface 17 is the same as the diameter of the arc-shaped inner convex surface 34. The center of the arc-shaped outer convex surface 17 and the center of the arc-shaped inner convex surface 34 are both located on the axis of the rotating shaft 2. Along the axial direction of the rotating shaft 2, the arc-shaped inner convex surface 34 is located between the first outer tooth plate 32 and the second outer tooth plate 33. The arc-shaped inner convex surface 34 matches and fits with the arc-shaped outer convex surface 17. Figures 1 to 5 shown.

[0041] In this embodiment, the first outer tooth plate 32 and the second outer tooth plate 33 are parallel to each other, the first outer tooth plate 32 and the second outer tooth plate 33 are symmetrical and mirror images of each other, the axis of the rotating shaft 2 is perpendicular to the first outer tooth plate 32 and the second outer tooth plate 33, the rotating shaft 2 and the first outer tooth plate 32 have a clearance fit or a transition fit, and the rotating shaft 2 and the second outer tooth plate 33 have a clearance fit or a transition fit.

[0042] In this embodiment, the rotating arm 3 includes a rotating arm rod 31, which is perpendicular to the rotating shaft 2. Along the extension direction of the rotating arm rod 31, the first external tooth plate 32 includes an annular segment 36 and a connecting segment 37 arranged in sequence. The annular segment 36 is connected and fixed to one end of the rotating arm rod 31 through the connecting segment 37. Multiple external teeth 35 are located on the edge of the annular segment 36. The multiple external teeth 35 are evenly spaced along the circumference of the annular segment 36, and the multiple external teeth 35 are also evenly spaced along the circumference of the rotating shaft 2. The rotating shaft 2 passes through the annular segment 36 of the first external tooth plate 32.

[0043] The rotating shaft 2 has a clearance fit or transition fit with the annular segment 36 of the first outer toothed plate 32, and the rotating shaft 2 has a clearance fit or transition fit with the annular segment 36 of the second outer toothed plate 33. Along the axis of the rotating shaft 2, the distance between the first outer toothed plate 32 and the second outer toothed plate 33 is equal to the distance between the first inner toothed plate 12 and the second inner toothed plate 14. The thickness of the first outer toothed plate 32 is less than or equal to (preferably equal to) the thickness of the first inner toothed plate 12.

[0044] In this embodiment, the rotating shaft 2 and the baffle 4 can be connected by threading, screwing or clamping. A circular end plate 21 is provided at the left end of the rotating shaft 2. The end plate 21 is stacked and connected with the first outer tooth plate 32. The outer diameter of the end plate 21 is larger than the diameter of the root circle 151 of the inner teeth 15 of the first inner tooth plate 12. The circular baffle 4 is stacked and connected with the second outer tooth plate 33. The outer diameter of the baffle 4 is larger than the diameter of the root circle 151 of the inner teeth 15 of the second inner tooth plate 14. Along the axial direction of the rotating shaft 2, the end plate 21, the first outer tooth plate 32, the connecting plate 13, the second outer tooth plate 33 and the baffle 4 are arranged in sequence, as shown in FIG. Figures 1 to 5 shown.

[0045] The working process of the angle-adjustable pipeline support (also known as the angle-adjustable pipeline support for integrated pipeline corridor) is introduced below.

[0046] Bolts pass through the first mounting holes 111 on the bottom plate 11 to connect and fix the base 1 to the integrated pipe gallery 5, and the rotating shaft 2 and the baffle 4 can be connected by threads. The rotating shaft 2 passes through the first outer tooth plate 32, the connecting plate 13, and the second outer tooth plate 33 in sequence. The rotating arm 3 rotates around the rotating shaft 2 to the required angle. The inner teeth 15 of the first inner tooth plate 12 are matched and meshed with the outer teeth 35 of the first outer tooth plate 32. The inner teeth 15 of the second inner tooth plate 14 are matched and meshed with the outer teeth 35 of the second outer tooth plate 33. The baffle 4 is tightened, and the distance between the baffle 4 and the end plate 21 gradually decreases until the end plate 21 is tightly stacked with the first outer tooth plate 32 and the baffle 4 is tightly stacked with the second outer tooth plate 33. At this time, the pipeline support capable of adjusting the angle is in a locked state, and the rotating arm 3 cannot rotate around the rotating shaft 2. Figure 6 and Figure 8 shown.

[0047] When the angle needs to be adjusted, unscrew the baffle 4 (i.e., loosen the baffle 4), and the distance between the baffle 4 and the end plate 21 gradually increases until the distance between the baffle 4 and the second outer tooth plate 33 is greater than or equal to the thickness of the second outer tooth plate 33. The rotating arm 3 moves to the right along the axial direction of the rotating shaft 2 relative to the base 1, and the distance moved by the rotating arm 3 is equal to the thickness of the second outer tooth plate 33. At this time, the pipeline support capable of adjusting the angle is in an unlocked state.

[0048] Then, rotate the rotating arm 3 around the rotating shaft 2 by a set angle, which is an integer multiple of the central angle corresponding to the internal teeth 15. After the rotating arm 3 rotates around the rotating shaft 2 by the set angle, the rotating arm 3 moves leftward along the axial direction of the rotating shaft 2 relative to the base 1, and the internal teeth 15 of the first internal tooth plate 12 are re-matched and connected with the external teeth 35 of the first external tooth plate 32, and the internal teeth 15 of the second internal tooth plate 14 are re-matched and connected with the external teeth 35 of the second external tooth plate 33. Tighten the baffle 4 to make the angle-adjustable pipeline support return to the locked state again, as Figure 7 shown.

[0049] The rotating arm of the angle-adjustable pipeline support can not only adjust the angle, but also be convenient for disassembly and assembly, which is beneficial to accurately lay cables in the utility tunnel and improve the construction efficiency, and is especially suitable for the utility tunnel with an arc-shaped inner surface. The rotating arm of the angle-adjustable pipeline support has the advantages of uniformly adjustable angle, easy installation, stable quality and cost saving.

[0050] Embodiment 2

[0051] This embodiment is an improvement on Embodiment 1. The difference between this embodiment and Embodiment 1 is that:

[0052] The swing arm rod 31 has a wavy structure, the swing arm rod 31 has wave crests and wave troughs, the other end of the swing arm rod 31 is provided with an upward bending part 38, and the swing arm rod 31 is provided with a second mounting through hole 311, and the axis of the second mounting through hole 311 is perpendicular to the axis of the rotating shaft 2. During use, the cable can be fixed at the wave trough of the wavy structure, and the second mounting through hole 311 can be used to install screws to fix the cable by means of clamping. Or, after connecting the cable with a binding rope, the binding rope passes through the second mounting through hole 311 to achieve the connection and fixation of the cable, as Figure 9 shown.

[0053] The remaining technologies in this embodiment are the same as those in Embodiment 1. For the sake of saving space, this embodiment will not be introduced in detail.
