Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline engineering, in particular to a tunnel water supply pipeline supporting device and a using method thereof. BACKGROUND

[0002] Tunnel is a buried engineering building in stratum, which is a form of human utilization of underground space. Tunnel can be divided into traffic tunnel, water tunnel, municipal tunnel, mine tunnel and the like. In order to facilitate water supply and transportation of tunnel, corresponding water supply pipeline is usually laid in tunnel.

[0003] At present, most of water supply pipelines are made of steel material. Due to the reasons such as no sunlight irradiation in tunnel and relatively low air temperature, the tunnel is relatively humid, which causes corrosion and rust of steel water supply pipeline, and further causes damage of steel pipe.

[0004] In order to avoid corrosion and rust of steel pipe, in the prior art, a zinc layer is usually plated on the surface of steel pipe or a zinc block is welded on the surface of steel pipe. Although this kind of way can prevent corrosion and damage of steel pipe, it is inconvenient to supplement zinc after oxidation and consumption of zinc block.

[0005] In addition, during installation of water supply pipeline, it is usually necessary to push and pull the water supply pipeline to adjust the position of water supply pipeline port so as to connect two water supply pipeline ports. However, the traditional water supply pipeline supporting device is not convenient for pushing and pulling movement of pipeline.

[0006] Therefore, the present application provides a water supply pipeline supporting device which is convenient for supplement and replacement of zinc block and convenient for movement and connection of water supply pipeline. SUMMARY

[0007] In order to solve the above problems, the present application provides a tunnel water supply pipeline supporting device and a using method thereof.

[0008] The present application is implemented by the following technical solutions:

[0009] A tunnel water supply pipeline supporting device comprises a lower clamp, an upper clamp and a base. The lower clamp is fixed on the base. The upper clamp is detachably connected with the lower clamp through bolts and nuts. The supporting device further comprises a telescopic elastic force adjusting mechanism, an arc-shaped block, a baffle, a zinc block and a roller plate. The inner walls of the lower clamp and the upper clamp are both provided with arc-shaped blocks. The arc-shaped blocks are uniformly provided with a plurality of strip-shaped openings in the radial direction. The telescopic elastic force adjusting mechanism is installed in each strip-shaped opening. The baffle is detachably installed on the arc-shaped block and is arranged on the front and back sides of the strip-shaped opening.

[0012] In the second usage state: the zinc block is installed in the strip-shaped opening, and one side of the zinc block abuts against the telescopic elastic force adjustment mechanism, and the other side abuts against the water supply pipe.

[0013] Furthermore, the telescopic elastic force adjustment mechanism includes a top plate, a spring, a telescopic plate and an adjusting bolt. The adjusting bolt is threadedly connected to the lower clamp and its end extends into the strip opening. One side of the telescopic plate is rotatably connected to the end of the adjusting bolt. A top plate is provided on the other side of the telescopic plate. A spring is provided between the top plate and the telescopic plate.

[0018] Furthermore, the rolling plate includes a plate and rollers, and a plurality of groups of rollers are evenly arranged on the top of the plate.

[0019] The present invention also provides a method for using a tunnel water supply pipe support device, comprising the following steps:

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0039] Referring to the drawings Figure 1 , a tunnel water supply pipeline support device includes a lower clamp 1, an upper clamp 2 and a base 3. The lower clamp 1 is fixed on the base 3, and the upper clamp 2 is detachably connected with the lower clamp 1 through bolts and nuts. By tightening, the water supply pipe 9 can be tightly fixed. The support device further includes an elastic extension adjusting mechanism 4, an arc block 5, a baffle 6, a zinc block 7 and a rolling plate 8. The inner walls of the lower clamp 1 and the upper clamp 2 are both provided with the arc block 5. The arc block 5 is uniformly provided with a plurality of strip-shaped openings in the radial direction. Each strip-shaped opening is provided with the elastic extension adjusting mechanism 4. The baffle 6 is detachably installed on the arc block 5 through bolts and is provided on both sides of the strip-shaped opening. The baffle 6 can prevent the zinc block 7 and the rolling plate 8 from falling out of the strip-shaped opening.

[0040] The tunnel water supply pipeline support device includes a first use state and a second use state.

[0041] Refer to the attached Figure 3 As shown, in the first use state: the rolling plate 8 is installed in the strip opening, and one side of the rolling plate 8 abuts against the telescopic elastic adjustment mechanism 4, and the other side abuts against the water supply pipe 9. The rolling plate 8 includes a plate 81 and rollers 82. A plurality of rollers 82 are evenly arranged on the top of the plate 81 (as shown in the attached figure). Figure 7 During use, the roller 82 on the rolling plate 8 is adjusted so that the protruding strip opening contacts the outer wall of the water supply pipe 9. When the water supply pipe 9 is pushed or pulled so that the two ends of the water supply pipe 9 are connected, the roller 82 on the rolling plate 8 rolls, thereby reducing the movement resistance of the water supply pipe 9, facilitating the pushing and pulling of the water supply pipe 9, and reducing the difficulty of installing the water supply pipe 9.

[0042] Refer to the attached Figure 2 and 4 As shown, in the second use state: the zinc block 7 is installed in the strip-shaped opening, and one side of the zinc block 7 abuts against the telescopic elastic adjustment mechanism 4, and the other side abuts against the water supply pipe 9; wherein, the side wall of the zinc block 7 abutting against the water supply pipe 9 is provided with an arc that matches the outer wall of the water supply pipe 9, so that the zinc block 7 and the steel water supply pipe can be tightly attached (as shown in the attached figure). Figure 6 When in use, the zinc block 7 is tightly attached to the steel water supply pipe 9 by the telescopic elastic adjustment mechanism 4. Since zinc is more active than iron, when oxidative corrosion occurs, the metallic zinc will be consumed first, thereby avoiding oxidation of the steel pipe.

[0043] When the zinc block 7 needs to be replenished and replaced due to oxidation loss, the baffles 6 on both sides are removed, and the telescopic elastic adjustment mechanism 4 is adjusted to remove the extrusion force, and then the zinc block 7 in the strip opening is pushed out, replaced and inserted with a new zinc block 7, and then the baffle 6 is reinstalled. This arrangement facilitates the replacement and replenishment of the zinc block 7 after oxidation loss.

[0044] Refer to the attached Figure 2 As shown, the telescopic elastic force adjustment mechanism 4 includes a top plate 41, a spring 42, a telescopic plate 43, and an adjusting bolt 44. The adjusting bolt 44 is threadedly connected to the lower clamp 1 and its end extends into the strip-shaped opening. One side of the telescopic plate 43 is rotatably connected to the end of the adjusting bolt 44. The other side of the telescopic plate 43 is provided with a top plate 41. A spring 42 is provided between the top plate 41 and the telescopic plate 43. The ends of the spring 42 are respectively fixedly connected to the top plate 41 and the telescopic plate 43. During use, the telescopic plate 43 is moved by turning the adjusting bolt 44, thereby adjusting the extrusion force of the spring 42.

[0045] In the first use state (such as Figure 3As shown), by tightening the adjusting bolt 44, the top plate 41 presses the roller plate 8. When pushing or pulling the water supply pipe 9 to move, if a foreign object or protrusion on the outer wall of the water supply pipe 9 passes through the roller 82, the spring 42 will be compressed to avoid it, thereby preventing the water supply pipe 9 from getting stuck and unable to be dragged.

[0046] In the second use state (such as Figure 2 As shown in the figure, by turning the adjusting bolt 44, the top plate 41 presses the zinc block 7. When the oxidation loss of the zinc block 7 decreases, the elastic force of the spring 42 is released, so that the zinc block 7 can always be closely attached to the steel water supply pipe 9. When the zinc block 7 needs to be replaced, the adjusting bolt 44 is rotated to retract the telescopic plate 43, completely releasing the squeezing force of the spring 42.

[0047] Refer to the attached Figure 5 As shown, a chute 51 is provided on both sides of each strip-shaped opening. A slider 11 is connected to both sides of the top plate 41 and the telescopic plate 43. The slider 11 slides in the chute 51, and a pressure sensor 10 is installed on the top of the chute. The pressure sensor 10 is electrically connected to an external control system. As the zinc blocks 7 are gradually consumed, the elastic force of the spring 42 is gradually released, pushing the sliders 11 on both sides of the top plate 41 upward. When the zinc blocks 7 are reduced to a certain level and need to be replaced, the sliders 11 contact the pressure sensor 10 and generate a pressure signal, which can be monitored by the staff through the external control system. This setting serves to remind the staff to replace the zinc blocks 7 in a timely manner, avoiding the inconvenience of manual inspection one by one.

[0048] Refer to the attached Figure 1 As shown, the base 3 includes a base 31, a threaded rod 32, and a fixing nut 33. The threaded rod 32 is fixed to both sides of the bottom of the lower clamp 1. The lower end of the threaded rod 32 passes through the top platform of the base 31. The threaded rod 32 is fixed to the base 31 via the fixing nut 33. The user can adjust the extension and contraction of the lower clamp 1 by turning the fixing nut 33, which facilitates the alignment of the ports during pipeline installation.

[0049] This embodiment also provides a method for using a tunnel water supply pipe support device, comprising the following steps:

[0050] 1) First, fix the base 3 to the installation location of the pipe, then place the water supply pipe 9 in the lower clamp 1, and install the upper clamp 2 on the lower clamp 1 with bolts and nuts. At this time, the bolts and nuts are not tightened, and the lower clamp 1 and the upper clamp 2 are in a loose state;

[0051] 2) Remove the baffle 6 on one side and place the roller plate 8 into each strip opening, with the roller 82 of the roller plate 8 facing the water supply pipe 9 during installation, and then install the baffle 6 back on the arc block 5; the installation of the baffle 6 can prevent the roller plate 8 from being pulled out during the pushing and pulling of the water supply pipe 9.

[0052] 3) Tighten the adjusting bolts 44 so that the rollers 82 on the rolling plate 8 protrude from the strip opening and abut against the water supply pipe 9. Then, adjust the fixing nuts 33 on the base 3 and push and pull the water supply pipe 9 to move the two ends of the water supply pipes 9 so that the ends of the two water supply pipes 9 are connected. Then, tighten the adjusting bolts 44 so that the rollers 82 on the rolling plate 8 are retracted into the strip opening and gradually tighten the bolts and nuts so that the arc block 5 is in contact with the water supply pipe 9. At the same time, fine-tune the fixing nuts 33 to align the ends of the two water supply pipes 9.

[0053] 4) Connect the two water supply pipes 9. After the two ports are connected, completely tighten the bolts and nuts to make the arc block 5 hold the water supply pipe 9 tightly;

[0054] 5) Remove the baffle 6 on one side and take out the roller plate 8 (the roller plate 8 can be reused), and insert the zinc block 7 into the strip-shaped opening. Then, install the baffle 6 back on the arc block 5, and tighten the adjusting bolt 44 to make the arc surface of the zinc block 7 fit tightly against the water supply pipe 9;

[0055] 6) When a new zinc block 7 needs to be replaced, loosen the adjusting bolt 44 to retract the telescopic plate 43 and completely release the elastic force of the spring 42. Then remove the baffles 6 on both sides, push out the zinc block 7 in the strip opening and insert a new zinc block 7. Then tighten the adjusting bolt 44 to make the arc surface of the zinc block 7 fit tightly against the water supply pipe 9.

[0056] As described above, after tightening the adjusting bolt 44 in steps 5) and 6), the spring 42 is in a compressed state.

[0057] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
