Description

Background Art

[0001] The pipeline system in the subway tunnel refers to the pipeline system used for transporting various fluid media (such as water, gas, oil) or power transmission inside the subway tunnel. These pipelines are crucial for the normal operation of the subway system. The pipelines are usually hoisted at the top of the tunnel to save space and keep the inside of the tunnel clean and tidy.

[0002] In the subway tunnel, the layout and protection of the pipelines are of great importance. Traditional pipeline suspension devices often have the following problems or deficiencies: The pipelines are usually simply tied or hung, lacking an effective separated wiring structure. When the vibration and sway during subway operation are transmitted to the pipelines, it is easy to cause the pipelines to be in an unstable state for a long time, and the pipelines collide with each other, resulting in pipeline wear and even damage, shortening the service life of the pipelines.

[0030] Next, in combination with the embodiments, the technical solutions of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0031] This embodiment provides a pipeline suspension protection device in a subway tunnel as shown in Figures 1-5 Figure, including: suspension assembly for subway tunnel pipelines 1, subway tunnel connection base assembly 2, suspension telescopic rod assembly 3, pipeline suspension wiring assembly 4;

[0032] The suspension assembly for subway tunnel pipelines 1 is installed in the subway tunnel for suspending the pipeline body 8;

[0033] The subway tunnel connection base assembly 2 is located above the suspension assembly for subway tunnel pipelines 1 and is used for directly connecting with the inner wall of the subway tunnel;

[0034] The suspension telescopic rod assembly 3 is located in the middle of the suspension assembly for subway tunnel pipelines 1 and is detachably installed at the bottom of the subway tunnel connection base assembly 2;

[0035] The pipeline suspension wiring assembly 4 is located below the suspension assembly for subway tunnel pipelines 1 and is installed at the bottom end of the suspension telescopic rod assembly 3 for suspending and wiring the pipeline body 8.

[0036] In this embodiment, the pipeline suspension wiring assembly 4 includes a suspension wiring frame box 7 directly fixed to the bottom of the suspension telescopic rod assembly 3, a square-rubber shock-absorbing pad frame 21 closely adhered to the inner wall of the suspension wiring frame box 7, a square mounting frame 22 closely adhered to the inner wall of the square-rubber shock-absorbing pad frame 21, and a corrugated wiring separation plastic buffer plate 12 installed in the inner cavity of the square mounting frame 22. The corrugated wiring separation plastic buffer plate 12 includes a plurality of pipeline wiring concave compartments 24 arranged at equal intervals for carrying the pipeline body 8 and an arched separation buffer part 28 between two adjacent pipeline wiring concave compartments 24. A plurality of compression springs 23 are symmetrically installed at the bottom of each arched separation buffer part 28. Through the design of the pipeline wiring concave compartments 24 and the arched separation buffer part 28, not only can the pipeline body 8 be separated and wired to prevent pipeline collisions or messy placement, ensuring the orderly arrangement of the pipelines, but also through the arched separation buffer part 28, the compression springs 23, and the corrugated wiring separation plastic buffer plate 12 which is made of thermoplastic elastomer (TPE): Thermoplastic elastomer (TPE) is a material that combines the characteristics of plastics and rubbers, has good elasticity and wear resistance, and also has good chemical resistance and temperature resistance. TPE also has good processing performance and is easy to mold, which can shock-absorb and buffer the pipeline body 8, thereby improving the stability of the pipeline body 8 wiring and the service life of the pipeline body 8. The square-rubber shock-absorbing pad frame 21 is closely adhered to the inner wall of the suspension wiring frame box 7 for further shock absorption and buffering. The square mounting frame 22 is closely adhered to the inner wall of the square-rubber shock-absorbing pad frame 21 and is used to install the corrugated wiring separation plastic buffer plate 12, providing stable installation support for the corrugated wiring separation plastic buffer plate 12.

[0037] In this embodiment, the subway tunnel connection base assembly 2 includes a base body 5 and a plurality of anchor rod members 10 symmetrically penetrating upward from the bottom surface of the base body 5. The anchor rod members 10 extend into the inner wall of the subway tunnel. A first rubber shock-absorbing pad 9 is adhered to the top surface of the base body 5. When the base body 5 is closely connected to the inner wall of the subway tunnel, the first rubber shock-absorbing pad 9 elastically abuts against the inner wall of the subway tunnel, playing a role in shock absorption and buffering, reducing the vibration transmitted to the device caused by subway operation, and improving the stability of the entire device. The base body 5, as the main component of the subway tunnel connection base assembly 2, is connected to the inner wall of the subway tunnel through a plurality of anchor rod members 10. The anchor rod members 10 penetrate upward from the bottom surface of the base body 5 and extend into the inner wall of the subway tunnel, playing a fixing role.

[0038] In this embodiment, the suspension telescopic rod assembly 3 includes a suspension hollow cylinder 6 welded to the top surface of the suspension wiring frame box 7 and a suspension extension rod 11 longitudinally penetrating through the inner cavity of the suspension hollow cylinder 6 and extending out from the upper part.

[0039] In this embodiment, a clamping convex plate 15 is welded on the top surface of the suspension extension rod 11, and a clamping groove 14 is provided inside the base body 5 for the clamping convex plate 15 to be detachably clamped. The outer walls on both sides of the base body 5 are threadedly connected with locking screws 17, which penetrate into the clamping groove 14 and abut against the outer wall of the clamping convex plate 15. In this way, the clamping convex plate 15 is fixed in the clamping groove 14. When the clamping convex plate 15 needs to be removed, the locking screws 17 are first removed, so that the two locking screws 17 lose the clamping force on the clamping convex plate 15, so that the clamping convex plate 15 is extracted from the clamping groove 14 to complete the removal.

[0040] In this embodiment, the outer walls on both sides of the suspension hollow cylinder 6 are symmetrically longitudinally provided with travel grooves 13, and the outer walls on both sides of one end of the suspension extension rod 11 located in the inner cavity of the suspension hollow cylinder 6 and aligned with the travel grooves 13 are connected to the travel slider 18 through fixing bolts 27.

[0041] In this embodiment, when the suspension extension rod 11 is raised or lowered in the inner cavity of the suspension hollow cylinder 6, the travel slider 18 slides longitudinally in the travel groove 13. The travel groove 13 and the travel slider 18 are designed to limit the lifting and lowering of the suspension extension rod 11 to prevent the suspension extension rod 11 from being pulled out and falling off the suspension hollow cylinder 6; and when the suspension extension rod 11 needs to be removed, only the two fixing bolts 27 need to be removed to disengage the travel slider 18 from the suspension extension rod 11 from the travel groove 13, and the suspension extension rod 11 without a limiting effect can be disengaged and removed from the suspension hollow cylinder 6.

[0042] In this embodiment, a plurality of threaded through holes 19 are longitudinally and equidistantly formed on the outer wall of the other side of the suspension hollow cylinder 6, and a locking bolt 20 is threadedly connected in one of the threaded through holes 19. When the lifting position of the suspension extension rod 11 is determined, the locking bolt 20 is tightened to fix the position of the suspension extension rod 11.

[0043] In this embodiment, a buffer air spring 26 is installed on the inner bottom wall of the suspension hollow cylinder 6, and the top of the buffer air spring 26 elastically abuts against the bottom end of the suspension extension rod 11. The buffer air spring 26 can dampen and buffer the lifting and lowering of the suspension extension rod 11, which can not only prevent the lifting and lowering of the suspension extension rod 11 from getting stuck, but also can dampen and buffer the external collision force on the suspension extension rod 11 or the vibration caused by the shaking of the buffer pipeline body 8.

[0044] In this embodiment, a second rubber shock pad 16 is bonded to the top surface of the clamping convex plate 15. When the clamping convex plate 15 is clamped into the clamping groove 14, the second rubber shock pad 16 elastically abuts against the inner top wall of the clamping groove 14. The design of the second rubber shock pad 16 not only increases the clamping friction between the clamping groove 14 and the clamping convex plate 15, improves the clamping stability, but also has the function of shock absorption and buffering, further improving the stability of the device. The wave wiring separation plastic buffer plate 12 also includes bent connection parts 25 at both ends, and the free end of each bent connection part 25 is fixed to the inner wall of the square frame mounting frame 22.

[0045] Working principle: For this pipeline suspension protection device in the subway tunnel, the pipeline body 8 is placed into the pipeline wiring concave part 24 of the wave wiring separation plastic buffer plate 12 to ensure that the pipeline bodies 8 are separated for wiring, avoiding mutual collision. Through the design of the pipeline wiring concave part 24 and the arched separation buffer part 28, not only can the pipeline bodies 8 be separated for wiring to prevent the pipelines from colliding or being placed in a mess, but also through the arched separation buffer part 28, the compression spring 23 and the wave wiring separation plastic buffer plate 12 being made of elastic plastic material, shock absorption and buffering can be carried out on the pipeline body 8.

[0046] When the pipeline body 8 vibrates or shakes due to external factors, the wave wiring separation plastic buffer plate 12, the compression spring 23 and the arched separation buffer part 28 act together to provide a shock absorption and buffering effect. The first rubber shock pad 9 and the second rubber shock pad 16 provide additional shock absorption and buffering between the base body 5 and the inner wall of the subway tunnel and between the clamping convex plate 15 and the clamping groove 14. The buffer air spring 26 provides additional shock absorption and buffering for the suspension system to ensure the stable suspension of the pipeline body 8.

[0047] When it is necessary to adjust the suspension height of the pipeline body 8, loosen the locking bolt 20, adjust the position of the suspension extension rod 11 in the suspension hollow cylinder 6, and then re-lock the locking bolt 20. The stroke slider 18 smoothly moves up and down in the stroke groove 13 to ensure the smooth lifting and lowering of the suspension extension rod 11.

[0048] Regularly check the wear condition of all components. If wear or damage is found, replace them in time. Check whether the fixing bolts 27, the locking bolts 20 and the locking screw rods 17 are tightened. If there is looseness, tighten them in time.

[0049] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should fall within the protection scope of the appended claims of the present invention.
