Description

Technical Field

[0001] This utility model relates to the field of underground pipeline technology, and in particular to a reinforced underground pipeline component. Background Technology

[0002] Buried insulated pipes are insulated pipes buried underground, serving as anti-corrosion protection. They have good cold resistance, waterproofing, corrosion resistance, and aging resistance, and are an important component of the insulation system. Some existing insulated pipes are directly buried in the soil, and the connection of the insulated pipes is mainly connected by support frames, lacking a fixed structure. When subjected to the weight of the soil for a long time, the support frames may tilt, causing the joints of the insulated pipes on both sides to be unable to be parallel and thus separating, thereby affecting the connection effect.

[0003] For example, a reinforced buried thermal insulation pipe disclosed in Chinese patent literature (publication number: CN218348129U) uses a connecting component on the outside of the sealing cover and the mutual cooperation between the internal connecting structures to stably connect the two pipe joints together, preventing the pipes from separating when the support tilts, thus improving the connection strength between the two pipes.

[0004] However, since the first and second threaded rods are located outside the sealing cap, long-term corrosion by soil can severely hinder subsequent pipe disassembly and maintenance. Furthermore, when reinforcing the pipe connection, it is necessary to first rotate the connecting plate to align with the top of the second threaded rod on the other pipe, then rotate the first threaded rod clockwise, and use the first threaded rod to drive one end of the connecting plate to fit over the second threaded rod. Finally, the clamping ring on the second threaded rod is rotated to press and fix the connecting plate. This cumbersome operation severely reduces construction efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology. Currently, the pipe connection reinforcement joints are exposed to the outside, which are prone to rust and corrosion, causing obstacles to disassembly and maintenance in the later stage. In addition, the reinforcement operation is cumbersome and reduces construction efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reinforced underground pipeline assembly includes an outer pipe, an internal reinforcing support mechanism, and an arc-shaped support bar. The outer surfaces of multiple arc-shaped support bars are arranged in a ring array and fixedly connected to the inner wall of the outer pipe. An arc-shaped reinforcing block is arranged in a linear array between two adjacent arc-shaped support bars. An inner pipe is fixedly connected to the inner surface of each of the multiple arc-shaped support blocks.

[0008] One end of the outer tube is provided with a connecting and reinforcing mechanism, and the connecting and reinforcing mechanism includes a first annular sealing connecting block. One side of the first annular sealing connecting block is fixedly connected to one end of the inner tube and the outer tube respectively. The other side of the first annular sealing connecting block is provided with slots arranged in an annular array. The inner wall of the slot is provided with a first storage groove.

[0009] Preferably, the inner top wall of the slot is provided with a second storage groove, and the inner bottom wall of the first storage groove is fixedly connected with a support spring, and one end of the support spring is fixedly connected with a movable rod.

[0010] Preferably, the outer side of the movable rod is movably sleeved with the inner wall of the first storage slot, and the upper end of the movable rod extends into the interior of the slot and is fixedly connected with a locking block.

[0011] Preferably, the outer side of the locking block is movably inserted into the inner wall of the second storage groove, and the outer side of the first annular sealing connecting block is provided with a third storage groove arranged in an annular array, and the inner bottom wall of the third storage groove is provided with a threaded hole.

[0012] Preferably, the lower end of the threaded hole is connected to the inner top wall of the second receiving groove, and the inner wall of the threaded hole is threaded with a countersunk hexagonal head bolt.

[0013] Preferably, the lower end of the internal hexagon countersunk bolt contacts the upper end of the locking block, and the other ends of the outer tube and the inner tube are fixedly connected to a second annular sealing connecting block, and one side of the second annular sealing connecting block is fixedly connected to a plug distributed in an annular array.

[0014] Preferably, the upper end of the insert block is provided with a locking hole, and one end of the insert block is provided with a guide groove, one end of the guide groove communicating with the inner wall of the locking hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this utility model, by strengthening the support mechanism and the connection reinforcement mechanism, the inner pipe is supported and protected by the cooperation of the arc-shaped support bar and the arc-shaped reinforcement block, the deformation of the outer pipe under external pressure is reduced, and the connection strength between the pipes is improved by the insertion cooperation of the locking hole and the locking block. This not only makes the operation convenient, but also facilitates the disassembly and maintenance in the later stage, thus improving the construction efficiency. Attached Figure Description

[0028] Example

[0029] like Figure 1-6 As shown, this utility model provides a technical solution: a reinforced underground pipeline assembly, including an outer pipe 1. This structure is the outer protective layer of the entire assembly, playing a key role in resisting most of the external pressure and erosion. The outer pipe 1 is provided with a reinforcing support mechanism, which includes arc-shaped support bars 2. The outer surfaces of multiple arc-shaped support bars 2 are arranged in a ring array and fixedly connected to the inner wall of the outer pipe 1. Between two adjacent arc-shaped support bars 2, arc-shaped reinforcing blocks 21 are arranged in a linear array. The inner surfaces of multiple arc-shaped support blocks are fixedly connected to an inner pipe 22. The inner pipe 22, as the direct carrier of the transport medium, can safely and stably perform its function under the dual protection of the arc-shaped support bars 2 and the arc-shaped reinforcing blocks 21.

[0030] One end of the outer tube 1 is provided with a connecting and reinforcing mechanism, which includes a first annular sealing connecting block 3. One side of the first annular sealing connecting block 3 is fixedly connected to one end of the inner tube 22 and the outer tube 1 respectively. The connection is fixed by high-strength welding or special sealant to ensure the sealing and integrity of the connection.

[0031] On the other side of the first annular sealing connecting block 3, there are slots 31 arranged in a ring array. The inner wall of the slot 31 is provided with a first storage groove 32, which provides a place for the internal moving parts to hide, ensuring the compactness and orderliness of the connection structure.

[0032] The inner top wall of the slot 31 is provided with a second storage groove 33, which cooperates with the first storage groove 32 to provide flexible space for connecting the locking component.

[0033] The inner bottom wall of the first storage slot 32 is fixedly connected to a support spring 34. The support spring 34 is made of high-quality alloy material, which has good elastic recovery ability and corrosion resistance. One end of the spring is fixedly connected to a movable rod 35. The surface of the movable rod 35 is finely polished and lubricated to ensure smooth sliding in the slot.

[0034] The outer side of the movable rod 35 is precisely fitted into the inner wall of the first storage slot 32, and the gap between the two is controlled within a very small range, effectively preventing foreign objects from entering and affecting the operation of the components. The upper end of the movable rod 35 extends into the interior of the slot 31 and is fixedly connected to a locking block 36. The locking block 36 is forged from high-hardness alloy steel and its shape fits the locking requirements to ensure a stable connection.

[0035] The outer side of the locking block 36 is movably inserted into the inner wall of the second storage groove 33. The fit between the two is tight and seamless, ensuring the precise execution of locking and unlocking actions. The outer side of the first annular sealing connecting block 3 is provided with a third storage groove 37 arranged in a ring array. The third storage groove 37 is used to store the head of the internal hexagon countersunk bolt 39 to prevent it from being exposed and damaged. The inner bottom wall of the third storage groove 37 is provided with a threaded hole 38. The inner wall of the threaded hole 38 is finely tapped to ensure that the internal hexagon countersunk bolt 39 is screwed in smoothly.

[0036] The lower end of the threaded hole 38 is connected to the inner top wall of the second receiving groove 33. This connection design allows the operation of the internal hexagon countersunk bolt 39 to directly act on the locking block 36. The internal hexagon countersunk bolt 39 is threadedly connected to the inner wall of the threaded hole 38. The specifications of the internal hexagon countersunk bolt 39 are strictly matched to the threaded hole 38 to ensure the reliability of the connection.

[0037] The lower end of the internal hexagon countersunk bolt 39 is in close contact with the upper end of the locking block 36. When the bolt is tightened, pressure can be accurately transmitted. The other ends of the outer tube 1 and the inner tube 22 are fixedly connected to the second annular sealing block 310. The material of the second annular sealing block 310 is the same as that of the first annular sealing block 3, ensuring the consistency of the connection at both ends.

[0038] The second annular sealing connecting block 310 has a fixed connection on one side with a ring array of insert blocks 311. The size of the insert blocks 311 perfectly matches the slot 31, ensuring a seamless connection.

[0039] The upper end of the insert 311 is provided with a locking hole 312. The depth and diameter of the locking hole 312 are precisely calculated to fit the insertion of the locking block 36. One end of the insert 311 is provided with a guide groove 313. One end of the guide groove 313 is connected to the inner wall of the locking hole 312. The width of the guide groove 313 is sufficient to allow the movable rod 35 to pass through smoothly, providing convenient guidance for the insertion of the insert 311.

[0040] The working process of this utility model:

[0041] Step 1: During connection, insert the plug 311 into the slot 31 on the other pipe. The guide groove 313 avoids the movable rod 35. When fully inserted, the locking hole 312 is located below the locking block 36. Tighten the hexagon countersunk bolt 39 so that its head moves into the third receiving groove 37. The sealing ring in the third receiving groove 37 prevents corrosion of the threads of the hexagon countersunk bolt 39. The lower end of the hexagon countersunk bolt 39 is pressed against the locking block 36 by the threaded hole 38. This causes the movable rod 35 to drive the support spring 34 to retract until the locking block 36 is fully inserted into the locking hole 312, thereby improving the connection strength between the two pipes.

[0042] Step 2, during maintenance and disassembly, rotate the internal hexagon countersunk bolt 39 in the reverse direction to screw its head back into the threaded hole 38. At this time, the elastic force of the support spring 34 drives the locking block 36 to rise and move through the movable rod 35, so that the locking block 36 rises and moves into the second storage slot 33, thereby releasing the restriction on the insertion block 311. Then, move the insertion block 311 to disengage it from the slot 31 to complete the disassembly.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
