Description

Technical Field

[0001] This invention belongs to the field of pipeline construction technology, and specifically relates to a road pipeline construction device. Background Technology

[0002] In the construction and maintenance of municipal roads, pipeline laying is one of the core processes, and its construction quality directly affects the operational stability and service life of the road pipelines. Currently, the mainstream pipeline connection methods in road construction mainly include flange connections, welding connections, socket clamp connections, and flexible sleeve connections. However, these existing technologies still have many pain points that urgently need to be addressed in practical applications:

[0003] Firstly, pipe connection is inefficient and has a high operational threshold. Traditional flange connections require tightening multiple bolts one by one, necessitating specialized tools such as wrenches and torque meters, as well as multiple operators. A single connection typically takes over 30 minutes, especially in narrow road pits where tool maneuvering is limited, further reducing construction efficiency. Welding connections, on the other hand, require highly skilled operators and are greatly affected by on-site humidity and temperature, easily leading to quality issues such as incomplete welds and cracks. Post-weld anti-corrosion treatment is also required, making the process cumbersome. Even existing socket-type structures often lack effective guiding mechanisms, requiring repeated calibration of pipe coaxiality during connection. Even slight deviations can lead to connection failure, increasing the operational difficulty.

[0004] Secondly, the pipe diameter compatibility is poor, leading to high construction costs. Municipal road pipelines often involve various pipe diameters (such as DN100-DN500). Existing docking devices are mostly custom-designed for single pipe diameters, requiring construction units to stock a large number of connectors of different specifications for different pipe diameters. This not only occupies storage space but also significantly increases equipment procurement and management costs. While some adjustable docking structures can accommodate a small number of similar pipe diameters, the clamping gap is mostly adjusted manually with bolts. The adjustment process is time-consuming and prone to uneven clamping force, failing to meet the needs of rapid construction. Furthermore, the sealing performance decreases significantly after adjustment, easily leading to the risk of pipe leakage.

[0005] Third, the pipeline support positioning stability is insufficient, which easily leads to docking deviations. Road construction areas often have undulating or uneven surfaces. Existing pipeline supports mostly use temporary steel pipe supports or sandbag stacks. The height adjustment of the supports depends on adding or removing wooden blocks, which is cumbersome and cannot achieve fine-tuning. This causes the pipeline axis to easily shift, thus affecting the docking accuracy. Although some telescopic outrigger structures can adjust the height, they lack effective angle self-adaptation capabilities. On sloping roads, the support plate cannot fully fit the ground, which can easily lead to slippage or tipping. This not only affects construction safety but may also cause displacement of the docked pipeline, requiring disassembly and readjustment, further extending the construction period.

[0006] Fourth, sealing performance and durability are difficult to balance. Road pipelines are in a damp underground environment for a long time, and some pipelines need to transport pressurized fluids. The existing sealing structures mostly rely on a single rubber sealing ring. Affected by pipeline vibration or temperature changes, the sealing ring is prone to aging and deformation, leading to sealing failure. At the same time, the interlocking parts are mostly in direct metal-to-metal contact and lack effective anti-corrosion treatment. Long-term use can easily lead to rust and jamming, which not only affects later maintenance and disassembly, but may also cause the interlocking structure to fail, resulting in pipeline detachment accidents.

[0007] In summary, the current field of road pipeline construction urgently needs a construction device that combines efficient connection, compatibility with multiple pipe diameter specifications, stable support and positioning, and reliable sealing performance. This device would solve problems such as cumbersome operation, poor versatility, insufficient stability, and potential sealing hazards in existing technologies, thereby improving pipeline construction efficiency and project quality, and reducing construction costs and subsequent maintenance risks. Summary of the Invention

[0008] To address the aforementioned technical problems in existing road pipeline construction, this invention provides a road pipeline construction device.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0010] A road pipeline construction device includes an annular positioning seat, an annular engaging component, and elastic claws. The annular positioning seat is disposed at the end of a first pipeline, and the annular engaging component is disposed at the end of a second pipeline.

The first fixing block is provided with a first arc-shaped rubber pad, and the elastic claw is connected to the first fixing block.

[0012] The elastic claw includes a telescopic rod and an arc-shaped claw. One end of the telescopic rod is connected to the first fixed block, and the other end of the telescopic rod is connected to the arc-shaped claw. The arc-shaped clamping head is disposed on the arc-shaped claw, and the guide slope is disposed at the end of the arc-shaped claw. The arc-shaped claw is made of spring steel, and a deformation gap is provided between adjacent arc-shaped claws.

[0013] The inner wall of the annular locking component is provided with several second pipe diameter adjustment structures distributed circumferentially, and the positions of the second pipe diameter adjustment structures correspond one-to-one with those of the first pipe diameter adjustment structures.

[0014] The second pipe diameter adjustment structure includes a second adjustment groove, a second high-stiffness spring, a second fixing block, and a second arc-shaped rubber pad. The second adjustment groove is fixedly connected to the inner wall of the annular locking member. One end of the second high-stiffness spring is connected to the bottom of the second adjustment groove, and the other end of the second high-stiffness spring is connected to the second fixing block. The second fixing block is provided with a second arc-shaped rubber pad, and an annular platform is connected to the second fixing block. The annular locking groove is provided on the annular platform.

[0015] The front end of the annular platform is provided with a tapered guide with a gradually decreasing diameter. The tapered guide and the annular groove are connected by a circular arc surface. Both the annular groove and the arc-shaped head are coated with waterproof sealing material.

[0016] The annular positioning seat has telescopic legs symmetrically arranged on both sides. Each telescopic leg includes an outer tube, an inner rod, and an elastic locking pin. The annular positioning seat is fixedly connected to the outer tube. The outer tube is sleeved on the inner rod. The side wall of the outer tube has several positioning holes distributed along the axial direction. The upper part of the inner rod has a mounting groove adapted to the elastic locking pin. One end of the elastic locking pin passes through the positioning hole and extends out of the outer tube. The other end of the elastic locking pin is connected to the bottom of the mounting groove through a compression spring. The bottom of the inner rod has a support plate with anti-slip texture.

[0017] The extended end of the elastic locking pin is provided with a hemispherical pressing head, and the outer side of the hemispherical pressing head is covered with an anti-slip rubber sleeve.

[0018] The support plate has a ball head at the top, and the inner rod has a ball socket at the bottom that mates with the ball head. The edge of the ball socket has a limiting flange for limiting the rotation angle of the ball head.

[0019] The outer tube is provided with a folding operating lever in the middle. The folding operating lever is rotatably connected to the outer tube through a damping shaft. The side wall of the outer tube is provided with an arc-shaped groove for storing the folding operating lever. The end of the folding operating lever is provided with a detachable rubber grip. The surface of the grip is provided with axial anti-slip stripes.

[0020] Compared with the prior art, the beneficial effects of this invention are:

[0021] 1. This invention utilizes the combination design of the annular positioning seat and the annular locking component, along with the guide slope of the elastic claw and the arc-shaped locking head structure, to achieve rapid positioning and automatic locking of the pipeline. It eliminates the need for bolt tightening or welding operations, allowing a single person to complete the docking operation, significantly shortening construction time. The dual guiding effect of the guide slope and the conical guide reduces the calibration requirements for pipeline coaxiality and minimizes operational errors.

[0022] 2. The first and second pipe diameter adjustment structures of this invention can adapt to the outer wall size of pipes with different pipe diameters by means of the elastic expansion and contraction characteristics of high-stiffness springs, without the need to configure special connectors for each pipe diameter, thus reducing the amount of equipment required. The telescopic rod and deformation gap design of the elastic claw further expand the adaptation range, while ensuring uniform distribution of clamping force, avoiding the problem of reduced sealing performance of traditional adjustable structures.

[0023] 3. The precise fit between the arc-shaped clamp head and the annular groove of this invention, combined with the waterproof sealing material on both surfaces, forms a multi-layer sealing structure. Compared with the traditional single rubber sealing ring, it effectively improves the sealing effect and prevents pipeline leakage. The arc-shaped clamp claw made of spring steel has excellent elastic recovery ability, which can offset the slight displacement of the pipeline caused by temperature changes or vibration, ensuring the stability of the clamping structure during long-term use.

[0024] 4. The telescopic outriggers of this invention achieve rapid height adjustment through elastic locking pins. Combined with the adaptive angle structure of the ball head and ball socket, the support plate can maintain good contact on inclined roads, solving the problem of slippage or tipping of traditional supports. The support plate with anti-slip texture and the limiting flange design further enhance the overall stability and ensure that the axis does not deviate during pipeline docking.

[0025] 5. The folding operating lever of this invention can be flexibly adjusted in angle via a damping pivot, and fits snugly against the arc-shaped groove of the outer tube when stored, reducing space occupation; the anti-slip design of the rubber grip and the ergonomic structure of the hemispherical pressing head improve operating comfort and reduce construction fatigue; the quick locking function of the elastic locking pin avoids the cumbersome operation of traditional bolt adjustment, while preventing the outriggers from accidentally extending or retracting, thus improving construction safety.

[0026] 6. The adjustment structures of this invention are made of fatigue-resistant materials such as spring steel and high-stiffness springs, and are protected against corrosion by anti-slip rubber sleeves, which improves the durability of the device in underground humid environments; the detachable rubber grips and modular elastic claw design facilitate the replacement of local parts and reduce maintenance difficulty and cost.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. These descriptions are only for further illustrating the features and advantages of the present invention, and not for limiting the claims of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this embodiment, as Figure 1 As shown, during road pipeline connection construction, the annular positioning seat 1 is first installed and fixed at the end of the first pipeline, and the annular engaging component 2 is installed and fixed at the end of the second pipeline. When the two pipelines need to be connected, the two pipelines are pushed closer to each other, and the annular engaging component 2 moves inward to the annular positioning seat 1. At this time, the guide slope 302 at the end of the elastic claw 3, which is inclined outward, will contact the annular engaging component 2. The guide slope 302 plays a guiding role, allowing the annular engaging component 2 to smoothly enter the inner side of the annular positioning seat 1. As the two pipelines continue to approach, the arc-shaped clamping head 301 protruding in the middle of the elastic claw 3 will gradually align with the annular groove 201 on the annular engaging component 2. When the arc-shaped clamping head 301 is fully engaged in the annular groove 201, the initial positioning and connection of the first pipeline and the second pipeline are achieved, preventing the two pipelines from axially separating during subsequent construction or use.

[0045] Furthermore, such as Figure 2 As shown, the first pipe diameter adjustment structure 4 on the inner wall of the annular positioning seat 1 can adapt to different pipe diameters. When the first pipe passes through the inner side of the annular positioning seat 1, the outer wall of the first pipe will contact and compress the first arc-shaped rubber pad 404. The first arc-shaped rubber pad 404 drives the first fixing block 403 to move into the first adjustment groove 401, while compressing the first high-stiffness spring 402. The first high-stiffness spring 402 will generate a reverse elastic force, which tightly clamps the first pipe through the first fixing block 403 and the first arc-shaped rubber pad 404, thereby adapting to the fixing requirements of first pipes with different diameters. Since the elastic claw 3 is connected to the first fixing block 403, when the first fixing block 403 adjusts its position according to the pipe diameter, it will simultaneously drive the elastic claw 3 to adjust its position, ensuring that the elastic claw 3 can always accurately cooperate with the annular groove 201 on the annular locking member 2, without affecting the docking and positioning of the two pipes.

[0046] Furthermore, such as Figure 3 As shown, the telescopic rod 303 of the elastic jaw 3 can flexibly adjust its length according to the change in the diameter of the first pipe and the docking distance with the annular locking member 2, so that the arc-shaped jaw 304 can always be in a suitable docking position. The arc-shaped jaw 304 is made of spring steel and has good elastic deformation capability. When the annular locking member 2 approaches, the arc-shaped jaw 304 can adapt to the shape of the annular locking member 2, which facilitates the docking of the arc-shaped jaw head 301 with the annular jaw groove 201. The deformation gap between adjacent arc-shaped jaws 304 can provide space for the independent deformation of a single arc-shaped jaw 304, avoid mutual interference between adjacent arc-shaped jaws 304, and ensure that each arc-shaped jaw head 301 can be smoothly locked into the annular jaw groove 201, further improving the stability and reliability of the docking of the two pipes.

[0047] Furthermore, such as Figure 4As shown, when the second pipe is inserted into the inner side of the annular locking member 2, the outer wall of the second pipe presses against the second arc-shaped rubber pad 504. The second arc-shaped rubber pad 504 drives the second fixing block 503 to move into the second adjusting groove 501, compressing the second high-stiffness spring 502. The reverse elastic force of the second high-stiffness spring 502 firmly clamps the second pipe through the second fixing block 503 and the second arc-shaped rubber pad 504, thus fixing the second pipes of different diameters. Because the annular platform 202 is connected to the second fixing block 503, when the second fixing block 503 adjusts its position according to the pipe diameter, it will drive the annular platform 202 to move synchronously. The annular slot 201 is set on the annular platform 202, thereby ensuring that the annular slot 201 can always be precisely aligned with the elastic claw 3 on the annular positioning seat 1, ensuring the matching accuracy of the locking structure during the docking of the first and second pipes, and achieving stable docking.

[0048] Furthermore, such as Figure 5 As shown, during the docking process between the annular engaging component 2 and the annular positioning seat 1, the tapered guide portion 203 with a gradually decreasing diameter at the front end of the annular platform 202 first contacts the elastic claw 3. The tapered structure guides the elastic claw 3, causing it to gradually move towards the annular groove 201, reducing the difficulty of docking. When the arc-shaped head 301 of the elastic claw 3 approaches the annular groove 201, the arc surface 204 between the tapered guide portion 203 and the annular groove 201 transitions, reducing the frictional resistance between the arc-shaped head 301 and the annular platform 202, avoiding obstruction of engagement due to sharp corner contact, and allowing the arc-shaped head 301 to slide more smoothly into the annular groove 201. Simultaneously, the waterproof sealing material coated on the annular groove 201 and the arc-shaped head 301 fills the gap between them after the arc-shaped head 301 is engaged in the annular groove 201, forming an effective waterproof sealing structure, preventing leakage of the medium inside the pipeline, and improving the sealing performance of the device.

[0049] Furthermore, such as Figure 6 As shown, the telescopic outrigger 6 consists of an outer tube 601, an inner rod 602, and an elastic locking pin 603. The outer tube 601 is fixedly connected to the annular positioning seat 1, and the inner rod 602 is sleeved inside the outer tube 601. When the support height needs to be adjusted, the elastic locking pin 603 is pressed, causing the elastic locking pin 603 to retract into the compression inner rod 602, compressing the compression spring 6031 in the mounting groove 6021 on the upper part of the inner rod 602, and disengaging from the positioning hole 6011 on the side wall of the outer tube 601. At this time, the inner rod 602 can be pushed to move axially along the outer tube 601. After adjusting to the target height, the elastic locking pin 603 is released, and the compression spring 6031 returns to its original position, pushing the elastic locking pin 603 into the corresponding positioning hole 6011 to achieve height fixation. The support plate 7 at the bottom of the inner rod 602 increases the friction with the ground through anti-slip texture, providing stable support for the annular positioning seat 1.

[0050] Furthermore, such as Figure 7As shown, the positioning holes 6011 distributed axially along the side wall of the outer tube 601 provide multiple height adjustment options for the inner rod 602, which can adapt to different roadbed surface heights; the end of the elastic locking pin 603 extending out of the outer tube 601 is fitted with an anti-slip rubber sleeve 6032, which increases the friction of the operator's hand when pressing, preventing slippage, and also buffers the pressing force, improving operating comfort; when it is necessary to finely adjust the height of the inner rod 602, the operator can press the elastic locking pin 603 through the anti-slip rubber sleeve 6032 to release the fixation between the inner rod 602 and the outer tube 601. After the adjustment is completed, the elastic locking pin 603 automatically engages with the positioning hole 6011, without the need for additional locking steps, simplifying the operation process and ensuring that the telescopic outrigger 6 can quickly adapt to the construction ground height.

[0051] Furthermore, such as Figure 8 As shown, the elastic locking pin 603 is installed in the mounting groove 6021 on the upper part of the inner rod 602. One end of the pin is connected to the bottom of the mounting groove 6021 via a compression spring 6031, and the other end normally extends outward through the positioning hole 6011 of the outer tube 601, thus fixing the inner rod 602 to the outer tube 601. When the anti-slip rubber sleeve 6032 of the extended end of the elastic locking pin 603 is pressed, the compression spring 6031 is compressed and contracted, and the elastic locking pin 603 retracts into the mounting groove 6021, releasing the restriction on the inner rod 602 and allowing the inner rod 602 to slide along the outer tube 601. When the inner rod 602 moves to the target position and the mounting groove 6021 aligns with the positioning hole 6011 of the outer tube 601, the compression spring 6031 releases its elastic potential energy, pushing the elastic locking pin 603 to extend again and engage with the positioning hole 6011, completing the height locking and ensuring a tight fit between the locking pin and the positioning hole 6011 to prevent loosening.

[0052] Furthermore, such as Figure 9 As shown, the support plate 7 has a ball head 701 at the top and a ball socket 6022 at the bottom of the inner rod 602 that mates with the ball head 701. The ball head 701 can rotate flexibly within the ball socket 6022, allowing the support plate 7 to automatically adjust its tilt angle according to the ground slope, ensuring that the bottom of the support plate 7 is in full contact with the ground and preventing the support point from being suspended due to uneven ground. The limiting flange 6023 on the edge of the ball socket 6022 can limit the rotation angle of the ball head 701, preventing the support plate 7 from tilting excessively and causing the device to become unbalanced. The anti-slip texture on the bottom of the support plate 7 further enhances the friction with the ground. Combined with the angle adaptation function of the ball head 701, the telescopic outrigger 6 can still provide stable and horizontal support for the annular positioning seat 1 on uneven roadbeds, ensuring the accuracy of pipeline docking.

[0053] Furthermore, such as Figure 10As shown, the middle of the outer tube 601 is connected to the folding operating rod 8 via a damping shaft 801. The damping shaft 801 provides stable rotational resistance, allowing the folding operating rod 8 to be fixed at any angle. When the overall position of the device needs to be adjusted, the operator unfolds the folding operating rod 8, holds the rubber handle 802 at its end, and pushes or pulls the telescopic outrigger 6 to fine-tune the position of the annular positioning seat 1. This eliminates the need to bend over and reduce labor intensity. The axial anti-slip stripes on the surface of the rubber handle 802 increase hand friction and prevent slippage during operation. When the folding operating rod 8 is not needed, it can be rotated around the damping shaft 801 and stored in the arc-shaped groove 6012 on the side wall of the outer tube 601, reducing the space occupied by the device and facilitating transportation and operation in confined spaces. The detachable design of the rubber handle 802 also facilitates future maintenance and replacement.

[0054] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
