Description

Technical Field

[0001] This utility model relates to the field of municipal engineering construction technology, and in particular to a municipal pipeline docking and positioning device. Background Technology

[0002] With the rapid development of municipal and industrial pipeline engineering, the quality of pipeline connection has become the core control point of pipeline construction, and its construction accuracy directly determines the structural safety and operation and maintenance reliability of the pipeline system.

[0003] Traditional municipal pipeline connection methods often employ a manual alignment process of "single-end fixing and single-end hoisting." However, this method suffers from drawbacks such as complex procedures, high labor costs, inconsistent construction quality, and susceptibility to damage to the pipeline itself and its anti-corrosion coating. Furthermore, it is highly dependent on the skill level of the operators, easily leading to quality issues such as pipeline alignment deviations and excessive misalignment at interfaces. This can also cause a decline in the durability and corrosion resistance of the pipeline during long-term service, ultimately increasing the risk of leakage after water supply. Therefore, it is necessary to develop a pipeline connection and positioning device with convenient operation and efficient alignment capabilities, along with corresponding operational methods, to shorten the construction period, improve connection accuracy, and reduce labor intensity and the skill requirements for personnel. Utility Model Content

[0004] The purpose of this invention is to provide a municipal pipeline docking and positioning device that solves the above-mentioned technical problems.

[0005] Therefore, the technical solution of this utility model is as follows:

[0006] A municipal pipeline docking and positioning device includes two pipe-holding bodies, which are coaxially spaced and fixedly connected as one unit by multiple connecting beams evenly distributed along the circumference. Each pipe-holding body is a circular ring formed by two semi-annular bodies that can be detachably docked and fixed. Multiple radial threaded through holes are evenly distributed along the circumference of each body, and the multiple radial threaded through holes are evenly distributed on the two semi-annular bodies. A screw-in vertical rod is provided in each radial threaded through hole, which passes through and is threaded into the radial threaded through hole. A jacking plate is vertically fixed to the inner end of the screw-in vertical rod, and a screw-in horizontal rod is vertically fixed to its outer end.

[0007] Furthermore, in the main body of the tube, the top end joints of the two semi-annular bodies extend outward and form first connecting lugs, and the two first connecting lugs are detachably and fixedly connected by first fixing bolts passing through bolt holes; the bottom end joints of the two semi-annular bodies extend outward and form second connecting lugs, and the two second connecting lugs are detachably and fixedly connected by second fixing bolts passing through bolt holes.

[0008] Furthermore, the two main pipes are the same size, the distance between them is 300mm to 500mm, and their inner diameters are 1.1 times the maximum outer diameter of the municipal pipeline.

[0009] Furthermore, the inner and outer ends of the screw-in vertical rod are respectively fixed vertically and centrally on the jacking plate and the screw-in horizontal rod.

[0010] Furthermore, a rubber pad with a thickness of 3mm-5mm is covered on the side of the jacking plate that abuts against the outer wall of the municipal pipeline.

[0011] Furthermore, the main body of the tube is formed by bending high-strength hot-rolled steel bars with a thickness of ≥5mm and a width of ≥10mm.

[0012] Furthermore, the connecting beam is made of high-strength steel plate with a thickness of ≥10mm, and its length is adapted to the design spacing between the two main pipe clamps.

[0013] Furthermore, the screw-in vertical rod uses high-strength long bolts with a length of 80mm-100mm and a diameter of 10mm-15mm.

[0014] Furthermore, the jacking plate is made of high-strength steel plate with a thickness of ≥4mm, and its cross-section is circular or square.

[0015] Furthermore, the screw-in crossbar is made of round steel with a length of 100mm-120mm and a diameter of 10mm-15mm.

It boasts advantages such as simple structure, high practicality, and low skill requirements for operators. The device features two fixedly connected pipe-holding bodies that fit together and are fitted onto the outer sides of the docking ends of two municipal pipeline sections. Each pipe-holding body has a screw-in vertical rod that allows for simultaneous multi-directional fine-tuning and fixation of the two pipeline interfaces.

Furthermore, the device employs a lightweight design, with each unit weighing less than 30kg, aligning with portable construction principles. Components can be quickly disassembled and assembled without the need for cranes, significantly improving on-site operational convenience and effectively ensuring docking quality during pipeline construction.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention.

[0020] See Figure 1 and Figure 2 The municipal pipeline docking and positioning device includes two pipe-holding bodies 2, which are coaxially spaced apart and fixedly connected as one unit by four connecting beams 3 evenly distributed along the circumference.

[0021] In the structural design of the pipe-holding body 2, each pipe-holding body 2 includes two semi-annular bodies that can be joined together to form a circular ring. The top joint ends of the two semi-annular bodies extend outward to form first connecting lugs, and each first connecting lug is provided with bolt holes, so that the two first connecting lugs can be detachably and fixedly connected by first fixing bolts 1 passing through the bolt holes. The bottom joint ends of the two semi-annular bodies extend outward to form second connecting lugs, and each second connecting lug is provided with bolt holes, so that the two second connecting lugs can be detachably and fixedly connected by second fixing bolts 7 passing through the bolt holes.

[0022] In terms of size design, the two pipe-holding bodies 2 are the same size, and their inner diameters are larger than the outer diameter of the municipal pipeline connection end. Specifically, the inner diameter of the pipe-holding body 2 is preferably set to 1.1 times the maximum outer diameter of the municipal pipeline to be connected, which not only ensures sufficient space for the municipal pipeline, but also reserves a reasonable gap for subsequent precise alignment.

[0023] In this embodiment, since the main body 2 of the pipe clamp is the core load-bearing component, it is preferably made of two semi-circular bodies formed by bending 5mm thick hot-rolled steel bars of Q345 material grade; the connecting beam 3 is made of Q345 low alloy high strength steel plate with a thickness of 10mm, a length of 500mm and a width of 100mm, and is welded and fixed to the two main bodies 2 of the pipe clamp by arc welding to form a rigid whole, so as to ensure that the mechanical performance of the device meets the overall deformation resistance requirements of the device; the first fixing bolt 1 and the second fixing bolt 7 are both M6 bolts.

[0024] In order to enable the installation and positioning of the device with municipal pipelines, four radial threaded through holes are evenly distributed along the circumference on each pipe body 2. Each radial threaded through hole is machined with an M16 standard internal thread using a tapping process.

[0025] Each radial threaded through hole is equipped with a screw-in vertical rod 5, which passes through and is threaded into the radial threaded through hole. The length of its inner end extending into the pipe body 2 can be adjusted by rotating the screw-in vertical rod 5. The position of the municipal pipeline can be precisely adjusted by the axial displacement of the screw-in vertical rod 5. The inner end of the screw-in vertical rod 5 is vertically fixed to the jacking plate 4, so that the inner end of the screw-in vertical rod 5 abuts against the outer wall of the port side of the municipal pipeline through the jacking plate 4. A screw-in horizontal rod 6 is vertically fixed to the outer end of the screw-in vertical rod 5 to facilitate manual operation of the screw-in vertical rod 5.

[0026] In the above structural design, the jacking plate 4, the screw-in vertical rod 5, and the screw-in horizontal rod 6 constitute a dynamic adjustment and positioning mechanism. This allows each pipe-holding body 2 to achieve synchronous adjustment and fixation of the municipal pipeline interface end in multiple directions through multiple dynamic adjustment and positioning mechanisms set in the circumferential direction, and to accurately achieve the centering adjustment of the two sections of municipal pipeline. In addition, the threaded engagement structure between the screw-in vertical rod 5 and the pipe-holding body 2 can utilize the frictional resistance between the two to form a secondary pull-out defense line, strengthening the anchoring ability of the screw-in vertical rod 5 to the relative setting position of the municipal pipeline. Combined with the four connecting beams 3 arranged along the axis of the pipe-holding body 2 to bear the vertical gravity load of the pipelines on both sides, a multi-point collaborative force system is formed, which greatly improves the overall bending and torsional deformation resistance of the device.

[0027] As a preferred technical solution in this embodiment, a rubber pad is covered on the side of the jacking plate 4 that abuts against the municipal pipeline. In practical applications, the elastic deformation of the rubber pad can buffer the clamping force and effectively protect the outer anti-corrosion layer of the pipeline from compression and wear, ensuring that the corrosion protection performance of the pipeline is not affected.

[0028] In this embodiment, considering that the main body 2 of the pipe clamp is formed by the joining of two semi-annular bodies, each semi-annular body has two radial through holes, and the two radial through holes are evenly distributed on the semi-annular body to balance the overall structural strength of the semi-annular body; wherein, the radial threaded through hole is designed as an M16 standard internal thread hole, the screw-in vertical rod 5 is a high-strength long screw with a length of 80mm and a diameter of 13mm, and its external thread is matched with the internal thread of the radial threaded through hole; the jacking plate 4 is a steel plate with a length × width × thickness of 30mm × 30mm × 4mm, which is fixed to the inner end of the screw-in vertical rod 5 by spot welding; the rubber pad is glued to the surface of the jacking plate 4, and its thickness is 3mm; the screw-in horizontal rod 6 is a round steel with a length of 100mm and a diameter of 8mm, which is welded and fixed by the outer end of the screw-in vertical rod 5 abutting against the middle side wall of the screw-in horizontal rod 6.

[0029] The following describes the specific usage of the municipal pipeline docking and positioning device and its high-precision and high-efficiency docking connection principle, taking the construction of municipal pipelines in a sewage treatment plant as an example.

[0030] First, place the two sections of municipal pipeline in the designated design location, clear debris and obstacles from the pipeline docking area to ensure a safe operating space for the docking operation. Excavate an operating space 800mm long, wider than the diameter of the municipal pipeline, and 300mm deep at the designed docking location. Hoist and lower the municipal pipeline to the design location. Remove the fixing bolts on the upper and lower sides of the two pipe-holding bodies 2 in the municipal pipeline docking positioning device, so that they can be lowered separately and fitted onto the docking locations of the two sections of municipal pipeline. The two parts are respectively aligned with the outer sides of the ports of the two sections of municipal pipeline and connected and fixed with fixing bolts.

[0031] Then, after the two pipe-holding bodies 2 are connected, the connecting vertical rods 5 are rotated sequentially through each horizontal rod 6 to make the jacking plate 4 press tightly against the outer wall of the municipal pipeline through the rubber pad. Since there are a total of 8 jacking plates 4 on the two pipe-holding bodies 2, they can be used to synchronously adjust the docking ends of the two municipal pipelines in different directions until the two municipal pipelines are completely aligned and docked. This alignment mechanism can synchronously adjust the spatial position of the pipelines on both sides to ensure that the deviation of the pipeline docking axis is controlled within the allowable range and to ensure docking accuracy.

[0032] Next, the pipeline joint is initially welded and fixed using argon arc welding. During the fixing, spot welding is required in four directions at the pipeline joint. After the spot welding is completed, the exposed pipeline connection seam is welded.

[0033] Finally, the municipal pipeline docking positioning device was removed, and the pipeline connection seam at the location blocked by the device was welded. After welding, the docking ends of the two municipal pipelines were coated with anti-corrosion paint, and the excavated foundation was backfilled. The docking construction of the two municipal pipelines was completed.

[0034] Through actual project construction verification, this municipal pipeline docking and positioning device ensures that the deviation of the pipeline docking axis is controlled within the allowable range by precisely adjusting the spatial position of the pipelines on both sides. It can efficiently and accurately complete the pipeline docking operation, significantly improve the convenience and standardization of on-site operation, and greatly reduce labor input and construction time, thus achieving optimized control of construction costs.
