Description

Technical Field

[0001] The invention relates to the technical field of pipeline guide docking, and in particular to a pipeline guide docking device for water conservancy pipe network construction. Background Art

[0002] During the construction of urban and rural water supply pipelines, it is often found that the tails of small-diameter branches of water supply pipelines are prone to bursting. When designing the pipeline network, usually only a single pilot-operated adjustable pressure reducing valve is set at the branch diversion point. For some water supply points with high water pressure, the consideration is not comprehensive enough, and the design depth is insufficient, which easily leads to insufficient pressure regulating capacity at the place where the head difference exceeds the limit, and often causes the tail pipe to burst. When dealing with the tail pipe burst, if the downstream water inlet valve is closed, the whole maintenance process is prone to shut-off water hammer, and there is also the problem of secondary pipe burst. At the same time, it is also not conducive to the construction of adding pressure reducing valves in stages. If the upstream valve is closed, it is extremely difficult and dangerous to start filling again after the long-distance gravity flow water supply pipeline is completely emptied, and filling takes a long time. It is impossible to quickly meet the water needs of residents. During the water test run, for lines with long distances and high water level differences where a single adjustable pressure reducing valve cannot effectively reduce the water pressure, a step-by-step method of adding pressure reducing valves is adopted without closing the upstream water inlet gate of the pipeline. During the construction process, the "first diversion, then installation" method is mainly adopted. According to the water pressure demand of the tail pipe, the position of the graded pressure reducing valve should be set on the downstream side of the graded pipe section. After the original straight section is cut off at the position of the additional pressure reducing valve, the pre-adjusted adjustable pressure reducing valve diversion section is immediately installed, giving priority to restoring water supply to residents downstream of the pipeline, and then the valve section is constructed. After the construction and installation of the adjustable pressure reducing valve is completed, the problem of repeated bursts of the water supply tail pipe can be fundamentally solved after debugging and pressure reduction; When constructing a regulating pressure reducing valve, welding is usually used. During welding, due to the heavy pipe, it is difficult to guide and connect the main pipe and the diversion section of the regulating pressure reducing valve to be welded. The water supply network needs to reach each household and is divided into a main pipe and a branch pipe. Both the main pipe and the branch pipe need to be welded with a regulating pressure reducing valve. The existing guiding and docking equipment cannot guide and connect the two welding methods. Therefore, we proposed a pipeline guiding and docking equipment for water conservancy pipeline network construction. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a pipeline guide docking device for water conservancy pipe network construction, comprising: A fixing plate, wherein two groups of fixing plates are provided, each group of fixing plates is provided with two fixing plates, and the two fixing plates in the same group are slidably connected on the sides close to each other, and the two fixing plates in different groups are fixedly connected with nuts on the sides away from each other, and a total of four nuts are provided, and the four nuts are symmetrically arranged, and the internal threads of the nuts are connected with locking components; A guide mechanism, wherein the guide mechanism is symmetrically arranged at the interval between the two sets of fixed plates, and the two sides of the two guide mechanisms that are far away from each other are fixedly connected to the sides of the two fixed plates on different sides that are close to each other; Wherein, the guiding mechanism comprises: A fork plate having a semicircular structure and used for circumferential guidance when welding branch pipes; A rotating assembly having a limiting structure for docking branch pipes located at different positions of the main pipe, wherein the side of the rotating assembly away from the fork plate is fixedly connected to the side of the fixed plate close to the fork plate, and the side of the rotating assembly away from the fixed plate is fixedly connected to the side of the fork plate close to the fixed plate; An assembly component having a fixed structure for coaxial docking on the main pipe, wherein the assembly component is fixedly connected to one side of the fork plate close to the central axis of the rotating component, and the two sets of fixed plates are respectively inserted into the outside of the main pipe, and the fixed plates on the same side are locked by cooperating with the locking component and the nut to fix them to the main pipe. When it is necessary to install a branch pipe or other accessories that need to be welded on the surface of the main pipe, the branch pipe is docked with the fork plate, the branch pipe is inserted into the main pipe, and the welder is guided along the trajectory of the semicircular structure of the fork plate to weld the branch pipe. When it is necessary to weld accessories at the interval between the two main pipes, the outer side of the part is fixed by the assembly component, and the position of the fork plate is adjusted to make the main pipe and the accessories coaxially docked to complete the guiding and docking. By setting two detachable sets of fixed plates, the structures on the two sets of fixed plates can independently complete the guided docking of accessories welded on the end face of the main pipe, and can also cooperate with each other to complete the guided docking of accessories welded on the surface of the main pipe. At the same time, the two fixed plates in the same group can be disassembled to facilitate disassembly after welding.

[0004] Furthermore, the fixing plate is configured as a semicircular ring, and the two fixing plates together constitute a full ring. A slot is provided on the side of the fixing plate away from the nut, and a slot is also provided on the side of the fixing plate away from the nut and close to the nut. The two fixing plates on the same side are clamped to each other through four slots. The arrangement of the slots enables the fixing plates on the same side to directly only slide radially, and cannot move axially after the clamping is completed, so that offset between the two fixing plates before the main pipe is completely fixed can be avoided, thereby avoiding affecting the fixing effect of the main pipe.

[0005] Furthermore, the locking assembly includes a bolt, which is arranged on a side of the nut away from the fixing plate, and the bolt is threadedly connected to the nut, a groove is provided on the side of the fixing plate away from the nut, and the groove is provided at the bottom of the inner side surface of the groove, one end of the bolt close to the nut is fixedly connected with a boss, and the boss is slidably engaged with the inner side surface of the groove, and the bolt is inserted into the nut and tightened. The boss is continuously engaged with the groove of the other fixing plate to complete the locking of the two fixing plates, and the other end of the fixing plate on the same side is also locked. The fixing plate forms a full circular ring, which is convenient for coaxial guiding. The setting of the bolt, under the torsion of the threaded connection, the boss can obtain a larger pressure and can be smoothly engaged with the groove of the other fixing plate, so that the elasticity required for the engagement can be set smaller, and it is not easy to fall off after locking.

[0006] Furthermore, a spring plate is fixedly connected to one side of the fixing plate close to the center of the circle, the spring plate is made of elastic material in a V-shape, and a plurality of the spring plates are evenly distributed along the circumference of the fixing plate, a clamping plate is fixedly connected to one side of the fixing plate away from the fixing plate, and the clamping plate is arranged as a part of a ring, and the two fixing plates on the same side approach each other, driving the clamping plates fixed on the two fixing plates to approach each other, the clamping plates contact the main pipe, the spring plate is squeezed, the spring plate is deformed, and the main pipe is fixed, the spring plate is arranged in a V-shape, and the V-shaped structure can provide uniform deformation with the clamping connection between the two fixing plates, so that the elastic force always points to the center of the ring where the fixing plate is located, avoiding the elastic force from generating a component force, ensuring that the clamping plate will not tilt, and the obtained elastic force can act on the main pipe, thereby achieving a better fixing effect, and since the clamping plate is arranged as a part of the ring, the cylindrical main pipe can be better fixed.

[0007] Furthermore, two groups of fork plates are arranged at the interval between the two groups of fixed plates, and the sides of the two groups of fork plates that are away from each other are fixedly connected with rotating components, and each group of fork plates has several fork plates evenly distributed along the circumference of the rotating component, and each fork plate is fixedly connected with an assembly component on one side close to the center of the fixed plate. The assembly components in the same group are distributed in a circle and can cooperate with each other to fix the accessories welded to the end of the main pipe. The sides of the two fork plates in different groups that are close to each other are butt-jointed to form a full circle, which can guide the branch pipe fixed on the surface of the main pipe and connect it to the surface of the main pipe.

[0008] Furthermore, the rotating assembly includes a semi-annular rail, and the sides of the two fixed plates on the same side away from the nut are fixedly connected to the semi-annular rail, and the inner side surface of the semi-annular rail is limited and slidable with a driving seat, and the side of the driving seat away from the semi-annular rail is fixedly connected to a distance-adjusting telescopic rod, and the end of the distance-adjusting telescopic rod away from the semi-annular rail is fixedly connected to the side of the fork plate close to the fixed plate, and the driving seat is provided with a plurality of positions corresponding to the fork plate and distributed along the circumference of the semi-annular rail. The assembly assembly fixes the coaxially fixed accessory, starts the distance-adjusting telescopic rod, and the distance-adjusting telescopic rod is extended and retracted, driving the fork plate and the assembly assembly to move, and finally driving the coaxial guiding between the accessory and the main pipe, adjusting the distance-adjusting telescopic rod to an appropriate length, completing the guiding of the main pipe and the accessory, and after completing the docking, another assembly assembly fixes the accessory, and the previous assembly assembly is released, driving the distance-adjusting telescopic rod of the previous rotating assembly to extend and retract, repeating the above steps, the accessory is stationary, and the two distance-adjusting telescopic rods Corresponding elongation and shortening, the circular ring formed by the two fork plates is aligned with the connection position of the accessories and the main pipe, and the welder is inserted into the intervals formed by all the fork plates in turn for spot welding. The evenly distributed fork plates can obtain even welding spots, thereby avoiding uneven force on the accessories and causing them to fall off. The assembly component is driven to loosen the accessories, and the drive seat is started. The drive seat rotates inside the semi-annular track, driving the fork plates, assembly components, and adjustable telescopic rods to rotate, and finally driving the welder to rotate to complete the entire coaxial welding. When welding on the surface of the main pipe, the positions of the two fork plates are adjusted in the same way to correspond to the welding positions. The drive seat is stationary, and the welder rotates along the circle formed by the fork plates to complete the welding of the circumferentially distributed accessories. The setting of multiple sets of corresponding fork plates allows multiple welding stations to be provided during circumferential welding, so that the welding of multiple accessories can be completed at the same time, and multiple sets of corresponding fork plates can be adjusted independently to complete the welding of accessories located at different axial positions at the same time.

[0009] Furthermore, the assembly component includes a groove plate, which is fixedly connected to one side of the fork plate near the center of the fixed plate, and the inner side surface of the groove plate is slidably connected to a connecting plate, and the side of the connecting plate away from the groove plate is fixedly connected to a fixing block, and the fixing block is elastic, and the side of the fixing block away from the fork plate is fixedly connected to a circular rubber pad, and a circular rubber pad is provided.

The welder is guided along the trajectory of the semicircular structure of the fork plate 41 to weld the branch pipe. When it is necessary to weld accessories at the interval between the two main pipes, the outer side of the part is fixed by the assembly component 43, and the position of the fork plate 41 is adjusted to make the main pipe and the accessories coaxially docked to complete the guidance and docking. By setting two detachable groups of fixed plates 1, the structures on the two groups of fixed plates 1 can independently complete the guided docking of accessories welded on the end face of the main pipe, and can also cooperate with each other to complete the guided docking of accessories welded on the surface of the main pipe. At the same time, the two fixed plates 1 in the same group can be disassembled to facilitate disassembly after welding.
