Abstract

This invention discloses an auxiliary device and method for connecting branch pipes to ultra-large diameter pipes, relating to the field of pipelines. It includes a first pipe, a second pipe, and pipe foundation piles. The first and second pipes are interlocked, and the pipe foundation piles are installed on the ground, with two pipe supports mounted on them. It should be noted that, in this embodiment, during the installation of the first and second pipes, the two arc-shaped guide plates are pressed together to position both sides of the second pipe. Simultaneously, a pushing plate moves the clamp, causing the clamp to automatically insert the second pipe into the first pipe.

This makes pipe installation more convenient and accurate.

Description

Technical Field

[0001] This invention relates to the field of pipeline technology, and in particular to an auxiliary device and method for connecting branch pipes to ultra-large diameter pipelines. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] In the industrial sector, extra-large diameter pipes are often used to meet production demands. During installation, connecting two extra-large diameter pipes requires hoisting. It's important to note that hoisting necessitates specialized personnel to direct the operation and requires careful crane operator intervention to ensure proper alignment. This process is time-consuming, and errors can easily lead to pipe misalignment or even damage due to mutual compression between the pipes. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device and method for connecting branch pipes to ultra-large diameter pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0012] Furthermore, in a preferred embodiment of the present invention, a buffer groove is provided on the docking pull rod, and a buffer slide rod is slidably installed in the buffer groove;

[0013] The buffer slide is mounted on the docking push plate, and a buffer spring is installed on one side of the buffer slide. The buffer spring is installed on the inner wall of the buffer groove.

[0014] Furthermore, in a preferred embodiment of the present invention, the downward linkage auxiliary mechanism further includes a transfer drive plate, which is mounted on the bottom side of the docking pull-back rod;

[0015] The adapter drive plate has a drive sliding hole, and an adapter slide shaft is movably installed in the drive sliding hole. The adapter slide shaft is installed on the support lower pressure frame.

[0016] Furthermore, in a preferred embodiment of the present invention, a main support plate and an auxiliary support plate are respectively installed on the two supporting pressure frames, and the main support plate and the auxiliary support plate are interlocked with each other;

[0017] Both the main support plate and the auxiliary support plate are equipped with support springs, which are mounted on the support bracket.

[0018] Furthermore, in a preferred embodiment of the present invention, a synchronization plate is installed on one of the supporting pressure frames, and a synchronization slot is provided on the other supporting pressure frame, wherein the synchronization plate is inserted into the synchronization slot.

[0019] Furthermore, in a preferred embodiment of the present invention, the rotating downward positioning mechanism further includes a drive shaft, and the connecting bracket is provided with a drive groove, the drive shaft being rotatably installed in the drive groove;

[0020] A reset torsion spring is installed on the inner wall of the drive slot, and the reset torsion spring is mounted on the drive shaft.

[0021] Furthermore, in a preferred embodiment of the present invention, a rotating pull rod is installed at one end of the drive shaft, and a pull-down connecting rod is movably installed on one side of the rotating pull rod;

[0022] A linkage pull-down bracket is installed on one side of the adapter slide shaft. A pull-down extension groove is provided on the pull-down connecting rod. A pull-down extension rod is movably installed in the pull-down extension groove. The pull-down extension rod is installed on the linkage pull-down bracket. A pull-down extension spring is installed on the pull-down extension rod. The pull-down extension spring is installed on the inner wall of the pull-down extension groove.

[0023] A linkage slide shaft is rotatably mounted on the pull-down linkage rod, and a linkage slide hole is opened on one side of the rotating pull rod, and the linkage slide shaft is movably installed in the linkage slide hole.

[0024] Furthermore, in a preferred embodiment of the present invention, one of the rotating lower pressure plates is provided with a plurality of merging slots, and another rotating lower pressure plate is provided with a plurality of merging blocks, the plurality of merging blocks being inserted into the plurality of merging slots respectively.

[0025] An auxiliary method for connecting a branch pipe to an ultra-large diameter pipe, based on the aforementioned auxiliary device for connecting a branch pipe to an ultra-large diameter pipe, includes the following steps:

[0026] S1. Hoist the first pipe onto the pipe support, install the two merging supports onto the two pipe supports with bolts, then install the two push clamps onto the second pipe with bolts, so that the synchronous plug plate is inserted into the synchronous slot, and insert multiple merging blocks into multiple merging slots, and then hoist the second pipe and connect it to the first pipe.

[0027] S2. The second pipe is lowered and comes into contact with the two arc-shaped guide plates. The second pipe presses against the two arc-shaped guide plates, and the arc-shaped guide plates move horizontally in the return groove through the telescopic pull rod, which causes the return spring to be stressed. Under the return force of the return spring, the telescopic pull rod pulls the arc-shaped guide plates to reset, positioning the two sides of the second pipe and aligning them with the first pipe.

[0028] S3. The second pipe continues to descend, causing it to press against the main support plate and the auxiliary support plate, which in turn press against the two support lower pressure frames, which in turn move the two support lower pressure frames. The movement of the two support lower pressure frames drives the two transition sliding shafts to move. The transition sliding shafts move within the drive sliding holes, which in turn drive the transition drive plate to move. The movement of the transition drive plate drives the docking pull rod to move. The movement of the docking pull rod pushes the push clamp through the docking push plate, causing the push clamp to drive the second pipe to insert into the first pipe.

[0029] S4. The transition slide shaft moves down, causing the linkage pull-down bracket to move. The linkage pull-down bracket moves the pull-down connecting rod through the pull-down extension rod. The pull-down connecting rod drives the rotating pull rod to rotate through the linkage slide shaft. The linkage slide shaft moves in the linkage slide hole. The rotation of the rotating pull rod drives the rotating pressure plate to rotate through the drive shaft. The rotating pressure plate squeezes the top side of the second pipe and aligns it with the first pipe.

[0030] The beneficial effects of the auxiliary device and method for connecting branch pipes of ultra-large diameter pipes proposed in this invention are:

[0031] In this invention, by setting up a positioning and connecting mechanism on both sides, when installing the first pipe and the second pipe, the two arc-shaped guide plates are pressed to position the two sides of the second pipe, aligning the two pipes with the two sides of the first pipe, which facilitates the docking of the second pipe with the first pipe.

[0032] Furthermore, in this invention, by setting up a downward linkage auxiliary mechanism, when the two sides of the second pipe are aligned and continuously lowered, the second pipe causes the main support plate and auxiliary support plate to move, thereby causing the docking pull rod to push the clamp to move through the docking push plate, thereby causing the clamp to drive the second pipe to insert into the first pipe, thus realizing the function of automatic docking.

[0033] Furthermore, in this invention, by setting up a rotating downward positioning mechanism, when the second pipe is inserted into the first pipe, the rotating downward pressure plate squeezes the top side of the second pipe and aligns it with the first pipe, so that the second pipe and the first pipe are fully aligned, thereby ensuring that the second pipe and the first pipe can be fully and accurately connected when inserted.

[0053] Please refer to the attached instruction manual. Figures 1-12 The present invention provides an auxiliary device for connecting a branch pipe to an ultra-large diameter pipe, which includes a first pipe 1, a second pipe 2 and a pipe foundation pile 3. The first pipe 1 and the second pipe 2 are connected to each other. The pipe foundation pile 3 is installed on the ground. Two pipe supports 4 are installed on the pipe foundation pile 3. The first pipe 1 and the second pipe 2 are respectively placed on the two pipe supports 4.

[0054] Furthermore, this embodiment of the invention provides an auxiliary device for connecting branch pipes to ultra-large diameter pipes. Two merging supports 5 are movably installed on the pipe foundation pile 3. The two merging supports 5 are connected by bolts. Each of the two merging supports 5 is equipped with a two-sided positioning connection mechanism 6, which is used to position the two sides of the first pipe 1 and the second pipe 2. Specifically, the two-sided positioning connection mechanism 6 includes an arc-shaped guide plate 601. The two arc-shaped guide plates 601 are movably installed on one side of the two merging supports 5. A docking push plate 607 is movably installed on one side of each of the two merging supports 5. Two pushing clamps 608 are installed on the second pipe 2. The two pushing clamps 608 are connected by bolts. The movement of the docking push plate 607 pushes the pushing clamps 608 to move. A docking pull rod 606 is slidably installed on one side of the merging support 5, and the docking push plate 607 is installed on the docking pull rod 606.

[0055] It should be noted that, in this embodiment of the invention, when installing the first pipe 1 and the second pipe 2, the first pipe 1 is first hoisted onto the pipe support 4, and then the second pipe 2 is hoisted and connected to the first pipe 1. At this time, two merging supports 5 are installed on the two pipe supports 4 with bolts, and then two push clamps 608 are installed on the second pipe 2 with bolts. Then the second pipe 2 is hoisted and connected. When the second pipe 2 is lowered, the second pipe 2 contacts the two arc-shaped guide plates 601. If the position of the second pipe 2 is not correct, it will squeeze the two arc-shaped guide plates 601, causing the arc-shaped guide plates 601 to move horizontally in the pull-back groove 605 through the telescopic pull rod 603, and causing the pull-back spring 604 to be stressed. Therefore, under the pull-back force of the pull-back spring 604, the telescopic pull rod 603 pulls the arc-shaped guide plates 601 to reset, and then the two arc-shaped guide plates 601 position the two sides of the second pipe 2 to ensure that the second pipe 2 is aligned with the first pipe 1.

[0056] More specifically, in this embodiment of the invention, two downward linkage auxiliary mechanisms 7 are also included. These two mechanisms are respectively mounted on two merging supports 5 and are respectively connected to two side positioning connection mechanisms 6. Each downward linkage auxiliary mechanism 7 includes a support bracket 701, which is mounted on the merging supports 5. A downward support frame 702 is movably mounted on the support bracket 701 and is connected to the docking push plate 607. It should be noted that in this embodiment of the invention, when the two sides of the second pipe 2 are aligned and continuously lowered, the second pipe 2 presses the main support plate 704 and the auxiliary support plate 705 to move, causing the main support plate 704 and the auxiliary support plate 705 to press the two downward support frames 702 to move. This, in turn, causes the docking pull rod 606 to move and pushes the push clamp 608 through the docking push plate 607, thereby causing the push clamp 608 to drive the second pipe 2 into the first pipe 1, achieving the function of automatic docking.

[0057] More specifically, in this embodiment of the invention, two rotating downward positioning mechanisms 8 are further included. These two mechanisms are respectively mounted on two merging brackets 5. Each rotating downward positioning mechanism 8 includes a connecting bracket 801, which is mounted on the merging bracket 5. A rotating downward pressure plate 802 for pressing down on the first pipe 1 and the second pipe 2 is rotatably mounted on the connecting bracket 801. It should be noted that in this embodiment of the invention, when the second pipe 2 is continuously lowered, the rotating downward pressure plate 802 rotates, pressing the top side of the second pipe 2 and aligning it with the first pipe 1, thus ensuring full alignment between the second pipe 2 and the first pipe 1, thereby facilitating full docking between the second pipe 2 and the first pipe 1.

[0058] Please refer to the instruction manual attached. Figures 4-7 Furthermore, the auxiliary device for connecting branch pipes of ultra-large diameter pipes provided in this embodiment of the invention includes a side connecting seat 602 on one side of the merging bracket 5. In addition, a pull-back groove 605 is provided on one side of the side connecting seat 602, and a telescopic pull rod 603 is slidably installed in the pull-back groove 605. The telescopic pull rod 603 is installed on one side of the arc-shaped guide plate 601, and a pull-back spring 604 is installed on one side of the telescopic pull rod 603. The pull-back spring 604 is installed on the inner wall of the pull-back groove 605. It should be noted that in this embodiment of the invention, when the second pipe 2 is lowered, the second pipe 2 contacts the two arc-shaped guide plates 601. If the position of the second pipe 2 is not correct, it will squeeze the two arc-shaped guide plates 601, causing the arc-shaped guide plates 601 to move horizontally in the pull-back groove 605 through the telescopic pull rod 603, and causing the pull-back spring 604 to be stressed. Therefore, under the pull-back force of the pull-back spring 604, the telescopic pull rod 603 pulls the arc-shaped guide plates 601 to reset, thereby achieving the purpose of positioning both sides of the second pipe 2 through the two arc-shaped guide plates 601.

[0059] More specifically, in this embodiment of the invention, a buffer groove 609 is provided on the docking pull-back rod 606, and a buffer slide rod 610 is slidably installed in the buffer groove 609; the buffer slide rod 610 is installed on the docking push plate 607, and a buffer spring 611 is installed on one side of the buffer slide rod 610, and the buffer spring 611 is installed on the inner wall of the buffer groove 609. It should be noted that, in this embodiment of the invention, after the second pipe 2 and the first pipe 1 are docked, if the docking pull-back rod 606 is still moving, causing the docking push plate 607 to be pulled, and then the buffer slide rod 610 moves in the buffer groove 609, causing the buffer spring 611 to be stressed, providing a buffer distance for the docking push plate 607.

[0060] Please refer to the instruction manual attached. Figures 4-5 and Figure 8Furthermore, the auxiliary device for connecting a branch pipe to an ultra-large diameter pipe provided in this embodiment of the invention includes a downward linkage auxiliary mechanism 7 that further includes a transfer drive plate 706, which is installed on the bottom side of the docking pull-back rod 606.

[0061] Furthermore, the adapter drive plate 706 has a drive sliding hole 707, and an adapter sliding shaft 708 is movably installed in the drive sliding hole 707. The adapter sliding shaft 708 is mounted on the supporting lower pressure frame 702. It should be noted that, in this embodiment of the invention, the movement of the two supporting lower pressure frames 702 drives the movement of the two adapter sliding shafts 708. The adapter sliding shafts 708 move within the drive sliding hole 707, which in turn drives the adapter drive plate 706 to move. The movement of the adapter drive plate 706 drives the docking pull-back rod 606 to move, causing the docking pull-back rod 606 to slide within the merging bracket 5. The movement of the docking pull-back rod 606 pushes the pushing clamp 608 to move through the docking push plate 607, thereby causing the pushing clamp 608 to drive the second pipe 2 to insert into the first pipe 1, realizing the function of automatic docking.

[0062] More specifically, in this embodiment of the invention, a main support plate 704 and an auxiliary support plate 705 are respectively installed on the two supporting pressure frames 702, and the main support plate 704 and the auxiliary support plate 705 are interlocked with each other; in addition, a support spring 703 is installed on both the main support plate 704 and the auxiliary support plate 705, and the support spring 703 is installed on the support bracket 701. It should be noted that, in this embodiment of the invention, when the second pipe 2 is lowered, the main support plate 704 is squeezed downward, which in turn squeezes the auxiliary support plate 705 downward simultaneously, thereby realizing the synchronous downward movement of the two supporting pressure frames 702 and causing the two support springs 703 to be stressed.

[0063] More specifically, in this embodiment of the invention, a synchronization plate 709 is installed on one supporting lower pressure frame 702, and a synchronization slot 710 is provided on the other supporting lower pressure frame 702, with the synchronization plate 709 inserted into the synchronization slot 710. It should be noted that, in this embodiment of the invention, when one supporting lower pressure frame 702 is raised or lowered, the synchronization plate 709 drives the other supporting lower pressure frame 702 to rise or fall, thereby achieving synchronous movement of the two supporting lower pressure frames 702.

[0064] Please refer to the instruction manual attached. Figure 4 and Figures 9-12Furthermore, in this embodiment of the invention, the rotating downward positioning mechanism 8 further includes a drive shaft 811, and a drive groove 812 is provided on the connecting bracket 801. The drive shaft 811 is rotatably mounted in the drive groove 812. A reset torsion spring 813 is installed on the inner wall of the drive groove 812, and the reset torsion spring 813 is mounted on the drive shaft 811. It should be noted that in this embodiment of the invention, the rotation of the drive shaft 811 causes it to rotate within the drive groove 812, which in turn causes the reset torsion spring 813 to be subjected to force. Therefore, under the rebound force of the reset torsion spring 813, the drive shaft 811 can be helped to reset.

[0065] More specifically, in this embodiment of the invention, a rotating pull rod 803 is installed at one end of the drive shaft 811, and a pull-down connecting rod 805 is movably installed on one side of the rotating pull rod 803; a linkage pull-down bracket 804 is installed on one side of the adapter slide shaft 708, a pull-down extension groove 806 is provided on the pull-down connecting rod 805, a pull-down extension rod 807 is movably installed in the pull-down extension groove 806, the pull-down extension rod 807 is installed on the linkage pull-down bracket 804, a pull-down extension spring 808 is installed on the pull-down extension rod 807, and the pull-down extension spring 808 is installed on the inner wall of the pull-down extension groove 806;

[0066] In addition, a linkage slide shaft 810 is rotatably mounted on the pull-down linkage 805, and a linkage slide hole 809 is opened on one side of the rotating pull rod 803, with the linkage slide shaft 810 movably installed in the linkage slide hole 809. It should be noted that, in this embodiment of the invention, when the adapter slide shaft 708 moves downward, it drives the linkage pull-down bracket 804 to move, so that the linkage pull-down bracket 804 drives the pull-down connecting rod 805 to move through the pull-down extension rod 807. The pull-down connecting rod 805 drives the rotating pull rod 803 to rotate through the linkage slide shaft 810. At the same time, the linkage slide shaft 810 moves in the linkage slide hole 809. The rotation of the rotating pull rod 803 drives the rotating pressure plate 802 to rotate through the drive shaft 811, so that the rotating pressure plate 802 presses the top side of the second pipe 2 and aligns with the first pipe 1. In addition, after the rotating pull rod 803 rotates, if the linkage pull-down bracket 804 continues to move, it moves in the pull-down extension groove 806 through the pull-down extension rod 807, and the pull-down extension spring 808 is stretched by force, providing a buffer space for the linkage pull-down bracket 804.

[0067] Please continue to refer to the instruction manual appendix. Figure 4 and Figures 9-12More specifically, in this embodiment of the invention, one rotating lower pressure plate 802 has multiple merging slots 815, and the other rotating lower pressure plate 802 is equipped with multiple merging blocks 814, which are respectively inserted into the multiple merging slots 815. It should be noted that, in this embodiment of the invention, when the two rotating lower pressure plates 802 are merged, the multiple merging blocks 814 inserted into the multiple merging slots 815 ensure that the two rotating lower pressure plates 802 remain aligned, thereby guaranteeing that the second pipe 2 and the first pipe 1 are neatly stacked.

[0068] In summary, the working principle of the auxiliary device for connecting a branch pipe to an ultra-large diameter pipe provided in this embodiment of the invention, that is, the method corresponding to the auxiliary device for connecting a branch pipe to an ultra-large diameter pipe in this embodiment of the invention, is as follows:

[0069] When installing the first pipe 1 and the second pipe 2, the first pipe 1 is first hoisted onto the pipe support 4, and then the second pipe 2 is hoisted and connected to the first pipe 1. At this time, two merging brackets 5 are installed on the two pipe supports 4 with bolts, and then two push clamps 608 are installed on the second pipe 2 with bolts. Then the second pipe 2 is hoisted and connected. It should be noted that when the second pipe 2 is lowered, the second pipe 2 contacts the two arc-shaped guide plates 601. If the position of the second pipe 2 is not correct, it will squeeze the two arc-shaped guide plates 601, causing the arc-shaped guide plates 601 to move horizontally in the pull-back groove 605 through the telescopic pull rod 603, and causing the pull-back spring 604 to be stressed. Therefore, under the pull-back force of the pull-back spring 604, the telescopic pull rod 603 pulls the arc-shaped guide plates 601 to reset, and then the two arc-shaped guide plates 601 position the two sides of the second pipe 2 to ensure that the second pipe 2 is aligned with the first pipe 1.

[0070] Furthermore, as the second pipe 2 aligns with both sides and continues to descend, it causes the second pipe 2 to press against the main support plate 704 and the auxiliary support plate 705, which in turn press against the two supporting lower pressure brackets 702, causing the two support springs 703 to be stressed. The movement of the two supporting lower pressure brackets 702 drives the two transition sliding shafts 708 to move. The transition sliding shafts 708 move within the drive sliding holes 707, which in turn drives the transition drive plate 706 to move. The movement of the transition drive plate 706 causes the docking pullback to occur. The movement of rod 606 causes the docking pull-back rod 606 to slide within the merging bracket 5. The movement of the docking pull-back rod 606 pushes the push clamp 608 to move via the docking push plate 607, causing the push clamp 608 to drive the second pipe 2 to insert into the first pipe 1, thus achieving the function of automatic docking. Furthermore, if the docking pull-back rod 606 is still moving after docking, the docking push plate 607 is pulled, which in turn moves within the buffer groove 609 via the buffer slide rod 610, causing the buffer spring 611 to be stressed, providing a buffer distance for the docking push plate 607.

[0071] Furthermore, when the adapter slide shaft 708 moves downward, it drives the linkage pull-down bracket 804 to move, causing the linkage pull-down bracket 804 to drive the pull-down connecting rod 805 to move via the pull-down extension rod 807. The pull-down connecting rod 805 drives the rotating pull rod 803 to rotate via the linkage slide shaft 810. At the same time, the linkage slide shaft 810 moves within the linkage slide hole 809. The rotation of the rotating pull rod 803 drives the rotating pressure plate 802 to rotate via the drive shaft 811, causing the rotating pressure plate 802 to press against the top side of the second pipe 2 and interact with the first pipe. Alignment is achieved by aligning the second pipe 2 and the first pipe 1, thus facilitating full docking of the second pipe 2 and the first pipe 1. In addition, the rotation of the drive shaft 811 causes it to rotate within the drive groove 812, which in turn forces the reset torsion spring 813. Simultaneously, after the rotation of the pull rod 803, if the linkage pull bracket 804 continues to move, it moves within the pull extension groove 806 via the pull extension rod 807, which forces the pull extension spring 808 to stretch, providing a buffer space for the linkage pull bracket 804.
