[0001] This invention relates to the field of mechanical equipment technology, specifically to a circular support fixture and a circular assembly device. Background Technology

[0002] In the manufacturing process of ultra-large diameter circular pipe structures (such as underground tunnel pipelines and large gas storage pipelines), due to the large diameter of the pipe and the limited underground transport channels, it is impossible to directly transport the pipe to the designated installation location in the construction area. It is necessary to first disassemble the pipe into multiple segments, then transport these segments to a pipe assembly machine in the construction area. The assembly machine then uses this machine to assemble the segments into a complete pipe, which is finally transported to the designated installation location.

[0003] During the assembly and installation of segmented circular tubes, the large diameter and heavy weight of the tubes can easily lead to deformation. Therefore, support is required. Traditional methods of support often involve temporary welded supports or simple jacks. However, these methods suffer from low adjustment precision and difficulty in disassembly and assembly, resulting in inconsistent roundness and overall dimensional accuracy of the tubes, thus affecting the overall project quality. Summary of the Invention

Each support mechanism includes a support rod and an adjusting component. One end of the support rod is connected to the mounting mechanism, and the other end is equipped with an adjusting component that can extend and retract along the axial direction of the support rod.

[0006] Beneficial effects: The length of the support mechanism can be precisely adjusted using the adjusting components, controlling the roundness of the overall circular tube. This facilitates precise adjustment of the tube's roundness, increases the overall dimensional accuracy of the tube, and improves the overall quality of the construction project.

[0008] Beneficial effects: Construction workers can quickly install and position the support mechanism using the scale lines, and can also quickly and accurately adjust the roundness of the pipe.

[0009] In one alternative embodiment, the support mechanism further includes a pad located at the end of the adjuster away from the support rod.

[0010] Beneficial effects: The pad increases the contact area and force-bearing area with the round pipe, enabling the entire round support fixture to provide better support to the round pipe.

[0011] In one alternative embodiment, the adjusting element is a hydraulic jack, the mounting end of which is connected to the end of the support rod away from the mounting mechanism, and the driving end of which is connected to a pad.

[0012] Beneficial effects: The lifting action of the hydraulic jack allows for fine-tuning of the support rod length, and in conjunction with the pad block, ensures the stability of the support rod and the radius of the entire circular support fixture throughout the construction process.

[0013] In one alternative embodiment, the mounting mechanism includes a mounting base and a plurality of connectors, the plurality of connectors being circumferentially spaced around the mounting base, with one end of each connector connected to the mounting base and the other end connected to the end of the support rod away from the adjusting member.

[0014] In one alternative embodiment, the mounting base includes a connecting plate and a sleeve, the connecting plate being disposed at one end of the sleeve, and one end of the connector being connected to the connecting plate.

[0015] Beneficial effects: The sleeve increases the contact area between the mounting base and the output shaft, improving the stability of the mounting base fixed on the output shaft.

[0016] In one alternative embodiment, the end of the connector away from the mounting base is provided with an external thread, and the end of the support rod away from the adjusting member is provided with an internal thread, and the support rod is threadedly connected to the connector.

[0017] Beneficial effects: Construction workers can directly tighten the support rods to the connectors by threading them, and can assemble the device even without hoisting equipment, thus improving the versatility of the entire device.

[0018] Secondly, the present invention also provides a circular assembly device, including the above-mentioned circular assembly support fixture and a circular assembly machine. The circular assembly machine includes a main unit and a base. The main unit is disposed on the base, and the circular assembly support fixture is disposed on the output shaft of the main unit.

[0019] Beneficial effects: The combination of the rounding machine and the rounding support fixture can complete the process of assembling segmented rounds, and the rounding support fixture can increase the overall roundness and accuracy of the round tube, thereby improving the quality of the entire construction project.

[0020] In one optional embodiment, the assembly device further includes an anti-detachment device disposed at one end of the output shaft. The anti-detachment device has an anti-detachment state in which it abuts against the side of the mounting mechanism near the end of the output shaft, and a separation state in which it separates from the side of the mounting mechanism near the end of the output shaft.

[0021] Beneficial effect: The anti-drop device prevents the circular support fixture from detaching from the output shaft due to vibration or rotation.

[0022] In one optional embodiment, the anti-detachment device includes a guide mechanism, a clamping mechanism, and a drive component. One end of the output shaft is provided with an installation sleeve, which has an installation cavity. Multiple limiting grooves are spaced apart around the installation cavity on the installation sleeve. The guide mechanism includes an end plate and a guide rod. The inner wall of the installation cavity away from the output shaft is a first end face, and the end plate is disposed on the first end face. One end of the guide rod is connected to the end plate.

The middle part of the locking member is hinged to the hinge seat, and one end is hinged to the other end of the follower. The fixed end of the drive component is connected to the output shaft, and the driving end is connected to the movable seat. When the anti-detachment device is in the anti-detachment state, the other end of the locking member extends out of the limiting groove and abuts against the installation mechanism. When the anti-detachment device is in the disengaged state, the other end of the locking member retracts into the installation cavity.

[0023] Beneficial effect: Prevents axial movement and accidental detachment of the circular support fixture. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the manufacturing process of ultra-large diameter circular pipe structures (such as underground tunnel pipelines and large gas storage pipelines), due to the large diameter of the pipe and the limited underground transport channels, it is impossible to directly transport the pipe to the designated installation location in the construction area. It is necessary to first disassemble the pipe into multiple segments, then transport these segments to a pipe assembly machine in the construction area. The assembly machine then uses this machine to assemble the segments into a complete pipe, which is finally transported to the designated installation location.

[0029] During the assembly and installation of segmented circular tubes, the large diameter and heavy weight of the tubes can easily lead to deformation. Therefore, support is required. Current technologies often employ temporary welded supports or simple jacks for this purpose. However, these methods suffer from low adjustment precision and difficulty in disassembly, resulting in inconsistent roundness and overall dimensional accuracy of the tubes, thus affecting the overall project quality.

[0030] like Figure 1 , Figure 2 , Figure 3As shown, an embodiment of the present invention provides a circular support fixture, including an installation mechanism 1 and multiple sets of support mechanisms 2, which are arranged circumferentially around the installation mechanism 1. Each support mechanism 2 includes a support rod 201 and an adjusting member 202. One end of the support rod 201 is connected to the installation mechanism 1, and the other end is provided with the adjusting member 202, which can extend and retract axially along the support rod 201.

[0031] The mounting mechanism 1 has a tooling interface at its center that mates with the output shaft 5 of the rounding machine. This tooling interface allows the mounting mechanism 1 to be detachably mounted on the output shaft 5 of the rounding machine and to rotate coaxially with the output shaft 5. The mounting mechanism 1 is the main load-bearing and support structure of the rounding support tooling. It is integrally welded from high-strength steel to ensure the strength of the overall structure.

[0032] The mounting mechanism 1 has multiple connection ports at its end, and multiple sets of support mechanisms 2 are arranged circumferentially around the mounting mechanism 1. The end of each set of support mechanisms 2 is detachably connected to the connection port of the mounting mechanism 1, facilitating the disassembly and installation of the circular support fixture. The support mechanism 2 includes a support rod 201 and an adjusting component 202, which can adjust the number of support mechanisms 2 according to different circular tube diameters. The adjusting component 202 can precisely adjust the diameter of the circular support fixture, facilitating quick positioning during the installation of the support mechanism 2 and ensuring the roundness of the overall circular tube.

[0033] The hoisting equipment first lifts the installation mechanism 1 of the circular assembly support fixture above the circular assembly machine, then slowly lowers it. The fixture interface of installation mechanism 1 is then fitted onto the output shaft 5 of the circular assembly machine, fixing installation mechanism 1 in place. Installation mechanism 1 rotates coaxially with the output shaft 5 of the circular assembly machine. While the circular assembly machine assembles the segmented circular sections, the support mechanism 2 is installed. The length of support mechanism 2 is precisely adjusted via the telescoping mechanism 202 to control the roundness of the overall circular tube. After all the segmented circular sections are assembled and welded into a circular tube, support mechanism 2 and installation mechanism 1 are removed, completing the entire construction process. The circular assembly support fixture facilitates precise adjustment of the roundness of the circular tube, increases the overall dimensional accuracy of the circular tube, improves the overall quality of the construction project, and its easy disassembly reduces the difficulty and labor intensity for workers.

[0034] Optional, such as Figure 4 As shown, the adjusting member 202 has scale lines along its extension and retraction direction.

[0035] The side of the adjusting component 202 is provided with scale lines, which allow construction personnel to quickly install and position the support mechanism 2, and also to quickly and accurately adjust the roundness of the tube.

[0036] Optional, such as Figure 3 , Figure 4As shown, the support mechanism 2 also includes a pad 203, which is disposed at the end of the adjusting member 202 away from the support rod 201.

[0037] The pad 203 is fixedly connected to the end of the hydraulic structure. The pad 203 is square and is used to fine-tune and finally lock the overall height of the support mechanism 2. As a component that directly contacts the round tube, the pad 203 can be made of flexible materials such as silicone. Flexible materials can better conform to the round tube, increase the contact area and the force-bearing area, and enable the entire round support fixture to better provide support force to the round tube.

[0038] Furthermore, such as Figure 3 , Figure 4 As shown, the adjusting component 202 is a hydraulic jack. The mounting end of the hydraulic jack is connected to the end of the support rod 201 away from the mounting mechanism 1, and its driving end is connected to the pad block 203.

[0039] The length of the support rod 201 is finely adjusted by the lifting action of the hydraulic jack, and it works in conjunction with the pad block 203 to ensure the stability of the support rod 201 and the radius of the entire circular support fixture throughout the construction process.

[0040] Optional, such as Figure 3 , Figure 4 As shown, the support mechanism 2 also includes a pad 203, which is disposed at the end of the adjusting member 202 away from the support rod 201.

[0041] The pad 203 is fixedly connected to the end of the hydraulic structure. The pad 203 is square and is used to fine-tune and finally lock the overall height of the support mechanism 2. As a component that directly contacts the round tube, the pad 203 can be made of flexible materials such as silicone. Flexible materials can better conform to the round tube, increase the contact area and the force-bearing area, and enable the entire round support fixture to better provide support force to the round tube.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the installation mechanism 1 includes: a mounting base 101 and a plurality of connectors 102. The plurality of connectors 102 are arranged circumferentially around the mounting base 101, and one end of the connector 102 is connected to the mounting base, and the other end is connected to the end of the support rod 201 away from the adjusting member 202.

[0043] Mounting base 101 is integrally welded with multiple connecting parts 102. Mounting base 101 is disc-shaped with multiple mounting holes circumferentially provided. The mounting mechanism 1 is fixedly mounted on the output shaft 5 through the multiple mounting holes by threads. A tooling interface is provided in the middle of mounting base 101 to connect with the output shaft 5 of the rounding machine. Mounting base 101 is sleeved on the output shaft 5 of the rounding machine and fixedly connected to the output shaft 5 through the mounting holes, so that mounting base 101 and output shaft 5 can rotate coaxially.

[0044] The mounting base 101 is welded with multiple connectors 102, and the number of connectors 102 can be adjusted according to the diameter and weight of different round tubes to match the diameter and weight of the round tubes.

[0045] Optional, such as Figure 1 , Figure 2 , Figure 3 As shown, the mounting base 101 includes a connecting plate 1011 and a sleeve 1012. The connecting plate 1011 is disposed at one end of the sleeve 1012, and one end of the connector 102 is connected to the connecting plate 1011.

[0046] The connecting plate 1011 has multiple mounting holes spaced around its circumference. The connecting plate 1011 has a tooling interface in the middle that is connected to the output shaft 5 of the rounding machine. The inner diameter of the sleeve 1012 is the same as the diameter of the tooling interface. The sleeve 1012 is integrally welded to the connecting plate 1011. The sleeve 1012 increases the contact area between the mounting base 101 and the output shaft 5, and improves the stability of the mounting base 101 fixed on the output shaft 5.

[0047] Furthermore, such as Figure 2 , Figure 3 As shown, the end of the connector 102 away from the mounting base 101 is provided with an external thread, and the end of the support rod 201 away from the adjusting member 202 is provided with an internal thread. The support rod 201 is threadedly connected to the connector 102.

[0048] The diameter of the support rod 201 is the same as that of the connector 102, and they are coaxially connected. The end of the connector 102 furthest from the mounting base 101 has an external thread, and the end has a tapered guide. The tapered guide facilitates the positioning and axial alignment of the support rod 201 on the connector, reducing the difficulty for workers in aligning the connector 102 and the support rod 201, and making installation of the connector 102 and the support rod 201 easier. In one embodiment of the invention, the weight of a single support rod 201 is approximately 15 kg, allowing for direct manual tightening of the support rod 201 onto the connector 102. This enables assembly even without lifting equipment, improving the applicability of the entire device.

[0049] According to an embodiment of the present invention, in another aspect, a circular assembly device is also provided, such as... Figure 5 , Figure 6 As shown, the circular assembly equipment includes the aforementioned circular assembly support fixture and circular assembly machine. The circular assembly machine includes a main unit 3 and a base 4. The main unit 3 is mounted on the base 4, and the circular assembly support fixture is mounted on the output shaft 5 of the main unit 3.

[0050] In the manufacturing process of ultra-large diameter circular pipe structures (such as underground tunnel pipelines and large gas storage pipelines), due to the large diameter of the circular pipe and the limited underground transportation channels, it is impossible to directly transport the circular pipe to the designated installation location in the construction area. It is necessary to first disassemble the circular pipe into multiple segments, then transport these segments to a circular assembly machine in the construction area via a transportation channel. The circular assembly machine then assembles these segments into a circular pipe, which is finally transported to the designated installation location. The circular assembly support fixture is mounted on the output shaft 5 of the main unit 3 of the circular assembly machine and rotates coaxially with the output shaft 5. While assembling each segment, the circular assembly machine installs corresponding support rods 201 to ensure the roundness and precision standards of the entire circular pipe. The circular assembly machine and the circular assembly support fixture work together to complete the construction process of assembling the segmented circular pipes into a circular pipe.

[0051] Optional, such as Figure 7 As shown, the assembly equipment also includes an anti-detachment device 6 disposed at one end of the output shaft 5. The anti-detachment device 6 has an anti-detachment state in which it abuts against the side of the mounting mechanism 1 near the end of the output shaft 5, and a separation state in which it separates from the side of the mounting mechanism 1 near the end of the output shaft 5.

[0052] After fixing the round support fixture onto the output shaft 5 of the rounding machine, activate the anti-detachment device 6 on the output shaft 5. The anti-detachment device 6 will lock the round support fixture onto the output shaft 5 to prevent the round support fixture from detaching from the output shaft 5 due to vibration or rotation.

[0053] Furthermore, such as Figure 7 , Figure 8 , Figure 9As shown, the anti-drop device 6 includes a guide mechanism 601, a clamping mechanism 602, and a driving component 603. One end of the output shaft 5 is provided with an installation sleeve 1012, which has an installation cavity. Multiple limiting grooves 7 are spaced apart around the installation cavity on the installation sleeve 1012. The guide mechanism 601 includes an end plate 6011 and a guide rod 6012. The inner wall of the installation cavity on the side away from the output shaft 5 is the first end face, and the end plate 6011 is disposed on the first end face. One end of the guide rod 6012 is connected to the end plate 6011. The clamping mechanism 602 includes a movable seat 6021, a follower 6022, a clamping component 6023, and a hinge seat 6024. The movable seat 6021 is slidably mounted... Placed on the guide rod 6012, multiple follower members 6022 are arranged circumferentially around the movable seat 6021. One end of the follower member 6022 is hinged to the movable seat 6021. A hinge seat 6024 is provided on the first end face near each limiting groove 7. The middle part of the snap-fit ​​member 6023 is hinged to the hinge seat 6024, and one end is hinged to the other end of the follower member 6022. The fixed end of the drive member 603 is connected to the output shaft 5, and the drive end is connected to the movable seat 6021. When the anti-detachment device 6 is in the anti-detachment state, the other end of the snap-fit ​​member 6023 extends out of the limiting groove 7 and abuts against the mounting mechanism 1. When the anti-detachment device 6 is in the disengaged state, the other end of the snap-fit ​​member 6023 retracts into the mounting cavity.

[0054] An end plate 6011 is fixedly mounted on the end of the output shaft 5. The end plate 6011 is a circular sheet metal block with three sets of mounting holes spaced circumferentially. Each set of mounting holes includes four small holes. A hinge seat 6024 is fixedly mounted on the end plate 6011 through these mounting holes. A guide rod 6012 is fixedly connected to the end of the end plate 6011 facing the output shaft 5. A movable seat 6021 is sleeved on the guide rod 6012 and moves axially along the guide rod 6012 under the drive of the drive member 603. Multiple follower members 6022 are spaced circumferentially on the movable seat 6021 and are hinged to it. One end of each follower member 6022 is hinged to the movable seat 6021, and the other end is hinged to a snap-fit ​​member 6023. The middle part of the snap-fit ​​member 6023 is hinged to the hinge seat 6024. A number of limiting grooves 7, the same as the number of locking members 6023, are provided circumferentially at the relative positions of the mounting sleeve 1012 and the locking member 6023. When the anti-detachment device 6 is in the anti-detachment state, the locking member 6023 extends out of the limiting groove 7 and abuts against the mounting mechanism 1 to prevent the mounting mechanism 1 from detaching from the output shaft 5. When the anti-detachment device 6 is in the disengaged state, the locking member 6023 retracts into the mounting cavity, making it easy to remove the circular support fixture from the output shaft 5.

[0055] When the mounting mechanism 1 is hoisted onto the output shaft 5, the drive unit 603 is activated. The drive unit 603 pushes the movable seat 6021 to move axially along the guide rod 6012 toward the end plate 6011. The movable seat 6021 drives the follower 6022 to rotate. The follower 6022 synchronously drives the locking piece 6023 to rotate around the hinge point between the hinge seat 6024 and the locking piece 6023. When one end of the locking piece 6023 rotates outside the limiting groove 7, the locking piece 6023 abuts against the mounting mechanism 1 and locks it onto the output shaft 5, preventing the rounding support fixture from falling off the output shaft 5 during the rounding process. After the rounding equipment completes the rounding work, the drive unit 603 pushes the movable seat 6021 to move axially along the guide rod 6012 toward the output shaft 5. The movable seat 6021 drives the follower 6022 and the locking piece 6023 to rotate, and one end of the locking piece 6023 retracts from outside the limiting groove 7 into the mounting cavity. At this point, the circular support fixture and the accompanying circular pipe are safely lifted away.

[0056] Furthermore, the installation and operation processes of the assembly equipment and the assembly support fixture are described. Within the working area of ​​the assembly equipment, the hoisting equipment lifts the installation mechanism 1 above the assembly equipment and lowers it down. The center of the sleeve 1012 is aligned with the output shaft 5 of the assembly equipment, and the installation mechanism 1 is fixed to the output shaft 5. The anti-falling device 6 is activated to lock the installation mechanism 1 onto the output shaft 5, preventing axial movement and accidental fall of the installation mechanism 1.

[0057] Begin hoisting the segmented circles and perform initial assembly and comparison around the mounting mechanism 1. After assembling the first and second segmented circles, simultaneously install the corresponding support mechanisms 2 onto the mounting mechanism 1. Align the external thread of the connector 102 with the internal thread of the support rod 201, insert and tighten to complete the installation of the support mechanism 2.

[0058] As the segmented circles are installed one by one, the remaining support mechanisms 2 are installed onto the installation mechanism 1. Then, according to the preset radius of the circular tube, the adjusting parts 202 of each support mechanism 2 are adjusted. The construction personnel operate the hydraulic jack through the scale markings on the adjusting parts 202 to lift all the support mechanisms 2 to the preset radius position, and make the final fine adjustment and lock through the pad block 203.

[0059] Continue assembling the remaining segmented circles until all segments are completely closed to form a complete circular tube. Throughout the process, the construction personnel can fine-tune the length of the support mechanism 2 according to the variations in the individual segmented circles to eliminate misalignments and gaps between them. After all segmented circles are spot-welded and fixed, re-check the connection status of all support mechanisms 2 and the locking status of the jacks to ensure the stability of the entire circular assembly support fixture during the welding process.

[0060] After the assembly and welding of the round pipe are completed, the entire round pipe and the assembly support fixture are lifted off the round pipe assembly machine together. Before lifting, ensure that the telescopic part of the anti-falling device 6 is retracted into the output shaft 5. Then, the round pipe and the entire set of assembly support fixtures are transported to the installation position by a transport trolley.

[0061] After the circular pipe is installed and welded, the pad 203 and jack are loosened and removed from top to bottom using hoisting equipment. The support mechanism 2 is then removed from the installation mechanism 1, ensuring that the anti-falling device 6 is in a disengaged state. The installation mechanism 1 is then lifted out of the circular pipe using hoisting equipment. After all disassembly is completed, all parts are inspected, and the components are transported by a transport trolley to the circular pipe assembly machine for the next circular pipe assembly operation, achieving cyclical reuse.

[0062] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
