Description

Technical Field

[0001] The present invention relates to the technical field of penstocks, and particularly to a penstock tile and a stiffening ring assembly construction system and method. Background Art

[0002] Penstocks are an important part of water conveyance structures in the development and construction of hydropower stations at home and abroad, and mainly appear in the form of a main penstock pipe combined with a stiffening ring. Penstocks have high strength and tightness, and can effectively bear the internal water pressure. Without increasing the wall thickness of the penstock, appropriately adding a stiffening ring outside the penstock can effectively improve the external pressure resistance of the penstock, with high economy. The penstock can also be constructed in cooperation with concrete lining to jointly bear the external pressure, further increasing the stability and water tightness of the lining structure, improving the service life, and making the formed tunnel shape more beautiful. Penstocks not only have the above excellent properties, but also have the characteristics of high plasticity and complex and diverse structural forms, and are increasingly used in various engineering projects.

[0042] Please refer to the appendix Figure 1 The appendix Figure 1 shows the structural schematic diagram of the penstock tile and stiffening ring assembly construction system provided by the embodiment of the present application. As can be seen from the appendix Figure 1 the penstock tile and stiffening ring assembly construction system provided by the embodiment of the present application includes an assembly platform 1, a plurality of support devices 2, a platform drive device 3, a climbing support 6, an inner automatic climbing device 7, an outer automatic climbing device 8, etc. Among them, a plurality of support devices 2 are evenly and symmetrically arranged below the assembly platform 1, and a platform drive device 3 is provided on one side of the support device 2, and the platform drive device 3 is connected to the assembly platform 1. Above the assembly platform 1, there are a penstock 4 and a stiffening ring 5, and the stiffening ring 5 is arranged outside the penstock 4. Climbing supports 6 are provided on both the inner and outer sides of the penstock 4, and an inner automatic climbing device 7 and an outer automatic climbing device 8 are respectively provided on the two climbing supports 6. The following describes the specific functions of each component and the relationship between the components in the embodiment of the present application in the form of specific embodiments in combination with the drawings.

[0043] The assembly platform 1 is a platform for realizing the assembly of the penstock 4 and the stiffening ring 5, and it can rotate around the center point of the assembly platform 1 to realize the assembly of the penstock 4 and the stiffening ring 5. Please refer to the appendix Figures 2 - 4 Among them, the appendix Figures 2 - 4 respectively shows the front view, top view and bottom view of the assembly platform provided by the embodiment of the present application. As can be seen from the appendix Figures 2 - 4 the assembly platform 1 provided by the embodiment of the present application includes a table top 101 and a first hydraulic jack 102 and a positioning baffle 103 arranged on the table top 101. Since the penstock 4 is cylindrical, the first hydraulic jack 102 and the positioning baffle 103 are both circumferentially distributed on the table top 101, and the positioning baffle 103 is located inside the first hydraulic jack 102.

[0044] When placing the penstock 4 on the tabletop 101, due to the different sizes of the penstock 4, the inner diameter contour line 107 and the outer diameter contour line 108 of the penstock 4 can be pre - laid out on the tabletop 101, and at the same time, the longitudinal joint position 109 when two steel pipe tiles are butt - jointed is marked. The positioning baffles 103 are evenly arranged according to the inner diameter contour line 107 of the penstock 4, and at the same time, the first hydraulic jacks 102 are evenly arranged according to the outer diameter contour line 108 of the penstock 4, so as to facilitate placing the penstock 4 between the first hydraulic jacks 102 and the positioning baffles 103, so that the positioning baffles 103 play a positioning role on the penstock 4. By controlling the ejection of the first hydraulic jacks 102, the first hydraulic jacks 102 are jacked against the penstock 4, and then the edges of the two steel pipe tiles for making the penstock 4 coincide with the inner diameter contour line 107 and the outer diameter contour line 108 and remain in a pressed state, thereby realizing the butt - joint of the penstock 4 by the butt - joint platform 1. Among them, the coincidence error is not more than 2 mm.

[0045] In addition, when there are two or more butt - joint seams of steel pipe tiles on the penstock 4, after one butt - joint seam is reinforced, the tabletop 101 needs to be rotated so that the next seam to be pressed and reinforced rotates between the inner automatic climbing device 7 and the outer automatic climbing device 8. Based on this, a guide rail base plate 104 is provided on the lower surface of the tabletop 101 in the embodiment of the present application. The guide rail base plate 104 is distributed in a circular shape on the tabletop 101, and a rack guide rail 105 is provided on the outer side of the guide rail base plate 104. The rack guide rail 105 meshes with the platform drive gear 301 in the platform drive device 3. Thus, when the platform drive gear 301 rotates, it can drive the rack guide rail 105 to rotate, and then make the tabletop 101 rotate, finally achieving the adjustment of the position of the penstock 4 between the inner automatic climbing device 7 and the outer automatic climbing device 8.

[0046] Furthermore, a stiffening plate 106 is also provided between the tabletop 101 and the guide rail base plate 104. The stiffening plate 106 is located inside the guide rail base plate 104 and is used to strengthen the support of the guide rail base plate 104.

[0047] The size of the butt - joint platform 1 in the embodiment of the present application can be adjusted according to the size of the penstock 4 to meet the manufacturing requirements of penstocks 4 of various sizes.

[0048] The support device 2 is a component for supporting the butt - joint platform 1, and it is located below the butt - joint platform 1. Please refer to the attached Figure 5 、 6 The attached Figure 5 、 6 show the front view and the bottom view of the support device and the platform drive device provided by the embodiment of the present application. From the attached Figure 5 、 6As can be seen, the support device 2 provided by the embodiment of the present application includes a support plate 201 and a support wheel frame 202 disposed on the support plate 201. The support plate 201 is fixedly connected to the concrete floor through embedded anchor hooks and fasteners, etc. Thus, the bearing capacity of the entire assembly platform 1 and the penstock 4 is transmitted to the concrete floor. The support wheel frame 202 is provided with support wheels 203, and the support wheels 203 are evenly distributed along the circumferential direction of the penstock 4. Since a plurality of support wheels 203 are evenly distributed in the circumferential direction of the penstock 4, sufficient support force can be provided to the penstock 4.

[0049] Furthermore, since the assembly platform 1 rotates under the action of the platform driving device 3, in order to facilitate the limitation of the rotation position of the assembly platform 1 and ensure the stability of the assembly platform 1 during rotation, a platform guiding wheel frame 204 is provided on the support plate 201 in the embodiment of the present application. The platform guiding wheel frame 204 is provided with platform guiding wheels 205, and the platform guiding wheels 205 are in contact with the guide rail base plate 104 in the assembly platform 1. Thus, under the limiting and guiding action of the platform guiding wheels 205, the assembly platform 1 can rotate within a certain range.

[0050] The platform driving device 3 is a component for driving the assembly platform 1 to rotate. As shown in the attached Figure 5 figure, the platform driving device 3 in the embodiment of the present application includes a platform driving gear 301 and a platform driving gear reducer 302 respectively located above and below the support plate 201, and the platform driving gear 301 and the platform driving gear reducer 302 are connected through a platform driving gear shaft 303. Thus, the entire platform driving device 3 is fixed on the support plate 201 through bolts and other fasteners. When the platform driving gear reducer 302 is powered on, the platform driving gear 301 can be driven to rotate through the driving of the platform driving gear shaft 303. Also, since the platform driving gear 301 meshes with the rack guide 105 in the assembly platform 1, the rotation of the platform driving gear 301 drives the rack guide 105 in the assembly platform 1 to rotate, and finally the tabletop 101 rotates.

[0051] The climbing bracket 6 is a device for facilitating the climbing of the inner automatic climbing device 7 and the outer automatic climbing device 8 along the length direction of the penstock 4. There are two climbing brackets 6 in total, which are respectively arranged on the inner and outer sides of the penstock 4. Please refer to the attached Figure 7 、 8 figure, and the attached Figure 7 、 8 respectively show the front view and top view of the climbing bracket provided by the embodiment of the present application. From the attached Figure 7 、 8As can be seen, the climbing support 6 provided by the embodiment of the present application includes a vertical support 601 and a diagonal support 602, and both the vertical support 601 and the diagonal support 602 are welded by steel sections and steel plates. A semi-circular straight guide rail 603 is provided on the outer side of the vertical support 601, and a climbing rack guide rail 604 is detachably provided on the inner side of the opposite sides of the vertical support 601. Among them, the semi-circular straight guide rail 603 is connected to the vertical support 601 by welding, and the climbing rack guide rail 604 is connected to the vertical support 601 by fasteners. A support reinforcement plate 605 is also provided on the vertical support 601 to improve the structural strength of the vertical support 601.

[0052] The climbing rack guide rail 604 meshes with the climbing gear 804 in the outer automatic climbing device 8, and the climbing rack guide rail 604 in another climbing support 6 meshes with the climbing gear 804 in the inner automatic climbing device 7. Therefore, the inner automatic climbing device 7 or the outer automatic climbing device 8 climbs relative to the climbing support 6. The climbing rack guide rail 604 can accurately control the up and down climbing accuracy of the inner automatic climbing device 7 and the outer automatic climbing device 8, ensure the accurate positioning of the installation position of the stiffening ring 5 by the inner automatic climbing device 7 and the outer automatic climbing device 8, and further control the installation accuracy of the stiffening ring 5.

[0053] In addition, when the climbing support 6 is installed, the distance between the inner automatic climbing device 7 and the wall of the penstock 4 should be less than the working stroke of the second hydraulic jack 802 to prevent the second hydraulic jack 802 from not touching the wall of the penstock 4.

[0054] Both the inner automatic climbing device 7 and the outer automatic climbing device 8 are components that climb along the length direction of the penstock 4. Their structures are the same and are independently controlled. Only the arrangement positions are different, that is, the inner automatic climbing device 7 is arranged on the climbing support 6 located inside the penstock 4, and the outer automatic climbing device 8 is arranged on the climbing support 6 located outside the penstock 4. The following describes the structures and functions of the inner automatic climbing device 7 and the outer automatic climbing device 8 with the outer automatic climbing device 8 as the description object.

[0055] Please refer to the attached Figure 9 、 10 . The attached Figure 9 、 10 respectively show the front view and the top view of the outer automatic climbing device 8. From the attached Figure 9 、 10 As can be seen, the outer automatic climbing device 8 provided by the embodiment of the present application includes a climbing machine frame 801 provided on the climbing support 6, and the climbing machine frame 801 is used to arrange all other components of the outer automatic climbing device 8. A second hydraulic jack 802 and a climbing gear reducer 803 are provided on one side of the climbing machine frame 801, and a climbing gear 804 and a climbing positioning guide wheel 805 are provided on the other side of the climbing machine frame 801.

[0056] Specifically, a pipe jacking joint 806 is connected to the end of the second hydraulic jack 802. This pipe jacking joint 806 is used to contact the pipe wall of the penstock 4, thereby facilitating the second hydraulic jack 802 to jack the penstock 4. Since the sizes of the penstocks 4 are different, the pipe wall curvatures are different and the sizes of the stiffening rings 5 are different. Therefore, the pipe jacking joint 806 can be custom-designed according to the external dimensions of the penstock 4 and the stiffening ring 5 and replaced according to the actual on-site requirements to ensure the assembly and installation effect of the penstock 4 and the stiffening ring 5.

[0057] The climbing gear reducer 803 is connected to the climbing gear 804 through a climbing gear shaft 807. Thus, under the action of the climbing gear reducer 803 and the climbing gear shaft 807, the climbing gear 804 rotates. Since the climbing gear 804 meshes with the climbing rack guide 604 in the climbing support 6 and the climbing rack guide 604 is fixed, the climbing gear 804 can rotate on the climbing rack guide 604 to realize the climbing of the external automatic climbing device 8 on the climbing support 6.

[0058] To ensure the stability and accuracy of the operation of the external automatic climbing device 8, a semi-circular straight guide groove 808 is provided on the climbing frame 801. This semi-circular straight guide groove 808 matches the semi-circular straight guide rail 603 in the climbing support 6, and the semi-circular straight guide rail 603 is engaged in the semi-circular straight guide groove 808. Thus, when the external automatic climbing device 8 moves up and down on the climbing support 6, under the interaction of the semi-circular straight guide rail 603 and the semi-circular straight guide groove 808, the climbing frame 801 can climb up and down along the fixed position of the vertical support 601. In addition, the setting of the climbing positioning guide wheel 805 can also ensure the smooth operation of the semi-circular straight guide rail 603.

[0059] Furthermore, a connecting plate 809 is provided below the second hydraulic jack 802. A stiffening ring support frame 9 is welded to the outside of the connecting plate 809. The stiffening ring support frame 9 supports the stiffening ring 5, thereby enabling the stiffening ring support frame 9 to play the role of supporting the stiffening ring 5. In addition, the stiffening ring support frame 9 has a contraction and folding function to avoid interference during the assembly and reinforcement of the penstock 4 tiles.

[0060] After the steel pipe tiles of the penstock 4 are compressed and fastened by the first hydraulic jack 102 and the positioning baffle 103, the inner automatic climbing device 7 and the outer automatic climbing device 8 are controlled by the climbing gear reducer 803 to run to the bottom of the docking seam of the two groups of steel pipe tiles. The inner automatic climbing device 7 is controlled to jack up the penstock 4 to the inner diameter contour line 107 on the assembly platform 1, and then the outer automatic climbing device 8 is controlled to apply pressure to the outer wall of the penstock 4 so that when the gap of the docking seam between the two groups of steel pipe tiles and the offset of the butt joint meet the relevant requirements, spot welding reinforcement is carried out. After welding is completed, after the inner automatic climbing device 7 and the outer automatic climbing device 8 climb up a certain distance, the docking seam is assembled and welded again until the docking seam between the two steel pipe tiles is completely welded. The distance that the inner automatic climbing device 7 and the outer automatic climbing device 8 climb up each time can be adjusted according to the actual situation. When the offset of the docking seam between the two steel pipe tiles is large, pipe jacking and reinforcement operations are carried out at this position.

[0061] After the docking seam between the two steel pipe tiles is welded, the platform driving gear 301 is controlled to rotate by the platform driving gear reducer 302, and then the rack guide 105 is controlled to rotate, and finally the rotation of the table top 101 is realized. During the rotation of the table top 101, when another docking seam rotates between the inner automatic climbing device 7 and the outer automatic climbing device 8, the platform driving gear reducer 302 stops rotating, and the inner automatic climbing device 7 and the outer automatic climbing device 8 fasten and weld this docking seam again.

[0062] After all the steel pipe tiles are welded to form the penstock 4, the stiffening ring 5 is installed on the penstock 4. Specifically, the inner automatic climbing device 7 and the outer automatic climbing device 8 are adjusted to the installation position of the stiffening ring 5. When the upper surface of the stiffening ring support frame 9 on the outer automatic climbing device 8 coincides with the lower surface position line of the installation position of the stiffening ring 5, the outer automatic climbing device 8 is fixed. At the same time, the inner automatic climbing device 7 is adjusted to the same elevation position. Then, the stiffening ring 5 is hoisted onto the stiffening ring support frame 9, and the outer edge of the stiffening ring 5 is jacked by the outer automatic climbing device 8 so that the inner surface of the stiffening ring 5 is closely attached to the outer wall of the penstock 4. When the gap between the inner surface of the stiffening ring 5 and the outer wall of the penstock 4 is not greater than 1 mm, welding reinforcement is carried out between the penstock 4 and the stiffening ring 5. After the installation of this stiffening ring 5 is completed, the assembly platform 1 is controlled to rotate, and then spot welding reinforcement of the stiffening ring 5 at the next position is carried out according to the above method until all the stiffening rings 5 are installed.

[0063] Based on the penstock tile and stiffening ring assembly construction system provided by the embodiment of the present application, the embodiment of the present application provides a method for assembling and constructing the penstock tile and the stiffening ring, and the method includes:

[0064] S01: Install and commission the above steel penstock tile and stiffening ring assembly construction system.

[0065] Install and fix devices such as the assembly platform 1, support device 2, and platform driving device 3 according to the requirements of the design drawings, and connect the power supply for commissioning.

[0066] S02: Hoist the steel penstock tile to the preset position on the assembly platform.

[0067] Hoist the steel penstock tile of the steel penstock 4 to the preset position on the assembly platform 1, and this preset position is determined according to the size of the steel penstock 4. Uniformly arrange positioning baffles 103 according to the inner diameter contour line 107 of the steel penstock 4, and at the same time, uniformly arrange the first hydraulic jacks 102 according to the outer diameter contour line 108 of the steel penstock 4, so as to place the steel penstock 4 between the first hydraulic jacks 102 and the positioning baffles 103, so that the positioning baffles 103 play a positioning role on the steel penstock 4. By controlling the ejection of the first hydraulic jacks 102, the first hydraulic jacks 102 are jacked against the steel penstock 4, and then the edges of the two steel penstock tiles for making the steel penstock 4 coincide with the inner diameter contour line 107 and the outer diameter contour line 108 and remain in a compressed state.

[0068] S03: Under the action of the climbing bracket, the inner automatic climbing device and the outer automatic climbing device press and weld the butt weld of the steel penstock tile.

[0069] When the first hydraulic jacks 102 and the positioning baffles 103 press and fasten the steel penstock tiles of the steel penstock 4, control the inner automatic climbing device 7 and the outer automatic climbing device 8 to run to the bottom of the butt joint of the two steel penstock tiles through the climbing gear reducer 803. Control the inner automatic climbing device 7 to jack the steel penstock 4 to the inner diameter contour line 107 on the assembly platform 1, and then control the outer automatic climbing device 8 to apply pressure to the outer wall of the steel penstock 4, so that when the butt joint gap and the alignment offset of the two steel penstock tiles meet the relevant requirements, carry out spot welding reinforcement. After welding is completed, control the inner automatic climbing device 7 and the outer automatic climbing device 8 to climb up a certain distance, and then butt joint and weld again until the butt joint between the two steel penstock tiles is completely welded.

[0070] S04: The platform driving device drives the assembly platform to rotate, so that the inner automatic climbing device and the outer automatic climbing device press and weld the unwelded butt weld of the steel penstock tile.

[0071] After the butt welding of the circumferential joints between two steel pipe tiles is completed, the platform driving gear reducer 302 is used to control the rotation of the platform driving gear 301, and then the rack guide 105 is controlled to rotate, finally realizing the rotation of the tabletop 101. During the rotation of the tabletop 101, when another circumferential joint rotates between the inner automatic climbing device 7 and the outer automatic climbing device 8, the platform driving gear reducer 302 stops rotating, and the inner automatic climbing device 7 and the outer automatic climbing device 8 fasten and weld this circumferential joint again.

[0072] S05: After the butt joint of the penstock tiles is completed, adjust the inner automatic climbing device and the outer automatic climbing device to the stiffening ring butt joint position.
