Detailed Description
Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating a construction system with a pressure steel pipe tile and a stiffener ring set according to an embodiment of the present disclosure. As can be seen from fig. 1, the pressure steel pipe tile and stiffener ring set provided in the embodiment of the present application includes a set platform 1, a plurality of supporting devices 2, a platform driving device 3, a climbing support 6, an inner automatic climbing device 7, an outer automatic climbing device 8, and the like, wherein the plurality of supporting devices 2 are uniformly and symmetrically disposed below the set platform 1, the platform driving device 3 is disposed on one side of the supporting devices 2, and the platform driving device 3 is connected to the set platform 1. The upper part of the assembly platform 1 is provided with a pressure steel pipe 4 and a stiffening ring 5, and the stiffening ring 5 is arranged on the outer side of the pressure steel pipe 4. The inner side and the outer side of the pressure steel pipe 4 are both provided with climbing brackets 6, and the two climbing brackets 6 are respectively provided with an inner automatic climbing device 7 and an outer automatic climbing device 8. The specific functions of the components and the functional relationships among the components in the embodiments of the present application are described below in the form of specific embodiments with reference to the accompanying drawings.
The assembly platform 1 is a platform for realizing assembly of the pressure steel pipe 4 and the stiffening ring 5, and can rotate by taking the central point of the assembly platform 1 as the center so as to realize assembly of the pressure steel pipe 4 and the stiffening ring 5. Referring to fig. 2-4, fig. 2-4 respectively show a front view, a top view and a bottom view of the pairing platform provided by the embodiment of the present application. As can be seen from fig. 2 to 4, the pairing platform 1 provided in the embodiment of the present application includes a table top 101, and a first hydraulic jack 102 and a positioning baffle 103 disposed on the table top 101. Since the pressure steel pipe 4 is cylindrical, the first hydraulic jacks 102 and the positioning baffle 103 are circumferentially distributed on the table top 101, and the positioning baffle 103 is located inside the first hydraulic jacks 102.
When the penstock 4 is placed on the table top 101, the penstock 4 has different sizes, so that the inner diameter contour 107 and the outer diameter contour 108 of the penstock 4 can be set out on the table top 101 in advance, and the longitudinal seam position 109 of the two steel pipe tile group pairs can be marked at the same time. The positioning baffle plates 103 are uniformly arranged according to the inner diameter contour line 107 of the pressure steel pipe 4, and the first hydraulic jacks 102 are uniformly arranged according to the outer diameter contour line 108 of the pressure steel pipe 4, so that the pressure steel pipe 4 is placed between the first hydraulic jacks 102 and the positioning baffle plates 103, and the positioning baffle plates 103 can position the pressure steel pipe 4. The first hydraulic jack 102 is jacked on the pressure steel pipe 4 by controlling the ejection of the first hydraulic jack 102, so that the edges of the two steel pipe tiles for manufacturing the pressure steel pipe 4 are coincided with the inner diameter contour line 107 and the outer diameter contour line 108, and the pressing state is kept, and therefore the assembly of the assembly platform 1 to the pressure steel pipe 4 is achieved. Wherein the superposition error is not more than 2 mm.
In addition, when the pressure steel pipe 4 has 2 or more steel pipe tile assembly joints, after one assembly joint is reinforced, the table top 101 needs to be rotated, so that the next joint needing to be pressed and reinforced is rotated to a position between the inner automatic climbing device 7 and the outer automatic climbing device 8. On the basis, the lower surface of the table top 101 in the embodiment of the present application is provided with the guide rail base plate 104, the guide rail base plate 104 is circumferentially distributed on the table top 101, and the rack guide rail 105 is arranged on the outer side of the guide rail base plate 104. The rack guide rail 105 is meshed with the platform driving gear 301 in the platform driving device 3, so that when the platform driving gear 301 rotates, the rack guide rail 105 can be driven to rotate, the table top 101 is further driven to rotate, and finally the position of the pressure steel pipe 4 between the inner automatic climbing device 7 and the outer automatic climbing device 8 is adjusted.
Further, a stiffening plate 106 is further arranged between the table top 101 and the guide rail base plate 104, and the stiffening plate 106 is located on the inner side of the guide rail base plate 104 and is used for strengthening and supporting the guide rail base plate 104.
The size of the platform 1 can be adjusted according to the size of the pressure steel pipe 4 by the group in the embodiment of the application, so that the manufacturing requirements of the pressure steel pipes 4 with various sizes are met.
The supporting device 2 is a part for supporting the pairing platform 1, and is located below the pairing platform 1. Referring to fig. 5 and 6, fig. 5 and 6 show front and bottom views of a supporting device and a platform driving device provided in an embodiment of the present application. As shown in fig. 5 and 6, the supporting device 2 provided in the embodiment of the present application includes a supporting plate 201 and a supporting wheel frame 202 disposed on the supporting plate 201. The support plate 201 is fixedly connected with the concrete floor through pre-buried anchor hooks, fasteners and the like, and therefore the bearing capacity of the whole assembly platform 1 and the pressure steel pipe 4 is transmitted to the concrete floor. The supporting wheel frame 202 is provided with supporting wheels 203, and the supporting wheels 203 are uniformly distributed along the circumferential direction of the penstock 4. Since the plurality of support wheels 203 are evenly distributed in the circumferential direction of the pressure steel pipe 4, a sufficient supporting force can be given to the pressure steel pipe 4.
Further, since the group is rotated by the platform driving device 3 with respect to the platform 1, in order to facilitate the limitation of the rotational position of the group with respect to the platform 1 and ensure the stability of the group with respect to the rotation of the platform 1, the supporting plate 201 in the embodiment of the present application is provided with a platform guiding wheel frame 204, the platform guiding wheel frame 204 is provided with a platform guiding wheel 205, and the platform guiding wheel 205 is in contact with the guiding rail base plate 104 in the group with respect to the platform 1. Thus, the group can rotate within a certain range with the limited guiding action of the platform guide wheels 205 with respect to the platform 1.
The platform driving device 3 is a component for driving the group to rotate the platform 1. As shown in fig. 5, 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 supporting plate 201, and the platform driving gear 301 and the platform driving gear reducer 302 are connected by a platform driving gear shaft 303. Thereby, the entire platform driving device 3 is fixed to the support plate 201 by a fastener such as a bolt. When the platform driving gear reducer 302 is electrically operated, the platform driving gear 301 can be rotated by the driving of the platform driving gear shaft 303. And because the platform driving gear 301 is meshed with the rack guide rail 105 in the pairing platform 1, the rotation of the platform driving gear 301 drives the rack guide rail 105 in the pairing platform 1 to rotate, and finally the table top 101 rotates.
The climbing bracket 6 is a device which is convenient for the inner automatic climbing device 7 and the outer automatic climbing device 8 to climb along the length direction of the pressure steel pipe 4. The climbing supports 6 are provided with two in total and are respectively arranged at the inner side and the outer side of the pressure steel pipe 4. Referring to fig. 7 and 8, fig. 7 and 8 show a front view and a top view, respectively, of a climbing support provided by an embodiment of the present application. As shown in fig. 7 and 8, 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 formed by welding steel sections and steel plates. The outside of the vertical support 601 is provided with a semicircular arc straight guide rail 603, the inside of the opposite side surface of the vertical support 601 is detachably provided with a climbing rack guide rail 604, wherein the semicircular arc straight guide rail 603 is connected with the vertical support 601 in a welding manner, and the climbing rack guide rail 604 is connected with the vertical support 601 through a fastener. A support reinforcing plate 605 is further provided on the vertical support 601 to improve the structural strength of the vertical support 601.
The climbing rack rail 604 meshes with the climbing gear 804 in the outer climbing device 8, and the climbing rack rail 604 in the other climbing support 6 meshes with the climbing gear 804 in the inner climbing device 7, so that the inner climbing device 7 or the outer climbing device 8 climbs relative to the climbing support 6. The climbing rack guide rail 604 can accurately control the up-and-down climbing precision of the inner automatic climbing device 7 and the outer automatic climbing device 8, ensure that the inner automatic climbing device 7 and the outer automatic climbing device 8 accurately position the installation position of the stiffening ring 5, and further control the installation precision of the stiffening ring 5.
In addition, when the climbing support 6 is installed, the distance between the inner automatic climbing device 7 and the pipe wall of the pressure steel pipe 4 is smaller than the working stroke of the second hydraulic jack 802, so as to prevent the second hydraulic jack 802 from touching the pipe wall of the pressure steel pipe 4.
The inner automatic climbing device 7 and the outer automatic climbing device 8 are both climbing parts along the length direction of the pressure steel pipe 4, the structures of the inner automatic climbing device 7 and the outer automatic climbing device 8 are the same, the inner automatic climbing device and the outer automatic climbing device are respectively and independently controlled, and only the arrangement positions are different, namely the inner automatic climbing device 7 is arranged on the climbing support 6 positioned on the inner side of the pressure steel pipe 4, and the outer automatic climbing device 8 is arranged on the climbing support 6 positioned on the outer side of the pressure steel pipe 4. The following description of the structure and the function of the internal automatic climbing device 7 and the external automatic climbing device 8 is given for the external automatic climbing device 8.
Referring to fig. 9 and 10, fig. 9 and 10 show a front view and a top view, respectively, of the external automatic climbing device 8. As can be seen from fig. 9 and 10, the external automatic climbing device 8 provided by the embodiment of the present application includes a climbing frame 801 disposed on the climbing support 6, and the climbing frame 801 is used for disposing all other components of the external automatic climbing device 8. A second hydraulic jack 802 and a climbing gear reducer 803 are arranged on one side of the climbing rack 801, and a climbing gear 804 and a climbing positioning guide wheel 805 are arranged on the other side of the climbing rack 801.
Specifically, the end of the second hydraulic jack 802 is connected to a top pipe joint 806, and the top pipe joint 806 is used for contacting with the pipe wall of the pressure steel pipe 4, so that the second hydraulic jack 802 can press the pressure steel pipe 4 conveniently. Because the size of the pressure steel pipe 4 is different, the radian of the pipe wall is different, and the size of the stiffening ring 5 is different, so that the pipe jacking joint 806 can be customized and designed according to the overall dimensions of the pressure steel pipe 4 and the stiffening ring 5 and can be replaced according to the actual requirements on site, so as to ensure the assembly and installation effect of the pressure steel pipe 4 and the stiffening ring 5.
The climbing gear reducer 803 and the climbing gear 804 are connected to each other via a climbing gear shaft 807, and the climbing gear 804 is rotated by the climbing gear reducer 803 and the climbing gear shaft 807. Since the climbing gear 804 is engaged with the climbing rack rail 604 in the climbing support 6 and the climbing rack rail 604 is fixed, the climbing gear 804 can rotate on the climbing rack rail 604, so that the automatic climbing device 8 can climb on the climbing support 6.
In order to ensure the stability and the accuracy of the operation of the external automatic climbing device 8, a semicircular arc straight guide groove 808 is arranged on the climbing rack 801, the semicircular arc straight guide groove 808 is matched with a semicircular arc straight guide rail 603 in the climbing bracket 6, and the semicircular arc straight guide rail 603 is clamped in the semicircular arc straight guide groove 808. Thus, when the outer automatic climbing device 8 moves up and down on the climbing support 6, the climbing frame 801 can climb up and down along the fixed position of the vertical support 601 by the interaction between the semicircular arc straight guide rail 603 and the semicircular arc straight guide groove 808. In addition, the setting of the climbing positioning guide wheel 805 can also ensure the running stability of the semicircular arc straight guide rail 603.
Further, a connecting plate 809 is arranged below the second hydraulic jack 802, a stiffening ring support frame 9 is welded on the outer side of the connecting plate 809, and the stiffening ring support frame 9 supports the stiffening ring 5, so that the stiffening ring support frame 9 can support the stiffening ring 5. In addition, the stiffening ring support frame 9 has a contraction folding function to avoid interference when the pressure steel pipe 4 tile assembly is reinforced.
After the first hydraulic jack 102 and the positioning baffle plate 103 tightly press and fasten the steel pipe tiles of the pressure steel pipe 4, the inner automatic climbing device 7 and the outer automatic climbing device 8 are controlled to move to the bottom of the assembly joint of the two steel pipe tiles through the climbing gear reducer 803. And controlling the inner automatic climbing device 7 to jack the pressure steel pipe 4 to the position of the inner diameter contour line 107 on the assembly platform 1, and then controlling the outer automatic climbing device 8 to exert pressure on the outer wall of the pressure steel pipe 4, so that spot welding reinforcement is carried out when the joint gap and the butt joint misalignment of two steel pipe tile assemblies meet the relevant requirements. After welding is finished, after the inner automatic climbing device 7 and the outer automatic climbing device 8 are controlled to climb upwards for a certain distance, the assembly and the welding are carried out again until the assembly and the welding of the assembly joint between the two steel pipe tiles are finished completely. The distance of each upward climbing of the inner automatic climbing device 7 and the outer automatic climbing device 8 can be adjusted according to actual conditions. And when the misalignment amount of the assembly joint between the two steel pipe tiles is large, pipe jacking and reinforcing operations are performed at the position.
After the assembly between the two steel pipe tiles is welded to the joint, the platform driving gear 301 is controlled to rotate through the platform driving gear reducer 302, so that the rack guide rail 105 is controlled to rotate, and finally the rotation of the table top 101 is achieved. In the process of rotating the table top 101, when another pair of assembly joints rotates to a position 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 the pair of assembly joints again.
After all the steel pipe tiles are welded to form the penstock 4, the penstock 4 is provided with a stiffening ring 5. 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 a stiffening ring support frame 9 on the outer automatic climbing device 8 is coincident with the lower surface position line of the installation position of the stiffening ring 5, the outer automatic climbing device 8 is fixed. And meanwhile, adjusting the inner automatic climbing device 7 to the same elevation position. Then, the stiffening ring 5 is hoisted to the stiffening ring supporting 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 tightly attached to the outer wall of the pressure steel pipe 4. And when the gap between the inner surface of the stiffening ring 5 and the outer wall of the pressure steel pipe 4 is not more than 1mm, welding and reinforcing the pressure steel pipe 4 between the stiffening rings 5. After the stiffening ring 5 is installed, the assembly is controlled to rotate the platform 1, and then the stiffening ring 5 at the next position is reinforced by spot welding according to the method until all the stiffening rings 5 are installed.
