Description

Technical Field

[0001] This invention belongs to the field of building steel structure installation technology, and particularly relates to an auxiliary installation device and its operation method for fishpond flying beam steel structures. Background Technology

[0002] Steel structures, with their advantages of high strength, good seismic resistance, high construction efficiency, and recyclability, are widely used in building construction, bridge engineering, industrial plants, and warehousing facilities. During the construction of steel structures, the assembly accuracy of components directly determines the load-bearing capacity, stability, and service life of the overall structure. In particular, critical parts such as beam-column joints, splice joints, and irregularly shaped components require extremely high positioning accuracy.

[0003] As a type of steel structure, the Fishpond Flying Beam steel structure is a modern cross-shaped spatial cantilever steel structure developed from the traditional ancient Fishpond Flying Beam design. It is widely used in landscape bridges and cultural buildings. Its complex shape, dense intersection of nodes, and varied cantilever angles place high demands on the structure's fabrication, installation accuracy, and construction stability. It has also promoted the advancement of antique steel structure design, spatial truss installation, and high-precision positioning technology.

[0004] During the installation of existing fishpond flying beam steel structures, the steel beams are mostly manually positioned by workers using tools such as measuring tapes, squares, and plumb bobs, or temporary support and limiting are provided by simple brackets. However, this manual positioning and installation method is easily affected by operating experience and fatigue, resulting in problems such as dimensional deviations and angle offsets. This leads to misalignment of the assembled steel structure, requiring rework and increasing construction costs and time. Summary of the Invention

[0015] The operation method of the auxiliary installation device for the fishpond flying beam steel structure includes the following steps: S1: The staff first moves the second base to the lower part of the assembled steel structure main body, starts the second hydraulic cylinder, so that the second lifting seat slides upward until the rollers II contact the bottom of the steel structure main body. During this process, start the second motor, so that the slider II drives the two second clamping plates to slide relatively, realizing that the second clamping plates clamp the steel structure main body from the outside while the rollers II complete the support of the steel structure main body from below; S2: According to the size of the steel beam, the staff slides the limiting sleeve down into the corresponding limiting hole to complete the limiting of the mounting plate. After that, the staff places the steel beam to be installed on the roller one inside the rectangular frame one, turns on the motor one, and makes the slider one drive the clamping plate one to slide relative to each other to complete the clamping and fixing of the steel beam. S3: Move base one to one side of base two until positioning rod one slides into the flared opening of positioning hole one. During this process, the hemispherical end of positioning rod one fits against the flared inner wall of positioning hole one, automatically adjusting the overall position of the floating seat. After positioning rod two slides into positioning hole two, the steel beam and the main steel structure are quickly and accurately connected.

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 , 2As shown in Figures 9 and 10, an auxiliary installation device for a fishpond flying beam steel structure includes a guide rail 1. A base 1 2 and a base 2 3 are slidably connected to the guide rail 1. A hydraulic cylinder 1 4 is fixedly installed on the top of the base 1 2. A lifting seat 1 5 is fixedly connected to the output end of the hydraulic cylinder 1 4. A floating seat 9 is provided on the top of the lifting seat 1 5. A pair of mounting plates 21 are symmetrically arranged on both sides of the floating seat 9. A clamping assembly 1 is provided on the mounting plate 21. A hydraulic cylinder 2 40 is fixedly installed on the top of the base 2 3. A lifting seat 2 41 is fixedly connected to the output end of the hydraulic cylinder 2 40. A pair of brackets 44 are symmetrically fixed to the lifting seat 2 41. A clamping assembly 2 is provided between the brackets 44. A positioning block 1 53 is fixedly connected to the center of the top of the lifting seat 2 41. A pair of positioning blocks 54 are symmetrically arranged on both sides. The bottom of the positioning blocks 54 is fixedly connected to the top of the lifting seat 41. The positioning block 53 is provided with a positioning hole 55. The positioning block 54 is provided with a positioning hole 56. The floating seat 9 is fixedly connected to the mounting bracket 13 on the side near the base 3. The mounting bracket 13 is fixedly connected to the center of the side near the base 3. The positioning rod 14 is symmetrically arranged on both sides of the positioning rod 14. The positioning rod 15 is fixedly connected to the mounting bracket 13. The positioning rod 15 is matched with the positioning hole 56. The side of the positioning hole 55 near the base 2 is trumpet-shaped. The end of the positioning rod 14 near the base 3 is hemispherical. The positioning rod 14 is matched with the positioning hole 55.

[0021] This application takes into account that the existing fishpond flying beam steel structure first completes the assembly and welding of steel beams and other components on the ground, and then carries out the subsequent hoisting construction. During the assembly process, the middle unit is generally used as the starting section, and the installation proceeds outwards in sequence. The rectangular grid in the middle of the structure is used as the starting unit for truss assembly, and the rectangular units are assembled symmetrically outwards to ensure that the center of gravity of the truss as a whole is always located in the center of the structure. The steel structure body is clamped and limited by the base 2 3 in conjunction with the hydraulic cylinder 2 40 and the clamping component 2. The steel beam to be assembled is clamped and fixed by the base 2 3 in conjunction with the hydraulic cylinder 1 4 and the clamping component 1. Then, the base 1 2 is slid to make the steel beam to be assembled move quickly to the steel structure body. At this time, the cooperation between the positioning rod 1 14 and the positioning block 1 53, as well as the positioning rod 2 15 and the positioning block 2 54, realizes the rapid docking and precise positioning of the steel beam and the steel structure body, avoiding dimensional deviations and angular offsets during the installation process.

[0022] During operation, the worker first moves base 2 (3) to the bottom of the assembled steel structure, then activates hydraulic cylinder 2 (40) to slide lifting seat 2 (41) upwards until clamping assembly 2 is aligned with the steel structure. At this point, clamping assembly 2 clamps and secures both sides of the steel structure. Subsequently, the worker quickly clamps and secures the installed steel beam using clamping assembly 1 on the two mounting plates 21. After initial securing, hydraulic cylinder 1 (4) is activated to slide lifting seat 1 (5) upwards until it is level with lifting seat 2 (41). Then, the worker moves base 1 (2) to one side of base 2 (3) until positioning rod 1 (14) aligns with positioning hole 1 (55). The flared end of the positioning rod 14 slides into the positioning hole 55. During this process, the hemispherical end of the positioning rod 14 fits against the flared inner wall of the positioning hole 55, automatically adjusting the overall position of the floating seat 9 until the positioning rod 25 slides into the positioning hole 26. This achieves rapid and precise docking between the steel beam and the main steel structure. The positioning block 53 performs coarse positioning, and the positioning rod 25 completes the final precise positioning, greatly reducing the difficulty of installation alignment. The diameter of the positioning rod 25 is smaller than that of the positioning rod 14. When the hydraulic cylinder 4 and the hydraulic cylinder 2 40 are not activated, the positioning rod 14 and the positioning rod 25 correspond to the positioning hole 55 and the positioning hole 2 56.

[0023] like Figure 2-4 As shown in Figures 9-14, the second positioning block 54 has an opening on the side away from the first positioning block 53. A pair of limiting plates 16 are symmetrically fixed on both sides of the second positioning rod 15 on the mounting bracket 13. The limiting plates 16 are adapted to the opening on the second positioning block 54. The top of the end of the limiting plate 16 away from the mounting bracket 13 has a storage groove 57. The side of the opening on the second positioning block 54 near the base 2 has a storage groove 58. Both the first storage groove 57 and the second storage groove 58 have locking units. The length of the first positioning rod 14 is greater than the length of the second positioning rod 15. The top of the lifting seat 5 has a limiting groove 6. Several limiting rods 7 are evenly fixed in the limiting groove 6. Several limiting blocks 10 are evenly fixed at the bottom of the floating seat 9. The limiting blocks 10 are slidably connected to the limiting rods 7. Springs 8 are fixed between the two sides of the limiting blocks 10 and the inner wall of the limiting groove 6. The locking unit includes a pawl 18 and a torsion spring 20. A support shaft 19 is rotatably connected to both the first storage slot 57 and the second storage slot 58. The pawl 18 is fixed to the support shaft 19. Both ends of the support shaft 19 are fitted with torsion springs 20. A ratchet rack 17 is fixed to the bottom of the limiting plate 16. A ratchet rack 29 is fixed to the top of the opening on the second positioning block 54. The ratchet teeth of the first ratchet rack 17 and the second ratchet rack 29 are inclined in opposite directions. The pawl 18 is compatible with both the first ratchet rack 17 and the second ratchet rack 29. During operation, when the hemispherical end of positioning rod 14 aligns with the trumpet-shaped inner wall of positioning hole 55, the floating seat 9 drives the limiting block 10 to slide horizontally on the limiting rod 7. This causes spring 8 on one side of the limiting block 10 to be compressed, while spring 8 on the other side is stretched. Through the elastic potential energy of spring 8, positioning rod 14 and positioning rod 15 slide into positioning hole 55 and positioning hole 56 respectively, and no longer deviate. After positioning rod 15 slides into positioning hole 56, the limiting plate 16 slides into the opening of positioning block 54 until the installation is complete. The installed steel beam is fitted and aligned with the main steel structure. During this process, the pawls 18 on the limiting plate 16 and the second positioning block 54, together with the torsion spring 20, engage and lock the second ratchet rack 59 and the first ratchet rack 17 respectively, achieving initial locking between the steel beam and the main steel structure. This effectively prevents the steel beam from shifting during installation, thus avoiding misalignment. When the installation is complete and the locking needs to be released, the operator only needs to rotate the support shaft 19 to rotate the pawls 18 into the storage slots 57 and 58, thereby unlocking the limiting plate 16 and the second positioning block 54. Because the teeth of ratchet 17 and ratchet 2 59 are tilted in opposite directions, after the limiting plate 16 slides into the opening of the positioning block 2 54, under the limiting action of the two pawls 18 on ratchet 17 and ratchet 2 59 respectively, the limiting plate 16 will not move back and forth after the steel beam is attached to the main steel structure, thus ensuring the stability during the installation process.

[0024] like Figure 5 As shown, the clamp assembly includes a mounting frame 22, a motor 23, and a clamping plate 27. The mounting frame 22 is fixedly connected to the top of the mounting plate 21. A lead screw 24 is rotatably connected inside the mounting frame 22. A pair of guide rods 25 are fixedly connected inside the mounting frame 22. The pair of guide rods 25 are symmetrically distributed about the lead screw 24. The motor 23 is fixedly installed on the outer wall of the mounting frame 22. One end of the lead screw 24 extends to the outside of the mounting frame 22 and is fixedly connected to the output end of the motor 23. The lead screw 24 is symmetrically provided with double threads with opposite directions of rotation. Two sliders 26 are respectively connected to the lead screw 24 through two lead screw nut pairs. Both sliders 26 are slidably connected to the guide rods 25. The top of each slider 26 is fixedly connected to a clamping plate 27. A pair of rectangular frames 28 are symmetrically fixed to both sides of the mounting frame 22. The bottom of the rectangular frames 28 is fixed to the top of the mounting plate 21. Several rollers 29 are rotatably connected inside the rectangular frames 28. During operation, the worker places the steel beam to be installed on roller 29. At this time, the steel beam is not in contact with the surface of the mounting frame 22. The motor 23 is turned on, which drives the lead screw 24 to rotate, causing the two sliders 26 on the lead screw 24 to slide relative to each other, and the two clamping plates 27 to slide relative to each other, thus clamping and fixing one side of the steel beam to prevent displacement during subsequent installation. This also prevents the steel beam from sliding on roller 29 and causing misalignment during the process of moving the base 2 to connect the steel beam to the main steel structure. After the steel beam and the main steel structure are installed, the motor 23 drives the lead screw 24 to reverse, causing the clamping plates 27 to move away from the side wall of the steel beam and release the clamping state. Then, by sliding the base 2, the roller 29 rolls along the bottom of the installed steel beam and slides to the next steel beam to be installed, facilitating subsequent installation work.

[0025] like Figure 9 As shown, the clamp assembly 2 includes a lead screw 2 45, a motor 2 52, and a clamping plate 2 51. A lead screw 2 45 is rotatably connected between a pair of brackets 44. Guide rods 2 46 are provided on both sides of the lead screw 2 45. The two guide rods 2 46 are fixed between the pair of brackets 44. A motor 2 52 is fixedly installed on the outer wall of one of the brackets 44. One end of the lead screw 2 45 extends to the outside of the bracket 44 and is fixedly connected to the output end of the motor 2 52. The lead screw 2 45 is symmetrically provided with double threads with opposite directions of rotation. The lead screw 2 45 is connected to two sliders 2 47 through two lead screw nut pairs. The sliders 2 47 are slidably connected to the guide rods 2 46. A rectangular frame 2 48 is fixedly connected to the top of the sliders 2 47. Several rollers 2 49 are rotatably connected inside the rectangular frame 2 48. A U-shaped connecting plate 50 is fixedly connected to the outer wall of the rectangular frame 2 48. The clamping plate 2 51 is fixedly connected to the end of the U-shaped connecting plate 50 away from the rectangular frame 2 48. During operation, motor 252 is started, which drives lead screw 245 to rotate, causing two sliders 247 to slide relative to each other and two clamping plates 251 to slide relative to each other, thus completing the clamping and fixing of the steel structure body from the outside and realizing the limiting of base 23. This facilitates the determination of the position of positioning block 153 and positioning block 254, and facilitates the subsequent positioning operation of positioning rod 14 and positioning rod 215. Roller 249 provides auxiliary support for the steel structure body and facilitates clamping by clamping plate 251.

[0026] like Figure 2 , 5As shown in Fig. -8, a number of adjusting plates 11 are symmetrically and fixedly connected to both sides of the floating seat 9. A number of limiting holes 12 are evenly formed in the adjusting plates 11. The mounting plate 21 is slidably connected to the adjusting plate 11. A number of support plates 30 are evenly and fixedly connected to the side of the mounting plate 21 away from the floating seat 9. A limiting sleeve 31 is slidably connected to the support plate 30. A ejector rod 33 is slidably connected to the inner cavity of the limiting sleeve 31. A top block 39 is fixedly connected to the bottom end of the ejector rod 33. An annular plate 34 is slidably connected to the top of the inner cavity of the limiting sleeve 31. The annular plate 34 is fixedly connected to the ejector rod 33. A third spring 35 is fixedly connected between the annular plate 34 and the inner top of the limiting sleeve 31. Chutes 38 are formed on both sides of the inner bottom of the limiting sleeve 31. A clamping block 36 is slidably connected in the chute 38. A fourth spring 37 is fixedly connected between the clamping block 36 and the inner wall of the chute 38. The clamping block 36 is adapted to the limiting hole 12. The cross section of the top block 39 is in the shape of "soil", and the top block 39 is adapted to the clamping block 36; A second spring 32 is fixedly connected between the limiting sleeve 31 and the support plate 30; In the natural state, the bottom end of the limiting sleeve 31 does not contact the top of the adjusting plate 11. The top block 39 presses the clamping block 36 to stretch the fourth spring 37. Fillets are provided at the outer edge of the top block 39, and fillets are provided on the side of the clamping block 36 close to the top block 39; During operation, slide the two mounting plates 21 according to the size of the steel beam until the limiting sleeve 31 is aligned with the corresponding limiting hole 12. The staff first preliminarily fixes the limiting sleeve 31, then presses the ejector rod 33 to make the ejector rod 33 drive the top block 39 to slide downward in the limiting sleeve 31, and the third spring 35 is stretched. After the clamping block 36 is released from the extrusion of the top block 39, it contracts towards the inner cavity of the limiting sleeve 31 under the pulling force of the fourth spring 37. Subsequently, the staff keeps pressing the ejector rod 33, and at the same time slides the limiting sleeve 31 downward until its bottom end contacts the bottom of the limiting hole 12, and then releases the ejector rod 33. At this time, the second spring 32 is compressed, and the ejector rod 33 slides upward and resets under the pulling force of the third spring 35, and presses the clamping block 36 again, so that the outer end of the clamping block 36 slides into the limiting hole 12. Since the pulling force of the third spring 35 is greater than the pulling force of the fourth spring 37, the clamping block 36 will not reset automatically after being pushed out of the limiting sleeve 31 by the top block 39, thus clamping the limiting sleeve 31 in the corresponding limiting hole 12 to complete the limiting and realize the locking of the support plate 30 and the mounting plate 21, which is convenient for the staff to adjust the distance between the two mounting plates 21 according to actual needs; When it is necessary to release the locking of the mounting plate 21, the staff first slides the ejector rod 33 upward so that the top block 39 no longer presses the clamping block 36. The clamping block 36 contracts inward under the pulling force of the fourth spring 37 and disengages from the limiting hole 12. The second spring 32 is released, driving the limiting sleeve 31 to slide upward and disengage from the limiting hole 12, completing the unlocking of the mounting plate 21.

[0027] As Figure 2 、 9As shown, several telescopic rods 42 are evenly fixed between base 2 and lifting seat 5, and several telescopic rods 43 are evenly fixed between base 3 and lifting seat 41. During operation, the telescopic rods 42 and 43 facilitate the sliding of the lifting seats 5 and 41 up and down by the hydraulic cylinders 4 and 40, thus providing auxiliary guidance.

[0028] The operation method of the auxiliary installation device for the above-mentioned fishpond flying beam steel structure is as follows: Figure 15 As shown, it includes the following steps: S1: The staff first moves the base 2 3 to the bottom of the assembled steel structure, starts the hydraulic cylinder 2 40, and makes the lifting seat 2 41 slide up until the roller 2 49 contacts the bottom of the steel structure. During this process, the motor 2 52 is started, and the slider 2 47 drives the two clamping plates 2 51 to slide relative to each other, so that the clamping plates 2 51 clamp the steel structure from the outside while the roller 2 49 supports the steel structure from below. S2: According to the size of the steel beam, the staff slides the limiting sleeve 31 down into the corresponding limiting hole 12 to limit the mounting plate 21. After that, the staff places the steel beam to be installed on the roller 29 in the rectangular frame 28, turns on the motor 23, and makes the slider 26 drive the clamping plate 27 to slide relative to each other to complete the clamping and fixing of the steel beam. S3: Move base 12 towards base 23 until positioning rod 14 slides into the flared opening of positioning hole 155. During this process, the hemispherical end of positioning rod 14 fits against the flared inner wall of positioning hole 155, automatically adjusting the overall position of floating seat 9 until positioning rod 25 slides into positioning hole 256, achieving rapid and precise docking between the steel beam and the main steel structure. At the same time, the pawl 18 on the limiting plate 16 and positioning block 254, together with the torsion spring 20, respectively lock and clamp the ratchet rack 259 and ratchet rack 17, achieving initial locking between the steel beam and the main steel structure, facilitating the stability of subsequent installation.
