Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a Bailey bridge scaffolding tool for wind turbine installation. Background Technology

[0002] Bailey bridges are standardized, modular truss structures originally used in military bridge engineering. They have since been widely applied in civil buildings, temporary supports, and heavy equipment installation. In wind turbine installation, Bailey bridges are mainly used as temporary support platforms or transportation / hoisting auxiliary structures to support heavy components such as blades and towers, ensuring their stability during assembly and hoisting.

[0003] In existing systems, when installing wind turbine components, shims are typically welded to designated locations on the Bailey bridge to facilitate their transport to the designated positions. This provides stable support for the components during transport, ensuring their stability during the journey.

[0004] However, since the required transport heights for wind turbine components vary, when transporting components to different heights, it is necessary to first cut the connection between the shim and the Bailey bridge, and then move the shim to the appropriate position and re-weld it. This process is not only time-consuming and labor-intensive, but also causes great damage to the Bailey bridge during the disassembly and installation of the shim, thus affecting the service life of the Bailey bridge. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a Bailey bridge jacking tool for wind turbine installation, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] The Bailey bridge scaffolding elevation fixture for wind turbine installation includes: a Bailey bridge body with pulleys on it, a steel wire rope on the pulleys, and an elevation platform at one end of the steel wire rope; an elevation assembly on the elevation platform, comprising a long rack and a connecting gear, the long rack being mounted on the Bailey bridge body and the connecting gear having a driven gear meshing with it; and a fixing assembly on the elevation platform, comprising a connecting plate on the elevation platform, a short rack on the connecting plate, and a locking component on the connecting plate.

[0008] Furthermore, the elevation assembly also includes three sets of long racks evenly arranged on the Bailey frame body, two sets of drive gears symmetrically arranged on both sides of the elevation platform, the drive gears meshing with the long racks, a jack on one side of the elevation platform, and a bracket at the output end of the jack.

[0009] Furthermore, three sets of slide rails are evenly arranged on the Bailey frame body, and sliding sleeves are installed on the raised platform corresponding to the slide rails, with the sliding sleeves movably mounted on the slide rails.

[0010] Furthermore, the drive gear is located in the middle of the raised platform and is meshed with a long rack.

[0011] Furthermore, the driven gear is rotatably mounted on one side of the raised platform, and a connecting rod is provided on the side of the driven gear away from the raised platform, with a rotating handle provided on one side of the connecting rod.

[0012] Furthermore, the fixing component also includes a trapezoidal groove set on the raised platform, and a trapezoidal block is set on the connecting plate corresponding to the trapezoidal groove, with the trapezoidal block movably set in the trapezoidal groove.

[0013] Furthermore, an elastic element is provided between the trapezoidal block and the trapezoidal groove, and a telescopic rod is provided inside the elastic element, with the telescopic rod positioned between the trapezoidal block and the trapezoidal groove.

[0014] Furthermore, the locking component includes a threaded rod threaded on the connecting plate, which passes through the trapezoidal block and extends into the trapezoidal groove. A threaded hole is provided on the inner side of the trapezoidal groove corresponding to the threaded rod, and the threaded hole matches the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. When adjusting the height of the raised platform, the steel wire rope pulls the raised platform to a certain height. The operator turns the handle, which causes the driven gear to drive the connecting gear to move along the long rack, thereby guiding the movement direction of the raised platform. At the same time, the sliding sleeve moves along the slide rail, which makes it easy for the operator to fine-tune the height of the raised platform so that the installation height of the raised platform is more matched with that of the wind turbine components. This makes it easier for the operator to adjust the position of the raised platform and reduces damage to the Bailey bridge itself.

[0017] 2. When the raised platform is moved to the designated position, the connecting plate is pulled to move the short rack closer to the long rack until the short rack and the long rack mesh with each other. At this time, the threaded rod and the threaded hole are aligned. Then, the operator controls the threaded rod to spiral into the threaded hole, thereby locking the position of the short rack and fixing the position of the raised platform.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 - Figure 5As shown, this utility model provides a Bailey bridge elevation tool for wind turbine installation, including: a Bailey bridge body 1, a pulley 21 on the Bailey bridge body 1, a steel wire rope 22 on the pulley 21, and an elevation platform 2 at one end of the steel wire rope 22; it also includes: an elevation component on the elevation platform 2, the elevation component including a long rack 4 and a connecting gear 15, the long rack 4 being disposed on the Bailey bridge body 1, and a driven gear 16 meshing on the connecting gear 15; and a fixing component on the elevation platform 2, the fixing component including a connecting plate 10 disposed on the elevation platform 2, a short rack 11 disposed on the connecting plate 10, and a locking component disposed on the connecting plate 10.

[0027] In the above scheme:

[0028] 1. Through the cooperation of steel wire rope 22 and pulley 21, the other end of the steel wire rope can be pulled by personnel or connected to the grounded winch. The force on the other end of the steel wire rope can drive the steel wire rope 22 to move quickly a certain distance, thereby adjusting the position of the raised platform 2.

[0029] 2. The cooperation between the sliding sleeve 6 and the slide rail 5 makes it easy for the staff to adjust the position of the raised platform 2. The driven gear 16 drives the connecting gear 15 to move on the long rack 4, so that the staff can make fine adjustments to the position of the raised platform 2.

[0030] 3. After adjusting the position of the raised platform 2, pull the connecting plate 10 to move the short rack 11 closer to the long rack 4 until the long rack 4 and the short rack 11 mesh with each other. Then, control the threaded rod 9 to spiral into the threaded hole 8 to fix the position of the short rack 11, thereby fixing the raised platform 2.

[0031] In this embodiment, the elevation assembly also includes three sets of long racks 4 evenly arranged on the Bailey frame body 1, two sets of drive gears 3 symmetrically arranged on both sides of the elevation platform 2, the drive gears 3 meshing with the long racks 4, a jack 20 is provided on one side of the elevation platform 2, and a bracket 19 is provided at the output end of the jack 20.

[0032] In the above scheme: when the raised platform 2 moves, it can drive the drive gear 3 to rotate, so that the drive gear 3 moves on the long rack 4, thereby achieving the guiding effect on the movement of the raised platform 2.

[0033] In this embodiment, three sets of slide rails 5 are evenly arranged on the Bailey frame body 1, and a sliding sleeve 6 is provided on the raised platform 2 corresponding to the slide rails 5. The sliding sleeve 6 is movably arranged on the slide rails 5.

[0034] In the above scheme, the sliding sleeve 6 slides on the slide rail 5, which facilitates the increase of the mobility of the raised platform 2.

[0035] In this embodiment, the drive gear 3 is located in the middle of the raised platform 2, and the drive gear 3 is meshed with the long rack 4.

[0036] In the above scheme, the cooperation between the drive gear 3 and the long rack 4 can guide the movement direction of the raised platform 2.

[0037] In this embodiment, the driven gear 16 is rotatably disposed on one side of the raised platform 2, and a connecting rod 17 is provided on the side of the driven gear 16 away from the raised platform 2, and a rotating handle 18 is provided on one side of the connecting rod 17.

[0038] In the above scheme: by rotating the handle 18, the staff can drive the connecting gear 15 to rotate through the driven gear 16, which makes it convenient for the staff to make fine adjustments to the position of the raised platform 2.

[0039] In this embodiment, the fixing component also includes a trapezoidal groove 7 disposed on the raised platform 2, and a trapezoidal block 12 disposed on the connecting plate 10 corresponding to the trapezoidal groove 7, the trapezoidal block 12 being movably disposed within the trapezoidal groove 7.

[0040] In the above scheme, the cooperation between the trapezoidal groove 7 and the trapezoidal block 12 can limit the movement direction of the connecting plate 10.

[0041] In this embodiment, an elastic element 14 is provided between the trapezoidal block 12 and the trapezoidal groove 7, and a telescopic rod 13 is provided inside the elastic element 14. The telescopic rod 13 is provided between the trapezoidal block 12 and the trapezoidal groove 7.

[0042] In the above scheme, the elastic force of the elastic element 14 can drive the short rack 11 to disengage from the long rack 4 when the position of the raised platform 2 needs to be adjusted, thereby releasing the restriction on the raised platform 2.

[0043] In this embodiment, the locking component includes a threaded rod 9 threaded on the connecting plate 10, which passes through the trapezoidal block 12 and extends into the trapezoidal groove 7. A threaded hole 8 is provided on the inner side of the trapezoidal groove 7 corresponding to the threaded rod 9, and the threaded hole 8 matches the threaded rod 9.

[0044] In the above scheme, the engagement of the threaded rod 9 and the threaded hole 8 can fix the position of the short rack 11, so that the short rack 11 and the long rack 4 can maintain mutual meshing.

[0045] In this embodiment, since the threaded rod 9 is initially inside the threaded hole 8, when the position of the raised platform 2 needs to be adjusted, the operator twists the threaded rod 9 to disengage it from the threaded hole 8. At this time, the elastic force of the elastic element 14 can drive the short rack 11 to disengage from the set of long racks 4 in the middle of the Bailey frame body 1 through the connecting plate 10, thereby releasing the position restriction on the raised platform 2. Then, the operator can quickly adjust the position of the raised platform 2 through the cooperation of the wire rope 22 and the pulley 21. When the raised platform 2 moves to a certain position, by rotating the rotating handle 18, the connecting rod 17 drives the driven gear 16 to rotate, thereby driving the connecting gear 15 to rotate, so that... As the platform moves along the long rack 4, the three sets of sliding sleeves 6 installed on the side of the raised platform 2 near the Bailey frame body 1 move on the slide rail 5, thereby increasing the sliding ability of the raised platform 2. At the same time, the drive gears 3 on both sides of the raised platform 2 also move on the long rack 4, guiding the movement direction of the raised platform 2. After the position of the raised platform 2 is adjusted, the short rack 11 and the long rack 4 are meshed by pulling the connecting plate 10. At this time, the threaded hole 8 and the threaded rod 9 are aligned. By turning the threaded rod 9 into the threaded hole 8, the raised platform 2 can be fixed, which makes it easier for the staff to adjust the position of the raised platform 2 and also reduces damage to the Bailey frame body 1.
