Description

Technical Field

[0001] This utility model relates to the field of installation mechanism technology, and in particular to a fixing structure for a bridge deck crane. Background Technology

[0002] During the on-site construction of the bridge, bridge cranes are essential large-scale lifting equipment that can lift bridge sections one by one and place them in designated locations for assembly.

[0003] The main truss, front and rear crossbeams and other components of the crane are assembled into a whole module in an open area under the bridge or on the bridge deck to reduce the amount of high-altitude work. Large truck cranes or tower cranes are used to lift the assembled main structure modules to the bridge deck track or the predetermined position. The position and verticality are adjusted by jacks or wedges, and the pins or bolts between the modules are connected to form a complete crane frame. The installation process has the following shortcomings.

[0004] The anchor points on the bridge deck are fixed by bolts or welded flanges. Adjustment with jacks or wedges relies on manual operation, which cannot precisely adjust for errors. The adjustment process requires repeated operations, increasing installation time and labor costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fixing structure for a bridge deck crane, solving the technical problems of rigid bolt connections or welded flanges fixing to bridge deck anchor points, which rely on manual operation for adjustment with jacks or wedges, cannot precisely adjust errors, and require repeated operations during the adjustment process, increasing installation time and labor costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixing structure for a bridge deck crane includes a platform and a frame, wherein the top of the platform is provided with multiple anchor holes, and further includes;

[0008] Four mounting components are provided, each of which is located at the top of the tabletop. Each mounting component includes an embedded plate, a lower support plate, and an upper support plate. A buffer pad is fixedly installed at the top of each upper support plate, and a slanted push rod is rotatably installed at the bottom of each upper support plate. A U-shaped bracket is rotatably installed at the end of each slanted push rod.

[0009] Preferably, the top end of the lower support plate is connected to the bottom end of the upper support plate, and bolts are rotatably installed on both sides of each U-shaped bracket;

[0010] Each of the pre-embedded plates is fixedly installed with a fixing frame at its top, and each fixing frame has a slot at each of its four sides.

[0011] Preferably, each of the four sides of the lower support plate is slidably fitted with a sliding sleeve, each sliding sleeve is rotatably fitted with a threaded rod, and each threaded rod is fixedly fitted with a knob at its top.

[0012] Each threaded rod has a sleeve rotatably mounted at its end, and each sleeve has a positioning plate fixedly mounted at its end that mates with the fixed frame.

[0013] Each of the upper support plates has a ball at its bottom end and each of the lower support plates has a sleeve at its top end.

[0014] Compared with the prior art, the present invention has the following beneficial effects;

[0015] In this invention, the lower support plate and the upper support plate form a ball sleeve structure, which has the freedom of rotation in any direction. The ball can rotate within the sleeve to compensate for installation deviations. By rotating the knob, the threaded rod is driven to rotate, which in turn drives the sliding sleeve to slide, thereby pushing the inclined push rod to tilt. The inclined push rod is connected to the ball sleeve of the upper support plate, which enables flexible adjustment of the angle of the upper support plate mounting surface. The installation angle of the frame can be precisely adjusted according to the actual working conditions, and the installation error can be adjusted quickly and conveniently.

[0016] In this invention, the ball at the bottom of the upper support plate cooperates with the sleeve at the top of the lower support plate. The ball can be rotated to adjust the horizontal plane at the top of the lower support plate, ensuring the high precision of the frame installation. The rotating threaded rod pushes the positioning plate to insert into the fixed frame for fixation. Furthermore, the sleeve and threaded rod can lock themselves because the thread helix angle is less than the friction angle, preventing the structure from loosening. This ensures that the fixed structure of the bridge deck crane is stable and reliable during operation, guaranteeing construction safety. Attached Figure Description

[0023] This application provides a fixing structure for a bridge deck crane, effectively solving the problems of rigid bolt connections or welded flanges fixed to bridge deck anchor points, which rely on manual operation for adjustment using jacks or wedges. This results in imprecise error adjustment, requires repeated operations during adjustment, and increases installation time and labor costs. The lower support plate and upper support plate form a spherical sleeve structure, which has the freedom of rotation in any direction. The ball can rotate within the sleeve to compensate for installation deviations. Rotating the knob drives the threaded rod to rotate, which in turn drives the sliding sleeve to slide, thereby pushing the inclined push rod to tilt. By connecting the inclined push rod with the spherical sleeve of the upper support plate, the angle of the upper support plate's mounting surface can be flexibly adjusted. The installation angle of the frame can be precisely adjusted according to the actual working conditions, and installation errors can be quickly and conveniently adjusted.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that rigid connections with bolts or welded flanges to bridge deck anchor points, coupled with adjustments using jacks or wedges, rely on manual operation, cannot precisely adjust for errors, and require repeated operations during the adjustment process, increasing installation time and labor costs. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a fixing structure for a bridge deck crane, including a platform 11 and a frame 12. The top of the platform 11 is provided with multiple anchor holes, and a pre-embedded plate 13 is fixed inside the anchor holes.

[0027] Four mounting components are provided, each set at the top of the platform 11. Each mounting component includes an embedded plate 13, a lower support plate 14, and an upper support plate 15. A buffer pad 16 is fixedly installed at the top of each upper support plate 15, and a slanted push rod 17 is rotatably installed at the bottom of each upper support plate 15. A U-shaped bracket 18 is rotatably installed at the end of each slanted push rod 17. The upper support plate 15 is connected to the bottom of the frame 12 by bolts. The buffer pad 16 is installed at the top of the upper support plate 15, which can play a role in buffering and shock absorption. The bottom of the lower support plate 14 is assembled and connected to the embedded plate 13. The frame 12 is supported and fixed by the cooperation of the lower support plate 14 and the upper support plate 15. However, the lower support plate 14 and the upper support plate 15 form a ball sleeve structure. The ball sleeve structure realizes the rotational freedom in any direction through the spherical contact surface. In addition, the ball sleeve structure allows the ball to compensate for installation deviations by rotating within the sleeve, which can quickly and conveniently adjust the installation error.

[0028] The top end of the lower support plate 14 is connected to the bottom end of the upper support plate 15. Each U-shaped bracket 18 has bolts rotatably installed on both sides. After the embedded plate 13 and the lower support plate 14 are assembled and installed, the U-shaped bracket 18 is fixed to the outside of the sliding sleeve 21 by tightening the bolts. By continuing to rotate the knob 22, the threaded rod 23 is driven to rotate, which drives the sliding sleeve 21 to slide on the side end of the lower support plate 14, generating a thrust on the end of the inclined push rod 17, causing the inclined push rod 17 to tilt. The top end of the inclined push rod 17 is also connected to the bottom end of the upper support plate 15 through a ball sleeve. Rotating the inclined push rod 17 generates a thrust on the upper support plate 15, allowing the upper support plate 15 to adjust the angle of the mounting surface.

[0029] Each embedded plate 13 is fixedly installed with a fixing frame 19 at its top. Each fixing frame 19 has a slot on each of its four sides. The rotating threaded rod 23 pushes the positioning plate 25, allowing multiple positioning plates 25 to be inserted into the fixing frame 19 for fixing.

[0030] Each of the four sides of the lower support plate 14 is slidably fitted with a sliding sleeve 21. Each sliding sleeve 21 is rotatably fitted with a threaded rod 23. Each threaded rod 23 is fixedly fitted with a knob 22 at its top. Rotating the knob 22 causes the threaded rod 23 to rotate inside the sliding sleeve 21. The rotating sliding sleeve 21 drives the positioning plate 25 to slide inside the lower support plate 14.

[0031] Each threaded rod 23 has a sleeve 24 rotatably mounted at its end, and each sleeve 24 has a positioning plate 25 fixedly mounted at its end that mates with the fixed frame 19. The thread helix angle of the sleeve 24 and the threaded rod 23 is less than the friction angle. When the threaded rod 23 stops rotating, it cooperates with the sleeve 24 and can lock itself.

[0032] Each upper support plate 15 has a ball at its bottom end and each lower support plate 14 has a sleeve at its top end. The upper support plate 15 moves the ball to rotate at the top end of the lower support plate 14, thereby adjusting the horizontal plane of the top end of the lower support plate 14.

[0033] Working principle:

[0034] The first step is to fix the embedded plate 13 at the top of the platform 11 with multiple anchor holes. This is the basic installation step of the entire anchoring structure and provides a reference for the subsequent component installation. The bottom end of the lower support plate 14 is assembled and connected to the embedded plate 13. The bottom end of the upper support plate 15 is rotatably installed with the inclined top rod 17, and the end is rotatably installed with the U-shaped bracket 18. The upper support plate 15 is connected to the bottom end of the frame 12 by bolts, and the top end is installed with a buffer pad 16 for buffering and shock absorption.

[0035] The second step involves assembling and installing the embedded plate 13 and the lower support plate 14, then tightening the bolts on both sides of the U-shaped bracket 18 to fix it to the outside of the sliding sleeve 21. The lower support plate 14 and the upper support plate 15 form a spherical sleeve structure, utilizing the spherical contact surface to achieve rotational freedom in any direction. The installation deviation can be compensated by the rotation of the ball within the sleeve, allowing for rapid adjustment of installation errors. When the threaded rod 23 rotates, it generates a thrust on the positioning plate 25, causing multiple positioning plates 25 to be inserted into the fixed frame 19 for fixation. A ball is set at the bottom of the upper support plate 15, and a sleeve is set at the top of the lower support plate 14. The upper support plate 15 can adjust the ball to rotate at the top of the lower support plate 14, ultimately adjusting the horizontal plane of the top of the lower support plate 14 to ensure the horizontality and stability of the frame 12 installation. At the same time, since the thread helix angle of the sleeve 24 and the threaded rod 23 is less than the friction angle, when rotation stops, the threaded rod 23 and the sleeve 24 can lock themselves in place, ensuring structural stability.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
