Description

Technical Field

[0001] The utility model belongs to the technical field of slope adjustment of bridge variable height sections, and in particular relates to a slope adjustment device of bridge variable height sections. Background Art

[0002] In the construction of large bridges, the jacking construction of steel beams is involved. During the jacking, the distribution beam on the top of the crawler fits with the bottom of the steel beam, and the friction between the contact surfaces provides the jacking force for the movement of the steel beam. Since the longitudinal section line of the bottom of the variable height steel beam is a parabola, there is always a changing slope between the bottom surface of the steel beam and the horizontal plane during the jacking process.

[0003] The prior art patent document with publication number CN 216786882 U provides a slope adjustment device for jacking of steel beams with variable cross-sections of bridges. The device can adapt to slope changes by using a ball crown device and a wedge block with a customized slope, so that the jacking holding point is always in close contact with the bottom of the steel beam, ensuring the stability of the friction force of the contact surface and providing a stable jacking force. Although the current slope adjustment device can adapt to slope changes by using a ball crown device and a wedge block with a customized slope, its slope adjustment direction for jacking of steel beams with variable cross-sections of bridges is relatively single and its practicality is poor. Utility Model Content

[0006] Preferably, the telescopic mechanism includes: the top four corners of the bottom plate and the middle plate are fixedly connected with internal threaded sleeves, and the inside of the internal threaded sleeves are threadedly connected with telescopic rods; the outer surfaces of the internal threaded sleeves are fixedly connected with six structural plates, and the bottoms of the structural plates are respectively fixedly connected to the bottom plate and the middle plate.

[0007] Preferably, the telescopic rod comprises a top block, a threaded block and a hexagonal block; five threaded blocks are provided at the bottom of the top block, two threaded blocks are fixedly connected by a hexagonal block, and the threaded block is threadedly connected to the internal threaded sleeve.

[0008] Preferably, the top plate and the middle plate are both provided with matching alloy blocks near the top block, and the alloy blocks are fixedly connected to the top plate and the middle plate respectively.

[0009] Preferably, angle scales are engraved on opposite sides of the two second fixing blocks, and indicators are fixedly connected to the first fixing blocks near the angle scales.

[0010] Preferably, four sides of the bottom plate and the top plate are fixedly connected with mounting blocks, and mounting holes are provided inside the mounting blocks.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a slope adjustment device for a bridge with a variable height section, such as Figure 1-4 As shown, it includes: a bottom plate 1, a middle plate 2 is arranged on the top of the bottom plate 1, and a top plate 3 is arranged on the top of the middle plate 2; two first fixed blocks 4 are fixedly connected to the top of the bottom plate 1 and the middle plate 2, and the interior of the first fixed blocks 4 is fixedly connected to the rotating shaft 5, and the outer surface of the rotating shaft 5 is rotatably connected to the second fixed block 6, and the second fixed block 6 is fixedly connected to the middle plate 2 and the top plate 3 respectively; the four corners of the top of the bottom plate 1 and the middle plate 2 are provided with a telescopic mechanism 7 for adjusting the slope of the bridge deck.

[0021] It should be noted that the user can use the telescopic mechanism 7 to achieve lateral angle adjustment of the middle plate 2 and longitudinal angle adjustment of the top plate 3. When the middle plate 2 and the top plate 3 are adjusted in a small angle, they drive the second fixed block 6, and the second fixed block 6 rotates slightly with the internal rotation axis 5 of the first fixed block 4 as the center, thereby achieving the function of adjusting the angle in the lateral and longitudinal directions of the bridge's variable-height section. This solves the problem that although the current slope adjustment device can adapt to slope changes by using a spherical crown device and a wedge block with a customized slope, its slope adjustment direction for the top push of the bridge's variable-height section steel beam is relatively single and has poor practicality.

[0022] In a further preferred embodiment of the present invention, Figure 2 As shown, the telescopic mechanism 7 includes: the four top corners of the bottom plate 1 and the middle plate 2 are fixedly connected with internal threaded sleeves 8, and the inside of the internal threaded sleeves 8 are threadedly connected with telescopic rods 9; the outer surfaces of the internal threaded sleeves 8 are fixedly connected with six structural plates 10, and the bottoms of the structural plates 10 are fixedly connected to the bottom plate 1 and the middle plate 2 respectively.

[0023] In this embodiment, the user can use a movable wrench to twist the telescopic rod 9, and the telescopic rod 9 will rise and fall inside the internal threaded sleeve 8 while rotating. The user can rotate the telescopic rod 9 forward or reversely according to his or her needs, thereby achieving the purpose of adjusting the angles of the center plate 2 and the top plate 3.

[0024] In a further preferred embodiment of the present invention, Figure 4 As shown, the telescopic rod 9 includes a top block 11, a threaded block 12 and a hexagonal block 13; five threaded blocks 12 are provided at the bottom of the top block 11, and two threaded blocks 12 are fixedly connected by the hexagonal block 13, and the threaded block 12 is threadedly connected to the internal threaded sleeve 8.

[0025] In this embodiment, the user can use a movable wrench to rotate the hexagonal block 13, which drives the threaded block 12 to rotate. While the threaded block 12 rotates, it cooperates with the internal threaded sleeve 8 to perform a lifting movement, thereby extending and retracting the telescopic rod 9.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the top plate 3 and the middle plate 2 are both provided with matching alloy blocks 14 near the top block 11 , and the alloy blocks 14 are fixedly connected to the top plate 3 and the middle plate 2 , respectively.

[0027] In this embodiment, the occurrence of severe wear of the top plate 3 and the middle plate 2 near the top block 11 can be effectively avoided, thereby increasing the service life and replacement cycle of the device.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, angle scales 15 are engraved on opposite sides of the two second fixing blocks 6 , and indicators 16 are fixedly connected to the first fixing blocks 4 near the angle scales 15 .

[0029] In this embodiment, the user can observe the adjusted angle through the cooperation of the indicator 16 and the angle scale 15, thereby improving practicality.

[0030] In a further preferred embodiment of the present invention, Figure 1 , 3 As shown, four sides of the bottom plate 1 and the top plate 3 are fixedly connected with mounting blocks 17 , and mounting holes 18 are formed inside the mounting blocks 17 .

[0031] In this embodiment, the user can install the device by means of bolts through the mounting holes 18 inside the mounting block 17, thereby improving the stability of the device installation.
