Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge support adjustment device. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, a bridge is also extended to refer to a building that is built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient. During the construction of a bridge, a supporting structure is required to provide auxiliary support.

[0003] A Chinese patent with application number 202321606828.2 discloses a bridge support adjustment device, which relates to the field of bridge support technology to solve the problem that workers are required to continuously rotate threaded rods, which makes it inconvenient for workers to quickly adjust the support position. The device includes a bridge support assembly; the stabilizing assembly is provided with four groups, and the four groups of stabilizing assemblies are installed on the outside of the bridge support assembly; in the bridge support adjustment device, when the staff turns the handle, the threaded ring rotates, and the position of the bridge support block changes, which is convenient for the staff to adjust the support height, and convenient for the staff to quickly adjust the support position of the bridge support block, reducing the labor intensity of the staff.

[0004] The above scheme connects the two hollow tubes through the positioning pin, and then uses the rotating ring to limit the positioning pin. However, in actual use, when the upper hollow tube B is subjected to force, the overall weight of the hollow tube B will be applied to the positioning pin, and when the rotating ring is rotated to adjust the positioning pin, the rotating ring squeezes the lower side of the positioning pin, which can easily cause the positioning pin to be damaged by excessive force, resulting in safety hazards in the use of the equipment, and when the height of the support plate is accurately adjusted, the labor-saving rod needs to be frequently disassembled and assembled to drive the rotating ring. When the adjustment height is high, the operation is inconvenient, resulting in reduced equipment installation efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5As shown, a bridge support adjustment device comprises a base 1 and a support shell 4, a driving box 2 is mounted on the upper side of the base 1, an adjustment assembly 3 is arranged inside the driving box 2, the adjustment assembly 3 is matched and connected with the bottom end of the support shell 4, a support column 5 is slidably matched inside the support shell 4, the support column 5 can slide up and down relative to the support shell 4, and a plurality of inclined grooves 6 are provided on both sides of the support column 5;

[0026] Both sides of the inner wall of the support shell 4 are provided with a clamping mechanism 7, and each set of the clamping mechanism 7 includes a plurality of clamping blocks 71 connected to the corresponding side walls of the support shell 4, a slide groove 72 provided on the corresponding side walls of the support shell 4, a driving rod 73 that slides and elastically fits on the corresponding inner wall of the slide groove 72, a plurality of connecting rods 74 fixedly connected to one side of the driving rod 73, a baffle 75 fixedly connected to the connecting rod 74, a handle 76 fixedly connected to the other side of the driving rod 73, a plurality of limiting grooves 77 provided on one side of the inner wall of the slide groove 72, and a plurality of stop grooves 78 provided in the slide groove 72. The strip groove 78 on the other side of the wall and the block 71 are both inclined upwardly arranged, one end of the block 71 is rotatably connected to the inner wall of the support shell 4 by a hinge, and a first spring is connected between the other end and the support shell 4, and is elastically connected through the first spring. A second spring is connected between the upper end of the drive rod 73 and the slide groove 72, and is elastically connected through the second spring. The connecting rod 74 slides in the corresponding limit groove 77, the handle 76 slides in the strip groove 78, the baffle 75 cooperates with the corresponding block 71, and the block 71 cooperates with the corresponding inclined groove 6.

[0027] When in use, the support column 5 is lifted with the assistance of lifting equipment and other tools, and the support column 5 moves upward in the support shell 4, squeezing the block 71 to rotate toward the inner wall of the support shell 4. When the support column 5 is pulled to a suitable height, the height of the inclined groove 6 is higher than the corresponding height of the block 71, and the corresponding multiple blocks 71 are connected to the inclined grooves 6 on both sides of the support column 5 under the action of the spring. The support column 5 is released and moves downward under the action of gravity, so that the block 71 supports the inclined groove 6, and the position of the support column 5 in the support shell 4 is fixed.

[0028] In some specific embodiments, such as Figure 5 As shown, in order to facilitate the support column 5 to effectively contact and support the bridge, a support plate 8 is fixedly connected to the upper end of the support column 5, and reinforcement blocks 9 are fixedly connected to both sides of the support column 5, and the reinforcement blocks 9 are fixedly connected to the support plate 8.

[0029] In some specific embodiments, such as Figure 2As shown, in order to facilitate the precision adjustment of the support shell 4, the adjustment component 3 includes a threaded sleeve 31 slidably fitted on the upper side of the drive box 2, a threaded rod 32 rotatably fitted on the upper side of the base 1, a rotating shaft 33 rotatably fitted on one side of the drive box 2 and meshingly connected with the threaded rod 32, and a driving disk 34 fixedly connected to the other end of the rotating shaft 33. A half gear 1 is coaxially arranged at the bottom end of the threaded rod 32, and a half gear 2 adapted to the half gear 1 is coaxially arranged on the rotating shaft 33. Gear 1 is meshingly connected with gear 2. The threaded rod 32 is threadedly fitted in the threaded sleeve 31. The threaded sleeve 31 is fixedly connected to the support shell 4. The rotating shaft 33 is driven to rotate by rotating the driving disk 34. Under the action of the threaded rod 32 meshingly connected therewith, the threaded sleeve 31 is raised to achieve precise adjustment of the height of the support plate 8.

[0030] Then, by rotating the driving disk 34, the rotating shaft 33 is driven to rotate, so that the threaded rod 32 engaged therewith is rotated, and the threaded sleeve 31 drives the support shell 4 to move upward, and the supporting height of the support plate 8 is accurately adjusted to support the bridge, and then the force-bearing rod on the turntable 14 is rotated to make the support leg 13 extend from the support tube 12 and contact the ground, thereby increasing the supporting effect of the support shell 4. When the equipment needs to be dismantled, the support plate 8 is separated from the bridge by reversing the driving disk 34, and the handle 76 is pushed up to make the driving rod 73 drive the connecting rod 74 to move upward, so that the baffle 75 squeezes the block 71, so that the block 71 rotates out of the corresponding inclined groove 6, and the limit on the support column 5 is cancelled, so that the support column 5 can be recovered into the support shell 4.

[0031] In some specific embodiments, such as Figure 2 As shown, in order to facilitate fixing the base 1 , a plurality of mounting holes 10 are vertically opened on the base 1 , and mounting bolts 11 are installed inside the mounting holes 10 for mounting the base 1 and improving the connection effect of the base 1 .

[0032] In some specific embodiments, such as Figure 1 As shown, in order to enhance the stability of the support shell 4, a plurality of support tubes 12 are fixedly connected around the support shell 4, and the inner wall threads of the support tubes 12 are equipped with support legs 13. When supporting the support shell 4, the support legs 13 are rotated to extend the support legs 13 to provide auxiliary support to the support shell 4.

[0033] In some specific embodiments, such as Figure 1 As shown, in order to facilitate driving the supporting leg 13, a turntable 14 is installed on the supporting leg 13, and a plurality of force-bearing rods are fixedly connected to the turntable 14. The setting of the turntable 14 facilitates driving the supporting leg 13 and saves manual labor.

[0034] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0035] When in use, the support column 5 is lifted with the assistance of a lifting device or other tools, the support column 5 moves upward in the support shell 4, and the squeeze block 71 rotates toward the inner wall of the support shell 4. When the support column 5 is pulled to a suitable height, the corresponding multiple blocks 71 are connected with the inclined grooves 6 on both sides of the support column 5 under the action of the spring, and the support column 5 is released. Under the action of gravity, the support column 5 moves downward, so that the blocks 71 support the inclined grooves 6. The position of the support column 5 in the support shell 4 is fixed, and then the rotating shaft 33 is driven to rotate by rotating the driving disk 34, so that the threaded rod 32 engaged therewith rotates, and the threaded sleeve 31 drives the support shell 4 to move upward, and the support height of the support plate 8 is increased. The degree can be precisely adjusted, and there is no need to frequently disassemble the labor-saving rod for driving, which saves manual labor, supports the bridge, and then rotates the force-bearing rod on the turntable 14 to make the support leg 13 extend from the support tube 12 and contact the ground, thereby increasing the support effect on the support shell 4. When the equipment needs to be dismantled, the support plate 8 is separated from the bridge by reversing the drive disk 34, and the handle 76 is pushed up to make the drive rod 73 drive the connecting rod 74 to move upward, so that the baffle 75 squeezes the block 71, so that the block 71 rotates out of the corresponding inclined slot 6, cancels the limit of the support column 5, and allows the support column 5 to be recovered into the support shell 4, which is convenient for next use;

[0036] By setting up the clamping mechanism 7, when adjusting the height of the support column 5, the support column 5 can be pulled up to the required height. With the support of the clamping block 71 on the inclined groove 6, the position of the support column 5 in the support shell 4 is fixed. The force on the support column 5 acts on multiple clamping blocks 71, so the force is evenly applied to the support column 5 and it is not easy to be damaged.

[0037] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
