Description

Technical Field

[0001] The invention relates to the field of supporting devices, and in particular to a supporting device for highway bridge construction. Background Art

[0002] Support devices for highway bridge construction refer to temporary or permanent equipment used to support and stabilize bridge structures and their construction components during highway bridge construction. The main purpose of these devices is to ensure the stability and safety of the bridge structure during construction so that various construction operations can be carried out smoothly.

[0003] The existing support device for highway bridge construction usually includes a support body, and the support body is usually set to a lifting type. The lifting structure is driven by a cylinder. However, in the existing driving process, the air inside the cylinder is elastic, so the driving support of the cylinder lacks a certain stability. In occasions such as bridge support that require high stability and precise control, the unreliability of braking may bring safety hazards. Another method is to use a threaded rod for lifting movement. The threaded rod can lift and lower the support plate set above the support body. The full thread design of the threaded rod enables it to withstand a more uniform stress distribution, thereby showing higher stability during the support process. However, in the existing threaded rod support process, a motor is usually used to drive the threaded rod to rotate. In the process of continuous rotation of the motor, after the threaded rod rotates to a certain extent, if the motor continues to rotate, the support plate will move out of the thread range of the threaded rod, and the bottom of the support plate will collide with the bottom of the threaded rod, causing serious wear of the equipment and affecting the stability of the operation of the overall support equipment.

[0016] Compared with the related art, the support device for highway bridge construction provided by the present invention has the following beneficial effects:

[0017] 1. During the positive rotation of the first threaded rod, the limit ball set on the positioning bar will move upward inside the threaded groove until the limit ball moves to the terminal position of the threaded groove, and the limit ball will enter the interior of the rotating groove. At this time, the first threaded rod will continue to rotate, and since the bottom end of the fixed cylinder is separated from the first threaded rod, the rotation of the first threaded rod will not drive the fixed cylinder to move upward, and the limit ball will continue to rotate inside the rotating groove, ensuring that even if the fixed cylinder moves out of the threaded groove, the stability of the equipment operation can be guaranteed, and the wear of the equipment is reduced.

[0018] 2. By setting the radial dimension of the thread groove to decrease along its spiral trajectory toward the center of the threaded rod, the thread groove has better fastening force, and a better bite force is formed between the first threaded rod and the fixed cylinder, increasing the contact area and friction. This can further resist external loads and vibrations, reduce the possibility of the fixed cylinder loosening during use, extend the service life of the fixed cylinder to a certain extent, and reduce the maintenance and replacement costs caused by loosening or damage of the fixed cylinder.

[0019] 3. By setting a support plate, the support plate is connected to the connecting frame, so that in the process of the first threaded rod pushing the support plate, the support plate will deflect, so that it can adapt to bridge surfaces with different inclination angles, and in the process of the support plate deflection, the two stabilizing components can further provide supporting force for the support plate to ensure the stability of the overall equipment. By setting the first threaded rod to drive the connecting frame to lift and lower, and the first threaded rod can drive the upper connecting component to synchronously drive the two scraping components to reciprocate, so that when in use, before the support plate fits the gap position at the bottom of the bridge, repair paint can be added to the inside of the support plate. In the process of the operation of the driving component, it not only drives the support plate to support the bridge, but also synchronously drives the scraping component to move, so as to repair the gaps that may appear at the bottom of the bridge, thereby extending the service life of the bridge to a certain extent and reducing the construction waste and resource waste caused by frequent replacement of bridges.

[0020] 4. The reciprocating scraping and coating assembly can also be used to scrape off impurities attached to the bottom of the bridge, so that the location of possible faults such as gaps at the bottom of the bridge can be observed more quickly, allowing staff to respond quickly and carry out temporary reinforcement or repair work.

[0040] In the specific implementation process, Figure 1-Figure 14 As shown, a support device for highway bridge construction is characterized in that it includes a support frame 10, a connecting frame 9 and a supporting plate 1 are provided on the support frame 10, the connecting frame 9 and the supporting plate 1 are movably connected, two scraping and coating assemblies are arranged inside the supporting plate 1, a driving assembly is arranged inside the support frame 10, the driving assembly is used to drive the connecting frame 9 to move up and down, and the driving assembly synchronously drives the two scraping and coating assemblies to reciprocate, and a stabilizing assembly is also arranged on the opposite side of the supporting plate 1;

[0041] The support plate is provided with a sealing sleeve at the upper edge to ensure the sealing of the whole equipment after being attached to the bridge.

[0042] The driving assembly includes a motor 16, a first threaded rod 20 and a connecting assembly. The motor 16 is arranged inside the support frame 10. The output end of the motor 16 is fixedly connected to the bottom end of the first threaded rod 20. The outer wall of the first threaded rod 20 is threadedly connected with a fixing cylinder 18. The upper end of the fixing cylinder 18 is fixedly connected to the bottom of the connecting frame 9. The outer wall of the first threaded rod 20 is provided with a thread groove 25. The upper end of the first threaded rod 20 is connected to the two scraping assemblies through the connecting assembly.

[0043] It should be noted that the motor 16 can drive the first threaded rod 20 to rotate in the forward direction. During the rotation of the first threaded rod 20, the first threaded rod 20 will cause the fixing tube 18 to move upward. The upward movement of the fixing tube 18 will drive the upper connecting frame 9 to move upward. When the connecting frame 9 moves upward, it will eventually drive the supporting plate 1 to move upward, so that the supporting plate 1 fits the bottom of the bridge.

[0044] During the rotation of the first threaded rod 20, the rotation of the first threaded rod 20 also drives the connecting assembly to rotate, and the two scraping assemblies can be synchronously driven by the connecting assembly. When the support plate 1 is attached to the bottom of the bridge, the scraping assemblies can move, so that the paint can be filled in the crack position at the bottom of the bridge;

[0045] The connecting assembly includes a first connecting rod 17, a second connecting rod 23 and a universal joint 21, one end of the first connecting rod 17 extends into the first threaded rod 20, and the outer side wall of the first connecting rod 17 close to the first threaded rod 20 is fixedly connected with a plurality of limit blocks 28, and the plurality of limit blocks 28 are respectively movably arranged in a plurality of limit grooves 27 arranged inside the first threaded rod 20, the upper end of the first connecting rod 17 passes through the connecting frame 9, the end of the first connecting rod 17 close to the connecting frame 9 is fixedly connected to the bottom end of the universal joint 21, the end of the universal joint 21 away from the first connecting rod 17 is fixedly connected to the bottom end of the second connecting rod 23, the second connecting rod 23 extends to the inside of the support plate 1 relative to one end of the universal joint 21, the end of the second connecting rod 23 close to the support plate 1 is fixedly connected with the first bevel gear 12, the opposite side of the universal joint 21 is fixedly connected with a support rod 22, and the opposite ends of the two support rods 22 are respectively fixedly connected to the opposite inner side walls of the connecting frame 9;

[0046] The arrangement of the support rod 22 enables the connection frame 9 to perform deflection movement, and the support rod 22 plays a connecting and supporting effect on the connection frame 9. The deflection movement of the connection frame 9 drives the support plate 1 to perform deflection movement, so that the support plate 1 can adapt to bridge surfaces of different shapes;

[0047] It should be noted that the specific movement mode of the connection assembly here is: during the rotation of the first threaded rod 20, since a plurality of limit blocks 28 are provided on the outside of the first connection rod 17, and the plurality of limit blocks 28 are respectively movably provided in a plurality of limit grooves 27 provided inside the first threaded rod 20, the first connection rod 17 will rise with the rise of the fixed cylinder 18 during the rise of the fixed cylinder 18. Due to the provision of the plurality of limit blocks 28, the first connection rod 17 can be driven to rotate during the rotation of the first threaded rod 20, and the rotation of the first connection rod 17 will eventually drive the second connection rod 23 to rotate through the transmission of the universal joint 21, and the first bevel gear 12 will be driven to move through the second connection rod 23, and the first bevel gear 12 will synchronously drive the two scraping assemblies;

[0048] By setting a plurality of limit blocks 28, the overall drive transmission will not be affected during the rising process of the fixed cylinder 18, so that the overall structure is stable. The stable structure can more effectively resist the influence of external loads and internal stresses, thereby improving the strength and durability of the overall structure.

[0049] A partition 7 is fixedly connected to the middle position of the interior of the support frame 10, and the partition 7 separates the support frame 10 into two discharge chambers, wherein a sealing coating is provided on the upper end of the partition 7, and two scraping and coating assemblies are respectively arranged inside the two discharge chambers, and the scraping and coating assemblies include a second bevel gear 13, a second threaded rod 11, a coating plate 8 and a guide plate 24, the first bevel gear 12 is meshed with the second bevel gear 13, one side of the second bevel gear 13 is fixedly connected to one end of the second threaded rod 11, the end of the second threaded rod 11 relative to the second bevel gear 13 passes through the partition 7, and the end of the second threaded rod 11 close to the outside of the partition 7 passes through the coating plate 8, the cross section of the coating plate 8 is set to a triangle, and a through-flow groove 29 is provided at the bottom of the coating plate 8, and the guide plate 24 is arranged in the through-flow groove 29, and the initial state of the guide plate 24 is inclined, and the guide plate is connected to the inner upper side of the through-flow groove 29 through the mounting rod 31;

[0050] Wherein, the second threaded rod 11 mentioned above is a bidirectional threaded rod;

[0051] The specific operation process of the scraper assembly is as follows: in the above, when the first bevel gear 12 rotates, the two second bevel gears 13 can be driven to rotate synchronously. During the rotation of the two second bevel gears 13, the two second threaded rods 11 can be driven to rotate at the same time. The reciprocating motion of the coating plate 8 is achieved through the rotation of the two second threaded rods 11.

[0052] In specific use, during the rising process of the support plate 1, the repair paint can be added to the inside of the two discharge chambers on the support plate 1. Since the cross section of the coating plate 8 is set to be triangular, during the reciprocating motion of the coating plate 8, the repair paint can be guided upward by the relatively inclined side walls of the coating plate 8. Through the contact and fit between the coating plate 8 and the bottom of the bridge, the repair paint is applied to the gap after it contacts the gap, thereby completing the gap repair.

[0053] During the reciprocating motion of the coating plate 8, the repair paint can be pushed to flow in the frame, thereby achieving the stirring of the paint. Moreover, since the through-flow groove 29 is provided at the bottom of the coating plate 8, during the movement of the coating plate 8, the repair paint can continuously flow on the opposite side of the coating plate 8 through the through-flow groove 29, thereby improving the overall fluidity of the paint and reducing the stratification and precipitation of the paint.

[0054] In addition, during the reciprocating motion of the coating plate 8, the repair paint will also push the guide plate to rotate during its flow. The rotation of the guide plate will further promote the mixing and stirring of the materials, making the coating more uniform inside the frame, reducing the additional load and stress on the second threaded rod 11 due to uneven stirring, and reducing the damage to the second threaded rod 11. The setting of the guide plate disperses the direct impact force of part of the coating on the coating plate 8. After reducing the impact force on the coating plate 8, the coating plate 8 runs more smoothly, which reduces the load on the second threaded rod 11 to a certain extent, reduces its wear risk, and increases the service life of the second threaded rod 11.

[0055] Two feed pipes 19 are fixedly connected to one side of the support plate 1. The two feed pipes 19 are threadedly connected to a cover body 30 on one side away from the support plate 1. The two feed pipes 19 are movably arranged in an arc-shaped through groove arranged on one side of the connection frame 9 and slide along the arc-shaped through groove. Two discharge pipes 37 are also arranged on one side of the support plate.

[0056] It should be noted that when the two feed pipes 19 are in use, when the support plate 1 is deflected, the two feed pipes 19 can slide inside the arc-shaped through groove, and the cover body 30 can be opened so that after the support plate 1 is attached to the bottom of the bridge, repair paint can be added to the inside of the support plate 1, thereby ensuring the stability and practicality of the overall equipment operation;

[0057] By setting two discharge pipes 37, during the specific use process, the two discharge pipes 37 will be sealed by a cover, and when the device is in a tilted state, the paint inside the support plate 1 will tilt. After the scraping is completed, the excess paint can be discharged by opening the two discharge pipes 37 and the two feed pipes 19, which is convenient for the subsequent use of the device;

[0058] The stabilizing assembly includes a first movable plate 2 and a second movable plate 3. One end of the first movable plate 2 is connected to the bottom of the support frame 10 through a first rotating rod 14. One end of the first movable plate 2 away from the support frame 10 extends to the inside of the second movable plate 3. A plurality of engaging holes 4 are provided on the second movable plate 3. The first movable plate 2 and the second movable plate 3 are installed by bolts 5. The bottom of the second movable plate 3 is connected to a base 6 provided at the bottom of the support frame 10 through a second rotating rod 15.

[0059] It should be noted that when the support plate 1 is attached to the bottom of the bridge, due to the provision of the first movable plate 2 and the second movable plate 3, during the rising process of the support plate 1, the first movable plate 2 will move upward, and the first movable plate 2 will move inside the second movable plate 3, and when the support plate 1 is completely in the state of attaching to the bottom of the bridge, the engaging holes 4 on the first movable plate 2 can be aligned with the corresponding positions on the second movable plate 3, and the first movable plate 2 and the second movable plate 3 can be finally fixed by the bolts 5, and since the first movable plate 2 and the second movable plate 3 are in an inclined state as a whole during the movement, a triangle is formed between the first movable plate 2 and the second movable plate 3 and the fixing tube 18, thereby improving the stability during the support;

[0060] A positioning bar 36 is provided inside the fixed cylinder 18, and a limiting ball 35 is provided at the end position of the positioning bar 36. The radial dimension of the thread groove 25 is reduced toward the center of the threaded rod along its spiral trajectory, forming a space for the limiting ball 35 to move. A rotating groove 26 is provided at the terminal position of the thread groove 25, and the limiting ball 35 is provided in the rotating groove 26. The rotating groove 26 is connected with the thread groove 25, and a reset component is provided at the position where the rotating groove 26 and the thread groove 25 are connected. The reset component includes a reset plate 32 and a movable block 34. One end of the movable block 34 is fixedly connected to one side of the inner part of the thread groove 25. A torsion spring 33 is provided on the outer side wall of the movable block 34 away from the thread groove 25, and the torsion spring 33 is installed inside the reset plate 32.

[0061] It should be noted that during the positive rotation of the first threaded rod 20, the limiting ball 35 provided on the positioning bar 36 will move upward inside the thread groove 25 until the limiting ball 35 moves to the terminal position of the thread groove 25, and the limiting ball 35 will enter the inside of the rotation groove 26. At this time, the first threaded rod 20 will continue to rotate, and since the bottom end of the fixing cylinder 18 is separated from the first threaded rod 20, the rotation of the first threaded rod 20 will not drive the fixing cylinder 18 to move upward, and the limiting ball 35 will continue to rotate inside the rotation groove 26. When the limiting ball 35 moves, it will first contact the reset plate 32, and the reset plate 32 is pushed by the limiting ball 35. Since the hinged position of the reset plate 32 is at the position of the movable block 34, when the reset plate 32 is deflected, the torsion spring 33 will be compressed until the limiting ball 35 completely passes the position of the reset plate 32. At this time, the reset plate 32 will be reset again due to the action of the torsion spring 33.

[0062] The bottom end of the reset plate 32 is configured to be in an arc shape, which matches the shape of the thread groove 25, and after the reset plate 32 rotates 90°, it will fit to the position where the thread groove 25 and the rotation groove 26 are connected;

[0063] When the first threaded rod 20 is reversed, the limiting ball 35 will contact the other side of the reset plate 32. At this time, due to the action of the torsion spring 33 and the reset plate 32, a guiding effect is achieved, and the limiting ball 35 is guided so that the limiting ball 35 can return to the thread groove 25 from the position where the thread groove 25 is connected to the rotation groove 26. In the process of the continuous reversal of the first threaded rod 20, the upper fixing cylinder 18 will be driven to descend and reset again, and the overall device will not produce motion interference.

[0064] Furthermore, by setting the radial dimension of the thread groove 25 to decrease along its spiral trajectory toward the center of the threaded rod, the thread groove 25 has better fastening force, and a better bite force is formed between the first threaded rod 20 and the fixing tube 18, thereby increasing the contact area and friction force, thereby further resisting external loads and vibrations, reducing the possibility of the fixing tube 18 loosening during use, and extending the service life of the fixing tube 18 to a certain extent, reducing the maintenance and replacement costs caused by loosening or damage of the fixing tube 18.

[0065] The working principle provided by the present invention is as follows: during the use of the device, the motor 16 can drive the first threaded rod 20 to rotate in a positive direction. During the rotation of the first threaded rod 20, the first threaded rod 20 will cause the fixing tube 18 to move upward, and the upward movement of the fixing tube 18 will drive the upper connecting frame 9 to move upward. When the connecting frame 9 moves upward, it will eventually drive the supporting plate 1 to move upward, so that the supporting plate 1 fits the bottom of the bridge;

[0066] During the rotation of the first threaded rod 20, since a plurality of limit blocks 28 are provided on the outside of the first connecting rod 17, and the plurality of limit blocks 28 are respectively movably provided in a plurality of limit grooves 27 provided inside the first threaded rod 20, during the rising process of the fixed cylinder 18, the first connecting rod 17 will rise along with the rising of the fixed cylinder 18. Due to the provision of the plurality of limit blocks 28, during the rotation of the first threaded rod 20, the first connecting rod 17 can be driven to rotate, and the rotation of the first connecting rod 17 will eventually drive the second connecting rod 23 to rotate through the transmission of the universal joint 21, and the first bevel gear 12 is driven to move through the second connecting rod 23, and the first bevel gear 12 will synchronously drive the two second bevel gears 13 to rotate synchronously. During the rotation of the two second bevel gears 13, the two second threaded rods 11 can be driven to rotate at the same time, and the reciprocating motion of the coating plate 8 is realized through the rotation of the two second threaded rods 11.

[0067] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0068] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
