Description

Technical Field

[0001] This utility model relates to the field of main beam support technology, and in particular to a main beam support device for road and bridge construction. Background Technology

[0002] Roads and bridges, as an important component of transportation infrastructure, play a vital role in regional economic development, social exchange, and the transport of goods.

[0003] The main components of the main beam support device for bridge and road construction include: the main support structure consists of columns and crossbeams; the adjustment components include jacks and adjusting bolts; the connecting components include welded parts, bolted connections, and pins; the stabilizing components include diagonal braces and scissor braces; and the buffer components include rubber pads and spring shock absorbers. All components work together to ensure the safety and stability of the main beam construction.

[0004] In existing technologies, the contact area between some main beam support devices and the ground or foundation structure is relatively small. When bearing a large main beam load, the pressure per unit area will increase, making it easier for local foundation or foundation structure to settle. The lack of extension of the fixing plate makes it difficult for the support device to adapt to irregular terrain. On some undulating terrains, it is difficult to find enough reliable support points, and some supports may even be suspended. This leads to uneven stress on the support device, affecting the stress distribution and structural safety of the main beam. Therefore, a main beam support device for road and bridge construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a main beam support device for road and bridge construction, which aims to improve the problems in the existing technology that the small contact area with the ground or foundation structure makes it easy to cause local settlement when bearing large loads, and the lack of fixed plate extension function makes it difficult to adapt to irregular terrain, affecting the stress distribution and structural safety of the main beam.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bridge and road construction main beam support device includes a support column. A motor is fixedly connected inside the support column. An elliptical block is fixedly connected to the drive end of the motor. A fixed plate is fixedly connected to the bottom of the support column. Multiple rotating rods are rotatably connected inside the fixed plate. Springs are fixedly connected to adjacent sides of each rotating rod. Fixed columns are fixedly connected inside each of the multiple rotating rods. Connecting rods are rotatably connected to opposite sides of each rotating rod. A rotating shaft is fixedly connected to adjacent sides of each connecting rod. A rotating shaft is fixedly connected inside the connecting rod. A connecting plate is fixedly connected to opposite sides of the connecting rod. An adjustment assembly for lifting and lowering is fixedly connected inside the support column.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes a protective shell, the left side of which is fixedly connected to the right side of the support column. A second motor is fixedly connected inside the protective shell, and a worm gear is fixedly connected to the drive end of the second motor. A lead screw is rotatably connected inside the support column, and a worm wheel is fixedly connected to the outside of the lead screw. The outside of the worm wheel and the outside of the worm gear are meshed. A connecting rod is threadedly connected to the outside of the lead screw, and two sliding blocks are fixedly connected to the outside of the connecting rod.

[0010] As a further description of the above technical solution:

[0011] The outer side of the elliptical block is in contact with the adjacent side of the plurality of rotating rods, and the upper and lower sides of the plurality of fixed columns are fixedly connected to the inner wall of the fixed plate.

[0013] The upper and lower sides of the plurality of rotating rods are slidably connected to the inner wall of the fixed plate, and the upper and lower sides of the plurality of connecting rods are slidably connected to the inner wall of the fixed plate.

[0014] As a further description of the above technical solution:

[0015] The adjacent sides of the plurality of springs are fixedly connected to the opposite sides of the fixed plate, and the interior of the fixed plate is slidably connected to the exterior of the two connecting plates;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a motor is installed inside the support column to drive the elliptical block to rotate, causing the rotating rod to rotate around its connection point with the fixed plate. When the rotating rod rotates, it drives the connecting rod to move, and the connecting rod drives the connecting plate to slide inside the fixed plate. At the same time, the spring is stretched or contracted, which enhances the stability of the device. By extending the support of the fixed plate, the contact area between the support device and the ground or foundation structure can be expanded, ensuring that the support device can effectively support the main beam under different terrain conditions.

The lifting function of the fixed rod can flexibly adjust the height of the support device to meet the precise requirements of the main beam height at different construction stages, making the entire construction process smoother. There is no need to replace the support device at different heights, thus improving construction efficiency. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a bridge construction main beam support device, including a support column 1. A motor 2 is fixedly connected inside the support column 1. The support column 1 serves as the main structure of the entire support device, playing a crucial role in supporting and connecting other components. The motor 2, fixed inside the support column 1, is the power source driving the rotation of an elliptical block 3. The drive end of the motor 2 is fixedly connected to the elliptical block 3, which rotates with the motor 2. During rotation, the elliptical block 3 contacts the side of multiple rotating rods 4, periodically pushing the rotating rods 4 due to changes in the elliptical contour. A fixing plate 20 is fixedly connected to the bottom of the support column 1. The fixing plate 20, connected to the support column 1, transmits the force on the bottom structure to the support column 1, ensuring the stability of the entire device. The fixing plate 20 has internal rotating connections... There are multiple rotating rods 4, and springs 9 are fixedly connected to the adjacent sides of each rotating rod 4. The springs 9 are connected to the adjacent sides of the rotating rod 4 and play a role in buffering and resetting. When the elliptical block 3 pushes the rotating rod 4, the spring 9 is pulled. When the elliptical block 3 leaves the pushing position, the spring 9 contracts its energy and pulls the rotating rod 4 to reset. The rotating rod 4 contacts the elliptical block 3 and rotates under the push of the elliptical block 3. The rotating rod 4 is connected to the fixed plate 20 through the spring 9 and is rotatably connected to the connecting rod 6. Through its own rotation, it drives the connecting rod 6 to move. Fixed columns 5 are fixedly connected inside each of the multiple rotating rods 4. The fixed columns 5 are connected to the inner wall of the fixed plate 20 on the upper and lower sides and play a role in positioning and strengthening the structural stability. Connecting rods 6 are rotatably connected to the distant sides of the rotating rods 4 and play a role in connecting and transmitting motion. As the rotating rod 4 rotates, the connecting rod 6 moves in coordination with the rotating rod 4 through the rotating shaft 7, and then drives the connecting plate 10 through its own movement. The rotating shaft 7 is fixedly connected to the adjacent side of the connecting rod 6. The rotating shaft 7 is connected between the connecting rod 6 and the rotating rod 4, so that the connecting rod 6 and the rotating rod 4 can rotate relative to each other. This ensures that the connecting rod 6 can flexibly follow the rotation of the rotating rod 4. The rotating shaft 8 is fixedly connected inside the connecting rod 6. The rotating shaft 8 is fixed inside the connecting rod 6 to provide support for the movement and structural stability of the connecting rod 6. It works in coordination with other components to ensure the smoothness of the connecting rod 6 during the transmission of movement. The connecting plate 10 is fixedly connected to the distant side of the connecting rod 6. As the connecting rod 6 moves, the connecting plate 10 slides in the fixed plate 20 and extends outward to increase the area of ​​the bottom support plate 17, thereby increasing the contact area between the support device and the ground and enhancing the support stability. The support column 1 is fixedly connected to the internal adjustment components for lifting.

[0033] Reference Figure 2 , Figure 3The adjustment assembly includes a protective shell 11, the left side of which is fixedly connected to the right side of the support column 1. The protective shell 11 is also a protective cover for the motor 12 and worm gear 13, protecting them from external environmental influences such as dust and moisture. The motor 12 is fixedly connected inside the protective shell 11. The motor 12 drives the worm gear 13 to rotate via its drive end, providing power for the rotation of the lead screw 15. The worm gear 13 is fixedly connected to the drive end of the motor 12 and meshes with a worm wheel 14, transmitting the rotational motion of the motor 12 to the lead screw 15. The meshing transmission between the worm gear 13 and the worm wheel 14 has a speed reduction and torque increase effect, enabling the lead screw 15 to obtain a suitable speed and sufficient torque, achieving precise lifting and lowering adjustment. In this section, a lead screw 15 is rotatably connected inside the support column 1. The lead screw 15 is fixedly connected to the worm gear 14 and rotates under the drive of the worm gear 14. The worm gear 14 is fixedly connected to the outside of the lead screw 15. The worm gear 14 meshes with the worm 13 and transmits the rotational motion of the worm 13 to the lead screw 15. The outside of the worm gear 14 is meshed with the outside of the worm 13. A connecting rod 16 is threadedly connected to the outside of the lead screw 15. As the lead screw 15 rotates, the connecting rod 16 slides up and down inside the support column 1, driving the support plate 17 to achieve lifting and lowering. Two sliding blocks 18 are fixedly connected to the outside of the connecting rod 16. The sliding blocks 18 are connected to the connecting rod 16 and assist the connecting rod 16 to slide smoothly inside the support column 1, ensuring the smoothness and stability of the lifting and lowering process of the support plate 17.

[0034] Reference Figure 3 , Figure 4The outer side of the elliptical block 3 contacts the adjacent side of multiple rotating rods 4. Due to the change in the elliptical contour, the elliptical block 3 periodically pushes the rotating rods 4, thereby achieving regular control of the movement of the rotating rods 4. It is an important component for adjusting the bottom structure. The upper and lower sides of multiple fixed columns 5 are fixedly connected to the inner wall of the fixed plate 20. The fixed plate 20 is connected to the support column 1, which transmits the force on the bottom structure to the support column 1, ensuring the stability of the entire device. The upper and lower sides of multiple rotating rods 4 are slidably connected to the inner wall of the fixed plate 20. The upper and lower sides of multiple connecting rods 6 are also slidably connected to the inner wall of the fixed plate 20. The connecting rods 6 drive the connecting plate 10 through their own movement, thereby realizing the extension or retraction of the bottom support plate 17. It is a key component for transmitting motion. The adjacent sides of multiple springs 9 are fixedly connected to the distant sides of the fixed plate 20. When the springs 9 release energy, they pull the rotating rods 4 to reset. The rotating rod 4 can work continuously and stably under the periodic action of the elliptical block 3. The fixed plate 20 is internally slidably connected to the outside of the two connecting plates 10. The support column 1 has two slots 19 inside, which position and fix the components inside the support column 1, ensuring the accurate relative position of each component during movement and preventing component displacement from affecting the normal operation of the device. The sliding block 18 is externally slidably connected to the inside of the support column 1. The top of the connecting rod 16 is fixedly connected to the support plate 17. After the support plate 17 is raised and lowered by the adjustment component, the support plate 17 provides a stable support plane for the main beam of the bridge construction, ensuring the stability and safety of the main beam during construction. The connecting rod 16 is externally slidably connected to the inside of the support column 1. The connecting rod 16 slides up and down in the support column 1, driving the support plate 17 to achieve the raising and lowering action. The rear side of the worm gear 13 is rotatably connected to the inside of the protective shell 11. The connecting rod 16 has a groove inside.

[0035] Working principle: Motor 1 2 is installed inside support column 1, driving elliptical block 3 to rotate. When elliptical block 3 rotates, its contour changes periodically, pushing rotating rod 4, causing rotating rod 4 to rotate around its connection point with fixed plate 20. When rotating rod 4 rotates, it drives connecting rod 6 to move. Rotating shaft 2 8 ensures the smoothness of the movement of connecting rod 6. Connecting rod 6 drives connecting plate 10 to slide within fixed plate 20. At the same time, spring 9 is stretched or contracted. The extension of connecting plate 10 can increase the bottom support area and enhance the stability of the device. By supporting and extending fixed plate 20, the contact area between the support device and the ground or foundation structure can be expanded, ensuring that the support device can effectively support the main beam under different terrain conditions.

[0036] The motor 12 inside the protective shell 11 serves as a power source, driving the worm gear 13 to rotate. The worm gear 13 meshes with the worm wheel 14, transmitting the rotational motion of the motor 12 to the lead screw 15, providing the lead screw 15 with a suitable speed and sufficient torque. The lead screw 15 rotates inside the support column 1, causing the connecting rod 16 to slide up and down. The sliding block 18 outside the connecting rod 16 assists it in sliding smoothly inside the support column 1, ultimately achieving the lifting and lowering adjustment of the support plate 17. The lifting function of the fixed rod can flexibly adjust the height of the support device to meet the precise requirements of the main beam height at different construction stages, making the entire construction process smoother, eliminating the need to replace support devices of different heights, and improving construction efficiency.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
