Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, specifically to a planar rotation support device that facilitates bridge posture adjustment. Background Technology

[0002] With the development of my country's highway transportation industry, more and more newly built bridges need to cross existing railways or highways. In order to reduce the impact of bridge construction on traffic operations, bridge rotation construction technology has been widely used. The requirements for precision and efficiency in the bridge construction process are getting higher and higher. In particular, in terms of bridge posture adjustment, stable and efficient support devices are crucial. The core component in rotation construction is the rotation ball joint device, which requires support devices to support the ball joint device.

[0003] A search revealed a high-load-bearing capacity rotating bearing for assisting bridge attitude adjustment, disclosed in publication number CN214459733U. The bearing includes a top plate and a bottom plate. The convex spherical surface of the bottom surface of the top plate engages with the concave spherical surface of the top surface of the bottom plate. The central groove of the convex spherical surface engages with the central convex shaft of the concave spherical surface. A leveling mechanism is connected to the bottom of the bottom plate. The leveling mechanism includes a leveling steel plate and leveling components. Friction layer I on the surface of the convex spherical surface and friction layer II on the surface of the concave spherical surface constitute a spherical friction pair. Friction layer I may be a polished layer, a chrome-plated layer, or a stainless steel-coated layer. Friction layer II is a Cu-PTFE metal composite material layer, which may be an integral layer or a split layer. The circumference of the convex shaft is covered with a Cu-PTFE metal composite material layer. The top surface of the top plate is provided with circumferential reinforcing ribs and radial reinforcing ribs. The rotating bearing is small in size, low in cost, convenient to process and transport, and easy to install, position and level on site. The spherical friction pair has high load-bearing capacity and small compression deformation, and the bearing has good rotational stability. In this application, the bridge attitude is adjusted by connecting rod and ball joint device, which makes it difficult to make small adjustments to the bridge position and ultimately affects the accuracy of bridge attitude adjustment.

[0015] Working Principle: When the device is needed, firstly, a support frame, support seat one, and support seat two are erected. Support seat two, with its ball bearings, supports the bridge. While supporting the bridge, support seat one, along with flange plate one, moves downwards. As flange plate one moves downwards, it causes sliding rod pair one, hinge block two, and connecting rod two to rotate. The rotation of connecting rod two causes hinge block one to slide against the outer wall of sliding rod two, absorbing the impact force generated by the bridge support. Simultaneously, support seat two compresses spring one and telescopic rod one. Spring one and telescopic rod one, along with a moving block, slide inside the support frame, further buffering the impact force generated by the bridge and improving the service life of the support frame. When the bridge tilt angle needs to be adjusted, motor two is started, driving the worm gear to rotate. The worm gear drives the worm wheel and rotating rod to rotate. The rotating rod's rotation drives the drive gear to rotate, causing the drive gear to move the rack upwards. As the rack moves upwards, it causes the moving rod to slide inside the fixed rod. The moving rod pushes hinge block one, which in turn drives the push plate to rotate inside support seat one, thus tilting the bridge. When the bridge needs to be rotated, the infrared sensor first transmits a signal to the controller. The controller then starts the vehicle, which moves along the tracks with the fixed base and ball joint. By rotating handle two, the insert rod rotates inside the fixed sleeve two, extending into the base and securing it. When the base, along with the mounting plate, moves directly under the bridge, the support plate is pulled to move it. Then, the screw is rotated, causing the support legs to contact the ground and secure the vehicle. Next, multiple connecting bolts inside the connecting plate connect to the inside of the bridge. Then, motor one is started, rotating gear two, which in turn rotates gear one. Gear one rotates the rotating rod and ball joint, causing the bridge to rotate in a planar angle. When a fine-tuning of the bridge's angle is needed, rotating handle one causes the slider to impact the fixed block connected to connecting block one. The kinetic energy generated by the impact is transferred to connecting rod one, causing the first and second bevel gears to rotate. The first bevel gear rotates gear three, which in turn rotates gear one and the rotating rod, thus fine-tuning the angle of the ball joint and the connected bridge.

[0016] This invention provides a planar rotation support device that facilitates bridge attitude adjustment. It offers the following advantages: 1. This invention, through the cooperation of motor one, gear two, gear three, bevel gear one, bevel gear two, connecting rod, connecting block one, connecting shaft, connecting block two, and handle one, achieves the conversion of impact kinetic energy into axial movement kinetic energy of the rotating rod, realizing the function of micro-force application and micro-adjustment of the ball joint position. It solves the problem that it is difficult to achieve micro-adjustment of the bridge position by using connecting rod and ball joint device to adjust the bridge posture, which is easy to affect the accuracy of bridge posture adjustment.

[0017] 2. This invention facilitates the connection and fixation of the base through the cooperation between the support rod, fixing sleeve one, fixing sleeve two, insertion rod, and handle two. The modular design makes the device easy to assemble and disassemble, and convenient for rapid deployment and movement. It is suitable for bridges of different types and sizes. Through the cooperation between the lifting plate, hydraulic rod, vehicle body, track, controller, infrared sensor, connecting plate, support plate, screw, and outriggers, it facilitates movement and transportation with ball joints, thereby improving operational efficiency.

[0018] 3. This invention, through the cooperation between the bracket, moving block, telescopic rod one, spring one, telescopic rod two, spring two, support seat one, support seat two, and ball bearings, achieves the effect of absorbing the impact force of the bridge on the support frame, thereby improving the service life of the planar support frame. Through the cooperation between the base plate, push plate, motor two, worm gear, fixed block, rotating rod, worm wheel, drive gear, support rod, rack, moving rod, and hinge block, it realizes the function of fine adjustment of the vertical angle of the bridge, which facilitates the improvement of the accuracy and speed of subsequent bridge installation.

This series of actions realizes the adjustment of the bridge's tilt angle, meeting the needs of different scenarios. In addition, when support base 43 is under pressure, it squeezes spring 39 and telescopic rod 38. These two structures drive moving block 37 to slide inside bracket 36. At the same time, telescopic rod 40 and spring 41 also work together to further buffer the impact force generated by the bridge. This design not only improves the durability of support frame 35 but also ensures the stability of the bridge in various environments.
