Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction and relates to a beam body deviation rectification and reset mechanism for bridges. Background Art

[0002] Bridges play an extremely important role in the rapidly developing modern society. However, due to design factors, construction factors, usage factors, natural factors, etc., bridges are extremely prone to deformation, resulting in lateral or longitudinal offsets, causing problems such as beam body damage, pier deviation, or bearing damage, and even posing a risk of beam body falling. Therefore, it is necessary to promptly rectify and reset the beam body with lateral or longitudinal offsets. Currently, the common method for rectifying and resetting the beam body laterally or longitudinally is to use the jacking and translation deviation rectification technology. First, set up the support, and then use vertical jacks for jacking and horizontal jacks for translation to reset the beam body. This method has a complex structure and cumbersome steps, requiring a complex vertical support system, a horizontal reaction force system, a large number of jack synchronization systems, etc., and also requires a large amount of manpower, energy, time, and economic costs. Therefore, a beam body deviation rectification and reset mechanism for bridges that integrates a support system, a lateral displacement system, and a jack synchronization system should be provided. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a beam body deviation rectification and reset mechanism for bridges, which solves the problems of complex structure and high cost existing in the existing bridge deviation rectification mechanism.

[0004] The technical solution adopted by the utility model is that the beam body deviation rectification and reset mechanism for bridges includes a deviation rectification and jacking device, the deviation rectification and jacking device is surrounded within a deviation rectification support, and a support base is provided at the bottom of the deviation rectification support.

[0005] The characteristics of the utility model further lie in that:

[0006] The deviation rectification and jacking device includes a lower platform of the deviation rectification device. The center of the upper surface of the lower platform of the deviation rectification device is connected with a hydraulic cylinder. The end of the piston rod of the hydraulic cylinder is connected to the lower platform of the deviation rectification device, and the cylinder body of the hydraulic cylinder is connected to the center of the bottom of the upper platform of the deviation rectification device. A transverse and longitudinal deviation rectification device is connected above the upper platform of the deviation rectification device.

[0007] The transverse and longitudinal deviation rectification device includes a support frame. One side of the support frame is provided with an x-direction horizontally extending hydraulic cylinder. The end of the piston rod of the x-direction horizontally extending hydraulic cylinder is connected to the middle part of a U-shaped x-direction slider. One side of the x-direction slider is connected with a y-direction horizontally extending hydraulic cylinder through a bolt, and the end of the piston rod of the y-direction horizontally extending hydraulic cylinder is connected to a y-direction slider;

[0008] The bottom of the support frame is provided with a longitudinally extending hydraulic cylinder, and the longitudinally extending hydraulic cylinder is connected to the upper surface of the upper platform of the deviation rectification device through a connecting plate.

[0011] The number of vertically extending hydraulic cylinders is four. The cylinder bodies of the four vertically extending hydraulic cylinders are respectively connected to the support frame, and the end parts of the piston rods of the vertically extending hydraulic cylinders are connected to the connecting plate.

[0012] The deviation correction bracket includes a number of square steel frame assemblies connected in sequence along the vertical direction.

[0013] Each square steel frame assembly includes a square steel frame. Hinges are respectively provided on the upper surfaces of the four side frames of the square steel frame, and connecting blocks are respectively provided at the four vertices of the square steel frame. The square steel frames are connected by bolts through the connecting blocks.

[0029] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0030] Example 1

[0031] The beam deviation correction and reset mechanism for bridges of the present utility model, as Figure 1 shown, includes a deviation correction bracket. A bracket base 3 is provided at the bottom of the deviation correction bracket, and a deviation correction and jacking device 1 is provided inside the deviation correction bracket.

[0032] Example 2

[0033] As Figure 2 shown, the deviation correction and jacking device 1 includes a transverse and longitudinal deviation correction device 1-1, an upper platform 1-2 of the deviation correction device, a hydraulic cylinder 1-3, and a lower platform 1-4 of the deviation correction device. The upper platform 1-2 of the deviation correction device and the lower platform 1-4 of the deviation correction device are connected by a hydraulic cylinder 1-3, and they assist each other to make the entire deviation correction device climb to the top of the deviation correction bracket 2.

[0034] Figure 3(a) is an axonometric view of the transverse and longitudinal deviation correction device 1-1, and Figure 3(b) is a top view of the transverse and longitudinal deviation correction device 1-1;

[0035] Example 3

[0036] The horizontal and vertical deviation rectifying device 1-1 includes an x-direction horizontal extension hydraulic cylinder 1-1-1, a y-direction slider 1-1-2, an x-direction slider 1-1-3, a y-direction horizontal extension hydraulic cylinder 1-1-4, a support frame 1-1-5, a longitudinal extension hydraulic cylinder 1-1-6, and a connecting plate 1-1-7.

[0037] On one side of the support frame 1-1-5, there are three x-direction horizontal extension hydraulic cylinders 1-1-1. The cylinder body of each x-direction horizontal extension hydraulic cylinder 1-1-1 is connected to the support frame 1-1-5 by bolts. The end of the piston rod of each x-direction horizontal extension hydraulic cylinder 1-1-1 is connected to the middle of the U-shaped x-direction slider 1-1-3. The end of the piston rod of the x-direction horizontal extension hydraulic cylinder 1-1-1 is welded to the x-direction slider 1-1-3. On one side of the x-direction slider 1-1-3, two y-direction horizontal extension hydraulic cylinders 1-1-4 are connected by bolts. The end of the piston rod of the y-direction horizontal extension hydraulic cylinder 1-1-4 is welded to the y-direction slider 1-1-2.

[0038] The cylinder bodies of the four longitudinal extension hydraulic cylinders 1-1-6 are respectively welded to the support frame 1-1-5. The end of the piston rod of the longitudinal extension hydraulic cylinder 1-1-6 is welded to the connecting plate 1-1-7. The connecting plate 1-1-7 is connected to the upper plane of the upper platform 1-2 of the deviation rectifying device by bolts. The upper platform 1-2 of the deviation rectifying device is mainly used to support the horizontal and vertical deviation rectifying device 1-1.

[0039] The upper platform 1-2 of the deviation rectifying device is welded by a square steel frame. A thick steel plate is welded on the top of the upper platform 1-2 of the deviation rectifying device. The lower plane of the upper platform 1-2 of the deviation rectifying device is connected to the cylinder body of the hydraulic cylinder 1-3 by bolts. These bolts are the key to the connection between the upper platform 1-2 of the deviation rectifying device and the hydraulic cylinder 1-3. The specific model needs to be selected according to the thrust and pull of the hydraulic cylinder 1-3 and the gravity of the entire deviation rectifying and lifting device 1, as well as the acting force between the horizontal and vertical deviation rectifying device 1-1 and the bridge beam body during deviation rectification. The lower platform 1-4 of the deviation rectifying device is welded by square steel pipes. A thick steel plate is welded on the upper surface of the lower platform 1-4 of the deviation rectifying device. And the piston rod of the hydraulic cylinder 1-3 is welded to the upper plane of the lower platform 1-4 of the deviation rectifying device.

[0040] The deviation rectifying bracket includes a number of square steel frame combinations 2 connected in sequence along the vertical direction, as Figure 4 shown. Each square steel frame combination 2 includes a square steel frame 2-1, a hinge 2-2, and a connecting block 2-3. Hinges 2-2 are respectively provided on the upper surfaces of the four side frames of the square steel frame 2-1. Connecting blocks 2-3 are respectively welded at the four vertices of the square steel frame 2-1.

[0041] The hinge leaf A of the hinge 2-2 is welded to the upper surface of the square steel frame A2-1. The hinge leaf B of the hinge 2-2 can rotate freely around the hinge rotating shaft. And the rotating shaft of the hinge 2-2 is aligned with the inner edge of the upper surface of the square steel frame 2-1.

[0042] Between each square steel frame 2-1, they are bolted together through a connecting block 2-3. The function of the entire deviation rectification support is to support the overall deviation rectification lifting device 1 to climb to the preset height.

[0043] As shown in Figure 5(a), when the deviation rectification lifting device 1 is in a stationary state, the hinge pieces A and B of the hinge 2-2 are unfolded at 180°.

[0044] As shown in Figure 5(b), when the deviation rectification lifting device 1 ascends from bottom to top, the hinge pieces A and B of the hinge 2-2 are at 90°. The function of the hinge 2-2 is to support the deviation rectification device 1 to climb to the top of the deviation rectification support. The deviation rectification support is longitudinally built, and by adjusting the number of square steel frames 2-1, deviation rectification supports with different preset heights can be built.

[0045] The working process of the beam deviation rectification and reset mechanism for the bridge of the present utility model is as follows: When the entire mechanism is installed, the overall deviation rectification lifting device 1 should be installed on the support base 3 first. Specifically: Place the lower platform 1-4 of the deviation rectification device on the upper surface of the support base 3, weld the end of the piston rod of the hydraulic cylinder 1-3 to the middle of the upper surface of the lower platform 1-4 of the deviation rectification device, and then connect the cylinder body of the hydraulic cylinder 1-3 to the bottom center of the upper platform 1-2 of the deviation rectification device, and the hydraulic cylinder 1-3 and the upper platform of the deviation rectification device are bolted together.

[0046] Install the four longitudinal hydraulic cylinders 1-1-6 of the horizontal and vertical deviation rectification device 1-1 on the upper surface of the upper platform 1-2 of the deviation rectification device and bolt them together. Then install the x-direction horizontal extension hydraulic cylinder 1-1-1, y-direction slider 1-1-2, x-direction slider 1-1-3, y-direction horizontal extension hydraulic cylinder 1-1-4, and support frame 1-1-5 respectively. Then continue to build the deviation rectification support. When it reaches the preset height, connect all the square steel frame assemblies 2 with bolts.

[0047] After the entire mechanism is installed, the piston rod of the hydraulic cylinder 1-3 in the deviation rectification lifting device 1 is in the retracted state. The initial state of the hinge 2-2 is as shown in Figure 5(b), that is, the hinge pieces A and B of the hinge 2-2 form an angle of 180°.

[0048] Start the deviation rectification lifting device 1, and the piston rod of the hydraulic cylinder 1-3 extends downward to push the upper platform 1-2 of the deviation rectification device upward (as shown in state (I) in Figure 6 When passing through the hinge 2-2 during the process of pushing the upper platform 1-2 of the deviation rectification device upward, push the hinge piece B of the hinge A2-2 upward to make it present 90° (as shown in Figure 6As shown in state (II), when the upper platform 1-2 of the deviation rectification device passes through the hinge 2-2, since the rotating shaft of the hinge 2-2 itself has a spring, the hinge 2-2 will return to its initial state without external force, making the angle between hinge piece A and hinge piece B of the hinge piece 2-2 180°, thus forming a supporting surface. After the upper platform 1-2 of the deviation rectification device passes through the hinge 2-2, the bottom of the upper platform 1-2 of the deviation rectification device will fall on the supporting surface formed by the hinge 2-2 (as shown in Figure 6 state (III). At this time, after the upper platform 1-2 of the deviation rectification device stabilizes, the inner rod of the hydraulic cylinder 1-3 contracts to pull the lower platform 1-4 of the deviation rectification device upward; during the process of pulling the lower platform 1-4 of the deviation rectification device upward, the lower platform 1-4 of the deviation rectification device will also contact the hinge 2-2. The change process of the hinge 2-2 during the contact process is the same as that of the upper platform 1-2 of the deviation rectification device contacting the hinge 2-2, that is, during the contact process between the lower platform 1-4 of the deviation rectification device and the hinge 2-2, the angle between hinge piece B and hinge piece A in the hinge 2-2 will also go through a change process from 180° to 90° to 180°. After the lower platform 1-4 of the deviation rectification device passes through the hinge 2-2, the bottom of the lower platform 1-4 of the deviation rectification device will also fall on the supporting surface formed by hinge piece A and hinge piece B in the hinge 2-2 (as shown in Figure 6 state (IV). Subsequently, the hydraulic cylinder 1-3 continues to push the upper platform 1-2 of the deviation rectification device upward, and the upper platform 1-2 and the lower platform 1-4 of the deviation rectification device repeat the above actions, finally sending the entire deviation rectification and lifting device 1 to the top of the deviation rectification support. After the deviation rectification and lifting device 1 stabilizes, longitudinal lifting and deviation rectification are carried out through the longitudinal extension hydraulic cylinder 1-1-6. After reaching the specified position, the x-direction slider 1-1-3 is controlled by the x-direction transverse extension hydraulic cylinder 1-1-1 to move in the x direction, and the y-direction slider 1-1-2 is controlled by the y-direction transverse extension hydraulic cylinder 1-1-4 to move in the y direction, so as to realize the lateral deviation rectification of the beam body. After the overall deviation rectification is completed, the inner rod of the longitudinal extension hydraulic cylinder 1-1-6 contracts to lower the beam. When the horizontal and vertical deviation rectification device 1-1 performs the deviation rectification work, it should be carried out when the entire deviation rectification device 1-1 stops climbing at the highest preset height of the deviation rectification support.
