Description

Technical Field

[0001] The invention relates to the technical field of swivel beams, and in particular to a swivel support structure and a swivel method for swivel beams. Background Art

[0002] A rotating beam is a bridge constructed by the rotation method. Bridge rotation construction refers to a construction method in which the bridge structure is formed (cast or spliced) at a non-design axis position and then rotated into place. It can transform operations over obstacles into operations on the shore or near the ground.

[0003] During the rotation of the existing rotating bridge, due to the heavy weight of the piers and the bridge, generally 20,000 to 30,000 tons, the rotating bridge and the piers have a large inertia. Often after the rotation force on the support legs stops, the piers and the bridge will still rotate to a certain angle. The angle of rotation of the bridge is not accurate, resulting in the bridge of the rotating bridge being unable to accurately dock with the viaducts on both sides. There is a certain inclination angle between the viaducts and the bridge on both sides of the bridge, which often needs to be repaired with steel bars and concrete. At the same time, before the construction of the rotating bridge, the corresponding rotating bridge slideway needs to be installed in the axial position. The traditional rotating bridge slideway structure is assembled by workers by welding steel parts. However, the assembly of the rotating bridge slideway structure by welding has complicated operation steps, requires many auxiliary tools, and is cumbersome to install. For this reason, we propose a rotating support structure and rotation method for a rotating beam. Summary of the invention

[0017] S1: First, fix the cap threaded pipe in the four openings reserved in the middle of the upper side of the cement bottom pier where the rotating beam is installed, and then thread the four threaded columns into the inside of the four cap threaded pipes. After the threaded connection, place the support frame on the upper ends of the four chassis, adjust the height of the four threaded columns after placement to level the support frame, and weld the support frame to the upper ends of the four chassis after leveling;

[0018] S2: After the support frame is welded, the lower ball joint is welded on the upper part of the support frame. After welding, the pin shaft is fixed inside the upper ball joint shell and inserted into the opening reserved in the middle of the lower ball joint. After insertion, the mirror ball disc inside the ball joint shell fits with the sliding silicone grease.

[0019] S3: After the mirror ball disc is fitted with the sliding silicone grease, eight evenly distributed slide plates are placed inside the annular groove reserved on the upper side of the cement bottom pier. After placement, the card grooves set on the sides of the eight slide plates are connected to the card plates, and then the eight limit blocks fixed on the lower sides of the eight slide plates are clamped into the inside of the limit grooves opened in the annular groove, and then the remaining eight slide plates are connected. After connection, the evenly distributed support rods fixed on their lower sides are clamped into the inside of the corresponding fastening grooves. After connection, the card column on the upper side of the slide plate on the lower side enters the inside of the fastening hole opened on the circumferential surface of the support rod under the action of the second spring connected to it. In this case, the upper and lower sixteen slide plates can be firmly connected. After connection, the four slide plates are placed above the eight slide plates on the upper side;

[0020] S4: After the four slide plates are placed, concrete support rods are poured inside the supporting steel pipes on the upper side thereof, and then a concrete rotating seat is poured between the connecting plate and the evenly distributed pouring steel bars on the upper side thereof, so that the concrete rotating seat and the four concrete support rods are connected after pouring;

[0021] S5: After the concrete rotating seat is poured, a rotating beam is constructed on its upper side. After the construction is completed, the U-shaped clamping rod is pulled out to separate the upper end from the clamping hole. After separation, the swivel is rotated to rotate the baffle. At this time, the rotation angle of the baffle is observed through a circular measuring ruler. When it reaches the position to which the rotating beam needs to be rotated, the upper end of the U-shaped clamping rod is connected to the corresponding clamping hole. After connection, the swivel is fixed, thereby fixing the baffle;

[0022] S6: After the baffle is fixed, the upper ball joint housing can be moved to rotate, thereby causing the swivel beam to rotate. During the rotation process, the fixed plate will be driven to rotate. When the fixed plate and the baffle are in contact, the rotation of the swivel beam can be completed.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the rotation support structure and rotation method for the swivel beam have the following advantages:

[0024] By setting a limit assembly, before the swivel beam on the upper side of the concrete base is rotated, the U-shaped clamping rod can be pulled out to separate its upper end from the clamping hole. After separation, the swivel ring is turned to rotate the baffle. At this time, the rotation angle of the baffle is observed through a circular measuring ruler. When it reaches the position to which the swivel beam needs to be rotated, the upper end of the U-shaped clamping rod is connected to the corresponding clamping hole. After the connection, the swivel ring is fixed to fix the baffle. After the baffle is fixed, the upper ball joint shell can be rotated. When the fixing plate fixed on its surface fits with the baffle, the rotation of the swivel beam can be completed, thereby avoiding the swivel beam from deviating. By setting a slideway assembly and a fixing assembly, eight evenly spaced parts can be placed inside the annular groove reserved on the upper side of the cement bottom pier during use. The distributed slide plates are placed so that the slots set on the sides of the eight slide plates are connected to the slots, and then the eight limit blocks fixed on the lower sides of the eight slide plates are inserted into the limit slots opened in the annular groove, and then the remaining eight slide plates are connected. After the connection, the evenly distributed support rods fixed on their lower sides are inserted into the corresponding fastening grooves. After the connection, the card column on the upper side of the slide plate on the lower side enters the fastening hole opened on the circumferential surface of the support rod under the action of the second spring connected to it. In this case, the upper and lower sixteen slide plates can be firmly connected. After the connection, the four slide plates are placed above the eight slide plates on the upper side. In this case, the laying of the slide can be completed, which is extremely convenient. BRIEF DESCRIPTION OF THE DRAWINGS

10. A method for rotating a rotating support structure for a rotating beam, characterized in that: The following steps are involved: S1: First, fix the cap threaded pipe in the four openings reserved in the middle of the upper side of the cement bottom pier where the rotating beam is installed, and then thread the four threaded columns into the inside of the four cap threaded pipes. After the threaded connection, place the support frame on the upper ends of the four chassis, adjust the height of the four threaded columns after placement to level the support frame, and weld the support frame to the upper ends of the four chassis after leveling; S2: After the support frame is welded, the lower ball joint is welded on the upper part of the support frame. After welding, the pin shaft is fixed inside the upper ball joint shell and inserted into the opening reserved in the middle of the lower ball joint. After insertion, the mirror ball disc inside the ball joint shell fits with the sliding silicone grease. S3: After the mirror ball disc is fitted with the sliding silicone grease, eight evenly distributed slide plates are placed inside the annular groove reserved on the upper side of the cement bottom pier. After placement, the card grooves set on the sides of the eight slide plates are connected to the card plates, and then the eight limit blocks fixed on the lower sides of the eight slide plates are clamped into the inside of the limit grooves opened in the annular groove, and then the remaining eight slide plates are connected. After connection, the evenly distributed support rods fixed on their lower sides are clamped into the inside of the corresponding fastening grooves. After connection, the card column on the upper side of the slide plate on the lower side enters the inside of the fastening hole opened on the circumferential surface of the support rod under the action of the second spring connected to it. In this case, the upper and lower sixteen slide plates can be firmly connected. After connection, the four slide plates are placed above the eight slide plates on the upper side; S4: After the four slide plates are placed, concrete support rods are poured inside the supporting steel pipes on the upper side thereof, and then a concrete rotating seat is poured between the connecting plate and the evenly distributed pouring steel bars on the upper side thereof, so that the concrete rotating seat and the four concrete support rods are connected after pouring; S5: After the concrete rotating seat is poured, a rotating beam is constructed on its upper side. After the construction is completed, the U-shaped clamping rod is pulled out to separate the upper end from the clamping hole. After separation, the swivel is rotated to rotate the baffle. At this time, the rotation angle of the baffle is observed through a circular measuring ruler. When it reaches the position to which the rotating beam needs to be rotated, the upper end of the U-shaped clamping rod is connected to the corresponding clamping hole. After connection, the swivel is fixed, thereby fixing the baffle; S6: After the baffle is fixed, the upper ball joint housing can be moved to rotate, thereby causing the swivel beam to rotate. During the rotation process, the fixed plate will be driven to rotate. When the fixed plate and the baffle are in contact, the rotation of the swivel beam can be completed.
