Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a connection structure between a cap and a rotation pier for bridge beam construction. Background Art

[0002] There are roads on both sides of some parts of the bridge construction site, and the road traffic is very congested during the day and at night. The bridge construction must be carried out while ensuring the normal use of the roads on both sides, which brings difficulties to the construction. In order to meet this challenge, a special bridge pier construction method is needed, that is, the bridge pier rotation construction method.

[0003] After searching, the Chinese patent with publication number CN110117936A discloses a swivel device for bridge piers, including a rotating part, a reaction part and an anti-overturning part; the rotating part includes a swivel jack, a steel strand for swivel, a lower steel plate of a turntable, a polytetrafluoroethylene plate, an upper steel plate of a turntable and a rotating shaft; the reaction part includes a reaction pier; the anti-overturning part includes an anti-overturning clamp and a cement track; the lower end of the reaction pier is fixed to the ground, with the side with the stiffening rib facing the direction of the pier, the swivel jack is installed on the reaction pier away from the pier, and the cement track is cast on the ground concentrically with the pier.

[0004] However, the above invention has the following disadvantages:

[0005] Currently, spherical joints are commonly used in bridge rotation construction to connect the abutment and the pier. Although spherical joints are typically made of self-lubricating, wear-resistant materials, boundary lubrication failure is highly likely to occur on the contact surface under the specific operating conditions of high pressure and low rotation speed. This failure directly leads to a sharp increase in the friction coefficient between the contact surfaces. To overcome the sudden increase in frictional resistance and achieve pier rotation, a high-power jack system must be used to provide the enormous rotational torque. This not only significantly increases the purchase and operation costs of the rotation equipment, but also significantly increases energy consumption during construction. Summary of the Invention

[0020] The present invention provides a connection structure between a cap and a swivel pier for bridge beam construction through improvements. Compared with the prior art, the present invention has the following improvements and advantages:

[0021] Firstly, the present invention can reduce the friction of the twisting ball when it rotates by setting the lubrication mechanism and the transmission mechanism. At the same time, when the twisting ball rotates, the twisting ball will also drive the rotating shaft to rotate, and the rotating shaft will then drive the transmission gear ring to rotate. The transmission gear ring is engaged with the transmission gear 1, thereby driving the transmission gear 1 to rotate. The transmission gear 1 then drives the transmission gear 2 to rotate through the installation shaft. A transmission belt is set between the multiple transmission gears 2, and the bottom of the driving shaft is also installed with the transmission gear 2, which can then drive the transmission belt at the bottom of the driving shaft to rotate through the transmission belt. The transmission belt drives the driving When the shaft rotates, the drive shaft and the transmission rod are threadedly connected, and the transmission rod moves upward inside the inner tube, so that the piston plate can move upward inside the inner tube. The movement of the piston plate pushes the lubricating oil inside the inner tube upward, so that the lubricating oil moves to the position of the supporting ball through the circular hole on the oil plate. At this time, the supporting ball will be coated with lubricating oil, and then the lubricating oil can be applied to the twisting ball through the rotation of the supporting ball, which can further reduce the friction generated during the rotation, thereby achieving the effect of making the pier body and the rotating bridge easier to rotate, reducing manpower or machine losses.

[0022] When the cam is released, the support rod is pulled out of the bearing block, and the support rod is pulled out of the bearing block, so that the support rod is separated from the outer ring, and the support rod moves downward without the support of the support ball. Then, the support rod is fitted with the bottom of the ball joint seat, and the support rod drives the rotating shaft rod to move downward, and the bottom of the rotating shaft rod moves downward at the bottom of the installation groove. When the support rod rotates, the limit block will also change from a position staggered with the limit groove to a corresponding position. After the support rod moves downward, the limit block will also move to the inside of the limit groove, thereby limiting the support rod and the rotating shaft rod together with the connecting block. At this time, the support rod cannot drive the rotating shaft rod to rotate inside the ball joint seat, thereby achieving the effect of quickly fixing the ball joint mechanism after rotation.

[0023] Third: The present invention supports the pier body and the rotating bridge through the setting of the supporting mechanism. The support rod 1 and the support rod 2 support the pier body and the rotating bridge. When the pier body and the rotating bridge rotate, the slip ring will also rotate inside the slide groove, so that the support rod 1 and the support rod 2 can support the pier body and the rotating bridge even when the pier body and the rotating bridge rotate.

[0024] Fourthly: In the present invention, the friction force generated by the rotation of the slip ring inside the slide groove can be reduced by the ball bearings, and the friction loss between the slip ring and the base can be reduced. At the same time, when the pier body and the rotating bridge are rotated, the positioning block can be first taken out from the inside of the positioning groove. At this time, the connecting block 2 can be separated from the slip ring, and then the support rod 1 and the support rod 2 can be removed from the reinforcement 1 and the reinforcement 2. Then the insertion rod can be removed, and the reinforcement 1 and the reinforcement 2 can be removed from the pier body, so that it is convenient to support the pier body when the rotation is achieved, and it is also convenient to dismantle after the rotation.

[0046] Specific implementation steps: Through the setting of the ball joint mechanism, the pier body 2 is connected to the ball 6 through the ball rod 8. When rotation is required, the pier body 2 and the rotating bridge 3 rotate, and the ball 6 rotates inside the ball joint lower seat 4, thereby reducing the friction force when the pier body 2 and the rotating bridge 3 rotate.

[0047] At the same time, through the setting of the lubrication mechanism and the transmission mechanism, the setting of the support ball 13 can reduce the friction force when the ball 6 rotates. At the same time, when the ball 6 rotates, the ball 6 will also drive the rotating shaft rod 10 to rotate, and the rotating shaft rod 10 will then drive the transmission gear ring 49 to rotate. The transmission gear ring 49 is engaged with the transmission gear 19, thereby driving the transmission gear 19 to rotate. The transmission gear 19 then drives the transmission gear 20 to rotate through the installation shaft 18. A transmission belt 21 is set between the multiple transmission gears 20, and the bottom of the drive shaft 17 is also installed with a transmission gear 20, which can then drive the transmission belt 21 at the bottom of the drive shaft 17 to rotate through the transmission belt 21. The transmission belt 21 drives the drive shaft 1 7 rotates, the drive shaft 17 is threadedly connected to the transmission rod 16, and the transmission rod 16 moves upward inside the inner tube 12, so that the piston plate 14 can move upward inside the inner tube 12. The movement of the piston plate 14 pushes the lubricating oil inside the inner tube 12 upward, so that the lubricating oil moves to the position of the support ball 13 through the circular hole on the oil plate 15. At this time, the support ball 13 will be coated with lubricating oil, and then the lubricating oil can be applied to the stranding ball 6 through the rotation of the support ball 13, which can further reduce the friction between the stranding ball 6 and the support ball 13 during contact, thereby achieving the effect of making it easier for the pier body 2 and the rotating bridge 3 to rotate, reducing manpower or machine loss.
