Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a bridge pier top rotation construction structure. Background Art

[0002] With the rapid development of infrastructure construction in my country, the number of bridge projects across existing traffic lines is increasing. Bridges refer to buildings built over rivers, lakes, seas, mountain streams or poor geology, which enable pedestrians and vehicles to pass smoothly. They are an important part of modern transportation. During the construction of bridges, in order to speed up the construction, they will be built in sections. When the bridges are built in sections, the bridge rotation construction technology will be applied. That is, when the bridges are built in sections, one end of the prefabricated bridge is installed on the pedestal and then turned to complete the docking of the entire bridge.

[0003] Traditional rotation construction usually sets the hinge between the pier and the bottom of the pier, and then drives the bridge to rotate, thereby completing the rotation of the bridge body. However, due to the need to set the hinge on the top of the pier, the structural size of the pier needs to be designed to be larger, the excavation construction of the pier foundation will cause greater disturbance to the roadbed, and the swivel tonnage is large, and the swivel requires a larger power equipment drive, making the entire structure complex, construction difficult, and the project cost high.

[0027] like Figure 1-Figure 5 As shown, the utility model provides a bridge pier top rotation construction structure, including: a rotating flat hinge 101, a winch 104 and a traction cable 106, the rotating flat hinge 101 is arranged on the first pier 102, the top of the rotating flat hinge 101 is connected to the bottom end of the middle part of the bridge 103, and the bridge 103 can rotate relative to the first pier 102 through the rotating flat hinge 101; the winch 104 is arranged on the second pier 105 adjacent to the first pier 102; one end of the traction cable 106 is connected to the winch 104, and the other end of the traction cable 106 is connected to one end of the bridge 103.

[0028] The working principle of the above embodiment is briefly described:

[0029] The rotating hinge 101 is installed on the first pier 102. After the rotating hinge 101 is installed and calibrated to meet the accuracy, it is leveled. After leveling, epoxy mortar is poured into the gap, and dust prevention is done. The winch 104 is installed on the second pier 105 on the side where the rotating bridge 103 is in place. The traction cable 106 is installed on the winch 104. One end of the traction cable 106 is connected to the beam end of the rotating bridge 103, and the other end of the traction cable 106 is connected to the winch 104. The winch 104 is started according to the established power speed. The winch 104 drives the traction cable 106 to contract, and the traction cable 106 drives the bridge 103 connected thereto to rotate. The rotating hinge 101 can reduce the friction between the bridge 103 and the first pier 102 when the bridge 103 rotates. After the rotation operation of the bridge 103 is in place, the rotating hinge is removed after the pier top support is installed.

[0030] The bridge pier top rotation construction structure of the utility model can perform the bridge 103 rotation operation without the need for large power equipment to drive, and the entire structure is simple in construction and easy to construct. The rotating flat hinge 101 can be dismantled and reused after the construction is completed, which can effectively ensure the quality of the rotation construction and greatly reduce the construction cost.

[0031] On the basis of the above embodiments, in order to ensure the smooth rotation of the rotating flat hinge turntable 202, the stability of the rotation operation of the bridge 103 is ensured.

[0032] like Figure 4 and Figure 5 As shown, the rotating flat hinge 101 includes a rotating flat hinge base 201 and a rotating flat hinge turntable 202, wherein the rotating flat hinge base 201 is arranged at the top of the first pier 102, and a groove 203 is provided on the rotating flat hinge base 201, and the bottom end of the rotating flat hinge turntable 202 is pivotally connected to the groove 203, and the bottom end of the bridge 103 is connected to the top of the rotating flat hinge turntable 202.

[0033] When the traction rope 106 pulls the bridge 103 to rotate, the bridge 103 drives the rotating flat hinge turntable 202 to rotate, and the rotating flat hinge turntable 202 rotates in the groove 203 of the rotating flat hinge base 201. Under the guiding action of the groove 203, the rotation stability of the rotating flat hinge turntable 202 can be guaranteed, thereby ensuring the stability of the rotation operation of the bridge 103.

[0034] As a preferred solution, Figure 4 As shown, a bracket is provided at the lower end of the rotating flat hinge base 201, and the bracket includes a bottom plate 301 and a rib plate 302. The bottom plate 301 is connected to the top of the first bridge pier 102 through an anchor bolt 303, and the rib plate 302 is connected to the top of the bottom plate 301, and the top of the rib plate 302 is connected to the bottom end of the rotating flat hinge base 201. The rotating flat hinge 101 and the rotating flat hinge 101 bracket are welded in the factory and installed on the top of the rotating bridge pier on site. After installation, three-way adjustment is performed. The relative height difference of the edge of the rotating flat hinge 101 is less than 0.5mm, and the longitudinal and lateral errors of the center of the flat hinge are less than 1mm. By setting the bracket, the rotating flat hinge base 201 is connected to the first bridge pier 102 through the rib plate 302 and the bottom plate 301 of the bracket, which can facilitate the disassembly and installation of the rotating flat hinge base 201, and can improve the reliability of the connection of the rotating flat hinge base 201, thereby ensuring the stability of the rotation of the bridge 103.

[0035] As a preferred solution, Figure 4As shown, a slide plate 4 is provided in the groove 203, and the slide plate 4 abuts against the bottom end of the rotating flat hinge turntable 202, and the slide plate 4 is used to reduce the friction between the rotating flat hinge turntable 202 and the groove 203. By providing the slide plate 4, the friction between the rotating flat hinge turntable 202 and the groove 203 can be reduced when the bridge 103 rotates, thereby reducing the resistance of the bridge 103 when rotating and reducing the wear of the rotating flat hinge turntable 202.

[0036] As a preferred solution, Figure 4 As shown, the slide plate 4 is a polytetrafluoroethylene plate. Using the polytetrafluoroethylene plate as the slide plate 4 can not only reduce the friction between the rotating flat hinge turntable 202 and the groove 203, but also reduce the vibration of the rotating flat hinge turntable 202 during rotation, thereby preventing the bridge 103 from vibrating, thereby further ensuring the stability of the bridge 103 rotation.

[0037] As a preferred solution, Figure 2 and Figure 3 As shown, a bridge traction anchor 5 is provided at one end of the bridge 103, and the traction cable 106 is connected to one end of the bridge 103 through the bridge traction anchor 5. By providing the bridge traction anchor 5, the connection between the traction cable 106 and the bridge 103 can be improved, thereby further ensuring the stability of the bridge 103 when rotating.

[0038] As a preferred solution, Figure 1-Figure 3 As shown, a steering pulley 6 is provided on the first pier 102, and the traction rope 106 passes around the steering pulley 6. The steering pulley 6 is a fixed pulley, and the steering operation using the steering pulley 6 can ensure that the winch 104 works in a fixed direction, thereby improving the convenience of operation.

[0039] As a preferred solution, Figure 4 As shown, the rotating hinge is detachably connected to the first bridge pier 102. By arranging the rotating hinge 101 and the first bridge pier 102 to be detachably connected, the rotating hinge 101 can be removed after the construction is completed, so as to be reused when the bridge 103 turns next time, thereby reducing the construction cost of the bridge 103 turning.
