Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering construction, and particularly relates to a turnover adjusting device for a hollow pier formwork. Background Art

[0002] Hollow piers are mainly divided into three categories: reinforced concrete thin-walled piers, double-wall piers, and V-shaped piers. Their characteristics are that the length in the transverse bridge direction is basically the same as that of other types of piers, but the length in the longitudinal bridge direction is very small. Their advantages are that they can save materials, reduce the self-weight of the pier, and at the same time, double-wall piers can increase the stiffness of the pier, reduce the negative moment at the main beam support point, and enhance the beauty of the bridge; V-shaped piers can indirectly reduce the span of the main beam, reduce the mid-span moment, and at the same time have some characteristics of arch bridges, making them more suitable for the construction of long-span bridges; in the current construction of hollow pier projects, the turnover of formwork between adjacent hollow piers has not been effectively improved. The formwork is divided into inner and outer formworks, and after the concrete is poured, it is demolded. After demolding, the previous formwork is turned to the adjacent pier, which greatly affects the construction progress. Summary of the Invention

[0003] The purpose of the utility model is to provide an adjusting device with a simple structure, convenient operation, and capable of effectively improving the formwork turnover efficiency between adjacent hollow piers.

[0004] The technical solution of the utility model is as follows:

[0005] A turnover adjusting device for a hollow pier formwork includes a formwork turnover box body. An installation groove is opened inside the formwork turnover box body. One side of the bottom of the installation groove is fixedly connected with a first motor. One end of the first motor is connected to one end of a first rotating rod. The other end of the first rotating rod is connected to a driving gear. The driving gear is also connected to a first gear belt. Two sides of the bottom end of the installation groove are respectively provided with first support frames. The first support frames are connected to a second rotating rod through bearings. A driven gear is arranged on the second rotating rod. The driven gear is connected to the first gear belt. A gear runner is also arranged on the second rotating rod. The gear runner is connected to a second gear belt.

[0006] Further, fixing blocks are respectively arranged on two sides of the bottom end of the formwork turnover box body. One side of the bottom end of the fixing block is connected to a first hydraulic rod through a hinge. The first hydraulic rod is also connected to a box door through a hinge. Connecting rods are fixedly arranged at the bottom end of the fixing block through hinges. The bottom end of the fixing block is connected to a second hydraulic rod through hinges. One end of the second hydraulic rod is connected to the connecting rod through a hinge. One end of the connecting rod is connected to the box door through a hinge.

[0007] Further, support blocks are respectively arranged at the four corners of the bottom of the formwork turnover box body. Suspension rings are fixedly arranged at the four corners of the top of the formwork turnover box body.

[0008] Further, a plurality of lighting lamps are provided at the top of the installation groove.

[0009] Further, both the driving gear and the driven gear are engaged with the first gear belt, and the second gear belt is engaged with the gear runner.

[0010] Advantages of the present utility model:

[0011] 1. The turnover adjustment device for the hollow pier formwork of the present utility model uses the cooperation among the first motor, the first rotating rod, the driving gear, the first gear belt, the second rotating rod, the driven gear, the gear runner, and the second gear belt. When the formwork between adjacent piers needs to be turnover-adjusted during the construction of the hollow pier, the first hydraulic rod can be operated to drive the box door to flip so that it reaches the position for turnover adjustment of the hollow pier formwork. The box door is lifted or lowered to the specified position by the second hydraulic rod, and the formwork to be turnover-adjusted is moved into the formwork turnover box body. The driving gear is rotated by the first motor, so that the first gear belt drives the driven gear to rotate, then the second rotating rod rotates to drive the gear runner to rotate, and thus the formwork to be turnover-adjusted is transported to the adjacent pier through the second gear belt. The device is simple and easy to operate for turnover adjustment of the formwork. At the same time, working inside the formwork turnover box body can effectively protect the safety of construction workers and improve construction safety.

[0012] 2. The turnover adjustment device for the hollow pier formwork of the present utility model uses lifting rings, which are convenient for disassembly and assembly and for the crane to move and transport. Description of the drawings
