Further, the description involving "first", "second", etc. in the application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.

[0046] As shown in Figures 1-9 The present embodiment provides a turnover arc gate facilitating bearing replacement, which comprises a civil structure 1, an arc gate body 2, a supporting mechanism 3, a hydraulic cylinder, a bottom sill and a bearing 5 replacement device. The supporting mechanism 3 is fixedly connected with the arc gate body 2 and hinged with the civil structure 1. The gate bearing replacement device comprises a rotating shaft 4 and the bearing 5. The rotating shaft 4 is arranged at the hinge joint of the supporting mechanism 3 and the civil structure 1 and fixedly connected with the civil structure 1. The bearing 5 is located between the rotating shaft 4 and the supporting mechanism 3. The bearing 5 has a taper, which can be more conveniently removed from or moved into the rotating shaft 4 and the supporting mechanism 3 under the action of an external force.

[0047] For the turnover arc gate, the embodiment provides a turnover arc gate structure as follows: the civil structure 1 is arranged on the left and right sides of the arc gate body 2, the bottom sill is arranged below the arc gate body 2, the supporting mechanism 3 is fixedly connected with the arc gate body 2 and is hinged with the civil structure 1, the hydraulic cylinder is horizontally fixed on the civil structure 1, the piston rod of the hydraulic cylinder is hinged with the supporting mechanism 3, the arc gate body 2 is in a vertical state when closing water, and the arc gate body 2 is rotated downward to a horizontal state or upward to a horizontal state under the driving of the hydraulic cylinder when being opened.

[0048] Specifically, the arc gate body 2 is a hollow box structure surrounded by a circular arc surface arranged on the top and planes arranged on the bottom and the two sides respectively, the supporting mechanism 3 includes a hinge and two supporting arms which are symmetrically fixed on the two sides of the bottom plane of the arc gate body 2, the hinge is fixed on the civil structure 1 on the left and right sides of the arc gate body 2 respectively, the supporting arm is rotationally connected with the corresponding hinge, the axis of the circular arc surface of the arc gate body 2 is coaxial with the hinge, the supporting arm is in the shape of a right triangle, one of the right angles is fixedly connected with the arc gate body 2, when the arc gate body 2 is in a vertical or downward horizontal state, the piston rod of the hydraulic cylinder is hinged with the other right angle of the supporting arm at a relatively far end from the arc gate body 2, when the arc gate body 2 is in an upward horizontal state, the piston rod of the hydraulic cylinder is hinged with the other right angle of the supporting arm at a relatively near end from the arc gate body 2.

When the bearing 5 is replaced, the arc gate body 2 is controlled to be in an upward horizontal state through the piston rod of the hydraulic cylinder, the four locking oil cylinders 7 drive the locking pins to be inserted into the corresponding locking holes 8, so that the positions of the two-way turnover gate on the two sides are fixed and kept on the installation reference position. Unlike when the hinge joint is replaced, only one set of the locking oil cylinder 7 and the locking hole 8 combined with the hinge can fix the single-side gate, and since the gate is large in size and heavy in weight, the hydraulic cylinder cannot provide sufficient supporting force when the bearing 5 of the hinge joint is replaced. In addition, the bearing 5 needs to be accurately positioned when being replaced, otherwise the bearing 5 cannot be moved in and out. Therefore, the gate bearing replacement device provided in the embodiment is provided with four sets of the locking oil cylinder 7 and the locking hole 8, and the position error of the gate when being fixed can be adjusted through the screws on the locking seat, so that the accurate fixation of the gate can be realized.

Specifically, the steps for replacing the bearing 5 are as follows:
