Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of overhauling the bottom pivot of a ship lock miter gate, in particular to a device for removing the hinge hole bolt of the bottom pivot of a ship lock miter gate. BACKGROUND

[0002] The bottom pivot of a certain ship lock miter gate is the movable joint part of the ship lock miter gate and, together with the top pivot part, supports the opening and closing fulcrum of the miter gate. The bottom pivot part not only needs to bear the overall weight of the miter gate, but also needs to ensure the flexible operation of the opening and closing of the miter gate. The miter gate leaf part can rotate around the bottom pivot as the fulcrum. The hinge hole bolt of the bottom pivot is the connecting bolt above the connecting bearing of the miter gate leaf and the bottom pivot. It mainly limits the horizontal displacement of the bearing of the bottom pivot on the miter gate leaf and provides protection for the positioning of the entire miter gate. The hinge hole bolt is generally set to 10-16 unequal bolts according to the size of the ship lock miter gate and the structure of the bottom pivot. However, 6-7 hinge hole bolts adopt an interference fit with the bottom pivot base of the miter gate, and the position is narrow and small, making it inconvenient to disassemble. SUMMARY

[0003] To solve the current technical problems, the main purpose of the utility model is to provide a device for removing the hinge hole bolt of the bottom pivot of a ship lock miter gate. This device adopts a jacking and pulling disassembly method, which can effectively overcome the inconvenience of disassembling the hinge hole bolt due to the narrow space, effectively improve the efficiency of disassembling the hinge hole bolt, and improve the convenience of disassembly. Moreover, this device is convenient to use and easy to store.

[0005] The connecting threaded hole is machined at the center of the hexagonal head of the hinge hole bolt to be disassembled.

[0006] The hinge hole bolt to be disassembled adopts an interference fit with the bottom pivot base of the miter gate.

[0007] A pull rod hole is machined on the bearing crossbeam for the pull rod to pass through, and the pull rod hole and the pull rod adopt a clearance fit.

[0008] The nut assembly comprises a lower nut and an upper nut installed on the pull rod through threaded cooperation, and the lower nut and the upper nut are respectively located at both ends of the bearing crossbeam.
