Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Figure 3 to Figure 11 Shown is the embodiment of the guide device for lifting the miter door of the ship lock according to the present invention, the guide device includes a base 5 and a guide shaft 6, the base 5 is connected to the gate wall, and is located between the top pivot 2 of the miter gate and the gate wall At the joint, the guide shaft 6 passes through the top pivot 2 and is firmly connected with the base 5. In this structure, before lifting the miter gate, the connection end between the top pivot 2 and the gate wall is first disassembled, and then the top pivot 2 Install the base 5 at the original connection with the gate wall, then pass the guide shaft 6 through the original connection point of the top pivot 2 along the vertical direction of the door leaf 1, and finally fasten the guide shaft 6 passing through the...

Abstract

The invention discloses a guide device for jacking a miter gate of a lock. The guide device comprises a base and a guide shaft; the base is connected to a lock wall and located at the joint of a top pintle of the miter gate and the lock wall; the guide shaft penetrates through the top pintle and is fastened to the base; while the miter gate is jacked, the top pintle and a gate flap move vertically along the guide shaft. The guide device has the advantages of simple structure, convenience for operation and effective prevention of horizontal displacement of the miter gate.

Description

technical field [0001] The invention mainly relates to the technical field of overhauling the miter gate of a ship lock, in particular to a guide device for lifting the miter gate of a ship lock. Background technique [0002] In large-scale water conservancy and hydropower projects, the ship lock is equipped with a miter gate structure, such as figure 1 As shown, the miter door comprises parts such as door leaf 1, top pivot 2, bottom pivot, and top pivot 2 and bottom pivot are subpackaged on the top and the bottom of the door shaft column of door leaf 1, have the function of hinge shaft. The top hinge 2 plays a stabilizing role, while the weight of the door leaf 1 is borne by the bottom hinge, which is the most important force-bearing part of the miter door, so the bottom hinge is designed as a movable structure to facilitate the maintenance of the bottom hinge. [0003] During the maintenance and replacement of the bottom hinge of the miter door, the door leaf 1 needs to b...
