Abstract

The invention discloses a wedge-shaped block self-locking top tight device for a ship lift. The top tight device comprises a frame. One side of the frame is fixedly provided with a drive oil cylinder; a piston rod of the drive oil cylinder is connected to one end of a wedge-shaped drive block; a vertical surface of the wedge-shaped drive block faces toward the frame and an inclined surface of the wedge-shaped drive block faces outward; two swing arm supporting seats are fixed on the frame at two sides of the wedge-shaped drive block; the swing arm supporting seats are hinged with two swing arms; the other ends of the swing arms are co-axially hinged with two sides of a wedge-shaped top tight block; a top tight surface of the wedge-shaped top tight block faces outward; an inclined surface of the wedge-shaped top tight block is contacted with the inclined surface of the wedge-shaped drive block; and a chamfered angle of the wedge-shaped drive block and the wedge-shaped top tight block is smaller than a frictional angle of a friction surface. The self-locking characteristic of the wedge-shaped block guarantees that a ship tank is in a reliable locking state under the effect of horizontal load; and the horizontal longitudinal load of the ship tank are transmitted to a track through the wedge-shaped block self-locking top tight device for the ship lift. The wedge-shaped block self-locking top tight device for the ship lift is convenient for operation, has high reliability, and can be widely applied in the field of water conservancy and hydroelectricity engineering ship lifts.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering ship lifts, in particular to a wedge block self-locking type ship lift jacking device. Background technique [0002] During the docking of the vertical ship lift with the upper and lower sluice heads, it will bear the hydraulic load along the water flow direction. In order to keep the horizontal position of the ship box under the hydraulic load, it is necessary to install a jacking device. Lock the cabin in the direction of the water flow. For ship lifts built on water conservancy and hydropower projects, there are fluctuations in the navigable water level in the upstream and downstream channels, so the working performance of the jacking device must adapt to the changing conditions of the water level in the channel. [0003] During the normal lifting process of the ship box, a certain gap must be maintained between the jacking device and the track to avoid the device fr...
