[0021] Example

[0022] The locking device of the large gate in this example is Figure 1 to 5 As shown, it includes a geared motor 15, a gate locking beam 4, a rail 3, a gate inspection platform 1, a gate 18, and a limit block 18. The gate locking beam 4 is composed of a driven wheel 12, an adjusting nut 8, a spring 9, an adjusting bolt 7, a positioning sleeve 6, a key shaft 14, a bearing 13, a driving wheel 11, a supporting plate 10 and a wheel frame 5. The rail 3 is seated on the base 16, and the two ends of the rail are provided with limit blocks 17.

[0023] The rail 3 is installed on the gate overhaul platform 1 to support the locking beam device; the limit blocks 18 are fixed at both ends of the rail 3 to limit the running distance of the gate locking beam 4; the gate locking beam 4 is installed on the rail 3 for use In the lock gate 18; the decelerating motor 15 is installed on the gate lock beam 4 to drive the gate lock beam 4 to walk.

Abstract

The invention discloses a locking method and device for a large gate. Walking devices are arranged at the two ends of a gate locking beam, meanwhile, rails are arranged on the two sides of a gate groove of an overhauling platform of the gate, and the gate locking beam moves on the rails in a reciprocating manner through the walking devices; when the gate locking beam is located on the outer side of the gate groove, the gate is not limited by the gate locking beam and can slide along the gate groove up and down. When the gate and the gate groove need to be overhauled, the gate is lifted firstly, then the gate locking beam is operated to the gate groove through the walking devices, and finally the two ends of the gate are erected on the gate locking beam. By means of the locking method and device for the large gate, the operation difficulty caused by the large weight of large or ultra-large gate locking beams in a hydropower station can be solved, automated control over operation and remote operation can be achieved, operation safety and operation efficiency are improved beneficially, operation cost is lowered, and the locking method and device have good economic benefits and can be popularized in the field of hydropower station design.

Description

technical field [0001] The invention relates to a locking method and device for a large gate, belonging to the technical field of gate locking in water conservancy and hydropower projects. Background technique [0002] The gate locking device is a gate bearing mechanism widely used in water conservancy and hydropower projects. Usually, the gate locking device is placed outside the gate groove on the gate maintenance platform. When the gate is installed and maintained, the operator pushes the gate locking beam to the hole At the mouth, it is used to fix the gate. For large and ultra-large gates, the dead weight of the gate locking beam can reach several tons. No matter whether it is supported by sliders or wheels, it is still difficult to operate by manual push. Moreover, due to the constraints of the hydraulic structure, the operating space of the gate locking beam is generally relatively narrow. , manual operation is difficult, prone to accidents, resulting in casualties. ...
