Description

A swing arm type flat gate locking mechanism driven by a hydraulic cylinder

technical field

The utility model relates to the field of water conservancy and hydropower engineering, and more specifically relates to a swing arm type plate gate locking mechanism driven by a hydraulic oil cylinder.

Background technique

Vertical ship lifts built on water conservancy and hydropower projects are generally equipped with flat-plate working gates at the upper and lower gates. Usually, the water level of the downstream channel is affected by the tail water of the power station and the flood discharge of the dam, and the water level has a large amplitude and high frequency conversion. In order to meet the normal docking between the ship lift and the lock head, it is necessary to frequently adjust the height of the lock head working door. In order to ensure the normal operation of the ship lift, it is necessary to set up a locking mechanism that can adapt to the changing conditions of the water level of the channel, provide support for the front plate working gate, and can quickly enter and exit the locked state.

Most of the existing working doors at the head of the gate adopt hydraulic pin-type locking devices. This kind of device has extremely high requirements on the positioning accuracy of the gate. The gate can only be locked at a certain fixed position in the height direction, and it is difficult to quickly enter and Get out of the locked state. It is also possible to use the function of the hoist mechanism itself to lock the working door of the gate head, such as: holding the hydraulic hoist to maintain pressure, fixing the brake of the winch, etc.; this method has high requirements on the performance of the hoist. Once the hoist functions If it fails, the gate will fall and cause serious accidents.

detailed description

The implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation of the present utility model, they are only examples, and the advantages of the present utility model will become clearer and easier to understand.

Referring to Figure 1: a swing arm type flat gate locking mechanism driven by hydraulic cylinders, the body 7 of the swing arm type flat gate locking mechanism driven by several hydraulic cylinders is arranged in sequence along the longitudinal direction, each of the hydraulic cylinders drives The swing arm type flat gate locking mechanism body 7 includes a drive cylinder 1, a swing arm 2, a lock shaft and a shaft sleeve 3, a support block 4, a lock support track 5, a stepped lock frame 6 and a drive cylinder hinge seat 7; the drive The oil cylinder 1 is installed under the swing arm 2, the tail of the driving oil cylinder 1 is hinged with the gate side post hinge seat 1.1 arranged on the gate side post 2.1, and an oil cylinder is arranged on the described driving oil cylinder 1 Piston rod 1.2, the piston rod 1.2 of the oil cylinder is hinged to the bottom of the swing arm 2, and the upper part of the swing arm 2 is connected to the ear plate 2.1 on the side post 2.1 of the gate through the locking shaft and bushing 3. 1 Hinged; the support block 4 is installed on the upper end of the gate side column 2.1, and the other side of the gate side column 2.1 is provided with a locking step lock frame 6, and the adjacent step The locking frames 6 are fixed by bolts, and the tails of the stepped locking frames 6 are embedded in the concrete 9 of the gate wall, and the locking support rails 5 are installed on the groove surface of the stepped locking frames 6 .

The pressure-bearing surface of the swing arm 2 is arc-shaped, and the arc-shaped pressure-bearing surface of the swing arm 2 is tangent to the upper surface of the locking support track 5 .

The swing arm 2 can rotate around the locking shaft and the bushing 3. After the swing arm 2 is pushed out by the drive cylinder 1, the arc-shaped pressure bearing surface of the swing arm 2 contacts the locking support track 5, and the gravity load of the gate passes through the swing arm 2. It is passed to the locking support track 5, and then passed to the concrete gate wall 9 by the subsequent staged locking frame 6.

The upper part of the swing arm 2 presses against the support block 4 and forms a geometrically invariant body. When the swing arm is supported and locked, its upper part is in contact with the support block 4 installed on the side column 2.1 of the door body. Under the action of the heavy load of the door, the swing arm 2 presses against the support block 4 to form a geometrically invariant body and complete the gate's movement. Lock support.

The utility model includes the following specific operation process: during the lifting and lowering of the gate to adjust the position of the door body, the swing arm 2 is retracted by the driving cylinder 1, and the driving cylinder 1 is locked. The position of the gate body is generally adjusted, and it is ready to enter the supporting and locked state. The swing arm 2 is pushed out by the drive cylinder 1 until the upper part of the swing arm 2 contacts the support block 4, and the drive cylinder 1 is locked to keep the swing arm 2 pushed out. At this time, the swing arm 2 There is a gap of about 20 mm between the arc-shaped pressure-bearing surface at the lower end and the rail surface of the locking support rail 5, and slowly lower the gate until the arc-shaped pressure-bearing surface of the swing arm 2 contacts the rail surface of the locking support rail 5, and the gate is completed. Locked, at this time, the drive cylinder 1 can release the locked state and release the pressure.

When the gate needs to readjust the position of the gate body, first slowly lift the gate by about 20mm, the arc-shaped pressure bearing surface of the swing arm 2 is separated from the rail surface of the locking support track 5, and the swing arm 2 is retracted by the drive cylinder 1, and the drive cylinder 1 is locked , the gate can only be lifted and operated to adjust the position of the gate body.

The parts not described in detail above are all prior art.
