Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a hook-type arc gate locking device. Background Art

[0002] In water conservancy and hydropower projects, radial gates are one of the most widely used gate types. They feature a circular retaining surface that can rotate about a horizontal hinge axis at the radius of the arc. This surface conforms closely to the streamlines of free outflow below the gate, and the flat sides of the gate piers do not interfere with the flow. Therefore, radial gates offer excellent hydraulic conditions for flood discharge. They are often used as working gates in flood discharge structures, capable of partial opening, and are typically operated by a hydraulic hoist. When the gate opens to discharge floodwater, the hydraulic hoist cylinder retracts to provide the opening force. Therefore, radial gates generally do not have locking devices. However, when the gate needs to discharge floodwater for an extended period, there is a risk of the hydraulic hoist cylinder being subjected to long-term loads. As owners demand increased reliability and safety from structural equipment, radial gates require safe and reliable locking devices to meet the demand for long-term gate opening, improve the reliability of gate opening conditions, and prevent the hydraulic hoist cylinder from being subjected to long-term loads.

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the present invention.

[0027] like Figures 1-8 The utility model describes a hook-type radial gate locking device, comprising two groups of gate locking units symmetrically arranged along the center line of the gate slot opening of the radial gate leaf 5. The gate locking unit comprises an anchor 1, a locking beam 2, a hook 3, and a locking lug 4. The anchor 1 and the locking beam 2 are buried in the concrete at the top of the gate slot on both sides of the radial gate leaf 5. The bottom of the locking beam 2 is connected to the anchor bar 1-1 of the anchor 1 through a fastener. The hook 3 is hinged to the overhanging section of the locking beam 2. The locking lug 4 is fixedly arranged on the panel of the radial gate leaf 5. The hook 3 constrains the hanging shaft 4-2 of the locking lug 4 to limit the rotation of the radial gate leaf 5 around the support hinge to achieve locking.

[0028] The two sets of gate locking units are arranged symmetrically. When the radial gate leaf 5 needs to be locked, the staff pushes the handle 3-2 of the hook 3 downstream to make the hook 3 leave the free state position, the hydraulic hoist 6 opens the door to a position slightly higher than the locking position of the radial gate leaf 5, the staff restores the hook 3 to the free state position, the hydraulic hoist 6 drops the door until the hanging shaft 4-2 of the locking lug 4 is suspended in the hook 3, and the radial gate leaf 5 is locked. When the radial gate leaf 5 needs to be unlocked, the hydraulic hoist 6 lifts the door to a height where the hook 3 can rotate and disengage, the staff pushes the handle 3-2 downstream to rotate and disengage the hook 3, the radial gate leaf 5 drops the door, and the staff releases the handle 3-2 to complete the unlocking.

[0029] The anchor 1 includes an anchor bar 1-1, an anchor plate 1-2, a nut 1-3, and a washer 1-4. The anchor plate 1-2 is used to position the anchor bar 1-1. The bottom of the anchor bar 1-1 is generally bent to enhance the anchoring force. The top of the anchor bar 1-1 is threaded and fixed with a nut 1-3 and a washer 1-4 to lock the beam 2.

[0030] A pin 2-2, an end stopper 2-3, a bearing 2-4, and a spacer ring 2-5 are provided on the locking beam 2. Screw holes are provided on the bottom plate of the locking beam 2 to connect to the anchor bar 1-1 of the anchor 1. The connection between the locking beam 2 and the anchor bar 1-1 is buried in concrete. Two shaft hole support plates are provided on the extended section of the locking beam 2, symmetrically arranged along the lifting point. The pin 2-2 is assembled in the shaft hole of the shaft hole support plate and is limited in position by the end stopper 2-3. The bearing 2-4 and the spacer ring 2-5 are assembled on the pin 2-2. The bearing 2-4 is generally a self-lubricating sleeve. The spacer ring 2-5 is used to separate the bearing 2-4 from the shaft hole support plate of the locking beam 2 to prevent axial movement of the hook 3. The hook 3 is hinged to the extended section of the locking beam 2 via the pin 2-2 and the bearing 2-4.

[0031] The extended section of the locking beam 2 is hinged to the pin 2-2, and the pin 2-2 is hinged to the bearing 2-4.

[0032] The hook 3 includes a hook plate 3-1, a handle 3-2, and a counterweight 3-3. The handle 3-2 is welded to the hook plate 3-1 to facilitate locking and unlocking the gate 5. The counterweight 3-3 is fixed to the top of the handle 3-2 to balance the weight of the hook plate 3-1, reducing the torque required to rotate the hook 3 and saving effort when pushing the handle 3-2 of the hook 3. The handle 3-2 is generally welded from a steel pipe. The counterweight 3-3 is generally a cylindrical steel cake with a hole in the middle that is installed on the top of the handle 3-2 and is generally welded.

[0033] An axial hole is opened on the hook plate 3 - 1 , and the bearing 2 - 4 passes through the axial hole on the hook plate 3 - 1 and is hinged to the pin shaft 2 - 2 on the locking beam 2 .

[0034] The locking lifting ear 4 includes a lifting ear structure 4-1, a lifting shaft 4-2, and an axis end baffle 4-3. The lifting ear structure 4-1 is a double lifting ear plate and is arranged symmetrically along the lifting point. The lifting shaft 4-2 is assembled with the ear hole of the lifting ear structure 4-1, and is limited by the axis end baffle 4-3. A pad is provided at the bottom of the lifting ear structure 4-1 to connect it into a whole and fix it on the panel of the radial gate leaf 5.

[0035] The hook plate 3-1 of the hook 3 is hung on the hanging shaft 4-2 of the locking lifting ear 4, which constrains the hanging shaft 4-2 to limit the rotation of the arc gate leaf 5 around the support hinge, thereby achieving locking.

[0036] The locking lug 4 can be fixed at any position in the arc direction of the radial gate leaf 5 to meet the need of locking any gate at any opening.

[0037] The locking lug 4 is fixed to a suitable position in the arc direction of the panel of the radial gate leaf 5 according to the locking opening requirement of the radial gate leaf 5.
