Description

Technical Field

[0001] This utility model belongs to the field of hydraulic metal structures, and specifically relates to a flip-claw locking device. Background Technology

[0002] In hydraulic metal structure flood control gates, the frequent opening and closing of working gates presents a significant challenge in terms of rapid and automatic locking, especially in ship lift working gates where high traffic volume necessitates multiple openings and closings daily. This frequent opening and closing of working gates is a common and critical operational requirement, particularly in hydraulic metal structure flood control gate systems. These gates not only control water flow and ensure reservoir safety but also, in certain applications such as ship lifts, guarantee the safe passage of vessels. However, existing gate locking mechanisms largely rely on manual operation or semi-automated equipment. This not only increases labor intensity and reduces work efficiency but also poses safety hazards due to operational delays in emergencies. Especially in ship lift working gates, the high traffic volume and frequent daily opening and closing demands higher requirements for rapid, accurate, and reliable locking. Traditional manual locking methods struggle to meet this high-frequency opening and closing demand, easily leading to misoperation or slow response times, thus affecting the ship lift's operational efficiency and safety.

[0003] Based on the above analysis, the technical problem to be solved by this utility model is that manual or semi-automatic locking methods have the risk of misoperation, which may lead to gate locking failure or untimely unlocking, affecting the safety and reliability of the system. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a flipping claw locking device, which has a simple structure, is easy to operate and use, reduces personnel involvement and increases safety during use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A flip-type chuck locking device includes a locking bracket with a locking seat. The locking seat is composed of a bushing, a chuck body, a shaft, a stop plate, and a baffle. The shaft sequentially fixes the stop plate, the baffle, the bushing, and the chuck body in a pre-drilled hole in the locking seat. The shaft cooperates with the bushing. The bushing is provided with a baffle, a stop plate, and a chuck body on its outside. The stop plate is located outside the baffle, and the chuck body is located in the middle of the bushing.

[0007] Preferably, the locking bracket is arranged above the gate slot and spans the orifice.

[0008] Preferably, the locking seat is bolted to the center of the middle crossbeam of the locking bracket, and the center of the locking seat is on the same straight line as the center of the gate slot.

[0009] Preferably, the locking bracket is a welded steel structure and serves as the main load-bearing structure. The locking bracket spans both sides of the gate slot and is supported on the columns on both sides of the gate slot.

[0010] Preferably, there are two baffles, which are located at both ends of the bushing. Each baffle has a stop plate at its outer end, and a retaining body is provided between the two baffles.

[0011] Preferably, the locking seat is welded together from a bushing, a clip, a shaft, a stop plate, and a baffle.

[0012] The present invention can achieve the following beneficial effects:

[0013] This invention employs a flip-type claw locking device. A locking beam is installed on the upper part of the locking platform, and a locking arm is located on the side of the locking beam near the gate. The locking arm is connected to the locking beam via a locking shaft, and a hanger is welded onto the gate body. When the locking arm is not in operation, its front end naturally tilts downwards. In operation, the front end of the locking arm is in contact with the hanger on the gate, and flips to engage with the hanger as the gate rises. The flexible flipping of the locking arm around the shaft enables automatic locking or unlocking during gate opening and closing, requiring no manual operation and well-suited to the frequent opening and closing conditions of working gates. To ensure locking reliability, a claw position detection device is included in the locking device. When the gate rises, the front end of the locking arm engages with the hanger on the gate and flips as the gate rises, ultimately engaging with the hanger to achieve automatic locking. When the gate descends, the locking arm naturally tilts downwards under gravity, separating from the hanger and achieving automatic unlocking. The entire process requires no manual intervention, greatly improving the efficiency and safety of gate opening and closing, and is especially suitable for work gate scenarios that require frequent opening and closing.

[0023] In hydraulic metal structure flood control gates, the frequent opening and closing of working gates has always posed a challenge in terms of rapid and automatic locking, especially in the working gates of ship lifts where high traffic volume necessitates multiple openings and closings daily. This invention employs a flip-type claw locking device. A locking beam is installed on the upper part of the locking platform, with a locking arm located on the side of the locking beam near the gate. The locking arm is connected to the locking beam via a locking shaft, and a hanger is welded to the gate body. When the locking arm is not in operation, its front end naturally tilts downwards; in operation, the front end of the locking arm engages with the hanger on the gate, flipping and locking with the hanger as the gate rises. By flexibly flipping the locking arm around its shaft, automatic locking or unlocking is achieved during gate opening and closing, eliminating the need for manual operation and effectively adapting to the frequent opening and closing conditions of working gates. To ensure locking reliability, a claw position detection device is incorporated into the locking device. The specific solution is as follows:

[0024] Preferred solutions include Figure 1-7 As shown, a flip-type chuck locking device comprises a locking bracket 1, a bushing 2, a chuck body 3, a shaft 4, a locking seat 5, a stop plate 6, and a baffle 7. The locking bracket 1 is a welded steel structure, serving as the main load-bearing structure. It spans both sides of the gate's rising slot and is supported by two side columns, transferring the weight of the locked gate to the concrete structure. The locking seat 5 is bolted to the center of the middle crossbeam of the locking bracket 1. The center of the locking seat 5 is collinear with the center of the gate slot. The locking seat 5 consists of a welded body, a bushing 2, a chuck body 3, a shaft 4, a stop plate 6, and a baffle 7. When the locking arm is not in operation, the front end of the chuck body 3 naturally tilts downwards. In operation, the front end of the locking arm is in contact with the gate's upper support, flipping and engaging with the support as the gate rises. By flexibly flipping the locking arm around its axis, the gate can be automatically locked or unlocked during opening and closing.

[0025] The operating principle of this device is as follows:

[0026] The main body of the locking bracket is a welded steel structure, with a locking seat welded in the middle of the crossbeam, and movable claws on the locking seat.

[0027] A locking beam is installed on the upper part of the locking platform, and a locking arm is located on the side of the locking beam near the gate. The locking arm is connected to the locking beam via a locking shaft, and a hanger is welded onto the gate body. When the locking arm is not in operation, its front end naturally tilts downward; when in operation, the front end of the locking arm is in contact with the hanger on the gate, and it flips and engages with the hanger as the gate rises. By flexibly flipping the locking arm around the shaft, the gate can be automatically locked or unlocked during opening and closing. No manual operation is required during use, which is well adapted to the operating conditions of frequent opening and closing of the working gate.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
