Technical Field
[0001] This utility model relates to a rotary gate locking rod, belonging to the field of water conservancy engineering technology. Background Technology
[0002] In the water industry, gates are crucial devices for controlling water flow and levels, widely used in key facilities such as reservoirs, dams, drainage systems, and sewage treatment plants. The gate locking lever, as one of its core components, plays a vital role in ensuring the gate closes securely and controlling water flow.
[0003] Currently, traditional gate locking rods often have relatively simple locking structures and pose safety hazards, such as... Figure 6 The gate locking rod shown includes a gate locking rod 02 and a gate 01. The gate 01 is provided with a limiting protrusion 011. In use, the gate 01 is lifted by a lifting device, and then the gate locking rod 02 is placed into the edge groove. The limiting protrusion 011 rests on the gate locking rod 02, and the gate 01 is supported by the limiting protrusion 011 and the gate locking rod 02. However, this method has some problems. First, the operation of this traditional gate locking rod is complicated and labor-intensive. This process may take a long time and requires a high level of physical strength from the operator, which can easily lead to fatigue and accidents. It requires the operator to crawl into the gate opening and closing area to move or release the gate locking rod 02. Second, there is a risk of the operator bumping their head and falling when crawling into the gate opening and closing area. In addition, there is also a risk of the gate locking rod 02 falling into the water during operation. Moreover, due to human factors, the manually moved gate locking rod 02 may be mispositioned during installation, resulting in poor locking effect and safety hazards.
[0004] Therefore, it is necessary to design a new type of rotary gate locking rod that can prevent operators from crawling into the gate opening and closing area to operate, improve the safety and operating efficiency of the equipment, and at the same time avoid the risk of the gate locking rod falling off, so as to meet the requirements of safety and efficiency in the opening and closing of gates in water conservancy projects. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a rotary gate locking rod that is easy to operate and highly secure.
[0006] To achieve the above objectives, this utility model provides a rotary gate locking lever, comprising a hand crank and a gate locking part; the gate locking part includes a gate locking lever, a central rotating shaft, and fixing parts disposed on both sides of the central shaft; the fixing parts include a wall fixing plate, a housing mounted on the wall fixing plate, and a transmission structure disposed within the housing; the central rotating shaft is connected to the transmission structure of the fixing parts on both sides; the gate locking lever is mounted on an extension arm of the central rotating shaft; the transmission structure includes a first sprocket and a second sprocket, which are coupled by a transmission chain; the first sprocket is connected to the central shaft; a transmission force-bearing shaft is disposed on the second sprocket; the hand crank is inserted into the transmission force-bearing shaft.
[0007] The wall fixing plate is provided with a guide plate that is perpendicularly connected to it, and the guide plate is provided with a rocker guide ring and a shaft fixing ring.
[0008] The top end of the transmission shaft is provided with a limit bolt.
[0009] The hand crank is provided with a limiting groove at its insertion end; when the hand crank is inserted into the transmission force shaft, the limiting bolt is placed in the limiting groove.
[0010] The hand crank has a stepped groove inside its insertion end, and the corresponding transmission shaft has a stepped base. When the hand crank is inserted into the transmission shaft, the stepped base is inserted into the stepped groove.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] like Figure 1-6As shown, a rotary gate locking lever of this utility model includes a hand crank 1 and a gate locking part 2; the gate locking part 2 includes a gate locking lever 3, a central rotating shaft 4, and fixing parts 5 disposed on both sides of the central shaft; the fixing part 5 includes a wall fixing plate 51, a housing 52 installed on the wall fixing plate 51, and a transmission structure 53 disposed in the housing 52; the central rotating shaft 4 is connected to the transmission structure 53 of the fixing parts 5 on both sides; the gate locking lever 3 is installed on the extension arm 42 of the central rotating shaft 4; the transmission structure 53 includes a first sprocket 531 and a second sprocket 532, the first sprocket 531 and the second sprocket 532 are engaged by a transmission chain 533; the first sprocket 531 is connected to the central shaft; a transmission force-bearing shaft 54 is provided on the second sprocket 532; the hand crank 1 is inserted into the transmission force-bearing shaft 54. By combining the hand crank 1 with the transmission structure 53, the operator can easily manually control the locking and unlocking process of the gate locking lever 3 by rotating the hand crank 1. Meanwhile, the transmission structure 53 uses a combination of a sprocket and a transmission chain 533, making the operation smoother.
[0023] The wall fixing plate 51 is provided with a guide plate 6 perpendicularly connected to it. The guide plate 6 is equipped with a rocker arm guide ring 61 and a shaft fixing ring 62. The rocker arm guide ring 61 assists the hand crank 1 in accurately engaging with the transmission force shaft 54 during the insertion operation. Furthermore, it ensures that the hand crank 1 always stays on the correct trajectory, preventing deviation or jamming due to uneven force or external interference during use, further ensuring smooth movement of the hand crank 1, thereby improving operational accuracy and stability. Moreover, the rocker arm guide ring 61 and shaft fixing ring 62 on the guide plate 6 effectively reduce the friction between the hand crank 1, the transmission force shaft 54, and the fixed structure, reducing wear caused by frequent operation, extending service life, and lowering the frequency of maintenance and replacement.
[0024] The top end of the transmission shaft 54 is provided with a limiting bolt 541, which is used to ensure that the rotational torque is reliably transmitted between the sprocket and the shaft without slippage or relative rotation. At the same time, it can also prevent the transmission shaft 54 from axially moving or misaligning during operation, ensuring that it always stays in the correct position. This helps to maintain the stability of the entire transmission system and avoids mechanical failures or performance degradation caused by shaft displacement.
[0025] The hand crank 1 has a limiting groove 11 at its insertion end. When the hand crank 1 is inserted into the transmission shaft 54, the limiting bolt 541 is placed in the limiting groove 11 to ensure that the hand crank 1 can be accurately positioned when inserted into the transmission shaft 54. After the limiting bolt 541 is embedded in the limiting groove 11, it can prevent the hand crank 1 from shifting or rotating during operation, thereby ensuring the stability and accuracy of operation.
[0026] The hand crank 1 has a stepped groove 12 inside its insertion end, and the corresponding transmission shaft 54 has a stepped base 542. When the hand crank 1 is inserted into the transmission shaft 54, the stepped base 542 is inserted into the stepped groove 12, which makes the insertion of the hand crank 1 and the transmission shaft 54 more precise. Moreover, the mating structure of the stepped groove 12 and the stepped base 542 ensures a tighter and more uniform contact surface between the hand crank 1 and the transmission shaft 54, and also improves the torque transmission efficiency.
[0027] The gate locking rod 3 is a trapezoidal block structure with a bottom surface wider than its top surface. This design allows for a larger contact area when the gate locking rod 3 contacts the platform and the gate. Specifically, the wider bottom provides better support, ensuring greater stability and security of the locking rod in the locked state. Furthermore, the larger bottom width of the trapezoidal structure effectively disperses the force acting on the locking rod, preventing excessive localized stress and reducing the risk of material damage. Compared to traditional rectangular or circular structures, the trapezoidal block structure provides better force distribution, enhancing the load-bearing capacity of the locking rod and adapting to higher pressure and load conditions.
[0028] The inner side of the extension arms 42 on both sides of the central rotating shaft 4 is provided with mounting shafts 41. The gate locking rod 3 is mounted on the extension arms 42 of the central rotating shaft 4 through the mounting shafts 41. When the central rotating shaft 4 rotates, the gate locking rod 3 can swing freely, which makes the movement of the gate locking rod 3 more flexible and avoids jamming or movement restriction that may occur when the locking rod is fixed. This ensures that the locking rod can interact smoothly with other components under different operating conditions, thereby improving operating efficiency.
[0029] The hand crank 1 has an anti-slip structure 13 at its handheld end to improve operational safety and increase hand comfort, preventing hand fatigue or discomfort caused by slippage during prolonged use. By optimizing the grip, operators can perform operations continuously for extended periods without discomfort, thereby improving work efficiency and user experience.
[0030] In use, the hand crank 1 and the transmission force shaft 54 are engaged by the auxiliary guide ring 61. At this time, the limiting bolt 541 is located in the limiting groove 11. By rotating the hand crank 1, the gate locking rod 3 is in a suspended, non-lifted state. Then, the gate 01 is lifted by the lifting device. Subsequently, the hand crank 1 is rotated in the opposite direction to place the gate locking rod 3 on the platform on both sides of the wall. At this time, the gate locking rod 3 is in a lifted state, with the larger bottom surface in contact with the platform. Then, the gate 01 is slowly lowered so that the limiting protrusion 011 of the gate 01 rests on the gate locking rod 3, thus completing the locking operation of the gate 01.
[0031] By adopting the above technical solution, the rotary gate locking rod 3 of this utility model, through the cooperation of the hand crank 1 and the transmission structure 53, allows the operator to easily manually control the locking and unlocking process of the gate locking rod 3 by rotating the hand crank 1. Simultaneously, the transmission structure 53 uses a combination of a sprocket and a transmission chain 533, making the operation smoother and avoiding the instability and cumbersome operation of traditional manual locking methods. Furthermore, the gate locking rod 3 adopts a trapezoidal block structure with a base wider than the top surface. This design improves the stability of its contact with the gate, enhances the locking effect, and more firmly fixes the gate, ensuring the safety of the gate during operation. In addition, the insertion structure of the hand crank 1 and the transmission force shaft 54, combined with the design of the limiting groove 11 and the limiting bolt 541, allows the hand crank 1 to be easily disassembled and installed. Operators can quickly disassemble components during maintenance or replacement, reducing maintenance time.
[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
