Abstract
Description
Technical Field
[0001] This application relates to the fields of mechanical transmission and hydraulic engineering, and in particular to a vertical slow-speed screw herringbone gate opener. Background Technology
[0002] In plains areas, rivers are widely distributed, with numerous small-scale sluice gates. These sluice gates effectively regulate water flow, ensuring irrigation and flood control needs in surrounding areas, and playing a crucial role in agricultural production and the rational allocation of regional water resources. In related technologies, for these small-scale sluice gates, when facing still water opening and closing, or when the operating head is relatively small, a vertical lift flat gate machine frame structure is often used. When small waterways require small vessel navigation, the frame needs to be built very high to accommodate vessel passage. Regarding the aforementioned technologies, the inventors believe that if the vertical lift flat gate machine frame structure is built very high, there are significant safety hazards for personnel during operation, and the towering frame will negatively impact the surrounding landscape. Furthermore, conventional hydraulic equipment is prone to failure when the gate opening and closing frequency is low, and its operation is also susceptible to flood levels, making stable and reliable operation impossible. Summary of the Invention
[0003] To improve the working stability of hydraulic equipment, this application provides a vertical slow-speed screw miter gate opener and a vertical miter gate.
[0004] The technical solution of the vertical slow-speed screw miter gate opener and the vertical miter gate provided in this application is as follows: In the first aspect, this application provides a vertical slow-speed screw miter gate opener / closer, which adopts the following technical solution: A vertical slow-speed screw herringbone gate opener includes a drive base, a rotating mechanism rotatably mounted on the drive base and driving the gate leaf body to rotate, and a drive mechanism driving the rotating mechanism to rotate. The rotating mechanism includes a drive shaft and a drive arm connected to the drive shaft and driving the herringbone gate to rotate. The drive base has a swing opening for the drive shaft to rotate. The drive mechanism includes a drive motor and a reduction gear connected to the output end of the drive motor. The bottom of the drive base is provided with a shaft base for the end of the drive shaft to be rotatably connected.
[0005] By adopting the above technical solution, the drive base provides support and installation foundation for the rotating mechanism and the drive mechanism. The drive shaft of the rotating mechanism can rotate flexibly in conjunction with the swing opening. The drive arm drives the miter gate to rotate. The reduction component of the drive mechanism reduces the output of the drive motor. The shaft base ensures stable rotation of the end of the drive shaft, realizing slow and stable drive of the miter gate. The structure is reliable and can adapt to the operating environment such as low opening and closing frequency and flood level, which helps to improve the working stability of hydraulic equipment.
[0006] Optionally, the reduction assembly includes at least two stages of speed reducers.
[0007] By adopting the above technical solution, the deceleration assembly uses at least two-stage reducers, which can achieve multi-stage deceleration and more accurately control the rotation speed of the rotating mechanism, thereby driving the door leaf body to rotate more smoothly.
[0008] Optionally, the reduction assembly includes a primary reducer connected to the output end of the drive motor for primary reduction and a secondary reducer connected to the output end of the primary reducer for secondary reduction; the output end of the secondary reducer is provided with a connecting short shaft for connection to the drive shaft, and the connecting short shaft and the output end of the secondary reducer are connected by a coupling.
[0009] By adopting the above technical solution, the first-stage reducer and the second-stage reducer reduce the output of the drive motor twice, which can accurately control the speed of the drive shaft and meet the slow-speed operation requirements of the vertical slow-speed screw herringbone gate opener; the connecting short shaft is used to connect the drive shaft, and the coupling makes the connecting short shaft and the output end of the second-stage reducer cooperate to compensate for the relative displacement between the two and ensure smooth power transmission.
[0010] Optionally, the drive shaft includes a vertically arranged shaft body and an extension connected to the shaft body and perpendicular to the shaft body; the extension has a mounting flange at one end away from the shaft body for mounting the drive arm.
[0011] By adopting the above technical solution, the drive shaft is provided with a rotating shaft body and an extension, and the drive arm is detachably installed on the extension via a mounting flange, which facilitates the installation and disassembly of the drive arm and improves the assembly and maintenance efficiency of the equipment. At the same time, the extension perpendicular to the rotating shaft body can more effectively transmit the rotation of the drive shaft to the drive arm, thereby driving the door leaf body to rotate.
[0012] Optionally, the lower end of the rotating shaft body has a coaxially arranged connecting column, and the shaft base is provided with an insertion groove along the axial direction of the rotating shaft body for the connecting column to be inserted into, and a rotary bearing for the connecting column to be rotated is provided in the insertion groove.
[0013] By adopting the above technical solution, the cooperation between the connecting column and the insertion slot can accurately connect the rotating shaft body and the shaft base. The setting of the rotary bearing can ensure that the connecting column can rotate flexibly in the shaft base, thereby ensuring the stable rotation of the drive shaft, and thus ensuring the stability and reliability of the vertical slow screw herringbone door opener driving the door leaf body to rotate.
[0014] Optionally, the drive base is provided with reinforcing ribs.
[0015] By adopting the above technical solution, the reinforcing ribs on the drive housing can enhance the structural strength of the drive housing, enabling it to better withstand the forces generated during the rotation of the drive shaft, and thus helping to extend the service life of the drive housing.
[0016] Secondly, this application provides a vertical herringbone door, which adopts the following technical solution: A vertical miter gate includes a gate head sidewall, at least one gate leaf body rotatably arranged on the gate head sidewall for closing a river channel, and the aforementioned vertical slow-speed screw miter gate hoist; the drive arm is provided with a drive column at its movable end for driving the gate leaf body to rotate, and the gate leaf body is provided with a sliding groove for the drive column to slide.
[0017] By adopting the above technical solution, the drive mechanism of the vertical slow screw miter gate opener drives the rotating mechanism to rotate. The drive arm of the rotating mechanism slides in the sliding groove of the gate leaf body through the drive column at the movable end, causing the gate leaf body to rotate around the gate head side wall, thereby realizing the closure and opening of the river channel.
[0018] Optionally, the number of gate leaf bodies is one, and the gate head sidewall is provided with a hydraulic locking mechanism for locking the movable end of the gate leaf body. The hydraulic locking mechanism includes a locking rod and a hydraulic drive component for driving the locking rod to move. The gate leaf body has a locking groove for locking the locking rod.
[0019] By adopting the above technical solution, a single gate leaf body, in conjunction with a hydraulic locking mechanism, can use a hydraulic drive component to drive the locking rod to move and insert into the locking groove, thereby achieving reliable locking of the movable end of the gate leaf body and ensuring the stability of the river closure.
[0020] Optionally, the number of gate leaf bodies is two, and the two gate leaf bodies are arranged opposite to each other on both sides of the gate head sidewall.
[0021] By adopting the above technical solution, the two gate leaf bodies arranged opposite each other on both sides of the gate head sidewall can better achieve the closure of the river channel. When the two gate leaf bodies are closed, they support each other to form a "three-hinged arch" structure, which enhances the sealing effect and stability without the need to add a hydraulic locking mechanism.
[0022] In summary, this application includes at least one of the following beneficial technical effects: A vertical slow-speed screw-driven miter gate opener / closer includes a drive base, a rotating mechanism, and a drive mechanism. The drive base provides support and a mounting foundation for the rotating and drive mechanisms. The drive shaft of the rotating mechanism can rotate flexibly in conjunction with the swing opening. The drive arm drives the miter gate to rotate. The reduction gear of the drive mechanism reduces the output of the drive motor. The shaft base ensures stable rotation at the end of the drive shaft, achieving slow and stable drive of the miter gate. The structure is reliable and adaptable to low opening / closing frequencies and flood levels, contributing to improved operational stability of hydraulic equipment. Multi-stage reducers can more effectively reduce the output speed of the drive motor, so that the rotation speed of the rotating mechanism driving the door leaf body to rotate is more in line with the slow speed requirement, which helps to improve the stability and safety of the opening and closing of the miter door; A vertical miter gate includes a gate head side wall, a gate leaf body, and the aforementioned vertical slow-speed drop arm miter gate opening and closing machine; the driving mechanism of the vertical slow-speed screw miter gate opening and closing machine drives the rotating mechanism to rotate, and the driving arm of the rotating mechanism slides in the sliding long groove of the gate leaf body through the driving column at the movable end, thereby driving the gate leaf body to rotate around the gate head side wall, thus realizing the closure and opening of the river channel.
