Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering equipment technology, and in particular to an emergency operating system for a hoist gate opener. Background Technology

[0002] As a commonly used lifting device in water conservancy projects such as gates, locks, and hydropower stations, the reliability and emergency operation capability of winches are directly related to the safety of project operation and the realization of key functions such as flood control and navigation. Under normal operating conditions, winches are usually driven by electric motors, and the opening and closing of the gate is achieved through a reduction gear, drum, and wire rope.

[0003] In the existing technology, in order to meet the emergency operation needs of hoist gate openers in the event of power outages or failures of key components such as motors and reducers, a hand-cranked operating mechanism is generally used as a backup drive method. This method usually involves setting a hand-cranked device on the high-speed shaft or intermediate shaft of the reducer, and using human power to crank the handle to drive the drum to rotate through the original transmission chain, thereby realizing the emergency lifting or lowering of the gate. However, this traditional hand-cranked operating mechanism is limited by the human hand cranking torque, and the operating speed is extremely slow. When the capacity or head of the hoist gate opener is large, it is difficult to meet the needs of the project.

[0004] CN102733360B discloses an emergency operation device and gate system for a winch gate opener, including components such as an oil tank, a hydraulic pump-type hydraulic motor, a speed control valve, and a clutch. The speed control valve controls the rotational speed of the hydraulic pump-type hydraulic motor to control the gate's lowering and raising at a specified speed. The device is also equipped with a portable fuel-hydraulic pump station, which connects to the hydraulic pump-type hydraulic motor via a quick-connect coupling to provide an emergency power source. However, its emergency operating system is complex, inconvenient to install and maintain, and its operation procedures in emergency situations are cumbersome, hindering rapid response. Existing technologies lack an effective coordination mechanism between the braking system and the emergency operating system, and most lack effective status monitoring and safety interlock functions, failing to monitor the clutch's disengagement or engagement status in real time, which can easily lead to misoperation and affect system safety. Summary of the Invention

[0010] As a preferred embodiment of the present invention, a set of detection units includes a proximity switch b and a proximity switch a, which are respectively disposed directly below gear a and gear b, for detecting the position of the sleeve, thereby determining whether the manual clutch assembly is in a disengaged or engaged state.

[0011] As a preferred embodiment of the present invention, the transmission structure includes a T-shaped box installed in the upper mounting space of the support body, and the upper end of the T-shaped box is connected to the output end of the emergency operator via a coupling.

Therefore, they should not be construed as limitations on this invention.

[0021] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0022] An emergency operating system for a hoist gate opener includes a main mounting frame, which is a support body 3. The support body 3 is set on the side of any end of the motor 5 that needs to be driven in an emergency, and can be installed in different ways. The support body 3 is functionally partitioned in structure, with multiple independent installation spaces arranged from top to bottom to orderly support the various functional modules of the system.

[0023] An emergency operator 4 is installed at the top of the main body 3. The emergency operator 4 is the core power source and integrates a hydraulic drive component. This hydraulic drive component transmits torque outward through the output shaft 43 that passes through the housing of the emergency operator 4. To facilitate quick connection with external hydraulic lines, the housing of the emergency operator 4 is provided with connecting pipes a41 and b42. Each of these connecting pipes integrates at least two quick connectors for easy on-site installation and disassembly. By connecting different quick connectors, the direction of the output shaft 43 can be changed. The emergency operator 4 obtains power through an external hydraulic pipeline system. Specifically, it is connected to an independent oil tank 1 through a hydraulic pipeline. The oil tank 1 is stably supported by an oil tank bracket 2. At the same time, the oil tank 1 is also connected to a power unit 6 through another hydraulic pipeline. The power unit 6 typically includes a diesel engine, a hydraulic pump, a control valve group, and a controller. It is located in the passage between the two hoists to provide pressurized oil to the hydraulic circuit and perform intelligent control.

[0024] The rotational motion output by the emergency operator 4 is transmitted to the lower actuator through a transmission structure. In this embodiment, the transmission structure includes a T-shaped box 7 installed in the upper mounting space of the bracket body 3. The T-shaped box 7 is essentially a reduction or steering gearbox, and its input end is reliably connected to the output shaft 43 of the emergency operator 4 through a coupling 8.

[0025] Within the central installation space of the bracket body 3, a crucial manual clutch assembly 9 is installed. This assembly functions to switch between emergency mode and normal mode. Its outer end, namely the motor shaft docking end 91, is designed to directly engage with the rear output shaft end of the motor 5 or the input shaft end of the reducer. Its inner end, namely the T-shaped box docking end 92, is connected to the output shaft of the aforementioned T-shaped box 7. The specific structure of the manual clutch assembly 9 includes the T-shaped box docking end 92, which is fixedly connected to the output shaft of the T-shaped box, and has a gear a93 fixed at its end; and the motor shaft docking end 91, which is fixedly connected to the motor shaft, and has a gear b94 fixed at its end. Gear a93 and gear b94 are arranged coaxially, but there is an axial clearance between them. Under normal conditions, the two are separated and do not transmit torque. To enable the engagement and disengagement of power, a linkage component, namely a sleeve 97, is slidably fitted around gears a93 and b94. The inner hole of the sleeve 97 is machined with internal teeth that perfectly match the outer edge tooth grooves of gears a93 and b94. The middle part of the sleeve 97 is provided with an inwardly recessed groove 98, the thickness of which is greater than the sum of the thicknesses of gears a93 and b94. This allows the sleeve 97 to selectively engage only one gear during axial sliding, i.e., in the disengaged state, or to engage both gears simultaneously, i.e. in the linked state, thereby rigidly connecting the two together.

[0026] Please refer to Figure 4 and 5 The sliding of the sleeve 97 is operated by a set of manually driven components, which includes two push rings 96 that are engaged with the sides of the groove 98. The two push rings 96 are connected by a bracket a95. A lever 912 is fixed at the upper middle part of the bracket a95. The lever 912 is hinged to a bracket b99 fixed on the bracket body 3 by a pivot. The operator rotates the lever 912 around the hinge point, thereby driving the sleeve 97 to slide precisely along the axial direction through the bracket a95 and the push rings 96.

[0027] Please refer to Figure 4 and 5 In order to accurately provide feedback on the clutch status to the control system, a set of detection units is set below the manual clutch assembly 9. The detection unit includes two non-contact sensors, such as proximity switch a10 and proximity switch b11, which are precisely aligned with specific positions below gear a93 and gear b94, respectively.

[0028] The detection principle is as follows: When the sleeve 97 slides to fully cover gear a93, that is, when the emergency power is ready but the motor shaft is not connected, the proximity switch a10 is triggered by the metal body of the sleeve 97. When the sleeve 97 slides to simultaneously cover gears a93 and b94, that is, when the emergency power is connected to the motor shaft, both proximity switches are triggered. Proximity switches a10 and b11 transmit the detected position signals to the controller in the power unit 6 in real time through wires. The controller judges the real-time status of the manual clutch component 9 according to preset logic, such as double triggering representing linkage, and only A triggering representing standby, and decides whether to allow the emergency operator 4 to be started and how to control other related actions, thus realizing status monitoring and system interlocking and improving operational safety.

[0029] At the connection between the front shaft of motor 5 and the output shaft of reducer, a braking assembly is provided. The assembly includes a hydraulically driven cylinder 12. The output shaft of cylinder 12 is hinged to a connecting rod a13. The connecting rod a13 amplifies and converts the linear thrust of cylinder 12 into a clamping or releasing action on the brake element through a compound connecting rod mechanism consisting of connecting rod b14, connecting rod c15 and connecting rod d17.

[0030] Specifically, brake seats 16 are fixed to the inner sides of the two connecting rods b14, and brake blocks 18 are mounted on the brake seats 16. The brake blocks 18 are directly opposite the brake disc or brake arm that needs to be controlled. The hydraulic cylinder 12 is connected to the working brake port of the power unit 6 through a high-pressure oil pipe. When emergency operation is required, after confirming that the clutch is in the correct state, the controller can instruct the power unit 6 to supply oil to the hydraulic cylinder 12, pushing the connecting rod mechanism, thereby actively releasing the original working brake.

[0031] Furthermore, the main body 3 of the support can adopt a modular design, which is composed of a detachable and connectable upper support 31, middle support 32 and lower support 33, which facilitates transportation and on-site adaptability adjustment. The bottom end of the lower support 33 can be equipped with a welding seat 34, which is firmly fixed to the hoist platform or foundation by welding to ensure the stability of the entire emergency system during operation.

[0032] When the main power supply fails and an emergency gate opening / closing is required, the operator first goes to the site and manually operates lever 910 to push sleeve 97 to the position where gears a93 and b94 are simultaneously connected, i.e., in the interlocked state. At this time, proximity switches a10 and b11 send the interlocked signal to the controller. After receiving the clutch interlock signal, the controller automatically or manually allows hydraulic oil to flow to the emergency operator 4, driving it to rotate. The power is transmitted through coupling 8, T-shaped box 7, and the interlocked manual clutch assembly 9, finally reaching the shaft end of motor 5, thereby driving the entire reducer and drum mechanism to realize the emergency lifting or lowering of the gate. The whole process is powerful and the speed is controllable, completely solving the problems of low torque and slow speed in the traditional hand-cranked method.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
