The existing conventional hydraulic gate opening and closing device can be divided into a fixed winch type opening and closing device, a hydraulic pull rod type opening and closing device, a hand-operated opening and closing device, a screw type opening and closing device and the like. The winch type hoist, the hydraulic pull rod type hoist and the screw type hoist all need to use a motor as a power unit (called as an electric hoist for short), and are provided with a necessary power supply system, an electric control system, a communication system, a speed reducing mechanism, a braking device, a winch or a hydraulic system for controlling the opening and the closing of a gate; the hand-operated hoist is provided with a hand-operated device, a speed reducing mechanism, a braking device, a winch or a screw rod to control the opening and closing of the gate.
The hand hoist system is complex, manual operation is time-consuming and labor-consuming, and needs cooperation of multiple people, the hoist is slow, and the quick hoist requirement of gate under emergency condition is difficult to satisfy.

When the conventional hydraulic gate opening and closing device is submerged under the conditions of dam overflow and canal overflow caused by natural disasters, or is limited by external working conditions, the conventional hydraulic gate opening and closing device can only operate the hydraulic gate in a wading environment, or the conventional hydraulic gate opening and closing device has a functional failure (such as losing working power supply and emergency power supply failure), the conventional hydraulic gate opening and closing device can not realize normal opening of the gate, and safety accidents are easily caused.
Based on this, in the specific embodiment provided in the present disclosure, a gate opening and closing device is provided, and as shown in reference to fig. 1, the gate opening and closing device is used for being connected with an electric hoist for controlling opening and closing of a gate, and includes: a housing 1; an emergency start-stop system 2 comprising an oil tank 201, a hydraulic pump 202, a hydraulic motor 203, a fuel engine 204, and a clutch 205 located outside the housing 1, which are provided inside the housing 1;

The present disclosure describes an electric hoist as an example of a hoist, and when a hoist power supply or a motor fails and a gate needs to be lifted, the clutch 205 is closed, so that an output shaft of the hydraulic motor is in driving connection with an input shaft of the motor 3 of the hoist. The fuel engine 204 is used as basic power, the hydraulic pump 202 is driven to extract hydraulic oil in the oil tank 201 and boost the pressure, the pressurized hydraulic oil flows into the hydraulic motor 203 through the first oil port 2031, the output shaft 2033 of the hydraulic motor rotates, and the input shaft of the motor 3 of the winch hoist is driven to rotate, so that the lifting of a gate is realized. In the process of lifting the gate, the first oil port 2031 is an oil suction port, the second oil port 2032 is an oil outlet, and hydraulic oil pumped by the hydraulic pump 202 enters the hydraulic motor through the first oil port 2031 and flows back to the oil tank through the second oil port 2032.

At this time, a person can control the falling speed of the gate by adjusting the flow valve 207, that is, the rotation speed of the hydraulic motor 2, and thus the falling speed of the gate, by controlling the flow rate of the hydraulic oil flowing through the flow valve 207. Further, by closing the high pressure ball valve 206, the gate may be prevented from falling, for example, holding the gate in a raised position.
