Detailed Description
Example 1
Referring to fig. 1 and 2, the emergency release device for the electric deck crane provided in this embodiment includes a ball valve 1, a winch brake quick connector 2, a manual pump 3, a safety valve 5, a quick connector 7 and an oil tank 10, wherein in a system power-off release state, the quick connector 7 is connected to the winch brake quick connector 2 connected to the winch brake, the quick connector 7 is connected to the ball valve 1, the winch brake is installed on the oil tank 10, the manual pump 3 is connected to an oil port of the oil tank 10, and the safety valve 5 is arranged on the winch brake.
The winch brake is also connected to the oil tank 10 via a throttle valve 12.
The winch brake is provided with a first pressure unloading valve 4 and a pressure gauge 11.
The manual pump 3 is provided with a second pressure unloading valve 8 and an air filter 6.
One side of the winch brake is provided with a plug 9 with an O-shaped ring.
When the power is lost and the brake is released, the brake is connected to a winch brake quick connector 2 through a quick connector 7, a ball valve 1 is opened, oil is absorbed from an oil tank 10 through a manual pump 3, the oil is pumped into the brake through the quick connector 7, a spring is pushed open, the brake is opened, goods are placed downwards, and hydraulic oil pumped into the brake returns to the oil tank 10 of the manual pump unit through a throttle valve 12 after the manual pump stops operating. The manual pump valve group unit is provided with an air filter 6 for filtering air, a pressure gauge 11 for observing the pressure of the system, a first pressure unloading valve 4 and a second pressure unloading valve 8 for controlling the internal pressure of the system, a safety valve 5 for emergency unloading in special conditions, a plug 9 with an O-shaped ring is an emergency port, and a quick connector 7 can be connected at the position.
The device is different from the hydraulic crane emergency release and lies in that the hydraulic crane has a motor, operates the manual pump 3 and pumps oil to the speed reducer brake, and the brake is opened when pressure reaches 6 ~ 13bar, and the goods falls, and the motor is rotatory, falls to 0 with the pressure that manual pump 3 established, and the brake is closed, so repeats, ensures emergent release steady safety.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
