Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides a kind of rational in infrastructure, is adapted to a large amount of heavy-duty machinery operation environments, nonserviceable do not influence down normal operation windproof fender guard.
The technical scheme that realizes the foregoing invention purpose is: a kind of windproof fender guard; comprise driving handle, transmission device, braking iron wedge, actuator and frame plate; driving handle connects transmission device and actuator; the other end of transmission device connects braking iron wedge; transmission device is located between two frame plates, is provided with the steady arm of the improper whereabouts of connecting rod mechanism that stops the lifting state in described frame plate.
The setting of steady arm is in service at lift heavy for preventing hoisting crane, and the actuator motor stops hoisting crane in service and hard brake stop because of the unexpected whereabouts that happen suddenly outage or machine halt trouble cause braking the iron wedge in the wind-proof device, causes great or serious accident hidden danger.
Described steady arm can be: the bottom at described frame plate is provided with fixed platform, fixed platform is provided with actuating device, actuating device is provided with the pressure pin with the equidirectional extension of described actuator push rod, actuating device drives pressure pin and reaches raise-position and fall the position after rise, the upper end of pressure pin is provided with pallet, when pressure pin reached raise-position, pallet was held actuating arm.Pressure pin can effectively stop the improper down maneuver of connecting rod mechanism, the generation of stopping said circumstances.The on-off signal of pressure pin driver train can be taken from the control circuit signal of device, fall in control and the device braking iron wedge coordination operation and stop the synchronous protection function of the liter of realizing pressure pin.
Described steady arm can also be: the top at described frame plate is provided with fixed platform, fixed platform is provided with actuating device, actuating device is provided with the depression bar with the equidirectional extension of described actuator push rod, actuating device driving depression bar reaches and presses down position and normal position, depression bar ends transmission arm motion in the transmission device pressing down steric hindrance, falls thereby stop transmission device to drive the iron wedge.
In the utility model, the mal that pressure pin can be held actuating arm descends, and prevents the generation of said circumstances.The on-off signal of the driving switch of pressure pin can be taken from the large scale hoisting machinery run signal, realizes that driving switch falls control and large scale hoisting machinery in operation with stop synchronously to the liter of pressure pin.
As further improvement of the utility model, between described crank and braking iron wedge, be provided with setting device, described setting device is: be provided with the perforation screw on the fork arm of the bottom of described crank, the rear portion of braking iron wedge also is provided with corresponding hole, hole on screw rod connecting crank and the braking iron wedge, on the screw rod between braking iron wedge and the crank, be provided with spring, be used to adjust height and degree of dip after braking iron wedge is mentioned.
