YFX electric hydraulic windproof iron wedge brake is mainly used as a gantry crane, loading and unloading bridge, and gate seat for outdoor use in ports, docks, railways, and other areas
Windproof devices for rail mounted cranes such as cranes in working conditions, which can also work together with other devices for the safety of cranes in non working conditions
Wind braking measures. When the crane encounters strong winds during operation, it can be safely braked.
2.1 Environmental temperature: -25 ° C~+50 ° C (please refer to the user manual of the thruster).
2.2 There should be no flammable, explosive, or corrosive gases in the surrounding working environment, and the relative humidity of the air should not exceed 90%.
2.3 Generally used for three-phase AC380V, 50Hz (see thruster nameplate).
2.3 The altitude of the location of use shall comply with the GB/T755-2000 standard.
2.4 Technical parameters: Wind resistance capacity of a single windproof iron wedge brake (converted into horizontal force) F:
F=fxN wheel (N wheel is wheel pressure, f is friction coefficient=0.46)
The FX series windproof iron wedge brake consists of two main parts: a brake frame and a matched Ed electric hydraulic thruster. When the thruster is on
Electricity, its push rod quickly rises and lifts the iron wedge through a lever and transmission mechanism to ensure normal operation of the crane; When the thruster is powered off, the thruster
The push rod is subjected to spring force and the iron wedge is placed on the steel rail through a lever. Wedge the wheels to ensure safety during a sudden storm
Protective effect. (Note: When the wheel presses against the iron wedge, the iron wedge cannot be lifted. At this time, the crane should be started in the opposite direction, and the iron wedge should be used for lifting.)
After lifting, the crane can resume normal operation
4.1 Installation: Loosen the windproof iron wedge first with four bolts through 4-? L (as shown in the above figure) is connected to the crane.
4.2 Adjustment: After installation, adjust the position of the fixing plate so that the iron wedge is placed flat and straight on the rail, and ensure the lifting height of the thruster h1
It is 8mm (at this time, the working state of the windproof iron wedge brake is in a wedged state, where the iron wedge is tightly against the wheel. If it is less than 8mm, it should be fixed by
The long hole on the fixed plate moves the brake down as a whole, and vice versa, moves the brake up as a whole Tighten the installation bolts. Then turn on the power or use the
The manual device lifts the iron wedge to a high position, adjusts the bolt (4) so that the distance between the iron wedge and the steel rail is not less than 16mm, and does not collide with the wheel,
At the same time, ensure that the installation length of the spring (6) is between 26-28 millimeters (the free length of the spring is 30mm). Iron wedge during power outage
Place it on the steel rail at a distance of approximately 50mm from the wheel. Afterwards, use the lowering valve s of the thruster to adjust the lowering speed of the iron wedge (first unscrew the anti
Dust cover, screw in the adjustment screw to slow down the descent speed, otherwise the descent speed will increase. It is recommended to delay the iron wedge pressing on the steel rail for 6 seconds after the brake is powered off
On.), After adjustment, all iron wedges should fall on the rail simultaneously after power outage.

5.1 Regularly check the working condition of the brake
During inspection, the following items should be emphasized:
The distance between the iron wedge and the steel rail should not be less than 16mm.
Check whether the components of the brake move normally and whether the adjusting nuts are tightened.
Whether the thruster works normally, whether the hydraulic oil is sufficient, whether there is oil leakage and oil seepage, and whether the insulation of the incoming wire is good.
The wear of the pin and spindle exceeds 5% of the original diameter or the ovality exceeds 0.5mm, which should be updated.
Whether the friction block is normally attached to the rail, whether the friction surface is in good condition, and whether there are greasy and dirty marks
When the tooth shape is worn, an adjusting shim should be added to make the bottom surface of the friction block 1 mm higher than the ground of the iron wedge. When the tooth shape is worn more than half, it should be replaced or repaired
Friction block.
During maintenance, connect the power supply or use a manual device to lift the iron wedge to a high position, and take out the pin (16) from the pin hole 15 and place it in the pin hole (17)
At this point, the windproof iron wedge is in the released state for maintenance purposes.
6.1 As the windproof iron wedge brake operates in one direction, it needs to be installed symmetrically. So one crane should be equipped with at least four windproof iron wedge brakes
Or install 8, 12, or 4N units according to actual needs (N is a constant).
6.2 Pay attention to the installation position of the windproof iron wedge brake. The correct thing is that when the windproof iron wedge brake in a certain direction acts, its point of action should be
After the center of gravity of the crane (relative to the direction of crane operation). If some are in front and some are behind, the descent on the thruster should be adjusted
The valve causes the windproof iron wedge brake behind the center of gravity of the crane to brake first.
When the windproof iron wedge brake operates normally, the crane should be completely stopped before the iron wedge falls onto the track to avoid unnecessary damage to the iron wedge
Impact (excluding emergency braking), thereby extending the service life of the friction block.
6.4 In the event of a sudden storm, the windproof iron wedge brake is in an emergency braking state, and the traveling mechanism of the crane should be connected to the windproof iron wedge brake
Simultaneously cutting off the power and locking the wheels provides safety protection.
