Abstract
The utility model relates to a double-brake mechanism for hoisting winches, belonging to the field of industrial machinery. The double-brake mechanism for hoisting winches is mainly used for brake devices of hoisting machines and tools, such as mines, ports, well sites, etc. The double-brake mechanism for hoisting winches is mainly characterized in that a single-side brake drum of an original pneumatic hoisting winch is changed to a double-side brake device, that is to say, one side of the brake drum is provided with a foot brake device, and the other side is provided with a hand brake device. A brake system has a double-safety effect by using the double-brake mechanism. The hoisting winches can carry out operation of hoist or lowering discretionally. The double-brake mechanism for hoisting winches is safe, and unexpected accidents are prevented from happening.
Description
Winch dual brake mechanism belongs to the industrial machinery field, and it is mainly used in mine, harbour, well site etc. and hangs the brake gear that rises facility.
What have use now usually is pneumatic puffer, as propulsion source, is used to lift by crane midget plant by pressurized air, and the brake drum of air winch is the single face brake drum, and two kinds of forms are often arranged, and a kind of is the single face parking brake, and another kind of is that the single face foot is stopped.The stopping brake lock characteristics are winch drum can be checked and made suspension heavy weight to leave the back weight at operating personal not fall, and brake has auto-lock function, then operate inconvenience but be used for a brake, and brake weight is little.Foot brake characteristics are that point is stopped conveniently, and still, the operator can not leave when foot touched on the brake, and did not possess the auto-lock function of brake, so dangerous.Because vibration is bigger, tripping automatically causes in the lifting to run out of steam suddenly the clutch handle of air winch easily, and object is hurtled down, and easily has an accident when winch is worked.
The purpose of this utility model is to create a kind of dual brake car insurance system, makes air winch easy to operate when the lift heavy thing, and the brake flexibility and reliability ensures lifting operation safety.
Winch dual brake mechanism is achieved in that changes a social system two-sided brake gear to the single face brake drum of original air winch, one side promptly at the sufficient brake gear of installing of brake drum, at the another side of brake drum lever brake is installed; The foot brake gear is made up of the several parts of pull bar, brake strap, pull back spring and pedal.During work, only need pedal just to brake by point, brake automatically terminates when lifting pin.Lever brake is made up of brake handgrip, pull bar and pull back spring (comprising brake strap).During work, only need depress the brake handgrip and can check.In addition, spring traction is installed at air winch clutch handle place, is fixed on lid screw place, limit, handgrip is subjected to spring tension just to be difficult for breaking away from, and prevents contingency.
With this dual brake mechanism, because stopping, both can operate separately on the parking brake foot, but mating reaction again, brake system has the effect of double insurance; Winch can lift by crane or transfer operation arbitrarily, and is safe and reliable.
Advance an explanation below in conjunction with accompanying drawing:
Fig. 1 is the right side scheme drawing of this mechanism, and Fig. 2 is a front view, and Fig. 3 is the left side scheme drawing.
Accompanying drawing is explained:
1. handgrip 2. pull bars 3 clutch handles 4. springs 5 pull back springs
6. brake drum 7. brake drums 8. brake straps 9. pull bars 10. pull back springs
11. pedal 12. gears case 13. gas motors 14 are changed hands handle 15. cylinders.
As the handgrip among the figure (1) cylinder lever connecting rod (2) and pull back spring (5) and brake strap part, pull bar (2) is connected with brake drum (7), consist of lever brake, another side at cylinder (15) is installed sufficient brake gear, it connects brake strap (8) by pull bar (9) top, the bottom connects pedal (11) and pull back spring (10), brake drum (6) locate with gas motor (13) with change hands handle (14) and be connected.Opposite side in this dual brake mechanism is installed clutch handle (3), locate mounting spring (4) at clutch handle (3), and it is fixed on limit lid screw place, clutch handle (3) is subjected to this spring tension traction control, and the danger unexpected out of control that causes clutch handle (3) escape to cause by the winch vibration just can not take place.
If this winch dual brake device of implementation and operation is used for hoisting heavy need suspend the time, can adopt sufficient brake gear part, if when needing the long-time hovering of hoisting heavy, cylinder checked cylinder and lock by then available lever brake.When if suspension heavy weight weight is heavier, but parking brake and foot stop and be used, brake is just more safe and reliable.Adopt above dual brake device, can not lock the defective of cylinder when having solved the ineffective sometimes or brake of original winch brake, safe and reliable.
Claims (2)
1, winch dual brake mechanism is made of two-sided brake gear, it is characterized in that hand brake device is by handgrip (1) cylinder lever connecting rod (2) and pull back spring (5) and brake strap part, pull bar (2) is connected with brake drum (7), another side at cylinder (15) is installed sufficient brake gear, it connects brake strap (8) by pull bar (9) top, the bottom connects pedal (11) and pull back spring (10), brake drum (6) locate with motor (13) with change hands handle (14) and be connected braking mechanism one side installation clutch handle (3).
2,, it is characterized in that clutch handle (3) locates mounting spring (4), and it is fixed on lid screw place, limit by the described winch dual brake of claim 1 mechanism.
