Detailed description of the invention
Now by reference to the accompanying drawings, the invention will be further described.
As shown in Figure 1 and Figure 2, this improved type winch brake device comprises driving seat 1, the torsion spring seat of honour 2, torsion spring 3, lower 4 of torsion spring, braking fork 5, nest 6, braking sleeve 7, described driving seat one end side face is provided with fan-shaped flange 101, drive the seat other end to be provided with the spacing breach 102 being rectangle, drive seat middle part to be provided with flat hole 103, one end, the torsion spring seat of honour is provided with seat of honour quadrant block 202 and the seat of honour hooks groove 201, and other end inner side in the torsion spring seat of honour is provided with circular groove 203, is provided with limiting stopper 204 in circular groove.Torsion spring two ends are provided with the hook 301 bending inwards.The lower side face of torsion spring is provided with a lower quadrant block 402, and lower seat quadrant block is provided with lower and hooks groove 401, and the lower one end of torsion spring is provided with the spacing block set 403 of parallelogram.Braking fork one end is provided with hexagon ring axle 501, and the other end is provided with fan-shaped bump 502.The concrete structure of this winch brake device is connected to: the torsion spring seat of honour is passed in the one end that drives seat to be provided with spacing breach, drive the fan-shaped flange of seat to coordinate and be rotation-limited structure with circular groove, the limiting stopper at the torsion spring seat of honour, the seat of honour that the hook of torsion spring one end is plugged in to the torsion spring seat of honour hooks in groove; The spacing block set of the lower one end of torsion spring is coordinated with the spacing breach that drives seat, and the hook of the torsion spring other end is plugged in lower hook groove of lower of torsion spring; A lower quadrant block of lower of the seat of honour quadrant block at the torsion spring seat of honour and torsion spring is coordinated and is rotation-limited structure with the fan-shaped bump of braking fork one end, and seat of honour quadrant block does not engage with a lower quadrant block, i.e. not interlock between seat of honour quadrant block and a lower quadrant block; Finally the driving seat connecting, the torsion spring seat of honour, torsion spring, lower of torsion spring, braking fork, nest are placed in braking sleeve, nest is limited in braking sleeve one end, and braking fork is provided with one end of hexagon ring axle and stretches out nest.Below the i.e. whole fitting process of this winch brake device.
Taking this winch brake device installation method as example, principle of work of the present invention is briefly described.When use, capstan winch axle drive shaft connects the driving seat of winch brake device, and in winch brake device, the hexagon ring axle of braking fork connects capstan winch output shaft.In the time that capstan winch axle drive shaft drives driving seat clockwise direction to rotate, drive the fan-shaped flange of seat to drive the limiting stopper in the circular groove of the torsion spring seat of honour, the torsion spring seat of honour is clockwise rotated, the seat of honour at the torsion spring seat of honour hooks groove and drives torsion spring hook to tighten up direction action towards torsion spring, it between torsion spring and braking sleeve, is now clutch state, the seat of honour quadrant block at the torsion spring seat of honour will further drive the fan-shaped bump of braking fork, and braking fork is clockwise rotated, and realizes the cw work of capstan winch.In the time that capstan winch axle drive shaft drives driving seat to rotate counterclockwise, drive the spacing breach of seat to drive the spacing block set of lower of torsion spring, lower of torsion spring is rotated counterclockwise, lower the hook groove that torsion spring is lower drives torsion spring hook to tighten up direction action towards torsion spring, it between torsion spring and braking sleeve, is now clutch state, the lower quadrant block that torsion spring is lower will further drive the fan-shaped bump of braking fork, and braking fork is rotated counterclockwise, and realizes the conter clockwise work of capstan winch.Above process, is the process of capstan winch rotating work.In the time of capstan winch shutdown operation, capstan winch axle drive shaft stops operating.In the time of the stall of capstan winch output shaft cw, the fan-shaped bump of braking fork drives a lower quadrant block of lower of torsion spring, lower of torsion spring is clockwise rotated, lower the hook groove that torsion spring is lower drives torsion spring hook to move towards torsion spring tensioner direction, now in torsion spring and braking sleeve, wall friction is held tightly, form drum and stop, realize the clockwise brake of capstan winch.In the time of the stall of capstan winch output shaft conter clockwise, capstan winch output shaft drives braking fork to rotate counterclockwise, the fan-shaped bump of braking fork drives the seat of honour quadrant block at the torsion spring seat of honour, the torsion spring seat of honour is rotated counterclockwise, the seat of honour at the torsion spring seat of honour hooks groove and drives torsion spring hook to move towards torsion spring tensioner direction, now torsion spring and braking sleeve friction held tightly, forms drum and stops, and realizes the brake of capstan winch anti-clockwise.Above process, is the process that capstan winch rotating is braked.
Above principle of work, be in fact the hook that utilizes the seat of honour at the torsion spring seat of honour to hook lower of lower of groove, torsion spring to hook groove and clamp torsion spring two ends, under two-sided clamping is stressed, drive torsion spring is to radial dilatation or reversing sense contraction, when in torsion spring expansion and described braking sleeve when wall friction, realize braking state; In the time that torsion spring shrinks with the non-friction of braking sleeve inwall, remove braking state.This two-sided clamping is stressed to be connected and compares with the two ends hook short range before improvement, has increased the moment of hook, has improved working stability.
