Description
Technical Field
The utility model relates to a bucket-wheel stacker reclaimer hoist engine wire rope slack rope protection device.
Background
The bucket-wheel stacker-reclaimer plays a crucial role in the whole production process of a power plant, a pitching steel wire rope is frequently separated from a top fixed pulley or winding of a winding drum is disordered in the operation process of the bucket-wheel stacker-reclaimer, and especially at night and in severe weather, if the rope can not be found to be loosened in time, the consequence can be imagined.
Disclosure of Invention
The utility model aims at providing a bucket-wheel stacker reclaimer hoist engine wire rope slack rope protection device.
The above purpose is realized by the following technical scheme:
the utility model provides a bucket-wheel stacker reclaimer hoist engine wire rope slack rope protection device which constitutes and includes: the locking device comprises two supports, two locking devices are connected between the two supports, each locking device comprises two buffer pull boxes, two limit switches and a pull rope, each buffer pull box is a hollow cylindrical box with cylindrical holes at two sides, the two buffer pull boxes are respectively fixed on vertical plates of the two supports, a sliding block is arranged in each buffer pull box, the two sliding blocks are connected through the pull rope, a sliding rod is fixed on each sliding block, a spring is sleeved on each sliding rod, and the end part of each sliding rod is fixed with a pull rod;
the side of the vertical plate is fixed with a bottom plate, the bottom plate is fixed with the limit switch, and the deflector rod is attached to a rotating arm of the limit switch.
The two anti-loosening devices are arranged in a staggered mode.
The support comprises a bottom frame and a vertical plate, and the vertical plate is fixed on the bottom frame.
Has the advantages that:
1. the utility model discloses not hard up whereabouts when wire rope breaks away from the top fixed pulley can be taken on the stay cord for the stay cord downwarping, the slider slip is being drawn at the stay cord both ends, makes the driving lever stir limit switch's rotor arm and rotates, and limit switch normally closed contact disconnection makes the hoist engine outage, can in time discover wire rope and break away from the top fixed pulley, prevents unexpected emergence.
2. The utility model discloses set up two locking devices, two locking device dislocation arrangements are unanimous with wire rope's inclination, take on two stay cords after wire rope whereabouts, indicate after the limit switch that can two locking devices all switches on that wire rope breaks away from the top fixed pulley, can prevent that other debris from hanging to lead to its transmission error signal on the stay cord.
Description of the drawings:
FIG. 1 is a front view of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
FIG. 3 is a side view of the present invention in use;
in the figure: 1. pulling a rope; 2. a buffer pull box; 3. a slide bar; 4. a deflector rod; 5. a limit switch; 6. a base plate; 7. a vertical plate; 8. a chassis; 9. a slider; 10. a spring; 11. a steel cord.
The specific implementation mode is as follows:
example 1:
the utility model provides a bucket-wheel stacker reclaimer hoist engine wire rope slack rope protection device which constitutes and includes: the anti-loosening device comprises two supports, wherein two anti-loosening devices are connected between the two supports, each anti-loosening device comprises two buffering pull boxes 2, two limit switches 5 and a pull rope 1, the buffering pull boxes are hollow cylindrical boxes with cylindrical holes in two sides, the two buffering pull boxes are respectively fixed on vertical plates 7 of the two supports and are fixedly welded, a sliding block 9 is arranged in each buffering pull box and is in sliding fit with the inside of the buffering pull box, the two sliding blocks are connected through the pull rope, a sliding rod 3 is fixed on each sliding block, a spring 10 is sleeved on each sliding rod, one end of each spring is fixed with the inside of the buffering pull box, the other end of each spring is fixed with the corresponding sliding rod, and the end of each sliding rod is fixed with a shift lever 4 and is fixedly welded;
And a bottom plate 6 is fixed on the side surface of the vertical plate and is fixedly welded, the limit switch is fixed on the bottom plate, and the deflector rod is attached to a rotating arm of the limit switch.
Example 2:
according to the device for protecting the wire rope of the winch of the bucket-wheel stacker-reclaimer in the embodiment 1, the two anti-loosening devices are arranged in a staggered manner.
Example 3:
according to the device for protecting the wire rope of the winch of the bucket-wheel stacker reclaimer in the embodiment 1 or 2, the bracket comprises an underframe 8 and a vertical plate, and the vertical plate is fixed on the underframe and is fixedly welded.
The working principle is as follows: as shown in fig. 3, the distance between the hoisting steel wire rope and the lower platform is 1320mm meters, the bracket is fixed on the lower platform, the pull ropes of the two anti-loosening devices are both located below the steel wire rope 11 and 3mm below the steel wire rope, when the steel wire rope is separated from the top fixed pulley, the steel wire rope is loosened and can be put on the two pull ropes, the two pull ropes are bent, the slide blocks of the buffer pull boxes on the two sides are pulled to slide in the buffer pull boxes, the slide blocks slide to enable the shift lever to shift the rotating arm of the limit switch, the rotating arm of the limit switch rotates to enable the normally closed contact of the limit switch to be disconnected, the normally closed contact of the travel switch can be connected with the control circuit of the hoisting motor to play a role of disconnecting the circuit, the hoisting motor stops working and prevents accidents, the slide blocks slide to the maximum distance of the two ends of the buffer pull boxes, and the rotating arm of the limit switch just rotates to the maximum angle at the moment, can play the guard action to limit switch, when wire rope hangs again on the top fixed pulley, the slider can the reverse slip under the effect of spring, make the stay cord be taut state again, limit switch's rotor arm can get back to initial position this moment, make normally closed contact reclose, can start the hoist engine, it leads to the slider to slide to have debris accident to hang on it at one of them stay cord, limit switch's rotor arm is stirred and also can not lead to the hoist engine to shut down, only the limit switch normally closed contact of two locking wares all breaks off just can in addition the hoist engine to shut down, can prevent that the condition of mistake shut down from taking place.
