Abstract
The utility model relates to a broken rope protecting device in hoisting and lifting apparatus, comprising a balance beam component, a draw rod component, an eccentric wheel component, and a guide wheel component. When the weights are hoisted and lifted, the accident of the wire rope suddenly breaking occurs, during the moment of the weights fall, the spring in the draw rod component automatically pulls the eccentric wheel to rotate, the eccentric wheel is caused to tightly clamp the guide rail, the frictional force is larger and larger, thereby, the falling weights are braked, and the action of complete braking is achieved. The utility model has the advantages of safety, high sensitivity, good braking performance, wide universality, and simple structure, which is suitable for headframes, portal frames, or well winches with various tonnages and various types.
Description
The utility model relates to rope broken protector in the lifting lifting means.
Rope broken protector generally adopts spring pin shaft type and wedge-type broken rope protector in the lifting lifting means at present; these two kinds of protector actions are unreliable; sensitivity is not high; often error; and owing to impulsive force in the use is very big; tend to damage well cabinet frame equipment, even fatal crass's heavy accident takes place.If resume work, will exert great efforts and the time takes parts apart and reinstalls.
The purpose of this utility model provides a kind of broken rope protector, and the moment of rope-broken accident can take place when lifting, will check down the weight that falls, and has protected equipment and personnel's safety effectively.
The utility model is finished as follows: the equalizing bar assembly is installed on the two tanks of the left and right sides, is made of equalizing bar, axle, steel wire cutting ferrule, cage joint hinge, nest.Equalizing bar is captiveed joint with pull bar across on casing; Two pull bars of a casing, its screw thread external part is connected with nut with equalizing bar, and its lower end and eccentric brake wheel one end flexibly connect, and constitute rod assembly by pull bar, plus-minus screw nut, spring, spring washbowl; Between eccentric brake wheel and the track adjusting wheel guide rail is arranged, track adjusting wheel is up-and-down movement in guide-track groove, and eccentric brake wheel moves on the guide rail lateral surface, and each casing is installed two track adjusting wheels, and eccentric brake wheel and track adjusting wheel are clamped the two sides of guide rail respectively; Constitute eccentric wheel assembly by eccentric brake wheel and eccentric shaft, constitute guide wheel assemblies by track adjusting wheel, axle and bearing.
Just often eccentric wheel can not play brake action, have only when certain reason generation, when the steel rope that hangs weight ruptures suddenly, equalizing bar that is connected with steel rope and coupled pull bar all are in the state of not stressing, the spring that is enclosed within this moment on the pull bar promotes the eccentric wheel rotation, friction force between eccentric wheel and the guide rail side is increased rapidly, and casing decline more, this friction force is just big more.The cage of tenesmus is checked rapidly, played complete brake action.
The utility model contrast conventional art has following advantage: safe and reliable, highly sensitive, deceleration and stopping performance is good, and commonality is wide, and is simple in structure, is applicable to various tonnages and various types of well cabinet frame, portal frame or well winch lifting means.
Below with reference to accompanying drawing the utility model is further described.
Fig. 1 is the utility model cut-open view of final assembly.
With reference to Fig. 1, on the two tanks (15) that metal sheet is made, the equalizing bar assembly is installed, by two equalizing bars (5) across on two tanks (15), the equalizing bar assembly is by two equalizing bars (5), cage joint hinge (1), axle (3), steel wire cutting ferrule (2) and nest (4) constitute, axle (3) is captiveed joint with two equalizing bars (5), cage joint hinge (1) and movable the cooperation are installed on it, there are steel wire cutting ferrule (2) and captive joint in cage joint hinge (1) both sides, nest (4) is installed in steel wire cutting ferrule (2) outside, and be connected with axle (3) screw, play the fixed position effect.Equalizing bar (5) is connected with rod assembly, rod assembly is made of pull bar (6), plus-minus screw nut (7), spring (8) and spring washbowl (9), pull bar (6) is captiveed joint with the nut of equalizing bar (5), pull bar (6) lower end and eccentric brake wheel (10) flexibly connect, spring (8) and washbowl (9), plus-minus screw nut (7) mainly play spring (8) the telescopic location effect of adjusting.Eccentric brake wheel (10) and camshaft (11) constitute eccentric wheel assembly, and wheel (10) cooperates with axle (11) is movable between the two, and axle (11) is arranged on the centre symmetry line top of wheel (10).Guide wheel assemblies, constitute by track adjusting wheel (12), guide wheel axle (13) and bearing (14), track adjusting wheel (12) is slided in the groove of guide rail (16), track adjusting wheel (12) is clamped guide wheel (16) two sides respectively with eccentric brake wheel (10), track adjusting wheel (12) and bearing (14) close-fitting, bearing (14) and guide wheel axle (13) close-fitting, track adjusting wheel (12) is rotated around axle (13), in each casing (15) two track adjusting wheels (12), two eccentric brake wheels (10) and two pull bars (6) can be installed, also can adopt 1 separately.Eccentric brake wheel (10) is made fan-shaped.
When hoisting heavy; if for a certain reason; steel rope takes place to rupture suddenly; the tenesmus accident takes place in weight and whole lifting appliance immediately; at this moment; with the pull bar (6) on the steel rope bonded assembly equalizing bar (5); become the state of not stressing on it; spring (8) on the pull bar (6) promotes eccentric brake wheel (10) and rotates around camshaft (11) from the deflated state to the relaxation state, makes between wheel rim and guide rail (16) side and produces friction force; and friction force is increasing; tenesmus cage and weight are checked rapidly, played the safety arrestment effect, protect the safety of personnel and equipment effectively.
After the eliminating accident, again after connecting steel rope, cage and weight are up promoted a bit, just make pull bar (6) stressed eccentric brake wheel (10) pull-up, rotate around camshaft (11), the center that makes wheel shaft (11) diminishes to the radius of the wheel rim of eccentric brake wheel (10), thereby makes eccentric brake wheel (10) and guide rail (16) side friction power reduce to zero, on the contrary friction force along with the wheel rim of eccentric brake wheel (10) to the increase of the radius between the camshaft (11) and increase.
