Description

The two basket elevators of dual fail-safe

What the two basket elevators of the utility model dual fail-safe related to is the improvement that the building construction building site is promoted the hoisting mechanism of weight.

At present, promote, lift the elevator of weights such as sandstone, cement, precast plate on the building construction building site, constitute by frame, wire reel, wire rope, fixed pulley, motor, reductor, hanging basket etc., it has following shortcoming the elevator of this structure: the one, only with a hanging basket, a hanging basket is only used steel cable, if wire rope one is disconnected, hanging basket just falls, do not have emergent, remedial measure, often have an accident; The 2nd, motor switch often breaks down, as: this disconnection motor switch and can not disconnect the time, often cause hanging basket to rush to summit; The 3rd, the wire rope of hanging basket on a reel, wire rope self friction and damaging; The 4th, have only a hanging basket, inefficiency.

The purpose of this utility model is the shortcoming that exists in the prior art for overcoming, and provides a kind of dual fail-safe two basket elevators, to increase work efficiency reliable operation, security insurance.Why two-way safeguarding function is arranged mainly is to have taked two measures, the one, the length of steel wire rope of two hanging baskets of connection, be designed to a hanging basket when the discharging of elevator assigned address (tip position), another hanging basket just lands, promptly calculate the electric switch of the winding plant of elevator, controlling organization is malfunctioning, perhaps operator's work mistake or general idea, motor works on, and one of them hanging basket lands, wire rope and reel lose friction, wire rope are run out of steam motor, lifting appliance is idle running just, thereby hanging basket will not rush to summit, and this is an insurance function; Another is that three wire rope are arranged on the hanging basket, it is overweight promptly to calculate lifting object, wherein one has broken, other two wire rope can play salvage, hanging basket can not fall down at once, and the operator can take emergency measures and remedial measure after finding if having time, this is second insurance function, so this elevator is named as the two basket elevators of dual fail-safe.

The utility model has the advantages that: one, hanging basket can never be rushed to summit, just in case disconnected steel cable, endure, reliable operation has the dual fail-safe effect, and two, hanging baskets are in the top discharging, another hanging basket is feeded in the bottom, and work can be carried out simultaneously, so high efficiency; Three, simple in structure, install easily, easy to use; The 4th, the wire rope of using on the hanging basket does not have self friction, can not make wire cable rupture because of friction.

The technical scheme that realizes the purpose of this utility model is such:

The two basket elevators of dual fail-safe are fixed on the three-flute fixed pulley of frame top by frame 1, the fixed pulley of frame lower, promote the winding plant of hanging basket, connect a left side, the wire rope II of right hanging basket, two-wheel assembly pulley 4 on the height-regulating device of adjustment hanging basket height, pulley K, fixed pulley n, hand cable regulator 2, formations such as wire rope I, be connected hanging basket on the wire rope II under the control of winding plant, a wire rope II traction left side, right hanging basket moves up and down, promote material, hand cable regulator 2 on the height-regulating device, adjust the hanging basket height, connecting a left side, the length of the wire rope II between the right hanging basket, be adjusted to one of them hanging basket when unloading material at the top, another hanging basket is adorned material on the ground, promptly a hanging basket is when the height of regulation, and another hanging basket just drops on the ground.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is the structural representation of the two basket elevators of dual fail-safe

Fig. 2 is the winding plant schematic perspective view;

Fig. 3 is connected H to view for fixed pulley A, B, C, D, the E that the top has three grooves with the wire rope II;

Be provided with crossbeam on the top of frame 1 among Fig. 1, be fixed with fixed pulley A, fixed pulley B, fixed pulley C, fixed pulley D, fixed pulley E on it, the frame below is provided with fixed pulley F, fixed pulley G, all having with top sheave can be around three groove of wire rope.

The described windlass device of Fig. 2 is installed on the ground, is made of motor 6, reductor 7, pedestal 9, six groove great wheels 10, three-flute truckle 8.Six groove great wheels 10, three-flute truckle 8 are fixed on the pedestal 9.

Among Fig. 3, three wire rope II are in the groove of fixed pulley A, B, C, D, E.

Below just Fig. 1 fixed pulley on wire rope II and the frame 1 is described, hanging basket, six groove great wheels 10 on the elevator unit, three-flute truckle 8, the annexation of two-wheel assembly pulley on the height-regulating device: an end of wire rope II ties up on the left hanging basket lashing point admittedly, the other end is walked around first groove on the fixed pulley A, behind first groove of fixed pulley B, down walk around first groove of fixed pulley F, walk around first groove of six groove great wheels 10, walk around first groove of three-flute truckle 8 again, unrolled again again behind second groove of six groove great wheels 10, up walk around first groove of fixed pulley G, then up walk around fixed pulley C first groove, down walk around top sheave first groove on the two-wheel assembly pulley 4, upwards walk around first groove of fixed pulley D again, first groove on the fixed pulley E last down is connected with first sling point on the right hanging basket.Connection for all the other two wire rope II is carried out with quadrat method by above-mentioned.Hand cable regulator 2 is installed in the below of frame 1, shake the hand on it, fixed pulley n is fixed on the frame 1, the wire rope II is looped around on the top sheave of two-wheel assembly pulley 4, and an end of wire rope I ties up on the position slightly on the lower side, stage casing of frame 1 admittedly, and the other end is walked around the pulley K of two-wheel assembly pulley 4, down walk around fixed pulley n again, unroll again to second groove of the pulley K of two-wheel assembly pulley 4,, and be fixed on this axle down directly around to the axle of hand cable regulator 2.During handle on shaking hand cable regulator 2, wire rope twines on the regulator shaft, two-wheel assembly pulley 4 down moves, and drives hanging basket and up moves, when the axle counter-rotating, two-wheel assembly pulley 4 up moves, hanging basket down moves, and by upper and lower adjusting, can control a hanging basket at the top, a hanging basket just lands, and has designed the length of wire rope II like this.

How the following describes the power that makes left and right hanging basket and weight rise to certain altitude produces: motor rotates, after the deceleration, drive six groove great wheels 10 and rotate, produce kinetic force of friction between six groove great wheels and the wire rope II, this frictional force is the power that hanging basket, weight are risen.And stiction is the trimming moment of left and right hanging basket under static state, and kinetic force of friction is greater than stiction, and hanging basket just can send material up and down.

The detailed course of work and force principal are as follows:

With right hanging basket is example, when right hanging basket fills with weight underground, when desiring to be sent to the top, starter motor, motor passes to six groove great wheels with moment, make its rotation, because of a left side, right hanging basket acts on the six groove great wheels the tension force of wire rope II, six groove great wheels produce a frictional force to the wire rope II on its rotation direction for some reason, this as power frictional force and the gravity sum of left hanging basket greater than the gravity of right hanging basket, so right hanging basket rises, left hanging basket descends, when left hanging basket drops to when just landing, right hanging basket rises to the top, and at this moment, left hanging basket and right hanging basket are to the tension force of steel rope and the mutual balance of frictional force on the six groove great wheels, right hanging basket can not be descended, also can not rush to summit simultaneously.The uphill process and the said process of left side hanging basket are similar.
