Description

Elevator column anti-dumping and cable jacking system

Technical field

The utility model belongs to the elevator column anti-dumping and the cable jacking system of a kind of building operation, mine vertical shaft, interior of building, the column anti-dumping and the cable jacking system of the two cage elevators of particularly a kind of single column.

Background technology

In the prior art, existing elevator, SS100 * 100 building hoists of the two cages of producing as Nanchang science-star's vehicle for construction limited liability company of single column, its structure is that the column top is provided with a day beam, cage is installed at the two ends of the corresponding day beam in column both sides respectively.Hoisting rope one end is connected on the cage, after the other end is walked around pulley on day beam, is mounted on traction cage lifting on the ground-surface winch down.Difference captive joint cable one end on every cage, the other end of cable is connected on the ground-surface electric appliance box.During work, when a cage is parked in ground, when the fully loaded weight of another cage was raised the rope traction and upwards moves, at this moment a column and a day beam out-of-balance condition occurred tiltedly to the inclination of load-carrying cage, and tilt quantity will have an accident above permissible value.The cable that one end is connected on the cage also rises disorderly arbitrarily or lands with cage is lax, causes lifting meeting in service to be colluded to hang or landed cage by other protrusions and pushes down accident.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of elevator column anti-dumping scientific and reasonable for structure, safe and reliable, easy to install and cable with the cage jacking system.

The technical solution of the utility model is: installing two on pouring weight top coorespondingly has an axis hole back plate, and pulley is installed in two rotating shafts between the back plate, and slip ring is installed in the pouring weight both sides.The middle part of it beam is installed in column top, and a cage is respectively installed in the two sides at the corresponding Tian Liang of column two ends.The length of it beam exceeds two cage outside running orbits, fixing two on the termination, Tian Liang two ends separately respectively is one group guide rope one end, two guide rope other ends pass the slip ring of the pouring weight both sides of pulley when top respectively on the same group, are fixed on the basis, ground after the vertical parallel tension.Outstanding Guan Yiduan is installed on the cage, and the corresponding and close pulley notch of the other end is running orbit on one side.Cage is when ground, and cable one end is fixed on connecting circuit on the cage after penetrating outstanding pipe, after the cable other end is walked around suspended pouring weight built on stilts, fixedly is connected on the electric appliance box after penetrating arm, and cable is stressed linearity under the effect of unsettled pouring weight.Arm one end is installed in the corresponding and close pulley notch running orbit another side in middle part of column height, and the other end is fixed on the body of wall.

The specific embodiment

Embodiment: installing two on pouring weight 2 tops coorespondingly has an axis hole back plate 13, and pulley 4 is installed in two rotating shafts 12 between the back plate 13, and slip ring 3 is installed in pouring weight 2 both sides.The middle part of it beam 10 is installed in column 9 tops, and column 9 corresponding day beam 10 side faces at both ends are installed two cages 5 respectively, and the length of day beam 10 exceeds two cages, 5 outside running orbits.Fixing two on it termination, beam 10 two ends separately respectively is one group of guide rope 1 one end, and two guide rope 1 other ends are fixed on the basis, ground after passing the slip ring 3 vertical parallel tension of pouring weight 2 both sides respectively on the same group.Outstanding pipe 6 one ends are installed on the cage 5, corresponding and close pulley 4 notches of the other end are running orbit on one side, cable 14 1 ends penetrated and enter cage 5 fixing backs behind the outstanding pipe 6 and join with electrical equipment when cage 5 landed, cable 14 other ends are walked around pulley 4 backs and are hung pouring weight 2 built on stilts, penetrate arm 7 backs and fixedly be connected in the ground-surface electric appliance box, cable 14 is stressed linearity under the effect of hanging pouring weight 2.Arm 7 one ends are installed in the middle part of column 9 height, corresponding and close pulley 4 notch running orbit another sides, and the other end is fixed on the building.Its process was when the utility model used in reality: when two cages 5 of elevator were stopped ground, its column 9 and a day beam 10 were state of equilibrium.When a cage 5 rests in ground, another cage 5 fully loaded weights, at the hoisting rope 8 of walking around the head sheave 15 on day beam 10 be installed under the traction of ground winch 11 when rising, the right stress destruction of one distal process of the column 9 of elevator and day beam 10 state of equilibrium, under gravitate, they beam 10 1 ends are downward, and column 9 takes place to tilt in the allowed band.Uptrending appears in they beam 10 other ends, but two guide ropes having been strained 1 hold and can't rise, the relative equilibrium after having kept day beam 10 1 distal process right stressed, and the bending resistance of column 9 is stressed, and to become resistance to compression stressed, controls the further inclination of column 9.Same framing member pressure resistance has improved the safety of elevator column 9 greater than resistance to bending.Cable 14 makes progress, moves downwards by the guide rope 1 of the slip ring 3 of pulley 4 on rotating shaft 12 rotation pulling pouring weights 2 along two vertical parallel along with the outstanding pipe on the cage 56 makes progress, moves downwards.Cable 14 is stressed linearity under the effect of pouring weight 2, overcome cable 14 and colluded to hang by other protrusions and break by the moving range of operation that departs from of wind, and cable 14 is lowered by when landing and lands cage 5 and push down and cause the accident.The alleged cage of the utility model can also be the car of elevator, the cage of mine vertical shaft.

The utility model compared with prior art, have characteristics such as scientific and reasonable for structure, easy to install, safe and practical, be existing building construction, mine, the novel column anti-dumping of industrial elevator and cable jacking system.
