Abstract
The invention relates to the technical field of manufacturing of elevator equipment, and discloses a fall-prevention safety protection device for a vertical lift elevator. The fall-prevention safety protection device comprises safety hanging hook boxes and spring steel wire rope sets; the safety hanging hook boxes are fixedly arranged on two sides of a cage; and the spring steel wire rope sets are arranged on two sides of a well. A plurality of spring steel wire rope sets are arranged on two sides of the well in a vertical direction; and when the elevator overspeeds during running, electromagnets are electrified, hanging hooks in the safety hanging hook boxes are rotated out of box bodies to hook the spring steel wire rope sets which are closest to the well, and two ends of each steel wire rope are provided with springs, so that a certain buffering function can be exerted, and the personnel safety can be guaranteed. After faults are removed, the electromagnets are disconnected from a power supply, and the hooks return into the box bodies under the action of gravity of balancing weights, and the elevator can recover in short time.
Description
Technical field
The present invention relates to lift facility manufacturing technology field, is a kind of Fall-prevention safety protection device for vertical lift elevator.
Technical background
Along with increasing of skyscraper, the use of elevator increases thereupon, for ensureing lift running safety, must assemble elevator fall protection equipment.Nowadays, in the lift facility come into operation, elevator fall arrest realizes primarily of devices such as limiter of speed, safety tongs and hoistway bottom buffer springs.The speed of car by limiter of speed at any time Monitoring and Controlling, when there is supervelocity situation, can send signal in time, then produces mechanical action and cut off power supply circuits, traction machine is braked.If elevator still cannot be braked, then car is forced stop by the safety tongs action being arranged on cage bottom.The impulsive force of colliding surface when the buffer spring device of hoistway bottom can reduce used during elevator falling, but limited efficiency.Although elevator is equipped with above-mentioned two kinds of fall protection equipments, but can not avoid the generation of used during elevator falling accident completely, its reason has 3 kinds.
1. elevator overload runs;
2. during elevator installation and maintenance, to steel wire rope, rope sheave, band-type brake etc. debug unreasonable caused by;
3. elevator wire rope comes off or ruptures.
Summary of the invention
In order to prevent the used during elevator falling accident of above-mentioned situation, the invention provides a kind of vertical lift elevator fall protection equipment independent of existing safe-guard system, as the additional protection means outside existing safety guarantee equipment, realizing duplicate protection.
Vertical lift elevator fall protection equipment is achieved in that and comprises: safety hook box, spring steel wire rope group.
Spring steel wire rope group is made up of steel cable, two springs, two tripods and two block plates.Steel wire rope one end is through tripod with holes, then after passing from spring center, be fixed on a block plate, the other end is assembled with identical structure.
Two pieces of tripods by stretching for steel wire rope level, and are fixed on elevator hoistways both sides.
Described safety hook box, fixed symmetrical is arranged on car both sides, and its inside comprises: a hook that can sway; Be fixed on the balancing weight of hook bottom; And one block of electromagnet.
Hook bottom can pick up by electromagnet after powered up, hook is rotated around the axis, the part of the top buckle of hook is produced hook box.
When elevator overspeed descending, electromagnet receives the signal or manual command that overspeed testing apparatus sends, and electromagnet is energized, hook is made to rotate out hook box, link up with the steel wire rope caught in hoistway wall, because steel wire rope two ends are provided with spring, have certain cushioning effect.
The signal that overspeed testing apparatus sends, can by " a kind of vertical lift elevator overspeed detection sensor ", and application number is the patent of invention of 201210341764.8, or other devices with identical speed measuring function send.Manual command artificially starts emergency stop switch in cab, makes electromagnetic actuation.
In vertical hoistway, install multiple spring steel wire rope group, once elevator overspeed is descending, hook can catch on wherein one group of steel wire rope at short notice.
After trouble shooting, electromagnet power-off, lift car is by pull-up is a part of slightly, and hook under gravity, retracts in hook box by balancing weight.
Beneficial effect of the present invention:
The present invention can make the attachment device of elevator safety protection facility, for the safety of elevator ride personnel serves Pleiotropic Protections.
The present invention adopts spring steel wire rope group, because steel wire rope two ends are provided with spring, has certain cushioning effect to lift car.
Adopt balancing weight to combine in the present invention, after trouble shooting, under the effect of balancing weight, hook can be retracted in box easily, can recover elevator at short notice and run.
The present invention adopts multiple spring steel wire rope group on hoistway vertical direction, after elevator overspeed monitoring device sends signal, hook can tangle the steel wire rope on wall in a short period of time, avoids elevator speed and strengthens further, produces situation more rambunctious and occurs.
This technology is also applicable to all kinds of lift, tunnel slope track car.

Detailed description of the invention
As shown in Figure 1, Fall-prevention safety protection device for vertical lift elevator comprises: safety hook box 3; Spring steel wire rope group 4.Safety hook box 3 is fixedly mounted on lift car 2 both sides, and spring steel wire rope group 4 level is stretching to be arranged in elevator hoistways side walls 1.
As shown in Figure 2, spring steel wire rope group 4 is made up of with steel plate 8 steel cable 5, spring 6, tripod 7.Steel wire rope 5 one end is through the circular hole 9 of tripod 7, then after passing from spring 6 center, be fixed on a block plate 8, steel wire rope 5 other end is assembled with identical structure.
In elevator hoistways side walls 1, vertical equidistant installation multiple spring steel wire rope group 4.
As shown in Figure 3, two pieces of tripods 7 by stretching for steel wire rope level, and are fixed on elevator well channel wall 1.
As shown in Figure 4, safety hook box 3 comprises: a hook box shell 13; One can around the shaft 15 rotate hooks 14, be fixed on the balancing weight 10 bottom hook 14; Be fixed on one block of electromagnet 11 of hook box 3 bottom sides; And hook box shell 13 is fixed on the screw hole 12 of lift car 2 side.
When the non-starting state of device, due to the Action of Gravity Field of balancing weight 10, hook 14 is always inner at hook box 3.
As shown in Figure 5, when elevator overspeed descending, electromagnet 11 is energized, and picks up bottom hook 14, and hook 14 rotates out hook box 3, and hook 14 catches on the steel wire rope 5 in hoistway wall.
After trouble shooting, electromagnet 11 power-off, lift car 2 is by pull-up is a part of slightly, and hook 14 under gravity, retracts in hook box 3 by balancing weight 10.
