Description

A kind of elevator that has the Jackstay type safety device
Technical field
The present invention relates to a kind of elevator that has the Jackstay type safety device, belong to the elevator technology field.
Background technology
In the existing elevator, have simple in structure, cost is low, but safety factor is very low, steel rope takes place easily broken and hang hurdle accident such as rush to summit; The safety factor that has is high, but complex structure, as adopting high technology content products such as sensor, controller, cost is high.
Summary of the invention
The technical matters that the present invention will solve provide a kind of with low cost, the elevator that has very high safety factor when simplifying structure arranged.
In order to solve the problems of the technologies described above, technical scheme of the present invention provides a kind of elevator that has the Jackstay type safety device, it is characterized in that: comprise first winch, first motor of being located on first frame is connected with first winch through first belt; First pull-cord, one end is located on second frame, and the first pull-cord other end is located on first winch through movable pulley; Movable pulley links to each other with elevator chamber through steel rope, elevator chamber through two strut bars respectively with the slide rail of being located at the elevator chamber both sides on slide block be connected;
Second winch is located at slide rail below, and second pull-cord, one end is located on second winch, the second pull-cord other end through two strut bars respectively with the slide rail of being located at the elevator chamber both sides on slide block be connected; Second motor of being located on the 3rd frame is connected with second winch through second belt.
Preferably, the slide rail top of said elevator chamber both sides is equipped with limiting device.
When a kind of elevator that has the Jackstay type safety device provided by the invention rises; Second motor cuts out, and starts first motor, and first motor just changes; Drive the rotation of first winch through first belt; First winch, first pull-cord traction movable pulley of reeling, and then the traction elevator chamber rises, elevator chamber drives strut bar and rises.When slide block rises to the limiting device position, first slipping of the belt, elevator chamber can't rise.If interrupt in uphill process medium power source, break down like first motor, first pull-cord is broken, and strut bar plays the fault that prevents that elevator chamber from falling at any time.During decline, second motor is opened, and first motor cuts out, and elevator chamber descends.
Compared with prior art, a kind of elevator that has the Jackstay type safety device provided by the invention has following beneficial effect:
(1) simple in structure, cost is low;
(2) belt-driving skids when overload, plays overload protective function;
(3) adopt movable pulley, play laborsaving effect, lower to the motor load Capability Requirement;
(4) slide rail is provided with limiting device, can prevent the generation of the accident of rushing to summit;
(5) elevator chamber has the protection safety device, can prevent that elevator chamber from falling.
Device provided by the invention has overcome the deficiency of prior art, and is simple in structure, and cost is low, lower to the motor load Capability Requirement, and has overload protective function, can prevent that elevator chamber from falling and the generation of the accident of rushing to summit.

The specific embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Fig. 1 is a kind of elevator structure scheme drawing that has the Jackstay type safety device provided by the invention, and described a kind of elevator structure that has the Jackstay type safety device comprises a Power Drive Unit, a safety guard and a pull device.Power Drive Unit comprises first winch 4, and first motor 2 that is fixed on first frame 1 drives 4 rotations of first winch through first belt 3.First pull-cord, 5 one ends are fixed on second frame 13, and first pull-cord, 5 other ends are walked around movable pulley 6 and are wound on first winch 4.Steel rope 7 one ends link to each other with movable pulley 6, and steel rope 7 other ends link to each other with elevator chamber 9.
9 times companies of elevator chamber protection safety device.Elevator chamber 9 is hinged with strut bar 10, and strut bar 10 is hinged with slide block 11 again, and slide block 11 can slide up and down along the slide rail 12 of elevator chamber 9 both sides.A limiting device 8 is respectively established on slide rail 12 tops.Supported on both sides bar 10, slide block 11, slide rail 12, limiting device 8 relative elevator chamber 9 complete symmetric arrangement.
Pull device is arranged identical with Power Drive Unit.Pull device comprises second winch 15; Second winch 15 is positioned at slide rail 12 belows; Second pull-cord, 18 1 ends are wound on second winch 15, second pull-cord, 18 other ends through two strut bars 10 respectively with the slide rail 12 of elevator chamber 9 both sides on slide block 11 be connected.Second motor 17 that is contained on the 3rd frame 14 is connected with second winch 15 through second belt 16.
During rising, pull device is closed, and starts first motor 2; First motor is just changeing 2, drives 4 rotations of first winch through first belt 3, first winch, 4 coilings, first pull-cord, 5 traction movable pulleys 6; And then traction elevator chamber 9 rises 10 risings of elevator chamber 9 drive strut bars.When slide block 11 rose to limiting device 8 positions, first belt 3 skidded, and elevator chamber 9 can't rise.If interrupt in uphill process medium power source, break down like motor 2, first pull-cord 5 is broken, and the protection safety device plays the fault that prevents that elevator chamber 9 from falling at any time.Protection safety device principle is following:
Fig. 2 is a Jackstay type safety device fundamental diagram; If θ is for connecting strut bar 10 and two slide block 11 angles connected horizontally of elevator chamber 9 and slide block 11, m is the length of connection elevator chamber 9 with the strut bar 10 of slide block 11, and L is the distance of two slide blocks 11; φ is the friction angle between slide block 11 and the slide rail 12; F is the friction coefficient between slide block 11 and the slide rail 12, if slide block 11 has self-locking action, then has
tanθ<tanφ=f
2 m 2 - L 2 / 4 / L < f
As long as the relational expression above satisfying can guarantee slide block 11 self-lockings.
During decline, pull device is opened, and first motor 2 cuts out, and elevator chamber 9 descends.
