Description
Technical field
This utility model is related to elevator technology field, and in particular to a kind of electric barring equipment of elevator traction machine.
Background technology
The oppressive event of elevator faults happens occasionally, when elevator occurs to have a power failure or elevator faults are oppressive, existing to have machine room electricity
Ladder rescue method be：The brake of manual unlocking elevator traction machine is declutched wrench, if the weight at traction machine two ends (i.e. car with
Counterweight) difference than it is larger when, car can move to level position because of the automatic car slipping of gravitational difference, open layer sedan-chair in the level position
Door, makes trapped personnel be rescued；If the weight difference at traction machine two ends is not very big, i.e., car reaches relative equilibrium shape with counterweight
State, now must force car to move on to level position by external force, i.e. jiggering mode forced rotating traction sheave.
Standard GB/T 7588《Elevator is manufactured and installs safety standard》Specify in 12.5, if moved up equipped with volume
Determine the operating physical force needed for the car of loading capacity and be not more than 400N, elevator driving host should install manual emergency operation device, so as to
Borrow is smooth and car is moved to a stop by the handwheel without spoke；If the power that 12.5.1 specifies is more than 400N, machine
Room planted agent arranges the electrically-operated arrangement of a urgent electric operation for meeting 14.2.1.4 regulations, i.e. electric barring equipment and comes real
Now urgent jiggering rescue.
Elevator be equipped with hand-barring when, even if by national standard requirement the operating physical force moved up needed for car not
More than 400N, rescue works are generally also to waste time and energy, because urgent jiggering operation needs to wait for professional elevator service personnel and reaches
Scene is carried out, the waiting time sometimes be up to a few hours, and hand turning generally need many people's compounding practice tractors declutch manually and
Carrying out, it realizing, is to realize being not more than 400N (about that tractor hand-barring is by larger speed reducing ratio to handwheel
Jiggering operating physical force 40kg), handwheel need to rotate many circle ability elevator and reach level position, and jiggering operation is generally needed
Many people coordinate in turn.
In addition, many high-end houses are typically using the design at a single terraced i.e. one terraced family of directly registering one's residence, only ground floor at present
Public territory could be connected with subterranean layer, when oppressive failure occurs in elevator, by traditional rescue mode, rescue personnel cannot be random
Rescued in the elevator of certain level position (owner's family no one is unwilling to open the door), it is necessary to drop to from failure layer
Ground floor implements rescue again, and high-end house register one's residence employing elevator generally specified carrying personnel it is few, car is light, traction machine pair
Heavy, elevator can rise by deadweight, also increase the difficulty of hand turning, elongated rescue time.
Machine-roomless lift is limited because of working place, does not generally configure Manual jigger mechanism, is only furnished with traction machine remote brake release
Control device, can only utilize car and the gravitational difference automatic moving of counterweight to realize that jiggering rescues people to level position.
It is because of the deficiency of above-mentioned hand turning, if adopting electric barring mode, not only time saving and energy saving, when greatling save rescue
Between, even jiggering rescue operation can also be realized using remotely control in the future, i.e., in the feelings at the professional scene of cannot arriving in the very nick of time
Under condition, remote guide quickly solves the problems, such as rescue.
The patent of invention document of publication number CN 104401830A discloses one kind the electronic rescue jiggering dress of machine room elevator
Put, ultimate principle is to install a set of electric barring drive mechanism additional in traction machine hand turning position, realizes auto-barring.The jiggering
Device is fixed with traction machine integrative installation technology, changes larger to traction machine, and mounting and adjusting slightly has inconvenience, while the barring gear is not
It is furnished with and traction machine power separating device, after jiggering operation terminates, when elevator normally runs, barring mechanism need to be dismantled temporarily, under
Carry out mounting and adjusting during secondary jiggering again, it is very inconvenient.

When motor 26 shuts down, braking prevents car slipping immediately again for brake 27.Jiggering terminates, and lift car reaches the nearest building of rescue
During layer, stop motor 26, while the brake 27 for decontroling traction machine 1 is braked, fixes car and implement rescue.
After jiggering rescue terminates, 24 power-off restoration of electromagnetism push rod, shift fork 21 rotationally clockwise, promote second turn
Pulling sleeve 23 on axle 14 is moved, and buffer spring 19 unclamps makes plane bearing 13 first return with pulling sleeve 23, in the strong of back-moving spring 15
Under power drives, driving gear 17 is departed from driven gear 11, if driving gear 17 does not depart from driven gear 11, control in time
System can be designed with the forward and reverse instantaneous inching function of automatic motor 26, make 26 slight forward and reverse crawl of motor, using chain
Bar drive gap makes gear complete to depart from, and illustrates that when 22 action of travel switch driving gear 17 and driven gear 11 have been completed point
From action, jiggering operation terminates.
The present embodiment is electric barring equipment advantageous embodiments, in the case where principle is essentially identical, is embodied as knot
It is various that structure is likely to change.For example when being applied to compared with large-tonnage traction machine 1, separately can configure in 5 outside output shaft end of drive sprocket
Hand turning wheel, using chain reduction power-saving function, carries hand-barring than former traction machine 1 more laborsaving.
And for example, first rotating shaft 10 and the second rotating shaft 14 are mounted directly using cabinet exterior hole, omit bearing block.It is various basic
Operation principle identical deforms, and is all visually embodiment of the present utility model.
Embodiment 2
With differing only in for embodiment 1, motor 26, decelerator 25, brake 27 and electromagnetism push rod 24 are arranged on machine
Outside case 28, while cancelling travel switch 22, but travel switch 29 and travel switch 30 are respectively provided with shift fork both sides, are passed through
The extreme position of shift fork is perceived, the engagement of driving gear and driven gear is detected.
Above scheme is electric barring equipment advantageous embodiments, and the electric barring equipment that this utility model is provided can
The electronic auto-barring that manual operation traction machine brake in machine room declutches in the case of spanner is realized, also can be with reference to being configured with traction
The elevator of machine remote brake release system, realizes the several functions such as Full-automatic remote and live remote control jiggering.
