Description
Technical field
The present invention relates to a kind of elevator safety monitoring device, in particular to a kind of elevator rope end break monitoring device.
Background technique
For being more concern uplink and downlink hypervelocity in the detection device industry of elevator actual time safety operation, position is gone beyond the limit of
The detection set carries out switch motion to traction machine and limiter of speed etc. in real time, to guarantee elevator after detecting correlation values
Safe operation, at home in the world, this is the device of universal effective detection elevator safety operation, still, disconnected for elevator
The protection of rope, then the mainly protection after rope-broken accident occurs, i.e., after well-known disconnected rope, then to elevator carry out detection and
Reaction, after disconnected rope, speed is unstable, and carriage, which is fallen, leads to limiter of speed safety tongs movement etc., it is clear that this protection is a lack of earlier
Meeting property.And GB7588-2003 is also to this earlier monitoring without specific requirement.Although currently, there are some disconnected rope monitoring dresses
The scheme set, but the deficiency that these monitoring devices all exist that structure is complicated, manufacturing cost is high, occupied space is big.For this reason, it may be necessary into
One step is improved.
Summary of the invention
The purpose of the present invention is to the deficiencies in the prior art, provide a kind of elevator rope end break monitoring device, the dress
It sets when single elevator wire rope is inclined to there are disconnected rope, warning in advance or elevator operation can be stopped, structure is simple, manufacture
It is easy for installation, and occupy little space.
To achieve the above object, the present invention adopts the following technical scheme that.
A kind of elevator rope end break monitoring device, including multiple rope ends and travel switch, travel switch are set on a mounting board,
Swing rod is hinged on the mounting plate, swing rod is connect by one end with mounting plate, and swing rod side is connected to the runback of travel switch
On the pressure head of position, and the elastic lockable mechanism locking by being located at the swing rod other side；Be connected with drag-line on swing rod, drag-line by one end with
Swing rod is fixed, and the other end of drag-line sequentially passes through multiple rope ends by the cross-perforating that rope end is equipped with, stay wire end be located at
The rope end of distal end is fixed, and drag-line is tightened by both ends fixation.
Using the present invention of preceding solution, the control signal that the switching signal of travel switch is run as elevator,
When the Self-resetting pressure head of travel switch is oppressed by swing rod, elevator is operated normally；When the Self-resetting pressure head of travel switch resets,
Elevator is out of service.Swing rod passes through elastic lockable mechanism locking, and is connected with drag-line, and drag-line passes through multiple rope ends, stay wire end
It is fixed with the rope end for being located at distal end, drag-line is tightened by both ends fixation.To occur stretching in traction steel-cable in any rope end or
When fracture defect, rope end moves under counterbalance spring effect, and pulling swing rod by drag-line makes it overcome the bullet of the elastic locking of compressing
Property power after, in release travel switch Self-resetting pressure head direction swing.When rope end displacement reaches setting value, displacement is swung
Meet Self-resetting pressure head and reset shift value, Self-resetting pressure head resets, and corresponding elevator is out of service.Therefore, monitoring of the invention dress
Set be not required to until rope end fracture after can just generate effect, as long as but wirerope occur set length stretcher strain amount when, or
When any wirerope is inclined to there are disconnected rope, elevator is set to stop transport by force at once.And structure is simple, manufacture is easy for installation, and occupies
Space is small.In the alarm signal for running the switching signal of travel switch as elevator, in any wirerope, there are disconnected ropes to incline
Xiang Shi, can and alarm.
Preferably, the elastic lockable mechanism includes blocking element, and blocking element installs the installation being equipped on a mounting board
In hole, blocking element has the part of extended mounting hole, and mounting hole rear end is screwed with adjustment plug screw, adjustment plug screw and locking structure
Compressed spring is equipped between part.To simplify lockable mechanism structure, further ensure that structure is simple, latch functions are reliable.
It is further preferred that the blocking element is steel ball, the mounting hole front end is in outer small interior big taper hole structure.Into
One step ensures that structure is simple, and under rope end displacement effect, unlock is quick.And steel ball directly commercially can improve system
Make the convenience of efficiency and maintenance replacement.
It is further preferred that the blocking element and mounting hole are in step structure, after blocking element leading portion diameter is less than
Section, blocking element front end are in frustum structure；The swing rod respective side is formed with guiding surface.Further ensure that structure is simple, locks
Only function is reliable, and unlocks quick.
Compared with the prior art, the invention has the advantages that when single elevator wire rope is inclined to there are disconnected rope, energy
Enough warning in advance stop elevator operation, and structure is simple, manufacture is easy for installation, and occupies little space.
