Description
Technical field
This utility model relates to a kind of elevator safety monitoring device, particularly to a kind of elevator rope end break monitoring device.
Background technology
For being more to pay close attention to up-downgoing hypervelocity in the detection device industry that elevator actual time safety runs, go beyond the limit of position
The detection put, after detecting correlation values, carries out switch motion to traction machine and limiter of speed etc. in real time, thus ensures elevator
Safe operation, the most in the world, this is the universal effective device detecting elevator safety operation, but, elevator is broken
The protection of rope, then mainly there is the protection after rope-broken accident, after the most well-known disconnected rope, then elevator is detected and
Reaction, after disconnected rope, speed is unstable, and car falls and causes limiter of speed safety tongs action etc., it is clear that this protection is a lack of in advance
Meeting property.And this is also monitored without specific requirement by GB7588-2003 in advance.At present, although occur in that some disconnected rope monitoring dresses
The scheme put, but these monitoring devices all exist, and structure is complicated, manufacturing cost is high, take up room big deficiency.For this reason, it may be necessary to enter
One step is improved.
Summary of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art, it is provided that a kind of elevator rope end break monitoring device,
This device is when single elevator wire rope there are disconnected rope tendency, it is possible to warning in advance or stopping elevator running, its simple in construction,
Manufacture easy for installation, and it is little to take up room.
For achieving the above object, this utility model adopts the following technical scheme that.
A kind of elevator rope end break monitoring device, including multiple fag ends and travel switch, travel switch sets on a mounting board,
Being hinged with fork on described installing plate, fork is connected with installing plate by one end, and fork side is connected to the runback of travel switch
On the pressure head of position, and by being positioned at the snap lock locking mechanism locking of fork opposite side；On fork connect have drag-line, drag-line by one end with
Fork is fixed, and the cross-perforating that the other end of drag-line is provided with by fag end sequentially passes through multiple fag end, stay wire end be positioned at
The fag end of far-end is fixed, and drag-line is tightened by two ends are fixing.
Use this utility model of preceding solution, the control letter switching signal of travel switch run as elevator
Number, when the Self-resetting pressure head of travel switch is oppressed by fork, elevator is properly functioning；When the Self-resetting pressure head of travel switch resets
Time, elevator is out of service.Fork passes through snap lock locking mechanism locking, and connection has drag-line, and drag-line passes multiple fag ends, drag-line end
End is fixed with the fag end being positioned at far-end, and drag-line is tightened by two ends are fixing.Stretching to occur at arbitrary fag end at traction steel-cable
Or during fracture defect, fag end moves under counterbalance spring effect, pull fork by drag-line and make it overcome the elastic locking of compressing
After elastic force, in release travel, the direction of the Self-resetting pressure head of switch swings.When fag end displacement reaches setting value, swing position
Shifting meets Self-resetting pressure head reset shift value, and Self-resetting pressure head resets, and corresponding elevator is out of service.Therefore, of the present utility model
Monitoring device just can produce effect, as long as but the stretcher strain amount of preseting length occurs in steel wire rope after being not required to fag end fracture by the time
Time, or when arbitrary steel wire rope there are disconnected rope tendency, make elevator stop transport by force.And simple in construction, manufacture are easy for installation, and
Take up room little.In the alarm signal that the switching signal of travel switch is run as elevator, there are disconnected at arbitrary steel wire rope
Rope tendency time, can and alarm.
Preferably, described snap lock locking mechanism includes blocking element, and blocking element installs the installation being provided with on a mounting board
In hole, blocking element has the part of extended installing hole, and installing hole rear end is screwed with adjustment plug screw, adjusts plug screw and locking structure
Compression spring it is provided with between part.To simplify lockable mechanism structure, further ensure that simple in construction, latch functions are reliable.
It is further preferred that described blocking element is steel ball, described installing hole front end is outer little interior big taper hole structure.Enter
One step guarantees simple in construction, and under fag end displacement effect, unlocks quick.And steel ball the most commercially can improve system
Make efficiency and the convenience of maintenance replacing.
It is further preferred that described blocking element and installing hole are all in ledge structure, after blocking element leading portion diameter is less than
Section, blocking element front end is frustum structure；Described fork respective side is formed with guiding surface.Further ensure that simple in construction, lock
Only function is reliable, and unlocks quick.
This utility model compared with prior art provides the benefit that, there are disconnected rope tendency at single elevator wire rope
Time, it is possible to warning in advance or stop elevator and run, its simple in construction, manufacture easy for installation, and it is little to take up room.
