Description
Technical field
The present invention relates to a kind of elevator safety monitoring device, particularly to a kind of elevator rope end fracture monitoring dress
Put.
Background technology
For being more to pay close attention to up-downgoing hypervelocity in the detection device industry that elevator actual time safety runs, exceed
The detection of extreme position, after detecting correlation values, carries out switch dynamic in real time to traction machine and limiter of speed etc.
Making, thus ensure the safe operation of elevator, the most in the world, this is universal effective detection elevator peace
The device of row for the national games, but, for the protection of elevator rope break, then main guarantor after generation rope-broken accident
Protecting, after the most well-known disconnected rope, then detect elevator and react, after disconnected rope, speed is unstable,
Car falls and causes limiter of speed safety tongs action etc., it is clear that this protection is a lack of meeting property in advance.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 improve further.
Summary of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art, it is provided that a kind of elevator rope end fracture monitoring dress
Putting, this device is when single elevator wire rope there are disconnected rope tendency, it is possible to warning in advance or stopping elevator fortune
OK, its simple in construction, manufacturing easy for installation, and it is little to take up room.
For achieving the above object, the present invention adopts the following technical scheme that.
A kind of elevator rope end break monitoring device, including multiple fag ends and travel switch, travel switch is located at peace
On dress plate, described installing plate being hinged with fork, fork is connected with installing plate by one end, and fork side is supported
It is connected on the Self-resetting pressure head of travel switch, and by being positioned at the snap lock locking mechanism locking of fork opposite side；
Connecting on fork has drag-line, drag-line to be fixed with fork by one end, and the other end of drag-line is provided with by fag end
Cross-perforating sequentially passes through multiple fag end, and stay wire end and the fag end being positioned at far-end are fixed, and drag-line passes through two ends
Fix and tighten.
Use the present invention of preceding solution, the control switching signal of travel switch run as elevator
Signal, when the Self-resetting pressure head of travel switch is oppressed by fork, elevator is properly functioning；When travel switch
When Self-resetting pressure head resets, elevator is out of service.Fork passes through snap lock locking mechanism locking, and connection is drawn
Rope, drag-line passes multiple fag ends, and stay wire end and the fag end being positioned at far-end are fixed, and drag-line is fixed by two ends
Tighten.With when arbitrary fag end stretching or fracture defect occurs at traction steel-cable, fag end is made at counterbalance spring
Use lower movement, after making it overcome the elastic force of the elastic locking of compressing by drag-line pulling fork, in release travel
The direction of the Self-resetting pressure head of switch swings.When fag end displacement reaches setting value, swing displacement and meet certainly
Reset pressure head reset shift value, Self-resetting pressure head resets, and corresponding elevator is out of service.Therefore, the present invention
Monitoring device just can produce effect, as long as but preseting length occurs in steel wire rope after being not required to fag end fracture by the time
During stretcher strain amount, or when arbitrary steel wire rope there are disconnected rope tendency, elevator is made to stop transport by force.And knot
Structure is simple, it is easy for installation to manufacture, and it is little to take up room.The switching signal of travel switch is being transported as elevator
The alarm signal of row, when arbitrary steel wire rope there are disconnected rope tendency, can and alarm.
Preferably, described snap lock locking mechanism includes that blocking element, blocking element installing are provided with on a mounting board
Installing hole in, blocking element has the part of extended installing hole, and installing hole rear end is screwed with adjustment plug screw,
Adjust and be provided with compression spring between plug screw and blocking element.To simplify lockable mechanism structure, further ensure that knot
Structure is simple, latch functions is 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.Further ensure that simple in construction, and under fag end displacement effect, unlock quick.And steel ball can be direct
Commercially, the convenience manufacturing efficiency with maintenance replacing is improved.
It is further preferred that described blocking element and installing hole are all in ledge structure, blocking element leading portion diameter
Less than back segment, blocking element front end is frustum structure；Described fork respective side is formed with guiding surface.Enter one
Step guarantees that simple in construction, latch functions are reliable, and unlocks quick.
The present invention 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 take up room
Little.
