Description
Technical field
The utility model relates to a kind of steel rope traction class elevator, belongs to the elevator safety technical field, particularly relates to a kind of safety detection device that disconnected strand broken lot occurs or is about to occur traction steel-cable that detects.
Background technology
Elevator safety protection system does not configure this type of broken strand of steel cable broken lot fender guard at present.Stipulate according to national special safety equipment specification TSG T7001-2009 " elevator supervision and inspection and periodical survey rule-traction and forcibly driving elevator ": as traction steel-cable occur that cage shape distortion, wire rope core are extruded, twisted together, part is flattened, bending or a disconnected burst phenomenon, should belong to the situation of scrapping, must in time change impaired steel rope.As in time not changing the above-mentioned steel rope of scrapping situation occurring, increase with the extent of damage, gently then cause elevator comfort variation or noise, heavy then cause oppressive event or damage other parts.
From present elevator technology present situation, elevator traction system adopts wire rope suspensioning to be still a direction of elevator Future Development, along with elevator speed is more and more faster, the car load-carrying is also increasing, it is a very crucial safety component that traction steel-cable is doomed, and the service condition that immediately detects traction steel-cable is a very important job.
For the detection of the traction steel-cable extent of damage, use the Special elevator steel wire rope fault finder on the industry at present, mainly adopt the Magnetic Flux Leakage Inspecting technology.This steel rope flow detector can accurately detect the disconnected stock market-circumstance condition of steel rope fault; but this fault finder belongs to the Special precision instrument; can't popularize and immediately steel rope be detected, can only use as a kind of checking tool of special project, not belong to the safety system parts of elevator configuration itself.
The utility model content
The purpose of this utility model is in order to provide a kind of cost low, simple in structure, can effectively to detect the safety detection device of broken strand of steel cable broken lot, can satisfying the demand that elevator detects safe wire cable.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of elevator dragging wire rope safety detection device, it is installed in mainframe machine beam or elevator traction sheave top between elevator traction sheave and the track adjusting wheel, be used for the elevator dragging wire rope service condition is carried out continuous detecting, disconnected burst of broken lot phenomenon appears in the main traction steel-cable that detects, for elevator operating troubles checking system provides the steel rope breakdown signal.
Furthermore, detecting device of the present utility model comprises: crust of the device; Be fixed on shake-up sheet and micro-switch on this crust of the device; And signal processing unit.
Furthermore, on two channel-section steels that detecting device shell of the present utility model is fixed under the machine bed and provides support for track adjusting wheel.
By technique scheme, advantage and the beneficial effect that the utlity model has are:
Principle of the present utility model is to design for the feature of steel rope abnormal phenomenon, can detect the abnormal condition such as steel rope serious distortion, steel rope broken lot, broken strand of steel cable and groove skipping of steel rope while, mainly can detect the steel rope strange phenomena before fully disconnected strand of steel rope, the elevator safety accident occurs in prevention.
The beneficial effect of the utility model device is to utilize steel rope the feature of disconnected strand broken lot to occur, detect the steel rope out-of-the way position with mechanical system, its manufacture craft is simple, cost is low, and safety is good, easily promotes, can satisfy the requirement that detects the broken strand of steel cable broken lot, and the utility model device easily cooperates with elevator structure, rationally utilizes the space, is convenient to dismounting.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in further detail, but the utility model is not limited in following embodiment.
See also shown in Fig. 1-3, elevator dragging wire rope safety detection device 50 of the present utility model is to be installed on the elevator main frame machine beam 40, adopt the mechanical detection mode, mainly be that the situation of disconnected strand of place's chain mark or the increase of broken lot place diameter can appear in steel rope when thigh or broken lot occurring breaking for traction steel-cable 30.When these steel rope out-of-the way positions processes configure the detecting device that is installed on the elevator, will touch the switch block on the detecting device, switching device will form electric signal, sends after treatment warning, thus prompting detects the steel rope abnormal condition.
A lot of broken strand of steel cables have a common ground when having an accident, anti-exactly pogo stick is bended, this dynamics is very large, in the time of disconnected burst definitely the chain mark situation can appear first, it is serious that the steel rope that exposes slowly becomes, then the exposed steel wire rope snarls obstacle through rope sheave or anti-pogo stick, causes and stops terraced accident thereby pull whole strand steel wire rope.
According to above-mentioned situation, mainframe machine beam 40 or the elevator traction sheave 10 tops place of safety detection device 50 of the present utility model between elevator traction sheave 10 and guide wheel of elevator 20 installs safe wire cable detecting device 50 additional, and the device detection part mainly reaches relevant auxiliary circuit (signal processing unit) by micro-switch 52, shake-up sheet with 53 and forms.
When damage of steel cable begins to occur steel rope fault, the fracture of wire degree can increase with number of run become serious, steel rope occurs at last and exposes phenomenon, and steel rope Rose seriously locates through touching sheet 53 and triggering micro-switch 52 and move, and device will be reported to the police or bright light; Simultaneously, actuating signal can be inputted elevator control mainboard, and the input of elevator basis signal judges that abnormal failure appears in steel rope, and handles accordingly according to the fault predetermine level.
The related elevator dragging wire rope detecting device of the utility model has " normally " and " maintenance " two kinds of mode of operations to select.When selecting " normally " mode of operation, detecting device can be transferred to elevator control mainboard to signal, receive the abnormal signal of detecting device and satisfy corresponding failure level setting condition such as elevator-mainboard, elevator-mainboard will send nearest station flat bed and stop terraced instruction or do not process a record trouble; When selecting " maintenance " mode of operation, detecting device can not be transferred to elevator control mainboard to signal, only can send at detecting device itself and report to the police or bright light, makes things convenient for the repair and maintenance personnel to the care work of elevator wire rope.
This device construction is simple and with low cost, can become the constituent elements of elevator safety protection system, and disconnected burst of broken lot phenomenon appears in the immediately monitoring steel rope.
Embodiment one
In Fig. 1, safety detection device 50 of the present utility model comprises the crust of the device 50 on two channel-section steels that are fixed under the machine bed and provide support for guide wheel of elevator 20, the shake-up sheet 53 that is installed on this crust of the device 51 and can swings up and down, be installed on this crust of the device 50 and can be touched the micro-switch 52 that sheet 53 touches by this, such as the exposed steel wire 31 that traction steel-cable 30 exists above, then exposed steel wire 31 just can touch sheet 53 by on the go.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, therefore every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
