Description
Technical field
The utility model relates to the unexpected fender guard of a kind of elevator.
Background technology
Elevator is generally tractive driving, and by steel wire hang on the traction sheave, traction sheave drives by motor direct-drive or through speed reduction gearing car.Under normal circumstances, when wanting elevator to stop, elevator receives danger signal, brake, and traction sheave is not turned.Car is motionless at level position, namely stops.The vertical distance deviation of car sill and landing sill keeps within the specific limits.Elevator is typical electromechanical integrated product, and mechanical part and electric elements all participate in work all the time.Elevator runs needs certain condition, and when there being following situation to occur, elevator likely meets accident movement, thus generation shearing accident.
1, when apparatus for controlling elevator lost efficacy (accident as door lock lost efficacy), at this moment elevator just likely opens and to run, and elevator meets accident movement, and the danger of shearing occurs;
2, when the machinery of elevator, driving system go wrong (as drg scarce capacity or inefficacy), at this moment elevator should stop running, because driving system has problem elevator not stop, there is the danger of shearing at this moment elevator generation elevator accidental movement;
3, when elevator stops, when the cargo weight acute variation of loading, when the friction force of elevator is destroyed, elevator likely meets accident movement, and the danger of shearing occurs;
Fender guard great majority on current market utilize the device of similar velocity limiter and safety tongs to realize.Namely, during elevator accidental movement, elevator moves to have speed detection unit to detect.And speed reaches certain technical requirements.This device is the ability trigger action when elevator meets accident mobile only, and add action delay, by the time during this device action, elevator has met accident and moved, and at this moment elevator is not at level position.This fender guard has very high technical requirements to detecting element, control circuit, power element.Installation, debugging, maintaining are not easily.Particularly the maintaining in later stage is not in place, and repacking is put would not action, or the requirement of out of reach protection after action.Crucial this be elevator meet accident mobile after passive protection.At this moment likely there occurs shearing accident.Passive protection be when something unexpected happened mobile just protect, this just can not prevent the generation of accidental movement situation.Prevent the generation of accidental movement situation, key is in prevention, namely makes fender guard action in advance, and namely elevator changes fender guard just action in advance when not having accidental movement.Become passive protection into initiatively protection.Do not affect the normal function of elevator simultaneously.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of elevator unexpected fender guard.
The utility model solves the technical scheme that its technical matters adopts: the unexpected fender guard of a kind of elevator, comprise lift car, cage guide and apparatus for controlling elevator, the bottom of described car arranges base, stop bar, electromagnet and reset switch, described stop bar, electromagnet and reset switch are arranged on base, described magnet control stop bar moves horizontally on base, described reset switch is arranged on the base of stop bar side, and described reset switch is positioned in the path of motion of stop bar;
Described guide rail being provided with stop frame, described stop frame being provided with the location switch for coordinating with stop bar and the rod aperture for clamping stop bar;
Described fender guard also comprises fender guard control system, and described fender guard control system forms Electricity Federation with apparatus for controlling elevator, electromagnet, reset switch and location switch respectively.
Further, described location switch is arranged in rod aperture.
Further, described location switch is arranged on the outside face of rod aperture.
The beneficial effects of the utility model are: fender guard of the present utility model is simple and practical, and Installation and Debugging are convenient.Become passive protection for initiatively protection, stop at elevator, meet accident movement when with regard to action in advance.Do not need elevator to move just to protect afterwards, can prevent trouble before it happens.

Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1; the unexpected fender guard of a kind of elevator; comprise lift car 1, cage guide 2 and apparatus for controlling elevator; the bottom of car 1 arranges base, stop bar 3, electromagnet 4 and reset switch 5; stop bar 3, electromagnet 4 and reset switch 5 are arranged on base; electromagnet 4 controls stop bar 3 and moves horizontally on base, and reset switch 5 is arranged on the base of stop bar 3 side, and reset switch 5 is positioned in the path of motion of stop bar 3.
Guide rail 2 being provided with stop frame 6, the guide rail 2 of each level position of floor is provided with stop frame 6, stop frame 6 being provided with the location switch 7 for coordinating with stop bar 3 and the rod aperture for clamping stop bar 3; For the accuracy making raising stop bar 3 and location switch 7 coordinate, location switch 7 is arranged in rod aperture.Certainly according to actual needs, location switch also can be arranged on the enterprising enforcement use of outside face of rod aperture.
Fender guard of the present utility model also comprises fender guard control system, and fender guard control system forms Electricity Federation with apparatus for controlling elevator, electromagnet 4, reset switch 5 and location switch 7 respectively.
When elevator stops; after fender guard control system receives district's signal peace layer signal, brake operation signal; control electromagnet 4 action; electromagnet 4 works and drives stop bar 3 protruding; inside the rod aperture being inserted into the stop frame 6 be fixed on guide rail 2; as shown in Figure 2; thus the location switch 7 in triggering rod aperture; send a signal to fender guard control system; represent fender guard action; then fender guard control system sends a signal and returns to apparatus for controlling elevator, does not allow elevator to run.
When elevator will run; after fender guard control system receives elevator run signal, door-closing in-place signal gate; electromagnet 4 discharges; stop bar 3 is retracted, and when being retracted into assigned address, triggers stop bar 3 reset switch 5; send a signal to fender guard control system; represent that fender guard resets, fender guard control system sends a signal to apparatus for controlling elevator, allows elevator to run.Only have the elevator when elevator meets condition of service to run, otherwise elevator is then locked in level position can not move.Thus elevator can not move, and plays a protective role.Prevent elevator generation shearing accident.
Fender guard of the present utility model can play a protective role.Do not affect elevator normal function simultaneously.After apparatus of the present invention action, even if that something unexpected happened is mobile for elevator, rely on stop bar 3 to be inserted in stop frame 6, elevator still stops at level position, and leveling error is in the scope that standard allows.Thus ensure the safety of passenger and goods.
The control setup of the pattern similar to the unexpected fender guard of this practicality or layout, similar structure or layout, fender guard or similar structure or mode are all within the protection domain of this patent.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
