Description
Technical field
The utility model relates to a kind of lift car accessory, particularly relates to a kind of device preventing the abnormal movement of lift car.
Background technology
At present, Chinese having become has the maximum country of elevator in the world, and have 2,400,000 elevators every day in running, on average every people more than 500 just has an elevator, and is increasing with the speed of 15% every year.The increase of elevator quantity, repair and maintenance work capacity is increased, many elevators due to repair and maintenance work not in place, or lift facility is aging etc., and reason causes the safety misadventure of elevator to increase, wherein, in enabling situation, car moves caused safety misadventure and frequently occurs, under elevator door opening, traditional elevator has two kinds of modes to prevent elevator from moving, one is main frame drg, but this device acts on position of host machine, steel rope skidding on the traction sheave can not be prevented or the car that causes because of the fault of this drg own moves; Two is car safeties, and because the many employings of car safety are gradual, and must cause its action when exceeding command speed by velocity limiter, therefore braking distance is excessive, far beyond the safe allowed band in door district.
Utility model content
The purpose of this utility model is the defect overcoming prior art, a kind of device preventing the abnormal movement of lift car is provided, by adopting sensor detecting and magnet switching mode, can realize door-opened elevator region car abnormal mobile time, lift car is locked on guide rail.
For achieving the above object, the utility model proposes following technical scheme:
A kind of device preventing the abnormal movement of lift car, it is characterized in that: comprise the drag mechanism be arranged on car crossbeam, be located at the Bringing-back mechanism of described drag mechanism end and electric testing agency, described drag mechanism comprises housing, described housing one side is provided with U-shaped action jaw, elevator T type guide rail is positioned at described U-shaped action jaw, described U-shaped action jaw bilateral symmetry is provided with electromagnet and brake facing, described brake facing is arranged on electromagnet end, and stretch out under the control of electromagnet and retract with clamping and unclamp T-shaped guide rail, described electric testing agency comprises and is arranged on magnetic stripe on elevator T type guide rail and the magnetic stripe sensor relative with described magnetic stripe, described magnetic stripe sensor is arranged on the side that housing has U-shaped action jaw.
Described magnetic stripe sensor connects elevator control cabinet.
The departure distance of 2 ~ 5cm is preset with in described magnetic stripe sensor.
Described drag mechanism, Bringing-back mechanism and electrically testing agency all connect UPS electric power system.
Compared with prior art, the device preventing the abnormal movement of lift car of the utility model announcement, utilize sensor detecting that car is moved up and down restriction within the specific limits at door open period, and quick and precisely judge car position, when the position of car is under door opening and when apparatus for controlling elevator does not send operating instruction, once sensor detects the improper movement of car, trigger action relay ejects brake facing, car is locked on guide rail, it adopts Electromechanical Design, possesses automatic detection, automatic identification, fast response time, the advantage that stopping distance is short, prevent elevator from occurring shearing, the potential safety hazards such as extruding, thus passenger safety is seen in protection.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model prevents the device of the abnormal movement of lift car.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical scheme of the utility model embodiment.
As shown in Figure 1, a kind of device preventing the abnormal movement of lift car that the utility model discloses, specifically comprises drag mechanism 1, Bringing-back mechanism 2 and electrically testing agency 3, and described drag mechanism 1, Bringing-back mechanism 2 and electrically testing agency 3 all connect UPS electric power system.
Particularly, described drag mechanism 1 is arranged on car crossbeam, it comprises shell 4, described shell 4 side is provided with U-shaped action jaw 5, elevator T type guide rail 10 is placed in described U-shaped action jaw 5, centered by U-shaped action jaw 5, electromagnet 6 is arranged with in described shell 4, described electromagnet 6 end is provided with brake facing 7, described brake facing 7 is positioned at elevator T type guide rail 10 both sides, and under the control of electromagnet 6, stretch out the T-shaped guide rail of clamping, retract under the control of electromagnet 6 simultaneously and unclamp T-shaped guide rail 10.
Described Bringing-back mechanism 2 is reset button, and it is arranged on drag mechanism 1 end, connects described electromagnet 6, when needs releasing of brake sheet 7, manually presses described Bringing-back mechanism 2, makes electromagnet 6 power-off, thus releasing of brake sheet 7.
Described electric testing agency 3 comprises magnetic stripe 8 and magnetic stripe sensor 9, described magnetic stripe 8 is arranged on elevator T type guide rail 10, described magnetic stripe sensor 9 is arranged on the side that shell 4 is provided with U-shaped action jaw 5, and described magnetic stripe sensor 9 is oppositely arranged with described magnetic stripe 8, described magnetic stripe sensor 9 connects elevator top control housing, and when running contactless switch and the equal triggerless of braking contactor in control housing, magnetic stripe sensor 9 works, described magnetic stripe sensor 9 also connects electromagnet 6, work to go out solenoid 6, be preset with the departure distance of 2 ~ 5cm in described magnetic stripe sensor 9 simultaneously, when exceeding default departure distance, magnetic stripe sensor 9 trigger electromagnet 6, brake facing 7 is made to stretch out to clamp T-shaped guide rail 10.
A kind of device preventing the abnormal movement of lift car that this practical information discloses, its principle of work is: after elevator arrival floor opens the door, this device is started working, now magnetic stripe sensor 9 starts to detect car position, in detection control case, whether operation contactless switch and braking contactor produce energizing signal simultaneously, if there is no energizing signal, and magnetic stripe sensor 9 is once detect that car displacement is more than 5cm, brake facing stretches out to clamp T-shaped guide rail 10 by trigger electromagnet 6, thus the situation preventing car to fall.，
When after trouble shooting, manually press reset button, make electromagnet 6 dead electricity, thus retraction brake facing 7, remove the clamping to T-shaped guide rail 10.
Technology contents of the present utility model and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present invention and announcement; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
