Abstract
The invention discloses a device for preventing an elevator cage from abnormally moving. The device comprises a braking mechanism installed on a cage large beam, a reset mechanism arranged at one end of the braking mechanism, and an electrical detecting mechanism. The braking mechanism comprises a shell. A U-shaped action jaw is arranged on one lateral side of the shell. An elevator T-shaped guide rail is located in the U-shaped action jaw. Electromagnets and brake pads are symmetrically arranged on the two sides of the U-shaped action jaw. The brake pads are installed at the ends of the electromagnets and are stretched out and drawn back under the control of the electromagnets so as to clamp and release the elevator T-shaped guide rail. The electrical detecting mechanism comprises a magnetic strip installed on the elevator T-shaped guide rail and a magnetic strip sensor opposite to the magnetic strip. The magnetic strip sensor is installed on the side, with the U-shaped action jaw, of the shell. By the adoption of the mechanical and electrical integration design, the device has the advantages of being capable of conducting detection and recognition automatically, high in response speed and short in braking length.
Description
Technical field
The present invention relates to a kind of lift car accessory, relate in particular to a kind of abnormal mobile device of lift car that prevents.
Background technology
At present, Chinese having become has the country that elevator is maximum in the world, has 2,400,000 elevators every day in running, and average every people more than 500 just has an elevator, and is increasing with 15% speed every year.The increase of elevator quantity, repair and maintenance work capacity is increased, many elevators are because repair and maintenance work is not in place, or lift facility is aging etc., and reason causes the safety misadventure of elevator to increase, wherein, in the situation of opening the door, car moves caused safety misadventure and frequently occurs, under elevator door opening, traditional elevator has two kinds of modes to prevent that elevator from moving, the one, main frame drg, but this device acts on position of host machine, can not prevent that the car that skid or because of this drg fault own cause of steel rope on traction sheave from moving; The 2nd, car safety because the many employings of car safety are gradual, and must cause its action by velocity limiter in the situation that exceeding command speed, and therefore braking distance is excessive, far beyond the safe allowed band in door district.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of abnormal mobile device of lift car that prevents is provided, by adopting sensor detecting and magnet switching mode, can realize door-opened elevator region car when extremely mobile, lift car is locked on guide rail.
For achieving the above object, the present invention proposes following technical scheme:
A kind of abnormal mobile device of lift car that prevents, it is characterized in that: comprise the drag mechanism being arranged on car crossbeam, be located at Bringing-back mechanism and the electric testing agency of described drag mechanism end, 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 under the control of electromagnet, stretch out and retract to clamp and unclamp T-shaped guide rail, described electric testing agency comprises the magnetic stripe that is arranged on elevator T type guide rail and the magnetic stripe sensor relative with described magnetic stripe, described magnetic stripe installation of sensors has a side of U-shaped action jaw at housing.
Institute's rheme magnetic stripe sensor connects elevator control cabinet.
In described magnetic stripe sensor, be preset with the departure distance of 2 ~ 5cm.
Described drag mechanism, Bringing-back mechanism and electric testing agency all connect UPS electric power system.
Compared with prior art, what the present invention disclosed prevents the abnormal mobile device of lift car, utilize sensor detecting that car is moved up and down to restriction within the specific limits at door open period, and quick and precisely judge car position, in the time that operating instruction is not sent with apparatus for controlling elevator in the position of car under door opening, 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, automatically identification, fast response time, the advantage that stopping distance is short, prevent that shearing from appearring in elevator, the potential safety hazards such as extruding, thereby passenger safety is seen in protection.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention prevents the abnormal mobile device of lift car.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present invention, the technical scheme of the embodiment of the present invention is carried out to clear, complete description.
As shown in Figure 1, disclosed a kind of abnormal mobile device of lift car that prevents, specifically comprises drag mechanism 1, Bringing-back mechanism 2 and electric testing agency 3, and described drag mechanism 1, Bringing-back mechanism 2 and electric 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 one sides are provided with U-shaped action jaw 5, elevator T type guide rail 10 is placed in described U-shaped action jaw 5, in described shell 4, centered by U-shaped action jaw 5, be arranged with electromagnet 6, described electromagnet 6 ends are 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 and clamp T-shaped guide rail, under the control of electromagnet 6, retract and unclamp T-shaped guide rail 10 simultaneously.
Described Bringing-back mechanism 2 is reset button, and it is arranged on drag mechanism 1 end, connects described electromagnet 6, in the time of 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 shell 4 and is provided with a side of 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 in the time of operation contactless switch in control housing and the equal triggerless of braking contactor, magnetic stripe sensor 9 is worked, described magnetic stripe sensor 9 also connects electromagnet 6, to set out, electromagnet 6 is worked, in described magnetic stripe sensor 9, be preset with the departure distance of 2 ~ 5cm simultaneously, in the time exceeding default departure distance, magnetic stripe sensor 9 triggers electromagnet 6, make brake facing 7 stretch out to clamp T-shaped guide rail 10.
A kind of abnormal mobile device of lift car that prevents 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, detect control box interior operation contactless switch and braking contactor simultaneously and whether produce energizing signal, if there is no energizing signal, and magnetic stripe sensor 9 is once detect that car displacement exceedes 5cm, trigger electromagnet 6 brake facing is stretched out to clamp T-shaped guide rail 10, thereby prevented the situation that car falls.，
