Description
Technical field
The utility model relates to elevator protection device, especially relates to the anti-accidental movement device of elevator cabin flat level.
Background technology
Modern city rhythm is constantly accelerated, and living standard is more and more higher, and traffic is also more and more convenient, and high-rise residential building, office building are rised sheer from level ground in succession, and elevator also becomes the indispensable part of people's daily life.Elevator is the same with other maneuver classes products, and Long-Time Service is all its function of loss to break down.Elevator arrives after the floor car door of specifying opens, and it is one of common important safety fault of elevator that car continues to rise or decline, and causes personnel to be blocked by elevator dead event of suffocating thus happening occasionally.Therefore, how preventing car door from opening rear car and continue to rise or decline, is the problem that those skilled in the art pay close attention to always.
Summary of the invention
The utility model object is to provide a kind of elevator cabin flat level anti-accidental movement device.
For achieving the above object, the utility model takes following technical proposals:
The anti-accidental movement device of elevator cabin flat level described in the utility model, comprises and is fixed on hook mount pad on car back timber and electromagnetic draw bar mount pad vertically upward; Described electromagnetic draw bar forms by electromagnet with by the pull bar of its driving, and described hook is inverted L-shaped hook; Housing and the electromagnetic draw bar mount pad of described electromagnet are hinged, and armstand and the described hook mount pad of described inverted L-shaped hook are hinged; The upper end that the upper end of described pull bar and inverted L-shaped link up with armstand is hinged; The transverse arm of described inverted L-shaped hook is hinged with riser, the edge described riser being positioned at described armstand side offers gap, touch switch is provided with in described gap, described touch switch is series in the safety return circuit of elevator, for cutting off actuator electrical source circuit, be fixed with the braking link plate linked up with transverse arm with inverted L-shaped and match in the side being positioned at every layer of elevator rail.
Described hook mount pad is fixed with unhook detector switch.
The utility model advantage is to realize to stop elevator when arriving the floor of specifying, and car door link plate opens the phenomenon that rear car continues to rise or decline, and reaches the security purpose that available protecting takes elevator personnel.

Fig. 3 is the structural representation of braking link plate described in the utility model.
Detailed description of the invention
As Figure 1-3, the anti-accidental movement device of elevator cabin flat level described in the utility model, comprises and is fixed on hook mount pad 2 on car back timber 1 and electromagnetic draw bar mount pad 3 vertically upward; Described electromagnetic draw bar forms by electromagnet 4 with by the pull bar 5 of its driving, and described hook is inverted L-shaped hook; Housing and the electromagnetic draw bar mount pad 3 of described electromagnet 4 are hinged, and the armstand 6 of described inverted L-shaped hook is hinged with described hook mount pad 2; The upper end that the upper end of described pull bar 5 and described inverted L-shaped link up with armstand 6 is hinged, the transverse arm 7 of inverted L-shaped hook is hinged with riser 8, the edge described riser 8 being positioned at inverted L-shaped hook armstand 6 side offers gap, touch switch 9 is provided with in described gap, described touch switch 9 is series in the safety return circuit of elevator, for cutting off actuator electrical source circuit; The braking link plate 11 linked up with transverse arm 7 with described inverted L-shaped and match is fixed with in the side being positioned at every layer of elevator rail 10; Judge whether inverted L-shaped hook is in unhook state for convenience, hook mount pad 2 is fixed with the unhook detector switch 12 linked up with armstand 6 with inverted L-shaped and coordinate.
Utility model works principle is summarized as follows:
When elevator is in floor door district after stopping brake, the power-off of described electromagnet 4, under the thrust being set in the pressure spring 13 on described pull bar 5, the transverse arm 7 that described inverted L-shaped is linked up with is shifted onto in the lockhole of the braking link plate 11 being fixed on elevator rail 10 side, if now lift car meets accident movement, when car moves a certain distance, described riser 8 will strike braking link plate 11, the touch switch 9 be arranged in described gap is touched and safety return circuit and elevator drive power supply is disconnected, and now elevator is in faulty condition and can not restarts; If car continues accidental movement, the transverse arm 7 of inverted L-shaped hook will enter locking state with braking link plate 11, and reach and avoid car to cause casualties the generation of accident because of accidental movement, now elevator can not be restarted, and must be resetted by professional.
When elevator orderly shutdown and car zero accident moves generation, when elevator starts again, by the normal work schedule of elevator, described electromagnet 4 obtains electric, under the effect of electromagnetic force, in the lockhole of the transverse arm 7 self-retention link plate 11 that the elastic force that pull bar 5 overcomes described pressure spring 13 links up with inverted L-shaped, pull-out unlocks, the armstand 6 that now inverted L-shaped is linked up with is touched unhook detector switch 12(unhook detector switch 12 and can be connected in elevator internal contracting brake stroke detection loop, be used for detecting car and whether depart from locking state), to judge that car exits lock-out state, and make elevator enter running state.
When elevator causes inverted L-shaped to be linked up with entering latched position due to other fault in operational process and within the scope of Bu Men district, car can not can stop in time due to inertia reason, the transverse arm 7 linked up with for avoiding inverted L-shaped clashes into the generation that braking link plate 11 causes elevator damage and personnel casualty accidents, as shown in Figure 3, brake the upper of link plate 11, the hypotenuse 14 with certain angle is arranged in lower edge, like this, when the transverse arm 7 of inverted L-shaped hook clashes into braking link plate 11, due to the reason of braking link plate 11 hypotenuse 14, braking link plate 11 is moved outside cage guide 10 slip over from braking link plate 11 side, avoid inverted L-shaped hook frontal impact braking link plate 11 and cause damage.After inverted L-shaped hook slips over from braking link plate 11 side, under pressure spring 13 acts on, inverted L-shaped hook recovers home position rapidly.
