The steel wire rope that top connects, the other end of steel wire rope walks around hoist engine and is connected with counterweight, and the top connection of described car has
Seat belt, the top of described hoistway is provided with the coiler for folding and unfolding seat belt, also includes when elevator stops and described car
The doorframe of engaging, is provided with handrail in doorframe.
Wherein, described doorframe includes arranging the top of two risers being symmetrical set and two ends and two risers even
The transverse slat connect.
Wherein, the medial surface of described riser offers the groove of the length direction setting along riser, and described handrail is by arranging
Cylinder composition in groove, cylindrical height is equal to the height of riser.
Wherein, described car is provided with gate, and described doorframe is provided with safety door, and the top of car is provided with door lifter,
Door lifter is connected with gate by drive mechanism, and gate and safety door linkage are arranged.
Wherein, the both sides of described car are provided with slide rail, and the inwall of described hoistway is provided with slideway, and slide rail slides even with slideway
Connect.
Wherein, the bottom of described hoistway is provided with support, and the top of support is provided with soft rubber cushion, and the lower end of support is provided with bullet
Spring pad.
The beneficial effects of the utility model are: the top of car of the present utility model connects has seat belt, when elevator is sent out
During raw tenesmus accident rapidly, coiler can timely locked seat belt, prevent car from continuing to drop, thus be effectively prevented from elevator emergency
The generation of speed tenesmus accident；In the normal course of operation of emergency staircase, rising or the decrease speed of emergency staircase are in peace
Within full operational speed range, the folding and unfolding speed of steel wire rope and seat belt is equal with the speed of service of emergency staircase, seat belt
When folding and unfolding speed is within the safe operation speed of emergency staircase, coiler normal folding and unfolding seat belt, the folding and unfolding speed of seat belt
During more than the maximum operational speed of emergency staircase, the locked seat belt of coiler, handrail is set at doorframe, is available for waiting the people of elevator
Group particularly old man or disabled person use, and reduce the physical demands during wait elevator；Meanwhile, different when cage operation
Often, safety door is improper to be opened, and when car does not arrives appointment position, takes elevator personnel imprudence and enter or due to inertia
Can get a grip on the rail in time the when of entrance, it is to avoid take the personnel of elevator and step on sky and fall in hoistway.
Accompanying drawing explanation
Fig. 1 is axonometric chart of the present utility model.
Fig. 2 is car and the structural representation of doorframe of this practicality.
Reference is: 1 hoistway, 2 cars, 3 counterweights, 4 hoist engines, 5 steel wire ropes, 6 seat belt,
7 coilers, 8 doorframes, 9 gates, 10 cylinders, 11 safety doors, 12 supports, 13 soft rubber cushion, 14 springs

Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing 1-Fig. 2, this utility model is made
Further instruction, the content that embodiment is mentioned is not to restriction of the present utility model.
See Fig. 1-Fig. 2, a kind of emergency staircase, the car 2 being arranged in hoistway 1 including hoistway 1, liftable, it is arranged at well
The steel wire rope 5 that counterweight 3 in road 1, the hoist engine 4 being arranged at hoistway 1 top and one end are connected with the top of car 2,
The other end of steel wire rope 5 is walked around hoist engine 4 and is connected with counterweight 3, and the top of described car 2 connects seat belt 6, described well
The top in road 1 is provided with the coiler 7 for folding and unfolding seat belt 6, also includes the doorframe engaged when elevator stops with described car 2
8, doorframe 8 is provided with handrail.
The top of car 2 of the present utility model connects seat belt 6, when there is tenesmus accident rapidly in elevator, and coiler 7
The timely locked seat belt 6 of meeting, prevents car 2 from continuing tenesmus, thus is effectively prevented from the generation of elevator tenesmus accident rapidly；In peace
In the normal course of operation of full elevator, within the rising of emergency staircase or decrease speed are in safe operation velocity interval, steel
The folding and unfolding speed of cord 5 and seat belt 6 is equal with the speed of service of emergency staircase, and the folding and unfolding speed of seat belt 6 is at emergency staircase
Safe operation speed within time, the normal folding and unfolding seat belt 6 of coiler 7, the folding and unfolding speed of seat belt 6 is more than emergency staircase
During the big speed of service, the locked seat belt of coiler 76, handrail is set at doorframe 8, is available for waiting the crowd particularly old man of elevator
Or disabled person uses, reduce the physical demands during wait elevator；Meanwhile, when car 2 operation exception, safety door 11 is non-
Normally open, and car 2 do not arrive appointment position time, take elevator personnel imprudence enter or due to inertia enter when
Can get a grip on the rail in time, it is to avoid take the personnel of elevator and step on sky and fall in hoistway 1.
Wherein, described doorframe 8 includes the top arranging two risers being symmetrical set and two ends with two risers
The transverse slat connected.
Wherein, the medial surface of described riser offers the groove 15 of the length direction setting along riser, and described handrail is by setting
The cylinder 10 being placed in groove 15 forms, and the height of cylinder 10 is equal to the height of riser.Use cylinder 10 as handrail,
The crowd of different heights all can catch cylinder 10, and cylinder 10 is arranged in groove 15, thus avoids cylinder 10 to protrude from
Outside riser, it is effectively guaranteed the passage space of doorframe 8, avoids current personnel to collide with cylinder 10 and injured simultaneously.
Wherein, described car 2 is provided with gate 9, and described doorframe 8 is provided with safety door 11, and the top of car 2 is provided with out
