Description
Technical field
The present invention relates to elevators field, more particularly to a kind of clamping-rope type accidental movement of elevator cage arresting stop.
Background technology
In recent years, the security incident on elevator is reported again and again, people is focused more on elevator safety, such as in the recent period
There have been elevator cab door in open mode, accident is sheared caused by the unexpected accidental movement of lift car.Due to elevator
Car accidental movement is mainly caused by two kinds of reasons：One kind is brake torque deficiency, and another kind is that traction sheave rubs with steel wire rope
Power deficiency is wiped, so to prevent or stop car movement, " device " can be accordingly installed additional on car and directly stop, or pass through folder
Tight traction steel-cable stops indirectly.Therefore, need badly and develop a kind of accidental movement of elevator cage arresting stop, to improve elevator
Security.
The content of the invention
The invention aims to overcome the shortcomings of above-mentioned background technology, there is provided folder a kind of simple in construction and low cost
Rope type elevator car accidental movement arresting stop.
In order to realize the above object a kind of clamping-rope type accidental movement of elevator cage arresting stop provided by the invention, including

Return detector is added between position corresponding to device seat, can so be prevented in the case of the also incomplete return of the present apparatus, elevator
Begin to run, so as to avoid the generation of interference accident.The lower direction return detector 2g rubs installed in the lower direction
Cleaning block 2c lower end, the lower direction return detector 2g are return detection switch.Certainly, other kinds of return can also be used
Detector.
7th input of controller noted above is connected with overhauling elevator signaling switch, and the 8th input of the controller connects
Electric pushrod reset switch is connected to, the 3rd output end of the controller is connected with elevator safety loop switch, the controller
The 4th output end be connected with alarm bell.By the way that the 7th input of controller is connected with overhauling elevator signaling switch, such energy
Ensure that the present apparatus is failure to actuate when being overhauled to elevator, service work is had an impact so as to avoid the present apparatus；Meanwhile
By the way that the 3rd output end of controller is connected with elevator safety loop switch, when so can guarantee that present apparatus action, elevator stops
Only run, so as to be avoided that the present apparatus interferes with elevator；Moreover, the electric pushrod reset switch added can realize electronic push away
The hand-reset of bar, the alarm bell added can play warning function.
As shown in figure 9, the present apparatus is arranged on the position that traction steel-cable 3 is corresponded on elevator load bearing beam 5 by crossbeam 4.
The action process of the present apparatus is as follows：
When the upward accidental movement of elevator, elevator electric switch lock loop disconnects with elevator operation contactor, door area above elevator
Switch first disconnects, and is disconnected below elevator after door area switch, and according to the composite signal, controller judges that elevator is in rise abnormity shifting
Dynamic state；Then, the upper direction electric pushrod 1d elongations of controller control, now, direction is rubbed in upper direction electric pushrod 1d drives
Cleaning block 1c fixes swash plate 1a upward slidings along upper direction, due to upper direction fix swash plate 1a it is diagonally disposed and with upper direction voussoir
1b cooperation, also in downward direction brake pad 2c is drawn close upper direction brake pad 1c simultaneously during upward sliding, due to lower section
To brake pad 2c now transfixions, so the gap between upper direction brake pad 1c and lower direction brake pad 2c diminishes, so as to
So that upper direction brake pad 1c clamps traction steel-cable 3 with lower direction brake pad 2c, and then prevents accidental movement of elevator cage,
Prevent the generation of shearing accident；
When the downward accidental movement of elevator, elevator electric switch lock loop disconnects with elevator operation contactor, door area below elevator
Switch first disconnects, and is disconnected above elevator after door area switch, and according to the composite signal, controller judges that elevator is in and declines abnormal move
Dynamic state；Then, the lower direction electric pushrod 2d elongations of controller control, now, lower direction electric pushrod 2d drive lower direction to rub
Cleaning block 2c fixes swash plate 2a slide downwards along lower direction, due to lower direction fix swash plate 2a it is diagonally disposed and with lower direction voussoir
2b cooperation, also upward direction brake pad 1c is drawn close lower direction brake pad 2c simultaneously during slide downward, due to top
To brake pad 1c now transfixions, so the gap between upper direction brake pad 1c and lower direction brake pad 2c diminishes, so as to
So that upper direction brake pad 1c clamps traction steel-cable 3 with lower direction brake pad 2c, and then prevents accidental movement of elevator cage,
Prevent the generation of shearing accident.
The present invention first, controller runs contactor by elevator electric switch lock loop, elevator, above elevator door area switch and
The composite signal that door area switch provides below elevator judges that elevator is in the shape that rise abnormity is mobile or decline is extremely mobile
State；Then, the upper direction electric pushrod 1d or lower directions electric pushrod 2d actions of the corresponding control of controller, now, upper direction is electronic
Push rod 1d or lower directions electric pushrod 2d will control corresponding to brake pad drawn close to another brake pad, so as to by traction steel-cable
3 clamp, and then prevent accidental movement of elevator cage, prevent the generation of shearing accident；By the way that brake pad and electric pushrod are distinguished
The both sides of fixed swash plate are arranged in, can so facilitate the arrangement between each part, so that the present apparatus is more compact, and then conveniently
The installation of the present apparatus；By adding return detector between brake pad position corresponding with rope brake seat, can so prevent
In the case of the also incomplete return of the present apparatus, elevator begins to run, so as to avoid the generation of interference accident；By that will control
7th input of device processed is connected with overhauling elevator signaling switch, so can guarantee that, when being overhauled to elevator, the present apparatus is not
Action, has an impact so as to avoid the present apparatus to service work；By the way that the 3rd output end of controller and elevator safety are returned
Way switch is connected, and when so can guarantee that present apparatus action, elevator is out of service, so as to be avoided that it is dry that the present apparatus and elevator occur
Relate to；The present apparatus is simple in construction, cost is low, the transformation available for the supporting and old elevator of new elevator.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
