The specific embodiment
Fig. 1 illustrates according to elevator of the present invention, and this elevator comprises lift car 1, and elevator S and the equipment that is used to make the motion of lift car (not shown) for example are supported on hauling block machine and ropes on the building.Lift car 1 comprises drg 2, and movable mechanical stops 6 is connected to this drg 2, and through making this hill holder 6 motions, drg 2 is arranged to be transferred to braking position.Elevator S comprises mechanical stops 5.Be arranged between position I and position II, move at the hill holder on the lift car 6, the I in the position, hill holder 5,6 on collision course, the II in the position, hill holder 5,6 is not on collision course.This end of move distance has been that hill holder 5 and 6 collided each other when hill holder 6 was in position I after the certain distance towards the end of elevator when lift car 1.Thereby hill holder 6 makes drg 2 be transferred to braking position when being arranged to be in the desired location by means of the motion of the bearing force of hill holder 5 with convenient lift car.When drg 2 had moved to braking position, the motion of lift car stopped after certain stopping distance.It is a suitable distance that hill holder 5 is arranged to end apart from elevator, even if so that after a stopping distance, still between the end of lift car 1 and elevator S, keep the space to people's safety.
Elevator comprises the controollable equipment (7,8,9) of the position that is used to influence hill holder (6), is used to influence the controollable equipment (7 of the position of hill holder (6); 8,9), through controlling this equipment (7,8; 9), hill holder (6) can move between position I and position II, the I in the position, and hill holder on the lift car and the hill holder in the elevator are each other on collision course; The II in the position, hill holder (5,6) is not on collision course.Equipment (7,8,9) comprises controollable actuator 7, and the controller 10 that is used for control convenience (7,8,9).Equipment 7,8,9 can control so that hill holder 6 switches to pattern II or vice versa by the signal of controller from pattern I through controller 10, and perhaps it can remain on main pattern.Is according to Fig. 2 from a mode switch to another, realizing shown in 3a and the 3b.By the signal of controller 9, actuator 7 is arranged on hill holder 6, applying a power on the direction Z, and this power pulls to position II with hill holder 6.In addition, passive (passive) power unit is arranged to act on the hill holder, and this power unit is a spring 8 in preferred solution.This spring is arranged to attempt when hill holder 6 is in position II, make hill holder 6 I motion towards the position.By means of passive power unit, the mode that hill holder 6 is arranged to attempt with fail safe moves to position I.When hope made hill holder 6 move to position II, actuator 7 overcame the power of spring 8 and moves hill holder to position II.Hill holder is remained on position II can be realized with it through actuator 7 the most simply, but in the illustrated embodiment, it is carried out through controollable power unit 9, and this controollable power unit is electromagnet preferably.The advantage of power unit 9 is that the size of actuator 7 is littler and energy consumption is lower.When hope made hill holder 6 move to position I, the pulling of actuator and/or electromagnet was stopped and spring 8 is drawn to position I with hill holder 6.Spring 8 can be individually or is assisted by actuator 7 and to carry out this.Equipment (7; 8; 9), it is arranged in the driven of elevator, hill holder (6) remained on position II and will when the behaviour of the end of elevator forms, make hill holder 6 move to position I when the space (survival space) of safety by the signal control of controller 10.Through by means of equipment 7,8,9 make hill holder 6 move to position I and are provided with under the preferred situation at least below of survival space:
-when equipment (7,8,9) cuts off the power supply,
If-vital circuit is broken off by controller 10 controls,
If-be used for detecting Equipment Inspection that elevator swarms into in elevator, having swarmed into by controller 10 controls.
Controller 10 is associated with electric life controller, or it can be independent control unit.Controller 10 can for example pass through electric signal control convenience 7,8,9.Actuator 7 is the actuator of electric power operation preferably, for example screw actuator.Aforesaid control signal can be for example to supply with to equipment 7,8, and the variation of 9 control current is for example broken off or increased, or the method for any other prior art no matter.Control signal can be wirelessly or wiredly is transferred to equipment 7,8,9.
The mobility of hill holder 6 is to arrange that through with the mode movable with respect to transmission equipment it being supported on the transmission equipment 12 this transmission equipment 12 is mechanically connected to drg 2.Transmission equipment 12 is supported on the lift car 1 via horizontal shaft 13, and hill holder 6 is around this horizontal shaft pivot when meeting when hill holder (5,6), and by means of this pivoting action, the motion of the hill holder 6 that hill holder 5 and 6 causes is passed to drg 2.Through equipment (7,8,9), hill holder 6 can be gone up motion in the direction (direction z) of aforesaid horizontal shaft with respect to transmission equipment 12, so that hill holder is moved between position I and position II.For this reason, hill holder 6 is fixed to transmission equipment 12 with hinging manner (joint 41).Such advantage is that the actuation direction of hill holder 6 is essentially the right angle with respect to the direction that hill holder 5 and 6 collisions the time act on the power on the hill holder 6.The equipment 7,8,9 that influences the position of hill holder is supported on the transmission equipment 12 with the mode of transmission equipment 12 motions to allow them.Owing to these reasons, the motion of hill holder 6 can not apply big load on equipment (7,8,9) when hill holder 5 and 6 collisions.On the other hand, this has also improved the compactedness of structure.The position of hill holder (6) confirms that by equipment 15 this equipment 15 is connected to controller.Hill holder 6 is preferably a roller, and this roller is included in the horizontal shaft that rotates on the direction identical with the tiliting axis that transmits equipment.
By hill holder (5; 6) braking of the drg 2 that causes of collision is arranged to be that a distance stops lift car 1 in the end apart from elevator each other, and said lift car advances towards said end so that artificial safe space is retained between the end of lift car and elevator before braking.This layout that can pass through hill holder (5,6) realizes.When the lift car of driven rests in nearest floor place, aforesaid end, between lift car and elevator, there is not retained personnel's survival space.In this case; The elevator of arranging according to the present invention is particularly advantageous; Because this elevator can be the elevator that has the elevator of lower bottom gap and/or have low top clearance, this elevator can be safe through actuating that hill holder 6 is converted in its bottom gap and top clearance.The bottom (with mode shown in Figure 1) of threshold preferred distance elevator of the door D of minimum elevator floor is 0.5 meter at the most, preferably at the most 0.25 meter, distance.In this case, lift car must advance under driven and approach the end.Because the big clearance envelope that the people can get into is not safely wherein stayed the end under the driven situation, so the pit of elevator can still be kept more shallow or even can be omitted fully.
As shown in Figure 1, drg 2 most preferably is the drg corresponding to guide rail 3, but it alternately is other type, for example, and corresponding to the drg of elevator rope.Near the both ends of elevator S, there is hill holder 5.On the lift car will be through controller motion hill holder 6 thereby be particularly advantageous because through making a hill holder motion, at both ends portion has realized safe space under the situation that does not get into elevator.Yet like hope, hill holder 5 also can be installed near the only end of elevator S.When hill holder 5 was installed in the two ends of elevator, drg 2 must can be braked the motion that on both direction, takes place.Drg 2 is beidirectional safety device preferably in this case.When stopper means only during the end at elevator, drg 2 can be the safety device of any prior art type, preferred unidirectional safety device.
When lift car 1 elevator S vertically on motion enough far so that hill holder (5 and 6) when colliding each other; Hill holder 5 begins to make hill holder 6 to move on the horizontal x of elevator with respect to hill holder 5, and hill holder 6 moves on the sense of motion y of lift car with respect to hill holder 5 simultaneously.This can make hill holder 6 during the braking of lift car 1, continue the motion stop up to lift car.This is that geometric configuration through hill holder 5 and 6 realizes.Hill holder 5 comprises guidance surface A, and after hill holder 5 and 6 collisions, hill holder 6 moves along guidance surface A.Hill holder surfaces A in the vertical direction be elongated and after hill holder 5 and 6 collisions hill holder 6 for example slide or roll, so that the contact point between hill holder 5 and 6 highly changes to second height from first along it and lean on it to move.The elongated shape of hill holder (5) can make hill holder (6) on direction X, move; Owing to the guiding effect on hill holder surface with because support effect causes beginning braking, and after beginning; When the motion of lift car continues; Hill holder 6 advanced along the hill holder surface so that the contact point between hill holder 5 and 6 from first high degree of motion to the second height, this prevents that hill holder (6) from move backward, thereby guarantees to continue to brake.Hill holder (5) is supported on the elevator or on its fixed sturcture, on the preferred guide rail (3).Hill holder 5 is preferably supported in the horizontal flexibly, preferably via spring 16.Advantage is give way (the giving way) of hill holder under collision situation, in the case since for example damping with allow flexible, reduced to the damage susceptibility.Yet flexible size is enough on hill holder 6, produce enough big bearing force so that actuate drg 2 so that resist this flexible power.
In the method that is used for forming survival space according to the present invention in the end of elevator; Wherein lift car temporarily can not advance to this survival space; Said survival space forms through hill holder (6) on the lift car (1) is moved on the route with hill holder (5) collision in elevator (S); Because the collision of said hill holder (5,6), the braking of the drg (2) on the lift car (1) are arranged to beginning.Elevator comprises the controollable equipment (7 of the position that is used to influence hill holder (6); 8; 9), and in the method, the hill holder (6) on the lift car (1) is through controlling aforesaid equipment (7 with the controller (10) that is included in the elevator; 8,9) move on the route with the collision of hill holder (5) in elevator (S).This method is to realize in the mode shown in the application's the elsewhere with reference to Fig. 1-3b.Said elevator thereby be according to the content that provides at the application's elsewhere Fig. 1-3b for example.Through this method; Through controlling aforesaid equipment (7 with the controller (10) that is included in the elevator; 8; 9) hill holder (6) on the lift car is moved on the route that collides with hill holder (5) at the top of elevator (S) and bottom end vicinity, survival space preferably side by side is formed on the two ends of elevator.
In the preferred solution that illustrates, when hill holder 6 moved to position I, it is upward motion of z in the horizontal direction basically, and this direction z is perpendicular to aforesaid perpendicular (xy plane).In the preferred solution that illustrates, this motion is carried out with hinging manner, but it also can carry out under the situation of hinge not having, for example through the straight motion on direction z.When said solution is pivotally attached, extend to the arm of the hill holder 6 of joint 41, like what see,, hill holder 6 is being parallel to transmission equipment 12 when being in position I from the top, and angled when hill holder is in position II.In this case, under collision situation, produced minimum unfavorable moment of torsion.
When mentioning that hill holder 6 is on lift car in this application, it refers to hill holder 6 and is connected with car and is supported on the car.Obviously, shown stopper means 5 also can be near the only end of elevator.Those skilled in the art are apparent that; The invention is not restricted to aforesaid embodiment; In these embodiment; Use some examples to describe the present invention, but many modifications of the present invention and various embodiment all are fine in the scope of the inventive concept that is limited the following claim that provides.
