Description
Technical field
The present invention relates to a kind of elevator car safety, particularly a kind of self-help lift safety gear that the function of saving oneself is arranged.
Background technology
As everyone knows, safety tongs all is installed on the elevator.This safety tongs contains frame support, and there is the groove that cooperates with cage guide at the center of frame support, and cage guide is positioned at this groove, and the guide rail both sides in the support have voussoir, rolling body, director and spring from inside to outside successively, and voussoir links to each other with shift mechanism.Two voussoirs wherein are up-narrow and down-wide, and their one sides adjacent with rolling body are the inclined-plane, and rolling body and this inclined-plane offset.When the descending hypervelocity of elevator, by means of velocity limiter and shift mechanism, can make and carry and clamp cage guide on two wedges, make car stop to fall, car is fixed on the guide rail, thereby avoids car " latrine pit " downwards.In case and safety tongs implements to clamp brake, after stopping, car often need the long period to wait for extraneous rescue, lack self-saving ability, will cause serious consequence as meeting with unforeseen circumstancess such as fire, earthquake simultaneously this moment.
Summary of the invention
Lack the problem of escape self-saving ability fast in order to overcome present elevator, the present invention on the basis of not destroying the original reliability of safety tongs, forms a kind of new type of safe pincers of climbing ability voluntarily that have through improving the traditional elevator safety tongs.In case elevator is when emergency situation taking place and can not get external world's rescue in time, the passenger can start self-help lift safety gear voluntarily, makes car rise to exit position, entrance hall nearby, opens elevator door, realizes saving oneself.
In order to reach above-mentioned requirements; The present invention realizes through following technical scheme: it comprises the original safety tongs of elevator: frame support, be shaped on up-narrow and down-wide groove in the support, and cage guide is positioned at this groove; Cage guide both sides in the support are provided with the voussoir that matches with cage guide and groove; Voussoir links to each other with the governor rope of shift mechanism, it is characterized in that setting up safety tongs under the cover below the former safety tongs, and safety tongs becomes serial connection up and down with following safety tongs; The retractor device of maneuvering system control is installed between safety tongs and the following safety tongs; Described safety tongs down includes: the lower bracket of shaped as frame, be shaped on up-narrow and down-wide low groove in the lower bracket, and cage guide is positioned at this low groove; Cage guide both sides in the lower bracket are provided with the lower wedge block that matches with cage guide and low groove, and lower wedge block also links to each other with the governor rope of shift mechanism.
According to the self-help lift safety gear that such scheme is made, when Lift out of order, car can't be opened car door in the middle of being in two floors; Make the retractor device motion with regard to maneuvering system capable of using; The self-help lift safety gear of connection car is had cage guide in arms and is progressively climbed, and the floor opening position that car just can climb nearest cooperates door opener can car door be opened; Personnel withdraw, and reach the purpose of saving oneself.And it Duos down safety tongs of a cover than common safety tongs, so this device is except the function of saving oneself, and at glancing impact, two safety tongss can be embraced cage guide simultaneously, and plaing a part has double insurance, reliability than original better.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further description.
Find out that from Fig. 1 self-help lift safety gear comprises the original safety tongs 1 of elevator, former safety tongs 1 has frame support 2; Be shaped on up-narrow and down-wide groove 3 in the support 2, cage guide 4 is positioned at this groove 3, and cage guide 4 both sides in the support 2 are provided with the voussoir 5 that matches with cage guide 4 and groove 3; Voussoir 5 links to each other with the governor rope 6 of shift mechanism; Setting up safety tongs 7 under the cover below the former safety tongs 1, safety tongs 1 is connected in series up and down for 7 one-tenth with following safety tongs, and the double-acting cylinder 9 of pneumatic manoeuvring system 8 controls as shown in Figure 2 is installed between safety tongs 1 and the following safety tongs 7; Described double-acting cylinder 9 has two, is separately positioned on the both sides of cage guide 4.Described safety tongs 7 down includes: the lower bracket 10 of shaped as frame; Be shaped on up-narrow and down-wide low groove 11 in the lower bracket 10; Cage guide 4 is positioned at this low groove 11; Cage guide 4 both sides in the lower bracket 10 are provided with the lower wedge block 12 that matches with cage guide 4 and low groove 11, and described voussoir 5 and lower wedge block 12 be drawn springs 13 and governor rope 6 priorities interlock mutually respectively.For making self-help lift safety gear have good commonality, it is identical with lower wedge block 12 to be designed to voussoir 5; Support 2 is identical with lower bracket 10.Also except the double-acting cylinder 9 with pneumatic manoeuvring system control 8 between safety tongs 1 and following safety tongs 7, the two-way cylinder that can control with hydraulic control system is as retractor device.
As shown in Figure 1 when elevator normally moves, safety tongs 7 was not worked under safety tongs 1 reached, and governor rope 6 is in relaxed state, and voussoir 5 and lower wedge block 12 be the broad place on the inclined-plane, does not contact with cage guide 4, and self-help lift safety gear does not influence elevator and normally moves.
During Lift out of order; Because hypervelocity descends or the hawser fracture causes car to descend, governor rope 6 tensions make the position fixed ends of extension spring 13 everywhere move on all; Because extension spring 13 limited length are lifted to narrower position, inclined-plane with voussoir 5 and lower wedge block 12; Voussoir 5 and lower wedge block 12 are all with cage guide 4 lockings, and safety tongs 7 was as shown in Figure 3 at A point and B respectively under safety tongs 1 reached, and car stops to descend.If personnel think that the situation is critical in the car, start pneumatic manoeuvring system 8, then self-help lift safety gear gets into climb mode.At this moment, double-acting cylinder 9 elongations are because safety tongs 7 lockings are down shifted safety tongs 1 onto C point jack-up together with car from the A point; Double-acting cylinder 9 shrinks again then, because following safety tongs 7 is packed up in safety tongs 1 locking, following safety tongs 7 draws high the D point from the B point.So back and forth just can realize that car climbs voluntarily.In this process, thus since safety tongs between self-locking, two states of release, switch repeatedly and keep reciprocating the continuing that rise and carry out.Car just can rise to nearest floor opening position, cooperates door opener can car door be opened, and personnel withdraw.The triggering of this self-help apparatus is accomplished by elevator governor rope 6; The required power of fore and aft motion is provided by double-acting cylinder 9 or two-way cylinder; Pressure gas or fluid are stored in the high pressure vessel; So that when power down mode, use, this technology can be implemented for those skilled in the art fully, does not carefully state at this.
