The speed of the car 4 when Figure 10 is an elevator normal operation in the presentation graphs 1, first crosses that speed and second is crossed speed and the diagram of curves of the relation between 4 the distance from the terminating layer to the car.In the drawings, in hoistway 1, be provided with following two intervals: acceleration and deceleration interval, near its to be car 4 carry out acceleration and deceleration one and another terminating layer interval; With the constant speed interval, it is the interval that car 4 moves with constant speed between each acceleration and deceleration interval.
The speed of car 4 during normal operation, first is crossed speed and second and is crossed speed, according to the change in location of car 4, crosses speed pattern 72 and second along normal speed figure 71, first respectively and crosses speed pattern 73 and change.
Second value of crossing speed pattern 73 is greater than first value of crossing speed pattern 72, and first crosses the value of the value of speed pattern 72 greater than normal speed figure 71.In addition, normal speed figure 71, first is crossed speed pattern 72 and second and is crossed speed pattern 73 and set for respectively: be constant value in that constant speed is interval, reduce continuously towards terminating layer in the acceleration and deceleration interval.
In elevator control gear, be set with normal speed figure 71.The running of elevator control gear control elevator makes car 4 move in hoistway 1 along normal speed figure 71.
Operation is arranged in the acceleration and deceleration interval with guide rail 55.In addition, operation is with guide rail 55 guiding return idlers 60, make in the acceleration and deceleration interval along with car 4 near terminating layer, first and second cross speed reduces continuously.Thus, first crosses speed crosses speed pattern 72 along first and changes, and second crosses speed crosses speed pattern 73 along second and change.
Below, action is described.When car 4 was mobile in the constant speed interval, return idler 60 was fixedly installed on the preposition with respect to car 4, first cross speed and second cross the size of speed constant respectively and with the location independent of car 4.
When car 4 in the acceleration and deceleration interval when terminating layer moves, with the guiding of guide rail 55, return idler 60 moves to the direction near car guide rail 6 corresponding to the position of car 4 by operation.Thereby motion arm 57 is that rotate at the center with turning cylinder 56, and move to the direction of leaving governor sheave 15 according to the amount of movement of return idler 60 engagement section 59.Thus, operating unit 43 moves to the direction of leaving governor sheave 15 with respect to sheave shaft 14 according to the amount of movement of engagement section 59.
When operating unit 43 when the direction of leaving governor sheave 15 moves, adjusting lever 34 is according to the amount of movement of operating unit 43, flies to put 17 normal position and rotates to the direction that radial outside moves to making.Thereby, fly to put 17 normal position to stopping operating position and unlocked position is close, and close amount is corresponding with the amount of spin of adjusting lever 34, first crosses size that speed and second crosses speed reduces corresponding to the position of car 4.
When car 4 in the acceleration and deceleration interval when the direction of leaving terminating layer moves, carry out and above-mentioned opposite action, first crosses size that speed and second crosses speed increases corresponding to the position of car 4.
When normal operation, car 4 is by the control of elevator control gear, and moves in hoistway 1 along normal speed figure 71.At this moment, by the rotation of governor sheave 15, fly to put 17 centnifugal forces that are subjected to move to the degree that stops operating position.
When making the speed of car 4 further rise for a certain reason and the speed of car 4 reaches first when crossing the value of speed pattern 72, fly to put 17 and turn to and stop operating position, switch lever 22 is by 19 operations of action pawls.Thus, the power supply of actuating device 2 control by elevator control gear is stopped, brake equipment moves, and makes car 4 stop.
For example, situation in main rope 3 fractures is inferior, even actuating device 2 stops, car 4 does not stop yet and continues to move, and when the speed of car 4 reaches the value of the second mistake speed pattern 73, fly to put 17 centnifugal forces that produced by means of governor sheave 15 rotations and further rotate, and arrive unlocked position.Thus, engaging pawl 26 gets loose with engaging of trip lever 24 and rotates, and engages with ratchet 25.Like this, ratchet 25 rotates slightly to the hand of rotation of governor sheave 15.
The rotational force of ratchet 25 is by connecting connecting rod 30, spring shaft 29, spring bracket parts 31 and being delivered to arm 27 by pressing spring 32.Thus, arm 27 rotates, and boots 28 are after contact overspeed governor 10, by being compressed against on the overspeed governor 10 by pressing spring 32.Thus, overspeed governor 10 is constrained between governor sheave 15 and the boots 28.
Under the restrained state of overspeed governor 10, car 4 continues to descend, and thus, overspeed governor 10 is pulled to the below, the result, and diversion sheave 9 is moved upward with respect to car 4.Like this, linkage component 62 rotates upward with respect to car 4.
When linkage component 62 rotated upward with respect to car 4, each that is fixed on the public universal driving shaft 67 promptly stopped to rotate upward simultaneously with bar 68, and each voussoir 65 is moved upward with respect to pincers parts 66.Thus, each voussoir 65 is engaging-in between car guide rail 6 and pincers parts 66, so each emergency braking device 7 action.Thereby to car 4 brake activation power, car 4 is forced to stop.
When recovering, by the constraint of removing overspeed governor 10 car 4 is risen, remove the action of each emergency braking device 7.
