Car 2 has cage 13 and supports the car frame 14 of cage 13.Car frame 14 has a pair of longitudinal framing 17 that couples together between the lower frame 15 of carrying cage 13, the upper frame 16 of top that is configured in cage 13 and each end with lower frame 15 and upper frame 16.
Main rope group 10 is made of many (being a pair of in this example) main rope 18,19.In each end of main rope 18,19, utilize main lanyard part (terminal part) 20 to implement terminal processes.At upper frame 16, be the top of car 2, be provided with the end that is used for a main rope 18 and be fixed on the rope socketing device 21 on the car 2 and be used for end with another main rope 19 and be fixed on rope socketing device 22 on the car 2.
Fig. 3 is the front view on the top of the car 2 in the presentation graphs 2.In the drawings, rope socketing device 21,22 is with state configuration adjacent one another are in the horizontal direction.Each end of main rope 18,19 is configured between the rope socketing device 21,22.In addition, the end of main rope 18,19 and rope socketing device 21,22 are configured between a pair of bearing part 23,24 of being located at upper frame 16.
A rope socketing device 21 has: can be with respect to the dwang 25 of car 2 rotations; Be connected with dwang 25 and by the rotation of dwang 25 with respect to the car 2 displacement body 26 of superior displacement in the horizontal direction; And the force application spring (force body) 27 that between displacement body 26 and bearing part 23, is compressed, produces elastic restoring force.
Dwang 25 can be that rotate at the center with the pivot shaft 28 that is arranged on the upper frame 16.In addition, dwang 25 has: the main rope installation portion 25a that is positioned at rope socketing device 22 sides (that is a side opposite with bearing part 23 sides of pivot shaft 28) of pivot shaft 28; With the displacement body and function installation portion 25b that is positioned at pivot shaft 28 tops.Be connected with the terminal part 20 of the end that be arranged on main rope 18 by pin 29 at main rope on installation portion 25a.On displacement body and function installation portion 25b, be connected with an end of displacement body 26 by pin 29.
By downwards the displacement of car 2 with respect to main rope 18 ends, dwang 25 to make main rope with installation portion 25a towards the direction of top displacement (in Fig. 3, be anticlockwise direction) rotate, by upward the displacement of car 2 with respect to main rope 18 ends, dwang 25 is to main rope is rotated towards the direction (in Fig. 3, being clockwise direction) of below displacement with installation portion 25a.
In addition, rotate to the direction that makes main rope use installation portion 25a to be shifted by dwang 25 towards the top, displacement body 26 is to the direction displacement near bearing part 23, to main rope is rotated towards the direction of below displacement with installation portion 25a, displacement body 26 is to the direction displacement away from bearing part 23 by dwang 25.
Displacement body 26 has: bar (displacement phosphor bodies) 30, and it is connected with displacement body and function installation portion 25b; Adjustment component (spring bearing) 31, it is arranged on the bar 30, can adjust with respect to bar 30 position on (directions of displacement body 26 displacement) in the horizontal direction; And double nuts (registration device) 32, itself and bar 30 screw togather, and are used for the stationkeeping (that is, position) of adjustment component 31 with respect to bar 30.
Force application spring 27 is compressed between adjustment component 31 and bearing part 23.That is, force application spring 27 to opposing displacement body 26 towards near the direction (that is, opposing car 2 is with respect to the direction of the end displacement downwards of main rope 18) of the displacement of the direction of bearing part 23 to displacement body 26 application of forces.Thus, bar 30 bears the application force of force application spring 27 as compressive force.In addition, bearing part 23 bears the counter-force of application force to displacement body 26 from force application spring 27.
By adjustment component 31 is adjusted with respect to the position of bar 30, adjust the application force of force application spring 27.Adjust the tension force of main rope 18 by the application force of adjusting force application spring 27.
Another rope socketing device 22 has: can be with respect to the dwang 33 of car 2 rotations; Be connected with dwang 33, the rotation by dwang 33 and with respect to the car 2 displacement body 34 of superior displacement in the horizontal direction; And the force application spring (force body) 35 that between displacement body 34 and bearing part 24, is compressed, produces elastic restoring force.
Dwang 33 can be that rotate at the center with the pivot shaft 36 that is arranged on the upper frame 16.Dwang 33 has: the main rope installation portion 33a that is positioned at rope socketing device 21 sides (that is a side opposite with bearing part 24 sides of pivot shaft 36) of pivot shaft 36; With the displacement body and function installation portion 33b that is positioned at pivot shaft 36 tops.Be connected with the terminal part 20 of the end that be arranged on main rope 19 by pin 29 at main rope on installation portion 33a.On displacement body and function installation portion 33b, be connected with an end of displacement body 34 by pin 29.
By downwards the displacement of car 2 with respect to main rope 19 ends, dwang 33 to make main rope with installation portion 33a towards the direction of top displacement (in Fig. 3, be clockwise direction) rotate, by upward the displacement of car 2 with respect to main rope 19 ends, dwang 33 is to main rope is rotated towards the direction (in Fig. 3, being anticlockwise direction) of below displacement with installation portion 33a.
In addition, rotate to the direction that makes main rope use installation portion 33a to be shifted by dwang 33 towards the top, displacement body 34 is to the direction displacement near bearing part 24, to main rope is rotated towards the direction of below displacement with installation portion 33a, displacement body 34 is to the direction displacement away from bearing part 24 by dwang 33.
Displacement body 34 has: bar (displacement phosphor bodies) 37, and it is connected with displacement body and function installation portion 33b, and the on even keel configuration; Adjustment component (spring bearing) 38, it is arranged on the bar 37, can adjust with respect to bar 37 position on (directions of displacement body 34 displacement) in the horizontal direction; And double nuts (registration device) 39, itself and bar 37 screw togather, and are used for the stationkeeping (that is, position) of adjustment component 38 with respect to bar 37.
Force application spring 35 is compressed between adjustment component 38 and bearing part 24.That is, force application spring 35 to opposing displacement body 34 towards near the direction (that is, opposing car 2 is with respect to the direction of the end displacement downwards of main rope 19) of the displacement of the direction of bearing part 24 to displacement body 34 application of forces.Thus, bar 37 bears the application force of force application spring 35 as compressive force.In addition, bearing part 24 bears the counter-force of application force to displacement body 34 from force application spring 35.
