The specific embodiment
With reference to the accompanying drawings preferred implementation of the present invention is described.
Embodiment 1
Fig. 1 is the constructional drawing of the elevator of expression embodiment of the present invention 1.In the drawings, the top in hoistway 1 be provided with the arranged spaced that separates each other in the horizontal direction, as the first top diversion sheave 2 and the second top diversion sheave 3 of rope sheave.Bottom in hoistway 1 is provided with the actuating device 4 and the bottom diversion sheave 5 of the arranged spaced that separates each other in the horizontal direction.
Actuating device 4 comprises actuating device main body 6 and the driving rope sheave 7 that rotates by actuating device main body 6.Drive rope sheave 7 and bottom diversion sheave 5 and be disposed at roughly the same each other height.In addition, drive the rope sheave 7 and the first top diversion sheave 2 and be disposed on the common plumb line, and constitute a pair of rope sheave.
Volume hangs with many (for simplicity being 1 among Fig. 1) main ropes 8 on the first top diversion sheave 2, the second top diversion sheave 3, bottom diversion sheave 5 and driving rope sheave 7.In hoistway 1, suspend the car 9 that has as lifting body in midair by main rope 8.Car 9 is by propulsive effort lifting in hoistway 1 of actuating device 4.In addition, in hoistway 1, be provided with the control setup 10 that is used to control the elevator running.Actuating device 4 is by control setup 10 controls.
Fig. 2 is the lateral plan of the cord tension adjusting device 13 in the presentation graphs 1.Fig. 3 is the section drawing of the III-III line in Fig. 2.In the drawings, underframe 12a is a pair of horizontal frame of the arranged spaced that separates each other on the depth direction of car 9.On underframe 12a, be provided with and be used to make a pair of actuating device 15 of the second connecting portion 8b with respect to car 9 displacements.Each actuating device 15 arranged spaced that on the Width of car 9, separates each other.Each main rope 8 passes through between each actuating device 15.
Each actuating device 15 has: the rotary driving part 16 that comprises electrical motor; And the screw shaft 17 that extends and undertaken the axle rotation from rotary driving part 16 upward by rotary driving part 16.Between each screw shaft 17, be supported with the Displacement plate 18 that can be shifted along the vertical direction with respect to car 9.Displacement plate 18 screws togather by ball screw structure and each screw shaft 17.Axis direction along each screw shaft 17 is shifted Displacement plate 18 by the axle rotation of each screw shaft 17.That is, by the rotation of each screw shaft 17 to a direction, Displacement plate 18 is shifted to the direction near car main body 11, and passes through the contrarotation of each screw shaft 17, and Displacement plate 18 is to the direction displacement away from car main body 11.
On Displacement plate 18, be provided with a plurality of tension detecting device 19 of the tension force that is used to detect each main rope 8.Each main rope 8 is through Displacement plate 18 and each tension detecting device 19.On each second connecting portion 8b, the fag end accessory 20 that places on the tension detecting device 19 is installed.Each fag end accessory 20 relies on the tension force of each main rope 8 to be pressed against Displacement plate 18 across tension detecting device 19.Thus, each second connecting portion 8b can be with Displacement plate 18 displacements.In addition, measure, measure the tension force of each main rope 8 by the load that is pressed against Displacement plate 18 by 19 pairs of fag end accessories 20 of each tension detecting device.The signal (information) that each tension detecting device 19 produces corresponding to the tension force of each main rope 8.
Each tension detecting device 19 is electrically connected with actuating device 15 and control setup 10 (Fig. 1) respectively.Information from each tension detecting device 19 is sent to actuating device 15 and control setup 10.Each actuating device 15 makes screw shaft 17 rotations according to the information from each tension detecting device 19.Promptly, when the tension force of each main rope 8 is more weak, each actuating device 15 rotates screw shaft 17 by this way: make Displacement plate 18 to the direction displacement near car main body 11, and when the tension force of each main rope 8 was strong, each actuating device 15 rotate screw shaft 17 by this way: Displacement plate 18 is shifted to the direction away from car main body 11.
In addition, control setup 10 obtains from the information of each tension detecting device 19 weight information as car 9.And control setup 10 is according to the running of controlling elevator from the information of each tension detecting device 19.In addition, cord tension adjusting device 13 comprises actuating device 15, Displacement plate 18, tension detecting device 19 and fag end accessory 20.
Below action is described.In the operation process of elevator, the tension force of each main rope 8 is detected incessantly by tension detecting device 19.The tension information of detected main rope 8 outputs to actuating device 15 and control setup 10 respectively incessantly from tension detecting device 19.
When surpassing the preset upper limit value for a certain reason by tension detecting device 19 detected tension force, screw shaft 17 rotates by rotary driving part 16.Thereby Displacement plate 18 is to the i.e. below displacement of direction away from car main body 11.When Displacement plate 18 was shifted downwards, the second connecting portion 8b was also with Displacement plate 18 displacements.Thus, the tension force of main rope 8 reduces, thereby is adjusted in the preset range.
When being lower than the predetermined lower limit value for a certain reason by tension detecting device 19 detected tension force, screw shaft 17 opposite direction rotation of the hand of rotation when surpassing higher limit by rotary driving part 16 with the tension force of main rope 8.Thereby the Displacement plate 18 and the second connecting portion 8b are to the i.e. top displacement of direction near car main body 11.Thus, the tension force of main rope 8 increases, thereby is adjusted in the preset range.
In the cord tension adjusting device 13 of this elevator, the tension force of main rope 8 is detected by tension detecting device 19, make the second connecting portion 8b of main rope 8 be arranged at car 9 with respect to the actuating device 15 that car 9 is shifted according to information from tension detecting device 19, therefore, can cancel the rope sheave that is pressed against main rope 8 for the tension force of adjusting main rope 8.Therefore, can adjust the tension force of main rope 8, can reduce number of components and realize miniaturization with simple structure.Thereby can cost-cutting, and can reduce the space that is provided with of cord tension adjusting device 13.
In addition,, therefore can in the vertical plane of hoistway 1, cord tension adjusting device 13 be configured in the zone of car 9, can reduce the sectional area of elevator in horizontal surface because actuating device 15 is arranged at the bottom of car 9.
In addition, the second connecting portion 8b of main rope 8 is shifted with respect to car 9 along the vertical direction by actuating device 15, does not therefore need to change the direction of main rope 8, thereby can further simplify the structure of cord tension adjusting device 13.
In addition, in above-mentioned example, cord tension adjusting device 13 is arranged at the bottom of car 9, but also cord tension adjusting device 13 can be arranged at the top of car 9.In this case, lanyard portion 14 is arranged at the bottom of car 9.In addition, on cord tension adjusting device 13, be connected with the first connecting portion 8a, in lanyard portion 14, be connected with the second connecting portion 8b.When adjusting the tension force of main rope 8, the first connecting portion 8a is with respect to car 9 displacements.
In addition, also cord tension adjusting device 13 can be arranged on the vertical framework 12c as the sidepiece of car 9.Under this situation, cord tension adjusting device 13 is supported on from the horizontally extending horizontal beam of pars intermedia of vertical framework 12c.Like this, the shift range of the second connecting portion 8b can be limited in the height dimension scope of car 9, thereby can reduce the height dimension of hoistway 1.
