Car 3 and counterweight 4 are suspended in the hoistway 1 by many (only illustrating 1 in the drawings) main ropes 9.Top in hoistway 1 is fixed with end connecting portion 10.Main rope 9 has and end connecting portion 10 bonded assembly first end 9a and the second end (not shown).
Fig. 2 is the cutaway view of the elevator hoist 2 among Fig. 1.In the drawings, metal matrix 12 has: be arranged at the 12a of foot of the face of setting, stator installation portion 12b cylindraceous and main shaft cylindraceous insertion section 12c.Stator installation portion 12b and main shaft insertion section 12c dispose coaxially to each other.The internal diameter of stator installation portion 12b and external diameter are greater than internal diameter and the external diameter of main shaft insertion section 12c.
Rotatably mounted on matrix 12 have a metal bowl-shape swivel 13.Bowl-shape swivel 13 has: as the main shaft 13a of the centre of gration of bowl-shape swivel 13; Drive rope sheave 11; And rotor installation portion 13b cylindraceous.That is, on common bowl-shape fixing body 13, be provided with main shaft 13a, driving rope sheave 11 and rotor installation portion 13b integratedly.In addition, main shaft 13a, driving rope sheave 11 and rotor installation portion 13b dispose coaxially to each other.
Main shaft 13a is inserted in the 12c of main shaft insertion section from a side of matrix 12.The inner peripheral surface of driving rope sheave 11 and the outer peripheral face of main shaft insertion section 12c are opposed.That is, main shaft 13a and main shaft insertion section 12c are configured in the inboard that drives rope sheave 11.The outer peripheral face that drives rope sheave 11 is provided with a plurality of grooving 11a that are used to insert main rope 9.
It is adjacent with the opposite side that drives rope sheave 11 that rotor installation portion 13b is arranged in axially going up of main shaft 13a.In addition, the internal diameter of rotor installation portion 13b and external diameter are greater than the internal diameter and the external diameter that drive rope sheave 11.The outer peripheral face of the inner peripheral surface of rotor installation portion 13b and stator installation portion 12b is opposed.That is, stator installation portion 12b is surrounded by rotor installation portion 13b.
Between driving rope sheave 11 and rotor installation portion 13b, be provided with flange part 13c.Flange part 13c is provided with disc mounting part (end difference) 13d.The end of the rotor installation portion 13b side of bowl-shape swivel 13 is an opening.
Between the inner peripheral surface of the outer peripheral face of main shaft 13a and main shaft insertion section 12c, be inserted with a plurality of bearings 14 at interval along axially separating each other of main shaft 13a.Like this, main shaft 13a is to be supported with respect to the main shaft insertion section rotary mode of 12c.
Outer peripheral face at stator installation portion 12b is equipped with motor stator 15.That is, motor stator 15 is by matrix 12 supportings.Inner peripheral surface at rotor installation portion 13b is equipped with and motor stator 11 opposed motor rotors 16.That is, motor rotor 16 can be with bowl-shape swivel 13 rotations.Motor part 17 has motor stator 15 and motor rotor 16, and motor part 17 is used to produce that to make bowl-shape swivel 13 be the propulsive effort of center rotation with main shaft 13a.
On disc mounting part 13d, be fixed with circular brake disc 18.Brake disc 18 is configured in the radial outside that drives rope sheave 11, and rotates integratedly with driving rope sheave 11.Brake disc 18 has the opposed first and second brake surface 18a, 18b mutually.The first and second brake surface 18a, 18b with respect to the plane parallel of the orthogonal axe of main shaft 13a.
Be fixed with detent bearing support 19 on the top of matrix 12.Detent main body 20 is installed on detent bearing support 19.Detent main body 20 has and first brake surface 18a contact, first brake component 21 that separates, with second brake surface 18b contact, second brake component 22 that separates.In addition, detent main body 20 is braked brake disc 18 and the rotation that drives rope sheave 11 by coming with first and second brake plates, 21,22 clamping brake discs 18.Detent 23 has brake disc 18 and detent main body 20.
As detent main body 20, for example use electro-magnetic braking device.In electro-magnetic braking device, by means of the elastic force of retarding spring (not shown) first and second brake components 21,22 are pressed against on the first and second brake surface 18a, the 18b, thereby the rotation of brake disc 18 is braked.In addition,, resist retarding spring first and second brake components 21,22 are separated with the first and second brake surface 18a, 18b by electromagnet (not shown) is carried out excitation, thus brake off.
Be useful on the rotation detector of the rotation that detects main shaft 13a at matrix 12 upper supports, for example coder 24.Coder 24 is installed on the matrix 12 with leaf spring 25 across installing.The end side that is fixed on main shaft insertion section 12c with the base end part of leaf spring 25 is installed.On matrix 12, be provided with in a side opposite and be used to peristome 12d that coder 24 is exposed with main shaft 13a.In addition, coder 24 produces and the cooresponding signal of rotative speed that drives rope sheave 11.Signal from coder 24 is sent to the control setup (not shown) that the running of elevator hoist 2 is controlled.
In such elevator hoist 2, brake disc 18 and the rotation that drives rope sheave 11 are braked by coming with first and second brake components, 21,22 clamping brake discs 18, therefore, compare with the situation on the single face that brake component only is pressed against brake disc, roughly 2 times braking force can be obtained, thereby 20 miniaturizations of detent main body can be made.
In addition, therefore detent main body 20, is compared with the situation that the detent main body is configured in the inboard that drives rope sheave because clamping is configured in the brake disc 18 of the radial outside that drives rope sheave 11, the braking radius can be increased, 20 miniaturizations of detent main body can also be made like this.
In addition, because brake disc 18 and detent main body 20 are configured in the outside of bowl-shape swivel 13, so the maintenance examination operation of the assembling operation of detent main body 20, detent main body 20 and brake disc 18 becomes easy.For example, can easily adjust and confirm gap between brake surface 18a, 18b and the brake component 21,22.
In addition, because main shaft 13a, driving rope sheave 11 and rotor installation portion 13b are arranged on the common bowl-shape swivel 13 integratedly, therefore, can dwindle elevator hoist 2 single-piece axial dimensions.
In addition, because therefore main shaft 13a only can be installed to coder 24 on the matrix 12 with leaf spring by installing with driving rope sheave 11 rotations, the dismounting of coder 24 on matrix 12 is very easy to.Therefore, carry out the installation and the maintenance of coder 24 easily.
In addition, in above-mentioned example, brake disc 18 is made of different individualities with bowl-shape swivel 13, but also brake disc can be arranged on the bowl-shape swivel integratedly.
In addition, in above-mentioned example, elevator hoist 2 is arranged to make main shaft 13a level, but also towing machine 2 can be arranged to make the vertical or approximate vertical of main shaft 13a to use.
In addition, in above-mentioned example, the bottom in hoistway 1 is provided with elevator hoist 2, but the place that is provided with of elevator hoist of the present invention is not limited to this.For example, can be arranged in the top or the machine room on the hoistway 1 in the hoistway 1.
In addition, in above-mentioned example, come suspension craning cab 2 and counterweight 3 with 2: 1 baudriers, but baudrier is not limited to this, for example also can use 1: 1 baudrier.
In addition, as main rope, used the steel rope, but also can use the resin-coating rope that is provided with the outer cladding that constitutes by height friction resin material at peripheral part, the diameter of rope sheave 11, diversion sheave and hanging wheel can be reduced to drive, thereby the space in the hoistway can be saved.
In addition, in above-mentioned example, be S. A. with main shaft 13a, can be anchor shaft also still, the driving rope sheave can be rotated with respect to main shaft with the main shaft.
In addition, can be one also can be a plurality of to the number of detent main body.That is, can on the circumference of a brake disc, dispose a plurality of detent main bodys.
