The brake mounting piece 11 a is provided to protrude further outward from the outer periphery of the motor frame 11. Such brake attachment pieces 11 a are provided corresponding to the number of electromagnetic brakes 21. Here, it is assumed that the brake attachment pieces 11 a are provided in a state of corresponding to the total of three electromagnetic brakes 21 and protruding from three places on the outer periphery of the motor frame 11. These three brake mounting pieces 11a are arranged so as not to affect the path of the main rope 103 guided to the sheave 105 shown in FIG.

  As an example, the three brake mounting pieces 11a are two positions maintaining a distance of 60 degrees centered on the main shaft 12a above the main shaft 12a of the motor described below, and 1 at the same height as the main shaft 12a It shall be provided at the place. As a result, the electromagnetic brake 21 fixed to the brake mounting piece 11a is arranged asymmetrically with respect to the vertical line passing through the main shaft 12a which is the rotation shaft of the sheave 13.

As shown in FIGS. 4 and 5, the motor frame 11 is provided with a notch 11b at the periphery on the back side corresponding to the location where the brake attachment piece 11a is disposed. The notch portion 11b has a shape in which the outer peripheral wall with respect to the main shaft 12a, which is the rotation shaft of the motor, is cut away and recessed in the direction of the main shaft 12a on the back side of the motor frame 11.

  By providing such a notch 11 b in the motor frame 11, the notch 11 b can be used as a guide for fixing the mounting bracket 33 to be described later to the motor frame 11. Therefore, the mounting bracket 33 can be fixed to the motor frame 11 with good positional accuracy.

<Bearing 12>
The bearing 12 is disposed to face the motor frame 11 on the front side of the motor frame 11 and fixed to the support 10. The bearing 12 supports the main shaft 12 a of the motor of the hoisting machine 1 extended from the motor frame 11 side. The main shaft 12a coincides with the above-described annular accommodation recess and the central axis of the stator attached to the inner surface of the outer peripheral wall.

<Sieve 13>
The sheave 13 has a substantially cylindrical shape, and the middle portion of the main rope 103 is wound around the side periphery thereof. The sheave 13 is provided between the motor frame 11 and the bearing 12 so as to be coaxially fixed to the main shaft 12 a of the motor supported by the bearing 12.

<Brake disc 14>
The brake disc 14 is disposed on the motor frame 11 side of the sheave 13 and has a disk shape that is slightly larger than the sheave 13. The brake disc 14 constitutes a rotary body integrally with the sheave 13 and is provided coaxially with the main shaft 12 a of the motor supported by the bearing 12.

  Further, although not shown here, a rotor (rotor) made of a permanent magnet is provided upright on the surface of the brake disc 14 facing the motor frame 11 side. The rotor is provided on the outer periphery of the stator attached to the motor frame 11 so as to radially face the stator across the air gap with respect to the stator, and is disposed coaxially with the sheave 13 and the brake disc 14 .

Rotate.

<Electromagnetic brake 21>
The electromagnetic brakes 21 are provided in a state of being fixed to the front side of the brake mounting pieces 11 a protruding from the outer periphery of the motor frame 11. Here, it is assumed that the electromagnetic brake 21 is fixed to each of the three brake mounting pieces 11a, and a total of three electromagnetic brakes 21 are provided. 2 and 3 show a state in which one of the three electromagnetic brakes 21 is removed from the brake mounting piece 11a for the sake of explanation.

  Since the hoisting machine 1 is provided with the three electromagnetic brakes 21, the braking force corresponding to the capacity increase of the riding cage 101 is secured, and the fail-safe in which the electromagnetic brakes 21 are multiplexed is achieved. There is.

  Each electromagnetic brake 21 has a brake body 21a and an electromagnetic drive unit 21b fixed to the brake body 21a. Although not shown here, the brake body 21a has a pair of brake shoes for pressing the outer peripheral side surface of the brake disc 14 to brake the brake disc 14, and an armature for holding one brake shoe. The electromagnetic drive unit 21b compresses the brake spring to urge the armature toward the brake disk 14 and compresses the brake spring to release the brake shoe from the outer peripheral side surface of the brake disk 14 to make the sheave 13 rotatable. And an electromagnet. The electromagnet is composed of a combination of an electromagnetic coil and an iron core.

  In the electromagnetic brake 21 having such a configuration, in the braking state, no current is supplied to the electromagnetic coil of the electromagnetic drive unit 21b, and the brake spring biases the armature toward the brake disk 14. As a result, the brake disc 14 is pinched by the brake shoe, and the sheave 13 is maintained in the braking state.

  On the other hand, in the electromagnetic brake 21, in the brake open state, the iron core is excited and the armature is attracted by supplying current to the electromagnetic coil of the electromagnetic drive unit 21 b. As a result, the amateur moves the brake shoe away from the brake disc 14 against the spring force of the brake spring. As a result, the braking force on the brake disc 14 is released, and the sheave 13 becomes rotatable.

<Brake cable 23>
The brake cable 23 is a lead wire drawn from the electromagnetic brake 21, and more specifically, a cable connected to an electromagnetic coil that constitutes the electromagnetic drive unit 21b of the electromagnetic brake 21. In particular, the brake cable 23 has the same length for the plurality of electromagnetic brakes 21. Such a brake cable 23 constitutes a brake member 20 together with the electromagnetic brake 21.

<Relay terminal block 31>
The relay terminal block 31 is a terminal block connected to the electromagnetic brake 21 by the brake cable 23, and is for connecting the brake cable 23 and the relay cable 35 described later. In particular, the relay terminal block 31 is connected to each electromagnetic brake 21 at a 1: 1 ratio via the brake cable 23.

  Such a relay terminal block 31 is attached to the motor frame 11 via a mounting bracket 33 described below. The relay terminal block 31 is assumed to be disposed in the housing.

  The relay terminal block 31 is mounted within the range of the depth dimension of the motor frame 11, that is, within the range of the axial length from the front side to the rear side. As a result, the relay terminal block 31 does not protrude from the axial length direction of the motor frame 11. Therefore, the mounting of the hoisting machine 1 is not performed without increasing the overall bulk of the hoisting machine 1 and without the relay terminal block 31 interfering with the mounting operation in mounting the hoisting machine 1 to the elevator 100. Maintain the work efficiency of

<Mounting bracket 33>
The mounting bracket 33 is a member for fixing the relay terminal block 31 to the outer peripheral edge of the motor frame 11. Each mounting bracket 33 is fixed to a cutout 11 b formed on the back side of the motor frame 11 corresponding to the brake mounting piece 11 a of the motor frame 11.

  Such a mounting bracket 33 is a member having an L-shaped cross section, one of which is a fixed piece 33a and the other of which is a support piece 33b. Among these, the fixing piece 33a is inserted into the cutout 11b from the outer peripheral side of the motor frame 11, and is fixed to the surface facing the back side of the cutout 11b. On the other hand, the support piece 33b is extended toward the front side of the winding machine 1 from the fixing piece 33a fixed to the notch 11b. And the relay terminal block 31 mentioned above is supported and fixed on the upper surface of the support piece 33b, ie, the surface on the opposite side to the motor frame 11. As shown in FIG.

  The mounting bracket 33 as described above is provided with an interval d between the support piece 33 b and the outer peripheral surface of the motor frame 11 in a state of being fixed to the motor frame 11. As a result, the relay terminal block 31 supported on the upper portion of the support piece 33 b is attached to the motor frame 11 with the distance d therebetween via the mounting bracket 33, and the motor terminal 11 generates heat in the motor frame 11. It becomes less susceptible to thermal effects. Therefore, the relay terminal block 31 can accurately transmit the signal from the elevator control board 106 to the brake cable 23 and the electromagnetic brake 21.

  The projection length L of the fixing piece 33a in the mounting bracket 33 as described above is preferably larger than the cutout dimension x of the cutout 11b in the direction from the outer peripheral side of the motor frame 11 to the main shaft 12a. Thus, by using the notch 11b as a guide, the fixing piece 33a of the mounting bracket 33 is inserted from the outer peripheral side of the motor frame 11 to the deepest portion of the notch 11b. A gap d can be reliably provided between the outer circumferential surface.

  The support piece 33 b of the mounting bracket 33 has a length that fits within the depth dimension of the motor frame 11, that is, the length in the axial length direction from the front side to the back side. It is assumed that the mounting piece 11a has a length that does not buffer. As a result, the mounting bracket 33 having an L-shaped cross section is disposed so as to fit within the depth dimension of the motor frame 11, and the mounting bracket 33 and the relay terminal block 31 supported by this are viewed from the axial length direction of the motor frame 11. There is no possibility of spilling out.

<Relay cable 35>
The relay cable 35 is a cable for connecting each relay terminal block 31 and the terminal block 37 described below. The hoisting machine 1 has a number of relay cables 35 corresponding to the number of relay terminal blocks 31, that is, the number of electromagnetic brakes 21. Each relay cable 35 is wired on the back surface of the motor frame 11 and each has a length corresponding to the distance from each relay terminal block 31 to the terminal block 37 or is the same length. Good.

<Terminal block 37>
The terminal block 37 is for connecting each relay cable 35 to a control panel cable 39 described below. The terminal block 37 is commonly connected to the electromagnetic brakes 21 via the relay terminal block 31 and the brake cable 23. Such a terminal block 37 is attached to the motor frame 11 at a position close to the support 10. In addition, although illustration here is abbreviate | omitted, the terminal block 37 assumes that it is provided in the state arrange | positioned in a housing | casing.

<Control panel cable 39>
The control panel cable 39 is a cable for connecting the terminal block 37 and the elevator control panel 106 of the elevator 100 described above with reference to FIG. 1, and the elevator control panel 106 and the electromagnetic brake via the terminal block 37 Connect with 21.

  With the above configuration, the control signal from the elevator control board 106 is transmitted from the brake cable 23 constituting the brake member 20 via the control board cable 39, the terminal block 37, each relay cable 35, and each relay terminal block 31. The electromagnetic brake 21 is transmitted to the electromagnetic brake 21 to drive the electromagnetic brake 21.

«How to attach the hoist 1»
Next, the method of attaching the hoisting machine 1 described above will be described. Here, the case where the winding machine 1 provided with the three electromagnetic brakes 21 newly mentioned above is attached to the existing elevator 100 is illustrated, and an example of the attachment method is demonstrated.

  First, the necessary number of brake members 20 in which the brake cables 23 of the same length are connected to the electromagnetic coils of the electromagnetic brake 21 are prepared. Since the plurality of brake members 20 prepared here have the same length of the brake cable 23, they all have the same configuration.

  Next, with the sheave 13 around which the main rope 103 is wound and the brake disc 14 integrated coaxially with the sheave 13 assembled in the machine room 100b of the elevator 100, the motor frame 11 and the bearing 12 are assembled. The mounted support 10 is fixed. In this state, the terminal block 37 is fixed to the motor frame 11. Further, the mounting bracket 33 is fixed to each notch 11 b of the motor frame 11 in the above-described predetermined state.

  Next, the relay terminal block 31 is attached to the support piece 33 b of each mounting bracket 33 fixed to the motor frame 11. Then, each relay terminal block 31 and the terminal block 37 are connected by the relay cable 35.

In this case, the length of the relay cable 35 connecting the other relay terminal block 31 and the terminal block 37 is adjusted by performing extra length processing, whereby management of the relay cable 35 and wiring work of the relay cable 35 are performed. It can also be easy. With regard to the mounting method of the hoisting machine 1, after the plurality of brake members 20 provided with the brake cables 23 of the same length are attached to the motor frame 11 in a predetermined state, the procedure for connecting the brake cables 23 to the relay terminal block 31 The installation procedure of the other members is not required.
