Embodiment 1

FIG. 1 shows an overall configuration diagram of an elevator apparatus according to an embodiment.

In FIG. 1, 1 is a hoistway, 2 is a car that moves up and down the hoistway 1, and 3a and 3b are car guide rails that are provided on both sides of the car 2 and guide the car 2 up and down. .

Reference numeral 6 denotes a hoisting machine which is a power source for raising and lowering the car 2 and the counterweight 4. The machine 6 has a trajectory 61 on which a main rope to be described later is wound, and a drive unit 62 including a motor for rotating the traction stub 61.

Reference numeral 7 denotes a mounting mechanism for mounting the hoisting machine 6 between the guide rails 5a and 5b. The present embodiment has a feature in this mounting mechanism 7, the details of which will be described later.

8 is a counterweight pulley attached to the upper part of the counterweight 4, 9 is a pulley under the car provided at the lower part of the car 2, and a pulley 9 under the car is provided at the lower part of the car 2.

10 is a main rope wound around a counterweight pulley 8, a traction section 6 1, and a car pulley 9. One end of the main rope 10 is fixed to the main rope attachment portion 11 at the upper end of the guide rail 3a, and the other end is fixed to the main rope attachment portion 12 provided between the guide rails 5a and 5b. .

Since the counterweight pulley 8 is arranged at an angle with respect to the plane passing through the guide rails 5a and 5b in the plan view, the main rope 10 is moved from the traction sleeve 6 1 to the counterweight 8 and the main rope is taken out. It can be fixed to the attachment part 12.

The elevator apparatus rotates a traction machine, 61 of a hoist 6 to raise and lower a car 2 and a counterweight 4 via a main rope 10.

Next, the structure of the mounting mechanism 7 will be described in detail.

FIG. 2 is an enlarged view showing the structure of the mounting mechanism 7, and FIG. 3 is a side view of FIG. 2, which will be described below with reference to these drawings.

The mounting mechanism 7 includes support bases 71a and 71b, a girder beam 72, elastic members 73a and 73b, and a mounting frame 74 as a mounting member.

The supports 7 1a and 7 1b are attached to the guide rails 5a and 5b, respectively, and the girder beam 72 has one end attached to the support 7 1a and the other end attached to the support 7 1b. ing. The main rope attachment portion 12 described above is provided on the girder beam 72. The elastic members 73a and 73b are mounted on the girder beams 72 and are made of an elastic material such as rubber. A mounting frame 74 for the hoist is installed on the elastic members 73a and 73b. The hoisting machine 6 is attached to the attachment 74, and the structure is such that it can be slightly moved in the longitudinal direction of the guide rails 5a and 5b (vertically).

As shown in FIG. 3, the hoisting machine 6 is mounted on a mounting frame 74. In order to prevent the main ropes 10 from coming into contact with the guide rails 5a, b and the counterweight 4, as shown in Fig. 3, the traction sleeve 61 (indicated by a dotted line) passes through the guide rails 5a, 5b. It is installed in a position deviated from.

The mounting frame 74 is a frame composed of horizontal members 742 and 743 and vertical members 741a and 741b as shown in FIG. In addition, measuring tables 744a and 744b are attached to the vertical members 74la and 741b, respectively, and the hoisting machine 6 is fixed to the horizontal member 742 and the fixing tables 744a and 744b.

Lower stoppers 745a and 745b are attached to lower ends of the vertical members 74la and 741b, respectively. The lower end surfaces of the vertical members 741a and 741b abut on the elastic members 73a and 73b as shown in FIG.

Further, as shown in FIG. 2, upper sway members 746 a and 746 b are attached to the left and right sides of the lateral member 742, and lower sway members 747 a and 746 a to the vertical members 741 a and 74 lb, respectively. 747b is attached.

5, 6 the upper Futome member 746 a and the lower Futome member 747 is an enlarged view of a _c Figure 5, the upper Futome member 746 a as shown in 6, which Hythe lower Futome member 747 a The guide rail 5a is sandwiched between conductive materials. The upper sway member 746b and the lower sway member 747b also have the same structure as the upper sway member 746a and the lower sway member 74.7a, and both sandwich the guide rail 5b via an elastic material. With this configuration, it is possible to prevent the micro-vibration of the hoisting machine 6. Further, in the above configuration, since the mounting frame 74 is guided by the guide rails 5a and 5b and can be slightly moved up and down, the vertical force applied to the hoisting machine 6 is reduced by the elastic members 73a and 73b. Is supported by the support 71a, 7 lb through the support. . Upper stoppers 7448a and 7488b are provided on the left and right sides of the lateral member 742 so as to protrude from the guide rails 5a and 5b, respectively. The stop members 746a and '746b may also serve as attachment portions to the horizontal members 742.) The upper stoppers 748a and 748b, together with the lower stoppers 7 _: 45a and 745b, prevent lateral runout that cannot be suppressed by the vibration-preventing member. Even if a large run-out occurs due to the moment acting on the hoisting machine 6, the upper stoppers 748a, 748b and the lower stoppers 745a, 745b and the guide rail 5a , 5b can prevent the mounting frame 74 from running sideways. In the above configuration, even when a downward force F is applied by the main rope 10, the moment generated by the force F is applied to the upper stoppers 748a, 748b and the lower stoppers 745a, 747. It can be dispersed and supported by 4 5 b. On the other hand, the vertical load of the mounting frame 7 and the hoisting machine 6 acts on the supports 71a and 71b, and supports these loads.

Thus, the moment due to the reaction force acting on the guide rails 5a and 5b can be reduced, and the size of the guide rail can be reduced.

Further, since the elastic members 73a and 73b are provided between the mounting frame 74 and the cleat beams 72, vibration of the hoisting machine is transmitted to the guide rails 5a and 5b. Can be reduced. The deflection of the elastic members 7 3 a and 7 3 b may cause slight lateral runout of the mounting frame 74, but this lateral run-out is caused by the upper vibrating members 7 46 a and 7 4 6 b and the lower vibrating sides. It can be prevented by the members 747a and 747b.

Further, in the mounting structure of the hoist, the hoist 6 is disposed between the guide rails 5a and 5a. The space between the guide rails 5a and 5b is an area that has conventionally been a dead space, and by using this space, the space in the hoistway can be effectively used.

In addition, since the girder beam 72 is fixed to the supports 71a and 71b, the positional relationship between the hoisting machine 6 and the girder beam 72 becomes unnecessary. In the case of the conventional example, since a beam is provided on the guide rails 5a and 5b and a hoisting machine is installed on the beam, a dimension in the height direction is required. In this case, this space becomes unnecessary. Embodiment 2.

The guide rail connecting portion 13 can prevent the guide rails 5a and 5b from being encroached.

In this embodiment, the configuration of the guide rail connecting portion 13 as described above is used. However, the configuration shown in FIG. 9 may be used. In FIG. 9, one end of each of the connecting members 134a and 134b is fixed to the 'projection' which is the sliding surface of the guide rail 5a, and the other end is fixed to the projection of the guide rail 5b. For fixing, through-holes are formed in the protrusions at the upper ends of the guide rails 5a and 5b, and the couplings 134a and 134b are fixed to the through-holes through bolts. In the first and second embodiments, the girder beam 72 is mounted on the support 71 a, 7 lb, and the elastic members 73 a, 73 b are further provided thereon. May be configured not to be interposed between the support bases 71 a and 71 b and the elastic members 73 a and 73. In this case, connect the end of the main rope 10 to the top of the hoistway. Must be attached to wells and other parts.

Further, the hoisting machine 6 may be fixed to the mounting frame 74 via an elastic member.

Furthermore, in the above embodiment, the supports 7 la and 71 b are attached to the guide rails 5 a and 5 b, respectively, but one end is attached to the guide rail 5 a and the other end is attached to the guide rail 5 a. The support base can also be constituted by a beam-shaped member attached to b.

In the above embodiment, the case where the hoisting machine is attached to the guide rails 5a and 5b for the counterweight is described. However, the case where the hoisting machine is attached to the guide rails 3a and 3b for the car. It may be applied the structure of the invention ₍
