The cabin 8 is formed of a box having substantially six surfaces surrounded by side walls, and is mounted on a cabin support frame 11 of the chassis 7 and is detachably supported by the chassis 7. That is, the cabin 8 is fixed to the engagement frame 10 and the cabin support frame 11 with bolts on the bottom surface and the front surface (rail 2 side). The cabin 8 has a door 14 on one side for a passenger to enter and exit the cabin.

The drive mechanism 9 includes a motor 15, a speed reducer 16 connected to the motor, and a drive sprocket 17 connected to the speed reducer. An electromagnetic clutch 18 and an electromagnetic brake 19 are provided between the prime mover 15 and the speed reducer 16.
The manual brake 20 is connected to one end of the input shaft of the speed reducer 16. Further, a hydraulic brake 42 is attached to the speed reducer 16. Hydraulic brake 42
Causes the lift main body 3 to move down slowly by applying a hydraulic resistance to the rotation of the braking rotary shaft of the speed reducer 16. The motor 15, the speed reducer 16, the electromagnetic clutch 18, the electromagnetic brake 19, and the manual brake 20 are integrally fixed on a base 21, and are supported on the drive unit support frame 12 via a spring 22 in a vibration-proof manner. I have. The output shaft 23 of the speed reducer 16 is supported at both ends by bearings 26 and 27 via pillows 24 and 25. The bearing members 26 and 27 are connected to the drive unit support frame 12.
And the cabin support frame 11. The drive sprocket 17 is connected to one end of the output shaft 23 of the speed reducer 16 via a one-way clutch 28 and meshes with the rack rail 6.

A driven sprocket 29 is provided above the driving sprocket 17 above the engagement frame 10 of the chassis 7. The driven sprocket 29 meshes with the rack rail 6. This driven sprocket 2
A centrifugal brake 30 is provided on the rotation shaft 9. The centrifugal brake 30 operates and brakes when the descent speed of the elevator body 3 exceeds a predetermined value. A controller box 31 is mounted on the engagement frame 10. In the controller box 31, the motor 15, the electromagnetic clutch 1
8. A control device for electrically controlling the operation of the electromagnetic brake 19 is provided. A brake handle 32 connected to the manual brake 20 is supported on the engagement frame 10.

An operation panel 33 is provided in the cabin 8, and is electrically connected to the controller box 31 via a coupler 34. The operation panel 33 includes a main switch 35, an up switch 36, a down switch 37, and a stop switch 38 of the prime mover. The brake handle 32
It projects into the cabin 8 through an opening in the side wall of the cabin 8 and can be operated inside the cabin 8.

The cabin 8 is transported to the installation site separately from the chassis 7 and assembled at the installation site. FIG.
As shown in FIG. 9, a mounting tongue piece 39 is fixed to a side edge of the cabin support frame 11 of the chassis 7. Mounting tongue 3
Numeral 9 extends sideways with the upper surface of the cabin support frame 11 flush with the upper surface, and has a vertical bolt insertion hole 39a. on the other hand,
A bolt insertion hole 8a corresponding to the bolt insertion hole 39a is provided in a bottom wall of the cabin 8, and a bottom surface is provided with:
An engaging tongue 40 corresponding to the mounting tongue 39 is fixed.
The engaging tongue piece 40 extends parallel to the bottom wall with an interval allowing the mounting tongue piece 39 to be inserted between the engaging tongue piece 40 and the bottom surface, and the bolt insertion hole extends so as not to be directly below 8a. Accordingly, by mounting the cabin 8 on the cabin support frame 11 and sliding the cabin 8, the mounting tongue piece 39 and the engaging tongue piece 40 are engaged, and the bolt 41 is passed through the bolt insertion holes 8a and 39a and tightened with a nut. The cabin 8 can be fixed to the cabin support frame 11. Even if the assembling with the bolts 41 is insufficient, the cabin 8 and the cabin support frame 11
Withdrawal.

The rail 2 is previously attached to a structure such as a steel tower, and the elevator main body 3 is attached to the rail 2. The guide roller 13 can be easily attached and detached for the convenience of assembly. Drive and driven sprocket 1
7 and 29 are engaged with the rack rail 6, and the guide roller 13 is engaged with the guide rail 4 and fixed to the chassis 7.

When the elevator 1 is operated, an operator gets into the cabin 8 and operates the operation panel 33. When the prime mover 15 is started by operating the main switch 35 and the lift switch 36 is operated, the electromagnetic clutch 18 is connected, the electromagnetic brake 19 is released, and the elevator body 3 is raised. When the stop switch 38 is operated, the electromagnetic clutch 18 is disengaged and the electromagnetic brake 19 is operated, so that the elevator body 3 is stopped. When the down switch 37 is operated,
With the electromagnetic clutch 18 disengaged, the electromagnetic brake 19 is released, and the lift main body 3 is slowly lowered by the hydraulic resistance of the hydraulic brake 42 attached to the speed reducer 16. When descending, the speed reducer 16 reverses with the drive sprocket 17. When the elevator body 3 suddenly descends for some reason and its speed reaches a certain value, the centrifugal brake 30 attached to the driven sprocket 29 operates to brake the descending of the elevator body 3. At this time, the speed reducer 16 attempts to continue rotation due to inertia, but the speed reducer 16 is separated from the drive sprocket 17 by the one-way clutch 30, so that the rotation of the speed reducer 16 continues without resistance. Therefore,
The reduction gear 16 is protected from being impacted.

The four guide rollers 13 are all connected to the chassis 7
It is needless to say that the elevator main body 3 should be operated after being fixed to the position. For example, even if the lower guide roller 13 is forgotten to be attached, the elevator main body 3 can move up. However, when the drive sprocket 17 is moving up the rack rail 6
If it is out of the range, the electromagnetic brake 19 and the manual brake 20 on the driving sprocket 17 side become ineffective, and the centrifugal brake 30 on the driven sprocket 29 side plays an important role. This is one of the reasons why the driving sprocket 17 and the driven sprocket 29 are separately provided vertically and separately.
The operations of starting, stopping, ascending, and descending the elevator can be remotely controlled by wireless. In this case, it is possible to stand by by raising or lowering to a predetermined height position unattended.

[0018]

As described above, according to the present invention, the cabin 8 and the chassis 7 holding the drive unit 9 can be easily divided and assembled, and transport is relatively easy, and the drive unit is provided in the cabin. This has the effect of providing an elevator with no overhang 9 and no restriction on the passenger's behavior.
