Detailed Description
Fig. 1 is a front view showing key parts of an elevator including an elevator hoisting machine base fixing device according to embodiment 1 of the present invention. The elevator is provided with: a car, not shown, which is a lifting body that moves up and down in the hoistway 1; a counterweight 2 that is a lifting body that lifts and lowers in the hoistway 1; a pair of guide rails 3 for guiding the lift of the car; and a pair of guide rails 4 that guide the raising and lowering of the counterweight 2. In fig. 1, one guide rail 3 of a pair of guide rails 3 is shown. One guide rail 4 of the pair of guide rails 4 is disposed in the vicinity of the one guide rail 3. The other guide rail 4 of the pair of guide rails 4 is disposed farther from the one guide rail 3 than the one guide rail 4. One guide rail 4 of the pair of guide rails 4 is defined as a first guide rail 4A, and the other guide rail 4 of the pair of guide rails 4 is defined as a second guide rail 4B.
Further, the elevator comprises: a rope 5 which is a suspension body supporting the car and the counterweight 2; a hoisting machine 6 around which a rope 5 is wound; and a base 7 that supports the hoisting machine 6. By driving the traction machine 6, the ropes 5 are moved. The car and the counterweight 2 are raised and lowered in opposite directions to each other in the hoistway 1 by the movement of the ropes 5. The frames 7 are respectively mounted on the pair of guide rails 4. Therefore, the housing 7 and the pair of guide rails 4 overlap each other when viewed from above. Further, the upper portions of the pair of guide rails 4 are fixed to the base 7. A guide rail 3 is fixed to the frame 7.
The elevator includes a plurality of brackets 8 fixed to a wall of the hoistway 1. The plurality of brackets 8 are arranged at intervals in the height direction. In fig. 1, the tray 8 arranged at the highest position among the plurality of trays 8 is shown. Among the plurality of brackets 8, the bracket 8 disposed at the highest position is defined as a top bracket 8A.
The top bracket 8A is a fixing member fixed to a wall of the hoistway 1 at a position above the machine base 7. No bracket 8 is disposed in a portion of the wall of the hoistway 1 corresponding to the upper portion of the guide rail 4.
Further, the elevator has a load bearing member 9 provided across the second guide rail 4B and the top bracket 8A. Further, the elevator comprises: a plurality of rail clips 10 that fix the load bearing member 9 to the top bracket 8A; and a plurality of fasteners 11 for fixing the load support member 9 to the upper portion of the second rail 4B. The fastener 11 has a bolt and a nut. The load support member 9 is disposed outside the base 7 in the width direction of the base 7. The pair of guide rails 4 are arranged apart from each other in the width direction of the base 7.
The bracket 8 has: a first L-shaped member fixed to a wall of the hoistway 1; and a second L-shaped member fixed to the first L-shaped member. The rail clip 10 is provided to the second L-shaped part of the bracket 8.
The elevator includes a plurality of brackets 12 fixed to a wall of the hoistway 1. The plurality of brackets 12 are arranged at intervals in the height direction. In fig. 1, the tray 12 disposed at the uppermost position among the plurality of trays 12 is shown. Among the plurality of brackets 12, the bracket 12 disposed at the highest position is fixed to the wall of the hoistway 1 at a position above the machine base 7.
The elevator further includes a plurality of rail clips 13 for fixing the guide rail 3 to the bracket 12. The upper portion of the guide rail 3 is fixed to the bracket 12 disposed at the highest position, and the upper portion of the first guide rail 4A is fixed to the upper portion of the guide rail 3 via the base 7. Thus, the upper portion of the first guide rail 4A does not need to be fixed to the bracket 8.
The bracket 12 has, similarly to the bracket 8: a first L-shaped member fixed to a wall of the hoistway 1; and a second L-shaped member fixed to the first L-shaped member. The rail clip 13 is provided to the second L-shaped part of the bracket 12.
An elevator hoisting machine base fixing device for fixing a base 7 to a hoistway 1 is configured to include one guide rail 3, a pair of guide rails 4, a plurality of brackets 8, a load support member 9, a plurality of rail clips 10, a plurality of fasteners 11, a plurality of brackets 12, and a plurality of rail clips 13.
The guide rail 4 is formed in a T-shaped cross section. The load support member 9 is formed in a T-shaped cross section. The cross-sectional shape of the load support member 9 is the same as the cross-sectional shape of the guide rail 4. The load support member 9 has a flat plate-shaped base portion 14 and a guide portion 15 provided on the base portion 14. The guide portion 15 is disposed outside the base portion 14 in the width direction of the housing 7. The base 14 overlaps the back surface of the second rail 4B. The load support member 9 is fixed to the second rail 4B in a state where the base 14 overlaps the back surface of the second rail 4B. Base 14 is secured to top bracket 8A using a plurality of rail clips 10.
Next, a procedure of fixing the machine base 7 to the hoistway 1 using the machine base fixing device for an elevator hoisting machine will be described.

Thereafter, the load support member 9 is fixed to the upper portion of the second rail 4B using the fastener 11, and the load support member 9 is fixed to the top bracket 8A using the rail clip 10. At this time, the load support member 9 is disposed outside the base 7 in the width direction of the base 7. Thereby, the machine base 7 is fixed to the hoistway 1.
As described above, according to the elevator hoisting machine base fixing apparatus according to embodiment 1 of the present invention, the load support member 9 is provided across the upper portion of the second guide rail 4B and the top bracket 8A. This allows the upper portion of the guide rail 4 to be fixed to the top bracket 8A provided above the base 7.
The load support member 9 is disposed outside the housing 7 in the width direction of the housing 7. This can suppress reduction in the working space on the base 7. As a result, the operator can easily set the hoisting machine 6 on the base 7.
Further, the load support member 9 has a flat plate-shaped base portion 14, and the base portion 14 overlaps the back surface of the second rail 4B. This facilitates fixing of the load support member 9 to the second rail 4B.
The cross-sectional shape of the load support member 9 is the same as the cross-sectional shape of the second rail 4B. This facilitates formation of the load support member 9.
Fig. 2 is a front view showing an elevator hoisting machine base fixing device according to embodiment 2 of the present invention. The load bearing member 9 is provided across the housing 7 and the top bracket 8A. The load bearing member 9 is fixed to the housing 7 using fasteners 11. The base 14 overlaps with the side of the housing 7. The load support member 9 is fixed to the base 7 in a state where the base 14 overlaps with the side surface of the base 7. The other structure is the same as embodiment 1.
As described above, according to the elevator hoisting machine base fixing device according to embodiment 2 of the present invention, the load support member 9 is provided across the base 7 and the top bracket 8A.
