Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car for a side fork type elevator installed in a private house or the like.

[0002]

2. Description of the Related Art As a conventional side fork type elevator, for example, there is one as shown in FIG. In the figure, reference numeral 101 denotes a car which is disposed on the hoistway so as to be movable up and down. The car 101 is a car frame 102 and a cab 10 supported by the car frame 102 via an elastic member 103.
It consists of four. The strength is given to the car frame 102, and the car room 104 does not require much strength. The car 101 is moved up and down by pulling the rope 106 attached to the car frame 102 by the hydraulic cylinder 105.

[0003]

However, in such a conventional side fork-type elevator car, the car frame 102 having the strength is such that the car room 104 is not provided with much strength. From the cab 10
A large one surrounding 4 was needed. Therefore, the car 101 has a problem that the number of parts is increased and the cost is increased, and the assembling process is complicated.

An object of the present invention is to provide a car for a side fork type elevator in which the number of parts is reduced and the assembling process is simplified.

[0005]

In order to achieve such an object, the present invention provides a cab having side panels and a platform made of glass fiber reinforced plastic, a lower frame supporting the platform, and the side panel. And a car frame comprising side frames for supporting the above, wherein the platform has a sandwich panel structure, and the side panels have a sandwich panel structure and carbon fiber is further reinforced.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 7 are views showing an embodiment of a car of a side fork type elevator according to the present invention.

[0007] In FIG. 7, reference numeral 1 denotes a car that is vertically movable on a hoistway 2, and a counterweight 3 is also provided so as to balance the car 1. One end of a rope 4 is fixed to the car 1, the rope 4 is hung on a drive sheave 5 a of a hoisting machine 5, and the other end is fixed to a counterweight 3. When the car 1 is moved up and down by the hoisting machine 5, the car 1 moves along the car guide rail 6. At this time, the counterweight 3 also moves along the counterweight guide rail 7.

The car 1 is, as shown in FIGS. 1 and 2,
The cab 7 is composed of a cab 7 and a car frame 8, and the cab 7 is composed of a platform 9, side panels 10, 11 and a return panel 1.
2, a rear panel 13, and a ceiling 14.

The car frame 8 comprises a lower frame 15 attached to the platform 9 with bolts and the like, and a side frame 16 attached to the side panel 10 with bolts and the like. Roller guides 17 and 18 slidably engaged with the car rail 6 are attached to the lower frame 15 and the side frames 16. The lower frame 15 has a pair of main support members 15a and 15b located on the lower surface of the platform 9, and a pair of sub support members 15c and 15d provided on the main support members 15a and 15b and in contact with the side panel 10. I have.

As shown in FIG. 3, the platform 9 of the cab 1 has a sandwich panel structure 24 made of glass fiber reinforced plastic in order to have strength. Plywood 25a, 25b are located. By making the inside of the sandwich panel structure 24 plywood 25a, 25b,
Even if you accidentally drop a heavy object on the platform 9,
Cracks and breakage are prevented.

As shown in FIGS. 4 and 5, the side panels 10 of the cab 7 are also provided on the left and right sides 10 of the side panels 10.
Each of a and 10b is a plastic sandwich structure 19 reinforced with glass fiber for strengthening (to prevent buckling) and further reinforced with carbon fiber. Is urethane 2
0 is located. As shown in FIG.
1 is laminated only on the glass fiber 22 on the front side, and is not laminated on the glass fiber 23 on the back side.
In addition, a sandwich structure 19 reinforced with carbon fiber
Are also applied to portions 10c and 10d of the side panel 10 where the lower frame 15 and the side frame 16 are located. The rear panel 11, the return panel 12, and the ceiling 14 also have a sandwich structure reinforced with glass fibers.

The car room 7 is suspended by a rope 4 via a lower frame 15 and is supported by a car guide rail 6. At this time, portions 10c and 10 of the side panel 10 where the lower frame 15 and the side frame 16 are located.
d, The left and right side portions 10a and 10b have a sandwich structure 19 reinforced with glass fiber and further reinforced with carbon fiber, so that the side panel 10 has considerable strength. Further, the platform 9 also has a sandwich structure 24, so that it has a considerable strength. For this reason, the cab 7 having the increased strength can be supported only by the lower frame 15 and the side frames 16.

On the other hand, when the car 1 travels along the car guide rail 6, vibration is generated, and the vibration is prevented from being transmitted into the car room 7 by the sandwich structures 19 and 24.

[0014]

As described above, according to the present invention,
Because the platform has a sandwich panel structure and the side panels have a sandwich panel structure and carbon fiber reinforcement, the platform and side panels have considerable strength.

Therefore, the lower frame and the side frames of the car frame can be directly attached to the cab having the increased strength. As a result, the number of parts is reduced and the assembly process is simplified.
