JP 2001-139239 A (page 4, FIG. 1)

  In a conventional elevator car floor device, a compensation rope or the like is suspended through an attachment arm provided on the car floor support frame, and a balance correction device is attached by a mounting base provided on the car floor support frame. For this reason, on the horizontal projection plane corresponding to the car floor support frame, the arrangement position of the equipment mounted under the car such as the compensation rope and the balance correction device is restricted. In addition, the installation position under the car differs depending on the car floor size, the counterweight position of the elevator, and the balance cable size.

  For this reason, there is a problem that the number of types of mounting arms and the like is increased and productivity is lowered. In addition, a car balance correction weight for adjusting the car balance on the car floor is mounted under the car. However, there is a problem that the car balance cannot be corrected because the mounting position of the car balance correction weight under the car is limited.

  The present invention has been made to solve such problems, and an object of the present invention is to provide an elevator car floor device that can easily mount an undercarriage mounting device at an appropriate position on a car floor plane.

  In the elevator car floor device according to the present invention, the car floor disposed in the car frame suspended from the main rope of the elevator, and the lower end of the car frame, wherein the steel material is assembled in a square shape on the horizontal projection plane A car floor support frame provided on the car floor, a vibration isolator provided on the upper surface of the car floor support frame to support the car floor, and a number of through holes for installing equipment installed under the elevator car. The frame is provided with a bottom plate mounted covering the lower surface of the frame.

  In the elevator car floor apparatus according to the present invention, the bottom plate is mounted so as to cover the lower surface of the car floor support frame in which the car floor is supported by the vibration isolator. Then, through the through holes corresponding to the appropriate positions among the many through holes provided in the bottom plate, the under-car mounting devices are respectively mounted at appropriate positions in the horizontal plane direction with respect to the car floor. As a result, although the mounting position under the car differs depending on the size of the car floor, the position of the elevator's counterweight, and the size of the balancing cable, the equipment mounted under the car does not use mounting members such as mounting arms. The problem that the number increases and productivity decreases can be solved. In addition, the mounting position of the equipment mounted under the car is not limited, and it can be mounted at an appropriate place, and there is an effect of facilitating the realization of the required action by the equipment mounted under the car.

Embodiment 1 FIG.
1 to 6 are diagrams showing an embodiment of the present invention. FIG. 1 is a side view of a lower part of an elevator car, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 4 is an enlarged view of a main part of FIG. 1, FIG. 5 is a perspective view showing a fastening state of a mounting bracket on the bottom plate of FIG. 1, and FIG. In the drawing, although not shown, the car floor 1 is arranged in a car frame suspended by the main rope of the elevator.

  A car floor support frame 2 constructed by assembling steel materials in a square shape on the horizontal projection plane is connected to the lower end portion of the car frame, and a vibration isolator made of vibration isolating rubber on the upper surface of the car floor support frame 2. 3 is provided to support the car floor 1 in a vibration-proof manner. A bottom plate 5 provided with a large number of through holes 4 at equal intervals covers the lower surface of the car floor support frame 2 and is attached to the car floor support frame 2. An emergency stop device 6 is disposed under the bottom plate 5 and fastened to the car floor support frame 2.

  A nut 9 is welded to one side 8 of the L-shape of the mounting bracket 7 having an L-shape, and a mounting hole 11 is provided on the other side 10 of the L-shape. 5 is inserted into the through-hole 4 at an appropriate position from the lower side. As a result, the state shown in FIG. 5 is obtained, and the fastener 12 made of a bolt is screwed into the nut 9 from the lower side of the bottom plate 5, and the mounting bracket 7 is fastened to the bottom plate 5 as shown in FIG. 4.

  Instead of the configuration in which the nut 9 is welded to one side 8 of the L-shape of the mounting bracket 7, a screw hole corresponding to the nut 9 is provided on one side 8 of the L-shape of the mounting bracket 7, and the mounting bracket 7 is attached to the bottom plate 5. It can also be set as the structure to fasten. In this configuration, the width of the mounting bracket 7 can be made shorter than the dimension corresponding to the outer diameter of the nut 9, and the diameter of the through hole 4 of the bottom plate 5 can be reduced.

  Then, the car mounting device is mounted on the mounting bracket 7 that is fastened to the bottom plate 5 and disposed at an appropriate position in the horizontal plane direction of the bottom plate 5 through the mounting hole 11. As shown in FIG. 4 and FIG. 6, as the equipment mounted on the lower side of the car, there are mounted a suspended ligament body 13 made of a balanced rope, a car balance correction weight 14, and appropriate optional equipment 15.

  In the elevator car floor apparatus configured as described above, the bottom plate 5 is mounted so as to cover the lower surface of the car floor support frame 2 in which the car floor 1 is supported by the vibration isolator 3 for vibration isolation. Then, the mounting bracket 7 is fastened by the fastener 12 through the through hole 4 corresponding to an appropriate position among the many through holes 4 provided in the bottom plate 5, and is disposed at an appropriate position in the horizontal plane direction of the bottom plate 5. . As a result, the under-car mounting devices such as the suspended ligament body 13, the car balance correcting weight 14, and the optional device 15 are respectively mounted at appropriate positions in the horizontal plane direction with respect to the car floor 1.

  As a result, the equipment mounted under the car does not use a mounting member such as a mounting arm, although the mounting position under the car varies depending on the size of the car floor 1, the position of the counterweight of the elevator, and the size of the balancing cable. The problem that the number of types increases and productivity decreases can be solved. Further, the mounting position of the equipment mounted under the car is not limited and can be mounted in a proper place, and the required action by the equipment mounted under the car can be easily obtained.

Embodiment 2. FIG.
