Abstract

PROBLEM TO BE SOLVED: To enable a stepped scaffold to be simply and rapidly installed over an intermediate beam even when the intermediate beam exists between a car stopped due to the failure of an elevator and a rescue-side car brought alongside the car.SOLUTION: Two adjacent elevator cars 10 and 12 each have an emergency rescue port on each of their car sides facing each other. A rescue device for an elevator rescues passengers by allowing the passengers to transfer from the elevator car 10 in failure to the elevator car 12 not in failure. Scaffolds 20A and 20B are stored in the rescue ports of the respective cars. The scaffolds 20A and 20B can be each installed between an intermediate beam 102 which exists between the rescue ports facing each other and the rescue port when the one car 10 is stopped due to the failure, and the other car 12 is brought alongside the one car 10.

Description

  Embodiments of the present invention relate to an elevator rescue device that allows a passenger to be rescued from a failed elevator car.

  In an elevator, an emergency rescue exit is provided on a ceiling portion or a side surface of a car, assuming that a passenger is locked in a car stopped due to a failure.

  In the case of multiple elevators installed in the same building, a rescue exit is provided on the opposite side of the adjacent car, and one elevator breaks down and stops moving in the middle of the hoistway A rescue operation is performed in which the other elevator car is placed next to the elevator car that has failed (see, for example, Patent Document 1).

  When the car that went to rescue is laid down on the car that has failed, the rescuer will exit the rescue car, open the emergency rescue doors on the faulty car, and open both emergency rescue doors. A scaffold is built between the two. And he uses the scaffolding to guide the passengers trapped to the rescue car.

  By the way, in a building where a plurality of elevators are installed, intermediate beams may be scattered between the hoistway sections in the middle of the hoistway of each elevator. Depending on the position where the car is stopped due to the failure of the elevator, the intermediate beam may be located directly beside the car on the failed side. At this time, if the rescue car is placed next to the car on the broken side, there will be an intermediate beam between both cars. When a passenger rescue operation is performed with an intermediate beam in such a position, the intermediate beam becomes an obstacle and the scaffold cannot be bridged, the rescue operation itself cannot be performed, or the scaffold can be bridged. Even in this case, it may be difficult for passengers to transfer to the rescue car.

  Conventionally, in order to facilitate the rescue operation of passengers when there is an intermediate beam, for example, in Patent Document 2, a step-shaped transfer plate is used, and the transfer plate is inverted according to the level difference from the intermediate beam. It proposes to eliminate the step by passing.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an elevator rescue apparatus according to the present invention will be described with reference to the accompanying drawings.
1st Embodiment In FIG. 1, the reference numbers 10 and 12 have shown the elevator car. Of these, one of the cars 10 is an elevator car on the rescue side that has been stopped as a result of a failure in the drive system or control system of the elevator. The other car 12 is a car on the rescue side that is laid next to the car 10 in order to rescue passengers trapped inside the car 10 that has become immobile. The cars 10 and 12 are cars having the same structure, and the car with the car door 14 is the front of the car.

  In this embodiment, the section of the hoistway 100A where one of the cars 10 is raised and lowered and the section of the hoistway 100B where the other car 12 is raised and lowered are adjacent to each other without a wall between them. A plurality of intermediate beams 102 that reinforce the strength of the hoistway are arranged at predetermined intervals in the height direction of the hoistway.

  Emergency exit doors 17 and 18 for opening and closing a passenger's rescue port are attached to car side surfaces 15 and 16 facing each other in the car 10 and the car 12. When the car 10 and the car 12 are located at the same height, the emergency exit doors 17 and 18 are arranged at opposing positions.

  In addition, on the car side surface 15 of one of the passenger cars 10, two frame members 19, 19 are attached in the vertical direction along both side edges of the emergency exit door 17. A passenger rescue scaffold 20A as shown in FIG. Similarly, a scaffold 20B for rescue of passengers is housed in the car side surface 16 of the other car 10 via frame members 19 and 19.

  The passenger rescue scaffolds 20 </ b> A and 20 </ b> B according to this embodiment are composed of a single scaffold plate 21, legs 22 and 22, and step platforms 23 and 24. In the case of this embodiment, the legs 22 and 22 are provided as a pair on the both ends in the longitudinal direction of the steps 23 and 24, and are linked to both ends of the steps 23 and 24. It is configured as a foldable stair-like scaffold. One end of the scaffold 21 is rotatably connected to the frame members 19 and 21 via pins 25.

  The leg 22 is composed of two leg link members 26a and 26b. Among these, the lower end of the lower leg link member 26 a is rotatably connected to the scaffold plate 21 via a pin 27. The upper end of the leg link member 26 a is connected to the lower end of the upper leg link member 26 b and the lower step 23 via pins 28. The upper end of the upper leg link member 26 b is connected to the upper step 24 via a pin 29.

  When the joint portions of the leg link members 26a and 26b connected by the pins 28 are opened from the folded state to 180 °, the joint portions are not bent even when a load is applied from the stepping platforms 23 and 24, and the straight portions are opened 180 °. Is configured to hold.

  As shown in FIG. 4, a scaffolding fixing bracket 30 is attached to the uppermost step 24. In this embodiment, the bracket 30 for fixing the scaffold is made of a U-shaped mold material. The intermediate beam 102 made of H-shaped steel has two flanges 103, 103, and the scaffold fixing bracket 30 can be detachably engaged with the flange 103 of the intermediate beam 102. The scaffolding fixing bracket 30 is fixed to the step platform 24 using a thumbscrew 31. In this embodiment, the scaffold fixing bracket 30 is formed with a long groove 32 having a length in the vertical direction. The thumbscrew 31 is inserted into the long groove 32, and constitutes means for changing the fastening position according to the height of the intermediate beam 102 and adjusting the height of the fixed position.

The elevator rescue apparatus according to the present embodiment is configured as described above. Next, its operation and effects will be described.
First, FIG. 3 shows a state in which the passenger rescue scaffolds 20 </ b> A and 20 </ b> B are folded and stored in the frame member 19. While the elevator is operating normally, in the cars 10 and 12, the folding scaffolds 20A and 20B are mounted on the car side surfaces 15 and 16 of the cars 10 and 12 in a folded state.

  Next, it is assumed that in a situation where a failure occurs in the elevator and one of the cars 10 is in an emergency stop, the other car 12 heads for a passenger who is trapped inside the car 10 for rescue. The car 12 heading for rescue is placed at a position substantially the same height as the car 10. At this time, it is assumed that the intermediate beam 102 happens to be located between the car 10 and the car 12. In addition, the position of the intermediate beam 102 is just a hindrance when the passenger moves from the car 10 to the car 12, for example, it is difficult for the passenger to dive the intermediate beam 102. Suppose you are at a halfway height that makes it difficult to straddle.

  Therefore, in the rescue apparatus according to the present embodiment, as shown in FIG. 2, the rescue personnel riding on the car 12 are the passenger rescue scaffolds stored in the car side 15 of the car 12 on the rescue side. Pull out 20B as follows.

  First, after the scaffolding plate 21 is tilted so as to be horizontal, the arm 22 composed of the arm link members 26a and 26b is extended upward. Then, the bracket 30 attached to the upper step 24 is hooked while matching the height of the flange 103 on the near side of the intermediate beam 102, and the thumbscrew 31 is tightened. Thus, in the rescue-side car 12, a scaffold 20B in which the steps 23 and 24 are stepped can be established.

  Next, the rescuer rides on the scaffold 20B, pulls out the passenger rescue scaffold 20A stored in the car side 15 of the car 10 waiting for rescue, and similarly fixes it to the flange 103 of the intermediate beam 102. The scaffold 20A can be established.

  The rescuer crosses the scaffolds 20A and 20B and opens the emergency exit door 17 of the car 10, so that passengers in the car can leave. Passengers can cross the scaffolds 20A and 20B according to the guidance of the rescue personnel, and can get over the intermediate beam 102 and transfer to the rescue-side car 12.

  As described above, according to the present embodiment, when the car 12 waiting for rescue is laid sideways on the car 10 waiting for rescue, the intermediate beam 102 serving as a rescue obstacle exists. Even in such a case, a step-like scaffold can be established simply and quickly by simply pulling the passenger rescue scaffolds 20A and 20B over the intermediate beam 102 from the car side surfaces 15 and 16 and fixing them to the intermediate beam 102. be able to.

  FIG. 5 shows a case where there is no step between the intermediate beam 102 and the scaffold plate 21. In this case, the scaffold can be established by the horizontal scaffold board 21 only by pulling out the stepped scaffold while being folded to the scaffold board 21 side.

  Next, FIG. 6 is a diagram showing a modification of the present embodiment. The step with the intermediate beam 102 is relatively low, and the bracket 30 may not be fixed to the flange 103 of the intermediate beam 102 when the arm link members 26a and 26b are extended as shown in FIG.

  Therefore, as shown in FIG. 6, as a bracket for fixing the scaffold, a plate-like bracket 40 is attached to the upper step 24, and the brackets 40 are fastened together with a thumbscrew 31 above the intermediate beam 102. The scaffolds 20A and 20B are assembled in a staircase shape.

Second Embodiment Next, an elevator rescue apparatus according to a second embodiment of the present invention will be described with reference to FIGS.
The second embodiment is an embodiment in which a ladder-like scaffold is used instead of a folding step-like scaffold. Both the passenger rescue scaffolds 50A and 50B are ladder-like scaffolds in which a ladder stage 52 is attached to two parallel legs 51 as shown in FIG. The lower end of the leg 51 is attached to the scaffolding plate 21 via a hinge like a hinge.

  According to the second embodiment of the present invention configured as described above, as shown in FIG. 8, the car 10 in a state in which a ladder-like scaffold composed of legs 51 and ladder steps 52 is accommodated on the scaffold plate 21, It can be attached to 12 car side surfaces 15.

  When used for rescue of passengers, as shown in FIG. 7, if the scaffold plate 21 is leveled, the legs 51 are lifted and stood against the intermediate beam 102, and secured using a rope or the like. A scaffold over the beam 102 can be easily and quickly established.

  FIG. 9 shows a case where there is no step between the intermediate beam 102 and the scaffold plate 21. Also in this case, the leg 51 can be established with the horizontal scaffolding plate 21 while being stored in the scaffolding plate 21.

  As mentioned above, although embodiment of this invention was described, these embodiment was mentioned as an illustration and does not intend the restriction | limiting of the range of invention.
