When the machine room unit 4 moves, the telescopic support 6 shortens. The machine room unit 4 includes a hoisting machine 5, a control panel not shown, a governor, and the like.
The guide rail 7 is provided in a vertically standing state inside the hoistway 1. As described below, the guide rails 7 include a pair of guide rails ( car guide rails 7a and 7b) for the car 2 and a pair of guide rails ( counterweight guide rails 7c and 7d) for the counterweight 3.
The car 2 and the counterweight 3 are suspended from the machine room unit 4 by main ropes 16 wound around sheaves of the hoisting machine 5, and are lifted and lowered along guide rails 7 inside the hoistway 1. The car 2 and the counterweight 3 are connected to each other by a main rope 16.
The second support member 10 is composed of, for example, a plurality of beam-like members, is positioned above the support member 9 and the work platform 11, is supported by the building, and supports the work platform 11.
The work platform 11 is suspended from the second support member 10 by the work platform crane 12, is positioned above the support member 9, and is movable in the elevating direction of the car 2 by the work platform crane 12. An operator of the elevator installation work enters the work platform 11 and performs an installation work of the guide rail 7 and equipment (not shown) in the hoistway 1.
The support member 9 includes an extendable support portion 13, a guide shoe 14, and an emergency stop portion 15, and is supported by the building (the wall of the hoistway 1) via the extendable support portion 13. The telescopic support portion 13 is a member that is telescopic in a direction toward a wall of the hoistway 1, and when extended, the support member 9 is supported by the building, and when shortened, the support member 9 is movable in the lifting direction of the car 2. Any prior art technique may be used to move the support member 9. For example, the support member 9 may be moved by any device such as a crane provided on the second support member 10 or a tower crane provided outside the hoistway 1.
Fig. 2 is a plan view showing a support member 9 of the construction elevator apparatus according to the present embodiment. The support member 9 is provided inside the hoistway 1. A pair of car guide rails 7a and 7b and a pair of counterweight guide rails 7c and 7d are provided inside the hoistway 1. The car guide rails 7a and 7b face each other to guide the up-and-down movement of the car 2. The counterweight guide rails 7c, 7d face each other and guide the raising and lowering of the counterweight 3. In this embodiment, the direction in which the car guide rails 7a and 7b face each other is the same as (parallel to) the direction in which the counterweight guide rails 7c and 7d face each other.
The support member 9 comprises a plurality of beam-like members. As an example, fig. 2 shows a support member 9 comprising four beam- like members 9a, 9b, 9c, 9 d. The beam- like members 9c and 9d extend in a direction (the left-right direction in fig. 2) in which the car guide rails 7a and 7b face each other. The beam- like members 9a and 9b extend in a direction (vertical direction in fig. 2) orthogonal to the direction in which the beam- like members 9c and 9d extend. The support member 9 comprises a plurality of beam-like members, so that the machine room unit 4 and the crane 8 for machine room unit can be supported more balanced.
The support member 9 has a pair of telescopic support portions 13 on at least one beam-like member, and is supported by the building (the wall of the hoistway 1) through the telescopic support portions 13. The support member 9 shown in fig. 2 has a pair of telescopic support portions 13 for the beam- like members 9a and 9b, respectively. The pair of telescopic support portions 13a, 13b are provided at both end portions of the beam-like member 9 a. The pair of telescopic support portions 13c, 13d are provided at both end portions of the beam-like member 9 b. That is, the support member 9 includes two pairs of telescopic supports 13a, 13b, 13c, 13 d.
An opening is provided in a wall of the hoistway 1, and the telescopic support portions 13a to 13d can be inserted into the opening when extended. The extended telescopic support portions 13a to 13d are inserted into the opening, whereby the support member 9 is supported by the wall of the hoistway 1. The support member 9 may be supported by the wall of the hoistway 1 by any other structure, and for example, the support member 9 may be supported by the wall of the hoistway 1 by placing the extended telescopic support portions 13a to 13d on a convex portion provided on the wall of the hoistway 1.
The telescopic support 6 (fig. 1) of the machine room unit 4 can have the same structure as the telescopic support 13 of the support member 9. The machine room unit 4 is fixed to the wall of the hoistway 1 by means of a telescopic support 6.
When an operator who gets on the work platform 11 wants to move the support member 9 in the lifting direction of the car 2, the telescopic support portion 13 is shortened, and when the operator wants to support the support member 9 by the wall of the hoistway 1, the telescopic support portion 13 is extended. The operator can extend and retract the telescopic support portion 13 manually or by any means.
The support member 9 may comprise three or more beam-like members having a pair of telescopic supports 13. That is, the support member 9 may include three or more pairs of the telescopic supports 13. The pair of telescopic support portions 13 may be provided with beam-like members other than the beam- like members 9c and 9d in a direction (the left-right direction in fig. 2) in which the car guide rails 7a and 7b face each other, and may be provided at both ends of the beam-like members.
Further, the support member 9 has a pair of shoes 14 and a pair of emergency stops 15 on at least one beam-like member. The support member 9 shown in fig. 2 has a pair of guide shoes 14 and a pair of emergency stop portions 15 for the beam- like members 9c and 9d, respectively. A pair of guide shoes 14a, 14b and a pair of emergency stop portions 15a, 15b are provided on both end portions of the beam-like member 9 c. A pair of guide shoes 14c, 14d and a pair of emergency stop portions 15c, 15d are provided on both end portions of the beam-like member 9 d. That is, the support member 9 includes two pairs of shoes 14a, 14b, 14c, 14d and two pairs of emergency stops 15a, 15b, 15c, 15 d.
The guide shoe 14a is fitted to the car guide rail 7a, and the guide shoe 14b is fitted to the car guide rail 7 b. The guide shoe 14c is fitted to the counterweight guide rail 7c, and the guide shoe 14d is fitted to the counterweight guide rail 7 d.
The emergency stop portion 15a is provided on the car guide rail 7a, and the emergency stop portion 15b is provided on the car guide rail 7 b. The emergency stop portion 15c is provided on the counterweight guide rail 7c, and the emergency stop portion 15d is provided on the counterweight guide rail 7 d.
When the construction elevator apparatus of the present embodiment is normally operated, i.e., the car 2 is raised and lowered, the machine room unit 4 is fixed to the wall of the hoistway 1 by the telescopic support portion 6. During this period, the worker who performs the elevator installation works gets on the work platform 11 to perform the installation work of the guide rail 7 and the equipment (not shown) in the hoistway 1. Further, in order to move the machine room unit 4 upward, the operator moves the support member 9, which supports the machine room unit 4 suspended therefrom, upward.
When the operator shortens the telescopic support portion 13 and moves the support member 9 upward, the guide shoes 14a and 14b are guided by the car guide rails 7a and 7b, respectively, and the guide shoes 14c and 14d are guided by the counterweight guide rails 7c and 7d, respectively, and move upward. Therefore, the support member 9 can be guided by the guide rail 7 through the guide shoe 14 and safely vertically moved with the direction kept constant.
Further, in the construction elevator apparatus of the present embodiment, when the support member 9 falls due to some cause while the support member 9 is moving, the emergency stop portion 15 can prevent the fall of the support member 9, and safety can be further improved.
Fig. 4 is a view showing the guide shoe 14 and the emergency stop portion 15 provided in the support member 9, and is a view when the support member 9 is stationary.
The guide shoe 14 is fitted to the guide rail 7 as described above.
The emergency stop portion 15 includes a pair of wedges 21, rollers 22, and wedge guides 24 that face each other across the guide rail 7. The wedge 21 is a wedge member movable in the elevating direction of the car 2 with respect to the support member 9, and is pulled up by a wedge pulling-up portion, not shown. The wedge-shaped pull-up part may be constituted by, for example, a pull-up rod operated by an operator riding on the work platform 11. The roller 22 and the wedge guide 24 are guide members that guide movement of the wedge 21 in the lifting direction of the car 2, and are fixed to the support member 9. The wedge guide 24 is a plate-like member that fits into a cutout provided in the wedge 21. The wedge 21 is movable upward relative to the roller 22 and the wedge guide 24.
When the pair of wedges 21 is pulled up by the wedge pull-up portion, it is guided by the rollers 22 and the wedge guides 24, and can move upward and in a direction approaching the guide rail 7 due to the wedge shape, so that the guide rail 7 can be nipped.
Fig. 5 is a view showing the guide shoe 14 and the emergency stop portion 15 provided in the support member 9, and is a view when the support member 9 moves upward.
When the operator wants to move the support member 9 upward, the operator pulls up the wedge 21 by the wedge pulling-up portion to bring the wedge 21 into contact with the rail 7, and moves the support member 9 while keeping the wedge 21 in contact with the rail 7. That is, when the support member 9 moves upward, the wedge 21 comes into contact with the guide rail 7. However, the wedge 21 is simply in contact with the guide rail 7 without clamping the guide rail 7 with a strong force to enable the movement of the support member 9.
When the support member 9 falls down for some reason during the upward movement, the wedge 21 contacts the guide rail 7, so that the downward movement is prevented by the frictional force between the wedge and the guide rail 7, and the roller 22 and the wedge guide 24 move downward. Then, the wedges 21 move upward relative to the rollers 22 and the wedge guides 24, and are guided by the rollers 22 and the wedge guides 24 to nip the guide rail 7 with a strong force (in fig. 5, the pair of wedges 21 further approach the guide rail 7). When the support member 9 falls, the wedges 21 thus quickly grip the guide rail 7 firmly, so that the support member 9 stops falling.
As described above, in the construction elevator apparatus according to the present embodiment, the emergency stop portion 15 can prevent the support member 9 from falling, and the support member 9 can be safely moved upward.
Further, in the construction elevator apparatus of the present embodiment, when the machine room unit 4 is moved, the load applied from the support member 9 to the building (the wall of the hoistway 1) can be reduced, and the load applied to the building that supports the support member 9 can be reduced. In a high-rise building, the construction elevator apparatus is large in size, and the machine room unit 4, the car 2, and the like supported by the support member 9 have a large weight. Therefore, when moving the machine room unit 4, if the support member 9 is supported by the building only by the telescopic support portion 13, the load applied from the support member 9 to the building is large, and the load on the building supporting the support member 9 is large.
As described above, the machine room unit 4 is suspended from the support member 9 by the machine room unit crane 8, and is movable in the lifting direction of the car 2 by the machine room unit crane 8.
When moving the machine room unit 4 upward, the operator pulls up the wedge 21 of the emergency stop portion 15 of the support member 9 by the wedge pulling-up portion until the wedge 21 grips the guide rail 7 with a strong force. Then, the wedges 21 firmly grip the rail 7 (in fig. 5, the pair of wedges 21 further approach the rail 7). When the machine room unit 4 moves upward, the support member 9 is fixed to the guide rail 7 by sandwiching the guide rail 7 with the pair of wedges 21 and holding the guide rail 7, thereby supporting the weight of the machine room unit 4, the car 2, and the like. When the support member 9 is fixed to the guide rail 7, the guide rail 7 can bear a part of the load applied to the support member 9.
In the construction elevator apparatus of the present embodiment, when the room unit 4 moves upward, the support member 9 can be supported by the building and the guide rail 7, and therefore, the load applied to the building from the support member 9 can be reduced, and the load on the building can be reduced.
[ example 2]
A construction elevator apparatus according to embodiment 2 of the present invention will be described. The construction elevator apparatus of the present embodiment has the same configuration as the construction elevator apparatus of embodiment 1, but the positions of the counterweight 3 and the counterweight guide rails 7c and 7d and the configuration of the support member 9 are different from those of the construction elevator apparatus of embodiment 1. The following mainly describes differences between the construction elevator apparatus of the present embodiment and the construction elevator apparatus of embodiment 1.
Fig. 3 is a plan view showing a support member 9 of a construction elevator apparatus according to embodiment 2 of the present invention. In the construction elevator apparatus of the present embodiment, the directions in which the car guide rails 7a and 7b face each other are different from the directions in which the counterweight guide rails 7c and 7d face each other, and the directions are orthogonal to each other.
The support member 9 has a pair of shoes 14a, 14b and a pair of emergency stop portions 15a, 15b only on the beam-like member 9 c. A pair of guide shoes 14a, 14b and a pair of emergency stop portions 15a, 15b are provided on both end portions of the beam-like member 9 c. That is, the support member 9 includes a pair of guide shoes 14a and 14b fitted only to the car guide rails 7a and 7b, and a pair of emergency stop portions 15a and 15b provided only on the car guide rails 7a and 7 b.
In the construction elevator apparatus of the present embodiment, when the support member 9 moves upward, the support member 9 is guided only by the car guide rails 7a and 7 b. The wedges 21 only grip the car guide rails 7a, 7b when the support member 9 is dropped and when the machine room unit 4 is moved upward.
As will be briefly described below, the construction elevator apparatus according to the present embodiment can obtain the same effects as those of the construction elevator apparatus according to embodiment 1.
When the support member 9 is moved upward, the guide shoes 14a and 14b are guided by the car guide rails 7a and 7b, respectively, and move upward. Therefore, the support member 9 can be guided by the car guide rails 7a, 7b and safely moved vertically with the direction kept constant.
When the support member 9 falls for some reason during the upward movement, the wedges 21 of the emergency stop portion 15 of the support member 9 grip and firmly hold the car guide rails 7a, 7b with a strong force, thereby stopping the falling of the support member 9. Therefore, the emergency stop portion 15 can prevent the support member 9 from falling down, and can move the support member 9 upward more safely.
When the machine room unit 4 moves upward, the wedges 21 of the emergency stop portion 15 of the support member 9 firmly grip the car guide rails 7a, 7b, and the support member 9 is fixed to the car guide rails 7a, 7 b. Therefore, the support member 9 can be supported by the car guide rails 7a and 7b, the load applied from the support member 9 to the building can be reduced, and the load on the building can be reduced.
The support member 9 may include a pair of guide shoes that are fitted only to the counterweight guide rails 7c and 7d, and a pair of emergency stop portions provided only on the counterweight guide rails 7c and 7 d. In the construction elevator apparatus having this configuration, the wedge 21 holds only the counterweight guide rails 7c and 7d when the support member 9 moves upward and when the support member 9 drops and the machine room unit 4 moves upward.
The present invention is not limited to the above-described embodiments, and various modifications are also included. For example, the above-described embodiments are described in detail for the purpose of illustrating the present invention, and the present invention is not limited to having all the structures described. In addition, a part of the structure of a certain embodiment may be replaced with the structure of another embodiment. In addition, the structures of other embodiments may be added to the structure of a certain embodiment. Further, a part of the configuration of each embodiment may be deleted, or another configuration may be added or replaced.
