[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-deck type construction elevator.

[0002]

2. Description of the Related Art Generally, an elevator installed in a building structure is of a rope drive type, and a carrier (car) is mounted on a rope which is wound and unwound by a drive device provided in a machine room at the top of a hoistway. (Including a) and a counterweight are connected and hung down to be lifted and lowered in a hoistway.

Recently, in order to increase the efficiency of raising and lowering personnel in this rope-driven elevator, a double-deck type elevator has been developed in which two cars arranged vertically are moved up and down so that the cars can reach two floors at the same time. Is being done. Conventionally, as a rope drive type double deck elevator, those shown in FIGS. 15 and 16 have been disclosed.

FIG. 15 is a front view showing a carrier used in a conventional rope-driven double-deck elevator, and FIG. 16 is a side view of the same. This is 2 inside the carrier frame 1.
The cars 2 and 3 of the table are arranged vertically, the upper car 2 is fixedly supported by the carrier frame 1, and the lower car 3 is carried.
Is supported so that it can move up and down, and both cars 2 and 3 are connected by an up-and-down moving device 4.
Move up and down. The carrier frame 1 is hung on a rope (not shown) so that it can be raised and lowered along a guide rail (not shown). When the carrier frame 1 is moved up and down, both cars 2 and 3 are moved up and down together. When one of the upper or lower cars 2 and 3 reaches the destination floor and stops the carrier frame, the other car reaches the upper or lower floor of the destination floor. The car 3 is moved up and down by the up-and-down moving device 4 to adjust the distance between the upper and lower cars 2 and 3 according to the size of the distance between the destination floor and the adjacent floor.

On the other hand, a construction elevator used at a construction site for constructing a building structure is generally provided with a rack on a mast, and a carrier is equipped with a pinion meshing with the rack and a rotary drive device for rotationally driving the pinion. hand,
A self-propelled elevator is used in which the carrier is driven up and down by itself. Recently, in this self-propelled construction elevator, adoption of a double-deck type elevator is being considered for efficient construction work.

[0006]

Therefore, in adopting the double deck elevator in the self-propelled construction elevator, it is conceivable to adopt the double deck elevator used in the above-mentioned rope drive type elevator. However, in this case, there are the following problems, and therefore, there is a demand for the development of a double deck elevator having a structure suitable for a self-propelled construction elevator.

The above-mentioned problems are described below.
First, the work elevator requires repeated assembly work to extend the lift according to the progress of construction work. But,
In the rope-driven double-deck elevator, it was difficult to assemble and construct the lifting head for the following reasons.

First, since the rope-driven double-deck elevator has a structure in which the vertical force of all the elevators is received by the support beam provided at the top of the hoistway, the structure of the building to which the support beam is to be attached at each extension of the lift is Beams and columns need to be reinforced.

Secondly, since the rotary drive unit and the control panel are provided in the machine room at the top of the hoistway, the top of the hoistway is closed, and the lift of the mast, guide rails, doors on each floor, etc. is extended. It is not possible to use a crane to suspend the structure required for the building from outside the building. In addition, since a large machine room must be lifted as a unit and moved to the upper floor, a lifting machine with an unnecessarily large lifting capacity must be installed and used.

Thirdly, in the rope-driven double-deck elevator, the carrier and the counter eight are connected by a wire rope through the drive sheave, and the tension of both sides causes the friction of the drive sheave and the hoisting wire rope to hoist the wire rope. Since the structure lowers and raises and lowers, when the counterweight is cut off, the carrier cannot be lifted up and down independently.Each time the assembly work is performed by extending the lifting height, the carrier is lifted up and down independently with the counterweight cut off. However, the carrier must be used as a work stage for assembling, but the carrier cannot be moved up and down by itself, and safe and quick assembly work cannot be performed. Also, when the wire rope is extended, the wire rope cannot be extended unless the carrier is hoisted by another lifting machine and just below the support beam, which is a dangerous and difficult task.

Fourth, in the rope-driven double-deck elevator, many wire ropes such as hoisting wire ropes and wire ropes of speed governors have to be extended and tension adjusted, which requires a great deal of assembly work and labor. Become.

Next, in the case of an elevator for construction, when the construction is completed, the carrier is diverted to other works one after another, but the carrier used for the conventional rope drive type double deck elevator is always a large integrated type. As a result, a large load remains, it is difficult to use in small construction with a small amount of transportation, the operating rate is significantly reduced, and it is difficult to disassemble and carry out in a narrow hoistway when the construction is completed. For this reason, it is difficult to use the carrier alone as another elevator for construction work.

As described above, when the conventional rope-driven double-deck elevator is adopted for the construction elevator, it is difficult to extend the lifting height and it is difficult to convert the carrier to another construction elevator. It was Therefore, it has been conventionally desired to develop a double-deck elevator that can be easily assembled and constructed for a lift of a construction elevator and can be transferred to another construction elevator.

The present invention has been made in view of the above circumstances, and provides a double-deck elevator type construction elevator which is easy to extend and assemble and construct a lift, and which can transfer a carrier to another construction elevator. To aim.

Reference numeral 44 designates a basket on which personnel and materials are placed and which is supported by the rollers 49 provided on both sides in a vertically movable manner by rotating the rollers 49 on both sides of the carrier frame 41. The carrier frame 42 or the car 44 is equipped with a device such as a motor speed reducer 45 and an automatic fall prevention device 46 that is necessary for lifting. The motor reducer 45 is equipped with a pinion 47 that meshes with the rack 12 of the mast 11. As a result, when the motor speed reducer 45 rotationally drives the pinion 47, the pinion 47 obtains a lifting force and can lift the entire carrier 41. In addition,
The car 44 is provided with an operation panel 48 having destination buttons 48a arranged side by side, and the destination button 48a has a destination floor of either an odd floor or an even floor. For example, when the upper carrier 31 indicates the odd floor, the lower carrier 41 indicates the even floor.

As shown in FIG. 6, the carrier frame 32 of the upper carrier 31 and the carrier frame 42 of the upper carrier 41 are foldably and detachably connected by a connecting means. What is used in this embodiment is an example of the connecting means, and the lower ends of the left and right side portions of the carrier frame 32 of the upper carrier 31 and the upper carrier 41 facing them are used.
A pair of connecting plates 51 are respectively provided at the upper and left ends of the carrier frame 42, and both ends of the pair of connecting plates 51 are pivotally supported on the carrier frames 32, 42 by pins 52, 53. The pins 52 and 53 are removably inserted into the carrier frames 32 and 42. Thereby, the carrier frame 32 of the upper carrier 31 and the upper carrier 4
No. 1 carrier frame 42 is detachably connected, and each carrier frame 32.42 is removed by removing the pins 52, 53.
Can be disconnected.

Further, a car 34 fixedly supported by the upper carrying device 31 and a car 44 provided on the lower carrying device 41 so as to be movable up and down are two sets of electric motors, which are one form of a vertical moving device. They are connected by a cylinder device 61. As shown in FIGS. 7 and 8, the electric cylinder device 61 is inserted into a cylinder 62, a piston rod 63 that is linearly movable inside the cylinder 62 and has a tip protruding from the tip of the cylinder, and the cylinder 62. Placed bearing 6
9, a feed screw 64 and a cylinder 62 that are rotatably supported.
Is screwed into the feed screw 64 and the piston rod 63
It is provided with a slider 65 fixedly mounted on the cylinder 65 so as to be linearly movable, an electric motor 66 mounted on the cylinder 62, and a gear mechanism 67 for transmitting the rotation of the electric motor 66 to the feed screw 64.

The electric cylinder device 61 is vertically arranged between the car 34 of the upper carrying device 31 and the car 44 of the lower carrying device 41, and has a cylinder 62 having an electric motor 66.
A piston rod 6 which is pivotally and detachably connected to a fixture 68 provided on the bottom surface of the car 34 via a pin 68a so that the base end of the piston rod 6 protrudes from the tip of the cylinder 62.
The tip end of 3 is rotatably and detachably connected to a fixture 69 provided on the top surface of the car 44 via a pin 69a. The base end of the cylinder 62 and the attachment 68 are detachably connected to the tip of the piston rod 63 and the attachment 69. Therefore, by removing the pins 68a and 69a, the connection between the cars 34 and 44 can be released.

When the feed screw 64 is rotated by the rotational drive of the electric motor 66 via the gear mechanism 67, the slider 65 is converted into a linear motion to move the piston rod 63 along the cylinder 62 to the outside as shown in FIG. It moves forward toward the inside or moves backward toward the inside as shown in FIG. 7. As a result, the lower carriage 4 connected to the piston rod 63
The car 44 of 1 moves up and down along the carrier frame 42 to adjust the distance between the car 34 of the upper carrier 31 and the car 44 of the lower carrier 41. In addition, each carrier 31, 41
Is powered by a cable 76 from a power source (not shown) provided in the building.

Further, the carrier frame 3 of the upper carrier 31
2 is connected to one end of the wire rope 71. This wire rope 71 is a sheave 13 provided on the top of the mast 11.
The counter weights 72 and 73 are connected to the other end. As shown in FIGS. 9 and 10, the upper weight 72 and the lower carrier 41 corresponding to the upper carrier 31.
The lower weight 73 corresponding to is connected by a pin 74, and is provided with rollers 75 which come into contact with both sides of the mast 11 so as to be able to smoothly move up and down. Therefore, the carrier 21 moves up and down in balance with the counterweights 72 and 73.

Therefore, this construction elevator is equipped with the carrier 2
When the destination floor is instructed by operating the operation panel 36 provided on the car 34 of the carrier 31 or the operation panel 46 provided on the car 44 of the carrier 41 in FIG. 1, each of the floors B1 to B4 preliminarily input to the computer of the control panel 39. The electric cylinder device 61 is driven according to the height between the two, and the size of the space between the car 34 of the side carrier 31 and the car 44 of the lower carrier 41 is adjusted based on the destination floor. Then, the motor speed reducers 35, 45 of the respective transporters 31, 32 are driven to move up and down the transporters 31, 41, that is, the double-deck type transporter 21. As a result, the personnel and materials can be placed and transported on two carriers at a time, and the height between them can be adjusted to reach the two levels.

Further, in this construction elevator, as described above, the connection between the carrier frames 32 and 42 in the carrier 21 is released, the connections between the cars 34 and 44 are released, and the electric cylinder device 61 is removed to remove the upper side. The transporter 31 and the transporter 41 on the lower side can be separated and used as single-deck type transporters for construction elevators. That is, the upper transporter 31 is equipped with an operation panel 81 and a control panel 82 for single use as shown in FIG. 11, and the lower transporter 41 is used for individual use as shown in FIG. Equipped with 83 and control panel 84. In addition, the counter weight 72,
73 is also separated. Then, as shown in FIG. 11, the separated upper carrier 31 and weight 72 are mounted on the mast 11 and used, and as shown in FIG. 12, the separated lower carrier 41 and weight 73 are mounted on the mast 11. use. As a result, the double deck type carrier 2 is formed by connecting the respective carriers 21, 31.
The single-deck type elevator can be configured and used not only by using it as No. 1 but also by individually combining it with the mast as the carriers 31, 41 that can be driven independently of each other. That is, the double-deck type carrier 21 is self-propelled, and is a combination of self-propelled carriers 31 and 41 that can be used independently of each other.
This is a configuration that can be realized by detachably connecting the terminals 1 and 41.

FIG. 11 (a) is a front view showing the construction elevator, FIG. 11 (b) is the same side view, FIG. 12 (a) is a front view showing the construction elevator, and FIG. 12 (b) is the same side view. Is.

Such a construction elevator has the following features. First, an elevator using a double-deck type transporter 21 having a structure in which two transporters 31 and 41 that are self-propelled by a rack and pinion drive system are arranged on the upper and lower sides and detachably connected to each other are provided on the mast 11. For use as a construction elevator, there are the following advantages as compared with the case of using the conventional rope-driven double-deck elevator shown in FIGS. 14 and 15.

The first advantage is that the elevator uses the rack-and-pinion drive type double-deck type carrier 21 when performing the assembling work in which the lifting height is lengthened according to the progress of the construction work. For this reason, the extension and assembling work of the lift and the construction are very easy.

That is, since the vertical force of all the elevators is received by the foundation A on the ground via the mast 11, no beams are required, and it is not necessary to reinforce the beams and columns of the building. Each of the carry units 31 and 41 has a drive motor reducer 3
Since there are 5, 45, operation panels 38, 48 and control panel 39, there are no obstacles at the top of the hoistway and it is necessary to extend the lift of the door of the mast 11 and each floor B1 to B4 of the building. Various members can be easily suspended from the outside of the building by using a crane. For the same reason, the machine room does not need a machine room at the top of the mast 11 and does not require a special large lifting machine to lift the structure required to extend the lift of the elevator. A lifting machine with a suitable lifting capacity can be installed and used.) Further, since the transporter 21 (transporters 31, 41) can be lifted and lowered independently by driving the drive motor speed reducers 35, 45 mounted on the transporter 21 (transporters 31, 41), the lift can be extended. Each time the assembling work is performed, the carrier 21 (carries 31, 41) is individually lifted up and down with the counterweights 72, 73 separated.
The top of the carrier 21 (carries 31, 41) can be used as a work stage during assembly, and safe and quick assembly work can be performed. When the wire rope 71 is extended, the carrier can be independently moved up and down to the top of the hoistway to extend the wire rope 71, so that dangerous and difficult work can be avoided.

The second advantage is that the wire rope 71 only supports the counterweights 72 and 73.
The work of extending the wire rope 11 and the work of adjusting the tension become easy, and the time and labor for the work of assembling the hoistway can be greatly reduced.

Secondly, the transporter 21 (transporters 31, 41) is of the double-deck type in which the single-deck transporters 31, 41 described above are detachably connected, so that the rack and pinion drive system is adopted. The traveling construction elevator can be used as a double deck elevator. The self-propelled double-deck elevator for construction that employs the rack and pinion drive system has the following effects as compared with the single-deck elevator for construction. That is, the flat area of the temporary opening (including the temporary use part of the main elevator) as an elevator shaft is about half compared to the case where a single-deck elevator with the same loading capacity is used, so the entire temporary opening The area is reduced and the construction period can be shortened. Further, even in a relatively small construction site where a temporary opening as an elevator shaft or a plurality of temporary openings cannot be provided, an elevator having a large loading capacity can be installed in a small opening.
Since the number of times of stopping at each floor in order to raise and lower the (transporters 31, 41) and unload the personnel and the load is about half, the time required for the lifting work can be shortened and the speed can be increased.

Thirdly, since the cages 34 and 44 provided on the two single-deck type transporters 31 and 41 arranged on the upper and lower sides, respectively, can be adjusted in the vertical direction by the vertical moving device, during the construction work. It is possible to adjust the distance between the two cars 34, 44 in the vertical direction by adjusting and controlling the drive amount of the vertical movement device according to the floor height (height between floors) of the building structure.

Fourthly, the double-deck type carrier 21 has two single-deck type carriers 31, 41 arranged on the upper and lower sides detachably connected by the connecting means and the vertical moving device (electric cylinder device 61). , While the elevator is being applied to the construction, the double-deck type carrier 21 is separated from each other as necessary, and two independent single type carriers 3 are provided.
It is possible to use as the double deck type carrier 21 by connecting the two separated single type carriers 31 and 41 to each other. When not used as an elevator equipped with the double-deck type transporter 21, each of them can be independently used as a construction elevator equipped with the single-deck type transporter 31.41 with a small (half) load capacity, so that the operating rate is high. Is greatly increased and the economic effect is high. When the double deck type carrier 21 is separated from each other and used as two independent single type carriers 31 and 41, the carrier can be lifted and lowered independently even if the counterweights 72 and 73 are separated. The accompanying lift extension work can be performed safely and quickly by using the carrier on the work stage.

Fifth, two single-deck type carriers 3
Since the double-deck type transporter 21 is configured by connecting two units 1 and 41, it is possible to easily disassemble and carry in a narrow space after the completion of the construction work.

The present invention is not limited to the above-mentioned embodiment and can be carried out in various modified forms. The vertical moving device that connects the cage of the upper carrier and the cage of the lower carrier to adjust the distance between the two is not limited to the above-described electric cylinder device, and other types can be used.

For example, FIG. 13A is a side view of the carrier 21, and the same parts as those in FIG. 2 have the same reference numerals. In this embodiment, a pan tag graph device 101 as a vertically moving device connects the car 34 of the upper carrying device 31 and the car 44 of the lower carrying device 41. The pantograph device 101 is a hydraulic device 1.
The hydraulic cylinder 102 driven by 03 moves up and down. Both ends of the pantograph device 101 are pivotally attached and detachably connected to the car 31 of the upper carriage 31 and the car 44 of the lower carriage 41, and the car 3 is moved vertically.

According to the construction elevator of the first aspect of the present invention, two single-deck type transporters, which are self-propelled by the rack and pinion drive system, are arranged on the upper and lower sides and are detachably connected to each other and provided on the mast. In order to use an elevator using a double-deck type transporter having a different structure as a construction elevator, when extending the lift according to the progress of the construction work, the extension assembly work and construction become very easy. Further, since the wire rope only supports the counterweight, extension work and tension adjustment work of the wire rope are facilitated, and the time and labor for assembling the hoistway can be greatly reduced.

A self-propelled construction elevator that employs a rack and pinion drive system can be used as a double-deck elevator, and a self-propelled construction double-deck elevator that employs a rack and pinion drive system can be used. Since the flat area of the temporary opening as the elevator shaft is about half that in the case of using a single deck type elevator having the same loading capacity, the total temporary opening area is reduced and the construction period can be shortened. In addition, even in a relatively small construction site where temporary openings as elevator shuffs or multiple temporary openings cannot be provided, an elevator with a large loading capacity can be installed in a small opening. Since the number of stoppages on each floor is reduced to about half, the time required for lifting work can be shortened and the speed can be increased.

Further, since the cages provided on the two carriers arranged on the upper and lower sides are connected by the vertically moving device so that the vertical distance can be adjusted, the floor height of the building structure under construction can be adjusted. It is possible to adjust the drive amount of the vertical moving device according to the above and control it to adjust the distance between the two cars in the vertical direction.

According to the second aspect of the present invention, since the cages provided respectively on the two upper and lower carriers are connected by the vertical movement device so that the vertical gap can be adjusted, the building structure under construction The distance between the two cars in the vertical direction can be adjusted by adjusting and controlling the drive amount of the vertical moving device according to the size of the floor height (height between floors) of the object. In addition, since the two carriers arranged on the upper and lower sides are detachably connected by the connecting member and the vertical movement device, the double deck type carriers can be connected to each other as necessary while the elevator is being applied to the construction. It can be separated and used as two independent single type carriers, and two separated single type carriers can be connected to each other and used as a double deck type carrier. In addition, when not used as an elevator equipped with a double-deck carrier, each can be independently used as a construction elevator equipped with a single-deck carrier with a small load, resulting in a significant increase in operating rate and economic benefits. high. When the double deck type carrier is separated from each other and used as two independent single type carriers, even if the counterweights are separated, the carrier can be lifted and lowered independently. Can be used as a work stage to perform safely and quickly. Since the double-deck type transporter is configured by connecting two single-deck type transporters in this way, it is possible to easily dismantle and carry it in a narrow space after the completion of the construction work. That is, not only can each of the carriers be connected to be used as a double-deck type carrier, but a single-deck elevator can be configured and used by individually combining the masts as carriers that can be driven independently of each other. That is, the double-deck type carrier can be realized by being self-propelled, by combining single-deck type self-propelled carriers which can be used independently of each other, and by detachably connecting these carriers. It is a composition.

Therefore, according to the present invention, it is possible to obtain a double-deck elevator type construction elevator which is easy to assemble and construct the extension of the lift and which can transfer the carrier to another construction elevator.
