Description

Circulating elevator system {One-way Circulating Elevator System}

The present invention relates to an elevator system, and more specifically, to build a system of two types of rack mast type elevator system having a self-propelled elevating cage (cage), but the lifting device and the horizontal movement on the bottom of the elevating cage bottom By mounting a device (traverse device) together, the two lifting passages are connected to each other to form a horizontal passage through which the cage can move, so that each lifting passage is dedicated to one function of raising or lowering, and the upper and lower horizontal passages In general, the present invention relates to a circular elevator system that allows a plurality of cages to pass in one direction.

The usefulness of elevators, one of the many useful inventions that made modern urban civilization possible, is incontrovertible, but from a more analytical point of view, there is no problem that needs to be improved. Only one elevator is installed in the aisle to perform the lifting and lowering operation alone, so the space efficiency and economic efficiency of the entire building are inferior, and if you miss the elevator due to slight parallax, you have to wait a long time until the elevator comes back. There was this. In particular, the higher the urban buildings, the more serious these inconveniences were. In order to solve such inconveniences, several elevators were installed and installed. However, the high cost and low efficiency problems of the conventional elevator system were essentially solved. In recent years, in order to solve the problems of the conventional elevator system, researches on the basic concept of the circulation elevator system have been actively conducted in industrialized countries such as the United States and Japan, and some reactions have been academically or patented. Technically perfect and economically reliable, a system suitable for commercialization has not yet emerged.

In order to solve this technical problem, the present invention is to build and erect two rack mast type elevator system in which the lifting cage is lifted by the interaction of the rack mast and the lifting pinion, the bottom of the lifting cage with the horizontal lifting device (Elevating device) is installed, and the elevating passages are provided on the upper and lower portions of the two lifting passages so as to form a transverse passage capable of horizontal movement of the cage by the transverse apparatus. Its purpose is to provide a revolving elevator system that can be used by one or more cages as a whole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the overall configuration and operating principle of the present invention and the structure and function of each component will be described in detail with reference to the accompanying drawings. FIG. 1 schematically shows the overall appearance of a circulating elevator system 100 according to the present invention. As a three-dimensional perspective view expressed in the form of a three-dimensional perspective view, the configuration of the overall system will be divided into four parts for easier understanding. The first part is a lifting passage and a transverse passage in which the lifting cages 3-1 to 3-4 are circulated. It is a steel structure of a type built by combining two lifting passages of a type of rack mast (1) type elevator system. First, each hoistway is a structure in which a rack (2) is attached to the opposite inner surface of the H-beam, which is erected in four corners, as shown in the drawing, and the pinion (11) of the hoist mounted on the bottom of the hoisting cage (3) In engagement, the lifting cages 3-1 to 3-4 serve as vertical passages for raising or lowering. Next, the transverse passages install transverse rail beams (4, 4 ') at the bottom of the elevating cage so that the cages (3-1) to (3-4) can move horizontally in the upper and lower portions of the elevating passage. The transverse wheels 12, which project slightly outwardly, can be moved horizontally on the rails. The upper rail beam 4 has a rail cutting portion 7 to enable the lifting of the protruding traverse wheels. As shown in the figure, four places are formed in both passages, and the rail cutting portion as shown in FIG. 4A in order to allow the traversing wheel 12 which has risen through the cutting portion 7 to traverse again and move to the neighboring lifting passage. The opening and closing device 20 is required, and the inner blocking plate 5 of the rail beam having the rail cutting part opening and closing device 20 installed therein becomes the outer wall surface of the shuttle 21 installation space and at the same time the rail when the transverse wheel is moved. Guy to prevent departure The upper rail is protruded slightly so as to have a rail function. The lower rail beam 4 'does not need the rail cutting portion 7, and in the case of a high-rise building of 20 or more floors, it is roughly required for smooth operation of the entire elevator system. It is preferable to install a horizontal moving passage in the middle of each of the ten floors, and the structure of the intermediate horizontal moving passage should be the same as that of the upper end. The second part includes the lifting cages 3-1 to 3-4 and It is a lifting device and a transverse device installed at the bottom. In the figure, four lift cages are being operated, but more cages can be installed if necessary, and the structure of the outer door 8 that enters and exits the elevator from each floor of the building, the lift room, and the inner door that is the door ( The structure of 9) is similar to the existing elevator, and there is no problem even if it is processed by the known technology related thereto. One of the original parts of the present invention, the elevating device and the transverse device will be described in more detail with reference to Fig. 2. The third part includes the rail cutting part opening and closing device 20 as described above. It relates to mechanical and structural aids associated with movement. Among them, since the rail cutting part opening and closing device 20 is one of the important partial systems providing organicity to the entire system of the present invention, it will be described in more detail with reference to FIGS. 4A to 4D and FIG. 5. On the other hand, the pinion guide rail (6) is installed as shown in Figures 1 and 2b to ensure the recombination of the pinion and the rack during the horizontal movement of the lifting pinion, the horizontal movement as the teeth of the lifting pinion and rack are engaged with each other. To this end, a height about the radius of the elevating pinion 11 above the rail beam, more precisely, the height at which the transverse wheel 12 is engaged with the elevating pinion when the transverse wheel 12 is ready to move horizontally on the rail beams 4 and 4 '. It is a device that ensures separation and reassembly with the rack by installing a guide rail (6) of the elevating pinion to connect the teeth of the rack located in the horizontally connected to the teeth of the same height located on the moving line horizontally. In addition, a slight cutting area should be formed in the rack mast positioned in the middle of both passages to allow the movement of the protruding transverse wheels 12 and to install the guide rails 6 of the elevating pinion. The fourth part is for the mobile outlet subsystem 40 and its components related to the supply of power required for the operation of the entire system. First, the overall configuration is shown in FIG. 1, and the main components are described in more detail in FIG. I will explain in detail. Since several cages are a kind of box-type circulation system, ascending and descending outlets must be installed as many as the number of cages, respectively. The configuration of one set of mobile outlet sub-systems can be connected to the outlet 41 and connected thereto. It is coupled to the outlet 41 while forming a very long oval ring between the electric wire 45, the drive reel and the electric motor 42 installed at the bottom of the elevating passageway, the interlocking pulley 43 installed at the top of the elevating passageway, and the drive reel and the interlocking pulley. The wire 44 for direct movement and the winding drum 46 of the wire are arranged. For the sake of understanding, in the drawing, the drive motor and the like are drawn slightly larger than the overall relative dimensions, so that the exterior surface is filled with four sets of movable outlets. In practice, a small electric motor suitable only for driving the outlet, the electric wire and the wire 44 is used. 2A is a three-dimensional perspective view of a self-propelled hoisting device and a transverse device formed on the bottom of the elevating cage 3, wherein the elevating device meshes with the rack mast 1 first. An elevating pinion 11 to raise or lower (3-1) to (3-4), and an electric motor 13 to transmit a driving force to the pinion 11 (this is preferably a geared motor to which a braking force is applied). And four sets of belt reels 14, which are intermediate transmission devices of the driving force, and a belt 15 and a drive shaft 16 of the pinion are formed in the structure as shown in the drawing. On the other hand, the traverse device includes four traverse wheels 12; Among them, a pair of drive wheels to which driving force is directly transmitted is connected to a shaft 16 ', and an electric motor 17 and a worm gear 18 to transmit driving force to the shaft are connected, and a storage battery 19 is provided together. . The two wheels to which the driving force is not directly transmitted serve as the auxiliary wheels interlocked with each other, and the storage battery is an essential equipment because power is cut off when the horizontal movement of the cage starts. FIG. As a plan view, the arrangement state of the elevating device and the transverse device is shown. Particular attention is given to a wiring diagram of electricity introduced into the drive motor and two plugs arranged in parallel. By installing two plugs on the left and right sides of each cage in parallel, the cage on the left is connected to the outlet on the left with the plug on the left and the cage is separated during the horizontal movement. 3 is a side view illustrating the principle that the pinion 11 of the elevating device is engaged with the rack mast 11 to perform the lifting operation. When the central electric motor is rotated clockwise, the left pinion also rotates clockwise. The lifting cage is pulled down, the right pinion rotates counterclockwise and the lifting cage is also pulled down. The left belt is the result of roping in parallel and the right belt is the X-rope, and as the motor rotates counterclockwise, the lifting cage is raised as well. FIGS. 4A and 4B show the upper rail beam of FIG. 4) is a plan view of the rail cutting part opening and closing device 20 for elevating and extending the transverse wheel 12. Fig. 4A shows a state in which the rail cutting part is open, and Fig. 4B shows a state in which the rail cutting part is closed. It shows the situation where two lifting passages are installed in a row and function as a set of horizontal movement passages. In particular, the size of the shuttle 21 is slightly longer than that of the cutting portion 7 and is located in the immediate vicinity so that the cutting portion can be opened and closed. Opening and closing operation of the shuttle 21 is mounted between the shuttle projection pin 230 formed horizontally on the shuttle 230 and the support pin 24 formed perpendicular to the rail beam as shown in FIG. 4C, and the shuttle projection pin ( The other end of the wire 35 connected together to the cylinder 23 is connected to the cylinder, the shuttle is reciprocating by the operation of the cylinder, that is, when the rod of the cylinder 31 shown in Fig. 5 is extended, the shuttle 21 moves to the outside to open the rail cutting portion 7, and when the rod of the cylinder 31 is retracted, the shuttle 21 is gathered in a closed state and the rail cutting portion 7 is closed. The spring (22) is then the opposite of the cylinder rod It is a device that reliably completes the opening and closing operation of the shuttle while acting as a force in a direction. Fig. 4C expresses the structure and shape of the shuttle 21 for opening and closing the rail cutting part, and three rectangular rectangular steel pipes are shown in the drawing. As described above, when the rail cutting portion 7 is closed by connecting with the flat iron, the rail can play the role of the rail, and when opened, the transverse wheel 12 can be lifted and lifted. Shuttle protrusion pins 23 vertically attached to the inside of the rail beams 4 and 4 'about the shuttle 21, support pins 24 protruding horizontally to the shuttle, and installed between these two pins. The spring 22 and the wire 35 fastened to the fixing pin of the spring are connected to the pneumatic cylinder set 30. Fig. 4D shows the overall arrangement of the rail cutout opening 20 and the pneumatic cylinder set 30. In three-dimensional perspective to express the state The shuttles of both passages are installed symmetrically with each other, as shown in the figure, so that it is economical and accurate in operation to be connected to one pneumatic cylinder. The transverse wheel 12 can be passed over it, thereby expressing the situation. FIG. 5 shows a pneumatic pressure supplying a driving force that enables the reciprocating movement of the shuttle 21 in the rail cutting part opening and closing device 20 of FIG. As a three-dimensional perspective view of the enlarged cylinder set 30, it is difficult to secure a space for installing the set consisting of the control valve 32 and the air compressor 34 in addition to the cylinder 31, but the weight and reciprocation of the shuttle 21 In terms of stroke distance (about 15 cm), etc., it is determined that the air compressor 34 may not be a problem because the air compressor 34 may be a small size to be installed in the pillar beam. As can be seen in FIG. 5, a pair of pulleys 33 are provided for smooth operation of the wires 35 connected between the cylinder 31 rods installed vertically and the two symmetrical shuttles 21 mounted horizontally. In Fig. 6, the drive reel and the motor 42 installed at the lower end of the elevating passageway, the interlocking pulley 43 at the upper end, and the outlet 41 and the plug 49 are installed. The support plate 47 and the hanger 48, which are devices for assisting the coupling and disengagement, are shown. The pulley and the reel must be a pair of pulleys due to the structure of the wire, and the support plate is normally inserted in order to insert the plug into an outlet fixed to the wire. (47), and for the same reason there should be a hook to hold the outlet when the plug is pulled out.

In summary, the effects of the recirculating elevator system of the present invention described above, first, by installing a plurality of elevators in a set of two elevator system lifting passages will dramatically reconsider the space efficiency of the building (4 units 2 times, 6 times 3 times, 8 times 4 times, etc.) Most of the high-rise buildings that require the installation of elevators are mostly large buildings built on enormously expensive sites. Space value also has great economic value, so the economic effect of this system is indisputable. Second, the convenience of using the elevator is greatly improved. You don't have to wait for the elevator to go back and use the next one. In particular, in most business buildings, more efficient passenger transportation is possible when one-way passengers are concentrated up and down during commute. Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto. Many variations and modifications may be made within the scope of the claims. For example, the lift cages used in the present invention may be reduced for increased or reduced power as needed rather than four.
