Description

  The present invention relates to an elevator facility in which a hydraulic elevator is renewed to a rope elevator using a hoisting machine.

  There are two types of elevators: rope type using a hoisting machine and hydraulic type. Conventionally, a hydraulic elevator (for example, refer to Patent Document 1) that does not require a machine room above a hoistway has been used in a low-rise apartment with a relatively small number of floors. In this hydraulic elevator, a car installed in a hoistway so as to be able to be raised and lowered is driven up and down by a hydraulic jack erected in a space between one side surface of the car and the inner wall of the hoistway. This hydraulic jack has a plunger that moves up and down by hydraulic pressure, a sheave is provided at the tip of the plunger, and a rope is wound around the sheave. One end of this rope is connected to the car side, and the other end is connected to the lower base of the hydraulic jack, and when the plunger of the hydraulic jack moves up and down, the rope wrapped around the sheave at the tip of the rope The car is driven up and down through.

  The hydraulic elevator having such a configuration has been widely used in condominiums and the like in which the right of sunshine with a relatively low-rise structure is a problem because the machine room does not protrude above the hoistway. In other words, before the rise of machine room-less rope type elevators, as the elevator equipment below the 8th and 9th floors, the market shipment rate was equivalent to that of the rope type. However, after the emergence of a machine room-less rope type elevator, the machine room-less rope type elevator, which is easy to maintain and environmentally friendly, has become the main force, and the hydraulic elevator is part of special elevators for luggage and loading.仕 様 Applicable to specifications with large excess weight.

  This hydraulic elevator has been shipped since 1990 to 1995, and those that have been operating since that time have been subject to renewal in terms of useful life. In this renewal, for the above-mentioned reasons, the renewal is mostly renewed from a hydraulic type to a machine room-less rope type having a hoisting machine.

  As a renewal method in this case, it is conceivable to completely remove hoistway equipment, supplies and a car and renew it to a rope type elevator. In the renewal by this complete removal, the car and the guide rail are disassembled, so that a sufficient space can be secured in the hoistway, and equipment can be carried out and installed easily. However, among these, the hydraulic jack has a long shape, so that it is necessary to divide and cut it and remove it from the hoistway to the hall for removal. For this reason, much time and labor are required.

  In addition to this complete removal method, there are various types of menus that meet the customer's requirements, such as a type that renews the control panel, a type that renews only the display device, which is a car or a design product, and leaves what can be used. Yes.

  Here, when the renewal of the hydraulic elevator renews the rope while leaving the car, removal of the hydraulic jack becomes a problem as described above. As a countermeasure to this problem, a method of renewing a rope type elevator while leaving a hydraulic jack has been studied.

JP-A-10-330060

  If the rope jack is renewed with the hydraulic jack remaining, the installation space for the hydraulic jack remains as it is. In other words, equipment that is newly required as a rope type, such as a counterweight, its guide rail, and a hoisting machine, must be installed in a hoistway that is designed by installing a hydraulic system. Since the hydraulic system does not require a counterweight, the plunger and the rope have a simple configuration. This is also the reason why the space in the hoistway is narrow.

  In a standard nine-seater back plunger type (with a hydraulic jack installed between the back of the car and the inner wall of the hoistway), the hoistway inner method is about 2200 depth x about 1500 mm wide Yes, the outside of the car has a depth of about 1700 × width of about 1100 mm, and there is only a device installation space of 400 mm in the depth and 200 to 250 mm in the lateral direction. In the renewal of such a back plunger type hydraulic elevator, the device is arranged in the empty space in the part where the hydraulic jack is installed. In the case of the side plunger, since there is a space of about 500 mm in the lateral direction, the device is arranged in this area.

  In any case, after installing the hoisting machine stand and securing the space for the hoisting machine and the counterweight, other devices are arranged in the remaining space. As described above, the area where the equipment can be arranged is a space where the hydraulic jack remains, and the equipment is concentrated because the equipment is installed avoiding the hydraulic jack. Among these, the control panel that houses the equipment for controlling the rope system must also be newly installed in the hoistway because there is no machine room, and there is a problem that there is no installation space.

  The object of the present invention has been renewed by installing a control panel in a hoistway, which has been difficult to install by attaching a control panel using a remaining hydraulic jack or equipment attached thereto. The purpose is to provide elevator equipment.

In the elevator installation according to the present invention, a hydraulic jack is erected in a projection space from above between a side surface of a car installed in a hoistway so as to be able to be raised and lowered, and one end of the elevator hoistway. Wrap the middle part of the rope fixed to the inner bottom and the other end to the car side to the plunger sheave provided at the tip of the plunger of the hydraulic jack, and move the plunger up and down with the hydraulic jack Thus, the hydraulic elevator that lifts and lowers the car via the rope is renewed into a rope type elevator using a hoisting machine with the hydraulic jack remaining in the hoistway. Te, the both sides of the hydraulic jacks are installed a pair of plunger guide rails for guiding the vertical movement of the plunger, the plan A control panel for controlling the rope-type elevator after renewal is arranged in the space formed between the pair of plunger guide rails by lowering the lowermost position to the lowermost position, and brackets are attached to both sides of the control panel. And a pair of plunger guide rails which are left in the hoistway together with the hydraulic jack .

  In the present invention, a configuration may be adopted in which a horizontal base is integrally provided at the upper end portion of the plunger, and a control panel for controlling the rope-type elevator after the renewal is installed on the base.

  According to the present invention, since the control panel is attached using the hydraulic jack left in the boarding / exiting path, the plunger guide rail attached to this, the plunger, etc., the inside of the renewed narrow hoistway The control panel can also be installed at.

It is a disassembled perspective view explaining the attachment structure of the control panel in one embodiment same as the above. It is a front view explaining other embodiment of this invention. It is a perspective view explaining the process structure of the plunger in embodiment of FIG. It is a front view explaining further another embodiment of this invention.

  Hereinafter, an embodiment of an elevator installation according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a configuration in a hoistway of an elevator installation according to this embodiment, where (a) is a front view and (b) is a side view. In FIG. 1, in the hydraulic elevator, as described above, a projection space from above between one side surface (for example, the back surface) of a car (not shown) that is installed in the hoistway 11 so as to be movable up and down and the inner wall of the hoistway. A hydraulic jack 12 is erected inside. The hydraulic jack 12 has a plunger 13 that moves up and down by hydraulic pressure, and a plunger sheave 14 is provided at the tip thereof. During operation as a hydraulic elevator, an intermediate portion of a rope having one end fixed to the lower part in the hoistway is wound around the plunger sheave 14, and the other end is fixed to a hitch portion on a car side (not shown). Then, when the plunger 13 is moved up and down by the hydraulic jack 12, the car is driven up and down through a rope wound around the plunger sheave 14 provided at the tip thereof. When renewing a hydraulic elevator having such a configuration to a rope type elevator using a hoisting machine, the hydraulic jack 12 is long as described above, and therefore it takes a lot of time and labor to remove it. Cost. For this reason, the hydraulic jack 12 remains in the hoistway 11.

  The hydraulic jack 12 includes a pair of plunger guide rails 15 on both sides of the hydraulic jack 13 in order to guide the plunger 13 and the plunger sheave 14 at the tip thereof in the up-and-down direction when used as a hydraulic elevator. Is provided. The plunger guide rail 15 is also left in the hoistway 11 together with the hydraulic jack 12 at the time of renewal. Since the hydraulic jack 12 is not used after renewal to the rope type elevator, the oil is drained and the plunger 13 is lowered to the lowermost position as shown.

  When the plunger 13 is lowered, an unused space is generated between the pair of plunger guide rails 15 above the hydraulic jack 12. Therefore, a control panel 16 for controlling the rope-type elevator after the renewal is installed using a space generated between the pair of plunger guide rails 15 above the hydraulic jack 12. That is, the control panel 16 is disposed between the pair of plunger guide rails 15 in the hoistway 11, and both side portions of the control panel 16 are integrally attached to the plunger guide rails 15 via the brackets 17.

As described above, when the hydraulic elevator is renewed to the rope type elevator, the hydraulic jack 12, the plunger 13, and the plunger sheave 14 are left without being removed, thereby shortening the construction period. The remaining hydraulic jack 12 has its plunger 13 shortened, and the working oil inside the cylinder of the hydraulic jack 12 is extracted from the pipe. Plunger guide rails 15 are installed on both sides of the hydraulic jack 12 so as to guide the movement when the plunger sheave 14 is moved. Therefore, the control panel 16 is installed between the plunger guide rails 15 on the uppermost floor. .
Here, the control panel 16 usually has a uniform size and shape. On the other hand, since the dimension between the rails of the plunger guide rail 15 differs depending on the capacity of the hydraulic jack 12, it is preferable to use a bracket 22 for adjusting the interval as shown in FIG. That is, the plunger guide rail 15 has a T-shaped cross section, and a mounting hole 21 is provided in a T-shaped central leg portion which is a support surface for the side portion of the control panel 16. In order to adjust the mounting distance with the bracket 17 provided on the side of the control panel 16, the mounting distance between the plunger guide rails 15 is adjusted using the adjusting bracket 22.

  In the above configuration, when operated as a rope type elevator, the control panel 16 installed between the plunger guide rails 15 is not more than the outside dimension of the installation space of the hydraulic jack 12, and the depth dimension is about 100 mm. So there is a safe distance between the elevator and the elevator. The maintenance adjustment for the control panel 16 is performed by the operator holding it in the car. Since the control panel 16 is installed between the plunger guide rails 15 near the back of the car, Since the installation distance between the car position and the control panel 16 is close, workability is good. Further, if the control panel 16 can be installed between the plunger guide rails 15, the control panel 16 can be freely arranged with respect to the length direction of the plunger guide rails 15. To do.

  By arranging the control panel 16 between the existing plunger guide rails 15 in this way, the hydraulic jack 12 and the plunger guide rail 15 can be installed without being removed. Work can be shortened, and it is effective in shortening the renewal work period. Further, regarding the point that there are many restrictions on the arrangement space of the equipment, which is a problem of renewal in the hydraulic elevator, it is possible to save equipment by installing the control panel 16 in the space obtained by lowering the plunger 13.

  Next, the embodiment shown in FIGS. 3 and 4 will be described. In the embodiment shown in FIGS. 1 and 2, the control panel 16 is attached to the plunger guide rail 15, but in this embodiment, the control panel 16 is directly installed on the upper end of the plunger 13. . That is, as shown in FIG. 3, a horizontal base 31 is integrally provided at the upper end portion of the plunger 13, and the control panel 16 for controlling the rope-type elevator after the renewal is installed on the base 31.

  In this case, first, the plunger 13 of the hydraulic jack 12 is shortened. At this time, the working oil inside the cylinder of the hydraulic jack 12 is extracted from the pipe. Further, the plunger sheave 14 is removed, and after the removal, a base 31 for installing the control panel 16 is attached, and the control panel 16 is mounted and fixed thereon. Here, in addition to shortening the plunger 13 as shown, the plunger 13 may be extended to install the control panel 16 at a relatively high position. That is, the installation position of the control panel 16 can be set freely.

  When the plunger 13 is fixed at a height other than the lowermost position, as shown in FIG. 4, a plunger fixing ring 32 is attached to the upper end of the cylinder of the hydraulic jack 12, and the plunger 13 is arbitrarily attached. After pulling out to the height, the fixing ring 32 is tightened to fix the cylinder and the plunger 13 together. Further, in the configuration of FIG. 3, the plunger guide rail 15 is left. However, even when the plunger guide rail 15 is completely removed, the control panel 15 according to this configuration can be installed.

  With this configuration, even when the plunger guide rail 15 is completely removed and the device layout is changed due to the arrangement space of the hoistway device, the control panel 16 is directly installed on the plunger 13 to change the guide. The control panel can be installed without being restricted by the rail 15, the degree of freedom of equipment arrangement is increased, and the construction period can be shortened.

  Next, the embodiment shown in FIG. 5 will be described. In this embodiment, the control panel 16 that controls the renewed rope type elevator is disposed on the side of the hydraulic jack 12 including the plunger 13, and the side of the control panel 16 is connected to the hydraulic jack 12 or the bracket 51 by the bracket 51. It is integrally attached to the shaft portion of the plunger 13.

  This configuration is applied to low floor tank formation such as the second floor. That is, when the up / down stroke is about 7 m or less, the installation configuration of the control panel 16 described with reference to FIGS. 1 to 4 may be difficult to install due to the restriction of the height dimension. For example, if the lifting stroke is 6 m and the total height of the control panel 16 is 3 m, there is only a hoistway dimension of about 3 m, and even if an attempt is made to install the control panel 16 above the plunger 13, The problem that the installation space cannot be obtained occurs.

For this reason, as shown in FIG. 5, the plunger guide rail 15 is removed, and the control panel 16 is disposed in the lateral space of the hydraulic jack 12 in the hoistway 11 where the hydraulic jack 12 is left. And the bracket 51 is attached to the side surface, and this bracket 51 is attached to the shaft portion of the main body of the hydraulic jack 12 or the shaft portion of the plunger 13 when the plunger 13 is pulled out as shown. For this reason, the control panel 16 is configured to be installed directly beside the hydraulic jack 12 or its plunger 13.
By configuring in this way, even in a low floor such as the second floor, the installation configuration is not difficult due to the height dimension of the control panel 13, and the installation height of the control panel 16 in the hoistway 11. The control panel 16 can be installed without being affected by the size constraint.

  According to each of these embodiments, when renewing a hydraulic elevator, it becomes possible to install a control panel using a renewal method that diverts existing equipment as much as possible within the restrictions of hoistway shape and equipment layout unique to hydraulic elevators. There is an effect of reducing waste by shortening the construction period and diverting equipment and components.
