Description

Technical Field

[0001] The present invention relates to a storage box, particularly a storage box for storing equipment to be maintained.

Background Art

[0002] Generally, in an elevator, a storage box containing electronic equipment (equipment to be maintained) that controls the operation of a car may be installed on a wall surface inside a hoistway. In such a storage box, inspection work on the electronic equipment stored inside is carried out by opening the cover of the storage box during maintenance inspection or the like.

[0003] By the way, in the hoistway, there are various equipment such as a car that moves up and down, and a safety fence that is temporarily installed when a maintenance worker gets on top of the car to perform maintenance inspection. Therefore, when opening the storage box, it is necessary to provide it so that the cover does not hit the above-mentioned equipment and cannot be opened.

[0004] Patent Document 1 discloses an elevator control device (storage box) provided with a lower slide door and rotating door (cover member) configured to be slidable in the vertical direction and rotatable in the horizontal direction, and provided with a catching protrusion that engages with the rotating door so that the rotating door does not fall off when the lower slide door and rotating door are pulled down.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the storage box described in Patent Document 1, the cover member cannot be removed from the storage box. Therefore, when the cover member needs repair or replacement, it is not possible to remove the cover member from the storage box to perform repairs or replacements. Consequently, when the cover member needs to be replaced, the entire storage box must be replaced, which presents a problem as it makes maintenance and inspection work time-consuming.

[0007] The present invention provides a storage box that can reduce the effort required for maintenance and inspection work. [Means for solving the problem]

[0008] The storage box of the present invention is a storage box for storing equipment to be maintained installed in an elevator shaft, comprising a box body for housing the equipment to be maintained, and a guide unit for attaching a cover member to the box body so as to be movable between a shielding position that covers the equipment to be maintained and an open position that exposes the equipment to the outside, wherein the guide unit is provided with a removal restricting part configured to be movable between a removable position in which the cover member can be removed from the box body and a removal restricting position in which the cover member cannot be removed from the box body.

[0009] In the storage box of the present invention, the removal restriction section is provided with a fixing section for fixing a cover member, and the cover member may be configured to be fixable to the fixing section only when the guide unit is in the removal restriction position.

[0010] In the storage box of the present invention, the storage box may be installed at a position higher than the bottom of the elevator shaft. [Effects of the Invention]

[0011] According to the storage box of the present invention, the cover member can be removed by moving the removal restriction part to a removable position. This makes it possible to remove the cover member from the storage box for replacement or repair, thereby reducing the workload of maintenance and inspection work. [Brief explanation of the drawing]

[Figure 7] This diagram schematically shows the positional relationship between the elevator car and the control panel when the elevator car is raised or lowered to a position close to the control panel. [Modes for carrying out the invention]

[0013] Hereinafter, an elevator 10, which is one embodiment of the present invention, will be described with reference to the drawings. Figure 1 is a schematic diagram showing the configuration of the hoistway 12 of the elevator 10. Figure 2 is a functional block diagram centered on the control panel 40. As shown in Figures 1 and 2, the elevator 10 includes a car 20 and a counterweight 21 suspended so as to be movable vertically within the hoistway 12 via a steel main rope 11, a first fixed pulley 13A, a second fixed pulley 13B, and a hoisting machine M. The first fixed pulley 13A and the second fixed pulley 13B are respectively attached to support parts FL1 and FL2 fixed to a beam 12A located at the top 12T, which is the uppermost part of the hoistway 12.

[0014] Furthermore, in the elevator 10 of this embodiment, the main rope 11 is stretched such that the speed ratio (roping ratio) between the hoisting speed of the sheave M1 provided by the hoisting machine M and the lifting speed of the elevator car 20 is 2:1. Specifically, the main rope 11 is fixed at one end to a support frame FL3 located near the top 12T of the elevator shaft 12 via a hitch BL1, and hangs directly below it, connecting in this order to a pair of lower car pulleys 20a, 20b located at the bottom of the elevator car 20, a first fixed pulley 13A installed at the top 12T of the elevator shaft 12, a sheave M1 of the hoisting machine M fixed directly above the pit 12P in the elevator shaft 12, a second fixed pulley 13B at the top 12T of the elevator shaft 12, and a pulley 21a located on the upper part of the counterweight 21. The other end of the rope is connected and fixed to the beam 12A of the elevator shaft 12 via a hitch BL2. In this embodiment, the lower car pulleys 20a, 20b of the elevator car 20 function as movable pulleys.

[0015] In this embodiment, the hoisting machine M is positioned slightly above the pit 12P of the elevator shaft 12 as part of flood control measures during floods, but it may also be positioned within the pit 12P or at another location within the elevator shaft 12.

[0016] The elevator 10 includes a control panel (storage box) 40 that comprehensively controls the operation of the car 20. The control panel 40 is installed on the top 12T of the hoistway 12, that is, on the wall surface of the hoistway 12 located slightly above the uppermost floor landing 14A. In this embodiment, the control panel 40 is installed slightly above the uppermost floor landing 14A, but the present invention is not limited thereto. For example, the control panel 40 may be installed at a position higher than the pit 12P of the hoistway 12, specifically, slightly above the landings 14 on the intermediate floors or the lowest floor.

[0017] As shown in FIG. 1, the car 20 has a car door 22. On the other hand, landing doors 16A, 16B, 16C,... (hereinafter, appropriately referred to as landing door "16" when there is no need to distinguish specifically) are provided at each floor landing 14A, 14B, 14C,... (hereinafter, appropriately referred to as landing "14" when there is no need to distinguish specifically).

[0018] Each landing door 16 is constantly biased in the direction in which the door closes via an elastic member such as a spring, and is held in a closed state via lock mechanisms 17A, 17B, 17C,... (hereinafter, appropriately referred to as lock mechanism "17" when there is no need to distinguish specifically) attached to the upper part. And each landing door 16 is only provided such that the fixing by the lock mechanism 17 is released and it can be opened when the above-described car 20 stops at a preset landing position, that is, a position where the vertical position of the floor surface in the car interior space of the car 20 substantially coincides with the vertical position of the floor surface at the landing 14 where passengers can board and alight from the car 20 via the landing door 16 (in other words, a position where the landing door 16 and the car door 22 face each other).

[0019] In addition, the lock mechanism 17 is provided with door open sensors 18A, 18B, 18C,... (hereinafter, appropriately referred to as door open sensor "18" when there is no need to distinguish specifically) having a function of detecting the open / closed state of the landing door 16.

[0020] As shown in Fig. 1, on the upper part of the car 20T, which is the rooftop part of the car 20, an upper-car operation unit 26 is provided. The upper-car operation unit 26 includes a switching operation unit 27 (see Fig. 2) for performing an operation to switch the driving mode of the car 20 from the normal driving mode described later to manual driving, and a lifting operation unit 28 (see Fig. 2) for performing the lifting and lowering operation of the car 20 during manual driving. Thus, during maintenance and inspection, the car 20 can be lifted and lowered with a maintenance worker on board on the car 20T.

[0021] On the car 20, as shown by the dashed line in Fig. 1, a safety fence 70 is installed on the outer peripheral part of the upper-car 20T that serves as a scaffold for the maintenance worker during maintenance and inspection. This safety fence 70 is, for example, an assembled fence and is installed only along the outer peripheral part of the upper-car 20T during maintenance and inspection. And the safety fence 70 is removed from the outer peripheral part of the upper-car 20T at the end of maintenance and inspection and stored in a predetermined location of the upper-car 20T.

[0022] As shown in Fig. 2, the control panel 40 includes a storage device 43 composed of a ROM, a RAM, an HDD, etc. in which various control programs are stored, and an arithmetic processing device (not shown) such as a CPU. The operation control unit 44 controls the driving of the hoist M by reading the above control program from the storage device 43 and performing arithmetic processing, and functions as a door monitoring unit 46 that detects the open / closed state of the landing door 16 via the above-described door open sensor 18.

[0023] The operation control unit 44 is configured to execute a normal driving mode in which the car 20 is lifted and lowered (moved) to each floor landing 14 based on a landing call to call the car 20 to the landing 14 performed via the landing operation panels 15A, 15B, 15C,... (hereinafter, appropriately referred to as the landing operation panel "15" when there is no need for particular distinction) installed at each floor landing 14, and a destination floor operation, in other words, a car call operation, performed via the car operation panel 24 installed inside the car 20.

[0024] The car control panel 24 (see Figure 2), like the car control unit 26 described above, also has the function of switching the operating mode of the elevator car 20 from the normal operating mode (described later) to manual operation, and of raising and lowering the elevator car 20 when it is in manual operation mode.

[0025] Furthermore, the operation control unit 44 also has a prohibition mode that prohibits the execution of the normal operation mode described above. This prohibition mode is executed when the elevator car 20 is not stopped (landed) at a preset landing position, in other words, at a position facing the landing door 16, when the opening of the landing door 16 is detected via the door monitoring unit 46.

[0026] Here, the elevator car 20 is fitted with a floor position detection unit 45 that has the function of detecting the position of the elevator car 20. This landing position detection unit 45 has the function of detecting light-shielding plates (not shown) provided on the wall surface of the hoistway 12 corresponding to each landing 14. As a result, the operation control unit 44 can determine whether or not the elevator car 20 is located at a preset landing position.

[0027] Next, the configuration of the control panel 40 will be explained with further reference to Figures 3(a) and 3(b). Figure 3(a) is a diagram showing the front configuration of the control panel 40, and Figure 3(b) is a diagram showing the rear configuration of the slide cover 52 included in Figure 3(a).

[0028] As shown in Figures 3(a) and 3(b), the control panel 40 has a roughly vertically elongated box-shaped exterior, a sliding cover 52 that covers a front opening 50a (see Figure 5(a)) located directly below the upper panel 51d that covers the upper front of the housing 50, and a guide unit 54 that slides the sliding cover 52 vertically. The housing 50 houses maintenance equipment 53 (see Figure 5(a)) consisting of various electronic devices for controlling the raising and lowering of the elevator car 20.

[0029] As shown in Figure 3(b), the slide cover 52 is a metal panel that is roughly rectangular in shape when viewed from the front, and is fixed to the housing 50 with its upper end 52u inserted inside the upper panel 51d. The slide cover 52 has identical keyhole holes H1 to H4 (hereinafter referred to as "keyhole H" unless otherwise specified) at both the upper and lower left and right ends, and identical slits SL1 and SL2 (hereinafter referred to as "slit SL" unless otherwise specified) at both the left and right ends of the lower end.

[0030] The keyhole holes H1 to H4 of the slide cover 52 are through holes for fixing the slide cover 52 to the side portions 51a and 51b of the housing 50 using bolts BT1 to BT4. Slits SL1 and SL2 are provided at both ends of the lower end of the slide cover 52. These slits SL1 and SL2 are holes for fixing the lower end of the slide cover 52 to the bottom portion 51c of the housing 50 via bolts BT5 and BT6. The slide cover 52 is fixed to the housing 50 by bolts BT1 to BT6 (hereinafter referred to as "bolt BT" as appropriate unless otherwise specified) which are inserted into the keyhole holes H1 to H4 and slits SL1 and SL2, respectively.

[0031] Furthermore, sliding parts 52a and 52b are provided at both the left and right ends of the upper side of the slide cover 52, which movably engage with the guide unit 54 described above. Here, since both sliding parts 52a and 52b have the same configuration except that they are provided symmetrically, in the following description, the sliding part 52b will be mainly described, and the description of the sliding part 52a will be omitted as appropriate. As shown in Figure 3(c), the sliding part 52b is constructed by bending it into a roughly U-shape.

[0032] Here, the configuration of the guide unit 54 will be explained using Figures 4(a) to 4(c). Figure 4(a) shows the side configuration of the housing 50 when the slide cover 52 is closed, that is, when the slide cover 52 is in a shielding position that blocks the front opening 50a of the housing 50 (see Figure 5(a)). Figure 4(b) shows the side configuration of the housing 50 when the sliding parts 52a and 52b of the slide cover 52 are lowered to a position where they contact the bottom 51c of the housing 50, that is, in the open position. Figure 4(c) shows the position of the movable bracket 62 when the slide cover 52 is removed from the housing 50, similar to Figure 4(b).

[0033] As shown in Figures 4(a) to 4(c), the guide unit 54 includes a left guide section 56a (see Figures 5(a) and 5(b)) provided at the left end of the housing 50 and a right guide section 56b provided at the right end of the housing 50. The right guide section 56b and the left guide section 56a have almost identical configurations except that they are provided at both the left and right ends of the housing 50 in a symmetrical manner. Therefore, in the following description, only the configuration of the right guide section 56b will be described, and the description of the left guide section 56a will be omitted as appropriate.

[0034] The right-side guide section 56b includes a guide bracket 61 and a movable bracket (removal restricting section) 62 attached to the right end of the housing 50, and has the function of guiding the sliding section 52b provided at the right end of the slide cover 52 vertically between the open position and the shielded position as described above. As shown in Figure 4(a), the guide bracket 61 has a substantially U-shaped cross-section and functions as a guide rail together with the movable bracket 62, which will be described later, and is a long metal member that extends along the vertical direction of the housing 50.

[0035] Figure 4(d) shows the cross-sectional configuration when cut along the BB line shown in Figure 4(a). In Figure 4(d), cross-sectional hatching has been omitted to avoid a cluttered illustration. As shown in Figure 4(d), the sliding portion 52b of the slide cover 52 is engaged with the guide bracket 61 so as to be movable in the vertical direction.

[0036] Furthermore, the movable bracket 62, positioned directly below the guide bracket 61, has a roughly U-shaped cross-section similar to the guide bracket 61 and serves to guide the sliding portion 52b in the vertical direction. As shown in Figure 4(b), the movable bracket 62 is attached to the side portion 51b of the housing 50 so as to be slidable in the vertical direction by loosening the bolts BT7 and BT8 (hereinafter referred to as "bolt BT" as appropriate unless otherwise specified) that are exposed to the outside when the slide cover 52 is lowered to the lowest end of its range of motion, i.e., to the open position where the sliding portion 52b of the slide cover 52 contacts the bottom portion 51c of the housing 50.

[0037] Here, Figure 5(a) shows the configuration of the housing 50 when the movable bracket 62 is in the removal restriction position P1, and Figure 5(b) shows the configuration of the housing 50 when the movable bracket 62 is in the removable position P2.

[0038] As shown in Figures 5(a) and 5(b), the movable bracket 62 is fixed to the side portion 51b of the housing 50 via fixing bolts BT7 and BT8 inserted through an elongated hole 62a provided in the center. This elongated hole 62a serves to fix the movable bracket 62 to the side portion 51b of the housing 50 so that it can move between a removal restriction position P1, in which the upper end of the movable bracket 62 abuts against the lower end of the guide bracket 61 when the fixing bolts BT7 and BT8 are loosened, and a removable position P2, which is below the removal restriction position P1.

[0039] When the movable bracket 62 is in the removal restriction position P1, a gap D1 is formed between the movable bracket 62 and the guide bracket 61. Conversely, when the movable bracket 62 is in the removable position P2, the gap between the movable bracket 62 and the guide bracket 61 expands to a gap D2. Here, the relationship between the sizes of the gaps D1 and D2 and the vertical dimension L of the sliding part 52b (see Figure 4(b)) is set to satisfy the following equation (1).

[0040] D1 <L<D2···(1) As a result, when the movable bracket 62 is in the removable position P2, the sliding portion 52b of the slide cover 52 can be removed from the movable bracket 62 (see Figure 4(c)). On the other hand, when the sliding portion 52b is in the removal restriction position P1, it cannot be removed from the right-side guide portion 56b (see Figure 4(b)). This prevents the slide cover 52 from falling off the housing 50.

[0041] Furthermore, a screw hole (fixing part) 62b for fixing the slide cover 52 is provided at the lower end of the movable bracket 62. This screw hole 62b is for fixing the slide cover 52 with a bolt BT and is positioned to overlap with a keyhole H4 (see Figure 3(a)) provided at the lower end of the slide cover 52 when the slide cover 52 is in the shielded position.

[0042] As shown in Figure 3(b), the eyelet hole H4 consists of an elongated slot H4-1 located at the top and a rounded slot H4-2 located below the slot H4-1 and wider than the slot H4-1. The slot H4-1 of the eyelet hole H4 is configured to allow the slide cover 52 to be fixed to the side portion 51b of the housing 50 by screwing the bolt BT described above into it. On the other hand, the rounded slot H4-2 of the eyelet hole H4 is wider than the diameter of the bolt BT, so it is not possible to fix the slide cover 52 to the side portion 51b of the housing 50 through it.

[0043] Here, Figure 6(a) shows the degree of overlap between the keyhole H4 and the screw hole 62b in the movable bracket 62 when the slide cover 52 is moved to the shielded position while the movable bracket 62 is fixed in the removal restriction position P1. Figure 6(b) shows the degree of overlap between the keyhole H4 and the screw hole 62b in the movable bracket 62 when the slide cover 52 is moved to the shielded position while the movable bracket 62 is located in the removable position P2, which is lower than the removal restriction position P1.

[0044] As shown in Figures 6(a) and 6(b), when the movable bracket 62 is in the removal restriction position P1, the elongated hole H4-1 of the keyhole hole H4 of the slide cover 52 and the screw hole 62b of the movable bracket 62 overlap, so the slide cover 52 can be fixed via the bolt BT. On the other hand, when the movable bracket 62 is in the removable position P2, the round hole H4-2 of the keyhole hole H4 and the screw hole 62b of the movable bracket 62 overlap, so the slide cover 52 cannot be fixed via the bolt BT.

[0045] Therefore, when removing and replacing the slide cover 52, the movable bracket 62 must be returned from the removable position P2 to the removal restriction position P1 and fixed in place before the slide cover 52 can be installed. As a result, in order to complete the work of fixing the slide cover 52 to the housing 50 via the movable bracket 62, it becomes necessary to fix the movable bracket 62 to the removal restriction position P1 in advance. This prevents forgetting to return the movable bracket 62 to the removal restriction position P1.

[0046] Next, we will explain the procedure for performing maintenance and inspection work on the control panel 40 with two maintenance personnel, referring further to Figure 7. Figure 7 schematically shows how maintenance and inspection work on the control panel 40 is performed while one maintenance worker is inside the elevator car 20, specifically on the upper level 20T. As shown in Figure 7, the other maintenance worker, who is already inside the elevator car 20, switches the operating mode from normal operation mode to manual operation mode via the car operation panel 24 so that one maintenance worker can board the upper level 20T from the top floor landing 14A (see Figure 1). At the same time, the elevator car 20 is raised or lowered to a position where the other maintenance worker, who is waiting at the top floor landing 14A (see Figure 1), can board the upper level 20T.

[0047] Next, one of the maintenance personnel waiting at the top floor landing 14A uses a special tool to open the landing door 16A (see Figure 1) and boards the elevator car 20T, switching to manual operation via the switching operation unit 27 (see Figure 2) in the elevator car operation unit 26. Then, as shown by the dashed line in Figure 1, the safety fence 70, which is pre-loaded on the elevator car 20T, is assembled and installed.

[0048] Here, Figure 7 schematically shows how maintenance personnel perform maintenance and inspection work on the control panel 40 while riding on the upper part 20T of the elevator car 20. As shown in Figure 7, the elevator car 20 is manually raised and lowered via the lifting and lowering operation unit 28 (see Figure 2) of the upper operation unit 26 (see Figure 2) to a position close to the control panel 40.

[0049] Next, the bolts BT (see Figure 3(a)) that secure the slide cover 52 of the control panel 40 to the housing 50 are removed, and the slide cover 52, which covers the opening 50a on the lower front side of the control panel 40, is slid from the shielded position shown by the solid line in Figure 7 to the open position shown by the dashed line. At this time, since the slide cover 52 slides in the vertical direction, it can be opened and closed without hitting the safety fence 70 installed on the top 20T of the cage. Furthermore, since the movable bracket 62 that guides the sliding parts 52a, 52b of the slide cover 52 (see Figure 4(b)) in the vertical direction is located in the removal restriction position P1, the slide cover 52 will not fall off.

[0050] Furthermore, when removing the slide cover 52 from the control panel 40, as shown in Figure 4(b), loosen the bolts BT that fix the movable bracket 62 (see Figure 5(a)) of the right guide section 56b to the side section 51b of the housing 50, and slide it downward from the removal restriction position P1 to the removable position P2. Similarly, loosen the bolts that fix the movable bracket 64 (see Figure 5(a)) of the left guide section 56a, and slide it downward. The movable bracket 64 corresponds to the removal restriction section.

[0051] Then, as shown in Figure 4(c), the slide cover 52 is slightly lifted and the sliding portion 52b of the slide cover 52 is moved from the position indicated by the dashed line to the position indicated by the solid line through the gap D2 between the guide bracket 61 and the movable bracket 62 (see Figure 5(b)) to remove it from the movable bracket 62. Similarly, the sliding portion 52a of the left guide portion 56a is also removed through the gap between the guide bracket 63 (see Figure 5(b)) and the movable bracket 64. This completes the removal of the slide cover 52.

[0052] As described above, even when the movable brackets 62 and 64 are moved to the removable position P2, the slide cover 52 cannot be removed unless the slide cover 52 is slightly lifted and the sliding parts 52a and 52b are removed from the gap D2 between the movable brackets 62 and 64 and the guide brackets 61 and 63. This prevents the slide cover 52 from being accidentally dropped during the removal process.

[0053] Next, when installing the slide cover 52, as shown in Figure 4(c), insert the sliding portion 52b of the slide cover 52 between the guide bracket 61 and the movable bracket 62 and set it in a position where it contacts the bottom 51c of the housing 50, as shown by the dashed line in Figure 4(c). Similarly, insert the sliding portion 52a of the slide cover 52 between the guide bracket 63 and the movable bracket 64 and set it in a position where it contacts the bottom 51c of the housing 50. In this state, move the movable bracket 62 of the right guide portion 56b upward from the removable position P2 to the removal restriction position P1 and tighten the bolt BT to fix it in place. Similarly, move the movable bracket 64 of the left guide portion 56a to the removal restriction position and fix it in place.

[0054] Next, the slide cover 52 shown in Figure 4(a) is slid upward, and the upper end portion 52u of the cover 52 is inserted into the inside of the upper panel 51d, moving it to the shielded position. Then, the slide cover 52 is secured using the bolts BT as shown in Figure 3(a). This completes the removal and installation of the slide cover 52.

[0055] According to the control panel 40 of this embodiment, the slide cover 52 can be removed by positioning the movable bracket 62 in the removable position P2. This allows the slide cover 52 to be removed from the housing 50 for replacement or repair. As a result, the amount of work required for maintenance and inspection can be reduced.

[0056] The present invention can be implemented in various forms with improvements, modifications, or alterations based on the knowledge of those skilled in the art, without departing from its spirit. Furthermore, the invention may be implemented in a form in which any of its defining features is replaced with other technologies, as long as the same function or effect is achieved.
