AI Technical Summary

Technical Problem

Elevator car frames deform due to concentrated tensile loads from counterweights when fixed to guide rails, necessitating larger vertical cross-sectional dimensions, which in turn increases the height and overhead dimensions of the elevator shaft, contradicting building owner demands for a smaller overhead dimension.

Method used

The elevator design includes a stopper mechanism where the second engaging member is supported by both the upper and vertical frames, distributing the tensile load across both structures, thereby maintaining the vertical cross-sectional dimension of the upper frame without increasing it.

Benefits of technology

This distribution of load prevents upper frame deformation, allowing for reduced height and overhead dimensions in the elevator car and shaft, meeting building owner requirements while ensuring structural integrity.

Description

Technical Field

[0001] The present invention relates to an elevator.

Background Art

[0002] In recent years, in a machine-roomless elevator, there has been an increasing demand to install a hoisting machine above the hoistway so that the hoisting machine is not flooded due to abnormal weather such as heavy rain. On the other hand, when performing maintenance and inspection work on the hoisting machine installed above the hoistway, an operator gets into the car from the landing on the top floor of the building and uses the ceiling of the car as a work floor. In that case, there is known a technique of fixing the car to the guide rail by a stopper mechanism so that the car is not pulled up by the counterweight even when the brake that regulates the movement of the main rope is released (for example, see Patent Document 1).

[0003] The stopper mechanism includes an engaged member fixed to the guide rail and an engaging member provided on the car. When performing maintenance and inspection work on the hoisting machine, the operator can fix the car to the guide rail by engaging the engaging member with the engaged member.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When the elevator car is fixed to the guide rail by the stopper mechanism and the brake is released, a tensile load from the counterweight is applied to the elevator car. In the technology described in Patent Document 1, the engaging member of the stopper mechanism is supported only by the upper frame of the elevator car. As a result, the tensile load from the counterweight is concentrated on the upper frame of the elevator car, which may cause deformation of the upper frame. Therefore, in elevator cars equipped with a stopper mechanism, it was necessary to ensure a large vertical cross-sectional dimension of the upper frame so that it could withstand the tension load from the counterweight.

[0006] However, if the vertical cross-sectional dimension of the upper frame is made larger, the height dimension of the elevator car frame will also increase accordingly. Furthermore, if the height dimension of the elevator car frame increases, the overhead dimension of the elevator shaft needs to be made larger accordingly. The overhead dimension is the distance from the landing floor level of the top floor to the ceiling of the elevator shaft. The building owner (the client who commissioned the construction) has a request to make the overhead dimension smaller, and in order to meet this request, the height dimension of the elevator car frame must be kept small.

[0007] The object of the present invention is to provide an elevator that can withstand the tensile load from a counterweight without increasing the vertical cross-sectional dimensions of the upper frame of the elevator car when the elevator car is fixed to the guide rail by a stopper mechanism. [Means for solving the problem]

[0008] To address the above issues, for example, the configuration described in the claims may be adopted. The present invention includes several means for solving the above problems, but one example is an elevator having a car with an upper frame and vertical frames, a guide rail for guiding the movement of the car, a first engaging member provided on the guide rail, and a second engaging member provided on the car, and a stopper mechanism for fixing the car to the guide rail by engaging the first engaging member and the second engaging member, wherein the second engaging member is supported on both the upper frame and the vertical frames. [Effects of the Invention]

[0009] According to the present invention, when the elevator car is fixed to the guide rail by a stopper mechanism, it is possible to withstand the tensile load from the counterweight without increasing the vertical cross-sectional dimension of the upper frame of the elevator car. Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] Embodiments of the present invention will now be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same function or configuration are denoted by the same reference numerals, and redundant descriptions are omitted.

[0012] <Elevator Configuration> Figure 1 is a schematic diagram showing the configuration of an elevator according to this embodiment. As shown in FIG. 1, the elevator 10 is a so-called machine-roomless elevator that does not require a machine room to be provided on the rooftop of a building or the like. The elevator 10 includes a car 11, a hoist 12, a main rope 13, a counterweight 14, and a compensating chain 15.

[0013] The car 11 is guided by a guide rail (not shown) and moves up and down in the hoistway 16 in the vertical direction (hereinafter, also referred to as "ascending and descending"). When a car call button (not shown) provided at the landing 17 on each floor is pressed, or when a destination floor button provided in the car compartment of the car 11 is pressed, the car 11 moves to the landing 17 on the floor designated by the button operation and stops.

[0014] The hoist 12 is a device that winds up the main rope 13 to raise and lower the car 11. The hoist 12 includes a sheave 12a and a drive source (not shown) that rotates the sheave 12a. The hoist 12 is installed at the upper part of the hoistway 16. More specifically described, the hoist 12 is installed near the top of the hoistway 16.

[0015] The main rope 13 is wound around a weight pulley 18 disposed at the upper end of the counterweight 14, the sheave 12a of the hoist 12 described above, and two car lower pulleys 19 disposed at the lower part of the car 11. Also, both ends of the main rope 13 are supported by a rope support mechanism (not shown).

[0016] The counterweight 14 is a weight that balances the weight with the car 11 in order to reduce the load when the hoist 12 winds up the main rope 13. The counterweight 14 moves in the hoistway 16 in the opposite direction to the car 11. A buffer 20 is disposed below the counterweight 14. The buffer 20 is a device that mitigates the impact caused by contact with the counterweight 14 when the counterweight 14 descends beyond the lower limit position. Although omitted in FIG. 1, a buffer for shock mitigation is also disposed below the car 11.

[0017] The compensating chain 15 is a chain for compensating for the imbalance of the weight of the main rope 13 due to the position of the car 11. One end of the compensating chain 15 is connected to the counterweight 14, and the other end of the compensating chain 15 is connected to the car 11.

[0018] <Configuration of the car> FIG. 2 is a perspective view showing the configuration of a car included in an elevator according to an embodiment. In the present embodiment, the front-back, up-down, and left-right directions are defined based on the case where the car 11 in the hoistway 16 is viewed from the landing 17 side of the elevator 10. In this case, the front side as viewed from the landing 17 side is the front direction, the back side is the rear direction, the upper side is the upward direction, the lower side is the downward direction, the left side is the left direction, and the right side is the right direction.

[0019] As shown in FIG. 2, the car 11 includes a car frame 25 and a car compartment 26 disposed inside the car frame 25. An apron 22 is attached to the front portion of the car 11. The apron 22 is a member that ensures the safety of users by shielding the gap generated at the elevator entrance due to the landing error of the car 11. The car 11 is movably supported on a guide rail (not shown) by an upper guide 23 and a lower guide 24 attached to the car frame 25.

[0020] The car compartment 26 forms an accommodation space for carrying passengers, luggage, etc. The car compartment 26 is composed of a car floor 27, side plates 28, and a ceiling 29. A car door (not shown) is provided on the front surface of the car compartment 26 so as to be openable and closable. The car floor 27 and the ceiling 29 are arranged to face each other in the vertical direction through the accommodation space. The side plates 28 are arranged to surround the four sides of the accommodation space except for the part of the car door (not shown). <000010The car frame 25 is formed as a vertically elongated rectangle when viewed from the front or back. The car frame 25 is arranged to surround the car compartment 26. The car frame 25 has an upper frame 31 positioned above the car compartment 26, a lower frame (not shown) positioned below the car compartment 26, and a pair of vertical frames 33 positioned on the left and right sides of the car compartment 26. The upper frame 31 is a member that extends long in the left-right direction. The upper frame 31 is horizontally spanned between the upper ends of the pair of vertical frames 33. One end and the other end of the upper frame 31 in the longitudinal direction are connected to the upper ends of the corresponding vertical frames 33. The pair of vertical frames 33 are arranged to face each other in the left-right direction. Each vertical frame 33 is a member that extends long in the up-down direction. The upper end of the vertical frame 33 is connected to the longitudinal end of the upper frame 31, and the lower end of the vertical frame 33 is connected to the longitudinal end of the lower frame.

[0022] In the elevator 10 configured as described above, when performing maintenance and inspection work on the hoisting machine 12 installed at the top of the hoistway 16, the worker 21 (see Figure 1) boards the elevator car 11 from the landing 17 on the top floor of the building and uses the ceiling 29 of the elevator car 11 as a work platform. At that time, the elevator 10 is equipped with a stopper mechanism 40 (Figure 3) to prevent the elevator car 11 from rising due to being pulled by the counterweight 14. One stopper mechanism 40 is provided on the left side and one on the right side of the elevator car 11. The stopper mechanisms 40 are arranged symmetrically. The worker 21 performing maintenance and inspection work on the hoisting machine 12 fixes the elevator car 11 to the guide rail 30 (see Figure 3) by operating the stopper mechanism 40 before releasing the brake (not shown) of the hoisting machine 12 that restricts the movement of the main rope 13. The guide rail 30 is fixed to the wall 34 of the hoistway in a state where it is centered to stand vertically. The guide rails 30 are arranged in pairs on the left and right sides of the elevator car 11 and, by engaging with the upper guide 23 and lower guide 24 provided on the elevator car 11, support the elevator car 11 so that it can move freely in the vertical direction.

[0023] <Configuration of the stopper mechanism> Figure 3 shows the configuration of the stopper mechanism provided in the elevator according to this embodiment. As shown in Figure 3, the stopper mechanism 40 includes a stopper pin operating section 41 and a stopper pin receiving section 42. The stopper pin operating section 41 includes a stopper pin 43, a support member 44 that supports the stopper pin 43, a first fixing bracket 45, a second fixing bracket 46, a locking member 47, and a cover member 48 (see Figure 4). The stopper pin 43 is provided in the elevator car 11 as an example of a second engaging member. The support member 44 is a member that supports the stopper pin 43 so that it can engage with and disengage from the engaging member 51. The first fixing bracket 45 and the second fixing bracket 46 are elements that constitute a fixing member. The fixing member is connected to the support member 44 and is fixed to both the upper frame 31 and the vertical frame 33. The configuration of the stopper pin operating section 41 will be described in detail later.

[0024] The stopper pin receiving portion 42 is equipped with an engaging member 51. The engaging member 51 is provided on the guide rail 30 as an example of a first engaging member. The engaging member 51 is fixed to the guide rail 30. The engaging member 51 is provided with a through hole 52. The through hole 52 is a hole into which the stopper pin 43 is inserted when the elevator car 11 is fixed to the guide rail 30 by the stopper mechanism 40. In this embodiment, as an example, the stopper pin 43 is a pin with a circular cross-section (round pin), and the through hole 52 is a circular hole corresponding to the cross-sectional shape of the stopper pin 43. The engaging member 51 is fixed to the guide rail 30 by a bolt and nut mechanism 53. The bolt and nut mechanism is a mechanism that fastens and fixes members together using bolts and nuts.

[0025] The configuration of the stopper pin operating section 41 will be described in detail below with reference to Figures 3 to 9. Figure 4 is a perspective view showing the arrangement of the stopper pin operating section, and Figure 5 is a perspective view showing the support structure of the stopper pin. Figure 6 is a plan view showing the support structure of the stopper pin, Figure 7 is a front view showing the support structure of the stopper pin, Figure 8 is a left side view showing the support structure of the stopper pin, and Figure 9 is a right side view showing the support structure of the stopper pin. Note that in Figure 4, the vertical frame is omitted, and some of the bolt and nut mechanisms that fix the members together are also omitted.

[0026] The stopper pin 43 is supported on both the upper frame 31 and the vertical frame 33 by a support member 44, a first fixing bracket 45, and a second fixing bracket 46. As shown in Figure 3, one end of the stopper pin 43 is inserted into the through hole 52 of the engaging member 51 when performing maintenance and inspection work on the hoisting machine 12. This engages the stopper pin 43 with the engaging member 51. A locking bar 54 is attached near the other end of the stopper pin 43. The locking bar 54 is positioned to protrude radially outward from the outer circumferential surface of the stopper pin 43.

[0027] The support member 44 supports the stopper pin 43 so that it can move in the left-right direction. The support member 44 also supports the stopper pin 43 so that it can rotate around its central axis. The support member 44 is an integral structure having a pair of support pieces 441 and 442 that face each other in the left-right direction, and a connecting piece 443 that connects the pair of support pieces 441 and 442. As shown in Figure 5, the pair of support pieces 441 and 442 are provided with guide holes 441a and 442a, respectively. The stopper pin 43 is supported so that it can move and rotate as described above by being inserted into the guide holes 441a and 442a of the support member 44. The pair of support pieces 441 and 442 are also provided with fixing holes 441b and 442b, respectively. The fixing holes 441b and 442b are holes for fixing the support member 44 to the first fixing bracket 45.

[0028] As shown in Figures 3 and 4, the first fixing bracket 45 is an integral structure having three connecting pieces 451, 452, and 453. Connecting piece 451 corresponds to the first connecting piece, and connecting piece 452 corresponds to the second connecting piece. Connecting pieces 451 and 453 are arranged facing each other in the left-right direction. Connecting piece 452 is arranged perpendicular to connecting pieces 451 and 453. The first fixing bracket 45 is bent into a roughly inverted L-shape (roughly inverted J-shape) when viewed from the front-rear direction. As shown in Figure 4, the width dimension W1 of the first fixing bracket 45 in the front-rear direction is greater than the width dimension W2 of the upper frame 31. The first fixing bracket 45 is positioned to support the upper frame 31 across its entire width. In addition, one end of the first fixing bracket 45 in the width direction is positioned to protrude forward from the upper frame 31.

[0029] The first fixing bracket 45 is connected to the upper frame 31, the vertical frame 33, and the support member 44 by three connecting pieces 451, 452, and 453. Specifically, the connecting piece 451 is connected and fixed to the support piece 441 of the support member 44 by a bolt and nut mechanism 55 in the left-right direction, which corresponds to the first direction. The bolt and nut mechanism 55 is positioned offset forward of the upper frame 31. The bolt and nut mechanism 55 is attached using a fixing hole 441b (see Figure 5) provided in the support piece 441. The connecting piece 451 is also connected and fixed to the main surface 33a (see Figure 3) of the vertical frame 33 by a bolt and nut mechanism 56 in the left-right direction. The main surface 33a of the vertical frame 33 corresponds to the first surface of the vertical frame 33. The bolt and nut mechanism 56 is positioned within the width dimension W2 of the upper frame 31. On the other hand, the connecting piece 452 is connected and fixed to the main surface (bottom surface) 31a of the upper frame 31 by a bolt and nut mechanism 57 in the vertical direction, which corresponds to the second direction. The main surface 31a of the upper frame 31 corresponds to the first surface of the upper frame 31. The bolt and nut mechanism 57 is positioned within the width dimension W2 of the upper frame 31. The connecting piece 453 is connected and fixed to the support piece 442 of the support member 44 by a bolt and nut mechanism 58 in the left-right direction. The bolt and nut mechanism 58 is attached using a fixing hole 442b (see Figure 5) provided in the support piece 442. The bolt and nut mechanism 58 is positioned coaxially with the bolt and nut mechanism 55 described above.

[0030] As shown in Figures 3 and 4, the second fixing bracket 46 is an integral structure having two connecting pieces 461 and 462. The second fixing bracket 46 is formed in a flat plate shape. Connecting piece 461 corresponds to the third connecting piece, and connecting piece 462 corresponds to the fourth connecting piece. The second fixing bracket 46 is connected to the upper frame 31, the vertical frame 33, and the support member 44 by the two connecting pieces 461 and 462. Specifically, connecting piece 461 is connected and fixed to the connecting piece 443 of the support member 44 by a bolt and nut mechanism (not shown) in the front-rear direction, which corresponds to the third direction. This bolt and nut mechanism is attached using fixing holes 59 provided in the connecting piece 461 and the connecting piece 443. In addition, connecting piece 461 is connected and fixed to the side surface 31b of the upper frame 31 by a bolt and nut mechanism 60 (see Figure 3) in the front-rear direction. The side surface 31b of the upper frame 31 corresponds to the second surface of the upper frame 31. The connecting piece 462 is connected and fixed to the side surface 33b of the vertical frame 33 in the front-rear direction by a bolt and nut mechanism 61. The side surface 33b of the vertical frame 33 corresponds to the second surface of the vertical frame 33.

[0031] The locking member 47 is connected and fixed to the support piece 442 of the support member 44 by a bolt and nut mechanism 65 in the left-right direction. The locking member 47 is provided with two locking grooves 47a and 47b. The two locking grooves 47a and 47b are formed at a predetermined distance apart in the left-right direction. Each of the locking grooves 47a and 47b is formed in a substantially U-shape when viewed from the front-rear direction. The locking bar 54 attached to the stopper pin 43 is locked into either the locking groove 47a or the locking groove 47b.

[0032] The locking groove 47a is a groove for holding the stopper pin 43 in the engaged position, and the locking groove 47b is a groove for holding the stopper pin 43 in the retracted position. The engaged position is the position in which the stopper pin 43 engages with the engaging member 51, as shown in Figure 3, and the retracted position is the position in which the stopper pin 43 has retracted (moved back) from the engaged position. When the locking bar 54 is locked in the locking groove 47a, the stopper pin 43 is inserted into the through hole 52 of the engaging member 51, and when the locking bar 54 is locked in the locking groove 47b, the stopper pin 43 is disengaged from the through hole 52 of the engaging member 51. The operator can lock the locking bar 54 in the locking groove 47a or locking groove 47b by pinching the locking bar 54 with their fingers and rotating and moving the stopper pin 43.

[0033] The cover member 48 is a component that protects switches, wiring, etc. (not shown). The locking member 47 is, for example, detachably attached to the locking member 47. When the cover member 48 is attached, the locking bar 54 interferes with (contacts) the cover member 48, restricting the rotation range of the stopper pin 43. Therefore, if an operator needs to operate the stopper pin 43 by pinching the locking bar 54 with their fingers, the cover member 48 must be removed.

[0034] In addition to the configuration described above, the elevator 10 according to this embodiment is equipped with a connecting bracket 70 (see Figure 4) that connects the upper frame 31 and the vertical frame 33. Similar to the stopper mechanism 40 described above, the connecting bracket 70 is arranged symmetrically on the left and right sides of the elevator car 11, one on each side. The connecting bracket 70 is an integral structure having two connecting pieces 701 and 702. The connecting bracket 70 is connected to the upper frame 31 and the vertical frame 33 by the two connecting pieces 701 and 702. Specifically, the connecting piece 701 is connected and fixed to the side surface 31b of the upper frame 31 in the front-rear direction by a bolt and nut mechanism 71. The connecting piece 702 is connected and fixed to the side surface 33b of the vertical frame 33 in the front-rear direction by a bolt and nut mechanism 72.

[0035] The connecting bracket 70 is positioned so as to face the second fixing bracket 46 with the upper frame 31 in between in the front-rear direction. The connecting bracket 70 has the same structure as the second fixing bracket 46 described above. The connecting bracket 70 is provided with an elongated hole 70a, and the second fixing bracket 46 is also provided with an elongated hole 46a. The elongated holes 46a and 70a correspond to position adjustment parts that shift the position of the upper frame 31 relative to the vertical frame 33 upward from the reference position. The reference position is the position where the upper frame 31 is finally attached during the assembly process of the elevator car 11.

[0036] At the connection point between the upper frame 31 and the vertical frame 33, the upper frame 31 can be moved in the longitudinal direction (vertical direction) of the elongated holes 46a and 70a by loosening the tightening of the upper bolt and nut mechanisms 61 and 72 and removing the lower bolt and nut mechanisms 61 and 72. In the assembly process of the elevator car 11, the ceiling 29 and side panels 28 are attached after the car frame 25 is assembled. At that time, the ceiling 29 is fastened inside the car frame 25 and near the upper frame 31, and the side panels 28 are attached in that state. However, if the upper frame 31 is left in the reference position, the ceiling 29 will interfere with the side panels 28, making it difficult to attach the side panels 28. In such cases, as described above, the position of the upper frame 31 can be shifted upward along the elongated holes 46a and 70a, and the upper frame 31 can be temporarily fixed there by tightening the bolt and nut mechanisms 61 and 72. This allows the side plates 28 to be attached while avoiding interference with the ceiling 29, and then the ceiling 29 can be attached to the side plates 28. Alternatively, after the side plates 28 and ceiling 29 have been attached to the inside of the cage frame 25, the upper frame 31 can be positioned in the reference position by loosening the bolt and nut mechanisms 61 and 72, and then the upper and lower bolt and nut mechanisms 61 and 72 can be tightened to fix the upper frame 31 in the reference position.

[0037] In the elevator 10 according to this embodiment, the worker 21 performing maintenance and inspection work on the hoisting machine 12 operates the stopper mechanism 40 so that the elevator car 11 does not rise when the brake of the hoisting machine 12 is released and the counterweight 14 pulls it upward. Specifically, before releasing the brake, the worker 21 uses their fingers to pinch the locking bar 54 and rotate and move the stopper pin 43 as appropriate, thereby switching the position in which the locking bar 54 fits from the locking groove 47b to the locking groove 47a. This puts the stopper pin 43 into the through hole 52 of the engaging member 51, that is, the stopper pin 43 and the engaging member 51 are engaged. When the worker 21 releases the brake of the hoisting machine 12 in this state, the tensile load from the counterweight 14 is applied to the elevator car 11.

[0038] <Effects of the Embodiment> In this embodiment, the stopper pin 43 is supported by both the upper frame 31 and the vertical frame 33 via the support member 44, the first fixing bracket 45, and the second fixing bracket 46. Therefore, the tensile load from the counterweight 14 is distributed and applied to both the upper frame 31 and the vertical frame 33. In other words, the tensile load from the counterweight 14 can be borne by both the upper frame 31 and the vertical frame 33. Therefore, deformation of the upper frame 31 can be suppressed compared to the case where the stopper pin 43 is supported only by the upper frame 31. Consequently, when the elevator car 11 is fixed to the guide rail 30 by the stopper mechanism 40, the tensile load from the counterweight 14 can be withstood without increasing the vertical cross-sectional dimension of the upper frame 31 of the elevator car 11. As a result, the height dimension of the car frame 25 and the overhead dimension of the hoistway 16 can be reduced. Furthermore, the vertical cross-sectional dimension of the upper frame 31 can be made the same for elevators 10 equipped with the stopper mechanism 40 and elevators without the stopper mechanism 40, thereby enabling the sharing of parts.

[0039] Furthermore, in this embodiment, the stopper mechanism 40 includes a support member 44 that supports the stopper pin 43 so as to be able to engage and disengage with the engaging member 51, and fixing members (45, 46) that are connected to the support member 44 and fixed to both the upper frame 31 and the vertical frame 33. This allows the tensile load from the counterweight 14 to be transmitted to the upper frame 31 and the vertical frame 33 via the support member 44 and the fixing members (45, 46).

[0040] Furthermore, in this embodiment, the fixing member includes a first fixing bracket 45 fixed to the main surface 31a of the upper frame 31 and the main surface 33a of the vertical frame 33, and a second fixing bracket 46 fixed to the side surface 31b of the upper frame 31 and the side surface 33b of the vertical frame 33. This allows the tensile load from the counterweight 14 to be distributed more evenly between the upper frame 31 and the vertical frame 33 compared to when the fixing member is composed of a single component. In addition, since the first fixing bracket 45 and the second fixing bracket 46 are fixed to different surfaces of the upper frame 31 and the vertical frame 33, it is possible to avoid the concentration of tensile load on a particular surface.

[0041] Furthermore, in this embodiment, the first fixing bracket 45 has a connecting piece 451 that connects to the support member 44 and the vertical frame 33 in the left-right direction and a connecting piece 452 that connects to the upper frame 31 in the up-down direction, and the second fixing bracket 46 has a connecting piece 461 that connects to the support member 44 and the upper frame 31 in the front-rear direction and a connecting piece 462 that connects to the vertical frame 33 in the front-rear direction. As a result, the first fixing bracket 45 and the second fixing bracket 46 can be arranged in a space-saving manner at the connection portion between the upper frame 31 and the vertical frame 33.
