Description

[Technical field]

[0001] The present disclosure relates to a car fixing device. [Background technology]

[0002] Conventionally, a configuration for fixing a car inside a hoistway when replacing an elevator's main rope involves attaching a mounting plate so that it contacts the upper surface of a joint fitting installed at the joint of the guide rail, and suspending the car from the mounting plate via a suspension rope to fix it inside the hoistway (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-186159 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional configurations for fixing cars use joint fittings installed at the joints of the guide rails, which means that the car needs to be moved and stopped based on the position of the joints of the guide rails, which creates the problem that the car cannot be fixed at any desired position.

[0005] In order to solve the above problems, the present disclosure aims to provide a car fixing device that can fix the car at any position. [Means for solving the problem]

[0006] The elevator car fixing device of the present disclosure comprises a frame, a first fixing member attached to one longitudinal end of the frame, and a second fixing member attached to the end opposite the one longitudinal end of the frame, each of the first fixing member and the second fixing member being capable of being fixed to any position in the longitudinal direction of the corresponding guide rail of the elevator by sandwiching the guide rail therebetween, the frame is formed with a pair of hanger mounting portions for mounting corresponding hangers, and when viewed vertically, the frame is formed with an avoidance portion which is a space in the central longitudinal portion. Effect of the Invention

[0007] According to the car fixing device of the present disclosure, the car can be fixed at any position. [Brief description of the drawings]

[Diagram 2] 2 is a schematic diagram showing the car fixing device of FIG. 1 in an exploded state. FIG. [Diagram 3] FIG. 2 is a cross-sectional view taken along line III-III in FIG. [Figure 4] 3 is a schematic view showing a first fixing member of FIG. 2. [Diagram 5] 3 is a schematic view showing a second fixing member of FIG. 2. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Embodiment 1 1 is a schematic diagram showing an elevator 101 in which a car fixing device 1 according to embodiment 1 is installed. The car fixing device 1 is installed between a pair of guide rails 107 of the elevator 101.

[0010] The elevator 101 is installed inside a building 100. The building 100 is formed with an elevator shaft 100a that extends in the vertical direction.

[0011] The elevator 101 has one car 102, an elevator control device 103, a hoist 104, a hoisting rope 106, a pair of guide rails 107, and a counterweight (not shown). One end of the hoisting rope 106 is connected to the car 102, and the other end is connected to the counterweight. The hoisting rope 106 is wound around the hoist 104.

[0012] The elevator control device 103 controls the hoist 104 to move the hoist rope 106, thereby moving the car 102. The car 102 can move in the vertical direction within the hoistway 100a.

[0013] A pair of guide rails 107 are installed in the hoistway 100a along the vertical direction. The pair of guide rails 107 are installed so as to guide the car 102 from both sides.

[0014] When viewed vertically, each guide rail 107 has opposing first and second sides 107a, 107b. Only the first side 107a of each guide rail 107 is visible in FIG.

[0015] The car 102 has a car body 102a, a car frame 102b that supports the car body 102a, a car door 102d, and guide parts (not shown) that hang on each guide rail 107. The car 102 can move within the hoistway 100a along each guide rail 107 because each guide part hangs on the guide rail 107.

[0016] An opening is formed in the car body 102a for users of the elevator 101 to get on and off the car body 102a. The car door 102d can close the opening formed in the car body 102a.

[0017] The car frame 102b is connected with the suspending ropes 106. In the first embodiment, the number of the suspending ropes 106 is three, but the present invention is not limited to this.

[0018] A portion of the car frame 102b disposed above the car body 102a in the horizontal direction across the car body 102a is defined as a beam 102c. The suspending rope 106 is connected to the beam 102c.

[0019] Fig. 2 is a schematic diagram showing an exploded state of the car fixing device 1 of Fig. 1. Fig. 3 is a cross-sectional view showing a cross section along line III-III of Fig. 1. The car fixing device 1 can suspend the car 102 in a state in which the car fixing device 1 is fixed to a pair of guide rails 107. In this explanation, unless otherwise specified, the explanation will be based on a position in which the car fixing device 1 is installed between the pair of guide rails 107.

[0020] The car fixing device 1 includes a frame 10, a first fixing member 20, a second fixing member 30, two link members 40, and a pair of hanging devices 60.

[0021] The frame 10 has a main frame 11, a reinforcing frame 14, and a connecting member 18. The frame 10 has an avoidance portion 12, which is a through hole, formed in the center portion in the longitudinal direction.

[0022] The main frame 11 is a long member. The cross-sectional shape of the main frame 11 is C-shaped. In the main frame 11, a portion having a plane along the vertical direction is referred to as a main frame back portion 11a. A portion having a surface extending continuously from the upper end of the main frame back portion 11a along a horizontal plane is referred to as a main frame upper portion 11b.

[0023] The portion having a surface extending continuously from the lower end of the main frame back portion 11a along the horizontal plane is referred to as the main frame lower portion 11c. The main frame back portion 11a, the main frame upper portion 11b, and the main frame lower portion 11c extend along the longitudinal direction of the main frame 11.

[0024] A main frame upper notch 11d and a main frame lower notch 11e that constitute the avoidance portion 12 are formed in the main frame upper portion 11b and the main frame lower portion 11c, respectively.

[0025] The main frame upper cutout 11d is formed in the main frame upper portion 11b from an end portion not continuing with the main frame back portion 11a toward an end portion continuing with the main frame back portion 11a.

[0026] The main frame lower portion notch 11e is formed in the main frame lower portion 11c from an end portion not continuing with the main frame rear portion 11a toward an end portion continuing with the main frame rear portion 11a.

[0027] A through hole, that is, a main frame upper through hole 11f, is formed on each side of the main frame upper part 11b, which sandwiches the main frame upper cutout 11d in the longitudinal direction of the main frame 11. A through hole, that is, a main frame lower through hole 11g, is formed on each side of the main frame lower part 11c, which sandwiches the main frame lower cutout 11e in the longitudinal direction of the main frame 11.

[0028] The reinforcing frame 14 is a long member. The cross-sectional shape of the reinforcing frame 14 is C-shaped. In the reinforcing frame 14, a portion having a plane along the vertical direction is referred to as the reinforcing frame back portion 14a. A portion having a surface extending horizontally from the upper end of the reinforcing frame back portion 14a is referred to as the reinforcing frame upper portion 14b.

[0029] The portion having a surface extending horizontally from the upper end of the strengthening frame back portion 14a is referred to as the strengthening frame lower portion 14c. The strengthening frame back portion 14a, the strengthening frame upper portion 14b, and the strengthening frame lower portion 14c extend along the longitudinal direction of the strengthening frame 14.

[0030] A reinforcing frame upper notch 14d and a reinforcing frame lower notch 14e that constitute the avoidance portion 12 are formed in the reinforcing frame upper portion 14b and the reinforcing frame lower portion 14c, respectively.

[0031] The reinforcing frame upper cutout 14d is formed in the reinforcing frame upper portion 14b from an end portion not continuous with the reinforcing frame rear portion 14a toward an end portion continuous with the reinforcing frame rear portion 14a.

[0032] The strengthening frame lower cutout 14e is formed in the strengthening frame lower portion 14c from an end portion not continuing with the strengthening frame rear portion 14a toward an end portion continuing with the strengthening frame rear portion 14a.

[0033] Reinforcing frame upper through-holes 14f are formed on both sides of the reinforcing frame upper cutout 14d in the longitudinal direction of the reinforcing frame 14. The reinforcing frame upper through-holes 14f are through-holes.

[0034] Reinforcing frame lower through-holes 14g are formed on both sides of the reinforcing frame lower portion 14c across the reinforcing frame lower cutout 14e in the longitudinal direction of the reinforcing frame 14.

[0035] A hanger attachment portion 14h is formed on each of both sides of the reinforcing frame lower portion 14c that sandwich the reinforcing frame lower cutout 14e in the longitudinal direction of the reinforcing frame 14. Each hanger attachment portion 14h is formed to avoid each reinforcing frame lower through hole 14g. Note that in Fig. 3, the illustration of the hanger attachment portion 14h is omitted, and the hanger attachment portion 14h is shown by a rectangle indicated by a dashed line.

[0036] The connecting members 18 fix the main frame 11 and the reinforcing frame 14 to each other. The connecting members 18 are four sets of bolts and nuts. The main frame 11 and the reinforcing frame 14 are combined along the longitudinal direction and fixed by the connecting members 18.

[0037] The main frame 11 and the reinforcing frame 14 are fixed together with the main frame back portion 11a and the reinforcing frame back portion 14a facing each other. The main frame 11 and the reinforcing frame 14 are fixed together with the main frame upper portion 11b and the reinforcing frame upper portion 14b stacked together and the main frame lower portion 11c and the reinforcing frame lower portion 14c stacked together.

[0038] Each bolt is inserted into the corresponding main frame upper through hole 11f and reinforcing frame upper through hole 14f when main frame upper portion 11b and reinforcing frame upper portion 14b are stacked on top of each other, and fixed with a nut.

[0039] Each bolt is inserted into the corresponding main frame lower through hole 11g and reinforcing frame lower through hole 14g when the main frame lower part 11c and the reinforcing frame lower part 14c are stacked on top of each other, and fixed with a nut.

[0040] When the main frame 11 and the reinforcing frame 14 are fixed and the main frame back portion 11a is arranged vertically, the main frame upper portion 11b is disposed above the reinforcing frame upper portion 14b. When the main frame 11 and the reinforcing frame 14 are fixed and the main frame back portion 11a is arranged vertically, the main frame lower portion 11c is disposed above the reinforcing frame lower portion 14c.

[0041] Therefore, each of the hoist attachment portions 14h is exposed on the lower surface of the frame 10.

[0042] Between the main frame 11 and the reinforcing frame 14, which are fixed to each other, an avoidance portion 12 is formed by an upper main frame notch 11d, a lower main frame notch 11e, an upper reinforcing frame notch 14d, and a lower reinforcing frame notch 14e.

[0043] The first fixing member 20 is attached to one end of the main frame 11, and the second fixing member 30 is attached to the other end opposite the one end of the main frame 11. Figure 4 is a schematic diagram showing the first fixing member 20 of Figure 2.

[0044] In the description of the first fixing member 20, unless otherwise specified, the main frame rear portion 11a is disposed along the vertical direction. Fig. 4 is a view of the first fixing member 20 seen from the outside of the frame 10 along the longitudinal direction of the main frame 11.

[0045] The first fixing member 20 is a rectangular parallelepiped block. A first groove 21 is formed in the first fixing member 20. The first groove 21 is a groove formed along the longitudinal direction of the frame 10 from the outside to the inside of the frame 10.

[0046] That is, the depth direction of the first groove 21 is along the longitudinal direction of the frame 10, and the first groove 21 is formed from the outside toward the inside of the frame 10. The first groove 21 is formed penetrating the first fixing member 20 along the vertical direction from the upper end to the lower end.

[0047] The first groove 21 is formed by a first bottom surface 21a located deep in the depth direction, a first inclined surface 21b continuing to the first bottom surface 21a, and a first vertical surface 21c continuing to the first bottom surface 21a. The first inclined surface 21b and the first vertical surface 21c face each other. The first vertical surface 21c is parallel to a vertical plane along the depth direction.

[0048] When the first groove 21 is viewed in the depth direction, the first inclined surface 21b approaches the first vertical surface 21c as it moves vertically upward. A plane including the first inclined surface 21b intersects with a plane including the first vertical surface 21c at a position vertically upward beyond the first fixing member 20. The intersection line between the first inclined surface 21b and the horizontal plane is a line along the depth direction.

[0049] Fig. 5 is a schematic diagram showing the second fixing member 30 in Fig. 2. In the explanation of the second fixing member 30, unless otherwise specified, the explanation will be given on the condition that the main frame back part 11a is arranged along the vertical direction. Fig. 5 is a view of the second fixing member 30 seen from the outside of the frame 10 along the longitudinal direction of the main frame 11.

[0050] The second fixing member 30 is a rectangular parallelepiped block. A second groove 31 is formed in the second fixing member 30. The second groove 31 is a groove formed along the longitudinal direction of the frame 10 from the outside to the inside of the frame 10.

[0051] That is, the depth direction of the second groove 31 is along the longitudinal direction of the frame 10, and the second groove 31 is formed from the outside to the inside of the frame 10. The second groove 31 is formed penetrating the second fixing member 30 along the vertical direction from the upper end to the lower end.

[0052] The second groove 31 is formed by a second bottom surface 31a located at the back in the depth direction, a second inclined surface 31b continuing to the second bottom surface 31a, and a second vertical surface 31c continuing to the second bottom surface 31a. The second inclined surface 31b and the second vertical surface 31c face each other. The second vertical surface 31c is parallel to a vertical plane along the depth direction.

[0053] When the second groove 31 is viewed in the depth direction, the second inclined surface 31b approaches the second vertical surface 31c as it moves vertically upward. A plane including the second inclined surface 31b intersects with a plane including the second vertical surface 31c at a position beyond the second fixing member 30. The intersection line between the second inclined surface 31b and the horizontal plane is a line along the depth direction.

[0054] 2 and 3, the following description will be given assuming that the main frame back portion 11a is arranged vertically and that the main frame upper portion 11b is placed above the main frame lower portion 11c, unless otherwise specified.

[0055] The first fixing member 20 is attached to the main frame 11 by connecting a surface of the first fixing member 20 facing the surface in which the first groove 21 is formed to one longitudinal end of the main frame 11. The second fixing member 30 is attached to the main frame 11 by connecting a surface of the second fixing member 30 facing the surface in which the second groove 31 is formed to the other longitudinal end of the main frame 11 opposite to the one longitudinal end.

[0056] That is, the first groove 21 and the second groove 31 are each cut from the outside toward the inside in the longitudinal direction of the frame 10. The first vertical surface 21c and the second vertical surface 31c are formed along the longitudinal direction of the frame 10.

[0057] The first vertical surface 21c and the second vertical surface 31c exist in the same plane, that is, in the same vertical plane, that is, the second vertical plane B. Furthermore, each of the first groove 21 and the second groove 31 narrows toward the upper side.

[0058] Each piece 40 is wedge-shaped. Each piece 40 has a vertical surface 40a and an inclined surface 40b that faces the vertical surface 40a. When each piece 40 is arranged with the vertical surface 40a aligned vertically, the intersection of the horizontal plane and the vertical surface 40a and the intersection of the horizontal plane and the inclined surface 40b are parallel to each other.

[0059] Each of the piece members 40 is inserted from below in the vertical direction into each of the first groove 21 and the second groove 31 together with the corresponding guide rails 107. Fixing of the frame 10 to the pair of guide rails 107 will be described later.

[0060] Each hoist 60 has an attachment part 64, a force multiplier part 61 connected below the attachment part 64, a chain 62 passed through the force multiplier part 61 and supported by the force multiplier part 61, and a hook 63 attached to the lower end of the chain 62. The illustration of the hoist 60 is omitted in Fig. 3.

[0061] The mounting portion 64 can be attached to the hanging tool mounting portion 14h. The mounting portion 64 has a hook shape.

[0062] The power-assisting unit 61 has a plurality of gears (not shown). The chain 62 is movable so as to raise or lower the hook 63 through the power-assisting unit 61. An object can be hung from the hook 63 connected to the chain 62.

[0063] The power-assisting unit 61 can pull up an object suspended from a chain 62 passed through the power-assisting unit 61 with little force by combining the gears.

[0064] Each hoist 60 is attached to a corresponding hoist attachment portion 14h on the underside of the lower reinforcing frame portion 14c via an attachment portion 64. When the hoist 60 corresponding to each hoist attachment portion 14h is attached, the load center line G is along the longitudinal direction of the frame 10 and is included in a first vertical plane A, which is the same vertical plane along the vertical direction.

[0065] The load center line G is a straight line including the point of application of the load of the object suspended by the sling 60 attached to each sling attachment portion 14h, and is a line along the vertical direction.

[0066] That is, when the sling 60 is attached to the sling attachment portion 14h and an object is hung from the hook 63, a vertical line including the point at which the load of the object acts on the sling 60 is defined as the load center line G.

[0067] 3 does not show the detailed shape of the hoisting tool attachment portion 14h. For example, the shape of the hoisting tool attachment portion 14h may be U-shaped. The hoisting tool 60 is attached to the hoisting tool attachment portion 14h by hanging the hook portion of the attachment portion 64 on the U-shaped hoisting tool attachment portion 14h.

[0068] A known structure can be applied to the suspending tool attachment portion 14h. Instead of the hook-shaped structure, a screw hole into which an eyebolt for suspending a suspended device can be screwed may be formed.

[0069] In the first embodiment, the load center line G passes through the center of the drawing in a projected diagram of the suspender attachment part 14h as viewed in the vertical direction.

[0070] Next, the car fixing device 1 will be described based on a state in which the frame 10 is fixed between the guide rails 107, that is, a state in which the car fixing device 1 is used to fix the car 102.

[0071] 3 shows a state in which the frame 10 is fixed between the guide rails 107. The first fixed member 20 and the second fixed member 30 are fixed to the corresponding guide rails 107, respectively.

[0072] That is, with the guide rail 107 inserted corresponding to the first groove 21, the piece member 40 is inserted into the first groove 21 from below in the vertical direction. With the guide rail 107 inserted corresponding to the second groove 31, the piece member 40 is inserted into the second groove 31 from below in the vertical direction.

[0073] The shape of the piece member 40 is a wedge shape. When the piece member 40 is inserted from below into each of the first groove 21 and the second groove 31, each piece inclined surface 40b is pressed by the first inclined surface 21b and the second inclined surface 31b, respectively, and the piece member 40 is pressed against the second side surface 107b of the corresponding guide rail 107.

[0074] Furthermore, the first side surface 107a facing the second side surface 107b of each guide rail is pressed against the corresponding first vertical surface 21c and second vertical surface 31c. That is, the corresponding guide rail 107 is sandwiched between the top vertical surface 40a of each top member 40 and the first vertical surface 21c and second vertical surface 31c.

[0075] As a result, the first fixed member 20 and the second fixed member 30 are fixed to the corresponding guide rails 107. The frame 10 is fixed between the pair of guide rails 107 at any position in the longitudinal direction of the guide rails 107.

[0076] An avoidance section 12, which is a space that penetrates in the vertical direction, is formed between the main frame 11 and the reinforcing frame 14. Three hanging ropes 106 pass through the avoidance section 12.

[0077] Next, there will be described a method of using the car fixing device 1 in the elevator 101. The car fixing device 1 is used when stopping and fixing the car 102 at an arbitrary position in the hoistway 100a.

[0078] First, an operator stops the car 102 at an arbitrary position in the hoistway 100a under the control of the elevator control device 103. This position may be a position desired by the operator, for example, a position that takes into consideration workability.

[0079] With the car 102 stopped at a desired position, the worker stands on the ceiling of the car 102 and installs the main frame 11 on the pair of guide rails 107.

[0080] The worker places the main frame 11 between the pair of guide rails 107 so as to insert the guide rails 107 corresponding to the first groove 21 and the second groove 31, respectively. With the main frame 11 placed between the pair of guide rails 107, the worker inserts the link members 40 into the first groove 21 and the second groove 31, respectively.

[0081] At this time, the first groove 21, the second groove 31, the corresponding guide rails 107, and the corresponding piece members 40 are in the following state. The first side surface 107a of the guide rail 107 inserted into the first groove 21 faces and contacts the first vertical surface 21c of the first groove 21. The piece vertical surface 40a of the piece member 40 inserted into the first groove 21 faces and contacts the second side surface 107b of the guide rail 107. The piece inclined surface 40b of the piece member 40 inserted into the first groove 21 faces and contacts the first inclined surface 21b of the first groove 21.

[0082] The first side surface 107a of the guide rail 107 inserted into the second groove 31 faces and contacts the second vertical surface 31c of the second groove 31. The top vertical surface 40a of the piece member 40 inserted into the second groove 31 faces and contacts the second side surface 107b of the guide rail 107. The top inclined surface 40b of the piece member 40 inserted into the second groove 31 faces and contacts the second inclined surface 31b of the second groove 31.

[0083] The worker inserts the piece member 40 into the first groove 21 until the guide rail 107 is firmly sandwiched between the piece vertical surface 40a of the piece member 40 and the first vertical surface 21c of the first groove 21. Similarly, the worker inserts the piece member 40 into the second groove 31 until the guide rail 107 is firmly sandwiched between the piece vertical surface 40a of the piece member 40 and the second vertical surface 31c of the second groove 31.

[0084] As a result, the frame 10 is fixed between the pair of guide rails 107 at any position in the longitudinal direction of the pair of guide rails 107. In this state, the reinforcing frame 14 is not combined with the main frame 11.

[0085] Next, the worker assembles the main frame 11 with the reinforcing frame 14 so that the suspension rope 106 is sandwiched between the main frame 11 and the reinforcing frame 14 .

[0086] The worker fixes together the main frame 11 and the reinforcing frame 14, which are combined with the connecting members 18. In this state, the suspending rope 106 passes through the avoidance section 12 formed between the frame 10 and the reinforcing frame 14, and the suspending rope 106, the frame 10, and the reinforcing frame 14 do not interfere with each other.

[0087] The worker attaches the mounting parts 64 of the hoisting tool 60 corresponding to each hoisting tool mounting part 14h, and attaches each hoisting tool 60 to the frame 10. Thereafter, the hooks 63 of each hoisting tool 60 are connected to corresponding lifting points (not shown) provided on the beam 102c.

[0088] Typically, the beam 102c is provided with a lifting point as a point for lifting the cage 102 in order to suspend and secure the cage 102 by something other than the lifting rope 106. Specifically, a hook-shaped member is provided on the upper surface of the beam 102c as the lifting point.

[0089] In the present embodiment 1, at least two lifting points are provided to correspond to each of the lifting tools 60 provided on the car fixing device 1. An operator uses each of the force multipliers 61 to pull up the corresponding chain and apply an appropriate tension to the chain 62.

[0090] As a result, the car fixing device 1 is in a state where it suspends the car 102 at any position desired by the worker. That is, the car 102 is stopped at any position by using the car fixing device 1. In this state, even if the suspending rope 106 is removed from the car 102, the car 102 will not fall.

[0091] Usually, in elevator 101, each guide rail 107 and hanging rope 106 are installed so that the center of the thickness direction of each guide rail 107 and the center of hanging rope 106 are arranged on the same straight line when viewed vertically. Here, the thickness of guide rail 107 is the thickness between first side surface 107a and second side surface 107b.

[0092] Furthermore, when viewed from the vertical direction, each lifting point is disposed with respect to the beam 102c so that the center of each lifting point and the center of the lifting rope 106 are on the same straight line. That is, the center of each lifting point, the center of the lifting rope 106, and the center in the thickness direction of the pair of guide rails 107 are on the same vertical plane.

[0093] With the car fixing device 1 fixed between the pair of guide rails 107, the first vertical plane A includes the center of the pair of guide rails 107 in the thickness direction. That is, the first vertical plane A includes the center of the lifting point, the center of the lifting rope 106, and the center of the pair of guide rails 107 in the thickness direction.

[0094] The first vertical plane A is a plane including the center of the guide rail 107 in the thickness direction. On the other hand, the second vertical plane B is a plane that contacts the first side surface 107a of the guide rail 107, and therefore the first vertical plane A and the second vertical plane B are not the same plane. The distance between the first vertical plane A and the second vertical plane B is half the thickness of the guide rail 107.

[0095] When viewed in the vertical direction, the shape of the frame 10 is such that it avoids an avoidance portion 12, which is a space including a first vertical plane A, in the central portion of the frame 10 in the longitudinal direction.

[0096] According to the car fixing device 1 of the first embodiment, the car fixing device 1 includes a frame 10, a first fixing member 20 attached to one end of the frame 10 in the longitudinal direction, and a second fixing member 30 attached to the end of the frame 10 opposite to the one end in the longitudinal direction. Each of the first fixing member 20 and the second fixing member 30 can be fixed to any position in the longitudinal direction of the guide rail 107 of the elevator 101 by sandwiching the corresponding guide rail 107. The frame 10 is also formed with a pair of hoisting attachment parts 14h for attaching the corresponding hoisting device 60. When viewed from the vertical direction, the frame 10 is also formed with an avoidance part 12, which is a space, in the central part in the longitudinal direction. This allows each of the first fixing member 20 and the second fixing member 30 to be attached to any position of the pair of guide rails 107. Therefore, the position of the car 102 suspended from the car fixing device 1 attached to any position of the pair of guide rails 107 can also be any position of the pair of guide rails 107. Therefore, the car 102 can be fixed at any position.

[0097] According to the car fixing device 1 of the first embodiment, when the hoisting tools 60 corresponding to each hoisting tool attachment portion 14h are attached, a line along the vertical direction including the point of application of the hanging load to the hoisting tool 60 is set as the load center line G of each hoisting tool attachment portion 14h. In this case, each load center line G is included in the first vertical plane A, which is the same plane along the longitudinal direction of the frame 10 and along the vertical direction. As a result, the points of application of the hanging load to the frame 10 are each located at an equal distance from the frame 10. Therefore, when each of the pair of hoisting tools 60 hoists an object, an equal load is applied to the frame 10 from each hoisting tool 60, and distortion of the frame 10 can be suppressed.

[0098] According to the car fixing device 1 of the first embodiment, when the frame 10 is fixed between a pair of guide rails 107, the center of the hoisting rope 106 exists on the first vertical plane A when viewed along the vertical direction. As a result, the lifted portion of the car 102 suspended by the hoisting rope 106 under normal circumstances also exists on the first vertical plane A. That is, the lifted portion of the car 102 suspended by the hoisting rope 106 under normal circumstances and each load center line G exist on the same plane. Therefore, since the portion on the same plane as the lifted portion of the car 102 under normal circumstances is suspended by the pair of hoisting tools 60, distortion of the car 102 can be suppressed.

[0099] According to the car fixing device 1 according to the first embodiment, when the frame 10 is fixed between the pair of guide rails 107, the suspension ropes 106 pass through the avoidance section 12. As a result, even when the car fixing device 1 is installed, there is no interference with the suspension ropes 106.

[0100] According to the car fixing device 1 according to the first embodiment, the first fixing member 20 is formed with a first vertical surface 21c that faces and contacts the first side surface 107a of the guide rail 107, and the second fixing member 30 is formed with a second vertical surface 31c that faces and contacts the first side surface 107a of the guide rail 107. The first vertical surface 21c and the second vertical surface 31c are included in a second vertical plane B that is the same plane along the longitudinal direction of the frame 10 and along the vertical direction. As a result, when the frame 10 is fixed between the pair of guide rails 107, the first vertical surface 21c, the second vertical surface 31c, and the first side surface 107a of each guide rail 107 are present in the second vertical plane B that is the same plane along the longitudinal direction of the frame 10. Therefore, the frame 10 does not come into contact with each guide rail 107 in an unbalanced manner. Therefore, the frame 10 can be stably fixed to each guide rail 107.

[0101] According to the car fixing device 1 according to the first embodiment, the first fixing member 20 is formed with a first groove 21 penetrating the first fixing member 20 in the vertical direction, and the second fixing member 30 is formed with a second groove 31 penetrating the second fixing member 30 in the vertical direction. In addition, one surface of the first groove 21 along the longitudinal direction of the frame 10 is a first vertical surface 21c, and one surface of the second groove 31 along the longitudinal direction of the frame 10 is a second vertical surface 31c. In addition, the corresponding guide rails 107 are inserted and fixed into the first groove 21 and the second groove 31. As a result, the frame 10 does not come into contact with each guide rail 107 inserted into the first groove 21 and the second groove 31 in a biased manner. Therefore, the frame 10 can be stably fixed to each guide rail 107.

[0102] According to the cage fixing device 1 according to the first embodiment, a pair of frame members 40 are further provided, and each frame member 40 has a wedge shape. In addition, by inserting the frame member 40 into the first groove 21 and the second groove 31 from the vertically lower side, respectively, in a state in which the guide rails 107 corresponding to the first groove 21 and the second groove 31 are inserted, the first fixing member 20 and the second fixing member 30 can be fixed to the corresponding guide rails 107. As a result, the first fixing member 20 and the second fixing member 30 can be fixed more firmly to the corresponding guide rails 107 by the wedge-shaped frame member 40. Furthermore, since the frame member 40 has a wedge shape, the frame 10 can be fixed more firmly to the guide rails 107 by utilizing the vertically downward force applied to the frame 10.

[0103] The car fixing device 1 according to the first embodiment further includes a pair of suspenders 60. This makes it possible to select suspenders 60 of similar shape and quality and use the suspenders 60. This makes it possible to suspend the car 102 more stably.

[0104] According to the car fastening device 1 of the first embodiment, the frame 10 has the main frame 11 and the reinforcing frame 14 fixed to the main frame 11. This makes it possible to increase the strength of the frame 10.

[0105] According to the car fixing device 1 of the first embodiment, when the reinforcing frame 14 is fixed to the main frame 11, the avoidance portion 12 is formed between the main frame 11 and the reinforcing frame 14 when viewed in the vertical direction. This allows the frame 10 to be fixed between the pair of guide rails 107 without interfering with the hanging ropes 106.

[0106] In the car fixing device 1 according to the first embodiment, the cross-sectional shape of the main frame 11 is a C-shape. However, this is not limited to this. As long as the main frame 11 has the necessary structural strength, the main frame 11 may have any shape.

[0107] In the car fixing device 1 according to the first embodiment, the cross-sectional shape of the reinforcing frame 14 is a C-shape. However, this is not limited to this. As long as the reinforcing frame 14 has the necessary structural strength, the reinforcing frame 14 may have any shape.

[0108] Moreover, the car fastening device 1 according to the first embodiment is provided with a pair of suspenders 60. However, this is not limited to this. For example, even if the car fastening device 1 does not have a pair of suspenders 60, well-known equipment and tools for suspension can be attached to each of the suspender attachment portions 14h for use. This allows the use of well-known equipment for suspension that is also used for other work, improving convenience at the work site.

[0109] Moreover, the car fixing device 1 according to the first embodiment is provided with a reinforcing frame 14. However, this is not limited to this. If the frame 10 has the structural strength required to hoist and stop the car 102, the reinforcing frame 14 does not have to be provided. If the reinforcing frame 14 is not provided, each hoisting device 60 is attached to the main frame 11. In other words, each hoisting device mounting portion 14h is provided on the frame 10, and the hoisting devices 60 attached to each hoisting device mounting portion 14h may take any form as long as they do not interfere with other members.

[0110] In addition, in the cage fixing device 1 according to the first embodiment, the hoist 60 corresponding to the hoist attachment portion 14h provided on the reinforcing frame 14 is attached. However, this is not limited to this. For example, the hoist attachment portion 14h may be provided on the main frame 11, and a pair of hoisting devices 60 may be attached to the hoist attachment portion 14h. In this case, the reinforcing frame lower portion 14c may be disposed vertically above the main frame lower portion 11c, and each hoisting device 60 may be attached to the lower surface of the main frame lower portion 11c, so that the pair of hoisting devices 60 attached to the main frame 11 do not interfere with the reinforcing frame 14. In other words, each hoist attachment portion 14h is provided on the frame 10, and the hoisting devices 60 attached to each hoist attachment portion 14h may take any form as long as they do not interfere with the members constituting the frame 10.

[0111] In addition, in the cage fixing device 1 according to the first embodiment, the frame 10 is fixed to the guide rail 107 using the first fixing member 20, the second fixing member 30, and a pair of wedge-shaped block members 40. However, this is not limited to this. Each fixing member may be fixed to the guide rail 107 without using the block members 40. For example, a through screw hole reaching the first groove 21 and the second groove 31 from the outside may be formed in each of the first fixing member 20 and the second fixing member 30, and the guide rail 107 inserted in the first groove 21 and the second groove 31 may be tightened by screwing a bolt into the screw hole. As a result, the first side surface 107a of each guide rail 107 is pressed against the first vertical surface 21c and the second vertical surface 31c, that is, each guide rail 107 may be sandwiched and fixed between each bolt and the first vertical surface 21c and the second vertical surface 31c. Furthermore, a member having a high friction surface may be pressed against the guide rail 107 inserted into the first groove 21 and the second groove 31, thereby sandwiching and fixing the guide rail 107.

[0112] Moreover, the car fixing device 1 according to the first embodiment includes a connecting member 18 that is a bolt and a nut. However, this is not limited to this. Any known mechanism can be used for the connecting member 18 as long as it can fix the main frame 11 and the reinforcing frame 14 to each other.
