Summary of the Invention

Problems to be Solved by the Invention

[0004] However, with the rotating jig described in Patent Document 1, for example, it is not possible to horizontally move heavy objects such as couplers provided on Shinkansen vehicles. In view of this point, the present disclosure discloses an example of a moving device for horizontally moving heavy objects such as couplers.

Means for Solving the Problems

[0005] The moving device for horizontally moving an object preferably includes, for example, the following constituent elements. That is, the constituent elements include a rack (12), a detent (18) displaceable between an engagement position engaging with the tooth portion (12A) of the rack (12) and a release position where the engagement is released, a slide member (14) to which the detent (18) is connected and which is slidably displaceable in a direction parallel to the longitudinal direction of the rack (12), a rotating body (23) rotatably connected to the slide member (14) and having a rotation center axis (Lo) parallel to the tooth flanks direction of the tooth portion (12A), a connecting portion (24) provided on the rotating body (23) to which a connected portion (2A) provided on an object is connected, the connected portion (2A) being detachably and rotatably connected about an axis parallel to the rotation center axis (Lo), and an operation lever (16) connected to the rotating body (23) and swung by an operator, the operation lever (16) applying a rotational force about an axis parallel to the rotation center axis (Lo) to the rotating body (23).

[0006] And it is desirable that at least one of the tooth portion (12A) and the detent (18) is provided with an inclined surface (h1) that generates a force to displace the detent (18) toward the release position when a force in one direction in the slide direction acts on the detent (18) in a state where the tooth portion (12A) and the detent (18) are engaged with each other.

[0007] Thereby, when a force in the other direction in the slide direction acts on the detent (18) in a state where the detent (18) is in the engagement position, the slide displacement of the slide member (14) is restricted. That is, the slide member (14) does not displace in the other direction in the slide direction.

[0008] When the operator operates the operation lever (16) in the first direction, the rotating body (23) rotates about the rotation center axis (Lo) which is the connection point with the slide member (14). For this reason, the connecting portion (24) provided on the rotating body (23) also rotates and displaces about the rotation center axis (Lo).

[0009] At this time, since the rotation center axis (Lo) of the rotating body (23) is parallel to the tooth direction of the rack (12), when the rotating body (23) rotates about the connection point with the slide member (14), the connecting portion (24) is displaced toward one side in the longitudinal direction of the rack (12).

[0010] Also, when the operator operates the operation lever (16) in the opposite direction to the above case, that is, in the second direction, a unidirectional force in the slide direction acts on the detent (18). For this reason, since the detent (18) is displaced toward the release position side, the rotational force input to the rotating body (23) via the operation lever (16) becomes a rotational force that rotates the rotating body (23) about the connecting portion (24).

[0011] That is, when the detent (18) is displaced toward the release position side, the connection point between the rotating body (23) and the slide member (14) becomes in a slidable displacement state. On the other hand, the frictional resistance when the object is slidably displaced is sufficiently larger than the frictional resistance when the slide member (14) is slidably displaced.

[0012] Therefore, when the operation lever (16) is operated in the second direction, the rotational force input to the rotating body (23) via the operation lever (16) becomes a rotational force that rotates the rotating body (23) about the connecting portion (24).

[0013] And since the object and the connecting portion (24) are rotatably connected about an axis parallel to the rotation center axis (Lo), when the rotating body (23) rotates about the connecting portion (24), the connection point between the rotating body (23) and the slide member (14) is displaced in the longitudinal direction of the rack (12).

[0014] At this time, since the operation lever (16) is operated in the second direction, the rotating body (23) rotates in the opposite direction to when the operation lever (16) is operated in the first direction. However, since the rotating body (23) rotates about the connecting portion (24), when the operation lever (16) is operated in the second direction, the detent (18) is displaced toward one side in the longitudinal direction of the rack (12).

[0015] Therefore, in the moving device, when an operator reciprocally swings the operation lever (16), "the connecting portion (24) is displaced toward one side in the longitudinal direction of the rack (12)" → "the detent (18) is displaced toward one side in the longitudinal direction of the rack (12)" → "the connecting portion (24) is displaced toward one side in the longitudinal direction of the rack (12)" → "the detent (18) is displaced toward one side in the longitudinal direction of the rack (12)" → ······ and it operates.

[0016] That is, in the moving device, every time the operation lever (16) is operated in the first direction, the object moves parallel toward one side in the longitudinal direction of the rack (12), and every time the operation lever (16) is operated in the second direction, the slide member (14) and the detent (18) move parallel toward one side in the longitudinal direction of the rack (12).

[0017] Incidentally, the reference numerals in each of the above parentheses are an example showing the correspondence with the specific configuration and the like described in the embodiments described later, and the present disclosure is not limited to the specific configuration and the like indicated by the reference numerals in the above parentheses.

Mode for Carrying Out the Invention

[0019] The following "Embodiments of the Invention" show an example of embodiments belonging to the technical scope of the present disclosure. That is, the invention-specific matters described in the claims are not limited to the specific configurations and structures shown in the following embodiments.

[0020] Note that the arrows, hatches, etc. indicating directions attached to each figure are described to facilitate understanding of the relationship between the figures and the shapes of each member or part. Therefore, the invention disclosed in the present disclosure is not limited to the directions attached to each figure.

[0021] At least one member or part described with a reference sign is provided, unless otherwise specified such as "one". The moving device disclosed herein includes at least one component such as a member or part described with a reference sign, and at least one of the illustrated structural parts.

[0022] (First Embodiment) <1. Development Background of the Moving Device> In this embodiment, an example of the moving device according to the present disclosure is applied to a moving device for translating the coupler 2 shown in FIG. 1. The coupler 2 is a coupler for vehicle connection provided at the front end of the leading car or the last car of the Shinkansen vehicle 1.

[0023] Note that the coupler 2 is covered by a conical "front large hood" (not shown) during normal commercial operation. When connecting the coupler 2 to the coupler of another vehicle, the operator first removes the front large hood.

[0024] Next, the operator translates the coupler 2 toward the coupler side of the other vehicle (see the arrow in FIG. 1) in parallel to connect the other coupler and the coupler 2. Note that the coupler 2 has a strength capable of towing a 16-car Shinkansen.

[0025] Therefore, since the mass of the coupler 2 is extremely large, it is practically impossible for a single operator to manually move the coupler 2. The moving device according to this embodiment has been developed and manufactured in view of this point.

[0026] <2. Configuration of the Moving Device> As shown in FIG. 3, the moving device 10 according to this embodiment includes at least a frame 11, a first rack 12, a second rack 13, a slide member 14, a reciprocating mechanism 15, an operation lever 16, and a fixing device 17.

[0027] <Frame> As shown in FIG. 4, the frame 11 is a member to which the first rack 12 and the second rack 13 are fixed. One end side in the longitudinal direction of the frame 11 is fixed to a Shinkansen vehicle when the moving device 10 is used, as shown in FIG. 5.

[0028] Therefore, as shown in FIG. 3, a fixing device 17 is provided at one end side in the longitudinal direction of the frame 11 (the right end side in FIG. 3). Note that the frame 11 according to the present embodiment is formed by connecting a first frame 11A and a second frame 11B via a hinge portion 11C, as shown in FIG. 6.

[0029] Therefore, for example, when the moving device 10 is not in use, as shown in FIG. 7, an operator can fold the frame 11 at the hinge portion 11C and store and preserve it. A locking tool 11D is provided on the frame 11.

[0030] As shown in FIG. 6, the locking tool 11D is a connection holding tool for maintaining a state in which the first frame 11A and the second frame 11B are linearly connected. Note that the locking tool 11D according to the present embodiment is a gasket plate-shaped member that sandwiches the first frame 11A and the second frame 11B from above and below.

[0031] <The first rack, the second rack> The first rack 12 and the second rack 13 cooperate with the slide member 14 and the advancing and retreating mechanism 15 to constitute a ratchet mechanism. As shown in FIG. 8, the first rack 12 and the second rack 13 have a large number of tooth portions 12A and 13A. These tooth portions 12A and 13A are arranged in series along the longitudinal direction of the frame 11.

[0032] Each of the tooth portions 12A and 13A is configured in a substantially right-angled triangle shape. Note that each of the tooth portions 12A and 13A according to the present embodiment is not a perfect right-angled triangle. As shown in FIG. 9, the length of the first inclined surface h1 is longer than the length of the second inclined surface h2, and the angle θ formed by the second inclined surface h2 and the bottom surface bo is larger than 90 degrees.

[0033] In the first rack 12, as shown in FIG. 8, the first inclined surface h1 is located on the side of the fixing device 17 (the right side in FIG. 8) with respect to the second inclined surface h2. In the second rack 13, the second inclined surface h2 is located on the side of the fixing device 17 (the right side in FIG. 8) with respect to the first inclined surface h1. That is, the direction of the teeth of the second rack 13 is opposite to the direction of the teeth of the first rack 12.

[0034] <Slide member> The slide member 14 is a member guided by the frame 11 and slidable along the longitudinal direction of the frame 11. Therefore, as shown in FIG. 3, guide members 11E and 11F are provided at one end side and the other end side in the width direction of the frame 11.

[0035] The guide members 11E and 11F are portions configured in a substantially U-shape or a substantially C-shape, and slidably contact the slide member 14 so as to sandwich the slide member 14 from above and below. Therefore, the displacement of the slide member 14 in the width direction and the vertical direction is restricted.

[0036] Note that the width direction is the direction orthogonal to the longitudinal direction and the vertical direction of the frame 11 in a state where the moving device 10 is fixed to the Shinkansen vehicle. Hereinafter, the longitudinal direction of the frame 11 is also referred to as the slide direction.

[0037] <Advance and retreat mechanism> As shown in FIG. 10, the advance and retreat mechanism 15 is configured to include at least a first tooth stopper 18, a second tooth stopper 19, a first spring 20, a second spring 21, a switching mechanism 22, a bar holding portion 23, and the like.

[0038] <First tooth stopper> The first tooth stopper 18 is a member engageable with the tooth portion 12A of the first rack 12. The first tooth stopper 18 is displaceable between an engagement position (see FIG. 10) where it engages with the tooth portion 12A and a release position (see FIG. 13) where the engagement is released.

[0039] That is, as shown in FIG. 11, at least one (a plurality in this embodiment) protrusion 18A is provided on the first stopper 18 according to this embodiment. The plurality of protrusions 18A are arranged in series along the sliding direction.

[0040] At least one of the plurality of protrusions 18A has inclined surfaces h3 and h4 and is configured in a shape substantially similar to the tooth portion 12A of the first rack 12. Note that the inclined surface h3 corresponds to the first inclined surface h1, and the inclined surface h4 corresponds to the second inclined surface h2.

[0041] The first stopper 18 according to this embodiment is displaced between an engaged position and a released position by swinging in the vertical direction about a shaft portion 18B provided on one side in the sliding direction (the left end side of the first stopper 18 in FIG. 10).

[0042] When the first stopper 18 is in the engaged position, as shown in FIG. 10, the inclined surface h3 faces the first inclined surface h1, and the inclined surface h4 faces the second inclined surface h2, so that the tooth portion 12A and the first stopper 18 are in a meshed state.

[0043] When a force in one direction in the sliding direction (leftward in FIG. 10) acts on the first stopper 18, a force (hereinafter referred to as a release force) for displacing the first stopper 18 toward the release position side is generated on the contact surface between the inclined surface h3 of the protrusion 18A and the first inclined surface h1 of the tooth portion 12A.

[0044] On the other hand, when a force in the other direction in the sliding direction (rightward in FIG. 10) acts on the first stopper 18, no release force is generated on the contact surface between the inclined surface h4 of the protrusion 18A and the second inclined surface h2 of the tooth portion 12A. Note that the first spring 20 exerts an elastic force for holding the first stopper 18 in the engaged position (see FIG. 12).

[0045] <Second stopper> As shown in FIG. 13, the second detent 19 has a configuration substantially symmetric to the first detent 18. That is, the second detent 19 is a member engageable with the tooth portion 13A of the second rack 13. The second detent 19 is displaceable between an engagement position (see FIG. 13) where it engages with the tooth portion 13A and a release position (see FIG. 10) where the engagement is released.

[0046] As shown in FIG. 11, the second detent 19 according to the present embodiment is provided with at least one (a plurality in the present embodiment) protrusion 19A. The plurality of protrusions 19A are arranged in series along the sliding direction.

[0047] At least one of the plurality of protrusions 19A has inclined surfaces h3 and h4 and is configured in a shape substantially similar to the tooth portion 13A of the second rack 13. Note that the inclined surface h3 corresponds to the first inclined surface h1, and the inclined surface h4 corresponds to the second inclined surface h2.

[0048] The second detent 19 according to the present embodiment is displaced between the engagement position and the release position by swinging in the vertical direction about a shaft portion 19B provided on the other side in the sliding direction (the right end side of the second detent 19 in FIG. 13).

[0049] When the second detent 19 is in the engagement position, as shown in FIG. 13, the inclined surface h3 faces the first inclined surface h1, and the inclined surface h4 faces the second inclined surface h2, so that the tooth portion 13A and the second detent 19 are in a meshed state.

[0050] Then, when a force in the other direction in the sliding direction (rightward in FIG. 13) acts on the second detent 19, a force for displacing the second detent 19 toward the release position, that is, a release force, is generated on the contact surface between the inclined surface h3 of the protrusion 19A and the first inclined surface h1 of the tooth portion 13A.

[0051] On the other hand, when a unidirectional force in the sliding direction (leftward in FIG. 13) acts on the second stopper 19, a release force does not occur at the contact surface between the inclined surface h4 of the protrusion 19A and the second inclined surface h2 of the tooth portion 13A. Note that the second spring 21 exerts an elastic force for holding the second stopper 19 in the engaged position.

[0052] <Switching mechanism> The switching mechanism 22 is a mechanism capable of holding either one of the first stopper 18 and the second stopper 19 in the release position. Specifically, the switching mechanism 22 is a mechanism for selectively switching among a drawer mode, a push-in mode, and a neutral mode.

[0053] In the drawer mode, the second stopper 19 is held in the release position, and the first stopper 18 becomes displaceable. In the push-in mode, the first stopper 18 is held in the release position, and the second stopper 19 becomes displaceable. In the neutral mode, the first stopper 18 and the second stopper 19 are held in the release position.

[0054] As shown in FIG. 14, the switching mechanism 22 is configured to include at least a first driven joint 22A, a first direct-acting cam 22B, a second driven joint 22C, a second direct-acting cam 22D, a connecting member 22E, and an operation portion 22F.

[0055] As shown in FIG. 15, the first driven joint 22A is a cam follower that is displaced integrally with the first stopper 18. The first direct-acting cam 22B is a driving joint that displaces the first driven joint 22A by displacing while slidingly contacting the first driven joint 22A.

[0056] The second driven joint 22C is a cam follower that is displaced integrally with the second stopper 19. The second direct-acting cam 22D is a driving joint that displaces the second driven joint 22C by displacing while slidingly contacting the second driven joint 22C.

[0057] The connecting member 22E connects the first linear cam 22B and the second linear cam 22D, and linearly reciprocates them in conjunction with each other. The operation portion 22F transmits the operator's operating force to the connecting member 22E.

[0058] When the first linear cam 22B and the second linear cam 22D are in the positions shown in FIG. 10, the pulling-out mode is entered. When the first linear cam 22B and the second linear cam 22D are in the positions shown in FIG. 13, the pushing-in mode is entered. When the first linear cam 22B and the second linear cam 22D are in the positions shown in FIG. 16, the neutral mode is entered.

[0059] <Bar holding portion> As shown in FIG. 14, the bar holding portion 23 is an example of a rotating body rotatably connected to the slide member 14. The rotation center axis Lo (see FIG. 11) of the bar holding portion 23 is parallel to the tooth row direction of the tooth portion 12A of the first rack 12. The tooth row direction of the tooth portion 12A is the ridge direction connecting the tops of the tooth portion 12A.

[0060] A connecting portion 24 is provided on the bar holding portion 23. The connected portion 2A (see FIG. 2) provided on the connector 2 is connected to the connecting portion 24. The connected portion 2A is a horizontally extending rod-shaped member integrated with the connector 2 as shown in FIG. 2.

[0061] The connected portion 2A is detachably and rotatably connected to the connecting portion 24. Specifically, the connected portion 2A connected to the connecting portion 24 is rotatable about an axis L1 parallel to the rotation center axis Lo.

[0062] As shown in FIG. 17, the connecting portion 24 has at least a main body portion 24A, a cover portion 24B, a lock pin 24C, etc. The main body portion 24A is a portion provided with a U-shaped groove portion into which the connected portion 2A can be fitted.

[0063] The cover part 24B prevents the connected part 2A fitted into the main body part 24A from coming out. The cover part 24B is displaceable between a position where the upper part of the groove is open (see Fig. 17) and a position where the upper part of the groove is closed (see Fig. 18).

[0064] The lock pin 24C is a locking part for holding the cover part 24B in a closed position (hereinafter referred to as the closed position). That is, the lock pin 24C is constantly pressed toward the inner center of the groove by a spring (not shown).

[0065] The cover part 24B is provided with a hole (not shown) into which the lock pin 24C can be fitted. The hole is provided at a part where the lock pin 24C can be fitted when the cover part 24B is in the closed position.

[0066] Therefore, when the position of the cover part 24B reaches the closed position, the lock pin 24C is fitted into the above hole by the elastic force of the spring, so that the cover part 24B is held in the closed position. Accordingly, the state where the connected part 2A is connected to the connecting part 24 is maintained.

[0067] <Operating lever> As shown in Fig. 10, the operating lever 16 is a member that is connected to the bar holding part 23 and is swung by an operator. That is, the operating lever 16 is an operating member for applying a rotational force about an axis parallel to the rotation center axis Lo to the bar holding part 23.

[0068] Note that the operating lever 16 according to the present embodiment is connected to the bar holding part 23 at a position shifted to the connecting part 24 side with respect to the connecting position (rotation center axis Lo) between the bar holding part 23 and the slide member 14.

[0069] <Fixing device> The fixing device 17 is a device for sandwiching the front end wall 2B (see FIG. 2) of the snowplow device of the Shinkansen vehicle and fixing the frame 11 to the front end wall 2B of the snowplow device. As shown in FIG. 19, the fixing device 17 includes a first pressing body 17A, a second pressing body 17B, a base plate 17C, cams 17D, 17E, an operation link mechanism 17F, and the like.

[0070] The first pressing body 17A is a member that can be displaced between a clamping position (see FIG. 19) and a non-clamping position (see FIG. 20). The second pressing body 17B is a member that is disposed at a position facing the first pressing body 17A via a space and is fixed to the base plate 17C.

[0071] The first pressing body 17A is supported by the base plate 17C so as to be displaceable. The second pressing body 17B is integrated and fixed to the base plate 17C. The base plate 17C is the substrate of the fixing device 17.

[0072] As shown in FIG. 19, the clamping position is a position where the first pressing body 17A and the second pressing body 17B contact the front end wall 2B of the snowplow device, and the first pressing body 17A and the second pressing body 17B cooperate to sandwich the front end wall 2B of the snowplow device.

[0073] As shown in FIG. 20, the non-clamping position is a position where the first pressing body 17A is separated from the front end wall 2B of the snowplow device, or a position where the first pressing body 17A contacts the front end wall 2B of the snowplow device with a substantially zero contact surface pressure.

[0074] The first pressing body 17A according to the present embodiment is configured by a leaf spring-shaped member that is curved in an arc shape so as to be convex toward the second pressing body 17B. And an elastic part (not shown) is provided at a part of the first pressing body 17A that contacts the front end wall 2B of the snowplow device.

[0075] The elastic part is made of an elastic material such as hard rubber, for example. The base plate 17C connects the fixing device 17 and the frame 11 and holds the first pressing body 17A and the second pressing body 17B.

[0076] Cams 17D and 17E hold first pressing body 17A in the clamping position. Cams 17D and 17E rotate to switch between a state in which first pressing body 17A is held in the clamping position and a state in which first pressing body 17A is allowed to move to the non-pressing position.

[0077] The operation link mechanism 17F is an example of an operation unit operated by an operator, and is a link mechanism for rotating the cams 17D and 17E. Specifically, as shown in Fig. 3, the operation link mechanism 17F includes an operation handle 17H and a link mechanism 17J.

[0078] As shown in Figure 19, link mechanism 17J has multiple link bars and converts the rotation of operating handle 17H into rotation of cams 17D and 17E. Furthermore, link mechanism 17J rotates cam 17D and cam 17E in opposite directions when activated. That is, when cam 17D rotates to the right, cam 17E rotates to the left. When cam 17D rotates to the left, cam 17E rotates to the right.

[0079] Cams 17D and 17E are configured to have a substantially elliptical or triangular shape. When cams 17D and 17E are in the clamping position, the major axis of cams 17D and 17E is inclined with respect to the wall surface of second pressing body 17B, and first pressing body 17A is elastically deformed.

[0080] 3. Features and Operation of the Moving Device According to the Present Embodiment <3.1 When coupler 2 is moved parallel to the direction of the arrow in Figure 1> The worker uses the fixing device 17 of the moving device 10 to fix the moving device 10 to the front end wall 2B of the obstacle deflector, and then connects the connected part 2A to the connecting part 24.

[0081] Next, the operator sets the switching mechanism 22 to the pull-out mode and then operates the operating lever 16 in the first direction (see the arrow in FIG. 21), which causes a force to act on the first pawl 18 in the other sliding direction (to the right in FIG. 21).

[0082] At this time, since the first stopper 18 is in the engaged position, the sliding displacement of the slide member 14 is restricted, so the bar holding portion 23 rotates counterclockwise (leftward) about the rotation center axis Lo which is the connection point with the slide member 14. Therefore, the connecting portion 24 provided on the bar holding portion 23 also rotates leftward.

[0083] And since the rotation center axis Lo of the bar holding portion 23 is parallel to the tooth row direction of the first rack 12, when the bar holding portion 23 rotates leftward about the rotation center axis Lo, the connecting portion 24 is displaced to one side in the longitudinal direction of the first rack 12 (the left side in FIG. 21).

[0084] Incidentally, the connecting portion 24 is displaced to the left so as to draw an arc about the rotation center axis Lo, while the connected portion 2A moves in a substantially straight line parallel. This is because the connected portion 2A can also be displaced in the vertical direction with respect to the connecting portion 24.

[0085] Also, when the operator operates the operation lever 16 in the opposite direction to the above case, that is, in the second direction (see the arrow in FIG. 22), a force in the other direction of the sliding direction (leftward in FIG. 22) acts on the first stopper 18, so a releasing force acts on the first stopper 18.

[0086] Therefore, since the first stopper 18 is displaced to the release position, the rotational force input to the bar holding portion 23 via the operation lever 16 becomes a rotational force that rotates the bar holding portion 23 clockwise (rightward) about the connecting portion 24.

[0087] That is, when the first stopper 18 is displaced to the release position side, the slide member 14 becomes in a state where it can slide. On the other hand, the frictional resistance when the coupler 2 slides is sufficiently large compared to the frictional resistance when the slide member 14 slides.

[0088] Therefore, when the operation lever 16 is operated in the second direction, the rotational force input to the bar holding portion 23 via the operation lever 16 becomes a rotational force that rotates the bar holding portion 23 clockwise (rightward) about the connecting portion 24.

[0089] And since the coupler 2 and the connecting portion 24 are rotatably connected about an axis parallel to the rotation center axis Lo, when the bar holding portion 23 rotates rightward about the connecting portion 24, the slide member 14 is displaced in the longitudinal direction of the first rack 12.

[0090] At this time, since the operation lever 16 is operated in the second direction, the bar holding portion 23 rotates in the opposite direction to when the operation lever 16 is operated in the first direction. However, since the bar holding portion 23 rotates about the connecting portion 24, the first stopper 18 is displaced to one side in the longitudinal direction of the first rack 12 (the left side in FIG. 22).

[0091] Therefore, in the drawer mode, when the operator reciprocally swings the operation lever 16, the following operations occur: "the connecting portion 24 is displaced to one side in the longitudinal direction of the first rack 12" → "the first stopper 18 is displaced to one side in the longitudinal direction of the first rack 12" → "the connecting portion 24 is displaced to one side in the longitudinal direction of the first rack 12" → "the first stopper 18 is displaced to one side in the longitudinal direction of the first rack 12" → ······

[0092] That is, in the drawer mode, each time the operation lever 16 is operated in the first direction, the coupler 2 moves parallel in one direction in the longitudinal direction of the first rack 12, and each time the operation lever 16 is operated in the second direction, the first stopper 18 moves parallel in one direction in the longitudinal direction of the first rack 12. <3.2 When the coupler 2 is translated in the direction opposite to the arrow in FIG. 1> The operator sets the switching mechanism 22 to the pushing mode and then reciprocally swings the operation lever 16. As a result, the moving device 10 operates in the direction opposite to when it operates in the drawer mode.

[0093] Specifically, in the pushing-in mode, "the connecting portion 24 is displaced toward the other side in the longitudinal direction of the second rack 13" → "the second stopper 19 is displaced toward the other side in the longitudinal direction of the second rack 13" → "the connecting portion 24 is displaced toward the other side in the longitudinal direction of the second rack 13" → "the second stopper 19 is displaced toward the other side in the longitudinal direction of the second rack 13" → ······ and operates in this way.

[0094] That is, in the pushing-in mode, every time the operation lever 16 is operated in the second direction, the coupler 2 translates toward the other side in the longitudinal direction of the second rack 13, and every time the operation lever 16 is operated in the first direction, the second stopper 19 translates toward the other side in the longitudinal direction of the second rack 13.

[0095] And when the length of the operation lever 16 is sufficiently long, the rotational force for rotating the bar holding portion 23 becomes large. Therefore, according to the moving device 10 according to the present embodiment, it may be possible to perform the pulling-out and pushing-in operations of the coupler 2, for example, by one person. Consequently, it is possible to shorten the time required for the recovery work and to significantly reduce the work burden on the operator.

However, the present disclosure is not limited to this. That is, the present disclosure may be configured with, for example, only one of the racks provided. In this configuration, the switching mechanism 22 may be eliminated.

[0097] In each tooth portion 12A, 13A according to the above-described embodiment, the length of the first inclined surface h1 is longer than the length of the second inclined surface h2, and the angle θ formed by the second inclined surface h2 and the bottom surface bo is greater than 90 degrees.

That is, in the present disclosure, for example, it is sufficient that the first tooth stopper 18 and the second tooth stopper 19 have at least one protrusion.

[0101] The operation lever 16 according to the above-described embodiment was connected to the bar holding portion 23 at a position shifted toward the connecting portion 24 side with respect to the rotation center axis Lo. However, the present disclosure is not limited thereto. That is, in the present disclosure, for example, the operation lever 16 may be configured to be connected to the rotation center axis Lo, or the operation lever 16 may be configured to be connected coaxially with the connecting portion 24.

[0102] In the above-described embodiment, the first tooth stopper 18 was disposed on the opposite side of the second tooth stopper 19 with the rotation center axis Lo interposed therebetween. However, the present disclosure is not limited thereto. That is, in the present disclosure, for example, the first tooth stopper 18 and the second tooth stopper 19 may be configured to be disposed on the same side with respect to the rotation center axis Lo.
