  However, in the conventional wheel depressurizing apparatus, it is necessary to set the wheel shaft to be disassembled on a pair of support bases on a carriage using, for example, a crane. In this case, the disassembled object axle is first lifted by a crane and moved above the carriage (more specifically, the pair of support bases), and then moved to the pair of support bases so as not to give an impact or the like. You have to take it down slowly. At that time, in addition to the operator who operates the crane, an operator for adjusting the position of the disassembled wheel shaft to be moved by the crane and confirming the installation on the pair of support bases is also required. For this reason, it takes time and labor to set the wheel shaft to be disassembled on the carriage. The same applies to the axle after the wheels have been extracted. For example, the axle must be lowered from the carriage using a crane. In addition, crane operation requires some skill. In this respect, the conventional wheel depressurizing device has room for improvement, particularly in terms of work efficiency.

  Therefore, an object of the present invention is to provide a wheel shaft disassembly device that does not require crane operation and has excellent work efficiency.

In order to achieve the above object, a wheel shaft disassembly device according to one aspect of the present invention is a wheel shaft disassembly device that disassembles a wheel shaft into a wheel and an axle, is configured to be able to place the wheel shaft, and a wheel shaft to be disassembled is carried in.

The wheel lift device includes a wheel shaft discriminating device that detects the length of the wheel shaft to be disassembled and discriminates the type of the wheel shaft. Alternatively, the wheel extraction device is provided with a hydraulic press cylinder that axially presses an end portion of the axle of the disassembled wheel axle by advancement of the rod, and a periphery of the rod, A pair of clamp claws for clamping the wheel, and when the pair of clamp claws are in the first rotation position, the wheel of the wheel shaft to be disassembled is clamped, and the rod of the hydraulic press cylinder is advanced to perform the disassembly After removing the wheel from the disassembled object wheel wheel by pressing the axle of the object wheel wheel, and then rotating the pair of clamp claws in a state of clamping the removed wheel to the second rotation position and holding it for a predetermined time. It is comprised so that it may rotate to a 3rd rotation position.

  In the wheel shaft disassembly device, for example, the wheel shaft to be disassembled is rolled and moved to the wheel shaft carry-in position, the wheel shaft to be disassembled is lifted by the wheel shaft lift device, and the transport carriage is moved to the wheel shaft carry-in position. The wheel shaft to be disassembled is lowered onto the transport carriage by the wheel shaft lift device, so that the wheel shaft to be disassembled is placed on the transport cart.

Specifically, the wheel lift device 4 is disposed on one end side of the first linear rails 2, 2, and the axle moving device 6 is disposed on the other end side of the first linear rails 2, 2. A wheel extraction device 5 is arranged at an intermediate position in the extending direction 2. The transport carriage 3 can move between a position corresponding to the wheel lift device 4 on the first linear rails 2, 2, a position corresponding to the wheel extractor 5, and a position corresponding to the axle moving device 6. It is configured.

The transport carriage 3 is configured to be able to place the wheel shaft 10 to be disassembled.
As shown in FIG. 2, the transport carriage 3 includes a traveling carriage 31 that travels on a pair of first linear rails 2, 2, a rotating carriage 32 that can rotate horizontally on the traveling carriage 31, and a rotating carriage 32. A pair of axle support members 33, 33 provided, and a gear box support base 34 provided on the rotary carriage 32 are provided.

  FIG. 3 shows a schematic configuration of the traveling carriage 31. As shown in FIG. 3, the traveling carriage 31 is configured by a frame body 311 having a rectangular shape in plan view, and four wheels 312 that roll on the pair of first linear rails 2 and 2, and front and rear in the traveling direction, respectively. And a bumper switch 313 provided. In addition, a horizontal rotating plate 315 is attached to a substantially center of the frame body 311 via a support plate 314, and a rectangular plate-shaped rotating carriage 32 is installed on the horizontal rotating plate 315, thereby rotating. The carriage 32 can be rotated horizontally on the traveling carriage 31.

  In the traveling carriage 31, a plurality of support rollers 316 are arranged around the horizontal turntable 315 at a predetermined interval, and support rollers 316 are also arranged in the vicinity of the four corners. Has been. These support rollers 316 are mainly mounted on the frame body 311 or the support body 314, and support the lower surface of the rotating carriage 32 installed on the traveling carriage 31 (horizontal rotating disk 314) to support the rotating carriage. Assist horizontal rotation of 32. In particular, the rotating carriage 32 is prevented from being inclined when the rotating carriage 32 rotates horizontally on the traveling carriage 31.

  Further, the traveling carriage 31 is provided with a pair of lock pin receiving members 317 and 317. Each of the pair of lock pin receiving members 317 and 317 has an insertion hole 317a into which the lock pin is inserted when a lock pin (not shown) that is provided on the rotary carriage 32 and advances and retracts in the vertical direction has advanced. ing. One of the pair of lock pin receiving members 317 and 317 is provided at a position corresponding to the lock pin when the rotary carriage 32 is in a default position (that is, a position not horizontally rotated), and the other is It is provided at a position corresponding to the lock pin when the rotary carriage 32 is horizontally rotated by 180 °.

  When the rotary carriage 32 is at the default position or a position horizontally rotated 180 ° therefrom, the lock pin is advanced and inserted into the insertion hole 317a of the corresponding lock pin receiving member 317, so that the rotary carriage 31 Horizontal rotation is prevented, and at the same time, the rotary carriage 31 is firmly fixed at the default position and the position rotated 180 ° horizontally. Therefore, the lock pin receiving member 317 provided on the traveling carriage 31 and the lock pin provided on the rotary carriage 32 correspond to the “lock mechanism” of the present invention. Of course, when the rotary carriage 31 is rotated horizontally, the lock pin is retracted and is pulled out from the insertion hole 317a of the lock pin receiving member 317.

  The pair of axle support members 33, 33 are installed on the rotary carriage 32 and horizontally support the axle 12 of the wheel axle 10 to be disassembled on the transport carriage 3. Therefore, by rotating the rotating carriage 32 horizontally by 180 ° on the traveling carriage 31, the left and right sides of the wheel shaft 10 held by the pair of axle support members 33, 33 can be reversed.

FIG. 4 shows the axle support member 33.
As shown in FIG. 4, the axle support member 33 includes an arm support base 331, a pair of clamp arms 332 and 332 that are provided on the arm support base 331 and are movable in directions toward and away from each other, and an arm support base A height position adjusting mechanism 333 capable of adjusting the position of the pair of clamp arms 332 and 332 in the height direction by moving the 331 up and down.

  Each clamp arm 332 is provided with a pair of upper and lower gripping rollers 332 a, and the axle 12 of the wheel shaft 10 is gripped by the gripping rollers 332 a of both the clamp arms 332 and 332. The clamp arms 332 are moved by, for example, a hydraulic cylinder (not shown).

  The height position adjusting mechanism 333 includes a linear jack 334 configured by a combination of a worm gear and a ball screw, and a pair of linear guides 335 and 335 disposed with the linear jack 334 interposed therebetween. The linear jack 334 is driven by a servo motor (not shown) to raise and lower the arm support base 331, so that the arm support base 331 (a pair of arm support bases 331 is compared to the case where the arm support base 331 is lifted and lowered by a hydraulic cylinder or the like. The height positions of the clamp arms 332 and 332) can be accurately adjusted.

  Each linear guide 335 is composed of, for example, a combination of a slide bush and a guide rod, and prevents the arm support base 331 from being inclined when the arm support base 331 is raised or lowered by the linear jack 334.

  Returning to FIG. 2, the gear box support base 34 supports the gear box GB from below when the wheel shaft 10 to be disassembled is a wheel shaft (M shaft) of an electric vehicle (M vehicle) equipped with a motor. The support base 34 is configured to be movable up and down by a hydraulic cylinder (not shown), for example. Since the gear box GB is heavy, when the wheel shaft 10 to be disassembled is the axle (M axis) of an electric vehicle (M car), the load applied to the pair of axle support members 33 and 33 is biased. There is a possibility that the axle 12 cannot be horizontally supported with high accuracy. In particular, as will be described later, when one wheel 12 is pulled out, the load applied to the pair of axle support members 33, 33 becomes large, and therefore the axle 12 may be inclined only by the pair of axle support members 33, 33. There is. Of course, it is possible to configure the pair of axle support members 33 and 33 so as to be able to withstand such a large deviation as described above, but in this case, a significant cost increase is involved. Therefore, by supporting the gear box GB from below by the gear box support base 34, the inclination of the axle 12 caused by the bias of the load applied to the pair of axle support members 33, 33 is suppressed.

  Next, the wheel lift device 4 is a stationary device that lifts the disassembled wheel shaft 10 placed on the floor and places the wheel shaft 10 on the transport carriage 3. As shown in FIG. Various controls including a pair of wheel lifters 41, 41 provided with one straight rail 2, 2, a determination sensor 42 for determining the type of the wheel shaft 10 to be disassembled, and an operation control of the pair of wheel lifters 41, 41. And a control device 43 that executes

  The pair of wheel shaft lifters 41 and 41 are, for example, hydraulic lifters. As shown in FIG. 5, a holding arm 411 that holds the end of the wheel shaft 10 (axle 12) and a hydraulic cylinder that moves the holding arm 411 up and down. 412 and lifts up the wheel shaft 10 while holding both ends of the wheel shaft 10 to be disassembled.

  The discrimination sensor 42 is a type of the wheel shaft 10 to be disassembled, for example, a wheel shaft (M shaft) of an electric vehicle (M vehicle) equipped with a motor or a wheel shaft (T shaft) of an accompanying vehicle (T vehicle) not equipped with a motor. ). The discrimination sensor 42 is not particularly limited as long as it can discriminate the type of the wheel shaft, but in this embodiment, an air cylinder with a rod position detector is used. The air cylinder is configured such that the rod can be advanced and retracted in the horizontal direction, and is mounted in the holding arm 411 of the wheel lifter 41. Then, the air cylinder advances the rod, detects the rod position when the rod comes into contact with the end of the wheel shaft 10 to be disassembled, and outputs the detected rod position to the control device 43.

The control device 43 includes an input unit through which various information is input by an operator, a storage unit that stores various types of information related to disassembly of the wheel shaft 10, and a display unit that displays various types of information (none of which are shown).
The control device 43 controls the operation of the pair of wheel lifters 41 and 41 and the air cylinder as the discrimination sensor 42 based on an operation command from the operator via the input unit. Further, the control device 43 inputs the rod position from an air cylinder mounted in the holding arm 411 of each of the pair of wheel shaft lifters 41, 41, and the length of the wheel shaft 10 to be disassembled based on the input rod position. And the type of the wheel shaft 10 is determined based on the detection result.

  In the present embodiment, when the wheel lift device 4 is operated, the operator first inputs the type of the wheel shaft 10 to be disassembled recognized by the operator via the input unit, and then inputs the type via the input unit. The operation command is input. Then, the control device 43 compares the input type of the wheel shaft 10 with the determined type of the wheel shaft 10, and allows the lift-up operation of the wheel shaft 10 by the pair of wheel shaft lifters 41, 41 only when they match. Is configured to do. Thereby, the malfunction of the pair of wheel lifters 41, 41 due to an operator's setting error or the like is prevented, and the safety of work is ensured.

  Further, when the input type of the wheel shaft 10 and the determined type of the wheel shaft 10 are different, the control device 43 displays an error on the display unit, for example, to alert the operator, and When the type of the wheel shaft 10 that has been determined and the type of the wheel shaft 10 that has been determined are the same, information corresponding to the type of the wheel shaft 10 (for example, various set values in the transport carriage 3) is displayed on the display unit. .

  Here, although omitted in the figure, the wheel shaft lift device 4 may include a gear box lifter in addition to the pair of wheel shaft lifters 41, 41. This gear box lifter moves up and down while being engaged with or fixed to the gear box when the wheel shaft 10 to be disassembled is a wheel shaft of an electric vehicle (M vehicle), and thereby the wheel shaft by the pair of wheel shaft lifters 41 and 41. It assists 10 lift-ups. The gear box lifter is constituted by, for example, a hydraulic cylinder, and is installed on a ceiling above the pair of first linear rails 2 and 2. Thus, by providing the gear box lifter separately from the pair of wheel lifters 41, 41, the wheel lifters 41, 41 can be reduced in size, and the gear box lifter can be operated only when necessary. Therefore, it contributes to power saving as the entire wheel lift device 4.

  In the configuration provided with the gear box lifter, when the type of the input wheel shaft 10 and the determined type of the wheel shaft 10 are different, the control device 43 displays an error on the display unit and also displays a gear. It is preferable to display that the box lifter is activated. Further, the pair of wheel lifters 41 and 41 corresponds to the “main lifter” of the present invention, and the gear box lifter corresponds to the “auxiliary lifter” of the present invention.

  Next, the wheel extractor 5 is an apparatus for extracting the wheel 11 from the wheel shaft 10 to be disassembled placed on the transport carriage 3, and as shown in FIGS. 1 and 6, a hydraulic press cylinder 51 and a pair of clamp claws 52. , 52 and a control device 53.

  The hydraulic press cylinder 51 is configured to be movable in a direction (indicated by an arrow A in FIGS. 1 and 6) orthogonal to the extending direction of the pair of first linear rails 2 and 2 and on the front side thereof (the first linear rail 2 , 2 side) is provided with a rod 51a that advances and retreats by hydraulic pressure. A rotary disc 54 that can rotate around a rod 51 a is provided on the front surface of the hydraulic press cylinder 51, and a pair of clamp claws 52, 52 are attached to the rotary disc 54 so as to be openable and closable. The control device 53 controls the operation of the hydraulic press cylinder 51, the pair of clamp claws 52 and 52, and the turntable 54 based on a command from an operator via an input unit (not shown).

  Then, under the control of the control device 53, the wheel extraction device 5 clamps the wheel 11 of the wheel shaft 10 placed on the transport carriage 3 with a pair of clamp claws 52, 52, and the rod 51a of the hydraulic press cylinder 51 is clamped. Advance and push the axle 12. The floor in front of the wheel extraction device 5 is formed as a partially divided moving floor portion, and the moving floor portion and the pair of first linear rails 2 and 2 installed on the moving floor portion are arranged. The corresponding portion is configured to be movable in a direction orthogonal to the extending direction of the pair of first linear rails 2, 2, more specifically, in a direction away from the hydraulic press cylinder 51. When the axle 12 is pressed by the rod 51a of the hydraulic press cylinder 51 in a state where the wheel 11 is clamped by the pair of clamp claws 52, 52, the transport carriage 3 moves in a direction away from the hydraulic press cylinder 51 together with the moving floor portion. Thereby, the wheel 12 is extracted.

  Here, as shown in FIG. 1, in this embodiment, a second straight line extending parallel to the first straight rails 2, 2 is provided between the hydraulic press cylinder 51 and the pair of first straight rails 2, 2. Rails 22 are provided. A carriage 23 for carrying out the wheels travels on the second linear rails 22 and 22. The wheel carrying cart 23 is provided with a wheel holding portion 24 capable of standing and lying on the upper surface thereof, and receives the wheel 11 extracted by the wheel extraction device 5 by the wheel holding portion 24 in the standing state. And move on the second straight rails 22 and 22 in a direction away from the wheel extractor 5. Then, the wheel 11 can be mounted on the wheel transfer conveyor 25 by moving the wheel holding part 24 in the direction orthogonal to the moving direction of the wheel carriage 23 and further falling down. Thereby, the wheel 11 extracted by the wheel extraction device 5 is conveyed to the wheel collection position by the wheel transfer conveyor 25 in a predetermined manner.

  Next, the axle movement device 6 moves the axle 12 placed on the transport carriage 3, that is, the axle 12 after the wheels 11 are extracted, from the transport carriage 3 to another place, for example, a predetermined position on the floor. 1 and includes a pair of axle lifters 61 and 61 and a control device 62, as shown in FIG.

  The pair of axle lifters 61, 61 are, for example, hydraulic lifters, like the pair of wheel lifters 41, 41, and as shown in FIG. 1, a holding arm 611 and a holding arm 611 for holding the end of the axle 12, respectively. And a hydraulic cylinder (not shown). The pair of axle lifters 61 and 61 are configured to be movable in parallel with the extending direction of the first linear rails 2 and 2 as indicated by an arrow B in FIG. The control device 62 controls the operation of the pair of axle lifters 61 and 61 based on an operation command by an operator via an input unit (not shown).

  The axle moving device 6 holds both ends of the axle 12 mounted on the transport carriage 3 with a pair of holding arms 611 and 611 under the control of the control device 62, and in this state, the pair of holding arms 611 and 611 The axle 12 is lifted up by raising 611. Thereafter, the pair of axle lifters 61, 61 are moved to positions corresponding to the axle transport pallet 26, the pair of holding arms 611, 611 are lowered, and the axle 12 is placed on the axle transport pallet 26. The axle conveyance pallet 26 is installed on, for example, an axle transfer conveyor (not shown), and thereby the axle 12 is conveyed to a predetermined axle collection position.

Next, the operation of the wheel shaft disassembly device 1 having the above configuration will be described.
First, for example, the operator carries the wheel shaft 10 to be disassembled to the wheel lift device 4 by rolling on the floor. Next, the operator operates the wheel shaft lift device 4 to lift the wheel shaft 10 to be disassembled, and moves the transport carriage 3 to a position corresponding to the wheel shaft lift device 4 on the first linear rails 2 and 2. Thereafter, the operator operates the wheel lift device 4 to lower the wheel shaft 10 to be disassembled, and horizontally supports the axle 12 of the wheel shaft 10 by the pair of axle support members 33, 33 on the transport carriage 3. Thereby, the wheel shaft 10 to be disassembled is placed on the transport carriage 3. Therefore, in the present embodiment, the position corresponding to the wheel lift device 4, that is, the one end side of the pair of first linear rails 2, 2 corresponds to the “wheel shaft loading position where the wheel shaft to be disassembled is loaded”.

  Next, the operator moves the transport carriage 3 on which the wheel shaft 10 to be disassembled is placed to a position corresponding to the wheel extractor 5 and operates the wheel extractor 5 to move the wheels 12 from the wheel shaft 10 to be disassembled. Extract (separate). Therefore, in the present embodiment, the position corresponding to the wheel extraction device 5, that is, the intermediate position in the extending direction of the pair of first linear rails 2 and 2, is “wheel separation for separating the wheel from the disassembled axle. Corresponds to “position”.

Here, the operation of the wheel extraction device 5 will be described.
In the present embodiment, when the pair of clamp claws 52, 52 are arranged vertically with the rod 51a interposed therebetween and are in the open state, the initial state of the wheel extraction device 5 is set. When the wheel extractor 5 is in the initial state, the transport carriage 3 on which the wheel shaft 10 to be disassembled is placed is moved from the wheel lift device 4 to the wheel extractor 5.

  When the transport carriage 3 moves to the wheel extraction device 5, the operator operates the wheel extraction device 5. As a result, the wheel extraction device 5 closes the pair of clamp claws 52, 52 to clamp one wheel 11 of the wheel shaft 10 on the transport carriage 3, and advances the rod 51a of the hydraulic press cylinder 51 to press the wheel shaft 12. As a result, the one wheel 11 is extracted from the wheel shaft 10. Thereafter, the wheel extractor 5 retracts (returns) the rod 51a that the hydraulic press cylinder 51 has advanced. At this time, the extracted wheel 11 remains clamped by the pair of clamp claws 52 and 52.

  Here, when the axle 12 is pressed by the rod 51 a of the hydraulic press cylinder 51, leaked oil or the like accompanying the pressure increase adheres to the wheel 11 and the axle 12. Therefore, the wheel extractor 5 removes the oil adhering to the wheel 11 by removing the wheel 11 and then rotating the turntable 54 (the pair of clamp claws 52, 52), for example, by rotating it 90 degrees and returning it again. Yes (oil removal treatment). However, the wheel extractor 5 does not rotate the rotating plate 54 (the pair of clamp claws 52, 52) by 90 ° at a time, but temporarily stops the wheel at a predetermined angle (for example, 45 °) in the middle thereof. The oil adhering to 11 is effectively removed.

  That is, the wheel extraction device 5 clamps the wheel 11 when the pair of clamp claws 52, 52 are in the first rotation position, extracts the wheel 11, and then moves the pair of clamp claws 52, 52 to the second rotation position. (For example, rotated by 45 °) and held for a predetermined time, and then rotated to the third rotational position (for example, further rotated by 45 °). Thereby, the oil adhering to the extracted wheel 11 can be effectively dropped, and the dropped oil can be recovered by, for example, an oil pan (not shown) arranged below the wheel 11.

  Thereafter, the wheel extraction device 5 rotates the pair of clamp claws 52, 52 by 90 ° so that the pair of clamp claws 52, 52 are arranged on the left and right with the rod 51a interposed therebetween. At this time, the wheel carry-out carriage 23 moves to a position corresponding to the wheel extraction device 5, and the wheels 11 clamped by the pair of clamp claws 52, 52 are delivered to the wheel carry-out carriage 23. That is, the pair of clamp claws 52, 52 are opened so that the wheel 11 is placed on the wheel carrying carriage 23 and the wheel 11 is held by the wheel holding unit 24. Thereafter, as described above, the wheel carrying carriage 23 is moved to place the wheel 11 on the wheel transfer conveyor 25. Thereby, one wheel 11 is extracted from the wheel shaft 10 to be disassembled placed on the transport carriage 3.

  Next, the operator moves the hydraulic press cylinder 51 in a direction away from the first linear rails 2 and 2 (see arrow A), and the axle 12 is pressed by the rod 51a of the hydraulic press cylinder 51, thereby moving the moving bed. The rotary carriage 32 of the transport carriage 3 moved in the direction orthogonal to the extending direction of the first linear rails 2 and 2 together with the section is horizontally rotated by 180 ° (see the circle shown by the two-dot chain line in FIG. 1). Thereafter, the hydraulic press cylinder 51 and the moving floor part are returned to their original positions, and the wheel extraction device 5 is operated in the same manner as described above, whereby the other wheel 11 of the wheel shaft 10 on the transport carriage 3 is extracted. Thereby, the extraction process (wheel separation process) of the wheel 11 from the wheel shaft 10 to be disassembled placed on the transport carriage 3 is completed.

  When the wheel separation process ends, the operator moves the transport carriage 3 to a position corresponding to the axle movement device 6, operates the axle movement device 6, and moves the axle 11 placed on the conveyance carriage 3 to the transport carriage 3. To the axle transport pallet 26. In other words, the axle moving device 6 lifts up the axle 12 placed on the transport carriage 3 by the pair of axle lifters 61, 61, and then moves the pair of axle lifters 61, 61 to move the lifted axle 12 up. It is lowered and placed on the axle transport pallet 26. Therefore, in the present embodiment, the position corresponding to the axle movement device 6, that is, the other end side of the pair of first linear rails 2, 2 is “the axle carry-out position for carrying out the axle after the wheels are separated. Is equivalent to.

  Then, by moving the axle 12 mounted on the transport carriage 3 to the axle transport pallet 26 by the axle moving device 6, the process of separating the axle 10 to be disassembled into the wheel 11 and the axle 12 is completed.

  As described above, according to the wheel shaft disassembling apparatus 1 according to the present embodiment, when the wheel shaft 10 is separated into the wheel 11 and the axle 12, no crane operation is required. It is possible to reduce manpower and manpower, and work efficiency can be improved.

  Here, the wheel lift device 4 for placing the wheel shaft 10 to be disassembled on the floor on the transport carriage 3 includes a gear box lifter (auxiliary lifter) in addition to the pair of wheel shaft lifters 41 and 41 (main lifter). Thus, the wheel shaft lifters 41 and 41 can be reduced in size, and the wheel shaft (M shaft) of the heavy electric vehicle (M vehicle) can be lifted up and placed on the transport carriage 3 with certainty. Further, since the gear box lifter only needs to be operated when necessary, that is, when the wheel shaft to be disassembled is the wheel shaft (M axis) of the electric vehicle (M vehicle), power saving of the wheel shaft lift device 4 can be achieved. Also contributes.

  Further, since the wheel lift device 4 includes a determination sensor 42 that determines the type of the wheel shaft 10 to be disassembled, for example, the operation amount of the wheel lifters 41 and 41 and the press cylinder 51 according to the type of the wheel shaft 10 to be disassembled. It is possible to automatically change the operation amount (stroke position) of the rod 51a. Thereby, lift-up of the wheel shaft 10 to be disassembled and extraction of the wheel 11 from the wheel shaft 10 to be disassembled (that is, pressing of the axle 12 by the rod 51a of the hydraulic press cylinder 51) can be performed stably and reliably.

  Further, when the type of the wheel shaft 10 to be disassembled input by the operator matches the type of the wheel shaft 10 to be disassembled determined by the determination sensor 42, the wheel shaft lift device 4 matches the wheel shaft 10 formed by the wheel shaft lifters 41 and 41. Therefore, the malfunction of the wheel lifters 41 and 41 can be reliably prevented, and the work safety can be ensured.

  Further, the transporting carriage 3 includes a traveling carriage 31 that travels on the first linear rails 2, 2, a rotating carriage 32 that can rotate horizontally on the traveling carriage 31, and a pair of axle supports provided on the rotating carriage 32. Each of the pair of axle support members 33, 33 is configured such that its height position can be independently adjusted. As a result, the axle 12 of the wheel shaft 10 to be disassembled can always be supported horizontally, and both of the wheel shafts 10 to be disassembled by the wheel extractor 5 disposed only on one side of the first linear rails 2 and 2. The wheel 11 can be extracted. Here, the lower surface of the rotary carriage 32 is supported by a plurality of support rollers 316. In particular, the tilt of the rotary carriage 32 during horizontal rotation after the one wheel 11 is extracted is suppressed, and the rotation carriage 32 is stabilized. Horizontal rotation can be realized.

  Furthermore, the transport carriage 3 includes a gear box support base 34 that supports the gear box GB of the wheel shaft 10 from below when the wheel shaft 10 to be disassembled is a wheel shaft (M shaft) of an electric vehicle (M car). Therefore, it is possible to effectively prevent the axle 12 from being inclined particularly when one of the wheels 11 is pulled out, and while reducing the burden on the pair of axle support members 33, 33, the pair of axle support members 33, 33. As a result, stable horizontal support of the axle 12 is ensured.

  Further, the rotary carriage 32 is prevented from rotating horizontally and firmly by inserting the lock pin into the insertion hole 317a of the lock pin receiving member 317 on the traveling carriage 31 side at the default position and the position horizontally rotated by 180 °. Since it is fixed, especially the extraction process of the wheel 11 by the wheel extraction device 5 can be stably performed.

  Furthermore, the wheel extraction device 5 rotates the pair of clamp claws 52 and 52 from the first rotation position to the second rotation position after extracting the wheel 11 and holds it for a predetermined time, and then rotates it to the third rotation position. Therefore, the oil attached to the wheel 11 when the wheel 11 is extracted can be effectively removed, and the removed oil can be recovered.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention. is there.
