The present invention will be described below with reference to the illustrated embodiments. In FIGS. 1 to 3, reference numeral 1 denotes a wheel shaft cleaning device for cleaning the wheel shaft 2 of a railway vehicle. Cleaning is performed in a state where the wheel shaft 2 is supported at a cleaning height that is above the surface F.
Before describing the configuration of the wheel shaft cleaning device 1, the configuration of the wheel shaft 2 to be cleaned will be described. As shown in FIGS. 2 to 3, the wheel shaft 2 of the railway vehicle is composed of a round bar-shaped axle 2A and a pair of wheels 2B and 2B fitted to the outer peripheral portions near both ends of the axle 2A. A gear box 4 is attached to the inner side of one of the wheels 2B.
The outer peripheral portions of both ends of the axle 2A are bearing seats 2Aa, and both of these bearing seats 2Aa are rotatably supported by a bearing of a vehicle body (not shown).
The gear box 4 is interlocked with a drive source on the vehicle body side. When the drive source is driven in a state where the gear box 4 is interlocked with the drive source, the axle 2A is connected via the gear in the gear box 4. And the wheel 2B are rotated together, so that the wheel shaft 2 rolls on the rail.
A flange portion 2Ba is formed at the inner edge of the wheel 2B, and the outer peripheral surface of the wheel 2B adjacent to the flange portion 2Ba is a tread surface 2Bb in contact with the railroad rail.

  The wheel-shaft cleaning apparatus 1 of the present embodiment includes a cleaning machine body 3 that cleans the wheel shaft 2 at a cleaning height that is higher than the floor surface F at the cleaning position A, and a cleaning at a loading position B that is upstream of the cleaning machine body 3. A carrying-in means 7 for bringing the target wheel shaft 2 from the floor F to a predetermined height and then carrying it into the washing position A, and the wheel shaft 2 washed by the washing machine body 3 at the unloading position C on the downstream side of the washing machine body 3. Is carried out by lowering to the height of the floor F.

The carry-in means 7 includes a fixed frame 11 provided on the floor F at the carry-in position B, a lift frame 12 provided on the fixed frame 11 so as to be lifted and lowered, a lift mechanism 13 for lifting and lowering the lift frame 12, and a lift mechanism. 13 is supported by rails 14A and 14A provided on the movable support member 14 and a movable support member 14 that can swing between a support position for supporting the wheel shaft 2 that has been lifted by 13 and a retracted position that deviates from the support position. An extrusion mechanism 15 that pushes the wheel shaft 2 toward the cleaning position A is provided.
The fixed frame 11 is provided with a total of four columns 16, and the lifting frame 12 is disposed over each of the two columns 16 on the left and right sides of the fixed frame 11 so as to be lifted and lowered along the two columns 16. It has become.
Lower ends of the chains 17 and 17 are connected to upper portions on both the left and right sides of the lifting frame 12, and the lifting frame 12 is horizontally supported by the left and right chains 17 and 17. The lifting frame 12 is lifted and lowered via a left and right chain 17, 17 over a lower end position indicated by a solid line on the lower side in FIG. 1 and a rising position above the cleaning height.
On the inner surfaces of both sides of the lifting frame 12, support portions 12 </ b> A and 12 </ b> A made of V-shaped grooves project from each other. When the wheel shaft 2 is loaded into the loading position B manually or automatically by an operator, the wheel shaft 2 may be lifted by supporting the bearing seat 2Aa of the wheel shaft 2 from the lower side with a pair of left and right support portions 12A and 12A. It can be done.

A pair of rails 18, 18 extending toward the cleaning position A is provided across the floor F at the carry-in position B and the floor F on the adjacent upstream side thereof. Instead of laying the rails 18, existing grooves formed in the floor F of the vehicle base can be used. The wheel shaft 2 to be cleaned is removed from the vehicle body and is manually or automatically moved to a position adjacent to the loading position B by a worker on site and moved to the loading position B.
At this time, since the lifting frame 12 is positioned in the lower end position in advance, both support portions 12A of the lifting frame 12 are positioned on the lower side adjacent to the bearing seat 2Aa of the wheel shaft 2. When the lift frame 12 is lifted by a required amount via the chains 17 and 17 of the lift mechanism 13 from this state, the wheel shaft 2 is moved along with the lift of the lift frame 12 after the left and right bearing seats 2Aa are supported by the two support portions 12A. Is raised slightly above the cleaning height.
Since the gear box 4 is attached to the wheel shaft 2, when the wheel shaft 2 is supported and lifted by the lifting frame 12, the gear box 4 rotates carelessly and falls in a posture or falls and crashes. It is necessary to prevent this. For this purpose, in this embodiment, a fixing means 12B for fixing the gear box 4 so as not to rotate is provided at the upper center of the elevating frame 12. The fixing means 12B includes a chain having an upper end connected to the lifting frame 12 and a hook attached to the lower end of the chain. When the wheelset 2 is carried into the carrying-in position B, the hook of the fixing means 12B is geared by an operator. The main part of the box 4 is hooked. As a result, when the bearing seat 2Aa of the wheel shaft 2 is supported and lifted by the two support portions 12A and 12A, the gear box 4 is prevented from rotating carelessly with respect to the axle 2A.
The configuration of the fixing means 12B is not limited to this as long as the gear box 4 is fixed to prevent inadvertent rotation.

A rotating shaft 21 is rotatably supported in a horizontal state on the upper portion of the fixed frame 11, and sprockets 22 and 22 fitted to both ends of the rotating shaft 21 are engaged with the left and right chains 17. The rotating shaft 21 is rotated forward and backward in conjunction with the motor 23. The operation of the motor 23 is controlled by a control device (not shown). When the motor 23 is rotated forward as required by the control device, the elevating frame 12 is raised via the rotary shaft 21, sprocket 22 and chain 17. On the other hand, when the motor 23 is reversely rotated by the control device, the elevating frame 12 is lowered via the rotary shaft 21, the sprocket 22 and the chain 17. The elevating mechanism 13 that elevates the elevating frame 12 includes a chain 17, a sprocket 22, a rotating shaft 21, and a motor 23.
In the present embodiment, the lifting frame 12 is stopped at the lower end position of the loading position B before the wheel shaft 2 is loaded into the loading position B. In this state, the support portion 12A of the elevating frame 12 is positioned below the bearing seat 2Aa of the wheel shaft 2 to be carried.
Thereafter, when the wheel shaft 2 is carried into the carry-in position B manually or automatically by the operator, the motor 23 is rotated forward by the control device. Thereby, the bearing seat 2Aa of the wheel shaft 2 is supported by the support portions 12A and 12A as the lifting frame 12 is raised by a required amount, and is raised to a position slightly higher than the cleaning height.

In order to roll the wheel shaft 2 raised from the carry-in position B to the wash position A on the washing machine main body 3 side, the intermediate deck 24 is horizontally placed at a predetermined height between the wash position A and the carry-in position B. Is provided. A pair of left and right rails 25 are horizontally provided on the intermediate deck 24 from the carry-in position B to the cleaning position A. The height of the rail 25 of the intermediate deck 24 is the same as the cleaning height at the cleaning position A.
The movable support member 14 is swingably attached to the upstream end of the frame of the intermediate deck 24 via a hinge. A pair of rails 14 </ b> A and 14 </ b> A are provided on the left and right edges of the movable support member 14. These rails 14A and 14A are positioned in a straight line at the same height (washing height) as the rails 25 of the intermediate deck 24 when the movable support member 14 is raised to a substantially horizontal state and becomes a support position. (See FIG. 1).
The front end of the piston 26A of the air cylinder 26 is connected to the center of the back surface of the movable support member 14, and the operation of the air cylinder 26 is controlled by a control device.
In a non-operating state of the air cylinder 26, the movable support member 14 is located in a substantially vertical state at a retracted position that is out of the support position and does not support the wheel shaft 2. On the other hand, when the air cylinder 26 is actuated by the control device, the movable support member 14 is swung from the retracted position to the support position that is in a substantially horizontal state by the piston 26A being advanced to the forward end (see FIG. 1, the state of FIG.
In the present embodiment, the control device operates the air cylinder 26 after the wheelchair 2 is supported by the elevating frame 12 and the required amount is raised. Thus, the movable support member 14 is horizontally supported at a predetermined height at the carry-in position B, and at that time, the wheel 2B (tread surface 2Bb) of the wheel shaft 2 is positioned on the upper side of the movable support member 14 adjacent to the rails 14A, 14A. It has become.
In this state, when the lift frame 12 is lowered by a required amount via the motor 23 of the lift mechanism 13, the lower end of the wheel 2B (the tread surface 2Bb) of the wheel shaft 2 is supported on the rails 14A and 14A of the movable support member 14. (See FIG. 2). At this time, the two support portions 12A and 12A of the elevating frame 12 are separated from the bearing seat 2Aa of the wheel shaft 2 and are positioned on the lower side thereof. That is, the wheel shaft 2 is supported at the same height as the cleaning height by the rails 14A and 14A of the movable support member 14.

In this embodiment, when the wheel shaft 2 is supported by the movable support member 14 as described above, the movable support member 14 is supported by the pair of stoppers 27 and 27 from the lower side. These stoppers 27, 27 are arranged upward toward the adjacent outer position of the rails 18, 18 at the loading position B, and the lower ends of the stoppers 27, 27 are connected to the air cylinders 28, 28. .
The operation of the air cylinders 28 and 28 is controlled by a control device, and when the air cylinders 28 and 28 are not operated, the stoppers 27 and 27 are stopped at a separated position where they do not contact the movable support member 14. Yes. On the other hand, when the movable support member 14 is swung slightly above the position where it is substantially horizontal, both air cylinders 28 and 28 are actuated by the control device so that the stoppers 27 and 27 are close to each other by a required angle. Swing. Therefore, the support recesses 28A that are the upper ends of the stoppers 27 and 27 are located below both side portions (rails 14a) of the movable support member 14, and thereafter, the air cylinder 26 is operated by the control device so that the movable support member 14 is moved. The support recess 28A and the movable support member 14 are engaged when the substantially horizontal state is reached. Accordingly, the movable support member 14 is maintained in a horizontal state, and the movable support member 14 and the wheel shaft 2 placed thereon can be supported (see FIG. 2).
When the operator removes the hook of the fixing means 12B from the gear box 4 in a state where the movable support member 14 is in a substantially horizontal state and supports the wheel shaft 2 in this way, the wheel shaft 2 is moved to the rail 14A of the movable support member 14. Can be rolled toward the cleaning position A.
In this embodiment, the wheel shaft 2 is pushed out by the pushing mechanism 15 in this state, and can be carried along the rails 14A and 25 to the cleaning position A.

That is, as shown in FIGS. 1 and 2, the rotary shaft 31 is rotatably supported on the back of the upper end of the fixed frame 11, and the upper ends of the pair of left and right push arms 32 are supported at both ends of the rotary shaft 31. Are connected. The two push-out arms 32 are connected to the rotary shaft 31 so as to face each other, and the retraction position adjacent to the loading position B via the rotary shaft 31 and the push-out position moved by a required amount from there to the cleaning position. And can be swung. The rotating shaft 31 is rotated by a motor 33, and the operation of the motor 33 is controlled by a control device.
When the wheel shaft 2 is supported by the rail 14A of the movable support member 14 that has become substantially horizontal at the support position, and then the fixed state of the gear box 4 by the fixing means 12B is released by the operator, the pushing mechanism 15 is controlled by the control device. The motor 33 is activated.
Therefore, both the pushing arms 32, 32 are swung from the retracted position toward the pushing position, and the wheel 2B of the wheel shaft 2 is directed toward the washing position A via a roller provided at the lower end portion of the pushing arms 32. Extruded. Accordingly, the wheel shaft 2 is carried onto the rail 35 at the cleaning position A along the rail 14 </ b> A of the movable support member 14 and the rail 25 of the intermediate deck 24.
As described above, the wheel shaft 2 is carried from the carry-in position B to the cleaning position A by the carry-in means 7, and thereafter, the push-out arm 32 of the push-out mechanism 15 returns to the original retracted position and is movable. The support member 14 also returns from the substantially horizontal state to the substantially vertical state. Further, since the motor 23 of the elevating mechanism 13 is reversed thereafter, the elevating frame 12 is lowered from the raised position to the lowered end position and stopped.

Next, the cleaning machine main body 3 disposed at the cleaning position A will be described. As shown in FIGS. 1 and 3, the cleaning machine main body 3 supports the wheel shaft 2 at a predetermined cleaning height at the center of the cleaning position A. The left and right support rollers 36A and 36B that support the rails 35 and 35, and the flange portion 2Ba of the wheel 2B in the wheel shaft 2, and the wheels 2B and the axle 2A around the shaft through these support rollers 36A and 36B at the time of cleaning. And a cleaning mechanism 38 for cleaning the wheel shaft 2 by spraying the cleaning liquid W.
The entire region of the cleaning machine body 3 is covered with a box-shaped casing 41, the inside of the casing 41 is a cleaning chamber 42, and the cleaning chamber 42 is a cleaning position A. A carry-in port 41A is opened on the wall surface on the carry-in position B side in the casing 41, and this carry-in port 41A can be opened and closed by an entrance-side shutter 43A. Further, a carry-out port 41B is opened on the wall surface on the carry-out position C side of the casing 41, and the carry-out port 41B can be opened and closed by an exit-side shutter 43B.
When the wheel shaft 2 is carried into the cleaning chamber 42 by the carrying-in means 7, the shutter 43A is opened, and when the wheel shaft 2 is carried into the cleaning chamber 42, the shutter 43A is closed. ing. In this state, the cleaning liquid W is jetted toward the wheel shaft 2 by the cleaning mechanism 38. After the cleaning operation, the shutter 43B is opened when the cleaned wheel shaft 2 is sent out from the cleaning chamber 42 toward the carry-out position C.

The rails 35, 35 arranged in the cleaning chamber 42 are arranged at the same height on the extension of the rail 25 of the intermediate deck 24. Therefore, when the wheel shaft 2 at the loading position B is pushed out toward the cleaning position A by the push-out mechanism 15 as described above, after rolling toward the cleaning chamber 42 via the rail 25 of the intermediate deck 24, the cleaning chamber It stops and waits by a stopper (not shown) just before 42. When the shutter 43A is opened, the wheel shaft 2 is carried into the central portion of the rail 35 of the cleaning chamber 42 manually or automatically by the operator.
A central portion 35A of the left and right rails 35 is formed in a substantially V-shaped recess, and the central portion 35A is formed at a normal horizontal position and an inclined position where a portion on the loading position B side is pushed up obliquely upward. It is movable. As will be described in detail later, the wheel shaft 2 can be sent out toward the carry-out position C by pushing up the central portion 35A obliquely upward by the delivery mechanism 45 after the washing of the wheel shaft 2 is completed.
The support roller 36A on the carry-out position C side of the support rollers 36A and 36B is a free roller that freely rotates, and the other support roller 36B is a drive roller that is rotated in conjunction with the motor 46 of the rotation mechanism 37. ing. The support rollers 36 </ b> A and 36 </ b> B are arranged at predetermined positions in the longitudinal direction at positions adjacent to the rail 35. Therefore, when the wheel shaft 2 rolls on the rails 35 and 35 from the loading position B to the cleaning position A, the lower end portion of the flange portion 2Ba of the wheel shaft 2 is located between the two left and right support rollers 36A and 36B. The lower end portion of the tread surface 2Bb of the wheel 2B is placed on the V-shaped central portion 35A of the rails 35 while being supported. Thereby, the wheel shaft 2 is stopped at the center of the cleaning position A.

A rotation mechanism 37 is disposed at a cleaning position A below the rails 35, 35, and a recovery groove 41C for collecting and recovering the cleaning liquid after cleaning is provided at the center of the floor in the casing 41. Yes.
Rotating shafts 48 and 48 are rotatably supported on the adjacent lower side of the rails 35 and 35, and the supporting roller 36B as a driving roller is fitted to each rotating shaft 48. A rotating shaft 49 is rotatably supported at the lower central portion of the cleaning chamber 42, and is fitted to the gears 51, 51 fitted to both ends of the rotating shaft 49 and the rotating shafts 48, 48. Timing belts 53, 53 are stretched over the gears 52, 52.
Further, a gear 54 is fitted to one end of the rotating shaft 49, and a timing belt 56 is stretched over the gear 54 and the gear 55 on the motor 46 side. The operation of the motor 46 is controlled by a control device.
In the cleaning operation in which the cleaning liquid W is sprayed from the spray nozzles 57 and 58 of the cleaning mechanism 38 toward the wheel shaft 2 carried into the cleaning position A, the control device rotates the motor 46 for a required time. For this reason, the left and right support rollers 36B and 36B are rotated synchronously via the timing belts 56 and 53, both rotating shafts 48, and the like, so that the wheel shaft 2 supported by them is rotated around the axis. As a result, the cleaning liquid W sprayed from the spray nozzles 57 and 58 is sprayed to the entire outer surface of the wheel shaft 2.

On the upper side of the wheel shaft 2 stopped at the center of the cleaning position A, an injection nozzle 57 for injecting the cleaning liquid W toward the lower wheel shaft 2 is arranged vertically downward. An injection nozzle 58 that injects the cleaning liquid W in the horizontal direction toward the wheel 2B is also disposed at a position adjacent to 2B.
The injection nozzle 58 is fixedly arranged, but the upper injection nozzle 57 is reciprocated in a direction orthogonal to the rails 35, 35 by the reciprocating mechanism 60.
Above the casing 41, a pair of upper and lower guide rails 61, 61 are provided in a direction orthogonal to the rails 35, 35, and a support member 62 is provided across the both guide rails 61, 61. The support member 62 is movable along the guide rails 61, 61, and a nozzle 57 is attached to the support member 62 so as to face vertically downward.
A vertical rotation shaft 63 is rotatably provided on one side of the upper portion in the casing 41. Gears 64A and 64A fitted to the upper and lower positions of the outer peripheral portion of the rotation shaft 63 are the same as those. Two upper and lower timing belts 65 are stretched across the gears 64B and 64B disposed on the other side of the casing 41 at a height. The upper and lower portions of the support member 62 are connected to the upper and lower timing bells 65, 65.
A gear 66 is fitted to the upper end of the rotating shaft 63, and a timing belt 69 is stretched over the gear 66 and a gear 68 on the motor 67 side disposed at an adjacent position. The operation of the motor 67 is controlled by a control device.
When the wheel shaft 2 is cleaned, a cleaning liquid supply source (not shown) is operated, so that the cleaning liquid W is sprayed from the spray nozzles 57 and 58 toward the wheel shaft 2. At that time, since the control device rotates the motor 67 forward and backward, the injection nozzle 57 is reciprocated in a direction orthogonal to the rail 35 via the timing belt 65 and the like. Thus, the injection nozzle 57 is reciprocated along the longitudinal direction of the wheel shaft 2, and the cleaning liquid W is sprayed over the entire length direction of the wheel shaft 2.
Further, at the time of this cleaning, the cleaning liquid W is sprayed from the lower spray nozzle 58 and at the same time the motor 46 of the rotating mechanism 37 is rotated, so that the wheel shaft 2 rotates around the axis via the support rollers 36A and 36B. Is done. Therefore, the cleaning liquid W is uniformly sprayed and cleaned toward the entire outer surface of the wheel shaft 2 and the gear box 4.
In the present embodiment, a gas-liquid mixed liquid in which water and baking soda are mixed in the nozzle is used as the cleaning liquid W, and the operation of a supply means for a tank (not shown) storing water is controlled by the control means. Yes.

In this embodiment, in a state where both the shutters 43A and 43B are closed after carrying the wheel shaft 2 into the cleaning position A, the wheel shaft 2 is cleaned for the required time as described above. Then, when the required time has elapsed, the spraying of the cleaning liquid W is stopped, the operations of the motors 46 and 67 are also stopped, and the cleaning operation is completed.
At the time when the cleaning operation is completed, the wheel shaft 2 is continuously supported by the support rollers 36A and 36B. In this embodiment, the wheel shaft 2 after the cleaning is sent out and the central portion 35A of both rails 35 is inclined obliquely upward by the mechanism 45. By raising, it is sent out from the cleaning position A toward the carry-out position C.
As described above, the central portion 35A of the rails 35 can be swung obliquely upward from the horizontal state. As shown in FIG. 1, an air cylinder 72 is disposed below the rail 35 at the cleaning position A, and a swing lever 73 is connected to the tip of a piston 72 </ b> A of the air cylinder 72. When the air cylinder 72 is actuated by the control device after the shutter 43B is opened and the piston 72A is advanced to the forward end after the cleaning is completed, the central portion 35A of the rails 35 is inclined in conjunction with the swing lever 73. Since it is swung upward, the wheel 2B supported by both of the central portions 35A is sent out on the rail 35 toward the carry-out position C.
Thereafter, when the control device stops the operation of the air cylinder 72, the piston 72A moves backward, and accordingly, the central portion 35A of the rail 35 returns from the inclined state to the original horizontal state.

Next, unloading means 8 having substantially the same configuration as the above-described loading means 7 is provided at the unloading position C, and an intermediate deck is also provided between the unloading means 8 and the main body 3 of the cleaning position A. 124 is arranged.
The configuration of the intermediate deck 124 is the same as the configuration of the intermediate deck 24 disposed between the carry-in position B and the cleaning position A, and the rail 125 is horizontally provided on the intermediate deck 124 on the extension of the rail 35 at the cleaning position A. It has been.
A movable support member 114 having the same configuration as that of the movable support member 14 is swingably provided at the position of the downstream end portion of the intermediate deck 124.
The movable support member 114 is movable between a support position that is substantially horizontal by an air cylinder (not shown) similar to the air cylinder 26 and a retreat position that is substantially vertical and deviates from the support position. A rail 114 </ b> A similar to the support member 14 is provided on the upper surface of the movable support member 114. When the movable support member 114 is moved from the retracted state to the horizontal support position by an air cylinder (not shown), the rail 124A is positioned on the extension of the rail 125 of the intermediate deck 124 (see FIG. 1). .
The carry-out means 8 is configured in the same manner as the carry-in means 7, and includes a fixed frame 111, a lift frame 112 that can be lifted and lowered, a lift mechanism 113 that lifts and lowers the fixed frame 111, and the movable support member 114. Each member corresponding to the carry-in means 7 in the carry-out means 8 is assigned a member number obtained by adding 100.
The configurations of the fixed frame 111, the lifting frame 112, the lifting mechanism 113, and the movable support member 114 are the same as those of the fixed frame 11, the lifting frame 12, the lifting mechanism 13, and the movable support member 14 included in the carrying-in means 7, and therefore the detailed configuration is provided. Description is omitted.
In the carry-out means 8, the fixing means 12B and the push-out mechanism 15 on the carry-in means 7 side are omitted. Instead, the wheel shaft 2 is pushed out from the carry-out position C to the adjacent downstream side on the floor F at the carry-out position C. A mechanism 119 is disposed so as to be swingable.
While the elevating mechanism 112 is raised to a required height by the elevating mechanism 113 and the movable support member 114 is positioned at the substantially horizontal support position, the delivery mechanism 45 at the cleaning position A moves from the cleaning position A to the unloading position C. When the washed wheel shaft 2 is sent out, the wheel shaft 2 rolls on the rail 125 of the intermediate deck 124 and then is fed onto the rail 114A of the movable support member 114 at the carry-out position C. .
Then, both bearing seats 2Aa on the wheel shaft 2 are located above the support portion 112A of the lifting frame 112 at the carry-out position C. Thereafter, when the elevating frame 112 rises and the support portion 112A supports the bearing seat 2Aa of the wheel shaft 2, the movable support member 114 is retracted from the support position in the substantially horizontal state to the retracted position in the substantially vertical state.
Thereafter, when the elevating frame 12 is lowered to the lower end position by the elevating mechanism 113, the wheel shaft 2 is placed on the floor F at the carry-out position C, and the support portion 112A of the elevating frame 112 is moved from the bearing seat 2Aa of the wheel shaft 2. Separate.
Thereafter, since the pushing mechanism 119 is swung in the carrying-out direction, the wheel shaft 2 is pushed from the carrying-out position C to the adjacent downstream side by the pushing mechanism 119. In this manner, the washed wheel shaft 2 is carried out to the adjacent downstream side by the carrying-out means 8.

According to the wheel shaft cleaning apparatus 1 of the present embodiment configured as described above, the wheel shaft 2 can be cleaned in a state where the wheel shaft 2 is supported at the cleaning height above the floor F at the cleaning position A. . Therefore, the wheel shaft 2 can be cleaned without installing an underground pit on the floor F at the cleaning position A.
In addition, according to the present embodiment, there is no need to provide an underground pit, so the installation location of the wheel shaft cleaning device 1 can be changed or moved to another vehicle base.
The carry-out means 8 in the above embodiment may be omitted. In that case, the wheel shaft 2 cleaned at the cleaning position A is returned to the loading position B via the rail 25 of the intermediate deck 24 on the carry-in side, and the wheel shaft 2 is moved to the floor F by the lifting frame 12 by an operation reverse to that at the carry-in. It becomes the composition which returns to.
