DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0011] 1 to 5 show a first embodiment of the present invention. In this embodiment, the wing opening and closing device for a wing vehicle according to the present invention is configured to open and close the wing of the wing vehicle shown in FIG.

[0012] As shown in Figure 1, a wing vehicle 1 has a wing body (hereinafter referred to as the body) 3 mounted on the bed of a truck 2, and a pair of wings 5 ​​are supported on the left and right side walls of the body 3 so as to be freely rotatable by support shafts 4 and are installed so as to open and close diagonally upward in a gull-wing configuration. Since the left and right wings 5, 5 have the same structure and are arranged symmetrically, the left wing 5 will be representatively described below. A pair of electric cylinder devices 10, 10 are disposed on the front and rear walls of the body 3, respectively. One end of each of the electric cylinder devices 10, 10 is pivotally attached to the body 3, and the other end is pivotally attached to the wing 5. In other words, the wing 5 is provided with a pair of electric cylinders 10, 10 on the front and rear. The device 10 is opened and closed by extending and contracting the device 10.

[0013] 2, the electric cylinder device 10 includes an externally threaded shaft 12 rotatably supported within a cylinder 11, an internally threaded body 13 that is coupled to the externally threaded shaft 12 by a ball screw and moves linearly with the rotation of the externally threaded shaft 12, a piston 14 fixed to the internally threaded body 13, and a motor 16 that drives the externally threaded shaft 12 to rotate via a reduction gear 15. The reduction gear 15 and the motor 16 are installed and fixed to a base 17, and a body side mounting portion 18 is provided on the base 17 so as to protrude from the end face opposite the reduction gear 15 and the motor 16. The electric cylinder device 10 is arranged horizontally near the ceiling of the body 3, and the body side mounting portion 18 is rotatably mounted on the body 3 by a bracket 19, while the connecting shaft 24 described later is rotatably mounted on the wing 5 by a bracket 36.

[0014] 2 and 3, a cylindrical connector 20 is arranged coaxially with the end of the piston 14 protruding from the cylinder 11 and is fixed by a screw joint 21. A cylindrical bearing hole 22 is formed in the connector 20 and arranged coaxially with the end of the piston 14. A thrust bearing 23 is arranged coaxially on the bottom surface of the bearing hole 22. A base portion 24a of a cylindrical connecting shaft 24 is rotatably fitted into the bearing hole 22 with its end face in sliding contact with the thrust bearing 23, and a tip portion 24b of the connecting shaft 24 protrudes from the bearing hole 22. The connecting shaft 24 is prevented from coming off the connecting body 20 by a stopper ring 25 attached to the end portion of the bearing hole 22.

[0015] A pair of connecting shaft side through holes 26, 26 are opened in the base 24a of the connecting shaft 24, and are arranged symmetrically with respect to the axis in a plane perpendicular to the axis. A pair of connecting body side through holes 27, 27 are opened in the connecting body 20 at positions facing the connecting shaft side through holes 26, 26 so as to form a straight line with the connecting shaft side through holes 26, 26. A U-shaped pin 28 serving as a rotation-preventing member is slidably inserted into the connecting shaft-side through-holes 26, 26 and the connecting body-side through-holes 27, 27. A positioning ring 29 is fixed to the curved side of the U-shaped pin 28, and the positioning ring 29 abuts against the side surface of the connecting body 20 to position the U-shaped pin 28. A stopper ring 30 is attached to one tip of the U-shaped pin 28 via a washer 30A, and the stopper ring 30 prevents the U-shaped pin 28 from coming out of the through-holes 26, 27.

[0016] A rectangular prism-shaped turnbuckle 31 is fitted to the tip 24b of the connecting shaft 24 and arranged coaxially, and the turnbuckle 31 is connected by a screw connection portion 32 so that its position in the longitudinal direction can be adjusted. A tool engagement portion 33 is formed on the outer periphery of the turnbuckle 31 to which a tool such as a wrench (not shown) can be engaged. By engaging a tool with the tool engagement portion 33 and rotating the turnbuckle 31, the distance between the turnbuckle 31 and the connecting body 20 can be adjusted. This distance adjustment operation allows the overall length of the wing opening / closing device 10 to be adjusted. The turnbuckle 31 has a mounting hole 34 formed perpendicular to the axis, and a pivot 35 is rotatably fitted into the mounting hole 34. The pivot 35 is rotatably supported by a bracket 36 fixed to the wing 5.

[0017] Next, the operation will be described.

[0018] The electric cylinder device 10 is arranged horizontally near the ceiling of the body 3, the body side mounting portion 18 is rotatably mounted on the body 3 by a bracket 19, and the turnbuckle 31 is rotatably mounted on the wing 5 by a bracket 36. At this time, the worker manually rotates the turnbuckle 31 via the tool engagement portion 33 to turn the The wing 5 can be brought into close contact with the body 3 by adjusting the distance between the buckle 31 and the connecting body 20, i.e., the overall length of the wing opening / closing device 10.

[0019] When the wing 5 is in close contact with the body 3 and closed, the wing opening / closing device 10 is in a state in which the piston 14 is housed in the cylinder 11, as shown in FIG. When the motor 16 is rotated in the forward direction to open the wings 5 ​​, the male screw shaft 12 is rotated at a reduced speed via the reducer 15 . At this time, since the female threaded body 13 is prevented from rotating by the wing 5 via the piston 14, the connecting body 20, the connecting shaft 24, the turnbuckle 31 and the bracket 36, the female threaded body 13 moves within the cylinder 11 following the rotation of the male threaded shaft 12. The piston 14 fixed to the female threaded body 13 is protruded from within the cylinder 11 by the movement of the female threaded body 13, and the wing opening and closing device 10 opens the wing 5. When the female threaded body 13 reaches the end within the cylinder 11, the motor 16 is automatically stopped. When the wing opening and closing device 10 shown in Figure 4 is extended, the load of the wing 5 is applied to the female threaded body 13, but since the female threaded body 13 is prevented from rotating by the wing 5, the wing opening and closing device 10 maintains the open position of the wing 5.

[0020] When the motor 16 is rotated in the reverse direction to close the wings 5, the male screw shaft 12 is rotated via the reducer 15 at a reduced speed in the direction opposite to that during the wing opening operation. At this time, since the female threaded body 13 is prevented from rotating by the wing 5 via the piston 14, the connecting body 20, the connecting shaft 24, the turnbuckle 31 and the bracket 36, the female threaded body 13 moves within the cylinder 11 following the rotation of the male threaded shaft 12. The piston 14 fixed to the female threaded body 13 is drawn into the cylinder 11 by the movement of the female threaded body 13, and the wing opening and closing device 10 closes the wing 5. When the female threaded body 13 reaches the end within the cylinder 11, the motor 16 is automatically stopped.

[0021] If the male screw shaft 12 does not rotate when the motor 16 for closing the wings 5 ​​is started, the wings 5 ​​do not close. In this case, after taking preliminary measures (e.g., hanging a rope on the wing 5) to deal with an unexpected closing operation of the wing 5 (e.g., a sudden drop of the wing 5), the U-shaped pin 28 of the emergency wing opening and closing device 10 is pulled out from the connector 20. Subsequently, if the other wing opening and closing device 10 is normal, the motor 16 of that wing opening and closing device 10 is rotated in reverse. When the U-shaped pin 28 is removed from the connecting body 20, the connecting shaft 24 becomes rotatable within the bearing hole 22 of the connecting body 20, and as shown in Figure 5, the piston 14 becomes rotatable, and the female threaded body 13 to which the load of the wing 5 is applied revolves around the male threaded shaft 12 and moves within the cylinder 11 along the male threaded shaft 12 at a preset speed. The piston 14 fixed to the female threaded body 13 is drawn into the cylinder 11 by the movement of the female threaded body 13, and the wing opening and closing device 10 closes the wings 5. When the female threaded body 13 reaches the end of the cylinder 11, the motor 16 of the normal wing opening and closing device 10 is automatically stopped. Thereafter, a follow-up procedure (for example, mechanically locking the wing 5) is carried out to deal with the unexpected opening operation of the wing 5 (for example, a malfunction of the motor 16), and the wing vehicle 1 is allowed to travel.

[0022] According to this embodiment, the following effects can be obtained.

[0023] (1) In an emergency when the male screw shaft does not rotate when the motor starts to close the wings, the U-shaped pin is removed from the connecting body, and the connecting body and the connecting shaft are placed in a freely rotatable state. This allows the female screw body to revolve and move within the cylinder along the male screw shaft, so that in an emergency The wing opening and closing device can be closed, thereby ensuring the operation of the wing vehicle after an emergency.

[0024] (2) Since the wing opening / closing device can be operated to close in an emergency by the simple task of removing the U-shaped pin from the connector, the wing can be closed in an emergency without having to perform the difficult task of manually rotating the male screw shaft.

[0025] (3) By using a dedicated extraction tool 40 (see FIG. 4) having a hook attached to the end of a long pole to extract the U-shaped pin, it is possible to avoid working at height.

[0026] (4) By attaching a turnbuckle to the connecting shaft, the overall length of the wing opening and closing device can be adjusted, so that the wing can be appropriately installed on the body of a wing-equipped vehicle.

[0027] FIG. 6 shows a second embodiment of the present invention. The present embodiment differs from the above-described embodiment in that the connecting shaft side insertion hole 26 is opened in the base 24a of the connecting shaft 24 at the center of a plane perpendicular to the axis, a pair of connector side insertion holes 27, 27 are opened in a position opposite the connecting shaft side insertion hole 26 of the connecting body 20 so as to form a straight line with the connecting shaft side insertion hole 26, a P-shaped pin 28A serving as an anti-rotation member is slidably inserted into the connecting shaft side insertion hole 26 and the connecting body side insertion holes 27, 27, and the curved portion of the P-shaped pin 28A is engaged with the outer periphery of the connecting body 20. According to this embodiment, it is possible to obtain an effect that the positioning ring 29, the stopper ring 30, and the washer 30A of the first embodiment can be omitted.

[0028] 7 to 9 show a third embodiment of the present invention. In this embodiment, the wing opening and closing device for a wing vehicle according to the present invention is configured to open and close the wing of the wing vehicle shown in FIG.

[0029] As shown in FIG. 7, the electric cylinder device 50 includes a cylindrical cylinder 51, an externally threaded shaft 52 arranged on the center line of the cylinder 51, an internally threaded body 53 arranged at one end within the cylinder 51 and threadedly engaged with the externally threaded shaft 52 to be coupled with a ball screw, and a sleeve-shaped rotor 54 connected to the internally threaded body 53 via a reduction mechanism 55 and a brake mechanism 57 and rotated by a motor 56 to linearly move the externally threaded shaft 52. The motor 56 includes a stator fixed to the cylinder 51 and an armature arranged rotatably inside the stator, and the sleeve-shaped rotor 54 is fixed to the inside of the armature.

[0030] 7, the end of the male threaded shaft 52 on the side of the female threaded body 53 protrudes from the end face of the cylinder 51, and a cylindrical connecting body 20 is arranged coaxially at the end of the male threaded shaft 52 protruding from the cylinder 11 and fixed by a threaded coupling portion 21. A cylindrical bearing hole 22 is formed in the connecting body 20 and arranged coaxially. A thrust bearing 23 is arranged coaxially on the bottom surface of the bearing hole 22. A base portion 24a of a cylindrical connecting shaft 24 is rotatably fitted into the bearing hole 22 with its end face in sliding contact with the thrust bearing 23, and a tip portion 24b of the connecting shaft 24 protrudes from the bearing hole 22. The connecting shaft 24 is prevented from coming off the connecting body 20 by a stopper ring 25 attached to the end portion of the bearing hole 22. A pair of connecting shaft side through holes 26, 26 are opened in the base 24a of the connecting shaft 24, and are arranged symmetrically with respect to each other on a plane perpendicular to the axis. A pair of connecting body side through holes 27, 27 are opened in the connecting body 20 at positions facing the connecting shaft side through holes 26, 26, so as to form a straight line with the connecting shaft side through holes 26, 26. A U-shaped pin 28 serving as a rotation prevention member is slidably inserted into the connecting shaft side through holes 26, 26 and the connecting body side through holes 27, 27.

[0031] A rectangular prism-shaped turnbuckle 31 is fitted to the tip 24b of the connecting shaft 24 and arranged coaxially, and the turnbuckle 31 is connected by a screw connection portion 32 so that its position in the longitudinal direction can be adjusted. A tool engagement portion 33 is formed on the outer periphery of the turnbuckle 31 to which a tool such as a wrench (not shown) can be engaged. By engaging a tool with the tool engagement portion 33 and rotating the turnbuckle 31, the distance between the turnbuckle 31 and the connecting body 20 can be adjusted. This distance adjustment operation allows the overall length of the wing opening / closing device 10 to be adjusted. The turnbuckle 31 has a mounting hole 34 formed perpendicular to the axis, and a pivot 35 is rotatably fitted into the mounting hole 34. The pivot 35 is rotatably supported by a bracket 36 fixed to the wing 5.

[0032] Next, the operation will be described. The electric cylinder device 50 is disposed horizontally near the ceiling of the body 3, the body side mounting portion 18 is rotatably mounted on the body 3 by a bracket 19, and the turnbuckle 31 is rotatably mounted on the wing 5 by a bracket 36. At this time, the worker manually rotates the turnbuckle 31 via the tool engagement portion 33 to adjust the distance between the turnbuckle 31 and the connecting body 20, i.e., the overall length of the wing opening and closing device 10, thereby bringing the wing 5 into close contact with the body 3.

[0033] When the wing 5 is in close contact with the body 3 and closed, the wing opening / closing device 50 is in a state in which most of the male screw shaft 52 is housed within the cylinder 51, as shown in FIG. When the motor 56 is rotated in the forward direction to open the wings 5 ​​, the internally threaded body 53 is rotated at a reduced speed via the reducer 55 . At this time, since the male threaded shaft 52 is prevented from rotating by the wing 5 via the connecting body 20, the connecting shaft 24, the turnbuckle 31, and the bracket 36, the male threaded shaft 52 is pushed out of the cylinder 51 by the rotation of the female threaded body 53. As the male threaded shaft 52 is pushed out of the cylinder 51, the wing opening and closing device 10 opens the wing 5. When the male threaded shaft 52 reaches a predetermined position, the motor 56 is automatically stopped. When the wing opening and closing device 50 shown in Figure 8 is extended, the load of the wing 5 is applied to the male threaded shaft 52, but since the male threaded shaft 52 is prevented from rotating by the wing 5, it cannot rotate, and therefore the wing opening and closing device 10 maintains the open position of the wing 5.

[0034] When the motor 56 is rotated in the reverse direction to close the wings 5, the female screw body 53 is rotated via the reducer 55 at a reduced speed in the direction opposite to that during the wing opening operation. At this time, since the male threaded shaft 52 is prevented from rotating by the wing 5 via the connecting body 20, the connecting shaft 24, the turnbuckle 31, and the bracket 36, the male threaded shaft 52 is drawn into the cylinder 51 by the rotation of the female threaded body 53. As the male threaded shaft 52 is drawn into the cylinder 51, the wing opening and closing device 50 closes the wing 5. When the male threaded shaft 52 reaches a predetermined position, the motor 56 is automatically stopped.

[0035] If the female screw body 53 does not rotate when the motor 56 for closing the wings 5 ​​is started, the wings 5 ​​will not close. In this case, after carrying out preparatory measures (e.g., attaching a rope to the wing 5) to deal with an unexpected closing operation of the wing 5 (e.g., a sudden drop of the wing 5), the worker pulls out the U-shaped pin 28 of the emergency wing opening and closing device 50 from the connector 20 as shown in Fig. 9. Next, if the other wing opening and closing device 50 is normal, the motor 56 of that wing opening and closing device 50 is rotated in reverse. When the U-shaped pin 28 is removed from the connecting body 20, the connecting shaft 24 becomes rotatable within the bearing hole 22 of the connecting body 20, so that the male threaded shaft 52 is pressed against the female threaded body 53 by the load of the wing 5. As the male threaded shaft 52 is pulled into the cylinder 51 at a preset speed while rotating, the wing opening and closing device 50 closes the wing 5 as the male threaded shaft 52 is pulled into the cylinder 51. When the male threaded shaft 52 reaches a predetermined position, the motor 56 of the normal wing opening and closing device 50 is automatically stopped. Thereafter, a follow-up procedure (for example, mechanically locking the wing 5) is carried out to deal with the unexpected opening operation of the wing 5 (for example, a malfunction of the motor 16), and the wing vehicle 1 is allowed to travel.

[0036] According to this embodiment, the same effects as those of the first embodiment can be obtained.

[0037] It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit and scope of the present invention.

[0038] For example, the anti-rotation member is not limited to a U-shaped pin or a P-shaped pin, but may be a split pin or a bolt.

[0039] The ball screw connection for reducing friction between the male screw shaft and the female screw body may be omitted in some cases.

[0040] In the above embodiment, a wing vehicle in which a pair of wing opening and closing devices are arranged at the front and rear of the body has been described, but the present invention can also be applied to wing vehicles, etc. in which a single wing opening and closing device is arranged in the center of the body.
