Methods have been proposed in which the displacement is performed by the actuator, or by remote control using a special rope, but both require a dedicated power unit for the purpose of displacing the pusher arm. shall be.

The present invention provides a pusher arm on the main body of a conveying device that is conveyed on a guide rail provided along a main line rail, and by changing the moving direction of a wire rope, the pusher arm is automatically conveyed on a main line rail. The pusher arm is designed to rotate to the engaging position or retracted position with the wheels of the vehicle being used, and is particularly useful for cushioning the impact after the pusher arm has been rotated to the engaging position with the wheel, and for retracting the pusher arm from the wheel to the retracted position. The purpose is to ensure smooth rotation of the pusher arm during rotation, and to enable vehicles to be transported on the main line rail without any modification or adverse effects on the existing main line rail. In order to achieve this objective, the present invention has the following configuration. Outside the main rail,
A guide rail is provided parallel to the guide rail at a predetermined interval, and a main body of the conveying device is provided to be conveyed on the guide rail. A pair of guide rollers are provided at both ends of the main body of the conveying device and are in contact with the side surface of the head of the guide rail and are rotatable along the side surface of the head of the guide rail. One of the pair of guide rollers described above is constituted by a rotatable resistance roller that is pressed against the side surface of the rail head with a predetermined spring constant. The lower part is rotatably pin-coupled to a predetermined point on the conveyor body.
A pusher arm is provided that slopes upward in the direction of the main rail. An L-shaped cross-section lever with a closed surface on the pusher arm side is provided on the conveyor main body portion on the main rail side close to the pusher arm. The lower end of the pusher arm and the lower end of the L-shaped lever are connected by a link. A rope fixing fitting, in which a fixing part, a connecting part, and a base part are integrally formed in sequence when viewed from the main rail side, is fixed to the opposing part of the L-shaped lever that faces the closed surface. A predetermined point of the wire rope for transporting the transport device is fixed to the fixing part of the rope fixing fitting, and a through hole of a predetermined length is formed in the longitudinal direction of the horizontal member of the L-shaped lever on the side opposite to the pusher arm along the through hole. The connecting part of the rope fixing fitting is formed to be movable in the direction of the pusher arm or in the opposite direction. A predetermined distance is set between the base of the rope fixing metal fitting and the facing surface of the main body of the conveying device that faces the base in the conveying direction.
One end is fixed to the opposite part of the conveying apparatus main body, and the other end passes through the base of the rope fixing fitting and the right angle member part of the L-shaped lever that faces the base in the conveying direction, and is conveyed to the opposite part of the conveying apparatus main body. A support shaft fixed to the main body portions of the conveying device facing each other in the direction is provided so that the base of the rope fixing fitting and the L-shaped lever can move in the pusher arm direction and the opposite direction along the support shaft. A cushioning material having a predetermined spring constant is inserted between the base of the rope fixing metal fitting and the right angle member of the L-shaped lever facing the base in the conveyance direction. The distance between the base of the rope fixing metal fitting and the opposing surface of the main body of the conveying device that opposes it in the conveying direction is such that the pusher arm can be rotated to the retracted position about the pin in cooperation with the resistance roller, and is L-shaped. The length of the through hole formed in the longitudinal direction of the horizontal member of the lever allows engagement with the wheels of the pusher arm in cooperation with the cushioning material inserted between the base of the rope fixing fitting and the right angle member of the L-shaped lever. It is set to buffer the impact that occurs when a rear-end collision occurs with a wheel after it has been rotated into position.

The present invention will be explained according to the embodiments shown in FIGS. 1 to 3.

1 to 3, reference numeral 1 indicates a main line rail, and reference numeral 2 indicates wheels of a vehicle running on the main line rail 1. In FIGS. 4
is one guide rail laid outside the main line rail 1, and is arranged in parallel with the main line rail 1 with a predetermined spacing therebetween. Reference numeral 3 denotes a main body of the conveying device, and one end of the main body 3 of the conveying device is provided with a pair of guide rollers 5 which are in contact with the side surface of the head of the guide rail 4 and are rotatable along it, and a pair of guide rollers 5 are provided at the other end. A pair of rollers is also provided. Like the guide roller 5, one of the pair of rollers is a guide roller 5 that is in contact with one head side of the guide rail 4 and can rotate along it, and the other roller teeth,
A resistance roller 19 is in contact with the side surface of the head of the guide rail 4 facing the one roller 5, and is rotatable along the side surface of the head. The resistance roller 19 is rotatably attached to a support fitting 20 provided on the conveyance device main body 3 by a pin 21. The support fitting 20 is pressed toward the side surface of the head of the guide rail 4 by a load spring 22 having a predetermined spring constant. Reference numeral 6 denotes a pusher arm which is tilted upward in the direction of the main rail, and whose lower predetermined point is rotatably attached to a predetermined point on the main body of the conveying device by means of a pin 10.
On the side surface of the pusher arm 6 facing the main rail, there is a pusher roller 7 that rotates in contact with the lower circumference of the vehicle's wheels without contacting the tread surface of the main rail 1.
and a vertical load receiving roller 8 that is in contact with the tread surface of the main line rail 1 and can rotate along it, and the main line rail 1.
A left-right load receiving roller 9 is provided which is in contact with the side surface of the head of the head and is rotatable along the side surface of the head. Pusher arm 6 in FIG. 1 of the conveyor main body 3
A recess 31 is formed on the left side of the recess 31, and the lever 11 having an L-shaped cross section and having one end surface 111 closed is disposed in the recess 31. The lower end of the pusher arm 6 and the lower end of the lever 11 are connected by a link 12. 13 and 14 are pins. The base 161 of the rope fixing fitting 16 is placed inside the lever 11. Connecting portion 1 of the base 161 formed as one piece therewith
62 protrudes to the outside from a through hole 112 having a predetermined length in the longitudinal direction formed in the lever 11, and is connected as a unit with a fixing portion 163 to the wire rope 15 for conveying the conveying device. 18 is the transport device main body 3
The support shaft 18 is a support shaft substantially parallel to the wire rope 15 fixed between the opposing surfaces of the recess 31 of 111"). The base 161 of the rope fixing fitting 16 and the lever 11 are movable along the support shaft 18. Lever 11
A cushioning material 17 made of a spring or the like is inserted between the closed end surface 111 of the rope fixing member and the opposing surface of the base 161 of the rope fixing fitting. Rope fixing bracket 1
As will be described later, the distance a between the left end surface of the base 161 of 6 in FIG. Further, a length b obtained by subtracting the width of the connecting portion 162 of the rope fixing fitting 16 from the length in the longitudinal direction of the through hole 112 of the lever 11 is set to a clearance corresponding to a buffer stroke to be described later.

In the state shown in FIG. 1, the left end surface of the lever 11 and the left end surface of the base 161 of the rope fixing fitting 16 are in a line shape perpendicular to the longitudinal axis of the guide rail 4.

In such a configuration, in the state shown in FIG. 1, the wire rope 15 is moving in the direction A by the drive of a drive device (not shown), and the conveyance device main body 3 is conveyed in the direction A on the guide rail 4, and the vehicle A by the pusher roller 7 that engages with the wheel 2
being transported in the direction.

Let us now consider the state before the start of transport. In this case, the pusher roller 7 and the wheel 2 are separated by a certain distance, the wire rope 15 is sent in the direction A at a predetermined speed, and the conveyor main body 3 is sent at a predetermined speed, either while stopped or at a speed slower than the wire rope 15. Assume that you are approaching the wheel 2 that is running. When the pusher roller 7 collides with the wheel 2,
The impact caused by the rear collision is applied to the lever 11 via the pusher arm 6, and the impact is applied to the lever 11 through the pusher arm 6.
is moved to the left in FIG. In this case, in the present invention, since the spring constant and clearance b of the buffer material 17 are set to sufficiently buffer the impact, the first
The right end wall in the figure buffers at least before contacting the opposing surface of the base 161 of the rope fixing fitting 16, and returns to the state shown in FIG. 1 after the buffer. After that, as mentioned above, the wheel 2 is moved to the pusher roller 7.
is transported in direction A at a predetermined speed. After transporting the vehicle to a predetermined position, operate the drive device to stop the wire rope 15 from moving in the A direction, and move the wire rope 15 in the opposite direction to B.
change direction. Thereby, wire rope 1
Rope fixing bracket 1 fixed in the predetermined position of 5
6 in the direction B acts until the left end surface of the base 161 of the rope fixing fitting 16 in FIG. 1 abuts against the opposing end surface of the conveying device main body. The leftward movement is transmitted to the pusher arm 6 via the link 12, the pusher arm 6 rotates in the c direction about the pin 10, and the pusher roller 7 is retracted from the engagement position with the wheel 2 and displaced to the storage position. It will be done. However, in order for this to occur, it is necessary to make the running resistance of the main body of the conveying device greater than that of the rope.

In the present invention, with the spring force of the load spring 22,
The resistance roller 19 is pressed toward the side surface of the head of the guide rail 4 to apply a predetermined running resistance to the main body 3 of the conveying device, and the clearance a is set at a distance that allows the pusher arm 6 to be sufficiently rotated to the retracted position. Therefore, it is possible to smoothly move to the retracted position. This displacement is maintained as long as the wire rope 15 continues to move in the B direction. The conveyor body 3 with the pusher arm 6 in the retracted position moves in the B direction, and when it reaches the rear position of the freight car to be conveyed, changes the moving direction of the wire rope 15 to the A direction. As a result, the rope fixing fitting 16 is displaced in the direction A, and the right end surface of the lever 11 abuts against the opposing surface of the conveyor main body, causing the pusher arm 6 to rotate in the opposite direction C around the pin 10 via the link 12. As shown in FIG. 1, the pusher arm 6 is displaced to the engagement position with the wheel.

According to the present invention, in order to displace the pusher arm 6 to the extended position and the retracted position, the pusher arm 6 can be automatically moved to a predetermined position by simply changing the moving direction of the wire rope without using a dedicated mechanism using a power device. Since the displacement is possible, the technical effect is remarkable in conjunction with the simplification of the mechanism.
