A pair of long holes 34 extending in the left-right direction are formed in the upper part of the stopper member 33. This long hole 34
The shaft 463 of the link mechanism 46 to be described later is engaged with.

A stopper driving means 4 for switching the first stopper 2 and the second stopper 3 between an operating state and a non-operating state is provided above the movable rail 12. The stopper driving means 4 has a main component including a hydraulic cylinder 41 which is a driving source of the stopper driving means 4.
The first stopper 2 is operated (the state shown in FIG. 1) / non-operated (the state shown in FIG. 3), and the second stopper 3 is operated (the state shown in FIG. 1) / non-operated (the figure). (The state shown in FIG. 3). Hereinafter, the configuration of the stopper driving means 4 will be described.

A bracket 4 is provided above the movable rail 12.
Numeral 0 is fixed by bolting, and a hydraulic cylinder 41 as a driving source of the stopper driving means 4 is fixed to the bracket 40. This hydraulic cylinder 41
For example, it is operated by a hydraulic drive unit (not shown) installed above the movable rail 12. The drive source is not limited to a hydraulic cylinder, but may be a pneumatic cylinder, a motor,
An electrically driven device such as a solenoid may be used.

The stopper driving means 4 has a moving body 42 which reciprocates in the longitudinal direction (left and right direction) of the movable rail 12 by driving the hydraulic cylinder 41.

The moving body 42 includes a main body 43 having a substantially rectangular shape in a plan view, and a support plate 4 erected on the upper part of the main body 43.
4, three pairs of free rollers 45 a, 45 b, and 45 c, which are rotatably installed below the main body 43, and a support plate 44.
A link mechanism 46 connected to the upper end of the main body 45, a pair of support plates 47 erected on the upper left side of the main body 45, and both support plates 47
And a bar 48 erected in the front-rear direction near the upper part.

The tip of the piston 411 of the hydraulic cylinder 41 is fixed to the support plate 44 by a fixture 412.
As the piston 411 expands and contracts due to the operation of the hydraulic cylinder 41, the moving body 42 reciprocates in the left-right direction. Along with the movement of the moving body 42, the first operation principle will be described later.
Each stopper member 2 of the stopper 2 and the second stopper 3
The rotation of the first and second stoppers 2 and 3 is switched between the rotation of the first and second stoppers 3 and 33.

The moving body 42 is located between the two supporting plates 31 and, when the moving body 42 moves, each free roller 45
a, 45b, and 45c abut on the opposing inner surfaces of both support plates 31, respectively, and rotate. Accordingly, the movement of the moving body 42 in the front-rear direction with respect to the movable rail 12 is restricted, and the moving body 42 moves only in the left-right direction.

The free rollers 45a, 45b, 45
The installation of c contributes to the restriction of the moving path of the moving body 42, the reduction of the moving resistance of the moving body 42, and the smooth movement thereof.

The moving range of the moving body 42 is such that the left end of the moving body 42 is located near the right side of the boundary 10 when the piston 411 is in the most contracted state, and the moving range when the piston 411 is in the most extended state. 42 enters the fixed rail 11 side beyond the boundary portion 10, particularly between the two support plates 21,
The free rollers 45a are located at positions where they contact the opposing inner surfaces of the support plates 21, respectively.

The left and right movement limit positions of the moving body 42 are detected by limit switches 413 and 414 provided on the hydraulic cylinder 41, and are controlled by control means (not shown) so as to stop at that position. .

The link mechanism 46 includes a shaft 461 installed at the upper end of the support plate 44, a pair of links 462 whose one end is rotatably supported with respect to the shaft 461,
62 and a shaft 463 supported at the other end. The shaft 463 extends in the front-rear direction, and its length is set longer than the width of the stopper member 33. Then, both ends of the shaft 463 are respectively inserted into the long holes 34,
It is movable along the elongated hole 34.

The stopper driving means 4 has a return means 5 for returning the first stopper 2 to the operating state.
This return means 5 is mainly composed of a coil spring 51. The lower end of the coil spring 51 is supported on the upper part of the fixed rail 11, and the upper end of the coil spring 51 is supported on the top plate 26 of the stopper member 23 via the hook 52. Then, the contraction force of the coil spring 51 urges the stopper member 23 at the retracted position to rotate counterclockwise in FIG. 3 and return to the regulation position.

In the present embodiment, the stopper member 23 returns to the regulating position or a position near the regulating position by the rightward movement of the moving body 42 due to the reversible action of the plate cam 24 described later. By means 5, the stopper member 23 can be reliably returned to the regulation position.
Therefore, it can be said that the return means 5 assists the return of the first stopper 2 to the operating state (return assist means).

Guide plates (guide members) 6 are provided at the lower right ends of the pair of support plates 21 as alignment means for aligning the ends of the fixed rail 11 and the movable rail 12, respectively. . The two guide plates 6 are inclined so as to widen the space to the right so that the moving body 42 can be received. The guide plate 6 is formed by deforming the support plate 21.

When the moving body 42 enters the fixed rail 11 side beyond the boundary 10, the rollers 45 a abut against the opposing inner surfaces of the guide plates 6, respectively.
The position in the front-rear direction is gradually adjusted, and both support plates 21 are adjusted.
Inserted in the center between. Thereby, the position of the movable rail 12 in the front-rear direction with respect to the fixed rail 11 is aligned, and the ends of the movable rail 12 and the fixed rail 11 coincide with each other.

The moving body 42 is a component of the stopper driving means 4 and also functions as a fixing means for fixing the position of the movable rail 12 with respect to the fixed rail 11 in the front-rear direction. The fixing means by the moving body 42 shares the hydraulic cylinder 41 as a driving source with the stopper driving means 4 and cooperates with the stopper driving means 4.

When the moving body 42 enters the fixed rail 11 side beyond the boundary portion 10, the moving body 42 including the roller 45a
Is inserted or fitted between the support plates 21. Thereby, the position of the movable rail 12 in the front-rear direction with respect to the fixed rail 11 via the moving body 42 is fixed.

As described above, since the fixing means is shared with the stopper driving means 4, it contributes to simplification of the structure.

Next, the operation of the connecting device 1 will be described. As shown in FIGS. 1 and 5, the stopper member 23,
When the stop 33 is in the restricting position (the first stopper 2 and the second stopper 3 are in the operating state), the traveling body 18 on the fixed rail 11 abuts on the stopper member 23 even if it moves rightward, and the boundary is further extended. Cannot move in the direction of part 10, and
The traveling body 18 on the movable rail 12 abuts against the stopper member 33 even when moved to the left, and cannot move further in the boundary 10 direction. Accordingly, regardless of the position of the movable rail 12 in the front-rear direction with respect to the fixed rail 11, the traveling body 18 is fixed even if the position of the fixed rail 11 and the movable rail 12 in the front-rear direction do not match. It is prevented from dropping from the movable rail 11 or the movable rail 12, and the safety is high.

If necessary, the movable rail 12 is moved forward or backward by rotating the roller 17 so that the position of the movable rail 12 in the front-rear direction with respect to the fixed rail 11 is substantially matched.

Next, as shown in FIGS. 2 and 6, the hydraulic cylinder 41 is operated to extend the contracted piston 411. Thus, the moving body 42 located at the rightward movement limit starts moving leftward. Moving body 42
First, the roller 45a enters the fixed rail 11 side beyond the boundary portion 10 and is inserted between the right ends of the two guide plates 6 (the portion where the distance between the two guide plates 6 is the largest). As the roller 45a moves between the two guide plates 6 in the left direction, that is, in the direction in which the distance between the two guide plates 6 decreases, the position of the moving body 42 in the front-rear direction is gradually adjusted. Inserted in the center between. As a result, the position of the movable rail 12 in the front-rear direction with respect to the fixed rail 11 is aligned (finely adjusted), and the ends of the movable rail 12 and the fixed rail 11 coincide with each other.

Further, by moving the moving body 42 to the left, the link mechanism 46 also moves in the same direction. At this time, the shaft 463 moves to the left end of the long hole 34 along the long hole 34.

Next, when the piston 411 is further extended from the state shown in FIGS. 2 and 6, and the moving body 42 is moved leftward to its movement limit, as shown in FIGS. The stopper 2 and the second stopper 3 become inoperative, and the movable rail 1 is moved by the fixing means.
The position of the second fixed rail 11 in the front-rear direction is fixed.

That is, on the movable rail 12 side, the shaft 463 of the link mechanism 46 that moves leftward together with the moving body 42
Presses the left end of the long hole 34, whereby the stopper member 33 rotates around the shaft 32 in the counterclockwise direction in FIG. 3 and moves to the retracted position.

On the other hand, on the fixed rail 11 side,
13A, first, as shown in FIG. 13A, the bar 48 comes into contact with the first cam surface 241 of the plate cam 24. Then, as shown in FIG. 241
To rotate the plate cam 24 clockwise. In this rotation, the cam surface with which the bar 48 comes into contact is the first cam surface 2
From 41, it moves to the second cam surface 242.

Since the stopper member 23 is fixedly installed on the plate cam 24, the stopper member 23 rotates integrally with the plate cam 24. Therefore, the stopper member 23 is
3 rotates clockwise in FIG. 3 around the shaft 22 against the contraction force (biasing force) of FIG. When the stopper member 23 is at the retracted position, the coil spring 51 is in an extended state, and urges the stopper member 23 to rotate counterclockwise in FIG.

As described above, when the stopper members 23 and 33 come to the retracted positions, the traveling body 18 can freely move between the fixed rail 11 and the movable rail 12 through the boundary 10. It becomes possible.

In a state where the moving body 42 has moved to the leftward movement limit, as shown in FIG.
It enters between the support plates 21, and the free rollers 45 a are sandwiched between the inner surfaces of the support plates 21 facing each other. Thereby, the position of the movable rail 12 in the front-rear direction with respect to the fixed rail 11 is fixed. Therefore, when the traveling body 18 moves between the fixed rail 11 and the movable rail 12, an accident such that the rails 11 and 12 are displaced in the front-rear direction and the traveling body 18 falls off is prevented, and the safety is high.

Further, as described above, since the movable rail 12 and the fixed rail 11 are aligned so that the ends thereof coincide with each other, the traveling body 18 passes through the boundary portion 10 and the fixed rail 11, When moving between the movable rails 12, the movement can be performed smoothly, and in particular, it can pass through the boundary 10 while suppressing generation of vibration and noise.

Next, when the above-mentioned movement of the traveling body 18 is completed, as shown in FIGS. 4 and 8, the first stopper 2 and the second stopper 3 are returned to the operating state again, and the fixing means is used. The fixing of the movable rail 12 to the fixed rail 11 is released.

First, the traveling body 18 is connected to the stopper member 23,
When the pivot 33 rotates, it is retracted to an appropriate position that does not interfere with it, and in this state, the hydraulic cylinder 41 is operated to contract the piston 411 in the extended state. As a result, the moving body 42 starts moving rightward.

With this movement, on the movable rail 12 side,
The shaft 463 of the link mechanism 46 moves rightward together with the moving body 42 to release the pressing of the left end of the long hole 34, moves rightward in the long hole 34, contacts the right end of the long hole 34, and presses. .
Thereby, the stopper member 33 rotates clockwise in FIG. 4 around the shaft 32 and moves to the regulation position.

On the other hand, on the fixed rail 11 side,
Is moved to the right, and the pressing of the first cam surface 241 and the second cam surface 242 is released, whereby the stopper member 23 has its own weight and the contraction force (the urging force) of the coil spring 51. ), It rotates around the shaft 22 in the counterclockwise direction in FIG. In the course of this rotation operation, FIG.
As shown in (c), the bar 48 comes into contact with the third cam surface 243 and presses the third cam surface 243 upward. Thereby, the plate cam 24 and the stopper member 2 fixed thereto are
3 forcibly receives a clockwise rotation force. Therefore, in combination with the urging force of the coil spring 51, the stopper member 23
Returns to the regulated position without fail.

When the stopper members 23 and 33 return to the regulating positions in this way, as described above, the movement of the traveling body 18 is regulated, and
1 or the movable rail 12 is prevented from falling off.

As the moving body 42 moves rightward, the left end of the moving body 42 including the roller 45a is
In a state where the moving body 42 has been moved to the rightward movement limit, the left end of the moving body 42 exceeds the boundary 10 and is located near the right side thereof. Thereby, the fixing of the movable rail 12 to the fixed rail 11 in the front-rear direction by the fixing means is released.

By releasing the fixing, the movable rail 12 can be moved in the front-rear direction along the traveling rail 14. In this case, since the stopper members 23 and 33 are at the regulating positions, the traveling body 18 is prevented from falling off from the fixed rail 11 or the movable rail 12, and the safety is high.

In the present invention, a plurality of fixed rails similar to the fixed rail 11 are installed at predetermined intervals in the front-rear direction, and the movable rail 12 moves in the front-rear direction.
It can be applied to a configuration that can be selectively connected (coupled) to one of them. Further, such fixed rails 11 may be installed on both ends of the movable rail 12, respectively. In these cases, the above-described second stopper 2, guide plate 6, return means 5, and the like are installed at the ends of each fixed rail 11 facing the boundary 10 respectively.

In such a configuration, by selectively connecting the movable rail 12 to a predetermined fixed rail 11, the traveling body 18 can be arbitrarily set in the area where each fixed rail 11 is installed and the movable area of the movable rail 12. Therefore, for example, a non-conveyed object such as a building material, an industrial product (or a part) can be two-dimensionally conveyed by the crane device 200 supported by the traveling body 18.
In the state where the movable rail 12 and the fixed rail 11 are connected and the state where the connection is released, the first stopper 2,
The second stopper 3, the fixing means, etc. operate as described above,
Demonstrate its function.

In particular, regardless of the position of the running body 18 on the fixed rail 11 and the movable rail 12, the function of the first and second stoppers 2 and 3 prevents the running body 18 from falling off, thereby improving safety. Movable rail 1
The movement of the movable rail 12 is less likely to be restricted by the movement of the movable body 12, for example, while the traveling body 18 is traveling.
Therefore, work efficiency (transportation efficiency) can be improved.

In this configuration, when the stopper driving means 4 including the hydraulic cylinder (drive source) 41 is installed on the fixed rail 11 side, the number of stopper driving means corresponding to the number of the fixed rails 11 is set. It is necessary to provide the main components of the stopper driving means 4 including the hydraulic cylinder (drive source) 41 as in the present embodiment.
When the fixed rail 11 is installed on the second side, even if the number of fixed rails 11 is increased, it is not necessary to provide a corresponding number of stopper driving means, so that the structure can be simplified as a whole and the number of parts can be reduced. And cost can be reduced.

Although the connecting device of the present invention has been described based on the illustrated embodiment, the present invention is not limited to this, and the configuration of each part of the present invention can exhibit the same function. Any configuration can be used, and some of them can be omitted.

For example, the first stopper 2 and the second stopper 3 may have a structure having a stopper member which can move in the vertical direction to take the regulating position and the retracted position.

The fixing means may be provided independently of the stopper driving means. Also, the first rail and the second rail
Both rails may be movable rails (moving directions may be the same or different).

Further, the connecting device of the present invention can be installed in any location, for example, on a construction site, a construction site, a mining site, various factories, warehouses, ports for loading and unloading cargo, on a transportation route, and the like. It may be used in any place and for any purpose.
