Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a coupling release device for releasing a coupling of a trolley on a traverser as a transport facility used in an autoclave curing facility or the like.

<Prior art> For example, as a transportation equipment attached to autoclave curing equipment for curing concrete products such as ALC in an autoclave, rails for trolleys are laid inside multiple autoclaves arranged horizontally.
In front of the autoclave, a traverser with multiple rails arranged side by side for replacing carts is installed so that it can run in the transverse direction, and while the cart carrying the concrete products is running on these rails, the products are transported inside the autoclave together with the cart. Conveying equipment is used for loading and unloading.

<Problems to be solved by the invention> Some autoclaves used in this type of autoclave curing equipment are large enough to carry two or three carts at once; The length of an autoclave that can be transported is approximately 25 meters. In the transportation equipment for carts used in such large autoclave curing equipment, a traverser and a stockyard are required to pull out and place three connected carts from the autoclave, and the width of the traverser and stockyard is, for example, 25 m. Therefore, when pulling out a three-car connected truck from an autoclave, there was a need for equipment that would disconnect one car at a time, place each cart in parallel on a traverser, and transport them to a stockyard or the like.

The present invention has been made in view of the above points, and provides a device for uncoupling a bogie coupler, which can automatically and reliably uncouple and separate the bogies connected by the coupler at a predetermined location. This is what we provide.

<Means for solving the problem> The uncoupling device for a bogie coupler of the present invention is for disconnecting a coupler for a bogie placed on a rail on a traverser. A movable hook is rotatably supported in the vertical direction, and a disconnection member for rotating the end of the movable hook downward to release the connection is rotatably supported. An operating rod for rotating the traverser is linked to a disconnection member so that it can swing approximately horizontally, and a rail bridge is provided at the end of the rail on the traverser to bridge with other rails. A decoupling drive section having an actuating arm and a hydraulic cylinder for engaging the actuating rod and moving the actuating rod in a substantially horizontal direction is disposed therein.

<Operation> This uncoupling device operates when a bogie connected to the traverser from another passes through the rail bridge and stops at a fixed position. The rod swings, which causes the uncoupling member to rotate the movable hook, and the movable hook operates to disconnect from the hook of another truck.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a front view of a traverser 1 in an autoclave curing facility. The autoclave 2 is constituted by a cylindrical container having a length and an inner diameter such that, for example, three connected trolleys 3 can be carried in at one time, and a plurality of autoclaves 2 are arranged horizontally in parallel facing the same direction. These autoclaves 2
Inside, rails 4 for the bogie are laid out.

The ground in front of the autoclave 2 is dug horizontally, and a traverser rail 5 is installed in this dug part.

Further, although not shown, a stockyard is provided on the right side of the traverser 1 in FIG. 1, that is, in front of the autoclave 2 via the traverser 1, and a stockyard is provided in which a stacker crane moves, and rails for a truck are also laid.

The traverser is a transport device that sequentially carries the carts 3 in the stockyard into each autoclave 2, pulls out the carts 3 in the autoclave 2 one by one, and sends them out to the stockyard again. 4
At least three pairs of rails 6 are installed at the same height as the rails above the stockyard. The length of these rails 6 is sufficient if it is long enough to place one truck 3, and for this reason, the width of the traverser 1 can also be shortened to about the length of the truck 3.

There is an interval of about 1 m between the left end of the rail 6 on the traverser 1 in FIG. 1 and the right end of the rail 4 in the autoclave 2, and a rail bridge 7, which will be described later, is installed at the left end of the traverser 1 as a bridging member between them. Furthermore, the traverser 1 includes each pair of rails 6.
An elongated pusher 8 is movably disposed along the central longitudinal direction of the pusher 8, and an engaging claw 8a protruding from the upper left end of the pusher 8 is engaged with an engaging portion at the bottom of the truck 3, so that the pusher 8 Move 3. The pusher 8 is connected to the end of a chain 11 that extends between sprockets 9 and 10, and

In FIG. 1, 12 is a wheel of the traverser 1, 13 is a gear for driving the vehicle, and 14 is a rack disposed below the traverser 1 along the rail 5, with which the gear meshes.

FIG. 2 shows an enlarged view of the rail bridge 7, and FIG. 3 shows its plan view. The rail bridge 7 includes bridge parts 17 on both sides that bridge the two rails 4 and 6, and a rotating base 19 that fixes the bridge parts 17 to the tip and is rotatably supported by a rotating shaft 18. , the rotation axis 18 is the traverser 1
is supported via a bearing 20 at the left end. Rotation axis 1
A crank arm 21 is pivotally attached to the end of the crank arm 8, and a hydraulic cylinder 22 is attached to the tip of the crank arm 21.
A piston rod is connected to the hydraulic cylinder 22.
As a result of the pulling back operation, the rotation shaft 18 rotates, and the rail bridge 7 rises to a substantially vertical position. The left end of the rail 6 on the traverser 1 is formed in the shape of a circular arc centered on the rotation axis 18, and the left end of the rail 6 on the traverser 1
The right end portion of the rail 7 is also formed in a similar arc shape, and the gap between the bridge portion 17 and the rail 6 is reduced to enable rotation. Also, rail 4 on the autoclave side
The connecting portion of the bridge portion 17 and the bridge portion 17 have a structure in which the tip portions formed at an acute angle are brought together and connected.

A rail bridge 7 having such a structure is provided on the traverser 1 at the left end of each pair of rails 6 installed on the traverser 1, and when the traverser 1 reaches a predetermined position where the rails 6 and 4 are aligned in a straight line. When stopped, the rail bridge 7 moves horizontally from the vertical position and passes the document between the rails 4,6.

On the other hand, the first truck 3 moving on the rails 4 and 6
A hook 31 as a connecting tool is fixed upward at the left end of the figure, and a movable hook 32 is located at a position corresponding to the hook 31 at the right end of the trolley 3 and can rotate vertically within a certain angle range and downward. The movable hook 32 and the hook 31 of another truck can be engaged with each other. Note that a roller may be provided at the engaging portion of the hook 31 to facilitate engagement or release. As shown in FIGS. 4 and 5, a bracket 33 is installed approximately in the center of the left end of the truck 3.
is fixed, and a movable hook 32 is attached to the tip of this bracket 33 via a shaft 34. 35 is a stopper pin that restricts the downward rotation of the movable hook 32 in the horizontal position; 36 is a stopper pin that restricts the upward rotation of the movable hook 32 in the vertical position;
Fixed within 3. Therefore, the movable hook 32 is
Normally, as shown in Fig. 1, it takes a downward horizontal position, slightly collides with the hook 3 of another trolley 3, rotates slightly upward, returns to the engaged position, that is, the horizontal position under its own weight, and returns to the connected state. Become.

Reference numeral 37 denotes a disconnecting member which is rotatably supported in the bracket 33 by a shaft 38, and is provided with a roller section at the upper part, and is rotated by this roller section so as to push the end of the movable hook 32 downward. to rotate the movable hook 32 upward and release the connection. As shown in FIG. 5, a shaft 38 supporting the disconnection member 37 extends horizontally, and its end is supported by another bracket 39. 40 is trolley 3
The rear part of the operating rod 40 is swingably supported by the bottom plate of the truck 3 via a link 41, and the front part is connected to the shaft 38 in the bracket 39 via a link 42. Supported in a swingable manner. Therefore, when the operating rod 40, which is horizontally and swingably attached to the bottom of the truck 3, moves to the right as shown in FIG. 6, the shaft 38 rotates counterclockwise in FIG. The uncoupling member 37 rotates in the same direction about the shaft 38 and pushes down the end of the movable hook 32. The operating rod 40 has a space in its middle portion into which a rotating arm, which will be described later, can enter, and a roller 40a is pivotally supported in the space.

On the other hand, the above-mentioned rail bridge 7 has the following features as shown in FIG.
As shown in FIG. 4, a connection release drive section 23 is installed which moves the operating rod 40 to the right to release the connection. This uncoupling drive unit 23 has an operating arm 26 and a hydraulic cylinder 27, and the operating arm 26 is fixed to one end of a shaft 25 attached to the lower part of the rail bridge 7 via a bearing 24 so as to face upward. A piston rod of a hydraulic cylinder 27 is connected to the other end of the shaft 25 via a crank arm 28, and the operating arm 26 is connected to the hydraulic cylinder 27.
Rotates within a certain range around the center directly above. Further, the operating arm 26 is installed inside the bridge portion 17 at a position corresponding to directly below the operating rod 40 attached to the bottom of the truck 3, and normally tilts to the left as shown in FIG. 4 by the pushing operation of the hydraulic cylinder 27. When the carriage 3 reaches the position of the rail bridge 7 and the operating rod 40 reaches directly above the operating arm 26, the operating arm 26 can enter into the operating rod 40. Then, as the hydraulic cylinder 27 pulls back, the actuating arm 26 rotates clockwise in FIG. 4 and hits the roller 40a in the upper actuating rod 40, causing the actuating rod 40 to move rightward as shown in FIG.

Next, while explaining the movement of the traverser 1 in the autoclave curing facility, the operation of the truck coupling disconnection device will be explained.

Concrete products such as ALC to be cured are loaded onto trolley 3 by a stacker crane at the stockyard on the left side of Figure 1. Trolley 3 loaded with products
advances to traverser 1. A large number of rails 6 are laid in parallel on the traverser 1, and a cart 6 is placed on each of these rails 6. At this time, the rail bridge 7 is in a vertical position due to the retraction operation of the hydraulic cylinder 22, and the rail is in an open state.

In this state, the traverser 1 advances forward and backward to the position of the autoclave 2 into which the trolley 3 is to be carried, and
It stops at a predetermined position where the axes of rails 6 and 4 coincide. Next, the hydraulic cylinder 2 of the rail bridge 7
2 performs the extrusion operation, the bridge part 17 rotates to the horizontal position, and the rail 4 on the autoclave 2 side
and the rail 6 on the traverser 1 side to connect both rails. Note that at this time, the hydraulic cylinder 27 of the disconnection drive section 23 is in the pushing state, and the operating arm 26 is tilted.

In this state, the engaging claw 8a of the pusher 8 of the traverser 1 protrudes upward and engages with the engaging portion on the bottom of the trolley 3, and then the pusher 8 moves to the left in FIG. The carriage 3 moves in a pushing manner, whereby the carriage 3 crosses the rail bridge 7 from the rail 6 on the traverser and enters the autoclave 2.

Next, after returning the pusher 8 to its original position and opening the rail bridge 7 to a vertical state, the traverser 1 moves further to move the next cart 3 in front of the autoclave 2 into which it is to be carried. Then, in the same way as above, after the rail bridge 7 is rotated to the horizontal position and the connection between the rails 4 and 6 is established,
Pusher 8 operates and transports trolley 3 to autoclave 2.
Push it inside. At this time, the autoclave 2 has a length that allows three carts 3 to be inserted, and one cart 3 has already been inserted, so the cart 3 that will enter later
collides lightly with the front truck 3, and the movable hook 32 of the connector engages with the opposing hook 31, resulting in a connected state. In this way, three carts 3 are placed into the autoclave 2.

Completed loading the trolley into autoclave 2,
With the opening of autoclave 2 closed,
Its interior is heated under pressure using pressurized steam to cure concrete products.

When the autoclave 2 is opened after curing, the traverser 1 moves to position the empty rail 6 in front of the autoclave 2. Then, the traverser 1 stops at a position where the axes of the rails 4 and 6 coincide as in the case of carrying it in, and the rail bridge 7 bridges the rails 4 and 6 by the pushing operation of the hydraulic cylinder 22.

In this state, the pusher 8 on the traverser 1 moves leftward in FIG. . Then, Pushya 8 retreats back to above Traversa 1,
As a result, the leading truck 3 is moved above the traverser 1 while still connected, and as shown in FIG. When this happens, stop the trolley. When the hydraulic cylinder 27 of the connection release drive section 23 is pulled back, the operating arm 26 rotates clockwise as shown in FIG.
It hits the roller 40a of the operating rod 40, and the operating arm 2
6 moves the operating rod 40 to the right in FIG. As a result, the connection release member 37 is rotated counterclockwise about the shaft 38, and the movable hook 32 is rotated in the opening direction. Then, the movable hook 32 and the lower hook 31 are disengaged, and the connection of the connector is released.

Then, the hydraulic cylinder 2 of the connection release drive unit 23
7 returns to the pushing operation state again, and the operating arm 2
While 6 returns to the tilted state, Pushya 8 moves onto the trolley 3.
to the right in Figure 6. The leading cart 3 is now separated from the cart 3 in the autoclave 2 and placed at a fixed position on the traverser 1. Then, as shown in FIG. 1, the rail bridge 7 stands up again and opens, and the traverser 1 moves back and forth so as to position the empty rail 6 in front of the autoclave 2 that is being unloaded. And again as above,
With the axes of rails 4 and 6 aligned, the rail bridge 7 is brought down, and the pusher 8 is placed in the autoclave 2.
The carriage 3 in the autoclave 2 is pulled out across the rail bridge 7 to a fixed position on the traverser 1. If the next truck is connected after this truck 3, the actuating arm 26 rotates and the actuating rod 40 swings, thereby actuating the uncoupling member 37, allowing the coupling to move. The hook 32 rotates and the connection is released,
In this state, the pusher 8 is operated and the cart 3 is correctly placed on the fixed position of the rail 6 on the traverser 1.
Then, the third cart inside the autoclave 2 is also pulled out onto the empty rail 6 of the traverser 1 in the same way as above, and each cart 3 placed on the traverser 1 is then transferred to the stockyard. The products will then be transshipped.

<Effects of the Invention> As explained above, according to the uncoupling device for a bogie coupler of the present invention, a movable hook is rotatably supported in the vertical direction as a coupler at one end of the bogie, and the end of the movable hook An uncoupling member for rotating the uncoupling member downward is pivotably supported, and an operating rod for rotating the uncoupling member is linked to the uncoupling member at the bottom of the truck. A rail bridge is provided at the end of the rail on the traverser to be able to swing horizontally, and which bridges with other rails.A rail bridge is provided in the rail bridge to engage with the operating rod to move the operating rod in a substantially horizontal direction. Since the disconnection drive section has an actuation arm and a hydraulic cylinder for Even if the movable hook is connected to the rail, the connected state can be reliably and safely released from the rail side. For this reason, for example, when pulling out a plurality of connected carts from an autoclave, each time one cart is pulled out onto the rail on the traverser, the connection of the movable hook, that is, the coupling device is released by the operation of the connection release drive section. As a result, it is possible to separate multiple connected trolleys one by one, move the traverser, and efficiently place these trolleys on the multiple rails on the traverser, making it easier to transport the trolleys. The space for the traverser that carries out the unloading can be minimized.
