Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to various coasters of amusement facilities installed in an amusement park and the like, and relates to a device for braking a track vehicle.

[Conventional technology]

2. Description of the Related Art Generally, an orbiting vehicle device of an amusement facility installed in an amusement park or the like is provided with a device for braking a vehicle. As a vehicle braking device of this type, there is provided a device configured to hold a braking plate projecting from a vehicle by a pair of brake warps installed on the track side, and apply a braking force to the braking plate by friction between the two. , For example, Jitsuko Sho 58-981
It is known from Japanese Patent No.

In the above-mentioned publication, a leaf spring that elastically presses these brake sledges always inward is provided on the outside of a pair of brake sledges that are arranged opposite to each other, and the above-mentioned brake sledges are always kept in a pressure contact state by these leaf springs. When the track vehicle travels to the position of the braking device, the braking plate protruding from the vehicle enters between the brake warps in the pressure contact state, and friction generated between the brake warp and the braking plate. It is designed to apply braking force with resistance.

Further, when the braking by the brake warp is released, the air spring device interposed between the brake warps is inflated, and the expansion of the air spring device causes the brake warp to resist the pressing force of the leaf spring. Are separated from each other, thereby releasing the braking plate from the clamping pressure of the brake sled.

In the braking device having such a configuration, since the pair of brake warps are constantly pressed by the leaf springs to form the normally closed structure,
When the vehicle comes in, the brake is automatically applied, which has the advantage of high safety.

That is, if, in addition to the above braking device, a pair of brake warps is configured to be closed by a closing drive means such as a cylinder, when the cylinder, the piping structure for applying fluid pressure to the cylinder, or the fluid pressure generating device fails, or suddenly. If a power failure occurs in the vehicle, braking will not work and the vehicle may run out of control.

On the other hand, the braking device disclosed in the above publication has a normally closed structure in which the pair of brake warps are constantly elastically pressed by the leaf springs, and therefore, such a problem does not occur and the safety is high.

By the way, this type of braking device may be installed at a high place, and therefore, there is a tendency for downsizing and weight reduction of the braking device.

[Problems to be solved by the device]

When releasing the braking, the braking device disclosed in the above publication has a structure in which compressed air is supplied to an air bag installed between a pair of brake slings to inflate the air bag. There is a drawback that it takes time.

Further, generally, in this type of braking device, when braking, a force along the tangential direction, that is, the approaching direction of the vehicle is applied to the brake sled, and the brake sled tends to move in this direction. In order to prevent this, the braking device described in the above publication adopts a structure in which slide shafts are fixed to the rear surface of each brake sled and the slide shafts are held slidably by bearings.

However, in such a conventional structure, since the slide shaft largely projects from the rear surface of the brake warp, the device becomes large in size, and since the slide shaft and a plurality of bearings are required, the weight becomes large and the number of parts is increased. It also has the drawback of increasing.

Therefore, it is an object of the present invention to reduce the size and weight of the structure for pressing a pair of brake sledges toward each other, simplify the structure for releasing the braking, and further apply the tangential force to the brake sledge. It is an object of the present invention to provide a braking device for a tracked vehicle that has a simple structure that prevents the vehicle from moving due to the movement, and that can reduce the size and weight of the entire structure.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is arranged on the outside of both brake sledges, and an elastic member that constantly presses these brake sledges toward the inside, and an elastic member that is arranged on the outside of these elastic members and holds these elastic members. The cradle and the pair of brake sledges and the fixed portion on the track side are rotatably connected to each other, and the brake sledges are prevented from moving in response to a tangential force applied to the brake sledges during braking. A brake warp retaining link for blocking, a pair of brake release link levers whose upper ends are rotatably suspended by the pair of brake sledges, respectively, and which are rotatably supported in the middle in the middle,
It is hung between the lower ends of these brake release link levers,
And a brake releasing cylinder for separating the pair of brake warps from each other against the pressing of the elastic member.

[Action]

According to the above configuration, the structure for releasing the braking is composed of a pair of braking release link levers rotatably suspended by the brake sled and pivotally supported mutually in the middle, and a pair of these braking release link levers. The structure is simplified because it is composed of a brake releasing cylinder that is bridged between the lower ends. Also,
Since the brake warp retaining means is composed of a retaining link extending between these brake warps and the fixed portion on the track side, this also has a simple structure.

When the brake sled is connected to the fixed member on the track side by the retaining link, when the braking sled approaches and separates from each other, the braking sled moves in the contact and separation directions with the retaining link as a radius and also in the tangential direction. It must be allowed to move slightly. In response to such movement of the brake sled, in the case of the present invention, a pair of brake release link levers and brake release cylinders for releasing the braking are installed by being suspended from the brake sled.
It moves following the brake warp with respect to the movement of the brake warp in the contact and separation direction and a slight tangential direction, so that it does not hinder the movement of the brake warp and acts on the brake warp at a predetermined position to separate these brake warps. Can be made.

[Example of device]

The present invention will be described below based on an embodiment shown in the drawings.

In FIG. 2, reference numeral 1 denotes a track running vehicle such as a coaster, which runs on a pair of track rails 2 and 2 which are separated from each other. Wheels 3, 3 and 4, 4 rollingly contacting the track rails 2, 2 are attached to the track vehicle 1, and a braking plate 5 is provided in a suspended state on the lower surface of the central portion.

A braking device according to the present invention is installed between the track rails 2 and 2.

That is, 10 are located below the track rails 2 and 2 and are installed in a direction orthogonal to the track rails 2 and 2, and as shown in FIG. The fixed pedestals 10 and 11 are fixedly provided with two pairs of left and right support pedestals 11 ...

Receiving bases 12 ... Are mounted on the support bases 11 ... so that the positions thereof can be adjusted inward and outward by bolts 13 ... and elongated holes, and the bolts 13 ...
Are fixed to the support bases 11 ... Support base 11
Brackets 14 ... Are projectingly provided on the top of the brackets. Adjusting bolts 16 ... Fixed by lock nuts 15 ... are screwed into the brackets 14 ... These adjusting bolts 16 ... Abut on the outer surface of the pedestal 12 ..., and push the pedestal 12 ... so as not to move outward.

A guide protrusion 17 extending horizontally inward is formed on the inner surface of the pedestal 12, and a buffer rubber 18 corresponding to the elastic member of the present invention is formed at the center of the inner surface of the pedestal 12.
Is attached.

Numerals 20 and 20 are brake sledges, which are formed of a rigid metal body that extends long along the track rails 2 and 2. Brake shoes 21, 21 are stretched over the entire inner surfaces of the brake sledges 20, 20, and the front surfaces of the cushioning rubbers 18 ... Abut on the outer surfaces of the brake sledges 20, 20. Therefore, each of these brake slings 20, 20 is always pressed and urged inward by the buffer rubbers 18 to keep their natural thickness. This allows a pair of left and right brake sleds 2
0 and 20 are pressed so that they can be separated from each other so as to approach or contact each other.

The lower surfaces of the brake sleds 20, 20 are slidably guided by slide plates 22 ... Attached to the upper surfaces of the fixed mounts 10. Further, on the outer surfaces of the brake slings 20, 20, there are provided projecting protrusions 23 ... that are projected in the horizontal direction and guided by the guide protrusions 17 of the pedestal 12 ... By these guide protrusions 17 and 23. The inclinations of the brake warps 20 and 20 are prevented from exceeding a predetermined amount.

The brake sleds 20 and 20 are formed in taper 24 and 24 which the front end of the approach side of the vehicle 1 opens outward, and these taper parts 24 and 24 guide the braking plate 5 between the brake sleds 20 and 20.

Each brake sled 20, 20 is provided with a braking release mechanism for separating the brake sleds 20, 20 against the pressure of the cushioning rubbers 18 ...

That is, brackets 25, 25 are welded to the outer surface at the center position in the longitudinal direction of each brake sled 20, 20 as shown in FIG.
The upper ends of brake release link levers 27, 27 are rotatably connected via 26, 26. The brake release link levers 27, 27 are pivotally connected to each other in the middle by a pivot 28, and the brake release link levers 27, 27 are connected.
A brake releasing air cylinder 30 is installed at the lower end of the brake via support pins 29, 29. In this case, the pivot 28 that pivotally supports the braking release link levers 27, 27 has the fixed mount 10 ...
The brake release link levers 27, 27, the pivot 28, and the brake release air cylinder 30 are not connected to the brake supports 20 and 20 at all.

When the brake releasing air cylinder 30 is extended, the brake releasing link levers 27, 27 are rotated, so that the brake sleds 20, 20 are separated from each other against the pressure of the cushioning rubbers 18. It is designed to be used.

A brake warp retaining mechanism is provided at the front ends of the brake warps 20, 20 where the vehicle 1 enters. That is, a fixed base 31 is welded to the fixed base 10 as shown in FIG.
The front ends of the brake warp retaining links 33, 33 are rotatably connected via 32. Brake sled retaining link 3
The rear ends of 3, 33 are rotatably connected to the front ends of the brake sleds 20, 20 by other supporting shafts 34, 34.

Therefore, when the brake sledges 20 and 20 try to move in the arrow A direction, the retaining links 33 and 33 pull the brake sledges 20 and 20 and prevent the movement in the arrow A direction.

Reference numeral 35 is a sensor such as a limit switch that is actuated by one of the brake slings 20 when the brake sleds 20 and 20 are opened. The signal of the sensor 35 controls the entry of the following vehicle 1 and the like. .

The operation of the braking device in the embodiment thus configured will be described.

When the brake releasing air cylinder 30 is in the shortened state, the brake sledges 20, 20 are pushed inward by the cushioning rubber 18, so that the brake shoes 21, 21 are in contact with each other with an appropriate pressure contact force. That is, the brake sleds 20 and 20 are kept in the closed state.

In this state, when the track-traveling vehicle 1 travels at a certain speed in the direction of arrow A in FIG. 1, the braking plate 5 hung down on the track-traveling vehicle 1 is placed between the brake sleds 20 and 20, and Push 20 and 20 open to enter.

The brake sleds 20, 20 pushed open by the braking plate 5 are displaced outward by the guiding action of the slide plate 22 and the guide protrusions 17, ..., 23, thereby bending the cushioning rubber 18. Therefore, the cushioning rubbers 18 ... Try to push the brake warps 20, 20 inward by the restoring force, and press the braking plate 5.

Since the braking plate 5 is in sliding contact with the brake shoes 21, 21 attached to the inner surface of the brake sleds 20, 20 and is pressed by the brake sleds 20, 20 to which elastic force is applied from the cushion rubber 18, ... The traveling of the vehicle 1 is stopped by the sliding frictional resistance.

Therefore, when the vehicle 1 is braked, the brake sled
A force in the vehicle traveling direction (direction of arrow A) due to the sliding frictional resistance, that is, a tangential force is applied to 20, 20. However, since the front ends of the brake sledges 20 and 20 are connected to the fixed base 31 via the retaining links 33 and 33, the brake sleighs 20 and 20 are prevented from moving in the tangential direction. For this reason, the brake sleds 20 and 20 reliably clamp the braking plate 5 and exert a high braking force. The reason why the link mechanism is adopted by using the links 33, 33 as the retaining means is that the movements of the brake sledges 20, 20 inward and outward are not restricted.

When the brake sill 20, 20 is pushed open by the brake plate 5, one brake sledge 20 pushes the sensor 35 to activate it. As a result, it is detected that the vehicle 1 is stopped by the braking device, and, for example, the following vehicle 1 is detected.
Can be used to operate another braking device installed in front so that the vehicle does not enter the braking device.

When it is desired to change the braking force of the brake sledges 20, 20 on the braking plate 5, the adjustment bolts 16 ... Are screwed back and forth to adjust the positions of the pedestals 12 ...
Since the set load of ... changes, the braking force can be adjusted.

Next, a case where the braking is released will be described.

When the brake releasing air cylinder 30 is extended, the brake releasing link levers 27 are rotated about the pivot 28 in the directions of arrows B and B in FIG. For this reason, the brake sled connected to the upper ends of the brake release link levers 27, 27.
20 and 20 are moved in the directions of arrows C and C. That is,
The brake sleds 20, 20 are forcibly opened against the pressing force of the buffer rubber 18.

Therefore, the clamping pressure of the brake slings 20, 20 on the braking plate 5 is released and the braking plate 5 is opened, so that the vehicle 1 can start traveling.

When the vehicle 1 whose braking is released by the brake releasing air cylinder 30 and the brake releasing link levers 27, 27 passes between the brake sleds 20, 20, the brake releasing air cylinder 30 is shortened and returned. This allows the brake sled 20, 20
Receives the pressing force of the cushioning rubber 18 and again approaches and abuts again, becoming a so-called closed state and entering the vehicle 1 next time.
Prepare for

According to the braking device having such a configuration, the brake sled 20,
Since the cushioning rubber 18 is used as the elastic member that presses the spring 20, it is lighter and smaller than the leaf spring and the coil leaf spring, but can exert a pressing force equivalent to those of the leaf spring and the coil spring. Moreover, since the cushioning rubbers 18 can be attached to the brake slings 20 and 20 and the pedestals 12 and 12 with an adhesive, no special attachment tool is required.

Further, the detent links 33, 33 prevent the brake warps 20, 20 from moving in the traveling direction of the vehicle, that is, in the tangential direction, so that reliable braking can be performed. Moreover, since the detent links 33, 33 can be installed on the longitudinal extension of the brake slings 20, 20, they do not extend in the width direction of the tracks 2, 2 and the entire braking device has a special space in the width direction. It becomes small and unnecessary.

Since the retaining links 33, 33 are connected to the fixed base 31 and the brake sleds 20, 20 by the support shafts 32, 32 and 34, 34, respectively, the number of parts is small and the weight is reduced. To be done.

On the other hand, since the brake release link levers 27, 27, the pivot 28 and the brake release air cylinder 30 are suspended by the brake sleds 20, 20, they can move integrally with the brake sleds 20, 20. That is, when the brake sledges 20 and 20 are brought into contact with and separated from each other, the brake sledges 20 and 20 are displaced in the front and rear and left and right directions because they are restrained by the retaining links 33 and 33. 27, the pivot 28, and the air cylinder 30 for releasing the brake are also these brake slings 20, 20.
Fluctuates with. Therefore, the brake release link lever
27, 27 can surely act the separating force of the predetermined position of the brake sledges 20, 20 and do not give the brake sledges 20, 20 an inclination.

Then, the brake release link levers 27, 27 are brake sleds.
When the brake release link levers 27, 27 rotate about the pivot 28, the upper ends of the brake release link levers 27, 27 have the brake sleds 20, 20 because they have a structure suspended by 20, 20. It moves horizontally with the
And the brake releasing air cylinder 30 is vertically displaced.
That is, the pivot 28 is not connected to the fixed frame 10 ..., the support 11 ..., etc. at all, and therefore, the brake release link lever is used.
27, 27, the pivot 28, and the brake releasing air cylinder 30 are suspended by the brake slings 20 and 20 and can move freely in the vertical direction. Therefore, the brake releasing link lever 27 is moved based on the expansion and contraction operation of the brake releasing air cylinder 30. The upper end of 27 can be moved horizontally. As a result, the brake sled 20,
Only horizontal force can be transmitted to 20.

On the other hand, for example, the pivot 28 is fixed to the mount 10 ...
.. and the like, the braking release link levers 27, 27 will rotate about the fixed pivot 28,
The upper ends of the brake release link levers 27, 27 make an arc motion. Such an arc motion causes a deviation with respect to the brake sledges 20 and 20 desiring to move in the horizontal direction, which causes a problem that the brake sledges 20 and 20 are tilted. Therefore, the support pin is absorbed to absorb the deviation difference. If a structure such as connecting the 26, 26 with a long hole is adopted, rattling occurs, which causes a problem that the force cannot be reliably transmitted to the brake sleds 20, 20.

Further, by suspending the brake release link levers 27, 27, the pivot 28 and the brake release air cylinder 30 on the brake sleds 20, 20, the number of parts is small and the configuration is simple, and the brake installed especially at a high place. For equipment, brake sled 20, 20
The space below can be effectively used, and no special space is required.

Because of this, it is possible to reduce the weight and size of the entire braking device.

In the above embodiment, the brake releasing air cylinder 30 is
Although the case where it is used so as to extend when braking is released has been described, if an emergency occurs and you want to use sudden braking, operate this air cylinder 30 further shorter than the normal state, It is also possible to increase the clamping pressure of the brake slings 20 and 20 to increase the braking force applied to the braking plate 5.

Further, when the brake sledges 20 and 20 are configured to be long, the number of rubber members and the braking release mechanism may be increased if necessary.

Further, the brake sledges 20 may be provided with a plurality of pairs which are paired with each other on both sides of the track along the direction of the track.

[Effect of device]

As described above, according to the present invention, a structure for releasing braking is provided with a pair of brake releasing link levers that are rotatably suspended by a brake sled and axially rotatably supported with respect to each other, and these brake releasing links. Since it is composed of the brake releasing cylinder that is bridged between the lower ends of the brake link levers, the operation timings of both brake warps coincide, the number of parts is reduced, and the structure is simplified. Further, the brake warp retaining means is composed of a retaining link which is bridged between the brake warp and the fixed portion on the track side, and therefore the structure is also simple.

In addition, when the brake sled is connected to the fixing member on the track side by the retaining link, when the braking sleds approach and separate from each other, the braking sled moves in the contact and separation directions with the retaining link as the radius, and in the tangential direction. However, since a pair of brake release link levers for releasing the brake and the brake release cylinder are suspended on the brake sled, these brake release members are not connected to the brake sled. It moves following the brake sled with respect to the separation direction and a slight tangential direction movement, so that it does not hinder the movement of the brake sled and the point of action of the force that separates the brake sled does not change, and the brake sled is tilted. It is possible to reliably apply a force for separating these brake warps to a predetermined position of the brake warps without causing them. Therefore, the vehicle can be reliably braked.

Moreover, this can effectively utilize the space below the brake sled, and can reduce the size and weight of the entire braking device with a simple structure.
