Description

[Detailed description of the invention] This invention relates to an improvement of the bottom cover of a capsule vehicle for pipeline capsule transportation.

Pipeline capsule transportation, as is well known, is a method of transporting cargo by running a capsule train consisting of several container-type capsules on wheels through a pipeline using pneumatic pressure.

The capsule vehicle in this transportation system has an opening for loading cargo at the top and a bottom cover for unloading the cargo at the bottom, and the bottom cover can be opened horizontally or vertically.

For example, the conventional side-opening bottom lid, for example, has one end pivoted to the capsule body, and uses that pivot point as a fulcrum to open and close in the vertical direction, with both the left and right bottom lids hanging down when opened, and when closed. The bottom cover is closed by pushing it upwards, and then locked using a locking device provided on the bottom cover or the capsule body.

However, since the conventional locking mechanism is only pivoted to the capsule body using a so-called hinge, the locking mechanism must be able to withstand the load of the cargo inside the capsule as well as vibrations and rocking during travel. As a result, the locking mechanism has to be complicated, expensive, and time-consuming to repair.

In addition, when the baggage is sticky, there is a drawback that a considerable amount of the baggage sticks to the bottom lid.

This invention solves the above-mentioned conventional problems and provides a bottom cover that can always operate stably.

As shown in the drawings, this device consists of a bottom cover 4 having the same arc shape as the end plate 3 of the capsule body. It has a structure that supports the capsule so that it can be opened and closed left and right around pins P, P2, and the central part of the capsule body is attached to a suspension rod 6 that is pivotally connected to a partition plate 5 provided on the capsule body by a fulcrum pin P□. and suspend the bottom cover 4.

The lower part of the hanging rod 6 and the bottom cover 4 are overlapped with a connecting plate 7 protruding near the abutting surface of the bottom cover, and a connecting pin P3 is loosely passed through the connecting plate 7 and connected thereto.

On the other hand, both ends of the capsule body have hanging rods 6 similar to the central part.
The bottom cover 4 is suspended at the bottom cover 4, and is slidably suspended on a guide rail 9 fixed to the end plate 3 of the capsule body via a hanging tool 10 with a clamping roller.

Both ends of this bottom cover are suspended. The hanging rod 6 has its upper part rotatably attached to a fulcrum pin P2 which is protruded from the end plate 3 of the capsule body on the same center line as the fulcrum pin P1 in the central part, and has a connecting part which is protruded from the abutting part of the bottom cover. The lower part of the hanging rod is overlapped with 11, and the connecting pin P4 is loosely passed through and connected to that part.

Further, the guide rail 9 is provided concentrically with the bottom cover 4, and a stopper 12 of a hanging tool 10 with a clamping roller is provided at one end thereof.

The hanging tool 10 with clamping rollers has one end fixed to the bottom cover with a bolt or the like, and has three rollers R that clamp the guide rail 9 at the other end.

In addition, a scraper 13 for removing deposits on the inner surface of the bottom cover is provided in the gap between the capsule body 2 and the bottom cover 4 on the side wall of the capsule body, and both bottom covers 4 are suspended so that the scraper comes into sliding contact with the inner surface of the bottom cover. .

By providing the capsule in this manner, the contents will not become stuck between the capsule main body 2 and the bottom lid 4 due to the action of the scraper, and the opening and closing of the bottom lid will always be performed smoothly.

The scraper 13 may be omitted depending on the type of cargo.

On the other hand, as a method of locking the bottom cover, a curved plate 14 having a concentric arc with the bottom cover is integrally provided along the bottom cover at the lower end of the reinforcing plate 5 □ provided integrally with the partition plate 5 of the capsule body. A locking pin 15, which is always pushed upward by a spring 16, is attached to the bottom cover 4 at a position corresponding to the position directly below the curved plate so that it can freely appear and retract from the top surface of the curved plate. 14 to lock the bottom cover 4.

In addition, as a means for opening the locked bottom cover 4, this invention uses a pipeline bottom cover 1 disposed concentrically with the bottom cover 4.
8, a movable claw 19 is provided projecting to fit between the cam plate 17 and the bottom cover 4 when the pipeline bottom cover is opened, and the movable claw 19 pushes down the cam plate 17 against the spring 16. A mechanism is used in which the locking pin 15 is automatically released by sinking into the curved plate 14 provided at the lower part of the reinforcing plate 5□.

In this invention, the structure in which both the left and right bottom lids 4 are supported at two places, the central part and both side ends of the capsule body 2, is because the bottom lid has rigidity and one of the supporting parts, especially at both side ends. This is because consideration was given to prevent overload from being applied to the supporting parts.

In addition, the structure in which both ends of the bottom cover 4 are supported by the hanging rods 6 and hanging tools 10 is intended to support the bottom cover safely and securely and to prevent interference with various devices attached to the end plate 3 of the capsule body. This is to ensure that the free space on the end plate of the capsule body is as wide as possible.

Of course, the support mechanism for both ends may be provided solely by the hanging rod 6 or the hanging tool 10.

FIGS. 2 and 3 are explanatory diagrams of the opening and closing operations of this invention, with the left half of the figure showing the bottom cover 4 in a closed state, and the right half showing the bottom cover 4 in an open state.

That is, when opening the closed bottom cover 4, when the bottom cover 18 of the pipeline is opened, the movable claw 1 provided on the bottom cover
The locking pin 15 is connected to the spring 16 through the cam plate 17 of the locking pin 15 attached to the bottom cover 4 of the capsule vehicle 1 at the tip of the locking pin 15.
When the locking pin 15 is depressed by the curved plate 14 integrated with the partition plate 5, the lock is released and the pipeline bottom cover 18 is opened together with the pipeline bottom cover 18.

At this time, even if the stored items are attached to the inner surface of the capsule vehicle bottom cover 4, the scraper 13 attached to the capsule body
Due to this action, the deposits will not get stuck between the capsule body and the capsule body.

Therefore, the bottom cover 4 can be smoothly opened and closed.

When the open bottom cover 4 closes, the movable claw 19 separates from the cam plate 17 of the locking pin 15 because both bottom covers 4 close before the pipeline bottom cover 18, contrary to when the bottom cover 4 is opened. 16, the locking pin 15 automatically passes through the curved plate 14 and is locked.

In addition, as a method for opening and closing the bottom cover 4, in addition to using the pipeline bottom cover, it can be opened and closed using power from a cylinder or the like at the unloading area, for example.

As mentioned above, this design has a structure that opens and closes along the capsule body, and is supported at the center and both ends of the capsule body. It is superior in terms of both strength and opening/closing operation, and is economical because a simple locking mechanism as illustrated in the drawings is sufficient.
