生し、この強制気流の圧力により荷物運搬台車を管路内

内運搬装置に関する。[Detailed Description of the Invention] The present invention generates forced airflow in a pipe installed on a transportation route, and uses the pressure of this forced airflow to propel a load carrying cart along the pipe to carry out forced transportation. This invention relates to an intra-pipe transport device that utilizes air flow pressure.

かかる強制気流圧利用の管路内運搬装置による運搬効率
の向上を図る手段としては、強制気流による台車推進が
可能な範囲内で可及的に台車の荷物積載量を多くし、以
って、一回の台車推進による荷物運搬量を多くする手段
がある。As a means of improving the transport efficiency of such an intra-pipe transport device that utilizes forced air pressure, the loading capacity of the trolley is increased as much as possible within the range that allows the trolley to be propelled by forced air flow. There is a way to increase the amount of cargo carried by one cart propulsion.

しかし、台車の前後方向長さを長く（台車の径は管路の
径により制約を受けるので、管路径を変えることなく台
車径を大きくすることはできない。However, it is not possible to increase the length of the truck in the longitudinal direction (since the diameter of the truck is limited by the diameter of the conduit, it is not possible to increase the diameter of the truck without changing the diameter of the conduit.

）し、以って、台車一台当りでの台車荷物載置部の積載
量を多くする手段では、台車全長が非常に長い故に、管
路の彎曲部分の最大曲率が全長の短かい台車を用いる場
合に比較して、非常に小さくなり、つまり、管路の彎曲
部分の彎曲半径を余り小さくできなく、管路構成に制約
を与える。) Therefore, as a means of increasing the loading capacity of the cargo loading section of a trolley per trolley, since the overall length of the trolley is very long, the maximum curvature of the curved part of the conduit means that the maximum curvature of the curved part of the conduit is In other words, the radius of curvature of the curved portion of the conduit cannot be made very small, which places restrictions on the configuration of the conduit.

このことは、設備全体の配置構或に制約を与えるととも
に、コストアップを招来する欠点がある。This has the disadvantage that it imposes restrictions on the layout of the entire equipment and also increases costs.

このため、今まで通りの台車の複数個をユニバーサルジ
ョイントを介して列状に連結して、これら列状台車を一
台の長尺台車として推進させる手段が開発されるに至っ
ている。For this reason, a method has been developed in which a plurality of conventional carts are connected in a row via a universal joint and the rows of carts are propelled as one long cart.

この場合、各台車の夫々に対して、その前後に強制気流
の圧力を受けるための受圧用円板を装備させると、各受
圧用円板による気流圧の総和が大きくなり、強力な推進
力を得られる利点を有する反面、全長が長い台車を用い
る場合に比較して構成部材数が多くなり、コストが高く
付くことはもちろん、重量が重くなる欠点があった。In this case, if each truck is equipped with pressure receiving discs to receive the pressure of the forced airflow before and after it, the sum of the airflow pressures from each pressure receiving disc will increase, creating a strong propulsive force. Although this method has the advantages, it has the disadvantage that the number of components is increased compared to the case where a truck with a longer overall length is used, and the cost is high and the weight is heavy.

このことは、全長が同じであっても、長尺台車に比較し
７てその積載率が非常に悪いのである。This means that even if the overall length is the same, the loading efficiency is much lower than that of a long truck.

これに鑑み、列状台車群のうち、移動方向の前後両端部
に位置するもののみを、気流圧受圧用円板を有する技術
が開発されるに至っている。In view of this, a technique has been developed in which only those located at both the front and rear ends in the moving direction of a group of lined bogies have airflow pressure receiving discs.

この開発技術手段を採用し一：列状台車を推進するにあ
たって、最も重要なことは、最後端部の台車がその気流
圧受圧｝４１円板で受ける気流の圧力により全体を推進
させる故に、管路内周面と最高端部台車の外周面との間
に、管路内の気流を後方から前方に通過移動させる様な
隙間があると、最後端部台車の愛ける推力が著しく低減
するので、最後端部台車の気流受圧性能を確実に発揮さ
せることである。Adopting this developed technology means, the most important thing when propelling a row of bogies is that the rearmost bogie propels the entire body by the pressure of the airflow received by its airflow pressure receiving pressure 41 disc. If there is a gap between the inner circumferential surface of the channel and the outer circumferential surface of the highest end bogie that allows the airflow in the conduit to pass from the rear to the front, the thrust of the rearmost bogie will be significantly reduced. , to ensure that the airflow pressure receiving performance of the rearmost truck is fully demonstrated.

しかし、前後の走行輪により管路内に両端支持状態にあ
る荷物載置部に荷物を積込む・と、その前後又は後方の
みに配置してある気流受圧用円板が、管路横断面に対し
て傾斜しようとする応力が作用する。However, when cargo is loaded onto the cargo loading section supported at both ends in the pipe by the front and rear running wheels, the airflow pressure receiving discs placed only in front and rear or behind the pipe are placed in the cross section of the pipe. A stress that tends to tilt acts against the surface.

それ故に、気流受圧用円板のみから気流受圧性能を確保
し７ようとする場合（従来手段）には、最後端部台車に
荷物を積載すると、たとえ、気流圧受圧用円板を無載荷
状態においては管路内周面との間に間隙を生じささない
様に精度良ぐ製作してあっても、その気流受圧用円板が
管路横断面に対して傾斜することにより、管路内気流の
後方から前方への通過移動を許す間隙を管路内周面との
間に形成する。Therefore, when trying to secure airflow pressure receiving performance from only the airflow pressure receiving disk (conventional means), if cargo is loaded on the rearmost cart, even if the airflow pressure receiving disk is left unloaded. Even if the airflow pressure-receiving disk is tilted with respect to the cross section of the pipe, even if it is manufactured with high precision so as not to create a gap between it and the inner peripheral surface of the pipe, the inside of the pipe may be damaged. A gap is formed between the inner circumferential surface of the pipe and the inner peripheral surface of the pipe to allow airflow to pass from the rear to the front.

その結果、従来では、最後端部台車に荷物を積載しない
状態又は、非常に積載量小なる状態で列状台車を推進さ
せていたのであるが、このことは、列状台車の前後全長
の割には、一回での荷物運搬量が少なくなるのである。As a result, in the past, the line-shaped carriages were propelled with no cargo loaded on the rearmost carriage, or with a very small loading capacity. This means that the amount of cargo transported at one time is reduced.

換言すると、特に最後端部台車を空台車として列状台車
を推進するときには、結果として、荷物積載に対して不
要な台車を一台連結して推進することになるので、列状
台車全長に対する運搬量比率が著しく低下するのである
。In other words, especially when propelling a line of carts with the rearmost cart as an empty cart, as a result, one unnecessary cart for loading cargo will be connected and propelled, so the transportation for the entire length of the line of carts will be reduced. The quantity ratio drops significantly.

The objective is to provide an intraductal conveying device with a suitable structure.

車の推力として有効に利用し得るに至ったのである。The characteristic structure of the intra-pipe transport device using forced air pressure according to the present invention is that a cargo transport cart equipped with running wheels on both front and rear sides of the cargo loading section is installed in the pipe, and the cart is attached to the pipe. In an intra-pipe transport device using forced air pressure, which is configured to be propelled by the pressure of the forced air flow generated in the pipe by attaching an air flow pressure receiving disk having a diameter smaller than the inner diameter of the pipe,
Elastically biasing the combination wheel outward in the radial direction of the pipe so as to make elastic contact with the inner circumferential surface of the pipe at a plurality of locations in the circumferential direction of the pipe,
In addition to providing a roller, the outer peripheral edge shape of the sealing member for controlling the movement of air flow in the axial direction of the pipe O is configured to be elastically deformable in the radial direction of the pipe, and further, the roller The rocking biasing mechanism of the roller and the attachment member of the seal member are interlocked and connected so that the shape of the outer peripheral edge of the seal member changes in response to a change in position in the radial direction of the pipe, and such a configuration is provided. It has the following effects:
, That is, the rollers that move elastically against the inner circumferential surface of the conduit detect the cross-sectional shape of the conduit. Since the shape of the outer periphery is deformed, the seal member can be mounted on a transport vehicle with the outer periphery of the seal member as close as possible to the inner circumferential surface of the pipe, and as a result, the seal member By suppressing as much as possible a large amount of airflow from leaking from the gap between the inner circumferential surface of the pipe and the inner peripheral surface of the pipe, the airflow pressure within the pipe can be effectively used as thrust for the transport vehicle.

成を得られ、運搬台車の推力を大きく低減させない点で
も有利である。Furthermore, since a roller that comes into elastic contact with the inner circumferential surface of the pipe is used as a means for changing the outer circumferential shape of the sealing member in response to a change in the cross-sectional shape of the pipe, the sealing member can be attached to the pipe. Compared to the case where the sealing material is pressed directly and elastically deformed, there is no resistance due to sliding friction between the sealing material and the inner circumferential surface of the pipe, and the above structure can be obtained by shifting the rollers with relatively little resistance. It is also advantageous in that it does not significantly reduce the thrust of the engine.
