Description

  The present invention relates to a transport mechanism, and more particularly to a transport mechanism that can efficiently transport a transported object such as a person or a vehicle between points having different heights or depths.

Under the roads of large cities, many tunnels and pipelines such as railways, electricity, gas, communications, and water and sewage are buried. For this reason, in a newly constructed subway or the like, it is necessary to avoid a pipeline that has already been constructed, and it is necessary to increase the depth year by year. For this reason, underground facilities, such as a subway, may be constructed in a deep underground part about 40 m deep (refer nonpatent literature 1). For example, when transporting a transported object such as a person or a vehicle between the ground and the underground facility, an escalator, an elevator, or the like is used in addition to the stairs.

However, when transporting using a normal elevator, one housing (transportation cabin) moves up and down to move the object to be transported from the deep underground to the ground or from the ground to the deep underground. For example, when there is a high demand for transportation from the ground to the deep underground, there is a problem that the transported object cannot be transported sufficiently and the transport efficiency is not good. In addition, when transporting with a normal escalator, the transport speed cannot be increased due to safety problems, and a large amount of transported objects cannot be transported at one time. There is a problem that the transfer efficiency is not good.

  Here, the operation of the rail switching device 50 will be described by taking as an example the case where the transport cabin 24 passes through the intersection S on the upper left side in FIG. As shown in FIG. 2, when the transport cabin 24 moves horizontally along the guide rail 32 in the left direction in FIG. 2, first, the front lower portion of the transport cabin 24 (the lower left side in FIG. 5). The first drive part 26X attached to the crossing part S of the guide rail 32 passes in the horizontal direction. Before the transport cabin 24 passes, the table unit 52 is rotated by the rotating unit control device 58 in the state shown in FIG. 7A, which is the initial position, that is, only the first guide rail 32X is connected ( First state). For this reason, the drive unit 26X on the front side passes through the intersection S of the guide rail 32 horizontally.

  Thereafter, the rotating unit control device 58 operates to rotate the table unit 52 so as to change the direction by 90 °, and the state shown in FIG. 7B, that is, the state where only the second guide rail 32Y is connected ( (Second state). Accordingly, the second drive unit 26Y on the upper rear side (upper right side in FIG. 5) of the transport cabin 24 passes through the intersecting portion S of the guide rail 32 in the vertical direction.

When the second drive unit 26Y of the transport cabin 24 passes through the intersection S, the rotating unit control device 58 operates to return to the initial state (first state) shown in FIG.
Note that this operation also operates in the same way for the lower right intersection T in FIG. 2 and the two intersections of the guide rail 32 disposed on the back side of the paper (not shown) due to space limitations.

  In the underground road access system 1 as described above, a case where the vehicle M accesses the ground road X from the underground road Y and a case where the vehicle M accesses the underground road Y from the ground road X will be described. As shown in FIG. 2, when the vehicle M stands by at the underground entrance 11 </ b> A, the carry-in detection sensor 28 stops the transport cabin 24 moving in a circulating manner at the underground entrance 11 </ b> A. When the vehicle M is not waiting at the underground entrance 11A, the carry-in cabin 24 passes through the underground entrance 11A by the carried-in detection sensor 28.

  When the transport cabin 24 stops at the underground entrance 11 </ b> A, the first confirmation sensor 25 </ b> R attached to the transport cabin 24 is activated to open the first door 24 </ b> R, and the vehicle M can enter the transport cabin 24. When the vehicle M is accommodated in the transport cabin 24, the first confirmation sensor 25R is actuated to close the first door 24R, the servo motor 40 is driven, and the pin rack 32A and the pinion 38 are engaged, whereby the transport cabin 24 is moved. It moves upward in the shaft 11 along the guide rail 32.

  When the transport cabin 24 comes in the vicinity of the ground exit 11B, the carry-out detection sensor 27 detects that the vehicle M is present in the transport cabin 24, so the transport cabin 24 stops at the ground exit 11B. When the vehicle M is not present in the transport cabin 24, the transport cabin 24 passes through the ground outlet 11 </ b> B by the carried-out detection sensor 27. When the transport cabin 24 stops at the ground exit 11B, the second confirmation sensor 25L is actuated to open the second door 24L on the exit side, and the vehicle M can exit the transport cabin 24. When the vehicle M leaves the transport cabin 24, the second confirmation sensor 25L is actuated to close the second door 24L on the exit side, and the transport cabin 24 that has become empty passes through the moving space below the roof portion 14. Move to the left in FIG.

  As described above, the transport cabin 24 that has moved to the left side in FIG. 2 has the table unit 52 of the rail switching device 50 after the first drive unit 26X on the front side passes through the intersection S of the guide rail 32 horizontally. Is rotated 90 °, and the second drive unit 26Y on the rear side passes through the intersection S of the guide rail 32 from the top to the bottom. Thereafter, the carry-in cabin 24 is stopped at the ground entrance 12A when the carried-in detection sensor 28 is operated, and the first confirmation sensor 25R is operated to open the first door 24R on the entrance side. The vehicle M that has traveled on the ground road X enters the transport cabin 24 from the ground entrance 12A, and after the first door 24R on the vehicle entrance side is closed, the transport cabin 24 moves downward in the shaft 12. . When the unloading object detection sensor 27 is activated and the transport cabin 24 is stopped at the underground outlet 12B, the second confirmation sensor 25L is activated to open the second door 24L on the vehicle outlet side, and the vehicle M exits the transport cabin 24. it can. After the vehicle M exits from the transport cabin 24 and the second door 24L on the exit side is closed, the empty transport cabin 24 moves to the right side in FIG.

Since only the access from the ground road X to the underground road Y is made possible by moving the transport cabin 24 downward, the transport cabin 24 is formed in a deep underground part compared to the case where the transport cabin 24 is moved up and down by one shaft. Access between the underground road Y and the ground road X formed in the ground part can be performed smoothly. That is, the vehicle M can be efficiently conveyed between the ground road X and the underground road Y.

  (2) Since the collision prevention sensor 24A is attached to the transport cabin 24, the transport cabins 24 can be driven intermittently without causing any collision between the transport cabins 24. For this reason, the transport cabin 24 can be arranged as efficiently as possible, and the transport efficiency of the vehicle M can be improved.

  (3) Since the transport cabin 24 is appropriately stopped or passed by the unloading object detection sensor 27 and the unloading object detection sensor 28 depending on the presence or absence of the unloading vehicle M, the vehicle M is more efficiently transported. be able to.

  (4) Since the transport cabin 24 is configured to be supported at two locations on each side, it is possible to reliably prevent the transport cabin 24 from swinging even if the vehicle M enters and exits the transport cabin 24. It is possible to increase the safety of transportation of the vehicle M.

  (5) By appropriately switching the rail 54 between the horizontal direction and the vertical direction by the rail switching device 50, the drive unit 26 can be reliably passed through the intersections S and T of the two guide rails 32.

  (6) Even when the underground road Y is provided in an urban area or the like, the underground road Y can be provided in the deep underground by the underground road access system 1, so it is necessary to use the site where the underground road Y is provided. Can be greatly reduced.
