Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a spiral escalator that ascends and descends in a spiral manner.

[Prior Art] In general, an escalator is formed in the shape of a staircase, and the treads are moved endlessly in a linearly inclined manner by means of an endless chain for driving.

[Problem to be solved by the invention] By the way, when such an escalator is adopted in a place with a large difference in height, the escalator's inclination angle is specified, so the distance becomes very long, and the installation space of the escalator is limited. It was necessary to make it larger.

Especially today, when deep underground transportation systems are being constructed,
Escalators are often used as a means of transportation for moving passengers up and down in large numbers. However, in order to employ the above-mentioned escalator in deep underground transportation, a large amount of underground excavation had to be performed to create a space for installing the escalator.

The present invention was devised to solve the above problems, and its purpose is to reduce the installation space of escalators, and to reduce the amount of underground excavation, especially when adopted for deep underground transportation. The purpose of the present invention is to provide a spiral escalator.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a plurality of treads arranged to form a spiral staircase, and a tread provided on both sides of the tread to guide these treads in a spiral manner. A guide rail formed in such a manner that the treads are connected to each other, a guide roller provided on both sides of each of the treadboards so as to be able to roll freely along the guide rails, and at least one end side of the treadboards are continuously connected to each other, and the treadboards are connected together. and an east end chain for transportation.

[Operation] Since the treads forming the escalator are configured to move up and down in a spiral manner, the distance traveled is shorter than that of a linearly inclined escalator. Moreover, since the foreign customer is formed into a substantially cylindrical shape, the space in which it is installed becomes small. Particularly when adopted for deep underground transportation, the installation space only needs to be a circular vertical space, so underground excavation is easy and the amount of underground excavation can be reduced.

[Example] An embodiment of the present invention will be described based on the drawings.

It is guided by the guide roller 23 rolling inside the guide roller 23 and the guide roller 24 rolling inside the guide rail member 30 of the roller kite rail 26, and is transported while forming a spiral staircase. During this transfer, each footboard 6 follows the endless chain 7 guided by the chain guide rail 12 in the vicinity of the elevator entrance 4.5, and changes its movement direction from a spiral curvature to a straight line or from a straight line to a spiral. The roller 10 and the guide roller 15.2 are changed into a curvature of
A spiral escalator is formed by changing the posture of each step board 6 from a step-like shape to a flat state, or from a flat state to a step-like state under the control of 3.24. Like this-
The endless chain 7 that has reached the E section elevator 4 is further guided by the chain guide rail 12 and exits the outer shell 3.
Furthermore, the movement direction is downward through some of the tin 1'2 get 19 "outside of the outer shell 3", and it descends almost perpendicularly and directly along the outer side of the outer shell 3, and the outer layer of the outer shell 3 It changes its direction of movement via the lower sprockets 20 and 21, enters the outer shell 3 from the bottom of the outer shell 3, and reaches the lower hatch 5 via the sprocket 22 near the lower hatch 5. , each step board 6 connected to this endless chain 7 is formed into a continuous loop.

In the above, as shown in FIGS. 2 and 3, when each tread 6 changes from a spiral curvature to a straight line or conversely from a straight line to a spiral in the vicinity of the entrances 4 and 5, it becomes a straight line. The upper surface of the tread 6, which is formed in the shape of The safety of the passage of passengers on the Esca I/-Evening train will be ensured.

In this way, since the spiral escalator of Honjitsu) [is formed in a spiral shape, the outer shell 3 is formed in a cylindrical shape, so that the space to accommodate it is can be small. In particular, when this is used for underground transportation, the amount of underground excavation required to form the accommodation space can be reduced.

Further, since the main components can be manufactured by housing them in the outer shell 3 at another location, the manufacturing is easy and the manufacturing cost can be reduced.

In the above embodiment, the endless chain 7 is provided only on one side of the tread plate 6, but the endless chain 7 may be provided on both sides of the tread plate 6. In that case, one side is the link member of the endless chain 7. A long hole may be provided in the connecting portion with the roller shaft 11 to loosely connect the roller shaft 11.

Further, although the spiral escalator is housed in the outer shell 3 formed into a cylindrical shape, the present invention is not limited to this, and instead of the outer shell 1 and the inner shell 2 forming the outer shell 3. Alternatively, a spiral escalator may be formed by making a plurality of pillars stand upright and fixedly supporting a guide rail or the like.

[Effects of the invention J The present invention exhibits the following effects.

Because the escalator is spiral-shaped, it requires less space to accommodate than a conventional escalator that has a straight slope.Especially when it is used for underground transportation, it requires less underground excavation. It is possible to reduce the manufacturing cost.
