Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water surface floating type transportation path utilizing buoyancy which can be applied to a transportation path for moving an airplane from a runway to a hangar etc. Is.

[0002]

2. Description of the Related Art Various transfer paths such as a moving walkway for transferring people or transferring various articles have been proposed in the past. It supports a pair of rotating pulleys that are driven by a chain, wraps a chain around it, attaches a pedestal to the chain, and circulates the pedestal to carry various articles, so that it bears the maximum load. Since it is necessary to design components with high strength, the equipment becomes large and expensive as the maximum working load increases, and there are many components, which requires a great deal of design work and causes cost increase. It was Moreover, since all the loads are applied to the drive unit, it is necessary to perform regular operation of the maximum horsepower motor according to the maximum working load.
It is difficult to manufacture a transfer device that transfers ultra-heavy objects, because there is a waste of time when there is an empty load, and there is a limit to increasing the horsepower of the motor in terms of cost, and there is also a structural limit to increasing the strength of the structure. There was a problem.

In order to solve such a problem, the applicant of the present invention, as disclosed in Japanese Unexamined Patent Publication No. 1-256490, provides rotary pulleys that rotate about the horizontal axis at the front and rear ends of the water tank. By continuously mounting a large number of floats whose treads are located slightly above the liquid level on the upper surface of the chain belt that is wound around the rotating pulley, it is possible to apply all the load to various components such as the drive part due to buoyancy. Although a floating walkway that does not exist is proposed, this prior invention requires improvement in practical use because it requires a drive source for each round trip path.

[0004]

The problem to be solved by the present invention is to solve the above-mentioned problems and prevent the use of the buoyancy force to apply all loads to various components such as the drive section. In this respect, it is the same as the invention of the prior application, but it is possible to drive the reciprocating path with only one driving source and also to transfer super heavy objects. It is to provide a floating conveyance path.

[0005]

SUMMARY OF THE INVENTION A water surface floating type conveyance path according to the present invention, which has solved the above-mentioned problems, is operated between a first base and a second base connected by a water surface by operating a drive mechanism between the two bases. A transfer means and a circulation guide mechanism for horizontally circulating the
A large number of floats that float on the water surface are continuously connected to the circulation guide mechanism, and forward and backward paths are formed between the two bases, in which the floats continuously move in the opposite direction on the water surface in accordance with the operation of the transfer means. It is characterized by that.

[0006]

In such a water-floating transport path, the drive mechanism is operated to slowly and horizontally rotate the transfer means along the circulation guide mechanism so that the transfer guide is continuously connected to the transfer means while being guided by the circulation guide mechanism. The many floats that are turned rotate while levitating above the water surface, and the forward and return paths formed by the above-mentioned multiple floats on the water surface between the first base and the second base travel in opposite directions. If people or various items are placed on the float at the base, they will be automatically transferred to the other base.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a mobile walkway illustrating the present invention will be described in detail as an embodiment. Reference numeral 1 denotes a loop type water tank laid between the first base A and the second base B. The loop type water tank 1 is provided in a recessed groove dug as a volume capable of obtaining buoyancy corresponding to the maximum working load. is set up. 2 is a loop type water tank 1
Is a drive mechanism provided at the front and rear ends of the vehicle, and at least one of the two drive mechanisms 2 and 2 has a motor 4 with a brake that is attached to the frame 3 of the loop-type water tank 1 as a drive source and is rotatable in the forward and reverse directions. The chain as the transfer means 9 is rotated as described later via the planetary gear speed reducer 4a connected to this and the rotary pulley 5 attached to the output shaft thereof. The motor 4 serving as the drive source of the drive mechanism 2 is usually provided in either one or both of the front and rear, but when the total length is long, an appropriate number may be additionally provided in the middle. Is.

Reference numeral 7 denotes a large number of disk-shaped floats which are continuously floated in the loop type water tank 1.
Is floated above the water surface in the loop type water tank 1 and guided by a circulation guide mechanism 8 provided in the loop type water tank 1. Then, the large number of floats 7 are linked to the chain at the bottom as the transfer means 9 that circulates by the drive mechanism 2 and circulates along the loop type water tank 1, and both linear portions of the circulation guide mechanism 8 between both bases. Along with the operation of the transfer means 9, the float 7 continuously forms a forward path C and a backward path D which travel in the opposite direction on the water surface.

The front and rear end surfaces of each float 7 are formed into a convex arc surface 7a and a concave arc surface 7b which are formed by an arc R with the center of the connecting pin 9a of the chain as the transfer means 9 as the middle point. The floats 7 in contact with the front and rear end faces are continuously arranged so that they can be bent and rotated, and can be circulated and moved along a conveyance path having a curvature of the loop type water tank 1, and the arc R is R = W / 2. It is half the width W of the float 7. In addition, the float 7 is a roller 1 for stopping vertical movement.
0 and the left and right steady rests 11 are fitted in the peripheral frames provided at the front and rear positions of both side surfaces so that they can be slid up and down slightly. In the figure, 7c is a tread plate attached to the upper surface of the float 7.
The c is located above the cover plate, which will be described later, and also has a function of preventing dust and the like from entering the loop type water tank 1.

On the other hand, the circulation guide mechanism 8 includes a pair of guide rails 12 and 13 for rotatably engaging the vertical steadying roller 10 and the horizontal steadying roller 11 of the float 7 with one guide. The rail 12 is provided on the inner surface of the outer wall of the loop type water tank 1, but the other guide rail 13 facing the rail 12 is provided on the inner surface of the outer wall of the straight portion of the loop type water tank 1. The bent portions at both ends are provided on the outer surface of the cylindrical member 5a that drives the rotary pulley 5 of the drive mechanism 2. The amount of liquid in the loop-type water tank 1 is adjusted so that the guide roller 12 and the guide rail 13 do not come into pressure contact with each other due to fluctuations in the load, so that the guide rollers 10 and 11 have the smallest rolling resistance with respect to the guide rail 13. Controlled, 1 in the figure
Reference numeral 4 denotes a cover plate that exposes only the outward path C and the return path D of the loop-type water tank 1 and covers the other portions, so that the portions continuing to both ends of the loop-type water tank 1, that is, the first base A and the second base B
The enlarged and bent portions at both ends of the circulation guide mechanism 8 facing the vehicle are concealed to form a platform for getting on and off. Further, the resistance may be automatically measured according to the load of the motor 4, and the resistance may be automatically controlled so as to keep the minimum resistance.

With the structure as described above, when the motor 4 with a brake is driven, the rotary pulley 5 of the drive mechanism 2 is driven.
Since the chain as the transfer means 9 wound around the loop moves, a large number of floats 7 that are continuously floating in the loop-type water tank 1 circulate and move along the circulation guide mechanism 8 of the loop-type water tank 1. Will be done. And the first
Outgoing route C consisting of a float 7 that circulates from a platform formed by a cover plate 14 at the base A or the second base B.
Alternatively, if a person or various articles are placed on the return path D, the person or various articles can be smoothly moved by the float 7 that circulates in the loop type water tank 1 in a floating state.
It will be transferred to base A.

Since each float 7 forming the outward path A and the return path B during the transportation of the person or article in this manner is floated by the liquid in the loop type water tank 1, the rolling resistance of the float 7 is extremely small, The drive mechanism 2 can be downsized to reduce power consumption, and since the strength of the structure can be small, the cost of parts can be kept low, and the number of constituent parts is small and the design is easy. Moreover, since the strength of the loop-type water tank 1 can be reduced by burying the loop-type water tank 1 in the ground, it is not necessary to construct a structure having high strength even when transporting an ultra-heavy object, and the cost is low. Can be provided. Further, since the transfer route of the loop type water tank 1 includes straight lines and curved lines, it is possible to easily set the optimum route even if there is an obstacle.

As in the embodiment, the first base A and the second base A
A loop type water tank 1 is installed between the base B and the base filled with water to connect both bases on the water surface.
It is particularly preferable because it can be fixed not on the surface of the sea or the surface of the lake but on the ground, and it can be controlled by adjusting the liquid volume by changing the load so that the rolling resistance can be minimized. A pair of guide rails 1 in which a mechanism 8 is below the water surface and rotatably engages guide rollers provided on the outer wall of each float 7 which also functions as a steady rest.
2 and 13, and the transfer means 9 is provided for each float 7.
The horizontally rotatable chain, which is connected to the bottom of the chain and circulates under the water surface by the drive mechanism 2, has the advantages of good stability, simple structure, and low cost. Further, the circulation guide mechanism 8 is composed of two parallel straight portions and an arc-shaped enlarged bent portion connecting both ends thereof,
The drive mechanism 2 is provided in at least one of the enlarged bending portions, and the forward path C and the return path D are formed in two parallel straight portions, which requires a minimum installation area. If the disk-shaped body is formed on the arc surface 7a and the other end is formed on the concave arc surface 7b corresponding to the convex arc surface 7a, the continuity in the outward path C and the return path D is good, and at the bent portions at both ends. The stability is particularly good, and the part where both ends of the outward path C and the inward path D are covered with the cover plate 14 to form the platform is not only good in appearance but also convenient for getting on and off people and transported articles. Is.

In the embodiment, a moving walkway for transporting people and various articles is used. However, for example, it is used when an airplane is parked at an airfield to save airplane fuel, reduce exhaust gas, or park a car. It can be used at the time of shipping or shipping, or can be applied to the transportation of various products in a manufacturing plant, etc., and its installation can be done by excavating the ground as in the example, or below the water surface between land and island. Further, in the embodiment, the loop type water tank 1 has an elongated loop shape in which the outward path C and the return path D are simply arranged in parallel, but it is needless to say that the path can be freely set such as a circular shape or a deformed loop shape. .

[0015]

As is apparent from the above description, the present invention is designed so that a person floated by the liquid in the loop type water tank and various articles are circulated and moved, so that all the loads are applied to the drive section. Therefore, the motor can be downsized and power consumption can be reduced, and the strength of the structure can be reduced to keep the cost of parts low. It will be easy. In addition, the reciprocating path can be driven by a single drive source, super heavy objects can be transferred, and a large number of floats are continuously arranged horizontally in an annular shape, so that the transfer path of the loop-type water tank is straight or straight. It is possible to include a curve, and there is also an advantage that the optimum route can be easily set even if there is an obstacle. Therefore, the present invention is extremely useful as a water surface floating type conveyance path which solves the conventional problems.
