Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for towing an automobile in a specific location, such as in a long tunnel, by an electric drive, particularly by a linear motor drive, with the internal combustion engine of the automobile stopped. It is.

Generally, when a car or the like is driven under its own power in a tunnel, exhaust gas emitted by the internal combustion engine remains in the tunnel, and unless strong ventilation is performed, the air inside the tunnel becomes increasingly polluted, creating an extremely dangerous situation. For this reason, tunnels are equipped with powerful ventilation systems, but in the case of long tunnels, the tunnel used for this ventilation air passage may be much larger.
The amount of tunnel excavation is increasing, which is directly linked to tunnel construction costs, and has become a very big problem. As a means of solving this problem, a mechanism for transporting automobiles that supports parts of the vehicle such as the front wheels and is towed by electric drive has already been proposed in Japanese Patent Application Nos. 50-151371 and 1987-148772. .

Therefore, the purpose of the present invention is to provide an optimal overall structure when a linear motor is incorporated in order to solve the problems in the previously proposed electrically driven vehicle transportation mechanism, in order to reduce the number of moving parts and facilitate maintenance. I'll decide.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Further, a hanging beam 15 is provided near the center of the lower surface of the support beam 2 so as to protrude inward from the groove 8a on the lower side of the vehicle running road surface 8, and a control box 16 such as a linear motor is installed at the bottom of the hanging beam 15. installed. The control box 16 has a rectangular shape that is long in the front and back, and a linear motor primary 17 is attached to the upper part of the control box so as to protrude forward in the direction of travel and face a vertical surface 18a of a linear motor secondary plate 18, which will be described later. There is.
The linear motor secondary plate 18 is connected to the automobile traveling road surface 8.
A groove 8 provided along the center of the running road surface 8 on the lower side.
It is vertically attached to one side of the groove 8a which also serves as one side of the left and right guide walls 19, 20 in the groove 8a. The control box 16 has a linear motor secondary plate 18 which also serves as a guide wall 19 on one side of the groove 8a.
A guide mechanism 21 is provided which maintains an appropriate gap between the vertical plane of the tow vehicle 1 and the linear motor primary 17 and guides the tow vehicle 1 so that it can travel. This mechanism 21 consists of L-shaped support arms 22 and 23 which have high rigidity and are fixed to the front end and approximately the center of the upper surface of the control box 16.
The front and rear guide wheels 24 and 25 attached to be in rolling contact with the guide wall 19 on one side, which is the linear motor secondary plate 18, and the hinges 26 and 27 at the proximal ends of the support arms 22 and 23 are Rotating arm 3 that can rotate around the center and is pressed by spring mechanisms 28 and 29

The left and right guide walls 19 and 20 are integrally formed with a lip groove shape in cross section extending over both sides and the bottom of the groove 8a, and the upper surfaces of the projecting portions 34 and 35 on both sides are flush with the road surface 8 on which the vehicle is running. , and the hanging beam 15 and the front and rear piston cylinders 13, 1
There are slits at small intervals that allow the vehicle A to pass through, and even if the vehicle A passes over the slits, the tire a of the vehicle A is configured so as not to cause any inconvenience such as getting stuck in the tire a. Consideration has been made so that no problem will occur even if the automobile A passes not only in the longitudinal direction of the automobile traveling road surface 8 but also in the right angle direction.

Next, the functions of the linear motor-driven automobile traction device of the present invention will be explained.

First, the support beam 2 of the towing vehicle 1 and the front and rear wheel press plates 1
The functions of 1 and 12 are that when loading the front wheels a and a of the automobile A, the piston cylinder 13 is extended and the front wheel press plate 11 is raised to stand up, and the piston cylinder 14 is retracted to raise the rear wheel press plate 12. falls to a position where its tip almost touches the running road surface 8. In this state, the car A runs under its own power and the front wheels a and
Put a on it. In this case, the car A is moved until the front wheels a and a touch the front wheel press plate 12 and then stopped, so there is no need for the driver of the car A to have advanced skills, and even beginners can easily follow the instructions. It can be stopped at a certain position. When it is detected by an appropriate means that the front wheels a, a are placed on the support beam 2, the piston cylinder 14 is actuated and the rear wheel press plate 1 is activated.
2 rises, and the front wheels a, a of the automobile A are supported by the front and rear wheel press plates 11, 12 and the support beam 2 so as not to come off, and all the load is transferred to the running wheels 4, 5, 6,
7, the support beam 2 is movable while maintaining a necessary minimum gap with the running road surface 8 or the upper surfaces of the overhanging portions 34, 35. Furthermore, when the tow vehicle 1 reaches its destination and unloads the vehicle, the linear motor drive is stopped, the piston cylinders 13 and 14 are retracted, and the front and rear wheel press plates 11 and 12 are overturned so that their tips end on the road surface. Make it so that it comes in contact with In this state, car A starts the engine and moves the wheel press plate 1 under its own power.
1, and the rear wheels also move forward with this wheel holding plate 11,
12, the vehicle A can be separated from the tow vehicle 1 very easily by climbing over the support beam 2.

Next, describing the running of the towing vehicle 1, the distance between the linear motor primary 17 and the guide wall 19 which also serves as the vertical surface 18a of the linear motor secondary plate 18 is provided by the front and rear guide wheels 24, 25 on one side of the guide mechanism 21. Since a constant gap is always maintained, the thrust necessary for running and decelerating can be easily secured, and the guiding wall 20 on the opposite side
Since the front and rear guide wheels 32 and 33 on the other side, which have a spring action, are always pressed against the guide wheels 32 and 33, the linear motor primary 17 is aligned with the vertical surface 18a of the linear motor secondary plate 18. It is also prevented from leaving the guide wall 19. Also, due to this spring action, the left and right guide walls 19 and 20
Even if there is an irregularity in the interval between the two, no problem will occur in guided running.

Here, the front guide wheels 24, 32 are located far forward in the traveling direction with respect to the running wheels 4, 5, 6, 7, and the rear guide wheels 25, 33 are located far ahead of the running wheels 4, 5, 6, 7. The front and rear guide wheels 24 and 25 on one side are quite rigidly connected to the hanging beam 15 and the support beam 2 via the support arms 22 and 23 and the control box 16, so the following It has inductive properties. In other words, the rear guide wheels 25, 33, combined with the cornering force of the running wheels 4, 5, 6, 7, make it very difficult to move this device from side to side. However, running wheels 4, 5, 6,
When the guide wheels 24, 32 located far ahead of the guide wheels 7 detect the displacement along the left and right guide walls 19, 20 and attempt to steer the entire towing vehicle 1 to the right or left, the traveling wheels 4, 5, 6, There is no need for sideslip 7 at all, and the difference in rotational speed between the left and right running wheels 4, 5 and 6, 7 makes it possible to easily change direction, making it possible to guide the entire towing vehicle 1 smoothly. This mechanism has characteristics that are significantly different from conventional devices in that the linear motor primary 17 maintains an appropriate gap with the guide wall 19, which is the vertical surface 18a of the linear motor secondary plate 18, and the towing vehicle 1 Running wheels 4,
5, 6, and 7 through the hanging beams 15, the linear motor primary 17 can maintain an appropriate position in the rolling direction without providing guidance in the rolling direction, and the rear guide wheels 25, 33 is near the running wheels 4, 5, 6, 7, and the front guide wheels 24, 32 are far ahead,
When guided traveling along the guiding walls 19, 20, the traveling wheels 4, 5, 6, 7 are not caused to skid at all and the guided traveling can be carried out easily. Furthermore, the linear motor primary 17 is connected to the vertical surface 18 of the linear motor secondary plate 18.
Since it is facing A, the car A is placed on top of the support beam 2.
Even if the front wheels a and a of the towing vehicle 1 ride on it, causing the traveling wheels 4, 5, 6, and 7 to bend, or even if the overall height of the towing vehicle 1 changes due to wear, etc., it will not be affected at all, which is unthinkable with conventional devices. It is possible to obtain advantages that are not available.

Although the above explanation did not mention the power supply system for this device, it is necessary to explain it in particular because it is possible to easily arrange rigid overhead wires, etc. by using the space in the groove 8a below the control box 16 for linear motors, etc. It is thought that there is no such thing.

In addition, the branching mechanism where the running path 8 is divided into two parts is as shown in FIG. If it can be rotated, it can be easily configured.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 to 7. In this case, the left and right guide walls 19, 20 in the groove 8a on the lower side of the running road surface 8 also serve as linear motor secondary plates 18, 18', respectively, and the guide walls 19, 20 are placed on both sides of the upper surface of the control box 16.
The primary linear motors 17 and 17' are installed to face the linear motors 17 and 17' on the other side.
Reference numeral 7 indicates an anchor 42 that transmits thrust to support the guide wheels 32 and 33, and a spring mechanism 28 that obtains a pressing force.
It is attached to an arm frame 30a which is displaceably provided via 29. In this way, the car A to be towed
Even if the weight of the linear motor is excessive and the linear motor primary 17 must be made extremely large, it is easy to
Thrust can be obtained by the primary linear motors 17 and 17'. In addition, as shown in FIG.
A movable guide rail 4 is provided as shown in Figures 6 and 7.
7, 48 on the inner bottom surface of the groove 8a with hinges 49, 50.
If the movable guide rails 47, 48 are rotatable by piston cylinders 51, 52, and the fixed guide rails 53, 54 are installed only in the branch section so as to be continuous behind them, the movable guide rails 47, 48 fixed guide One of the rails 52, 53 can be combined with one of the branch wheels 43, 44 or 45, 46 to allow branching, and the movable part of the branch can be made extremely small.

In addition, with the device of the present invention, when the towing vehicle 1 is used at very low speeds, or when there is no need to consider reversing at all, the cornering force of the supporting wheels 4, 5, 6, and 7 can be expected to be sufficient. In some cases, even if the guide wheels 25, 33 are omitted, it can be expected that the running characteristics will not change substantially. For this reason, it is possible to consider a system in which the guide wheels 25 and 33 are completely omitted, or the guide wheels 25 and 33 are not in contact with each other at all times, but are brought into contact with the sliding shoe only when an abnormal displacement occurs to guide the guide wheels.
