Detailed ways

The concrete structure of the present invention is further described below:

The structure of the two-way rail car is shown in Figure 1. It includes a carriage 1. The bottom of the carriage 1 is provided with a front moving wheel pair 2 and a rear moving wheel pair 3. Each pair of moving wheels includes two wheels, and the two wheels are respectively arranged in the carriage 1. The lower sides form the wheelset. The axles of the front moving wheel pair 2 and the rear moving wheel pair 3 are respectively connected with one end of the steering connecting shaft 4, and the other ends of the two steering connecting shafts 4 are hinged with the two ends of the steering connecting rod 5. The middle position is hinged to one end of the swing steering rod. The middle part of the swing steering rod is provided with a fixed shaft 7. The fixed shaft 7 is fixed at the bottom of the carriage 1. The other end of the swing rotation rod is provided with a vertically arranged guide rod 8. The guide rod 8 The lower end of the guide wheel 9 is provided with a guide wheel 9, the guide wheel 9 is arranged in the track, and the track restricts the guide wheel 9 to move along the track direction. The axle of the guide wheel 9 is arranged vertically, and the track is a track groove under the ground or a guide rail with grooves on the ground.

The swing steering rod connected to the front moving wheel pair 2 faces the front of the vehicle compartment, and the guide rod 8 on the front side of the front moving wheel pair 2 is located in front of the vehicle compartment 1 . The swing steering rod to which the rear moving wheel pair 3 is attached faces the rear of the cabin. The guide rod 8 behind the rear moving wheel pair 3 is located behind the carriage 1 . The front and rear guide wheel pairs ensure that the moving wheels and the carriage are always moving along the track.

The bottom of the carriage 1 is provided with a battery 10, and the wheels of the front moving wheel set and the rear moving wheel set are electric wheels with built-in motors. The rear of the carriage 1 is provided with a steering handle 11, the middle of the steering handle 11 is a steering shaft 12, the steering shaft 12 is hinged on the rear side of the carriage 1, the lower end of the steering shaft 12 is provided with a swing rod 13, and the front end of the swing rod 13 is hinged to the into the steering slot on the swing steering lever.

A folding seat 14 is provided on the rear side of the carriage 1, and the folding seat 14 can be laid flat or folded upward. Footrests 15 protruding from the rear side of the carriage 1 are provided on both sides of the foldable seat 14 and near the bottom of the carriage 1 , and a brake 16 is provided at one footrest, and the brake 16 controls the braking of the moving wheelset.

The front and rear sides of the carriage 1 are respectively provided with anti-collision rods 17, and a buffer spring 18 is arranged between the inner side of the square hit rod and the outer wall of the carriage 1. The buffer spring 18 is sleeved on the buffer rod 19, and the length of the buffer rod 19 is shorter than that of the buffer spring. 18 length, the buffer rod 19 is fixed on the carriage 1.

Cameras are provided on the front and rear sides of the carriage 1 , and the cameras are used to monitor and scan the front and rear of the carriage 1 . An anti-collision travel switch is arranged between the anti-collision bar and the compartment wall at the front and rear of the carriage. When the buffer spring is compressed to a certain extent, the anti-collision bar touches the travel switch, and the internal motor of the wheel, which forms a circuit interconnection with the travel switch, stops rotating to realize Anti-collision function.

The guide rod 8 is hinged to the swing steering rod 6, and the direction of the hinge shaft is horizontal. A fixed latch 20 with an inner groove is provided in the middle of the front or rear edge of the lower side of the carriage 1, and the guide rod 8 surrounds the end of the swing steering rod. When it is rotated to the bottom of the carriage 1 to the position of the fixed latch 20, it can be embedded in the inner groove and fixed, the guide rod 8 and the guide wheel 9 are retracted from the track, and the carriage 1 can be moved on the ordinary ground.

The lower side of the swing steering rod at the rear of the carriage 1 is also provided with a mobile lock 21, and the mobile lock 21 is also provided with an inner groove. The lowest position of the groove is lower than the fixed lock 20, and when the guide rod 8 at the rear of the carriage 1 is rotated to be embedded in the inner groove of the mobile lock 21 and the fixed lock 20 at the same time, the steering of the rear moving wheel pair 3 will be locked and prevented. Cannot turn again.

How this device works:

Take the carriage of the device as the forward direction without the handle, the front guide wheel is placed in the track with the guide groove at the same time, the rear guide rod is folded and embedded in the moving lock and the fixed lock, and the rear moving wheel is connected to the carriage. The length direction is the same. The motor in the wheel starts to drive the carriage to move. When the track is in the bending position, the front guide wheel deflects in the track along the track bending direction, the guide rod drives the swing steering rod to swing around the fixed axis, the swing steering rod drives the steering connecting rod and the steering connecting shaft to swing, and the steering connecting shaft drives the wheel. The wheel frame rotates, and the rotation direction is consistent with the bending direction of the track. When the carriage travels in the opposite direction, the guide rods at the front and rear of the carriage are arranged in the opposite direction to the above, and the handlebar will rotate correspondingly with the direction of the track. In addition, at this time, the connection position between the steering shaft and the swing rod can also be separated, and the handlebar function is invalid.

When the rail car arrives at the warehouse or other destination, the anti-collision bar collides with the limit device at the destination position, triggering the emergency stop travel switch to realize the driving stop.

After unloading, it runs in reverse direction. At this time, the guide wheel in the front guide rail is lifted and stuck in the parallel fixed lock, and the front moving wheel pair will no longer rotate relative to the carriage. The guide wheels connected to the rear moving wheel pair are put into the guide rails, and in this case, the guide rods are rotatably interconnected with the corresponding swing steering rods, steering connecting rods and steering connecting shafts.

The carriage moves under the drive of the moving wheel pair, the guide wheels in the rear direction travel along the track track, and the track travel mode along the curved position is the same as the above, until the stop position is reached, and the switch is touched to stop the operation.

Manned operation, and the functions on ordinary ground are realized:

First, turn the guide rod in the direction of the front moving wheel set to be embedded in the fixed lock, and the guide rod in the direction of the rear moving wheel set is embedded in the mobile lock. It is linked with the swing steering rod, steering connecting rod and steering connecting shaft. Turning the handlebar can drive the rotation of the rear moving wheelset.

Open the seat 14 and turn the handlebar to control the walking direction, so as to realize the use of the driver on ordinary ground.
