Detailed implementation manners

[0038] To make the purpose, principle and structure of the present invention clearer, the following further elaborates with reference to the attached drawings and specific embodiments.

[0039] Embodiment 1: A structure of a road-rail dual-purpose power flatbed truck.

[0040] In order to achieve the purpose of greatly improving the transportation efficiency of the rail flatbed truck, the following introduces the composition of the right-side framework of the flatbed truck. The left and right sides of this device are symmetrical, and the left-side structure is the same as the right side.

[0041] See Figures 1 to 15, the rail-road dual-purpose power flatbed mainly consists of six main components: the flatbed surface 1, the power device, the power switching device, the speed measuring device 9, the braking device 10, and the control device. The power device is composed of multiple parts such as the rotating device support frame 12, the motor 13, the rotating connecting rod 14, the transmission belt 15, the steel wheel driven wheel 16, the steel wheel bearing 17, the motor fixing bracket 18, the motor driving wheel 19, and the motor output shaft 20. The power switching device is composed of multiple parts such as the deformation rod gear 2, the deformation rod 3, the upper power push rod rack 4, the lower power push rod rack 5, the upper power push rod 6, the lower power push rod 11, the front wheel 31, the front wheel support rod 32, the front wheel support rod fixing shaft 33, the front wheel fixing screw 34, the front wheel support frame 35, the deformation rod gear fixing bracket 36, and the upper and lower power push rod rack fixing bracket 39. The speed measuring device 9 is composed of multiple parts such as the spring core shaft 9-1, the spring housing 9-2, the spring 9-3, the speed measuring wheel 9-4, the punched ear plate 9-5, and the encoder 9-6. The control device is composed of two parts: the remote control 29 and the main control device 38.

[0042] The key parts of the whole device are the power device, the power switching device, and the speed measuring device. The composition structures of the three devices are described in detail below.

[0043] The composition structure of the power device is as follows: The rotating device support frame 12 is fixed on the flatbed surface 1. The rotating connecting rod 14 is fixed to the rotating device support frame 12 through the deformation rod 3. The two ends of the rotating connecting rod 14 are respectively connected to the motor fixing bracket 18 and the power steel wheel 7. The motor 13 is fixed on the motor fixing bracket 18 to provide power for the flatbed. The motor 13 outputs power through the motor output shaft 20 to the motor driving wheel 19 fixed on the motor output shaft 20 and the power wheel 8. The motor driving wheel 19 is connected to the steel wheel driven wheel 16 through the transmission belt 15 and transmits the power output by the motor 13 to the steel wheel driven wheel 16. The steel wheel driven wheel 16 is connected to the power steel wheel 7 through the steel wheel bearing 17, thereby driving the power steel wheel 7 to rotate. Through the transmission of the above master and slave driving wheels, the motor can drive the power steel wheel 7 and the power wheel 8 to rotate, thereby pushing the flatbed forward.

[0044] The composition structure of the power switching device is as follows: The upper power push rod 6 and the lower power push rod 11 are respectively fixed above and below the flatbed surface 1. The upper and lower power push rod rack fixing brackets 39 and the deformation rod gear fixing bracket 36 respectively fix the positions of the upper power push rod rack 4, the lower power push rod rack 5, and the deformation rod gear 2. The upper power push rod rack 4 and the lower power push rod rack 5 are respectively fixed at the tops of the upper power push rod 6 and the lower power push rod 11. The deformation rod gear 2 is fixed in the middle of the deformation rod 3. The deformation rod 3 is fixed to the rotating connecting rod 14 through the connecting hole in the rotating device support frame 12, and according to Figure 8As shown in the schematic diagram of the rotating rod structure, since the rotating connecting rod 14 is an L-shaped structure, its rotation angle is 0-180 degrees. The deformed rod gear 2 meshes with the upper electric push rod rack 4 and the lower electric push rod rack 5. The upper and lower electric push rod racks can drive the deformed rod gear 2, the deformed rod 3 and the rotating connecting rod 14 to rotate through pushing and pulling, so as to realize switching between the two ways of the power steel wheel 7 and the power wheel 8 to provide power for the flatbed truck.

[0045] The composition structure of the speed measuring device is as follows: The encoder 9-6 is fixed to the perforated ear plate 9-5. The speed measuring wheel 9-4 is connected to the encoder 9-6 inside the perforated ear plate 9-5, so that the encoder 9-6 can record the number of turns of the speed measuring wheel 9-4 rotating, thereby measuring the speed. The spring core shaft 9-1 is in the spring 9-3. The spring core shaft 9-1 is fixed to the perforated ear plate 9-5. The spring housing 9-2 is connected to the perforated ear plate 9-5 through the holes on the perforated ear plate 9-5. The spring housing 9-2 is connected to the speed measuring device connecting rod 28. The perforated ear plate 9-5 will move up and down following the deformation of the spring 9-3, and the speed measuring wheel 9-4 can firmly fit the rail 37, thus ensuring that the speed measuring wheel 9-4 reduces the occurrence of slipping and strengthening the accuracy of the encoder 9-6 for speed measurement.

[0046] Embodiment 2: A usage method of a rail-road dual-purpose power flatbed truck.

[0047] A rail-road dual-purpose power flatbed truck has three driving modes, namely driving on the rail using steel wheels, driving on the rail using power wheels, and driving on land. The usage methods for these three modes are as follows.

[0048] Usage method for driving on the rail using steel wheels: First, the operator uses the remote control to control the flatbed truck to enter the steel wheel drive mode. The main control device 38 will read the positions of the upper electric push rod 6 and the lower electric push rod 11, and judge whether the flatbed truck is in the steel wheel drive mode at this time. If it is, the deformation device will not be changed. If not, the self-locking states of the upper and lower electric push rods will be cancelled. The main control device 38 will control the upper electric push rod 6 to drive the upper electric push rod rack 4 to pull back, and the lower electric push rod 11 to drive the lower electric push rod rack 5 to push out. Due to the meshing relationship between the upper electric push rod rack 4, the lower electric push rod rack 5 and the deformed rod gear 2, the above operations will drive the deformed rod gear 2, the deformed rod 3 and the rotating connecting rod 14 to rotate clockwise by 180 degrees, and then the upper electric push rod 6 and the lower electric push rod 11 will enter the self-locking state to fix the position of the deformed rod gear 2 and prevent it from rotating during the driving of the flatbed truck. At this time, the power wheel 8 is on the top and the power steel wheel 7 is on the bottom in contact with the rail 37 to drive the flatbed truck to move. This mode enables the flatbed truck to operate on the standard gauge rail, and can help the flatbed truck pass through railway sections that cannot be passed by using power wheels, such as turnouts, etc., greatly improving the applicability of the flatbed truck.

[0049] Usage method of driving on railway tracks using powered wheels: First, the operator uses the remote control to control the flatbed truck to enter the powered wheel drive mode. The main control device 38 will read the positions of the power-on push rod 6 and the power-off push rod 11, and determine whether the flatbed truck is in the powered wheel drive mode at this time. If it is, the deformation device will not be changed. If not, the self-locking states of the power-on and power-off push rods will be cancelled. The main control device 38 will control the power-on push rod 6 to drive the power-on push rod rack 4 to push out, and the power-off push rod 11 to drive the power-off push rod rack 5 to pull back. Due to the meshing relationship between the power-on push rod rack 4, the power-off push rod rack 5 and the deformation rod gear 2, the above operations will drive the deformation rod gear 2, the deformation rod 3 and the rotating connecting rod 14 to rotate counterclockwise by 180 degrees. Then the power-on push rod 6 and the power-off push rod 11 will enter the self-locking state to fix the position of the deformation rod gear 2 and prevent it from rotating during the driving of the flatbed truck. At this time, the power steel wheel 7 is on top and the powered wheel 8 is in contact with the ground or the roadbed slab to drive the flatbed truck to move. And different lengths of the motor output shaft 20 and different sizes of the powered wheels 8 can be replaced to adapt to different heights and different types of railway tracks. This mode can increase the driving speed of the flatbed truck on the railway tracks and improve the transportation efficiency.

[0050] Usage method for driving on the ground: When driving on land, first use the remote control to control the flatbed truck to enter the powered wheel drive mode. Then manually rotate the front wheel support rod 32 clockwise by 90 degrees around the front wheel support rod fixed shaft 33 so that the front wheel support rod 32 is in a vertical state and the front wheel 31 touches the ground. Then screw the front wheel fixing screw 34 into the front wheel support frame 35 to fix the front wheel support rod 32 to ensure the stability of the flatbed truck when driving on land. If switching to the rail driving state, unscrew the front wheel fixing screw 34 from the front wheel support frame 35 and manually rotate the front wheel support rod 32 counterclockwise by 90 degrees around the front wheel support rod fixed shaft 33 to retract and place it on the front wheel support frame 35.

[0051] Usage method of the speed measurement device: The speed measurement device 9 is connected to the rotating device support frame 12 through the speed measurement device connecting rod 28. When the flatbed truck can measure the speed and acceleration of the flatbed truck through the nine-axis gyroscope in the main control device 38 and when the speed measurement wheel 9-4 contacts the rail 37 when driving on the railway tracks through the encoder 9-6. When it is measured that the speed of the flatbed truck is too fast or the acceleration suddenly increases, the main control device 38 will control the braking device 10 to brake the flatbed truck to prevent safety accidents.

[0052] The above is only the specific implementation manner of this invention, but the protection scope of this invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by this invention, according to the technical solution and the new concept of this invention, makes equivalent substitutions or changes, and should be covered within the protection scope of this invention.
