[0002] When installing the partition plates in shield tunnels, the original segment transport tracks need to be removed.

The usual practice is to use small flatbed trucks to transport materials. However, due to the large horizontal and vertical curvature of the shield line, and the unfilled hand holes and grouting holes on the segments, small flatbed trucks often run off the track, overturn, get stuck, and other faults in the circular shield, requiring frequent manual adjustments, which greatly reduces the efficiency of material transportation.

[0047] Reference Figures 1 to 3 The self-balancing transport vehicle of the first embodiment of the present application is used for construction in shield tunnels and circular pipes. The self-balancing transport vehicle includes a chassis 100, a driving wheel group, a left driving component 300, a right driving component 400, a gyroscope sensor component 500 and a control device.

[0048] The driving wheel group includes a left driving wheel 210 and a right driving wheel 220 respectively arranged on the left and right sides of the chassis 100; the left driving component 300 is arranged on the chassis 100 and is used to drive the left driving wheel 210; the right driving component 400 is arranged on the chassis 100 and is used to drive the right driving wheel 220; the gyroscope sensor component 500 is arranged on the chassis 100 and is used to detect the lateral inclination ratio of the chassis 100; the control device is configured to be able to calculate the adjustment parameter according to the information of the gyroscope sensor component 500, and adjust the output power of at least one of the left driving component 300 or the right driving component 400 according to the adjustment parameter.

[0049] It can be understood that the two driving wheel groups are respectively located on both sides of the front of the chassis 100, and the transport vehicle moves through the two driving wheel groups. The two driving components are located on the chassis 100 and provide power for the two driving wheel groups. The two driving components can independently adjust the output power; the gyroscope sensor component 500 is used to convert the lateral inclination angle ratio of the chassis 100 into an electrical signal reading, and then automatically adjust the output power of the right or left driving component.

[0050] In some embodiments, the control device is used to receive information from the gyro sensor component 500 and is capable of adjusting the output power of at least one of the left driving component 300 or the right driving component 400.

[0051] It should be noted that the self-balancing transport vehicle of the present application uses a gyroscope sensor component 500 to detect the inclination information of the transport vehicle, and controls the output power of at least one of the left drive component 300 or the right drive component 400 when turning or transporting on a curved line, thereby ensuring that the transport vehicle can automatically correct its deviation and prevent rollover, thereby greatly improving the material transportation efficiency.

[0052] In some embodiments of the present application, the control device calculates the electrical signal proportionally to increase or decrease the output power of the right driving component 400 through a function, and the function is: Qright=K×G+Qleft;

[0053] Among them, K is the electrical signal amplification factor, G is the reading of the gyroscope sensor component 500, Qright is the output power of the right driving component 400, and Qleft is the output power of the left driving component 300.

[0054] In some embodiments, the gyro sensor component 500 is disposed behind the right driving component 400 to convert the lateral tilt angle ratio of the chassis 100 into an electrical signal reading, thereby automatically adjusting the output power of the right motor.

[0056] It is understandable that the gyro sensor can convert the horizontal tilt reading of the chassis 100 into an electrical signal proportionally increasing or decreasing the right motor output power through the function "right motor power = K × reading + left motor power", where K is the electrical signal amplification factor (generally set to -1), and the left motor power is the initial power (generally set to 50). When the left side of the transport vehicle is raised, the gyro sensor outputs a positive tilt angle, the right motor power decreases, and the transport vehicle turns right back to the positive position; when the right side of the transport vehicle is raised, the gyro sensor outputs a negative tilt angle, the right motor power increases, and the transport vehicle turns left back to the positive position.

[0057] In some embodiments, the power of the left driving component 300 is set as the initial power, and the control device can be used to adjust the K value and the parameters of the initial power. In addition, the parameter K value and the parameter initial power of the gyro sensor can be adjusted. It should be noted that by using the power of the left driving component 300 as the initial power and only controlling the output power of the right driving component 400 to achieve automatic deviation correction, the control method can be simplified and the control accuracy can be improved.

[0058] In some embodiments of the present application, the self-balancing transport vehicle further includes a driven wheel set 600, which is respectively arranged on the left and right sides of the chassis 100 opposite to the other end of the driving wheel set.

It is understandable that the driven wheel assembly 600 includes a wheel seat 430 and a driven wheel, the wheel seat 430 is welded to the chassis 100, and the driven wheel is connected to the wheel seat 430 via a bearing. The row of wheels used can also effectively avoid wheel jamming, thereby greatly improving material transportation efficiency.

[0060] In some embodiments of the present application, at least one of the left driving component 300 or the right driving component includes a motor 410, a gear box 420, a wheel seat 430 and a driving wheel, the gear box 420 is disposed on the chassis 100 and is used to connect the motor 410 and the driving wheel respectively, the wheel seat 430 is disposed on the chassis 100, and the driving wheel is rotatably disposed on the wheel seat 430 and is used to output power. It can be understood that the gear box 420 is fixedly disposed on the chassis 100 and is located in front of the motor, the gear box 420 transmits the motor power to the driving wheel, the wheel seat 430 is welded to the bottom of the chassis 100, and the wheel seat 430 is connected to the driving wheel through a bearing.

[0061] In some embodiments, the left driving component 300 and the right driving component have the same structure, both including a motor 410, a gear box 420, a wheel seat 430 and a driving wheel. The motor 410 of the left driving component 300 drives the left driving wheel 210 through the gear box 420, and the wheel seat 430 of the left driving component 300 is used to set the left driving wheel 210. The motor 410 of the right driving component 400 drives the right driving wheel 220 through the gear box 420, and the wheel seat 430 of the right driving component 400 is used to set the right driving wheel 220.

[0062] In some embodiments of the present application, the chassis 100 is further provided with guardrails 110, which are respectively arranged at the peripheries of the left driving component 300 and the right driving component 400, and the gyroscope sensor component 500 is arranged in one of the guardrails 110.

[0064] In some embodiments of the present application, the chassis 100 is further provided with an armrest 120 and a battery component 130. The armrest 120 is provided on both sides of the chassis 100. The battery component 130 is used to supply power to the left driving component 300 and the right driving component 400. It can be understood that the armrest 120 is used to prevent the transported items from rolling down. The battery is provided behind the right motor to supply power to the two motors.

[0065] In some embodiments, the chassis 100 includes a frame 101 and a panel 102 disposed on the frame 101. The frame 101 is welded from square steel and is a "mouth"-shaped frame with internal scissor braces for reinforcement. The panel 102 is a rectangular thin iron sheet with the same projection area as the frame 101, and the panel 102 is welded to the frame 101.

[0066] Reference Figures 1 to 3 The control method of the self-balancing transport vehicle of the second embodiment of the present application may be the control method of the self-balancing transport vehicle of the first embodiment of the present application, and the control method of the self-balancing transport vehicle comprises the following steps:

[0067] The initial parameter state of the chassis 100 is set, the left driving component 300 drives the left driving wheel 210 according to the first preset power, and the right driving component 400 drives the right driving wheel 220 according to the second preset power;

[0068] The gyro sensor component 500 obtains the lateral tilt angle ratio of the chassis 100 and compares it with the initial parameter state of the chassis 100;

[0069] The adjustment parameter is calculated based on the information obtained by the gyro sensor component 500, and at least one of the left driving component 300 or the right driving component 400 responds to the adjustment parameter and controls the output power to restore the chassis 100 to the initial parameter state.

[0070] In some embodiments of the present application, when the left side of the chassis 100 is raised, the gyroscope sensor component 500 outputs a positive tilt angle, and the power of the right drive component 400 is reduced to make the chassis 100 turn right and return to the center; when the right side of the chassis 100 is raised, the gyroscope sensor component 500 outputs a negative tilt angle, and the power of the right drive component 400 is increased to make the chassis 100 turn left and return to the center. It can be understood that by only controlling the output power of the right drive component 400 to achieve automatic deviation correction, the control method can be simplified and the control accuracy can be improved.

[0071] In some embodiments of the present application, there are two driving wheel groups, which are arranged in front of both sides of the chassis 100, and the driving wheel groups are used to drive the materials on the transport vehicle to move. There are two motors, and the two motors provide power for the two driving wheel groups respectively. The battery is located behind the right motor, and the two motors are powered by cables. The gyroscope sensor is located on the chassis 100, and the gyroscope sensor is used to convert the lateral inclination reading of the chassis 100 into an electrical signal and then change the power of the right motor. There are two guard plates, and the two guard plates respectively protect the motors, batteries and gyroscope sensors on both sides. There are two driven wheel groups 600, and the two driven wheel groups 600 are respectively located behind both sides of the chassis 100, and the driven wheel groups 600 are used to support the transport vehicle. There are two handrails 120, and the two handrails 1200 are respectively located on both sides of the chassis 100 to prevent the transported materials from rolling off.

[0072] When in use, the chassis 100 carries the material, the transport vehicle is placed horizontally on the shield tunnel segment, the driving wheel group faces the forward direction, the chassis 100 carries the material, and the motor is started to move. When the tunnel line turns right, because the tunnel is a circular cross-section, the left side of the chassis 100 rises, and the gyroscope sensor outputs a positive inclination angle, which is converted into an electrical signal ratio through the function "right motor power = K (generally -1) × reading + left motor power (generally 50)" to reduce the right motor power, the left motor power remains unchanged, and the transport vehicle turns right to return the chassis 100 to zero; when the tunnel line turns left, the right side of the chassis 100 rises, the gyroscope sensor outputs a negative inclination angle, and then increases the right motor power, the left motor power remains unchanged, and the transport vehicle turns left to return the chassis 100 to zero.
