[0030] The second driving device is connected to at least one of the carriage mechanisms, and is used to drive the two carriage mechanisms to move away from or closer to each other, so that the track parts of the two carriage pillars 2 can dock with the other fixed track beam 3 after they are close to each other. The second driving device can be installed on a foundation, or installed at the bottom of the fixed track beam 3. The second driving device can drive the two carriage mechanisms to move at the same time, so that they move away from or closer to each other. The second driving device can drive the carriage mechanisms to move in a variety of ways, such as including multiple power drive modules, one or more power drive modules respectively drive the carriage pillar 2 of a carriage mechanism to move, and the second driving device can also include a servo motor and a screw mechanism, which drives the bidirectional screw of the screw mechanism to rotate through the servo motor. Two screw nuts are arranged on the bidirectional screw, and each screw nut is respectively connected to one of the carriage pillars 2, and each of the carriage pillars 2 The upper part is provided with a track part, so that after the two vehicle frame pillars 2 are close to each other, each track part is docked with the lifting track beam 7 and the other fixed track beam 3. Since the lifting track beam 7 is also docked with one of the fixed track beams 3, the support platform can be docked with both fixed track beams 3, so that the straddle-type monorail vehicle can travel on the support platform. The "docking" of the present invention means that the alignment does not affect the travel of the straddle-type monorail vehicle. The two docked objects can be in direct contact, and there can be a certain distance between them. The second lifting drive mechanism is installed on the vehicle frame pillar 2 and the vehicle frame block 12 is installed on the second lifting drive mechanism to drive the vehicle body to rise and fall.

The connecting rod is hinged at one end, and the other end of the connecting rod is hinged on the base 11 through a third hinge shaft. The power mechanism is installed on the base 11 or the trolley support pillar 2 to drive the slider 10 to move up and down, thereby driving these auxiliary support rods 8 to shrink or expand. When these auxiliary support rods 8 are expanded, the lower ends can fall on the foundation to assist in supporting the vehicle body and limit the position, so that the trolley mechanism will not move when supporting the vehicle body; when these auxiliary support rods 8 are retracted, the lower ends of the auxiliary support rods 8 leave the foundation, and the frame can move by rolling the bottom wheels.

[0033] Furthermore, the second lifting drive mechanism is installed inside the trolley support column 2, the trolley block 12 is installed on the top of the trolley support column 2, and the top of the trolley support column 2 is provided with a groove serving as a moving channel of the trolley block 12.

[0034] Furthermore, the bogie lifting platform 1 is also provided with a distance measuring sensor for obtaining the position of the bogie lifting platform 1 on the platform guide rail 4. A reference plate can be set on the foundation. By obtaining the distance between the distance measuring sensor and the reference plate, the controller can control the displacement of the bogie platform.

[0035] Furthermore, the platform is also provided with a distance measuring sensor for obtaining the position of the platform, and a reference plate may be provided on the foundation.

The positioning block can extend into the positioning hole after the lifting track beam moves to a position where it docks with one of the fixed track beams, thereby preventing the bogie lifting platform 1 from shaking. The positioning block preferably adopts a square structure.

[0038] In the present invention, the process of separating the bogie and the car body of the straddle-type monorail vehicle is mainly realized by the bogie lifting platform 1 and the car-raising platform. Before separation, the operating bogie lifting platform 1 and the car-raising platform are moved to the position where they are docked with the fixed track beam 3, the lifting track beam 7 is lifted to dock with the fixed track beam 3, the two car-raising pillars 2 of the car-raising mechanism are close to each other and dock with the fixed track beam 3, and then the straddle-type monorail vehicle enters the separation station; when the separation starts, after the bogie is unloaded and the two car-raising pillars 2 are away from each other, the car-raising block 12 on the top of the car-raising pillar 2 is raised through the second lifting drive mechanism inside, and the car-raising block 12 contacts the car-raising point at the bottom of the car body, and the car-raising block 12 can lift the car body, and the bogie lifting platform 1 and the car-raising platform are respectively moved to the two sides of the fixed track beam 3 to complete the separation. Separation of the bogie from the car body; when the bogie is separated from the car body, the transporter carries away the bogie and the car body, the bogie lifting platform 1 can be moved to the separation station along the platform guide rail 4, and the car-lifting mechanism can also be moved to the separation station under the drive of the second drive device, and the car-lifting track surface 9 on the car-lifting support 2 is embedded between the two fixed track beams 3, so that the car-lifting support 2 is docked with the fixed track beam 3, and the next round of bogie separation operation is started. In this way, the maintenance operation of the subsequent straddle-type monorail vehicle will not need to wait because the body of the previous straddle-type monorail vehicle occupies the separation station, thereby improving the efficiency of the overall overhaul and maintenance of the straddle-type monorail vehicle equipment.

[0039] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
