[0023] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a sleeper fastener installation vehicle provided in an embodiment of the present invention.

[0024] In a first specific embodiment, the sleeper fastener installation vehicle provided by the present invention includes a vehicle body 4, a track 11 is provided on the lower side of the vehicle body 4 along the length direction of the vehicle body 4, the track 11 is fixedly connected to the vehicle body 4, a fastener placement system 5 is provided on the lower side of the track 11, the fastener placement system 5 is slidably connected to the track 11, and the fastener placement system 5 includes a linear module or robot for grabbing sleeper fasteners and further installing the grabbed sleeper fasteners on the sleeper bolts of the ground rails.

[0025] In this embodiment, the car body 4 moves on the ground rails along the extension direction of the rails and performs automatic installation of the sleeper fasteners. During the automatic installation process, the fastener placement system 5 slides along the track 11 on the lower side of the car body 4, and can slide along the track 11 to the corresponding sleeper bolt installation position. After the position is adjusted, the fastener placement system 5 controls the linear module or robot to manipulate the grabbing fixture 10 or the manipulator to grab the sleeper fastener, and further installs the grabbed sleeper fastener on the sleeper bolt to complete the automatic installation of the sleeper fastener.

[0026] In addition, the car body 4 is also provided with an electrical control system 17 connected to the fastener placement system 5, and the electrical control system 17 controls the fastener placement system 5 to slide along the track 11 to adjust the relative position relationship between the fastener placement system 5 and the sleeper bolts. As a system responsible for computing and processing in the car body 4, the electrical control system 17 receives information from various systems of the car body 4 and controls each system to perform actions.

[0027] In this embodiment, in order to save layout space, the sleeper fastener installation vehicle is used as a trailer and is towed by other vehicles to perform operations.

[0028] In order to achieve better technical effects, a driver's cab 3 is provided at one end of the car body 4 in the length direction. The driver's cab 3 is fixedly connected to the car body 4. A bogie 2 is provided at the lower side of the driver's cab 3. The car body 4 is also provided with a power system 15 connected to an electrical control system 17 and a braking system 16.

[0029] In this embodiment, the power system 15 drives the vehicle body 4 to move along the ground rails, and the braking system 16 is responsible for the braking of the vehicle body 4, all of which are uniformly controlled by the electrical control system 17. Exemplarily, the power system 15 can be a diesel generator set that uses diesel to generate electricity, or a contact network generator set that uses contact network electricity, or a dual-power mode that combines diesel generation and contact network electricity. It should be noted that the diesel generator set and the contact network generator set do not belong to the core improvement points of the present invention. Please refer to the prior art and will not be repeated here.

[0030] In addition, the bogie 2 is a power bogie, and the power bogie is provided with a traction motor, so that the sleeper fastener installation vehicle has running power. In addition to being driven by an electric motor, the power bogie can also be driven by a hydraulic motor. It should be noted that the power bogie does not belong to the core improvement content of the present invention, please refer to the prior art, and no further description will be given here.

[0031] For better technical effects, a preliminary positioning image processing system 1 connected to the electrical control system 17 is further provided at the lower side of the cab 3, and a fine positioning image processing system 7 connected to the electrical control system 17 is further provided at the lower side of the fastener placement system 5. In this embodiment, the preliminary positioning image processing system 1 preliminarily locates the position of the sleeper bolts on the ground rail, the electrical control system 17 roughly adjusts to control the fastener placement system 5 to move to the preliminary position along the track 11, the fine positioning image processing system 7 accurately locates the position of the sleeper bolts, further fine-tunes, and finally the fastener placement system 5 completes the installation of the sleeper fasteners.

[0032] Specifically, because the vehicle may move onto a curved rail, the offset of each position is different, and the initial positioning image processing system 1 can only be used for initial positioning, and cannot be used for accurate positioning of the installation of the sleeper fasteners. Based on the movement direction of the vehicle body 4, the initial positioning image processing system 1 at the head end of the vehicle body 4 scans both sides of the rail under the vehicle body 4, and transmits the approximate position of the sleeper bolts to the electrical control system 17. The electrical control system 17 controls the fastener placement system 5 to move to the vicinity of the sleeper bolts, and then uses the precise positioning image processing system 7 on the lower side of the fastener placement system 5 to accurately position the sleeper bolts. The sleeper fastener installation vehicle uses image processing technology to cooperate with the installation of sleeper fasteners, which improves the intelligence of the vehicle.

[0033] For better technical effect, a nut pre-tightening device 9 is also provided at the lower side of the fastener placement system 5. In this embodiment, the fastener placement system 5 continues to grab the sleeper fasteners on the conveyor belt 8, and the nut pre-tightening device 9 starts to pre-tighten the nuts of the placed sleeper fasteners to prepare for the subsequent tightening of the nuts after the rails are stretched. A gauge adjustment mechanism 6 is provided at the bottom of the car body 4. Through the data of the two image processing systems, the gauge adjustment mechanism 6 drives the rails to move horizontally, ensuring that the rails are placed in the correct position, which is convenient for the installation of the sleeper fasteners.

[0034] In a specific embodiment, a conveyor belt 8 fixedly connected to the car body 4 is also provided on the lower side of the car body 4, and the conveyor belt 8 is located below the fastener placement system 5. A mounting base is provided on the surface of the conveyor belt 8, and the mounting base is provided with an electromagnet or a permanent magnet for adsorbing and fixing the sleeper fasteners.

[0035] In this embodiment, the sleeper fasteners are placed on the mounting base and maintain a fixed posture on the mounting base under the magnetic adsorption of the electromagnet or permanent magnet. The sleeper fasteners are transported to the fastener placement system 5 by the conveyor belt 8, and the fastener placement system 5 removes the sleeper fasteners from the mounting base, and further installs the sleeper fasteners on the sleeper bolts through subsequent operations.

[0036] In addition, the car body 4 is also provided with a floor for placing the container 13, and the floor is provided with a fastener assembly system 14 for grabbing multiple components for constituting the sleeper fasteners from the container 13 and placing the grabbed components into the mounting base in sequence, and the fastener assembly system 14 is connected to the electrical control system 17.

[0037] In this embodiment, the sleeper fastener is composed of a baffle seat, a gauge baffle, a spring bar, a flat washer and a nut, etc. Each component used to form the sleeper fastener is placed in a corresponding container 13, and multiple containers 13 corresponding to multiple components are placed on the floor of the car body 4. The electrical control system 17 controls the fastener assembly system 14 to grab the components in the corresponding container 13, and put the multiple components into the installation base in the order of forming the sleeper fastener. The multiple components are assembled and fixed on the installation base by magnetic adsorption, and the assembled and fixed sleeper fastener is conveyed by the conveyor belt 8. The fastener assembly system 14 can adopt a linear module or robot setting method similar to the fastener placement system 5, and use a grabbing fixture 10 or a manipulator to realize the grabbing and placement of multiple components.

[0038] In addition, the floor is also provided with a cantilever crane 12, which can lift a container 13 on a railway flat car or platform onto the floor of the sleeper fastener installation vehicle.

[0039] In another specific embodiment, there are multiple fastener placement systems 5 , and the multiple fastener placement systems 5 are arranged along the track 11 .

[0040] In this embodiment, the initial positioning image processing system 1 scans both sides of the rails under the vehicle body 4, and transmits the approximate positions of multiple sleeper bolts to the electrical control system 17. The electrical control system 17 performs intelligent division of labor, and the electrical control system 17 controls multiple fastener placement systems 5 to move to the vicinity of the sleeper bolts at the corresponding positions, and then uses the precise positioning image processing system 7 on the lower side of the multiple fastener placement systems 5 to accurately position the sleeper bolts at the corresponding positions and find the center of the sleeper bolts. Further, the electrical control system 17 controls the linear module or robot of the fastener placement system 5 to reach the top of the sleeper bolts, and the linear module or robot installs the captured sleeper fasteners on the sleeper bolts. When all the sleeper bolts under the vehicle body 4 are installed with sleeper fasteners, the vehicle continues to move forward and completes an operation cycle.
