DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of an insulating buffer plate replacement vehicle provided in an embodiment of the present invention, Figure 2 for Figure 1 Schematic diagram of the structure of the linear module.

[0025] In the first specific embodiment, the insulating buffer pad replacement vehicle provided by the present invention includes a vehicle body 4 and a track 8 arranged on the lower side of the vehicle body 4, a linear module 5 and a track lifting device 6 slidingly connected to the track 8 are provided on the lower side of the track 8, and a pad replacement device 9 is provided on the lower side of the linear module 5.

[0026] In this embodiment, the car body 4 moves along the rails on the ground, the track 8 is on the lower side of the car body 4 in the same direction as the rails, both ends of the straight track 8 are fixedly connected to the car body 4, the linear module 5 and the track lifting device 6 slidingly connected to the track 8 move along the track 8, the track lifting device 6 moves to the rail to be lifted to perform the rail lifting operation, further, the linear module 5 drives the pad replacement device 9 on its lower side to move to the lifted rail to replace the insulating buffer pad.

[0027] The track 8 serves as a connecting member and a moving track for the linear module 5 and the track-lifting device 6, so that the linear module 5 and the track-lifting device 6 can be adjusted and fixed on the lower side of the vehicle body 4. The linear module 5 and the track-lifting device 6 can be respectively provided with a driving device for providing power for movement along the track 8, or a driving device connected to the linear module 5 and the track-lifting device 6 and providing power can be provided on the track 8, and the driving device includes but is not limited to an electrically driven electric cylinder or a hydraulically driven oil cylinder. Similarly, the track-lifting device 6 includes a manipulator or a clamp that can descend and grab the rail and then rise, and the track-lifting device 6 also includes a driving device that drives the manipulator or the clamp to achieve movement.

[0028] Compared with the manual rail lifting and manual replacement of insulating buffer pads in the prior art, the insulating buffer pad replacement vehicle has a high degree of automation. By automatically replacing the insulating buffer pads, the replacement efficiency is effectively improved, replacing the manual operation method and reducing labor costs.

[0029] In order to achieve better technical effects, an oiling device 10 is also provided on the lower side of the linear module 5 for oiling the sleeper bolts to prevent rust.

[0030] In this embodiment, the rail fasteners and the rail sleeper bolts are combined to fix the rails. In order to extend the service life of the rails, the rail sleeper bolts on both sides of the rails are oiled. Specifically, after the track lifting device 6 lifts the rails, the oiling device 10 performs an oiling operation and applies oil to the rail sleeper bolts to prevent rust. A layer of oil is attached to the surface of the rail sleeper bolts, which has stronger corrosion resistance in the natural environment. The oiling device 10 includes an oil tank storing oil and a nozzle or a brush connected to the oil tank and applied oil to the rail sleeper bolts.

[0031] In addition, the vehicle body 4 is provided with an electrical control system 13 connected to the linear module 5, the track lifting device 6 and the oiling device 10. The electrical control system 13 is equivalent to the main controller of the insulating buffer pad replacement vehicle, and intelligently manages and controls the movement and operation of various components provided on the vehicle body 4.

[0032] In order to achieve better technical effects, a driver's cab 3 is provided at one end of the vehicle body 4 , and a bogie 2 is provided at the lower side of the driver's cab 3 .

[0033] A power system 11 and a brake system 12 connected to an electrical control system 13 are arranged on the vehicle body 4. The electrical control system 13 is provided with an interactive control panel in the driver's cab 3. The electrical control system 13 controls the power system 11 to provide power for the vehicle to move forward or controls the brake system 12 to provide braking force for stopping the vehicle.

[0034] Exemplarily, the power system 11 can be a diesel generator set using a diesel power generation mode, a power grid-connected power generation set using a power grid-connected power generation mode, or a dual-power mode combining the diesel power generation mode and the power grid-connected power generation mode. It should be noted that the diesel generator set and the power grid-connected power generation set are not the core improvements of the present invention. Please refer to the prior art and will not be described here.

[0035] For better technical effect, the bogie 2 is a power bogie, and the power bogie is provided with a traction motor, so that the insulating buffer plate replacement vehicle has walking 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.

[0036] For better technical effect, the lower side of the cab 3 is also provided with an initial positioning image processing system 1 connected to the electrical control system 13, and the lower side of the linear module 5 is also provided with a fine positioning image processing system 7 connected to the electrical control system 13. In this embodiment, the initial positioning image processing system 1 initially locates the position of the sleeper bolts on the ground rail, the electrical control system 13 roughly adjusts according to the initial positioning to control the linear module 5 to move to the initial position along the track 8, the fine positioning image processing system 7 accurately locates the position of the sleeper bolts, the electrical control system 13 controls the linear module 5 and the track lifting device 6 to reach the designated position according to the precise positioning fine adjustment, and the track lifting device 6 performs the rail lifting operation, the oiling device 10 performs the oiling operation, and the pad replacement device 9 performs the replacement operation.

[0037] Specifically, because the vehicle may move onto a curved rail, the offset of each position is different. The initial positioning image processing system 1 can only perform initial positioning and cannot be used for accurate positioning of multiple operations. 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 bolt to the electrical control system 13. The electrical control system 13 controls the linear module 5 and the track lifting device 6 to move to the vicinity of the sleeper bolt, and then uses the precise positioning image processing system 7 on the lower side of the linear module 5 to accurately position the sleeper bolt. The insulating buffer plate replacement vehicle uses image processing technology to cooperate with the automatic replacement of insulating buffer plates, which improves the intelligence of the vehicle.

[0038] In addition, the pad replacement device 9 includes a pad box 15, a suction cup 16, and a manipulator. The pad box 15 is used to place the insulating buffer pads to be replaced at the rail. The suction cup 16 absorbs the insulating buffer pads from the pad box 15 and places them on the positioning platform 14. The manipulator then grabs the insulating buffer pads from the positioning platform 14 and moves them to the rail for replacement. The pad replacement device 9 and the oiling device 10 work all the time, and the suction cup 16 works intermittently to ensure that there are a sufficient number of insulating buffer pads on the positioning platform 14 for the pad replacement device 9 to grab.

[0039] In another specific embodiment, there are multiple linear modules 5, and the multiple linear modules 5 are arranged along the track 8. The lower side of each linear module 5 is provided with multiple pad replacement devices 9, oiling devices 10 and precise positioning image processing systems 7 corresponding to the rails.

[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 13. The electrical control system 13 performs intelligent division of labor, and the electrical control system 13 controls multiple linear modules 5 and the track-lifting device 6 to move to the vicinity of the corresponding positions of the sleeper bolts, and then uses the precise positioning image processing system 7 on the lower side of the multiple linear modules 5 to accurately position the sleeper bolts at the corresponding positions. Further, the electrical control system 13 controls the track-lifting device 6 to perform the rail-lifting operation, the oiling device 10 to perform the oiling operation, and the pad replacement device 9 to perform the replacement operation in sequence according to the precise positioning. After the replacement operation is completed, the track-lifting device 6 moves in the opposite direction and puts the lifted rails back to their original positions, and the vehicle continues to move forward, completing an operation cycle.

Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea.
