Description

Technical Field

[0001] The utility model relates to the technical field of tamping vehicles, in particular to a track shifting and distance measuring device for tamping vehicles. Background Art

[0002] The tamping machine is a large-scale track maintenance machine mainly used for railway line maintenance. It can play a role in railway line repair, speed-up transformation of existing lines and construction of new lines, reducing the workload of operators and extending the service life of the machine. The tamping machine has high operating accuracy and efficiency, and can complete the track leveling, track shifting, ballast tamping and shoulder ballast compaction operations. These operations help ensure that the track direction, left-right level and height and front-back all meet the requirements of the line design standards or line maintenance rules, thereby enhancing the stability and safety of the track and ensuring the safe operation of the train.

[0003] The existing tamping vehicle uses a distance sensor to measure the distance between the distance sensor and the rail surface or the ballast bed, and uses this distance value to determine whether the tamping pick assembly has moved horizontally to prevent the tamping pick from damaging the rail. In actual use, the distance sensor is fixedly installed on the mounting brackets on both sides of the tamping pick assembly with screws. Once damaged, the tamping vehicle needs to suspend operation and wait for the distance sensor to be replaced before it can continue to operate. At the same time, since it is installed with screws, installation and removal take a long time, which undoubtedly increases the downtime of the tamping vehicle and reduces the efficiency of track construction.

[0006] Furthermore, the two lifting assemblies both include an electric push rod, and the electric push rod is fixedly installed on the inner top of the shell. The movable end of the electric push rod is fixedly installed with a mounting seat, and the mounting seat slides in contact with the inner wall of one side of the shell. The inner wall of the shell has a limiting effect on the mounting seat, which can ensure the stability of the movement of the mounting seat.

[0007] Furthermore, the two rotating components each include a motor, and the motor is fixedly mounted on a mounting seat, a rotating block is fixedly connected to the driving end of the motor, two mounting blocks are symmetrically fixedly connected to the outer surface of the rotating block, and the mounting block is fixedly connected to the sealing plate, which can drive the two sealing plates to rotate, thereby realizing the position replacement of the working distance sensor and the spare distance sensor.

[0008] Furthermore, the four electrical signal conversion components all include an interface and a USB plug, and the interface is fixedly embedded on one side of the outer surface of the sealing plate and matches the adjacent working distance sensor and the spare distance sensor, the USB plug is fixedly connected to the fixed plate, the interface is electrically connected to the USB plug, and the USB plug matches the USB interface, and the USB interface is connected to the control device of the tamping vehicle, which is facilitating the reception of signals sent by the working distance sensor and the spare distance sensor.

[0009] Furthermore, the inner bottoms of the two shells are provided with through holes penetrating to the bottoms, and the provision of the through holes facilitates the working distance sensor or the standby distance sensor to extend out of the shells.

[0010] Furthermore, a maintenance cover is buckled on one side of the outer surface of the two shells, which is convenient for replacing a damaged distance sensor.

[0011] Furthermore, both the standby distance sensors and the working distance sensor are laser sensors. Laser sensors are mature existing technologies, and corresponding models can be selected according to actual needs.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the track shifting and distance measuring device for a tamping vehicle, through the arranged shell, lifting assembly, rotating assembly, sealing plate, fixing plate, electrical signal transfer assembly, USB interface and spare distance sensor, can promptly replace the spare distance sensor if the working distance sensor is damaged during the construction of the tamping vehicle, and the time consumed is short. The tamping vehicle does not need to suspend operation for this reason, and the damaged distance sensor can be replaced only after the construction is completed, thus avoiding taking up construction time and improving the efficiency of track shifting construction.
