Description
Technical Field
[0001] The utility model belongs to the technical field of training sand tables, in particular to a city rail train signal training sand table. Background Art
[0002] Urban rail transit is the backbone of urban public transportation. It is energy-saving, land-saving, has a large capacity, is all-weather, pollution-free (or less pollution) and safe. It is a green and environmentally friendly transportation system, especially suitable for large and medium-sized cities. The "Urban Public Transportation Classification Standard" also clearly states that urban rail transit includes: subway system, light rail system, monorail system, tram, maglev system, automatic guided rail system and urban rapid rail system. In addition, with the development of transportation systems, some other new transportation systems have emerged.
[0003] The patent with publication number CN216053392U discloses a sandbox for training urban rail train signals. The pulling plate is pulled to move the locking rod out of the installation slot, and the threaded rod is driven to rotate by rotating the turntable. When the threaded rod rotates, it drives the outer sleeve to move to the left. While the sleeve moves, the connecting rod drives the active push block to move to the left together. The first spring of the active push block moves left to release the stretching, and the inclined block and the support plate are pulled to move upward together. While the support plate moves up, the first sliding cylinder moves inside the first sliding slot, and then drives the swing plate to swing with the support rod as the center. The swinging of the swing plate causes the second sliding cylinder to move in the sliding hole, pushing the sliding plate to move downward. At this time, the pulling plate is released, and the third spring is released from compression to push the locking rod to extend to the inside of the slot to complete the engagement, thereby achieving the purpose of easy movement and facilitating the use of the user.
[0004] However, when the above device is in use, it is necessary to manually operate the turntable, which is rather laborious. At the same time, due to manual adjustment, it is impossible to ensure the synchronous lifting and lowering of the front and rear sides, which can easily cause the training sand table to tilt, resulting in reduced stability of the equipment. Moreover, the device cannot adjust the angle of the display component. Observers need to move around the device to observe different positions, which is not convenient to use. Utility Model Content
