The invention relates to the technical field of mechanical arms, and particularly discloses an airport high-altitude lamp maintenance mechanical arm which comprises an adjustable supporting arm, a first clamp and a second clamp, and the second clamp comprises a beam frame and two self-adaptive clamping mechanisms; a guide rod and a main shaft are fixed on the beam frame, and two external thread sections are arranged on the main shaft; the self-adaptive clamping mechanism comprises a sliding arm and a telescopic rod; one end of the sliding arm is provided with a guide hole and an internal thread sleeve, a gear is fixed to the internal thread sleeve, and a first clamping block is fixed to the other end of the sliding arm. The telescopic rod is slidably fixed to the sliding arm, one end of the telescopic rod is a rack part meshed with the gear, and a second clamping block is fixed to the other end of the telescopic rod; the guide rod is sleeved with the guide hole, and the main shaft is sleeved with the inner threaded sleeve which is matched with the outer threaded section. When a high-altitude lamp is disassembled and maintained, the mechanical arm for maintaining the high-altitude lamp in the airport can temporarily fix a lamp body, the operation efficiency and safety are remarkably improved, and the mechanical arm is small, compact, high in flexibility and convenient to carry.

The utility model discloses a locker for a locomotive, which comprises a locker body, a luggage case, a plurality of storage cavities and a locker door, the luggage case is arranged at the top of the locker body and used for storing luggage articles of trainmen, the storage cavities are arranged on the locker body and used for storing electric appliances or other onboard articles, and the locker door is arranged on the locker body. One end of the storage cavity is an open end so that articles can be conveniently stored and taken out, the cabinet door is rotationally arranged in the storage cavity, the articles in the storage cavity are protected, the articles can be prevented from falling off in the running process, meanwhile, the articles in the storage cavity can be shielded, and the locomotive is neater and more attractive. The cabinet door can slide in the storage cavity in the open state, the cabinet door slides into the storage cavity after being opened, the occupied space can be reduced, and meanwhile collision between the cabinet door and a steward can be avoided.

The present invention relates to the field of mechanical arm technology, and specifically discloses a mechanical arm for repairing high-altitude lighting fixtures at an airport, comprising an adjustable support arm, a first clamp and a second clamp, wherein the second clamp comprises a beam frame and two adaptive clamping mechanisms; a guide rod and a main shaft are fixed on the beam frame, and two external thread sections are arranged on the main shaft; the adaptive clamping mechanism comprises a sliding arm and a telescopic rod; a guide hole and an internal thread sleeve are arranged at one end of the sliding arm, a gear is fixed on the internal thread sleeve, and a first clamping block is fixed at the other end of the sliding arm; the telescopic rod is slidably fixed on the sliding arm, one end of the telescopic rod is a rack portion, the rack portion is meshed with the gear, and a second clamping block is fixed at the other end of the telescopic rod; the guide hole is sleeved on the guide rod, and the internal thread sleeve is sleeved on the main shaft and matched with the external thread section. When disassembling and repairing the high-altitude lighting fixture, the mechanical arm for repairing the high-altitude lighting fixture at the airport can temporarily fix the lamp body, significantly improving the operating efficiency and safety, and it is compact, highly flexible, and easy to carry.

The utility model discloses an adjustable quasi-high-speed camera protection support, which solves the problem that a traditional quasi-high-speed camera is difficult to protect when being aligned with an exposed connecting line of a high-speed camera. The device specifically comprises a mounting seat, a movable joint, a protective cylinder, a cover plate and protective glass, a first wire passing hole is formed in the middle of the mounting seat; one end of the movable joint is connected with the mounting seat through a vertical rotating shaft, and the other end is connected with one end of the protective cylinder through a transverse rotating shaft; a second threading hole is formed in the middle of the movable joint; a camera mounting cavity is formed in the protective cylinder, and an annular end cover is sleeved with the other end of the protective cylinder; a first annular notch is formed in the annular end cover close to the inner ring; an access hole is formed in the side wall of one side of the protective cylinder; an access cover plate is arranged at the access hole; the cover plate is of an annular structure, and a second annular notch is formed in the cover plate close to the inner ring; the cover plate is mounted at the other end of the protective cylinder, so that the first annular notch and the second annular notch are spliced into an annular mounting groove; and the protective glass is embedded in the annular mounting groove and corresponds to a lens of the quasi-high-speed camera.

The present invention discloses a shallow buried lifting column and a lifting method applied to the shallow buried lifting column, comprising an embedded box, a movable cover plate, a rotating seat, a movable column, a first driving device and a second driving device, wherein the first driving device and the second driving device are both arranged in the embedded box, the top of the embedded box is surrounded by a receiving opening, the rotating seat is installed on the inner side of the embedded box and is fixedly connected to one end of the movable column, the first driving device is used to drive the movable cover plate to reciprocate relative to the embedded box, and the second driving device is used to drive the rotating seat to reciprocate relative to the embedded box. The shallow buried lifting column of the present invention has sufficient lifting height while achieving shallow burial, and can be widely used in various areas with limited surface excavation depth.
