5results about How to "Will not affect normal driving" patented technology

The application provides a motor dynamic control method, device, equipment and vehicle, which can determine different induced electromotive force voltages according to different operation parameters of a target motor, determine a maximum value of the induced electromotive force voltage allowed to appear in the current relay state, and further determine the maximum allowed speed of the target motor. Since the induced electromotive force voltage is constantly changing, the maximum allowed speed is also changing. The switching of the protection mode is performed according to the maximum allowed speed, the dynamic switching is realized, the safety of the motor is ensured, the maximum allowed speed corresponds to a higher vehicle speed, and the normal driving of the vehicle is not affected by limiting the vehicle speed according to the maximum allowed speed.

This invention belongs to the field of AGV (Automated Guided Vehicle), and particularly relates to an automatic charging system and charging method for AGV transport vehicles; it includes a control console, a circular path, multiple AGV transport vehicles arranged on the circular path, and at least one charging device arranged on one side of the circular path. Each AGV transport vehicle travels at intervals along the circular path, and each AGV transport vehicle interacts with the control console; the charging device also interacts with the control console; when any AGV transport vehicle detects that its own power level is lower than a first preset power level, the control console controls the AGV transport vehicle to travel along the circular path to the charging device for positioning and charging. The control console is used to detect in real time whether the AGV transport vehicle adjacent to the charging AGV transport vehicle meets the preset conditions. If so, the control console controls the first charging device to stop charging, and the first AGV transport vehicle travels forward along the circular path.

The utility model discloses a folding luggage rack, which relates to the technical field of luggage racks and comprises a fixing frame, a first screw is rotatably mounted in the middle of the fixing frame, a first fixing plate is mounted on the outer surface of the first screw in a threaded manner, and two symmetrically distributed second fixing blocks are fixedly mounted on the lower portion of one side of the first fixing plate. A second fixing plate is fixedly installed on the outer surface of the rotating shaft, a first fixing block is fixedly installed on the lower portion of one side of the first fixing plate, and a worm is rotatably installed in the middle of the first fixing block; the luggage rack mounted at the tail of a vehicle can be folded and adjusted in height, the luggage rack is folded when not used, so that the luggage rack is vertically arranged at the rear, normal driving is not affected, and luggage can be placed at the tail more conveniently through height adjustment.

The invention provides a ship body protection device for a ship, and relates to the technical field of ship body protection, the ship body protection device comprises a ship bottom, an anti-collision column is fixed on the surface of the bottommost part of the ship bottom, an anti-collision assembly is arranged in the anti-collision column, the anti-collision assembly comprises a storage frame, and a rolling shaft is rotatably mounted in the storage frame through a bearing and a torsion spring; a plurality of air bags are wound on the winding shaft, every two adjacent air bags are fixedly connected, the air bag at the bottommost part of the storage frame is fixed to the interior of the anti-collision column, and a driving assembly is arranged at the top of the ship bottom slope. The anti-collision assembly can achieve the anti-collision effect on the two sides of the ship, the anti-collision assembly can be opened when used and closed when not used, normal traveling and the size of the ship cannot be affected, the anti-collision assembly can clean the slope of the ship when unfolded, and manual cleaning of algae and shells is replaced.

The present invention discloses a coal yard structure of a remote-controlled bridge crane, wherein a concrete bottom plate is fixedly arranged at the bottom of the pit, a concrete wall plate is fixedly arranged at the pit wall, a strip platform is fixedly arranged on the top surface of the concrete bottom plate, a plurality of partition wall plates are evenly distributed between the strip platform and the concrete wall plate, the partition wall plates divide the foundation pit on both sides of the strip platform into a plurality of coal storage pits, the pit bottom surface and the pit wall surface of the coal storage pit are covered with bottom steel plates and side steel plates, a vibrator is arranged at the center of the pit bottom of the coal storage pit and below the bottom steel plate, a side wall is arranged on the top surface of the concrete wall plate, and door openings are arranged at the positions of the strip platforms respectively, a bridge is spanned across the upper part between the side walls, a trolley is arranged on the bridge, a digging claw is arranged at the bottom of the trolley, a water spray pipe A is arranged at the bottom of the trolley, a loading and unloading boss is arranged on the side wall of the strip platform facing the coal storage pit, and a water spray pipe B is arranged on the unloading platform. As can be seen from the above structure, the coal yard structure of the remote-controlled bridge crane of the present invention can ensure the efficiency of the digging claw in digging coal each time.
