The invention relates to a safe position-limiting mechanism for an automatic rotary table conveying device. The safe position-limiting mechanism for the automatic rotary table conveying device comprises a stopper arranged on a rotary table roller way, and a pressing plate arranged on a conveying roller way, wherein the stopper comprises two sleeves arranged on a bottom plate of the rotary table roller way; support rods are inserted into the two sleeves; one ends of the two support rods are connected with the bottom plate of the rotary table roller way through springs; the other ends of the twosupport rods are connected with the bottom part of one long strip-shaped stopper block; the top part of the stopper block is located above the rotary table roller way so as to stop a workpiece; the bottom part of the stopper block is connected with one end of a connecting rod; a rolling wheel seat and a rolling wheel are arranged at the other end, penetrating through the bottom plate of the rotary table roller way, of the connecting rod; two sections of inclined surfaces with opposite inclined directions are arranged at the bottom end of the pressing plate; the pressing plate is located on arotation path of the rolling wheel rotating along with the rotary table roller way, so that the rolling wheel contacts one section of the two sections of inclined surfaces and rolls along the inclinedsurface so as to drive the stopper block to move downwards, and the top part of the stopper block is located under the rotary table roller way; and through the elastic acting forces of the springs, the stopper block is reset after the rolling wheel and the pressing plate are separated.

The invention provides a railway vehicle and a window thereof. The window comprises a frame and a window body. The frame comprises an outer frame and vertical bars. The outer frame projects out. The vertical bars are disposed at corners of the outer frame to divide the frame into a plurality of sash frames having blunt included angles. The window body comprises glass members and two retainer plates. The glass members are as many as the sash frames. The glass members are fixed between the frame and the vertical bars or between the vertical bars. The retainer plates are fixed on the upper and lower surfaces of the outer frame respectively. When the window which projects out is in use, objects to be detected right in front of people can be seen through the glass members, the objects to be detected lengthwise along a vehicle body can also be seen, the visual angle is enlarged greatly, and accordingly opening the window or stretching the head out of the window is avoided and using safety is guaranteed.

The invention relates to the technical field of bridge detection, and discloses a crack detection device for double-layer supported bridges. The detection requires personnel to go under the bridge, which poses a threat to the personal safety of the detection personnel, and the efficiency is low, which is not convenient for practical use. It includes the bridge body and the mobile seat. The mobile seat is located above the bridge body. There is a lifting seat on the side, a rectangular hole is opened on one side of the lifting seat, a movable plate is provided on one side of the lifting seat, the movable plate runs through the rectangular hole, and the movable plate and the lifting seat are connected by moving out the movable mechanism; while the crack detector body rotates , The body of the crack detector slides relative to the rotating plate, which can detect different positions at the bottom of the bridge body in an all-round way. The operation steps are simple and convenient, and no personnel are required to go under the bridge for detection, which improves safety.

The invention discloses a portal scaffold, which comprises a frame, a platform mechanism, universal wheels and a fixing mechanism; Angle α, 55°≤α≤75°, the third pole is set parallel to the ground, the adjacent first pole and the second pole are fixedly connected by the third pole to form the door frame A, and the two adjacent first poles pass through the third The bars are fixedly connected to form a door frame B, and two adjacent second bars are fixedly connected by a third bar to form a door frame C. Any two door frames A are parallel to each other, and the door frame B and door frame C form an angle β, 0°≤ β≤55°; in the platform mechanism, the first flat plate, the second flat plate and the third flat plate are respectively hinged to the bracket; in the fixed mechanism, the sliding rod moves up or down to the uppermost or lowermost part The wheels or support bases are in contact with the ground. The invention has a simple structure and is a platform structure, so that the scaffolding is not easy to fall over, and the universal wheel is not easy to roll when in use.

The invention discloses a wind power driving system, and particularly relates to an electric direct-driven type wind power variable-pitch device. The wind power variable-pitch driving system is high in reliability and small in occupied space, and comprises a hub, a variable-pitch bearing outer ring and a variable-pitch bearing inner ring, wherein the variable-pitch outer ring is arranged on the hub; the variable-pitch bearing inner ring is in running fit with the variable-pitch outer ring; the electric direct-driven type wind power variable-pitch device further comprises a linear driving mechanism and a connecting rod; two ends of the linear driving mechanism are fixed on the hub; one end of the connecting rod is hinged to the linear driving mechanism, and the other end of the connecting rod is hinged to the variable-pitch bearing inner ring. The linear motion provided by the linear driving mechanism can be transformed by the connecting rod and a mounting rack to rotation of the variable-pitch bearing inner ring. The whole mechanism is compact and reliable in structure, small in occupied space, low in manufacturing difficulty and low in cost.

The invention relates to a vehicle comprising at least one vehicle door or vehicle panel which forms a first element and a vehicle body which forms a second element. The vehicle door or vehicle panel is attached to the vehicle body in a pivotal manner and can be secured to the vehicle body in the closed state by means of at least one lock which interacts with a closing element. The vehicle also comprises an impact damping arrangement (10, 30, 40, 100-700) for damping impacts between the vehicle body and the vehicle door or vehicle panel when the vehicle door or vehicle panel is being closed. The damping arrangement (10, 30, 40, 100-700) has a damping device that is arranged between the vehicle body and the vehicle door or vehicle panel and has a first movement portion which undergoes damping and a second movement portion which does not undergo damping. The invention is characterized in that the impact damping arrangement (10, 30, 40, 100-700) is designed such that, when the vehicle door or vehicle panel is moved towards the vehicle body, said movement passes through the first movement portion first and then through the second movement portion. The first movement portion is arranged such that the movement along the first movement portion ends when the lock and the closing element come into contact with each other.
