A removable gripping device for a container has two clamp-forming members which are mounted to a gripping body, one of which can move longitudinally between an open position and a closed position; movement elements which are designed to move the aforementioned mobile member; and actuation devices which can move in relation to the gripping body. The above-mentioned actuation devices are mounted so as to move longitudinally between a rest position and an actuation position, whereby the actuation devices cause a lever to move from the retracted position to the deployed position thereof.

The invention relates to a suspension type coal bunker damping structure improving heat-engine plant main workshop antivibration performance; the suspension type coal bunker damping structure comprises suspension rods, a steel coal bunker, coal bunker beams, frame beams, frame columns, springs and dampers; the suspension rods are connected with the steel coal bunker and the coal bunker beams, and used for bearing the steel coal bunker gravity and providing swing rigidity; the springs are connected with the steel coal bunker and frame columns in the horizontal surface, and the elastic rigidity of the springs is reasonably designed, so a vibration period of the system formed by the springs, suspension rods and the steel coal bunker can be similar to that of the main workshop structure under major vibration effect, thus realizing frequency modulation function of the suspension type coal bunker; the dampers are connected with the steel coal bunker and the frame columns in the horizontal surface, and can provide large damping force when the steel coal bunker and the frame columns relatively move, thus limiting motion amplitude of the suspension type coal bunker, and improving structure additional damping. The suspension type coal bunker damping structure can be applied to a newly built heat-engine plant main workshop structure or antivibration reinforcement of a conventional heat-engine plant main workshop structure.

In an oscillation type linear actuator for reciprocally moving a plurality of moving members held in parallel with each other in a predetermined direction owing to electromagnetic action between a stator and them, two moving members reciprocally moving in opposite phases with each other are coupled by a coupling member having spring function, and a non-displacing portion of a plate spring portion of the coupling member which is not displaced substantially is restricted by a stopper. Even when an external force is applied to one of two moving members reciprocally moving in the opposite phases each other, motion of the other moving member is transmitted to the moving member via the coupling member, so that reduction of amplitude of the moving member to which the external force is applied can be restricted, and a balance of amplitudes of two moving members is maintained. Furthermore, since a component having the plate spring portion is used as the coupling member, it is possible to downsize the oscillation type linear actuator.

The invention relates to a self-correction platform for a camera. The self-correction platform for the camera comprises a circular ring-shaped outer fixing ring fixed onto an outer moving device, an inner fixing ring connected into the outer fixing ring through two rotary shaft assemblies and capable of turning over in the vertical direction, and a connecting table connected into the inner fixingring through two rotary shaft assemblies and capable of turning over in the horizontal direction. A connecting rod perpendicular to a plane on which the outer fixing ring is located is fixedly connected under the connecting table; and the camera is connected under the connecting rod. According to the device, through structurally arranging the rotary shaft assemblies, when the outer fixing ring andthe inner fixing ring as well as the inner fixing ring and the camera move in the horizontal direction and the vertical direction, a spring can absorb external forces moving in the directions; and through arranging rotary plates and oil in a first shell, damping movement can be realized, and rotating forces in the two horizontal and vertical directions realize rotating through damping, so that the movement ranges in the two directions are further reduced.

A method for controlling a spinning cycle of a washing machine, the method includes accelerating a drum up to a first speed at which the laundry items essentially lie firmly against the wall of the drum, detecting a movement of the detergent solution tub in at least one direction for at least one predetermined period during the rotation of the drum at a speed that is equal to or greater than the first speed, determining an amplitude of the movement for the recorded direction, determining further movement amplitudes for known or detected speeds during the predetermined period, determining a change in the movement amplitude over the speed, and controlling the spinning cycle as a function of the change of the movement amplitude.

The invention discloses a double-layer underwater production supporting floating barrel and installation and recycling methods thereof. The floating barrel comprises an outer floating barrel body and an inner floating barrel body, wherein the inner floating barrel body is nested in the outer floating barrel body. The outer floating barrel body is used for providing tension force of mooring cables, the inner floating barrel body is used for providing top tension force required by a rigid vertical pipe, accordingly, the double-layer floating barrel can conveniently and separately provide the top tension force required by the rigid vertical pipe and the mooring cables, and by applying the double-layer floating barrel in an ultra-deep ocean oil-gas project development system, the requirement for practical project application can be met. The perpendicular movement and stress of the rigid vertical pipe and the outer floating barrel body are decoupled, so that the stress and movement amplitude of the rigid vertical pipe are reduced, and the strength and fatigue performance of the rigid vertical pipe can be improved advantageously. The outer floating barrel body is moored on a seabed through the four mooring cables, when any one of the cables breaks off and fails, the other three cables can still maintain stability of the outer floating barrel body, and safety of the oil-gas development system is ensured.
