The invention discloses a horizontal posture adjusting mechanism of a girder transporting vehicle when girders are transported on a curved section transverse slope. The horizontal posture adjusting mechanism comprises a girder transporting vehicle body, a balance support and balance oil cylinders, wherein end supporting frames are arranged at two ends of the girder transporting vehicle body respectively, and the balance support is arranged above the girder transporting vehicle body. The horizontal posture adjusting mechanism has the beneficial effects that the balance oil cylinders at the twoends of the end supporting frames drive the balance support to be dragged and adjusted through hydraulic shafts I, the balance support and precast girders are dynamically adjusted by the balance oil cylinders in real time, and the end supporting frames are overturned and adjusted around a balance hinge, so that the balance support always keeps a horizontal state; on one hand, the postures of the precast girders are guaranteed to be horizontal and the mechanism is quickly and efficiently leveled when the precast girders are transported on different transverse slopes; on the other hand, great stability and safety of the girder transporting vehicle when transporting girders work are guaranteed, the precast girders are prevented from toppling and overturning from the girder transporting vehicle, and meanwhile, the collision loss between the precast girders and the girder transporting vehicle body, the balance support and a turntable is also reduced.

The invention relates to a self-walking carrier, which comprises a carrier body, at least two auxiliary wheels, two power wheels, two connection structures, two motors and a control device, wherein the carrier body is sequentially divided into a front section, a middle section and a rear section according to the advancing direction, and is provided with a bearing part used for bearing articles; the at least two auxiliary wheels are respectively arranged at the front section and the rear section of the carrier body; the surfaces of the two power wheels cling to the ground surface; the two connection mechanisms are respectively connected with the two power wheels and the carrier body so as to make the two power wheels be positioned in the middle section of the carrier body, so each power wheel can get close to or far away from the carrier body reciprocatedly according to a scheduled path; the two motors are arranged on the carrier body so as to respectively drive each power wheel; and the control device is used for respectively controlling the rotating speed and the rotating directions of the two motors, so the carrier body can rotate and turn on site, and can adapt to various pavements to prevent the carrier body from tilting and overturning.

The invention discloses a use method of an intelligent safety infant swimming ring. The intelligent safety infant swimming ring comprises a main floating ring, anti-toppling floating rings, a compressed air ring and a controller, and the controller is provided with an anti-toppling combination switch, a first pressure sensor and a second pressure sensor. In use, due to improper use of children or infants, the intelligent safety infant swimming ring is inclined, when inclination of the intelligent safety infant swimming ring exceeds a set control angle, the anti-toppling combination switch transmits an inclination signal to the controller, then the controller controls corresponding anti-toppling inflation solenoid valves to be opened, the anti-toppling floating rings on one side of the corresponding inclined lower end are inflated through the compressed air ring, the buoyancy of one side of the inclined lower end of the main floating ring is increased, thus continuous inclination of the intelligent safety infant swimming ring is avoided, and inclination and toppling of the intelligent safety infant swimming ring are effectively prevented.
