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.

A material storage apparatus for weld coiled wire Including flat trolleys, the flat pusher is provided with a lower disk and an upper disk which are distributed in parallel, the left side of the lowerdisk is fixed with a connecting post connected with the upper disk, the lower disk and the upper disk have equal diameters and are provided with arc-shaped sliding grooves concentric with themselves,The arc-shaped sliding grooves are two and symmetrically distributed before and after, and the corresponding arc-shaped sliding grooves in the lower disk and the upper disk are slidably connected with three upright columns, springs located in the arc-shaped sliding grooves are supported between adjacent upright columns, and the upright columns are fixedly provided with a limiting block positionedas a coiled wire material. The invention can realize the positioning and storing of the stacked coiled wire, avoids tilting and falling of the coiled wire in the moving transportation process, staggered separation, simple and convenient collection of the wire, and has the advantages of compact structure, high automation degree and convenient use.

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.

The invention relates to the technical field of machinery and discloses an anti-overturning device and an engineering machine. The anti-overturning device is used for the engineering machine with legs and comprises a first acquiring unit, a computing unit, a first judging unit and a first processing unit, wherein the first acquiring unit is used for acquiring data of hoisted object weight, arm support length, arm support angle, weight of counter weights, rotation angle and off weight of the engineering machine, the computing unit is in signal connection with the first acquiring unit and used for computing the centre-of-gravity position of the engineering machine according to the data acquired by the first acquiring unit, the first judging unit is in signal connection with the computing unit and used for judging whether the subpoint of the centre-of-gravity position is located within a leg frame or not, and the first processing unit is in signal connection with the first judging unit and used for controlling the engineering machine to lock actions in the dangerous direction when the centre-of-gravity position is located outside the leg frame. Compared with the prior art, the anti-overturning device has the advantages that overturning of the complete machine due to failure in paying sufficient attention to leg alarming information or misoperation by an operator can be avoided, and accordingly heavy economic losses and risks of casualties are reduced beneficially.

The invention discloses a product reset system for an automatic industrial production assembly line. The product reset system comprises a machine frame, wherein a through groove with a forward openingis formed in the machine frame in an up-and-down through manner, and a reset mechanical claw and an induction device are arranged in the through groove; and the reset mechanical claw can clamp a workpiece and reset the workpiece, and the induction device can control starting and stopping of the reset mechanical claw. According to the product reset system for the automatic industrial production assembly line, the reset mechanical claw has the same speed as a conveyor belt, when the mechanical claw and the workpiece are relatively still, the workpiece is clamped, and the mechanical claw is rotated, so that the workpiece is driven to rotate, the orientation of the workpiece is corrected, and the tilting situation of the workpiece is avoided.
