The invention discloses a self-walking gantry lifting device. The self-walking gantry lifting device comprises supporting feet and is characterized in that lifting mechanisms are arranged on the supporting feet and comprise lifting frames and jacking hydraulic telescoping cylinders, the lifting frames are nested into the supporting feet in a U-shaped mode and form a gantry structure with the supporting feet; each supporting foot comprises a frame-type base and a column, self-walking mechanisms are arranged at the lower ends of the columns and comprise driving wheels, driven wheels and diesel generators; adjustable hoisting mechanisms are arranged on the lifting frames and comprise positioning pin hole plates, fixed pulleys and hoisting belts. The self-walking gantry lifting device has the advantages that the design of the adjustable hoisting mechanisms is adopted, so that the device is suitable for hoisting of cylindrical devices and can be used for transporting different diameters of workpieces; the design of the supporting foot structures is adopted, so that the loading-unloading time is saved, and an application range is wide; the design of the self-walking mechanisms is adopted, the device has low the field requirements, has no track installation requirement and is suitable for lots of application scenarios.

The invention discloses a multi-mobile-robot minimum step formation method, and the method comprises the following steps: 1), building a multi-mobile-robot motion model in a complex plane; 2), building a topological graph of a multi-mobile-robot system; 3), solving a complex Laplacian matrix; 4), configuring extreme points of the complex Laplacian matrix; 5), calculating distributed discrete control signals; 6), recording the displacement information and calculating the final position. The method can enable a robot to predict the final position of the robot in a formation in the shortest time, and is of a completely distributed type. The employed information is just the displacement information recorded by the robot, and there is no global coordinate system. The robot still can calculate the target position through the rotating speeds of the left and right wheels or the displacement information recorded by other local coordinate systems. The method efficiently helps the robot calculate the target position of the robot, and provides a feasible solution for the high-efficiency formation of multiple mobile robots.

The invention relates to the field of gates characterized of suspended folding movement, in particular to a suspended folding door with a triangular side link linkage mechanism. The suspended folding door with the triangular side link linkage mechanism comprises a suspended folding door body and the triangular side link linkage mechanism. The suspended folding door body is composed of a door post, a first door leaf and a second door leaf. The first door leaf is installed on the door post through a door shaft seat in a suspended mode. The second door leaf is movably connected with the first door leaf through hinges. The triangular side link linkage mechanism is composed of a triangular side link, a first connecting rod and a second connecting rod. One end of the first connecting rod is connected with a top end of the triangular side link in a rotating mode. One end of the second connecting rod is connected with the other top end of the triangular side link in a rotating mode. The suspended folding door body is connected with the triangular side like linkage mechanism in the mode that the third top end of the triangular side link is connected with the door post in a rotating mode, the other end of the first connecting rod is connected with the first door leaf in a rotating mode, and the other end of the second connecting rod is connected with the second door leaf in a rotating mode. When the first door leaf is rotated, the second door leaf conducts folding movement relative to the first door leaf. The suspended folding door with the triangular side link linkage mechanism is simple, achieves synchronous linkage of the two door leaves, and is free of road surface installation requirement.

In a diagnostic imaging apparatus, a stationary gantry (24) and a rotating gantry (22) are interfaced by a plurality of air bearing elements (40). Lower air bearing elements bear the weight of the rotating gantry (22) which induce air hammering phenomena at a characteristic vibration frequency. To counteract the air hammering, a damping assembly (44) is mounted to at least one lower bearing element (40). The damping assembly (44) includes a damping mass (46) and an elastomeric connector (48) that are tuned to a frequency near the air hammer frequency to absorb the vibrational energy and damp the air hammer vibrations.

The invention relates to a digital liquid level sensor, belonging to the technical field of measurement. The digital liquid level sensor is characterized in that the sensor is an integral throw-in-type digital liquid level sensor with an elastic cavity, the sensor consists of a sensing part, a shell and a transmitter 15, and the sensing part (see attached drawing 1) consists of a rubber molded box 1, a magnetic core 2, a coil 3, a spring 4 and an adjusting screw 5, wherein the rubber molded box 1 is a rubber elastic cavity which can be extended and retracted vertically, and the transmitter 15and the sensing part are installed together. When being used, the digital liquid level sensor is directly thrown into liquid to be detected and is not required to be installed. Moreover, since the sensor outputs pulse digital signals, the sensor can be directly matched with subsequent digital processing circuits such as a computer, a single-chip microcomputer and the like. The digital liquid level sensor has the advantages of low manufacturing cost, simple range adjustment and convenience in use, is suitable for all fields of industry and agriculture and can be used for measuring the liquid level of all kinds of conductive and nonconductive liquid materials.
