The present invention relates to mechanical engineering, in particular a suspension bridge casting triangular support bracket block 0, at least one set comprising a support frame comprising side frame is mounted on a horizontal bridge pier body, the support frame further comprises a swash support beam, the upper raker beam of the horizontal stringer is connected to a lower beam sprag connected to a reinforcing plate, the reinforcing beams connected to the bottom surface of the steel sheet, the lower cross member is connected to the latch bar, the pin rod is inserted pier reserved pier body bore, the present invention is simply inserted into the plug rod of pier body latch rod hole to complete the reservation fixing operation sprag lower beam, ease of installation, fewer types of operation, operations and reduce cross each other interference, reduce labor intensity.The present invention installed small technical difficulty, ordinary jobs can be, without special work to optimize the allocation of human resources.In summary, the present invention effectively reduce costs and improve efficiency, safety and more secure.

The invention discloses a chess playing robot. The chess playing robot comprises a chessboard, chess pieces, a body, a large arm, a forearm, a tail-end small hand and a control system, wherein the body comprises a sleeve and a large arm beam fixing plate; the large arm comprises a large arm beam and a first drive motor; the forearm comprises a forearm driving part and a forearm executing part; and the tail-end small hand comprises a tail-end small hand driving part and a tail-end small hand executing part. A method for controlling the chess playing robot comprises the following steps of: before a chess playing process is started, recording names of the chess pieces at all the positions on the current chessboard, and resetting the large arm and the forearm to initial positions; after the chess playing process is started, detecting the variation of positions of all the chess pieces to obtain coordinates of moved chess pieces; calculating a chess playing decision; calculating chess playing coordinates and the rotating angle of the large arm and the forearm, controlling the motor to move to a corresponding pulse, and driving the tail-end small hand by using the motor to place the chess pieces at decision positions; and after all the chess pieces are moved, returning the large arm and the forearm to the initial positions. Motive power of the robot, which is generated by grasping or releasing the chess pieces, is lifting power, so that the chess pieces can be mechanically and automatically grasped; and the chess playing robot has a simple structure and is convenient and practical.

The invention is concerned with a kind of tire crane power supply equipment for port container, relating to wire and cable connecting with power supply transmission system and power supply system to tire crane. The wire and cable set on top of tire crane through fixed frame and the position is higher than the height of container truck. The active sliding-wire conductive equipment on wire and cable connects with them while the sliding-wire conductive equipment connects with lead to the power supply system to tire crane. The system with this structure can load and unload using the power of transmission system, and the movement of the cart of tire crane is without of moving in line and fit to be set on the clearance and space of the port without particular requirement. It is very convenient for changing position of tire crane with simple structure, low cost, easy operation and credible safety to reduce cost and pollute.

The invention relates to a preparation method of rivaroxaban intermediate S-N-glycidyl phthalimide. According to the method, catalytic reaction is carried out by using recoverable aluminum oxide in apreparation process of S-N-glycidyl phthalimide, so that the production cost is reduced, the emission requirement is reduced, the problem that the product quality is affected by a phase transfer catalyst difficultly eliminated is solved, the reaction time is further shortened, the special requirement on equipment caused by the use of potassium tert-butanolate is avoided, the production cost is reduced, and therefore, the preparation method is particularly suitable for industrial production.

A super-hydrophobic and super-oleophobic coating and a preparation method thereof. Deionized water, styrene, acrylic monomers, initiators and divinylbenzene are added to a container, stirred evenly, heated to 40-90° C., and kept at a temperature of 1- 10h to obtain a white St-AA copolymer emulsion; add solvent, orthosilicate and St-AA copolymer emulsion into the container, and stir to obtain a homogeneous emulsion; then add ammonia water to the homogeneous emulsion, stir and heat to 30-80° C. , adding fluorosilicone after heat preservation for 0.5 to 8 hours, and continuing to heat preservation for 0.5 to 8 hours to obtain a superhydrophobic and superoleophobic coating. The invention does not need post-treatment to realize super-amphiphobicity; does not need extreme or environment-unfriendly conditions in the synthesis process, uses water and ethanol as solvents in the preparation, is not easy to pollute the environment, and is suitable for large-scale production. The coating synthesized by the method has good stability, and the storage stability is more than 2 years.
