The invention relates to a bag collating and clamping linkage mechanism for three-dimensional packaging bags. The bag collating and clamping linkage mechanism comprises a framework. A cylinder is arranged on the upper portion of the framework, perpendicular linear guide rails are respectively arranged on two sides of the framework, and two driving rods are respectively slidably connected onto the two perpendicular linear guide rails, are in drive connection with a bag clamping mechanism arranged on the framework and are connected with each other by a transverse rod; a lifting frame with a single shifting fork is arranged in the middle of the front of the framework, a lifting frame with double shifting forks is arranged in the middle of the rear of the framework, the lower portion of the lifting frame with the single shifting fork and the lower portion of the lifting frame with the double shifting forks are connected with the upper portion of the transverse rod in an abutted manner, the upper portion of the lifting frame with the single shifting fork and the upper portion of the lifting frame with the double shifting forks are respectively connected with compression springs arranged at the front and the rear of the framework, and the lifting frame with the single shifting fork and the lifting frame with the double shifting forks are jointly in drive connection with a bag collating mechanism arranged on the framework. The bag collating and clamping linkage mechanism has the advantages that power can be saved, a mechanism linkage effect can be realized, the bag collating and clamping linkage mechanism is compact in structure, the packaging speed can be greatly increased, and the production efficiency can be improved.

The invention discloses a ceramic packaging base. This ceramic package base includes an insulating base and a tungsten conductive layer; the tungsten conductive layer is disposed on at least one surface of the insulating base; the insulating base is formed of aluminum nitride ceramics; wherein, the tungsten conductive layer includes W, Al and M, where M represents rare earth elements. The aluminum nitride ceramic package base prepared by the invention has high thermal conductivity, good bonding force of the conductive layer and low wiring resistance. This aluminum nitride ceramic package base is suitable for the sensor field, especially the high-power TOF module package, which not only solves the problem of heat dissipation, but also meets the requirements of the TOF working environment.

The invention discloses SY15MnNiCrMoVNbTi steel. The SY15MnNiCrMoVNbTi steel consists of the following components in percents by mass: 0.16-0.20 of C, 0.20-0.50 of Si, 1.40-1.60 of Mn, smaller than or equal to 0.025 of P, smaller than or equal to 0.025 of S, 1.00-1.20 of Cr, 0.40-0.60 of Mo, 1.30-1.50 of Ni, 0.05-0.10 of V, 0.03-0.06 of Nb, 0.02-0.20 of Ti, smaller than or equal to 0.006 of B and the balance of Fe, wherein the sum is 100%. The invention further discloses a preparing method of the structural component of the SY15MnNiCrMoVNbTi steel. The material and the steel structural component reach mechanical performance meeting design requirements through adjusting alloy elements and adopting a reasonable thermal treatment technology, so that the requirement on the work environment in which the steel structural component is positioned is met; and the performance indexes of the steel structural component, such as strength, rigidity, stability, cold and hot processing moldability and weldability, are improved, and the service life of the steel structural component is prolonged.

The invention relates to a top beam and a hydraulic bracket with the top beam, and belongs to the technical field of coal mine equipment. The top beam is internally provided with a telescopic beam; one end of the top beam is of a box body structure; the other end of the top beam is of a cavity structure; a side protecting mechanism is arranged at the cavity structure; coal falling holes are formed in the bottom of the cavity structure; and a flow-up limiting mechanism is arranged at the telescopic beam. The top beam has the characteristics of stability, high reliability, low equipment repairing expense, good practicability, tight contact with a top plate and long service life.

The invention relates to a pneumatic fluid lifter with an injector. On a pump body, a control console is installed, which is provided with an compressed air inlet, an air admission channel and an installation hole, in which a distribution box is installed. The compressed air enters into the distribution box through a control cover board, is injected into the exhaust port through an injection hole; negative pressure is produced in the pump body to suck out the air in the pump body, the water-sucking one-way valve opens, the water is sucked into the pump from the pump bottom; the float in the pump raises to push the cone of the pneumatic valve to rise, when the water level reaches to the designed height, the cone closes the exhaust port, the compressed air transfers into the press-in pump, the water-suction port closes, the water discharging port opens, the water is pressed out from the pump body. As the pneumatic fluid lifter has no rotary part, compressed air is used to suck and discharge water, and water is sucked and discharged automatically depending upon the water level, so un-attended operation is achieved, labor is saved. The pneumatic fluid lifter is of simple structure, easy to maintain, low cost, and can work normally at low water level. The pneumatic fluid lifter has no electric apparatus, is explosive proof, is applicable for working in pits of coal mines and environment with explosive gas.
