The present application relates to a large material rail type automatic handling equipment, which is carried by a track to run, can realize the carrying, fixing and loading and unloading of materials, has an automatic control function, can realize the cooperation with hoisting equipment, complete the loading and unloading of large materials on the handling equipment, and complete the material transmission between the automatic transfer equipment through the locking and unlocking of the locking mechanism and the docking of the docking mechanism.

This invention belongs to the field of metal casting equipment technology and discloses an extra-large centrifugal casting mold, including a base assembly; the lower end of a mold assembly is fixedly connected to the base assembly; the upper cover assembly is connected to the upper end of the mold assembly, and the two together form the forming cavity of the casting; the upper cover assembly has a pouring hole; it also includes a rigid constraint frame, which includes multiple longitudinal load-bearing members evenly distributed along the circumference, the lower end of each longitudinal load-bearing member is fixedly connected to the base assembly, and the inner sides of each longitudinal load-bearing member surround and are fixed to the outer circumferential surface of the mold assembly; it also includes multiple sets of thermally actuated clamping mechanisms, which are correspondingly installed on the upper part of each longitudinal load-bearing member; each thermally actuated clamping mechanism includes a driving member arranged radially along the mold and a pressure member connected to the inner end of the driving member; this invention has good rigidity, can effectively adapt to thermal deformation, and has accurate positioning, reliable sealing, and the core vulnerable parts can be quickly replaced.

The utility model relates to the technical field of door control hardware, disclose adjustable door closer device of steel clean door, including door frame, door closer shell, the inside of door closer shell is provided with round hole, the left side inside fixedly connected with buffer spring of door closer shell, the other end fixed mounting of buffer spring has plunger, the outer surface fixed mounting of plunger has stroke sealing ring, the right side outer surface fixed mounting of plunger has rack, the round hole upper end contact connection of door closer shell has limit ring, the inner surface rotationally connected with pinion of limit ring, the lower end fixedly connected with gear of pinion, the rack is engaged with gear connection. In the utility model, through gear rotation drive two plunger left and right movement, drive the contraction of buffer spring, and the liquid in cavity will flow to left and right cavity because of the reason of air pressure, and then realize the switch cooperation of clean door.

The application discloses a preparation method of a TBC back contact solar cell multi-tunneling oxide layer, utilizes a multi-temperature zone LPCVD device, realizes whole-process precise temperature control from pretreatment to deposition and then to annealing, slow cooling transition and low-temperature interval of the whole deposition process, greatly reduces thermal stress and is suitable for sheeting production; through decomposing the deposition process into three sub-steps and accurately designing pressure environment, gas type, flow and duration of each sub-step, "programmable" growth of the structure, composition and doping concentration of the oxide layer from an interface to a bulk phase and then to a surface layer is realized; this is the core of realizing a high-performance multi-layer tunneling structure, high quality and high uniformity under low temperature; precise cooperation of temperature and gas sequence ensures that even under low temperature, a high-quality oxide layer with density, uniformity and low interface state density can be obtained, and a relatively wide process window and good repeatability are realized.
