Abstract: A traveling rail jointing device for a pivot-type suspended monorail multi-way turnout beam includes: a jointing plate, a rotating support seat, a lever and a push-pull assembly. The jointing plate is disposed with a rotation shaft thereon along an extension direction of a plate surface thereof. The rotation shaft is rotatably embedded on the rotating support seat. A first end of the lever is fixed on the jointing plate, and a second end of the lever is connected to the push-pull assembly. The technical solution of the disclosure can realize reliable jointing for pivot-type suspended monorail multi-way turnout beams through a simple structure.

Abstract: An aerial transfer carriage and a control method therefor. The aerial transfer carriage includes: a carriage frame, a spreader, a lifting device and an anti-sway device. The anti-sway device includes two correction winch mechanisms and two correction ropes. The lifting device drives an end of each of the two correction ropes to be reel and unreel. The two correction winch mechanisms respectively drive another end of each of the two correction ropes to be reel and unreel. When it is required to correct a deflection of the spreader, the two opposite ends of the correction rope are wound or unwound respectively, and with the two correction ropes disposed crosswise, the correction rope adjusts a lateral position and a longitudinal position of the spreader during reel and unreel.

Abstract: An auxiliary switching device of pivot-type suspended monorail multi-way turnout system includes: a first driving member, a bracket, a slide block, a slide rail, a second driving member and a switching push head. An action end of the first driving member is connected to the bracket to drive the bracket to move back and forth along a first axial direction. The slide block is disposed on the bracket, and the slide block is slidably connected onto the slide rail. The second driving member is disposed on the bracket. The switching push head is connected to an action end of the second driving member.

Abstract: A method for determining grid cell size in geomechanical modeling of fractured reservoirs including a variation range of mechanical parameters of the reservoir is determined. A three-dimensional fracture discrete network model is established. Mechanical parameters of fracture surface are determined on the basis of fracture surface mechanical test. Equivalent mechanical parameters of models with different sizes are researched by three-cycle method, and size effect and the anisotropy of the mechanical parameters of the fractured reservoir are calculated respectively, and an optimal grid cell size in geomechanical modeling is determined.
