The utility model discloses an adjustable unit type transverse floating plate structure, and relates to the technical field of transverse floating plates, the transverse floating plate structure comprises a mounting frame and a movable floating plate, the movable floating plate is movably clamped outside the mounting frame, the rear end of the movable floating plate is open, the mounting frame is mounted on the outer side surface of a wall body, and the movable floating plate is mounted on the outer side surface of the wall body. A window is mounted in the wall body, and the mounting frame is located above the window; the first electric push rod is mounted in the mounting frame, a first through groove is formed in the surface of the front end of the mounting frame and communicates with the interior of the mounting frame, the electric push rod is arranged in the mounting frame, and a telescopic rod at the front end of the electric push rod penetrates through the mounting frame to be connected with the movable floating plate; therefore, the movable floating plate can be driven by the electric push rod to stretch and retract, the stretching and retracting position of the movable floating plate can be adjusted according to actual needs, and the multifunctional requirement is met.

The utility model discloses a trolley support suitable for variable cross section tunnel relates to trolley support technical field, including portal main part, telescopic spare is set up on portal main part, and it includes: the outer tube is axially horizontal and is arranged at the top of portal main part, and both ends are connected with outside, the threaded rod is coaxial and is arranged in the outer tube, and the annular gap is left between the outer wall of threaded rod and the inner wall of outer tube, the threaded cylinder is nested in the annular gap, and its inner wall is in threaded engagement with threaded rod. The utility model with the axial movement of threaded cylinder relative to outer tube in telescopic spare, can accurate regulation trolley support node's geometric size. Since the outer tube and threaded cylinder initial state both ends are flush, and the length is same, through rotating knob, can make telescopic output end's length of protruding according to actual demand change, thereby let same trolley support can match different size's tunnel section, need not for each kind of section alone custom-made trolley support, has greatly promoted the versatility of equipment.
