The utility model relates to the technical field of T-beam formworks, and discloses a prefabricated T-beam walking device and a formwork system.The prefabricated T-beam walking device comprises a plurality of fixing pieces arranged in the longitudinal direction of a T-beam, the fixing pieces are evenly and fixedly connected to the outer side of the top of a left side formwork and the outer side of the top of a right side formwork, and the fixing pieces and steel bars on the top of the T-beam are arranged in a staggered mode in the longitudinal direction of the T-beam; a walking track arranged in the longitudinal direction of the T-beam is connected to the fixing piece, a supporting piece with the top end protruding out of the upper portion of the top steel bar is fixedly connected between the walking track and the fixing piece, a construction platform is connected to the walking track, and a driving mechanism used for driving the construction platform to walk along the walking track is connected to the construction platform. According to the T-beam formwork walking device, the fixing pieces and the supporting pieces are arranged, so that the walking track and the construction platform can be arranged more conveniently, and the problems that in the prior art, when a walking device is arranged on a T-beam formwork, arrangement is inconvenient, the equipment cost is high, and the stability of the walking device is poor are solved.

The utility model discloses a kind of shelf robots, it includes at least two fixed beams and at least two movable beams, also includes walking mechanism and execution mechanism;The walking mechanism can make the movable beam along the fixed beam translational motion;Adjacent movable beam is connected with at least two connecting rods, all movable beam and all connecting rod constitute the frame structure that can be integrally translated relative to the fixed beam;Connecting rod and movable beam are connected by pin shaft to establish rotational connection relationship.The utility model in, frame structure is conducive to the stability of execution mechanism along movable beam walking, and the rotational connection relationship between connecting rod and movable beam is established by pin shaft, so that frame structure has the ability of adaptive deformation on demand, avoid the resistance increase caused by the connection position speed inconsistency of frame body and each fixed beam, avoid affecting the walking precision of walking mechanism.

The invention relates to a main beam orthogonal connecting device of a heavy crane applied to bridge replacement and a construction method thereof, a cross beam walking mechanism frame is clamped below a longitudinal beam, and a cross beam driving mechanism is arranged on the side edge of the cross beam walking mechanism frame and drives a cross beam to move in the length direction of the longitudinal beam clamped in the cross beam walking mechanism frame; the running wheelbase of the heavy crane is changed; the longitudinal beam walking mechanism frame is clamped above the cross beam, a longitudinal beam driving mechanism is arranged on the side edge of the longitudinal beam walking mechanism frame and drives the longitudinal beam to move in the length direction of the cross beam clamped in the longitudinal beam walking mechanism frame, and the hoisting span of the heavy crane is changed; the cross beam walking mechanism frame and the longitudinal beam walking mechanism frame are orthogonally connected; the invention aims to solve the problem that the existing heavy crane cannot realize efficient and safe bridge renewal under complex and changeable working conditions due to the inherent structural form solidification and function singleness restriction.
