This invention provides a jack fixing frame and a base beam under the frame for lifting and positioning a boiler drum using a steel structure, relating to the field of boiler drum hoisting technology. It includes a base beam under the frame and a jack fixing frame. The base beam is detachably connected to the top of the boiler steel frame body, used to bear the hoisting load of the jack and the boiler drum and transfer it to the boiler steel frame body. The jack fixing frame is installed above the base beam. This invention uses clamping steel beams on both sides of the limiting crossbeam to laterally clamp the boiler steel frame body, and the clamping steel beams of the limiting crossbeam and the clamping bolts to vertically clamp the hoisting longitudinal beam, forming a double fixation. Simultaneously, anti-slip pads are provided at the connection points to effectively prevent displacement and shaking of the base beam during hoisting, significantly improving the stability of the jack and the entire hoisting system, reducing safety hazards, and improving the reliability of the fixation compared to existing simple bolt fixing structures.

The utility model provides a detachable concrete cover plate hoisting structure which comprises a plurality of sleeves pre-buried in a concrete cover plate, a cover sealing assembly or a hoisting assembly is detachably connected in the sleeves, the hoisting assembly comprises a connecting rod and a lasso, one end of the connecting rod is detachably connected with the sleeves, the other end of the connecting rod is fixedly connected with the lasso, and the lasso is fixedly connected with the cover sealing assembly or the hoisting assembly. The lifting requirement of the cover plate is met, the cover sealing assembly can be arranged without dismounting the lifting assembly during lifting, traveling vehicles or pedestrians can conveniently go on the cover plate, and meanwhile the risk that the lifting assembly is artificially damaged is avoided.

This utility model discloses a hoisting device for aluminum profile processing, belonging to the field of aluminum processing technology. Key technical features include a support base with hoisting mechanisms welded to both sides of the top of the support base. A locking mechanism is movably connected to the bottom of the hoisting mechanism. The locking mechanism includes a lifting ring, a connecting rod, a fixing block, a rotating rod, locking half-plates, several mounting holes, and an electromagnet plate. The lifting ring is movably connected to the inner side of the hoisting mechanism. The connecting rod is welded to the bottom of the lifting ring. The fixing block is welded to both sides of the surface of the connecting rod. The rotating rod is rotatably connected to the bottom of the inner side of the fixing block. The locking half-plates are welded to the surface of the rotating rod. The locking mechanism adjusts the opening angle of the two locking half-plates via the rotating rod, adapting to aluminum profiles with different cross-sectional shapes. The inner electromagnet plate generates an adsorption force when energized, which, combined with the anti-slip texture of the rubber buffer pad, provides double protection against shaking and slippage of the profile during hoisting, reducing the risk of falling.

This invention discloses a heavy-duty anti-sway dual-winch synchronous lifting tower crane device and its control method, belonging to the technical field of construction equipment. Addressing the problems of existing tower cranes with single-winch single-lifting structures, such as easy swaying during long load lifting, poor adaptability to non-irregularly shaped loads, low synchronous control accuracy, and insufficient operational stability, this invention's device includes a lifting frame, tower crane boom, a first lifting module, a second lifting module, wire rope, a first winch module, a second winch module, hooks, a fixed platform, and a rotating platform. It is equipped with a dedicated synchronous anti-sway control method, which uses the dual winch modules to coordinate and synchronously wind up and down the rope, achieving traction and sway suppression at both ends of long loads. The winch speed can also be independently adjusted, and the height of the two hooks can be differentiated to adapt to the lifting of non-irregularly shaped loads. This invention combines optimized equipment structure with intelligent synchronous anti-sway control. Components are neatly numbered, and the platform layers do not interfere with each other. It offers stable operation and strong lifting adaptability, suitable for various high-altitude heavy-duty lifting operations in construction, significantly improving lifting stability, operational efficiency, and construction safety.
