Description

Technical Field

[0001] This utility model relates to the field of crane attachment frames, specifically a clamping device for a tower crane attachment frame. Background Technology

[0002] Tower cranes, as indispensable large-scale equipment in modern construction, are widely used in the construction of multi-story and high-rise buildings, undertaking the heavy responsibility of vertical material transportation and component installation. Tower cranes mainly consist of a metal structure, a working mechanism, and an electrical system. As building height increases, tower cranes need to be fixed to the main building structure via attachment frames to ensure their stability and safety.

[0003] Existing tower crane attachment frame clamping devices typically use bolt fixing, which has obvious drawbacks: due to the large size and weight of the attachment frame, bolt fixing cannot guarantee sufficient stability, especially when faced with external forces such as strong winds and vibrations, the clamping device is prone to loosening, thus causing serious safety hazards.

[0007] As a further embodiment of this utility model: the inner frame of the outer frame is hinged with hinge component one and hinge component two at opposite corners, and a cylinder is installed between hinge component one and hinge component two.

[0008] As a further embodiment of this utility model: the number of outer frames is two sets, the lower part of the outer wall of the upper outer frame is fixedly connected with a lock hole block, and the lower part of the outer wall of the lower outer frame is installed with a locking pin. The lock hole block and the locking pin are fixedly connected by bolts.

[0009] As a further embodiment of this utility model: the upper and lower parts of the inner frame of the outer frame are welded with connecting rods, the connecting rods are inclined, and the outer wall of the outer frame is provided with a building wall.

[0010] As a further embodiment of this utility model: a ladder is installed on the inner frame of the inner frame, the upper part of the ladder is welded to the upper left part of the inner frame of the inner frame, and the lower part of the ladder is welded to the front part of the inner frame of the inner frame.

[0011] As a further embodiment of this utility model: the number of the protective frames is two sets, the number of the connecting plates is two sets, and the two sets of protective frames and the two sets of connecting plates are fixedly connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this utility model, triangular seats installed at the four corners of the inner wall of the outer frame are used to fix the pulleys. The pulleys contact the outer frame of the inner frame, and under the pull of the lifting unit, the outer frame slides on the outer frame of the inner frame. When the outer frame slides to the specified position, the operation of the cylinder pushes the hinge part 2, which is hinged to the inner frame of the outer frame, and the hinge part 1, which is hinged to the inner frame of the outer frame, to retract, applying a pulling force to the outer frame and thus securing the outer frame to the outer frame of the inner frame. Its structure is more optimized and its design is more reasonable. Attached Figure Description
