Description

Tower crane attaches frame clamping device Technical Field The utility model relates to the field of crane attachment frames, in particular to a clamping device for a tower crane attachment frame. Background As a large-scale device which is indispensable in modern building construction, the tower crane is widely applied to the construction of multi-layer and high-rise buildings and bears the weight of vertical transportation of materials and installation of components. The tower crane mainly comprises a metal structure, a working mechanism and an electrical system. Along with the increase of building height, the tower crane needs to be fixed on the main structure of the building through the attaching frame so as to ensure the stability and the safety of the tower crane. The existing tower crane attachment frame clamping device generally adopts a bolt fixing mode, and the bolt fixing mode has the obvious defect that the bolt fixing is difficult to ensure enough stability due to the fact that the whole attachment frame is large and heavy, and particularly when the attachment frame is acted against strong wind, vibration and other external forces, the clamping device is easy to loosen, so that serious potential safety hazards are brought. Disclosure of utility model The utility model aims to provide a clamping device for an attachment frame of a tower crane, which aims to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a tower crane attaches frame clamping device, includes the inner frame, the outer wall of inner frame is provided with outer frame, outer frame is close to inner frame outer wall position fixedly connected with triangle seat, the inner frame wall position fixedly connected with installation clamp of outer frame is kept away from to the triangle seat, the pulley is installed to the one end that the triangle seat was kept away from to the installation clamp, outer wall left and right sides fixedly connected with protection frame of outer frame, the equal fixedly connected with connecting plate in position around the outer wall of outer frame, the top of connecting plate is provided with leading frame, the welding of the inner frame position of leading frame has a scissors branch.
