Construction platform hanger with clear stress and adjustable hanging point

Abstract

The invention provides a construction platform hanger with clear stress and an adjustable hanging point, and belongs to the field of hoisting machinery. The construction platform hanger provided by the invention is composed of cross beams, longerons, upper slings, lower slings and shackles, wherein each cross beam is composed of two segments of beams arranged at an interval and a supplementary adjusting cross beam arranged between corresponding inner ends thereof, each longeron is composed of two segments of beams arranged at an interval and a supplementary adjusting longeron arranged between corresponding inner ends thereof, an upper hanging shaft and a lower hanging shaft are arranged at the two ends of the cross beam, an axle hole is formed in each of the two ends of the longeron; the pair of cross beams is arranged in parallel, the lower hanging shafts at the two ends of the pair of cross beams are respectively hinged with the axle holes at the two ends of the pair of longerons to form a rectangular beam frame, the upper slings are connected with a crane lifting hook by bypassing the four upper hanging shafts of the rectangular beam frame, the lower slings are respectively connected with the shackles by passing the four lower hanging shafts, the shackles are correspondingly connected with the lifting lug plate of the construction platform, during lifting work, the cross beams or the longerons are mainly applied with a force in the axial direction, the stress of the hanger is clear, the working state is stable and reliable, and the stability and safety of the crane are improved.

Description

technical field [0001] The invention is a construction platform spreader with clear force and adjustable lifting point, which belongs to the field of hoisting machinery, and in particular relates to offshore hoisting construction equipment. Background technique [0002] With the continuous development of science and technology and the continuous strengthening of the design capabilities of crane companies, large-scale jib cranes have become the main force in offshore engineering construction. To complete the construction of the project, the crane needs a set of special spreader and rigging to connect the crane hook and the object to be hoisted. At present, the structure of the widely used spreader is relatively complicated, and the spreader components generally have to bear axial stress, bending stress, shear stress, etc., and the force of the spreader often depends on the connection between the lifted object and the spreader With the diversification of the hoisting size of ...

Problems solved by technology

At present, the structure of the widely used spreader is relatively complicated, and the spreader components generally have to bear axial stress, bending stress, shear stress, etc., and the force of the spreader often depends on the connection between the lifted object and the spreader With the diversification of the hoisting size of the hoisted object, the force of the spreader system is also different.
