Wind power hoisting tower crane truss type underframe suitable for all-terrain weak ground pressure and tilt resistance

Abstract

The invention discloses a wind power hoisting tower crane truss type underframe suitable for all-terrain weak ground pressure and tilt resistance, and belongs to the technical field of hoisting machinery. The underframe comprises a cross-shaped underframe body, four inclined supports, four sets of supports and base distance wide-face supporting legs, wherein the cross-shaped underframe body is supported below the bottom of a tower bottom foundation section, the two ends of the four inclined supports are hinged to the upper portion of the tower bottom foundation section and the top face of thecross-shaped underframe body respectively, four sets of supports are supported below the four farthest ends of the cross-shaped underframe body, and each support is combined with the cross-shaped underframe body through a height adjusting type spherical hinge assembly. The underframe can meet the construction requirements of all-terrain geological foundations with low foundation bearing capacity requirements, tilt resistance and simple foundations, can be compatible with the differences of various geological foundations, and has the advantages of being reasonable in stress, light in structure,light in dead-weight, low in construction cost, convenient to mount and dismount, convenient to transfer and transport and convenient to operate, and the wind power hoisting tower crane truss type underframe is especially suitable for being matched with a wind power hoisting tower crane with short construction period and frequent transition.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and more specifically relates to a truss-type underframe for wind power hoisting tower cranes suitable for all-terrain weak ground pressure and anti-tilt, especially suitable for wind power hoisting tower cranes with short construction period and frequent transitions . Background technique [0002] The self-erecting tower crane is that the upper part of the tower crane stands on the ground after being connected with the underframe structure, and transmits the load to the ground foundation. ground connection. The pre-buried underframe has low cost and low cost, but it cannot be reused, and it is difficult to disassemble. It is generally suitable for occasions with long construction period and infrequent transfer of tower cranes. The ground-anchored or ballast-type underframe generally adopts a box girder structure, which is expensive. Although it can be reused, it is difficult to inst...

Problems solved by technology

The pre-buried underframe has low cost and low cost, but it cannot be reused, and it is difficult to disassemble. It is generally suitable for occasions with long construction period and infrequent transfer of tower cranes

The ground-anchored or ballast-type underframe generally adopts a box girder structure, which is expensive. Although it can be reused, it is difficult to install, inconvenient to transfer and transport because of the complex force on the underframe, large structural size, and heavy weight. Shortcomings
