Problems solved by technology

Due to the curved shape of the shaft wall components, when the traditional hook wire rope hanger is used, the resultant force action point does not pass through the center of gravity of the shaft wall components, so the verticality of the shaft wall components cannot be guaranteed during hoisting.
On the other hand, due to the installation requirements of the shaft wall, there is no and cannot be provided with corresponding hanging points on the outside of the shaft wall components, so it is difficult to meet the needs of shaft construction such as tight construction schedule, high quality, convenient lifting and transportation, and fast and reliable installation.

Embodiment Construction

[0011] See attached figure 1 , 2 , a special spreader for shaft construction, which includes: a counterweight 1, a hanging plate 2, and a bottom plate 3;

[0012] The counterweight 1 is connected to the hanging plate 2 through the connecting rod in the inner direction of the shaft wall member 5;

[0013] Hanging plate 2 is used to connect the crane hook;

[0014] The bottom plate 3 is fixedly connected to the hanging plate 2 through the stiffener plate, and connected to the well wall component 5 through the bolts on the upper surface of the well wall component 5 .

[0015] Further, the special spreader for shaft construction also includes: a clamping arm 4; the upper part of the clamping arm 4 is bent and connected to the bottom plate 3 through a reinforcing plate, and the lower part is bent to clamp the outside of the shaft wall member 5.

[0016] Further, the connecting rod connecting the counterweight 1 and the suspension plate 2 is adjustable in length.

Abstract

The invention belongs to the technical field of lifting machines, and relates to a lifting tool, in particular to a lifting tool special for shaft construction. According to the technical scheme, a balancing weight is connected with a lifting plate through a connecting rod in the inner side direction of a shaft wall component; the lifting plate is used for being connected with a crane hook; and a base plate is fixedly connected with the lifting plate through reinforcing ribs and detachably connected with the upper surface of the shaft wall component. The lifting tool special for shaft construction can well adapt to the irregular shape and the gravity eccentricity of the shaft wall component to ensure the uprightness of the shaft wall component in lifting, and the lifting tool can adapt to different types of shaft wall components by adjusting the weight of the balancing weight or the length of the connecting rod according to different structures and weights of the site shaft wall components; and the lifting tool and the shaft wall component are connected through bolts, so that installation and disassembly are quick and reliable.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, in particular to a hoisting tool. Background technique [0002] The rapidity and safety of modern shaft construction are important indicators for evaluating construction efficiency. In the caisson method construction scheme, the effect and speed of modular shaft wall installation directly affect the entire shaft construction process. Because the well wall component is arc-shaped, when the traditional hook wire rope hanger is used, the resultant force point of its action does not pass through the center of gravity of the well wall component, so the vertical of the well wall component cannot be guaranteed during hoisting. On the other hand, due to the installation requirements of the shaft wall, there is no and cannot be provided with corresponding hanging points on the outside of the shaft wall components, so it is difficult to meet the needs of shaft construction such as tight construc...
