Embodiment 1

[0032] This embodiment discloses a bridge steel column hoisting swivel device and swivel method, as shown in the attached Figure 3-5 , including a pair of coaxial holes 1 opposite to each other. Hole 1 is set on the side wall where the lifting point is set at one end of the steel column; it includes a stressed steel plate connected to the side wall of the steel column. In contrast to hole 2, the contour of hole 1 is located on the periphery of the contour of hole 2; it also includes a pin shaft, which penetrates through the steel column through hole 1 and hole 2, and the two ends of the pin shaft are located outside the steel column, which can use existing devices such as slings Connect with the cableway to realize the rotation.

[0033] The end where the pin is located is taken as the main lifting point, and two lifting lugs are welded on the other end of the steel column, on the upper surface of the horizontal lifting, to assist the rotation and serve as the auxiliary lifti...

Embodiment 2

[0035] On the basis of embodiment 1, refer to as attached Figure 5 , the stressed steel plate is welded on the inner side of the column, and welded with the vertical stiffening plate and the circumferential stiffening plate attached to the first hole. The diameter of hole two on the stressed steel plate is smaller than the diameter of hole one on the side wall of the steel column, and the pin shaft passes through hole two together with hole one, so as to prevent the column from directly participating in the stress. Between the stressed steel plate and the vertical stiffening plate, between the inner wall of the steel column and the vertical stiffening plate 4, reinforcing ribs are welded, in a triangular shape, arranged in opposite pairs on both sides of the vertical stiffening plate. The force here is mainly composed of the steel plate, the vertical stiffener of the steel column and the circumferential stiffener. The ribs strengthen the stability of the internal structure of...

Embodiment 3

[0037] On the basis of Embodiment 1, the cross-sectional shape of the steel column can be rectangular or circular, and the line between the two opposite holes on the side wall of the steel column and the centroid is the middle division of the cross section of the steel column Wire. The two ends of the pin shaft and the side panels of the steel column are positioned by a limit device. The pin shaft can be 110 type, and there is a through hole for limit on the outside; the limit device can use limit sleeves, nuts, gaskets and limit pin. At the appropriate position of the outermost limit, a limit pin longer than the length of hole one on the side wall is fixed through the through hole on the outside of the bearing pin.

Abstract

The invention relates to the field of bridge engineering, in particular to a bridge steel upright hoisting and turning device and a turning method. The turning device mainly comprises a pin shaft penetrating through a steel upright post, a stressed steel plate and a lifting appliance device used for connecting the steel upright post and a cableway. The pin shaft penetrates through a hole formed inthe steel upright post and is connected with the external lifting appliance device, and the lifting appliance and the pin shaft or the pin shaft and the upright post can rotate mutually. The stressedsteel plate is arranged on the end face of the hole of the side wall of the upright post, the stressed steel plate is welded with the vertical stiffening plate and the circumferential stiffening plate of an opening accessory, and the stressed steel plate is provided with corresponding holes, so that the pin shaft penetrates through the stressed steel plate and the side wall of the upright post, and the side wall of the upright post is prevented from directly participating in stress. The bridge steel upright hoisting and turning device is large in hoisting weight, ensures that the steel upright post is stressed stably and uniformly in the hoisting and turning process, ensures that the axis of the turned steel upright post is consistent with the vertical direction, is beneficial to field installation, saves construction time, and can repeatedly use the pin shaft, related lifting appliances and other components in the turning device, thereby saving construction cost.

Description

technical field [0001] The invention relates to a swivel device, in particular to a swivel device and a swivel method for hoisting a bridge steel column. Background technique [0002] The steel columns used in the bridge structure are generally processed and manufactured in the processing factory, and then transported to the bridge construction site after completion, and installed and constructed with large-scale lifting equipment. Lifting equipment generally uses cranes, cable cranes, gantry cranes, etc. For the construction of steel columns with long sections and large cross-sections, the conventional installation method is to divide a single long steel column into several short sections for processing and manufacturing, and then hoist and install the short sections in place. If the on-site construction site, lifting equipment, component stiffness and other conditions permit, the short-segment steel columns can also be assembled into a long-segment structure, and then the...
