Description

Technical Field

[0001] The invention relates to the field of bridge construction, in particular to a power device for a C-shaped hook for a hanging basket to travel. Background Art

[0002] In the construction of the front support basket of the bridge, the walking device is generally composed of a jack, power transmission, and load-bearing structure; the company's previous basket sliding traction power system adopts a combination of a 250t jack, 32mm finely rolled threaded steel, and a special slider. The slider is arranged in the design position before the basket is assembled, and the overall design is an inverted "concave" shape, which serves as a left and right limit measure during sliding. When the basket slides, it strictly follows the principles of symmetry, synchronization, and uniform force; mark the scale on the finely rolled threaded steel in advance, and pay close attention to the slider limit during the sliding process. Every 10m of sliding, the measurement team measures the position of the basket and corrects it in time. When the basket is close to the end position, the scale marking and measurement correction should be encrypted to ensure that the basket stops at the designed position; then the traction force generated by the jack acts on the C-type hook, causing the C-type hook to move to the end of the beam, The C-hook and the inclined cable provide the fulcrum of the hanging basket; when the hanging basket is in the demoulding and walking state, the C-hook and the rear vertex are used to resist the cantilever overturning tendency of the hanging basket; the existing walking device has the following defects that increase the difficulty of construction: the thrust blocks are manually placed in the groove, which increases manpower and is easy to lose on site; due to the friction between the slide and the track, the movement speed of the slide and the return oil speed of the hydraulic cylinder are not coordinated, which wastes time and brings certain adverse effects during use. For this reason, we propose a power device for the C-hook for hanging basket walking. Summary of the invention
