AI Technical Summary

Technical Problem

In the existing steel truss jacking construction, the sliding shoe lacks a limiting structure when moving laterally, which means that the jacking equipment must always be held against the surface of the limiting plate, affecting the normal sliding of the sliding shoe.

Method used

A pressure-sensitive intelligent sliding shoe device was designed. By setting a limiting plate and a plug-in structure inside the sliding shoe, the sliding shoe is stably limited by the cooperation between the plug-in plate and the limiting plate, ensuring that the sliding shoe does not come into contact with the slide beam during movement.

Benefits of technology

This design achieves stable positioning of the sliding shoe during movement, avoids continuous pressure from the jacking equipment on the limiting plate, and improves the sliding efficiency and construction safety of the sliding shoe.

Abstract

This invention relates to the field of steel truss construction technology, specifically to a pressure-sensitive intelligent sliding shoe device for steel truss jacking construction. The device includes: a sliding beam, a sliding shoe placed on the surface of the sliding beam, a pressure sensor on the surface of the sliding shoe, a jacking head on the surface of the sliding shoe, a horizontal plate inside the sliding shoe, a connecting plate fixed to the bottom of the horizontal plate, an L-shaped rod fixed to the surface of the horizontal plate, and a limiting plate at the bottom of the L-shaped rod. The beneficial effects are: when the surface of the limiting plate contacts both sides of the sliding beam, the L-shaped rod can continue to insert into the interior of the limiting plate, and the bottom of the connecting plate inserts into the connecting groove, so that one side of the connecting groove is supported. One side of the horizontal sliding plate supports the surface of the limiting plate, and the fourth tooth on the surface of the horizontal sliding plate engages with the surface of the third tooth, stabilizing the position of the limiting plate. The limiting plate supports both sides of the sliding beam, playing a limiting role. When the sliding shoe moves, the limiting plate can play a limiting role.
