Jacking device for bridge construction

Abstract

The invention discloses a jacking device for bridge construction. The jacking device comprises a jacking device body, a pressing sleeve is fixedly connected to the top of the jacking device body, square sleeves are fixedly connected to four sides of the pressing sleeve, sliding sleeves are slidably connected to the inner parts of the square sleeves, and protecting sleeves which are located outsidethe square sleeves are arranged on the surfaces of the sliding sleeves in a sleeving mode. According to the jacking device for bridge construction, discs drive a screw to be connected into a threadedhole in a threaded mode to limit the sliding sleeves, and then the sliding sleeves protect a thin steel plate from the four sides of the pressing sleeve through limiting mechanisms and the protectingsleeves, so that the jacking device has the advantage that the thin steel plate of the top of the jacking device is prevented from falling down during installation, the problem that the thin steel plate is prone to sliding and falling when the thin steel plate is paved at the top of the jacking device due to the facts that the paved steel plates are comparatively many and the top of an existing jacking device is not provided with a certain protecting mechanism is solved, and a situation that the body of a user is prone to being hurt in the falling process of the steel plates is avoided at thesame time.

Description

technical field [0001] The invention relates to the technical field of jacking devices, in particular to a jacking device for bridge construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. Buildings and bridges generally consist of superstructures, substructures, supports and subsidiary structures. [0003] In bridge construction, jacking devices are usually used for support. Since the pier surface of bridges is usually not horizontal, thin steel plates are often used to support the top and bottom of the jacking device. However, the top of the existing jacking device does not have A certain protection mechanism, so that when the thin steel plate is placed on ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a jacking device based on bridge construction, which has the advantage of being able to prevent the thin steel plate on the top of the jacking device from falling during installation, and solves the problem of the top of the existing jacking device. It does not have a certain protection mechanism, so when placing the thin steel plate on the top of the jacking device, due to the laying of many thin steel plates, the thin steel plate is prone to slide and fall
