Description

Novel cleaning device for bridge expansion joint

Technical Field

This patent belongs to road and bridge equipment field, specifically is a novel cleaning device for bridge expansion joint.

Background

In modern highway construction, bridges are indispensable buildings in highways and railways, and are usually built on rivers, lakes and mountain stream, so that vehicles and pedestrians can pass smoothly. The bridge is generally composed of an upper structure, a lower structure and an accessory structure, wherein the upper structure mainly refers to a bridge span structure and a support system; the lower structure comprises a bridge abutment, a bridge pier and a foundation;

the bridge expansion joint is a telescopic device arranged at the movable end of the bridge superstructure and the bridge deck fracture joint. In order to prevent the building components from generating cracks or damages due to the climate temperature change (thermal expansion and contraction), a construction joint is arranged along the proper position of the building or the direction of the construction joint of the building.

During the running process of a normal vehicle and under natural conditions, a lot of dust, stones, cinder and other impurities are deposited between bridge expansion joints, and the dust, the stones, the cinder and other impurities need to be cleaned at regular time; the existing cleaning equipment generally uses tools such as crowbars and the like to loosen stones, coal slag and other impurities inlaid in bridge joints through manual cleaning, and adopts a high-pressure water gun or an air gun to directly clean the stones, coal slag and other impurities, wherein dust and impurities in expansion joints can be effectively cleaned during manual cleaning, but the manual cleaning is long in time consumption, low in efficiency and high in labor cost; meanwhile, the high-pressure water cleaning and air gun is easy to generate dust and the cleaned impurity scattering area is large and inconvenient to collect.

The existing cleaning device for the bridge expansion joint has the problems of low cleaning efficiency, poor practicability and the like. For example, chinese patent publication No. CN 216074932U, publication No. 2022.03.18 discloses a bridge expansion joint cleaning device, which uses two rows of blades to loosen the pile of expansion joints and uses a dust collector to clean the pile. However, the depth adjustment of the shovel blade is inconvenient, the requirement on the dust collection device is high, and the cleaning efficiency is difficult to ensure.

If the publication number is CN 110804983A, the Chinese patent publication date is 2020.02.18 discloses a bridge seam expansion device, a high-pressure water gun with adjustable nozzle direction is adopted to clean the expansion seam, and a dust collection device is used to collect magazines; but cleaning is difficult for compact impurities in the expansion joint.

For example, the Chinese patent with the authority bulletin number of CN 108978544A and the authority bulletin day of 2018.12.11 discloses a bridge seam cleaning device, which is cleaned by extending a roller broom into an expansion seam, arranging dust collection devices before and after cleaning, installing the device on a large-sized vehicle, and installing a ferromagnetic device before and after the vehicle. The water gun is not required to clean, but the vehicle is inconvenient to use when the length of the bridge seam is short due to the fact that the vehicle is large, and the alignment adjustment of the working position of the bridge seam is difficult.
