Tunnel monitoring equipment mounting trolley and using method thereof

Abstract

The invention discloses a tunnel monitoring equipment mounting trolley and a using method thereof. The trolley comprises a walking mechanism, the walking mechanism comprises two walking bases arranged in a spaced mode and idler wheels arranged under the walking bases, the upper side of the walking mechanism is connected with a vertical telescopic mechanism, the vertical telescopic mechanism comprises four vertically-arranged hydraulic oil cylinders, and the upper side of the vertical telescopic mechanism is connected with a telescopic working platform. The telescopic working platform comprises a first platform plate and a second platform plate, and a third platform plate is slidably connected between the first platform plate and the second platform plate. The height and the width of the trolley can be conveniently adjusted, and the trolley can well adapt to the size of a rectangular tunnel; according to the tunnel monitoring equipment, passing of vehicles in the lower portion is not affected during operation, so that installation of the tunnel monitoring equipment gets rid of time limitation, installation can be carried out without waiting for specified maintenance time every week, high-strength installation does not need to be carried out at night, and the construction efficiency and safety of construction personnel are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of a trolley for installing tunnel monitoring equipment, in particular to a trolley for installing tunnel monitoring equipment and a method for using the trolley. Background technique [0002] With the continuous development of the transportation industry, the construction level of urban roads is also constantly improving, but the use of space is becoming increasingly narrow, and the development and use of urban underground space is becoming more and more important. As a kind of underground transportation infrastructure, the municipal road tunnel plays a self-evident role. Ensuring the structural safety of tunnels in operation is the key to municipal tunnel maintenance, and structural health monitoring is a key part of this work. The installation of various monitoring sensors on the tunnel structure in operation has the following challenges: (1) Traffic interruption: the area outside the outermost lane of t...

AI Technical Summary

Problems solved by technology

The installation of various monitoring sensors on the tunnel structure in operation has the following challenges: (1) Traffic interruption: the area outside the outermost lane of the tunnel where installation personnel and auxiliary vehicles (such as climbing vehicles) can stay is very limited (generally less than 0.5m), the installation of the monitoring sensor must interrupt the traffic flow of one lane; when installing the monitoring sensor at the mid-span position of the roof, there must be a climbing vehicle to cooperate, which will surely occupy multiple lanes, so that the traffic of the entire tunnel must be temporarily interrupted

(2) Short installation time: Since the traffic flow must be interrupted during the installation process, it needs to be approved by administrative departments at all levels and it is difficult to obtain approval. Therefore, it is generally only possible to use the established tunnel closed management period for installation, and the weekly closed management time of municipal road tunnels is generally 3 hours, leaving very limited time for monitoring sensor installation

(3) Low installation efficiency and safety: The closed maintenance period of the tunnel is generally from 2:00 to 5:00 in the morning, and it is difficult to guarantee the construction efficiency and safety of construction personnel when working under such high-intensity conditions

(4) The installation of auxiliary equipment is simple and the efficiency is extremely low: At present, the installation auxiliary tools for high-level sensors are mainly ladders and climbing vehicles. During frequent movement, the height and position must be adjusted repeatedly, and the accuracy and efficiency are very low.

[0003] At present, there is no related product or public patent that can solve the practical problems of continuous flow, efficient and safe installation of tunnel monitoring sensors in the above-mentioned operations
