Mobile bridge pier stud quality detection device

Abstract

The invention discloses a mobile bridge pier stud quality detection device belonging to the technical field of bridge detection equipment. The mobile bridge pier stud quality detection device comprises detection equipment and a detection frame part, wherein the detection frame part is a metal bracket (1) assembled by a plurality of metal pipes, a spring (2), a detection equipment installing platform (4) and a remote control device (5), wherein one end of the spring is connected with the metal bracket (1), the other end of the spring is connected with a pulley block (3), the detection equipment installing platform (4) is connected with two side surfaces of the metal bracket (1) by threads, and the remote control device (5) is arranged on an closed surface, opposite to an opening surface, of the metal bracket (1) by a thread and used for providing mobile power, three surfaces of the metal bracket (1) are closed and one surface of the metal bracket (1) is opened, the opening surface is positioned on a jointing surface of a pier stud and a cross beam, and during moving, the cross beam can pass through the opening surface and the opening size of the opening surface is greater than the width size of the cross beam of the pier stud. The mobile bridge pier stud quality detection device has the advantages of remarkable energy saving and emission reducing effects, simple structure, safety and reliability; the field of detecting the bridge pier stud is enlarged, and multiple items of analysis indexes are provided for completely and objectively evaluating the improvement of the comprehensive quality of the bridge pier stud.

Description

Technical field: [0001] The invention relates to a mobile bridge pier column quality detection device, which belongs to the technical field of bridge detection equipment. Background technique: [0002] The application field of this technology is mainly aimed at the following three types of bridges: 1. Bridges under construction or bridges to be opened to traffic; For special bridges that have been monitored for a long time, especially some bridges with reduced pile foundation bearing capacity or serious erosion in the river, according to the relevant regulations of the Ministry of Transport, the quality of the pier concrete must be tested; to ensure that the bridge can be used safely during the opening to traffic. operate. At present, two methods are usually used in the quality inspection of bridge pier columns. One is that the inspectors use the inspection frame of the bridge quality inspection vehicle to inspect the top of the pier column 8 meters below the top, and the o...

Problems solved by technology

However, there are still three problems in the above method in the actual detection work: 1. The length of the detection pier column is limited, and only the bridge pier column with a height of 11 meters can be detected, but many pier columns in the actual construction site are more than 11 meters; 2. , There is a large potential safety hazard. When using bridge quality inspection vehicles for inspection, due to the large size of the inspection vehicle, it needs to occupy at least one lane, hindering the normal passage of vehicles, and there is a large potential safety hazard in the traffic section; 3. More personnel and testing equipment are used. , one bridge testing vehicle is required for testing, and 5 testing and operating personnel are required. The testing and operating personnel are divided into an upper group and a lower group. Inspection), the lower inspection team on the ground needs at least 2 people, so at least 5 people are needed to complete the entire inspection; 4. The inspection data is limited, only the upper and lower parts of the pier can be collected, and the intermediate data cannot be collected

[0003] In order to overcome the shortcomings of existing bridge pier column concrete quality detection devices, such as limited detection height, relatively large potential safety hazards, and the use of many personnel and equipment, the present invention is provided.
