Embodiment 1

[0029] refer to Figure 1-Figure 6 , the present invention is a kind of mobile bridge deflection detector for bridge engineering detection, it is characterized in that: comprise moving body 1, laser testing device 2, rotating device 3 and fixing device 4;

[0030] The moving body 1 includes a moving bracket 101, a moving wheel 102, a flying rotor 103, a moving rotor 104 and a controller 105. The moving bracket 101 is in an "L" shape, an "X"-shaped bracket 1011 is formed on the upper end of the moving bracket 101, and the left end of the moving bracket 101 is formed. Mounting brackets 1012 are formed, six moving wheels 102 are installed on the upper and left ends of the moving bracket 101, four flying rotors 103 are installed on the upper end of the "X"-shaped bracket 1011 at even intervals, and two moving rotors 104 are installed. And are respectively installed on the mounting brackets 1012, the mobile body 1 includes a flight mode, a climbing mode, an attachment mode and a de...

Embodiment 2

[0047] Please refer to Figure 7 , in the second embodiment, other structures remain unchanged, and another structural form of the rotating base 301 is provided, which aims to solve the problem that the mobile body 1 is difficult to maintain balance when the rotating base 301 is attached to the wall , the two ends of the rotating base 301 are installed with supporting inclined rods 308, and one end of the supporting inclined rods 308 close to the main body 401 of the electric suction cup is installed with a supporting ring 309. In the initial state, the supporting ring 309 is not in contact with the wall. When the suction cup body 401 is extended, the support inclined rod 308 and the support ring 309 will move in the same direction as the rotating base 301. When the electric suction cup body 401 is adsorbed on the wall, the support ring 309 contacts the wall to form a fulcrum to maintain the stability of the device sex.

Abstract

The invention is applicable to the technical field of bridge deflection detection, and provides a mobile bridge deflection detector for bridge engineering detection. An "X"-shaped bracket is formed at the upper end of the movable bracket, a mounting bracket is formed at the left end of the movable bracket, and the movable wheel is installed on the movable bracket. On the bracket, the point laser transmitter is installed on the upper end of the rotating device, the moving projection target is set at the fixed position of the structure set as the reference point, the output shaft of the rotary motor is connected with the pinion transmission, the point laser transmitter is installed on the pan, the micro-electric The cylinder is installed on the upper end of the mounting bracket, the vacuum pump is installed on the side of the rotating base away from the gimbal, the support column is connected to the lower left end of the moving bracket, and the lower end of the rotating base is installed on the upper end of the support column. The laser transmitter is moved and fixed to the wall where the target area is located, so that the point laser transmitter moves with the bridge structure at the point to be measured to measure the deflection change value, so the installation and measurement of the point laser transmitter is more convenient.

Description

technical field [0001] The invention belongs to the technical field of bridge deflection detection, in particular to a mobile bridge deflection detector for bridge engineering detection. Background technique [0002] Bridge deflection refers to the linear displacement of the cross-section center of the bridge along the vertical direction of the axis when the bridge is bent and deformed. It is an important indicator to be tested in the detection of bridge health conditions. At present, the bridge deflection is generally measured by a level and detected by a laser projection deflection tester. The level is used to measure and test accurately, but the installation equipment is more complicated; the detection by a laser projection deflection tester is less affected by light and has less accuracy. high. [0003] In the actual measurement process, in order to ensure that the data measured by the sensor can effectively reflect the change of the bridge deflection, the operator must...
