Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, a kind of bridge reinforcement distributed detection system based on mobile platform, comprises mobile platform (not shown), pressure generator 1, gasholder 4, valve 7, cylinder, bridge reinforcement distribution detecting instrument 13 and sliding screw 8;
Air guide path 3 is passed through toward 4 li of inflations of gasholder in the gas outlet 2 of described pressure generator, the gas storage mouth of gasholder is connected with strainer 5 by air guide path successively, the noise that described strainer 5 can reduce gas to be produced while exerting pressure, then strainer 5 is communicated with one way valve 6 by air guide path, one way valve 6 can ensure gas unidirectional conducting, then one way valve 6 is communicated with valve 7 by air guide path, and valve 7 is controlled unlatching and the shutoff of gas circuit.
Separate four road air guide paths from valve 7, be respectively from top to bottom first, second, third, fourth air guide path, described cylinder comprises vertical cylinder 11 and rotary cylinder 12, vertically cylinder 11 and rotary cylinder 12 are double-acting cylinder, first therefore, the 4th air guide path is communicated with vertical cylinder 11 respectively, second, third air guide path is communicated with rotary cylinder 12 respectively.
Described sliding screw 8 is fixed on the bottom of mobile platform, sliding screw 8 drives whole detection system to detect surface level motion at bridge, the bottom of described sliding screw 8 is provided with slide block 9, described slide block 9 is fixed by the base of connecting rod and rotary cylinder 12, the piston rod of described rotary cylinder 12 is fixed on the piston rod of vertical cylinder, and described vertical cylinder 11 is fixed on bridge reinforcement distribution detecting instrument 13;
In mobile platform motion process, described rotary cylinder 12 can be regained bridge reinforcement distribution detecting instrument 13 by rotation, the described vertical cylinder 11 bridge reinforcement distribution detecting instrument 13 that can raise, in the time that mobile platform detects, described rotary cylinder 12 can discharge described bridge reinforcement distribution detecting instrument by rotation, and described vertical cylinder 11 can reduce described bridge reinforcement distribution detecting instrument.
