Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
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 gasholder 4 li inflation 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, described strainer 5 can reduce the noise produced when gas is exerted 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 controls unlatching and the shutoff of gas circuit.
Four road air guide paths are separated from valve 7, be respectively first, second, third, fourth air guide path from top to bottom, described cylinder comprises vertical cylinder 11 and rotary cylinder 12, vertical cylinder 11 and rotary cylinder 12 are double-acting cylinder, therefore the first, the 4th air guide path is communicated with vertical cylinder 11 respectively, and 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 move at bridge machinery surface level, 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 regain bridge reinforcement distribution detecting instrument 13 by rotating, described vertical cylinder 11 can lift bridges reinforcing bar distribution detecting instrument 13, when mobile platform detects, described rotary cylinder 12 can by rotating release described bridge reinforcement distribution detecting instrument, and described vertical cylinder 11 can reduce described bridge reinforcement distribution detecting instrument.
Described sliding screw 8 is controlled by stepper motor, and described vertical cylinder 11 and rotary cylinder are pneumatic control, controls the motion of described vertical cylinder and rotary cylinder by controlling gas flowing.
By conducting and the closed condition of four road air guide paths of by-pass valve control, described vertical cylinder can be controlled move up and down and described rotary cylinder rotary motion, the movement velocity of described vertical cylinder and described rotary cylinder is regulated, by the size regulating the angular adjustment knob of described rotary cylinder to regulate the anglec of rotation by the size of the air inlet port of adjusting cylinders.When vertical cylinder is in downward state, rotary cylinder be in the right 90-degree rotation state time, detecting instrument and earth surface, thus by stepper motor motion drive detecting instrument complete from left to right or dextrosinistral motion, complete the detection of a segment distance.
The course of work:
First pressure generator is constantly inflated to gasholder, after the gas in gasholder reaches certain pressure intensity, pressure generator quits work, and gasholder is by connecting valve after strainer, one way valve, when valve all turns off, rotary cylinder and vertically cylinder do not have active force.
When needs bridge reinforcement distributed detecting instrument move upward time, open the valve of the enterprising gas port 10 controlling vertical cylinder, thus produce the air-flow of a High Voltage, the piston promoting vertical cylinder 11 moves downward, piston due to vertical cylinder is fixed on rotary cylinder 12, then vertically the cylinder body of cylinder moves upward, and bridge reinforcement distribution detecting instrument 13 is fixed on the cylinder base of vertical cylinder 11, therefore also moves upward.Bridge reinforcement distribution the moving downward of detecting instrument, rotary motion and move upward similar.
In the original state of carrying out detecting, first bridge reinforcement distribution detecting instrument 13 is accepted, be moving upward and state left after 90-degree rotation in Fig. 1 state, after starting detection, first a road air guide path of rotary cylinder 12 is opened, make rotary cylinder 90-degree rotation to the right, namely bridge reinforcement is made to distribute detecting instrument straight down, then the road air guide path moved downward of vertical cylinder is opened, bridge reinforcement distribution detecting instrument is moved downward, with detection surface contact, then allow stepping motor movement that sliding screw 8 is moved from left to right or from right to left under the drive of motor, namely the detection of a segment distance is completed.When after detection of end, the detecting instrument that first distributed by bridge reinforcement moves upward, then 90-degree rotation left, and the detecting instrument that namely bridge reinforcement can be distributed is accepted, and facilitates mobile platform to move.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not limited by the examples; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
