Background technique

With China's highway, the rapid development of high-speed rail, subway, freeway tunnel, high-speed rail tunnel and subway tunnel Disease automatic detection be increasingly urgent to, the present invention is the important component of various Tunnel automation detection devices.

Since the shape in various tunnels is all circular design, so the appearance profile of various automatic checkout equipments is with circle For first choice.But since the radius in tunnel varies, in order to enable same equipment to be compatible with a variety of tunnels, test equipment it is main Structure is designed to that the composite structure with lifting and contractile function is necessary.

Utility model content

The purpose of this utility model is to provide a kind of Tunnel testing combined systems, to solve the above technical problems.

The utility model uses following technical scheme to achieve the above object:

A kind of Tunnel testing combined system, including bracket, bearing platform, telescopic arm, sensor, slide bar and oil cylinder, institute It states combined system bottom surface and the oil cylinder gone up and down for bearing platform is housed, the oil cylinder is fixed with bearing platform, the bearing platform It is fixed with support vertical, the bracket is semi-circular design for installing telescopic arm, the bracket, and the telescopic arm is fixed on branch On frame, the telescopic arm is made of motor, lead screw and sliding block, and the telescopic arm is fixed on bracket by bottom plate, the slide bar, Lead screw and bottom plate are integrated molded design, and the sliding block provides power by motor and moves up and down along lead screw, the slider table Face is equipped with sensor.

Preferably, the bracket, bearing platform, lead screw, slide bar, sliding block material are stainless steel.

Compared with prior art, the utility model has the advantage that the utility model structure is simple, and design rationally, is made Valence is at low cost；After test equipment enters tunnel, the circle like tunnel contour test panel for completing to be made of multiple telescopic arms is first had to The fitting of the heart and the tunnel center of circle (two centers of circle are overlapped as far as possible)；Then, then sensor is adjusted at a distance from tunnel wall, pass it The best measuring distance of sensor test.Test equipment first pass through the range sensor on telescopic arm measure away from tunnel surface away from From, the height that lifting partly needs to go up and down is calculated, hydraulic part is then started, cylinder movement is made to drive bearing platform lifting, Reach the adjustable height of setting.Then, then by the range sensor on telescopic arm measure after jacking system adjusts away from tunnel table The distance in face determines the stroke of telescopic arm compared with the best measuring distance of sensor, and test equipment controls stepping electricity respectively Machine drives lead screw rotation, moves telescopic arm, reaches the best measuring distance of sensor.After the completion of test, telescopic arm and lifting Platform restores initial point, keeps equipment volume minimum, center of gravity is minimum, convenient transportation, securely and reliably, preferably promotes the use of.

Detailed description of the invention

Fig. 1 is the structure chart of the utility model Tunnel testing combined system.

In figure: 1, bracket, 2, telescopic arm, 3, sliding block, 4, slide bar, 5, lead screw, 6, sensor, 7, distance measuring sensor, 8, step Into motor, 9, oil cylinder, 10, bearing platform, 11, oil pump.

Specific embodiment

The utility model is further elaborated in the following with reference to the drawings and specific embodiments.

As shown, a kind of Tunnel testing combined system, including bearing platform 10, oil cylinder 9, oil pump 11, bracket 1, stretch Contracting arm 2, stepper motor 8, slide bar 4, lead screw 5, sliding block 3 and sensor 6, the combined system bottom surface, which is equipped with, is used for bearing platform The oil cylinder 9 of 10 liftings, the oil cylinder 9 are connected with oil pump 11 by oil pipe, and fixed with bearing platform 10, the bearing platform 10 It is vertically fixed on together with bracket 1, the bracket is semi-circular design for installing telescopic arm 2, the bracket 1, described flexible Arm 2 is fixed on bracket 1, and the telescopic arm 2 is made of 8 lead screw 5 of stepper motor and sliding block 3, the telescopic arm and slide bar 4, silk Thick stick 5 and sliding block 3 are integrated molded design, and the slide bar 4 keeps the movement of sliding block 3 more steady, and the telescopic arm 2 passes through stepping electricity Machine 8 supplies power to lead screw 5, moves up and down sliding block 3, and 3 surface of sliding block is equipped with sensor 6 and distance measuring sensor 7.

Utility model works principle: telescopic arm 2 is fixed in semi-circular bracket 1.Semi-circular bracket 1, which is vertically fixed on, holds On galassing platform 10, after test equipment enters tunnel, first have to complete to be made of multiple telescopic arms 2 like tunnel contour test panel The fitting in the center of circle and the tunnel center of circle；Then, then sensor 6 is adjusted at a distance from tunnel wall, test its sensor 6 best Measuring distance.Test equipment first passes through the range sensor 7 on telescopic arm 2 and measures the distance away from tunnel surface, calculates lifting The height for partly needing to go up and down, then starts hydraulic part, makes the movement of oil cylinder 9 that bearing platform 10 be driven to go up and down, reaches setting Adjustable height.Then, the distance away from tunnel surface after jacking system adjusts is measured by the range sensor 7 on telescopic arm 2, then Compared with best measuring distance needed for sensor 6, the stroke of telescopic arm 2 is determined, test equipment controls stepper motor 8 respectively It drives lead screw 5 to rotate, moves telescopic arm 2, reach the best measuring distance of sensor 6.After the completion of test, telescopic arm 2 and hold Galassing platform 10 is restored to initial point, keeps equipment volume minimum, center of gravity is minimum, convenient transportation.The utility model will have lifting and The component of contractile function is combined, and lifting part completes the quasi- of the centre point in the test equipment center of circle and the detected tunnel center of circle It closes, constriction completes the detection sensor installed on telescopic arm and tunnel wall keeps optimal detection distance, perfectly completes Two main points in tunnel test, technically realization can there are many selection and approach.

The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired Change, replacement and variant is still fallen within the protection scope of the utility model.
