Background

With the improvement of detection technology, more and more road detection vehicles have appeared, which integrate photoelectric technology, IT technology and 3S technology into a whole by taking a motor vehicle as a platform. Under the normal running state of the vehicle, the system can automatically complete the data acquisition, analysis, classification and storage of road surface images, road surface shapes, road facility three-dimensional images, flatness, road geometric parameters and the like. The method provides an effective data acquisition means for detecting the damage, the flatness, the rut and the potential safety hazard of the road surfaces of expressways, high-grade highways, urban municipal roads, airport runways and the like and digitally managing road auxiliary facilities.

The existing detection vehicle has incomplete functions and is difficult to complete the detection of various parameters at one time.

Disclosure of Invention

The invention aims to provide a multifunctional detection vehicle which has the advantage of being capable of detecting both the pavement evenness and the pavement bearing capacity.

The technical purpose of the invention is realized by the following technical scheme:

a multifunctional detection vehicle comprises a vehicle body and a three-dimensional scanner installed at the rear end of the vehicle body, wherein a mounting hole penetrating through a chassis of the vehicle body is formed in the vehicle body, and a drop hammer deflectometer is installed on the mounting hole; the drop hammer type deflectometer comprises a doorframe-shaped support and a drop hammer device, wherein two lifting hydraulic cylinders are arranged on the doorframe-shaped support, a bearing plate and two connecting arms fixed on the bearing plate are arranged on the drop hammer device, and piston rods of the two lifting hydraulic cylinders are respectively connected with the two connecting arms.

So set up, together integrated to detecting the car with weight-dropping deflectometer and three-dimensional scanner, so, can realize detecting the road surface roughness, also can detect the road surface bearing capacity through weight-dropping deflectometer, when using weight-dropping deflectometer, make the weight-dropping device descend until with ground contact through hydraulic cylinder, then start the weight-dropping device and make the weight-dropping on it rise to set for the height after, the free drop hammering can accomplish the detection on the bearing board.

More preferably: the doorframe-shaped support is fixed on a frame, and the frames positioned at the two sides of the drop hammer device are provided with safety locks for supporting the bearing plate.

So set up, through the setting of safety lock, when taking place the condition such as hydraulic system out of control, can play the support loading board, prevent that it from taking place the whereabouts not using.

More preferably: the safety lock comprises two bases fixed on the frame, a rotating shaft rotatably connected to the two bases, a rotating arm fixed on the rotating shaft along the radial direction of the rotating shaft, a driving hydraulic cylinder connected with the rotating arm, and two supporting grippers fixed on the rotating shaft.

So set up, drive the axis of rotation through the drive pneumatic cylinder and rotate to the upset of support tongs is driven, after supporting the upset of tongs to the hammer device direction that falls, supports the tongs and can be on the lift route of loading board, consequently, when the loading board is located and supports the tongs top, can hold the loading board.

More preferably: one side of the supporting hand grip is convexly provided with a supporting pin, and one side of the supporting hand grip, which is provided with a supporting pin, is abutted against the side face of the base.

So set up, when using to support the tongs and support, the supporting pin can support at the base to play the restriction and support the tongs and continue to take place the upset, and then can improve the support effect that supports the tongs, simultaneously, can reduce the load to the drive pneumatic cylinder in the support process.

More preferably: the safety lock is including fixing the base on the frame, fixing the connecting axle on the base, rotating the support tongs of connecting on the connecting axle, being used for keeping supporting the torsional spring of tongs at the support station and installing the support pneumatic cylinder on supporting the tongs, support the tongs and support one side of locating the base, support the pneumatic cylinder and be located one side that the support tongs deviates from the base, just be provided with a through-hole that runs through the support tongs on supporting the tongs, the piston rod that supports the pneumatic cylinder is inserted and is located in the through-hole and can stretch out the through-hole appearance and form the supporting pin.

So set up, when needs support the loading board, start to support the pneumatic cylinder and make its telescopic link stretch out from the through-hole and form the supporting pin, so, when the loading board wants to support the tongs application of force, can support the loading board under the supporting pin effect and live. And when the supporting effect of the supporting hand grip on the bearing plate needs to be contacted, the supporting hydraulic cylinder is started to enable the telescopic rod of the supporting hydraulic cylinder to retract into the through hole, so that the supporting hand grip can be turned upwards or downwards when being accepted, and the lifting of the bearing plate cannot be influenced. The support station refers to a position where a telescopic rod of the support hydraulic cylinder can extend out of the through hole and the bearing plate can touch the support hand grip when the bearing plate moves to the height of the support hand grip.

More preferably: one side that supports the tongs and be provided with the holding tank that is used for accomodating the torsional spring with the base is relative.

So set up, realize the installation to the torsional spring.

More preferably: one end of the connecting shaft is connected with a limiting cover used for limiting the supporting hand grip through a bolt.

So set up, will support the tongs through spacing lid and install on the connecting axle.

More preferably: the four safety locks are arranged on two sides of the drop hammer device in a mode that every two safety locks are respectively arranged in a group.

So set up, set up the quantity of sufficient installation lock, have more stable bearing structure.

More preferably: the end of the supporting hand grip is arranged in a V shape.

So set up, the structure that the V-arrangement set up can also form certain limited action to the both sides of accepting the board except can playing the support to accepting the board, and the hammer device can be comparatively stable at normal driving in-process that falls.

More preferably: the three-dimensional scanner comprises a CCD camera, a line laser emitter and an angle sensor, and the CCD camera and the angle sensor are both connected with a data collector.

According to the arrangement, the linear laser transmitters are adopted to be matched with the grid unit type CCD camera to detect data, firstly, the number of the laser transmitters can be effectively reduced, and in addition, grid type scanning can strictly give out an entire column of database of elevation data of each grid unit from large to small, namely sub-millimeter, so that the detection precision can reach 1 millimeter, and the three-dimensional condition of any road surface can be strictly given out. In addition, due to the adoption of the linear laser transmitter, the real vertical section curve and the flatness can be quickly and accurately obtained on the basis of the vertical section elevation data, and the acquired data are input into the computer, so that a three-dimensional image can be directly generated. In the driving process, the angle information detected by the angle sensor corresponds to the bumping condition in the driving process, and the position of the road surface light bar is compensated through the angle information, so that the interference caused by bumping is effectively reduced.

In conclusion, the invention has the following beneficial effects:

1. the flatness and the road surface bearing capacity of the road surface can be detected;

2. when the falling weight deflectometer is not used, the falling weight deflectometer can be limited through the safety lock, so that the falling weight device can be prevented from falling, and meanwhile, the falling weight device can be limited, and the shaking of the falling weight device in the driving process of a vehicle can be reduced.
