Problems solved by technology

[0004] The error of traditional measurement methods is ±1mm or even higher. Emerging technologies have not been popularized and used in my country at present, and there are many potential problems. For example, although laser detection equipment has the advantages of strong anti-interference, its detection accuracy will be affected by the number of laser probes and the installation location. Factors such as the lateral offset of the detection vehicle will affect the judgment of the classification of the wrong platform

Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0038] see Figure 1 to Figure 3 , a stage-staggering simulation device for calibrating a stage-staggering detection device, comprising a support base 2, on which two hollow steel plates 3 are connected through electric telescopic rods 4, and each hollow steel plate 3 is passed through four electric telescopic rods 4 It is connected with the support base 2, and there are two grooves on the support base 2. The bottom of the electric telescopic rod 4 is fixed in the groove on the support base 2 through a fixed support, and the top of the electric telescopic rod 4 is passed through a universal ball joint. The support 5 is connected with the four corners of the hollow steel plate 3 to ensure the free displacement of the hollow steel plate 3 in the longitudinal direction. The length of each hollow steel plate 3 is 50cm, the width is 37cm, and the height is 5cm. The horizo...

Abstract

The invention discloses a slab staggering simulation device for calibrating a slab staggering detection device and a use method thereof. The slab staggering simulation device for calibrating the slab staggering detection device comprises a support pedestal, two hollow steel plates used for forming the staggering slab are connected on the support pedestal through the electric flexible rods, each hollow steel plate is connected with the support pedestal through four electric flexible rods, the top of the electric flexible rod is connected with four corners of the hollow steel plate through the universal spherical hinge supports; the slab staggering simulation device further comprises a controller, the controller is connected with the control ends of the electric flexible rods through a data connection wire. The existing slab staggering detection device can be exactly calibrated by the slab staggering simulation device and the existing detection device is improved or calibrated.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a platform error simulation device for calibrating a platform error detection device and a use method thereof. Background technique [0002] Misalignment is one of the main diseases of cement concrete pavement. It not only affects the driving comfort of the pavement, but also greatly shortens the service life of the pavement. Therefore, the detection of the severity of the wrong platform is particularly important in the pavement maintenance work. my country's "Highway Technical Condition Evaluation Standard" (JTGH20-2007) and "Highway Cement Concrete Pavement Maintenance Technical Specifications" (JTJ073.1-2001) will both wrong Unit measurement is an important part of cement concrete pavement detection. [0003] The amount of stagger is the height difference between the adjacent surface boards at the joints. Misalignment disease is classified according to th...
