Description

Connecting device of road transverse force coefficient detection equipment

Technical Field

The application relates to the technical field, in particular to a connecting device of road transverse force coefficient detection equipment.

Background

The road transverse force coefficient detection is generally carried out by using standard friction coefficient measuring equipment, wherein the measuring wheel and the driving direction are 7.5-20 degrees, and when the road is driven on a wet road at a certain speed, the ratio of the lateral friction force born by the test wheel to the load applied on the test wheel is the transverse force coefficient of the road section, so that the anti-skid performance of the road is evaluated.

In the above detection process, the detection device is not driven by power, and all the detection device runs under the traction of the traction device, and meanwhile, in order to achieve the detection condition, the road surface needs to be subjected to wet treatment before detection, so that vehicles such as a sprinkler are generally used as the traction device. The traction equipment does not have a special installation position for connecting the detection equipment, and the common installation mode is to fixedly connect the detection equipment on the traction equipment in a welding mode so as to form stable and rigid connection. However, in most projects, the road transverse force coefficient and other road parameters are detected by checking, the sprinkler is used as traction equipment in a welding mode to cause the loss of the sprinkler, for example, repeated welding and disassembly on a bumper and a guardrail of the sprinkler can lead to weakening of protection capability, the welding and disassembly processes are complicated, more conditions are required to be realized, the detection working efficiency is reduced, and the sprinkler also needs to be negotiated with a renter under the condition that the sprinkler is in a renting property, so that the economic cost is increased, the most critical is that the relative position between the detection equipment and the traction equipment is fixed due to the connection of the welding mode, and errors are generated during detection due to the fact that no high redundancy or adjustment space is available when the sprinkler travels on different road conditions, so that the accuracy of a measurement result is affected.
