Description

Technical Field

[0001] The utility model belongs to the technical field of road engineering, and particularly relates to a highway pavement anti-slip detection device. Background Technique

[0002] Road engineering refers to the whole process of planning, designing, constructing, maintaining and managing work taking roads as objects and the engineering entities engaged in; road pavements can be classified as follows according to materials: cement concrete roads, asphalt pavement roads, gravel pavement roads, stabilized crushed stone pavement roads and subways, and the detection of the anti-slip performance of pavements is an important means to ensure road safety. The purpose of detecting the anti-slip performance of pavements is to evaluate the anti-slip ability of pavements and prevent vehicles from skidding and losing control under wet conditions such as rainy days and snowy days. At present, the staff operates the anti-slip performance detection device of the asphalt pavement to detect the pavement performance.

[0003] After retrieval, a patent document with the patent publication number of CN218297974U discloses an anti-slip performance detection device for asphalt pavements, including a device frame and a support bottom plate. The support bottom plate is fixedly installed at the bottom of the device frame. A horizontally arranged sliding rod and a fixed frame are installed inside the device frame. A sliding seat is slidably installed on the sliding rod; the height of the mounting frame can be adjusted, that is, the height of the heating plate can be adjusted. When the support rollers at the bottom of the mounting frame contact the ground, the heating plate can be as close to the ground as possible, so that a more effective and uniform heating function can be carried out on the asphalt pavement when anti-slip performance detection is required, thus simulating the pavement conditions under high-temperature weather. Compared with the existing anti-slip performance detection devices, the heating structure of this utility model can only be close to the ground as much as possible and does not affect the movement of the whole device through the setting of the support rollers, and can provide a heating method with more uniform and effective heating effect, laying a foundation for the actual anti-slip performance detection.

[0004] However, it still has the following disadvantages in actual use:

[0005] For the existing anti-slip performance detection device of asphalt pavements, during use, the height of the detection wheel is adjusted by operating the electric telescopic rod, and the height of the heating plate and the support rollers is adjusted by turning the crank, so that the heating plate is as close to the ground as possible to heat the ground more evenly, but this will increase the operation steps and the workload of the staff;

[0006] 2. For the existing anti-slip performance detection device of asphalt pavements, during use, by starting the water pump, the water in the storage tank is sprayed on the pavement through the spray head, but it is not convenient for the staff to judge the water level in the tank, and it is not convenient for the staff to judge whether water needs to be added to the storage tank, which will cause the water pump to run idly when there is no water in the storage tank, increase the power consumption, and have an adverse effect on the water pump, and even reduce the service life of the water pump.

[0007] To this end, we provide a road surface anti-slip detection device to solve the above problems. Utility Model Content
