Technical Field
[0001] The utility model relates to the technical field of road surface detection, in particular to a road surface anti-skid detection device for highway tests. Background Art
[0002] With the rapid development of highways and motor vehicles, driving safety has received more and more attention. This issue reflects the field of highway construction, including road surface flatness and anti-skid performance. The pendulum instrument is generally used to measure the anti-skid value of asphalt pavement, markings or other material specimens. It is used to evaluate the anti-skid ability of pavement or pavement material specimens in wet conditions. It is a commonly used test equipment in on-site testing of highway subgrade and pavement.
[0003] At present, during the use of the existing pendulum instrument, when the pendulum arm falls back, personnel are required to reach out and catch the pendulum arm immediately to prevent the pendulum arm from falling back excessively and causing the slippery block at the bottom of the pendulum head to collide with the ground and be damaged. However, in the actual operation process, some operators react slowly due to factors such as lack of experience or nervousness, and fail to catch the pendulum arm in time, resulting in damage to the pendulum head. For this reason, we have designed a road surface anti-skid detection device for highway tests to solve the above-mentioned problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A road surface anti-skid detection device for highway tests comprises a leveling base, a column, a degree dial, a cantilever, a rocker arm and a rocker head, wherein the leveling base is mounted with a column, the degree dial and the cantilever are mounted on both sides of the column respectively, the degree dial is mounted with a rocker arm and a pointer, the bottom end of the rocker arm is mounted with a rocker head, the bottom of the degree dial is mounted with a rocker arm blocking mechanism, the rocker arm blocking mechanism comprises a mounting plate, a socket, a blocking rod, an iron sheet, an annular electromagnet and a spring, the mounting plate is mounted on the bottom end of the degree dial, a socket is provided on the mounting plate, a blocking rod is penetrated through the socket, an iron sheet is mounted on one end of the blocking rod located behind the mounting plate, a spring is sleeved on the blocking rod between the iron sheet and the mounting plate, and an annular electromagnet is mounted on the mounting plate at a position opposite to the iron sheet.
[0007] As a further solution of the utility model: a mobile power source is installed on the leveling base, a switch is installed on the leveling base, the mobile power source is electrically connected to the switch, and the switch is electrically connected to the annular electromagnet.
[0008] As a further solution of the utility model: the leveling base is a triangular base, and a level bubble is arranged on the leveling base.

[0010] As a further solution of the utility model: the hanger includes a kettle rack and a handle, the handle is installed on one side of the kettle rack, and the handle is hung on the cantilever.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model provides a rocker bar blocking mechanism, which can be automatically popped out by a switch control to block the falling rocker bar, to prevent the falling rocker bar from causing the swing head to collide with the ground and be damaged. Compared with the existing blocking method that requires manual hand extension, the utility model only needs to press the switch blocking lever to quickly pop out, which is more convenient to operate and can block more quickly. It is less likely to have the problem of untimely blocking of the rocker bar, effectively reducing the probability of the swing head being hit during the test and extending the service life of the swing head to a certain extent.
[0013] The utility model provides a hanging rack and a kettle, and the kettle is hung on the cantilever through the hanging rack, so that a person can carry the device and the kettle simultaneously with one hand, making the carrying more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
