The utility model provides a safety warning assembly, and relates to the technical field of safety warning. The two ends of the top end of the warning mold are each provided with two threaded grooves. Supporting frames are fixedly installed at the two ends of the warning mold correspondingly. When road surfaces needing to be constructed on two sides of a road are uneven, the warning assembly is pushed to the position, then the warning board faces the outer end, the warning board is large and gives a safety warning to people passing by in advance, meanwhile, surrounding wind blowing can drive the bells to make a sound, people around are reminded to watch the warning board at the position, and the safety of the road is improved. In this way, people around cannot walk from the construction site, and safety warning and advanced protection are provided for people; the problems that due to the fact that construction needs to be conducted on the two sides of a road frequently, safety warning needs to be conducted in advance, otherwise, ankles of people are prone to sprain sprain when people walk on the uneven ground, and people are hurt are solved.

The present invention relates to the field of pipe support testing technology, specifically to an insulated pipe support overall strength displacement overload testing device and method, comprising a bearing base, and also comprising a pipe support base arranged on the upper side of the bearing base, a connecting pipe support being installed on the upper end of the pipe support base, a clamping plate being clamped on the upper side of the bearing base, a rotating shaft being provided through the clamping plate, a connecting gear being clamped and connected to the bottom end of the rotating shaft, and an annular groove being provided on the upper edge of the bearing base. The present invention can perform axial and radial strength tests on the pipe support during the displacement overload test, has low limitations in use, and a high degree of automation, significantly improving the efficiency of testing the insulated pipe support, and can prevent the pipe support from breaking and causing injuries from broken objects during the pipe support displacement overload test, has a good safety protection function, is highly safe to use, and also realizes a step-by-step disassembly function of the displacement overload test structure, so as to facilitate barrier-free maintenance of the test structure.
