Mechanical frame part of pavement asphalt block flexible damage detector

Abstract

The invention relates to a mechanical frame part of a pavement asphalt block flexible damage detector. A servo motor U is fixed at the top of a grating plate box; a threaded rotating rod piece penetrates through the central position of the grating plate box, and the top of the threaded rotating rod piece is connected with the rotor end of the servo motor U; the threaded rotating rod piece is sleeved with a thread sleeve, and a groove-shaped block is fixed to the back face of the thread sleeve; the groove-shaped block is fixed to the back face of a strip-shaped plate, a workpiece plate block Uis fixed to the front face of the strip-shaped plate, workpiece plate blocks V are fixed to the two tail ends of the workpiece plate block U respectively, a rod piece pipe transversely penetrates through the upper end between the two workpiece plate blocks V, and transmission cylinders U are fixed to the two tail ends of the rod piece pipe respectively. The technical means that an iron core rod isfixed in a heating coil, the heating coil is formed by winding a hollow copper pipe, and cooling liquid capable of circularly flowing back is poured into the hollow copper pipe is adopted, so that the problem of heating of a luminous body is solved; by means of the technical means that the threaded rotating rod piece is sleeved with the thread sleeve, and the groove-shaped block is fixed to the back face of the thread sleeve, the purpose that the horizontal projection angle of a light source is flexible is achieved.

Description

technical field [0001] The invention relates to a mechanical frame part of a flexible damage detector for asphalt block on road surface. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. However, since asphalt is a kind of engineering material with relatively strong plasticity and good ductility, it has the disadvantage of being relatively easy to break. Many reasons for this are due to the substandard mix ratio of asphalt or material problems, so it needs to be passed. Device detection. Contents of the invention [0003] The object of the present invention is to provide a mechanical frame part of a flexible damage d...
