Background technology:
At present, requirement of engineering such as railway, highway, airport are measured filling compaction density, and sand replacement method is preferably and detection density method commonly used.Sand replacement method has been continued to use for many years in China, sand replacement method principle of work, method of operating are all fairly simple, but main shortcoming is to be subjected to artifical influence factor big, and the test work efficiency is lower, need carry the sand of more amount, and the weighing number of times is more, usually bad grasp during practical operation, and can cause that than mistake, its test speed is slower, measuring accuracy is higher, can not adapt to the requirement of mechanized construction fast detecting.
Summary of the invention:
The utility model is a kind of electromagnetic type soil density analyzer, is the utilization electromagnetic method, designs according to lever principle.
Electromagnetic type soil density analyzer is made up of scale, pointer scale dish, support, electromagnet, soil holding disk, pulley blocks, passive vernier, active vernier, balance screw rod and balance nut etc., and pulley blocks, passive vernier, active vernier and balance nut are located at the side of scale; The support upper right quarter is provided with a scale fixed mount, scale is placed on fixedly in the frame-saw, the activity of scale is limited within the specific limits, the support upper left quarter is provided with a scale supporting-point, the pointer scale dish is placed in herein, the pointer scale dish links to each other by turning joint with support, when pointer refers in central authorities, shows the scale level; The balance nut is located at the scale right-hand member, is used for before measuring usefulness to the scale leveling; Electromagnet is located at left end and is connected by movable bolt with scale, establishes a balance nut at the scale right-hand member, in and electromagnet quality moment that fulcrum is produced.Adjust the leveling nut and make the scale level, the scale value on the scale shows the density of soil, and its value is represented with fractional form.
Wherein, initiatively vernier is connected by the bolt joint with soil holding disk, makes soil holding disk vertical sagging, and initiatively the vernier Lower Half is provided with a linkage levelling screw screw rod;
Pulley blocks is made of two pulleys and an adhesive tape ring, two pulleys are positioned at the two ends of scale, and initiatively vernier and passive vernier are fixed on the adhesive tape ring, when the active vernier moves a certain distance, passive vernier to the opposite direction mobile phase with distance, guarantee that its moment that moves generation cancels out each other;
Linkage levelling screw is positioned at scale left end downside, and shaft passes the initiatively threaded hole of vernier, the tight interlock of screw thread on the linkage levelling screw and threaded hole, and the right-hand member of linkage levelling screw is fixed a leveling nut, can accurately regulate the initiatively position of vernier by rotation leveling nut.
During measurement, need have standard iron sand, substrate and plastic foil, the standard iron sand can adopt prefabricated little steel ball, requires smooth surface, size is even, and its density is demarcated in advance, and its density stabilized property will be got well, substrate requires smooth and thickness will approach, and there is a circular hole in plate central authorities, and area is slightly less than the mouth of testing pits; Plastic foil adopts thinner thickness and pliability material preferably, be used for isolating test pits in soil contact with the direct of iron sand.
The advantage of this electromagnetic type soil density analyzer is: simple in structure, measure accurately, and simple, convenient use, the soil density value can directly be read from scale, and is quick and convenient.
