Uniform compaction device for rock stratum in similar simulation experiment

The utility model discloses a rock stratum uniform compaction device in an analog simulation experiment, and belongs to the field of rock stratum analog simulation experiments. Comprising a simulated rock stratum and a light winch, a steel wire rope is arranged in the light winch, a rock stratum simulation test rack is arranged on the simulated rock stratum, the rock stratum simulation test rack comprises two vertical rods and a cross beam arranged between the vertical rods, rail clamping grooves with scales are formed in the vertical rods on the two sides, and fixed pulleys used for adjusting the direction of the steel wire rope are arranged on the cross beam. The fixed pulley is connected with an electromagnet through a load-bearing steel wire rope with one end arranged in the light winch, a gravity plate with the same load of each part of the simulated rock stratum when freely falling above the simulated rock stratum is adsorbed below the electromagnet, and the area of the gravity plate is matched with the
