FIELD: mining.SUBSTANCE: invention relates to a device for testing soils by dynamic probing method included in composition of the mobile drilling rig equipment. Device for dynamic probing of soils comprises a probe, string, impact device, drive with displacement facilities, external displacement sensor. Impact device is made in the form of a guide rod with a hammer, having the possibility of interaction with anvil, transmitting impact force to the probe through the string, and configured with movable lever cam and plate. Lifting height limiter is fixed on the guide rod with a possibility to interact with external displacement sensors arranged in the frame. Drive includes a hydraulic motor with drive sprocket coupled with the drive chain with a hook, lifting hammer up to contact of the lever cam with lifting height limiter and releasing it at the lever cam turning and the plate moving extending from the contact with a hook. Guide rod with a hammer and drive chain are located in a composite housing, consisting of the main housing of cylindrical shape for the guide rod with a hammer and the auxiliary housing of rectangular shape to accommodate the drive chain. Main housing is made with a cover on the top, on which the hydraulic cylinder is mounted, connected with drain line of the hydraulic motor, providing supply pressurized oil and pressing the guide rod to the anvil, and by the flange at the bottom. Auxiliary housing end parts are open.EFFECT: technical result consists in improvement of reliability and operating performances of the device, providing the device use in composition of the mobile drilling rig, improvement of the device operation.6 cl, 6 dwg |
