The invention discloses an industrial CT scanning test system, which comprises a test base, a multi-axis movement rotation table, a ray generation device, an image acquisition device, a fluid pressure loading device and a control device, wherein the multi-axis movement rotation table, the ray generation device, the image acquisition device and the fluid pressure loading device are supported on the test base. According to the present invention, the industrial CT scanning test system uses the fluid pressure loading device so as to reduce the self-weight of the loading device as much as possible and provide the high loading force, such that the requirements of most of the rock material deformation and failure tests can be met; the loading cylinder of the loading device performs the real-time loading on the sample on the sample table of the multi-axis movement rotation table, such that the loading force applied on the rock sample by the loading cylinder can be real-timely regulated according to the test requirements so as to improve the test efficiency; and according to the number of the arranged loading cylinders, the applying of the multi-direction loading force on the sample can be achieved.

The bowl-type medium speed coal mill includes a coal shoot, a separator cap, an inner cone, a separator, a vane wheel unit, a speed reducer, an exhaust valve unit, a door regulator, a Venturi, a side machine body, a milling roll unit, a milling bowl unit, a sealed air manifold and a coal gangue exhaust port. The variable loading spring unit for controlling the loading force is fixed on the separator and connected via pull rod screw to the milling roll unit. The bowl-type medium speed coal mill has high reliability.

The invention discloses a double-vibration-table connection structure comprising a connecting panel, connecting bases and a force transferring structure. The connecting panel is provided with a bolt hole for being connected with a test piece. The upper ends of the two connecting bases are both fixedly connected with the lower side surface of the connecting panel. The connecting bases are provided with connecting holes for being connected with the vibration tables. The side surfaces of the two connecting bases are fixedly connected via the force transferring structure. The upper side surface of the force transferring structure is fixedly connected with the lower side surface of the connecting panel. The double-vibration-table connection structure is used as a connection structure for connecting the vibration tables with the test piece by means of the connecting panel, the connecting bases and the force transferring structure, and can apply the capability of the two vibration tables to the same test piece as a mean for transferring vibration excitation, thereby enhancing the loading capacity of a vibration test.

A test device for the vertical static load test of a single pile under the condition of stable pressurized water. A model box is laid with soil in the box to simulate a site, and a test single pile is buried in the soil in the box. The vertical loading system includes a reaction force frame, a lever , pile driver and weights, the hydraulic loading system includes a water pump, an inlet anti-filter cartridge, an outlet anti-filter cartridge, a force transfer water bag and a counter-pressure plate, the water outlet of the pump is connected to the anti-filter cartridge, and the imported anti-filter cartridge is installed in the model. On the water inlet of the wall of the box, the outlet anti-filter cartridge is installed on the water outlet of the wall of the model box, the top surface of the soil body in the box is laid with a force-transmitting water bag, and a counter-pressure plate is set on the force-transmitting water bag, and the counter-pressure plate is divided into left and right. Some of them are connected to the rotating shaft, and the left and right counter-pressure plates are connected by a screw cap, and the screw cap passes through the test single pile; the data acquisition system includes a displacement meter, which is located on the top of the test single pile, and the displacement meter is connected with the data acquisition instrument. . The invention has good effect, convenient operation, low cost and short time.
