Description

Technical Field

[0001] The utility model relates to the technical field of consolidation instruments, in particular to a high-efficiency pneumatic consolidation instrument. Background Art

[0002] An oedometer is an industrial instrument used to measure the compressive properties of soil under different loads and confined conditions. It can perform normal slow consolidation tests and rapid consolidation tests, and measure the initial consolidation pressure and consolidation coefficient. Traditional oedometers are lever-type oedometers, which increase the pressure on soil samples by placing weights to consolidate them. With the development and progress of science and technology, most of the oedometers used now are pneumatic oedometers, which are more convenient to use and produce more accurate test data.

[0003] Most of the currently commonly used pneumatic consolidators can only process a single sample and cannot perform simultaneous detection of multiple samples as needed, which is not conducive to high-efficiency detection. In addition, the angle of the base is fixed. When there is no horizontal surface for placing the base in the use environment, the horizontality of the pneumatic consolidator body cannot be guaranteed, which may affect the experimental results. It can only be placed on a horizontal plane for use, and its scope of application is small. Therefore, those skilled in the art provide a high-efficiency pneumatic consolidator to solve the problems raised in the above background technology. Utility Model Content

[0007] By the above technical solution, by starting the electric push rod, the telescopic end of the electric push rod drives the sliding plate to move up, and at the same time the limit column slides and limits inside the sliding plate, thereby driving the extrusion plates connected on both sides of the sliding plate to move up together, so that the extrusion plates can pass through the opening to push up the movable plate, and under the joint action of the pressure cover, the soil inside the consolidation box can be squeezed and consolidated. By rotating the rotating block, the rotating block drives the threaded rod to rotate, and the threaded rod drives the extrusion plate to move up, so that the extension amount of the upper part of the extrusion plate relative to the sliding plate can be adjusted, so that the distance between the extrusion plate and the movable plate is different, thereby achieving different degrees of pressurization treatment for multiple soil samples, which is convenient for adapting to the consolidation needs of different soils. When the extrusion plate pushes the movable plate to move up and squeezes the sample soil through the pressure cover, the pressure cover will move up and transmit the force to the pressure transmission needle, and under the action of the pressure transmission needle, the transmitted force is detected and displayed by the pressure gauge, which is convenient for the staff to read.

[0008] Furthermore, the adjustment assembly includes a support column, which is arranged at the lower part of the fixed seat, the upper part of the support column is fixedly connected to a turntable, the interior of the turntable is fixedly connected to a connecting shaft, the connecting shaft is rotatably connected to the interior of the fixed seat, a socket is provided inside the turntable, a slot is provided on the front side of the interior of the fixed seat, an insertion rod is provided inside the fixed seat, the insertion rod is provided inside the slot, the lower part of the insertion rod is fixedly connected to a slide, a slide groove is provided inside the fixed seat, the slide groove and the slot are connected, and the lower part of the support column is fixedly connected to the base.

[0009] Through the above technical solution, the insertion rod is pulled out to disengage from the socket of the turntable, and at the same time, the insertion rod drives the slide plate to disengage from the slide groove to release the limit, and the fixed seat is rotated and tilted. When it is rotated to the appropriate position, the insertion rod is slid from the slot and inserted into the designated socket for fixation. The angle of the fixed seat can be adjusted, thereby adjusting the inclination angle of the consolidation instrument body, so that the consolidation instrument body can remain level on the placement plane at different angles, thereby improving the applicability of the pneumatic consolidation instrument.

[0010] Furthermore, the slide plate is slidably connected to the inside of the slide groove.

[0011] According to the above technical solution, the fixed seat can be limited by sliding the slide plate inside the slide groove.

[0012] Furthermore, the limiting posts are slidably connected to both sides of the interior of the sliding plate.

[0013] According to the above technical solution, the sliding plate can be slidably limited by the limiting posts sliding on both sides of the interior of the sliding plate.

[0014] Furthermore, the insertion rod is slidably connected to the inside of the socket.

[0015] Through the above technical solution, the sliding plate can be driven to slide into the sliding groove to be fixed and limited by sliding the insertion rod inside the insertion hole.

[0016] Furthermore, the fixing seat is rotatably connected to the upper part of the supporting column.

[0017] With the above technical solution, the inclination angle of the oedometer body can be adjusted by rotating the fixing seat on the upper part of the support column, thereby improving the application range of the pneumatic oedometer.

[0018] Furthermore, the extrusion plate is slidably connected to the inside of the opening.
