Description
Technical Field
The utility model relates to a hydraulic pressure pillow, concretely relates to hydraulic pressure pillow suitable for nonparallel loading face.
Background
In the fields of geotechnical tests, engineering detection and the like, the hydraulic ram is a common loading measuring device, however, the loading hydraulic ram and the force-measuring hydraulic ram can only be used for special boundary conditions of parallel surfaces.
In the loading process of the hydraulic ram, along with the loading, the situation that the loading surface develops from parallel to unparallel and the angle is larger and larger often occurs. If the hydraulic ram on the current market is used, the eccentric situation can occur, so that the test fails, the hydraulic ram is damaged, and other adverse effects are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, not enough to current hydraulic pressure pillow inadaptation unparallel loading face measurement provides a simple structure, is applicable to the loading hydraulic pressure pillow of unparallel loading face.
In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the utility model provides a hydraulic ram suitable for nonparallel loading face, includes the pressure cell sealed all around, the inner chamber of pressure cell sets up to the oil bin, just set up the oil inlet nozzle and the play oil nozzle of intercommunication oil bin on the pressure cell, the last fixed surface of pressure cell installs the biography power board, the biography power board is the wedge-shaped body that the upper surface has an inclination.
The dowel plate is made for steel, just the dowel plate is the polylith, and the upper surface of every dowel plate has different inclinations, during the use, chooses for use the dowel plate at different inclinations according to the condition.
In order to further ensure the sealing of the pressure box, the periphery of the pressure box is tightly wrapped by a high-pressure sealing soft sleeve, and the high-pressure sealing soft sleeve is made of high-strength flexible materials.
The pressure box is formed by stamping two steel plates which are arranged in parallel from top to bottom at one time.
The force transmission plate is connected with the pressure box into a whole through a bolt.
In order to facilitate the supply of hydraulic oil, the oil inlet nozzle and the oil outlet nozzle are externally connected with an oil pump through a high-pressure oil pipe.
The high-pressure sealing soft sleeve needs to have enough strength and proper ductility, and needs to have safety and stability under high pressure, and the high-pressure sealing soft sleeve and the junction of the oil inlet nozzle and the oil outlet nozzle need to guarantee enough strength and leakproofness.
The utility model discloses an assembled the wedge form biography power board that has certain inclination at the top of pressure cell, make the utility model is suitable for a measurement of non-parallel loading face, and simple structure, stable performance, the small and exquisite light characteristics of ability full play hydraulic pillow.
