Description
Technical field
The utility model relates to the device of mine, a kind of tunnel or underground engineering Comprehensive Experiment, relates in particular to a kind of oil hydraulic cylinder that saves on the underground engineering synthesis experiment platform of space-efficient.
Background technique
Along with China's urban construction scale constantly enlarges, the contradiction of urban development and land resources shortage is more and more outstanding in recent years, and the development and use underground space has become the only way which must be passed of urban sustainable development.Underground engineering has complexity and the unpredictability of height.A large amount of practices show: under existing scientific and technological condition, response pattern to some complicated Rock And Soils not yet obtains unified understanding, under making up intricately, have to simplify during engineering model, cause that an engineering difficult problem normally can't calculate comparatively desirable answer by theory under the intricately.Therefore, for some important and complicated underground engineerings, carrying out necessary physical experiments just becomes and a kind ofly can approach the research means of actual conditions.For mine, existing tunnel and underground engineering experimental setup, all hydraulic cylinder is installed in the outside of column or back timber usually, relies on flange in the bottom to be connected with bolt with column or back timber.This structure has taken installing space greatly, makes that steel frame construction easily occurs bending and deformation in the overall dimensions increase, stiffness degradation, loading procedure of equipment; Secondly oil pipe is arranged inconvenience, passes in and out axial arranged along oil hydraulic cylinder of oil pipe, takies large quantity space, can't arrange pipe clamp, easily produces vibration; Again hydraulic cylinder body be exposed at the inner side surface of column or back timber below, especially easily break or bump askew oil hydraulic cylinder in the Preparatory work of experiment stage, affect the job security of oil hydraulic cylinder.
The model utility content
The utility model propose a kind of saving installing space, and hydraulic cylinder works is safe for the deficiency of the problems referred to above, is convenient to simultaneously arrange the oil hydraulic cylinder that efficiently utilizes installing space of oil pipe.
The utility model is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of oil hydraulic cylinder that efficiently utilizes installing space, be installed on the underground engineering experimental setup, described underground engineering experimental setup skin is provided with the support frame of being made by square steel, be welded with the reinforcement steel plate around the surface of described square steel, and described square steel offers perforation, simultaneously all offers Fault Segment with the reinforcement steel plate of described relevant position, aperture to perforation; Described to being installed by welding with the sleeve with little flange in boring a hole, and described little flange internal surface has certain extra coarse degree, simultaneously described little flange with strengthen Plate Welding and fix; Be provided with oil hydraulic cylinder in the described sleeve, the fixed end of described oil hydraulic cylinder by be arranged on locking big nut on the square steel with hydraulic locking cylinder in square steel, and the movable end of described oil hydraulic cylinder stretches out the other end of sleeve; Described oil hydraulic cylinder offers filler opening and oil outlet, and described filler opening and oil outlet are distributed in strengthens the inside and outside both sides of steel plate, described filler opening, oil outlet are connected with oil inlet pipe, oil outlet tube respectively, and described oil inlet pipe, oil outlet tube are close to square steel and are arranged along strengthening steel plate simultaneously.
Further: be provided with flange on the movable end of described oil hydraulic cylinder, and fixed end and locking big nut are threaded connection.
Further: be drilled with on the described locking big nut for several auxiliary holes that insert locking tool rotational lock big nut.
Further: described oil inlet pipe, oil outlet tube are installed on the square steel along strengthening steel plate by pipe clamp.
A kind of oil hydraulic cylinder that efficiently utilizes installing space of the present utility model compared to existing technology, has following beneficial effect:
1. owing to described square steel offers perforation, described to being installed by welding with the sleeve with little flange in boring a hole, be provided with oil hydraulic cylinder in the described sleeve, and the fixed end of described oil hydraulic cylinder by be arranged on locking big nut on the square steel with hydraulic locking cylinder in square steel, therefore the present invention than compacter on the existing equipment structure, overall dimensions is little, rigidity is high, and steel frame construction is difficult for occuring bending and deformation.And since with hydraulic locking cylinder in square steel; greatly reduced the installing space that oil hydraulic cylinder takies; hydraulic locking cylinder is in square steel simultaneously; therefore can avoid that oil hydraulic cylinder is broken or bump askew by other devices (turnover of charging carriage) in the Preparatory work of experiment process; have and protect preferably oil hydraulic cylinder, thereby guaranteed the Security of hydraulic cylinder works.
Since hydraulic locking cylinder in square steel, and described filler opening, oil outlet are connected with oil inlet pipe, oil outlet tube respectively, described oil inlet pipe, oil outlet tube are close to square steel simultaneously along strengthening the steel plate layout simultaneously, therefore hydraulic locking cylinder is beneficial to the layout of oil inlet pipe, oil outlet tube in square steel, reduced to connect oil inlet pipe, the shared space of oil outlet tube, thereby can save the space.And described filler opening, oil outlet are connected with oil inlet pipe, oil outlet tube respectively, described oil inlet pipe, oil outlet tube are close to square steel simultaneously along strengthening the steel plate layout simultaneously, therefore oil inlet pipe, oil outlet tube get arrangement convenience, and be convenient to install pipe clamp, thereby oil inlet pipe, oil outlet tube are firm, are difficult for producing vibration.
