Background technology
Concrete pressure machine is mainly used in the comprcssive strength of the construction material test blocks such as test concrete, cement, engineering brick, refractory material, it is also possible in the test of the comprcssive strength of other nonmetallic materials. existing concrete pressure test device machine measuring accuracy is limited, it is impossible to the actual performance of reactor product well. this concrete pressure owner will by main frame, hydraulic system and load cell etc. form, wherein main frame: main by upper beam, column, adjusting screw and hands wheel, bearing plate, oil cylinder and piston etc. form, equipped with movable ball seat between leading screw end and top board, during operation after top board bottom surface contacts with test specimen end face, can automatically adapt to the trickle gradient of concrete sample short transverse, two planes are made to contact with each other comprehensively, so that degree part uniform force, according to test specimen size, rotatable handwheel and leading screw, suitably to regulate test space, lower platen end face is carved with location wire frame, it is easy to concrete sample is centrally disposed position.
The lower platen of this concrete pressure machine moves by hydraulic oil cylinder driving, during use, first adjust the position of top board, restart oil cylinder so that lower platen moves, so that the test specimen pressurized between upper and lower pressing plate, the sensor being arranged on top board receives pressure signal, the central processing unit being connected with sensor continues to observe the pressurized situation of concrete sample the pressure condition when time of recording breaks, to determine that the maximum of concrete time can bear pressure. The movement having drawbacks in that top board of such scheme is by screw mandrel control, and the movement of lower platen is by oil cylinder control, and the power source so expended is too much so that the structure of whole concrete pressure machine seems complicated, and mechanism is more too fat to move, and installing space is bigger.
Utility model content
This utility model is intended to provide the concrete pressure mechanism for testing of a kind of upper and lower pressing plate shared power source and simple in construction.
Concrete pressure mechanism for testing in this programme, including frame, this frame is provided with the top base being parallel to each other and bottom base, it is provided with column between top base and bottom base, top base is sliding combined with mobile bar, bottom base is sliding combined with and moves down lever, the lower end of upper mobile bar is connected to top board, the lower end moving down lever is connected to lower platen, and described mobile bar side face is provided with tooth bar, and frame is rotatably connected to the driving gear engaged with this tooth bar;Being additionally provided with lever in frame, the right-hand member of lever and upper mobile bar upper end thereof, the left end of lever and the upper end thereof of drive link, the lower end of this drive link is hinged with connecting rod left end, and the right-hand member of this connecting rod is with to move down lever lower end hinged.
Beneficial effect: by arranging tooth bar on upper mobile bar, tooth bar is driven to move down by unique power source and driving gear, so that upper mobile bar moves down, and make downward power reversely become power upwards by lever, so that power upwards is transferred to connecting rod by drive link, it is transferred to again move down lever, make to move down and lever is moved, it is pressed between lower platen and top board thus being placed on the concrete sample moving down in lever, thereby through miscellaneous part (such as sensor, central processing unit) pressure is measured, this mode makes, lower platen has only to a power source can realize relative motion, make concrete sample pressurized, this concrete pressure mechanism for testing simple in construction, energy consumption is relatively low.
Further, described lever passes through hinge with upper mobile bar, lever and drive link, drive link and connecting rod, connecting rod with moving down lever so that interconnective parts can relatively rotate at hinge place.
Further, being connected by movable ball seat between described top board with upper mobile bar, movable ball seat can make top board automatically adapt to the trickle gradient of concrete sample short transverse, so that degree part uniform force.
Further, described lever is connected with frame by lever support, and this lever support and frame are bolted to connection, and connect more firm.
Further, the rear flank of described tooth bar welds with upper mobile bar, connects more firm.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment concrete pressure mechanism for testing.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: top base 1, bottom base 2, top board 3, lower platen 4, movable ball seat 5, upper mobile bar 6, tooth bar 61, driving gear 7, lever 8, lever support 9, drive link 10, connecting rod 11, move down lever 12.
Embodiment concrete pressure mechanism for testing is substantially as shown in Figure 1: concrete pressure mechanism for testing, including frame, this frame is bolted the top base 1, the bottom base 2 that are parallel to each other, is provided with column between top base 1 and bottom base 2. Having vertical upper shaft hole on top base 1, the position that bottom base 2 is relative with this upper shaft hole has equal interference fit in lower shaft hole, upper shaft hole and lower shaft hole sliding bearing.
Upper mobile bar 6 coordinates with the sliding bearing in upper shaft hole, and the lower end of upper mobile bar 6 is connected to top board 3 by movable ball seat 5, and the upper side of upper mobile bar 6 is welded with vertical tooth bar 61. Being combined with driving gear 7 by rolling bearing in frame, this driving gear 7 is connected by shaft coupling with the output shaft of electric rotating machine (this electric rotating machine is arranged in frame), the flank engagement of this driving gear 7 and tooth bar 61. Being bolted lever support 9 in frame, this lever support 9 is hinged with lever 8, the upper end of the right-hand member of this lever 8 and upper mobile bar 6 is by hinge, and the left end of this lever 8 and drive link 10 upper end are also by hinge.
Move down lever 12 to coordinate with the sliding bearing in lower shaft hole, move down the upper end of lever 12 and the plate face of this lower platen 4 of lower platen 4(be carved with location wire frame) bottom surface weld, the lower end moving down lever 12 passes through hinge with connecting rod 11 right-hand member by the lower end of hinge, this connecting rod 11 left end and drive link 10.
The work process of the present embodiment is: be placed in the location wire frame of lower platen 4 by concrete sample test specimen, start electric rotating machine, driving gear 7 is rotated counterclockwise, first tooth bar 61 moves down and drives lever 8 right-hand member to move down, thus the left end of lever 8 upwarps and drives, drive link 10 moves, drive link 10 makes connecting rod 11 move obliquely, be connected with drive link 10 move down lever 12 also with on move, top board 3 moves, concrete sample is pressed between lower platen 4 and top board 3, due on lower platen 4 with pressure transducer, when driving gear 7 continues to rotate counterclockwise, concrete sample occurs broken after reaching the maximum pressure that can bear, the instantaneous pressure that now pressure transducer detects is changed to 0, the central processing unit being connected with pressure transducer detects the pressure value of this instantaneous variation, pressure signal is become the 0 maximum pressure numerical value detected the before maximum force value born as concrete sample.
