Abstract
The utility model relates to an apparatus for taking-in or pushing-out core sample of rock and concrete, composed of shearing box, a backing plate, a push rod, a pair of bevel gears and screw bolts. The utility model is characterized in that the rotation of the gears is changed into the rectilinear motion of the screw bolts. The push rod is penetrated through a hole on a bottom board of the shearing box into the shearing box, causing the sample being lifted in the shearing box with the rotation of the gears. The utility model has the advantages of simple structure and convenient operation. The utility model solves the problem of inconvenient taking-in and pushing-out the sample.
Description
The utility model relates to a kind of sample handler that is used for rock and concrete direct shear test.
Rock and concrete direct shear test are a kind of conventional laboratory test methods in the rock mechanics field, sample to be put into shear box before the test, after finishing, test again sample is taken out from shear box, this work is manual operations always, when specimen size is big, the operation effort is time-consuming, and especially when tightly being stuck in the shear box after the sample shear failure, taking out sample is exactly a very difficult job.
The purpose of this utility model provides a kind of device of shearing sample that is used to load and unload, and can put in shear box easily and therefrom takes out sample, makes simple to operately, laborsaving, increases work efficiency.
For achieving the above object, the utility model is provided with a spiral lifting gear on frame, form by handwheel, bevel-gear sett, screw rod, base plate, push rod etc., rotate handwheel, just can drive bevel gear wheel by bevel pinion and rotate, screwed hole is arranged on the bevel gear wheel, screw rod just is spun in the screwed hole, when bevel gear was rotated, screw rod was just done elevating movement.Base plate is equipped with in the screw rod upper end, and four push rods are arranged on the plate, has four corresponding with it holes to pass for push rod on the base plate of shear box, and a backing plate is arranged in the shear box, and sample just is pressed on the backing plate.When the screw rod lifting, sample just along with together the motion, thereby reach loading and unloading sample purpose.
Most preferred embodiment of the present utility model is seen accompanying drawing.
Fig. 1 shears the front view of sample handler for the spiral post rod type.
Fig. 2 shears the left view of sample handler for the spiral post rod type.
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in the figure, the utility model spiral post rod type shearing sample handler is made up of shear box 1, backing plate 2, push rod 3, roller bearing 4, base plate 5, bevel pinion 6, handwheel 7, bevel gear wheel 8, pinion stand 9, frame 10, screw rod 11 etc.Its characteristics are as follows: a pinion stand 9 is housed on frame 10, bevel-gear sett is housed on the pinion stand, bevel pinion 6 is shaft gears that a level is installed, its axle head is equipped with handwheel 7, bevel gear wheel 8 is vertically installed, its center is threaded the hole, screw rod 11 is spun in this screwed hole, base plate 5 is equipped with in the upper end of screw rod, be fixed with the push rod 3 of four symmetric arrangement on the plate, have four corresponding with it holes on the base plate of shear box 1, push rod can pass these four holes when rising and stretch in the shear box.Be placed with a backing plate 2 in the shear box, sample just is pressed on the backing plate.
When after test is finished, needing to take out sample, shear box 1 is moved to the precalculated position at frame 10 rear portions along the raceway that is made of roller bearing 4, rotate handwheel 7 and drive bevel gear wheel 8 rotations by bevel pinion 6, screw rod 11 just vertically upwards rises, the hole that push rod 3 passes on shear box 1 base plate withstands on the backing plate 2, thereby sample is ejected shear box.Otherwise, in the time of need in shear box, putting sample, earlier backing plate is risen to after the shear box upper end flushes, sample is placed on the backing plate, rotate handwheel then screw rod is descended, sample just enters in the box thereupon.
The utility model has the advantages that: simple in structure, easy to operate, effectively solved the staight scissors examination The loading and unloading problem of sample when testing.
