Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As Figure 1-3, the invention provides simulating rock stratum in a kind of similarity simulation experiment to hit tight scraping device, it includes Main supporting plate 8, accessory plate 16, weight 3, scrape flat tooth 13, action bars 7, upper sheave 5, lower pulley 10 and steel wire rope 9, main supporting plate 8 On be provided with chute 8a, weight 3 and be provided with neck 3a, neck 3a can be moved up and down freely along chute 8a, and chute 8a On be provided with scale 8b and baffle plate 4, chute 8a bottoms are provided with bolt chute 4b, baffle plate 4 and are provided with fastening bolt 4a, baffle plate 4 in the chute 8a by fastening bolt 4a elastic realization move freely with it is fixed, main supporting plate 8 and the accessory plate 16 it Between upper and lower part be provided be provided with round bar 6, and the round bar 6 on top can along the round bar axis rotate top slide The lower pulley 10 that can be rotated along the axis of the round bar is provided with wheel 5, the round bar 6 of bottom, weight 3 passes through the steel wire rope 9 are connected with the top of the upper sheave 5 and the bottom of the lower pulley 10 successively, the tail of rope of the steel wire rope 9 with it is described The leading portion of action bars 7 is connected, and action bars 7 is connected by carrying bolt 16a with the accessory plate 16, the bottom of the accessory plate 16 It is provided with cylinder 15, cylinder 15 is internally provided with expansion link 12, the lower end of expansion link 12, which is connected with, described scrapes flat tooth 13.
In the present embodiment, the lower end of main supporting plate 8 and accessory plate 16 is provided with card wheel 11, and the card wheel 11 is blocked in same On the side guard plate 2 of one horizontal both sides, side guard plate 2 is arranged on similarity simulation experiment platform 1.Control valve is provided with outside cylinder 15 14, flexible scale 12a is provided with expansion link 12.Action bars 7 is that fulcrum can be stirred freely along the carrying bolt 16a.Card Wheel 11 is 4, and is symmetrical arranged.The present invention realizes the flexible of expansion link by control valve, and then controls to scrape the lifting of flat tooth, Make every layer strike off after height reach predetermined altitude, it is almost 0 to scrape the leading section of flat tooth and the distance of weight horizontal direction, is passed through The displacement of flat tooth is scraped in control, can control the position of the lower backwardness of weight, it is to avoid repetition is hit tight.
When using the present invention, side guard plate 2 is arranged on similarity simulation experiment platform 1, the card wheel 11 of the device is blocked On the side guard plate 2 of same level both sides, baffle plate 4 is adjusted to certain altitude and by bolt chute 4b and fastening spiral shell with reference to scale 8b Bolt 4a fastens baffle plate 4, according to overlay thickness, is incited somebody to action by expansion link 12, cylinder 6 and control valve 14 and with reference to flexible scale 12a Scrape flat tooth 14 and be transferred to corresponding height, material is substantially shakeout, the area of flat tooth upright projection is scraped into according in equipment in aspect end The weight of weight is hit tight with setting height and struck off by preset thickness, and device then is pushed into aspect end, manually operated Bar 7 makes it be pushed using the carrying bolt 16a on accessory plate 16 as fulcrum, by the lower pulley 10 on round bar 6 by steel wire The direction of power from being changed into downward upwards on rope 9, and the direction for then making power by upper sheave 5 changes again, and then makes steel Cord 9 applies the upward power of weight 3, the 8 chute 8a along along main supporting plate of the neck 3a on weight 3 is moved up the default height of arrival After degree is contacted with baffle plate 4, action bars 7 is unclamped, weight is freely declined, material is hit tight, then, promote card wheel 11 as far as possible even Fast slow reach, makes to scrape flat tooth 13 and strikes off laying by preset height, and the critical of the marking is pounded out in the front end of flat tooth 13 to be doctored with laying Stop during edge, carry out next circulation, until another end of aspect, by striking off that last time is hit tight, under then carrying out The work of one laying, it is important to when new laying starts, the flexible scale 12a of adjustment, makes it be adapted with new overlay thickness, adjusts Scale 8b on whole chute makes it equal with the relative altitude of a upper laying, so that its stress is equal.
The present invention by control operation bar, the height of baffle plate, the length of expansion link and scrapes flat tooth, it is possible to achieve each laying and The uniform force for each position being respectively layered, and make each layering smooth and reach preset height, reduce caused by manual operation by mistake Difference, simplifies operation sequence, increases test accuracy, at the same time, the efficiency of experiment can be improved by this device.
