Abstract
The utility model discloses an auxiliary loading and unloading structure for a large-size direct shear test coarse-grained soil sample. The auxiliary loading and unloading structure comprises a large vehicle and a small vehicle, wherein the large vehicle comprises a vehicle support, travelling wheels, a support device and a guide rail, the travelling wheels are installed at the bottom of the vehicle support, a support device is also installed at the bottom of the vehicle support, the guide rail is installed at the top of the vehicle support, the small vehicle comprises a vehicle plate and a guide rail wheel installed at the bottom of the vehicle plate, and the guide rail wheel is installed on the guide rail and matched with the guide rail. According to the auxiliary loading and unloading structure, the difficulty of the disassembly of an existing large-size coarse-grained soil sample is overcome, and the loaded and unloaded soil sample is hoisted from a shear box, so that the soil sample is manufactured outside a rack, the compactness of the soil sample is ensured sufficiently, and the test efficiency is improved.
Description
Technical field
The utility model relates to a kind of loading and unloading supplementary structure, the large-scale direct shear test soil sample loading and unloading of particularly a kind of coarse-grained soil supplementary structure.
Background technology
Coarse grained soil filler is used very extensive in engineering, and coarse-grained soil cutting performance, coarse-grained soil and structure interface Study on shear properties receive much concern under the dynamic and static load action.TJW-800 type coarse-grained soil large-scale direct shear apparatus uses more in the dynamic and static direct shear test of coarse grained soil filler at present.But the large-scale direct shear apparatus soil sample loading and unloading of experimental applications discovery TJW-800 type coarse-grained soil can only be operated in loading frame, cause soil sample loading and unloading inconvenience, and the soil sample packing is difficult to assurance, needs a kind of supplementary structure of design badly and overcomes this difficulty.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art and provides a kind of large-scale direct shear test soil sample of a kind of coarse-grained soil simple in structure, easy to loading and unloading, that improve conventional efficient to load and unload supplementary structure.
The large-scale direct shear test soil sample loading and unloading of a kind of coarse-grained soil supplementary structure; Comprise cart and dolly, said cart comprises kickstand, road wheel, bracing or strutting arrangement and guide rail, and the bottom of said kickstand is equipped with said road wheel; Said kickstand bottom also is equipped with said bracing or strutting arrangement; The top of said kickstand is equipped with guide rail, and said dolly comprises sweep and the guide rail wheel that is installed in said sweep bottom, and said guide rail wheel is installed on the said guide rail and with said guide rail and is complementary.
In the utility model; Said bracing or strutting arrangement comprises adjustable column, regulates seat and pole; Said adjustable column is installed on the said kickstand; Said pole one end is installed on the said adjustable column, and the other end is provided with the back up pad that can be supported on ground, and said adjusting seat is installed on said adjustable column and the said pole.
In the utility model, said guide rail is for adding long guideway, and said guide rail elongated portion is stretched out said kickstand and can be fixed through the guide rail of block and direct shear apparatus.
In the utility model, said kickstand is provided with the fixed head that is connected with direct shear apparatus on the said side that adds long guideway.
Adopt said structure, the utility model adopts the form of cart and dolly combination, through the kickstand of cart; Make the dolly that is installed on the cart guide rail to be connected with direct shear apparatus, therefore overcome the large-scale direct shear apparatus soil sample loading and unloading of existing coarse-grained soil difficulty, make soil sample outside frame, to make through guide rail; Fully guarantee the soil sample packing and improved test efficiency; Through bracing or strutting arrangement, make support that the kickstand of cart can be firm on the ground, through fixed head cart is connected with the frame of direct shear apparatus and fixes; Strengthen the stability of cart, more steady when making dolly on cart, move.

Embodiment
Below in conjunction with accompanying drawing, specify the embodiment of the large-scale direct shear test soil sample loading and unloading of a kind of coarse-grained soil supplementary structure.
The large-scale direct shear test soil sample of a kind of coarse-grained soil loading and unloading supplementary structure is like Fig. 1,2,3, shown in 4, fixed head 1, kickstand, adds long guideway 3, upper padding plate 4, block 6, adjustable column 9, lower bolster 10, regulates seat 11, pole 12 and road wheel 15 and form big bassinet structure.Sweep 13 is formed vehicle structure with guide rail wheel 14.
Said kickstand by upright angle bar 2, support angle bar 5, front and back angle bar 7 and left and right sides angle bar 8 and be welded.Lower bolster 10 is installed in the kickstand bottom, and four road wheels 15 that are made up of industrial castor are installed on the lower bolster 10, and backing plate 4 is installed at the kickstand top, adds long guideway 3 and is installed on the upper padding plate 4.
It is following to unload the soil sample process: after experiment finished, the experiment main engine connecting rod hung suitable height with shear box, promotes cart; With the frame left side alignment of cart and direct shear test machine, regulate adjustable column 9, regulate seat 11 and pole 12, it is concordant with the frame of direct shear test machine to make that cart adds long guideway 3 height; Make shear box weight transmit and drop on ground through pole 12; Connect fixed head 1 and frame, tiling adds long guideway 3 and goes into frame, adopts block 6 fixedly to add long guideway 3.Dolly slowly pushes frame along adding long guideway 3, and shear box is hung on dolly sweep 13, after shear box lands, promotes dolly, sees shear box off along adding long guideway 3, adopts block 6 fixed shear boxes then.Disconnection adds long guideway 3 and is connected with frame, breaks off fixed head 1 and links with frame, loosens adjustable column 9, regulates seat 11 and pole 12, sees soil sample and shear box off through the cart industrial castor, and the completion soil sample is unloaded and put.
The soil sample installation process is following: the shear box of making soil sample is placed on the dolly sweep 13, adopts block 6 fixed shear boxes, promotes industrial castor; Make the left side and the frame right-justification of cart, regulate adjustable column 9, regulate seat 11 and pole 12 that it is concordant with frame to make that cart adds long guideway 3 height; Make shear box weight transmit and drop on ground through pole 12; Connect fixed head 1 and frame, tiling adds long guideway 3 and goes into frame, adopts block 6 fixedly to add long guideway 3.Promote dolly, the guide rail wheel of dolly send shear box to go into frame along adding long guideway 3.The experiment main engine connecting rod hangs sweep 13 with shear box; Disconnection adds long guideway 3 and links with frame; Break off fixed head 1 and link, loosen adjustable column 9, regulate seat 11 and pole 12, see cart and dolly off through the industrial castor of cart with frame; The experiment main engine connecting rod hangs in clipped position with shear box, accomplishes soil sample and installs.
