Traditional experimental setups often have many limitations when it comes to loading compartmentalized model boxes.

[0003] With the continuous development of engineering construction and the gradual deepening of geological research, the application of compartmentalized model boxes or test blocks requiring multi-directional loading is becoming increasingly widespread in simulating complex geological structures and geotechnical engineering problems. However, existing experimental devices have difficulty meeting these loading requirements when performing multi-directional loading.

[0004] For example, the Chinese utility model document with document number CN204594786U records a horizontal loading device for a geotechnical model box.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0035] The utility model provides an experimental device suitable for multi-directional loading. Three door-type frames are set, including a longitudinal door-type frame and two transverse door-type frames arranged perpendicular to the longitudinal door-type frame. Each door-type frame is provided with a loading mechanism, wherein the force application directions of the first loading mechanism, the second loading mechanism, and the third loading mechanism are perpendicular to each other, so as to meet the experimental requirements of multiple force application directions in complex geological and rock and soil research.

[0036] Example 1

[0037] like Figure 1-4 As shown, the experimental device suitable for multi-directional loading includes a longitudinal portal frame 1 , a first transverse portal frame 2 , a second transverse portal frame 3 and a support base 4 .

[0038] The longitudinal door frame 1 has two first columns 101 and a first crossbeam 102. The two first columns 101 are arranged vertically. The first crossbeam 102 is arranged on the top of the two first columns 101 and is fixedly connected to the two first columns 101. The first loading mechanism 103 is respectively arranged on the inner side surfaces opposite to each other of the two first columns 101. Figure 3Taking the illustrated structural arrangement as an example, the first loading mechanism 103 applies force in a horizontally extending direction. Of the two first loading mechanisms 103, the left first loading mechanism 103 applies force horizontally to the right, while the right first loading mechanism 103 applies force horizontally to the left. A second loading mechanism 104 is provided at the bottom of the first crossbeam 102. The second loading mechanism 104 applies force in an up-and-down extending direction, specifically, in this case, the second loading mechanism 104 applies force vertically downward.

[0039] The first transverse portal frame 2 has two second columns 201 and a second crossbeam 202. The second crossbeam 202 is arranged above the first crossbeam 102 and perpendicular to the first crossbeam 102. The two second columns 201 are both arranged vertically. The second crossbeam 202 is arranged on the top of the two second columns 201 and fixedly connected to the two second columns 201. Third loading mechanisms 203 are respectively provided on the opposing inner side surfaces of the two second columns 201. The force application direction of the third loading mechanisms 203 is a front-to-back extension direction. Of the two third loading mechanisms 203, the force application direction of the front third loading mechanism 203 is horizontally backward, and the force application direction of the rear third loading mechanism 203 is horizontally forward.

[0040] The second transverse portal frame 3 has two third columns 301 and a third crossbeam 302. The third crossbeam 302 is arranged above the first crossbeam 102 and perpendicular to the first crossbeam 102. The two third columns 301 are both arranged vertically. The third crossbeam 302 is arranged on top of the two third columns 301 and fixedly connected to the two third columns 301. The third loading mechanism 203 is respectively provided on the opposing inner side surfaces of the two third columns 301. The third loading mechanism 203 here cooperates with the third loading mechanism 203 on the second transverse portal frame 3 to apply force at multiple fore-aft points, which is used for experiments requiring the simultaneous application of multiple fore-aft pressures.

[0041] like Figure 5 As shown, the structures of all the above loading mechanisms are the same (the first loading mechanism 103, the second loading mechanism 104, and the third loading mechanism 203), and all include a mounting base 8 and a hydraulic cylinder loading component 9. A pressure plate 10 for contacting the surface to be pressurized is provided at the end of the hydraulic cylinder loading component 9, and the mounting base 8 is used to install the loading structure in the corresponding position.

[0042] In addition, each mounting base 8 has a hydraulic cylinder loading component 9 at both ends.

[0043] The support base 4 is provided below the first beam 102 for supporting the object 5 to be pressurized. Specifically, the support base 4 includes a scissor-bracing lifting mechanism 401, on top of which a support plate 402 is provided. During the experiment, part or all of the object 5 to be pressurized is placed on the support base 4.

[0044] Furthermore, to meet the requirements of experiments requiring bottom pressure, the second transverse portal frame 3 also includes a fourth crossbeam 303. The fourth crossbeam 303 is disposed between and fixedly connected to the two third uprights 301. The fourth crossbeam 303 is close to the bottom ends of the third uprights 301, and a second loading mechanism 104 is disposed on the top surface of the fourth crossbeam 303. In this case, the force applied by the second loading mechanism 104 on the fourth crossbeam 303 is vertically upward.

[0045] Furthermore, to flexibly adjust the force application position so that the experimental device can be used to apply force to the vertical side of objects 5 of varying lengths, the tops of the first transverse door-shaped frame 2 and the second transverse door-shaped frame 3 are slidably engaged with the first transverse beam 102 along the longitudinal extension direction of the first transverse beam 102 via a sliding mechanism 6. This allows the force application position of the third loading mechanism 203 to be varied for objects 5 of varying lengths by adjusting the specific positions of the first transverse door-shaped frame 2 and the second transverse door-shaped frame 3.

[0046] Furthermore, to enable this experimental device to accommodate the top surface forces of objects 5 of varying lengths, a second loading mechanism 104 at the bottom of the first beam 102 slides with the first beam 102 along the length of the first beam 102 via a sliding mechanism 6. This allows the force application location of the second loading mechanism 104 to be varied by adjusting its position on the first beam 102. Furthermore, multiple second loading mechanisms 104 can be provided to accommodate experiments requiring pressure on multiple top surfaces.

[0047] Furthermore, to enable the experimental device to accommodate vertical side forces on objects 5 of varying thickness, the third loading mechanisms 203 on the first transverse portal frame 2 are slidably engaged with the corresponding second upright posts 201 along the lengthwise extension of the second upright posts 201 via the sliding mechanisms 6. Simultaneously, to accommodate the varying force requirements of different vertical side force-bearing regions, the third loading mechanisms 203 on the second transverse portal frame 3 are slidably engaged with the corresponding third upright posts 301 along the lengthwise extension of the third upright posts 301 via the sliding mechanisms 6.

[0048] Furthermore, in order to make the experimental device suitable for applying force to the bottom surfaces of objects 5 to be pressed of different widths, the second loading mechanism 104 provided on the fourth beam 303 is slidably matched with the fourth beam 303 along the length extension direction of the fourth beam 303 through the sliding mechanism 6.

[0049] In this embodiment, all the sliding mechanisms 6 are electric guide rails, and the mounting bases 8 of the loading mechanisms are mounted on the electric guide rails, which drive the loading mechanisms by driving the mounting bases 8. In other embodiments, the sliding mechanisms 6 may also be ball screw driven structures.

[0050] Furthermore, in order to reduce the driving burden of the sliding mechanism 6 on the first crossbeam 102, moving wheels 7 are provided at the bottom of the first transverse portal frame 2 and the second transverse portal frame 3. The moving wheels 7 may have a self-locking mechanism. When the positions of the first transverse portal frame 2 and the second transverse portal frame 3 are fixed, the moving wheels 7 are further locked by the self-locking mechanism to ensure the stability of the force applied by the third loading mechanism 203.

[0051] It can be seen from the above overall technical solution that all the above loading mechanisms can at least partially cooperate and apply pressure at the same time to meet complex force application needs.

[0052] Taking a test block or model box with a fault in the middle as an example, the operating steps of this device are as follows:

[0053] The first step is to design a divided model box or a simulation test block that meets the requirements as the object to be pressurized according to the fault type, fault dip, fracture zone thickness and similarity ratio of each part.

[0054] Next, adjust the height of the support base 4 and the second loading mechanism 104 on the fourth beam 303 to a uniform, appropriate height based on the size of the object 5 to be pressed. Secure the lower moving wheels 7 of the second transverse portal frame 3. Place the object 5 to be pressed on the support base 4 and the second loading mechanism 104 on the fourth beam 303, with the left side resting on the support base 4 and the right side resting on the second loading mechanism 104.

[0055] In the third step, the loading mechanism on the first transverse door frame 2 and the second transverse door frame 3 , that is, one of the first columns 101 , is brought into contact with the designated position of the object 5 to be pressed.

[0056] The fourth step is to start the driving device of the loading mechanism.

[0057] The fifth step is to observe the loading conditions and analyze the stress and deformation of the combined fault.

[0058] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
