Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for preparing rock-like specimens, and in particular relates to a horizontal oscillator auxiliary device for preparing rock-like specimens in a laboratory. Background Art

[0002] During the construction process in geotechnical engineering, mining engineering and other fields, as the excavation depth continues to increase, it is more difficult to directly coring on site. Since the rocks on site are not easy to obtain and the properties of the collected rock samples are not exactly the same, during indoor experiments, rock-like specimens with similar properties to rocks are often made for simulation to provide reference for the site.

[0003] When preparing rock-like specimens and grouting a mold, a laboratory horizontal oscillator is used to vibrate out bubbles in the slurry in the mold, thereby producing a more homogeneous rock-like specimen. Existing horizontal oscillators present the following challenges in preparing rock-like specimens: First, the mold generally needs to be held during oscillation, which requires significant manual effort. Furthermore, the horizontal oscillator generates constant vibrations that can easily injure the hand. Second, the high power of the horizontal oscillator can shake out the slurry in the mold. Existing laboratory horizontal oscillators typically lack dedicated fixtures to ensure stability, making it difficult for a single person to perform grouting according to the mold's internal conditions.

[0004] It can be seen from this that the structure of the horizontal oscillator used in the prior art for preparing rock-like specimens in the laboratory needs to be further improved. Utility Model Content

[0005] The purpose of the utility model is to propose a horizontal oscillator auxiliary device for preparing rock-like specimens in the laboratory, so that the device avoids holding the mold and fixes the mold for oscillation, so that grouting can be carried out in time according to the slurry spillage in the mold during the oscillation process.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] An auxiliary device for a horizontal oscillator used for preparing rock-like specimens in a laboratory, comprising a base, a machine box, a vibration device and an elastic shock absorber;

[0008] The machine box is arranged above the base, and a number of fixing slots for placing the molds are arranged inside the machine box;

[0015] The clamps are arranged on both sides of the fixing groove, the fixing seats are symmetrically arranged on the upper end surface and the lower end surface inside the machine box, and a clamping spring is connected between the clamps and the fixing seats;

[0016] When the mold is placed in the fixing groove, the clamp is pushed to move to both sides, thereby compressing the clamping spring. The clamping spring applies extrusion force to the mold to fix the mold in the fixing groove.

[0017] Preferably, a semi-cylindrical groove is provided on the fixing surface of the clamp in contact with the mold.

[0018] Preferably, there are four shock-absorbing springs, which are respectively arranged at four corners between the base and the box.

[0040] Example:

[0041] like Figures 1 to 3 As shown, the horizontal oscillator auxiliary device for preparing rock-like specimens in the laboratory in this embodiment includes a base 1, a machine box 2, a vibration device 3 and an elastic shock absorber.

[0042] Base 1 is a square frame, positioned at the bottom of the horizontal oscillator auxiliary device. Of course, base 1 can also be other shapes, which will not be described in detail here.

[0043] The machine box 2 is arranged above the base 1. Several fixing grooves 21 for placing molds 5 are provided inside the machine box 2, so that several molds 5 can be placed inside the machine box 2 and multiple specimens can be prepared at the same time, so as to improve the efficiency of preparing rock-like specimens in the laboratory.

[0044] Vibration device 3 is located at the center of the lower end of housing 2 and is used to continuously vibrate mold 5, removing bubbles from the slurry in the mold and producing a more homogeneous rock-like specimen. Vibration device 3 is electrically driven, resulting in a faster vibration rate and a more uniform oscillation effect than manual operation.

[0045] The elastic dampers in this embodiment are damping springs 41, which are used to reduce the spillage of slurry within the mold 5 during oscillation. Four damping springs 41 are provided, one at each of the four corners between the base 1 and the housing 2, to ensure uniform damping. Of course, the number of damping springs 41 is not limited to four.

[0046] A limiting ring 42 is provided at the upper end of the base 1 and the lower end of the housing 2. The two ends of the damping spring 41 are disposed within the limiting ring 42 and respectively abut against the upper end of the base 1 and the lower end of the housing 2. The limiting ring 42 ensures the directionality of the elastic movement of the damping spring 41.

[0047] A clamping assembly 6 is provided inside the fixing groove 21 for assisting in fixing the mold 5 so that the mold 5 has better stability when oscillating.

[0048] There are multiple groups of clamping assemblies 6, each group of clamping assemblies 6 includes a pair of clamps 61 and fixing seats 62 symmetrically arranged at both ends of the clamps, such as Figure 2 、 Figures 4 to 6 shown.

[0049] Among them, the clamp 61 is arranged on both sides of the fixing groove 21, and the clamp 61 adopts a C-shaped structure. A semi-cylindrical groove is provided on the fixing surface where the clamp 61 contacts the mold 5. The shape of the groove is adapted to the side of the mold 5, so that the clamp 61 and the mold 5 have as large a contact area as possible.

[0050] The fixing seat 62 adopts an L-shaped structure. The fixing seat 62 is symmetrically arranged on the upper end surface and the lower end surface inside the machine box 2. A clamping spring 63 is connected between the clamp 61 and the fixing seat 62.

[0051] Of course, the clamp 61 and the fixing seat 62 may also be in other shapes, which will not be described in detail here.

[0052] When the mold 5 is placed in the fixing groove 21 , the side surfaces of the mold 5 push the clamping members 61 to move to both sides, thereby compressing the clamping springs 63 . The clamping springs 63 exert an extrusion force on the mold 5 to fix the mold 5 in the fixing groove 21 .

[0053] In addition, if Figure 2 and Figure 3 As shown, the upper end of the mold 5 is provided with a mold cover 51, and the mold cover 51 is made of rubber. Figure 7 and Figure 8As shown, a grouting hole 52 is opened on the mold cover 51. During the oscillation process, the bubbles of the slurry in the mold 5 are discharged through the grouting hole 52, and grouting can be carried out in time through the grouting hole 52 according to the spillage of the slurry in the mold 5.

[0054] The use and working process of the horizontal oscillator auxiliary device for preparing rock-like specimens in the laboratory in this embodiment are as follows:

[0055] Put the mold cover 51 (with the end where the grouting hole 52 is located facing upward) on the mold 5;

[0056] Place the mold 5 with the mold cover 51 into the case 2 from above the fixing groove 21 and push the mold 5 in until it contacts the lower end surface inside the case 2. At the same time, the side surfaces of the mold 5 push the clamping members 61 to move to both sides, thereby compressing the clamping springs 63. The clamping springs 63 exert an extrusion force on the mold 5, fixing the mold 5 in the fixing groove 21.

[0057] After the mold 5 is fixed, the power is turned on, the vibration device 3 starts to oscillate, and the shock-absorbing spring 41 reduces the spillage of the slurry in the mold 5 during the oscillation process;

[0058] During the process of preparing the rock-like specimen, the bubbles in the slurry in the mold 5 are discharged through the grouting holes 52 . The slurry spillage inside the mold 5 is observed, and grouting is performed in a timely manner through the grouting holes 52 .

[0059] So far, this embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the horizontal oscillator auxiliary device for laboratory preparation of rock-like specimens of the present invention. Of course, the above is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention and should be protected by the present invention.
