Description

Technical Field

[0001] The invention relates to the technical field of geotechnical testing equipment, in particular to a multifunctional electric compactor and a use method thereof. Background Art

[0002] The compaction test of soil is a basic test in geotechnical engineering. By carrying out the compaction test in accordance with the specifications, the moisture content and dry density of the soil used can be determined, so as to obtain the optimal moisture content and maximum dry density of the soil, laying the foundation for subsequent tests. At present, the improvement of the electric compactor is mainly aimed at noise, preventing soil debris from splashing, and changing the compaction height. For example, the patent with the patent document number CN212432726U discloses a compactor with a soil sample debris collection device, which collects soil sample debris by placing an open collection box above the base of the compactor; the patent with the patent document number CN215178996U discloses a falling compaction device with adjustable height and counterweight, which can freely adjust the compaction height and counterweight; the patent with the patent document number CN218766235U discloses an electric compactor with a protective structure, which provides a protective cover on the outside of the body, and lowers the protective cover when the compaction hammer is working to prevent materials from splashing to the outside of the body, providing certain protection for the workers around the body.

[0003] However, the current electric compactors still have the defects of filling and feeding. The height of the soil layer during layered compaction still needs to be estimated on site by the test personnel. In addition, as the soil is filled in layers, when the soil layer is compacted for the second time, when the compacting hammer rises to the highest point, the height from the soil layer is reduced, resulting in different work done by the compacting hammer when it falls. For example, in response to the problem of "filling defects", the patent document number CN115753281A discloses an electric compactor, in which a material bucket is set above the compactor for feeding, but the material bucket cannot be freely disassembled. Although this shortcoming has been improved to a certain extent, there is still the problem of the non-detachable material bucket, and when feeding, the soil material still causes uneven distribution of soil particle sizes in the soil layer due to the free fall of soil particles. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects of traditional electric compactors, and to provide a multifunctional electric compactor by combining the functions of existing electric compactors in reducing the noise generated during the compaction process, preventing soil chips from splashing, and adjusting the falling height of the compaction hammer.

[0005] The technical scheme for achieving the purpose of the present invention is: a multifunctional electric compactor, comprising a compactor, a compactor hammer, a base rotating shaft, an intelligent control console, a potential energy sensor, a vacuum transparent glass box, a feed pipe, a knob, a feed pipe fixing ring, a compactor base, a telescopic box, a compactor side plate and a motor;

[0006] The aforementioned multifunctional electric compactor has scale lines on the inner wall of the compaction cylinder for quickly and accurately determining the thickness of the soil layer, ensuring that the thickness of each soil layer is consistent, thereby improving the accuracy and repeatability of the test.

[0007] The aforementioned multifunctional electric compactor has the knob fixed by a knob groove at the upper right rear of the vacuum transparent glass box. A strong all-purpose glue is used as the fixing agent. The knob can be freely rotated in the knob groove to change the direction of the lower end of the feed pipe, so that the soil delivery position can be flexibly adjusted according to the test needs, thereby improving the filling efficiency and uniformity.

[0008] The aforementioned multifunctional electric compactor has one end of the knob connected to a fixed iron ring, and the feed pipe can slide back and forth in the iron ring to change the distance between the lower end of the feed pipe and the bottom of the compaction cylinder, thereby accurately controlling the height of the soil material being placed, avoiding problems such as uneven soil layers or poor compaction effects due to inappropriate height.

[0009] The aforementioned multifunctional electric compactor has a potential energy sensor installed in the compacting hammer rod to sense the change in gravitational potential energy when the compacting hammer falls. By monitoring the potential energy change value, the falling height and impact energy of the compacting hammer can be understood in real time, providing accurate data support for the test.

[0010] The aforementioned multifunctional electric compactor, the intelligent control console can be used to accurately adjust the falling height of the compacting hammer by setting different potential energy change sensing values, thereby achieving precise control of the compaction degree of different soil layers, meeting different test requirements, and improving the flexibility and accuracy of the test.

[0011] The aforementioned multifunctional electric compactor, the vacuum transparent glass box is placed above the base of the compactor, which is used to effectively reduce the noise generated during the compaction process, and at the same time prevent the soil debris brought out by the compaction hammer from splashing, thereby protecting the test environment and the safety of the operators and improving the cleanliness and safety of the test.

[0012] The method of using the aforementioned multifunctional electric compactor is as follows:

[0013] 1) Open the door of the vacuum transparent glass box, place and fix the compaction cylinder, connect the base rotating shaft, and close the door of the vacuum transparent glass box;

[0014] 2) Install the feed pipe, and use the fixing ring and the knob to change the position of the feed pipe, so as to fill the soil sample into the compaction cylinder. After the layered filling is completed, remove the feed pipe;

[0015] 3) Turn on the power, turn on the motor switch and the intelligent console switch in turn, set the potential energy change sensing value, and let the console calculate the required drop height of the compacting hammer. Set the corresponding height h1 through the height setting option on the intelligent console, click the compacting button to compact.

[0016] Record the thickness h2 of the soil sample after compaction;

[0017] 4) After the first layer of soil sample is compacted, reset the compacting hammer drop height. When setting the compacting hammer drop height h3 for the second time, the specific setting method is: add the first compacting hammer drop height h1 to the soil layer thickness h2 after the first compaction (i.e. h3 = h1 + h2);

[0018] 5) Before compacting the third layer of soil sample, set the height of the third compacting hammer according to the same height determination method to compact until the end of the test;

[0019] 6) After the compaction test is completed, turn off the intelligent console switch, motor switch, and cut off the power supply in sequence;

[0020] 7) Open the door of the vacuum transparent glass box and take out the compaction cylinder;

[0021] 8) Clean the dirt inside the vacuum transparent glass box and close the door of the vacuum transparent glass box.

[0022] Beneficial effects:

[0023] 1. The multifunctional electric compactor and its use method provided by the present invention are provided with a feeding pipe, which can solve the problem of uneven distribution of soil particles caused by large particles at the bottom and small particles at the top due to free fall when the operator adds materials above the compaction cylinder. The materials are directly added to the bottom of the compaction cylinder through the feeding pipe, which reduces the test error, and the feeding pipe is detachable and does not affect the test.

[0024] 2. In the method for using the multifunctional electric compactor provided by the present invention, the inner wall of the compactor is provided with scale lines, so the thickness of the soil layer can be directly and quickly obtained, and the operator does not need to use a steel ruler brought by the operator to measure when filling the soil material in layers, thus avoiding cumbersome operations and multiple errors, and having the advantages of being accurate, convenient and reducing test errors;

[0025] 3. In the method for using the multifunctional electric compactor provided by the present invention, the potential energy sensor is adjusted to sense the potential energy changes of different values ​​through the intelligent control console, and then the height of the compacting hammer when compacting each layer of soil sample is set through the control console to ensure that when compacting each layer, the height of the highest point of the compacting hammer falling from the soil sample is consistent with the previous one;

[0026] 4.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention is clearly and completely described below in combination with the drawings and embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown:

[0037] The present invention provides a method for using a multifunctional electric compactor, which comprises a compactor (1), a compactor hammer (2), a base rotating shaft (5), an intelligent control console (4), a potential energy sensor (3), a vacuum transparent glass box (8), a material conveying pipe (13), a knob (7), a material conveying pipe fixing ring (6), a compactor base (10), a compactor side plate (9), a compactor hammer telescopic box (12), a side plate motor (11) and a base motor (14).

[0038] The knob groove in the fixing device of the feed pipe (13) is fixed on the glass box (8) by strong glue, and the spherical solid steel knob (7) can rotate freely in the knob groove, and is connected to the feed pipe fixing ring (6) through a connecting rod, so as to drive the feed pipe fixing ring (6) to move back and forth. The feed pipe (13) can move forward and backward in the fixing ring (6) which is slightly larger than its own pipe diameter. Through the orderly cooperation of the knob (7), the feed pipe fixing ring (6) and the feed pipe (13), the discharge port at the lower end of the feed pipe (13) can be adjusted in the position of the compaction cylinder, so as to ensure that the soil particles in each soil layer are the same in size, so as to reduce the test error and improve the accuracy of the test result. In addition, an opening is provided at one place of the feed pipe fixing ring (6), so that the size of the ring diameter can be adjusted to a certain extent, which is more conducive to the installation and removal of the feed pipe (13). The upper pipe mouth of the feed pipe (13) is trumpet-shaped, which is convenient for the staff to fill the soil material.

[0039] The compaction cylinder (1) is placed on the compaction instrument base (10). When filling soil materials, the scale lines on the inner wall of the compaction cylinder (1) are used to quickly and accurately determine the thickness of each soil layer, so that the thickness of each soil layer meets the standard requirements. After the test starts, the side plate motor (11) in the side plate (9) of the compaction instrument is used to rotate the gear on the motor (11), thereby driving the large gear to rotate. The rotation of the large gear in turn drives the gear on the left side of the hammer rod of the compaction hammer (2) to work. Since the gear on the left side of the hammer rod of the compaction hammer (2) is connected to the gear slot on the hammer rod of the compaction hammer (2), the compaction hammer (2) can be moved up and down to compact the soil layer. At the same time, the base motor (14) in the compaction instrument base (10) is used to drive the base rotating shaft (5) to rotate. The rotation of the base rotating shaft (5) drives the compaction cylinder (1) to rotate at a uniform speed on the compaction base (10), thereby ensuring that the soil sample is compacted uniformly at all locations, further improving the accuracy of the test results. After the compaction test is completed, the compaction cylinder (1) is taken out for subsequent tests.

[0040] Before the compaction test officially begins, the required potential energy change sensing value is set through the intelligent control console (4), and the falling height of the compaction hammer (2) required to sense the set potential energy change sensing value is calculated. The height of the compaction hammer (2) to be dropped when the first layer of soil is compacted is set for the first time through the height setting option on the intelligent control console (4). After the first layer is compacted, the height of the compaction hammer (2) is reset to the last compaction hammer drop height plus the thickness of the compacted soil layer through the height setting option on the intelligent control console (4), thereby ensuring that the height of the compaction hammer (2) from the soil layer is consistent when compacting in layers. During the test, the potential energy change value is sensed by the potential energy sensor (3) in the hammer rod of the compaction hammer (2), and the reading is recorded, and the reading is displayed on the display screen of the intelligent control console (4).

[0041] An opening is arranged on the top of the vacuum transparent glass box (8) in the electric compaction instrument for the compaction hammer (2) to move up and down. The vacuum transparent glass box (8) can effectively reduce the noise generated by the compaction hammer (2) contacting the soil sample when it falls, and collects soil debris generated during the compaction process. In addition, a box door is arranged on the right side of the glass box (8) to facilitate the placement and removal of the compaction cylinder (1).

[0042] The method of using this electric compactor is as follows:

[0043] 1. Open the door of the vacuum transparent glass box (8), place and fix the compaction cylinder (1), connect the base rotating shaft (5), and close the door of the vacuum transparent glass box (8);

[0044] 2. Install the material delivery pipe (13), and use the fixing ring (6) and the knob (7) to change the position of the material delivery pipe (13), so as to load the soil sample into the compaction cylinder (1). After the layered loading is completed, remove the material delivery pipe (13);

[0045] 3. Turn on the power supply, turn on the motor (11) switch and the intelligent control console (4) switch in sequence, set the potential energy change sensing value, and let the console calculate the required drop height of the compacting hammer. Set the corresponding height h1 through the height setting option on the intelligent control console, click the compaction button to compact, and record the thickness h2 of the soil sample after compaction.

[0046] 4. After the first layer of soil sample is compacted, reset the compacting hammer drop height. When setting the compacting hammer drop height h3 for the second time, the specific setting method is: add the first compacting hammer drop height h1 to the soil layer thickness h2 after the first compaction (i.e. h3 = h1 + h2);

[0047] 5. Before compacting the third layer of soil sample, set the height of the third compacting hammer according to the same height determination method to compact until the end of the test:

[0048] 6. After the compaction test is completed, turn off the switch of the intelligent control console (4), the switch of the motor (11), and cut off the power supply;

[0049] 7. Open the door of the vacuum transparent glass box (8) and take out the compacting cylinder (1);

[0050] 8. Clean up the dirt in the vacuum transparent glass box (8) and close the door of the vacuum transparent glass box (8).

[0051] Example

[0052] The soil sample used in this example is standard clay with a water content of 20% and a dry density of 1.6 g / cm 3 The specific operation process is as follows:

[0053] 1. Preparation

[0054] Open the door of the vacuum transparent glass box (8), place the compaction cylinder (1) on the compaction instrument base (10), fix it, and connect it to the base rotating shaft (5);

[0055] The door of the vacuum transparent glass box (8) is closed to ensure that the box is in a closed state to reduce noise and soil debris splashing.

[0056] 2 Filling soil sample

[0057] Install the material delivery pipe (13), and adjust the position of the material outlet at the lower end of the material delivery pipe (13) in the compaction cylinder (1) by cooperating with the knob (7) and the material delivery pipe fixing ring (6), so that the soil sample can be evenly filled into the compaction cylinder;

[0058] The standard clay is loaded into the upper pipe opening of the feeding pipe (13), and the trumpet-shaped design thereof is utilized to conveniently and quickly load the soil sample;

[0059] The soil samples are loaded in layers, each layer being about 5 cm thick. After the loading is completed, the feed pipe (13) is removed.

[0060] 3. Set parameters and start compaction

[0061] Turn on the power supply, and turn on the side panel motor (11) switch and the intelligent control console (4) switch in sequence;

[0062] The required potential energy change sensing value is set on the intelligent control console (4), and the falling height of the compacting hammer (2) required to sense the set potential energy change sensing value is calculated according to the properties of the soil sample and the test requirements;

[0063] By using the height setting option on the intelligent control console (4), the height at which the compacting hammer (2) falls when compacting the first soil layer is set for the first time, for example, to 30 cm;

[0064] Click the compaction button on the intelligent control console (4), and the compaction hammer (2) starts to work to compact the first layer of soil sample. The thickness h2 of the soil sample after compaction is recorded, for example, 4.8 cm.

[0065] 4 Layered compaction

[0066] After the first layer of soil sample is compacted, the height of the compacting hammer is reset according to the thickness of the compacted soil layer h2. The specific method is: the height of the first compacting hammer h1 (30 cm) is added to the thickness of the soil layer after the first compaction h2 (4.8 cm), that is, h3 = h1 + h2 = 34.8 cm, and the height is adjusted through the height setting option on the intelligent control console (4).

[0067] The second layer of soil samples is compacted in the same way. Before compacting the third layer of soil samples, the height of the third compacting hammer is set again according to the thickness of the compacted soil layer, and the compaction is continued until all soil samples are compacted layer by layer.

[0068] 5. End the experiment and clean up

[0069] After the compaction test is completed, the intelligent control console (4) switch and the side plate motor (11) switch are turned off in sequence, and the power supply is cut off;

[0070] Open the door of the vacuum transparent glass box (8), take out the compaction cylinder (1), and conduct subsequent test analysis;

[0071] Clean the dirt in the vacuum transparent glass box (8) to ensure that the equipment is clean and tidy, and close the door of the vacuum transparent glass box (8) for next use.
