Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy investigation and detection, in particular to a heavy-duty soil compactor with a quick-disassembly structure. Background Art

[0002] Water conservancy survey and testing refers to the survey, measurement, monitoring and evaluation work carried out before, during and after the construction of water conservancy projects. It aims to fully understand the geological landforms, hydrology and water resources, environmental ecology, engineering geology, earthquake geology and other conditions of the water conservancy project construction objects. Since water conservancy projects often involve civil engineering such as roadbeds, dams and channels, the soil density of these projects is crucial to the stability and durability of the projects, so heavy-duty soil compactors are used.

[0003] Heavy soil compaction instrument can be used to measure the mechanical parameters of soil, such as density, compression modulus, shear strength, etc. These parameters are important basis for designing water conservancy projects, evaluating geological conditions and land bearing capacity, etc. It mainly simulates the compaction of soil in actual engineering construction scenarios by repeatedly hammering the soil with heavy objects, thereby determining the physical properties of soil under different compaction conditions.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The current sleeves used for surface sampling of heavy-duty soil compactors are fixed to the equipment. Although the fixation of the samples during the internal hammering process is guaranteed, it is inconvenient to remove the internal samples after the test; 2. Generally speaking, the water content of hydraulic soil is relatively high compared to that of soil on other geological surfaces, and thus moisture is inevitably generated during the test process. However, general compaction equipment lacks a structure for collecting or draining water, which causes certain interference or difficulties in the test caused by moisture. Utility Model Content

In order to achieve the above purpose, the present utility model provides the following technical solutions: A heavy-duty soil compactor with a quick-release structure includes a base, a mortise and tenon is provided on the top of the base, and the mortise and tenon are plug-connected with a tenon, and the tenon is welded to the two ends of the outer wall of the compaction cylinder, and the outer annular shape of the compaction cylinder is fitted and connected with a limiting assembly, and the limiting assembly is welded to the surface of the base, and the internal rotation connection of one side of the base is connected with a gear, and the gear is meshed with a half gear, and the half gear is welded to the bottom of the column through a shaft rod running through the axis center thereof, and the column is rotatably connected to the surface of the base, and the column is provided with a limit assembly inside. There is a hydraulic cylinder, the bottom of which is connected to the top of a compacting hammer by bolts. The compacting hammer is located above the compacting cylinder. The bottom of the compacting cylinder is fitted with a first partition, which is welded to the groove on the surface of the base. The bottom of the first partition is fitted with a load-bearing block. A reinforcement layer is provided on the periphery of the load-bearing block. The four sides of the reinforcement layer are welded to the inner wall of the base. The bottoms of the load-bearing block and the reinforcement layer are respectively welded to the bottom of a second partition, which is welded to the inner wall of the base. A drainage groove is provided at the bottom of the second partition, and the drainage groove is slidably connected to the inside of the base.

[0006] The limiting assembly includes a fixed ring, a left adjusting ring and a right adjusting ring. The fixed ring is welded to one side of the left adjusting ring and the right adjusting ring through a spring provided on its inner wall. The surfaces of the left adjusting ring and the right adjusting ring are provided with a first port and a second port respectively.

[0007] Further preferably, the left adjustment ring and the right adjustment ring form an elastic reset structure through a spring, and the left adjustment ring and the right adjustment ring are respectively slidably connected in the sliding groove inside the fixed ring, and the left adjustment ring and the right adjustment ring are clamped and connected through the first port and the second port.

[0008] Further preferably, the compacting hammer forms a lifting structure above the compacting cylinder through a hydraulic cylinder, and the compacting hammer gradually narrows from the top to the bottom, and the axis points of the compacting hammer and the compacting cylinder are located on the same vertical center line, and a through hole for drainage is opened at the bottom of the compacting cylinder.

[0009] Further preferably, a damping shock absorber is installed on the outer bottom wall of the base, and the half gear forms a rotating structure inside the base through the gear, and the column forms a 90° rotating structure on the surface of the base through the half gear.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the compaction cylinder is installed on the equipment body by means of plug-in connection, which is convenient for taking out the sample, and the addition of a limit assembly improves the stability during the detection process.

The compacting hammer 10 is located above the compacting cylinder 4. The bottom of the compacting cylinder 4 is fitted with a first partition 11, which is welded to the groove on the surface of the base 1. The bottom of the first partition 11 is fitted with a load-bearing block 12. A reinforcing layer 13 is provided on the periphery of the load-bearing block 12. The four sides of the reinforcing layer 13 are welded to the inner wall of the base 1. The bottoms of the load-bearing block 12 and the reinforcing layer 13 are respectively welded to the bottom of the second partition 14. The second partition 14 is welded to the inner wall of the base 1. A drainage groove 15 is provided below the second partition 14, and the drainage groove 15 is slidably connected to the inside of the base 1.

[0023] The limiting assembly 5 includes a fixed ring 501, a left adjusting ring 502 and a right adjusting ring 503. The fixed ring 501 is welded to one side of the left adjusting ring 502 and the right adjusting ring 503 through a spring provided on its inner wall. The surfaces of the left adjusting ring 502 and the right adjusting ring 503 are provided with a first port 504 and a second port 505 respectively.

[0024] In this embodiment, Figure 3As shown, the left adjustment ring 502 and the right adjustment ring 503 form an elastic reset structure through a spring, and the left adjustment ring 502 and the right adjustment ring 503 are respectively slidably connected in the sliding groove inside the fixed ring 501, and at the same time, the left adjustment ring 502 and the right adjustment ring 503 are snap-connected through the first port 504 and the second port 505; compared with the compaction cylinder 4 with a fixed structure, it is installed on the equipment body by a plug-in connection, so that the internal sample can be easily taken out after the detection is completed, and the addition of the limiting component 5 improves the stability of the compaction cylinder 4 during the detection process, and effectively reduces the shaking caused by hammering, and the limiting component 5 is snap-connected through the first port 504 and the second port 505 on the surface to achieve the effect of rapid fixation, and the left adjustment ring 502 and the right adjustment ring 503 will slide and reset due to the internal spring structure when the fixation of the first port 504 and the second port 505 is lost, leaving effective space for the disassembly of the compaction cylinder 4.

[0025] In this embodiment, Figure 1 and Figure 5 As shown, the compacting hammer 10 forms a lifting structure above the compacting cylinder 4 through the hydraulic cylinder 9, and the compacting hammer 10 gradually narrows from the top to the bottom, and the axis points of the compacting hammer 10 and the compacting cylinder 4 are located on the same vertical center line, and a through hole for drainage is opened at the bottom of the compacting cylinder 4; the shape of the compacting hammer 10 can reduce the air resistance during descent and improve the stability of descent, and the axis point of the compacting hammer 10 is aligned with the axis point of the compacting cylinder 4, ensuring that the force applied to the soil sample is vertical and uniform, which helps to avoid deviation or tilt when applying force, thereby ensuring the accuracy and reliability of the test results.

[0026] In this embodiment, Figure 5 As shown, a damping shock absorber is installed on the outer bottom wall of the base 1, and the half gear 7 forms a rotating structure inside the base 1 through the gear 6, and the column 8 is a 90° rotating structure on the surface of the base 1 through the half gear 7; the damping shock absorber can effectively reduce the vibration generated during the compaction process, which helps to maintain the stability of the instrument operation. Generally, the frame that drives the compaction hammer 10 at the top of the compaction cylinder 4 is mostly fixed, and the transmission structure of the gear 6 and the half gear 7 allows the column 8 to rotate 90°. The rotating structure allows the top part of the compaction cylinder 4 to be easily rotated to the side, making the placement of the sample easier, providing convenience for the preparatory work before the test to ensure that the sample is placed in the most suitable position, thereby saving time, and the 90° rotating structure also has an important advantage, that is, each time the column 8 is reset, it can ensure that the axis of the compaction hammer 10 and the compaction cylinder 4 remains consistent, thereby improving the continuous stability and reliability of the equipment during the test.

[0027] In this embodiment, Figure 2 and Figure 4As shown, the first partition 11 and the second partition 14 are composed of a plurality of reinforcing ribs arranged in a cross shape, and the first partition 11 and the second partition 14 are hollow. Since the water content inside the water conservancy soil is relatively large, in order to prevent the internal moisture from affecting the test results, the moisture needs to be drained away by hammering during the test to improve the accuracy of the test data. Due to the drainage holes at the bottom of the compaction cylinder 4, the moisture can be effectively discharged through the hollow structure of the first partition 11 and the second partition 14. In addition, the pressure of the compaction hammer 10 during the pressure application is too large. In order to prevent the hollow structure from lacking stability, the first partition 11 and the second partition 14 are constructed with a plurality of reinforcing ribs arranged in a cross shape. This provides good support for the pressure at the bottom, and the pores formed by the reinforcing ribs are extremely small, which effectively avoids the problem of soil layer loss.

[0028] In this embodiment, Figure 4 As shown, the outer wall of the load-bearing block 12 is provided with annular grooves for drainage, and a groove having the same shape as the load-bearing block 12 but larger in size than the load-bearing block 12 is opened at the axis of the reinforcement layer 13; the load-bearing block 12 is supported under the first partition plate 11 to provide support therefor, while the external reinforcement layer 13 adopts a solid structure, which further improves the stability during the pressure application process, and the gap between the reinforcement layer 13 and the load-bearing block 12 provides a channel for drainage.

[0029] The use method and advantages of the utility model: When the heavy-duty soil compactor with a quick-disassembly structure is used, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first of all, it should be explained that when the device is in use, a laser displacement sensor (model KG01) is provided in the compacting cylinder 4, and a pressure sensor (model ZNLBU) is provided in the compacting hammer 10, and they are respectively connected to an external control system through wires. The control system will transmit the collected data to the computer for analysis through relevant data analysis software. The above are all prior arts. The compacting cylinder 4 is pre-installed, and the tenons 3 on both sides thereof are inserted into the interior of the tenon groove 2, and the compacting cylinder 4 can be fixed on the surface of the base 1. The left adjustment ring 502 and the right adjustment ring 503 are slid and pulled out respectively, and are surrounded and fitted on the outer wall of the compacting cylinder 4, and the compacting cylinder 4 is fixed inside the limit assembly 5 by the engagement of the first port 504 and the second port 505. The inspector places the collected sample inside the compacting cylinder 4, i.e., on the surface of the first partition plate 11, and drives the rear gear 6 of the servo motor to rotate. The lower half gear 7 of the meshing structure rotates to drive the column 8 to rotate 90°. At this time, the compacting cylinder 4 The axis of the compacting cylinder 4 and the compacting hammer 10 on the top are on the same vertical center line. When driven by the external control system hydraulic cylinder 9, the compacting hammer 10 will be pushed down to the inside of the compacting cylinder 4. In the reciprocating lifting process, the internal soil sample is hammered, and the moisture in the sample will flow through the first partition 11, the drainage groove on the surface of the load-bearing block 12, and finally flow into the drainage groove 15 from the second partition 14. The soil free of moisture can improve the data results of the test. After the test is completed, the drainage groove 15 can slide to extract and dump the internal sewage. After the test is completed, the servo motor is reversed to make the gear 6 and the half gear 7 drive the column 8 to rotate again, so that a larger space is reserved at the top of the compacting cylinder 4 for cleaning the sample. After the first port 504 and the second port 505 are separated, the left adjustment ring 502 and the right adjustment ring 503 are elastically reset, and a part of the sliding will shrink into the sliding groove of the fixing ring 501. The compacting cylinder 4 can be lifted to separate the tenon 3 from the inside of the tenon groove 2.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
