Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a field testing device for roadbed compaction degree used in municipal engineering supervision. Background Technology

[0002] In the field of municipal engineering construction, the roadbed, as the basic structure of the road, is directly related to the road's load-bearing capacity, stability, and service life. Insufficient roadbed compaction can lead to road surface settlement, cracking, and other defects, seriously affecting the road's performance and safety. Therefore, accurately detecting the roadbed compaction is a key aspect of municipal engineering supervision. The ring cutter method, as a traditional and commonly used method for detecting roadbed compaction, is widely used in on-site testing due to its relatively simple operation and low cost.

[0003] The basic principle of the ring cutter method for detecting the compaction degree of roadbed is to use a ring cutter of known volume to cut into the roadbed soil sample, measure the mass of the soil sample inside the ring cutter, calculate the density of the soil sample, and then obtain the compaction degree of the roadbed. However, in the actual on-site testing process of municipal engineering projects, the method is not feasible.

[0004] Existing ring cutter testing devices have many limitations. The construction site environment of municipal engineering projects is complex and diverse. The roadbed surface is often uneven, such as local bulges and depressions, or certain cross slopes and longitudinal slopes. In such cases, when using traditional ring cutter testing devices, the ring cutter can only cut into the soil sample vertically. When the roadbed surface is not horizontal, the vertical cutting of the ring cutter will cause the upper and lower surfaces of the soil sample to be non-parallel, resulting in errors in the measurement of soil sample volume. This, in turn, affects the accuracy of soil sample density and compaction degree calculations. At the same time, when testing on roadbeds with cross slopes, after the ring cutter cuts vertically, the soil sample height on one side is higher than that on the other side, causing a deviation between the actual soil sample volume and the theoretical volume of the ring cutter. Consequently, the test results cannot truly reflect the compaction status of the roadbed. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a field testing device for roadbed compaction degree for municipal engineering supervision. This device can solve the problem that the ring cutter can only be kept vertical when cutting into the soil sample. When the roadbed surface is not horizontal, the vertical cutting of the ring cutter will cause the upper and lower surfaces of the soil sample to be non-parallel, resulting in errors in the measurement of soil sample volume, which in turn affects the accuracy of soil sample density and compaction degree calculation. At the same time, when testing on roadbeds with cross slopes, after the ring cutter is vertically cut in, the soil sample height on one side is higher than that on the other side, and the actual soil sample volume deviates from the theoretical volume of the ring cutter, resulting in the test results not being able to truly reflect the compaction condition of the roadbed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roadbed compaction field testing device for municipal engineering supervision, comprising a base, a sliding mounting seat, a motor and a ring cutter, wherein the base is provided with an angle adjustment component;

[0007] The angle adjustment assembly includes a fixed block, a first movable block, a fixed seat, and a movable support column. The fixed seat is fixedly installed on the upper surface of the base. The lower outer wall of the movable support column is rotatably connected to the upper inner wall of the fixed seat. The fixed block is fixedly installed on the upper surface of the base at the end away from the fixed seat. The lower inner wall of the first movable block is rotatably connected to the upper outer wall of the fixed block. A cylinder is fixedly installed in the groove on the upper surface of the movable support column.

[0008] The motor is fixedly installed inside the mounting groove at the end of the sliding mounting base away from the movable support column. A hydraulic telescopic rod is fixedly installed on the outer wall of the end of the first movable block away from the fixed block. The output end of the hydraulic telescopic rod is fixedly connected to the second movable block. The output end of the motor extends rotatably to the outside of the mounting groove on the sliding mounting base and is fixedly connected to a connecting seat. A fixed guide seat is fixedly connected to the outer wall of the movable support column away from the sliding mounting base. A guide groove is opened on the outer wall of the fixed guide seat. A sliding block is rotatably connected to the inner wall of the end of the second movable block away from the hydraulic telescopic rod. Two T-shaped block grooves are opened on the lower surface of the connecting seat.

[0009] Preferably, the outer walls of the conical blocks on both sides of the sliding mounting base are slidably connected to the corresponding slots of the conical blocks on both sides of the movable support column.

[0010] Preferably, the outer wall of the middle protrusion of the sliding mounting base is slidably connected to the outer wall of the movable support column by opening a groove;

[0011] The cylinder's output end slides into a groove on the outer wall of the movable support column and is fixedly connected to the upper surface of the sliding mounting seat.

[0012] Preferably, the outer wall of the tapered block at the end of the sliding block away from the second movable block is slidably connected to the inside of the guide groove.

[0013] Preferably, the outer walls of the two T-shaped blocks on the upper surface of the ring cutter connecting seat are slidably connected to the interior of the corresponding T-shaped block grooves, and mounting plates are provided on both outer walls of the base.

[0014] Preferably, the ring cutter is mounted on the connecting seat by bolts on the two upper T-blocks engaging with slots opened inside the T-block grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This on-site testing device for roadbed compaction used in municipal engineering supervision moves the second movable block by extending and retracting the hydraulic telescopic rod in the angle adjustment component. The second movable block causes the sliding block to slide in the guide groove of the fixed guide seat. Since the first movable block and the fixed block, as well as the movable support column and the fixed seat, are all rotatably connected, the angle and position of the sliding mounting seat can be precisely adjusted through the synergistic action of these components. This allows the ring cutter to be aligned with the roadbed part to be tested at a suitable angle and position, which effectively improves the practicality and flexibility of the equipment. At the same time, it avoids the error in measuring the volume of the soil sample caused by the vertical cutting of the ring cutter when the roadbed surface is not horizontal, which would result in the upper and lower surfaces of the soil sample not being parallel.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a roadbed compaction field testing device for municipal engineering supervision, including a base 1, a sliding mounting seat 8, a motor 9 and a ring cutter 10;

[0028] The base 1 is equipped with an angle adjustment component;

[0029] The angle adjustment assembly includes a fixed block 2, a first movable block 3, a fixed seat 11, and a movable support column 6. The fixed seat 11 is fixedly installed on the upper surface of the base 1. The lower outer wall of the movable support column 6 is rotatably connected to the upper inner wall of the fixed seat 11. The fixed block 2 is fixedly installed on the upper surface of the base 1 at the end away from the fixed seat 11. The lower inner wall of the first movable block 3 is rotatably connected to the upper outer wall of the fixed block 2. The outer walls of the tapered blocks on both sides of the sliding mounting seat 8 are slidably connected to the corresponding slots of the tapered blocks on both sides of the movable support column 6. A cylinder 7 is fixedly installed inside the groove on the upper surface of the movable support column 6. The outer wall of the protrusion in the middle of the sliding mounting seat 8 is slidably connected to the slot on the outer wall of the movable support column 6. The output end of the cylinder 7 extends slidably into the slot on the outer wall of the movable support column 6 and is fixedly connected to the upper surface of the sliding mounting seat 8. A motor 9 is fixedly installed inside the mounting slot at the end of the sliding mounting seat 8 away from the movable support column 6. The first movable block 3 is rotatably connected to the upper outer wall of the fixed block 2 at the end away from the fixed block 2. A hydraulic telescopic rod 4 is fixedly installed on the outer wall of the end. The output end of the hydraulic telescopic rod 4 is fixedly connected to a second movable block 5. The output end of the motor 9 extends rotatably to the outside of the mounting groove on the sliding mounting seat 8 and is fixedly connected to a connecting seat 15. A fixed guide seat 13 is fixedly connected to the outer wall of the movable support column 6 away from the sliding mounting seat 8. A guide groove 14 is opened on the outer wall of the fixed guide seat 13. A sliding block 12 is rotatably connected to the inner wall of the end of the second movable block 5 away from the hydraulic telescopic rod 4. The outer wall of the tapered block at the end of the sliding block 12 away from the second movable block 5 is slidably connected to the inside of the guide groove 14. Two T-shaped block grooves 16 are opened on the lower surface of the connecting seat 15. The outer walls of the two T-shaped blocks on the upper surface of the ring cutter 10 are slidably connected to the inside of the corresponding T-shaped block grooves 16. Mounting plates are provided on both outer walls of the base 1. The ring cutter 10 is installed on the connecting seat 15 by bolts on the two upper T-shaped blocks and the grooves opened inside the T-shaped block grooves 16.

[0030] Furthermore, when using this device, if on-site testing of the roadbed compaction is required, firstly, based on the actual condition of the roadbed, adjust the working angle of the device using the angle adjustment component, then activate cylinder 7. The output end of cylinder 7 extends and retracts, pushing the sliding mounting seat 8 to slide up and down in the groove opened on the outer wall of the movable support column 6, changing the height of the sliding mounting seat 8. Simultaneously, activate the hydraulic telescopic rod 4. The extension and retraction of the hydraulic telescopic rod 4 drives the second movable block 5 to move. The second movable block 5 drives the sliding block 12 to slide in the guide groove 14 of the fixed guide seat 13. Since the first movable block 3 and the fixed block 2, and the movable support column 6 and the fixed seat 11 are all rotatably connected, the sliding block 12 is rotatably connected in conjunction with these components. The precise adjustment of the angle and position of the mounting base 8 allows the ring cutter 10 to be aligned with the subgrade section to be inspected at a suitable angle and position. After the angle adjustment is completed, the motor 9 is started. The rotation of the motor 9 drives the connecting base 15 to rotate. The connecting base 15 engages with the T-shaped block on the ring cutter 10 through the T-shaped block groove 16, causing the ring cutter 10 to rotate and cut into the subgrade soil for soil sampling. After sampling is completed, the motor 9 is turned off, the ring cutter 10 is removed from the connecting base 15, and the soil sample inside the ring cutter 10 is taken out for subsequent compaction degree testing and analysis. Throughout the entire testing process, the base 1 is fixed to the testing site by the mounting plates on both sides to ensure the stability of the device and provide reliable support for the testing work.

[0031] The hydraulic telescopic rod 4 in the angle adjustment assembly extends and retracts, driving the second movable block 5 to move. The second movable block 5 drives the sliding block 12 to slide within the guide groove 14 of the fixed guide seat 13. Since the first movable block 3 and the fixed block 2, and the movable support column 6 and the fixed seat 11 are all rotatably connected, the angle and position of the sliding mounting seat 8 can be precisely adjusted under the synergistic action of these components. This allows the ring cutter 10 to be aligned with the roadbed part to be inspected at a suitable angle and position, which effectively improves the practicality and flexibility of the equipment. At the same time, it avoids the problem that when the roadbed surface is not horizontal, the vertical cutting of the ring cutter 10 will cause the upper and lower surfaces of the soil sample to be non-parallel, resulting in errors in the measurement of the soil sample volume.

[0032] Structural Description: Base 1: Base 1 is the basic support component of the entire testing device, providing a stable support surface.
