Description

Technical Field

[0001] This utility model relates to the field of roadbed fill compaction degree measurement technology, and in particular to an electromagnetic roadbed fill compaction degree measurement device. Background Technology

[0002] The electromagnetic subgrade fill compaction degree measuring device is an instrument based on the principle of electromagnetic induction to detect the compaction degree of subgrade fill. It is mainly used for rapid, non-destructive testing of fill density in civil engineering projects such as roads and bridges. Its core features are as follows: it assesses the compaction effect by observing changes in the propagation characteristics of electromagnetic waves or high-frequency radio signals in the soil, and can measure soil density, moisture content, and compaction degree without damaging the pavement structure. A typical device, such as the LRK-WH801, uses electrode radio frequency technology to acquire the dielectric properties of subgrade materials in real time.

[0003] An existing electromagnetic roadbed fill compaction degree measuring device requires manual operation by most staff when measuring the compaction degree of the roadbed fill, which affects the efficiency of the work required to test the road surface. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an electromagnetic roadbed fill compaction degree measuring device.

[0005] This utility model is achieved by the following technical solution: an electromagnetic roadbed fill compaction degree measuring device, including a mobile frame, a push handle fixedly connected to the rear end of the mobile frame, a moving wheel rotatably connected to the surface of the mobile frame, auxiliary rods fixedly connected to both the left and right ends of the mobile frame, auxiliary wheels rotatably connected to the surface of the auxiliary rods, and a reinforcing crossbar fixedly connected to the surface of the auxiliary rods.

[0006] An auxiliary bracket is fixedly connected to the top of the mobile frame, and a load-bearing bracket is snapped onto the top of the auxiliary bracket. A reinforcing crossbar is fixedly connected to the surface of the mobile frame, and a limit frame is fixedly connected to the front of the reinforcing crossbar. A hydraulic cylinder is inserted into the inside of the limit frame, and a scale measuring column is fixedly installed at the output end of the hydraulic cylinder.

[0007] As a further improvement to the above scheme, the number of the moving wheels and auxiliary wheels is set to two, and the two moving wheels and auxiliary wheels are symmetrically distributed on the left and right sides with the moving frame as the center.

[0008] With the above technical solution, the two moving wheels and the auxiliary wheels are symmetrically distributed on the left and right sides with the moving frame as the center, forming a balanced support system. This effectively distributes the weight of the equipment and reduces the risk of tilting caused by uneven road surface or unilateral force. Especially when working on soft or sloping roadbeds, it can ensure that the device always remains in a horizontal state and avoid measurement errors.

[0009] As a further improvement to the above solution, the reinforcing crossbar is located at the bottom of the mobile frame, the bearing bracket is fixedly connected to the bottom of the reinforcing crossbar, and the limiting bracket is located on the front of the mobile frame.

[0010] Through the above technical solution, the auxiliary wheel at the bottom of the auxiliary rod and the reinforcing crossbar together form a double support structure. The reinforcing crossbar is located at the bottom of the mobile frame and connects the auxiliary rods on both sides laterally to form a triangular stable frame, which significantly improves the equipment's vibration resistance and prevents high-frequency vibration from interfering with the measurement accuracy.

[0011] As a further improvement to the above solution, the scale measuring column is slidably connected inside the moving frame, and the bottom of the hydraulic cylinder is in contact with the top surface of the support bracket.

[0012] As a further improvement to the above solution, the limiting bracket is located at the top of the support bracket, the support bracket is located at the top of the mobile frame, and the auxiliary bracket is located at the front of the mobile frame.

[0013] Through the above technical solution, the limiting clamp restricts the stroke of the hydraulic cylinder, preventing the scale measuring column from excessively inserting into the roadbed and avoiding equipment damage. The fixed connection between the load-bearing bracket and the reinforcing crossbar provides rigid support for the hydraulic cylinder, ensuring that the direction of force application is always perpendicular and improving the accuracy of measurement data.

[0014] As a further improvement to the above solution, the auxiliary support is located at the bottom of the reinforcing crossbar, and the number of reinforcing crossbars is set to two, which are symmetrically distributed left and right around the moving frame. Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model forms a top protective structure by symmetrically distributing auxiliary supports and reinforcing crossbars on the left and right sides. This structure can prevent damage to the hydraulic cylinder and scale measuring column from external impacts or falling foreign objects during the measurement process. The reinforcing crossbars fix the hydraulic cylinder with limit clips, enhancing the equipment's impact resistance under complex working conditions. The bottom of the hydraulic cylinder contacts the top of the support support, ensuring that the measuring column always moves in a straight line during the application of force, preventing measurement deviations caused by offset.

[0016] This utility model uses a hydraulic cylinder fixed to the front of a reinforcing crossbar by a limiting clip frame. Its output end directly drives a scale measuring column to be vertically inserted into the roadbed. The hydraulic system can provide stable and adjustable downward pressure to simulate the actual compaction process. At the same time, the value of the scale measuring column directly reflects the compaction of the fill, realizing quantitative measurement. Attached Figure Description

By setting the auxiliary support 7 and the reinforcing crossbar 9 to be symmetrically distributed on the left and right, a top protective structure is formed, which can prevent damage to the hydraulic cylinder 11 and the scale measuring column 12 from external impacts or falling foreign objects during the measurement process. The reinforcing crossbar 9 fixes the hydraulic cylinder 11 through the limiting frame 10, which enhances the impact resistance of the equipment under complex working conditions. The bottom of the hydraulic cylinder 11 contacts the top of the load-bearing support 8 to ensure that the measuring column always moves in a straight line during the force application process, preventing measurement deviation caused by offset.

The fixed connection between the bearing bracket 8 and the reinforcing crossbar 9 provides rigid support for the hydraulic cylinder 11, ensuring that the direction of force application is always vertical and improving the accuracy of measurement data.

[0034] The auxiliary support 7 is located at the bottom of the reinforcing crossbar 9. There are two reinforcing crossbars 9, which are symmetrically distributed on the left and right sides with the moving frame 1 as the center. The hydraulic cylinder 11 is fixed to the front of the reinforcing crossbar 9 by the limiting frame 10. Its output end directly drives the scale measuring column 12 to be inserted vertically into the roadbed. The hydraulic system can provide stable and adjustable downward pressure to simulate the actual compaction process. At the same time, the value of the scale measuring column 12 directly reflects the compaction of the fill, realizing quantitative measurement.
