Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy construction, and in particular to a device for measuring the thickness of earthwork. Background Technology
[0002] The construction quality of water conservancy projects has always been a concern. Earthwork construction is the most important part of water conservancy project construction. Even in the key projects of large concrete dams, a large amount of earthwork construction is required, which is the most important construction project. Earthwork is the basic structure of water conservancy projects, and earthwork backfilling is the most important part of quality control. The key link in the quality control of earthwork backfilling is the loose-lay thickness detection, so a thickness detection device is needed.
[0003] According to a Chinese patent authorization announcement number CN221198265U, a soil thickness measuring device is provided. Four wheels are installed at the four corners of the bottom of the base plate. Each wheel has a height-adjustable support leg installed on its side. A vertically arranged support base is fixedly connected to the top side of the base plate. The support base has graduation lines. A horizontally arranged mounting plate is fixedly connected to the top of the support base. A hydraulic cylinder is fixedly connected to the mounting plate. The free end of the hydraulic cylinder passes vertically through the mounting plate. A motor is fixedly connected to the bottom of the free end of the hydraulic cylinder. A vertically arranged threaded rod capable of entering the soil is fixedly connected to the motor shaft. A spirit level is fixedly connected to the side of the motor. A groove is provided on the side of the support base near the spirit level, and the end of the spirit level is inserted into the groove. A through hole is provided on the base plate to allow the threaded rod to pass through.
[0004] However, when the above-mentioned device measures the thickness of the earthwork, the threaded rod is inserted into the earthwork to complete the measurement. Since the length of the threaded rod is limited, when the earthwork is thick, the threaded rod cannot reach the depth of the earthwork measurement, and it is necessary to replace it with a threaded rod of other lengths, which is quite cumbersome. Utility Model Content
[0005] The purpose of this invention is to provide a soil thickness measuring device. This device has the advantages of being convenient and quick to measure thicker soil layers by extending the detection rod during soil thickness measurement.
[0006] The purpose of this utility model is to provide an earthwork thickness measuring device, including a base plate, a support frame fixedly connected to the surface of the base plate, a main plate that can move up and down slidably connected to the inner wall of one side of the support frame, a lifting mechanism that drives the main plate to rise and fall on one side of the main plate, a limiting rod with a scale groove slidably connected to one side of the main plate, both ends of the limiting rod being fixedly connected to the support frame and the surface of the main plate, a detection rod for thickness measurement fixedly connected to the surface of the main plate, a rotatable extension rod movably connected to the inner wall of the detection rod, a transmission mechanism that drives the extension rod to rotate being installed at one end of the extension rod, a threaded groove being opened on the inner wall of the other end of the extension rod, and an extension rod for extending the extension rod being threadedly connected in the threaded groove, and a length mechanism for measuring the extension length of the extension rod being installed on the surface of the extension rod.
[0007] Furthermore, the bottom of the base plate is fixedly connected to multiple conical columns that stabilize the base plate.
[0008] Furthermore, the lifting mechanism includes a lead screw rotatably connected to one side of the base plate surface and one side of the support frame surface. One end of the lead screw is fixedly connected to a handle that facilitates the rotation of the lead screw. The surface of the lead screw is threadedly connected to one end of the main plate surface, causing the main plate to move up and down along the surface of the limit rod.
[0009] Furthermore, the transmission mechanism includes a timing pulley fixedly connected to one end of the extension rod, a timing belt that drives the timing pulley to rotate meshing on the surface of the timing pulley, and a rotating disk that drives the timing belt to rotate meshing on the inner wall of the other end of the timing belt, and the rotating disk is rotatably connected to one side of the main board surface.
[0010] Furthermore, the length mechanism includes a measuring rod threaded onto the surface of the extension rod, the surface of the measuring rod having a graduated groove, and the measuring rod being slidably connected to the inner wall of the extension rod.
[0011] Furthermore, the length mechanism also includes a display panel fixedly connected to the surface of the motherboard, and the surface of the measuring rod is slidably connected to one side of the display panel surface.
[0012] The working principle and usage principle of this utility model are as follows: Multiple conical columns are inserted into the soil to stabilize the base plate. Rotating the handle causes the lead screw to rotate, which in turn moves the main plate up and down on the surface of the limit rod. Simultaneously, the main plate moves the detection rod downwards, inserting it into the soil. The height of the main plate at the scale groove on the limit rod surface is observed to check the soil thickness. When the soil thickness is significant, rotating the rotating disc causes the synchronous belt drive pulley one to rotate. This pulley one then drives the extension rod to rotate on the inner wall of the detection rod, causing the extension rod to move towards the soil via a threaded connection. The extension rod enters the soil, driving the threaded extension rod on its inner wall into the earthwork. Simultaneously, the extension rod drives the measuring rod, which is threadedly connected to the extension rod, to slide along the inner wall of the extension rod. The measuring rod moves in the opposite direction to the extension rod, causing it to slide along the inner wall of the display panel. The distance traveled by the extension rod is displayed by the scale groove on the surface of the measuring rod, which contacts the upper surface of the display panel. By observing the depth value of the measuring rod and the scale groove value on the surface of the limiting rod, and then adding them together, the thickness of the earthwork can be determined. This allows for convenient and quick measurement of thicker earthworks by extending the measuring rod.
[0013] Compared with existing technologies, the advantages of this utility model are as follows: Multiple conical columns are inserted into the soil to stabilize the base plate. Then, the lifting mechanism is rotated, causing the main board to slide on the surface of the limiting rod. Simultaneously, the main board moves the detection rod downwards, inserting it into the soil. The height of the main board reaching the scale groove on the surface of the limiting rod is observed to determine the soil thickness. When the soil thickness is relatively deep, the transmission mechanism is rotated, causing the extension rod to rotate on the inner wall of the detection rod. This causes the extension rod to drive the threaded extension rod inside the extension rod to enter the soil. Simultaneously, the extension rod drives the length mechanism to display the depth of the extension rod inside the soil. By observing the depth value of the length mechanism and the value of the scale groove on the surface of the limiting rod, the soil thickness is obtained. This facilitates the extension of the detection rod during soil thickness measurement, making it convenient and quick to detect thicker soil sections.
[0014] Compared with the prior art, this utility model has the advantages of being convenient and quick to measure the thickness of earthwork by extending the detection rod.
[0015] Compared with the prior art, this utility model has the advantages of facilitating the detection of soil thickness and facilitating the display of thickness values. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.
[0025] A specific embodiment of this earthwork thickness measuring device, such as... Figure 1-7 As shown, an earthwork thickness measuring device includes a base plate 1, a support frame 2 fixedly connected to the surface of the base plate 1, a main plate 4 that can move up and down slidably connected to the inner wall of one side of the support frame 2, a lifting mechanism that drives the main plate 4 to move up and down installed on one side of the main plate 4, a limiting rod 3 with a scale groove slidably connected to one side of the surface of the main plate 4, both ends of the limiting rod 3 being fixedly connected to the support frame 2 and the surface of the main plate 4, a detection rod 5 that can perform thickness measurement fixedly connected to the surface of the main plate 4, a rotatable extension rod 6 movably connected to the inner wall of the detection rod 5, a transmission mechanism that drives the extension rod 6 to rotate installed at one end of the extension rod 6, a threaded groove 8 opened on the inner wall of the other end of the extension rod 6, and an extension rod 7 that extends the extension rod 6 is threadedly connected in the threaded groove 8, a length mechanism that measures the extension length of the extension rod 6 is installed on the surface of the extension rod 7, and a plurality of conical columns 9 that stabilize the base plate 1 are fixedly connected to the bottom of the base plate 1.
[0026] The above technical solution uses multiple conical columns 9 inserted into the soil to stabilize the base plate 1. Then, the lifting mechanism is rotated, causing the main plate 4 to slide on the surface of the limiting rod 3. Simultaneously, the main plate 4 moves the detection rod 5 downward, inserting it into the soil. The height of the main plate 4 reaching the scale groove on the surface of the limiting rod 3 is observed to check the thickness of the soil. When the soil thickness is relatively deep, the transmission mechanism is rotated to drive the extension rod 6 to rotate on the inner wall of the detection rod 5. This causes the extension rod 6 to drive the extension rod 7, which is threadedly connected to the inner wall of the extension rod 6, into the soil. At the same time, the extension rod 7 drives the length mechanism to display the depth of the extension rod 7 into the soil. By observing the depth value of the length mechanism and the value of the scale groove on the surface of the limiting rod 3, and then adding them together, the thickness of the soil can be obtained. This method facilitates the extension of the detection rod 5 during soil thickness measurement, making it convenient and quick to detect thicker soil sections.
[0027] like Figure 1-7 As shown, the lifting mechanism includes a lead screw 10 rotatably connected to one side of the base plate 1 and one side of the support frame 2. One end of the lead screw 10 is fixedly connected to a handle 11 that facilitates the rotation of the lead screw 10. The surface of the lead screw 10 is threadedly connected to one end of the surface of the main plate 4, which drives the main plate 4 to move up and down along the surface of the limit rod 3.
[0028] By using the above technical solution, rotating the handle 11 causes the lead screw 10 to rotate, which in turn causes the main board 4 to move up and down on the surface of the limit rod 3.
[0029] like Figure 1-7 As shown, the transmission mechanism includes a synchronous pulley 12 fixedly connected to one end of the extension rod 6. A synchronous belt 13 is engaged with the surface of the synchronous pulley 12 to drive the synchronous pulley 12 to rotate. A rotating disk 14 is engaged with the inner wall of the other end of the synchronous belt 13 to drive the synchronous belt 13 to drive the synchronous belt 13. The rotating disk 14 is rotatably connected to one side of the surface of the main board 4.
[0030] By using the above technical solution, rotating the rotating disk 14 causes the synchronous belt 13 to drive the synchronous pulley 12 to rotate, which in turn causes the extension rod 6 to rotate on the inner wall of the detection rod 5.
[0031] like Figure 1-7 As shown, the length mechanism includes a measuring rod 15 threadedly connected to the surface of the extension rod 7. The surface of the measuring rod 15 is provided with a scale groove, and the measuring rod 15 is slidably connected to the inner wall of the extension rod 6. The length mechanism also includes a display panel 16 fixedly connected to the surface of the main board 4, and the surface of the measuring rod 15 is slidably connected to one side of the surface of the display panel 16.
[0032] Through the above technical solution, the extension rod 6 drives the extension rod 7, which is threaded to the inner wall of the extension rod 6, to enter the soil. At the same time, the extension rod 7 drives the measuring rod 15, which is threaded to the extension rod 7, to slide on the inner wall of the extension rod 6. Meanwhile, the measuring rod 15 moves in the opposite direction to the extension rod 7, causing the measuring rod 15 to slide on the inner wall of the display panel 16. The distance moved by the extension rod 7 is displayed by the scale groove on the surface of the measuring rod 15 that contacts the upper surface of the display panel 16.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
