Description

Technical Field

[0001] This utility model relates to the field of shear wave testing technology, and in particular to a shear wave testing device for stratigraphic division in engineering surveying. Background Technology

[0002] Shear wave testing equipment primarily relies on the propagation characteristics of elastic waves in different media. When a shear wave is generated by an excitation source, these waves propagate through the subsurface medium and are reflected or refracted when they encounter interfaces between strata of different properties. The receiver captures these waveform signals and converts them into electrical signals. By analyzing the signal's arrival time, amplitude variations, and other characteristics, key parameters such as the stratum's thickness, density, and shear modulus can be inferred.

[0003] For example, the shear wave testing equipment disclosed in CN221239081U includes a housing and a top plate. The housing has an internal stabilizing mechanism, a mounting box is fixed to the upper surface of the housing, and a lifting mechanism is located above the housing. A shear wave tester is fixed to the upper surface of the top plate, and a wire-laying device is also fixed to the upper surface of the top plate. The probe body is connected to the outside of the wire-laying device. This shear wave testing equipment, when activated, starts two first motors, causing two connecting rods to drive multiple first gears to rotate, which in turn causes multiple second gears to drive multiple drill rods to rotate. As the drill rods rotate and penetrate the soil, the stability of the entire equipment is improved. The probe body is used to test the wave velocity in the tunnel. By integrating the shear wave tester, wire-laying device, and probe body, the testing efficiency is improved, solving the problem of needing to place components sequentially during testing, which reduces efficiency. However, because this shear wave testing equipment can only place the probe body into the tunnel through the wire-laying device, manual tapping is required when vibration is needed, which is labor-intensive and inconvenient.

[0004] Therefore, a shear wave testing device for engineering surveying and stratigraphy has now been developed that can automatically tap wooden boards, saving manpower and improving testing convenience. Utility Model Content

[0005] To overcome the shortcomings of existing shear wave testing equipment, which can only place the probe body into the tunnel through a wire laying device and requires manual tapping when it is necessary to generate vibration by tapping the wooden board, which is labor-intensive and cumbersome, this utility model provides a shear wave testing device for engineering surveying and stratigraphy that can automatically tap the wooden board, saving manpower and improving the convenience of testing.

[0006] Technical solution: A shear wave testing device for geological stratigraphy in engineering surveying includes an operating table, a first motor, a winding shaft, a cable, a three-component geophone, a shear wave tester, a guiding component, and a striking component. The first motor is connected to the upper rear side of the operating table, and the winding shaft is connected to the output shaft of the first motor. The winding shaft is rotatably connected to the operating table, and a cable is wound on the winding shaft. A three-component geophone is located on the left side of the cable. The shear wave tester is connected to the upper right side of the operating table, and the cable is connected to the shear wave tester. The operating table is equipped with a guiding component that can guide the cable to move and rewind, and a striking component that can strike a wooden board is provided on the operating table.

[0007] In addition, it is particularly preferred that the device also includes a tray, which is connected to the upper left side of the control panel, through which the cable passes.

[0008] Furthermore, it is particularly preferred that the guide assembly includes a belt, a reciprocating screw, and a guide block. The reciprocating screw is rotatably connected to the left side of the operating table. The belt is wound around the reciprocating screw and the winding shaft via a transmission wheel. The guide block is threadedly connected to the reciprocating screw, and the cable passes through the guide block.

[0009] In addition, it is particularly preferred that a limit rod is also included, which is connected to the left side of the control panel. The limit rod is located below the reciprocating lead screw, and the guide block is slidably connected to the limit rod.

[0010] Furthermore, it is particularly preferred that the striking assembly includes a counterweight, a toothed slide bar, a limiting plate, a missing gear, and a second motor. The front of the operating table is connected to two limiting plates, and the toothed slide bar is slidably connected between the limiting plates. The counterweight is connected to the lower side of the toothed slide bar. The upper front of the operating table is connected to the second motor, and the missing gear is connected to the output shaft of the second motor.

[0011] Furthermore, it is particularly preferred that the first motor, the second motor, and the processor are electrically connected via a control module.

[0012] The beneficial effects are as follows: This utility model starts the second motor, drives the missing gear to rotate, and makes the missing gear mesh with the toothed slide rod, which drives the toothed slide rod to move upward on the limit plate, thereby causing the counterweight to move upward. After the missing gear disengages from the toothed slide rod, the counterweight moves downward under the action of gravity to strike the wooden board, thus achieving the effect of automatically striking the wooden board, saving manpower and improving the convenience of testing.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] A shear wave testing device for stratigraphic division in engineering surveying, such as Figures 1-5 As shown, the device includes an operating platform 1, a first motor 2, a take-up shaft 3, a cable 7, a three-component detector 8, a support plate 9, a shear wave tester 10, a guide assembly, and a striking assembly. The first motor 2 is connected to the upper rear side of the operating platform 1. The take-up shaft 3 is connected to the output shaft of the first motor 2 and is rotatably connected to the operating platform 1. The cable 7 is wound on the take-up shaft 3. The three-component detector 8 is located on the left side of the cable 7. The support plate 9 is connected to the upper left side of the operating platform 1, and the cable 7 passes through the support plate 9. The shear wave tester 10 is connected to the upper right side of the operating platform 1, and the cable 7 is connected to the shear wave tester 10. The operating platform 1 is equipped with a guide assembly and a striking assembly.

[0021] like Figures 1-4 As shown, the guide assembly includes a belt 4, a reciprocating screw 5, a limit rod 51, and a guide block 6. The reciprocating screw 5 is rotatably connected to the left side of the operating table 1. The belt 4 is wound around the reciprocating screw 5 and the winding shaft 3 via a transmission wheel. The limit rod 51 is connected to the left side of the operating table 1 and is located below the reciprocating screw 5. The guide block 6 is threadedly connected to the reciprocating screw 5 and is slidably connected to the limit rod 51. The cable 7 passes through the guide block 6.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, the striking assembly includes a counterweight 11, a toothed slide bar 12, a limiting plate 13, a missing gear 14, and a second motor 15. The front of the operating platform 1 is connected to two limiting plates 13, and the toothed slide bar 12 is slidably connected between the limiting plates 13. The counterweight 11 is connected to the lower side of the toothed slide bar 12. The second motor 15 is connected to the upper front side of the operating platform 1. The first motor 2, the second motor 15, and the processor are electrically connected through a control module. The missing gear 14 is connected to the output shaft of the second motor 15.

[0023] When using this utility model, first place the operating table 1 in the shear wave test area, then connect the three-component detector 8 to the cable 7 so that the three-component detector 8 is connected to the shear wave tester 10. Then the processor starts the first motor 2 through the control module, drives the winding shaft 3 to rotate, releases the cable 7, and the support plate 9 guides the cable 7 to put the three-component detector 8 downward into the drilled test hole.

[0024] As the winding shaft 3 rotates, the belt 4 drives the reciprocating screw 5 to rotate, causing the guide block 6 to move back and forth along the limiting rod 51, thereby making the cable 7 evenly unwind and wind up.

[0025] The seismic detector is then electrically connected to the shear wave tester 10. The seismic detector is then placed at a horizontal distance of about 1 to 2 meters from the borehole opening. A wooden board is placed above the seismic detector, with the counterweight 11 positioned above the board. The second motor 15 is then started, causing the missing gear 14 to rotate. This causes the missing gear 14 to mesh with the toothed slide rod 12, moving the toothed slide rod 12 upward on the limiting plate 13. This, in turn, causes the counterweight 11 to move upward. After the missing gear 14 disengages from the toothed slide rod 12, the counterweight 11 moves downward under gravity, striking the wooden board. The data measured by the seismic detector and the three-component geophone 8 are used for engineering survey stratigraphic division. This method automatically strikes the wooden board, saving manpower and improving the convenience of testing.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
