A pair of clamping plates clamp the driving motor to preliminarily limit the position of the driving motor and restrict the lateral movement of the driving motor. The upper mounting plate and the lower mounting plate further clamp the driving motor, thereby limiting the upper and lower positions of the driving motor.

[0031] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0032] The present application embodiment discloses a device for measuring rock and soil for engineering geophysical exploration. Figure 1 The device for geotechnical measurement includes a bottom plate 1, and a through hole 11 is opened on the upper surface of the bottom plate 1. A support frame 2 is fixedly connected to the upper surface of the bottom plate 1, and two guide rods 21 are arranged inside the support frame 2. The lower end of each guide rod 21 is fixedly connected to the upper surface of the bottom plate 1, and the upper end of each guide rod 21 is fixedly connected to the inner top wall of the support frame 2. A mounting frame 3 is slidably connected to the two guide rods 21, and a driving motor 4 is connected to the mounting frame 3. The output shaft of the driving motor 4 is vertically arranged downward and coaxially fixedly connected to a drill rod 41.

[0033] The upper surface of the support frame 2 is fixedly connected with a driving member, which is used to drive the mounting frame 3 to slide along the guide rod 21. The driving member includes a driving cylinder 5 fixedly connected to the support frame 2, and the piston rod of the driving cylinder 5 vertically penetrates the support frame 2 downward and is fixedly connected to the mounting frame 3.

[0034] The mounting frame 3 is driven to slide downward along the guide rod 21 by the driving cylinder 5, and the movement of the mounting frame 3 drives the driving cylinder 5 and the drill rod 41 to move downward, and at the same time, the driving motor 4 is started, and the output shaft of the driving motor 4 drives the drill rod 41 to rotate. In this way, the drill rod 41 passes downward through the through opening 11 and rotates into the rock ground.

[0035] Reference Figure 1 and Figure 2The mounting frame 3 includes an upper mounting plate 31 and a lower mounting plate 32. Each end of the upper mounting plate 31 is penetrated by a corresponding guide rod 21 and slides with the guide rod 21. Each end of the lower mounting plate 32 is also penetrated by a corresponding guide rod 21 and slidably connected with the guide rod 21. An elongated hole 321 is provided on the upper surface of the lower mounting plate 32, and one end of the elongated hole 321 horizontally penetrates the lower mounting plate 32. A stopper 33 for limiting the driving motor 4 is fixedly connected to the lower surface of the upper mounting plate 31.

[0036] The upper surface of the drive motor 4 is in close contact with the lower surface of the upper mounting plate 31, and the lower surface of the drive motor 4 is in close contact with the upper surface of the lower mounting plate 32. The drill rod 41 passes through the long hole 321 and is vertically arranged downward. The upper mounting plate 31 is fixedly connected to the piston rod of the drive cylinder 5, and the upper mounting plate 31 and the lower mounting plate 32 are fastened by at least two pairs of bolts and nuts. The upper mounting plate 31 and the lower mounting plate 32 lock the drive motor 4 by clamping the drive motor 4.

[0037] When the drive motor 4 needs to be disassembled and repaired, the upper mounting plate 31 and the lower mounting plate 32 are separated by rotating the bolts and nuts, and then the stopper 33 is adjusted to separate from the drive motor 4. Then, the drive motor 4 is moved along the length direction of the long hole 321, so that the drill rod 41 is separated from the lower mounting plate 32 from the opening at one end of the long hole 321. At this time, the disassembly of the drive motor 4 is completed.

[0038] The stopper 33 includes two fixed blocks 331 fixedly connected to the lower surface of the upper mounting plate 31, a slide bar 332 fixedly connected between the two fixed blocks 331, and a bidirectional lead screw 333 rotatably connected between the two fixed blocks 331, one end of the bidirectional lead screw 333 passes through one of the fixed blocks 331 and is fixedly connected to a hand-held block 334. Two clamping plates 335 are arranged between the two fixed blocks 331, a slide bar 332 passes through each clamping plate 335, and each clamping plate 335 is slidably connected to the slide bar 332. The bidirectional lead screw 333 is threadedly connected to the two clamping plates 335, and the upper surface of each clamping plate 335 is closely attached to the lower surface of the upper mounting plate 31.

[0039] Place the drive motor 4 between the two clamping plates 335, then rotate the hand-held block 334. The rotation of the hand-held block 334 drives the bidirectional screw 333 to rotate. The rotation of the bidirectional screw 333 drives the two clamping plates 335 to clamp the drive motor 4 in a direction close to each other. This makes it easy to limit the drive motor 4 and completes the initial locking of the drive motor 4.

[0040] Each clamping plate 335 includes an arc-shaped plate segment 3351 , and the arc-shaped plate segment 3351 is convenient for better clamping the driving motor 4 .

[0041] When the drive motor 4 needs to be disassembled, the upper mounting plate 31 and the lower mounting plate 32 are adjusted to separate, and then the hand-held block 334 is rotated to move the two clamping plates 335 away from each other to separate from the drive motor 4. Then the drive motor 4 is moved downward, so that the drive motor 4 can be separated from the stopper 33.

[0042] Reference Figure 1 and Figure 3 In order to facilitate the movement of the device, four rollers 6 are installed on the lower surface of the bottom plate 1, and the four rollers 6 are evenly distributed on the bottom plate 1. Four mounting rods 7 are fixedly connected to the lower surface of the bottom plate 1, and a mounting groove 71 is opened on the lower surface of each mounting rod 7. A connecting rod 72 is slidably connected in each mounting groove 71, and the lower end of each connecting rod is connected to a corresponding roller 6. A spring 73 is provided in each mounting groove 71, and one end of the spring 73 is fixedly connected to the bottom wall of the mounting groove 71, and the other end is fixedly connected to the connecting rod 72.

[0043] The arrangement of the spring 73 facilitates the device to pass through complex sections when moving, and facilitates the device to move more smoothly on different ground surfaces.

[0044] In order to facilitate the device to stay at the desired position more stably, a stop assembly 8 is installed on the bottom plate 1. The stop assembly 8 includes a receiving plate 81 located above the bottom plate 1, and the receiving plate 81 is penetrated by the support frame 2 and each guide rod 21. A receiving port 811 is provided on the receiving plate 81, and the receiving port 811 is aligned with the through port 11 to facilitate the passage of the drill rod 41.

[0045] Four support rods 82 are fixedly connected to the bottom surface of the receiving plate 81, each of which vertically penetrates the bottom plate 1 downwards, and a support block 83 is fixedly connected to the lower end of each support rod 82. A stop motor 84 is fixedly connected to the lower surface of the bottom plate 1, and the output shaft of the stop motor 84 is vertically upwards and fixedly connected to a connecting screw 85, which vertically penetrates the bottom plate 1 and is threadedly connected to the receiving plate 81.

[0046] When the device moves to the desired position, the stop motor 84 is started, and the output shaft of the stop motor 84 rotates to drive the connecting screw 85 to rotate, and the connecting screw 85 rotates to drive the receiving plate 81 to move downward, and the receiving plate 81 moves downward to drive each support rod 82 and support block 83 to move downward until each support block 83 is supported on the ground, thereby locking the position of the device.

[0047] A support groove 831 is formed on the lower surface of each support block 83 , and a reinforcement rod 86 is connected to the support groove 831 for damping rotation. One end of the reinforcement rod 86 is a pointed end. The reinforcement rod 86 is arranged horizontally and completely placed inside the support groove 831 .

[0048] When it is necessary to reinforce the connection between the device and the ground, each reinforcement rod 86 is rotated until each reinforcement rod 86 is set in the vertical direction and the tip is located at the lower end of the reinforcement rod 86. At this time, when the support block 83 is driven downward by stopping the motor 84, each reinforcement rod 86 can be gradually inserted into the ground to reinforce the connection between the support block 83 and the ground.

[0049] The implementation principle of the device for geotechnical measurement for engineering geophysical exploration in the embodiment of the present application is: move the device to the desired position, then start the stop motor 84 until each support block 83 contacts the ground, at which time the position of the device is fixed.

[0050] Then start the driving cylinder 5, and start the driving motor 4 at the same time. The piston rod of the driving cylinder 5 drives the mounting frame 3, the driving motor 4 and the drill rod 41 to move downward along the guide rod 21. The drill rod 41 gradually passes through the receiving interface 811 and the through hole 11 and rotates to be inserted into the ground, thereby drilling rock and soil.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
