DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 7 As shown, a rock and soil detection and soil taking device for hydropower engineering tunnel excavation provided by an embodiment of the present invention includes a base 101, a vertical plate 102 is fixedly provided on the upper surface of the base 101, a mounting plate 103 is fixedly provided on the top of the vertical plate 102, an impact plate 104 is sleeved on the outer side of the vertical plate 102, a side plate 105 is fixedly provided on the outer side of the base 101, and a telescopic cylinder 106 is fixedly provided on the outer wall of the side plate 105, and a moving wheel 107 is provided at the telescopic end of the telescopic cylinder 106 The outer wall of the base 101 is also provided with a soil taking port, and also includes: an impact mechanism, which is arranged on the upper surface of the impact plate 104 and is used to impact the sampling tube downward; a limiting mechanism, which is arranged above the impact plate 104 and is used to limit the position of the impact plate 104; a pulling mechanism, which is arranged above the base 101 and is used to pull the sampling tube out of the soil after the sampling tube has taken soil; a restraining mechanism, which is arranged on the outer side of the base 101 and is used to maintain the sampling tube in a vertical state and inserted into the soil.

[0025] When the device moves to the position to be taken soil, the position of the base 101 can be adjusted by telescoping the telescopic cylinder 106 so that the base 101 remains horizontal. Then the sampling tube can be placed in the soil taking opening on the base 101, and the sampling tube can be kept vertical under the action of the binding mechanism. At this time, the limit of the impact plate 104 by the limiting mechanism can be released first, and then the impact plate 104 can be made to impact the sampling tube under the action of the impact mechanism, so as to drive the sampling tube to move downward so that the sampling tube is inserted into the position to be taken soil. After the sampling tube is inserted, other sampling tubes can be spliced ​​with the sampling tube inserted into the soil, and the sampling tube can be impacted again by the impact plate 104 until the sampling tube reaches the appropriate sampling point, effectively realizing the sampling operation of soils of different depths. When the sampling tube needs to be pulled out after the sampling is completed, the sampling tube can be directly pulled out of the soil with the help of the pulling mechanism, effectively realizing the integrated plug-in and pull-out operation of the sampling tube, thereby improving the sampling efficiency and achieving better use effect.

[0026] As an embodiment of the present invention, please refer to Figure 2 and Figure 3 The impact mechanism includes a vertical plate 201 fixedly arranged on the upper surface of the impact plate 104, an impact block 202 is arranged between adjacent vertical plates 201, and movable plates 203 are fixedly arranged on the outer walls of both sides of the impact block 202, and the movable plates 203 are sleeved on the outer sides of the vertical plates 201. A lifting assembly is also arranged between the vertical plates 201 for lifting and quickly releasing the impact block 202. A rubber pad 209 is also fixedly arranged on the upper surface of the impact plate 104, and the rubber pad 209 is located directly below the impact block 202, which can prevent the impact block 202 from directly impacting the impact plate 104 and causing damage to the impact plate 104. When it is necessary to impact the sampling tube downward through the impact plate 104, the impact block 202 can be lifted by the lifting assembly and then quickly released. At this time, the impact force generated by the downward movement of the impact block 202 will act on the upper surface of the impact plate 104, so that the impact force acts on the sampling tube with the help of the impact plate 104, and then the sampling tube is gradually inserted into the soil, which is very convenient to use.

[0027] As an embodiment of the present invention, please refer to Figure 2 and Figure 3The lifting assembly includes a support rod 204 fixedly arranged on the upper surface of the impact block 202, and a shaft roller 205 is fixedly arranged at the end of the support rod 204, and a driving motor 207 is fixedly arranged on the outer wall of the vertical plate 201. The specific structure of the driving motor 207 is not limited. In this embodiment, preferably, the driving motor 207 adopts a servo motor, and a rotating shaft 206 is arranged at the driving end of the driving motor 207. The rotating shaft 206 is rotatably arranged between adjacent vertical plates 201, and the outer wall of the rotating shaft 206 is fixedly provided with equidistantly distributed crescent plates 208 for driving the shaft roller 205 moves up and down, and the driving motor 207 can drive the rotating shaft 206 to rotate, so that the crescent plate 208 outside the rotating shaft 206 rotates together, and the rotating crescent plate 208 can gradually lift the shaft roller 205, and the shaft roller 205 drives the impact block 202 to rise together through the support rod 204. When the crescent plate 208 is separated from the shaft roller 205, the impact block 202 moves down quickly under the action of its own gravity to impact the impact plate 104. In this way, the intermittent impact effect of the impact block 202 on the impact plate 104 can be achieved by repeating the cycle, and the use effect is better.

[0028] As an embodiment of the present invention, please refer to Figure 2 The limiting mechanism includes a hanging plate 301 rotatably arranged on the upper surface of the impact plate 104, and the cross-section of the hanging plate 301 is inverted J-shaped, a hanging groove 302 is opened on the upper surface of the mounting plate 103, and the end of the hanging plate 301 is hung in the hanging groove 302, and grip rods 303 are fixedly arranged on the outer walls on both sides of the hanging plate 301. When it is necessary to limit the position of the impact plate 104, the grip rod 303 can be directly grasped to lift the hanging plate 301 so that its end is hung in the hanging groove 302, so that the impact plate 104 can be quickly limited, and it is very convenient to use.

The outer walls of the lever 409 are fixed with fixed shafts 410, and the ends of the fixed shafts 410 are rotatably connected to the inner walls of the mounting openings 411. The clamping plate 406 and the lever 409 are rotatably connected via the connecting rod 408. The outer wall of the vertical rod 401 is also fixed with a support piece 404, and the moving block 402 is located above the support piece 404. The sampling tube is inserted into the soil through the clamping plates 406 during the insertion process of the sampling tube. In this way, when the sampling tube needs to be pulled out, it can be The lever 409 is directly pressed downward to make the other end of the lever 409 tilt up, and the clamping plate 406 is driven to rotate through the connecting rod 408 until the clamping groove 407 on the clamping plate 406 clamps the outer side of the sampling tube, and after clamping, as the lever 409 further tilts up, the moving block 402 can be driven to slide upward on the outer side of the vertical rod 401, and the clamping force is also increased, so that the sampling tube can be pulled up together, and when the lever 409 is no longer pressed down, under the weight of the moving block 402, the sampling tube can be pulled up together. Under the action of force, the moving block 402 will automatically move downward until it is lifted by the supporting piece 404 on the vertical rod 401, and when the moving block 402 moves downward, the clamping plate 406 will automatically release the clamping of the sampling tube. After the moving block 402 moves downward, the lever 409 returns to its original position, and the lever 409 can be pressed down again. In this way, the sampling tube can be gradually pulled out of the soil. With the help of the lever 409, the sampling tube pulling process can be made more labor-saving and the use effect is better.

[0030] As an embodiment of the present invention, please refer to Figure 4 and Figure 5 A movable shaft 412 is movably provided through the outer wall of the lever 409, and rollers 413 are fixedly provided at both ends of the movable shaft 412.

The push plate 415 is located above the roller 413. When the lever 409 needs to be pushed, the push plate 415 can also be driven to rise and fall by the telescopic cylinder 414. When the push plate 415 contacts the roller 413, the lever 409 can be automatically pressed down, so that the sampling tube can be automatically pulled out, and the use effect is better.

[0031] As an embodiment of the present invention, please refer to Figure 1 , Figure 6 and Figure 7The positioning mechanism includes a fixing rod 501, an outer wall of the base 101 is provided with fixing openings which are equidistantly distributed in an annular shape, and the fixing rod 501 is fixedly arranged in the fixing opening, and a limiting ring 502 is fixedly arranged at the top and bottom ends of the fixing rod 501, and an outer wall of the limiting ring 502 is provided with movable openings which are equidistantly distributed in an annular shape, and a clamping block 503 is movably arranged in the movable opening, and an inclined surface 506 is provided at one end of the clamping block 503 which is located in the limiting ring 502, and a baffle 506 is fixedly arranged at the other end of the clamping block 503 4, and the baffle 504 and the limiting ring 502 are connected by a spring 505, and the sampling tube can pass through the limiting ring 502 and be inserted into the soil. When the sampling tube passes through the limiting ring 502, the sampling tube will first contact the inclined surface 506 on the clamping block 503 and push the clamping block 503 to move around until the sampling tube passes over the clamping block 503. At this time, under the action of the spring 505, the clamping block 503 can play a role in clamping and limiting the sampling tube, so that the sampling tube can be inserted into the soil in a vertical state, and the use effect is better.

[0032] When in use, after the device moves to the position to be taken soil, the position of the base 101 can be adjusted by telescoping the telescopic cylinder 106 so that the base 101 remains horizontal, and then the sampling tube can be placed in the soil taking opening on the base 101, and the sampling tube can be kept vertical under the action of the binding mechanism. At this time, the limit of the impact plate 104 by the limiting mechanism can be released first, and then the impact plate 104 can be made to impact the sampling tube under the action of the impact mechanism, so as to drive the sampling tube to move downward, so that the sampling tube is inserted into the position to be taken soil. After the sampling tube is inserted, other sampling tubes can be spliced ​​with the sampling tube inserted into the soil, and the sampling tube can be impacted again by the impact plate 104 until the sampling tube reaches the appropriate sampling point, effectively realizing the sampling operation of soils of different depths. When the sampling tube needs to be pulled out after the sampling is completed, the sampling tube can be directly pulled out of the soil with the help of the pulling mechanism, effectively realizing the integrated plug-in and pull-out operation of the sampling tube, thereby improving the sampling efficiency and achieving better use effect.
