Description

Technical Field

[0001] This application relates to the technical field of engineering surveying, and in particular to a surveying device. Background Technology

[0002] Engineering survey refers to the surveying, exploration, and testing of topography, geology, and hydrology to meet the needs of planning, design, construction, operation, and comprehensive management of engineering projects. First, the feasibility of the building is determined, then a general geological survey is conducted, and finally, a detailed survey is conducted to understand the soil and rock conditions of each stratum, determine the bearing capacity of the foundation, and then adopt appropriate construction methods.

[0003] During geological exploration, it is usually necessary to sample the soil in the area being explored. In order to improve the accuracy of the exploration results, multiple samplings are often taken at different locations within the area. When the exploration equipment in the relevant technology takes a sample at one location using a sampling tube, the soil sample in the sampling tube needs to be removed and taken at another location using the same sampling tube, which is inefficient. Summary of the Invention

[0004] In order to improve the efficiency of exploration equipment when performing multiple soil samplings, this application provides an exploration device.

[0005] This application provides a surveying device, which adopts the following technical solution:

[0006] An exploration device includes a mobile frame on which a soil sample transport device and a soil sample collection device are mounted. The soil sample transport device includes a transport plate slidably mounted on the mobile frame and a first drive mechanism for driving the transport plate to move horizontally. A plurality of sample containers are mounted on the transport plate, and a clamping mechanism is positioned above the transport plate. The soil sample collection device includes a rotating cylinder slidably mounted below the soil sample transport device and a second drive mechanism for driving the rotating cylinder to rotate. The clamping mechanism transports the sample containers into the rotating cylinder. An abutment edge is provided on the inner wall of the rotating cylinder for abutting against the sample containers. When the second drive mechanism drives the sample containers to rotate, the clamping mechanism drives the sample containers to move vertically. After soil is collected, the sample containers can be detachably connected to the transport plate. A discharge assembly is provided on one side of the clamping mechanism, and a soil sample storage box is positioned below the discharge assembly. The discharge assembly moves the sample containers into the soil sample storage box.

[0007] By adopting the above technical solution, several sample containers are set on the transport plate. The clamping mechanism can transport the sample containers into the rotating cylinder. When the second drive mechanism drives the rotating cylinder to rotate, the clamping mechanism drives the sample containers to move vertically downward, thereby indirectly driving the rotating cylinder to move vertically downward, so that the rotating cylinder can drill and collect soil samples, and the soil samples enter the sample containers. The operator can slide the rotating cylinder out of the soil layer and take out the sample containers from the rotating cylinder. The first drive mechanism drives the transport plate to move, so that another sample container is transported above the rotating cylinder, waiting for the next sampling. The sample container containing the soil sample is transported to the underside of the unloading assembly and moved into the soil sample storage box by the unloading assembly. During this process, the soil sample is left in the sample container, and the remaining sample containers are used for the next sampling. Continuous sampling is carried out without removing the soil sample from the sample container, which improves the efficiency of the exploration equipment when performing multiple soil samplings.

[0008] Optionally, a slide rail is fixed on the mobile frame, the transport plate is slidably disposed on the slide rail, and a plurality of receiving cylinders for accommodating the sample barrels are spaced apart on the transport plate. A support component for supporting the sample barrels is disposed inside the receiving cylinders; the clamping mechanism can drive the support component to move.

[0009] By adopting the above technical solution, the sample bucket is supported in the receiving cylinder by the support component, which reduces the probability of the sample bucket tipping over during transportation on the transport plate; the clamping mechanism drives the support component to move, and when the support component moves, it no longer supports the sample bucket, so that the sample bucket moves into the rotating cylinder under the drive of the clamping mechanism and is clamped and abutted between the edge and the clamping mechanism.

[0010] Optionally, the pressing mechanism includes a pressing push rod and a first driving source for driving the pressing push rod to move vertically; a plurality of receiving grooves are formed on the inner side wall of the receiving cylinder; the support assembly includes a support block slidably disposed in the receiving groove and a first resetting member disposed between the support block and the receiving groove; the support block is provided with a guide surface for abutting against the sample cylinder; when the sample cylinder is pressed down, the support block can retract into the receiving groove through the guide surface.

[0011] By adopting the above technical solution, when the first transport mechanism transports the sample bucket to the area directly below the push rod, the push rod presses down to make the sample bucket move vertically downward. As the sample bucket moves downward, it comes into contact with the guide surface, driving the support block to move so that the support block moves completely into the receiving groove. The push rod continues to drive the sample bucket to move vertically downward into the rotating cylinder.

[0012] Optionally, the first driving mechanism includes a transmission rack disposed at the bottom of the transport plate, and two transmission gears meshing with the transmission rack, the transmission rack being disposed along the length direction of the transport plate; the two transmission gears are spaced apart, and each transmission gear is connected to a second driving source for driving its own rotation.

[0013] By adopting the above technical solution, when the second drive source drives the transmission gear to rotate, the transmission gear meshes with the rack and thus drives the transport plate to move in the horizontal direction; there are two transmission gears, so that when the transmission rack on the transport plate is no longer in contact with the transmission gear on one side, the transmission gear on the other side can continue to mesh with the gear to drive the transport plate to move.

[0014] Optionally, the mobile frame is provided with two guide plates located below the transport plate, and the rotating cylinder is slidably disposed between the two guide plates; an end ring is rotatably connected to the top of the rotating cylinder, and the end ring is slidably connected between the two guide plates; a guide block is provided on the end ring, and the guide plate is provided with a guide groove for the guide block to slide in the vertical direction.

[0015] By adopting the above technical solution, the two guide plates fix the position of the rotating cylinder, making it easy for the transport plate to transport the sample bucket to the top of the rotating cylinder. After the sample bucket is pressed into the rotating cylinder by the pressing mechanism, the pressing rod continues to press down, driving the rotating cylinder to move vertically downward, so that the rotating cylinder is inserted into the soil for sampling.

[0016] Optionally, the second driving mechanism includes a first gear disposed on one side of the end ring and a second gear sleeved on the outer wall of the rotating cylinder, wherein the first gear and the second gear mesh with each other, and a third driving source for driving the second gear to rotate is provided on the end ring.

[0017] By adopting the above technical solution, when the rotating cylinder moves downward and is inserted into the soil, the third drive source drives the first gear to rotate, which in turn drives the second gear meshing with the first gear to rotate, thereby indirectly driving the rotating cylinder to rotate; the rotating cylinder rotates while being inserted into the soil, which facilitates sampling by the rotating cylinder.

[0018] Optionally, a connecting plate is provided at one end of the pressing push rod, and two abutment strips are slidably arranged inside the connecting plate. A driving assembly for driving the abutment strips to slide out of the connecting plate is provided on the connecting plate. The top of the sample barrel is closed, and a connecting groove for accommodating the connecting plate is opened at one closed end of the sampling barrel. An abutment groove for accommodating the abutment strips is opened on the inner side wall of the connecting groove, and the connecting plate cannot rotate within the connecting groove.

[0019] By adopting the above technical solution, after the pressing push rod moves to abut against the sample bucket, the connecting plate is engaged in the connecting groove, and the driving component drives the abutment strip to slide into the abutment groove, thereby realizing the connection between the pressing push rod and the sample bucket; after the soil sample is taken from the sample bucket, the pressing push rod moves in the vertical direction to remove the sample bucket from the rotating cylinder.

[0020] Optionally, the drive assembly includes a drive gear rotatably disposed within the connecting plate and a fourth drive source for driving the drive gear to rotate; drive racks are provided on the two abutment bars, and the drive racks are located on both sides of the drive gear and mesh with the drive gear.

[0021] By adopting the above technical solution, when the connecting plate is engaged in the connecting groove, and the fourth drive source drives the drive gear to rotate, the two abutting bars that mesh with the drive rack and drive gear move in opposite directions, and slide out of the connecting plate to engage with the abutting groove.

[0022] Optionally, the support block is provided with a magnet at one end near the rotating cylinder for attracting and fixing with the sample container, and the unloading assembly includes an unloading push rod and a fifth drive source for driving the unloading push rod to slide in the vertical direction.

[0023] By adopting the above technical solution, a magnet is set at one end of the support block near the rotating cylinder. When the push rod moves vertically upward, the sample bucket containing the soil sample is taken out from the rotating cylinder and transported to the receiving cylinder. When the sample bucket comes into contact with the support block, it is attracted by the magnet on the support block. At this time, the fourth drive source drives the two abutment bars to move relative to each other and return to the connecting plate, thereby disconnecting the connection between the push rod and the sample bucket. The sample bucket is fixed on the support block, and the push rod continues to move vertically upward to return to the initial position. When the transport plate transports another sample bucket to the top of the rotating cylinder, the sample bucket containing the soil sample moves with the transport plate to the bottom of the unloading assembly. The fifth drive source drives the unloading push rod to move vertically downward, pushing the sample bucket containing the soil sample into the soil sample storage box.

[0024] Optionally, one end of the rotating cylinder is provided with several serrations, which are spaced apart along the axis of the rotating cylinder; a cap is detachably connected to the side wall of the sample container.

[0025] By adopting the above technical solution, the rotating cylinder has several serrations, which makes it easier to insert into the soil during the soil sampling process, thus facilitating sampling; the side wall of the sample container is detachably connected to a cap, which makes it easy for the testing personnel to take out the soil sample from the cap.

[0026] In summary, this application includes at least one of the following beneficial effects:

[0027] 1. When the rotating drum is used for sampling, the soil sample is stored in the sample bucket, and the sample bucket is removed from the rotating drum after the soil sample is collected. When multiple sampling is required, another sample bucket is transported to the rotating drum. There is no need to remove the soil sample from the sample bucket, which improves the efficiency of multiple sampling and reduces the possibility that the soil structure is damaged before the soil sample is tested.

[0028] 2. The clamping mechanism can transport the sample bucket into the rotating cylinder. As the rotating cylinder rotates under the drive of the second drive mechanism, the clamping mechanism continues to drive the sample bucket to move vertically, thereby indirectly driving the rotating cylinder to move vertically downward, thus realizing the sampling function of the rotating cylinder.

[0029] 3. A connecting plate is provided on the push rod, and a connecting groove is provided on the sample bucket. An abutment strip is slidably provided in the connecting plate. An abutment groove for accommodating the abutment strip is opened on the inner side wall of the connecting groove, so that the push rod can be detachably connected to the sample bucket. After the sample bucket collects soil samples, the push rod can remove the sample bucket from the rotating cylinder. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0040] This application discloses an exploration device, which is described in an embodiment. Figure 1 and Figure 2 An exploration device includes a mobile frame 1 and a soil sample collection device 3 and a soil sample transport device 2 mounted on the mobile frame 1.

[0041] Reference Figure 1 and Figure 2 The mobile frame 1 is equipped with a slide rail frame 5, which includes two opposing slide rails 51 and support legs 52 fixed below the slide rails 51. Two support legs 52 are provided below each slide rail 51 and are welded to the mobile frame 1. The soil sample transport device 2 includes a transport plate 21 slidably disposed above the soil sample collection device 3, a first drive mechanism 24 for driving the transport plate 21 to move horizontally, and a clamping mechanism 11 disposed above the transport plate 21. The transport plate 21 slides between the two slide rails 51, and the slide rails 51 have grooves 511 along their length for the sides of the transport plate 21 to slide.

[0042] Reference Figure 3 and Figure 4A plurality of sample containers 4 are disposed on a transport plate 21, and a plurality of receiving cylinders 22 are fixedly fixed on the transport plate 21 at intervals. The sample containers 4 are disposed inside the receiving cylinders 22 with their openings facing downwards. A support assembly 23 for supporting the sample containers 4 is disposed inside the receiving cylinders 22. In this embodiment, there are four receiving cylinders 22 and four sample containers 4. An mounting plate 221 for mounting the support assembly 23 is integrally formed on the outer circumferential side wall of the receiving cylinder 22. A plurality of receiving grooves 2211 are formed on the receiving cylinder 22, and the receiving grooves 2211 extend into the mounting plate 221. The support assembly 23 includes a support block 231 slidably disposed in the mounting plate 221, and a first reset member 232 disposed between the support block 231 and the inner wall of the receiving groove 2211. A guide surface is provided at the end of the support block 231 near the pressing mechanism 11, and the guide surface gradually slopes downwards away from the pressing mechanism 11. In this embodiment, there are four support blocks 231, and adjacent support blocks 231 are disposed at 90° intervals along the axis of the receiving cylinder 22.

[0043] Reference Figure 3 The first driving mechanism 24 includes a transmission rack 241 fixed to the end of the transport plate 21 away from the pressing mechanism 11, and two transmission gears 242 meshing with the transmission rack 241. The two transmission gears 242 are located on the same side of the transmission rack 241 and are spaced apart. Both transmission gears 242 are connected to a second driving source 243, and the second driving source 243 is fixed to the support leg 52. In this embodiment, the second driving source 243 is specifically configured as a motor, and the drive shaft of the motor is fixedly connected to the transmission gears 242 to drive the transmission gears 242 to rotate, thereby indirectly driving the transport plate 21 to move in the vertical direction.

[0044] Reference Figure 3 and Figure 4 The pressing mechanism 11 includes a pressing push rod 111 and a first driving source 112 that drives the pressing push rod 111 to move vertically. The first driving source 112 is fixed on the moving frame 1. In this embodiment, the first driving source 112 is specifically set as a hydraulic cylinder. When the transport plate 21 transports the sample barrel 4 to directly below the pressing mechanism 11, the hydraulic cylinder drives the pressing push rod 111 to move vertically downward, so that the sample barrel 4 also moves downward. Under the action of the guide surface and the sample barrel 4, the support block 231 slides to be completely located in the receiving groove 2211, and the sample barrel 4 can pass through the receiving cylinder 22 and move away from the first driving source 112.

[0045] Reference Figure 5 and Figure 6The soil sampling device 3 includes a sampling drill pipe slidably disposed below the soil sample transport device 2 (not shown in the figure). Two guide plates 6 are fixed on the moving frame 1 below the transport plate 21, and the sampling drill pipe is slidably disposed between the two guide plates 6. The sampling drill pipe includes an end ring 31 and a rotating cylinder 32 rotatably connected to the end ring 31. An abutment edge 321 for abutting against the sample container 4 is fixed at the end of the rotating cylinder 32 away from the end ring 31. The abutment edge 321 is disposed around the inner circumferential side wall of the rotating cylinder 32. An abutment rotating ring that abuts against the abutment edge 321 is rotatably connected to the bottom of the sample container 4. When the push rod 111 is pressed down to drive the sample container 4 to move into the sampling drill pipe, the sample container 4 is further driven to move downward, so that the abutment rotating ring of the sample container 4 abuts against the abutment edge 321.

[0046] Reference Figure 1 and Figure 5 In this embodiment, the two guide plates 6 are specifically symmetrically arranged arc-shaped plates. Guide blocks 312 are welded to both sides of the end ring 31, and guide grooves 61 are provided on the two guide plates 6 for the guide blocks 312 to slide in the vertical direction. A connecting ring 323 is integrally formed at one end of the rotating cylinder 32 near the end ring 31. A rotating groove 311 is provided on the end face of the end ring 31 for the end ring 31 to move. The connecting ring 323 rotates in the rotating groove 311, thereby realizing the rotational connection between the end ring 31 and the rotating cylinder 32.

[0047] Reference Figure 5 and Figure 6 The soil sampling device 3 includes a second drive mechanism 33 for driving the rotating cylinder 32 to rotate. The second drive mechanism 33 includes a first gear 331 rotatably disposed on one side of the end ring 31 and a second gear 332 sleeved and fixed on the outer wall of the rotating cylinder 32. The second gear 332 is located at the end of the rotating cylinder 32 near the connecting ring 323 and meshes with the first gear 331. The end of the rotating cylinder 32 away from the connecting ring 323 is integrally formed with a plurality of serrations 322. In this embodiment, a plurality of serrations 322 are arranged around the axis of the rotating cylinder 32 to facilitate the insertion of the rotating cylinder 32 into the soil, facilitate cutting, and reduce energy consumption. A third drive source 333 for driving the first gear 331 to rotate is fixed on the end ring 31. In this embodiment, the third drive source 333 is specifically configured as a motor, and the drive shaft of the motor is fixedly connected to the first gear 331.

[0048] When the contact ring of sample bucket 4 abuts against the contact edge 321 inside the rotating cylinder 32, during the process of the third drive source 333 driving the rotating cylinder 32 to rotate, the downward push rod 111 continues to drive the sample bucket 4 to move downward, so that the sample bucket 4 indirectly drives the rotating cylinder 32 to move vertically downward, thereby realizing the sampling function of the sampling drill pipe. During the sampling process of the sampling drill pipe, the soil sample enters the sample bucket 4.

[0049] Reference Figure 7 and Figure 8A connecting plate 7 is provided at the end of the push rod 111 away from the first drive source 112. The connecting plate 7 is specifically rectangular. An installation cavity 71 is provided inside the connecting plate 7. Two abutment strips 72 are slidably arranged in the installation cavity 71. A drive assembly 73 is provided on the connecting plate 7 to drive the two abutment strips 72 to slide out of the connecting plate 7. A connecting groove 41 for accommodating the connecting plate 7 is opened on the end face of the closed end of the sample barrel 4. An abutment groove 411 for the abutment strips 72 to engage is opened on the inner side wall of the connecting groove 41. The drive assembly 73 includes a drive gear 731 rotatably arranged in the installation cavity 71 and a fourth drive source 732 fixedly connected to the first drive source 112. The fourth drive source 732 is specifically a motor, and in this embodiment, the drive shaft of the fourth drive source 732 is the push rod 111. Two drive racks 733 that mesh with the drive gear 731 are fixed at opposite ends of the two abutting bars 72. The pressing push rod 111 passes through the connecting plate 7 and is rotatably connected to the connecting plate 7. The drive gear 731 is fixed on the pressing push rod 111.

[0050] Reference Figure 7 When the connecting plate 7 abuts against the connecting groove 41 on the sample container 4, the drive gear 731 rotates, driving the two abutment bars 72 to slide out of the connecting plate 7 and engage in the abutment groove 411, thus achieving the connection between the pressing push rod 111 and the sample container 4. When the sample container 4 is filled with soil sample, the pressing push rod 111 moves upward, removing the sample container 4 containing soil sample from the sampling tube.

[0051] Reference Figure 5 A second reset member 62 is provided inside the guide groove 61, and the second reset member 62 is vertically fixed between the inner side wall of the guide groove 61 and the guide block 312. When the push rod 111 moves upward to remove the sample bucket 4 containing the soil sample from the sampling drill pipe, the end ring 31 moves vertically upward under the drive of the second reset member 62, driving the rotating cylinder 32 to move out of the soil and return to its initial position. In this embodiment, both the first reset member 232 and the second reset member 62 are springs.

[0052] Reference Figure 3 and Figure 4 A magnet 233 is provided at one end of the support block 231 near the sampling drill pipe. When the push rod 111 moves upward, causing the sample bucket 4 to return to the receiving cylinder 22, the support block 231 has already slid out of the receiving groove 2211 under the action of the first reset member 232. The sample bucket 4 abuts against the support block 231, and the magnet 233 on the support block 231 attracts the iron sample bucket 4. The push rod 111 continues to move upward, disengaging from the sample bucket 4. The first drive mechanism 24 drives the transport plate 21 to move another sample bucket 4 directly below the clamping mechanism 11. The sample bucket 4 containing the soil sample then moves away from the clamping mechanism 11 with the transport plate 21.

[0053] Reference Figure 3A discharge assembly 8 is provided on one side of the clamping mechanism 11, and a soil sample storage box 9 is fixed below the discharge assembly 8. The soil sample storage box 9 has a feed inlet. The discharge assembly 8 includes a discharge push rod 81 and a fifth drive source 82 fixed on the movable frame 1. The fifth drive source 82 is used to drive the discharge push rod 81 to move in the vertical direction, and the discharge push rod 81 corresponds to the feed inlet.

[0054] Once the sample container 4 containing soil samples is transported directly below the unloading assembly 8, the fifth drive source 82 drives the unloading push rod 81 downwards, pushing the sample container 4 into the soil sample storage box 9. A lever 91 is rotatably mounted inside the soil sample storage box 9, connected to a drive component 92 for its own rotation. When the sample container 4 falls from the feed pipe into the soil sample storage box 9, the drive component 92 drives the lever 91 to rotate, pushing the sample container 4 containing soil samples away from the feed inlet, facilitating the entry of another sample container 4 into the soil sample storage box 9.

[0055] Reference Figure 8 A sampling port 43 is provided on the side wall of the sample container 4. A cap 42 is detachably connected to the sampling port 43. A connecting edge 431 is integrally formed on the inner side wall of the sampling port 43. A snap-fit ​​strip 421 is fixed on both sides of the cap 42. A snap-fit ​​groove 4311 is provided on the connecting edge 431 for snap-fit ​​strip 421 to snap-fit, so as to realize the detachable connection of the cap 42 to the sample container 4, which makes it easier for the testing personnel to take out the soil sample in the sample container 4 more completely.

[0056] The implementation principle of the exploration equipment in this application embodiment is as follows: When the mobile frame 1 moves to the sampling area, the second drive source 243 is activated to drive the transport plate 21 to move, so that a sample bucket 4 moves to the coaxial position of the sampling drill pipe. Then, the first drive source 112 drives the downward push rod 111 to move vertically downward. After the connecting plate 7 on the downward push rod 111 abuts against the connecting groove 41 on the upper end face of the sample bucket 4, the fourth drive source 732 drives the two abutment strips 72 located in the mounting cavity 71 to pass through the connecting plate 7 and insert into the card. Within the groove 4311, the connection between the pressing rod 111 and the sample container 4 is achieved. Subsequently, the first driving source 112 continues to drive the pressing rod 111 to move vertically downward. As the sample container 4 slides out of the receiving cylinder 22, the abutting ring at the lower end of the sample container 4 abuts against the support block 231, causing the support block 231 to slide into the receiving groove 2211. The sample container 4 loses its support and, driven by the pressing rod 111, passes through the end ring 31 and moves into the rotating cylinder 32, where it abuts against the abutting edge 321 inside the rotating cylinder 32.

[0057] When the sample container 4 moves away from the support block 231, the support block 231 moves towards each other under the action of the first reset member 232, returning to its original position. The first drive source 112 continues to drive the downward push rod 111 to transport vertically downwards. At the same time, the third drive source 333 drives the rotating cylinder 32 to rotate. The rotating cylinder 32 passes through the moving frame 1 and enters the soil layer for sampling. The soil sample enters the sample container 4 along the rotating cylinder 32. When the sampling drill pipe completes sampling, the third drive source 333 stops, and the first drive source 112 drives the downward push rod 111 to move upwards, removing the sample container 4 containing the soil sample from the sampling drill pipe. The end ring 31 moves vertically upwards under the action of the second reset member 62, driving the rotating cylinder 32 back onto the moving frame 1.

[0058] When the sample container 4 moves upward and abuts against the support block 231 again, the magnet 233 on the support block 231 attracts the sample container 4. The fourth drive source 732 drives the two abutment bars 72 to slide into the mounting cavity 71, so that the sample container 4 is disconnected from the pressing push rod 111. The first drive source 112 drives the pressing push rod 111 back to the initial position. The third drive source 333 drives the transport plate 21 to move, transporting the other sample container 4 to directly below the clamping mechanism 11, and then moves the sample container 4 containing the soil sample to directly below the unloading push rod 81. The fifth drive source 82 drives the unloading push rod 81 to move downward, pushing the sample container 4 containing the soil sample into the soil sample storage box 9.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
