Description

Technical Field

[0001] The present invention relates to the technical field of on-site surveying devices, and particularly to an on-site surveying device and a surveying method for engineering design. Background Technique

[0002] Geological exploration is to conduct surveys and detections of geology through various means and methods.

[0003] Chinese invention patent CN118168844A discloses a sampling device for geological engineering exploration. By using a vibration sensor and a first pressure sensor to monitor the vertical vibration amplitude and horizontal displacement trend of the sampling drill rod, and then controlling the vibration damping mechanism and the first positioner to regulate the sampling accuracy of the sampling drill rod at a predetermined sampling position.

[0004] The above device samples the soil through the sampling drill rod. However, when the soil is transported upward along the sampling drill rod and moves above the ground, the soil will fly outward under the action of centrifugal force, resulting in the mixing of soils at different depths. Moreover, the above device cannot collect and store the soil transported on the sampling rod in a timely manner. In summary, there is still room for improvement in the above device.

[0005] Therefore, it is necessary to provide an on-site surveying device and a surveying method for engineering design to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an on-site surveying device and a surveying method for engineering design to solve the problem that the existing device samples the soil through the sampling drill rod, but when the soil is transported upward along the sampling drill rod and moves above the ground, the soil will fly outward under the action of centrifugal force, resulting in the mixing of soils at different depths. Moreover, the above device cannot collect and store the soil transported on the sampling rod in a timely manner when in use.

[0007] Based on the above idea, the present invention provides the following technical solution: An on-site surveying device for engineering design, including a base and a drill pipe arranged above the base. A spiral blade is installed on the outer side of the drill pipe. A connecting pipe is fixedly arranged at the top end of the drill pipe. Arc-shaped left and right enclosing plates are respectively arranged on both sides of the top of the base. Limit strips are fixedly arranged on the front and rear sides of the top of the base. When the left and right enclosing plates are mutually attached to the outer side of the spiral blade, the left and right enclosing plates can slide in cooperation with the limit strips;

[0008] A mudguard is elastically mounted on the left side plate. A spiral support plate is fixedly arranged on the outer side of the drill pipe. The bottom end of the support plate is attached to the top end of the spiral blade. A plurality of baffles are connected to the top surface of the support plate through a clamping component. The bottom surface of the mudguard is elastically connected with a push block. Both sides of the bottom end of the push block are arranged as fourth inclined surfaces. A notch matching with the push block is formed on the top surface of the baffle. When two adjacent baffles are separated, the clamping component on the lower baffle is disengaged from the support plate. When the mudguard moves to the baffle disengaged from the support plate and the push block is inserted into the notch, the cooperation between the push block and the notch can drive the baffle to slide relative to the support plate.

[0009] As a further scheme of the present invention: A connection block is arranged at a position close to the top end on the outer side of the connecting pipe. The connecting pipe passes through the connection block and is rotationally matched with the connection block. And lifting plates are detachably connected to both sides of the connection block.

[0010] As a further scheme of the present invention: The clamping component includes a clamping block arranged on the bottom surface of the baffle and elastically matched with the baffle. The clamping block is arranged at a position close to the top end of the baffle. A clamping groove matching with the clamping block is formed on the top surface of the support plate. Both sides of the bottom end of the clamping block are arranged as inclined extrusion parts. In the initial state, the extrusion parts are completely placed in the clamping groove. A limiting rod is arranged above the clamping block. The limiting rod is elastically matched with the baffle. And a groove is formed on the bottom surface of the limiting rod. A top rod is fixedly arranged on the top surface of the clamping block. When the two baffles are separated from each other, the limiting rod can pop out so that the top rod can be aligned with the groove.

[0011] As a further scheme of the present invention: A boss is arranged above the mudguard. The boss is fixed on the outer wall of the left side plate. And a pin is arranged at the boss. A jack matching with the pin is formed on the top surface of the mudguard.

[0012] As a further scheme of the present invention: A positioning rod is elastically connected to the baffle at the notch. A positioning hole matching with the positioning rod is formed on the push block. A vertical rod is arranged below the positioning rod. And the vertical rod is elastically connected with the baffle. A slot matching with the vertical rod is formed on the bottom surface of the positioning rod. In the initial state, the top end of the vertical rod is in the slot.

[0013] As a further scheme of the present invention: A magnetic plate is fixedly embedded on the support plate. A magnetic block matching with the magnetic plate is fixedly embedded on the end face of the bottom end of the vertical rod. The surfaces of the magnetic block and the magnetic plate facing each other have different magnetic poles. When the push block cooperates with the notch and drives the baffle to move upward along the support plate, the baffle can pass through the magnetic plate.

[0014] As a further scheme of the present invention: The baffle is of a spiral structure. And when the baffle rotates one circle, the two ends of the baffle are on the same vertical plane.

[0015] As a further solution of the present invention: A motor is installed below one of the lifting plates, and the motor is used to drive the connecting pipe to rotate.

[0016] As a further solution of the present invention: A plurality of vertically arranged limiting grooves are provided on the inner side surface of the limiting strip. At both ends of the left enclosing plate and the right enclosing plate, convex strips extend outward. Elastic limiting blocks that are slidably matched with the limiting grooves are installed on the outer side surface of the convex strips. On the side of the limiting strip close to the drill pipe and at both sides, inclined pressing surfaces are provided.

[0017] A method of surveying using the above engineering design on-site survey device includes the following steps: Driving the connecting pipe and the drill pipe to move downward and penetrate into the ground through the lifting plate, driving the drill pipe to rotate through the connecting pipe, and using the spiral blades on the outer side of the drill pipe to convey the soil upward; When the left enclosing plate and the right enclosing plate are attached to the outer side of the spiral blades, the mud guard can collect the soil; Through the cooperation of the mud guard and the spiral blades, the left enclosing plate and the right enclosing plate can be driven to move upward, so as to store the collected soil.

[0018] Compared with the prior art, the beneficial effects of the present invention are: When this device is used, the mud guard can drive the soil stored in the inner cavities of the left enclosing plate and the right enclosing plate to move upward along the spiral blades. By providing a plurality of baffles on the support plate, when the mud guard moves upward, it can sequentially call each baffle from top to bottom. At this time, the baffles can block the lower part of the left enclosing plate and the right enclosing plate. When the mud guard moves to the connecting pipe, the mud guard, the baffle, the left enclosing plate, the right enclosing plate, and the connecting pipe form a space for storing soil. Later, by removing the connecting pipe from the drill pipe, multiple groups of soil samples can be sealed. The overall operation is fast and can avoid the mixing of different samples.

DETAILED DESCRIPTION

[0038] like Figures 1 - 10 As shown, an engineering design on-site survey device and survey method include a base 1 and a drill pipe 12 arranged above the base 1, a spiral blade 1201 is fixedly installed on the outer side of the drill pipe 12, and a drill bit is fixedly installed on the bottom end of the drill pipe 12, and a through hole is opened at the center position of the base 1 to facilitate the drill pipe 12 and the spiral blade 1201 on the outer side of the drill pipe 12 to pass through.

[0039] In order to drive the drill pipe 12 to move downward, a connecting pipe 7 is fixedly connected to the top of the drill pipe 12 by screws, and a connecting block 10 is arranged on the outside of the connecting pipe 7 and near the top. The connecting pipe 7 passes through the connecting block 10 and rotates with it, and the two sides of the connecting block 10 are detachably connected with the lifting plate 9. In actual use, the connecting block 10 can be fixed to the lifting plate 9 by bolt connection. A screw rod 6 is arranged at the lifting plate 9, and the screw rod 6 passes through the lifting plate 9 and is threadedly connected with it. Through this structure, the connecting pipe 7 and the drill pipe 12 can be driven to move downward. In addition, a motor is installed under one of the lifting plates 9, and the motor is transmission-connected with the connecting pipe 7. Specifically, the output shaft of the motor passes through the lifting plate 9 and is fixedly sleeved with a gear, and the output shaft of the motor rotates with the lifting plate 9. The outer side of the connecting pipe 7 is fixedly sleeved with a gear ring 8 meshing with the gear, so as to drive the connecting pipe 7 and the drill pipe 12 to rotate. Through this structure, the drill pipe 12 can be drilled into the ground and the soil can be transported to the ground through the spiral blade 1201.

[0040] In order to store the soil conveyed by the spiral blade 1201, the present solution is provided with a left enclosure plate 2 and a right enclosure plate 3 on both sides of the top of the base 1. Both the left enclosure plate 2 and the right enclosure plate 3 are arc-shaped structures. When the left enclosure plate 2 and the right enclosure plate 3 are mutually attached, they can form a complete cylindrical structure, and the left enclosure plate 2 and the right enclosure plate 3 can be attached to the outside of the spiral blade 1201. On the front and rear sides of the top of the base 1, limiting strips 4 are fixedly arranged. When the left enclosure plate 2 and the right enclosure plate 3 are mutually attached and clamped, the left enclosure plate 2 and the right enclosure plate 3 can be in sliding fit with the limiting strips 4;

[0041] Furthermore, a mudguard 202 is elastically installed on the left enclosure plate 2. The mudguard 202 can move along its diameter direction relative to the left enclosure plate 2. Refer to Figures 13 - 15 As shown, the mudguard 202 can be inserted into the spiral blade 1201, and the height of the mudguard 202 is slightly less than the pitch of the spiral blade 1201, that is: when the mudguard 202 is inserted into the spiral blade 1201, the bottom surface of the mudguard 202 can contact the top surface of the spiral blade 1201, while there is only a small distance between the top surface of the mudguard 202 and the bottom surface of the spiral blade 1201. Since the mudguard 202 is restricted by the left enclosure plate 2 and cannot rotate, therefore, as the spiral blade 1201 rotates, it can drive the mudguard 202 to move upward, and then drive the left enclosure plate 2 and the right enclosure plate 3 to move upward relative to the drill pipe 12.

[0042] Refer to Figures 1 - 9 As shown, a spiral support plate 16 is also fixedly arranged on the outside of the drill pipe 12. The bottom end of the support plate 16 is in contact with the top end of the spiral blade 1201, so that the baffle 1601 can slide from the spiral blade 1201 to the support plate 16. The top surface of the support plate 16 is connected with a plurality of baffles 1601 through a clamping component. Adjacent two baffles 1601 are mutually attached. In practical applications, the thickness of the support plate 16 can be greater than or equal to the thickness of the spiral blade 1201, and a chamfer can be arranged at the position near the bottom end of the top surface of the baffle 1601 adjacent to the spiral blade 1201, so as to facilitate the mudguard 202 to move to this baffle 1601. Through the arranged clamping component, the baffle 1601 can be locked on the support plate 16 to prevent the baffle 1601 from sliding relative to the support plate 16. When adjacent two baffles 1601 are separated, the clamping component on the baffle 1601 below is disengaged from the support plate 16, so that this baffle 1601 can move relative to the support plate 16. The baffle 1601 is a spiral structure, and the baffle 1601 only rotates one circle, so that the two ends of the baffle 1601 are on the same vertical plane. The bottom surface of the mudguard 202 is elastically connected with a push block 17. Refer to Figures 14 - 17 As shown, a notch 20 matching with the push block 17 is arranged at the position near the bottom end of the top surface of the baffle 1601. Refer to Figures 2 - 6 、Figure 12 As shown, both sides of the bottom end of the push block 17 are provided with fourth inclined surfaces 1703. When the push block 17 is in the ejected state and inserted into the notch 20, the fourth inclined surface 1703 can contact the side edge of the notch 20. When the left enclosure plate 2 and the right enclosure plate 3 that are mutually attached move upward so that the mudguard 202 moves to the topmost baffle 1601, through the cooperation of the push block 17 and the notch 20, the topmost baffle 1601 can be connected to the mudguard 202, which causes the topmost baffle 1601 not to rotate synchronously with the support plate 16. At this time, when the spiral support plate 16 rotates, the force exerted by the support plate 16 on the baffle 1601 can drive the baffle 1601 and the left enclosure plate 2 and the right enclosure plate 3 outside it to move upward, and the cooperation between the mudguard 202 and the baffle 1601 can prevent the soil inside the left enclosure plate 2 and the right enclosure plate 3 from falling, thus completing the collection of the soil.

[0043] The vertical height from the top surface of the baffle 1601 to the bottom surface of the support plate 16 is equal to the pitch of the spiral blade 1201. The purpose of this setting is that the mudguard 202 can slide between the baffle 1601 and the support plate 16.

[0044] As Figures 3 - 17 shown, the clamping component includes a clamping block 22 provided on the bottom surface of the baffle 1601 and elastically cooperating with the baffle 1601. The clamping block 22 is provided at a position near the top of the baffle 1601, and a clamping groove 1602 cooperating with the clamping block 22 is opened on the top surface of the support plate 16. Refer to Figure 12 shown, both sides of the bottom end of the clamping block 22 are provided with inclined extrusion parts 2201. In the initial state, the extrusion parts 2201 are completely placed in the clamping groove 1602. At this time, the clamping block 22 cooperates with the clamping groove 1602 through the straight edge on its side, which is beneficial to locking the baffle 1601 on the support plate 16.

[0045] Further, a limiting rod 21 is provided above the clamping block 22. The limiting rod 21 elastically cooperates with the baffle 1601, and a groove 2101 is opened on the bottom surface of the limiting rod 21. A top rod 2202 is fixedly provided on the top surface of the clamping block 22. When the two baffles 1601 are mutually attached, the limiting rod 21 is compressed into the baffle 1601, and when the two baffles 1601 are mutually separated, the limiting rod 21 can pop out, so that the top rod 2202 can be aligned with the groove 2101. At this time, the clamping block 22 can move upward, so that the extrusion part 2201 on the clamping block 22 can be aligned with the side edge of the clamping groove 1602, thereby providing conditions for the clamping block 22 to move out of the clamping groove 1602.

[0046] Refer to Figures 1 - 4As shown, a boss 204 is provided above the fender 202. The boss 204 is fixed to the outer wall of the left side panel 2, and a pin is provided at the boss 204. A jack matching with the pin is opened at the top surface of the fender 202 to lock the fender 202 to the left side panel 2;

[0047] During actual use, the screw rod 6 drives the lifting plate 9 and the connecting block 10 to move downward, thereby driving the connecting pipe 7 and the drill pipe 12 to move downward. The spiral blade 1201 can convey the soil to the ground. When the drill pipe 12 moves downward to a corresponding depth, the pin can be pulled upward, so that the fender 202 can bounce toward the direction close to the drill pipe 12 and be inserted into the spiral blade 1201. Since the left side panel 2 and the right side panel 3 are in sliding fit with the limiting strip 4, the left side panel 2 and the right side panel 3 cannot rotate, which causes the fender 202 to only move vertically along with the left side panel 2. The rotation of the spiral blade 1201 can drive the fender 202 to move upward, thereby driving the left side panel 2 and the right side panel 3 to move upward synchronously. The soil located inside the left side panel 2 and the right side panel 3 and on one side of the fender 202 can be pushed by the fender 202 and move upward along the spiral blade 1201;

[0048] When the fender 202 moves from the spiral blade 1201 to above the support plate 16, the fender 202 can move along the upper surface of the baffle 1601. Since the top end of the baffle 1601 is locked to the support plate 16 by the clamping block 22, when the push block 17 is aligned with the notch 20 and inserted into the notch 20, the cooperation between the push block 17 and the notch 20 cannot drive the baffle 1601 below the support plate 16 to move. However, the clamping block 22 on the topmost baffle 1601 is not completely inserted into the card slot 1602. When the fender 202 moves to the topmost baffle 1601 and the push block 17 is inserted into the notch 20 on the topmost baffle 1601, the force between the push block 17 and the notch 20 is sufficient to pull the clamping block 22 on the topmost baffle 1601 out of the card slot 1602, so that the topmost baffle 1601 can move synchronously with the fender 202 relative to the support plate 16. With the continuous rotation of the support plate 16, the force of the support plate 16 on the topmost baffle 1601 can drive it to move upward, thereby driving the fender 202, the left side panel 2 and the right side panel 3 to move upward. When the left side panel 2 and the right side panel 3 move upward to the outside of the connecting pipe 7, the spiral baffle 1601 can contact the outer wall of the connecting pipe 7. At this time, the baffle 1601, the fender 202, the left side panel 2, the right side panel 3 and the connecting pipe 7 enclose a relatively closed storage space, and only the upper part of this storage space is in an open state, and the collected soil is stored in this storage space;

[0049] After the top baffle 1601 moves relative to the support plate 16, the limiting rod 21 at one end of the second baffle 1601 from top to bottom will pop out, so that the ejector rod 2202 can be aligned with the groove 2101, and the clamping block 22 can move upward relative to the baffle 1601. Specifically, refer to Figure 12 As shown, when the clamping block 22 moves upward relative to the baffle 1601, the extrusion part 2201 on the clamping block 22 will be aligned with the side edge of the clamping groove 1602. Subsequently, when the next group of left enclosing plates 2 and right enclosing plates 3 move to this baffle 1601, the clamping block 22 can be pulled out of the clamping groove 1602 through the cooperation of the push block 17 and the notch 20, so that this baffle 1601 can also move relative to the support plate 16. Repeating the above operations can sequentially call each baffle 1601 from top to bottom, so as to cooperate with the mudguard 202, left enclosing plate 2 and right enclosing plate 3 to store the soil. Since multiple groups of left enclosing plates 2 and right enclosing plates 3 are all outside the connecting pipe 7, after the survey is completed, the connecting pipe 7 can be directly disassembled from the drill pipe 12 to seal multiple groups of soil samples.

[0050] In summary, when this device is used, the mudguard 202 can drive the soil stored in the inner cavities of the left enclosing plate 2 and the right enclosing plate 3 to move upward along the spiral blade 1201. By arranging multiple baffles 1601 on the support plate 16, each baffle 1601 can be sequentially called from top to bottom during the upward movement of the mudguard 202. At this time, the baffle 1601 can block the lower part of the left enclosing plate 2 and the right enclosing plate 3. When the mudguard 202 moves to the connecting pipe 7, the mudguard 202, baffle 1601, left enclosing plate 2, right enclosing plate 3 and connecting pipe 7 form a space for storing soil. Later, the connecting pipe 7 can be removed from the drill pipe 12 to seal multiple groups of soil samples. The overall operation is fast and can avoid mixing different samples together.

[0051] A positioning rod 19 is elastically connected to the baffle 1601 at the notch 20, and a positioning hole 1702 matching the positioning rod 19 is provided on the push block 17. Further, a vertical rod 18 is arranged below the positioning rod 19, and the vertical rod 18 is elastically connected to the baffle 1601. A slot matching the vertical rod 18 is provided on the bottom surface of the positioning rod 19. In the initial state, the top end of the vertical rod 18 is in the slot to lock the positioning rod 19. Refer to Figures 10 - 16As shown, a magnetic plate 1603 is fixedly embedded on the top surface of the support plate 16 near the top, and a magnetic block matching the magnetic plate 1603 can be fixedly embedded on the bottom end surface of the vertical rod 18. The magnetic block has different magnetic poles on the side opposite to the magnetic plate 1603. In actual use, when the push block 17 cooperates with the slot 20 and drives the baffle 1601 to move upward along the support plate 16, the baffle 1601 can pass through the magnetic plate 1603, and when the vertical rod 18 moves to the magnetic plate 1603, the suction force between the magnetic plate 1603 and the magnetic block can drive the vertical rod 18 to move downward, thereby separating the vertical rod 18 from the positioning rod 19. At this time, the positioning rod 19 can pop out and be inserted into the positioning hole 1702, so that the push block 17 can be locked with the baffle 1601 to prevent the two from separating.

[0052] like Figures 1 - 2 As shown, brackets 11 are fixedly provided on both sides of the top of the base 1, and the brackets 11 are arranged in an L shape. The two ends of the screw rod 6 are rotatably matched with the brackets 11 and the base 1 respectively (the two ends of the screw rod 6 are arranged as a bare rod structure), and the bottom end of the screw rod 6 passes through the base 1, and a driving motor is installed under the base 1, and the output end of the driving motor is transmission-connected with one end of the screw rod 6 passing through the base 1, so as to drive the screw rod 6 to rotate forward and reverse.

[0053] A support frame is fixedly arranged outside the limit strip 4 and near the top. The support frame is U-shaped and fixedly connected to the bracket 11. A roller is installed at the bottom end of the base 1.

[0054] The outer side of the connecting tube 7 is provided with a pressing ring 23, and the pressing ring 23 is fixedly arranged on the bottom surface of the connecting block 10. Through this structure, the connecting block 10 can more stably drive the connecting tube 7 to move downward, and the connecting tube 7 can cooperate with the connecting block 10 through a tapered roller bearing.

[0055] The inner side of the limit strip 4 is provided with a plurality of vertical limit grooves 401, and the left and right enclosure plates 2 and 3 are both extended outward at both ends to form convex strips, and the outer side of the convex strip is provided with a mounting groove, and a limit block 13 is slidably arranged in the mounting groove, and a limit spring is fixedly arranged between the limit block 13 and the inner end surface of the mounting groove, and the ... Figures 1 - 6 As shown, the limiting strip 4 is provided with inclined extrusion surfaces 402 on one side close to the drill pipe 12 and at both sides. In actual use, when the left enclosure 2 and the right enclosure 3 are pushed to fit the outside of the spiral blade 1201, the convex strip can move to the inside of the limiting strip 4, and the limiting block 13 can move to the limiting groove 401 through the extrusion surface 402. The cooperation between the limiting block 13 and the limiting groove 401 can prevent the left enclosure 2 or the right enclosure 3 from rotating.

[0056] Furthermore, combined with Figures 1 - 7As shown, a second inclined surface 1301 is provided at one end of the limiting block 13 close to the limiting strip 4 and located at the top surface. A plurality of protrusions 15 are fixedly arranged on the surface of the limiting groove 401 opposite to the limiting block 13. Through this structure, the left enclosure panel 2 or the right enclosure panel 3 can only move upward unidirectionally relative to the limiting strip 4, which is beneficial to maintaining the stability of the left enclosure panel 2 and the right enclosure panel 3 outside the connecting pipe 7.

[0057] Referring again to Figures 1 - 6 As shown, in order to clamp the left enclosure panel 2 and the right enclosure panel 3, a plug rod 205 is fixedly arranged at the rib of the left enclosure panel 2, and strip-shaped grooves are formed on the top surface and the bottom surface of the plug rod 205. A convex block 14 is slidably arranged in the strip-shaped groove. One end of the convex block 14 away from the plug rod 205 is provided with a first inclined surface 1401, and a spring is fixedly arranged between the inner end surface of the strip-shaped groove and the convex block 14. A through groove matching with the plug rod 205 is formed at the rib of the right enclosure panel 3. When the left enclosure panel 2 and the right enclosure panel 3 are attached, the plug rod 205 can pass through the through groove. When the convex block 14 passes over the rib of the right enclosure panel 3, the convex block 14 can pop out, thereby locking the left enclosure panel 2 and the right enclosure panel 3.

[0060] Combined with Figures 9 - 14As shown, one side of the bottom surface of the push block 17 is provided with a third inclined surface 1701. Through this structure, during the process of the fender 202 being inserted into the spiral blade 1201, the third inclined surface 1701 will contact the side of the spiral blade 1201, thereby avoiding interference between the push block 17 and the spiral blade 1201.

[0061] A rectangular groove that slidably cooperates with the push block 17 is formed in the fender 202, and a spring is fixedly arranged between the inner end surface of the rectangular groove and the push block 17.

[0062] Combined with Figures 3 - 12 As shown, a first guiding groove that slidably cooperates with the positioning rod 19 is formed in the inner side wall of the notch 20. A second spring is fixedly arranged between the inner end surface of the first guiding groove and the positioning rod 19. A second guiding groove communicating with the first guiding groove is further formed in the baffle 1601. The second guiding groove is used for installing the vertical rod 18. A "return" - shaped retaining strip is fixedly arranged at the bottom end inside the second guiding groove. An extrusion spring is fixedly arranged between the retaining strip and the vertical rod 18. The top end surface of the vertical rod 18 can be inclined, which is beneficial to the installation of the positioning rod 19.

[0063] A cross - shaped groove for installing the clamping block 22 and the limiting rod 21 is formed in the baffle 1601. The clamping block 22 and the limiting rod 21 are respectively distributed vertically and horizontally in the cross - shaped groove and slidably cooperate with the cross - shaped groove. A reset spring is fixedly arranged between the inner end surface of the cross - shaped groove and the limiting rod 21. A spring seat is fixedly arranged on the inner wall of the cross - shaped groove, and a tension spring is fixedly arranged between the spring seat and the clamping block 22, so that the clamping block 22 is elastically matched with the baffle 1601.
