Description

Technical Field

[0001] The invention relates to the technical field of water conservancy survey equipment, in particular to a water conservancy survey construction equipment that is easy to use. Background Art

[0002] In water conservancy projects, the survey stage is one of the important links in project planning and design. The main task of water conservancy survey is to collect and analyze basic data such as geology, hydrology, and geomorphology in the project area in order to provide a scientific basis for subsequent design and construction. Especially in water conservancy projects such as reservoirs, dams, and channels, geological conditions have a direct impact on the safety and stability of the project. Therefore, in order to accurately grasp the underground structure characteristics of the construction site, drilling and sampling of soil and rocks become necessary means.

[0003] Chinese patent (Announcement No.: CN117211689A), the solution specifically includes a support plate, the surface of the support plate is provided with a groove, a lower probe plate is installed in the groove, the inner surface of the groove is hinged with two connecting blocks, both sides of the lower probe plate are slidably connected to the connecting blocks, and a locking mechanism for fixing the position of the lower probe plate is provided in the connecting block, and also includes: a fixing component for fixing the support plate is installed at one end of the support plate away from the lower probe plate, a shell fixedly installed at the lower end of the lower probe plate, a drilling component for drilling rock walls for sampling is installed on the surface of the shell, a steel cable installed on one side of the shell for enhancing drilling stability, a positioning component for positioning the steel cable is installed on the upper surface of the shell, and a pushing component slidably installed in the support plate. The problem that the existing drilling sampling device is not stable enough when drilling cliffs is solved.

[0004] The above-mentioned patent completes the drilling and sampling process of soil and rock through a drilling assembly. The existing drilling process usually analyzes the drilled samples to determine the composition of the soil and rock. Therefore, during the drilling process, since the formation composition of the drilling position is still unclear, the drilling speed is difficult to determine. Among them, a slow feed speed of the drill rod will reduce the drilling efficiency, and if the feed speed of the drill rod is too fast, the drill rod may break when encountering a hard formation, which may increase equipment loss and maintenance frequency. Therefore, it is difficult for existing survey and construction equipment to adaptively adjust the drilling speed of unknown soil or rock sampling points.

[0005] At the same time, during the process of drilling into the rock, the drill rod can be cooled by natural water, coolant or mud to extend the service life of the drill rod. However, when drilling and sampling the soil layer, the use of cooling medium will affect parameters such as the moisture content of the soil layer, which may lead to deviations in subsequent analysis results. Therefore, it is not appropriate to use cooling medium when drilling in the soil layer. When hard objects such as stones are mixed in the soil layer, the continuous drilling process may cause the drill rod to overheat and affect its service life. Therefore, an easy-to-use water conservancy survey and construction device is proposed. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 10 The present invention provides a technical solution: a water conservancy survey and construction device that is easy to use, including a steel frame 1 and a base 2 for supporting a drill rod 18, the base 2 is provided with a drilling groove 201 for the drill rod 18 to penetrate, a centering shaft 37 is fixedly connected to the steel frame 1, the base 2 is rotated on the steel frame 1 with the centering shaft 37 as the center, and a self-drilling structure is provided on the base 2 for driving the drill rod 18 to intermittently drill into soil layers and rocks; The self-drilling structure comprises a drilling seat 5 arranged on a base 2, a connecting frame 17 for supporting a drill rod 18 is arranged on the drilling seat 5, a chuck for clamping and fixing the drill rod 18 is arranged on the connecting frame 17 and a fixed axis is rotated, and a fixed displacement component for driving the drilling seat 5 to intermittently move in a vertical direction is arranged on the base 2; The connecting frame 17 is provided with a drill pressing assembly for driving the drill rod 18 to rotate horizontally when the horizontal height of the drill seat 5 remains unchanged, and the base 2 is provided with a groove guide column 20 for preventing the drill seat 5 from rotating. The groove guide column 20 is provided with a shock assembly for knocking the drill rod 18 when the height of the drill seat 5 is raised; The steel frame 1 is provided with a positioning assembly for driving the base 2 to rotate horizontally after the drill rod 18 has completed a single drilling operation to change the subsequent drilling position of the drill rod 18; The fixed and shifting assembly includes a hollow screw rod 3 sleeved on a centering shaft 37, the hollow screw rod 3 is fixedly rotated on a base 2, the hollow screw rod 3 is threadedly connected with an internal threaded tube 4, the internal threaded tube 4 is fixedly rotated on a drilling seat 5, a positioning plate 7 is provided on the drilling seat 5, and a receiving groove for sliding connection of the positioning plate 7 is opened on the drilling seat 5; A pressure spring 8 is provided in the receiving groove, and the two ends of the pressure spring 8 are fixedly connected to the positioning plate 7 and the drilling seat 5 respectively; The internal threaded barrel 4 is provided with a positioning groove 6 corresponding to the positioning plate 7 , and the drill seat 5 is provided with a press lock component for driving the positioning plate 7 to disengage from the positioning groove 6 .

[0022] like Figure 1 and Figure 2 As shown, when drilling into soil or rock, the steel frame 1 is fixedly supported at the drilling point, and the drill seat 5 and the connecting frame 17 and the drill rod 18 thereon are driven downward by the fixed displacement assembly until the drill rod 18 contacts the ground. Taking soil drilling as an example, when the drill rod 18 is in tight contact with the soil, the drill seat 5 stops moving downward, and under the action of the drill pressure assembly, the drill rod 18 can rotate freely on the connecting frame 17, and while the drill rod 18 rotates, the connecting frame 17 is subjected to a downward force, and the drill rod 18 can exert a certain pressing force on the soil.

[0023] At the same time, under the action of the pressing force, the drill rod 18 has a tendency to move downward. At the same time, since the drill rod 18 rotates freely in the horizontal direction, the drill rod 18 can drill downward. As the drill rod 18 gradually drills downward in the process, the pressing force applied by the drill rod 18 to the soil layer gradually decreases, and after the pressing force disappears, the drill seat 5 can continue to move downward for a certain distance, but the drill rod 18 cannot continue to move downward due to the resistance of the soil layer. Therefore, the downward movement of the drill seat 5 can drive the drill rod 18 to apply a certain pressing force to the soil layer again, and then under the action of the drill pressure assembly, the drill rod 18 continues to rotate horizontally and drills to a certain depth again. Through the reciprocating rotation process of the drill rod 18 and the process of applying a pressing force to the soil layer, the intermittent rotation process of the soil layer is realized.

[0024] It should be noted that the drill rod 18 can only move downward when it can exert a pressing force on the soil layer. Therefore, when there are harder strata or rocks in the soil layer, the drill rod 18 can adaptively adjust the drilling speed according to the hardness of the strata or rocks under the pressing action, that is, when encountering hard strata, the drilling speed can be slowed down. Therefore, when drilling into soil layers whose stratum composition is still unclear, there will be no broken rod failure due to excessive drilling speed, thereby ensuring the smooth progress of the drilling process.

[0025] At the same time, when the drill rod 18 is lifted upward after the drilling process is completed, the drill rod 18 can be continuously provided with a horizontal knocking force under the drive of the shock assembly. The drill rod 18 and the drill bit provided at the end of the drill rod 18 may be subject to greater resistance due to factors such as drilling friction, soil adhesion or consolidation. By lifting and knocking the drill rod 18, the soil around the drill rod 18 can be loosened, reducing the risk of jamming of the drill rod 18 and ensuring that the drill bit and the drill rod 18 can be lifted out more smoothly.

[0026] At the same time, during the sampling of the soil layer, the sample may be tightly adhered to the inner tube of the drill rod 18. By applying a knocking force to the drill rod 18, the sample can be loosened, making it easier to remove the sample from the drill rod 18. In addition, during the lifting process of the drill rod 18, the soil may adhere to the drill bit or the outer wall of the drill rod 18, thereby increasing the lifting resistance. Therefore, by applying a knocking force, the soil attached to it can be fallen off, thereby reducing the resistance of the drill rod 18.

[0027] Furthermore, after a single drilling is completed and the drill seat 5 and the drill rod 18 are restored to their initial heights, the base 2 can be driven to rotate a certain angle in the horizontal direction under the premise that the position of the steel frame 1 remains unchanged, thereby changing the orientation of the drill rod 18 and collecting soil in different directions at the same drilling point without moving or repositioning the steel frame 1, thereby improving the construction efficiency during multiple drillings.

[0028] In one of the more preferred embodiments, the compression lock assembly includes a limit plate 10 disposed on the drill seat 5, and a vertical through groove is provided on the drill seat 5 for the limit plate 10 to be slidably connected in the vertical direction, and the limit plate 10 is fixedly connected to the connecting frame 17; The positioning plate 7 is fixedly connected to a limiting pin 9 on one side facing the limiting plate 10 , and the limiting plate 10 is provided with a V-shaped groove 11 for the limiting pin 9 to be slidably connected.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, the hollow screw 3 is driven to rotate in the horizontal direction by a motor fixed on the base 2, and in the initial state, the positioning plate 7 is in the positioning groove 6, and the positioning plate 7 is arranged in the drill seat 5, and the drill seat 5 is restricted by the groove guide column 20 and cannot rotate horizontally. Therefore, when the hollow screw 3 rotates horizontally, the internal threaded tube 4 is restricted by the positioning plate 7 and cannot rotate with the internal threaded tube 4, and then the rotation process of the hollow screw 3 can drive the drill seat 5 to move in the vertical direction through the internal threaded tube 4, thereby changing the horizontal height of the connecting frame 17 and the drill rod 18.

[0030] At the same time, when the drill rod 18 is in contact with the soil layer and cannot move downward, the internal threaded tube 4 and the drill seat 5 can continue to move downward under the drive of the hollow screw 3, so that the relative position between the drill seat 5 and the limit plate 10 changes, and then drives the limit pin 9 to slide on the V-shaped groove 11, and drives the horizontal position of the limit pin 9 and the positioning plate 7 to change, so that the positioning plate 7 is disengaged from the positioning groove 6. At this time, the internal threaded tube 4 is no longer restricted by the positioning plate 7, and then when the hollow screw 3 rotates subsequently, the internal threaded tube 4 can rotate synchronously with the hollow screw 3, and the horizontal height of the drill seat 5 no longer changes.

[0031] In addition, the internal threaded tube 4 can drive the drill pressure assembly to operate when rotating, thereby causing the chuck that fixes and clamps the drill rod 18 to rotate horizontally on the connecting frame 17. When the limit pin 9 slides on the V-shaped groove 11, the horizontal position change of the positioning plate 7 will drive the pressure spring 8 to undergo compression deformation, and the deformation of the pressure spring 8 will drive the limit plate 10 and the connecting frame 17 thereon and the drill rod 18 to move downward through the limit pin 9 and the V-shaped groove 11, thereby enabling the drill rod 18 to exert a certain pressing force on the soil layer.

[0032] Among them, with the horizontal rotation of the drill rod 18, the drill rod 18 can drill to a certain depth under the pressing force. At this time, with the drilling of the drill rod 18, the limit plate 10, the driven bevel gear 16 and the drill rod 18 move downward relative to the drill seat 5 under the action of the elastic potential energy of the pressure spring 8, so that the pressure spring 8 can gradually restore its deformation until the positioning plate 7 enters the positioning groove 6 again. The internal threaded tube 4 will be restricted by the positioning plate 7 and cannot rotate with the hollow screw 3 and will not drive the drilling assembly to operate.

[0033] At this time, the rotation process of the hollow screw rod 3 still drives the internal threaded tube 4 and the drilling seat 5 to move downward, so that the relative displacement between the limit plate 10 and the drilling seat 5 occurs again, and then the positioning plate 7 is disengaged from the positioning groove 6 again, and the pressure spring 8 is compressed and deformed again, and the pressure drill assembly is operated again, so that the drill rod 18 can apply a certain pressing force to the soil layer when it rotates horizontally, and the continuous relative displacement between the active bevel gear 15 and the limit plate 10 is realized, thereby realizing the drilling process of the soil layer.

[0034] It should be noted that the drilling process of the drill rod 18 is intermittent. Only when the drill rod 18 can exert a pressing force on the soil layer can it be driven to drill to a certain depth. When the positioning plate 7 has not separated from the positioning groove 6, the drill rod 18 will not rotate in the horizontal direction. Therefore, through the intermittent drilling method of the drill rod 18, when a large amount of heat is generated by the friction of the soil or rock layer and the cutting of the drill bit, especially when encountering harder formations, the continuous heat generation may cause the drill bit temperature to rise sharply. Intermittent drilling allows the drill rod 18 and the drill bit to have the opportunity to dissipate heat at each pause, thereby reducing the heat accumulated during continuous drilling, thereby reducing the thermal fatigue effect of the material, and thereby increasing the service life of the drill bit and the drill rod 18.

[0035] On the basis of the fixed displacement assembly embodiment, the pressure drill assembly comprises a hollow spline column 12 which is sleeved on the hollow screw rod 3 and fixed coaxially with the internal threaded tube 4, a spline tube 13 is slidably sleeved on the outer ring of the hollow spline column 12, a yield spring 14 is fixedly connected to the spline tube 13, and one end of the yield spring 14 away from the spline tube 13 is fixedly connected to the internal threaded tube 4; The spline cylinder 13 is fixedly sleeved with a driving bevel gear 15, which is meshedly connected with a driven bevel gear 16. The driven bevel gear 16 rotates on a fixed axis on a connecting frame 17, and the driven bevel gear 16 is coaxially fixed with the chuck.

[0036] like Figure 3-Figure 6 As shown, when the positioning plate 7 is disengaged from the positioning groove 6, the internal threaded tube 4 is no longer restricted by the positioning plate 7. At this time, the hollow screw 3 drives the internal threaded tube 4 to rotate horizontally synchronously, and the internal threaded tube 4 can drive the spline tube 13 and the active bevel gear 15 to rotate synchronously through the hollow spline column 12 coaxially arranged thereon, and then drive the driven bevel gear 16 to rotate on the connecting frame 17 through the active bevel gear 15, so as to achieve the purpose of rotating the drill rod 18 in the horizontal direction.

[0037] At the same time, due to the relative displacement between the limit plate 10 and the drill seat 5, there will be a displacement difference between the connecting frame 17 and the drill seat 5, and the relative position between the internal threaded tube 4 and the drill seat 5 will not change. Therefore, multiple sets of yield springs 14 are arranged between the spline tube 13 and the internal threaded tube 4. When there is a relative displacement between the limit plate 10 and the drill seat 5, the drill rod 18 can still be driven to rotate in the horizontal direction by the rotation of the internal threaded tube 4, thereby realizing the drilling process of pressing the spring 8.

[0038] On the basis of the embodiment of the pressure drill assembly, the shock assembly includes a positioning frame 26 fixedly connected to the drill seat 5, and a circular groove for the groove guide column 20 to pass through is opened on the positioning frame 26, and a positioning disk 25 is fixedly rotated on the positioning frame 26, and the positioning disk 25 is slidably sleeved on the groove guide column 20; The drill seat 5 is slidably sleeved on the groove guide column 20, and both ends of the groove guide column 20 are fixedly rotated on the base 2; The co-positioning frame 26 is provided with a rectangular rod 30 that can move freely in the horizontal direction. The end of the rectangular rod 30 that faces the drill rod 18 is provided with a ball stud 32 that is fixedly connected.

[0039] The isotropic frame 26 is fixedly connected with a rectangular frame 28, and the rectangular frame 28 is provided with a slot for the rectangular rod 30 to slide horizontally. The lower surface of the isotropic plate 25 is fixedly connected with a lower extension column 27, and the side of the rectangular rod 30 facing the lower extension column 27 is provided with a lateral column 31 that is in contact with the lower extension column 27. A return spring 29 is disposed in the groove body 1, and two ends of the return spring 29 are fixedly connected to the rectangular rod 30 and the rectangular frame 28 respectively.

[0040] like Figure 3 and Figure 7 As shown, the groove guide column 20 slides through the drill seat 5, so the groove guide column 20 can prevent the drill seat 5 from rotating horizontally following the hollow screw 3. At the same time, the existence of the drill seat 5 can provide a certain supporting force when the groove guide column 20 rotates, thereby ensuring the stability of the groove guide column 20 when it rotates. When the groove guide column 20 rotates horizontally, it can drive the isotropic disk 25 slidably mounted thereon to rotate synchronously, thereby driving the lower extension column 27 fixedly set on the isotropic disk 25 to rotate synchronously.

[0041] At the same time, when the lower extension column 27 rotates horizontally, it can contact with the lateral column 31 and push the lateral column 31 to move horizontally a certain distance, thereby driving the rectangular rod 30 fixed to the lateral column 31 and the ball head column 32 set at the end of the rectangular rod 30 to move in the horizontal direction. At the same time, when the lower extension column 27 is separated from the lateral column 31, under the action of the return spring 29, the rectangular rod 30 can return to its initial position, thereby realizing the horizontal reciprocating motion process of the rectangular rod 30 on the rectangular frame 28.

[0042] Among them, the ball head column 32 can contact the drill rod 18 when it is in the terminal position of horizontal movement, thereby knocking the drill rod 18 and applying a horizontal knocking force to the drill rod 18, and then by lifting and knocking the drill rod 18, the soil around the drill rod 18 can be loosened, reducing the risk of jamming of the drill rod 18, and ensuring that the drill bit and the drill rod 18 can be lifted out more smoothly.

[0043] Furthermore, the shock assembly further includes a central gear 21 coaxially fixed with the hollow screw 3, the central gear 21 is meshedly connected with a side gear 22, the side gear 22 is fixedly rotated on the base 2, a plurality of groups of inward grooves arranged in a circular array are provided on the side gear 22, a ratchet 23 is provided in the inward groove, and the ratchet 23 is fixedly rotated on the side gear 22; The pawl 23 is meshedly connected with a one-way ratchet 24 , and the one-way ratchet 24 is coaxially fixed with the groove guide column 20 .

[0044] like Figure 1 , Figure 8 and Fig. 9 As shown, the rotation process of the hollow screw 3 can drive the center gear 21 to rotate synchronously in the horizontal direction. The center gear 21 is meshed and connected with the side gear 22. Therefore, the hollow screw 3 and the side gear 22 rotate synchronously. At the same time, when the side gear 22 rotates, it can drive the one-way ratchet 24 to rotate according to its different direction of rotation. Among them, when the rotation of the hollow screw 3 drives the drill seat 5 to move downward, the side gear 22 will not drive the one-way ratchet 24 to rotate. When the hollow screw 3 drives the drill seat 5 to move upward to lift the drill rod 18, the pawl 23 arranged on the side gear 22 can engage with the one-way ratchet 24 when it rotates, thereby driving the one-way ratchet 24 and the groove guide column 20 coaxial with the one-way ratchet 24 to rotate in the horizontal direction, thereby driving the rectangular rod 30 to reciprocate in the horizontal direction and causing the ball head column 32 to knock the drill rod 18.

[0045] It should be noted that the rotation of the groove guide column 20 is limited by setting the pawl 23 and the one-way ratchet 24, so that the groove guide column 20 can only knock the drill rod 18 during the lifting process of the drill seat 5 and the drill rod 18, so as to avoid the knocking process from interfering with the drilling process of the drill rod 18, thereby ensuring the smooth progress of the drilling process.

[0046] Based on the embodiment of the shock assembly, the positioning assembly includes a T-shaped seat 38 arranged on the base 2, and the base 2 is provided with a second slot for the T-shaped seat 38 to slide through in the vertical direction, and the T-shaped seat 38 is provided with a rack 35 that moves freely thereon, and the rack 35 is meshedly connected with a fixed gear 36, and the fixed gear 36 is coaxially fixed with a centering shaft 37; One end of the limiting plate 10 facing the T-shaped seat 38 is fixedly connected with a top plate 19 .

[0047] A guide pin 39 is fixedly connected to one side of the rack 35 facing the T-shaped seat 38, and a guide groove 40 for the guide pin 39 to slide and connect is provided on the T-shaped seat 38. The guide groove 40 includes a straight groove portion 401 and an arc groove portion 402 which are integrally formed and connected end to end. A swing rod 33 is coaxially fixed on the one-way ratchet 24 , and a push rod 34 that is in contact with the swing rod 33 is fixedly connected to the rack 35 .

[0048] like Figure 1 , Figure 4 , Figure 8 , Fig. 9 and Fig.10As shown, when the rotation of the hollow screw 3 can drive the drill seat 5 and the drill rod 18 to rise, the one-way ratchet 24 can drive the rocker arm 33 fixed thereon to rotate horizontally synchronously, wherein, as the drill seat 5 and the limit plate 10 rise, the top plate 19 fixed at the top of the limit plate 10 can be driven to contact the T-shaped seat 38 and push the T-shaped seat 38 to move upward.

[0049] Among them, the rack 35 is meshedly connected with the fixed gear 36. When the rack 35 moves upward following the T-shaped seat 38, the top plate 19 can support the T-shaped seat 38, and the push rod 34 set on the rack 35 can be roughly at the same height as the rocker arm 33, that is, the rocker arm 33 can contact the push rod 34 when following the rotation of the one-way ratchet 24.

[0050] At the same time, the horizontal rotation of the push rod 34 can drive the rack 35 to slide on the straight groove portion 401 through the push rod 34, wherein the fixed gear 36 is fixedly set on the steel frame 1 through the centering shaft 37, so the fixed gear 36 will not rotate, and the rack 35 is engaged with the fixed gear 36 and moves on the T-shaped seat 38. Therefore, the rack 35 can drive the base 2 to rotate a certain angle with the fixed gear 36 as the center through the T-shaped seat 38, thereby changing the direction of the drill rod 18, so that it can automatically change the direction of the drill rod 18 during multiple continuous drillings without moving or repositioning the steel frame 1.

[0051] It should be noted that, in actual use, a tension spring is arranged between the base 2 and the rack 35, so that the two ends of the tension spring are respectively hung on the base 2 and the rack 35, and when the rack 35 moves under the rotation of the push rod 34, it can be restored to its initial position under the action of the tension spring, wherein, in the process of the rack 35 returning to its initial position, the guide pin 39 arranged thereon moves to the end of the straight groove portion 401, and since the groove depth of the arc groove portion 402 is greater than the groove depth of the straight groove portion 401, the guide pin 39 is a spring pin with a certain deformation amount, and then the guide pin 39 is in the arc groove portion 402 at this time, and moves to the initial position along the opening direction of the arc groove portion 402, so that the guide pin 39 is in the straight groove portion 401 again, and when the rocker arm 33 pushes the push rod 34 next time, the guide pin 39 can still slide on the straight groove portion 401.

[0052] Furthermore, when the guide pin 39 slides on the arc groove portion 402, the rack 35 can disengage from the fixed gear 36, so the two are no longer in a meshing state. When the rack 35 returns to its initial position under the action of the tension spring, it will not drive the base 2 to rotate due to its own displacement process. At the same time, in actual use, a rubber pad that increases the friction resistance can be provided at the joint between the base 2 and the steel frame 1 to ensure the stability of the base 2 during the drilling process of the drill rod 18.

[0053] Among them, if the push rod 34 on the T-shaped seat 38 is located under the rocker arm 33 during the rising process and cannot move upward, at this time, since the limit plate 10 can have a certain relative displacement with the drilling seat 5, when the drilling seat 5 is lifted at this time, the horizontal heights of the top plate 19, the limit plate 10 and the T-shaped seat 38 remain unchanged, but as the drilling seat 5 is lifted, the one-way ratchet 24 and the rocker arm 33 continue to rotate until the rocker arm 33 no longer hinders the rising process of the push rod 34, and the push rod 34 moves to the same height as the rocker arm 33. Therefore, when the T-shaped seat 38 rises, no matter what position its rocker arm 33 is in, it will not hinder the rising process of the push rod 34, and in the subsequent rotation process of the rocker arm 33, the rack 35 can still be driven to move through the push rod 34 to ensure the smooth rotation of the base 2 on the steel frame 1.
