Description

Technical Field

[0001] The invention relates to the technical field of geological survey and drilling, and in particular to a hydrogeological engineering survey device. Background Art

[0002] Geological survey belongs to the field of geological engineering. It takes natural science and earth science as its theoretical basis, and takes geological survey, mineral resource survey and exploration, geological structure and geological background of major projects as its main objects. It uses geology, geophysics and geochemistry technology, mathematical geological methods, remote sensing technology, testing technology, computer technology, etc. as means to provide services for national economic construction. The purpose of geotechnical survey in geological survey is to provide engineering geological basis for the foundation design and construction of the proposed building in the construction drawing stage, and to propose plans for the utilization, treatment and transformation of the site foundation soil according to the engineering characteristics of the proposed building and the engineering geological conditions of the foundation soil, and to conduct technical and economic analysis and demonstration. The general specific tasks are as follows: 1) Identify the stratigraphic structure, rock and soil type, burial conditions, distribution patterns and physical and mechanical properties of each rock and soil layer within the scope of project influence, and evaluate its engineering characteristics. Identify the thickness of the cover layer in the shallow buried area of ​​the bedrock and the thickness and degree of fragmentation of the bedrock weathering layer; 2) Identify the type, burial conditions and characteristics of groundwater in the proposed site, and evaluate the corrosiveness of groundwater to building materials; 3) Based on the engineering geological conditions of each section of the site, propose a reasonable and economical foundation plan and provide corresponding design parameters. Provide optional pile foundation bearing layers and related pile foundation design parameters.

[0003] Drilling is often used in hydrogeological surveys. Drilling refers to a method of using a drill rig to drill a rod in the stratum to identify and divide the subsurface strata and to take samples along the depth of the hole. However, the existing drilling equipment for hydrogeological surveys is complex in structure and has poor performance.

[0004] The query of the disclosed prior art "CN119021590A, a broken formation drilling equipment for geological drilling" records that "a support frame is installed on the upper surface of the base, a lifting seat is slidably installed on the inner wall of the support frame, and a lifting assembly is installed between the support frame and the lifting seat, an inner seat is provided on the inner wall of the lifting seat, and a drilling assembly is installed on the side wall of the inner seat; the drilling assembly includes a driving motor, a rotating shaft installed at the driving motor, a drill rod installed at one end of the rotating shaft, and a reducing assembly installed between the drill rod and the drill bit; the present invention arranges a lifting assembly, a drilling assembly and a reducing assembly, and the lifting assembly enables the drill rod to be lifted and displaced stably, thereby avoiding drilling interruptions or repeated operations caused by unstable lifting and lowering, and improving the overall drilling efficiency; keeping the driving groove closed to prevent soil from entering and affecting the reducing function, thereby ensuring the reliability and stability of the reducing operation, reducing damage to components such as hydraulic rods due to impurity intrusion, and reducing the maintenance frequency."

[0005] However, the geological drilling equipment of the prior art still has the following disadvantages: First, the geological drilling equipment of the prior art is usually large in structure and heavy in weight. It adopts the traditional non-movable support structure and can only be hoisted and moved by hoisting equipment. When operating at outdoor hydrogeological survey and calibration points, it is time-consuming and labor-intensive, and the use effect is not good. Second, the drill rod structure of the geological drilling equipment of the prior art adopts the traditional main shaft plus spiral blade design, and the structure is relatively simple. In the complex drilling environment of geological survey and calibration point operation, the drill rod is very easy to be entangled by plant roots or waste plastics in the soil, which seriously affects the drilling speed of the drill rod, thereby delaying the progress of geological drilling operations. Third, the geological drilling equipment of the prior art mainly relies on the drill bit for drilling. Over a long period of time, the wear of the drill bit is particularly serious. Therefore, the staff needs to perform maintenance operations on the drill bit to ensure the reasonable and efficient working strength and service life of the drill bit. However, the traditional drill rod and drill bit are both integrated fixed structures, and the overall disassembly and assembly are time-consuming and labor-intensive, which seriously affects the maintenance efficiency of the drill bit.

[0021] 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.

Moreover, the possible terms such as "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the possible statements "including one" and other defined elements do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0023] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "provided with" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] Example: Figures 1 to 11 As shown: A hydrogeological engineering survey device includes a support mechanism 1, a drilling mechanism 2 and a crushing mechanism 3. The support mechanism 1 includes a support frame 4 and a moving member 5. The support frame 4 is horizontally distributed, specifically, as Figure 1 As shown: the support frame 4 includes a bottom plate 41, side wing plates 42 and a top plate 43; the bottom plate 41 is horizontally distributed left and right, and a through hole 44 is provided in the center; it is used for the drill rod 22 and the drill bit 23 to perform drilling operations. The side wing plates 42 are vertically distributed and fixed to the bottom plate 41 by welding; in order to enhance the stability of the support, reinforcing ribs are also provided between the bottom plate 41 and the side wing plates 42. The top plate 43 is parallel to the bottom plate 41 and is arranged at the top of the side wing plates 42; reinforcing ribs are also provided between the two. Figure 2 As shown: a push handle 45 is also provided on one side of the side wing plate 42. The purpose of providing the push handle 45 is to facilitate the staff to push it, to move and adjust the position over a short distance, and to improve the maneuverability of the survey device.

[0025] Reference Figure 2 The structure shown: In a preferred embodiment, the moving member 5 is used to drive the support frame 4 to move; specifically, the moving member 5 includes a moving wheel 51, a connecting arm 52 and an electric telescopic rod 53. The moving wheel 51 is connected and fixed to the connecting arm 52 through a bracket, and one end of the connecting arm 52 is hinged to the bottom plate 41. One end of the electric telescopic rod 53 is hinged to the bottom plate 41, and the other end is hinged to the connecting arm 52; and a clamping position 54 is provided on one side of the bottom plate 41; the clamping position 54 is a groove structure, and the connecting arm 52 and the electric telescopic rod 53 are both in the clamping position 54, and the groove forms a limit for the deflection movement of the connecting arm 52, and the connecting arm 52 is ensured to be vertical in the fixed state. When the support frame 4 is in a fixed state, that is, in a working state, the electric telescopic rod 53 is fully retracted, and the moving wheel 51 is fully retracted into the clamping position 54; at this time, the bottom plate 41 forms the bottom support of the support frame 4. A start-stop button 55 is set on the push handle 45, and the start-stop button 55 is electrically connected to the electric telescopic rod 53. In this embodiment, a backup battery can be provided in the bottom plate 41, or the bottom plate 41 can be connected to an external power source through an external cable to realize electric drive.

[0026] Specific working principle: the staff can realize one-button lifting control without bending over to operate manually. The thrust of the electric telescopic rod 53 is large enough. Through the control of the start-stop button 55, the electric telescopic rod 53 gradually extends until the connecting arm 52 is in a vertical position. At this time, the moving wheel 51 contacts the ground and can be moved conveniently. The cooperation of the moving wheel 51 and the electric telescopic rod 53 is further set to form a lifting structure of the "landing gear", which is convenient for movement and position fixing, and further improves the convenience and efficiency of geological survey calibration point operations.

[0027] like Figure 2 As shown: In this embodiment, the drilling mechanism 2 includes a fixed plate 21, a drill rod 22, and a drill bit 23. Among them, the fixed plate 21 is horizontally distributed and movably arranged on one side of the support frame 4 up and down, specifically, the fixed plate 21 is movably arranged on the side wing plate 42. A hydraulic cylinder 24 is also provided between the fixed plate 21 and the top plate 43; the pressure of the hydraulic cylinder 24 is large enough to provide sufficient driving force for drilling. A guide rod 46 is also provided between the top plate 43 and the bottom plate 41, and such an arrangement provides a guiding support function. The guide rod 46 passes through one side of the fixed plate 21, and the two are kept in sliding connection. With such an arrangement, a certain vertical guiding force is provided by the guide rod 46, and the guide rods 46 can be two parallel arrangements. The drill rod 22 is vertically distributed and rotatably arranged on the fixed plate 21, and the rotation is completed by the drilling drive 6. Specifically, the top end of the drill rod 22 is connected to the fixed plate 21 by a keyway to achieve relative rotation but non-relative movement. Among them, in a preferred embodiment, as Figure 5 As shown in the figure, the drilling drive 6 comprises a drilling motor 61, a driving wheel 62, a driven wheel 63 and a belt 64. The drilling motor 61 is fixedly mounted on the fixing plate 21 through a bracket, the driving wheel 62 is sleeved on the output shaft of the drilling motor 61, the driven wheel 63 is sleeved on the drill rod 22, and the driving wheel 62 and the driven wheel 63 are connected by a belt 64.

[0028] Specific working principle: When the drill bit 23 starts drilling the geological survey calibration point, the drilling motor 61 is started, and the drilling motor 61 will synchronously drive the driving wheel 62 to rotate at high speed. Under the transmission effect of the belt 64, the driving wheel 62 will drive the driven wheel 63 and the drill rod 22 to rotate at high speed as a whole. Next, the staff starts the hydraulic cylinder 24, which can drive the drill bit 23 and the drill rod 22 as a whole to complete the geological drilling operation at the preset depth.

[0029] like Figure 3 and Figure 8-Figure 10As shown: In this embodiment, the drill bit 23 is connected to the drill rod 22 through the connecting structure 7 to achieve quick disassembly and quick assembly. Specifically, the connecting structure 7 includes two connecting columns 71 distributed symmetrically around the center; one of the connecting columns 71 is connected to the drill rod 22, and the other connecting column 71 is connected to the drill bit 23; specifically, it can be fixed by welding. The cross section of the connecting column 71 is an L-shaped structure. In the installed state, the two connecting columns 71 with L-shaped cross sections form a connecting structure 7 with a rectangular cross section. The connecting column 71 is provided with an installation cavity 72 with an overall V-shaped structure, and one side of the installation cavity 72 is provided with an installation hole 73 that communicates with the outside world; wherein the installation hole 73 is located at one outer end of the V-shape, and the outer end of the moving rod 77 is located at the tip of the V-shape. Correspondingly, an openable cover door can be set here to prevent the hole from entering the soil during soil drilling operations. In order to increase safety, the cover door and the connecting column 71 can be connected by a lock body. A limit plate 74 and a locking block 75 of an arc structure are also provided at the mounting hole 73, wherein the limit plate 74 is fixedly arranged on the side wall of the mounting cavity 72. The locking block 75 is a semicircular structure, and a concentrically distributed limit groove 76 is provided on one side, and the limit plate 74 can slide along the limit groove 76. The two locking blocks 75 of the two connecting columns 71 are combined into a circle in the locked state. The locking block 75 is also connected to a moving rod 77, and the two are integrally formed; the moving rod 77 is tilted. The purpose of setting the moving rod 77 is to achieve free unlocking. A support shaft 78 is also provided on the side of the mounting cavity 72 away from the mounting hole 73, and a tension spring 79 is installed on the support shaft 78, and one end of the tension spring 79 is connected to the moving rod 77, specifically, the tension spring 79 is installed on the end of the moving rod 77 away from the locking block 75. And in the initial state (that is, in the locked state), the tension spring 79 naturally extends, and a part of the locking block 75 extends out of the hole to form a block for the adjacent connecting column 71. In a preferred embodiment, a guide groove 711 is provided on the shorter side of the connecting column 71L, and a guide plate 712 is provided on the longer side of the connecting column 71L. The guide plate 712 of the connecting column 71 is matched and installed with the guide groove 711 of another connecting column 71. Such a configuration facilitates position correspondence and enables quick alignment and installation. The shape of the guide plate 712 can be any of a triangle, a rectangle, and a square.

[0030] Specific working principle: In the initial state, the tension spring 79 stretches naturally, a part of the locking block 75 extends out of the hole, and the limit plate 74 is located at one end of the limit groove 76. Among them, the elastic force of the tension spring 79 is large enough; refer to Figure 8The structure in the state shown. When the two connecting columns 71 approach each other, first ensure that the guide block corresponds to the position of the guide groove 711 of the adjacent connecting column 71. Then the staff only needs to push lightly, and the guide blocks and guide grooves 711 of the two connecting columns 71 gradually approach each other. During this process, the facing sides of the connecting columns 71 will squeeze the vertical plane of the locking block 75. The locking block 75 specifically rotates along the limit plate 74 until the vertical plane of the locking block 75 is flush with the facing vertical plane of the connecting column 71. At this time, the two semicircular locking blocks 75 are combined into a circular structure, the outer end of the moving rod 77 moves outward, and the tension spring 79 has deformation and energy storage; refer to the specific Fig. 9 The structure in the state shown is only in a moment. The connecting column 71 continues to move until the guide blocks of the two connecting columns 71 are matched and installed in the guide grooves 711. At this time, the two locking blocks 75 lose their obstruction and will quickly reset under the energy release of the tension spring 79. The protruding part of the locking block 75 will form an obstruction to the side wall of the mounting hole 73 of the adjacent connecting column 71. In this way, a stable connection between the two connecting columns 71 can be achieved. In this state, due to the travel limit cooperation between the limit groove 76 and the limit plate 74, the connection between the two is particularly stable; refer to Fig.10 At the same time, when the two connecting columns 71 are connected, even if the drill bit 23 is in the drilling operation state, the drill rod 22 is subjected to the downward force of the hydraulic cylinder 24, so that the adjacent connecting columns 71 will not be loosened.

[0031] The unlocking action of the two connecting columns 71 is specifically: when the drill bit 23 needs to be disassembled for maintenance, the staff only needs to open the cover door, and then pull one end of the moving rod 77 outward, at which time the tension spring 79 deforms and stores energy; the moving rod 77 will drive the locking block 75 to deflect until the vertical plane of the locking block 75 is flush with the vertical plane facing the connecting column 71, and the staff can manually separate the drill bit 23. The present invention specifically designs the drill rod 22 and the drill bit 23 structure, and coats the wear-resistant superhard coating on the drill teeth 25. While ensuring that the drill bit 23 has sufficient strength for drilling operations, the split connection between the drill bit 23 and the drill rod 22 is realized by a quick disassembly and quick assembly method. This method not only ensures the normal use of the drill bit 23 and the convenience and stability in the connected state, but also can be disassembled by one-key operation during maintenance operations, saving time and effort, avoiding the problem of overall disassembly and removal of a large number of bolts required for the maintenance of the traditional drill bit 23, greatly improving the efficiency of the maintenance of the drill bit 23, and the structural design is reasonable.

[0032] like Figure 3As shown: In this embodiment, the drill bit 23 is also provided with a plurality of evenly distributed drill teeth 25, and each group of drill teeth 25 on the outer wall of the drill bit 23 is distributed in an S-shaped manner in the vertical direction, and the tooth thickness of each group of drill teeth 25 distributed from bottom to top tends to gradually decrease; in specific practical applications, the difference is designed to be 1mm. The purpose of such a setting is to enhance the drilling effect of the drill bit 23. Figure 2 As shown: In this embodiment, the crushing mechanism 3 includes a triggering member 8 and a crushing member 9. Figure 8 As shown: the trigger member 8 includes a base plate 81, a sleeve 82, a sleeve column 83, a trigger rod 84 and a trigger switch 85. The base plate 81 is horizontally distributed and fixed to the bottom end of the hydraulic cylinder 24 by bolts. The sleeve 82 is vertically distributed and arranged below the base plate 81, and the sleeve column 83 extends upward and is distributed and arranged on the fixed plate 21, and is sleeved with the sleeve 82, and a spring 86 is arranged between the two; specifically, the spring 86 is arranged in the sleeve 82, one end of which is connected and fixed to the inner wall of the sleeve 82, and the other end is connected and fixed to the sleeve column 83, and the elastic force of the spring 86 is kept large enough, and when the drill bit 23 is drilling at a normal preset speed, there is still a gap of 10-20mm between the bottom end of the trigger rod 84 and the trigger switch 85. The base plate 81 is parallel to the fixed plate 21, and both are slidably mounted on the guide rod 46. The trigger rod 84 extends downward and is distributed and arranged on the base plate 81, and the two can be connected by threads, that is, the initialization distance between the bottom end of the trigger rod 84 and the trigger switch 85 is adjustable. The trigger switch 85 is arranged on the fixed plate 21, and the two correspond vertically; in actual operation, the trigger switch 85 is the start-stop switch of the drive motor 92. The purpose of the adjustable trigger rod 84 is to reduce the speed and trigger the timing of starting the drive motor 92 when the drill bit 23 is blocked. For example, when the distance between the end of the trigger rod 84 and the trigger switch 85 is large, that is, the drill bit 23 is blocked and the difference in speed reduction is large, the trigger rod 84 will trigger the start trigger switch 85 and then start the crushing part 9 to crush the obstacles; this state is suitable for geological survey scenes with deeper drilling and more complex drilling. When the distance between the end of the trigger rod 84 and the trigger switch 85 is small, that is, the drill bit 23 is blocked less and the difference in speed reduction is small, the trigger rod 84 moves down a small distance, which will trigger the start trigger switch 85 and then start the crushing part 9 to crush the obstacles; this state is suitable for geological survey scenes with shallower drilling and simpler drilling.

[0033] like Figure 6 and Figure 7Structure shown: In this embodiment, the crushing element 9 is configured to complete the cutting and crushing of obstacles around the drilling in the geological survey when the trigger switch 85 is triggered and started. In a preferred embodiment, the crushing element 9 includes a central shaft 91, a driving motor 92 and a central wheel 93. A vertically distributed cavity 94 is provided in the drill rod 22, and the central shaft 91 is rotatably arranged in the cavity 94, and a bearing is also arranged between the cavity 94 and the side wall; a good rotation effect is maintained. The driving motor 92 is fixedly installed in the cavity 94 through the motor and is connected to the central shaft 91; the driving motor 92 adopts a micro servo control motor and is electrically connected to the trigger switch 85. The central wheels 93 are evenly distributed up and down. Each central wheel 93 corresponds to a set of cutting knives, so that obstacles wrapped around the drill rod 22 can be crushed while the drill rod 22 rotates.

[0034] like Figure 7 As shown in the figure: In a preferred embodiment, the crushing member 9 also includes a rack plate 95, a blocking plate 96 and a main cutter 97. A cutout 98 corresponding to the height position of the center wheel 93 is provided on one side of the drill rod 22, and the cutout 98 communicates with the cavity 94 of the center shaft 91. The blocking plate 96 is adapted to be installed at the cutout 98. The inner side of the blocking plate 96 is connected to the rack plate 95, and the main cutter 97 is provided on the outer side; the blocking plate 96 is fixed to the rack plate 95 and the main cutter 97 by welding. In the initial state, the outer edge of the main cutter 97 does not extend outward beyond the cutout 98. During the outward movement of the main cutter 97, the blocking plate 96 always keeps an adapted installation with the cutout 98, so as to prevent soil materials from entering the cavity 94 during the drilling process. At the same time, side cutters 99 are also provided on the two side walls of the blocking plate 96; a groove can be provided at the corresponding cutout 98, and the groove is matched with the side cutter 99. In this way, not only can the side cutter 99 be used to cut and crush obstacles during drilling, but the side cutter 99 and the cutting groove can also play a guiding role in the movement of the blocking plate 96. The rack plate 95 and the center wheel 93 are meshed and transmitted; in this way, the two rack plates 95 can be driven to move closer to or farther from each other through the forward and reverse rotation of the center wheel 93. One center wheel 93 corresponds to two groups of rack plates 95, blocking plates 96 and main cutters 97, so that the clockwise rotation of the center wheel 93 drives the two rack plates 95 to move outward synchronously, and the counterclockwise rotation of the center wheel 93 drives the two rack plates 95 to move inward synchronously.

[0035] Specific working principle: When the drill rod 22 encounters entangled obstacles or plant roots during geological exploration drilling operations, the rotation speed of the drill rod 22 will be affected and the drilling progress will be slow. At this time, the working state of the main drive-hydraulic cylinder 24 for the drill rod 22 to move downward for drilling remains unchanged, that is, the main driving force remains unchanged, and the downward movement speed of the base plate 81 will be greater than the downward movement speed of the fixed plate 21 and the drill rod 22 as a whole. That is, when the rotation speed of the drill rod 22 is obstructed and reaches the preset value, the trigger rod 84 moves downward to trigger the start trigger switch 85, and the drive motor 92 is started. In the initial state, the outer blade of the main cutter 97 does not extend outward beyond the incision 98. When the driving motor 92 starts to rotate forward, it will drive the central shaft 91 and the central wheel 93 to rotate clockwise as a whole, and then drive the two rack plates 95 meshing with it to move away from each other, that is, the rack plate 95 and the blocking plate 96 move outward as a whole, driving the main cutter 97 and the side cutter 99 to move outward to the outside of the incision 98, and in the continuous rotation operation of the drill rod 22, the winding material is cut and crushed, so that the constraint of the drill rod 22 can be released, so that the drill rod 22 increases the rotation speed and returns to the normal drilling operation level. The present invention further optimizes the structural design of the drill rod 22 and the drill bit 23, utilizes the limited space of the drill rod 22, and uses the main cutter 97 and the side cutter 99 to cooperate with each other while ensuring the normal drilling operation of the drill rod 22, which can not only effectively promote the drilling, but also crush and cut the entanglement of plant roots or waste plastics in the soil, which is more ingenious, ensures the efficient operation of the drill rod 22, and improves the drilling operation efficiency and the service life of the drill bit 23.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
