Description

Technical Field

[0001] This invention relates to the field of rock drilling technology, and in particular to a drilling measurement device for analyzing slope geological characteristics and its usage method. Background Technology

[0002] In rock drilling operations, accurate analysis and assessment of slope geological characteristics are crucial. However, existing measurement methods often require extensive manual operation, which is not only inefficient and difficult to guarantee accuracy, but also inconvenient for sample extraction. This necessitates frequent machine shutdowns for manual sampling, and the number of shutdowns increases with the drilling depth, affecting the continuity and efficiency of rock drilling operations. Furthermore, the quality of the samples cannot be guaranteed; due to instability or external interference during the sampling process, early equipment may fail to guarantee the accuracy and representativeness of the samples, affecting the reliability of subsequent analysis and processing, thus hindering sampling and testing. Summary of the Invention

[0003] To address the technical problem of inconvenient sampling and testing during existing rock drilling operations, this invention proposes a drilling-while-drilling measurement device and its usage method for slope geological characteristic analysis.

[0004] This invention proposes a drilling measurement equipment and its usage method for slope geological characteristic analysis, comprising a rock drill and a construction vehicle for installing the rock drill. The rock drill includes a construction body and a drilling rod, the drilling rod being mounted on the surface of the construction body. The lower end of the rock drill is mounted on the support arm surface of the construction vehicle. A sampling mechanism is mounted on the front end surface of the drilling rod, the sampling mechanism including a sampling cylinder, which is a circular tube open at both ends; a cleaning mechanism is mounted on the front end surface of the sampling cylinder, the cleaning mechanism wrapping around a fixed water pipe, the fixed water pipe being a partially formed circular ring; a driving mechanism is mounted on the surface of the sampling mechanism, the driving mechanism including a transmission box, the transmission box being a hollow circular ring.

[0005] Preferably, a feeding pipe is fixedly connected to the lower surface of the sampling cylinder, and a connecting groove is formed on the lower end surface of the sampling cylinder. Multiple connecting grooves are arranged in a linear array on the lower end surface of the sampling cylinder. The connecting groove connects the interior of the sampling cylinder with the interior of the feeding pipe. A stacking pipe is slidably sleeved on the inner wall of the sampling cylinder. A limiting pipe is fixedly connected to the open surface of one end of the stacking pipe. The limiting pipe is funnel-shaped. A spiral blade is fixedly connected to the surface of the construction drill rod. The construction drill rod is located inside the limiting pipe and the stacking pipe.

[0006] The above technical solution uses a material limiting tube to wrap the surface of the construction drill rod, which helps to prevent the sampling tube from falling off prematurely when the crushed stone is loose.

[0007] Preferably, a feeding groove is formed on the lower end surface of the stacking pipe, the feeding groove is located above the connecting groove, a feeding ring is fixedly connected to the inner wall of the stacking pipe, a feeding rod is fixedly connected to the inner wall of the feeding ring, and a plurality of feeding rods are arranged in a ring array with the axis of the feeding ring as the array center on the inner wall surface of the feeding ring, and the feeding rods are made of spring steel.

[0008] The above technical solution utilizes the elasticity of the feeding rod, which facilitates the bending of the feeding rod under the action of the spiral blade, thus avoiding obstruction of the rotation of the spiral blade.

[0009] Preferably, an installation ring is fixedly connected to the side wall surface of the construction machine body, a telescopic rod is provided on the side wall surface of the installation ring, a thrust spring is slidably sleeved on the movable end surface of the telescopic rod, and an insertion hole is provided on the side wall surface of the sampling cylinder, the inner wall of the insertion hole is fixedly connected to the movable end surface of the telescopic rod.

[0010] The above technical solution utilizes a telescopic rod and a thrust spring to movably install the sampling cylinder, thereby facilitating adaptation to the drilling depth of the construction drill rod.

[0011] Preferably, the surface of the fixed water pipe is fixedly connected to the outer upper surface of the sampling tube, and nozzles are installed at both ends of the fixed water pipe. The surface of the nozzle is fixedly inserted into the lower end surface of the sampling tube, and the spray nozzle is aligned with the surface of the construction drill rod. A baffle plate is fixedly connected to the front end surface of the material stacking pipe. The baffle plate is located below the material limiting pipe, and a guide groove is formed on the lower surface of the baffle plate. The ends of the two nozzles are located inside the guide groove.

[0012] The above technical solution uses a nozzle to spray water to rinse the surface of the drilling rod, which facilitates cleaning of the sampling room for multiple sampling operations.

[0013] Preferably, a feeding plate is fixedly connected to the lower surface of the sampling tube, the surface of the feeding plate is in communication with the interior of the sampling tube, and a water delivery hose is fixedly connected to the upper surface of the fixed water pipe, the end of the water delivery hose is connected to the water delivery end of the rock drill.

[0014] The above technical solution utilizes a discharge plate to remove excess gravel, thereby preventing a large amount of gravel from clogging the discharge pipe.

[0015] Preferably, the side wall surface of the mounting ring is fixedly connected to the side wall surface of the transmission box, the side wall edge of the transmission box is fixedly sleeved with the surface of the telescopic rod, and the inner wall of the transmission box is rotatably connected to a gear set through a bearing. Both gear sets include an internal gear, an external gear, and a transmission gear. The internal gear and the external gear are only provided with half-circle retaining teeth. The internal gear and the external gear are concentrically aligned, and the retaining teeth of the internal gear and the external gear are set in opposite directions. The transmission gear is located between the external gear and the internal gear.

[0016] By using the above technical solution, the internal gear and the external gear are set in opposite directions, so that only one of the internal gear or the external gear can mesh with the outer surface of the transmission gear at the same time.

[0017] Preferably, the surface of the drilling rod is fixedly sleeved with the inner wall of the external gear, and a connecting rod is fixedly connected to the side wall surface of the inner gear of both gear sets. A connecting ring is fixedly connected to the side wall surface of one of the gear sets. The connecting ring includes an inner ring, an outer ring, and a connecting rod. The side wall surface of the inner ring is fixedly connected to the side wall surface of the external gear, and the side wall surface of the outer ring is fixedly connected to the side wall surface of the inner gear.

[0018] The above technical solution utilizes a connecting ring and a connecting rod to link the two internal gears from one end of the transmission box, thereby avoiding obstruction by the sleeve.

[0019] Preferably, a sleeve is fixedly inserted into the inner wall of the transmission gear, and a rotating rod is slidably inserted into the end surface of the sleeve. The rotating rod has a rectangular cross-section, the inner wall of the sleeve is adapted to the surface of the rotating rod, a lead screw is fixedly connected to the end surface of the rotating rod, and a threaded sleeve is fixedly inserted into the surface of the stacking pipe. The inner wall of the threaded sleeve is threadedly connected to the surface of the lead screw.

[0020] The above technical solution utilizes the rectangular cross-section of the rotating rod, which facilitates the extension and retraction of the rotating rod within the sleeve, while the sleeve drives the rotating rod to rotate.

[0021] The method of use is as follows: Step 1, before use, move the rock drill to the construction site by the construction vehicle, connect the rock drill to the external water source, connect the feed pipe to the external detection equipment, and then start the rock drill to drill. The thrust spring pushes the sampling tube to press against the outside of the borehole, and the telescopic rod extends under the pull of the sampling tube. The construction machine body drives the construction drill rod to rotate.

[0022] Step 2: While drilling, the spiral blades rotate with the drilling rod, carrying out the gravel in the borehole. The limiting pipe guides the gravel into the stacking pipe. The baffle plate shields the surface of the nozzle through the guide groove. The water sprayed from the nozzle is discharged outward through the discharge plate. When the drilling rod rotates, the discharge rod scrapes the gravel off the surface of the drilling rod and accumulates in the stacking pipe.

[0023] Step 3: The construction drill rod drives the external gear in the transmission box to rotate. The external gear drives one of the internal gears to rotate through the connecting ring. Two adjacent internal gears rotate synchronously through the connecting rod. The internal gear and the external gear drive the transmission gear in turn. The two transmission gears drive the two sleeves to rotate respectively. The sleeve drives the lead screw to rotate through the rotating rod. While the lead screw rotates, it drives the stacking pipe through the threaded sleeve.

[0024] Step four: Under the alternating drive of the internal and external gears, the transmission gear drives the sleeve to frequently change its rotation direction, thereby causing the stacking pipe to reciprocate inside the sampling cylinder. At the same time, the lower surface of the stacking pipe pushes the crushed stone accumulated inside the sampling cylinder into the connecting groove and into the discharge pipe for sampling and testing. When the stacking cylinder moves the baffle plate away from the surface of the nozzle, the water jet from the nozzle is sprayed directly onto the surface of the construction drill rod, and the crushed stone on the surface of the construction drill rod is washed off and discharged through the discharge plate.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. By installing a sampling mechanism on the surface of the drilling rod, the spiral blades in the sampling mechanism are used to take samples, while the lead screw and threaded sleeve in the drive mechanism drive the material stacking pipe in the sampling mechanism to reciprocate. This facilitates the pushing of the sample and promotes the sample to enter the feeding pipe. That is, the sample is automatically extracted when the rock drill is working, and the sample extraction efficiency is improved with the working frequency of the drilling rod. Thus, the sampling mechanism has the characteristics of facilitating sample extraction.

[0027] 2. By installing a drive mechanism on the surface of the sampling mechanism, the gear set in the drive mechanism lifts the construction drill rod and rotates it, while simultaneously driving the material stacking pipe in the sampling mechanism to reciprocate. This facilitates the synchronous operation of the drive mechanism and the rock drill, avoiding the need for an external power source.

[0028] 3. By setting the baffle plate to repeatedly block the surface of the nozzle as the material stacking pipe reciprocates within the sampling tube, the water spray from the nozzle intermittently washes the surface of the drilling rod, thus preventing continuous feeding of material into the material stacking pipe. This ensures the independence of adjacent sampling sessions, avoids mutual interference between samples, and improves the accuracy of the test. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Reference Figures 1-9A drilling measurement device for slope geological characteristic analysis and its usage method include a rock drill 1 and a construction vehicle 2 for installing the rock drill 1. The rock drill 1 includes a construction body 11 and a construction drill rod 12. The construction drill rod 12 is installed on the surface of the body. The lower end of the rock drill 1 is installed on the support arm surface of the construction vehicle 2. A sampling mechanism is installed on the front end surface of the construction drill rod 12. The sampling mechanism includes a sampling cylinder 3, which is a circular tube open at both ends. A cleaning mechanism is installed on the front end surface of the sampling cylinder 3. The cleaning mechanism wraps around a fixed water pipe 4, which is a broken circular ring. A driving mechanism is installed on the surface of the sampling mechanism. The driving mechanism includes a transmission box 5, which is a hollow circular ring.

[0041] For sampling, a feeding pipe 31 is fixedly connected to the lower surface of the sampling cylinder 3. A connecting groove is formed on the lower end surface of the sampling cylinder 3, and multiple connecting grooves are arranged in a linear array on the lower end surface of the sampling cylinder 3. The connecting groove connects the interior of the sampling cylinder 3 to the interior of the feeding pipe 31. A stacking pipe 32 is slidably sleeved on the inner wall of the sampling cylinder 3. A limiting pipe 33 is fixedly connected to the open surface of one end of the stacking pipe 32. The limiting pipe 33 is funnel-shaped. A spiral blade 34 is fixedly connected to the surface of the construction drill rod 12. The construction drill rod 12 is located inside the limiting pipe 33 and the stacking pipe 32. The limiting pipe 33 is used to control the flow of the construction drill rod 12. The surface is wrapped to prevent premature detachment from the front end of the sampling tube 3 when the crushed stone is loose. A feeding groove is opened on the lower end surface of the stacking pipe 32, which is located above the connecting groove. A feeding ring 35 is fixedly connected to the inner wall of the stacking pipe 32, and a feeding rod 36 is fixedly connected to the inner wall of the feeding ring 35. Multiple feeding rods 36 are arranged in a ring array with the axis of the feeding ring 35 as the array center on the inner wall surface of the feeding ring 35. The feeding rods 36 are made of spring steel. The feeding rods 36 have a certain degree of elasticity, which makes it easy for the feeding rods 36 to bend under the action of the spiral blade 34, thus avoiding obstructing the rotation of the spiral blade 34.

[0042] To facilitate sample removal, an installation ring 37 is fixedly connected to the side wall surface of the construction machine body 11. A telescopic rod 38 is provided on the side wall surface of the installation ring 37. A thrust spring 39 is slidably sleeved on the movable end surface of the telescopic rod 38. An insertion hole is provided on the side wall surface of the sampling cylinder 3. The inner wall of the insertion hole is fixedly connected to the movable end surface of the telescopic rod 38. The sampling cylinder 3 is movably installed using the telescopic rod 38 and the thrust spring 39, thereby facilitating adaptation to the drilling depth of the construction drill rod 12.

[0043] By installing a sampling mechanism on the surface of the construction drill rod 12, the spiral blade 34 in the sampling mechanism is used to take samples while the lead screw 56 and threaded sleeve 57 in the drive mechanism drive the material stacking pipe 32 in the sampling mechanism to reciprocate, which facilitates the pushing of the sample and promotes the sample to enter the feed pipe 31. That is, the sample is automatically extracted when the rock drill 1 is working, and the sample extraction efficiency is improved with the working frequency of the construction drill rod 12, thus making the sampling mechanism easy to extract samples.

[0044] To clean the surface of the drilling rod 12, a fixed water pipe 4 is fixedly connected to the outer upper surface of the sampling cylinder 3. Both ends of the fixed water pipe 4 are equipped with nozzles 41, whose surfaces are fixedly inserted into the lower surface of the sampling cylinder 3. The nozzle orifices of the nozzles 41 are aligned with the surface of the drilling rod 12. A baffle plate 42 is fixedly connected to the front end of the material stacking pipe 32, located below the material limiting pipe 33. A guide groove 43 is formed on the lower surface of the baffle plate 42. The ends of the two nozzles 41... Located inside the guide channel 43, the nozzle 41 sprays water to wash the surface of the construction drill rod 12, which facilitates cleaning of the sampling room multiple times. The lower surface of the sampling tube 3 is fixedly connected to the discharge plate 44, and the surface of the discharge plate 44 is connected to the inside of the sampling tube 3. The upper surface of the fixed water pipe 4 is fixedly connected to the water supply hose 45, and the end of the water supply hose 45 is connected to the water supply end of the rock drill 1. The discharge plate 44 is used to discharge excess gravel, which helps to avoid a large amount of gravel clogging the discharge pipe 31.

[0045] By installing a drive mechanism on the surface of the sampling mechanism, the gear set 51 in the drive mechanism lifts the construction drill rod 12 and rotates it, while simultaneously driving the material stacking pipe 32 in the sampling mechanism to reciprocate. This facilitates the synchronous operation of the drive mechanism and the rock drill 1, avoiding the need for an external power source.

[0046] To drive the sampling device, the side wall surface of the mounting ring 37 is fixedly connected to the side wall surface of the transmission box 5. The edge of the side wall of the transmission box 5 is fixedly sleeved with the surface of the telescopic rod 38. The inner wall of the transmission box 5 is rotatably connected to a gear set 51 via bearings. Each gear set 51 includes an internal gear 511, an external gear 512, and a transmission gear 513. Both the internal gear 511 and the external gear 512 have only half-turn teeth. The internal gear 511 and the external gear 512 are concentrically aligned, and the teeth of the internal gear 511 and the external gear 512 are set in opposite directions. The transmission gear 513 is located between the external gear 512 and the internal gear 511. By utilizing the opposite directions of the teeth of the internal gear 511 and the external gear 512, ... To ensure that only one of the internal gear 511 or the external gear 512 meshes with the outer surface of the transmission gear 513 at any given time, the surface of the construction drill rod 12 is fixedly sleeved with the inner wall of the external gear 512, and connecting rods 52 are fixedly connected to the side wall surfaces of the internal gears 511 of both gear sets 51. A connecting ring 53 is fixedly connected to the side wall surface of one of the gear sets 51. The connecting ring 53 includes an inner ring, an outer ring, and a connecting rod. The side wall surface of the inner ring is fixedly connected to the side wall surface of the external gear 512, and the side wall surface of the outer ring is fixedly connected to the side wall surface of the internal gear 511. The two internal gears 511 are linked from one end of the transmission box 5 using the connecting ring 53 and the connecting rod, thereby avoiding obstruction by the sleeve 54.

[0047] To transmit power to the sampling mechanism, a sleeve 54 is fixedly inserted into the inner wall of the transmission gear 513. A rotating rod 55 is slidably inserted into the end surface of the sleeve 54. The rotating rod 55 has a rectangular cross-section. The inner wall of the sleeve 54 is adapted to the surface of the rotating rod 55. A lead screw 56 is fixedly connected to the end surface of the rotating rod 55. A threaded sleeve 57 is fixedly inserted into the surface of the stacking pipe 32. The inner wall of the threaded sleeve 57 is threadedly connected to the surface of the lead screw 56. The rectangular cross-section of the rotating rod 55 facilitates the rotation of the rotating rod 55 while it extends and retracts within the sleeve 54. The sleeve 54 drives the rotating rod 55 to rotate.

[0048] By setting the material stacking pipe 32 to reciprocate within the sampling cylinder 3, the baffle plate 42 is driven to repeatedly block the surface of the nozzle 41, thereby causing the nozzle 41 to intermittently spray water to wash the surface of the construction drill rod 12. This avoids continuous feeding of material into the material stacking pipe 32, thus ensuring the independence of adjacent sampling sessions, preventing mutual interference between samples, and improving the accuracy of the test.

[0049] Working principle:

[0050] Step 1: Before use, move the rock drill 1 to the construction site using the construction vehicle 2, connect the rock drill 1 to the external water source, connect the feed pipe 31 to the external testing equipment, and then start the rock drill 1 to drill. The thrust spring 39 pushes the sampling cylinder 3 to press against the outside of the borehole, and the telescopic rod 38 extends under the pull of the sampling cylinder 3. The construction machine body 11 drives the construction drill rod 12 to rotate.

[0051] Step 2: While drilling, the spiral blade 34 rotates with the drilling rod 12, carrying out the gravel in the hole. The limiting pipe 33 guides the gravel into the stacking pipe 32. The baffle plate 42 shields the surface of the nozzle 41 through the guide groove 43. The water sprayed from the nozzle 41 is discharged outward through the discharge plate 44. When the drilling rod 12 rotates, the discharge rod 36 scrapes the gravel off the surface of the drilling rod 12 and accumulates it in the stacking pipe 32.

[0052] Step 3: The construction drill rod 12 drives the external gear 512 in the transmission box 5 to rotate. The external gear 512 drives one of the internal gears 511 to rotate through the connecting ring 53. The two adjacent internal gears 511 rotate synchronously through the connecting rod 52. The internal gear 511 and the external gear 512 drive the transmission gear 513 in turn. The two transmission gears 513 drive the two sleeves 54 to rotate respectively. The sleeves 54 drive the lead screw 56 to rotate through the rotating rod 55. While the lead screw 56 rotates, it drives the stacking pipe 32 through the threaded sleeve 57.

[0053] Step four: Under the alternating drive of the internal gear 511 and the external gear 512, the transmission gear 513 drives the sleeve 54 to frequently change its rotation direction, thereby driving the stacking pipe 32 to reciprocate within the sampling cylinder 3. At the same time, the lower end surface of the stacking pipe 32 pushes the accumulated gravel inside the sampling cylinder 3 into the connecting groove and into the discharge pipe 31 for sampling and testing. When the stacking pipe moves the baffle plate 42 away from the surface of the nozzle 41, the water jet from the nozzle 41 sprays directly onto the surface of the construction drill rod 12, and the gravel on the surface of the construction drill rod 12 is washed off and discharged through the discharge plate 44.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The method of using a drilling measurement device for slope geological characteristic analysis according to claim 6 is as follows: Step 1, before use, the rock drill (1) is moved to the construction site by the construction vehicle (2), the rock drill (1) is connected to the external water source, the feed pipe (31) is connected to the external detection equipment, and then the rock drill (1) is started to drill. The thrust spring (39) pushes the sampling tube (3) to press against the outside of the borehole, the telescopic rod (38) is extended under the pull of the sampling tube (3), and the construction machine body (11) drives the construction drill rod (12) to rotate. Step 2: While drilling, the spiral blade (34) rotates with the drilling rod (12) and carries out the crushed stone in the hole. The limiting pipe (33) guides the crushed stone into the stacking pipe (32). The baffle plate (42) shields the surface of the nozzle (41) through the guide groove (43). The water sprayed from the nozzle (41) is discharged outward through the discharge plate (44). When the drilling rod (12) rotates, the discharge rod (36) scrapes the crushed stone off the surface of the drilling rod (12) and accumulates it in the stacking pipe (32). Step 3: The construction drill rod (12) drives the external gear (512) in the transmission box (5) to rotate. The external gear (512) drives one of the internal gears (511) to rotate through the connecting ring (53). The two adjacent internal gears (511) rotate synchronously through the connecting rod (52). The internal gear (511) and the external gear (512) drive the transmission gear (513) in turn. The two transmission gears (513) drive the two sleeves (54) to rotate respectively. The sleeves (54) drive the lead screw (56) to rotate through the rotating rod (55). While the lead screw (56) rotates, it drives the stacking pipe (32) through the threaded sleeve (57). Step four, and under the alternating drive of the internal gear (511) and the external gear (512), the transmission gear (513) drives the sleeve (54) to frequently change the rotation direction, thereby driving the stacking pipe (32) to reciprocate in the sampling cylinder (3). At the same time, the lower end surface of the stacking pipe (32) pushes the crushed stone accumulated inside the sampling cylinder (3) into the connecting groove and enters the discharge pipe (31) for sampling and testing. When the stacking cylinder drives the baffle plate (42) to move away from the surface of the nozzle (41), the water jet from the nozzle (41) sprays directly onto the surface of the construction drill rod (12), and the crushed stone on the surface of the construction drill rod (12) is washed off and discharged through the discharge plate (44).
