Description
Technical Field
[0001] This invention relates to the field of laser measurement technology, and in particular to a laser measurement system for profile thickness in geological surveying. Background Technology
[0002] Iron ore areas refer to specific regions rich in iron ore resources that have undergone geological exploration and development, serving as important raw material bases for the steel industry. The formation of iron ore areas is closely related to factors such as geological structure, magmatic activity, and sedimentary environment. To effectively predict iron ore resources in these areas, exploration personnel need to investigate and measure the topography and geomorphology of the region to determine its geological structure, rock layer arrangement, and geological profiles.
[0003] Existing technology, such as the invention of a profile thickness measuring device for geological surveying, authorized publication number CN118816681B, uses a first and second fixing plate to fix the upper end of the geological geology, and then uses a traction rope and fixing piles to fix the lower end of the geological geology, ensuring the stability of the device. After the device is fixed, the profiles of both parts can be measured, which is especially suitable for areas where the geological arrangement drops sharply. The measuring ruler is set on a support frame, and the support frame is universally adjustable to adapt to geological conditions with different slopes.
[0004] Currently, there is a lack of laser measurement systems that can facilitate the measurement of iron ore layers of different thicknesses. By using a round-headed rod to clamp the steel wire rope and keeping the lifting plate perpendicular to the steel wire rope, the laser rangefinder can be used to measure the rangefinder plate perpendicularly, resulting in more accurate measurements.
[0005] Therefore, to address the above problems, a laser measurement system for geological profile thickness is proposed. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention develops a laser measurement system for geological profile thickness. This invention utilizes a round-headed rod to clamp a steel wire rope, keeping the lifting plate perpendicular to the steel wire rope, thus enabling the laser rangefinder to measure the rangefinder plate perpendicularly, resulting in more accurate measurements.
[0007] The technical solution to the technical problem solved by this invention is as follows: This invention provides a laser profile thickness measurement system for geological surveying, comprising: a support assembly, a measurement assembly, and a connecting assembly; the support assembly includes an upper support and a lower support, the upper support being rotatably connected to a frame, the frame having symmetrical through holes, and the lower support being rotatably connected to a lower plate; the connecting assembly includes a square shaft, the square shaft bearing connecting to the frame, the square shaft passing through square holes on the central shafts of two linear rollers, one end of two steel wire ropes respectively connected to the central shafts of the corresponding linear rollers, and the two steel wire ropes respectively wound around the central shafts of the corresponding linear rollers. Two steel wire ropes pass through corresponding holes, and the other ends of the two steel wire ropes are connected to the lower plate. The frame is connected to a motor, and the output shaft of the motor is connected to the square shaft. The measuring assembly includes symmetrical electric hoists and laser rangefinders. The symmetrical electric hoists and laser rangefinders are connected to the frame. The hooks of the symmetrical electric hoists suspend U-shaped ropes, and the symmetrical U-shaped ropes are connected to mounting shafts. The symmetrical mounting shafts are rotatably connected to vertical rods, and the symmetrical vertical rods are connected to lifting plates. The lifting plates have large holes corresponding to the symmetrical steel wire ropes. By using a connecting assembly, the positions of the lower and upper supports can be adjusted when the steel wire ropes are released to adapt to the measurement of different geological layers. The upper support overlaps the uppermost part of the geological layer, so that the shell contacts the edge of the geological layer, and the lower support contacts the ground, thus realizing the installation of the device. The steel wire ropes are tightened to make them taut. When the electric hoist is released, the lifting plate moves downwards along the wire rope under the force of gravity, until it reaches the edge of the iron ore layer. A laser rangefinder is then used to measure the difference between two measurements, which represents the length of the inclined plane. Based on the angle of the wire rope and trigonometric relationships, the thickness of the iron ore layer is calculated.
[0008] As an optimization, the frame is connected to the housing, and the housing is connected to symmetrical guide rods. The symmetrical guide rods pass through I-beams, and the I-beams are connected to symmetrical U-shaped seats. The central shafts of the symmetrical rollers are respectively bearing-connected to the corresponding U-shaped seats. By using guide rods and U-shaped seats, the installation and rotation of the rollers are facilitated.
[0009] As an optimization, the square shaft connects to the driving bevel gear, the housing connects to the extension plate, the extension plate bearing connects to the central shafts of the pinion and the large gear, the central shaft of the pinion connects to the driven bevel gear, the driven bevel gear meshes with the driving bevel gear, the large gear meshes with the pinion, the central shaft of the large gear connects to the drive wheel, the edge of the drive wheel is rotatably connected to an L-arm, and the L-arm is rotatably connected to the I-beam. By employing bevel gear meshing and gear meshing, the wire roller rotates and reciprocates simultaneously. At the connection between the wire roller and the U-shaped seat bearing, the bearing is fixed at both ends, meaning there is no relative movement between the wire roller and the U-shaped seat, but the wire roller rotates relative to the U-shaped seat. The simultaneous rotation and reciprocating movement of the wire roller ensures that the contact point between the wire rope and the wire roller always faces the through hole, facilitating the winding and unwinding of the wire rope.
[0010] As an optimization, an alignment component is also included. This alignment component comprises symmetrical crossbars, each connected to a power rod. The symmetrical power rods are respectively positioned within the slots of the double-groove rods. Both ends of the symmetrical crossbars are connected to inner rings. Symmetrical mounting rods are connected to both sides of each large hole on the lifting plate. Each mounting rod is connected to a mounting ring. Each mounting ring is connected to an eccentric inclined block. Each eccentric inclined block is connected to an inclined rod. Each inner ring is rotatably connected to an outer ring. Each outer ring is connected to a set of eccentric rods. Each eccentric rod passes through a first T-block. Each inclined rod passes through a second T-block. Each first T-block is rotatably connected to a corresponding second T-block. Each first T-block is connected to a round-head rod. The lifting plate is connected to symmetrical guide vertical rods, which pass through the symmetrical crossbars. The lifting plate has a mounting slot, within which a servo motor is installed. The servo motor is connected to the lifting plate, and its output shaft passes through the lifting plate and is connected to the center of the mounting slot. By employing eccentric inclined blocks, inclined round rods, and eccentric round rods, the round-headed rods twist when the crossbar approaches the lifting plate, clamping the wire rope. This allows adjacent round-headed rods above and below to simultaneously clamp the wire rope twisting in the same direction, while adjacent round-headed rods to the left and right simultaneously clamp the wire rope twisting in the opposite direction. This keeps the lifting plate perpendicular to the wire rope, allowing the laser rangefinder to be aligned with the rangefinder plate for convenient distance measurement.
[0011] As an optimization, the lifting plate is connected to a camera, the camera is connected to a ranging plate, and the ranging plate is connected to a laser pointer. To facilitate confirmation, the laser pointer is turned on to create a light spot on the geological layer, making it easier to identify the upper and lower edges of the iron ore layer. The upper and lower edges of the iron ore layer are then observed through the camera for convenient measurement.
[0012] As an optimization, the upper support is provided with a straight groove, in which a first ground stake is installed. A set of second ground stakes passes through the frame, and a set of third ground stakes passes through the lower support. This facilitates the fixing of the upper support and frame to the geological layer, as well as the fixing of the lower support to the ground.
[0013] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:
[0014] 1. This device utilizes a steel wire rope for installation on iron ore geological layers of varying thicknesses. When the steel wire rope is taut, the electric hoist extends, and under the weight of the lifting plate, it moves downwards along the steel wire rope to the edge of the iron ore layer. A camera observes the upper and lower edges of the iron ore layer. To facilitate confirmation, a laser pointer is used to create a light spot on the geological layer, allowing for easy identification of the upper and lower edges. The distance between the laser rangefinder and the measuring plate is controlled, and the difference between the two measurements represents the corresponding slope length. Based on the angle of the steel wire rope and trigonometric relationships, the thickness of the iron ore layer is calculated.
[0015] 2. The projected axis of the inclined circular rod in this device does not pass through the origin in the horizontal plane. At each height position, the line connecting the center of the inclined circular rod's cross-section to the origin makes an angle with the X-axis, and this angle varies with the distance between the cross-section center and the lifting plate, exhibiting a non-axisymmetric distribution. The eccentric circular rod and the outer ring also exhibit a non-axisymmetric distribution. When the servo motor rotates, the double-grooved rod drives the power circular rod to move, achieving symmetrical movement of the two horizontal rods. This allows the circular rod to approach the lifting plate while simultaneously twisting the contact wire rope. Adjacent circular rods above and below simultaneously clamp the wire rope twisting in the same direction, while adjacent circular rods to the left and right simultaneously clamp the wire rope twisting in the opposite direction, keeping the lifting plate perpendicular to the wire rope and aligning the laser rangefinder with the rangefinder plate for convenient distance measurement.

[0032] like Figures 1 to 9As shown, a laser profile thickness measurement system for geological surveying includes: a support assembly 1, a measurement assembly 3, and a connecting assembly 2. The support assembly 1 includes an upper support 11 and a lower support 18. The upper support 11 is rotatably connected to a frame 14, and the frame 14 is provided with symmetrical through holes 111. The lower support 18 is rotatably connected to a lower plate 17. The connecting assembly 2 includes a square shaft 23, which is bearing-connected to the frame 14. The square shaft 23 passes through square holes on the central shafts of two rollers 27. One end of each of two steel wire ropes 21 is connected to the central shaft of the corresponding roller 27. The two steel wire ropes 21 are wound around the central shaft of the corresponding roller 27 and pass through the corresponding... The perforation 111 is used to connect the other ends of the two steel wire ropes 21 to the lower plate 17. The frame 14 is connected to the motor 22, and the output shaft of the motor 22 is connected to the square shaft 23. The measuring component 3 includes symmetrical electric hoists 31 and laser rangefinders 32. The symmetrical electric hoists 31 and laser rangefinders 32 are respectively connected to the frame 14. The hooks of the symmetrical electric hoists 31 respectively suspend U-shaped ropes 33, and the symmetrical U-shaped ropes 33 are respectively connected to the mounting shafts 34. The symmetrical mounting shafts 34 are respectively rotatably connected to vertical rods 35, and the symmetrical vertical rods 35 are respectively connected to lifting plates 36. The lifting plates 36 are respectively provided with large holes 312 corresponding to the symmetrical steel wire ropes 21. By using the connecting component 2, the positions of the lower support 18 and the upper support 11 can be adjusted when the steel wire ropes 21 are released to adapt to the measurement of different geological layers. The upper support 1 overlaps the uppermost part of the geological layer, causing the shell 16 to contact the edge of the geological layer, while the lower support 18 contacts the ground, thus achieving the installation of the device. The steel wire rope 21 is tightened. When the electric hoist 31 is released, under the gravity of the lifting plate 36, it moves downwards along the steel wire rope 21, reaching the edge of the iron ore layer. The laser rangefinder 32 measures the difference between two measurements, which is the corresponding length of the inclined plane. Based on the angle of the steel wire rope 21 and using trigonometric relationships, the thickness of the iron ore layer is calculated.
[0033] The frame 14 is connected to the housing 16, and the housing 16 is connected to symmetrical guide rods 110. The symmetrical guide rods 110 pass through the I-beam 24, and the I-beam 24 is connected to symmetrical U-shaped seats 28. The central shafts of the symmetrical rollers 27 are respectively bearing-connected to the corresponding U-shaped seats 28. By using guide rods 110 and U-shaped seats 28, the installation and rotation of the rollers 27 are facilitated.
[0034] The lifting plate 36 is connected to a camera 39, the camera 39 is connected to a ranging plate 37, and the ranging plate 37 is connected to a laser pointer 38. To facilitate confirmation, the laser pointer 38 is turned on to form a light spot on the geological layer, making it easier to determine the upper and lower edges of the iron ore layer. The upper and lower edges of the iron ore layer are observed through the camera 39, facilitating measurement.
[0035] The upper support 11 is provided with a straight groove 13, in which a first ground nail 12 is installed. A set of second ground nails 15 passes through the frame 14, and a set of third ground nails 19 passes through the lower support 18. This facilitates the fixing of the upper support 11 and frame 14 to the geological layer, and the fixing of the lower support 18 to the ground.
[0036] Example 1: The square shaft 2 and the central shaft of the wire roller 27 are fixedly connected.
[0037] The workflow of this embodiment is as follows:
[0038] Place the upper support 1 onto the top of the geological layer, so that the shell 16 contacts the edge of the geological layer and fits against the side wall of the geological layer. Secure the first ground stake 12 and the second ground stake 15.
[0039] The control motor 22 rotates, which drives the square shaft 23 to rotate, and the square shaft 23 drives the wire roller 27 to rotate, thereby releasing the wire rope 21 and pulling down the support 18 to make it contact the ground. The third ground nail 19 is then inserted into the ground to fix the device. The control motor 22 rotates in the opposite direction to tighten the wire rope 21.
[0040] During measurement, the electric hoist 31 is operated, and under the gravity of the lifting plate 36, etc., the lifting plate 36 moves downward. The upper and lower edges of the iron ore layer are observed through the camera 39. To facilitate confirmation, a laser pointer 38 is turned on to form a light spot on the geological layer, making it easier to confirm the upper and lower edges of the iron ore layer. The laser rangefinder 32 is controlled to measure the distance between itself and the measuring plate 37. The difference between the two measurements is the corresponding slope length. Based on the angle of the wire rope 21, the thickness of the iron ore layer is calculated according to trigonometric functions.
[0041] Example 2: The square shaft 23 is connected to the driving bevel gear 211, the housing 16 is connected to the extension plate 112, the extension plate 112 is bearing-connected to the central shaft of the pinion 212 and the large gear 29, the central shaft of the pinion 212 is connected to the driven bevel gear 210, the driven bevel gear 210 meshes with the driving bevel gear 211, the large gear 29 meshes with the pinion 212, the central shaft of the large gear 29 is connected to the power wheel 25, the edge of the power wheel 25 is rotatably connected to the L-arm 26, and the L-arm 26 is rotatably connected to the I-beam plate 24. By using bevel gear meshing and gear meshing, the wire roller 27 rotates and reciprocates simultaneously. At the bearing connection between the wire roller 27 and the U-seat 28, the bearing is fixed at both ends, that is, the wire roller 27 and the U-seat 28 do not move relative to each other, the wire roller 27 rotates relative to the U-seat 28. The rotating roller 27 moves back and forth, ensuring that the contact point between the wire rope 21 and the roller 27 always faces the through hole 111, which facilitates the winding and unwinding of the wire rope 21.
[0042] The workflow of this embodiment is as follows:
[0043] When the motor 22 rotates, the square shaft 23 drives the driving bevel gear 211 to rotate, the driving bevel gear 210 and the pinion 212 to rotate, the pinion 212 drives the large gear 29 and the power wheel 25 to rotate, the power wheel 25 drives the L-arm 26 to swing, the L-arm 26 drives the I-beam 24 to move along the guide rod 110, the I-beam 24 drives the U-seat 28 to move, and the U-seat 28 drives the wire roller 27 to move along the square shaft 23, so that the contact point between the wire rope 21 and the wire roller 27 always faces the through hole 111.
[0044] Example 3: This example further elaborates on Example 1 or 2, and also includes an alignment component 4. The alignment component 4 includes symmetrical crossbars 43, each of which is connected to a power rod 44. The symmetrical power rods 44 are respectively disposed in the grooves of the double-groove rods 41. The two ends of the symmetrical crossbars 43 are respectively connected to inner rings 45. The lifting plate 36 is connected to symmetrical mounting rods 413 on both sides of each large hole 312. Each mounting rod 413 is connected to a mounting ring 49. Each of the mounting rings 49 is connected to an eccentric inclined block 48, each eccentric inclined block 48 is connected to an inclined round rod 46, each inner ring 45 is rotatably connected to an outer ring 414, each outer ring 414 is connected to a set of eccentric round rods 47, each eccentric round rod 47 passes through a first T-block 411, each inclined round rod 46 passes through a second T-block 410, each first T-block 411 is rotatably connected to a corresponding second T-block 410, and each first T-block 411 is connected to a round-headed rod 412. The lifting plate 36 is connected to symmetrical guide vertical rods 310, which pass through symmetrical horizontal rods 43. The lifting plate 36 is provided with a mounting groove 311, in which a servo motor 42 is provided. The servo motor 42 is connected to the lifting plate 36, and its output shaft passes through the lifting plate 36 and is connected to the center of the mounting groove 311. By employing eccentric inclined blocks 48, inclined round rods 46, and eccentric round rods 47, when the crossbar 43 approaches the lifting plate 36, the round-headed rod 412 twists, clamping the wire rope 21. This allows adjacent round-headed rods 412 to simultaneously clamp the wire rope 21 twisting in the same direction, and adjacent round-headed rods 412 to simultaneously clamp the wire rope 21 twisting in the opposite direction. This keeps the lifting plate 36 perpendicular to the wire rope 21, allowing the laser rangefinder 32 to be aligned with the rangefinder plate 37, facilitating distance measurement.
[0045] The position of the eccentric inclined block 48 is as follows Figure 9As shown, the projection axis of the inclined circular rod 46 in the horizontal plane does not pass through the origin. At each height position, the line connecting the center of the cross-section of the inclined circular rod 46 to the origin makes an angle with the X-axis, and this angle changes with the height position of the cross-section center (distance from the lifting plate 36), exhibiting a non-axisymmetric distribution. The eccentric circular rod 47 and the outer ring 414 also exhibit a non-axisymmetric distribution. When the outer ring 414 moves along the height direction, taking downward movement as an example, the eccentric circular rod 47 moves downward, causing the first T-block 411 and the second T-block 410 to move downwards. The first T-block 411 and the second T-block 410 are connected by rotation. The length of the line connecting the center point of the circular tube portion of the first T-block 411 and the center point of the circular tube portion of the second T-block 410 remains constant. The second T-block 410 moves along the inclined circular rod 46, and its center point coincides with the center of the cross-section of the inclined circular rod 46. Since the angle changes with the height position of the cross-section, the angle changes with the distance from the origin to the origin. The height of the center of the oblique round rod 46 changes with the position of the cross section. The eccentric round rod 47 passes through the first T-block 411. Since "the length of the line connecting the center point of the round tube part of the first T-block 411 and the center point of the round tube part of the second T-block 410 remains unchanged", it will inevitably cause the eccentric round rod 47 to swing, thereby causing "the line connecting the center point of the round tube part of the first T-block 411 and the center point of the round tube part of the second T-block 410 to rotate, causing the second T-block 410 to rotate around the oblique round rod 46, causing the round-headed rod 412 to twist.
[0046] The workflow of this embodiment is as follows:
[0047] When the lifting plate 36 moves to the edge of the iron ore layer, the control servo motor 42 rotates. The servo motor 42 drives the double-grooved rod 41 to swing. The double-grooved rod 41 drives the power rod 44 to move along the groove of the double-grooved rod 41. The power rod 44 drives the crossbar 43 to move. The crossbar 43 drives the inner ring 45 to move. The inner ring 45 drives the outer ring 414 to move. The outer ring 414 drives the eccentric rod 47 to move. The eccentric rod 47 drives the first T-block 411 to move. The first T-block 411 drives the second T-block 410 to move along the inclined rod 410. 6. Move, the second T block 410 drives the first T block 411 to swing, the first T block 411 drives the eccentric round rod 47 to swing, the eccentric round rod 47 drives the outer ring 414 to rotate, the second T block 410 drives the round head rod 412 to approach the lifting plate 36 and twist the contact wire rope 21 at the same time, so that the upper and lower adjacent round head rods 412 simultaneously clamp the wire rope 21 to twist in the same direction, and the left and right adjacent round head rods 412 simultaneously clamp the wire rope 21 to twist in the opposite direction, so that the lifting plate 36 and the wire rope 21 remain perpendicular.
[0048] This device utilizes a steel wire rope 21 to install itself on iron ore geological layers of varying thicknesses. When the steel wire rope 21 is taut, the electric hoist 31 extends, and under the weight of the lifting plate 36, it moves downwards along the steel wire rope 21 to the edge of the iron ore layer. The upper and lower edges of the iron ore layer are observed through a camera 39. To facilitate confirmation, a laser pointer 38 is activated to create a light spot on the geological layer, allowing for easy identification of the upper and lower edges. A laser rangefinder 32 measures the distance between itself and the measuring plate 37; the difference between the two measurements represents the corresponding slope length. Based on the angle of the steel wire rope 21, the thickness of the iron ore layer is calculated using trigonometric relationships.
[0049] The inclined circular rod 46 of this device projects its axis in the horizontal plane without passing through the origin. At each height position, the line connecting the center of the cross-section of the inclined circular rod 46 to the origin forms an angle with the X-axis, and this angle varies with the distance between the center of the cross-section and the lifting plate 36, exhibiting a non-axisymmetric distribution. The eccentric circular rod 47 and the outer ring 414 are also non-axisymmetrically distributed. When the servo motor 42 rotates, the double-grooved rod 41 drives the power circular rod 44 to move, achieving symmetrical movement of the two side crossbars 43. This allows the circular rod 412 to approach the lifting plate 36 while simultaneously twisting and contacting the wire rope 21. Adjacent circular rods 412 vertically clamp the wire rope 21 in the same direction of twisting, and adjacent circular rods 412 horizontally clamp the wire rope 21 in the opposite direction of twisting, keeping the lifting plate 36 perpendicular to the wire rope 21. This ensures that the laser rangefinder 32 is aligned with the rangefinder plate 37, facilitating distance measurement.
[0050] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
