Description

Technical Field

[0001] The present invention relates to the field of laser measurement technology, in particular to a profile thickness laser measurement system for geological measurement. Background Art

[0002] An iron ore region refers to a specific area rich in iron ore resources that has undergone geological exploration and development. It serves as a vital raw material base for the steel industry. The formation of an iron ore region is closely related to factors such as geological structure, magmatic activity, and sedimentary environment. Its distribution and reserves directly impact a country's industrial development and resource security. To effectively predict the iron ore resources in an iron ore region, prospectors must survey and measure the region's topography and landforms to determine the geological structure, rock layer arrangement, and geological profiles.

[0003] Prior art, for example, includes a profile thickness measuring device for geological surveys, with authorization publication number CN118816681B. The upper end of the geological structure is secured by first and second fixing plates, while the lower end is secured by a traction rope and fixed stakes, ensuring the stability of the device. Once secured, the device can measure profiles in both sections, making it particularly suitable for areas with abrupt geological changes. The measuring scale is mounted on a universally adjustable support frame to accommodate varying geological slopes.

[0004] At present, there is still a lack of a laser measurement system that can facilitate the measurement of iron ore layers of different thicknesses. The round head rod is used to clamp the wire rope, and the lifting plate is kept perpendicular to the wire rope, so that the laser rangefinder can measure the distance measuring plate vertically, and the measurement is more accurate.

[0005] Therefore, in response to the above problems, a profile thickness laser measurement system for geological surveying is proposed to solve the above problems. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention develops a profile thickness laser measurement system for geological surveying. The invention uses a round-headed rod to clamp the wire rope, keeping the lifting plate perpendicular to the wire rope, so that the laser rangefinder can measure the distance measuring plate vertically, making the measurement more accurate.

[0007] The technical solution to the technical problem solved by the present invention is as follows: the present invention provides a profile thickness laser measurement system for geological measurement, comprising: a bracket assembly, a measuring assembly and a connecting assembly; the bracket assembly comprises an upper support and a lower support, the upper support is rotatably connected to a frame, the frame is provided with symmetrical through-holes, and the lower support is rotatably connected to a lower plate; the connecting assembly comprises a square shaft, the square shaft bearing is connected to the frame, the square shaft passes through the square holes on the central axes of two line rollers, one end of two steel wire ropes is respectively connected to the central axes of the corresponding line rollers, and the two steel wire ropes are respectively wound around the central axes of the corresponding line rollers, The two steel wire ropes are threaded through corresponding holes, with their other ends connected to the lower plate. The frame is connected to a motor, whose output shaft is connected to the square shaft. The measurement assembly includes symmetrical electric hoists and laser rangefinders, each connected to the frame. The hooks of the symmetrical electric hoists each suspend a U-shaped rope, each connected to a mounting shaft. The symmetrical mounting shafts are rotatably connected to vertical rods, each connected to a lifting plate. The lifting plate is provided with large holes corresponding to the symmetrical steel wire ropes. By utilizing the connection assembly, the position of the lower and upper supports can be adjusted when the steel wire ropes are released to accommodate measurements of different geological strata. The upper support overlaps the uppermost geological stratum, with the housing contacting the edge of the stratum and the lower support contacting the ground, completing the device's installation. The steel wire ropes are tightened by tightening them. When the electric hoist is released, the weight of the lifting platform causes it to move downward along the wire rope until it reaches the edge of the iron ore layer. The laser rangefinder then controls the measurement. The difference between the two measurements is the corresponding inclined plane length. The iron ore layer thickness is calculated based on the angle of the wire rope and trigonometric relationships.

[0008] As an optimization, the frame is connected to the housing, which is connected to symmetrical guide rods. The symmetrical guide rods pass through the I-shaped plates, which are connected to symmetrical U-shaped seats. The central axes of the symmetrical line rollers are respectively connected to the corresponding U-shaped seats with bearings. By using guide rods and U-shaped seats, the installation and rotation of the line rollers are facilitated.

[0009] As an optimization, the square shaft is connected to the active bevel gear, the housing is connected to the extension plate, the extension plate bearing is connected to the central shaft of the pinion and the large gear, the central shaft of the pinion is connected to the driven bevel gear, the driven bevel gear meshes with the active bevel gear, the large gear meshes with the pinion, the central shaft of the large gear is connected to the power wheel, the edge of the power wheel is rotatably connected to the L-arm, and the L-arm is rotatably connected to the I-plate. By adopting the meshing of bevel gears and gears, the line roller can rotate and move back and forth at the same time. The bearing at the connection between the line roller and the U-seat bearing is fixed at both ends, that is, the line roller and the U-seat do not move relative to each other, and the line roller rotates relative to the U-seat. The rotation and reciprocating movement of the line roller ensure that the contact point between the wire rope and the line roller is always facing the perforation, which facilitates the retraction and release of the wire rope.

[0010] As an optimization, it also includes an alignment assembly, which includes symmetrical crossbars, each of which is connected to a power rod, each of which is symmetrically set in the groove of the double-slotted rod. The two ends of the symmetrical crossbar are connected to the inner ring. The lifting plate is connected to symmetrical mounting rods on both sides of each large hole, each mounting rod is connected to a mounting ring, each mounting ring is connected to an eccentric bevel block, each eccentric bevel block is connected to an oblique round rod, each inner ring is rotatably connected to an outer ring, each outer ring is connected to a group of eccentric round rods, each eccentric round rod passes through a first T block, each oblique round rod passes through a second T block, each first T block is rotatably connected to a corresponding second T block, and 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 is provided with a mounting slot, in which a servo is installed. The servo is connected to the lifting plate, and the output shaft of the servo passes through the lifting plate and is connected to the center of the mounting slot. By using eccentric oblique blocks, oblique round rods and eccentric round rods, when the cross bar approaches the lifting plate, the round-headed rods twist and clamp the wire rope, so that the upper and lower adjacent round-headed rods simultaneously clamp the wire rope twisted in the same direction, and the left and right adjacent round-headed rods simultaneously clamp the wire rope twisted in opposite directions, so that the lifting plate and the wire rope remain perpendicular, and the laser rangefinder is aligned with the ranging plate, which facilitates distance measurement.

[0011] As an optimization, the lifting plate is connected to a camera, the camera is connected to a distance measuring board, and the distance measuring board is connected to a laser pointer. To facilitate confirmation, the laser pointer is turned on to form a spot on the geological layer, which facilitates the confirmation of the upper and lower edge positions of the iron ore layer. The upper and lower edge positions of the iron ore layer are observed through the camera, which facilitates measurement.

[0012] As an optimization, the upper support is provided with a straight groove, in which a first ground spike is provided, a set of second ground spikes passes through the frame, and a set of third ground spikes passes through the lower support, so as to facilitate the fixing of the upper support and the frame to the geological layer, and the fixing of the lower support to the ground.

[0013] The effects provided in the summary of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: 1. This device utilizes a wire rope to enable installation in iron ore deposits of varying thicknesses. When the wire rope is tightened and the electric hoist is released, the hoist, under the weight of the lifting platform, moves downward along the wire rope to the edge of the iron ore layer. The upper and lower edges of the iron ore layer are observed through a camera. For easy confirmation, a laser pointer is used to create a spot on the geological layer. This facilitates identification of the upper and lower edges of the iron ore layer. The laser rangefinder is then used to measure the distance to the rangefinder plate. The difference between the two measurements is the corresponding inclined plane length. The thickness of the iron ore layer is calculated based on the angle of the wire rope and trigonometric relationships.

[0014] 2. The projected axis of the inclined round rod of this device 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 round rod and the origin forms an angle with the X-axis, and the angle changes with the distance between the center of the cross section and the lifting plate, showing a non-axisymmetric distribution. The eccentric round rod and the outer ring are non-axisymmetrically distributed. When the servo rotates, the double-slot rod drives the power round rod to move, achieving symmetrical movement of the cross bars on both sides, and achieving the round head rod twisting and contacting the wire rope while approaching the lifting plate, so that the upper and lower adjacent round head rods simultaneously clamp the same direction twisting wire rope, and the left and right adjacent round head rods simultaneously clamp the opposite twisting wire rope, so that the lifting plate and the wire rope remain perpendicular, and the laser rangefinder is aligned with the distance measuring plate, which facilitates distance measurement.

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 adopting the connecting assembly 2, the position 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 is attached to the uppermost edge of the geological layer, with the housing 16 contacting the edge of the layer and the lower support 18 contacting the ground, completing the device installation. The wire rope 21 is tightened to maintain tension. When the electric hoist 31 is released, the weight of the lifting platform 36 causes it to move downward along the wire rope 21, moving it to the edge of the iron ore layer. The laser rangefinder 32 is then controlled to measure the distance. The difference between the two measurements is the corresponding inclined plane length. The iron ore layer thickness is calculated based on the angle of the wire rope 21 and trigonometric relationships.

[0028] The frame 14 is connected to the housing 16, which is connected to symmetrical guide rods 110. The symmetrical guide rods 110 respectively pass through the I-shaped plate 24, which is connected to symmetrical U-shaped seats 28. The central axes of the symmetrical line rollers 27 are respectively connected to corresponding U-shaped seats 28. The use of the guide rods 110 and U-shaped seats 28 facilitates the installation and rotation of the line rollers 27.

[0029] The lifting plate 36 is connected to a camera 39, which is connected to a distance measuring plate 37, which 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, which facilitates the confirmation of the upper and lower edge positions of the iron ore layer. The upper and lower edge positions of the iron ore layer are observed through the camera 39, which facilitates measurement.

[0030] The upper support 11 is provided with a straight groove 13, in which a first ground spike 12 is provided. A set of second ground spikes 15 passes through the frame 14, and a set of third ground spikes 19 passes through the lower support 18. This facilitates the fixing of the upper support 11 and the frame 14 to the geological layer, and the fixing of the lower support 18 to the ground.

[0031] Embodiment 1: The square shaft 2 and the central axis of the wire roller 27 are fixedly connected.

[0032] The workflow of this embodiment is: The upper support 1 is overlapped on the upper end of the geological layer so that the shell 16 contacts the edge of the geological layer and fits the side wall of the geological layer. The first ground nail 12 and the second ground nail 15 are fixed.

[0033] The motor 22 is controlled to rotate, which drives the square shaft 23 to rotate, which in turn drives the line roller 27 to rotate, thereby releasing the wire rope 21. The lower support 18 is pulled downward to contact the ground, and the third ground nail 19 is inserted into the ground to secure the device. The motor 22 is controlled to rotate in the opposite direction to tighten the wire rope 21.

[0034] During measurement, the electric hoist 31 is controlled to move the lifting plate 36 downward under the force of gravity. The upper and lower edges of the iron ore layer are observed through the camera 39. To facilitate confirmation, the laser pointer 38 is activated to form a spot on the geological layer to facilitate the confirmation of the upper and lower edges of the iron ore layer. The laser rangefinder 32 is controlled to measure the distance to the rangefinder plate 37. The difference between the two measurements is the corresponding inclined plane length. Based on the angle of the wire rope 21 and the trigonometric relationship, the thickness of the iron ore layer is calculated.

[0035] Embodiment 2: The square shaft 23 is connected to the active bevel gear 211, the housing 16 is connected to the extension plate 112, the extension plate 112 has a bearing connected to the pinion 212 and the central axis of the large gear 29, the central axis of the pinion 212 is connected to the driven bevel gear 210, the driven bevel gear 210 meshes with the active bevel gear 211, the large gear 29 meshes with the pinion 212, the central axis 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-plate 24. By adopting the meshing of bevel gears and gears, the line roller 27 can rotate and reciprocate at the same time. The bearing connection between the line roller 27 and the U-base 28 adopts a fixed bearing method at both ends, that is, the line roller 27 and the U-base 28 do not move relative to each other, and the line roller 27 rotates relative to the U-base 28. The line roller 27 rotates and reciprocates at the same time so that the contact point between the wire rope 21 and the line roller 27 is always facing the through hole 111, which facilitates the retraction and extension of the wire rope 21.

[0036] The workflow of this embodiment is: When the motor 22 rotates, the square shaft 23 drives the active bevel gear 211 to rotate, the active bevel gear 211 drives the driven 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-plate 24 to move along the guide round rod 110, the I-plate 24 drives the U-base 28 to move, and the U-base 28 drives the line roller 27 to move along the square shaft 23, so that the contact point between the wire rope 21 and the line roller 27 is always facing the through hole 111.

[0037] Embodiment 3: This embodiment is further elaborated on the basis of embodiment 1 or 2, and further includes an alignment component 4, the alignment component 4 includes symmetrical cross bars 43, the symmetrical cross bars 43 are respectively connected to the power round bars 44, the symmetrical power round bars 44 are respectively arranged in the grooves of the double-slot rods 41, the two ends of the symmetrical cross bars 43 are respectively connected to the inner ring 45, the lifting plate 36 is respectively connected to the symmetrical mounting round bars 413 on both sides of each of the large holes 312, each of the mounting round bars 413 is respectively connected to the mounting ring 49, each Each mounting ring 49 is connected to an eccentric bevel block 48, each eccentric bevel block 48 is connected to an oblique round rod 46, each inner ring 45 is rotatably connected to an outer ring 414, each outer ring 414 is connected to a group of eccentric round rods 47, each eccentric round rod 47 passes through a first T-block 411, each oblique 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 cross bars 43. The lifting plate 36 is provided with a mounting slot 311, within which a servo 42 is disposed. The servo 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 slot 311. By adopting the eccentric oblique block 48, the oblique round rod 46 and the eccentric round rod 47, when the cross bar 43 approaches the lifting plate 36, the round head rod 412 is twisted to clamp the wire rope 21, so that the upper and lower adjacent round head rods 412 simultaneously clamp the same direction twisted wire rope 21, and the left and right adjacent round head rods 412 simultaneously clamp the opposite direction twisted wire rope 21, so that the lifting plate 36 and the wire rope 21 remain perpendicular, and the laser rangefinder 32 is aligned with the distance measuring plate 37, thereby facilitating distance measurement.

[0038] The position of the eccentric bevel block 48 is as follows Figure 9As shown, the projected axis of the oblique 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 oblique circular rod 46 and the origin has an angle with the X-axis, and the angle changes with the height position of the center of the cross section (the distance from the lifting plate 36), showing a non-axisymmetric distribution. The eccentric circular rod 47 and the outer ring 414 are non-axisymmetrically distributed. When the outer ring 414 moves in the height direction, taking the downward movement as an example, the eccentric circular rod 47 moves downward, driving the first T-block 411 and the second T-block 410 to move downward. 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 part of the first T-block 411 and the center point of the circular tube part of the second T-block 410 remains unchanged. The second T-block 410 moves along the oblique circular rod 46, and its center point coincides with the center of the cross section of the oblique circular rod 46. Since the angle changes with the The height position of the center of the cross section of the oblique circular rod 46 changes, and the eccentric circular rod 47 passes through the first T block 411. Since "the length of the line connecting the center point of the circular tube part of the first T block 411 and the center point of the circular tube part of the second T block 410 remains unchanged", it will inevitably drive the eccentric circular rod 47 to swing, thereby causing the "line connecting the center point of the circular tube part of the first T block 411 and the center point of the circular tube part of the second T block 410" to rotate, causing the second T block 410 to rotate around the oblique circular rod 46, and causing the round head rod 412 to twist.

[0039] The workflow of this embodiment is: When the lifting plate 36 moves to the edge of the iron ore layer, the steering gear 42 is controlled to rotate, the steering gear 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 cross bar 43 to move, the cross bar 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 oblique rod 4 6 moves, the second T-block 410 drives the first T-block 411 to swing, the first T-block 411 drives the eccentric rod 47 to swing, the eccentric rod 47 drives the outer ring 414 to rotate, and the second T-block 410 drives the round-head rod 412 to approach the lifting plate 36 while twisting and contacting the wire rope 21, so that the upper and lower adjacent round-head rods 412 simultaneously clamp the same-direction twisted wire rope 21, and the left and right adjacent round-head rods 412 simultaneously clamp the counter-twisted wire rope 21, so that the lifting plate 36 and the wire rope 21 remain perpendicular.

[0040] This device utilizes a steel wire rope 21 to enable installation in iron ore strata of varying thickness. When the steel wire rope 21 is tightened, the electric hoist 31 is released, and under the weight of the lifting plate 36, it moves downward along the steel wire rope 21, reaching the edge of the iron ore layer. The upper and lower edges of the iron ore layer are observed using a camera 39. To facilitate confirmation, a laser pointer 38 is activated to create a light spot on the geological layer, facilitating the identification of the upper and lower edges of the iron ore layer. The laser rangefinder 32 is then controlled to measure the distance to the rangefinder plate 37. The difference between the two measurements is the corresponding inclined plane length. The thickness of the iron ore layer is calculated based on the angle of the steel wire rope 21 and trigonometric relationships.

[0041] The projected axis of the oblique circular rod 46 of this device 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 oblique circular rod 46 and the origin forms an angle with the X-axis, and the angle changes with the distance between the center of the cross section and the lifting plate 36, showing a non-axisymmetric distribution. The eccentric circular rod 47 and the outer ring 414 are non-axisymmetrically distributed. When the servo 42 rotates, the double-slotted rod 41 drives the power circular rod 44 to move, achieving symmetrical movement of the cross bars 43 on both sides, achieving the round head rod 412 approaching the lifting plate 36 while twisting and contacting the wire rope 21, achieving the upper and lower adjacent round head rods 412 to simultaneously clamp the same direction twisting wire rope 21, and the left and right adjacent round head rods 412 to simultaneously clamp the opposite twisting wire rope 21, so that the lifting plate 36 and the wire rope 21 remain perpendicular, and the laser rangefinder 32 is aligned with the distance measuring plate 37, facilitating distance measurement.

[0042] Although the above describes the specific implementation methods of the invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
