Description

Technical Field

[0001] The present invention relates to the technical field of road planning surveying and mapping, and more particularly, to a road planning surveying and mapping device. Background Art

[0002] Road planning surveying and mapping is a very crucial preliminary work in road planning, which mainly includes accurately measuring and mapping the terrain, landforms, and ground features along the planned road. By using various surveying instruments and technologies, such as total stations, GPS positioning systems, levels, etc., elevation data, plane coordinates, control point positions, and other information of the road area are obtained.

[0003] When existing equipment is in use, it is usually necessary to pre-calculate the centering control points of the device. When the device is performing surveying and mapping, it needs to be vertically aligned with the centering control points. However, during the centering operation, when judging whether it is centered with the centering control points by the method of laser irradiation, due to the small laser spot, while the staff is making fine adjustments, they also need to spend mental effort to carefully identify, which is not convenient for the staff to use. And sometimes the ground of the preset point is uneven, and during the surveying and mapping process, the device is likely to collapse due to unstable support or shake, affecting the surveying and mapping accuracy.

[0010] In a preferred embodiment, an attachment rod is fixedly installed on the surface of the first support plate, a moving cavity is opened on one side of the attachment rod close to the second support plate, a limiting rod is slidably installed inside the moving cavity, a wedge block is arranged on the left side of the limiting rod and is integrally formed with the wedge block, a spring is fixedly installed on one side of the inner wall of the moving cavity away from the second support plate, and the other end of the spring is fixedly connected to the limiting rod.

[0011] In a preferred embodiment, a travel residual ring is slidably sleeved on the surface of the second support plate. A travel groove is formed inside the travel residual ring. A travel plate is fixedly installed on the surface of the second support plate. The travel plate penetrates into the travel groove. A telescopic rod is installed at the bottom of the second support plate. A stable bracket is fixedly installed at the bottom of the travel residual ring.

[0014] A road planning and surveying method for a road planning and surveying device applicable to the above includes the following steps: S1: Centering of the device; By rotating and sliding the centering rod, the centering cone can be conveniently aligned with the preset marking point. Since the central axes of the light-transmitting hole, the reflecting cone, and the centering cone are the same in the vertical direction, the light-transmitting hole is also aligned with the preset marking point at this time. When the staff fine-tunes the device, since the top of the centering cylinder is provided with a paint that can absorb light, the laser is absorbed when it irradiates on the paint and is amplified when it irradiates on the reflecting cone through the light-transmitting hole, so that the staff can easily observe that the centering is completed; S2: Stabilization of the device; By driving the screw rod to rotate, and through the cooperation of the two limit rods, the limiting rod, and the wedge block, one end of the rotating rod slides on the inner wall of the sliding groove. After the rotating rod is in the unfolded state, it drives the second support plate and the travel residual ring to descend. Taking this as the driving force, the gear is driven to descend. Through the cooperation of the tooth grooves, the stable legs adapt to the uneven ground, and at the same time, through the cooperation of the telescopic rod, the bottom plate drives the rollers to rise, isolating the rolling friction between the rollers and the ground that makes it easier for the device to move; S3: Positioning of the device. As the bottom plate rises, the cross plate drives the first drive shaft to squeeze the first drive groove. Due to the mirror image setting of the first drive groove and the second drive groove, the connecting rod drives the spline shaft and the drill bit to move downward. At the same time, due to the setting of the thread groove on the surface of the spline sleeve, the spline sleeve drives the spline shaft to rotate.

[0015] A road planning and surveying device provided by the present invention has the following beneficial effects: 1. By setting the centering mechanism, through the way of rotating the centering rod and sliding the centering rod, the centering cone and the centering control point are accurately aligned. When the lowering frame moves downward, it drives the centering rod to move downward, so that the centering cone pierces into the centering control point, further determining the accurate alignment of the centering cone and the centering control point. The staff adjusts the position of the device until the staff aligns the laser with the light-transmitting hole. The laser irradiates the reflecting cone through the light-transmitting hole, enhancing the illumination of the laser and making the centering cylinder light up, so that the staff can conveniently identify that the device has been aligned with the centering control point.

[0016] 2. By setting the stabilizing mechanism, the gear moves downward, driving the two stabilizing legs to move downward together. When the ground is uneven, one of the stabilizing legs touches the ground first and cannot continue to move downward. After the gear continues to move downward, the relative position between the gear and the stabilizing leg that touches the ground changes, causing the gear to drive the other stabilizing leg to continue to descend until the other stabilizing leg also touches the ground, so that the device can be stably supported even when facing uneven ground.

[0017] 3. By setting the positioning mechanism, when the bottom plate moves upward, the spline sleeve drives the spline shaft to rotate. At the same time, the bottom plate drives the cross plate to move upward, causing the second drive shaft to drive the connecting rod to move downward. Through the cooperation of the limiting groove and the second annular groove, the connecting rod and the spline shaft cannot move up and down relative to each other, so that the connecting rod drives the spline shaft and the drill bit to move downward and rotate into the ground, further improving the stability of the device during use and eliminating the need for an additional power source for the drill bit.

Specific implementation manners

[0032] To make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figures 1-12, the present invention provides a technical solution: a road planning and surveying device, including a bottom plate 1, a first support plate 2, a second support plate 3, a first annular groove 604 and a third support plate 4. A roller 5 is installed at the bottom of the bottom plate 1. The centering mechanism includes a lowering frame 601, a lowering groove 602, a centering rod 603, a centering cone 605, a centering cylinder 606, a reflective cone 607 and a light-transmitting hole 608. The lowering frame 601 is arranged at the bottom of the bottom plate 1. The lowering groove 602 is opened at the top of the lowering frame 601 and penetrates to the bottom of the lowering frame 601. The centering rod 603 is slidably installed inside the lowering groove 602. A first annular groove 604 adapted to the lowering groove 602 is opened on the surface of the centering rod 603. The centering cone 605 is fixedly installed at the bottom of the centering rod 603. The position of the centering cone 605 is eccentrically arranged relative to the centering rod 603. The centering cylinder 606 is fixedly installed at the top of the centering rod 603. The material of the centering cylinder 606 is a light-transmitting material. The reflective cone 607 is fixedly installed in the inner cavity of the centering cylinder 606. The light-transmitting hole 608 is opened on the top wall of the centering cylinder 606. The central axes of the light-transmitting hole 608, the reflective cone 607 and the centering cone 605 are aligned in the vertical direction.

[0034] Referring to Figures 1-12 , the stabilizing mechanism is arranged inside the first support plate 2 for stabilizing the first support plate 2. The positioning mechanism is arranged inside the bottom plate 1 for positioning the first support plate 2. By setting the centering mechanism, after the staff moves the device to the preset position and roughly aligns it with the centering control point, then by rotating the centering rod 603 and sliding the centering rod 603, the centering cone 605 and the centering control point are precisely aligned. When the lowering frame 601 moves downward, through the cooperation of the lowering groove 602 and the first annular groove 604, the lowering frame 601 limits the centering rod 603, so that the centering rod 603 cannot move up and down relative to the lowering frame 601. Thus, the lowering frame 601 drives the centering rod 603 to move downward, so that the centering cone 605 is inserted into the centering control point, further determining the precise alignment of the centering cone 605 and the centering control point. The staff starts the laser on the device and then adjusts the position of the device. Since the top of the centering cylinder 606 is coated with a paint that can absorb light, the laser cannot shine into the inside of the centering cylinder 606 when it shines on the paint until the staff aligns the laser with the light-transmitting hole 608. Since the central axes of the light-transmitting hole 608, the reflective cone 607 and the centering cone 605 are aligned in the vertical direction, the laser shines on the reflective cone 607 through the light-transmitting hole 608, strengthening the illumination of the laser and making the centering cylinder 606 light up. Thus, the staff can conveniently identify that the device has been aligned with the centering control point.

[0035] Referring to Figures 1-12, the stabilizing mechanism includes a stabilizing groove 701, stabilizing legs 702, a tooth groove 703, and a gear 704. The stabilizing groove 701 is opened at the bottom of the first support plate 2, and the opposite sides of the inner wall of the stabilizing groove 701 are respectively slidably installed with stabilizing legs 702. The tooth groove 703 is opened on the opposite sides of the two stabilizing legs 702. The gear 704 is slidably arranged inside the stabilizing groove 701, and the gear 704 and the two stabilizing legs 702 are both meshed and connected through the tooth groove 703.

[0036] By setting the stabilizing mechanism, through the cooperation of the stabilizing groove 701 and the meshing connection between the gear 704 and the two stabilizing legs 702, the two stabilizing legs 702 are in a state of two-force balance, causing the gear 704 to move downward, driving the two stabilizing legs 702 to move downward together. When the ground is uneven, one of the stabilizing legs 702 first touches the ground, and this stabilizing leg 702 cannot continue to move downward. After the gear 704 continues to move downward, the relative position between the gear 704 and the stabilizing leg 702 that touches the ground changes, causing the gear 704 to drive the other stabilizing leg 702 to continue to descend until the other stabilizing leg 702 also touches the ground. Thus, the device can be stably supported when facing uneven ground, preventing the device from collapsing or shaking and affecting the surveying and mapping accuracy.

[0037] Refer to Figures 1-12 , the positioning mechanism includes a spline sleeve 801, a threaded groove 802, a connecting rod 803, a limiting groove 804, a spline shaft 805, a drill bit 806, and a second annular groove 807. The spline sleeve 801 is sleeved inside the bottom plate 1, and a threaded groove 802 is opened on the surface of the spline sleeve 801. The spline sleeve 801 is threadedly connected to the bottom plate 1 through the threaded groove 802. The connecting rod 803 is fixedly installed on the surface of the descending frame 601, and a limiting groove 804 is opened at the top of the connecting rod 803. The spline shaft 805 is slidably sleeved inside the spline sleeve 801. A drill bit 806 is installed at the bottom of the spline shaft 805. A second annular groove 807 adapted to the limiting groove 804 is opened on the surface of the spline shaft 805. A power groove 34 is opened inside the first support plate 2, and a power plate 35 is slidably installed inside the power groove 34. A first driving groove 36 and a second driving groove 37 are opened on the surface of the power plate 35. The first driving groove 36 and the second driving groove 37 are mirror-symmetrically arranged. Transverse plates 38 are fixedly installed on both the left and right sides of the bottom plate 1. A first driving shaft is installed on the side of the transverse plate 38 close to the power plate 35. The first driving shaft is slidably sleeved inside the first driving groove 36. A second driving shaft is installed at one end of the connecting rod 803. The second driving shaft is slidably sleeved inside the second driving groove 37.

[0038] By setting the positioning mechanism, since the bottom plate 1 and the spline sleeve 801 are threadedly connected through the thread groove 802, and a connecting frame is fixedly installed at the top of the first support plate 2, the top of the spline sleeve 801 is rotatably connected to the bottom of the connecting frame. When the bottom plate 1 moves upward, the spline sleeve 801 drives the spline shaft 805 to rotate. At the same time, the bottom plate 1 drives the cross plate 38 to move upward, driving the first drive shaft to squeeze the inner wall of the first drive groove 36, causing the power plate 35 to move along the direction of the power groove 34. Since the first drive groove 36 and the second drive groove 37 are mirror-symmetrically arranged, when the power plate 35 moves, the inner wall of the second drive groove 37 squeezes the second drive shaft, causing the second drive shaft to drive the connecting rod 803 to move downward. Through the cooperation of the limit groove 804 and the second annular groove 807, the connecting rod 803 and the spline shaft 805 cannot move up and down relative to each other, so that the connecting rod 803 drives the spline shaft 805 and the drill bit 806 to move downward and rotate and drill into the ground, thereby further improving the stability of the equipment during use and eliminating the need to provide an additional power source for the drill bit 806.

[0039] Refer to Figures 1-12 , a lead screw 9 is rotatably installed between the first support plate 2 and the third support plate 4, a limit rod 10 is fixedly installed between the first support plate 2 and the third support plate 4, and drive plates 11 are sleeved on the surfaces of the lead screw 9 and the limit rod 10. Moreover, the lead screw 9 is threadedly connected to one of the drive plates 11. A drive sleeve 12 is fixedly installed between the two drive plates 11. A rotating groove 13 is formed on the surface of the drive sleeve 12. A sliding groove 14 is formed at the top of the second support plate 3. A guiding groove 15 is formed on the inner wall of the sliding groove 14. A guiding shaft 16 is slidably installed inside the guiding groove 15. A rotating rod 17 is rotatably installed on the surface of the guiding shaft 16. The other end of the rotating rod 17 is rotatably connected to the rotating groove 13. A positioning support 18 is fixedly installed on the side of the rotating rod 17 close to the centering cylinder 606. By setting the drive sleeve 12 and the rotating rod 17, a motor is installed at the bottom of the third support plate 4, and the output end of the motor drives the lead screw 9 to rotate through a transmission belt. This is a prior art and will not be elaborated here. Moreover, a through hole is formed on the surface of the second support plate 3, and the lead screw 9 and the limit rod 10 are both sleeved inside the through hole and have no contact with the second support plate 3. After the lead screw 9 rotates, due to the threaded connection between the lead screw 9 and one of the drive plates 11 and the cooperation between the limit rod 10 and the wedge block 22, one end of the rotating rod 17 rotates inside the rotating groove 13, and the other end of the rotating rod 17 slides inside the sliding groove 14, causing the rotating rod 17 to be in an unfolded state to enhance the support effect. After the rotating rod 17 reaches the preset position, the drive sleeve 12 drives the rotating rod 17 to move downward. After the positioning support 18 unfolds and moves downward along with the rotating rod 17, the limiting effect on the centering cylinder 606 is lost, enabling the staff to adjust the position of the centering cylinder 606. On the contrary, after the rotating rod 17 returns to the initial position, the positioning support 18 limits the centering cylinder 606 to prevent the centering cylinder 606 from being damaged due to shaking when the equipment moves.

[0040] Referring to Figures 1-12 , an attachment rod 19 is fixedly installed on the surface of the first support plate 2. A moving cavity 20 is formed on the side of the attachment rod 19 close to the second support plate 3. A limiting rod 21 is slidably installed inside the moving cavity 20. A wedge block 22 is arranged on the left side of the limiting rod 21 and is integrally formed with the wedge block 22. A spring 23 is fixedly installed on the side of the inner wall of the moving cavity 20 away from the second support plate 3. The other end of the spring 23 is fixedly connected to the limiting rod 21. By providing the attachment rod 19 and the limiting rod 21, when the screw rod 9 is rotated to drive the driving plate 11 to drive the driving sleeve 12 to move downward, at this time, due to the limitation of the wedge block 22, the driving sleeve 12 cannot directly drive the rotating rod 17 and the second support plate 3 to move downward. After the rotating rod 17 slides and unfolds inside the sliding groove 14, it presses against the upper end of the limiting rod 21, causing the limiting rod 21 to drive the wedge block 22 to move away from the rotating rod 17, so that the wedge block 22 retracts into the moving cavity 20. At this time, without the limitation of the wedge block 22, the driving sleeve 12 drives the second support plate 3 to move downward through the rotating rod 17.

[0041] Referring to Figures 1-12 , a travel residual ring 24 is slidably sleeved on the surface of the second support plate 3. A travel groove 25 is formed inside the travel residual ring 24. A travel plate 26 is fixedly installed on the surface of the second support plate 3. The travel plate 26 penetrates into the travel groove 25. A telescopic rod 27 is installed at the bottom of the second support plate 3. A stable support 28 is fixedly installed at the bottom of the travel residual ring 24. A gear 704 is rotatably sleeved on the bottom of the stable support 28. By providing the travel residual ring 24, the travel groove 25 and the travel plate 26, when the second support plate 3 moves downward, it drives the travel residual ring 24 to move downward. Through the cooperation of the stable support 28, it drives the gear 704 to move downward, thereby driving the stable mechanism to operate. When one of the stable legs 702 touches the ground, at this time, this group of stable legs 702 and the travel residual ring 24 can no longer descend, causing the second support plate 3 to drive the travel plate 26 to slide inside the travel groove 25, so that the second support plate 3 can continue to move downward. Moreover, a stable spring is installed between the bottom of the travel plate 26 and the bottom of the inner wall of the travel groove 25. When the second support plate 3 continues to move downward, it applies a squeezing force to the stable legs 702 that have touched the ground and stabilized through the stable spring until the remaining stable legs 702 all come into contact with and fit the ground.

[0042] It should be noted that the travel residual ring 24, the travel groove 25, the travel plate 26 and the stable mechanism can be correspondingly provided in multiple numbers. Through the mutual cooperation of the travel groove 25 and the travel plate 26, when one of the stable legs 702 fits with the ground and cannot move, the second support plate 3 can continue to descend to drive the normal operation of the remaining groups of stable mechanisms.

[0043] Referring to Figures 1-12, a lifting groove 29 is formed at the top of the bottom plate 1. A lifting plate 30 is slidably installed inside the lifting groove 29. The top of the lifting plate 30 is connected to the other end of the telescopic rod 27. A first deflection groove 31 is formed on the inner wall of the lifting groove 29, and a second deflection groove 32 is formed on the surface of the lifting plate 30. One end of the first deflection groove 31 coincides with one end of the second deflection groove 32, and a deflection shaft 33 is slidably sleeved between the first deflection groove 31 and the second deflection groove 32. By providing the lifting plate 30 and the lifting groove 29, when the second support plate 3 moves downward, the telescopic rod 27 contracts until the telescopic rod 27 finishes contracting. Then, the second support plate 3 drives the telescopic rod 27 to squeeze the lifting plate 30, causing the lifting plate 30 to move downward. The inner wall of the second deflection groove 32 squeezes the deflection shaft 33. After the deflection shaft 33 moves, it squeezes the inner wall of the first deflection groove 31, causing the bottom plate 1 to drive the roller 5 to move upward, so that the roller 5 is not in contact with the ground, isolating the rolling friction between the roller 5 and the ground, which makes it easier for the device to move.

[0044] A surveying and mapping method for road planning, applicable to the above-mentioned surveying and mapping device for road planning, includes the following steps: S1: Centering of the device; By rotating and sliding the centering rod 603, the centering cone 605 can be conveniently aligned with the preset marking point. Since the central axes of the light-transmitting hole 608, the reflecting cone 607, and the centering cone 605 are the same in the vertical direction, the light-transmitting hole 608 is also aligned with the preset marking point at this time. When the staff fine-tunes the device, since the top of the centering cylinder 606 is provided with a paint that can absorb light, the laser is absorbed when it irradiates on the paint. When it irradiates on the reflecting cone 607 through the light-transmitting hole 608, the light is amplified, and the staff can easily observe that the centering is completed. S2: Stabilization of the device; By driving the screw rod 9 to rotate, and through the cooperation of the two limiting rods 10, the limiting rod 21, and the wedge block 22, one end of the rotating rod 17 slides on the inner wall of the sliding groove 14. After the rotating rod 17 is in the unfolded state, it drives the second support plate 3 and the stroke residual ring 24 to descend. Taking this as the driving force, it drives the gear 704 to descend.
