Description

Technical Field

[0001] The present invention relates to the technical field of road engineering, and in particular to an adjustable measuring device suitable for surveying and mapping various road engineering environments and a use method thereof. Background Art

[0002] Road engineering is an important branch of civil engineering, involving road planning, design, construction, maintenance and management. Road engineering environmental mapping is an important part of road planning, design and early construction. Through high-precision geographic information collection and analysis, it ensures the coordination between the project and the natural environment, avoids ecological risks and optimizes route selection. In the process of road engineering surveying and mapping, various special equipment for topographic surveying and mapping are used, including total stations, three-dimensional laser scanners, levels, rangefinders, etc., and these measuring devices are installed and used by tripods. For example, the existing public document CN118049588A-Outdoor surveying and measuring device suitable for multi-topographic environments, the existing public document CN115325365A-A surveying and mapping device for road planning and design, and the existing public document CN117053776B-A surveying and mapping device for urban and rural road planning disclose a road surveying and mapping device; Although the existing adjustable measuring devices suitable for various road engineering environment surveying and mapping can realize the measurement operation, there are still certain shortcomings in actual use: First, during the centering process of the existing adjustable measuring devices suitable for various road engineering environment surveying and mapping, the operator needs to adjust the position of the two tripods of the tripod to align the laser point with the engineering control point. This method requires the operator to control the operating legs with stable hands, which will increase the operator's energy consumption and work intensity during operation. At the same time, if the working environment is poor (such as soft soil texture, uneven ground), the applicability is poor, which will increase the working time and reduce efficiency. rate; secondly, when the existing adjustable measuring device suitable for various road engineering environment surveying and mapping adjusts the circular bubble in the rough level of the instrument, it is necessary to manually control the sliding height of the tripod legs, so the stability of the manual hands is required to be high. In the actual operation process, the operator's hand strength decreases, which will affect the adjustment stability, increase the time consumption of the rough level adjustment, and reduce the adjustment quality; finally, when the existing adjustable measuring device suitable for various road engineering environment surveying and mapping is centered in a strong light environment, it is difficult for the operator to clearly observe the position of the laser point, which affects the efficiency of the equipment centering; therefore, it is necessary to improve the existing technology to solve the above technical problems.

[0034] Example 1 Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6, which is the first embodiment of the present invention, provides an adjustable measuring device suitable for various road engineering environment surveying and mapping. The adjustable measuring device suitable for various road engineering environment surveying and mapping can quickly adjust the position of the tripod through translation and sliding, thereby reducing the operator's mental consumption and work intensity, and has high work efficiency.

[0035] Specifically, a triangular seat 100, a hollow hole 101 is provided in the middle of the triangular seat 100; a surveying and mapping instrument body 200, the base of the surveying and mapping instrument body 200 is fixedly connected to the triangular seat 100 by connecting bolts; a tripod rotating section 300, a tripod extension section 302 is slidably installed inside the tripod rotating section 300, the outer wall of the triangular seat 100 is rotatably installed with the tripod rotating sections 300 at uniform intervals along the circumferential direction of the inner wall of the hollow hole 101, and a tripod fine-tuning section 303 is slidably installed inside the tripod extension section 302; a base frame 500, stabilizing nails 501 are fixed at uniform intervals on the bottom of the base frame 500, and sliding holes 502 are provided on the upper sides of the two side walls of the base frame 500; and an adjustment component 600, including a first sprocket 601 rotatably installed on the rear end of the outer wall of the base frame 500 and a second sprocket 602 symmetrically arranged in front of the first sprocket 601.

[0036] For details, please refer to Figure 6 and Figure 7 A chain 603 is sleeved on the outer wall of the first sprocket 601 and the second sprocket 602, a pedal 604 is arranged on the outer side of the chain 603, and the second sprocket 602 is rotatably mounted on the outer wall of the bottom frame 500; a connecting rod 604a is fixedly arranged at the front and rear ends of one side wall of the pedal 604, and a pressing block 605 is fixedly arranged at the other end of the connecting rod 604a, and the bottom center position of the pressing block 605 is connected to the telescopic end of the telescopic rod 606 by bolts, and the bottom end of the telescopic rod 606 is mounted on the surface of the supporting plate 607 by bolts; a first spring 606a is sleeved on the outer wall of the telescopic rod 606 , one end of the pressing block 605 is movably connected to the claw 608 through a hinge, a second rotating shaft 608a is fixedly provided in the middle of a side wall of the claw 608, and the end of the claw 608 is clamped in the tooth groove of the outer wall of the adjacent first sprocket 601 and the second sprocket 602; wherein, one side wall of the pressing block 605 is slidably connected to the outer wall of the base frame 500, one side wall of the supporting plate 607 is installed on the outer wall of the base frame 500 by bolts, the telescopic rod 606 and the first spring 606a are both located between the pressing block 605 and the supporting plate 607, and the second rotating shaft 608a is rotatably installed on the outer wall of the base frame 500; When the above arrangement is used, the operator rotates the three sets of tripod rotating sections 300 on the outside of the tripod to a certain angle and supports them on the road surface. Then, the operator adjusts the angle of the base frame 500 through the first rotating shaft 304a so that the base frame 500 fits well with the soil surface and maintains stability. The operator also uses the locking bolt 301a to adjust the length of the tripod extension section 302 so that the height of the tripod 100 is adjusted to the chest position of the operator. Then, the surveying and mapping instrument body 200 is installed on the surface of the tripod 100 by bolts. After the surveying and mapping instrument body 200 is installed, It is necessary to align the laser point on the surveying instrument body 200 with the engineering control point of the surveying position. At this time, it is necessary to adjust the position of the tripod. First, step on the base frame 500 on one set of the tripods to insert the stabilizing nail 501 at the bottom of the base frame 500 into the road soil. Then, step on the pedals 604 at the bottom of the other two tripods in turn. The pedals 604 are forced to drive the pressure blocks 605 at both ends to move downward under the action of the connecting rod 604a. The downward movement of the pressure blocks 605 will squeeze the telescopic rod 606 and the first spring 606a. The ends of the pressure blocks 605 are movable through the hinges and the claws 608. The claw 608 is rotatably connected to the outer wall of the base frame 500 under the action of the second rotating shaft 608a. At this time, the claw 608 rotates with the second rotating shaft 608a as the center and moves out of the tooth grooves of the adjacent first sprocket 601 and the second sprocket 602. Then the operator can apply force to the tripod so that the tripod slides and quickly adjusts its position under the action of the first moving block 305, the second moving block 306 and the sliding hole 502. By changing the position of the two sets of tripods, the position of the laser point emitted by the surveying and mapping instrument body 200 is changed, and the laser point is aligned with the engineering control point. Therefore, when centering, it is only necessary to translate and adjust the two tripods away from the laser point relative to the engineering control point, without manually lifting and adjusting the position of the tripods, which reduces the energy consumption and work intensity of the operators. At the same time, it is more suitable for various engineering environments and improves work efficiency. After the laser point and the engineering control point are aligned, stop applying force to the pedal 604. At this time, the pressure block 605 is rebounded under the elastic action of the first spring 606a, so that the claw 608 returns to the initial position and is stuck in the tooth groove on the outer wall of the first sprocket 601 and the second sprocket 602, which plays a role of limiting.

[0037] Furthermore, the tripod 100 and the surveying and mapping instrument body 200 are both prior arts, so they will not be described in detail here. The tripod as a whole includes a tripod rotating section 300, a tripod extension section 302 and a tripod fine-tuning section 303. The tripod extension section 302 can slide and adjust its position inside the tripod rotating section 300, and the tripod fine-tuning section 303 can slide and adjust its position inside the tripod extension section 302. The tripod rotating section 300 and the tripod 100 can be rotated to adjust the angle. The stabilizing nail 501 is used to improve the stability of the bottom end of the tripod. The chain 603 can rotate with the assistance of the first sprocket 601 and the second sprocket 602. The pressure block 605 and the pedal 604 are connected by the connecting rod 604a to play a role of connecting transmission. The telescopic rod 606 limits the first spring 606a, and can drive the pressure block 605 to move under the elastic action of the first spring 606a. The claw 608 rotates with the second rotating shaft 608a as the center when subjected to force.

[0038] Read in detail Figure 3 , Figure 4 and Figure 5 As shown, a sleeve frame 301 is sleeved on the bottom end of the outer wall of the tripod rotating section 300, a locking bolt 301a is screwed on the bottom end of one side wall of the sleeve frame 301, a bottom block 303a is fixedly provided at the bottom end of the tripod fine-tuning section 303, a rotating plate 304 is fixedly provided at the bottom of the bottom block 303a, and a first rotating shaft 304a is fixedly provided on the inner wall of the rotating plate 304; both ends of the first rotating shaft 304a are rotatably mounted in bearings on the end faces of the adjacent first moving block 305 and the second moving block 306, respectively, and a tooth plate 306a is fixedly provided on the outer wall of the second moving block 306; wherein, the rack at the bottom of the tooth plate 306a is clamped in the hole groove of the chain 603, and the first moving block 305 and the second moving block 306 are slidably mounted inside the adjacent sliding holes 502.

[0039] Furthermore, the position of the tripod extension section 302 is adjusted by the locking bolt 301a, and the angle of the base frame 500 can be adjusted under the action of the first rotating shaft 304a, so that the bottom of the base frame 500 is close to the ground, and the first moving block 305 and the second moving block 306 slide in translation inside the sliding hole 502, and the tooth plate 306a is clamped in the empty groove on the chain 603, which serves the purpose of limiting synchronous movement.

[0040] Example 2 Reference Figure 4 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference is that in order to fine-tune the height of the tripod, force is applied to the knob 400. Due to the spiral fit between the screw rod 401 and the threaded hole on the tripod extension section 302, the purpose of macro adjustment of the tripod fine-tuning section 303 is achieved, thereby accelerating the rough leveling time of the surveying and mapping instrument body 200.

[0041] Specifically, it also includes a knob 400 disposed above the tripod extension section 302, a screw rod 401 is fixed at the bottom center of the knob 400, and the other end of the screw rod 401 is spirally penetrated through the threaded hole on the tripod extension section 302 and is rotatably connected to the top of the tripod fine-tuning section 303; When the above arrangement is in use, after the operator aligns the laser point on the surveying and mapping instrument body 200 with the engineering control point, it is necessary to perform leveling operations through the circular bubble on the surveying and mapping instrument body 200. When setting the height of the tripod 100, corresponding adjustments are mainly made through the tripod rotating section 300 and the tripod extension section 302. During the rough leveling process of the surveying and mapping instrument body 200, it is necessary to finely adjust the height of each tripod. At this time, the operator can apply force to the knob 400 in the tripod near the circular bubble position, and the knob 400 is driven by the force to drive the screw 401 to rotate, and the screw 401 is spirally matched with the threaded hole on the tripod extension section 302. Therefore, when the screw 401 rotates, it can drive the tripod fine-tuning section 303 to slide along the inner wall of the tripod extension section 302 to adjust the height, thereby quickly adjusting the height of the tripod. In this process, the operator does not need to manually hold and control the adjustment of the tripod, which can improve the stability and quality of the tripod height adjustment and reduce the time consumed in rough leveling adjustments.

[0042] Furthermore, the external thread on the outer wall of the screw rod 401 and the internal thread in the wall of the threaded hole on the tripod extension section 302 are screwed together to achieve position adjustment of the tripod fine-tuning section 303 .

[0043] Example 3 Reference Figure 3 , Figure 8 and Fig. 9 , which is the third embodiment of the present invention, is based on embodiment 1, and the difference is that, in order to reduce the influence of ambient light, after the three sets of surrounding tripods are opened, the gas flow between the air bag 702 and the air cylinder 704 is utilized to make the folding blackout curtain 709 unfold, thereby playing a role of shading.

[0044] Specifically, it also includes a shading component 700 arranged directly below the triangular seat 100, the shading component 700 includes a triangular frame 701 installed at the bottom of the triangular seat 100 through a connecting plate and an air bag 702 embedded in the triangular frame 701, and a triangular plate 703 is arranged on the top of the air bag 702; convex plates 703a are fixed on both sides of the three sides of the triangular plate 703, the bottom of the three sides of the outer wall of the triangular frame 701 are movably connected to the air cylinder 704 through hinges, the telescopic end of the air cylinder 704 is movably connected to the sleeve frame 301 through a hinge, and the convex plate 703a is fixed on the bottom of the triangular plate 703; A guide rod 705 is fixedly arranged at the bottom; a second spring 706 is sleeved on the outer wall of the guide rod 705, the bottom end of the guide rod 705 passes through the through hole on the fixing seat 707 and is connected to the pull plate 708, and a folding blackout curtain 709 is arranged on the inner wall of the pull plate 708; wherein the air bag 702 is connected to the air cylinder 704 through a pipeline, the second spring 706 is located between the convex plate 703a and the fixing seat 707, the outer wall of the fixing seat 707 is fixedly connected to the outer wall of the triangular frame 701 by bolts, and the top end of the folding blackout curtain 709 is fixedly arranged at the bottom of the triangular frame 701; When the above arrangement is in use, when the operator unfolds the three sets of tripods outside the triangular seat 100, the sleeve frame 301 rotates outward with the tripod rotating section 300 to open, and the inner wall of the sleeve frame 301 is movably connected to the gas cylinder 704 through a hinge, and the inner end of the gas cylinder 704 is movably connected to the outer wall of the triangular frame 701 through a hinge, so when the sleeve frame 301 moves outward, the gas cylinder 704 will be pulled to extend, wherein the gas cylinder 704 and the airbag 702 are connected through a pipeline, so after the gas cylinder 704 is extended, the air in the airbag 702 will be extracted through the pipeline, and the gas volume inside the airbag 702 is reduced, so that the triangular plate 703 on the top thereof moves downward, and the triangular plate 703 on the top thereof moves downward. After the plate 703 moves down, it drives multiple groups of convex plates 703a to descend synchronously, and the descent of the convex plate 703a will push the pull plate 708 down under the action of the guide rod 705 and squeeze the second spring 706. At the same time, when the pull plate 708 descends, the folding blackout curtain 709 will be unfolded. After the folding blackout curtain 709 is unfolded, it can block the external ambient light, so that when the operator is aligning the laser point with the engineering control point, it can play a role of shading, reduce the influence of external ambient light, and enable the operator to better observe the position of the laser point and the engineering control point, improve the centering efficiency, and make the device suitable for strong light environment, thereby improving the scope of application.

[0045] Furthermore, the bottom of the airbag 702 is fixed to the bottom of the triangular frame 701, and only the top of the airbag 702 can be raised and lowered, so that the triangular plate 703 moves synchronously with it, and the convex plate 703a and the pull plate 708 are connected by the guide rod 705, which plays a role in connecting transmission. Under the elastic action of the second spring 706, the pull plate 708 can be quickly retracted to the top, and the contraction of the folding blackout curtain 709 can be realized.

[0046] Example 4 This embodiment is the fourth embodiment of the present invention, which provides a method for using an adjustable measuring device suitable for various road engineering environment surveying and mapping, specifically, including the following steps: S1: First, the operator rotates the tripod outside the triangular seat 100 to support it on the road surface. During the process of the three sets of tripods being opened, the air cylinder 704 and the air bag 702 are connected by a pipeline. When the air cylinder 704 is stretched, the folding sunshade curtain 709 is unfolded to block the ambient light. S2: After the three sets of tripods are spread out, the surveying and mapping instrument body 200 is then installed on the surface of the tripod 100, and the laser point on the surveying and mapping instrument body 200 is aligned with the engineering control point to achieve the centering operation; S3: Then the operator steps on the base frame 500 on the tripod near the laser point position to insert the stabilizing nail 501 at the bottom of the base frame 500 into the soil, and then steps on the pedal 604 and moves the other two sets of tripods until the laser point is aligned with the engineering control point; S4: Finally, the operator applies force to the knob 400 to drive the screw 401 to rotate, and the height position of the tripod fine-tuning section 303 is adjusted under the spiral cooperation between the screw 401 and the threaded hole on the tripod extension section 302, so as to achieve the purpose of adjusting the position of the circular bubble; S5: Repeat the above operation to adjust the positions of the multiple sets of tripod fine-tuning sections 303 until the rough leveling operation of the surveying and mapping instrument body 200 is completed.
