Description

Technical Field

[0001] This invention relates to the field of settlement detection technology, and in particular to an adjustable measuring instrument suitable for comprehensive land and space management. Background Technology

[0002] Land surveying is the work of measuring and mapping the quantity, distribution, topographic features, and other characteristics of various types of land using surveying and remote sensing techniques. It includes topographic surveying and surface subsidence surveying. Roadbed surface settlement refers to the subsidence of the road surface or roadbed soil due to various factors. Usually, the road surface or roadbed has undergone vertical displacement relative to its original position. Existing roadbed settlement devices generally place a scale and measuring components on the roadbed. When the roadbed settles, the scale moves up and down with the roadbed while the measuring components remain stationary, or the measuring components move up and down with the roadbed while the scale remains stationary, and the measuring components and scale are displaced. The settlement of the roadbed is determined by the reading on the scale.

[0003] While current adjustable measuring instruments for comprehensive land and space remediation can detect roadbed surface settlement, they only have the function of detecting single points. Without multi-point detection, the test results will not be representative, leading to inaccurate detection of roadbed surface settlement and reducing the effectiveness of the detection. Therefore, there is an urgent need to design an adjustable measuring instrument suitable for comprehensive land and space remediation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose an adjustable measuring instrument suitable for comprehensive land space management.

A groove is provided at the bottom of the crossbeam, and a slider fixedly installed on the top of the horizontal plate slides inside the groove. A spring rod is vertically fixed at the center of the bottom of the horizontal plate. The fixed end and the telescopic end of the spring rod are slidably connected by a spline, and a conical detection disc is fixedly installed at the end of the spring rod. Translation assembly, which is mounted on the cross plate, cross beam and spring rod, and is used to perform multi-point translation detection on the conical detection disk; A marking component is provided on the spring rod and the crossbeam, and the marking component is used to mark the movement trajectory of the conical detection disk. The compaction component is mounted on the spring rod, translation component, and crossbeam, and is used to compact the soil on the surface of the roadbed to be moved by the conical detection disc.

[0006] As a further technical solution of the present invention, the translation component includes: a rack, which is vertically fixedly installed on the surface of the telescopic end of the spring rod, and a second limiting plate is fixedly installed at the bottom of the horizontal plate. The second limiting plate is L-shaped, and a first gear is rotatably installed at the horizontal end of the second limiting plate. When the first gear and the rack are in contact, the first gear and the rack mesh.

[0007] As a further technical solution of the present invention, a third limiting plate is also vertically fixedly installed at the bottom of the cross plate, a rotating rod is horizontally rotatably installed at the end of the side of the third limiting plate, and a second gear is fixedly installed at the top of the rotating rod. A toothed plate is horizontally fixedly installed at the bottom of the cross beam, and the toothed plate and the second gear mesh.

[0008] As a further technical solution of the present invention, a one-way bearing is sleeved on the surface of the rotating rod, and a small pulley is fixedly sleeved on the outer ring of the one-way bearing. A large pulley is fixedly installed on the side of the first gear, and a second belt is sleeved on the surface of the small pulley and the large pulley.

[0009] As a further technical solution of the present invention, a torsion spring is sleeved on the surface of the rotating rod, and the two ends of the torsion spring are fixedly installed on the side of the third limiting plate and the end face of the small pulley.

[0010] As a further technical solution of the present invention, the marking component includes: a side plate, which is horizontally fixedly installed at the bottom of the crossbeam, and a horizontally arranged paper tape is attached to the bottom inner side of the side plate by Velcro.

[0011] As a further technical solution of the present invention, a three-jaw chuck is fixedly installed on the surface of the telescopic end of the spring rod, and a marker pen is horizontally fixed on the three-jaw chuck, with the end of the marker pen in contact with the side of the paper tape.

[0012] As a further technical solution of the present invention, the solidifying component includes: a sleeve plate, the end of which is slidably sleeved onto the surface of the telescopic end of the spring rod via a spline, and a leveling block is fixedly installed at the bottom of the sleeve plate; a first spring is sleeved onto the surface of the telescopic end of the spring rod, and the two ends of the first spring are respectively fixedly installed at the top of the conical detection disc and the bottom of the sleeve plate.

[0013] As a further technical solution of the present invention, a first limiting plate is vertically fixedly installed at the bottom of the horizontal plate, and an eccentric wheel is rotatably installed at the end of the side of the first limiting plate. A first pulley is fixedly installed at the center of the eccentric wheel and the center of the end face of the second gear, and a first belt is sleeved on the surface of the two first pulleys.

[0014] The beneficial effects of this invention are as follows: Firstly, this invention, through the setting of translation components, marking components, and compaction components, can simultaneously detect multiple points when roadbed surface settlement occurs, avoiding the situation where only one point of the roadbed is detected, resulting in unrepresentative test results, thereby improving the effectiveness of the equipment. Secondly, this invention, through the arrangement of translation, marking, and compaction components, allows the marker pen to draw lines on the paper tape as it moves horizontally, enabling multi-point detection of the roadbed surface. It also clearly and intuitively displays the settlement of the roadbed surface at other locations on the paper tape. The sleeve plate moves the entire plate downwards to compact and level the area that the conical detection disc is about to pass over, preventing the conical detection disc from being affected by uneven roadbeds and causing inaccurate lines on the paper tape, thus improving the effectiveness of the equipment.

[0019] Please see the appendix Figure 1 -Appendix Figure 8 An adjustable measuring instrument suitable for comprehensive land space management includes a crossbeam 1, with brackets 2 vertically fixed at both ends of the bottom of the crossbeam 1. It also includes a cross plate 27, a spring rod 3, a translation component, a marking component, and a compaction component. The cross plate 27 is slidably mounted on the bottom of the crossbeam 1. A groove 25 is provided at the bottom of the crossbeam 1, and a slider 26 fixedly mounted on the top of the cross plate 27 slides inside the groove 25. The spring rod 3 is vertically fixed at the center of the bottom of the cross plate 27, and the fixed end and telescopic end of the spring rod 3 are connected by a spline. The sliding connection is provided, and a conical detection disk 14 is fixedly installed at the end of the spring rod 3. The translation component is set on the horizontal plate 27, the horizontal beam 1 and the spring rod 3, and the translation component is used to perform multi-point translation detection on the conical detection disk 14. The marking component is set on the spring rod 3 and the horizontal beam 1, and the marking component is used to draw lines to mark the movement trajectory of the conical detection disk 14. The compaction component is set on the spring rod 3, the translation component and the horizontal beam 1, and the compaction component is used to compact the soil on the surface of the roadbed to be moved by the conical detection disk 14. As mentioned above, by using the translation component, marking component, and compaction component, multiple points can be detected simultaneously when settlement occurs on the roadbed surface, avoiding the situation where only one point on the roadbed is detected, resulting in unrepresentative test results.

[0020] Please see the appendix Figure 1 -Appendix Figure 8In a preferred embodiment, the translation component includes: a rack 30, which is vertically fixedly mounted on the surface of the telescopic end of the spring rod 3; a second limiting plate 19, which is L-shaped, is fixedly mounted on the bottom of the horizontal plate 27, and a first gear 18 is rotatably mounted on the horizontal end of the second limiting plate 19. When the first gear 18 contacts the rack 30, the first gear 18 and the rack 30 mesh; a third limiting plate 20 is also vertically fixedly mounted on the bottom of the horizontal plate 27, and a rotating rod 2 is horizontally rotatably mounted on the side end of the third limiting plate 20. 1. A second gear 24 is fixedly installed at the top of the rotating rod 21, a toothed plate 4 is fixedly installed horizontally at the bottom of the crossbeam 1, and the toothed plate 4 meshes with the second gear 24. A one-way bearing 22 is sleeved on the surface of the rotating rod 21, and a small pulley 17 is fixedly sleeved on the outer ring of the one-way bearing 22. A large pulley 6 is fixedly installed on the side of the first gear 18, and a second belt 16 is sleeved on the surface of the small pulley 17 and the large pulley 6. A torsion spring 23 is sleeved on the surface of the rotating rod 21, and the two ends of the torsion spring 23 are fixedly installed on the side of the third limiting plate 20 and the end face of the small pulley 17. Preferably, due to the arrangement of the toothed plate 4, the second gear 24 will also move when it rotates. The movement of the second gear 24 will drive the horizontal plate 27 to move horizontally through the third limiting plate 20. The horizontal movement of the horizontal plate 27 will drive the spring rod 3 and other components on it to move horizontally.

[0021] Please see the appendix Figure 1 -Appendix Figure 6 In a preferred embodiment, the marking assembly includes: a side plate 15, which is horizontally fixedly installed at the bottom of the crossbeam 1, and a horizontally arranged paper tape 7 is attached to the bottom inner side of the side plate 15 by Velcro; a three-jaw chuck 28 is fixedly installed on the surface of the telescopic end of the spring rod 3; a marker pen 29 is horizontally fixed on the three-jaw chuck 28, and the end of the marker pen 29 contacts the side of the paper tape 7. Furthermore, the marker 29 moves horizontally to draw lines on the paper tape 7, enabling multi-point detection of the roadbed surface and clearly and intuitively showing the settlement of the roadbed surface at other locations on the paper tape 7.

[0022] Please see the appendix Figure 2 -Appendix Figure 8 In a preferred embodiment, the compaction component includes: a sleeve plate 8, the end of which is slidably sleeved onto the surface of the telescopic end of the spring rod 3 via a spline, and a leveling block 9 is fixedly installed at the bottom of the sleeve plate 8; a first spring 13 is sleeved onto the surface of the telescopic end of the spring rod 3, and the two ends of the first spring 13 are respectively fixedly installed at the top of the conical detection plate 14 and the bottom of the sleeve plate 8; a first limiting plate 5 is vertically fixedly installed at the bottom of the horizontal plate 27, and an eccentric wheel 10 is rotatably installed at the end of the side of the first limiting plate 5; a first pulley 12 is fixedly installed at the center of the eccentric wheel 10 and at the center of the end face of the second gear 24, and a first belt 11 is sleeved onto the surface of the two first pulleys 12; Preferably, the rotation of the eccentric wheel 10 will apply downward pressure to the sleeve plate 8, so that the sleeve plate 8 will drive the whole plate to move downward to compact and level the part that the conical detection disc 14 is about to pass through, thus avoiding the influence of uneven roadbed on the conical detection disc 14, which would cause the lines on the paper tape 7 to be inaccurate.

[0023] When it is necessary to detect the settlement of the roadbed surface, first install two supports 2 on both sides of the roadbed to be tested, and then install the crossbeam 1 on the two supports 2. The conical detection disc 14 will contact the roadbed surface and cause the spring rod 3 to generate elastic force. Due to the action of the spring rod 3, the conical detection disc 14 will flatten the surface of the roadbed at this part, which is used to apply pressure to the conical detection disc 14 and avoid the conical detection disc 14 compacting and lowering the soil that is uneven from the surface, causing false detection. Finally, the rack 30 is installed at a suitable position on the extension end of the spring rod 3 by bolts, and the paper tape 7 is attached to the inside of the side plate 15. When the roadbed surface settles, the elastic force generated by the spring rod 3 will cause its telescopic end, three-jaw chuck 28, marker pen 29 and conical detection disc 14 to move downwards. The downward movement of the marker pen 29 will draw a line on the paper tape 7. The movement of the telescopic end of the spring rod 3 will drive the rack 30 to move. The movement of the rack 30 will mesh with the first gear 18 and drive the first gear 18 to rotate. The rotation of the first gear 18 will drive the large pulley 6 to rotate. The rotation of the large pulley 6 will drive the small pulley 17 to rotate through the second belt 16. The rotation of the small pulley 17 will cause the torsion spring 23 to generate torque. At this time, the rotation of the small pulley 17 will not drive the rotating rod 21 to rotate through the one-way bearing 22. When the roadbed surface subsides to the maximum preset value, the rack 30 and the first gear 18 separate. The torque generated by the torsion spring 23 will cause the small pulley 17 to rotate in the opposite direction. The reverse rotation of the small pulley 17 will drive the rotating rod 21 to rotate through the one-way bearing 22. The rotation of the rotating rod 21 will drive the second gear 24 to rotate. Due to the setting of the toothed plate 4, the second gear 24 will also move when it rotates. The movement of the second gear 24 will drive the horizontal plate 27 to move horizontally through the third limiting plate 20. The horizontal movement of the horizontal plate 27 will drive the spring rod 3 and other components on it to move horizontally. The movement of the spring rod 3 will drive the conical detection disk 14 to move horizontally, thus realizing multi-point detection of the roadbed surface and ensuring the accuracy of the detection. In addition, when the spring rod 3 moves horizontally with the horizontal plate 27, it will also drive the marker pen 29 to move horizontally. The horizontal movement of the marker pen 29 will draw lines on the paper tape 7 to achieve multi-point detection of the roadbed surface and clearly and intuitively indicate the settlement of other roadbed surfaces on the paper tape 7. Furthermore, the rotation of the second gear 24 will also drive the first pulley 12 and the first belt 11 to rotate. The rotation of the first pulley 12 will drive the eccentric wheel 10 to rotate. The rotation of the eccentric wheel 10 will apply downward pressure to the sleeve plate 8, so that the sleeve plate 8 will drive the whole plate to move downward to compact and level the part that the conical detection disc 14 is about to pass through, thus avoiding the influence of uneven roadbed on the conical detection disc 14, which would cause the lines on the paper tape 7 to be inaccurate. In summary, this method allows for simultaneous detection of multiple points when roadbed surface settlement occurs, avoiding the situation where only one point on the roadbed is detected, which would result in unrepresentative test results and thus improves the effectiveness of the equipment.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
