Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, and in particular to a highly efficient and accurate on-site surveying and mapping assistant for engineering cost. Background Art

[0002] In the field of engineering cost, on-site surveying is an important basis for key links such as determining engineering quantities, formulating budgets, controlling costs and conducting construction management. Traditional surveying operations mainly rely on surveying instruments such as total stations and theodolites. In actual use, these instruments usually need to be supported by tripods for stable support to ensure the accuracy of surveying data. However, this operation process faces a series of challenges and shortcomings in actual applications.

[0003] Specifically, before each surveying and mapping task begins, selecting a suitable location and placing a tripod are basic steps. Then the staff needs to carefully take out the surveying and mapping instrument from a special box and accurately install it on the tripod. Afterwards, they need to go through tedious adjustment steps to ensure that the surveying and mapping instrument can reach the preset working height. This process is not only time-consuming, but also requires a high degree of precision. After the surveying and mapping task is completed, the same tedious steps begin again. The staff needs to carefully remove the surveying and mapping instrument from the tripod and put it back into a special box to ensure its safe storage. At the same time, The tripod is disassembled and collected for subsequent storage or carrying. These repeated loading, unloading and adjustment steps not only consume a lot of time and energy, but also increase the risks in the operation process, such as instrument damage or data errors, which seriously restricts the overall efficiency of the surveying and mapping operations. In addition, the surveying and mapping instruments and tripods are two independent components, and their storage and carrying also bring many inconveniences. The staff needs to find suitable storage space for these two components separately and be careful when carrying them to avoid collision or damage. This scattered storage and carrying method not only increases the complexity of the operation, but also reduces work efficiency. Summary of the invention

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0019] An efficient and accurate on-site engineering cost surveying and mapping assistant according to an embodiment of the present invention will be described below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 6 As shown, an efficient and accurate on-site engineering cost surveying and mapping assistant according to an embodiment of the present invention includes: The receiving cylinder 1 is provided with an observation port 11, an operation port 12 and a guide groove 13 in sequence from top to bottom along the vertical direction on the surface; The elastic metal support foot 2 is arranged in the guide groove 13, and the top end thereof penetrates into the lower end of the accommodating cylinder 1; The driving assembly 3 includes a manual driving mechanism 31, a first transmission shaft 32 and a second transmission shaft 33. The manual driving mechanism 31 is arranged in the operation port 12. One end of the first transmission shaft 32 is connected to the top of the manual driving mechanism 31. The other end of the first transmission shaft 32 penetrates into the upper end of the accommodating cylinder 1 and is connected to the surveying instrument body 10 arranged in the upper end of the accommodating cylinder 1. One end of the second transmission shaft 33 is connected to the bottom of the manual driving mechanism 31. The other end of the second transmission shaft 33 penetrates into the lower end of the accommodating cylinder 1 and is connected to the top of the elastic metal support foot 2. The elastic blocking seat 4 is arranged on the surface of one end of the first transmission shaft 32 that penetrates into the upper end of the accommodating cylinder 1 , and is used to block the observation port 11 .

[0021] It should be noted that the surveying and mapping instrument body 10 and the first transmission shaft 32 described in this embodiment are detachably connected to facilitate subsequent replacement of the surveying and mapping equipment.

[0022] It should also be noted that the surface of the containing cylinder 1 is symmetrically and slidingly connected to the limiting rope seat 200, and the inner end of the limiting rope seat 200 is magnetically fixed to the inner wall of the containing cylinder 1. When the external pulling force is greater than the magnetic attraction force, one end of the limiting rope seat 200 protrudes from the surface of the containing cylinder 1.

[0023] Specifically, the accommodating cylinder 1 is the main structure of the entire auxiliary device, which is used to store and protect the elastic metal support foot 2 and the surveying instrument body 10. The observation port 11 is located at the upper part of the accommodating cylinder 1, so that the user can directly observe the working status of the surveying instrument body 10 through the observation port 11 without opening the entire cylinder. The operation port 12 is located below the observation port 11, providing sufficient space for the user to operate the driving component 3 to adjust the state of the elastic metal support foot 2 and the height of the surveying instrument body 10. The guide groove 13 is set at the lower end of the accommodating cylinder 1 to guide and support the elastic metal support foot 2 to ensure the stable deployment and retraction of the elastic metal support foot 2. The elastic metal support foot 2 is used to provide stable support during surveying and mapping to ensure that the accommodating cylinder 1 and the surveying instrument body 10 can maintain a horizontal state. The elastic metal support foot 2 is designed to be elastic and can be easily retracted into the guide groove 13 when not in use, thereby reducing space occupancy. The top of the elastic metal support foot 2 is connected to the second transmission shaft 33, and the drive component 3 is driven to realize synchronous expansion and retraction. The user drives the entire drive system by operating the manual drive mechanism 31. The first transmission shaft 32 is connected to the surveying instrument body 10. By running the manual drive mechanism 31, the height of the surveying instrument body 10 can be adjusted. The second transmission shaft 33 is connected to the elastic metal support foot 2, which is used to synchronously control the expansion and retraction of the elastic metal support foot 2. The user drives the first transmission shaft 32 and the second transmission shaft 33 to rise and fall synchronously by operating the manual drive mechanism 31, so as to respectively realize the height adjustment of the surveying instrument body 10 and the expansion / retraction of the elastic metal support foot 2. When the surveying instrument body 10 is not in working state, the elastic blocking seat 4 will block the observation port 11 to prevent external factors such as dust and moisture from damaging the surveying instrument body 10. The elastic blocking seat 4 is designed to be elastic and can fit closely to the edge of the observation port 11 to ensure the sealing effect. The elastic blocking seat 4 is installed on the end surface of the first transmission shaft 32 that penetrates into the accommodating cylinder 1, and rises and falls synchronously with the first transmission shaft 32.

[0024] The working principle is as follows: the user operates the manual driving mechanism 31 through the operation port 12, the manual driving mechanism 31 drives the first transmission shaft 32 to rise and fall, and synchronously adjusts the height of the surveying instrument body 10. At the same time, the manual driving mechanism 31 also drives the second transmission shaft 33 to rise and fall, so that the elastic metal support foot 2 is synchronously expanded or retracted. When the surveying instrument body 10 is not in a working state, the elastic blocking seat 4 automatically blocks the observation port 11 to protect the surveying instrument body 10 from damage by external factors.

[0025] In one embodiment of the present invention, Figure 3-Figure 5As shown, a column 121 is provided on the inner wall of the operating port 12, and a conical elastic clamp 122 is symmetrically provided on the surface of the column 121; the manual drive mechanism 31 includes a lifting sleeve 311, the lifting sleeve 311 is sleeved on the outside of the column 121, and a reset spring 123 is fixedly connected to the inner bottom wall of the operating port 12; a handle 312 is fixedly connected to the upper end surface of the lifting sleeve 311, and a clamping hole 313 is opened at the lower end surface of the lifting sleeve 311 corresponding to the position of the conical elastic clamp 122, and is clamped and fixed with the conical elastic clamp 122; one end of the first transmission shaft 32 is connected to the top of the lifting sleeve 311, and the second transmission shaft 33 is vertically slidably connected to the inner wall of the column 121, one end of the second transmission shaft 33 is connected to the bottom of the lifting sleeve 311, and the other end of the second transmission shaft 33 passes through the lower end of the accommodating cylinder 1 and is connected to the top of the elastic metal support foot 2.

[0026] Specifically, the column 121 is arranged on the inner wall of the operating port 12, providing a stable supporting structure for the manual drive mechanism 31, and the conical elastic clamps 122 are symmetrically arranged on the surface of the column 121, and these clamps are used to clamp with the clamping holes 313 on the lifting sleeve 311, so as to fix the position of the lifting sleeve 311, and the lifting sleeve 311 is sleeved on the outside of the column 121 and is connected to the inner bottom wall of the operating port 12 through a reset spring 123. The reset spring 123 enables the lifting sleeve 311 to maintain an initial position when not subjected to external force, and the handle 312 is fixedly connected to the upper end surface of the lifting sleeve 311, so as to facilitate the user to operate the lifting sleeve 311, and the clamping holes 313 are opened on the lifting sleeve 311. The lower end surface of the lowering sleeve 311 corresponds to the position of the conical elastic clamp 122. When the lifting sleeve 311 is pressed down to a certain height, the clamping hole 313 is clamped with the clamp to fix the position of the lifting sleeve 311. One end of the first transmission shaft 32 is connected to the top of the lifting sleeve 311. As the lifting sleeve 311 moves up and down synchronously, the position of the surveying instrument body 10 is adjusted. The second transmission shaft 33 is vertically slidably connected to the inner wall of the column 121, and one end is connected to the bottom of the lifting sleeve 311. As the lifting sleeve 311 moves up and down synchronously, the second transmission shaft 33 slides up and down in the column 121, and simultaneously drives the elastic metal support foot 2 to expand or retract.

[0027] The working principle is as follows: the user holds the handle 312 and presses down the lifting sleeve 311. When the lifting sleeve 311 moves down, the first transmission shaft 32 moves down accordingly, and the position of the surveying instrument body 10 is adjusted synchronously. At the same time, the lifting sleeve 311 moves down and synchronously drives the second transmission shaft 33 to slide downward in the column 121. The second transmission shaft 33 moves down and drives the elastic metal support foot 2 to expand. When the lifting sleeve 311 moves down to a certain height, the clamping hole 313 is clamped with the conical elastic clamp 122 to fix the position of the lifting sleeve 311, thereby maintaining the surveying instrument body 10. To adjust the position of the surveying instrument body 10, the user only needs to press the conical elastic clamp 122 to separate it from the clamp hole 313. Under the elastic force of the reset spring 123, the lifting sleeve 311 moves upward. The upward movement of the lifting sleeve 311 synchronously drives the surveying instrument body 10 and the elastic metal support foot 2 to reset. The user can adjust the height of the surveying instrument body 10 and the expanded state of the elastic metal support foot 2 at the same time through simple up and down operations, thereby improving work efficiency and convenience of operation.

[0028] In one embodiment of the present invention, Figure 5 As shown, the second transmission shaft 33 passes through the lower end of the accommodating cylinder 1 and is threadedly connected to an annular fixing seat 331 on one end surface. The bottom of the annular fixing seat 331 is evenly provided with sockets. The top of the elastic metal support foot 2 passes through the socket and is fixed by bolts.

[0029] Specifically, the second transmission shaft 33 passes through the lower end of the accommodating cylinder 1 and is threadedly connected to an annular fixing seat 331 on one end surface. The annular fixing seat 331 plays a key connecting and fixing role. A plurality of sockets are evenly arranged at the bottom of the annular fixing seat 331. These sockets are used to accommodate and fix the top end of the elastic metal support foot 2. The top end of the elastic metal support foot 2 passes through the socket of the annular fixing seat 331. The top end of the elastic metal support foot 2 is fixed to the annular fixing seat 331 by bolts. This connection method ensures the stability and reliability of the elastic metal support foot 2.

[0030] The working principle is as follows: when the second transmission shaft 33 slides up and down in the column 121, it synchronously drives the annular fixing seat 331 to move up and down together. The movement of the annular fixing seat 331 drives the elastic metal support foot 2 to expand or retract through the fixing action of the socket and the bolt. When the elastic metal support foot 2 needs to be expanded, the second transmission shaft 33 moves downward and drives the annular fixing seat 331 to move downward to a suitable position, so that the elastic metal support foot 2 can be smoothly expanded. When the elastic metal support foot 2 needs to be retracted, the second transmission shaft 33 rises and drives the annular fixing seat 331 to reset to the initial position, and the elastic metal support foot 2 is retracted accordingly. This design makes the expansion and retraction of the elastic metal support foot 2 more stable and reliable. At the same time, it is also convenient for the user to control the expansion angle and expansion range of the elastic metal support foot 2 by adjusting the position of the second transmission shaft 33. This connection method also increases the structural strength and stability of the entire surveying and mapping aid.

[0031] In one embodiment of the present invention, Figure 2 As shown, the inner side wall of the guide groove 13 is provided with a limiting roller 131 , and the inner bottom wall of the guide groove 13 is integrally formed with an arc guide portion 132 .

[0032] Specifically, the guide groove 13 is a structural component with a specific shape and function, which is used to guide or carry the elastic metal support foot 2. A limiting roller 131 is installed on the inner wall of the guide groove 13. The function of the limiting roller 131 is to limit and guide the movement trajectory of the elastic metal support foot 2 moving in the guide groove 13 to prevent it from exceeding a predetermined range or path, and is used to accurately control the movement direction and position of the elastic metal support foot 2. On the inner bottom wall part of the guide groove 13, an arc guide portion 132 is provided by integral molding. Integral molding means that the arc guide portion 132 and the rest of the guide groove 13 are manufactured as a whole. Such a design can usually improve the strength and stability of the structure. The shape (arc) of the arc guide portion 132 helps to guide the elastic metal support foot 2 to move smoothly and continuously in the guide groove 13, especially when the elastic metal support foot 2 needs to change the direction of movement or perform curved movement.

[0033] In one embodiment of the present invention, Figure 1 As shown, a roller 21 is rotatably connected to the bottom of the elastic metal support foot 2, and the surface of the roller 21 is provided with anti-slip grooves. The outer surface of the roller 21 is in the same plane as the outer surface of the accommodating cylinder 1.

[0034] Specifically, the elastic metal support foot 2 is a support component made of elastic metal, which may be designed to provide stability and support force, and at the same time has a certain elasticity, can adapt to different ground conditions or withstand a certain impact force. At the bottom of the elastic metal support foot 2, rollers 21 are installed by a rotating connection. The four groups of rollers 21 in four directions not only play a limiting role, but also greatly improve the support stability by increasing the contact area with the ground. The surface of the roller 21 is designed with anti-slip grooves, which is to further increase the friction between the roller 21 and the ground to prevent sliding or loss of control during movement. The outer surface of the roller 21 is in the same plane as the outer surface of the containing cylinder 1, which means that when the roller 21 is in storage, it will not protrude from the outer surface of the containing cylinder 1, thereby maintaining the flatness of the entire structure. This design helps to reduce friction and resistance during movement or transportation and prevent bumps, while also keeping the structure compact and beautiful.

[0035] In one embodiment of the present invention, Figure 4 and Figure 6 As shown, the elastic sealing seat 4 includes a seat body 41 and a trapezoidal block 42. The seat body 41 is fixedly connected to the end surface of the first transmission shaft 32 that passes through the upper end of the accommodating cylinder 1. Mounting grooves are respectively provided on the surface of the seat body 41 corresponding to the position of the observation port 11. The trapezoidal block 42 is slidably connected to the inner wall of the mounting groove, and a compression spring is fixedly connected to the inner wall of the mounting groove; the observation port 11 is designed to be larger inside and smaller outside, and the inner wall of the observation port 11 is provided with an inclined guide portion 111, which is adapted to the outer dimensions of the trapezoidal block 42.

[0036] Specifically, the elastic blocking seat 4 is composed of a seat body 41 and a trapezoidal blocking block 42. Its main function is to block or open the observation port 11 to protect the surveying instrument body 10 from being damaged by external factors. The seat body 41 is the fixed part of the elastic blocking seat 4, which is fixedly connected to the end surface of the first transmission shaft 32 that penetrates into the upper end of the accommodating cylinder 1, which means that the position and movement of the seat body 41 are controlled by the first transmission shaft 32, thereby realizing the opening and closing of the elastic blocking seat 4. The surface of the seat body 41 is respectively provided with mounting grooves corresponding to the position of the observation port 11. These grooves are used to install and support the trapezoidal blocking block 42, and It is allowed to slide within a certain range. The trapezoidal block 42 is the movable part of the elastic blocking seat 4, which is slidably connected to the inner wall of the mounting slot. This design allows the trapezoidal block 42 to move in the slot when subjected to external force (such as the thrust of a compression spring), thereby blocking or opening the observation port 11. A compression spring is fixedly connected between the trapezoidal block 42 and the inner wall of the mounting slot. The function of the compression spring is to provide a continuous thrust for the trapezoidal block 42 to keep it in close contact with the observation port 11, thereby achieving effective blocking. When the observation port 11 needs to be opened, the external force can overcome the thrust of the spring to move the trapezoidal block 42.

[0037] The observation port 11 is an opening on the containing cylinder 1, which is used to observe or access the interior of the cylinder. It is designed to be larger inside and smaller outside, which means that the diameter of the observation port 11 is larger when viewed from the inside of the cylinder, and smaller when viewed from the outside. The inner wall of the observation port 11 is provided with an inclined guide portion 111, which is adapted to the outer dimensions of the trapezoidal block 42. The design of the inclined guide portion 111 helps the trapezoidal block 42 to enter or leave the observation port 11 more smoothly when moving, reducing friction and resistance. At the same time, this design also ensures that the trapezoidal block 42 can provide an effective seal when blocking the observation port 11.

[0038] In one embodiment of the present invention, Figure 1 As shown, a rotating cover 100 is threadedly connected to the top and the bottom of the accommodating cylinder 1 respectively; the bottom of the rotating cover 100 located at the top of the accommodating cylinder 1 is fixedly connected to a surveying instrument protection cover seat 101; the surveying instrument protection cover seat 101 is sleeved on the outside of the surveying instrument body 10 and is adapted to the outer dimensions of the surveying instrument body 10; the top of the rotating cover 100 located at the bottom of the accommodating cylinder 1 is fixedly connected to a counterweight seat 102.

[0039] Specifically, the rotating cover 100 is fixed to the top and bottom of the containing cylinder 1 by threaded connections, respectively. This design allows the rotating cover 100 to be easily unscrewed or tightened when needed to facilitate access to the interior of the containing cylinder 1 or to fix other components. The bottom of the rotating cover 100 located at the top of the containing cylinder 1 is fixedly connected to a surveying instrument protective cover seat 101, which is specially designed to accommodate and protect the surveying instrument body 10. The size of the surveying instrument protective cover seat 101 is adapted to the outer size of the surveying instrument body 10, which means that it can tightly wrap the surveying instrument body 10 to provide effective protection and support. The top of the rotating cover 100 located at the bottom of the containing cylinder 1 is fixedly connected to a counterweight seat 102. The function of the counterweight seat 102 is to increase the stability of the entire structure and make its center of gravity face downward to prevent tipping or movement during use. By adding a counterweight at the bottom, it can be ensured that the containing cylinder 1 and its internal components can remain stable during use and have a good use effect.

[0040] In one embodiment of the present invention, Figure 1 As shown, the number of observation ports 11, guide slots 13 and elastic metal support legs 2 is the same, and the number of observation ports 11, guide slots 13 and elastic metal support legs 2 is at least set to four groups.

[0041] It should be noted that the size of the observation port 11 described in this embodiment is larger than the size of the surveying instrument body 10 so as to leave space for operation.

[0042] Specifically, the number of observation ports 11, guide grooves 13 and elastic metal support feet 2 is the same, which means that each observation port 11 corresponds to a guide groove 13 and an elastic metal support foot 2. Such a design may be to ensure the balance and stability of the structure.
