Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, and in particular to a surveying and mapping device for highway engineering cost estimation. Background Technology

[0002] In the field of highway engineering cost surveying, the support structure of existing surveying equipment has significant defects. Traditional tripods often have fixed-length or simple telescopic support rods, and the contact point with the ground often uses a single plane or a small area support point. When the surveying environment is a complex terrain such as mountains or slopes, single-point support is prone to tilting due to uneven ground, causing the surveying instrument to shake and greatly affecting data accuracy.

[0003] Meanwhile, the existing mechanisms for switching between movement and fixation of the equipment have significant shortcomings. Most surveying equipment requires manual handling of tripods for relocation. In large-scale surveying operations, frequent disassembly and assembly not only consume a large amount of manpower but also severely reduce work efficiency. Although some equipment is equipped with casters, it lacks a reliable lifting and fixing mechanism. During movement, the wheels are prone to slipping due to uneven ground, and when fixed, additional weights or manual support are required, making rapid and stable state switching impossible. This design flaw makes it highly susceptible to data loss due to equipment displacement in sudden weather or complex road conditions, increasing the risk of rework.

[0004] Therefore, it is necessary to provide surveying equipment for highway engineering cost estimation to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a surveying device for highway engineering cost estimation, which solves the problems in the background art. To solve the above-mentioned technical problems, the present invention provides a surveying device for highway engineering cost estimation, comprising a mounting platform, a surveying instrument mounted on the top surface of the mounting platform, a mounting base fixed to the periphery of the mounting platform, one end of a triangular bracket movably mounted inside the mounting base, the mounting base providing a mounting fulcrum for the triangular bracket, and the triangular bracket adjustable in support angle through its movable connection with the mounting base; the other end of the triangular bracket is connected to an adjusting support rod, an adjusting cavity is provided at the bottom of the triangular bracket, the adjusting support rod is slidably inserted into the adjusting cavity, a fixing hole is provided on the surface of the triangular bracket, and a fixing hole is provided on the surface of the adjusting support rod. It has adjustment holes, and fasteners pass through the fixing holes and adjustment holes to fix them. The adjustment cavity provides a channel for the extension and retraction of the adjustment support rod. The fixing holes and adjustment holes are engaged by fasteners to fix the adjustment support rod in different extension and retraction positions, thereby adjusting the support height of the device to adapt to different terrain requirements. The bottom end of the adjustment support rod is equipped with toothed cones, and multiple toothed cones are installed at equal intervals at the bottom end of the adjustment support rod. The adjustment support rod can extend and retract relative to the triangular bracket. Together with the toothed cones to enhance the grip of the device in complex terrain, they provide stable support for the mounting platform and surveying instruments, ensuring surveying accuracy.

[0006] Preferably, a mounting column is installed at the center of the bottom surface of the mounting platform. The bottom of the mounting column has a mounting cavity, inside which an electric jack is installed. The mounting column provides installation space for the electric jack. A movable plate is installed at the output end of the electric jack, and casters are installed on the bottom surface of the movable plate. The electric jack can drive the movable plate and casters to rise and fall. Multiple casters are installed at equal intervals on the bottom surface of the movable plate. The evenly distributed casters ensure uniform force on the movable plate, allowing it to rise and fall synchronously under the drive of the electric jack, ensuring the stability of the device during movement and preventing tilting or difficulty in movement due to uneven force. When the electric jack extends, the casters contact the ground and support the device, facilitating movement. When retracted, the casters retract, and the device is supported and fixed by a triangular bracket and an adjusting support rod, enabling rapid switching between movement and fixation.

[0007] Preferably, the bottom end of the triangular bracket has an adjustment cavity, and the adjustment support rod is slidably inserted into the adjustment cavity. The surface of the triangular bracket has a fixing hole, and the surface of the adjustment support rod has an adjustment hole. The adjustment support rod is fixed to the triangular bracket by fasteners. The adjustment cavity provides a channel for the extension and retraction of the adjustment support rod. The fixing hole and the adjustment hole are engaged by fasteners, so that the adjustment support rod can be fixed in different extension and retraction positions, thereby adjusting the support height of the device to adapt to different terrain requirements.

[0008] Preferably, multiple adjustment holes are provided, and the multiple adjustment holes are equally spaced on the surface of the adjustment support rod. The equally spaced adjustment holes provide more fixed position options for the adjustment support rod, making the adjustment of the support height more flexible and precise, and better adapting to the height differences of different terrains.

[0009] Preferably, multiple casters are installed, and the multiple casters are installed at equal intervals on the bottom surface of the moving plate. The equidistant distribution of casters can make the moving plate bear force evenly and lift and lower synchronously under the drive of the electric push rod, ensuring the stability of the device when moving and avoiding the device tilting or movement difficulties caused by uneven force.

[0010] Preferably, a suitable controller is installed on the mounting platform. The controller is compatible with other electric components of the device and serves as a control center to receive operation commands and control the extension and retraction of the electric push rod, realize the lifting and lowering of the casters, coordinate the device to complete the switching between movement and fixation, and improve the convenience and efficiency of operation.

[0011] Compared with related technologies, the highway engineering cost surveying device provided by this utility model has the following beneficial effects: Compared with existing technologies, the adjustable support rod can slide relative to the triangular bracket, which can flexibly adjust the support length to adapt to different terrain height differences; when the multiple equidistant toothed cones at the bottom contact the ground, they can increase the contact area and embed into the ground surface, improve the support stability under complex terrain (such as mountains and slopes), reduce the shaking of surveying instruments caused by uneven ground, and ensure data accuracy.

[0012] Compared to existing technologies, the electric jack inside the mounting column can drive the moving plate and casters to rise and fall, enabling rapid switching between mobile and fixed states. When moving, the casters are lowered to facilitate the overall movement of the device, reducing the intensity of manual handling; when fixed, the casters are retracted and supported by the triangular bracket and adjusting support rod, eliminating the need for additional weight or manual support, improving the efficiency of large-area surveying operations, and reducing the risk of data loss due to device displacement in case of emergencies.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1 Please refer to the following: Figure 1-4The surveying device for highway engineering cost estimation includes a mounting platform 1. A surveying instrument 7 is bolted to the center of the top surface of the mounting platform 1, a rigid connection that prevents relative displacement between the instrument and the platform during surveying. Mounting bases 2 are welded to the circumference of the mounting platform 1, with three evenly distributed along the circumference. One end of a triangular bracket 3 is movably mounted inside the mounting base 2 via a pin. The pin and the connection hole between the mounting base 2 and the triangular bracket 3 are clearance-fitted, allowing the triangular bracket 3 to rotate within a certain angle range around the pin. The mounting base 2 provides a stable mounting point for the triangular bracket 3. This movable connection between the triangular bracket 3 and the mounting base 2 allows for flexible adjustment of the support angle to adapt to different terrain inclinations. The other end of the triangular bracket 3 is connected to an adjusting support rod 4. Specifically, the bottom of the triangular bracket 3 has a cylindrical adjusting cavity, the inner diameter of which is slightly larger than the outer diameter of the adjusting support rod 4. The adjusting support rod 4 is cylindrical and slidably inserted into the adjusting cavity, ensuring smooth extension and retraction. A fixing hole 8 is formed on the surface of the triangular bracket 3 along its length. Multiple adjusting holes 9 are formed on the surface of the adjusting support rod 4 along its length. The fixing hole 8 and the adjusting holes 9 have the same diameter. The adjusting support rod 4 is fixed to the triangular bracket 3 by bolts and nuts passing through the fixing holes 8 and adjusting holes 9. Tightening the nuts secures the adjusting support rod 4 to the triangular bracket 3, preventing relative slippage. The adjusting cavity provides a guide channel for the extension and retraction of the adjusting support rod 4. The fixing hole 8 and the adjusting holes 9, through fastener engagement, can fix the adjusting support rod 4 at different extension and retraction positions, thereby precisely adjusting the support height of the device to adapt to different terrain height differences. A toothed cone 10 is welded to the bottom end of the adjusting support rod 4. The toothed cone 10 has a triangular pyramidal structure, and three toothed cones 10 are installed in an equilateral triangle pattern, evenly spaced on the end face of the bottom of the adjusting support rod 4. The adjustable support rod 4 can extend and retract relative to the triangular bracket 3. Together with the toothed cone 10, it enhances the grip of the device on complex terrain. When the device is placed on uneven ground such as mountains or slopes, the three toothed cones 10 can be embedded in different ground points to increase the contact area and friction with the ground, effectively preventing the device from tilting. Together, they provide stable support for the mounting platform 1 and the surveying instrument 7, ensuring surveying accuracy.

[0018] Example 2 Please refer to the following: Figure 1-4A mounting column 6 is bolted to the center of the bottom surface of the mounting platform 1. The mounting column 6 is a hollow cylindrical structure with a cylindrical mounting cavity 12 at its bottom end. The inner diameter of the mounting cavity 12 matches the outer diameter of the electric jack 13. The electric jack 13 is fixedly installed inside the mounting cavity 12 by bolts. The mounting column 6 provides a closed and stable installation space for the electric jack 13, preventing external debris from affecting its operation. The piston rod at the output end of the electric jack 13 is bolted to the center of the top surface of the moving plate 5 via a flange. The moving plate 5 is a square steel plate, and casters 11 are bolted to the bottom surface of the moving plate 5. The casters 11 are of the model with a braking function. The electric jack 13 can drive the moving plate 5 and the casters 11 to rise and fall vertically. Furthermore, four casters 11 are installed, located at the four corners of the bottom surface of the movable plate 5, arranged in a rectangular, equidistant pattern. This equidistant distribution of the casters 11 ensures even force distribution on the movable plate 5, allowing it to rise and fall synchronously under the drive of the electric push rod 13. This guarantees the stability of the device during movement and prevents tilting or difficulty in movement due to uneven force distribution. When the electric push rod 13 extends, the piston rod pushes the movable plate 5 downwards, causing the casters 11 to contact the ground and lift the entire device. At this time, the triangular bracket 3 and the adjusting support rod 4 are removed from the ground, and the rolling characteristics of the casters 11 allow for easy movement of the device. When the electric push rod 13 retracts, the piston rod drives the movable plate 5 and the casters 11 upwards back into the mounting cavity 12. The center of gravity of the device shifts downwards, and the triangular bracket 3 and the adjusting support rod 4 re-contact the ground, achieving stable fixation through the previously adjusted support structure. This allows for rapid switching between movement and fixation, eliminating the need for manual handling and additional fixing operations, thus improving work efficiency.

[0019] Example 3 Please refer to the following: Figure 1-4The triangular bracket 3 has an adjustment cavity at its bottom, which is a blind hole structure. Its inner wall is polished to reduce frictional resistance. The adjustment support rod 4 is slidably inserted into the adjustment cavity. The outer wall of the adjustment support rod 4 is also smoothed. The clearance between the two is controlled between 0.1-0.2mm to ensure smooth extension and retraction of the adjustment support rod 4 without significant wobbling. The surface of the triangular bracket 3 has a fixing hole 8, which is a through hole. The surface of the adjustment support rod 4 has an adjustment hole 9, which is also a through hole. The adjustment support rod 4 is fixed to the triangular bracket 3 by bolts, washers, and nuts passing through the fixing hole 8 and the adjustment hole 9. The washers increase the contact area and prevent damage to the surfaces of the triangular bracket 3 and the adjustment support rod 4 when the nut is tightened. The adjustment cavity provides a precise guide channel for the extension and retraction of the adjustment support rod 4, ensuring the verticality of the adjustment direction. The fixing hole 8 and the adjustment hole 9 are fitted with fasteners to fix the adjustment support rod 4 at different extension and retraction positions, thereby adjusting the support height of the device to adapt to different terrain requirements. Through this structural fit, the device can keep the mounting platform 1 level on terrains of different heights, providing a stable working platform for the surveying instrument 7.

[0020] Example 4 Please refer to the following: Figure 1-4 Multiple adjustment holes 9 are provided, and these holes 9 are equidistantly located on the surface of the adjustment support rod 4 along its length. The distance between two adjacent adjustment holes 9 is 5 cm. The equidistantly distributed adjustment holes 9 provide more options for fixing the adjustment support rod 4, enabling the adjustment accuracy of the support height to reach 5 cm. This allows for better adaptation to different terrain height differences. By selecting adjustment holes 9 at different positions to cooperate with fixing holes 8, the support height of the device can be adjusted in a stepped manner, meeting the height requirements of different surveying scenarios and further enhancing the terrain adaptability of the device.

[0021] Example 5 Please refer to the following: Figure 1-4 Multiple casters 11 are installed, and these casters 11 are bolted at equal intervals to the bottom surface of the moving plate 5. The axles of the casters 11 are parallel to the bottom surface of the moving plate 5, ensuring that the casters 11 can roll horizontally. The equidistant distribution of the casters 11 ensures that the moving plate 5 is subjected to uniform force and rises and falls synchronously under the drive of the electric push rod 13. Each caster 11 bears a basically the same load, avoiding damage to the casters 11 due to excessive local load, and ensuring the stability of the device during movement. When the device moves on uneven surfaces, the multiple casters 11 can disperse the impact force from the bumps in the road, preventing the device from tilting or becoming difficult to move. At the same time, the multiple casters 11 also improve the stability of the device during movement and prevent the device from tipping over during movement.

[0022] Example 6 Please refer to the following: Figure 1-4 A suitable controller is bolted to the mounting platform 1. The controller contains a control circuit and is electrically connected to the motor of the electric jack 13 via wires. The controller's control panel has up and down buttons. The controller is compatible with other electric components of the device and acts as a control center, receiving operating commands from the operator. When the up button is pressed, the controller controls the motor of the electric jack 13 to rotate forward, extending the piston rod; when the down button is pressed, the controller controls the motor of the electric jack 13 to rotate in reverse, retracting the piston rod, thus raising and lowering the caster wheel 11. The controller coordinates the switching between movement and fixation, making operation convenient and responsive, improving ease of use and efficiency, ensuring rapid position transfer and fixation in large-area surveying operations, and reducing wasted time.

[0023] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0024] The working principle of the highway engineering cost surveying device provided by this utility model is as follows: The core of this highway engineering cost surveying device lies in the coordinated operation of an adjustable support structure and a lifting and moving mechanism to achieve stable surveying and convenient movement. In terms of support and height adjustment, the tripod 3 is fixed to the side of the mounting platform 1 via the mounting base 2, providing basic support for the entire device. When it is necessary to adapt to different terrains, the fasteners between the fixing holes 8 on the surface of the tripod 3 and the adjustment holes 9 on the surface of the adjustment support rod 4 are loosened. The adjustment support rod 4 can slide within the adjustment cavity at the bottom of the tripod 3, thereby changing the overall support height. After adjusting to the appropriate position, the fasteners are re-passed through the corresponding fixing holes 8 and adjustment holes 9 to fix the adjustment support rod 4 to the tripod 3. At this time, the multiple toothed cones 10 at the bottom of the adjustment support rod 4 are in contact with the ground. The toothed cones 10 are embedded in the ground surface, using multiple contact points to disperse pressure, enhancing the device's anti-tilt capability in complex terrain, and ensuring the stability of the surveying instrument 7 on the mounting platform 1. Regarding the switching between moving and fixed positions, the mounting column 6 at the bottom center of the mounting platform 1 has a mounting cavity 12. The electric jack 13 is installed inside the mounting cavity 12, and its output end is connected to the moving plate 5. Multiple equidistant casters 11 are installed at the bottom of the moving plate 5. When the device needs to be moved, the controller on the mounting platform 1 activates the electric jack 13, which extends and pushes the moving plate 5 downward, causing the casters 11 to contact the ground and lift the entire device. The triangular bracket 3 and the adjusting support rod 4 are then lifted off the ground, allowing the device to be easily moved to the target position with the help of the casters 11. After reaching the position, the controller controls the electric jack 13 to retract, causing the moving plate 5 and the casters 11 to retract upward back into the mounting cavity 12. The center of gravity of the device shifts downward, and the triangular bracket 3 and the adjusting support rod 4 re-contact the ground, achieving stable fixation through the previously adjusted support structure. Then, the surveying instrument 7 can be operated for surveying operations. Throughout the process, the controller acts as the command center, coordinating the actions of the electric jack 13 to ensure the orderly cooperation of all components and guarantee that the device can efficiently and stably complete the surveying task in different scenarios.

The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.
