Description

Technical Field

[0001] This invention relates to the field of engineering cost surveying technology, specifically to a portable on-site engineering cost surveying device. Background Technology

[0002] In the field of engineering cost estimation, on-site surveying is a crucial task, providing accurate data support for project budgeting, cost control, and schedule management. Currently, various devices for on-site engineering cost surveying are available on the market, which to some extent meet the needs of surveying work.

[0003] Most existing surveying devices have basic surveying functions. For example, some common surveying equipment is equipped with high-precision surveying instruments, which can accurately measure objects such as terrain and buildings. Some devices are also designed with adjustable height support structures to adapt to different terrains and surveying height requirements. However, these existing technologies still have many shortcomings in practical applications: (1) Insufficient portability: Many existing surveying devices are not compact in structure design, and the connection between components is complicated and lacks reasonable storage design. For example, the support and surveying instruments of some devices are fixedly connected, and cannot be folded or disassembled during carrying, resulting in a large overall size, occupying a lot of space, and causing great inconvenience to the staff in carrying and transporting them. This inconvenience is particularly obvious at engineering sites where surveying locations need to be changed frequently, which increases the labor intensity of the staff and reduces work efficiency. (2) Inconvenient height adjustment and poor stability: Although some surveying devices have height adjustment functions, the adjustment method is relatively cumbersome. For example, some devices use manual screw adjustment, which requires staff to spend a lot of time and effort to adjust the height. It is also difficult to ensure that the height of each support leg is consistent during the adjustment process, which can easily cause the surveying device to tilt and affect the surveying accuracy. In addition, the support structure of some devices is not stable enough. When encountering complex terrain or being disturbed by external forces, it is easy to shake or even tilt, which will not only damage the surveying instrument, but also threaten the safety of the staff. (3) Complex positioning and installation: The positioning and installation process between the surveying mechanism and the base of the existing surveying device is often quite complicated, requiring the use of a variety of tools for precise adjustment and fixation. This not only increases the installation time and difficulty, but also puts forward higher requirements for the technical level of the staff. In some urgent or complex surveying tasks, the complicated installation process may delay the work progress and affect the timeliness and accuracy of the surveying work. (4) Poor anti-slip performance: At the construction site, the ground conditions are complex and diverse, and there may be slippery or muddy conditions. The anti-slip performance of the existing surveying device base is limited. It is easy to slip on smooth ground, which will cause the surveying device to shift its position and affect the accuracy of the surveying results. At the same time, slipping may also cause safety accidents and damage to staff and equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a portable on-site engineering cost surveying device to solve the problems of insufficient portability, inconvenient height adjustment and poor stability, complex positioning and installation, and poor anti-slip performance in the existing technology, thereby improving the efficiency and accuracy of on-site engineering cost surveying.

[0005] Specifically, the technical solution provided by this invention is: a portable on-site engineering cost surveying device, comprising: The surveying and mapping organization includes a support frame, a surveying instrument is installed inside the support frame, and a control panel is located at the front of the support frame. The main body of the control panel includes a PCB board with a CPU main control chip, a power supply, and auxiliary control circuits. The base has a top surface connected to the surveying mechanism via a positioning mechanism, and the four sides of the base are rotatably connected to a height adjustment mechanism. The height adjustment mechanism includes a longitudinally arranged hydraulic cylinder, and the hydraulic push rod of the hydraulic cylinder is rotatably connected to the base. The base frame is fixed to the bottom of the hydraulic cylinder, and a counterweight is mounted on the bottom surface of the base frame. Bubble level, the bubble level is set on the base; The positioning mechanism includes a rotating base, on which a rotating disk is rotatably mounted, and a longitudinally placed limiting block is fixed on the rotating disk. The rotating disk is connected to a bracket through the limiting block.

[0006] Preferably, the top of the bracket is integrally formed with a handle, the side of the bracket is provided with a limiting hole, and the bottom of the bracket is provided with a limiting slot, the specification of which is compatible with the limiting block.

[0007] Preferably, the four sides of the base are machined with grooves, and the two inner sidewalls of the grooves are provided with bearing seats, and the height adjustment mechanism is rotatably connected to the bearing seats.

[0008] Preferably, the end of the hydraulic push rod is provided with a shaft bracket, and a horizontally placed rotating shaft is fixed inside the shaft bracket. The hydraulic push rod is rotatably connected to the shaft seat through the rotating shaft. Preferably, the bottom of the counterweight is processed with a rubber anti-slip layer, and the rubber anti-slip layer is processed with anti-slip texture.

[0009] Preferably, the top of the limiting block is machined with a limiting buckle made of high-elastic plastic. The limiting block is inserted into the limiting slot, and the limiting buckle moves close to the groove wall of the limiting slot until it extends out of the limiting hole and is fixed.

[0010] Preferably, a limiting spring is provided on the inner side of the limiting buckle.

[0011] Compared with the prior art, the advantages of this invention are: (1) Significantly improved portability: The top of the bracket is integrally molded with a handle, which is convenient for staff to carry. At the same time, the structure of each component is reasonably designed. When not in use, the height adjustment mechanism can be rotated and stored under the base, reducing the overall volume of the device and making it easy to transport and store. This effectively solves the problem of insufficient portability in the prior art. (2) Convenient height adjustment and strong stability: The hydraulic cylinder is used as the height adjustment mechanism. The height adjustment is achieved by the extension and retraction of the hydraulic push rod. The operation is simple and convenient, which greatly saves the adjustment time. Each hydraulic cylinder is independently connected to the base for rotation. During the adjustment process, it can automatically adapt to different terrains to ensure the levelness of the base. The design of the counterweight and rubber anti-slip layer enhances the stability of the device and avoids the problem of affecting the surveying accuracy and causing safety accidents due to the tilting or shaking of the device. This overcomes the defects of inconvenient height adjustment and poor stability in the prior art. (3) Simple and quick positioning and installation: The positioning mechanism adopts the design of limit plug and limit buckle. When installing the surveying mechanism, simply insert the limit plug into the limit slot, and the limit buckle will automatically pop out and be fixed in the limit hole, realizing quick positioning and installation. There is no need to use multiple tools for precise adjustment, which reduces the installation difficulty and the technical level requirements of the staff, improves work efficiency, and solves the problem of complex positioning and installation in the existing technology. (4) Superior anti-slip performance: The counterweight block assembled on the bottom surface of the base frame is processed with a rubber anti-slip layer, and the rubber anti-slip layer is provided with anti-slip texture, which greatly increases the friction between the device and the ground, effectively preventing the device from sliding on smooth, muddy and other complex ground, ensuring that the surveying device can work stably under various terrain conditions, improving the accuracy of the surveying results, and making up for the lack of good anti-slip performance in the existing technology.

[0022] like Figures 1 to 8 As shown, this embodiment provides a portable on-site engineering cost surveying device. The surveying mechanism 1 includes a support 101, which is an integrally formed structure with a handle 102 integrally formed on its top for easy carrying by staff, thus improving the portability of the device. The support 101 is hollow inside and is used to house the surveying instrument 103, which can accurately measure objects such as terrain and buildings, providing data support for engineering cost estimation. The front of the support 101 is equipped with a control panel 105, which includes a PCB board with a CPU main control chip, a power supply, and auxiliary control circuits. The surveying instrument 103 can be operated and controlled through the control panel 105. The side of the support 101 is provided with a limiting hole 104, and the bottom is provided with a limiting slot 106. The specification of the limiting slot 106 is adapted to the limiting plug 603 for connection with the positioning mechanism 6, so as to realize the positioning and installation of the surveying mechanism 1 on the base 2.

[0023] The base 2 is a flat plate structure that serves to support the surveying mechanism 1 and connect the height adjustment mechanism 3. The top surface of the base 2 is connected to the surveying mechanism 1 through the positioning mechanism 6, which fixes the surveying mechanism 1 in place. The four sides of the base 2 are all machined with grooves 201. The two inner sidewalls of the grooves 201 are provided with bearing seats 202, which provide rotation connection points for the height adjustment mechanism 3. When not in use, the height adjustment mechanism 3 can be rotated and stored in the grooves 201, reducing the overall size of the device and facilitating transportation and storage.

[0024] The height adjustment mechanism 3 includes a longitudinally arranged hydraulic cylinder 301. The hydraulic cylinder 301 achieves height adjustment through the extension and retraction of the hydraulic push rod 302, which is simple and convenient to operate and greatly saves adjustment time. The end of the hydraulic push rod 302 is provided with a shaft bracket 303, and a transversely arranged rotating shaft 304 is fixed inside the shaft bracket 303. The hydraulic push rod 302 is rotatably connected to the bearing seat 202 in the groove 201 of the base 2 through the rotating shaft 304. Each hydraulic cylinder 301 is independently rotatably connected to the base 2, which can automatically adapt to different terrains during the adjustment process and ensure the levelness of the base 2.

[0025] The base frame 4 is fixed to the bottom of the hydraulic cylinder 301, serving to support the entire device. A counterweight is mounted on the bottom of the base frame 4, with a rubber anti-slip layer machined on its bottom and anti-slip textured on the rubber anti-slip layer. This greatly increases the friction between the device and the ground, effectively preventing the device from sliding on smooth, muddy, or other complex surfaces. This ensures the surveying device can work stably under various terrain conditions, improving the accuracy of the surveying results.

[0026] The bubble level 5 is set on the base 2 to visually display the horizontal status of the base 2, so that the staff can ensure that the base 2 is in a horizontal position when adjusting the height adjustment mechanism 3, thereby improving the surveying accuracy.

[0027] The positioning mechanism 6 includes a rotating base 601, which is fixed to the top surface of the base 2. A rotating disk 602 is rotatably mounted on the rotating base 601. The rotating disk 602 can rotate around the rotating base 601 within a certain angle range, facilitating the adjustment of the installation angle of the surveying mechanism 1. A longitudinally placed limiting block 603 is fixed on the rotating disk 602. A limiting buckle 604 made of high-elastic plastic is machined to the top of the limiting block 603. A limiting spring 605 is provided inside the limiting buckle 604. This spring 605 is used when the surveying mechanism 1 is installed. When the limiting block 603 is inserted into the limiting slot 106 at the bottom of the bracket 101, the limiting buckle 604 moves close to the groove wall of the limiting slot 106. When it moves to the position of the limiting hole 104, the limiting buckle 604 automatically pops out and is fixed in the limiting hole 104 under the action of the limiting spring 605, realizing the rapid positioning and installation of the surveying mechanism 1 and the base 2. It eliminates the need for precise adjustment using multiple tools, reduces the installation difficulty and the technical requirements of the staff, and improves work efficiency.

[0028] Based on the above structural features, this embodiment also provides the method of use and working principle of the device: When the surveying device needs to be carried to the engineering cost site, since the top of the bracket 101 is integrally formed with a handle 102, the staff can directly hold the handle 102 and easily lift the entire surveying device. At the same time, the structure of each component is reasonably designed. In the non-use state, the hydraulic cylinder 301 in the height adjustment mechanism 3 can rotate around the bearing 202 in the groove 201 on the side of the base 2, so that the hydraulic push rod 302 is stored below the base 2, and the entire height adjustment mechanism 3 is stored below the base 2. This greatly reduces the overall size of the device, avoids interference between the components, facilitates the handling and storage of staff, and effectively solves the problem of insufficient portability in the prior art.

[0029] Upon arrival at the construction site, the staff first placed the device in a suitable location. Then, they began installing the surveying mechanism 1, with the positioning mechanism 6 playing a crucial role in this process. The rotating seat 601 of the positioning mechanism 6 is fixed to the top surface of the base 2. The rotating disk 602 is rotatably mounted on the rotating seat 601 and can rotate within a certain angle range around the rotating seat 601, facilitating subsequent adjustments to the installation angle of the surveying mechanism 1. A longitudinally placed limiting block 603 is fixed on the rotating disk 602. A limiting buckle 604 made of high-elastic plastic is machined to the top of the limiting block 603, and a limiting spring 605 is provided inside the limiting buckle 604.

[0030] The operator aligns the limiting slot 106 at the bottom of the support 101 of the surveying mechanism 1 with the limiting block 603 of the positioning mechanism 6, and slowly lowers the surveying mechanism 1 so that the limiting block 603 is inserted into the limiting slot 106. During this process, the limiting buckle 604 moves close to the groove wall of the limiting slot 106. Because the limiting buckle 604 is made of highly elastic plastic and has a limiting spring 605 on its inner side, the limiting buckle 604 will retract inward when compressed. When the limiting block 603 moves to the position of the limiting hole 104 on the side of the support 101, the limiting buckle 604 is no longer compressed by the groove wall of the limiting slot 106, and automatically pops out under the action of the limiting spring 605 and is fixed in the limiting hole 104. This achieves rapid positioning and installation of the surveying mechanism 1 and the base 2 without the need for precise adjustment using multiple tools, reducing the installation difficulty and the technical requirements for the operators, improving work efficiency, and solving the problem of complex positioning and installation in existing technologies.

[0031] After the surveying mechanism 1 is installed, the staff needs to adjust the height of the device according to the terrain and surveying height requirements. The device uses hydraulic cylinders 301 as the height adjustment mechanism 3, and each hydraulic cylinder 301 works independently. The hydraulic push rod 302 of the hydraulic cylinder 301 has a shaft bracket 303 at its end. A horizontally placed rotating shaft 304 is fixed inside the shaft bracket 303. The hydraulic push rod 302 is rotatably connected to the bearing seat 202 in the groove 201 of the base 2 through the rotating shaft 304.

[0032] Workers control the hydraulic system to extend and retract the hydraulic push rod 302 of the hydraulic cylinder 301. Since each hydraulic cylinder 301 is independently rotatably connected to the base 2, during adjustment, each cylinder 301 can automatically adjust its angle according to the terrain. For example, when the ground is uneven, if a certain hydraulic cylinder 301 is positioned lower, it will rotate around the bearing 202 by a certain angle during adjustment, allowing the hydraulic push rod 302 to adapt to terrain changes while extending and retracting, ensuring the base 2 remains level. Workers can visually assess the levelness of the base 2 by observing the bubble level 5 mounted on it. If the bubble is not centered on the level 5, the hydraulic cylinder 301 can be fine-tuned until the bubble is centered, ensuring the base 2 is level and improving surveying accuracy. This height adjustment method is simple and convenient to operate, greatly saving adjustment time and overcoming the shortcomings of inconvenient and unstable height adjustment in existing technologies.

[0033] After height adjustment, the device is in a stable working state. At this time, staff can operate and control the surveying instrument 103 housed inside the support 101 via the control panel 105 at the front of the surveying mechanism 1 support 101. The control panel 105 mainly includes a PCB board with a CPU main control chip, a power supply, and auxiliary control circuits. The CPU main control chip processes and analyzes the data collected by the surveying instrument 103, the power supply provides power to the entire surveying mechanism 1, and the auxiliary control circuits ensure that the various components can work together. The surveying instrument 103 starts working, accurately measuring the terrain, buildings, and other objects on site, and transmitting the measurement data to the CPU main control chip in the control panel 105. After processing the data, the CPU main control chip can transmit the data to external devices, such as computers and tablets, via wired or wireless means, so that staff can perform subsequent budget preparation, cost control, and schedule management, as well as other engineering cost-related work.

[0034] Throughout the surveying process, the base frame 4 plays a crucial supporting role. The base frame 4 is fixed to the bottom of the hydraulic cylinder 301, and a counterweight is mounted on its bottom surface. The bottom of the counterweight is machined with a rubber anti-slip layer, and this rubber anti-slip layer has anti-slip textures. At engineering sites, ground conditions are complex and varied, potentially including slippery or muddy surfaces. When the device is placed on the ground, the rubber anti-slip layer and anti-slip textures significantly increase the friction between the device and the ground, effectively preventing the device from sliding on smooth, muddy, or other complex surfaces. Even when encountering external interference or complex terrain, the device remains stable, ensuring normal operation under various terrain conditions, improving the accuracy of surveying results, and preventing safety accidents caused by device slippage. This protects personnel and equipment and overcomes the shortcomings of poor anti-slip performance in existing technologies.

[0035] After the surveying work is completed, the staff needs to disassemble and store the device. To disassemble the surveying mechanism 1, simply press the limiting buckle 604 by hand to retract it inwards, disengaging it from the limiting hole 104. Then, lift the surveying mechanism 1 upwards to pull the limiting insert 603 out of the limiting slot 106, thus completing the disassembly of the surveying mechanism 1. Next, rotate the height adjustment mechanism 3 out from under the base 2, restoring it to a portable state. Finally, the staff grasps the handle 102 at the top of the bracket 101 again and moves the entire device to the storage location, completing the entire workflow.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
