Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and particularly relates to a total station observation pier device. Background Technique

[0002] The total station observation pier is a commonly used fixed reference point device in surveying work, which is used for the placement and surveying operation of the total station. The bottom of the traditional total station observation pier device mostly adopts a concrete foundation, and the surrounding is backfilled with plain soil to increase its stability. The pier body mostly adopts a brick structure, and a forced centering plate is reserved at the top of the pier body to ensure the accurate centering and stable placement of the total station during the surveying process. The combined design of the concrete foundation and the brick pier body ensures the stability and durability of the observation pier to a certain extent.

[0003] Although the existing observation pier devices can meet the basic surveying requirements, they have some significant disadvantages. First of all, although the brick pier body is stable, its disassembly and assembly process is cumbersome and time-consuming, and it cannot be quickly installed and disassembled, which is particularly inconvenient in the case where the position of the observation pier needs to be frequently moved.

[0004] During the construction and maintenance of railways, the need to move the observation pier is particularly frequent. The laying and maintenance of railway lines usually involve long-distance surveys and the need for multiple surveying and positioning. It is necessary to frequently move the total station observation pier to ensure the surveying coverage and accuracy. Due to the complexity and weight of the traditional brick pier body, its disassembly, assembly and handling are very inconvenient, and it cannot quickly respond to the changing requirements of the construction site. In this case, not only a large amount of human and time resources are wasted, but also the construction progress may be delayed, affecting the efficiency and quality of the overall project. Especially in some railway maintenance operations that require emergency repairs, quickly deploying the observation pier is crucial, and the traditional brick pier body is obviously difficult to meet this requirement.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 10 , the present invention provides a total station observation pier device, including a base 1, the number of bases 1 is four, and further includes a pier bottom section 2, at least one pier installation section 3, a pier top section 4 and a forced centering plate 9; the lower end of the pier bottom section 2 is fixedly connected to the upper surfaces of the four bases 1, the upper end of the pier bottom section 2 is connected to the pier top section 4 through the pier installation section 3, and the forced centering plate 9 is connected to the upper surface of the pier top section 4.

[0032] During use, place the base 1 on the ground or fix it to the ground. The fixing method can be to fix the base 1 through a mechanical structure (bolt), or the base 1 can be directly built on the ground with building materials such as concrete. The pier bottom section 2 is fixedly connected to the base 1. Subsequently, connect the pier installation section 3 to the upper end of the pier bottom section 2, and finally connect the lower end of the pier top section 4 to the upper end of the pier installation section 3 to complete the construction of the observation pier device. Finally, connect the total station (not marked in the figure) to the forced centering plate 9. After the observation is completed, remove the total station first, and then disassemble the pier top section 4 and the pier installation section 3 in sequence.

[0033] It should be noted that in specific implementation, multiple pier installation sections 3 can be selected according to actual needs to adjust the overall height of the finally constructed observation pier device, thereby realizing the adjustment of the installation height of the total station.

[0034] By adopting the design of sequentially connecting the pier bottom section 2, the pier installation section 3 and the pier top section 4, the disassembly and assembly convenience and flexibility of the device are significantly improved. Compared with the traditional brick structure, the present invention has the functions of installation and disassembly, and is suitable for use scenarios that require frequent movement and adjustment of the measurement position. In addition, by selecting multiple pier installation sections 3, the overall height of the observation pier device can be flexibly adjusted to further meet the requirements for the installation height of the total station in different measurement environments, overcoming the problem that the installation height of the traditional observation pier is not adjustable due to its fixed structure, and ensuring the accuracy and safety of the measurement work.

[0035] Railway survey work usually requires efficient and frequent movement of survey reference points to cover long railway lines and multiple survey locations. The total station observation pier device provided by the utility model can be disassembled and reassembled, greatly improving the flexibility and efficiency of survey work and reducing the time and human resources required for the movement of the observation pier. At the same time, by flexibly adjusting the height of the pier body, it can adapt to the survey requirements at different positions of the railway line, ensuring the continuity and accuracy of survey work, thereby improving the overall efficiency and quality of railway construction and maintenance work.

[0036] Specifically, as Figure 2 shown, the bottom section 2 of the pier body includes four first support rods 21, and the four first support rods 21 are connected by first strengthening beams 22 arranged in a crosswise manner. The lower ends of the first support rods 21 are provided with flange plates, and these flange plates are fixedly connected to the base 1 through bolts. The setting of the first strengthening beams 22 is used to improve the stability between the first support rods 21, and the mutually crosswise first strengthening beams 22 are fixedly connected.

[0037] Specifically, the installation section 3 of the pier body includes four second support rods 31, and the four second support rods 31 are connected by second strengthening beams 32 arranged in a crosswise manner. The two mutually crosswise second strengthening beams 32 are fixedly connected, and the setting of the second strengthening beams 32 is used to improve the stability between the second support rods 31.

[0038] Specifically, the top section 4 of the pier body includes four third support rods 41 and a top plate 43, and the four third support rods 41 are connected by third strengthening beams 42 arranged in a crosswise manner. The two mutually crosswise third strengthening beams 42 are fixedly connected, and the setting of the third strengthening beams 42 is used to improve the stability between the third support rods 41. The top plate 43 is installed at the upper ends of the four third support rods 41, and the forced centering plate 9 is installed on the upper surface of the top plate 43. Bolts for connecting the total station are provided on the forced centering plate 9.

[0039] Specifically, the upper ends of the four first support rods 21 are provided with first insertion sleeves 211, the lower ends of the four second support rods 31 are provided with first insertion parts 311, and the first insertion parts 311 are used to be inserted into the first insertion sleeves 211. The upper ends of the four second support rods 31 are provided with second insertion sleeves 312, and the lower ends of the four third support rods 41 are provided with second insertion parts 411.

[0040] In actual installation, by inserting the first insertion part 311 of the installation section 3 of the pier body into the first insertion sleeve 211, the installation of the installation section 3 of the pier body can be completed. Subsequently, by inserting the second insertion part 411 of the top section 4 of the pier body into the second insertion sleeve 312 of the installation section 3 of the pier body, the plug-in connection between the bottom section 2 of the pier body, the installation section 3 of the pier body, and the top section 4 of the pier body can be completed. When disassembling, the top section 4 of the pier body and the installation section 3 of the pier body can be removed in sequence.

[0041] Specifically, in order to ensure the stable connection between the bottom section 2 of the pier shaft, the installation section 3 of the pier shaft, and the top section 4 of the pier shaft, a first locking assembly 5 is provided on the first support rod 21 near the first socket sleeve 211. A first plugging assembly 6 is provided at the lower end of the second support rod 31, and the first plugging portion 311 is connected to the lower end of the first plugging assembly 6. A second locking assembly 7 is provided on the second support rod 31 near the second socket sleeve 312. A second plugging assembly 8 is provided at the lower end of the third support rod 41, and the second plugging portion 411 is connected to the lower end of the second plugging assembly 8. During use, the first plugging assembly 6 is locked by the first locking assembly 5, thus completing the installation between the bottom section 2 of the pier shaft and the installation section 3 of the pier shaft, and preventing the installation section 3 of the pier shaft from falling off relative to the bottom section 2 of the pier shaft. The second plugging assembly 8 is locked by the second locking assembly 7, and the installation between the top section 4 of the pier shaft and the installation section 3 of the pier shaft can be completed, preventing the top section 4 of the pier shaft from falling off relative to the installation section 3 of the pier shaft.

[0042] Specifically, the first locking assembly 5 includes a housing 51, a rotating shaft 52, a rotating wheel 53, a pulling rope 54, a first spring 55, and a clamping block 56. The housing 51 is connected to the first support rod 21. An installation space communicating with the first socket sleeve 211 is provided inside the first support rod 21, and the housing 51 extends into the installation space. The clamping block 56 is slidably installed inside the housing 51. A baffle 511 is provided inside the housing 51. The first spring 55 is provided between the baffle 511 and the clamping block 56. The rotating wheel 53 is provided inside the housing 51. The rotating shaft 52 passes through the rotating wheel 53 and the housing 51, and the rotating shaft 52 is fixedly connected to the rotating wheel 53 and rotatably connected to the housing 51. One end of the rotating shaft 52 is connected with a dial 521. One end of the pulling rope 54 is fixedly connected to the rotating wheel 53, and the other end of the pulling rope 54 is fixedly connected to the clamping block 56. A guiding inclined surface 561 is provided on the clamping block 56.

[0043] The first plugging assembly 6 includes an installation pipe body 61, a limiting snap ring 62, a second spring 63, a connecting rod 64, and a plugging member 65. The installation pipe body 61 is connected to the first plugging portion 311. The first plugging portion 311 is a tubular structure. The limiting snap ring 62 is provided inside the first plugging portion 311. The plugging member 65 is movably installed inside the first plugging portion 311. The second spring 63 is provided between the limiting snap ring 62 and the plugging member 65. The connecting rod 64 is connected to the plugging member 65. The connecting rod 64 is an L-shaped bent rod. A first chute 611, a second chute 612, and a card slot 613 which are vertical and horizontal are provided on the side wall of the installation pipe body 61. The first chute 611, the second chute 612, and the card slot 613 communicate with each other. One end of the connecting rod 64 extends out of the first chute 611. A clamping portion 651 which cooperates with the clamping block 56 is provided on the plugging member 65.

[0044] Among them, the elastic force of the second spring 63 is greater than the elastic force of the first spring 55.

[0045] Before the installation of the pier body installation section 3, the connecting rod 64 is located in the card slot 613, and at the same time, the second spring 63 is compressed. During installation, the first insertion part 311 of the pier body installation section 3 is inserted into the first insertion sleeve 211. Subsequently, the connecting rod 64 is lifted upward to disengage the connecting rod 64 from the card slot 613. Then, the connecting rod 64 is rotated so that the connecting rod 64 moves in the second chute 612. At the same time, the connecting rod 64 also drives the plug-in part 65 to move. When the connecting rod 64 moves to the first chute 611, the connecting rod 64 is released. Next, the elastic force of the second spring 63 causes the plug-in part 65 to move downward. When the plug-in part 65 contacts the guiding inclined surface 561 of the locking block 56, the plug-in part 65 continues to move downward. Under the action of the guiding inclined surface 561, the locking block 56 retracts into the housing 51, and at the same time, the first spring 55 is compressed. As the plug-in part 65 continues to move downward, when the clamping part 651 corresponds to the locking block 56, the locking block 56 extends out and forms a clamping connection with the clamping part 651. The lower surface of the locking block 56 is a plane, so the plug-in part 65 cannot be separated from the first locking assembly 5. At the same time, the connecting rod 64 also contacts the bottom of the first chute 611. At this time, the first locking assembly 5 is connected to the first insertion assembly 6 and cannot be separated. The four first support rods 21 and the four second support rods 31 are connected in sequence, thereby realizing the connection between the bottom section 2 of the pier body and the pier body installation section 3, avoiding the separation between the bottom section 2 of the pier body and the pier body installation section 3, and ensuring the stable connection between the bottom section 2 of the pier body and the pier body installation section 3.

[0046] When it is necessary to disassemble the pier body installation section 3 relative to the bottom section 2 of the pier body, the dial 521 is rotated. The dial 521 drives the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 drives the rotating wheel 53 to rotate. The rotation of the rotating wheel 53 winds the pulling rope 54. The pulling rope 54 drives the locking block 56 to retract into the housing 51. Subsequently, the connecting rod 64 can be lifted upward. The connecting rod 64 drives the plug-in part 65 to move upward. Then, the connecting rod 64 is toggled into the card slot 613. The connection between the four first support rods 21 and the four second support rods 31 is cancelled in sequence. Subsequently, the pier body installation section 3 and the bottom section 2 of the pier body can be disassembled. Just lift the pier body installation section 3 upward.

[0047] It should be noted that the second locking assembly 7 of the present invention has exactly the same structure as the first locking assembly 5, and the second insertion assembly 8 has exactly the same structure as the first insertion assembly 6.

[0048] After the upper end of the top pier section 4 is inserted and connected to the upper end of the pier installation section 3, by controlling the locking formed between the second insertion assembly 8 and the second locking assembly 7, the installation and fixation between the top pier section 4 and the pier installation section 3 can be completed, ensuring a stable connection between the top pier section 4 and the pier installation section 3. During disassembly, controlling the second locking assembly 7 can cancel the locking of the second insertion assembly 8. The operating methods and operating principles of the second locking assembly 7 and the first locking assembly 5 are exactly the same, and the operating methods and operating principles of the second insertion assembly 8 and the first insertion assembly 6 are exactly the same. Therefore, the second locking assembly 7 and the second insertion assembly 8 will not be elaborated in detail anymore.

[0049] Specifically, a lightning rod 44 is provided at the upper end of the top plate 43. The lightning rod 44 is used to protect the total station observation pier device and the total station equipment from the influence of lightning strikes, ensure the safe operation of the equipment under thunderstorm weather conditions, and prevent equipment damage and data loss caused by lightning strikes.
