Description

Technical Field

[0001] This utility model relates to the field of urban planning technology, and in particular to a device for marking and positioning urban planning land use. Background Technology

[0002] In urban planning, marking and positioning stakes are frequently used. These stakes are tools for precisely marking locations within urban planning land areas. Their main function is to clarify land boundaries and planning scope, helping planners and construction workers accurately determine land locations and providing precise positioning references for subsequent land development and construction projects. This effectively avoids problems such as land location deviations during construction. In existing technologies, when using helical stakes for marking, large equipment is typically used to screw the stakes into the ground. During the process of screwing the stakes into the ground, when the soil freezes, the torque on the stake increases sharply due to the significant resistance it needs to overcome. This can easily lead to stake breakage if the stake's strength limit is exceeded. Since stake breakage and damage significantly increase costs, this urban planning land marking and positioning stake device is proposed to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A land use marker and positioning device for urban planning includes an upper pile body, the bottom of which contacts a lower pile body. A helical blade is fixedly connected to the outer side of the lower pile body, and a pile head is contacted at the bottom inner side of the lower pile body. A rotating block is fixedly connected to the top of the lower pile body, and the rotating block penetrates the upper pile body. The rotating block is rotatably connected to the upper pile body. A fixed rod is contacted at the top inner side of the upper pile body. A threaded shaft is rotatably connected to the center of the outer side of the fixed rod, and the threaded shaft penetrates the fixed rod. A slider is helically connected to the outer side of the threaded shaft, and the slider is slidably connected to the upper pile body. A connecting protective shaft is provided at the bottom of the slider, and the connecting protective shaft penetrates the upper pile body and the lower pile body, and the connecting protective shaft is in contact with the upper pile body and the lower pile body.

[0006] As a further improvement of this utility model, an indicator block is fixedly connected to the bottom outer end of the upper pile body and the top outer end of the lower pile body, and the indicator blocks are evenly distributed on the outer sides of the upper pile body and the lower pile body.

[0007] As a further improvement of this utility model, a bolt is spirally connected to the bottom outer side of the lower pile body, and the bolt penetrates through the lower pile body, and the bolt is spirally connected to the pile head.

[0008] As a further improvement of this utility model, springs are fixedly connected to both the left and right ends of the inner side of the fixing rod, and a locking block is fixedly connected to the other end of the spring. The locking block is slidably connected to the fixing rod and engages with the upper pile body. A push block that penetrates the fixing rod is fixedly connected to one end of the outer side of the locking block, and the push block is slidably connected to the fixing rod.

[0009] As a further improvement of this utility model, the outer top of the connecting protection shaft is provided with an external thread, the inner bottom of the slider is provided with an internal thread, and the connecting protection shaft and the slider are spirally connected.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Urban planning land use marking and positioning stake device: This device consists of a threaded shaft, a slider, a connecting protective shaft, an upper stake body, and a lower stake body. When marking urban planning land use, the upper stake body is rotated so that the indicator block on its outer side aligns with the indicator block on the outer side of the lower stake body. Then, the threaded shaft is rotated to connect with the slider, further controlling the slider to drive the connecting protective shaft, which passes through the upper stake body, through the lower stake body. The device is then screwed into the ground using external heavy machinery. During this process, if the underground soil freezes, causing the device to be subjected to a torque exceeding its strength limit, the reusable connecting protective shaft will break, protecting the device. When the torque monitoring equipment on the external screwing device detects a sharp decrease in the torque during insertion, the device can be removed. By preventing the reusable connecting protective shaft from breaking when subjected to a torque exceeding its strength limit, the device can be protected from overall breakage, thus reducing costs.

[0012] 2. The urban planning land use marker positioning stake device, through the setting of springs, locking blocks, sliders and connecting protective shafts, when the connecting protective shaft breaks multiple times and reaches its maximum service life, push blocks push the locking blocks to compress the springs and disengage from the upper stake body. Then, the slider is removed from the upper stake body by the fixing rod and threaded shaft. Then, the remaining part of the connecting protective shaft is disengaged from the slider by rotating the screw connection, which facilitates the replacement of the connecting protective shaft that has reached its maximum service life. The operation is simple and convenient. Attached Figure Description

[0020] Example 1

[0021] like Figure 1-4 As shown, the urban planning land use marker positioning stake device includes an upper stake body 1, the bottom end of which contacts a lower stake body 2. A spiral blade 3 is fixedly connected to the outer side of the lower stake body 2, and a stake head 4 is contacted at the bottom inner side of the lower stake body 2. A rotating block 5 is fixedly connected to the top of the lower stake body 2, and the rotating block 5 passes through the upper stake body 1. The rotating block 5 is rotatably connected to the upper stake body 1. A fixed rod 6 is contacted at the top inner side of the upper stake body 1. A threaded shaft 7 is rotatably connected to the center of the outer side of the fixed rod 6, and the threaded shaft 7 passes through the fixed rod 6. A slider 8 is spirally connected to the outer side of the threaded shaft 7, and the slider 8 is slidably connected to the upper stake body 1. A connecting protective shaft 9 is provided at the bottom of the slider 8, and the connecting protective shaft 9 passes through the upper stake body 1 and the lower stake body 2. The connecting protective shaft 9 is in contact with the upper stake body 1 and the lower stake body 2.

[0022] Example 2

[0023] like Figure 1-2As shown, in order to solve the problem of inconvenience in accurately controlling the connection and protection shaft 9 to pass through the lower pile body 2, an indicator block 10 is fixedly connected to the bottom outer side of the upper pile body 1 and the top outer side of the lower pile body 2. The indicator blocks 10 are evenly distributed on the outer side of the upper pile body 1 and the outer side of the lower pile body 2. By rotating the upper pile body 1, the indicator block 10 on the outer side of the upper pile body 1 is aligned with the indicator block 10 on the outer side of the lower pile body 2, which facilitates accurate control of the connection and protection shaft 9 to pass through the lower pile body 2.

[0024] Example 3

[0025] like Figure 2 As shown, in order to solve the problem of the difficulty in removing the broken connecting protective shaft 9 inside the lower pile body 2, a bolt 11 is spirally connected to the bottom outer side of the lower pile body 2, and the bolt 11 penetrates the lower pile body 2. The bolt 11 is spirally connected to the pile head 4. By rotating the bolt 11, the spiral connection with the pile head 4 is disengaged, and then the pile head 4 is separated from the lower pile body 2, which facilitates the removal of the broken connecting protective shaft 9 inside the lower pile body 2.

[0026] Example 4

[0027] like Figure 2-3 As shown, in order to solve the problem of the inconvenience of removing the connecting protection shaft 9 when it has reached its maximum usability after multiple breaks, springs 12 are fixedly connected to both the left and right ends of the inner side of the fixing rod 6. The other end of the spring 12 is fixedly connected to a locking block 13, and the locking block 13 is slidably connected to the fixing rod 6. The locking block 13 is engaged with the upper pile body 1. A push block 14 that penetrates the fixing rod 6 is fixedly connected to one end of the outer side of the locking block 13, and the push block 14 is slidably connected to the fixing rod 6. After the push block 14 pushes the locking block 13 to compress the spring 12, it disengages from the upper pile body 1. Then, the slider 8 is removed from the upper pile body 1 through the fixing rod 6 and the threaded shaft 7, which facilitates the removal of the connecting protection shaft 9 when it has reached its maximum usability after multiple breaks.

[0028] Example 5

[0029] like Figure 2 and Figure 4 As shown, in order to solve the problem that it is inconvenient to remove the connecting protection shaft 9 when it has reached its maximum use level for replacement, the outer top of the connecting protection shaft 9 is provided with an external thread, the inner bottom of the slider 8 is provided with an internal thread, and the connecting protection shaft 9 and the slider 8 are connected by a screw. By rotating the connecting protection shaft 9 and the slider 8, the screw connection can be disengaged, making it convenient to remove the connecting protection shaft 9 when it has reached its maximum use level for replacement.

[0030] In this embodiment, when marking urban planning land using the device, the upper pile body 1 is first rotated so that the indicator block 10 on the outside of the upper pile body 1 is aligned with the indicator block 10 on the outside of the lower pile body 2. Then, the threaded shaft 7 is rotated and connected to the slider 8. The slider 8 is then controlled to drive the connecting protection shaft 9, which passes through the upper pile body 1, to continue passing through the lower pile body 2. Then, with the help of the spiral blade 3, the device is screwed into the ground by external large machinery. During the process of screwing the device into the ground, if the underground soil freezes, causing the device to be subjected to a torque exceeding its own strength limit, the reusable connecting protection shaft 9 will break to protect the device. The upper pile body 1 will continuously rotate with the rotating block 5 at the top of the lower pile body 2. When the torque monitoring device on the external screwing device detects the device... When the torque decreases sharply when screwed into the ground, the device can be removed. After removing the device from the ground, the threaded shaft 7 is screwed to the slider 8 by aligning the indicator block 10 on the outside of the upper pile body 1 with the indicator block 10 on the outside of the lower pile body 2. This further controls the connecting protection shaft 9, which has broken at the bottom, to continue moving down and passing through the lower pile body 2 again, facilitating continued use of the device. When the connecting protection shaft 9 has broken multiple times and reached its maximum usability, the push block 14 pushes the locking block 13 to compress the spring 12 and disengage it from the upper pile body 1. Then, the slider 8 is removed from the upper pile body 1 by the fixing rod 6 and the threaded shaft 7. Next, the remaining part of the connecting protection shaft 9 is screwed off from the slider 8 by rotating it, facilitating the replacement of the connecting protection shaft 9 that has reached its maximum usability.
