Description

Technical Field

[0001] This utility model belongs to the field of land surveying collision avoidance technology, specifically a land surveying marker positioning structure. Background Technology

[0002] Land surveying marker positioning structure is a special structural device used in land surveying operations to accurately mark the location of measurement points and transmit measurement benchmark information. Its core function is to ensure the stability, visibility and repeatability of measurement points, and to provide reliable spatial reference for subsequent surveying data collection, engineering construction layout, land ownership delimitation and other work.

[0003] Existing land surveying marker structures mostly use simple steel nails, concrete piles, or wooden poles, which have many shortcomings. First, the structure has poor stability and is prone to settlement and tilting in loose soil layers or complex terrain. It is also easily damaged by external forces such as vehicle crushing or human collisions. Second, the positioning markers have limited functions, relying only on simple engraving or coloring, which not only makes it difficult to identify quickly but also fails to achieve accurate remote positioning, increasing the difficulty of on-site operations for surveyors. Third, they lack effective protective structures. In busy traffic areas or construction sites, the marker structures are easily damaged by impacts, causing the surveying benchmark to become invalid. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a land surveying and marking positioning structure, which has the advantages of adding anti-collision devices to the surface of the positioning device to avoid damage to the positioning device from impacts, and adopting a modular assembly method for the anti-collision devices to reduce the overall replacement cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a land surveying and marking positioning structure, comprising a positioning device and a base at the bottom for supporting the positioning device, characterized in that: a clamp is sleeved on the outer side of the positioning device, a transverse groove is formed on one side of the clamp near the impact end, a vertically arranged elastic strip is embedded inside the transverse groove of the clamp, the elastic strip is set in an arc shape, and U-shaped strips are fixedly pressed against both sides of the elastic strip, the arc directions of the U-shaped strip and the elastic strip are opposite, L-shaped frames are respectively on the upper and lower sides of the U-shaped frame, and guide rings rotate inside the two sets of L-shaped frames, the surface of the guide rings having an information indicating device.

[0006] Preferably, a collar is fixedly connected to both sides of the front end of the U-shaped strip, a U-shaped frame slides inside the collar, a threaded groove is opened on the surface of the collar, and a locking pin is threadedly connected in the threaded groove of the collar, the locking pin passes through and abuts against the surface of the U-shaped frame.

[0007] Preferably, the U-shaped frame has a rotatable support frame on its outer side, and the top of the support frame is provided with a vertical groove with an opening facing the guide ring. The square groove of the support frame fits in place, and the top of the U-shaped frame is respectively threaded through rubber blocks. The support frame is connected to a support plate by threads.

[0008] Preferably, the two ends of the support plate are U-shaped, and a buffer pad is fixedly connected in the U-shape.

[0009] Preferably, the U-shaped frame rotates on the outside of the support frame, and the U-shaped frame is configured as an inverted U-shape.

[0010] Preferably, one end of the U-shaped frame is attached to the rubber block and located on the vertical groove at the top of the support frame.

[0011] Preferably, both the U-shaped strip and the elastic strip are made of elastic material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adds a protective device to the outside of the positioning device to prevent the vehicle from crashing into the positioning device and causing damage. It also adds a device inside the U-shaped frame to guide the vehicle, which not only guides the vehicle but also guides it to a safe position in the event of a collision, preventing the vehicle from directly hitting the U-shaped frame and causing excessive stress on it. The U-shaped frame and support plate are designed to be detachable, so when the U-shaped frame or support plate is damaged, only the support plate or U-shaped frame needs to be replaced, without replacing the entire frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a land surveying and marking positioning structure, including a positioning device 12 and a base 13 at the bottom for supporting the positioning device 12. A clamp 10 is fitted on the outside of the positioning device 12. A transverse groove is formed on one side of the clamp 10 near the impact end. A vertically arranged elastic strip 9 is embedded in the transverse groove of the clamp 10. The elastic strip 9 is arc-shaped. U-shaped strips 8 are fixedly pressed against both sides of the elastic strip 9. The arc-shaped U-shaped strips 8 and the elastic strip 9 are in opposite directions. L-shaped... The frame 6 has two sets of L-shaped frames with internal rotating guide rings 7. The surface of the guide rings 7 has an information indicator device for guiding the vehicle. When the vehicle loses control, it will hit the guide rings 7. The guide rings 7 guide the vehicle to deflect, dispersing the impact force and avoiding direct impact with the positioning device 12. A device for protecting the positioning device 12 is added to the surface of the positioning device 12. The guide rings 7 are pushed by force to push the L-shaped frames 6 towards the U-shaped strip 8 to impact. The U-shaped strip 8 compresses the elastic strip 9 to produce deformation, which is used to weaken the impact force.

[0018] Specifically, two collars 4 are fixedly connected to the front ends of the U-shaped strip 8. A U-shaped frame 3 slides inside the collar 4. A threaded groove is opened on the surface of the collar 4. A locking pin 5 is threadedly connected in the threaded groove of the collar 4. The locking pin 5 passes through the collar 4 and abuts against the surface of the U-shaped frame 3. The two sets of collars 4 are located on the front ends of the U-shaped strip 8 respectively, and are used to support the U-shaped strip 8.

[0019] Furthermore, a support frame 2 is rotatably mounted on the outside of the U-shaped frame 3. The top of the support frame 2 is provided with a vertical groove with an opening facing the guide ring 7. The rubber block 14 of the support frame 2 is bolted through the top of the U-shaped frame 3. The support frame 2 is also threadedly connected to a support plate 1.

[0020] Furthermore, the two ends of the support plate 1 are set in a U-shape, and a buffer pad 11 is fixedly connected in the U-shape. When the force-bearing end of the support plate 1 is impacted by the outside, the force-bearing end of the support plate 1 will squeeze the buffer pad 11. The buffer pad 11 buffers the force-bearing end of the support plate 1 and avoids damage to the opposite position of the force-bearing end of the support plate 1.

[0021] It is worth noting that the U-shaped frame 3 rotates on the outside of the support frame 2, making the support frame 2 and the U-shaped frame 3 a detachable structure. This reduces the space occupied during transportation. Furthermore, if either the support frame 2 or the U-shaped frame 3 is damaged, only the support frame 2 or the U-shaped frame 3 needs to be replaced, without the need for a complete replacement, thus reducing replacement costs. The U-shaped frame 3 is designed as an inverted U-shape, and the entire U-shaped frame 3 has an arc transition, avoiding scratches to the vehicle from the traditional sharp ends.

[0022] It is worth noting that one end of the U-shaped frame 3 is attached to the rubber block 14 and located on the vertical groove at the top of the support frame 2. When the U-shaped frame 3 is impacted, the force of the U-shaped frame 3 is distributed to the upper and lower sides, transmitting the impact force to the rubber block 14. The rubber block 14 is used to buffer the U-shaped frame 3 and prevent the impact force from being directly transmitted to one end of the support frame 2.

[0023] It is worth mentioning that both the U-shaped strip 8 and the elastic strip 9 are made of elastic material. The U-shaped strip 8 is filled with a rigid strip to enhance the overall rigidity. Plastic material is added to the surface of the rigid strip to protect the internal rigid strip. When the U-shaped strip 8 is impacted, it can absorb some potential energy and reduce rebound. The U-shaped strip 8 is set with an arc facing the impact surface, which can increase the impact surface and enable multi-angle and all-round impact on the U-shaped strip 8.

[0024] The positioning device 12 and the base 13 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0025] Working principle: First, workers drill holes in the road surface, place the base 13 in the drilled hole, and fill the base 13 and the drilled hole with cement to fix the base 13. Then, the positioning device 12 is placed inside the base 13 and locked. The support plate 1 is installed on the cement block and fixed to the cement block with bolts. The support frame 2 is installed at the front end of the support plate 1. Finally, the U-shaped frame 3 is locked to the support plate 1 to fix the position of the drilled hole. When the vehicle goes out of control, the car hits the guide ring 7, the guide ring 7 rotates under force, and guides the vehicle to deviate. The guide ring 7 is pressed against the L-shaped frame 6, and the L-shaped frame 6 presses against the rear U-shaped strip 8. The U-shaped strip 8 with potential energy moves towards the elastic strip 9. During the movement, the elastic strip 9 weakens the potential energy of the U-shaped strip 8 and reduces the impact of the U-shaped strip 8. Simultaneously, the guide ring 7 is pressed against the L-shaped frame 6 at the front end of the U-shaped strip 8. The L-shaped frame 6, with a certain potential energy, presses the U-shaped frame 3 to move towards the support plate 1. The U-shaped frame 3 presses against the rubber block 14 at the top of the support frame 2. The rubber block 14 is used to buffer the U-shaped frame 3. The rubber block 14 presses the support frame 2 to move towards the support plate 1. The force-bearing end on one side of the support plate 1 presses against the buffer pad 11 inside the support plate 1 to buffer towards the interior of the other end of the support plate 1. During the buffering process, it is prevented that the U-shaped frame 3 is subjected to a large impact force, which would cause the U-shaped frame 3 to deviate towards the support plate 1. The U-shaped strip 8 loses control and impacts the clamp 10 on the surface of the positioning device 12, causing impact damage to the positioning device 12.
