Description

Technical Field

[0001] This utility model belongs to the technical field of road surveying, specifically relating to a foldable windproof marker for road surveying point cloud data acquisition. Background Technology

[0002] In recent years, road surveying has undoubtedly become a crucial cornerstone in the grand scheme and complex system of road engineering construction. This step not only carries the foundational work in the early stages of a project, but also provides accurate and comprehensive data support for subsequent design, construction, and long-term maintenance and management. Specifically, point cloud data acquisition, as one of the core technologies of road surveying, mainly uses advanced equipment such as laser scanners to quickly and efficiently scan the road and its surrounding environment, thereby acquiring massive and dense point datasets. These datasets not only contain detailed information about the road surface but also cover key elements such as surrounding terrain and buildings, providing indispensable reference data for all stages of road engineering. However, natural factors such as wind often adversely affect the accuracy and reliability of point cloud data acquisition. To effectively address this challenge and ensure that the acquired data meets high accuracy and reliability standards, the innovative tool of windproof markers has emerged. The design and application of windproof markers aim to reduce the interference of wind on scanning equipment through physical means, thereby ensuring the stability of the data acquisition process and the accuracy of the data, further improving the overall quality and efficiency of road surveying.

[0003] Currently, most windproof marker poles on the market adopt an integrated telescopic structure design. This structure makes the entire marker pole exceptionally large. During transportation, the data acquisition device on top of the windproof marker pole is often directly exposed to the external environment without any protective measures. However, this design not only makes the acquisition device extremely susceptible to damage from collisions, friction, and other external forces during transportation, but also, due to its large size and exposed device, it brings great inconvenience to transportation, carrying, and subsequent installation work, increasing the difficulty of operation and potential risks. Utility Model Content

[0004] The purpose of this invention is to provide a foldable windproof marker for road survey point cloud data acquisition, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable windproof signpost for road survey point cloud data acquisition includes protective components, including a windproof signpost body with a main pole inside. A protective groove is formed on the outer surface of the windproof signpost body, and a folding assembly is disposed between the inside of the protective groove and the outer surface of the main pole. A limit assembly is disposed between the outer surface of the windproof signpost body and the outer surface of the main pole. A fixing component includes a clamping assembly disposed inside the protective groove for further fixing the main pole.

[0007] In a preferred embodiment of this utility model, the folding assembly includes a U-shaped plate, the outer surface of the main rod is rotatably connected to the middle of the U-shaped plate, a spring is symmetrically fixedly connected to the inner wall of the U-shaped plate, the end of the spring away from the U-shaped plate is fixedly connected to the outer surface of the main rod, a pull plate is symmetrically fixedly connected to the outer surface of the U-shaped plate, a first groove is provided on the inner wall of the protective groove, a first spring is fixedly connected inside the first groove, and the end of the first spring away from the first groove is fixedly connected to the outer surface of the U-shaped plate.

[0008] In a preferred embodiment of this utility model, the limiting component includes a limiting rod, a fixing plate is fixedly connected to the outer surface of the main rod, the top end of the limiting rod is fixedly connected to the middle part of the fixing plate, and a limiting groove is formed on the outer surface of the windproof signpost body, the inside of the limiting groove corresponds to the bottom end of the limiting rod.

[0009] As a preferred embodiment of this utility model, the outer surface of the windproof signpost body is symmetrically provided with through grooves, and the outer surface of the through grooves is slidably connected to the outer surface of the pull plate.

[0010] In a preferred embodiment of this utility model, the clamping assembly includes a pressing rod, an H-shaped groove is provided on the inner wall of the protective groove, the outer surface of the pressing rod is slidably connected to the inside of the H-shaped groove, a trapezoidal slider is symmetrically slidably connected to the inside of the H-shaped groove, an L-shaped clamping plate is fixedly connected to the outer surface of the trapezoidal slider, and the outer end of the pressing rod is fixedly connected to the outer surface of the U-shaped plate.

[0011] In a preferred embodiment of this utility model, a second spring is fixedly connected to the outer end of the trapezoidal slider. The second spring is located inside the H-shaped groove, and both ends of the second spring are fixedly connected to the outer ends of the trapezoidal sliders on both sides.

[0012] In a preferred embodiment of this invention, the inclined end face of the extrusion rod corresponds to the inclined end face of the trapezoidal slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up folding and limiting components, pulling the pull plate causes the U-shaped plate to slide inside the first slide groove. The first spring is stressed and generates elastic force, at which point the spring is released, causing the main rod to unfold outward. Then, the pull plate is released, and under the action of the first spring, the limiting rod is locked into the limiting groove, thus fixing the main rod. This allows the main rod to be folded and stored inside the protective groove, effectively reducing the overall volume and facilitating transportation and carrying. At the same time, the limiting components ensure that the main rod is securely limited after unfolding.

[0015] 2. By setting up a clamping assembly, the U-shaped plate slides inside the first slide groove, which in turn drives the compression rod to slide inside the H-shaped slide groove. The inclined end face of the compression rod contacts the inclined end face of the trapezoidal slider and generates compression. This causes the trapezoidal slider to slide inside the H-shaped slide groove and drive the L-shaped clamping plate to move closer to the main rod until the main rod is tightly clamped. As a result, the main rod can be further securely clamped after folding and storage, preventing shaking or displacement during transportation and further improving the safety and stability of the transportation process.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a foldable windproof signpost for road survey point cloud data acquisition, including protective components, including a windproof signpost body 10, a main pole 11 disposed inside the windproof signpost body 10, a protective groove 12 formed on the outer surface of the windproof signpost body 10, a folding assembly 13 disposed between the inside of the protective groove 12 and the outer surface of the main pole 11, and a limiting assembly 14 disposed between the outer surface of the windproof signpost body 10 and the outer surface of the main pole 11.

[0026] Specifically, the folding assembly 13 includes a U-shaped plate 131. The outer surface of the main rod 11 is rotatably connected to the middle of the U-shaped plate 131. A spring-loaded spring 132 is symmetrically fixedly connected to the inner wall of the U-shaped plate 131. The end of the spring-loaded spring 132 away from the U-shaped plate 131 is fixedly connected to the outer surface of the main rod 11. A pull plate 133 is symmetrically fixedly connected to the outer surface of the U-shaped plate 131. A first sliding groove 134 is formed on the inner wall of the protective groove 12. A first spring 135 is fixedly connected inside the first sliding groove 134. The end of the first spring 135 away from the first sliding groove 134 is fixedly connected to the outer surface of the U-shaped plate 131.

[0027] Furthermore, the limiting component 14 includes a limiting rod 141, a fixing plate 142 is fixedly connected to the outer surface of the main rod 11, the top of the limiting rod 141 is fixedly connected to the middle of the fixing plate 142, and a limiting groove 143 is opened on the outer surface of the windproof signpost body 10, the inside of the limiting groove 143 corresponds to the bottom end of the limiting rod 141.

[0028] The folding component 13 allows the main rod 11 to be folded and stored inside the protective groove 12, effectively reducing the overall volume and facilitating transportation and carrying. Users can pull the pull plate 133 to slide the U-shaped plate 131 inside the first slide groove 134. The first spring 135 is subjected to force and generates elasticity. At this time, the spring spring 132 is released, causing the main rod 11 to unfold outward. The limiting component 14 ensures that the main rod 11 is stably limited after unfolding, preventing it from shaking under the action of external forces such as wind, thus ensuring the accuracy and stability of data acquisition. When the pull plate 133 is released, the limiting rod 141 is inserted into the limiting groove 143 under the elasticity of the first spring 135, thereby fixing the main rod 11.

[0029] Preferably, the outer surface of the windproof signpost body 10 is symmetrically provided with through grooves 15, and the outer surface of the through grooves 15 is slidably connected to the outer surface of the pull plate 133.

[0030] It should be noted that by setting the through slide 15, the pulling plate 133 can slide inside the through slide 15, thereby driving the U-shaped plate 131 to move inside the protective groove 12, which can further fold or unfold the main rod 11.

[0031] In use, when the main rod 11 needs to be folded and stored, the operator can pull the pull plate 133 upwards. The upward movement of the pull plate 133 causes the U-shaped plate 131 to slide inside the first slide groove 134. The sliding of the U-shaped plate 131 applies tension to the first spring 135, causing the spring 135 to stretch and generate elasticity. Simultaneously, the upward movement of the U-shaped plate 131 causes the fixing plate 142 to move upwards, pulling the limiting rod 141 out of the limiting groove 143. Then, the main rod 11 is manually rotated. As the main rod 11 rotates inside the U-shaped plate 131, it winds and stores the spring 132 until the main rod 11 is completely folded and stored inside the protective groove 12. At this point, the spring 132 is in a stored state. Then, the pull plate 133 is released. Under the elastic force of the first spring 135, the U-shaped plate 131 automatically resets. The U-shaped plate 131 drives the collection device on the top of the main rod 11 into the protective groove 12, thus completing the folding and storage operation. When the main rod 11 needs to be unfolded for use, the operator only needs to pull the pull plate 133 again. The pull plate 133 drives the U-shaped plate 131 to slide in the first slide groove 134. At this time, the first spring 135 is stretched again by the tension to generate elastic force. At the same time, the clock spring 132 releases its stored force, causing the main rod 11 to flip outward. Then, the pull plate 133 is released. Under the elastic force of the first spring 135, the U-shaped plate 131 drives the fixing plate 142 to move down until the limiting rod 141 moves down into the limiting groove 143, realizing the stable limiting of the main rod 11, thus completing the unfolding operation.

[0032] Example 2

[0033] Reference Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a foldable windproof marker for road survey point cloud data acquisition. It includes a fixing component, including a clamping assembly 20 disposed inside the protective groove 12. The clamping assembly 20 is used to further fix the main pole body 11. The clamping assembly 20 includes a pressing rod 201. An H-shaped groove 202 is provided on the inner wall of the protective groove 12. The outer surface of the pressing rod 201 is slidably connected to the inside of the H-shaped groove 202. A trapezoidal slider 203 is symmetrically slidably connected inside the H-shaped groove 202. An L-shaped clamping plate 204 is fixedly connected to the outer surface of the trapezoidal slider 203. The outer end of the pressing rod 201 is fixedly connected to the outer surface of the U-shaped plate 131. A second spring 21 is fixedly connected to the outer end of the trapezoidal slider 203. The second spring 21 is located inside the H-shaped groove 202. The two ends of the second spring 21 are respectively fixedly connected to the outer ends of the trapezoidal sliders 203 on both sides. The inclined end face of the pressing rod 201 corresponds to the inclined end face of the trapezoidal slider 203.

[0034] The clamping component 20 allows the main rod 11 to be securely clamped after folding and storage, preventing it from shaking or shifting during transportation. The U-shaped plate 131 slides inside the first slide groove 134, which causes the compression rod 201 to slide inside the H-shaped slide groove 202. Its inclined end face contacts the inclined end face of the trapezoidal slider 203 and generates compression, causing the trapezoidal slider 203 to slide inside the H-shaped slide groove 202 and drive the L-shaped clamping plate 204 to move closer to the main rod 11 until the main rod 11 is tightly clamped.

[0035] When folding and storing, when the pull plate 133 is released, the U-shaped plate 131 will automatically return to its original position under the elastic force of the first spring 135. The U-shaped plate 131 drives the pressing rod 201 to slide in the H-shaped groove 202. At this time, the inclined end face of the pressing rod 201 and the inclined end face of the trapezoidal slider 203 press against each other. As the trapezoidal slider 203 is pressed, it will slide along the H-shaped groove 202 towards the center. The sliding of the trapezoidal slider 203 drives the L-shaped clamping plate 204 to move closer to the main rod 11 until the inner wall of the L-shaped clamping plate 204 is tightly attached to the outer surface of the main rod 11, thereby achieving further stable clamping of the main rod 11. During this process, the second spring 21 will be compressed by the pressing force of the trapezoidal slider 203 to generate elastic force.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
