Description

Technical Field

[0001] This application relates to the technical field of power grid construction, and in particular to a height restriction frame. Background Technology

[0002] At construction sites for overhead power lines, height restriction barriers are needed to limit the height of passing vehicles and prevent excessively tall vehicles from contacting or colliding with the overhead lines, thus creating safety hazards. However, height restriction barriers often cannot meet the temporary passage needs of vehicles that exceed the height limit.

[0003] In traditional technology, it is usually necessary to remove the height restriction frame to allow vehicles exceeding the height limit to pass temporarily. However, this method usually requires a lot of manpower to remove the height restriction frame, and after the vehicles pass, it is necessary to spend a lot of manpower to reinstall the height restriction frame in its original position, which is a cumbersome process. Utility Model Content

[0004] Therefore, it is necessary to provide a height restriction frame that addresses the problem of traditional technologies requiring a large amount of manpower to disassemble and assemble height restriction frames for temporary passage of vehicles exceeding the height limit, which leads to a cumbersome process.

[0005] The technical solution is as follows:

[0006] One embodiment provides a height restriction frame, including:

[0007] Installation mechanism, the installation mechanism being installed on the ground;

[0008] A telescopic mechanism, one end of which is disposed on the mounting mechanism; and,

[0009] A height limiting mechanism is provided at the end of the telescopic mechanism away from the installation mechanism. The telescopic mechanism can shorten or extend to bring the height limiting mechanism closer to or away from the ground.

[0010] The aforementioned height restriction frame has a telescopic mechanism with one end mounted on the ground, and the height restriction mechanism located at the end of the telescopic mechanism furthest from the mounting mechanism. The distance between the height restriction mechanism and the ground is the height limit imposed on vehicles by the height restriction frame. When a vehicle's height is less than the distance between the height restriction mechanism and the ground, the vehicle can pass smoothly underneath the height restriction mechanism. When a vehicle's height is greater than the distance between the height restriction mechanism and the ground, the vehicle cannot pass underneath the height restriction mechanism. When a vehicle with a height greater than the distance between the height restriction mechanism and the ground needs to temporarily pass under the height restriction frame, the operator extends the telescopic mechanism, increasing the distance between the height restriction mechanism and the ground, ensuring that the vehicle with temporary passage needs can pass normally underneath the height restriction mechanism. Subsequently, the operator shortens the telescopic mechanism to return the height restriction mechanism to its original position. Compared with traditional technology, the aforementioned height restriction frame, by adjusting the telescopic mechanism to extend or shorten, thereby adjusting the distance between the height restriction mechanism and the ground, allows vehicles with a height greater than the height limit imposed by the height restriction frame to temporarily pass under the height restriction frame, making the implementation process simple.

[0011] In one embodiment, the installation mechanism includes a first mounting base and a second mounting base, which are spaced apart on the ground along a first direction of the height restriction frame.

The innermost second sleeve is located on the second mounting base, and the outermost second sleeve is connected to the height restriction mechanism.

[0016] In one embodiment, the first mounting base includes a first mounting member with a first mounting groove. The end of the first telescopic module away from the height limiting mechanism is located in the first mounting groove, and the first telescopic module is capable of reciprocating along the depth direction of the first mounting groove. The second mounting base includes a second mounting member with a second mounting groove. The end of the second telescopic module away from the height limiting mechanism is located in the second mounting groove, and the second telescopic module is capable of reciprocating along the depth direction of the second mounting groove.

[0017] In one embodiment, the first mounting base further includes a first stabilizing plate, one side of which is disposed facing the ground and the other side of which is connected to the first mounting member. The second mounting base further includes a second stabilizing plate, one side of which is disposed facing the ground and the other side of which is connected to the second mounting member.

[0018] In one embodiment, the first stabilizing plate has at least two first extensions, all of which are spaced apart circumferentially along the first stabilizing plate. The first extensions are used to be disposed on the ground. The first mounting base also includes a first support member, one end of which is connected to any one of the first extensions, and the other end of which is connected to the first mounting member. The second stabilizing plate has at least two second extensions, all of which are spaced apart circumferentially along the second stabilizing plate. The second extensions are used to be disposed on the ground. The second mounting base also includes a second support member, one end of which is connected to any one of the second extensions, and the other end of which is connected to the second mounting member.

[0019] In one embodiment, the height limiting mechanism includes a third telescopic module, one end of which is located at the end of the first telescopic module away from the first mounting base, and the other end of which is located at the end of the second telescopic module away from the second mounting base.

[0020] In one embodiment, the third telescopic module includes a third sleeve, a fourth sleeve, and a fifth sleeve.

The audible and visual warning module is disposed on the telescopic mechanism, the height restriction mechanism, or the installation mechanism, and is electrically connected to the measurement module.

[0022] Specifically, when the width of the vehicle measured by the measurement module is greater than a preset width, the sound and light warning module emits a warning sound and light; when the height of the vehicle measured by the measurement module is greater than a preset height, the sound and light warning module emits a warning sound and light.

Detailed Implementation

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] Please see Figures 1 to 2 One embodiment of this application provides a height restriction frame, including an installation mechanism 100, a telescopic mechanism 200, and a height restriction mechanism 300. The installation mechanism 100 is installed on the ground; one end of the telescopic mechanism 200 is located on the installation mechanism 100; the height restriction mechanism 300 is located at the end of the telescopic mechanism 200 away from the installation mechanism 100. The telescopic mechanism 200 can shorten or extend to bring the height restriction mechanism 300 closer to or further away from the ground.

[0044] The aforementioned height restriction frame has one end of the telescopic mechanism 200 mounted on the installation mechanism 100 on the ground, and the height restriction mechanism 300 located at the end of the telescopic mechanism 200 furthest from the installation mechanism 100. The distance between the height restriction mechanism 300 and the ground is the height limit imposed on passing vehicles by the height restriction frame. When the height of a vehicle is less than the distance between the height restriction mechanism 300 and the ground, the vehicle can pass smoothly under the height restriction mechanism 300. When the height of a vehicle is greater than the distance between the height restriction mechanism 300 and the ground, the vehicle cannot pass under the height restriction mechanism 300. Vehicles with a height greater than the distance between the height restriction mechanism 300 and the ground have temporary... When a vehicle needs to pass under a height restriction barrier, the staff extends the telescopic mechanism 200, increasing the distance between the height restriction mechanism 300 and the ground, ensuring that vehicles with temporary passage needs can pass normally under the height restriction mechanism 300. Subsequently, the staff adjusts the telescopic mechanism 200 to shorten it, returning the height restriction mechanism 300 to its original position. Compared with traditional technology, the above-mentioned height restriction barrier, by adjusting the telescopic mechanism 200 to extend or shorten, thereby adjusting the distance between the height restriction mechanism 300 and the ground, allows vehicles with a height greater than the height limit of the height restriction barrier to temporarily pass through it, making the implementation process simple.

[0045] Optionally, the telescopic mechanism 200 can extend or retract via a scissor lift module or a telescopic rod, as long as it can move the height restriction mechanism 300 closer to or further away from the ground; no specific limitation is made here.

[0046] Furthermore, the height restriction mechanism 300 includes a height restriction bar, which is installed on the telescopic mechanism 200 and parallel to the ground. The distance between the height restriction bar and the ground is the height restriction of the height restriction frame.

[0047] Please see Figures 1 to 2 In one embodiment, the installation mechanism 100 includes a first mounting base 110 and a second mounting base 120, which are spaced apart on the ground along a first direction of the height restriction frame. The telescopic mechanism 200 includes a first telescopic module 210 and a second telescopic module 220, with one end of the first telescopic module 210 disposed on the first mounting base 110 and the other end of the first telescopic module 210 connected to the height restriction mechanism 300. One end of the second telescopic module 220 is disposed on the second mounting base 120 and the other end of the second telescopic module 220 is connected to the height restriction mechanism 300.

[0048] The first mounting base 110 and the second mounting base 120 are spaced apart on the ground along the first direction of the height restriction frame. The first telescopic module 210 and the second telescopic module 220 are respectively mounted on the first mounting base 110 and the second mounting base 120. The first telescopic module 210 and the second telescopic module 220 support the height restriction mechanism 300 and drive the height restriction mechanism 300 closer to or away from the ground. In this way, not only can the movement stability of the height restriction mechanism 300 when it is close to or away from the ground be improved, but also the overall installation stability of the height restriction frame can be improved.

[0049] For illustrative purposes, the first direction of the height restriction frame is the width direction of the height restriction frame (i.e., Figure 2 The G direction in the diagram refers to the width direction of vehicles passing through the height restriction barrier, which will not be elaborated here.

[0050] Understandably, the height restriction frame can also limit the width of passing vehicles. Specifically, the distance between the first mounting base 110 and the second mounting base 120 is the width restriction imposed on the vehicle by the height restriction frame.

[0051] Furthermore, the first mounting base 110, the first telescopic module 210, the height limiting mechanism 300, the second telescopic module 220, the second mounting base 120, and the ground enclosure form an opening for vehicles to pass through, the height and width of which are the height and width of vehicles restricted by the height limiting frame.

[0052] Please see Figure 2 and Figure 5 In one embodiment, the first telescopic module 210 includes at least two first sleeves 211, all of which are nested sequentially along the second direction of the height restriction frame, the second direction being perpendicular to the first direction. The outermost first sleeve 211 is located on the first mounting base 110, and the innermost first sleeve 211 is connected to the height restriction mechanism 300.

[0053] The first telescopic module 210 is extended or shortened by at least two nested first sleeves 211, which is low in implementation cost and reliable in telescopic process.

[0054] As an alternative embodiment to the above embodiments, the first telescopic module 210 includes at least two first sleeves 211. All the first sleeves 211 are nested sequentially along the second direction of the height-limiting frame, which is perpendicular to the first direction. The innermost first sleeve 211 is located on the first mounting base 110, and the outermost first sleeve 211 is connected to the height-limiting mechanism 300. In contrast to the above embodiments, in this embodiment, of the at least two nested first sleeves 211, the innermost first sleeve 211 is located on the first mounting base 110, and the outermost first sleeve 211 is connected to the height-limiting mechanism 300.

[0055] For illustrative purposes, the second direction in the above embodiments is the height direction of the height restriction frame (i.e., Figure 2 (in the H direction), which will not be elaborated here.

[0056] Optionally, the first tube 211 can be a circular tube, a square tube, or a tube of other polygons; no specific limitation is made here.

[0057] Specifically Figures 1 to 6 In the embodiment shown, the first sleeve 211 is a square tube.

[0058] Please see Figure 5 In one embodiment, the first sleeve 211 is provided with at least two first connecting through holes spaced apart along the second direction. When the first telescopic module 210 is telescopic, all the first sleeves 211 need to be adjusted to the appropriate position. Then, the connecting component is inserted into the first connecting through holes of two adjacent first sleeves 211 to fix the two adjacent first sleeves 211, thereby fixing the first telescopic module 210 as a whole.

[0059] Alternatively, the connecting components can be locating pins, locating bolts, etc., without specific limitations.

[0060] Furthermore, the outer diameter of the first sleeve 211 decreases sequentially, and the decreasing outer diameter is the difference between the wall thickness and tolerance of one of the two nested first sleeves 211.

[0061] Please see Figure 2In one embodiment, the second telescopic module 220 includes at least two second sleeves 221, all of which are nested sequentially along the second direction of the height restriction frame, the second direction being perpendicular to the first direction. The outermost second sleeve 221 is located on the second mounting base 120, and the innermost second sleeve 221 is connected to the height restriction mechanism 300.

[0062] As an alternative embodiment to the above embodiment, the second telescopic module 220 includes at least two second sleeves 221. All the second sleeves 221 are nested sequentially along the second direction of the height restriction frame. The second direction is perpendicular to the first direction. The innermost second sleeve 221 is located on the second mounting base 120, and the outermost second sleeve 221 is connected to the height restriction mechanism 300.

[0063] The second sleeve 221 of the second telescopic module 220 is similar to the first sleeve 211 of the first telescopic module 210, and will not be described again here.

[0064] Please see Figure 2 and Figure 3 In one embodiment, the first mounting base 110 includes a first mounting member 111, the first mounting member 111 having a first mounting groove 112, the end of the first telescopic module 210 away from the height limiting mechanism 300 being disposed in the first mounting groove 112, the first telescopic module 210 being capable of reciprocating along the depth direction of the first mounting groove 112, the second mounting base 120 includes a second mounting member, the second mounting member having a second mounting groove, the end of the second telescopic module 220 away from the height limiting mechanism 300 being disposed in the second mounting groove, the second telescopic module 220 being capable of reciprocating along the depth direction of the second mounting groove.

[0065] The end of the first telescopic module 210 furthest from the height-limiting mechanism 300 is located within the first mounting groove 112 of the first mounting member 111, and can reciprocate along the depth direction of the first mounting groove 112, thereby moving the height-limiting mechanism 300 closer to or away from the ground. Thus, the first telescopic module 210 can not only be stored in the first mounting groove 112 during transport of the height-limiting frame, serving a storage function, but it can also cooperate with the first telescopic module 210 to move the height-limiting mechanism 300 closer to or away from the ground. The second mounting member and the second telescopic module 220 are similar to the first mounting member 111 and the first telescopic module 210, and will not be described in detail here.

[0066] Furthermore, the first mounting member 111 is a tubular structure with a square cross-section, and the shape of the first mounting groove 112 matches the shape of the first sleeve 211 to accommodate the first sleeve 211. The second mounting member is similar to the first mounting member 111, and will not be described in detail here.

[0067] Please see Figure 3In one embodiment, the first mounting base 110 further includes a first stabilizing plate 113, one side of which is disposed facing the ground and the other side of which is connected to the first mounting member 111. The second mounting base 120 further includes a second stabilizing plate, one side of which is disposed facing the ground and the other side of which is connected to the second mounting member.

[0068] One side of the first stabilizing plate 113 faces the ground, and the other side is connected to the first mounting component 111. This increases the overall contact area between the first mounting base 110 and the ground, thereby ensuring the installation stability of the first mounting component 111 and preventing the entire height restriction frame from tipping over. The second stabilizing plate is similar to the first stabilizing plate 113, and will not be described in detail here.

[0069] Furthermore, the contact area between the first stabilizing plate 113 and the ground is greater than the installation area of ​​the first mounting member 111 and the first stabilizing plate 113. The first stabilizing plate 113 is laid flat on the ground, and the stability of the first mounting member 111 on the ground is improved by setting the first stabilizing plate 113.

[0070] Furthermore, the first stabilizing plate 113 has an assembly hole 114, and the first mounting member 111 is inserted into the assembly hole 114 to achieve the connection between the first mounting member 111 and the first stabilizing plate 113.

[0071] Furthermore, at least two triangular supports 115 are provided at the connection between the first stabilizing plate 113 and the first mounting member 111, thereby further improving the connection reliability between the first stabilizing plate 113 and the first mounting member 111.

[0072] The second stabilizing plate is similar to the first stabilizing plate 113, and will not be described again here.

[0073] Please see Figures 3 to 4 In one embodiment, the first stabilizing plate 113 is provided with at least two first extensions 116, all of which are spaced apart circumferentially along the first stabilizing plate 113. The first extensions 116 are used to be placed on the ground. The first mounting base 110 also includes a first support member 117, one end of which is connected to any one of the first extensions 116, and the other end of which is connected to the first mounting member 111. The second stabilizing plate is provided with at least two second extensions, all of which are spaced apart circumferentially along the second stabilizing plate. The second extensions are used to be placed on the ground. The second mounting base 120 also includes a second support member, one end of which is connected to any one of the second extensions, and the other end of which is connected to the second mounting member.

[0074] At least two first extensions 116 are axially spaced along the first stabilizing plate 113 and disposed on the ground, thereby further improving the stability of the first mounting base 110 on the ground without affecting vehicle passage. In addition, by providing the first support member 117, the first extensions 116 and the first mounting member 111 can be connected to provide stable support for the first mounting member 111 and improve the structural stability of the first mounting base 110. The second extension and the second support member are similar to the first extensions 116 and the first support member 117, and will not be described in detail here.

[0075] Please see Figure 3 In one embodiment, the end of the first support member 117 away from the first extension 116 is also provided with a connecting plate 118. The connecting plate 118 is connected to the first mounting member 111 through a threaded component to ensure the support effect of the first support member 117 on the first mounting member 111 and enhance the stability of the height restriction frame under the action of external force or wind.

[0076] Please see Figure 2 and Figure 3 In one embodiment, at least four first extensions 116 are provided, wherein two first extensions 116 extend in opposite directions along a first direction, and the other two first extensions 116 extend in opposite directions along a third direction, which is perpendicular to the first direction and perpendicular to the second direction.

[0077] Furthermore, the third direction is the direction of travel of the vehicle when passing through the height restriction barrier (i.e., Figure 2 (The I direction in the middle), which will not be elaborated here.

[0078] In one embodiment, the first extension 116 is provided with at least two fixing holes 119. When it is necessary to fix the first mounting base 110 to the ground, a triangular ground plug or expansion screw is used to pass through the fixing holes 119 and fix it to the ground to secure the first mounting base 110.

[0079] Furthermore, the triangular ground plug is mainly used to fix the first mounting base 110 to the unhardened dirt road, and the expansion bolt is mainly used to fix the first mounting base 110 to the hardened road.

[0080] The second extension is similar to the first extension 116, and will not be described again here.

[0081] Please see Figure 1 and Figure 2 In one embodiment, the height limiting mechanism 300 includes a third telescopic module 310, one end of which is located at the end of the first telescopic module 210 away from the first mounting base 110, and the other end of which is located at the end of the second telescopic module 220 away from the second mounting base 120.

[0082] With this configuration, when adjusting the installation positions of the first mounting base 110 and the second mounting base 120 on the ground, the third telescopic module 310 can extend or shorten synchronously to adapt to the distance between the first mounting base 110 and the second mounting base 120, thereby improving the applicability of the height restriction frame.

[0083] Furthermore, by adjusting the installation positions of the first mounting base 110 and the second mounting base 120 on the ground, as well as the distance between the first mounting base 110 and the second mounting base 120, the width of the vehicle that the height restriction frame can limit can be adjusted as needed, thereby improving the applicability of the height restriction frame.

[0084] Optionally, the third telescopic module 310 can be telescopic in the form of a scissor lift module or a telescopic rod; no specific limitation is made here.

[0085] Please see Figure 2 , Figure 8 and Figure 9 In one embodiment, the third telescopic module 310 includes a third sleeve 311, a fourth sleeve 312, and a fifth sleeve 313. One end of the third sleeve 311 is located at the end of the first telescopic module 210 away from the first mounting base 110. One end of the fourth sleeve 312 is located at the end of the second telescopic module 220 away from the second mounting base 120. One end of the fifth sleeve 313 is sleeved at the end of the third sleeve 311 away from the first telescopic module 210, and the other end of the fifth sleeve 313 is sleeved at the end of the fourth sleeve 312 away from the second telescopic module 220.

[0086] The fifth sleeve 313 is located between the third sleeve 311 and the fourth sleeve 312, and the opposite ends of the fifth sleeve 313 are respectively sleeved on the third sleeve 311 and the fourth sleeve 312 to realize the extension and retraction of the third telescopic module 310. This arrangement also enables the two ends of the fifth sleeve 313 to remain balanced, thereby ensuring the balance of the gravity of the first telescopic module 210 and the second telescopic module 220 on the two ends of the third telescopic module 310.

[0087] Optionally, one end of the fifth sleeve 313 can be fitted onto the outside of the third sleeve 311 or onto the inside of the third sleeve 311. Similarly, the other end of the fifth sleeve 313 can be fitted onto the outside of the fourth sleeve 312 or onto the inside of the fourth sleeve 312; no specific limitation is made here. Figure 2 In the embodiment shown, the opposite ends of the fifth sleeve 313 are respectively sleeved on the outside of the third sleeve 311 and the outside of the fourth sleeve 312.

[0088] Furthermore, the first sleeve 211, the second sleeve 221, the third sleeve 311, the fourth sleeve 312, and the fifth sleeve 313 are all made of aluminum alloy, which is lightweight, high-strength, and low-cost.

[0089] In one embodiment, the surfaces of the first sleeve 211, the second sleeve 221, the third sleeve 311, the fourth sleeve 312, and the fifth sleeve 313 are all sprayed with insulating varnish. The thickness of the insulating varnish is between 1 mm and 3 mm to ensure the insulation of the height restriction frame and to prevent electric shock accidents caused by short circuits in the power transmission cables due to the height restriction frame touching them.

[0090] Furthermore, a layer of reflective warning tape is sprayed onto the surface of the insulating paint to enhance the visibility and warning effect of the height restriction frame during the day and night.

[0091] Please see Figure 2 and Figure 7 In one embodiment, the height restriction frame further includes a connecting longitudinal rod 410 and a connecting horizontal rod 420. One end of the connecting longitudinal rod 410 is sleeved on the first sleeve 211, and the other end of the connecting longitudinal rod 410 is welded to the side wall of the connecting horizontal rod 420. The connecting horizontal rod 420 is sleeved on the third sleeve 311. The connection method between the second sleeve 221 and the fourth sleeve 312 is similar to that between the first sleeve 211 and the third sleeve 311, and will not be described again here.

[0092] Furthermore, the height restriction mechanism 300 is also equipped with a lightning rod 500 so that the height restriction frame has a grounding function to protect against lightning and electric shock.

[0093] Please see Figure 1 In one embodiment, the height restriction frame further includes a measurement module 600 and an audible and visual warning module. The measurement module 600 is disposed on the height restriction mechanism 300 and is used to measure the width and height of the vehicle. The audible and visual warning module is disposed on the telescopic mechanism 200, the height restriction mechanism 300, or the installation mechanism 100. The audible and visual warning module is electrically connected to the measurement module 600.

[0094] Specifically, when the width of the vehicle measured by the measurement module 600 is greater than the preset width, the audible and visual warning module emits a warning sound and light; when the height of the vehicle measured by the measurement module 600 is greater than the preset height, the audible and visual warning module emits a warning sound and light.

[0095] The measurement module 600 measures the height and width of the vehicle about to pass through the height restriction barrier. When at least one of the height and width of the vehicle measured by the measurement module 600 is greater than the preset height and preset width, the audible and visual warning module will emit a warning sound and light to remind the driver that the vehicle cannot pass through the height restriction barrier. This setting can prevent the vehicle from damaging the height restriction barrier.

[0096] Please see Figure 1 and Figure 10 In one embodiment, the height restriction frame also includes an intelligent monitoring mechanism 700, which includes a main control board 710, a camera module 720, a solar cell module 730, a multi-colored light strip 740, and the aforementioned measurement module 600.

[0097] Furthermore, the telescopic mechanism 200 is provided with a support platform 800, which includes a fixed sleeve 810 and a support plate 820. The fixed sleeve 810 is sleeved on the telescopic mechanism 200, and the support platform 800 is set on the fixed sleeve 810. The main control board 710, camera module 720, solar cell module 730 and multi-color light strip 740 are all set on the support plate 820 to facilitate the installation and disassembly of each module and to ensure reliable fixation.

[0098] The main control board 710, as the core control unit of the intelligent monitoring mechanism 700, is responsible for coordinating and managing the operation of various components within the module. It receives data from various sensors, analyzes and processes it, and issues corresponding control commands according to preset logic. For example, when it receives data from the measurement module 600 indicating that a vehicle is approaching a height restriction barrier or exceeding the height and width restrictions, the main control board 710 will trigger the audible and visual warning module and transmit the relevant information to the backend and cloud monitoring system.

[0099] The camera module 720 features high-definition image capture and accurate image recognition capabilities. It can capture images of passing vehicles in real time and accurately identify the vehicles and their license plates. The captured images and recognition results are recorded and simultaneously notified to relevant management personnel remotely via the network. This function helps to trace and manage vehicles that violate traffic rules, improving the efficiency and accuracy of traffic management.

[0100] The solar cell module 730 consists of a power controller, solar panels, and lithium batteries. The solar panels convert solar energy into electrical energy, while the power controller manages and regulates the electrical energy to ensure a stable power supply to all components within the module. The lithium batteries store excess energy to power the module at night or when sunlight is insufficient, ensuring the intelligent monitoring system 700 can operate continuously and stably, achieving energy self-sufficiency and reducing operating costs.

[0101] The multi-colored light strip 740 is fixed to the height restriction frame through standard mounting holes, primarily for providing a warning function at night or in low-light environments. The multi-colored light strip 740 is electrically connected to a solar panel module 730. During the day, the solar panel module 730 stores electrical energy; at night, when visibility is poor, it powers the multi-colored light strip 740, causing it to emit bright, multi-colored light, significantly improving the visibility of the height restriction frame. The flashing of different colored lights can attract the attention of drivers, reminding them of the height and width restrictions at the construction site, thereby effectively preventing vehicle collisions with the height restriction frame.

[0102] Please see Figure 1 and Figure 11 The measurement module 600 has two units installed at both ends of the height restriction mechanism 300. This module combines a horizontal scanning gimbal 610, an X-axis laser rangefinder 620, a longitudinal scanning gimbal 630, and a Z-axis laser rangefinder 640 to detect the height and width restrictions of passing vehicles.

[0103] The two sets of horizontal scanning gimbals 610 and X-axis laser rangefinders 620, mounted on the crossbars of the height restriction barrier, work together. The horizontal scanning gimbals 610 drive the X-axis laser rangefinders 620 to scan horizontally and measure the width of the vehicle in real time. When a vehicle is detected to exceed the width limit of the height restriction barrier, the system will immediately issue an audible and visual warning signal and transmit relevant information to the backend so that management personnel can take timely measures.

[0104] Similarly, the left and right sets of longitudinal scanning gimbals 630 and Z-axis laser rangefinders 640 are used to detect the height of the vehicle. The longitudinal scanning gimbals 630 drive the Z-axis laser rangefinders 640 to scan vertically. Once a vehicle is detected to exceed the height limit of the height restriction frame, an audible and visual warning will be triggered and the data will be uploaded to the backend.

[0105] The gimbal control board 650 communicates with the main control board 710. Based on the commands issued by the main control board 710, it precisely controls and operates the movement of the horizontal scanning gimbal 610 and the vertical scanning gimbal 630. Through flexible control of the gimbals, the laser rangefinder sensor can accurately scan and detect passing vehicles, improving the accuracy and reliability of the detection.

[0106] The intelligent monitoring unit 700 communicates with the cloud-based monitoring system via a 4G module, enabling remote monitoring and interaction. The cloud-based monitoring system can receive real-time data such as vehicle information and warning messages uploaded by the intelligent monitoring unit 700. Managers can remotely monitor and manage the operation of the height restriction barrier through the cloud platform. Simultaneously, the intelligent monitoring unit 700 can also receive instructions from the cloud-based monitoring system, adjusting its operating parameters and modes to adapt to different application scenarios and management needs.

[0107] In addition, the main control board 710 of the intelligent monitoring unit 700 is equipped with an ultrasonic ranging module to measure the distance between the vehicle and the height restriction barrier. When the vehicle approaches the height restriction barrier to a preset distance (e.g., 5m), the system will record the information and enhance the audible and visual warnings, further strengthening the safety protection capability of the height restriction barrier.

[0108] The workflow of the intelligent monitoring mechanism 700 is as follows: When a vehicle approaches the height restriction barrier, the camera module 720 first captures and identifies the vehicle, records its information, and uploads it to the backend. Simultaneously, the ultrasonic ranging module measures the distance between the vehicle and the height restriction barrier in real time. When the distance reaches a set warning value (e.g., 5m), an audible and visual warning system is triggered to alert the driver. The horizontal scanning pan-tilt unit 610, X-axis laser ranging sensor 620, vertical scanning pan-tilt unit 630, and Z-axis laser ranging sensor 640 in the laser scanning warning module begin operation, performing real-time scanning and monitoring of the vehicle's width and height. If the vehicle's width or height exceeds the limit, the pan-tilt control board 650, according to the instructions from the main control board 710, controls the audible and visual warning device to emit a strong audible and visual signal, alerting the driver and surrounding personnel. Simultaneously, the warning information is transmitted to the cloud monitoring system via the main control board 710 for remote monitoring and management. The solar cell module 730 continuously powers the entire intelligent monitoring mechanism 700, ensuring stable operation in various environments. The power controller intelligently manages energy distribution and storage based on the power generation of the solar panels and the state of charge of the lithium batteries, ensuring reliable operation of the system over long periods of time.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
