Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for engineering machinery, and in particular to an electronic fence for cranes. Background Technology

[0002] With the acceleration of urbanization, the demand for high-rise buildings and large-scale infrastructure construction has surged. As the core equipment of heavy engineering machinery, cranes have attracted much attention for their operational safety. Electronic fences, through intelligent sensing and boundary control technologies, have become a key technical support for the safe operation of cranes.

[0003] Most existing technologies use GPS single-point positioning electronic fences. The core of this technology is to use GPS single-point positioning, input latitude and longitude coordinates in the background, set static electronic fence boundaries such as circles, rectangles, and polygons, and receive positioning data uploaded by the terminal in real time in the control console. The coordinates are calculated with the preset boundary to determine whether the crane has crossed the boundary.

[0004] Regarding the aforementioned technologies, the GPS single-point positioning electronic fence solution relies on preset latitude and longitude boundary coordinates for its monitoring range. Once set, it is difficult to adjust. In practical applications, risks are often dynamic, and GPS single-point positioning electronic fences cannot adapt to dynamically changing risk scenarios or meet differentiated operational needs, resulting in inconvenience in using electronic fences. Utility Model Content

[0005] To improve the ease of use of electronic fences, this application provides a crane electronic fence.

[0006] This application provides an electronic fence for cranes, employing the following technical solution: An electronic fence for a crane includes a main body with two telescopic sleeves on one side. The telescopic sleeves are detachably connected to the main body and are arranged laterally and placed parallel to each other. Satellite receiving antennas are provided at both ends of the main body. A movable rod is fixed at one end of each satellite receiving antenna. The movable rod corresponds to a telescopic sleeve and is inserted into the telescopic sleeve. The movable rod is slidably connected to the telescopic sleeve along its length. Two signal transmission antennas are provided at the upper end of the main body. During operation, the signal transmission antennas send electronic fence status information to the control console.

[0007] By adopting the above technical solution, two satellite receiving antennas are used to receive satellite signals to locate the status of the electronic fence. After the location is completed, the signal transmission antenna transmits the information of the electronic fence to the control console. The telescopic sleeve is detachably connected to the main body, which facilitates the installation, disassembly and maintenance of the equipment. The moving rod slides along the length of the telescopic sleeve, which drives the position of the satellite receiving antenna to change, thereby realizing the adjustment of the monitoring range, meeting the dynamic changes of risk scenarios, and improving the convenience of using the electronic fence.

[0008] Optionally, two telescopic rods are fixed at the lower end of the main body, with the two telescopic rods located at both ends of the main body, and the telescopic rods can be extended and retracted.

[0009] By adopting the above technical solution, the telescopic pole supports the main body, reducing the risk of overheating caused by the main body being too close to the ground during use. The telescopic pole can be extended and retracted, allowing for flexible adjustment of the height and position of the main body according to the actual usage scenario, thus improving the flexibility of using the electronic fence.

[0010] Optionally, the telescopic rod includes a support rod, a slide rod, and a tensioning element. The slide rod is located at the lower end of the main body, and the support rod is located at the end of the slide rod away from the main body. The slide rod is inserted into the support rod and is slidably connected to the support rod vertically. The tensioning element is located at the end of the support rod near the slide rod and is threadedly connected to the support rod. When the slide rod is positioned, the tensioning element cooperates with the support rod to lock the slide rod.

[0011] By adopting the above technical solution, when adjusting the length, loosening the tensioning component eliminates the clamping force generated by the threaded engagement, allowing the slide bar to slide freely. After adjusting the length, tightening the tensioning component causes the threaded engagement to rotate, squeezing the tensioning component towards the slide bar and engaging with the support rod to lock the slide bar. The locking force restricts the slide bar's movement, reducing the probability of the main body shaking or height deviation caused by slide bar displacement during use, thus improving the stability of the electronic fence.

[0012] Optionally, anti-slip stripes are fixed on the outside of the tensioner. When the tensioner is rotated, the anti-slip stripes are used to increase the friction between the hand and the tensioner.

[0013] By adopting the above technical solution, the anti-slip stripes form a biting point with the palm and fingers through the raised texture structure, so that the tightening parts can be easily turned without excessive force. Whether loosening to adjust the length of the slide bar or tightening to fix the slide bar, the operation is more effortless and smooth, improving the convenience of using the electronic fence.

[0014] Optionally, fixed blocks are fixed at both ends of the main body, the fixed blocks are rotatably connected to the slide rod, and a tension spring is fixed between the fixed blocks and the slide rod.

[0015] By adopting the above technical solution, the tension spring exerts a pulling force on the slide rod, ensuring that the slide rod and the sliding surface of the main body remain stably fitted. This counteracts the swaying space caused by the gap and provides elastic support for the slide rod, reducing vibration and swaying during the sliding process and improving the stability and reliability of the crane electronic fence. The fixing block is rotatably connected to the slide rod. After the electronic fence is used, the slide rod is rotated to make the telescopic rod vertically upward, realizing the folding of the equipment and facilitating its storage.

[0016] Optionally, a number of bolts are provided on one side of the telescopic sleeve, and the bolts are evenly distributed around the telescopic sleeve. The bolts pass through the telescopic sleeve and are threadedly connected to the main body.

[0017] By adopting the above technical solution, the preload of the threaded connection and bolts can effectively resist vibration or impact during equipment operation, reducing the risk of bolt loosening caused by vibration. At the same time, the threaded connection is a detachable connection method, which allows the telescopic sleeve to be easily removed from the main body and then reinstalled when the equipment is maintained, upgraded or replaced, improving the convenience of the device.

[0018] Optionally, a heat dissipation aluminum block is provided on the side of the main body away from the telescopic sleeve. When the main body generates heat during operation, the heat dissipation aluminum block dissipates heat from the main body.

[0019] By adopting the above technical solution, and utilizing the high thermal conductivity and large-area heat dissipation design of the heat sink aluminum block, efficient cooling of the main unit is achieved. This ensures the stable operation and extended lifespan of the internal components, reduces the risk of burns to users, and supports continuous operation of the equipment under high-load conditions. The heat sink aluminum block prioritizes heat conduction to itself and dissipates it quickly, ensuring the safety of equipment use.

[0020] Optionally, a warning light bulb is provided on the upper part of the main body. When the crane approaches the motor enclosure, the warning light bulb will light up red to warn the operator.

[0021] By adopting the above technical solution, when the crane approaches the electronic fence, the warning light bulb can promptly remind the operator by flashing a red light, reducing the operator's blind spots and delayed risk perception problems, and improving operational safety.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The movable pole slides along the length of the telescopic sleeve, causing the position of the satellite receiving antenna to change, thereby adjusting the monitoring range to meet the dynamic changes of risk scenarios and improve the convenience of using the electronic fence; 2. The rotation of the thread causes the tensioning element to press towards the slide bar, which cooperates with the support rod to lock the slide bar. The locking force restricts the sliding of the slide bar, reducing the probability of the main body shaking and height deviation caused by the displacement of the slide bar during use, and improving the stability of the electronic fence. 3. When the crane approaches the electronic fence, the warning light bulb can illuminate red to promptly remind the operator, reducing blind spots and delayed risk perception for the operator and improving operational safety.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] This application discloses an electronic fence for cranes. Example

[0028] Reference Figure 1 and Figure 2 An electronic fence for a crane includes a main body 1. Two telescopic sleeves 11 are provided on one side of the main body 1, arranged laterally and parallel to each other. Several bolts 114 are provided on one side of each telescopic sleeve 11, evenly distributed around the sleeve. The bolts 114 pass through the telescopic sleeves 11 and are threadedly connected to the main body 1. The threaded connection, combined with the preload of the bolts 114, effectively resists vibration or impact during equipment operation, reducing the risk of bolt loosening due to vibration and improving the stability of the device. The evenly distributed bolts 114 design makes the installation and disassembly of the telescopic sleeves 11 more standardized and regulated. Operators can tighten or loosen the bolts 114 sequentially according to a certain order, without complex positioning or adjustment, thus improving work efficiency.

[0029] Reference Figure 2 The telescopic sleeve 11 is equipped with a movable rod 111, which is slidably connected to the telescopic sleeve 11 along its length. Both ends of the main body 1 are equipped with satellite receiving antennas 112, which are fixed to the end of the movable rod 111 away from the telescopic sleeve 11. The satellite receiving antenna 112 adopts RTK module positioning technology and forms an electronic monitoring barrier through multiple electronic fences. The coordinates are stable over a long period of time and accurately calibrate the coordinates of the safety boundary. When it is necessary to adjust the monitoring range, the movable rod 111 is slid laterally. The movement of the movable rod 111 moves the satellite receiving antenna 112, thereby changing the position of the satellite receiving antenna 112 and adjusting the monitoring range to meet the dynamic changes of risk scenarios and improve the convenience of using the electronic fence.

[0030] Reference Figure 1The upper part of the main body 1 is provided with two signal transmission antennas 113 and two satellite receiving antennas 112 for receiving satellite signals to locate the electronic fence status. After the positioning is completed, the signal transmission antennas 113 use LoRa to receive differential data broadcast by the base station and send fence status information to the control console.

[0031] Reference Figure 1 The upper part of the main body 1 is equipped with a switch 16. When in use, simply turn on the switch 16. The entire structure is waterproof, ensuring normal use of the electronic fence in rainy weather. The lower part of the main body 1 is equipped with two telescopic rods 12, which are located at both ends of the main body 1. The telescopic rods 12 support the main body 1, reducing the ground heat caused by the main body 1 being too close to the ground during use, thus preventing the main body 1 from overheating.

[0032] Reference Figure 1 and Figure 2 The telescopic rod 12 includes a support rod 121, a slide rod 122, and a tensioning element 123. The slide rod 122 is fixed to the lower end of the main body 1. The support rod 121 is located at the end of the slide rod 122 away from the main body 1. The slide rod 122 is inserted into the support rod 121 and is slidably connected to the support rod 121 vertically to adjust the length of the telescopic rod 12. The tensioning element 123 is located at the end of the support rod 121 near the slide rod 122. The tensioning element 123 is threadedly connected to the support rod 121. When adjusting the length, the tensioning element 123 is loosened, and the clamping force generated by the threaded engagement... The slide bar 122 can slide freely after the length is adjusted. Tighten the tensioning element 123. The screw rotation causes the tensioning element 123 to press towards the slide bar 122, which cooperates with the support rod 121 to lock the slide bar 122. The locking force restricts the sliding of the slide bar 122, reducing the probability of the main body 1 shaking or height deviation caused by the displacement of the slide bar 122 during use, thus improving the stability of the electronic fence. The change in the length of the telescopic rod 12 realizes the change in the height of the main body 1. The height and position of the main body 1 can be flexibly adjusted according to the actual use scenario, improving the flexibility of the electronic fence.

[0033] Reference Figure 1 The outer side of the tensioning component 123 is provided with anti-slip stripes 124. When the tensioning component 123 is rotated, the anti-slip stripes 124 form a biting point with the palm and fingers through the raised texture structure. The tensioning component 123 can be easily turned without excessive force. Whether loosening the adjustment slide bar 122 or tightening the fixed slide bar 122, the operation is more effortless and smooth, improving the convenience of using the electronic fence.

[0034] Reference Figure 1A heat dissipation aluminum block 14 is provided on the side of the main body 1 away from the telescopic sleeve 11. When the main body 1 generates heat during operation, the high thermal conductivity and large-area heat dissipation design of the heat dissipation aluminum block 14 achieves efficient cooling of the main body 1. This not only ensures the stable operation and extends the life of the internal components of the main body 1, but also reduces the safety risk of burns to users, and supports continuous operation of the equipment under high-load scenarios. The heat dissipation aluminum block 14 prioritizes heat conduction to itself and dissipates it quickly, ensuring the safety of equipment use.

[0035] Reference Figure 1 The upper part of the main body 1 is equipped with a warning light bulb 15. When the crane approaches the motor fence, the warning light bulb 15 can light up red to remind the operator in a timely manner, reducing the operator's blind spots and delayed risk perception problems, and improving operational safety.

[0036] Reference Figure 1 and Figure 2 Fixed blocks 13 are fixed at both ends of the main body 1. The fixed blocks 13 are rotatably connected to the sliding rod 122. After the electronic fence is used, the sliding rod 122 is rotated to make the telescopic rod 12 vertically upward, realizing the folding of the equipment for easy storage. A tension spring 131 is fixed between the fixed blocks 13 and the sliding rod 122. The tension spring 131 exerts a tension force on the sliding rod 122, keeping the sliding rod 122 in stable contact with the sliding surface of the main body 1. It also provides elastic support to the sliding rod 122 to counteract the swaying space caused by the gap, reducing the vibration and swaying of the sliding rod 122 during the sliding process, and improving the stability and reliability of the crane electronic fence.

[0037] The implementation principle of the crane electronic fence in this application embodiment is as follows: when the switch 16 is turned on, the main body 1 is started. The satellite receiving antenna 112 uses RTK module positioning technology to locate the crane and monitor the crane's movement range. After the positioning is completed, the signal transmission antenna 113 transmits the electronic fence information to the control console. The horizontal sliding rod 111 moves, and the movement of the moving rod 111 causes the satellite receiving antenna 112 to move accordingly, thereby realizing the adjustment of the monitoring range, meeting the dynamic changes of risk scenarios, and improving the convenience of using the electronic fence.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
