[0002] In the construction industry, building materials need to be transported by truck. However, when pouring concrete for high arch dams, the unloading platform is often located at a high edge, and the rear-discharge trucks may overturn due to the sudden unloading, posing a significant safety hazard. Utility Model Content

[0003] Therefore, it is necessary to provide an anti-tipping device to address the risk of overturning that is prone to occur during the unloading process of rear-discharge trucks.

[0008] When the car is mounted on the support platform and the first magnetic component is energized, the first magnetic component can generate a magnetic attraction force relative to the second magnetic component.

[0009] In some embodiments, the first magnetic attraction component includes:

[0010] First iron core;

[0011] A first coil is wound around the outer periphery of the first iron core; and both ends are used for connection to a power source; and

[0012] A magnetic top plate is connected to the side of the first iron core near the support platform;

[0013] When the first coil is energized, the magnetic top plate can generate magnetic attraction.

[0014] In some embodiments, the first magnetic component further includes a magnetic base plate;

[0015] The magnetic base plate is connected to the end of the first iron core away from the magnetic top plate.

[0016] In some embodiments, the first coil includes a winding portion and a lead portion connected to each other;

[0017] The winding portion is wound around the outer periphery of the first iron core;

[0018] The anti-tipping device also includes a protective sleeve; the protective sleeve is fitted onto the lead wire portion.

[0019] In some embodiments, the anti-tipping device further includes a receiving element;

[0020] The receiving member is configured with a receiving cavity for receiving one end of the lead portion away from the winding portion.

[0021] In some embodiments, the receiving element is configured with an opening;

[0022] The anti-tipping device also includes a cover plate; the cover plate is closable and connected to the opening.

[0023] In some embodiments, the second magnetic component includes:

[0024] The telescopic component, one end of which is used to connect to the vehicle chassis; and

[0025] A magnetic suction plate; connected to the end of the retractable member away from the vehicle chassis;

[0040] 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.

[0044] See Figure 1 , Figure 1 This diagram illustrates an anti-tipping device provided in some embodiments of this application that can prevent a vehicle 800 from tipping over. One embodiment of the anti-tipping device includes a support platform 100, a first magnetic attraction component 200, and a second magnetic attraction component 300. The first magnetic attraction component 200 is mounted on one side of the support platform 100 in the thickness direction; specifically, the thickness direction of the support platform 100 is... Figure 1 The direction of zz' in the middle; the second magnetic component 300 is used to connect with the car chassis 810; wherein, when the car 800 is carried on the support platform 100 and the first magnetic component 200 is energized, the first magnetic component 200 can generate a magnetic attraction force relative to the second magnetic component 300.

[0045] When the second magnetic suction component 300 of the aforementioned anti-tipping device is installed on the vehicle chassis 810, and the vehicle 800 moves to the support platform 100 for rear unloading, the first magnetic suction component 200 is energized, thereby generating a magnetic field and magnetic attraction force, which in turn magnetically attracts the second magnetic suction component 300. This results in the vehicle chassis 810 being subjected to a downward magnetic attraction force, making it less likely for the vehicle chassis 810 to tip over relative to the support platform 100. This makes the rear unloading vehicle 800 safer during unloading.

[0046] The following is a detailed description of the structure of the anti-tipping device. Please refer to [link / reference]. Figures 2-4 , Figure 2 It shows Figure 1 The top view shown. Figure 3 It shows Figure 1 A schematic diagram of the first magnetic suction component 200, protective sleeve 400, receiving component 500, and cover plate 600 in the anti-tipping device shown. Figure 4 It shows Figure 1 A schematic diagram of the second magnetic suction component 300 in the anti-tipping device shown.

[0047] Please see Figure 3 In some embodiments, the first magnetic attraction assembly 200 includes a first iron core 210, a first coil 220, and a magnetic attraction top plate 230. The first coil 220 is wound around the outer periphery of the first iron core 210, and its two ends are used for connection to a power source. The magnetic attraction top plate 230 is connected to the side of the first iron core 210 near the support platform 100. When the first coil 220 is energized, the magnetic attraction top plate 230 can generate a magnetic attraction force. When the first coil 220 of the first magnetic attraction assembly 200 is energized, it generates a magnetic field, which magnetizes the magnetic attraction top plate 230 and generates a magnetic attraction force on the second magnetic attraction assembly 300. Specifically, when the first coil 220 is energized, the magnetic properties of the magnetic attraction top plate 230 and the second magnetic attraction assembly 300 are opposite, thus generating a magnetic attraction force between them.

[0048] Please see Figure 3In some embodiments, the first magnetic traction assembly 200 further includes a magnetic base plate 240; the magnetic base plate 240 is connected to the end of the first iron core 210 away from the magnetic top plate 230. By setting the magnetic base plate 240, the magnetic top plate 230 and the magnetic base plate 240 can be arranged opposite each other along the extending direction of the first iron core 210, so that when the first coil 220 is energized, the magnetic field can be more effectively closed by the magnetic top plate 230 and the magnetic base plate 240, thereby reducing the leakage of magnetic flux, enhancing the magnetic field strength generated by the entire first magnetic traction assembly 200, and ultimately making the magnetic attraction force applied to the second magnetic traction assembly stronger, making the car 800 less likely to overturn.

[0049] Please see Figure 3 In some embodiments, the first coil 220 includes a winding portion 221 and a lead portion 222 connected to each other; the winding portion 221 is wound around the outer periphery of the first iron core 210; the anti-tipping device also includes a protective sleeve 400; the protective sleeve 400 is fitted onto the lead portion 222. By winding the first iron core 210 with the winding portion 221, a magnetic field can be generated together with the first iron core 210 when the first coil 220 is energized. By fitting the protective sleeve 400 onto the lead portion 222, the lead portion 222 can be protected by the protective sleeve 400, reducing the possibility of damage to it.

[0050] Please see Figure 1 and Figure 3 In some embodiments, the anti-tipping device further includes a receiving member 500; the receiving member 500 is configured with a receiving cavity 510 for receiving the end of the lead portion 222 away from the winding portion 221. By providing the receiving member 500 with the receiving cavity 510, the end of the lead portion 222 away from the winding portion 221 can be placed in the receiving cavity 510, thereby facilitating subsequent maintenance of the first coil 220.

[0051] Please see Figure 1 and Figure 3 In some embodiments, the receiving member 500 is configured with an opening; the anti-tipping device also includes a cover plate 600; the cover plate 600 is closable connected to the opening. By providing an opening in the receiving member 500 and making the cover plate 600 closable connected to the opening, it is convenient to open the cover plate 600 and the opening to perform maintenance operations on the first coil 220 when maintenance is required, and to close the cover plate 600 and the opening after the maintenance is completed.

[0052] Please see Figure 4In some embodiments, the second magnetic traction assembly 300 includes a retractable member 310 and a magnetic plate 320. One end of the retractable member 310 is used to connect to the vehicle chassis 810; the magnetic plate 320 is connected to the end of the retractable member 310 away from the vehicle chassis 810; the retractable member 310 is used to drive the magnetic plate 320 to move closer to or further away from the first magnetic traction assembly 200. The telescopic characteristics of the telescopic component 310 cause the magnetic plate 320 to move closer to or further away from the first magnetic component 200. This allows the magnetic plate 320 to move closer to the first magnetic component 200 when the first magnetic component 200 is energized, thus reducing the distance between them and increasing the magnetic attraction. When the first magnetic component 200 is de-energized, the telescopic component 310 controls the magnetic plate 320 to move further away from the first magnetic component 200, thus reducing the distance between the magnetic plate 320 and the car chassis 810. This reduces the restriction or obstruction of the movement of the car 800 during normal operation, especially when the car 800 travels over uneven terrain, reducing the possibility of the magnetic plate 320 colliding with the ground.

[0053] In one specific embodiment, the magnetic plate 320 is an armature plate. The retractable member 310 is a spring. Of course, in other embodiments, the magnetic plate 320 can also be made of other metal materials that can conduct magnetism and accept magnetic attraction. The retractable member 310 can also be a retractable cylinder or other structures.

[0054] Please see Figure 4 In some embodiments, the second magnetic traction assembly 300 further includes a fixing plate 330 connected to the side of the retractable member 310 away from the magnetic traction plate 320, and the fixing plate 330 is used to connect the retractable member 310 to the vehicle chassis 810.

[0055] Please see Figure 1 In some embodiments, when the first magnetic traction assembly 200 is energized, the magnetic traction plate 320 can abut against the support platform 100. By enabling the magnetic traction plate 320 to abut against the support platform 100 when the first magnetic traction assembly 200 is energized, the connection stability between the magnetic traction plate 320 and the support component is improved, thereby making the rear-loading truck 800 safer during unloading and reducing the risk of rear-end rollover.

[0056] In some embodiments, the second magnetic chuck assembly 300 further includes a second battery cell and a second coil. The second battery cell is connected to the magnetic chuck plate 320; the second coil is wound around the outer periphery of the second battery cell, and its two ends are used for electrical connection; the telescopic member 310 is sleeved on the outer periphery of the second coil; wherein, when the second coil is energized, the magnetic chuck plate 320 can generate a magnetic attraction force that attracts the magnetic chuck top plate 230. With this arrangement, the magnetic attraction force generated between the magnetic chuck plate 320 and the magnetic chuck top plate 230 can be made greater, thereby making the rear-loading truck 800 less prone to rear-end rollover during unloading, and making the unloading operation safer.

[0057] Please see Figure 1 and Figure 2 In some embodiments, the anti-tipping device further includes a limiting member 700; the limiting member 700 is installed on the side of the support platform 100 near the second magnetic suction assembly 300. By providing the limiting member 700, the limiting member 700 can limit the unloading position of the vehicle 800 during rear-discharge operations, thereby making the relative positions of the first magnetic suction assembly 200 and the second magnetic suction assembly 300 along the thickness direction of the support platform 100 more accurate during the unloading process. In some embodiments, the limiting member 700 can be a concrete retaining wall.

[0058] In some embodiments, the anti-tipping device further includes a controller; the controller is mounted on the vehicle 800; and the controller is electrically connected to the first magnetic chuck assembly 200 and the second magnetic chuck assembly 300; when the vehicle 800 moves to a preset position relative to the limiting member 700, the controller energizes the first magnetic chuck assembly 200 and the second magnetic chuck assembly 300. By controlling the electrical connection of the first magnetic chuck assembly 200 and the second magnetic chuck assembly 300, the operation of the entire anti-tipping device becomes simpler and more convenient. Simultaneously, when the vehicle 800 moves to the preset position relative to the limiting member 700, the controller energizes the first magnetic chuck assembly 200 and the second magnetic chuck assembly 300, thereby achieving higher positioning accuracy when the first magnetic chuck assembly 200 and the second magnetic chuck assembly 300 are energized.

[0059] Please see Figure 1 In some embodiments, when the distance d between the rear wheels of the vehicle 800 and the limiting member 700 is less than or equal to a preset value, the controller energizes the first magnetic attraction component 200 and the second magnetic attraction component 300. In one specific embodiment, d can be 0. That is, when the rear wheels of the vehicle 800 abut against the limiting member 700, the first magnetic attraction component 200 and the second magnetic attraction component 300 are energized.

[0060] In some embodiments, the controller is connected to an intelligent control system. By controlling the intelligent control system, the retractable member 310 can be changed from a retracted state to an extended state. The magnetic suction plate 320 connected to the retractable member 310 abuts against the magnetic suction top plate 230 and forms a whole, thereby ensuring the unloading safety of the rear unloading truck 800.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
