[0020] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0021] The road height-limiting frame according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] As Figure 1 andFigure 3 As shown in Figure 1 and Figure 3 As shown, the road height limit frame of the embodiment of the present invention may include: a height limit frame main body 1, and the height limit frame main body 1 includes: a mounting frame 11, an adjustable height limiting device 12, and a rotating plate 13. Among them, the mounting frame 11 is arranged on the adjustable height limiting device 12, the rotating plate 13 is rotatably connected to the mounting frame 11, a rolling member 4 is rotatably arranged on the rotating plate 13, a rotation angle sensor 5 is arranged on the mounting frame 11, the rotation angle sensor 5 is connected to the rotating plate 13, and the rotation angle sensor 5 is used to obtain the rotation angle information of the rotating plate 13.

[0023] It should be noted that when the rotating plate 13 is pushed by a vehicle in this embodiment, the rotating plate 13 rotates towards the mounting frame 11, and the rotation angle sensor 5 can obtain the rotation angle information of the rotating plate 13. When the vehicle height is higher, the included angle between the rotating plate 13 and the mounting frame 11 is smaller, and vice versa, the included angle is larger.

[0024] A voice player 6 and a controller 7 are respectively arranged on the adjustable height limiting device 12. The controller 7 is used to be electrically connected to the rotation angle sensor 5 and the voice player 6 respectively. The controller 7 is configured to obtain the vehicle height information through the rotation angle information and play the height information through the voice player 6.

[0025] It should be noted that after the controller 7 in this embodiment obtains the rotation angle information when the vehicle passes through the height limit frame, it judges the vehicle height through the size of the rotation angle. When the vehicle is higher, the rotation angle is larger. It should be noted that the height information corresponding to different angles is preset in the controller 7.

[0026] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as shown in Figure 1 and Figure 6 As shown, the adjustable height limiting device 12 may include: a mounting base 121, a moving column 122, a limiting sliding plate 123, a second motor 124, and a driving screw 125. Among them, the moving column 122 is slidably connected to the mounting base 121, a limiting sliding groove 126 is formed in the inner wall of the mounting base 121, the limiting sliding plate 123 is arranged on the side wall of the moving column 122, the limiting sliding plate 123 is slidably connected to the limiting sliding groove 126, the second motor 124 is arranged on the lower inner wall of the mounting base 121, the driving screw 125 is arranged on the driving end of the second motor 124, and the moving column 122 and the driving screw 125 are in threaded cooperation. A connecting plate 102 is arranged on the mounting frame 11, and the connecting plate 102 is connected to the moving column 122 through a clamp.

[0027] It can be understood that when the second motor 124 described in this embodiment drives the driving screw 125 to rotate, the movable column 122 moves vertically on the mounting base 121 through the threaded structure, and the movable column 122 can drive the mounting frame 11 to move vertically through the connecting plate 102. By adjusting the height of the mounting frame 11, the height limit frame can be suitable for road scenes with different height limit requirements, and has a wide range of applications.

[0028] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a limiting device 8 is provided on the mounting frame 11, and the limiting device 8 includes: a first motor 81 and a stop plate 82, wherein the first motor 81 is provided on the mounting frame 11, and the stop plate 82 is provided on the driving end of the first motor 81, and the stop plate 82 is in contact with the rotating plate 13.

[0029] It can be understood that the first motor 81 described in this embodiment can adjust the position of the abutment plate 82 by rotating the abutment plate 82 to change the rotation range of the rotating plate 13 .

[0030] Furthermore, the abutting plate 82 may be an electromagnet plate, and the abutting plate 82 may be magnetically connected to the rotating plate 13 .

[0031] In order to clearly explain the above embodiment, in one embodiment of the present invention, Figure 1 As shown, two monitoring devices 103 are symmetrically arranged on the moving column 122, and the monitoring device 103 is used to monitor the license plate information and passing information of the vehicle. The controller 7 is electrically connected to the limit device 8 and the monitoring device 103 respectively, and the controller 7 is used to control the limit device 8 and the monitoring device 103 respectively.

[0032] It should be noted that the two monitoring devices 103 cooperate with each other to monitor the passing information of the vehicle when it is moving forward. When one monitoring device 103 detects the vehicle entering and the other monitoring device 103 detects the vehicle reversing and leaving the road, the controller 7 can control the rotation of the support plate 82 through the first motor 81 to facilitate the reversing of the vehicle.

[0033] Specifically, the mounting frame 11 is moved to a suitable height through the adjustable height limit device 12, and the mounting frame 11 drives the rolling element 4 to move to the limited height through the rotating plate 13. When an over-height (exceeding the height limit) vehicle approaches the height limit frame, the monitoring device 103 can obtain the vehicle's license plate information and monitor the movement of the vehicle. The vehicle will push the rotating plate 13 to rotate on the mounting frame 11, and the rotation angle sensor 5 will transmit the obtained rotation angle information to the controller 7. The controller 7 can obtain the height of the vehicle through the rotation angle information, and play a prompt sound of exceeding the height limit through the voice player 6, and indicate the vehicle's license plate number and height exceed the limit, so as to remind the driver that he cannot continue to move forward on the road. At the same time, it also allows the driver to understand the maximum height of his vehicle, so that the driver can make a clear judgment on whether other height limit frames can be passed.

[0034] Many vehicles are not closed trucks, but have open rear compartments. The cargo in such trucks may not be placed flat, and there may be a difference in height. Therefore, many drivers are not very clear about the height of their vehicles. At the same time, when the vehicle pushes the rotating plate 13, the rolling element 4 will rest on the upper surface of the cargo or the compartment. The rolling element 4 can change the sliding friction into rolling friction, which facilitates the movement of the vehicle while protecting the vehicle compartment or cargo.

[0035] In one embodiment of the present invention, Figures 1 - 3 As shown, two height limiting frame bodies 1 are provided, and the two mounting frames 11 are connected by a connecting rod 9 . A sliding hole 101 is provided on the mounting frame 11 , and the sliding hole 101 is slidably connected to the connecting rod 9 .

[0036] The device may further include: a signboard 104 , which is connected to two movable columns 122 through two telescopic fences 105 , and a lighting panel 106 is provided on the signboard 104 .

[0037] It can be understood that the setting of the two height limit frame bodies 1 described in this embodiment can make the height limit frame more stable, increase its service life, and when installing according to the road width, relevant personnel can install the adjustable height limit device 12 more flexibly. The length of the connecting rod 9 is the length of the freely adjustable distance between the two adjustable height limit devices 12.

[0038] In order to clearly explain the above embodiment, in one embodiment of the present invention, as Figures 2 - 4 As shown, the rolling element 4 may include: a first roller 41, two second rollers 42 and two telescopic sleeves 43, the two second rollers 42 and the two telescopic sleeves 43 correspond one to one, wherein the two telescopic sleeves 43 are respectively arranged at both ends of the first roller 41, and the two second rollers 42 are respectively connected to the two telescopic sleeves 43.

[0039] A plurality of first mounting grooves 44 are provided on the first roller 41, and a plurality of threaded connection holes are provided in the first mounting grooves 44. A plurality of second mounting grooves 45 are provided on the second roller 42, and a plurality of threaded connection holes are provided in the second mounting grooves 45. An outer contour plate 46 is connected in the second mounting groove 45 through a threaded connection member, and the outer contour plate 46 can be connected to the first mounting groove 44 through a threaded connection member. It should be noted that rubber soft sheets are respectively provided on the surfaces of the first roller 41, the second roller 42 and the outer contour plate 46 in contact with the target vehicle.

[0040] Specifically, when adjusting the distance between the two adjustable height-limiting devices 12, the second roller 42 can pull or press the corresponding telescopic sleeve 43 to extend or shorten, so as to adjust the length of the rolling member 4. Since the telescopic sleeve 43 is made of a soft material, it may bend during the extension process, affecting the acquisition of height-limiting data. Therefore, the relevant personnel can move the outer contour plate 46 provided in the second mounting groove 45 into the first mounting groove 44, and connect the outer contour plate 46 to the first roller 41 and the second roller 42 respectively through threaded connection members, and support the telescopic sleeve 43 through a plurality of outer contour plates 46.

[0041] Furthermore, a solar charging device and a power storage device are provided on the adjustable height-limiting device 12, which can effectively utilize solar energy and save energy.

[0042] It should be noted that a speed reducer is provided on the driving ends of the motors (the first motor 81 and the second motor 124) mentioned in the above embodiments. The driving end of the motor is connected to the input end of the speed reducer, and the output end of the speed reducer constitutes the driving end of the motor. The speed of the motor output is adjusted through the speed reducer, and the motor is equipped with a brake. The motor can be quickly stopped through the brake.

[0043] The threaded connection members mentioned in the above embodiments can be screws, bolts, etc.

[0044] In summary, the road height-limiting frame of the embodiment of the present invention can prevent the vehicle from having a hard collision with the height-limiting frame, and at the same time detect the vehicle height during the passing of the over-height vehicle, and tell the driver the vehicle over-height and the vehicle height information through voice broadcast.
