Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses an elevation limiting frame for municipal roads, which comprises two vertical frames 1, a support frame 2 is horizontally arranged between the upper ends of the two vertical frames 1, a plurality of vertically arranged rotating sleeves 21 are rotatably connected on the support frame 2, the rotating sleeves 21 can penetrate through the support frame 2, vertically arranged lead screws 22 are uniformly and threadedly connected in the rotating sleeves 21, an elevation limiting plate 3 with the length direction same as that of the support frame 2 is arranged at the lower side of the support frame 2, the elevation limiting plate 3 is vertically arranged, the lower ends of the lead screws 22 are rotatably connected at the upper side of the elevation limiting plate 3, worm rings 23 are fixedly connected at the upper ends of the rotating sleeves 21, the upper side of the vertical frame 1 extends out of the upper side of the support frame 2, a transmission shaft 24 is rotatably connected at the upper side of the support frame 2 along the length direction of the support frame 2, a worm 25 is fixedly connected at the position of the transmission shaft 24 corresponding to each, one end of the support frame 2 corresponding to the transmission shaft 24 is further fixedly connected with a stepping motor 26, and an output shaft of the stepping motor 26 is fixedly connected to the end of the transmission shaft 24. And a graduated scale 11 is vertically and fixedly connected to one side of each vertical frame 1 close to each other. When the height of limit for height board 3 needs to be adjusted, drive transmission shaft 24 through step motor 26 and rotate, can drive each worm 25 and rotate to can drive through each worm wheel ring 23 and rotate cover 21 and rotate, thereby can drive threaded connection and rotate in the lead screw 22 that rotates cover 21, and then can realize the altitude mixture control of limit for height board 3 according to scale 11, thereby be suitable for different operating modes.
Both ends of support frame 2 all rotate to be connected in two grudging posts 1, and all are provided with torsional spring 27 between the both ends of support frame 2 and two grudging posts 1, and under the normality, torsional spring 27 can make the limit for height frame of support frame 2 downside keep vertical state. The upper ends of the two vertical frames 1 are fixedly connected with a monitor mounting seat 12, the monitor mounting seat 12 is fixedly connected with a monitor, the two sides of the height limiting plate 3 are provided with a reflecting plate 31, and the middle of the limiting plate is fixedly connected with a height warning board 32. Support frame 2 through adopting rotates to be connected in grudging post 1, can be when the super high vehicle high speed rush through the limit for height frame appearing, make limit for height board 3 can rotate and make the vehicle pass through, avoid the limit for height frame to block super high vehicle, damage vehicle and road facilities, in addition, torsional spring 27 can make limit for height board 3 normality keep vertical state down, and realize limit for height board 3 quick reset, thereby guarantee that support frame 2 can be in vertical state under the non-stress state, thereby avoid support frame 2 to swing along with the wind, convenient to use. Secondly again, the reflector panel 31 of adoption can have fine warning effect night, reminds the driving, and the high warning sign 32 of adoption can be convenient for the driving and observe the height of limit for height board 3 to can the person of facilitating the use make clear of whether self vehicle can pass through, the monitor mount pad 12 of adoption can install the monitor, thereby monitors the video recording to the vehicle of coming and going, thereby the record vehicle of violating the rules and regulations.
The implementation principle of the embodiment is as follows: when the height of limit for height board 3 needs to be adjusted, drive transmission shaft 24 through step motor 26 and rotate, can drive each worm 25 and rotate to can drive through each worm wheel ring 23 and rotate cover 21 and rotate, thereby can drive threaded connection and rotate in the lead screw 22 that rotates cover 21, and then can realize the altitude mixture control of limit for height board 3 according to scale 11, thereby be suitable for different operating modes. Support frame 2 through adopting rotates to be connected in grudging post 1, can be when the super high vehicle high speed rush through the limit for height frame appearing, make limit for height board 3 can rotate and make the vehicle pass through, avoid the limit for height frame to block super high vehicle, damage vehicle and road facilities, in addition, torsional spring 27 can make limit for height board 3 normality keep vertical state down, and realize limit for height board 3 quick reset, thereby guarantee that support frame 2 can be in vertical state under the non-stress state, thereby avoid support frame 2 to swing along with the wind, convenient to use.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
