DETAILED DESCRIPTION
[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2 As shown, the new vehicle limiting device for bridge engineering comprises a gantry 1, which is composed of a left support column 2, a right support column 3 and a cross bar 4. A height limiting cross bar 5 for limiting the height of the vehicle is arranged on the gantry 1, and a driving motor 6 is arranged on the left support column 2 and the right support column 3. A screw rod 7 is connected to the motor shaft of the driving motor 6, and a lifting device 8 is arranged on the screw rod 7. The lifting device 8 is connected to the height limiting cross bar 5, and the motor shaft of the driving motor 6 controls the lifting device 8 to move up and down through the screw rod 7. Since the height limiting cross bar 5 is installed on the lifting device 8, the height limiting cross bar 5 and the lifting device 8 move up and down at the same time, and a width limiting device 9 for controlling the width of the vehicle is arranged on the inner side of the left support column 2 and the right support column 3. The width limiting device 9 is composed of a driving trolley 10 and a telescopic fence 11.
[0015] To be more specific, a movable space 12 for the movement of the lifting device 8 and the height-limiting horizontal bar 5 is provided inside the left support column 2 and the right support column 3 .
[0016] To be more specific, a support portion 13 is disposed at the lower end of the left support column 2 and the right support column 3 .
[0017] To further elaborate, the height-limiting horizontal railing 5 is provided with a plurality of warning portions 14 for warning.
[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0019] Although this article uses more terms such as gantry 1, left support column 2, right support column 3, cross bar 4, height limit cross bar 5, drive motor 6, screw 7, lifting device 8, width limit device 9, drive trolley 10, telescopic fence 11, activity space 12, support part 13, warning part 14, etc., it does not exclude the possibility of using other terms. The use of these terms is only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
