Adjustable height limiting frame for road construction

Abstract

The invention belongs to the field of height limiting frames, and particularly relates to an adjustable height limiting frame for road construction. A first cross beam and a second cross beam which are in threaded connection are fixedly mounted at the tops of two top vertical plates of a mounting seat respectively, and adjusting blocks are fixedly mounted at the sides, away from each other, of thetwo vertical plates; lead screws in threaded connection with driving blocks are rotationally installed on the inner walls of the bottoms of the adjusting blocks, rotating pieces are fixedly installedon the sides, close to each other, of the two driving blocks, and the two rotating pieces penetrate through the inner walls of the sides, close to each other, of the two adjusting blocks and the sides, away from each other, of the two vertical plates correspondingly and extend to the sides, close to each other, of the two vertical plates correspondingly. The two lead screws are both in transmission connection with an adjusting assembly, and the sides, close to each other, of the two rotating pieces are rotationally provided with a first height limiting pipe and a second height limiting pipe which are provided with anti-collision assemblies correspondingly. The problems that an adjustable height limiting frame is not reasonable enough in design, cannot be suitable for roads of different sizes, and is damaged when the vehicle reaches the frame for mistake due to lack of a buffering device are solved.

Description

technical field [0001] The invention belongs to the field of height-limiting bridges, and relates to an adjustable height-limiting bridge for road construction. Background technique [0002] The height-limiting overpass is an important traffic restriction tool on the road. The setting of the height-limiting overpass can effectively limit the height of vehicles on the road, thereby effectively preventing vehicles from damaging bridges, tunnels, cables and other facilities above the road, or by limiting the height of vehicles. To limit the load capacity of vehicles, so as to achieve the effect of protecting the road, and the height limit frame is generally divided into two types, fixed and adjustable, so that the use of the height limit frame is more suitable for the actual situation. Therefore, for a road construction The demand for adjustable road height limiters is increasing day by day. [0003] The design of most of the adjustable height limiters currently on the market ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, in order to solve the problem that the design of the adjustable height-limiting frame is not reasonable enough and cannot be applied to roads of different sizes, it is necessary to repeatedly transport and adjust the position of the height-limiting frame, and the labor intensity is high. There is no buffer device for the height limit frame. When the vehicle touches the height limit frame by mistake, it will cause damage to the height limit frame. An adjustable height limit frame for road construction is provided.
