Abstract
The utility model relates to a kind of prestressing force limit for height door frame.The limit for height door frame that object is to provide effectively should be able to ensure the safety of Vehicle And Personnel, and has structure feature simply firm and easy to maintenance.Technical scheme is: a kind of prestressing force limit for height door frame, comprises level across the height-limiting bar above road and be vertically fixed on road both sides and two root posts for supporting height-limiting bar two ends respectively; It is characterized in that: the top of described every root post fixes one along the gripper shoe of road direction horizontal-extending; Described height-limiting bar can shelve respectively on the supporting plate horizontally slidingly and the two ends of height-limiting bar are connected by elastic rope with column top.
Description
Technical field
The utility model relates to a kind of height limiting device being arranged on bridge crossing, tunnel, inlet of culvert place, specifically a kind of prestressing force limit for height door frame.
Background technology
Limit for height door frame is arranged on the link entry place of the means of transportation such as bridge crossing, tunnel, culvert usually, can limit the current safety protecting means of transportation and vehicle of Overheight Vehicles.
But height-limiting bar is fixed on above road in existing limit for height door frame; when Overheight Vehicles directly will clash into height-limiting bar by during limit for height door frame; though vehicle and means of transportation can be stoped like this to collide; the safety of protection means of transportation; but vehicle and limit for height door frame can be subject to damage (passengers inside the car also there will be casualty situations) in various degree; and limit for height door frame also will carry out maintain and replace (maintenance cost is also higher), therefore requires further improvement.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, and provide a kind of prestressing force limit for height door frame, this limit for height door frame effectively should be able to ensure the safety of Vehicle And Personnel, and has structure feature simply firm and easy to maintenance.
The technical solution of the utility model is: a kind of prestressing force limit for height door frame, comprises level across the height-limiting bar above road and be vertically fixed on road both sides and two root posts for supporting height-limiting bar two ends respectively; It is characterized in that: the top of described every root post fixes one along the gripper shoe of road direction horizontal-extending; Described height-limiting bar can shelve respectively on the supporting plate horizontally slidingly and the two ends of height-limiting bar are connected by elastic rope with column top.
Described height-limiting bar is hollow stem, and described elastic rope passes through the inner chamber of height-limiting bar and the two ends of elastic rope are fixed on column top by screw rod.
The quantity of described elastic rope is 3-5 bar.
Described elastic rope is wire rope.
The beneficial effects of the utility model are:
The utility model effectively can slow down the collision of Overheight Vehicles, ensures the safety of vehicle and personnel, and structure is very simple simultaneously, and more for convenience, manufacturing cost is also lower in installation and maintenance, very suitable for large-scale promotion.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of prestressing force limit for height door frame, comprises height-limiting bar 1 and two root posts 2; Described height-limiting bar level, across above road, can be used for stopping the current of Overheight Vehicles; Described column is vertically fixed on road both sides and supports the two ends of height-limiting bar.
Improvements of the present utility model are:
Every root post is all fixed with gripper shoe 3, and this gripper shoe is from the top of column toward road direction horizontal-extending (Fig. 2 shown in arrow A); On the supporting plate thus be positioned at above road, and height-limiting bar can horizontal slip on the supporting plate in the two ends erection of height-limiting bar;
The two ends of described height-limiting bar are connected by elastic rope 4 with column top; This elastic rope generally adopts has higher-strength and retractable wire rope; Described height-limiting bar is the through hollow stem of length direction, and wire rope passes through the inner chamber of height-limiting bar and by screw rod, two ends is fixed on column top; The sidewall of height-limiting bar is shaped with the through hole (omitting in figure) that can pass through for wire rope; The quantity of wire rope can be 3-5 bar, to ensure enough impact strengths.
In normal state, height-limiting bar is tightened up by elastic rope thus draws close on column; When Overheight Vehicles impinge upon on height-limiting bar by during limit for height door frame, height-limiting bar issues life in the promotion of vehicle and moves and constantly elongate elastic rope, thus forces vehicle to slow down until stop completely gradually; And height-limiting bar can be retracted original position by elastic rope when vehicle rollback, height-limiting bar continues to play limit for height effect.
