Abstract

The utility model relates to a collapsible height-limited door frame, and aims to provide an anti-collision height-limited door frame for bridge, which has the following advantages: easy mounting and maintenance, high anti-collision performance, and no secondary accident after collision damage. The collapsible height-limited door frame comprises columns, crossbeams, turning devices and a collapsible device. Each turning device is composed of the following components: a vertical rotating member, a horizontal shaft and a horizontal rotating member. The collapsible device is composed of base plates and connection bolts. The turning devices are provided at the upper parts of the columns. Furthermore the vertical rotating members of the turning devices are sleeved outside the columns. One end of each crossbeam is connected with the turning device, and the other end is connected with the collapsible device. The collapsible height-limited door frame can be used for various grades of roads and urban roads, and is suitable for being used as an anti-collision height-limited door frame at the front part of the overpass bridge.

Description

Debacle possible type limit for height door frame
Technical field
The utility model relates to the crashproof limit for height facility of cross-line bridge front portion, particularly a kind of Debacle possible type limit for height door frame.
Background technology
The intersection of highway in China and urban road, having many is to adopt clover leaf form, cross over the upper strata bridge of underpass highway, often be subjected to the collision of indivedual superelevation haulage vehicles, not only make haulage vehicle and institute's cargo impaired, and the safety that may jeopardize bridge, cause bigger traffic accident.In order to prevent that vehicle from hitting bridge, the limit for height alarm set that adopts mainly contains two kinds at present.First kind is common portal-framed structure; Second kind is to be the infrared of representative or laser limit for height alarm set with Chinese utility model patent 01258840.7.When Overheight Vehicles by these limit for height alarm sets are, these two kinds of structures all can realize certain limit for height effect.But all there is obvious deficiency in this dual mode: the limit for height door frame crossbeam of first kind of mode is easy to be knocked by vehicle, causes second accident after falling easily, and the casualty accident that crossbeam falls and causes had taken place repeatedly in the practical application; The deficiency of the second way is that vehicle in case surrounding environment is noisy, does not then have the effect of prompting by being only to provide sound, light to remind, and Overheight Vehicles still can clash into bridge.
The utility model content
The purpose of this utility model provide a kind of crashworthiness good, install and maintenance is quick, can not cause the Debacle possible type limit for height door frame of second accident after breaking, it can overcome the defective of existing height limiter, have simple in structure, easy for installation, characteristics such as reliability is high, easy maintenance, can be applied to construction fields such as highway, urban road.
Debacle possible type limit for height door frame of the present utility model comprises column, crossbeam, transfer and the device of can bursting.Column is divided into the both sides in track, and transfer is positioned at column top, can burst device between two crossbeams.One end of crossbeam is connected with transfer, and the other end is connected with the device of can bursting.
Described this transfer is made of vertical revolving meber, horizontal axis, horizontal rotation spare, and vertical revolving meber is enclosed within the column outside, and horizontal axis vertically is connected with vertical revolving meber, and horizontal rotation spare is enclosed within the outside of horizontal axis.
Described this device of can bursting is made of base plate and connecting bolt.
One end of described crossbeam and the horizontal rotation spare of transfer are connected firmly, and the base plate of the other end and the device of can bursting is connected firmly.
Description of drawings
Fig. 1 is an elevational schematic view of the present utility model;
Fig. 2 is the generalized section of transfer of the present utility model;
Fig. 3 is the generalized section from the device of bursting of the present utility model.
The specific embodiment
As shown in Figure 1, this Debacle possible type limit for height door frame of present embodiment comprises column 1, crossbeam 2, transfer 3 and the device 4 of can bursting.Transfer 3 is positioned at column 1 top, can burst device 4 between two crossbeams 2.One end of crossbeam 2 is connected with transfer 3, and the other end is connected with the device 4 of can bursting.
As shown in Figure 2, transfer 3 is made of vertical revolving meber 5, horizontal axis 6, horizontal rotation spare 7, and horizontal axis 6 vertically is connected with vertical revolving meber 5.Horizontal rotation spare 7 is enclosed within the outside of horizontal axis 6.
As shown in Figure 3, the device 4 of can bursting is made of base plate 9 and connecting bolt 8.Two base plates 9 are connected as a single entity by connecting bolt 8.
Above-mentioned described Debacle possible type limit for height door frame, column is divided into the both sides in track, and transfer is positioned at the top of column, and the vertical revolving meber of transfer is enclosed within the outside of column, one end of crossbeam and the horizontal rotation spare of transfer are connected firmly, and the base plate of the other end and the device of can bursting is connected firmly.
When Overheight Vehicles process limit for height door frame, vehicle roof bump door frame crossbeam, if vehicle mass is lower, the speed of a motor vehicle is lower, and impact force is below design load, and then this Debacle possible type limit for height door frame directly blocks vehicle, stops until vehicle.If vehicle mass is big, speed is higher, impact force has surpassed design load, then this Debacle possible type limit for height door frame disconnects from the device of can bursting, two sections crossbeams rotate around column respectively, thereby impact force is removed, other structures of limit for height door frame are preserved, and the second accident of other vehicle is caused on the crossbeam road surface of can not falling simultaneously; Overheight Vehicles are owing to be subjected to the reaction force of limit for height door frame, and speed reduces, and the driver is subjected to the prompting of Vehicular impact vibrations simultaneously, can initiatively brake if having time, and then protect bridge construction to preserve from.

Claims (4)

1. a Debacle possible type limit for height door frame is characterized in that: comprise column, crossbeam, transfer, the device of can bursting; Column is divided into the both sides in track, and transfer is positioned at column top, can burst device between two crossbeams.
2. Debacle possible type limit for height door frame according to claim 1, it is characterized in that: this transfer is made of vertical revolving meber, horizontal axis, horizontal rotation spare, vertical revolving meber is enclosed within the outside of column, and horizontal axis vertically is connected with vertical revolving meber, and horizontal rotation spare is enclosed within the outside of horizontal axis.
3. Debacle possible type limit for height door frame according to claim 1 is characterized in that: an end of this crossbeam and the horizontal rotation spare of transfer are connected firmly, and the base plate of the other end and the device of can bursting is connected firmly.
