Detailed Description

Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating a bridge translation device for an underground chamber according to an embodiment of the present application. As can be seen from fig. 1, the bridge girder translation device for an underground chamber provided by the embodiment of the application is formed by sequentially connecting a plurality of detachable translation girders. The translation beam can be detached to move, and is further suitable for translation of bridge girders with different lengths. In this application embodiment, for the connection that realizes a plurality of translation roof beams, can adopt bolted connection, also can adopt to tie up rope connection or buckle connection etc. as long as can realize the connection of a plurality of translation roof beams.

The translation beam provided by the embodiment of the application comprises two support columns 1 arranged in parallel and a rail table top 2 arranged on the tops of the two support columns 1, as shown in fig. 2-4. The support column 1 is a part that supports the rail deck 2, and thus it is required to have high structural strength. In order to improve the stability of the supporting column 1, the supporting column 1 in the embodiment of the present application is a trapezoidal column, so as to increase the contact area between the supporting column 1 and the ground. Further, the support column 1 in the embodiment of the present application is a thick-walled square steel trapezoidal column.

The rail deck 2 is a part that provides a transportation rail for the bridge translation and is welded to the support column 1. From this, support column 1 and track mesa 2 form overall structure, have further strengthened the structural strength of translation roof beam. Preferably, the track table top 2 in the embodiment of the present application is a thick-walled square steel beam. In order to reduce the overall weight of the support column 1 and the track table top 2, the support column 1 and the track table top 2 are both hollow. Thereby, a translation beam of lighter weight can facilitate the movement.

A track 3 is arranged above the track table top 2, and the track 3 can facilitate the movement of the belt wheel bridge girder. In the embodiment of the present application, the surface of the rail table top 2 is welded with the rail clamp plate 6, and the rail 3 is detachably disposed on the rail table top 2 through the rail clamp plate 6, so that the rail 3 is fixedly disposed on the rail table top 2, as shown in fig. 5. Preferably, the rail 3 in the embodiment of the present application is an i-steel.

For realizing the connection of a plurality of translation roof beams, the both sides of support column 1 in this application embodiment are equipped with connecting plate 4 respectively, are equipped with screw hole 5 on this connecting plate 4, consequently, adopt the bolt with screw hole 5 to connect the back just can realize the connection of a plurality of translation roof beams. The number of the translation beams is determined according to the length of the track 3 required by a construction site, and the length of the track 3 is determined according to the length of the bridge girder of the construction site.

The bridge girder translation device for underground chamber that this application embodiment provided comprises a plurality of detachable translation roof beams in the same direction as connecing, because the translation roof beam can insert the detachable connection, therefore bridge girder translation device can be according to the length adjustment translation roof beam's of construction site bridge concatenation length of roof beam, and then promotes through track 3 of laying on track mesa 2 and pulls the belt wheel bridge girder. The translation roof beam that this application embodiment provided simple structure, easily dismouting can effectively adjust the position of belt wheel axle machine roof beam by a wide margin, and then adjusts the position of lifting by crane of belt wheel axle machine roof beam.
