Problems solved by technology

[0002] The main disadvantages of existing bridges of this type are their complex structure, their large size, they have support structures on each side of the channel, which requires a lot of construction work, especially when they are built in water, and they must be equipped with lifting devices , the lifting device should have a power supply and be well coordinated, which leads to an overly complex design

Embodiment Construction

[0026] As shown in the figure, the lifting bridge 1 according to the present invention is used to cross the seaway 2, and it mainly includes a substantially horizontal, movable bridge body 3 part, which can be used in the base position of the crossing waterway 2 and when opening the waterway. Carry out substantially vertical movement between the high position (raised position) of jumper body 3, and two fixed parts 4 and 5 at the two ends of jumper body 3, jumper body is placed on the bridge body by its two ends 9 and 10 in the straddle position 7 and 8 of the fixed part. The bridge also comprises a support structure 12 for the jumper 3 when moving between the position of the jumper spanning the fairway and the position of the open fairway, and means 14 for controlling the movement of the jumper, hereinafter referred to as hoisting means.

[0027] As shown, the lifting bridge 1 according to the invention has only a single supporting structure and a single lifting control device...

Abstract

The invention relates to a bridge, particularly for crossing a passage of a navigation channel. The bridge comprises a section in the form of a single span (3), which may be displaced by vertical translation between a base position spanning the passage (2), in which the span (3) rests on fixed support sections of the bridge and a raised position, for opening the passage and a support structure for the span on displacement thereof and means for lifting the span. The bridge is characterised in having only one support structure (12), provided with lifting means (14), arranged to one side (5) of the passage (2) to be spanned. The invention is of use for bridges spanning a river.

Description

technical field [0001] The present invention relates to a bridge, particularly for use across a fairway, comprising: a spanning body portion passing through a base spanning a fairway at a position where the spanning body abuts against a fixed support portion of the bridge ) and the elevated position of the open channel, as well as the support structure of the span body and the lifting device of the span body when the span body moves. Background technique [0002] The main disadvantages of existing bridges of this type are their complex structure, their large size, they have support structures on each side of the channel, which requires a lot of construction work, especially when they are built in water, and they must be equipped with lifting devices , the lifting device should have a power supply and be well coordinated, which leads to an overly complex design. Contents of the invention [0003] The object of the present invention is to provide a bridge which does not hav...
