Problems solved by technology

The movable road bridge in the prior art usually uses a motor or a hydraulic system to drive the hoist, pulls the wire rope through the hoist, and relies on the wire rope and the wire rope drum to transmit power to make the movable road bridge rise or fall. This type of movable road bridge is often complex in structure
Moreover, due to the long transmission chain, large transmission ratio and low efficiency, the navigation efficiency is low, and the corresponding equipment is relatively large and expensive

Embodiment Construction

[0026] Such as Figure 1~Figure 4 As shown, a split-type bottom-push movable highway bridge is divided into two unilateral bridge bodies, and the two unilateral bridge bodies are arranged symmetrically. Each unilateral bridge body includes a bridge body structure 1 and an opening and closing oil cylinder 2 . The opening and closing of the unilateral bridge body is all realized by pushing the bridge body structure 1 at the bottom of the double lifting point opening and closing oil cylinder 2 .

[0027] The bottom of the bridge structure 1 is connected to the fixed support 5, the bottom of the tail of the bridge structure 1 is connected to the opening and closing cylinder 2 through the hinge support 4, and the opening and closing cylinder 2 is connected to the equipment embedded part 9;

[0028] In order to reduce the opening and closing force, a balance weight 3 is suspended at the end of the bridge structure 1 to balance the self-weight of the bridge structure.

[0029] The ...

Abstract

The invention discloses a split type bottom pushing movable road bridge. The movable road bridge is separated into two single-side bridge bodies which are symmetrically arranged; the single-side bridge bodies comprise bridge body structures and start-stop oil cylinders, fixed bearings are connected to the bottoms of the bridge body structures, the bottoms of the tails of the bridge body structures are connected with the start-stop oil cylinders through hinge bearings, and the start-stop oil cylinders are connected with device embedding parts; and balance weights are hung at the tail parts of the bridge body structures, and locking devices are arranged at the tail parts of the bridge body structures. The split type bottom pushing movable road bridge can avoid the condition that when extending out completely, parts of the start-stop oil cylinders of the movable road bridge easily exceed the building structures so that the influence on ship navigation or collision with a ship body is caused; and simultaneously, the problem that as the rigidity synchronization of the start-stop oil cylinders of the movable road bridge cannot be consistent easily, the interference with related structures can occur easily can be avoided.

Description

technical field [0001] The invention is a split-type bottom push movable road bridge, which is mainly suitable for water conservancy and navigation structures such as ship lifts and ship locks. Background technique [0002] The split-type bottom-push movable road bridge is a facility that sets thrust equipment at the bottom of the bridge to realize the opening and closing of the bridge body, so that ships passing through the ship lift (or ship lock) can pass through smoothly, and it can be used when it is below a certain navigable water level. Open or ensure land passage in the state of not passing the ship. The movable road bridge in the prior art usually uses a motor or a hydraulic system to drive the hoist, pulls the wire rope through the hoist, and relies on the wire rope and the wire rope drum to transmit power to make the movable road bridge rise or fall. This type of movable road bridge is often complex in structure. And because the transmission chain is long, the tr...
