Hydraulic-drive movable bridge

Abstract

The invention discloses a hydraulic-drive movable bridge. The hydraulic-drive movable bridge comprises a bridge steel body, a riverway, mounting bases, supports, oil cylinders, support columns, buzzermounting racks, mounting grooves, travel switches, hydraulic transmission systems and well slots and is characterized in that the mounting grooves are symmetrically formed in two sides of the riverway, one mounting base is mounted on one side, away from the riverway of each mounting groove, one support is mounted on the upper surface of each mounting base through bolts, each support is rotatablyconnected with the corresponding end of the bridge steel body, one oil cylinder is rotatably mounted at the bottom of each mounting groove, and the top end of each oil cylinder is rotatably connectedwith the bridge steel body. The hydraulic-drive movable bridge has the advantages that the opening and closing the movable bridge are controlled through the hydraulic ejector pins of the hydraulic transmission systems, the opening and closing can be completed stably, and vibration and noise are reduced to improve the environment of a park; the hydraulic transmission control adopts oil return oil filters and high-pressure filters, hydraulic oil returning oil tanks can be kept clean, hydraulic component abrasion is reduced, and hydraulic system faults are prevented.

Description

technical field [0001] The invention relates to the technical field of opening and closing bridges, in particular to a hydraulically driven opening and closing bridge. Background technique [0002] The use and existence of Kaihe Bridge in large-scale tourism and entertainment venues is of great significance. In large-scale tourism and entertainment venues and some theme parks, some lake water systems are often built for tourists to enjoy. There are artificial canals between the lakes. In order to facilitate the passage of tourists and pedestrians or the quick and rapid operation of fire trucks in public facilities, some important positions in the canal are equipped with special equipment such as opening and closing bridges. The closing bridge can be opened quickly and stably, and the opening and closing bridge will be closed immediately after the ship passes through. It is convenient and flexible to use, simple to operate, safe and reliable. With the increasing development ...

AI Technical Summary

Problems solved by technology

[0003] In the application of the stage, the opening and closing bridge is also widely used as a unique form of stage performance, and the hydraulically driven opening and closing bridge is designed as an opening and closing bridge combined with the real mountain in the park. The operation is relatively stable, the opening and closing speed is fast, and the opening and closing process is relatively smooth. However, most opening and closing bridges use gear transmission, wire rope traction, or chain transmission to control the opening and closing process of the opening and closing bridge. The process of mechanical transmission is inevitable. It will produce some vibration and noise, which will affect the environment of the park and hinder the normal work of the staff. For this reason, we propose a hydraulically driven opening and closing bridge
