Gantry crane integrated dam

Abstract

The present invention discloses a gantry crane integrated dam in the field of hydraulic engineering facilities. The gantry crane integrated dam comprises a door mounted between lock walls. Side rubberwater seals are mounted on both left and right sides of the door to form seal structures with the lock walls, thereby preventing water leakage on both sides. A bottom rubber water seal is mounted between the bottom of the door and a bottom sill to form a seal structure for preventing bottom water leakage. A plurality of supporting hinge bases are fixed to the bottom sill. The bottom of the door is hinged to the front ends of the supporting hinge bases by means of front pin shafts. A hydraulic oil cylinder is arranged on a land side of the door. One end of the hydraulic oil cylinder is hingedto a back surface of the door by means of an upper pin shaft, and the other end of the hydraulic oil cylinder is hinged to rear ends of the supporting hinge bases by means of rear pin shafts. The device is low in cost, simple to control and convenient to manage, can be applied to a variety of river channels, especially to relatively wide river channels, and has extremely high cost performance.

Description

technical field [0001] The invention relates to a hydraulic facility, in particular to a flip gate. Background technique [0002] In recent years, with the development of social economy and the acceleration of urban modernization, new requirements and contents have been put forward for the construction of urban water conservancy projects. In addition to meeting the requirements of flood control safety, they also need to meet the requirements of improving and beautifying the environment, thus requiring water conservancy projects Gradually realize the transformation from traditional engineering water conservancy to resource water conservancy and ecological water conservancy, pay attention to the landscape and aesthetic requirements of water conservancy projects, and seek new ideas for urban landscape water conservancy planning and design. Because the traditional gate layout requires thick gate piers and protruding hoist bents, which affect the flood control capability and land...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. In order to ensure that the hoist can drive the entire door to rotate from both ends, it is necessary to set a relatively strong bottom shaft tube, and the bottom shaft tube must be integrated, especially for wider rivers. The increase in the size of the shaft tube leads to a sharp increase in cost. The bottom shaft tube needs to form a movable couple with the hinge seat, and its anti-corrosion requirements, strength requirements, and coaxiality requirements are relatively high, which is equivalent to large-sized finishing parts. , its cost is about 40% of the overall steel dam gate

2. Since the door body is driven to rotate from both ends or one end, the hoist needs to be set larger, and the crank arm also needs to be set larger. The hoist itself is a kind of oil cylinder, which needs to be set in the hoist room. Therefore, the setting of the hoist room will also cause the cost to rise

3. Since the pressure of the water from the upstream is also very huge, it is often necessary to set up multiple middle piers in the river channel to install the hinge seats supporting the bottom shaft pipe, and the size of the middle piers is correspondingly relatively large, so that Setting can seriously affect flooding

4. Due to the installation of the bottom shaft tube through the wall, it is difficult to seal the bottom shaft tube and the hoist room, and often due to water leakage from the river to the hoist room, the hoist, electric control device is corroded and the insulation fails, etc.
