Description

Technical Field

[0001] This utility model relates to the field of maintenance and repair technology for arc gates in hydropower stations, and more specifically to the field of a large arc gate hinge loading test platform. Background Technology

[0002] Hydropower stations, reservoirs, and other water conservancy projects are generally equipped with arc-shaped gates to intercept water flow, control water levels, regulate flow, and discharge silt and floating debris. Arc-shaped gates mainly consist of the gate itself, support arms, and hinges. The gate and support arms rotate around the hinges, which act as fulcrums, providing support during the opening and closing of the arc-shaped gate. The hinges of large arc-shaped gates are characterized by their heavy weight, large size, and high load-bearing capacity, making installation difficult. Improper manufacturing and transportation, inappropriate installation methods, and inadequate maintenance can all lead to residual stress, cracks, and damage in the hinges. When such defects occur, repairs such as heat treatment and welding are necessary. During repair, the hinges must be simulated under the loading conditions when connected to the gate. Whether the simulated loading test of the hinges matches their actual working condition is crucial for the smooth progress of the repair work and ensures the normal operation of the arc-shaped gate after repair.

[0003] Currently, there is no good method to simulate the loading state of the gate when the gate is connected by the hinge during repair. Generally, the repair is carried out directly. This method does not take into account the impact of key factors such as the water pressure on the gate, the weight of the gate and its support arm, and the weight of the hinge itself on the repair process, as well as the potential residual problems. Therefore, it will affect the service life of the hinge after repair and the safe operation of the gate.

[0004] Therefore, based on the on-site working conditions, we developed a large-scale arc gate hinge loading test platform. This platform is used to simulate parameters such as the gate water pressure, the gate and support arm self-weight, and the hinge body self-weight during the repair and testing of large arc gate hinges. This ensures that the stress on the hinges during repair is consistent with the working state, improves the quality of repair, and guarantees the safe operation of the hinges and gates.
