Embodiment Construction
[0046] Such as Figure 1-4 As shown, a rack-and-pinion ship lift transmission system operating condition simulation test platform includes a simulation experiment platform (the self-weight of the part that needs to be lifted in the simulation experiment platform is equivalent to the self-weight of the box that the ship lift lifts) and a simulation Gravity loading part (equivalent to the weight of the simulated ship and water);
[0047] The simulated experiment platform includes two groups of vertical racks 8 on the base 13 (during the test, concrete columns can be used to vertically fix the vertical racks 8 in order to improve the fixing effect of the racks 8, or steel columns can be used to fix them. , in order to prevent the vertical rack 8 from falling sideways due to loose fixation during the lifting process), the upper end of the vertical rack 8 is connected by the box beam 7 (the upper end of the vertical rack 8 is fixed, in order to ensure the The vertical rack 8 is te...

The invention relates to a rack and pinion type ship lift transmission system operation condition simulation experiment table and a simulation method. The simulation experiment table comprises a simulation experiment platform and a simulation gravity loading part; the simulation experiment platform comprises two groups of vertical racks arranged on a base, the upper ends of the vertical racks areconnected through a box beam, a simulation lifting platform is arranged between the two groups of vertical racks, large-modulus pinions are meshed with the connected vertical racks, the simulation platform is provided with a gear driving part, and the gear driving part drives the two groups of large-modulus pinions to rotate simultaneously; and the simulation gravity loading part comprises a supporting seat connected with the base, a hydraulic oil cylinder is arranged on the supporting seat, and a power output part of the hydraulic oil cylinder is connected with the simulation lifting platformthrough a Z-shaped connecting rod. The simulation method comprises static load pressure lifting detection and dynamic load pressure lifting detection. The rack and pinion type ship lift transmissionsystem operation condition simulation experiment table is ingenious in structural design, high in practicability and wide in application range, can comprehensively realize simulation experiments of the operation conditions of the ship lift transmission system, and can simulate the influence of wind on the ship lift.
Description
technical field [0001] The invention relates to the technical field of a ship lift transmission system, in particular to a rack and pinion type ship lift transmission system. Background technique [0002] The intricate water system and the height difference of the water flow make the upstream waterway transportation very inconvenient. Compared with the traditional two-line five-level ship lock, the ship lift has an incomparable time advantage for small and medium-sized ships to quickly pass the dam, which is convenient for transportation. Fast unblocking and efficient transportation. Among them, the Three Gorges ship lift is currently the ship lift with the largest scale and technical difficulty in the world. It has the characteristics of high lifting height, large volume and mass, etc. that other ship lifts do not have. At present, there is no mature test device at home and abroad that can realize the quality inspection and fatigue test of the large-module gear and rack of...
