Diseño de un sistema de Izaje para accionar la compuerta radial en la laguna de estabilización del canal de riego Cayambe - Pedro Moncayo

Abstract

The Provincial Government of Pichincha is building the irrigation system Cayambe - Pedro Moncayo, which possesses a stabilization lagoon with a capacity of 45000 m3 and by means of a radial gate controls the water level and discharge of flow in the channel, the lagoon is located 1.2 km from the Parish Olmedo, in an area that does not have access to electricity. This type of gate is formed by a curved screen coating type arc with a center of curvature in a pivot shaft and attached by means of radial arms, the current lifting mechanism is a manual hoist located in an uncomfortable area for the operator, rusty mechanical elements and concentration of load lifting in a single point of the gate. In the project rose technical data of in situ radial gate for the elaboration of plans As Built both the gate as the support structure of the lifting system, subsequently the load analysis produced by; friction in the seals, force hydrostatic and own weight, in addition it was determined efforts and factors of safety in the critical elements, obtaining acceptable safety factors. Through an analysis of alternatives were considered to be several systems of manual lifting as: manual hoist, mechanism of gears and gear motor as a future proposal in the case that you install electrical energy in the sector. Using an matrix of competitiveness is selected as the best alternative the manual mechanism of gears planetary type reducers for the lifting of the radial gate, based on the reduction of torque, the main components of such a mechanism are: hoisting drum composed of two sprockets for a better distribution of hoisting load, two reducing stages, formed by straight gear module 8 referred to as planets and satellites, a driving wheel, ratchet wheel and simple roller chains. The mechanism attaches to the dimensions and loads of the gate, improves the location of the operator for lifting, mechanical elements of stainless steel, a plan for proper maintenance, cost analysis and drawings of the proposed mechanism.
