Automatic underwater platform elevator with stable structure

Abstract

The invention discloses an automatic underwater platform elevator with a stable structure. The automatic underwater platform elevator comprises an upper streamline body, a worktable and a lower streamline body; outer water passing pipes are fixedly connected to the left and right ends; inner water passing pipes are clamped at the upper ends in the outer water passing pipes; an extrusion piece is clamped in a first clamping groove; the outer end of the extrusion piece is fixedly connected with a twisting ring; two sets of elastic pieces, symmetrical about an extrusion rod left and right, are fixedly connected to the upper inner wall of the lower streamline body; water passing ports are formed in the inner water passing pipes and the outer water passing pipes; after water enters the water passing ports, a flowing field generated by a flowing direction is destructed, the vortex-induced vibration perpendicular to the water flowing direction is reduced, the structure stability is improved,and the working efficiency is improved; a first clamping piece and an elastic piece are arranged in the lower streamline body; and reactive force is formed when reaching the bottom surface, so that the contact pressure with the bottom surface is increased, the structure stability is further improved, and the automatic underwater platform elevator is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to an automatic underwater platform type lift with a stable structure. Background technique [0002] Elevators, also known as elevators, vertical elevators, elevators carry people or cargo up and down the platform or semi-enclosed platform lifting machinery or devices, which are composed of platforms and equipment for manipulating them, motors, cables and other auxiliary equipment of a whole. [0003] In the prior art, the bottom surface of the workbench of the automatic elevator is generally in a rectangular structure. When it enters the water, it bears the huge resistance from the water flow, and needs to use more mechanical energy to provide kinetic energy, which consumes a lot of energy and slows down. The efficiency is low; and when the worktable enters the water, the water flow is relatively large, and a flow field is generated. The vortex-induced vibration perpendi...

Problems solved by technology

[0003] In the prior art, the bottom surface of the working table of the automatic elevator is generally rectangular in structure. When entering the water, it bears the huge resistance from the water flow, and needs to use more mechanical energy to provide kinetic energy. The efficiency is low; and when the worktable enters the water, the water flow is relatively large, and a flow field is generated. The vortex-induced vibration perpendicular to the direction of the water flow is large, and the downward work cannot be performed smoothly. The structural stability is poor, and it is forced to lower and lower Speed, resulting in low work efficiency, while reaching the bottom, the workbench can not effectively press against the bottom, affecting the quality of work
