Combined type ladder stand for tower reactor

Abstract

The invention relates to the technical field of ladder stand devices, and provides a combined type ladder stand for a tower reactor. The combined type ladder stand comprises a fixed ladder unit and anauxiliary ladder unit, wherein the side inlet and outlet, close to the tower reactor, of a fixed main beam of the fixed ladder unit is not provided with a fixed ladder step but is a vacancy; the lower end of the auxiliary ladder unit is hinged to the bottom of the vacancy of the fixed ladder unit; two auxiliary main beams are positioned on the inner sides of auxiliary guardrails and are hinged tomovable covering plates through hinges respectively; when the auxiliary ladder unit is in a vertical state, the movable covering plates rotate around the hinges to be parallel to the auxiliary guardrails, and the auxiliary ladder unit serves as a channel for passing up and down; and when the auxiliary ladder unit is in a horizontal state, the movable covering plates rotate around the hinges to beparallel to the auxiliary ladder step, and the auxiliary ladder unit serves as a channel bottom plate of the inlet and outlet. The combined type ladder stand provided by the invention can serve as achannel for a constructor to climb the tower reactor and can also serve as a channel for carrying various tools and materials to enter and exit the side inlet and outlet.

Description

technical field [0001] The invention relates to the technical field of ladder devices, in particular to a ladder arranged outside a tower reactor to provide a passage for climbing up and down and a lateral inlet and outlet into the tower reactor. Background technique [0002] Tower reactors are widely used in various fields such as chemical industry, thermoelectricity, and sewage treatment. During the maintenance of tower reactors, the replacement of internal filter elements and filter materials, the lateral feeder installed outside the tower reactor is usually Exit (manhole) access, the current tower reactor mostly adopts a vertical ladder arranged in the vertical direction or a spiral ladder that spirals upward around the tower reactor. [0003] The vertical ladder is an integral fixed structure with continuous steps. In order to facilitate access to the side inlet and outlet of the tower reactor, the vertical ladder is set on the lateral outside of the side inlet and outl...

AI Technical Summary

Problems solved by technology

Since the ladder deviates from the lateral entrance and exit, it is not convenient to carry various workpieces, filter elements and other raw materials, and it is not conducive to the operation safety of construction personnel

[0004] Due to the spiral structure, the spiral ladder increases the outer diameter of the tower reactor, occupies a large area on site, is not suitable for use in densely arranged tower reactor sites, and is not convenient for the up and down transfer of various workpieces and raw materials
