Combined ladder for tower reactor

Abstract

The invention relates to the technical field of ladder devices, and provides a combined ladder for a tower reactor, which includes a fixed ladder unit and an auxiliary ladder unit; the fixed main beam of the fixed ladder unit is not provided with a side inlet and outlet near the tower reactor. The fixed step is a vacant place; the lower end of the auxiliary ladder unit is hinged at the bottom of the vacant part of the fixed ladder unit, and the two auxiliary main beams are located on the inner side of the auxiliary guardrail and are respectively hinged with movable cover plates; when the auxiliary ladder unit is in a vertical state When the auxiliary elevator unit is in a horizontal state, the movable cladding plate rotates around the hinge to a state parallel to the auxiliary stairs, and the auxiliary ladder unit is used as a passage for up and down passage. The access floor of the ladder unit to the entrance and exit. The provided combined ladder can be used not only as a passage for construction personnel to climb the tower reactor, but also as a passage for carrying various tools and materials in and out of the side entrances and exits.

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 side entrance and exit of the tower reactor. Background technique [0002] Tower reactors are widely used in various fields such as chemical industry, thermal power, sewage treatment, etc. During the maintenance of tower reactors, the replacement of internal filter elements and filter materials, the side feeder is usually installed on the outside of the tower reactor. The exit (manhole) is in and out. The current tower reactors mostly use vertical ladders arranged in the vertical direction or spiral ladders spiraling 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 arranged on the lateral outer side of the side i...

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
