Abstract

The invention belongs to the technical field of special equipment construction, and particularly relates to an auxiliary ascending device. The auxiliary ascending device is arranged in a cylindrical container and comprises a vertical column vertically arranged in the container and a plurality of support assemblies horizontally arranged on the vertical column, wherein the support assemblies are abutted against the inner wall of the container in a telescopic manner. According to the internal structural characteristics of the vertical cylindrical pressure container, the plurality of cross bars are uniformly distributed on the same layer, so that the torsion of the internal construction device of the scaffold of the vertical cylindrical pressure container is prevented. The telescopic piece skillfully utilizes the threads to carry out screw adding and screw subtracting, so that the whole supporting component can be firmly fixed between the upright post and the inner wall of the container, and the safety performance of the tool is met.

Description

Auxiliary ascending device Technical Field The invention belongs to the technical field of special equipment construction, and particularly relates to an auxiliary ascending device. Background The special equipment is inspected at regular intervals by a special equipment using unit, and preparation work including raffinate treatment, steam blowing, ventilation replacement, cleaning, weld polishing and the like is needed before inspection for a movable container for containing inflammable, explosive, combustion-supporting, toxic or suffocating mediums. In order to finish the operations of grinding the welding lines in the container and detecting the same height in the later period, the common practice is to build a full-hall fastener type scaffold in the container, and the scaffold built in the closed space is a work with extremely high risk, and has the advantages of long time consumption, large workload and extremely high requirements on safety and structural stability. The vertical cylindrical pressure vessel has narrow space and larger ratio of height to diameter, and the construction of the full-hall fastener scaffold is not applicable due to the special structural characteristics of the vertical cylindrical pressure vessel. In order to solve the problems, the invention provides an auxiliary ascending device capable of performing construction operation in a vertical cylindrical pressure vessel. Disclosure of Invention The invention aims to solve the technical problems, and aims to provide an auxiliary ascending device which can be built in a vertical cylindrical pressure container, so that workers can construct the inner wall of the vertical cylindrical pressure container. According to the present invention, there is provided an auxiliary ascending device provided in a cylindrical container, comprising: The upright post is vertically arranged in the container; the horizontal setting is in a plurality of supporting components on the stand, supporting component passes through telescopic mode butt the inner wall of container. In a specific embodiment, a plurality of the support assemblies are uniformly disposed on the upright at axially spaced intervals. In a specific embodiment, the support assembly comprises: A plurality of cross bars uniformly arranged on the upright column along the circumferential direction, and The telescopic piece is coaxially arranged on the cross rod and is abutted with the inner wall of the container in a telescopic mode. In a specific embodiment, an external thread is arranged on the outer side of the telescopic member, an internal thread is arranged in the cross rod, the external thread of the telescopic member is connected with the internal thread of the cross rod in an adaptive manner, and the telescopic member stretches and contracts relative to the cross rod through threads. In a specific embodiment, the support assembly further comprises a sleeve fixedly disposed on the upright, and the cross bar is coaxially disposed within the sleeve. In a specific embodiment, a side plate is provided at an end of the telescoping member remote from the cross bar, the side plate being adapted to abut an inner wall of the container.
