Description

Technical Field

[0001] The utility model relates to the technical field of storage tank manufacturing, in particular to an auxiliary device for installing a storage tank straight ladder. Background Art

[0002] A sealed container for storing liquid or gas is a storage tank. Storage tank engineering is an essential and important infrastructure in industries such as petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy, and national defense. Guardrails, spiral ladders, vertical ladders, pipes and other accessories are installed on the storage tank. When installing and fixing the vertical ladder, a truck crane is needed to lift the prefabricated vertical ladder to the installation location of the storage tank. Then workers use ladders to install and fix the lower part of the vertical ladder. For the upper part of the vertical ladder, workers are sent to a high place by a scissor lift to install and fix the vertical ladder.

[0003] In the prior art, when a vertical ladder is hoisted, the vertical ladder will inevitably shake and deviate. In order to prevent the vertical ladder from colliding with the storage tank, a slip rope is needed to pull the vertical ladder and control the direction of the vertical ladder. However, using the slip rope for pulling still cannot avoid the slight shaking of the vertical ladder, which increases the difficulty of workers in installing the vertical ladder. In response to the above problem, the document with application number: 202321455056.7 discloses an auxiliary device for installing a storage tank vertical ladder, which includes a climbing mechanism and N groups of ladder rod involvement mechanisms. The climbing mechanism includes a ladder and two parallel columns, and a base is fixedly installed at the bottom end of the column. The ladder is arranged obliquely on the front side of the column, and the upper end and the lower end of the ladder are fixedly connected to the column and the base respectively. The utility model connects a plurality of pipe clamp assemblies to the ladder rods on one side of the ladder one by one, and under the counterweight action of the climbing mechanism, the ladder is pulled and positioned to prevent the ladder from shaking or deflecting, so as to facilitate workers to install the ladder. Moreover, by setting the ladder, it is convenient for workers to use the ladder and connect the pipe clamp assembly to the ladder, and it is convenient for workers to use the ladder to climb to a corresponding height and install and fix the ladder, so that the auxiliary device has multiple functions and high practicality.

[0004] However, the following problems are found in the existing patent literature: in the process of fixing the tank ladder, there are disadvantages of cumbersome operation steps, time-consuming and labor-intensive, and because the pipe clamp assembly is fixedly set on its column, it cannot be adjusted according to actual conditions, and there is room for improvement.
