Round steel surface derusting mechanism

Abstract

The invention discloses a round steel surface derusting mechanism and belongs to the technical field of derusting equipment. By arranging two supporting sets and controlling short air cylinders in the four telescopic mechanisms to stretch out or draw back, corresponding Z-shaped supporting plates can stretch out and draw back inwards and outwards, clamping of a circular steel pipe or a rectangular steel pipe is achieved, and the effect of supporting steel to be painted is achieved; by arranging an abrasive belt, the abrasive belt is used for derusting the round steel, the abrasive belt is convenient to replace after being abraded, and the use cost of the abrasive belt is low; a abrasive belt mechanism is arranged, a driving belt wheel is driven by a third driving motor to rotate so as to drive the abrasive belt to rotate, and derusting of the outer ring face of the round steel is achieved through rotation of the abrasive belt;by arranging pressing wheel sets, when telescopic electric cylinders stretch out to drive the abrasive belt mechanism to get close to the round steel, the abrasive belt between two large driven belt wheels can be stretched after being attached to the round steel, and the abrasive belt is in a tight state all the time through the elastic force of compression springs in the pressing wheel sets, so that the derusting quality is not reduced.

Description

technical field [0001] The invention belongs to the technical field of derusting equipment, and in particular relates to a round steel surface derusting mechanism. Background technique [0002] One of the main building structure types of steel engineering is one of the more common structural forms in modern construction engineering; steel on the market is often placed in the open air, so the outer surface is easily rusted; for example, the water vapor mixture used in super large power plant boilers The transmission pipelines need to be derusted during welding; however, the existing derusting methods in some small factories are often eliminated by workers rubbing with sandpaper, which is too inefficient; so in order to improve efficiency and derusting quality The rust removal devices for steel on the market are often processed by shot blasting machines, but the following problems will be encountered in the process of use; The cost of regular replacement is high; 2.
