Rotary type steel pipe surface cleaning device

Abstract

The invention relates to a rotary type steel pipe surface cleaning device which is characterized by comprising a rotary brush bracket and a lifting base, wherein the rotary brush bracket is arranged on the lifting base and comprises a fixing seat, bearings, brush heads, a belt pulley and an inner ring; the bearings are arranged between the inner ring and the fixing seat; the brush heads are centripetally and circumferentially distributed on the inner ring; the belt pulley is arranged on one sides of the inner ring; the lifting base comprises an upper platform, lifting guide devices, lifting hinges, a spiral adjusting mechanism and a tail margin bearing plate; the lifting guide devices and the lifting hinges are arranged between the upper platform and the tail margin bearing plate respectively; and the two groups of lifting hinges are connected with each other through the spiral adjusting mechanism. Compared with the prior art, the invention has the benefits as follows: the covering area of steel brushes is large, the dust removing effect is good, and the accuracy of pipe body flaw detection is improved; and 2, the change of steel pipe specification is convenient and only requires corresponding adjustment but large-scale disassembly and dismounting, so as to reduce auxiliary operation time and labor intensity.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a rotary steel pipe surface cleaning device. Background technique [0002] Before the steel pipe is inspected by the pipe body flaw detector, the outer surface of the steel pipe needs to be deashed and iron scale removed, otherwise the flaw detection will have a high misjudgment rate, which will affect the smooth progress of production. At present, the dust removal on the outer surface of the steel pipe is mainly done manually with a steel brush or polished with a small electric tool. The work efficiency is low, and the steel pipe needs to be processed off-line; The principle of the fixed steel pipe outer surface cleaning device is that a ring of steel brushes is set on the brush holder, and the steel pipe passes through the steel brushes. The disadvantages are: [0003] 1) The coverage of the steel brush is small, and the dust removal effect is not ideal. [0004] 2) The ash removal dev...
