Abstract

The invention discloses a structure for dredging concrete mortar in construction steel pipes. The structure comprises a mounting plate which is arranged on the upper side of a steel pipe; a fixing structure which is connected with the steel pipe is arranged on the lower side of the mounting plate; the fixing structure comprises two arc-shaped plates which are rotatably connected with the lower side wall of the mounting plate; an expansion link is fixed on the upper side wall of the mounting plate; the driving end of the expansion link is vertically and upwardly fixed with a U-shaped plate; twoends of the U-shaped plate penetrate through the mounting plate so as to extend to the lower side of the mounting plate and make contact with the outer walls of the arc-shaped plates; a motor I is fixed on the upper side wall of the mounting plate; a soft shaft is fixed at the driving end of the motor I; and the lower end of the soft shaft extends into the steel pipe and is fixed with a drill bit. Through pumping hydraulic oil into an L-shaped pipe or a hose to harden the hose, or electrifying to generate magnetic fields to convert magnetorheological fluids to solid state, the support for thesoft shaft is realized, the soft shaft is ensured to rotate stably, and the drill bit is prevented from deviating from the practical position as the amplitude of swing is too large.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a concrete mortar dredging structure inside a construction steel pipe. Background technique [0002] Steel pipes for construction can be divided into seamless steel pipes and seamed steel pipes according to the seamlessness of seams. Seamed steel pipes are divided into spiral steel pipes and straight seam steel pipes according to the different welds. The two are widely used in construction piling, structure, steel structure, load-bearing, drainage and other aspects. The main materials are carbon steel, stainless steel, alloy steel. Among them, carbon steel is the most commonly used material, and the main production base is Cangzhou, Hebei. According to the customer's requirements, the length of the steel pipe can be fixed or loose. The price of the fixed length is 500-600 yuan more expensive per ton than the loose length. According to the production method, construction s...
