H shaped steel is that a kind of area of section distributes the rational more efficient section bar of economic section of optimization, the ratio of strength to weight more, gains the name because of its section is identical with English alphabet H.H shaped steel has that bending resistance is strong, construction is simple, practice thrift advantages such as cost and lightweight construction, has been widely used in using as building materials in the industries such as building, bridge, tower mast and rack, and H shaped steel is as main supporting member in the multi-storied garage industry; Need be at the suspension column place of H shaped steel welded post sole and upper plate; Mainly position during welding, adopt manual work to put that the location is coarse, uniformity is poor, and take more human resources through manual work; Increased production cost; Simultaneously artificial positioning action trouble, holding time is long, and production efficiency is low.In order to guarantee the welding quality of H shaped steel and base plate, when welding, also need H shaped steel be overturn, because H shaped steel volume, weight are all very big; Thereby at when welding upset H shaped steel difficulty especially, at present manual types H shaped steel that overturn that adopt need be operated with crane more; Not only inefficiency, the operation loaded down with trivial details; And the operating personnel that need are many, and poor stability is prone to accidents.To the problems referred to above; Someone has proposed concrete solution; Disclosed by patent of invention He Chunrong, Lin Wei design, that the patent No. is 201010193509.4, name is called a kind of H shaped steel suspension column special welding machine like State Intellectual Property Office on July 25th, 2012; This special welding machine comprises turning rolls, passes platform and template, on one group of turning rolls, be provided with can 360 degree rotate on turning rolls roller, said roller comprises roller cap and roller bodies; Roller cap and roller bodies cooperatively interact and constitute the installation region of H shaped steel jointly, in this installation region, are provided with and the suitable fixed mount of H shaped steel to be welded; Pass the end that platform is arranged on turning rolls, be arranged in the push pedal of passing platform with the suitable template of base plate to be welded; The center of one group of roller and template is arranged on the same straight line.During use, at first winch to base plate to it with crane and pass in the frame push pedal, use bolt, cylinder is released and is put in place.Simultaneously, lift oneself to H shaped steel by crane and open on the roller inner fixed stand of roller cap, and make H shaped steel one end be close to the base plate face, clamping is fastening good then.Manual work is got the location lines of having drawn on the reinforcement aligning base plate to be welded and is carried out the spot welding location, and rotation welds the four sides, unclamps fastening bolt on the base plate, and cylinder is return original position.State Intellectual Property Office is disclosed by patent of invention Lin Wei invention, that the patent No. is 201010193490.3, name is called a kind of H shaped steel column base welding method on July 25th, 2012 for another example, and this welding method adopts special-purpose special welding machine that H shaped steel is hung on the fixed mount in roller; Base plate to be welded is placed in the push pedal of passing platform of special welding machine, in push pedal, is provided with the template suitable with base plate; Base plate and template are fixed together, H shaped steel is passed to passing on the platform and accurate fixing; H shaped steel suspension column is carried out the spot welding gusset, base plate is fixed on the H shaped steel bottom end face; Regain push pedal, H shaped steel and base plate are carried out welding processing; Carry out welding processing through special welding machine rotation H shaped steel and base plate, all accomplish welding processing up to all faces; Base plate separated with template obtain product.In above-mentioned two inventions, first invention is special welding machine, and second invention is the welding method of first invention special welding machine, with first the invention applying date is identical, the patentee is identical, invents one of inventor of artificial first invention.In general; These two inventions only are for the welding quality that guarantees single H shaped steel and base plate H shaped steel to be done flip horizontal along its longitudinal axis; Production efficiency is low; Having satisfied not in the multi-storied garage industry should be in that the welded post sole and needs to keep the requirement of the relative position relation of heel slab and upper plate again at other end welding upper plate at the suspension column place of H shaped steel to H shaped steel in enormous quantities.
