Abstract

A coil hanging device of a boiler superheater relates to a hanging device of the boiler overheater to resolve problems of great machining workload, low efficiency, high fees and easy deformation of hanging tubes of the coil assembly hanging device of the existing boiler superheater. Two ends of a M-shaped bent plate are provided with one semicircle hatch respectively on central position of its width, two top ends of the M-shaped bent plate are all in circular arc shape, center distance between the two circular arc shape top ends of the M-shaped bent plate is equal to that of two neighboring horizontal tubes of the coil tubes, the hanging tube is arranged on the middle of two neighboring coil tubes along the vertical direction, per two M-shaped bent plates are opposite each other, two circular arc shape top ends of the M-shaped bent plate are fastened on the horizontal tube of corresponding coil tube, the hanging tube is located in a semicircle hatch of two corresponding M-shaped bent plates, and the hanging tube is fixedly connected with the M-shaped bent plate. The utility model has advantages of simple production, convenient fixation, little machining workload, high efficiency, non-deformable hanging tubes, and easy satisfaction of design accuracy requirement.

Description

Boiler superheater coiled pipe erecting by overhang

Technical field

The utility model relates to a kind of boiler superheater erecting by overhang.

Background technology

The form of hanging of existing boiler superheater coiled pipe is seen Fig. 5 and Fig. 6, hangs the structure of pipe 1 and sees Fig. 7, and the structure of bent plate 8 is seen Fig. 8.In order to realize hanging, need on the upper and lower end face of bent plate 8, process the gap 81 of wide 7mm, long 70mm, because bent plate 8 adopts stainless steel material (material 1Cr20Ni14Si2), gap 81 is difficult for processing; If adopt the plasma cutting, need after cutting to use the electric angle grinder reconditioning, workload is big, efficient is low, and is difficult to satisfy the design accuracy requirement; If adopt machining, expense is higher, and needs four parts carry out assembly welding when connecting, and welding capacity is big, the welding rod consumption is big.In addition, the single pipe 1 of hanging needs many steel plates 9 of welding and round steel 10, and the welding job amount is big, and hangs pipe 1 easy deformation, needs to proofread and correct.

The utility model content

The purpose of this utility model provides a kind of boiler superheater coiled pipe erecting by overhang, with solve existing boiler superheater coiled pipe erecting by overhang have that labor content is big, efficient is low, expense is high and hang pipe yielding, need calibration problem.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: erecting by overhang of the present utility model comprises hangs pipe, and the described pipe of hanging is straight tube; Described erecting by overhang also comprises a plurality of M type bent plates; The center that the two ends of M type bent plate are positioned at its width respectively is processed with a semicircle opening, two tops of M type bent plate are circular shape, the centre-to-centre spacing on two circular shape tops of M type bent plate equates with the centre-to-centre spacing of adjacent two horizontal tubes of coiled pipe, hang pipe and vertically be arranged on the centre of adjacent two coiled pipes, per two M type bent plates are oppositely arranged, and two circular shape tops of M type bent plate are installed on the horizontal tube of corresponding coiled pipe, hang the semicircle opening that pipe is positioned at two M type bent plates of symmetrical setting, it is affixed with M type bent plate to hang pipe.

The beneficial effects of the utility model are: one, corrosion resistant plate of the present utility model adopts punching technology to process semicircle opening, erecting by overhang only need M type bent plate to be installed on the coiled pipe and with hang that pipe is affixed promptly realizes hanging of coiled pipe, it is made, and simple, convenient fixing, labor content are little, to hang pipe not yielding, need not to proofread and correct to hanging pipe, satisfy the design accuracy requirement easily, improved production efficiency and installation effectiveness.
