CN201293153Y - Ascending pipe support connector for blast furnace crude gas system - Google Patents

Abstract

The utility model provides an ascending tube supporting block joint of a blast furnace raw gas system, aiming at the problem that the prior supporting block has large welding difficulty and deformation, difficult construction and low efficiency. The ascending tube supporting block joint of a blast furnace raw gas system comprises an upper supporting block and a lower supporting block, wherein the upper supporting block is fixedly connected with the ascending tube; the lower supporting block is fixedly connected with a bottom platform; a ball body is arranged between the upper supporting block and the lower supporting block; the bottom of the upper supporting block is matched with the upper half part of the ball body, and the top of the lower supporting block is matched with the lower half part of the ball body. The technical scheme is as follows: a ball node is adopted for controlling two pipes, the assumed hinge coincidence degree is increased, and the stress is reasonable; meanwhile, the structure lowers the difficulty for manufacturing and welding joints, is easy to construct, greatly improves the construction efficiency and is beneficial to popularization and application.

Description

Blast furnace crude-gas system asending pipe bearing joint

Technical field

The utility model relates to a kind of bearing joint.

Background technique

Blast furnace crude-gas system asending pipe load is heavy, and complex structure is spatial structure, is provided with bearing between its bottom platform and the blast furnace asending pipe, with reference to Fig. 1.

Present seat structure is with reference to the K part among Fig. 2, and this structure exists making and the welding difficulty is big, welding deformation is big, construction and installation are difficult, the drawback of inefficiency.Owing to not exclusively coincide, be unfavorable for actual use simultaneously with reality is hinged.

The model utility content

At present bearing have that the welding difficulty is big, distortion is big, the problem of constructional difficulties, inefficiency, the utility model provides a kind of joint, and it is not only stressed clear and definite, also has welding simultaneously easily, be out of shape the advantage of little and convenient construction, and increase with the pin rocker bearing Percent of contact area of supposing.

A kind of blast furnace crude-gas system asending pipe bearing joint, it comprises upper seat and lower seat, upper seat is fixedlyed connected with asending pipe, lower seat is fixedlyed connected with bottom platform, be provided with spheroid between two bearings, and the bottom of upper seat and spheroid upper half part are suitable, and the top of lower seat and lower half portion of spheroid are suitable.

Described upper seat and lower seat all be cylindrical body and end face diameter all greater than sphere diameter, the position of upper seat and lower seat surface of contact is connected with bolt, realizes the small angle rotation between two bearings of bolt may command.

The advantage that this patent had is as follows:

The technological scheme that this patent is taked is to adopt ball node to constitute between two pipes of control, increases with hinged supposition Percent of contact area, and is stressed reasonable, this structure has reduced the difficulty that joint is made and welded simultaneously, construction has increased substantially efficiency of construction easily, is beneficial to and applies.

Embodiment

Elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.

Blast furnace crude-gas system asending pipe bearing joint (the K part among Fig. 1), described joint is connected to form with spheroid 3 by upper seat 1, the lower seat 2 of charging of blast furnace system.The innovative point of this patent is, with reference to Fig. 3-Fig. 6, upper seat 1 is fixedlyed connected with asending pipe 4, lower seat 2 is fixedlyed connected with bottom platform 5, fix by spheroid 3 between upper seat 1 and the lower seat 2, reduced the making and the welding difficulty of joint, construction has increased substantially efficiency of construction easily.Described upper seat 1 and lower seat 2 all be cylindrical body and end face diameter all greater than the diameter of spheroid 3, the position of upper seat and lower seat surface of contact is connected with bolt 6, the realization small angle rotates between two bearings of bolt 6 may command.The utility model node place adopts ball to connect, and increases with hinged supposition Percent of contact area, and is stressed reasonable, therefore is beneficial to and applies.
