Description

The large span grid dome is installed suspender

Technical field

The utility model relates to a kind of rack suspender is installed, and specifically is that a kind of large span grid dome is installed suspender, is mainly used in the installation of large span storage bin main body rack domes such as colliery, power plant, cement mill.

Background technology

Outdoor heaps such as colliery, power plant, cement mill are got the stock ground and must be adopted totally-enclosed storage according to national requirements for environmental protection at present, mode is economic, practical to be widely adopted owing to large span (diameter is generally at 80-130m, height 40-80m) steel mesh frame housing is gone along with sb. to guard him, this version has two kinds of mounting meanss at present: a kind of is to adopt full hall scaffold high altitude bulk, this installation method does not need large lifting equipment to be adopted by all multiple-projects because technology is simple always.The weak point of this method is to set up a large amount of scaffolds, and labour intensity is big, and is long in time limit.Another kind is to adopt the large lifting equipment installation at high altitude.This installation method labour intensity is little, the duration short, but when setting height(from bottom) surpasses 50m, must could satisfy requirement for height with the large-scale hanging device of 50-200t, average ten thousand yuan of 60-80 of lifting cost.Therefore, big, long in time limit, the high promotion and application that restrict the large span grid dome of expense of labour intensity.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, provide a kind of large span grid dome that suspender is installed, this suspender comprises upper rack posts, lower fulcrum bar, by upper rack posts, lower fulcrum bar configuration node A, Node B, node C, node A place upper rack posts, lower fulcrum bar connects by axis, there is fixed pulley on top at upper rack posts, the upper rack posts of Node B has some adjustment holes, by the fixing upper rack posts jig of tie bolt, on the upper rack posts jig binding bolt is arranged, on the lower fulcrum bar of node C bearing is arranged, lower fulcrum bar is connected with the lower fulcrum bar jig by bolt of rear end plate, on the lower fulcrum bar jig binding bolt is arranged.

The utility model is realized with following technical scheme: a kind of large span grid dome is installed suspender, comprise upper rack posts, lower fulcrum bar, it is characterized in that: by upper rack posts, lower fulcrum bar configuration node A, Node B, node C, node A place upper rack posts, lower fulcrum bar connects by axis, there is fixed pulley on top at upper rack posts, the upper rack posts of Node B has some adjustment holes, by the fixing upper rack posts jig of tie bolt, on the upper rack posts jig binding bolt is arranged, on the lower fulcrum bar of node C bearing is arranged, lower fulcrum bar is connected with the lower fulcrum bar jig by bolt of rear end plate, on the lower fulcrum bar jig binding bolt is arranged.

The described node A a of place to upper rack posts with can regulate the pole angle by rotating after lower fulcrum bar is connected by axis.

Described Node B is a upper rack posts length adjustment node, the length of regulating upper rack posts by some adjustment holes of upper rack posts.

Described node C is lower fulcrum bar and rod member for grid point of connection, the binding bolt of loosening lower fulcrum bar jig, and support can be by bearing parallel motion on rod member for grid.

The utility model has the advantages that: this hanger structure is simple, can regulate the pole angle by rotating after utilizing upper rack posts, lower fulcrum bar to connect by axis, support can be by bearing parallel motion on rod member for grid, easy to use, all finished by machinery in the whole lifting process, comparing with wheel crane does not need to increase in addition manpower.Duration is short, and expense is few, the about 3000-4000 of every cover suspender cost unit, and every cover suspender can repeatedly recycle.
