Description

For tower boiler heating surface column pipe bracing means

Technical field:

The utility model relates to one kind to be used for tower boiler heating surface column pipe bracing means.

Background technique:

The entire heating surface of tower boiler is suspended on furnace roof large girder by column pipe, the quality of column pipe quality of connection The safe operation and heating surface service life of boiler are directly influenced, all heating surfaces of existing tower boiler are suspended in It is connected on column pipe superheater, and the sunpender by passing through furnace roof is suspended on large girder, column pipe and panel-pipe of heating surface Between fixation device run under boiler long term high temperature hyperbaric environment after it is easy to appear problem, specific defect shows as column pipe It is not fixed firmly pipe between causing column pipe and pipe to arrange with institute's clamp row, phenomena such as machinery touches mill, pipe dissipation frame falls off occurs, seriously When directly contribute heating surface tubes in boilers booster, influence the safe and stable operation of boiler.

Summary of the invention:

In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide one kind to be used for tower boiler Heating surface column pipe bracing means, this is used for, and tower boiler heating surface column pipe bracing means is conducive to improve column pipe and pipe is arranged Support effect, what is both avoided touches mill or phenomena such as pipe dissipation frame falls off.

The utility model is used for tower boiler heating surface column pipe bracing means, it is characterised in that: is fixed on including upper end On tower boiler furnace roof large girder and vertically arranged column pipe, pipe row, the column pipe are laterally placed on the column pipe On be arranged at intervals with several anchor ears, the anchor ear includes two opposite U-tube hoops that setting is welded and fixed, and column pipe is located at U The slot bottom of shape pipe collar, the lower bottom part of the U-tube hoop are welded with backing plate, are equipped between two column pipes and assemble shape by two support chips At backplate, the support chip has an arc groove, and the arc groove of two support chips is oppositely arranged to form the circle of banding pipe row The round hole upper and lower in shape hole, the backplate is fixed with baffle.

Further, the end of above-mentioned U-tube hoop is oblique, to form V-arrangement weldering when two U-tube hoops are oppositely arranged Access slot.

Further, the circumference of above-mentioned baffle is welded on backplate, to realize the fixation of two support chips on backplate.

Further, the upper end of above-mentioned backplate is welded on the bottom of backing plate.

Further, the lower part of above-mentioned column pipe has round part and arranges parallel horizontal part with pipe.

Further, the horizontal part of above-mentioned column pipe is equipped with anchor ear, and the top of the column pipe is equipped with anchor ear.

The utility model installs U-shaped by arranging clearance position in pipe for tower boiler heating surface column pipe bracing means Pipe collar welds, gapless between U-tube hoop and pipe array of pipes after holding left and right two column pipes tightly, and avoid the two touches mill or pipe Phenomena such as dissipation frame falls off.

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Specific embodiment:

In order to make the above-mentioned features and advantages of the utility model more obvious and understandable, special embodiment below, and cooperate attached drawing, It is described in detail below.

The utility model includes that upper end is fixed on tower boiler furnace roof for tower boiler heating surface column pipe bracing means On large girder 1 and vertically arranged column pipe 2, it is laterally placed with pipe row 3 on the column pipe 2, is spaced and sets on the column pipe 2 Several anchor ears 4 are equipped with, the anchor ear 4 includes two opposite U-tube hoops 5 that setting is welded and fixed, and column pipe is located at U-tube hoop 5 slot bottom 6, the lower bottom part of the U-tube hoop 5 are welded with backing plate 7, are equipped between two column pipes 2 and assemble shape by two support chips 8 At backplate 9, the support chip 8 has an arc groove 10, and the arc groove of two support chips is oppositely arranged to form banding pipe row Round hole 11, the round hole upper and lower of the backplate is fixed with baffle 12, which uses for fixing U-tube hoop 5 In backplate 9 is welded and fixed, which is used to wear the pipe of pipe row 3.

Further, in order to design rationally, the end of above-mentioned U-tube hoop is oblique, to set relatively in two U-tube hoops V-arrangement welding groove 13 is formed when setting, and two U-tube hoops being oppositely arranged are welded and fixed well by V-arrangement welding groove 13.

Further, in order to fixed, the circumference of above-mentioned baffle 12 is welded on backplate 9, and is located at upper and lower adjacent circle Between shape hole 11, to realize the fixation of two support chips on backplate.
