Description
Technical field
The utility model relates to a kind of combined large blast furnace cooling stave installation auxiliary device, relates in particular to a kind of large blast furnace cooling stave that is applicable to the drawing device that hangs of the outer little job space of stove is installed.
Background technology
At present, for the large blast furnace equipment installation project all have the duration short, workload is big, working face is little, safety and specification of quality be than characteristics such as height; For guaranteeing both quality and quantity to finish smoothly each task, press for and improve existing mounting process, improve work efficiency.It is working procedure comparatively crucial in the blast-furnace equipment installation work that blast furnace cooling stave is installed, and its installation quality and speed directly affect the quality and the duration of engineering.The installation of blast furnace cooling stave mainly comprises: lifting, in place and adjustment.
In place and adjust at cooling stave, generally be to utilize crane in the blast furnace, lead chain and the people pushes away in place pickaback by existing traditional construction technology.It has the following disadvantages: (1) take a lot of work, dangerous; General large blast furnace cooling stave is of a size of 1000*500*3000 (the thick * height of wide *), and weight heavier (its weight is generally in 3T to 5T scope), therefore needs to drop into more man power and material in the installation process of cooling stave; In the construction, operation on the service platform in blast furnace, the workmen will prevent that not only cooling stave from wounding, and will prevent also that simultaneously the underfooting object from mixing down, and also will concentrate strength on making cooling stave in place, this has brought inconvenience also to bring very big potential safety hazard simultaneously to construction.(2) be unfavorable for the protection of finished product, all will carry out the pressure testing experiment before and after blast furnace cooling stave is installed, its apparatus body and water pipe are all forbidden to collide energetically; Therefore in the stove many people operation strength unstable etc. very easily with equipment and furnace shell damaged in collision.(3) the construction operation face is little, and general blast furnace diameter is about 8-12 rice, and blast furnace cooling stave is installed on the platform of all setting up in blast furnace and carried out, it is very narrow that the monolithic cooling stave is installed its scope of operation, is not suitable for operation in many people stove, is subjected to the restriction of construction operation face, easily cause the work holdup, delay the construction period.(4) operating efficiency, quality can not guarantee; Because large blast furnace cooling stave quality is all very heavy, in stove, utilize manpower to install, not only inefficiency is dangerous, and cooling stave is also wayward with the furnace shell gap, is difficult to the assurance construction quality.
According to the characteristics of cooling stave constructional method, also once outside blast furnace, used and lead chain and hang on the platform, chain passes the method that the water pipe eyelet welding is connected on the water pipe and installs, but not being every layer of cooling stave, the platform sling point do not have, and highly also not parallel, chain is welded on hell to pay on the water pipe in addition, and program is loaded down with trivial details.Therefore, at the mounting condition of present large blast furnace cooling stave, need exploitation to be adapted to the blast furnace cooling stave installation auxiliary device of the outer little job space of stove.
The utility model content
The purpose of this utility model is in order to overcome existing drawback in the above-mentioned prior art, and a kind of easy to operate, high efficiency, high safety, built-up type blast furnace cooling stave installation auxiliary device with low cost are provided.
In order to solve the problems of the technologies described above, the technical scheme that the utility model built-up type blast furnace cooling stave installation auxiliary device is achieved is, a kind of combined large blast furnace cooling stave installation auxiliary device, comprise lifting appliance and hang to draw and use fixed support, described fixed support is made of an inverse-T-shaped crossbeam and a top column and two lower pole of being connected on the described crossbeam, and described inverse-T-shaped crossbeam is provided with lifting appliance.
Described top column is a retractor device, can be the setting of a bolt or other adjustable lengths.Described top column is fixedlyed connected with described crossbeam.Described lower pole and described crossbeam are slidingly connected for the bolt indentation formula.Be provided with two inclined support bars between described inverse-T-shaped two crossbeams, also be provided with inclined support bar between top column and crossbeam.Described lifting appliance is led chain end and is provided with expansion bolt for leading chain.
The utility model compared with prior art its beneficial effect is: the utility model hangs to draw with fixed support and lifting appliance combination and is provided with, wherein, support bracket fastened lower prop adopts slidably and connects, and can adjust the pillar distance and insert in the water pipe fixedly entire bracket according to lower floor's cooling stave water pipe spacing; The top column can utilize bolt to regulate its length setting, so that along with the support angle is adjusted at the last furnace shell angle of inclination, is convenient to workmen's operation, need not many people operation, and the safety coefficient height; Lifting appliance is led chain end and is provided with expansion bolt, can be good at being connected with water pipe, and conveniently adorns, tears open; The utility model is simple in structure, and is easy to operate, safe and reliable, higher to the protectiveness of product; Make material of the present utility model and can make full use of scrap stock, cost of manufacture is cheap.
