Description
Technical field
The present invention relates to a kind of cat ladder as construction aid, specifically, is that one kind is used for dry gas holder wall
The collapsible vertical ladder that plate is removed.
Background technology
Gas chamber is the steel vessel of storage industry and domestic gas, is widely present in iron and steel enterprise and coke-oven plant.Coal
Gas holder have dry type and wet type point, dry gas holder typically has the systems such as cabinet top, cabinet, piston, bottom of cabinet and elevator, wherein cabinet
System is shell vertical cylinder regular polygon structure, is typically made up of claustra, wallboard, H profile steel column and angle stiffener etc..
Dry gas holder cabinet wall is removed, and is using successively from top to bottom（Claustra）Block-by-block stepping gas cutting, large-scale crane block-by-block
Lift what is removed by post, that is, before wallboard is removed in lifting, circulation of qi promoting need to be entered between lower wall panels on annular vestibule H profile steel column
Cut wallboard operation.
Conventional gas cutting wallboard operation is between upper and lower two claustra（Highly 10～15m）, install and directly climb with what arc was leaned against
Ladder removes personnel up and down as gas cutting and the foothold of Job Operations.Due to vertical ladder, to step on stress surface at foot narrow, and not in cat ladder
Sole is stepped in upper installation, therefore during gas cutting dismounting wallboard, high labor intensive, working environment are bad, and work efficiency is extremely low, and safety is obtained not
To fully guarantee.
As gas chamber is superelevation, thin-walled, massive structure, every layer of claustra H profile steel gas cutting position, installation is all needed to lean against
Formula guarding cage vertical ladder, material consumption are more, make, the set-up time it is long, installation difficulty and need large-scale crane to coordinate to carry out；On cat ladder
Artificial gas cutting wallboard, by the mutually restricted influence such as cat ladder installation, wallboard gas cutting, lifting dismounting, causes the utilization rate of large-scale crane
It is extremely low, Demolition Construction high cost.
Using on gas chamber annular claustra, the new technology that hydraulic lifter removes wallboard is installed, certain office is there is also
It is sex-limited.No claustra platform under gas chamber ground floor wallboard, and H profile steel upright post basic and base plate platform are located at different level section,
Displacement every time needs crane lifting to coordinate, and causes the movement inconvenience of hydraulic lifter annular horizontal；Top layer wallboard corridor next time, due to installing
The adnexaes such as exhaust stack, fuel tank, its width are compared with other layer of claustra narrow；To meet hydraulic lifter stability, its width is basis
Other wider layer claustra modular in design, therefore on this layer of claustra, horizontal translocation elevator is manually unable to next setting, in ring
Move horizontally on shape claustra platform and installation is vertically moved and between upper and lower two claustra, all need large-scale crane to coordinate and can just complete.
Therefore, gas chamber wallboard is removed, and no matter protects cage cat ladder erect-position autogenous cutting, or hydraulic lifter gas using known
Cut method, all there are problems that above-mentioned a variety of limitations and.
The content of the invention
The purpose of the present invention, be propose it is a kind of it is safe and reliable, can recycle, conveniently moving, can be used for dry type coal gas
The collapsible vertical ladder that cabinet wallboard is removed.
For achieving the above object, technical solution of the invention is：
A kind of collapsible vertical ladder removed for dry gas holder wallboard, dry gas holder are provided with eight layers of annular claustra platform,
10-15m is highly reached between upper strata claustra platform and lower floor's claustra platform, including vertical ladder ladder body unit, vertical ladder top are fixed
Unit, vertical ladder bottom fixed cell, it is characterised in that：
The vertical ladder ladder body unit includes four steel wire ropes and several square steel frames, and several square steel frames are in
Stereo structure is upper and lower to be stacked, and four steel wire ropes are respectively perpendicular the corner for being arranged at square steel frame, and are fastened with rope cramp,
Separately 500mm between two neighboring square steel frame, square steel frame are made by round steel；
Wherein：The diameter of four steel wire ropes is 8mm, and every steel wire rope upper end is coiled into ring junction, and with two rope cramps
Clamp fixation；Each square steel frame is the lead frame that 560*560mm is made with Φ 10mm round steel, square steel frame
Corner is respectively welded and fixed one piece of plain washer, and the other end of steel wire rope is returned after bypassing plain washer endoporus again and is wound on shape on steel frame round steel
Into Chinese lute section, and fix locked with rope cramp below steel frame, make each steel wire rope between two square steel frames
Distance keeps constant, and can connect upper and lower square steel frame；Respectively pacify on the corresponding both sides round steel of each square steel frame
The operating pedal that one piece of width is 80mm is filled, in the left and right sides of operating pedal, between operating pedal and round steel, with two width spacing
200mm, the hinge of long 65mm are welded to connect, and operating pedal inner side edge welds the Φ 10mm round steel of a long 580mm, operating pedal
When putting down, the long 580mm round steel is placed on before and after vertical ladder on round steel, forms good footboard；
Vertical ladder top fixed cell, is fixed on the upper strata claustra platform of H profile steel column, according to the width of vertical ladder
Degree arranges corresponding four installing holes, two seamless steel pipes of horizontal positioned beside four installing holes；When on every steel wire rope
When end is coiled into installing hole of the ring junction from below the claustra platform of upper strata and passes, steel wire of the every seamless steel pipe from two steel wire ropes
Pass through in knot, the gravity of vertical ladder is respectively undertaken on the claustra platform of upper strata；
Vertical ladder bottom fixed cell includes chain block, tenses hanger, in the square steel framework of the bottom of vertical ladder
At left and right sides round steel on frame, 2 chain blocks are respectively hung, chain block hook is welded on the claustra platform of bottom, fastening is hung
Ear tightens up chain block, and flexible vertical ladder is changed into semi-rigid vertical ladder, removes for dry gas holder wallboard；Cabinet wallboard is torn open
After removing, vertical ladder can be put down recovery and be overlapped and be stacked.
The collapsible vertical ladder removed for dry gas holder wallboard of the present invention, can also adopt following technical measures
Further to realize.
The collapsible vertical ladder of dry gas holder wallboard dismounting is previously described for, wherein the specification of the installing hole is 400*
The cat ladder installing hole of 400mm.
The collapsible vertical ladder of dry gas holder wallboard dismounting is previously described for, wherein the specification of the seamless steel pipe is Φ
48*3.5mm steel pipes.
The collapsible vertical ladder of dry gas holder wallboard dismounting is previously described for, wherein the specification of the chain block is 1t
Chain block.
After above-mentioned technical proposal, the present invention for dry gas holder wallboard remove collapsible vertical ladder with
Lower advantage：
