Wherein, Part I promotes basis, is made up of multiple liftings basis 1.In the utility model, promote basis 1 and made by method below:
First method: pre-buried steel seat or bolt on cement concrete; Generally refer to pre-buried steel seat or pre-embedded bolt on the cement concrete of silo bottom.
Second method: at the upper welding of steel structure (structure of silo is steel structure) bracket, that is to say and weld bracket (fixed mount that has Plate Welding to become) composition on silo bottom or silo.
Part II is hoisting bracket, and hoisting bracket mainly comprises that some root posts, some support and multiple suspension centres, many diagonal braces.
Particularly, some root posts are evenly arranged in silo and enclose, and the bottom welding of every root post is on corresponding lifting basis 1.Support 3 and link together by steel plate 8 and the end of column 2, support 3 and column 2 be welded on respectively on steel plate 8, suspension centre 7 is arranged on steel plate 8, has steel plate 7 in the welded top of every root post 2.
And, between adjacent column respectively by supporting connection; And, in silo, enclose between the column at same diameter two ends and support connection by two respectively; Wherein, support on the steel plate at the top that is welded on column, two connect by junction steel plate between supporting.
It should be noted that, from Fig. 1 and Fig. 2, can find out, between adjacent column, respectively by supporting connection, forming a hexagonal column (is six roots of sensation column in the specific embodiment of Fig. 1, in the utility model, determine the quantity of column according to the size of silo and weight).Column 2 and three support (two support 3, one and support 3 ') and are connected by steel plate 8, and wherein, two support 3 columns 2 adjacent with column 2 respectively " with column 2 ' " be connected by steel plate; Support 3 ' by junction steel plate 6 with support 3 " be connected; Support 3 " be connected with column 2 ' by steel plate; And column 2 and column 2 ' are at the two ends of same diameter.
That is to say, supporting between all columns that enclose in silo and column is connected to form a hexagonal column, as shown in Figure 1, column 2 and column 2 " and column 2 ' " between support 3 by two and be connected, and support 3 with together with Plate Welding on column; And, column 2 with the column 2 ' of column 2 on same diameter by support 3 ' and support 3 " be connected; support 3 ' and support 3 " between connect by junction steel plate 6, and support on the steel plate that one end of 3 ' is welded on column 2 tops (welded top one block plate of every root post), support 3 " one end be welded on the steel plate at column 2 ' top.Hoisting bracket has just formed a firm support like this.
Column with support the structure being connected, can make hoisting bracket more firm, in the time of lifting heavy, hoisting bracket can not tilt easily, has promoted stability and rigidity compared with traditional structure.
In addition, it should be noted that, every root post connects by described junction steel plate between the column of the other end of same diameter.That is to say, at column 2 and column 2 " between also can directly be connected with junction steel plate or steel rope, so also can play the effect of hoisting bracket improving stability.
All columns and be connected the supporting side column in composition between column, that is to say, column with support between interconnect, be that each column is connected to the same, an entirety of whole bont formation; And the bottom of all columns is connected with lifting basis; Hoisting bracket and lifting basis composition rock-steady structure like this, this project organization can promote stability and the rigidity of whole bont.
Preferred embodiment of the utility model in the time that the weight quality that will promote is excessive, can arrange diagonal brace between column; One end of diagonal brace is welded on silo bottom, and the other end of diagonal brace is welded on the top of column; Diagonal brace can make the more stable of bont, is not easy to topple over.
Part III is weight-lifting equipment, and weight-lifting equipment 4 is arranged on the suspension centre 7 on steel plate 8.The quantity of weight-lifting equipment 4 is identical with the quantity of the column in Part II, on each column, be welded with a steel plate, on steel plate, be provided with a suspension centre, on each suspension centre, be provided with a weight-lifting equipment, so the quantity of weight-lifting equipment equates with the quantity of column.
Weight-lifting equipment can be chain block, electric block or hydraulic jack etc.In the utility model, can determine and use which kind of weight-lifting equipment according to the particular case of the weight that will promote.Chain block is applicable to handling midget plant and goods, and hoisting capacity is generally no more than 100 tons; Electric block is a kind of extraordinary weight-lifting equipment, and hoisting capacity is generally 0.1~80 ton, and lifting altitude is 3~30 meters; Hydraulic jack is applicable to the highly little various hoisting operations of lifting, the general heavier object of lifting.
Weight-lifting equipment 4 is hung on suspension centre by steel chain, and then weight-lifting equipment is connected with weight by the hanger of weight, thereby weight is mentioned.
Above-mentioned is the total of the utility model bont, and bont of the present utility model is compared with traditional center mast lift-on/lift-off system, and resistance to overturning is better, on circumferencial direction to weight highly regulate convenient.
To describe the process of interior side column flip-clip bont lifting silo of the present utility model in detail below, detailed process is as follows:
First assemble the first segment cylindrical shell of silo,
Then the weight-lifting equipment in interior side column flip-clip bont is connected with the bottom of the first segment cylindrical shell assembling, and after having connected, first segment cylindrical shell is promoted, and is promoted to default position;
Secondly the second section cylindrical shell of assembling silo, wherein, by the top weld together of the bottom of first segment cylindrical shell and second section cylindrical shell;
Then the weight-lifting equipment in side column flip-clip bont is connected with the bottom of the second section cylindrical shell assembling, and after having connected, the entirety to second section cylindrical shell together with first segment barrel soldering promotes, and is promoted to default position;
Then repeat the process of installing, welding and promoting, until whole silo installation.
Above-mentioned is the whole flow process that interior side column flip-clip bont promotes assembling silo.From said method, can draw, interior side column flip-clip bont resistance to overturning is better, on circumferencial direction to silo highly regulate on freely convenient.
Can find out by above-mentioned embodiment, the interior side column flip-clip bont that the utility model provides, each column supports and connects as one with each, can improve integrally-built stability and rigidity; Bont of the present utility model is simple in structure, easy to operate, safe, efficient.
