Description
Technical field
The utility model belongs to machine industry equipment hoisting field.
Background technology
In petroleum chemical industry, large scale equipment is to ensure scene smoothly installation, and manufactory, which must provide, hangs lid lifting lug etc.
Hoisting tool.Then it is that every equipment is equipped with a set of special, no versatility if big thickness hangs lid；If lifting lug is then to set
It must be welded on equipment body before standby manufacture, the stress distribution of apparatus casing will be changed in this way, it is harmful to equipment.Sometimes it is setting
The interim lifting lug of standby case weld cuts off lifting lug after the completion of lifting, and the polishings such as the crator of surface of shell, slag is removed and are done again
Only, workload is very big, certainly this equipment required only for no heat treatment.In addition, select interim lifting lug material and
Welding material must be matched with case material, and require thorough cleaning surface of shell after removing, and arc crater must not be caused to shell, is split
The defects of line.In short, prior art tedious process, working efficiency is low, does not have versatility.
Invention content
We will solve the problems, such as：It is auxiliary to overcome the limitation of the prior art, designing and manufacturing a kind of big equipment lifting
Help device.
The utility model provides a kind of big equipment installation hoisting tool in scene, and structure is by two lifting lug cage plates 1 and silk
Thick stick 2, nut 3, bolt 4 form；The lifting lug cage plate 1 is manufactured with steel plate, and centre opens up rectangular sets of holes, length and
Width is adapted with large flange disk 7 at the top of equipment；1 top of lifting lug cage plate has main hanging hole 5, side to have side lifting hole(eyelet) 6 one, lead screw hole
Four；Two lifting lug cage plates 1 are connected by leading screw 2, nut 3 using bolt mode when use, and bolt 4 is used in combination to fix.
It is all made of carbon steel making with upper-part.
Live big equipment installation hoisting tool is as follows using program：
1. two 1 slots of lifting lug cage plate are inserted in respectively and block 7 both ends of large flange disk at the top of equipment；
2. four leading screws to be passed through to the lead screw hole of lifting lug cage plate 1 in device, 3, both ends nut fastens；
3. bolt 4 to be inserted into the bolt hole for stretching out large flange disk 7 at the top of 1 equipment outside lifting lug cage plate, lifting lug cage plate is blocked
1, bolt is snarled with flexible material to protect flange bolt hole inner wall；
4. it is main stress point that main rope, which passes through main hanging hole 5, auxiliary steel wire rope passes through 6 control device lifting side of side lifting hole(eyelet)
It deflects to equipment is prevented；
5. overhead traveling crane is slowly promoted, control direction is steadily lifted by crane；
6. after the completion of lifting, removing bolt 4, unscrewing both sides nut 3, lifting lug cage plate 2 is radially exited along flange, dress is removed
It sets.
The utility model has the beneficial effects that：The device has versatility, suitable for having at the top of arbitrary general nominal diameter
The equipment of large flange.It is active connection between equipment, to apparatus body fanout free region.The apparatus structure is simple, easy to operate,
Manufacturing cost is low.

In figure：1 lifting lug cage plate, 2 leading screws, 3 nuts, 4 bolts, 5 main hanging holes, 6 side lifting hole(eyelet)s, 7 equipment top large flange disk.
Specific implementation mode
The utility model is further described in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, a kind of big equipment in scene installs hoisting tool, and structure is by two lifting lug cage plates 1 and leading screw
2, nut 3, bolt 4 form；The lifting lug cage plate 1 is manufactured with steel plate, and centre opens up rectangular sets of holes, length and width
Degree is adapted with large flange disk 7 at the top of equipment；1 top of lifting lug cage plate has main hanging hole 5, side to have side lifting hole(eyelet) 6 one, lead screw hole 4
It is a, as shown in Figure 3；Two lifting lug cage plates 1 are connected by leading screw 2, nut 3 using bolt mode when use, and bolt 4 is used in combination to fix,
As shown in Figure 1.
It is all made of carbon steel plate manufacture with upper-part.
Live big equipment installation hoisting tool is as follows using program：
1. two 1 slots of lifting lug cage plate are inserted in respectively and block 7 both ends of large flange disk at the top of equipment；
2. four leading screws to be passed through to the lead screw hole of lifting lug cage plate 1 in device, 3, both ends nut fastens；
3. bolt 4 to be inserted into the bolt hole for stretching out large flange disk 7 at the top of 1 equipment outside lifting lug cage plate, lifting lug cage plate is blocked
1, bolt is snarled with flexible material to protect flange bolt hole inner wall；
4. as shown in figure 4, it is main stress point that main rope, which passes through main hanging hole 5, auxiliary steel wire rope is controlled across side lifting hole(eyelet) 6
Equipment lifting direction prevents equipment from deflecting；
5. overhead traveling crane is slowly promoted, control direction is steadily lifted by crane；
6. after the completion of lifting, removing bolt 4, unscrewing both sides nut 3, lifting lug cage plate 2 is radially exited along flange, dress is removed
It sets.
Pressure vessel is contemplated that in the design by the device seriation, increases its versatility, reduces manufacturing cost.
