Abstract
The utility model provides a professional instrument is used in hoist and mount of large capacity coke oven furnace gate, the instrument main part is a dop, and this dop is by upper and lower steel sheet and is used for the connector plates who connects upper and lower steel sheet to constitute, and upper and lower steel sheet parallel arrangement makes the dop be " (img file='DDA0000721251940000011. TIF'wi='46'he='60' /) " form, the furnace gate stretches into the recess that forms between the upper and lower steel sheet in, stove doorjamb upper portion horizontal plane is connected through the type high strength bolt that shears with last steel sheet, the welding has the hoist and mount lug on going up the steel sheet. The utility model discloses can be safely, hoist the large capacity coke oven furnace gate fast to the component can not damaged to simple structure, equipment convenience.
Description
Technical field
The utility model belongs to coker field engineering field, relates to a kind of large capacity coke oven fire door lifting professional tool.
Background technology
Along with social development, coker is larger towards volume, the heavier future development of equipment.Former coke oven door equipment, when lifting, adopts following two kinds of methods usually: 1, utilize two that door upper part is reserved
25 bolt hole hold-down bolts are connected with steel rope and lift, and bolt, once cross major rupture by shearing force, severe safety accident will occur.2, adopt steel rope fire door entirety to be pulled, due to steel wire lifting poor stability, steel rope affects by angle and construction weight, the fragile element of installation corner of steel rope.
Summary of the invention
The purpose of this utility model is to provide a kind of large capacity coke oven fire door lifting professional tool, and this instrument can lift large capacity coke oven fire door safely and fast, and structure is simple, easy to assembly, can not damaged member.
As above conceive, the technical solution of the utility model is: a kind of large capacity coke oven fire door lifting professional tool, is characterized in that: tool body is a dop, and this dop is made up of with the junction steel plate for being connected upper and lower steel plate upper and lower steel plate, upper and lower steel plate be arranged in parallel, makes dop be
shape; Fire door stretches in the groove that formed between upper and lower steel plate, and fire door frame top water plane is connected by resisting shear type high strength bolt with dop upper steel plate; Described dop upper steel plate is welded with lifting hanger.
The groove size formed between above-mentioned upper and lower steel plate and fire door size match.
Above-mentioned upper steel plate is welded with stiffened steel plates.
The utility model has following advantage and good effect:
1, the utility model utilizes resisting shear type high strength bolt to pass prepared screw-bolt hole on dop and fire door frame, and by dop and fire door frame connection control, it moves, and can lift, can not damage fire door knife edge.
2, the utility model is double insurance fixture, dop and resisting shear type high strength bolt is utilized to bite fire door frame, solve the bias of fire door suspension centre in hoisting process, even if occur that the situation that high strength bolt ruptures also installation accident can not occur, also can prevent dop from departing from, thus ensure that lifting is safer, more stable, solve and adopt single bolt as screw thread dropout phenomenon can occur during suspension centre.
Accompanying drawing explanation
Fig. 1 is lateral plan of the present utility model;
Fig. 2 is birds-eye view of the present utility model;
Fig. 3 is front view of the present utility model.
In figure: 1, resisting shear type high strength bolt, 2, lifting hanger, 3, hole for hoist, 4, stiffened steel plates (25mm), 5, fire door frame, 6, dop, 7, fire door frame prepared screw-bolt hole.
Detailed description of the invention
As shown in the figure: a kind of large capacity coke oven fire door lifting professional tool, tool body is a dop 6, and this dop is made up of with the junction steel plate for being connected upper and lower steel plate upper and lower steel plate, and upper and lower steel plate be arranged in parallel, makes dop be
shape; Fire door stretches in the groove that formed between upper and lower steel plate, and fire door frame 5 top water plane is connected by resisting shear type high strength bolt 1 with dop upper steel plate; Described dop upper steel plate is welded with lifting hanger 2.The groove size formed between above-mentioned upper and lower steel plate and fire door size match.Above-mentioned upper steel plate is welded with stiffened steel plates 4.
Assembling of the present utility model, working process are:
1, dead work: first prepare two resisting shear type high strength bolts 1, and utilize 50mm Plate Welding one dop 6, and two bolt mounting holes are bored on dop, the groove size formed between the upper and lower steel plate of dop and fire door size match.
2, the suspender welded and fire door frame 5 are assembled, and ensure that resisting shear type high strength bolt 1 is corresponding with prepared screw-bolt hole on fire door 7 position.
3, install resisting shear type high strength bolt 1, ensure bolt and internal thread screw thread fully fixing.
4, by the hole for hoist 3 on ready steel wire penetrating lifting hanger 2, coke oven for iron component check after slinging without exception after deliver to coke oven designated mounting position.
