Abstract
The utility model relates to a down-regulated hole screwing and sealing device for a down-regulated coke oven. The device comprises a retaining ring, a sealing cover, a connecting cover, a bolt, a rotary spanner and a beam, wherein the sealing cover is arranged at the lower part of a down-regulated hole for sealing the down-regulated hole and provided with the connecting cover, and the rotary spanner is connected with the bolt which is connected with connecting cover; lifting lugs are respectively arranged at both sides of the outer wall of the down-regulated hole, one end of the retaining ring is connected with the lifting lugs, the other end is connected with the beam, and both ends of the beam are respectively hung at the lower parts of the lifting lugs by the down-regulated hole by the retaining ring. The utility model has the advantages that the down-regulated hole screwing and sealing device for the down-regulated coke oven can be conveniently and rapidly mounted and dismounted, the working efficiency is greatly improved and the labor intensity of workers is lightened particularly under the circumstances that the coke oven in an underground gas operation area where the lighting is poor, each worker must raise the head to operate, and thousands of operations are needed for adjusting the whole oven once.
Description
Technical field
The utility model relates to a kind of down-adjusting hole tightening and sealing device for down-adjusting coke oven, and this device is installed on the downward modulation hole of down-regulation type coking furnace shaft bottom, and the screwing hermetic effect is played in the downward modulation hole.
Background technology
The down-regulation type coke oven is regulated by the area that changes grate brick adjustable port and is risen and the distribution of downdraft, guarantees that coke oven length is to the homogeneity that heats.This adjusting is operated in the coke oven vault and finishes, and regulates by the downward modulation hole that is positioned at the coke oven bottom.Need to open before adjusting work begins and after finishing and seal and reduce the hole.Coke oven adopted the nut sealing of DN100 herein in the past, and coke oven put into production after for some time, and owing to reasons such as burn into thermal expansions, the dismounting of the nut of sealing is difficulty relatively.Because every coke oven is provided with several thousand downward modulation holes, so the workload of dismounting sealing nut is very big.
Summary of the invention
The purpose of this utility model provides the down-adjusting hole tightening and sealing device for down-adjusting coke oven of a kind of easy installation and removal, simple in structure, good seal performance, solved the difficult problem of existing nut sealing dismounting, save the operating time greatly, alleviated labor strength.
The utility model is achieved through the following technical solutions:
A kind of down-adjusting hole tightening and sealing device for down-adjusting coke oven, this device comprises clasp, sealing cover, connection cover, screw rod, rotary spanner, cross bar, sealing cover is arranged on downward modulation bottom, hole and is used for sealing the downward modulation hole, on sealing cover, be provided with connection cover, rotary spanner is connected with screw rod, and screw rod is connected with connection cover; Be provided with hanger in downward modulation outer wall both sides, hole, clasp one end is connected with hanger, and the other end is connected with cross bar, and the cross bar two ends are lifted on the hanger bottom in downward modulation hole by clasp.
Be provided with gasket between the hole wall in described sealing cover and downward modulation hole.
Compared with prior art, the beneficial effects of the utility model are: can install quickly and easily and dismantle, especially in coke oven vault coal gas operating area, conditions such as daylighting are bad, the workman also must face upward the head operation, full stove is regulated under the situation of several thousand of less important operations, has improved working efficiency greatly, has reduced labor strength.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structure vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
See Fig. 1, Fig. 2, a kind of down-adjusting hole tightening and sealing device for down-adjusting coke oven, this device comprises clasp 3, sealing cover 4, connection cover 5, screw rod 7, rotary spanner 9, cross bar 6, gasket 8, sealing cover 4 is arranged on downward modulation 1 bottom, hole and is used for being provided with gasket 8 between the hole wall in sealing cover 4 and downward modulation hole 1 in sealing downward modulation hole 1.Be welded with connection cover 5 on sealing cover 4, rotary spanner 9 is welded to connect with screw rod 7, and screw rod 7 is connected with connection cover 5; Be provided with hanger 2 in downward modulation outer wall both sides, hole, clasp 3 one ends are connected with hanger 2, and the other end is connected with cross bar 6, and cross bar 6 two ends are lifted on hanger 2 bottoms in downward modulation hole 1 by clasp 3.
When this device is installed, gasket 8 is put well on sealing cover 4 in advance, then sealing cover 4 is faced toward downward modulation hole 1, two clasps 3 are suspended to respectively on the hanger 2, tighten rotary spanner 9 clockwise, in the rundown process, move on the screw rod 7, withstand sealing cover 4 and compress the downward modulation hole, cross bar 6 is being with clasp 3 to move down simultaneously, up to fastening hanger 2; When dismantling this device, unclamp rotary spanner 9 in the other direction, screw rod 7 moves down, and is being with connection cover 5 and sealing cover 4 to move down together, upwards pushes away whole device, and clasp 3 is unloaded from hanger 2, like this complete assembly is pulled down.
