Abstract
A vertical expansion controller for a coke oven comprises essentially spring housings (4) with pre-tightening force, a spring baseboard (5), a spring pressing board (6), a pusher (9), screw nuts (7) and top guide screws (8), which is characterized in that the multiple spring housings (4) are all fixed to the spring baseboard (5). The other ends of the spring housings (4) are fixed to the spring pressing board (6), which is drilled, with round holes relative to the spring housings (4). Piercing through the round holes, the top guide screws (8) with screw nuts (7) are arranged in the spring housings (4). The other ends of the top guide screws (8) are fixed to the pusher (9). Then, the controller (10) is made. When used, multi-groups of the controllers (10) are arranged symmetrically between a resistance wall (12) and an oven platform (13) on the two ends of the coke oven (11). The screw nuts (7) are regulated in a rotating way. The spring housings (4) are compressed. An elastic reduction pressure opposite to the coke oven vertical expansion force is provided for the coke oven (11) by the resistance wall (12) to prevent the coke oven (11) from vertical expansion.
Description
Technical field
The utility model belongs to the protecting coke oven equipment technical field, relates in particular to a kind of device of controlling the coke oven longitudinal dilatation.
Background technology
The longitudinal dilatation amount of coke oven is one of most important index of weighing the coke oven life-span, wants to prolong the work-ing life of coke oven, just must delay its longitudinal dilatation speed.The prior art method that longitudinal dilatation is taked to the restriction coke oven is that vertical furnace retaining tie rod is set at the two ends of coke oven, because vertically the furnace retaining tie rod lacks flexible, after coke oven masonry generation longitudinal dilatation, can not provide enough outer devote every effort to help its set back, can only limit the longitudinal dilatation of coke oven body to a certain extent, more seriously vertical furnace retaining tie rod is because of long-term tension power effect, easy fracture failure, in case vertically can not get timely replacing behind the furnace retaining tie rod fracture failure, can only limit the longitudinal dilatation of coke oven masonry by resistance wall, can cause the obliquity of resistance wall to increase if things go on like this, aggravation coke oven masonry generation faulting of slab ends damages until masonry.
The utility model content
The purpose of this utility model provides a kind of coke oven longitudinal dilatation control device that longitudinal dilatation Flexible Reset pressure is provided to the coke oven masonry that has, and solving because of coke oven longitudinal dilatation excessive velocities, and shortens the problem in coke oven life-span.
The technical solution of the utility model is:
Coke oven longitudinal dilatation control device, mainly comprise spring housing, spring seat board, spring bearer plate, push pedal, nut and jackscrew bar, it is characterized in that evenly being fixed in a plurality of spring housings on the spring seat board, the other end of spring housing is fixed on the spring bearer plate, have on spring bearer plate and the corresponding circular hole of spring housing, the jackscrew bar that will have nut penetrates circular hole and places in the spring housing, and the other end of jackscrew bar is fixed in the push pedal, tune nut, the parallel distance between adjustable springs seat board and the push pedal.
During use, above-mentioned a plurality of coke oven longitudinal dilatation control device are symmetrically placed between the resistance wall of coke oven both sides and stove between the platform, tune nut, spring housing is compressed, the bounce of its generation tightly pushes up spring seat board and push pedal to expand between coke oven resistance wall and stove between the platform, provide and the opposite restorer of coke oven longitudinal dilatation power to the coke oven masonry by the coke oven resistance wall, to stop the longitudinal dilatation of coke oven.
Further, described spring housing is the big spring with compression preliminary tension of two ends band backing plate.
Can provide enough elastic restoring forces that is directly proportional with coke oven longitudinal dilatation power size to the coke oven resistance wall in real time owing to have the spring housing of preliminary tension in this device, so longitudinal dilatation that can effectively stop or slow down the coke oven masonry, avoid the damage of coke oven masonry, prolong the coke oven purpose in work-ing life thereby reach.

Embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 2, the big spring 1 two ends square backing plate 2 of burn-oning, to the elastic force that produces about 12 tons, promptly make spring housing 4 in four jiaos of corresponding welding lacing wires 3 of upper and lower backing plate 2 then with preliminary tension with screw block compression big spring 1.
Coke oven longitudinal dilatation control device as shown in Figure 1, three groups of spring housings 4 evenly are fixed on the spring seat board 5 that channel-section steel makes, the other end of spring housing 4 is fixed on the spring bearer plate 6 that channel-section steel makes, on spring bearer plate 6, bore and open and spring housing 4 corresponding circular holes, the jackscrew bar 8 that will have nut 7 penetrates circular hole, place in the spring housing 4, the other end of jackscrew bar 8 is fixed in the push pedal 9 that channel-section steel makes, and promptly makes coke oven longitudinal dilatation control device 10.Tune nut 7, the parallel distance between adjustable springs seat board 5 and the push pedal 9.
As shown in Figure 3, during use, between the resistance wall 12 at coke oven 11 two ends and stove between the platform 13 respectively symmetry lay four groups of coke oven longitudinal dilatation control device 10, confirming to remove lacing wire 3 after it installs firmly, tune nut 7, spring housing 4 is compressed, and the bounce of its generation tightly pushes up spring seat board 5 and push pedal 9 to expand between coke oven resistance wall 12 and stove between the platform 13.By tuning nut 7; every group of coke oven longitudinal dilatation control device 10 can provide 25～35 tons pressure; the resistance wall 12 of coke oven 11 can be subjected to 100～140 tons protectiveness elastic pressure; this pressure passes to coke oven 11 by resistance wall 12; for the coke oven masonry provides the elastic reset power opposite with longitudinal dilatation power, to stop the longitudinal dilatation of coke oven 11.
