Description
Technical field
The utility model relates to a kind of specific equipment that is used for transmitting on the coke oven furnace stay adjusting power, particularly a kind of coke oven furnace stay spring and holder combination thereof.
Background technology
Coke oven heating back furnace wall outwards expands, and bulging force is delivered on the furnace stay by protecting sheet, spring and spring suppport, by the reactive force that furnace stay produces bulging force is offset.Spring and spring suppport play crucial effects in this course.Spring on the coke oven furnace stay and support thereof normally carry out the more loaded down with trivial details difficulty of furnace stay upper springs and support thereof the installation and removal under high-altitude, hot environment respectively in order when installation and removal.In addition because in order to prevent spring by stove fire barbecue distortion and prevent that burnt dirt from entering gapping of spring, the spring outer setting spring shield, so the measurement of spring deflection is not accomplished all the time easy to be directly perceived.Usually the measuring method that adopts is to open a corresponding probe aperture on spring posterior bracket and furnace stay, probe is passed take out after furnace stay and spring posterior bracket touch the spring front carriage, and relatively preset initial value can draw the deflection of spring.
The subject matter that traditional spring and support thereof exist is:
1) the forward and backward support of spring and spring each integral part when installation and removal disperses, and carries inconvenience, long, contraposition connection difficulty of operating time;
When 2) adopting the deflection of probe measurement method measuring spring,, accurately prestressed and not directly perceived thereby influence adds because the influence that probes into angle and burnt dirt of probe causes measuring error bigger than normal.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provide a kind of back rational in infrastructure, capable of being combined complete installation dismounting, can outside directly the coke oven furnace stay spring and the holder combination thereof of measuring spring deflection.
For achieving the above object, the utility model is by the following technical solutions:
A kind of coke oven furnace stay spring and holder combination thereof, comprise spring shield and be installed in the spring assembly of spring shield inside, right-hand thread spring fore-stock, the right-hand thread spring back rest, the right-hand thread screw rod, left hand thread spring fore-stock, left hand thread spring back rest and left hand thread screw rod, the right-hand thread screw rod passes through its screw thread successively with the dextrorotation spring back rest, spring assembly and dextrorotation spring fore-stock connect into an integrally combined, the left hand thread screw rod passes through its screw thread successively with the left-handed spring after poppet, spring assembly and left-handed spring fore-stock connect into another integrally combined, and spring and holder combination thereof are installed on each line stress point of coke oven furnace stay.
Be provided with bar hole in the flexible direction of spring shield upper edge spring assembly, and be provided with graduated scale, on spring fore-stock and spring back rest, be provided with outstanding measurement ear, measure ear and stretch out from the tapping on the spring shield at tapping.
Spring assembly is made up of spring or butterfly spring.
Compared with prior art, the beneficial effects of the utility model are:
1, owing to adopted the integrally combined of spring and support thereof, reduces the operating time of installation and removal, improved working efficiency.
2, can outside directly measuring spring deflection, take off data is intuitive and reliable.Reduced the maintenance personnel operation easier, improved the accuracy of measuring.

Among the figure: 1, right-hand thread spring fore-stock 2, spring assembly 3, right-hand thread screw rod 4, right-hand thread spring back rest 5, left hand thread spring fore-stock 6, left hand thread screw rod 7, left hand thread spring back rest 8, spring shield
Embodiment
See Fig. 1, coke oven furnace stay spring and holder combination thereof, be installed on each line stress point of coke oven furnace stay, form by right-hand thread spring fore-stock 1, spring assembly 2, right-hand thread screw rod 3, right-hand thread spring back rest 4, left hand thread spring fore-stock 5, left hand thread screw rod 6, left hand thread spring back rest 7.Right-hand thread screw rod 3 successively connects into an integrally combined with dextrorotation spring back rest 4, spring assembly 2, dextrorotation spring fore-stock 1 by its screw thread before installing; Left hand thread screw rod 6 successively connects into another integrally combined with left-handed spring after poppet 7, spring assembly 2, left-handed spring fore-stock 5 by its screw thread.During installation combination found accurately the installation site on furnace stay, with being connected of the 3 left-handed relievings of right-hand thread screw rod and right-hand thread spring fore-stock 1; With being connected of the 6 dextrorotation relievings of left hand thread screw rod and left hand thread spring fore-stock 5, prepare to enter the adjustment working order.
Working order when Fig. 2 represents coke oven furnace stay spring and holder combination employing spring thereof.Screw rod has separated with the spring fore-stock makes spring fore-stock measurement ear be positioned the A point, after spring is in zero load state of nature and writes down spring back rest original point C, right-hand thread screw rod 3 is continued the left-handed right-hand thread spring back rest 4 that makes to right-hand thread spring fore-stock 1 direction holddown spring group 2; Left hand thread screw rod 6 is continued dextrorotation makes left hand thread spring back rest 7 to left hand thread spring fore-stock 5 direction holddown spring groups 2.Measuring ear when spring back rest reaches B point and makes between B, the C point apart from presetting with spring and depress deflection and stop the rotation when identical and reach the theoretical stress value.Distance between B, the C point can directly be read according to the graduated scale of spring shield tapping in addition.
Working order when Fig. 3 represents coke oven furnace stay dish spring and holder combination employing dish spring thereof.Screw rod has separated with dish spring fore-stock makes dish spring fore-stock measurement ear be positioned the A point, after the dish spring is in zero load state of nature and writes down dish spring after poppet original point C, right-hand thread screw rod 3 is continued the left-handed right-hand thread dish spring after poppet 4 that makes compress dish spring group 2 to right-hand thread dish spring fore-stock 1 direction; Left hand thread screw rod 6 is continued dextrorotation makes left hand thread dish spring after poppet 7 compress dish spring group 2 to left hand thread dish spring fore-stock 5 directions.Measuring ear when dish spring after poppet reaches B point and makes between B, the C point apart from presetting with the dish spring and depress deflection and stop the rotation when identical and reach the theoretical stress value.Distance between B, the C point can directly be read according to the graduated scale of dish spring cover tapping in addition.
