[0036] In some embodiments of the utility model, a groove adapted to the base 701 is provided on the top plate 2 , which can help the jack 7 to be positioned quickly. In addition, the groove can also help to fix the base 701 .

[0037] In some embodiments of the utility model, the large spring of the coke oven door also includes a large spring center axis 6, wherein the large spring body 5 and part of the large spring center axis 6 are arranged in a cavity, the large spring body 5 is sleeved on the outside of the large spring center axis 6, a protrusion 601 is provided on the side of the large spring, one end of the large spring body 5 abuts against one side of the protrusion 601, and the other end of the large spring body 5 abuts against the inner wall of the large spring box 8, a fifth through hole 401 is provided on the large spring pressure cover 4, the protrusion 601 abuts against the inner side of the large spring pressure cover 4, and one end of the large spring center axis 6 extends out from the fifth through hole 401.

[0038] In some embodiments of the present invention, the jack 7 is a hydraulic jack.

[0039] Generally speaking, when inspecting the large spring, the top part of the large spring center axis 6 is very easy to fly out due to uneven force on its top, such as Figure 1 The side view of the coke oven door is shown. During the coke oven production process, the large spring body 5 in the large spring box 8 is in a compressed state. The large spring body 5 abuts against the protrusion 601 of the large spring center axis 6. Under the action of the large spring body 5, the other side of the large spring center axis 6 abuts against the inner side of the large spring pressure cover 4. The large spring body 5 in the coke oven door of the utility model is used to ensure that part of the large spring center axis 6 extends out from the large spring pressure cover 4. The extended part of the large spring center axis 6 will be connected to other structures of the coke oven (omitted in the figure of the utility model). During the maintenance process, the maintenance of the large spring center axis 6 is usually involved. During maintenance, it is necessary to first remove the other structures of the coke oven, and then remove the large spring pressure cover 4, so as to take out the large spring center axis 6. However, if the large spring pressure cover 4 is directly removed, the force of the large spring center axis 6 abutting against the inner side of the large spring pressure cover 4 will disappear, and the force of the large spring body 5 abutting against the protrusion 601 of the large spring center axis 6 will cause the large spring center axis 6 to be subjected to unbalanced force and pop out, posing a threat to the safety of maintenance personnel. Therefore, the utility model solves this problem by providing a jack 7 after removing other structures of the coking oven connected to the large spring center axis 6 and before completely removing the large spring pressure cover 4. The function of the jack 7 of the utility model is to ensure that the top rod 702 of the jack 7 can also press down the large spring center axis 6 when the large spring pressure cover 4 is removed during maintenance (such as Figure 1 As shown, the top rod 702 of the jack 7 is against one end of the large spring center axis 6), so that the large spring center axis 6 is slowly unloaded under the action of the top rod 702 of the jack 7, ensuring safety when disassembling the large spring.

[0040] In some embodiments of the present invention, the second through hole 10 is disposed at a diagonal position of the top plate 2 .

[0041] In some embodiments of the present invention, the large spring cover 4 is detachably connected to the large spring box 8 by bolts.

At this time, the fixing nut 301 only plays a role in preliminarily fixing the top plate 2. At this time, the fixing nut 301 is not tightened. At the same time, the spare cap is installed on the inner side of the top plate. At this time, the spare cap 3 and the fixing nut 301 are not tightened) to preliminarily fix the position of the top plate 2;

[0046] Step 3: Determine the approximate position of the jack 7 between the top plate 2 and the large spring center axis 6 according to the height of the jack 7, align the top rod 702 of the jack 7 with the large spring center axis 6, adjust the position of the jack 7, the jack 7 has a base 701, and the base 701 has a plurality of evenly distributed third through holes, and record and mark the positions of the third through holes (in some embodiments, the top plate is provided with a groove adapted to the base, align the base 701 with the groove, and determine the position of the jack 7);

[0047] Step 4: If there is no position on the top plate 2 for installing the jack 7, in the third step, after recording and marking the position of the third through hole, use a suitable tool (such as an electric drill) to drill a fourth through hole on the top plate 2 that fits the third through hole, and then use the first bolt 11 to connect the base 701 of the jack 7 to the top plate 2 through the fourth through hole, and install the jack 7 and the top plate 2 together;
