According to the rubber membrane 2 sealed gas chamber provided by the embodiment, the side plates of the chamber are segmented, and one end of the rubber membrane 2 is clamped between the two side plates, so that the gas chamber has high connection stability and working reliability and good stress performance, and the rubber membrane 2 can better bear the frequent drawing acting force of a piston; and the condition that the sealing angle steel 13 used for fixing the rubber membrane 2 is welded in the cabinet is avoided, and the risk of gas leakage caused by the corrosion of the gas in the cabinet on the sealing angle steel 13 is reduced.
Further preferably, the rubber membrane 2 is sealed at a clamping position between the two sections of side plates, so as to ensure the sealing performance and safety of the gas tank. In the above scheme that "the bottom end of the upper section side plate 11 and the top end of the lower section side plate 12 are respectively welded with the seal angle steel 13", preferably, as shown in fig. 1, a seal rubber 17 pad 14 is respectively clamped between the rubber membrane 2 and each horizontal side plate, so that the sealing performance of the clamping position of the rubber membrane 2 can be ensured, and the rubber membrane 2 can be better protected. Of course, the sealing method is not limited to the above-mentioned sealing method, and is not exemplified here.
The structure of the gas chamber is further optimized, the upper section side plate 11 and the lower section side plate 12 are preferably prefabricated into an integral structure respectively, and then are fixedly assembled, so that the manufacturing efficiency of the gas chamber can be improved, and the construction period can be shortened. The traditional side plate manufacturing mode can be adopted; in this example, the following preferred scheme is adopted:
as shown in fig. 2, the upper side plate 11 and/or the lower side plate 12 are spiral roll plate type side plates, the spiral roll plate type side plates are continuous steel strips which rise spirally, and adjacent steel strip edge portions 16 are bent and engaged to form engaging connecting ribs protruding outwards.
The spiral positioning of the continuous steel strip and the forming of the interlocking connecting ribs are mainly completed by a spiral winding machine set, the spiral winding machine set generally comprises an uncoiler, a forming machine and an interlocking machine, wherein the uncoiler is used for uncoiling and uncoiling a steel strip coil, the forming machine can process and form the steel strip, and the interlocking machine bends and interlocks two adjacent steel strip edges 16 to form the interlocking connecting ribs. The spiral rolling bin unit is mature equipment in the field of construction of the Lipu bin, and the specific structure and the working process are not described herein any more.
The side plates are manufactured by adopting continuous steel belts, the structural integrity is high, the side plates can be manufactured without complex welding work on the premise of ensuring the structural strength and the performance reliability of the side plates of the gas cabinet, time and labor are saved, the construction period of the side plates of the gas cabinet and the gas cabinet can be obviously shortened, and high-altitude operation can be avoided; because no welding seam exists, the leakage and corrosion weak points are obviously reduced, and the operation safety of the gas tank can be improved.
Because the side plates are continuous steel strips which rise spirally, the bottom end of the upper section side plate 11 and the top end of the lower section side plate 12 can be cut and leveled respectively, and then the rubber film 2 is clamped.
As shown in fig. 3 to 6, the engagement rib is formed by bending and engaging the adjacent steel strip edge portions 16, and it can be understood that, in two adjacent steel strip spiral sections, the lower edge portion of the upper steel strip spiral section is engaged with the upper edge portion of the lower steel strip spiral section; after the side plates are manufactured and molded, spiral continuous connecting rib belts can be formed on the peripheries of the side plates, and the side plates have good attractiveness.
Generally, the two steel strip side portions 16 of the interlocking connection rib are bent for a plurality of times, and even if a small gap exists between the two portions, the multi-bending interlocking structure can provide a labyrinth sealing effect and can play a role in sealing gas. In the embodiment, at least part of the occlusion connecting ribs are preferably subjected to sealing treatment, so that the sealing performance of the gas tank can be further improved, and the operation reliability and safety of the gas tank are ensured. Wherein, preferably, each occlusion connecting rib in the side plate area which is contacted with the gas at least is sealed; for the area of the side plate which does not need to be contacted with the gas, the occlusion connecting rib in the area can be not additionally provided with a sealing means.
For the sealing treatment means, the following solutions are included but not limited to:
(1) as shown in fig. 6, the sealing seam 19 is formed between the two corresponding steel strip edges 16 at least partially engaging the connecting rib, i.e. the two weldments corresponding to the sealing seam 19 are the two steel strip edges 16. Wherein the sealing weld 19 can be formed at the beginning of the snap-in connection rib, i.e. at the beginning of the bending of the two steel strip edges 16, and can be welded inside the side plate; the sealing bead 19 can also be formed outside the side panel, for example by a partial edge bend which is in contact with the side panel wall and welded thereto.
(2) As shown in fig. 4 and 5, at least a part of the snap-fit connection rib is a seal-type connection rib in which a seal rubber 17 is interposed between two steel band side portions 16. Since the two steel band edges 16 need to be engaged with each other, the sealing rubber 17 is generally ensured to perform a sealing function.
In a further preferred scheme, as shown in fig. 5, the sealing connection rib is further provided with a plurality of locking bolts 181, and each locking bolt 181 vertically penetrates through the sealing connection rib and the sealing rubber 17 and then is in threaded connection with a locking nut 182. This scheme can further guarantee above-mentioned leakproofness and connect the sealed effect of rib.
Further, the gas chamber side plate further comprises a plurality of stand columns, and based on the structure of the occlusion connecting rib, the stand columns can be welded on the occlusion connecting rib, so that the operation is convenient, and force transfer between the side plate and the stand columns is clear.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
