Abstract
The utility model relates to a manhole device of a container. The manhole device comprises a manhole ring, a manhole cover plate and a manhole screw rod, wherein the manhole screw rod is vertically fixed on the center of the outer surface of the manhole cover plate by welding; a cross sleeve, a presser and a pressing nut are arranged on the manhole screw rod from the inside to the outside in sequence in a through manner; the presser is pressed by the pressing nut; the cross sleeve comprises a primary sleeve and a secondary sleeve, wherein the primary sleeve is mutually vertical to the secondary sleeve; two supporting bases are fixed on the manhole ring by welding; a supporting shaft is sleeved in the holes of the two supporting bases; the supporting shaft is welded with an overhanging arm; the other end of the overhanging arm extends to the secondary sleeve; the end part of the overhanging arm is provided with an annular groove; and an anti-skidding bolt gets through the secondary sleeve and is embedded to the annular groove. The manhole device of the container provided by the utility model has a reasonable structure design, can be conveniently and flexibly dismounted and mounted, and can reduce labor intensity, improve working efficiency and reduce a danger coefficient.
Description
Technical field
The utility model belongs to Vessel Design and makes field, specifically a kind of container people aperture apparatus.
Background technique
Bear on the tankage of interior pressure, in order to satisfy the equipment needs that personnel enter internal tank inspection, repair, clean when out of service, when manufacturing and designing this type of pressure vessel and equipment, usually need to arrange at the cylindrical shell of container the manhole device of some.When needs enter internal tank inspection, repair, when cleaning, take the cylindrical shell outside by manually the manhole device being disassembled from cylinder inboard wall, to be checked, repair, clean finish after, need again by manually the manhole device is installed onto the inner barrel of container from the cylindrical shell outside.Because this type of manhole device must adopt interior closed type structure, and the area of plane of cover plate for manhole is greater than the area of manhole ring, cause cover plate for manhole inside and outside container, directly to pass in and out, must carry out dismounting, carrying by the method for artificial rotation, cause labor intensity larger; And, in disassembly process, exist the manhole device to drop and cause the injured danger of operator.
The model utility content
For the problems referred to above, the utility model provides a kind of container people aperture apparatus of structure uniqueness, and this container people aperture apparatus is reasonable in design, can be very convenient, dismantle deftly, install, can reduce labor intensity, and increase work efficiency, reduce risk factor.
The utility model is achieved through the following technical solutions: a kind of container people aperture apparatus, comprise manhole ring, cover plate for manhole, the manhole screw rod, described manhole screw rod is weldingly fixed on the center of cover plate for manhole outside, run through successively from inside to outside on the described manhole screw rod and overlapping cross sleeve, press horse, gland nut, described cross sleeve, press horse to compress by gland nut, described cross sleeve comprises master collet and time sleeve, described master collet is mutually vertical with time sleeve, 2 supporting bases have been welded and fixed on the described manhole ring, be set with back shaft in the middle of the hole of described 2 supporting bases, described back shaft and cantilevered leg welding, the other end of described cantilevered leg extend in the inferior sleeve of cross sleeve.
As improvement, the end that described cantilevered leg stretches into time sleeve is provided with an annular groove, and Antisliding bolt passes time sleeve and embeds in the described annular groove.
After the utility model has been taked above-mentioned corrective measure, its effect of optimization is remarkable: because the axis of the axis of the axis of cantilevered leg back shaft, cross sleeve master collet, cross sleeve time sleeve is on 3 mutually perpendicular plane of rotation, the institute so that cover plate for manhole can in 3 mutually perpendicular planes, freely rotate as required, thereby when the dismounting manhole device, cover plate for manhole can freely rotate as required, frees in and out inside and outside container; Thereby realize conveniently dismantling deftly, install the manhole device, reach reduction labor intensity, increase work efficiency, reduce the purpose of risk factor.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 1 side view;
Fig. 3 is the partial enlarged drawing of A section among the utility model embodiment 1.
1 is cover plate for manhole among the figure, the 2nd, and the manhole screw rod, the 3rd, press horse, the 4th, cross sleeve, the 5th, Antisliding bolt, the 6th, gland nut, the 7th, cantilevered leg, the 8th, back shaft, the 9th, supporting base, the 10th, manhole ring.
Embodiment
The below's contrast accompanying drawing is further described the utility model in conjunction with the embodiments:
With reference to Fig. 1, Fig. 2, shown in Figure 3, a kind of container people aperture apparatus among the embodiment 1, comprise manhole ring 10, cover plate for manhole 1, manhole screw rod 2, cross sleeve 4, press horse 3, gland nut 6, manhole screw rod 2 vertical weldings are fixed on the center of cover plate for manhole 1 outside, cross sleeve 4, press horse 3, gland nut 6 to run through successively from inside to outside to be enclosed within on the manhole screw rod 2, cross sleeve 4, press horse 3 to compress by gland nut 6.Cross sleeve 4 comprises master collet and time sleeve, master collet is mutually vertical with time sleeve, 2 supporting bases 9 have been welded and fixed on the manhole ring 10, be set with back shaft 8 in the middle of the hole of 2 supporting bases 9, back shaft 8 and cantilevered leg 7 welding, the other end of cantilevered leg 7 stretches in the inferior sleeve of cross sleeve 4, and its end is provided with an annular groove, Antisliding bolt 5 passes and is embedded into the groove of cantilevered leg 7 ends from inferior sleeve, prevents that this manhole device is from cantilevered leg 7 slippages.
During the tankage maintenance, the step of dismounting cover plate for manhole is as follows:
1, unclamp gland nut to the certain position of manhole screw rod, pressing horse to turn over 90 ° of angles, then the end from the manhole screw rod is advanced to whole manhole device in the container;
2, the master collet clockwise direction half-twist of cover plate for manhole along cross sleeve, the inferior sleeve along cross sleeve is rotated counterclockwise 90 ° again, and the position of cover plate for manhole just becomes minor axis the horizontally suspend state parallel with the major axis of manhole ring;
3, pull out cantilevered leg, whole cover plate for manhole just can take out in container easily.
Overhaul completely, according to the above-mentioned steps contrary operation, just can put into container to cover plate for manhole from outside of containers easily.
What more than enumerate only is specific embodiment of the utility model, and obviously, the utility model is not limited to above embodiment.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should belong to protection domain of the present utility model.
