Abstract

PURPOSE: To ensure hermetic seal of a cover by disposing two housings, respectively, on the lower (upper) wall surface of a container and above (below) the upper side face of container and providing each housing with an upper side face having downward gradient. CONSTITUTION: When the upper side face 1 of a container is enclosed, a member 11 is actuated to turn a roller 10 on rails 8, 9 thus shifting a cover 3 downward (from left to right in the drawing). Studs 16, 17 are inserted into housing 13, 14 in the vicinity of an end point and, at the same time, the roller 10 arrives at the down slope part 19 of rails 8, 9 and the upper side face of studs 16, 17 begins to touch the upper side face of housings 13, 14. Upper side face of the stud 16, 17 has down slope corresponding to the inclination angle of the upper side face of the housings 13, 14. Finally, a load and the stud 16, 17 are subjected to the pressure from concrete to the upper surface of opening and the roller 10 is removed from the rail 8, 9. A seal 2 surrounding the upper side face 1 sustains airtightness with respect to the cover 3.

The concrete container has elements which cooperate with the elements on the cover to ensure that the cover is precisely positioned; these elements essentially consist of a housing; these housings are an extension of the concrete wall. Department (
This extension is located on the one hand above the plane of the opening of the container) and in the direction of movement of the cover in which the container is to be sealed. On the other hand, if it is located well, it is placed on the concrete wall soil below the surface of the opening of the container; Figure 1
2 housings (1m and 2 housings (14m)
)It is shown. In addition to the dimensions and location of these housings, which correspond to the studs supported on the cover,
An essential feature is that the top surface slopes downward from top to bottom, so that downward pressure is applied to the cover when it is in the closed position.

The cover therefore has studs cooperating with the housing, two lower studs fil and 2 shown in FIG.
These upper studs (1η are shown) have substantially frusto-conical upper surfaces that slope downward from upper to lower, the angle of inclination being equal to the angle of inclination of the upper surface of the housing. The studs correspond to each other, while the studs have a substantially flat underside.Furthermore, these studs have a movable head that moves along the axis of the stud and a spring (11 surrounds this axis). The compression and relaxation of this spring allows axial movement of the stud.

The function of the device of the present invention is as follows; when placing a cover to seal a container, the member (summer) is activated and a roller is rotated on a rail to move the cover from top to bottom (Fig. 1) from left to right). Near the end of the travel stroke, the studs (11, +1η) are successively inserted into the housing (1 m, (141), and at the same time the rollers As the upper surface of the stud begins to contact the upper surface of the housing, the cover continues the rest of its stroke, and its load and pressure from the concrete on the stud is applied to the upper surface of the opening. At that moment the rollers (11) are disengaged from the rail and are no longer in contact with the rail. For the cover to come down in this way at the end of its stroke, some clearance is provided for the screws so that the assembly can It is necessary to allow for downward movement.
