Abstract

A double-lidded lock for closing two openings of any cross-section which may be joined to each other, for example for coupling toxic material containers to the bottom opening of a containment, has a lid (3) for closing the bottom opening (1) which may be lifted by a device and which forms the top lid of a double-lidded closing system with one or several swivelling hoops (8) that can swivel around an axis (4). The closing lid (3) is hinged by its side opposite to the opening to the swivelling hoops (8) so as to swivel or tilt around another axis bolt (11) parallel to the swivelling axis bolt (4).

Description

Two of lockings can interconnect the double-canopy gate of perforate

The present invention relates to a kind of double-canopy gate, be used to seal two perforates that can interconnect of arbitrary section shape, preferentially be used for being communicated with the pest container in the coupling of the bottom opening place of storing apparatus, double-canopy gate has the bottom opening closing cap that can open by means of certain device, as the top cover of double-canopy system.

In the conventional construction of this double-canopy gate, need guide cylinder in order to open closing cap, purpose is before closing cap is opened by the revoliving arm upset along circular trace, can be rotated away from its seal vertically from base plate.Mainly revolving shaft for the space former thereby be provided with when the closing cap, on the one hand in order to prevent that closing cap from tilting in flange, on the other hand at first in order to prevent that owing to side friction destroys sealing, this moving process is necessary.

Therefore, the objective of the invention is to, introduce a kind of new double-canopy flashboard, concerning it, closing cap can be in simpler mode, for cited reason, vertically, with respect to encapsulant, rise or roll back again on its bearing from its bearing.

For solving this purpose, the present invention has recommended the feature quoted in the characteristic of claim 1.Other suitable feature of the present invention is open in the characteristic indication of claim in the back.

Advantage of the present invention is at first that except that accurately vertically opening the lid because revolving shaft is directly adjacent to the installation possibility of perforate, the size of double-canopy gate may be significantly reduced, and perforate can have for example rectangle or foursquare arbitrary section form.

Explain other details of the present invention in detail below and by means of accompanying drawing 1 to 3.Among the figure,

Fig. 1 has showed a planimetric map that has the double-canopy flashboard of dome as embodiment, wherein also may be rectangle certainly, the perforate and the lid of square or other polygonal shape.

Fig. 2 showed along the cross section of AA among Fig. 1,

Fig. 3 has showed the view of B direction in Fig. 1.

Double-canopy flashboard is used to be enclosed in one without the charging door 1 in the base flange 6 of the base plate 2 of the container of expression in detail, is to belong to the work box of handling environmentally hazardous material at special cases lower shoe 2, and sealing is to carry out by means of the double-canopy technology of what is called.Comprise that base flange 6 and the charging hole 1 that covers can be circular in this case, the rectangle square waits other shape yet for example also can have.

In double-canopy technology, in the process of being of coupled connections, wait to be connected to each other for two, two of the container of external seal are covered under the situation sealed to each other of their outside be clamped together.Container is connected to each other in this process.Two cover after clipping together, and are fed in the middle of two contaminated containers in inside, perhaps rotate inwardly from perforate with a kind of device, such two lids that are clamped together facing to inside surface remain not contaminated.The disconnected from each other of lid correspondingly is reversed.In other words, after disconnected from each other, unpolluted cap surface is positioned at the outer survey of container now again.For present this double-canopy flashboard, only consider to be attached in the double-canopy flashboard container, a turning lid of opening.

On the substrate 2 that is showed in the drawings, be called a lid of this double-canopy system of container closure 3 here, above base flange 6 by means of the revolving shaft 4 that is positioned at bearing seat, can be used as whole towards gyratory directions 7 from perforate in 1 upset open or roll back in the hole.In this case, revolving shaft 4 should as close as possible perforate 1 for the reason of saving the space.Be positioned at a side on revolving shaft 4 opposites in double-canopy system, a clamp device 19 that has handle 20 is fixed on the flange 6, by means of it, be positioned on the beam 15, the closing cap that is in closed state is pressed in its seal and is fixed, except this fastening and latching-type covered of clamp device, also might use other type locking device that has electronic, hydraulic pressure or pneumatic actuating device by means of the band handle.

Use special mode to finish closing cap 3 fixing on revolving shaft 4 now:

Having welded two with being separated by and rotated clips 8 on revolving shaft 4, closing cap 3 with rotate on the clip hanging over relative to deflection way, and they pass through the connection of yoke 15 mutual connections.For this reason, on the survey face 12, two other bearing spider 9 is installed at the back of the body of closing cap 3 in the perforate 1, they have along the fulcrum post 10 of the continuous rotation of axle 11, rotate clip 8 and are fixed on again on the fulcrum post 10.So closing cap 3 can also be around axle 11 deflections and rotation except that wraparound rotating shaft 4 revolutions.Axle 11 is positioned at the last survey face 12 of closing cap 3 here or carries on the back on the side of perforate 1 as having carried.

At the downside that rotates clip 8, between revolving shaft 4 and axle 11, be screwed into one or several distance screws 13, their adjustable top 14 has restricted closing cap 3 with respect to rotating moving of clip 8.One or several solid pin 16 of the regional internal fixation of the downside of this external rotation clip 8, crossbeam 15, it is outstanding with the direction towards lid 3, and a longer spring that exceeds the pin length range is arranged on them.Lid 3 has one section cavity 18 on the opposite of this root spring 17, spring is projected in the cavity when being close to when covering 3 flange 6.

The working method of double-canopy flashboard is as described below:

Closing cap 3 is by means of rotating capstan or certain other device that is not showed on the clip 8, overturns along circular arc line around axle 4.Can relatively rotate clip around axle 11 rotations because cover 3, thereby its position so lid moves a segment distance behind the top 14 of touching distance screws 13, just is removed with rotation clip 8 with respect to rotating the clip change.It is upwards overturn and keeps this upset up to arriving the last upturned position that is not showed in this state.When descending in the opposite direction, lid 3 was swung before the perforate 1 that is put back into horizontal level soon, and at this moment gap 17 interior springs 18 play a role, and was in covering in the seal from this moment beginning to be pressed onto.Cover 3 if open again now, before it opens as mentioned above so, during vertically opening, remain in the short time in the rebound path of spring 17.
