Description

The utility model relates to the field of mechanical engineering, namely to means for closing and opening massive covers and similar elements with vessel bodies for various purposes, in particular special purpose cameras, designed to ensure safety during isolation, transportation and liquidation of explosive devices.

Known shutter device of the camera hatch, described in the invention under the name "Camera" [a.s. USSR No. 1048209, F16J 13/22, publ. 10/15/1983 g]. This device includes a flange-mounted lid mounted on the camera hatch, and is associated with a lid removal and movement device located outside the camera. The cover removal device is made in the form of a beam mounted on a movable frame with guides, pivotally connected by means of a rocker arm to the cover rods.

This chamber refers to the construction of large-sized vacuum chambers with loading from above. To open the cover, the pumping station mounted on the frame, on command from the control station, supplies the working fluid to the hydraulic cylinders, whose plungers move the beam in the vertical plane. Traction rods move the camera cover up. The raised cover slides in the horizontal plane until the camera hatch is completely released.

However, cameras with a cover removal mechanism of a known design are characterized by the presence of a powerful and metal-intensive drive mechanism, an increase in the metal consumption of the camera body due to the mounting of the removal mechanism on the latter, the complexity of the cover removal mechanism and the inability to use such a design for cameras installed in cramped overall working conditions and away from communications.

Known bolt device cylindrical capacity [and.with. USSR No. 1656109, E05F 15/00, B65D 90/66, publ. 06/15/1991 g]. This device includes a flange-mounted lid mounted on the camera hatch, and is associated with a lid removal and movement device located outside the camera.

The device for removing and moving the lid contains a guide, curved with vertical sections at the ends, for moving the lid, rigidly fixed to the upper outer surface of the container along its generatrix, and a mechanism for opening and closing the lid, consisting of two chain gears placed in a vertical plane symmetrically from two side sides of the tank, and self-braking drive with a horizontal shaft.

To open the lid, a self-braking drive is activated, which drives both chain gears. The lid moves upward with simultaneous rotation from a vertical plane to a horizontal one taking into account the arched profile of the guide.

This device is convenient in operation in a limited area of the room, because after lifting the lid goes into position above the cylindrical container, not occupying the production area and does not complicate the passage and execution of loading work.

However, this device requires power supply. Using a drive complicates the device, the design is metal-intensive and requires considerable time for assembly and disassembly. In addition, control during operation is required: failure of the chain drive will not allow opening the tank, which reduces reliability when using the shutter device in special cameras (SPW).

Known shutter of the camera hatch [RF patent No. 2492381, B65D 90/10, F16J 13/00, publ. September 10, 2013 g], comprising a lid mounted on a camera hatch with a flange connected to a lid removal and moving device located outside the camera.

The cover removal device is made in the form of a movable hinge mounted for movement along the axis of the camera and attached by fasteners with a hinged part to the outer surface of the cover, and a supporting part to the camera. In the hinged part of the hinge, a through longitudinal guide groove is made, in which the hinge pin is mounted, coaxially threaded through holes for clamp-and-release bolts are made at both ends of the groove. Additionally, the removal device is equipped with a locking bolt mounted across the groove with a distance from the edge by the value of the diameter of the finger.

To open the shutter, the locking bolt is unscrewed, the clamp-wring bolts are screwed in as far as they will go. In this case, the hinged part of the hinge, rigidly connected with the cover, makes the cover move progressively along the axis of the chamber until it completely leaves the hatch. After that, the locking bolt is screwed back, which makes it possible to perform a rotational movement around the hinge pin. The lid is rotated up to 180 °, freeing the hatch for further technological operations. The known device is taken as a prototype, as the closest in technical essence to the claimed.

This device is simple and convenient to use for SPEs installed in cramped overall working conditions and away from communications.

However, a disadvantage of the known device is that when the shutter is opened, the lid on the rotary device is folded 180 ° to the side, while the lid may sag under its own weight due to the presence of gaps in the structure due to manufacturing tolerances. And therefore, it is necessary to center the lid when closing the shutter to avoid skewing and ensure tightness, which is especially important for SPEs in conditions of uneven ground (for example, mine workings). In addition, with the lid open to the side, inconvenience to service, difficulty in the passage of diagnostic tools and other working tools necessary for work with SPEs, which may adversely affect the safety of work with explosive devices, arise.

The technical result, the achievement of which the proposed utility model is aimed, is to improve operational characteristics by providing centering of the lid relative to the plane of the hatch in the face of uneven ground and increasing ease of use while ensuring the safety of special-purpose cameras located away from communications in cramped overall working conditions and not requiring the use of special lifting equipment.

To achieve the specified technical result in the shutter device of the camera hatch, including a lid mounted on the camera hatch with a flange, connected to the device for removing and moving the lid placed on the outside of the camera, according to the proposed utility model, the device for removing and moving the lid is made in the form of a cart consisting of at least two wheelsets, the axle boxes of which are rigidly connected with height-adjustable jacks that support the frame - a platform with support legs installed on it, a lodgement and a fixing element the volume, made in the form of a tender, adjustable in length, attached at one end to the frame, and the other at the bottom of the cover with the possibility of detachment, while each of the support posts, placed symmetrically on both sides of the central axis of the cover, is equipped in the upper part mounted rotatably on axis supporting locking element attached to the flange of the cover detachable connection.

The implementation of the device for removing and moving the lid in the form of a trolley, consisting of at least two wheelsets, the axle boxes are rigidly connected with height-adjustable jacks that support the frame — a platform with supporting posts installed on it, a tool tray and a fixing element made in the form adjustable along the length of the tender, one end attached to the frame and the other to the bottom of the cover, with each of the support posts placed symmetrically on both sides of the central axis of the cover, equipped with a mounted turn in the upper part reliably on the axis with a supporting fixing element, it is possible, on the one hand, to securely fix the lid on the trolley in order to prevent it from shifting and to avoid tipping over when lifting and adjusting the angle of inclination by means of jacks under uneven ground conditions, thereby ensuring that the lid is centered relative to the plane of the camera hatch located far from communications in cramped overall working conditions and not requiring the use of special lifting equipment, and on the other hand makes it possible to remove, take away on a trolley eplennuyu cover of the hatch area at a certain distance, providing easy access to the open manhole chamber, which increases the ease of use, while ensuring the safety of works on iOS.

Installing a tender with the possibility of detaching from the bottom of the lid, as well as attaching supporting fixing elements to the flange of the lid with a detachable connection, makes it possible to remove the trolley after docking the lid with the neck of the body for further use of the SPL (testing using explosive loading or further transportation of the chamber), which increases the convenience during operation and makes it possible to reuse the device.

In addition, the use of a locking element in the form of a tender, which makes it possible to quickly approach or extend the joined parts, adjust their axial position relative to each other, and also equip the support racks with support fixing elements rotatable on the axis for interaction with the cover flange allows you to adjust the cover removal device to different overall size of the cover (diameter of the flange of the cover and the depth of its bottom) for reliable pressing of the cover to the tool tray, which positively affects how performance, and the versatility pickup device and moving the cover.

Thus, the totality of all the above signs creates the conditions for creating a shutter device located away from communications in cramped overall working conditions and not requiring the use of special lifting equipment, but allowing to improve the operational characteristics and ease of use of special purpose cameras.

The presence in the claimed utility model of features that distinguish it from the prototype, allows us to consider it appropriate to the condition of "novelty."

The utility model is illustrated by drawings:

in FIG. 1 shows a general view of a shutter device;

in FIG. 2 is a view A of FIG. one;

in FIG. 3 shows the adjustment of the position of the cover;

in FIG. 4 is a view B in FIG. 3.

The device is as follows.

The camera 1 has a hatch on which the cover 2 is hermetically mounted, having a flange 3 with holes for bolts 4 and connected to the device for removing and moving the cover placed from the outside of the camera 1 (Fig. 1). The device for removing and moving the cover is made in the form of attached to the cover 2 with the possibility of detaching the cart. The trolley consists of at least two wheelsets 5, axle boxes 6 of which are rigidly connected to four jacks 7, supporting the frame - platform 8. Two support legs 9, a tool tray 10 and a fixing element made in the form of an adjustable the length of the tender 11, one end attached to the frame 8, and the other to the bottom of the cover 2 with the possibility of detachment. Frame 8, support racks 9 and lodgement 10 are welded beam structures. To make a tight fit of the bottom of the lid 2, the lodgement 10 in shape repeats its profile. The support posts 9 are symmetrically mounted on both sides of the central axis of the cover 2 (Fig. 2), which together with the lodgement 10 creates the reliability of the support for the cover 2. Each of the support posts 9 is equipped in the upper part with a support fixing element 12 mounted on a pivot mounted on the axis and attached to flange 3 with bolts 13.

The device operates as follows.

The lid 2 is fastened with an SPL by a flange 3 with bolts 4 (in the SPL there are about 36 pcs.). The device for removing and moving the lid (trolley) is rigidly connected to the lid 2: the supporting fixing elements 12 are attached to the flange 3 of the lid 2 with two bolts 13, and the tender 11 is attached to the bottom of the lid 2.

The removal of the cover 2 (Fig. 3, 4) from the hatch of the SPL under uneven ground is carried out using four jacks 7, which raise the platform frame 8, adjusting it in height and angle. Why change the height of each of the jacks 7 individually or all together. Simultaneously with the jacks 7, with the help of the tender 11, by rotating its coupling depending on the depth of the bottom of the cover 2, the bottom of the cover 2 is securely attached to the lodgement 10 and the flange 3 of the cover 2 is in contact with the supporting fixing elements 12. Then, after dismantling all the bolts 4, the trolley attached to lid 2 roll away from the open hatch of chamber 1 to a safe distance, allowing you to safely carry out work with SPEs.

The docking of the cover 2 (Fig. 3, 4) with the neck of the chamber 1 is as follows. A trolley with an attached lid 2 is rolled up to the hatch of the chamber 1. And with the help of four jacks 7, the lid 2 is docked with the hatch of the КСН with the centering of all holes for the bolts 4 made in the flange 3 under uneven ground. To do this, depending on the position of the axis of the cover 2 and the hatch of the chamber 1 by adjusting the height, i.e. lowering (raising) the two front jacks and raising (lowering) the two rear jacks, adjust the longitudinal angle a. The transverse angle p is adjusted by lowering (raising) the two right jacks and raising (lowering) the two left jacks. After aligning all the holes for the bolts 4, screw the bolts 4 until the cap 3 is completely tightened with the hatch of the SPL. Next, two bolts 13 are unscrewed from the flange 3, disconnecting the supporting fixing elements 12, and two bolts 4 are installed in the holes that have been freed up in the flange 3. Tender 11 is also disconnected from the bottom of the cover 2. The trolley is rolled back. The chamber is ready for further testing or transportation.

At the enterprise, tests were carried out on the shutter device of the KSN hatch, the results of which confirm the convenience of maintenance in the cramped overall conditions of work without the use of special lifting equipment and the reliability of centering the lid relative to the plane of the KSN hatch under uneven ground.
