Description

DEVICE FOR REGULATION AT HEIGHT OF A DOWNLOADER OF

CISTERNAS

DESCRIPTION

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to a device for the height adjustment of a tank discharger which has the purpose of blocking and improving the height regulation of a drive means of the tank unloader.

BACKGROUND OF THE INVENTION Currently, one of the most important actions in the installation of an unloader in a tank is its height adjustment to adapt it to the size of said tank and that the amplitude of the drive is correct for its operation.

In this sense, the invention patent with publication number ES 2258900 is known, which consists of a system for blocking the regulation elements of a tank that is intended to prevent the involuntary rotation of height adjustment elements mounted inside the interior of the cistern, so that the regulating elements are associated with guide nuts, where the coupling between them and surfaces in which said nuts stop, said coupling includes male portions and female portions that prevent involuntary rotation and unscrewing.

DESCRIPTION OF THE INVENTION

The device for height adjustment in a tank unloader that constitutes the object of the invention, comprises an elongated piece embedded within a centered recess that crosses an upper base of a main body of the unloader, where the position of said elongated part is adjustable in its axial direction and where the elongated part is associated with a part of a push-button mechanism, which when activated, moves down the main body of the unloader through the elongated part. The centered recess of the main body of the arrester comprises a through duct delimited by two facing extensions that start from the upper base of the main body, said through passage also crossing the upper base of the main body.

The two facing extensions are embedded within a circular through hole formed in a clamping piece coupled around said facing extensions forming a neck structure; where outer faces of the facing extensions are in contact with the contour of the through hole of the clamp that has rotating mobility around the facing extensions.

The two facing extensions have opposing internal portions that are facing opposite portions of the elongated piece; where in a locked position of the elongated piece, the clamping piece deforms the facing extensions causing axial retention of the elongated piece by means of the internal portions in opposition to the two facing extensions, and in a releasing position the piece of tightening does not deform the facing extensions having the elongated piece axial mobility. Upper edges of the facing extensions have internal wings facing opposite portions of the elongated piece, and other external wings; where the clamping piece is axially retained between the upper base of the main body and the outer wings of the two facing extensions. The clamping piece incorporates two opposite projections that protrude above an upper face of said clamping piece and which are at the height of the outer wings of the facing extensions; where in the locked position of the elongated piece said projections press against the outer wings by means of the two opposite projections protruding above the upper face of the clamping piece; and where in the position of release of the elongated piece the opposite projections are not in contact with said external wings of the facing extensions.

Opposite projections of the facing extensions are adjacent to the through hole of the clamp; where internal areas of the projections are a continuation of the annular surface that delimits the through hole of the clamping piece. The elongated piece comprises a rod formed by two transverse striates and two longitudinal fins arranged in a perpendicular plane with respect to the plane where the transverse striates are located that are facing the internal portions in opposition to the two opposite facing extensions of the main body of the unloader .

The longitudinal fins fit into opposing grooves as means of guiding the axial displacement of the elongated piece when placing it at the required height.

Said opposing grooves are delimited between pairs of opposite edges of the opposite extensions and between other pairs of opposite edges that delimit open recesses of the upper base of the main body; where said open recesses communicate with the interior space of the through hole located in said upper base.

The rod of the elongated piece comprises two pairs of collateral grooves between which initial sections of the longitudinal fins are located. A lower face of the clamping piece includes two opposing ribs that are complemented by two pairs of opposing projections that start from the upper base of the main body; where when the clamping piece is located in an anchoring position in which the clamping piece deforms the facing extensions causing the axial retention of the elongated piece, the two opposing ribs engage by elastic jump in individual channels delimited by those pairs of projections blocking the rotation of the clamping piece.

The through hole of the clamping piece is reinforced by two corresponding annular ribs with the opposite upper and lower faces of said clamping piece. In turn, the opposite projections protrude above the annular rib disposed on the upper face of the clamp.

Thus, in one embodiment the device of the invention is applicable to arresters where the linkage between the arrester and the push-button mechanism is a set of facing discs that must be regulated at the correct height: a disk that is part of the Push mechanism and the end disk that is part of the elongated part, all according to the height of the cistern, so that once the regulation is made, they must be perfectly fixed to avoid losing said regulation due to continued use.

The main body has been provided with an elastic coupling mechanism formed by the two facing extensions that delimit the through conduit through which the rod of the elongated piece that also integrates the end drive disk on which the disk of the disk falls Push mechanism when operated.

The way of locking the elongated part at the required height is achieved by means of the clamping piece, so that once the elongated part has been placed axially in the proper position, the clamping piece is rotated a quarter turn past a unlocking or inactive position to a locking or anchoring position in which the opposite projections of said clamping piece are pressing against the outer wings of the two facing extensions and the inner wings of said facing extensions are pressing against the transverse striations of the long piece.

To adjust the height of the elongated part, first of all, once the unloader and the push-button mechanism are installed in their respective locations, the tank cover is placed so that they contact the button of the push-button mechanism and the end disk of the elongated part, so that its rod slides axially to the operating stop of the unloading system, and then actuates the push mechanism so that the discs are positioned at the correct operating height.

In the next phase it is already possible to rotate the clamping piece to lock the elongated piece in its correct location.

With this simple operation the arrester has been perfectly regulated with total precision and its drive elements have been correctly locked to avoid mismatches due to use.

It should be noted that although the push-button mechanism and the elongated part come into contact with each other by their respective discs, it is also possible that they come into contact with each other by means of elements other than the discs. Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been represented by way of illustration and not limitation.

DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION Considering the numbering adopted in the figures, the device for the height adjustment of a tank unloader comprises an elongated piece (1) adjustable in height that is embedded within a through conduit (2) delimited by two facing extensions (3) that make up a wrap-around neck structure and which start from an upper base (4a) of a main body (4) that is part of a tank unloader (5) (6), also crossing said through conduit (2) the upper base (4a) of the main body (4).

The two facing extensions (3) of the neck are separated by two opposing grooves, where said facing extensions (3) have upper edges where internal wings (3a) and external wings (3b) are formed, below which It engages around the two facing extensions (3) of the neck a clamping piece (8) having a through hole (9) where precisely outer faces of the two facing extensions (3) of the neck are adjusted. Said opposing grooves also pass through the upper base (4a) of the main body (4) of the unloader (5), two open recesses (7) forming on said upper base (4a). which are part of the aforementioned opposing grooves.

Said clamping piece (8) is axially retained between the upper base (4a) of the main body (4) and the outer wings (3b) of the two facing extensions (3). On the other hand, the internal wings (3a) of said facing extensions (3) are in contact with the elongated part (1).

Said elongated part (1) can be fixedly anchored in different positions to place an upper end of the elongated part (1) that is faced with a lower end of a push mechanism (19) coupled to a cover (6a) of the cistern (6), so that by pressing on said push button mechanism (19) the main body (4) of the unloader (5) is moved downwards by means of the elongated part (1), thus causing the tank to be emptied (6) ) through its exit drill. The elongated part (1) comprises a rod (1 a) and an end disk (1 b) on which a part of the push-button mechanism contacts when it is pressed to activate the unloader (5) and empty the tank (6) . The rod (1 a) of the elongated piece (1) has two transverse striations (10) and two longitudinal fins (1 1) arranged in a plane perpendicular to the plane where the transverse striates (10) are located, so that the Longitudinal fins (1 1) fit into the opposing grooves to guide the movement of the elongated piece (1) when placing it at the required height. The rod (1 a) of the elongated piece (1) comprises two pairs of collateral grooves (12) between which initial sections of the longitudinal fins (1 1) are located.

The transverse striations (10) of the elongated piece (1) are faced with the internal wings (3a) of the two facing extensions (3), so that the clamping piece (8) is in an anchor position, some edges sharp internal wings (3a) of the opposite extensions (3) press against the two transverse striations (10) of the elongated piece (1). In this anchoring position, the clamping piece (8) presses against the outer wings (3b) of the facing extensions (3) by means of two opposite projections (13) protruding above an upper face of the clamping piece (8) and which are adjacent to the through hole (9) of said clamping piece (8). In contrast, a lower face of the clamping piece (8) opposite the upper face includes two opposing ribs (14) that are complemented by two pairs of opposing projections (15) that start from the upper base (4a) of the main body (4), so that when the clamping piece (8) is located in the anchoring position, the two ribs (14) fit by elastic jump in two channels (16) delimited by those protruding pairs (15 ), thus securing said anchor position.

To lock and unlock the anchoring position of the elongated part (1) it is necessary to rotate the clamping piece (8) with an effort in which it is elastically deformed by contacting the ribs (14) with the projections (15) of the upper base (4a) of the main part (4) of the arrester (5). During this operation the two facing extensions (3) in solidarity with the main body (4) of the unloader (5) are also elastically deformed inwards. On the other hand, to move from an inactive position to an active position in which the elongated part (1) is locked in the axial direction, the clamping piece (8) is rotated until the opposite projections (13) of the workpiece clamp (8) contact radially against the two outer wings (3b) of the facing extensions (3) and the ribs (14) of the clamp (8) fit into the channels (15) delimited by the pairs of projections ( 15) of the main body (4) of the arrester (5).

When the clamping piece (8) is in an inactive position, its opposite projections (13) are not in contact with the outer wings (3b) of the two facing extensions (3) in solidarity with the main body (4) of the arrester (5) ) and therefore the elongated part (1) can be moved in an axial direction to place it at the required height, since in said inactive position, the two internal wings (3a) are not pressing against the two transverse striations (10) of the elongated piece (1).

On the other hand, the through hole (9) of the clamping piece (8) is reinforced by two annular ribs (17), (18) corresponding to the upper and lower faces of said clamping piece (8), respectively; where opposite projections (13) protrude above the annular rib (17) disposed on the upper face of the clamping piece (8). In one embodiment, the device of the invention is applicable to arresters (5) where The link between the unloader (5) and the push mechanism (19) is a set of facing discs that must be adjusted to the correct height: a disk (19a) that is part of the push mechanism (19) and the end disk (1 b) that is part of the elongated part (1), all according to the height of the tank (6), so that once the regulation is made, they must be perfectly fixed to avoid losing said regulation due to use continued.
