Abstract
ABSTRACT
A mobile steeping tank (1) in the form of a closed container has at least one top loading hatch (2) attached to a framework (3) which is supported so as to be able to pivot on the steeping tank (1) on hinges (4) and with a pivoting system that is supported on a side wall (5) of the steeping tank (1), and which acts on the loading hatch (2) to open and hold it in the open position, and with a closer to hold the loading hatch (2) tightly in the closed position. The pivoting system and the actuation of the closer are physically combined in a lifting device which in the closed position of the loading hatch (2) has an idle phase in respect to the closing movement of the loading hatch. In this idle phase a locking mechanism is actuated by the lifting device (6), acting in each instance on at least two locking cams (7, 7a) that are each arranged on each long side of the steeping tank (1) and with which the loading hatch (2) can be brought into close contact on the corresponding contact sur-faces in the top of the steeping tank (1).

Description
2 ~
The present invention relates to a mobile steeping tank in the form of a closed container having at least one loading hatch in its top.
Such a steeping tank is descrlbed in Applicant's pre-viously unpublished DE-P 40 05 535.3. There, the loading hatch that is arranged in the top of the steeping tank is suspended on a framework through hinges. In its turn, the framework is supported, so as to be able to pivot outward, on three hinges, in the area of one upper long edge of the steeping tank. In order that the loading hatch can be opened ana kept open, the framework is extended outwards, from the middle of the three hinges in the form of a two-arm lever. A lifting de~ice (that is preferably configured as a threaded spindle) can engage on this lever arm that extends outwards and this then brings about an appropriate pivoting movement of the framework and the loadirlg hatch that is suspended therefrom hy a shortening o its axial length. When the hatch is closed, the axial length of the lif~ing device is altered in the reverse manner. This solution is simple from the construction standpoint and ensures that the loading hatch i5 kept safely open when in the open position.
In order to ensure that the loading hatch remains tight-ly closed and hermeticall~ sealed when in the close~ position, i.e., during the steeping process, this steeping tank incorporates a special tensioning system that works as follows. The framework that contains the loading hatch is extended outwards beyond the side wall of the steeping tank on the side that is opposite the hinges and i5 provided with a closer. ~he thrust block of a second threaded spindle that is supported on the outside of the steeping tank can be swung into this closer, so that a positive connection is formed between the threaded spindle and the frame-work. By shortening the effective length of the threaded spindle as a result of appropriate rotation, the closer and thus the whole of the framework can be forced downwards. As a consequence, the loading hatch is pressed onto the contact surfaces that are provided in the top of the steeping tank (which are fitted with ~lexible seals) through the hinge connections with the framework.
In order to generate as even an application pressure as possible, the hinge connections are spaced equally along the longitudinal axis of the loading hatch between the framework and the loading hatch.
This design ensures reliable seating, although it also requires a relatively massive, i.e., sti~, con~iguration of the loading hatch because the application pressure is introduced into the loading hatch from the centre. However, this can be improved from the standpoint o~ the low~st possible weight o~ the steeping tank and lower production costs. In addition, it is a disadvan-tage that the lifting device is separated by function and location from the closing device, with the result that corre-spondingly more time is required to operate both systems. In addition, there is also the fact that projecting components are arranged not only on one but on two side walls of the steeping tank.
Thus, it is the aim of the present invenkion to so improve a steeping tank as described in DE-P 40 05 535.3 that the above disadvantages are largely eliminated.
The invention provides a mobile steeping tank comprising a closed container with at least one loading hatch in the top of the steeping tank; the loading hatch being attached to a frame-work, which is supported so as to be able to pi~ot on the steeping tank on hinges and With a pivoting system that is supported on the outside of one side wall of the steeping tank, and which acts on the loading hatch to open said loading hatch and hold it in the open position; and a closer to hold the loading hatch tightly in the closed position, characterized in that the pivoting system and the actuation of the closer are physically combined in a lifting device; in that the lifting device has in. the vicinity of the closed position of the loading hatch an idle phase in respect to the closing movement o~ the loading hatch; and in that in this idle phase a locking mechani~m can he actuated by the lifting device, said locking mechanism acting on at 1east two locking cams arranged on each long side o~ the steeping tank and with which the loading hatch can be brought into close contact with the corresponding contact surfaces at the top of the steep-ing tank.
The operation of the steeping tank has been made much simpler and the time required for op~ration has been greatly reduced by the physical combination of the functions "opening the loading hatch and keeping it open," and "sealing and locking 2 ~
the loadin~ hatch" into a single operating system, The inte-gration of the two unctions has been made possible in that an idle or neutral phase has been incorporated in the operation of the lifting device ln the vicinity of the closed position of the loading hatch, because of which at times the actuation system lS available solely for operating the locklng mechanism of the loading hatch. In a similar way, actuation during the outward pivoting of the loading hatch is not functionalIy'connected with the locking mechanlsm.
The in~ention will be described in greater detail on the basis of the figures l to 4 appended hereto:, wherein:-Figure 1 is a plan vlew (A) of a~steeping tank according to the present invention;
Figure 2 is the side ~iew (C) corresponding to figure l;
Figure 3 is a cross-section taken on the line B-B in 'figure 2; and Figure 4 is a cross-section taken on the line D-D in figure 3.
Figure 1 shows a plan view o~ the top of a mobile steep-ing tank 1 according to the present invention. The rectangular loading hatch 2, which could also be divided into a number of smaller individual hatches, is joined by t'hree hinges 19 ko a framework 3. This framework'3, which can be formed, for example, from box-cross section tubular profiles, is secured in its turn to the outside of the roof surface of the steeping tank 1 through three hinges 4 in the area of an upper longitudinal edge of the steeping tank 1. Within the area of the middle axis o the load-ing hatch 2 there is a longitudinal beam of the framework 3 ana this extends outwards beyond the ~ace side 5 of the s~eeping kank 1. A lifting device 6 that is used to raise the loading hatch 2 acts on the end of the longitudinal beam.
The lifting device 6, which is more clearly seen from the drawing at figure 2~ incorporates an actuatiny crank 9 and a connecting element 8 that is connected to one end of this through the hlnged joint 17. The other end of the coupling element 8 is connected to the end piece of the longitudinal beam of framework 3 through a connecting rod 10. The manner in which the connec-tion to the longitudinal beam is arranged can be s~en in the sectional drawing at figure 3. A connectin~ rod 10 that is con-figured as a double-arm lever is supported in a fork at the end of the longitudinal beam so as to be able to rotate. The pivot shaft 11 of this articulated joint lies parallel to the framework 3.
The connecting element 8 of the lifting device 6 engages on the first lever arm 10a o the connecting rod 10 that exkends outwards.
To this end, it is not directly connected; rather, an indirect coupling is shown, this being ef~ected by means of a cardan joint v 12, the pivot shafts of which are numbered 12a and 12b.
The second lever arm of the coupling element 10 is formed as a stop cam 10b. When the connecting rod 8 of the lifting device 6 is raised, the coupling element 10 first rotates only about the shaft 11, without the framework 3 moving. Only ~hen a minimum rota~ional an~le (up to this point, for technical reasons, there 7~ 9J~
is an idle or neutral phase) has been reached, and which is indicated b~7 the dashed butline of the coupling element 10, does the stop cam 10b come to rest on a corresponding stop surface on the framework 3, so that only then is ~here a positive actuating connection between the lifting device 6 and the framework 3. On further operation of the lifting device 6/ the framework 3 and, of necessity, the loading hatch 2, are pivotea outwards about the hinges 4 into the open position.
In its idle or neutral phase, the coupling element 10 activates a locking mechanism for the loading hatch 12. To this end, its first lever arm 10a has, on its underside, an operating cam 13 which, when the loading hatch 2 is in its lo~er position, engages in an operating rod 14 and which comes out o engagement when the loading hatch 2 is opening. In order to ensure problem-free engagement o the operating cam 13, the operating rod 14 incorporates slide-type guides that grow wiaer in a conical shape towards the top and the operating cams 13 are provided wlth rounded sliding surfaces.
The method of operation of the locking mechanism can be seen in figures 1 and 4. Rotatable locking cams 7, 7a are evenly spaced on both long sides of the loading hatch 2, on the outside of the top surface of the steeping tank 1. When rotated through a relatively small angle ~e.g., 40 to 45), these locking cams 7, 7a slide into engagement with corresponding lugs on the loading hatch 2.
~93 ~
The sliding surfaces o~ the locking cam 7, 7a and/or the retaining lugs are so inclined that with increasing rotation there is a small downward movement of khe loading hatch 2 in order to generate application ~orce and to achieve a tight seal on the contact surfaces of the loading hatch 2. More expediently, the contact surfaces are provided on one side with a flexible seal. The rotation of the locking cam 7, 7a during the locking and unlocking of the loading hatch 2 is effected in each instance by means of a locking rod 15 that is arranged on each long side. In each instance, the locking rod 15 is hinged so as to be able to rotate on one side of the locking cam 7, 7a which, in the present example, are each configured as a double-armed lever. One end of each locking rod 15 is connected through a push rod 16 to the operating linkage 14. Each of the attachmen~s for the push rod 16 is in the form o~ a pivoting joint ~hinge).
The operating linkage 14 is supported in horizontal slide-type guides and in the range of the "idle phasel' o~ the connecting rod 10, when this is rotated abou~ the shaft 11, it i~ is ~lid in the horizontal direction by the operaking cams 13. Because of the tra~smission of force through the push rod ~6 and the locking rods 15 this leads to a rotation of all the locking cams 7/ 7a and accordingly (depending on the direction of displacement) to the loading hatch 2 being either locked or unlocked.
In the example shown, the push rod 16 is articulated at a differ~nt point on the locking cam 7a than is the case with the 3~
locking rod 15 because this permits a greater angle of rotation of the locking cam 7, 7a for the same amount of travel by the operating linkage 14.
In figure 2, from the kinematic standpoint, the frame-work 3 with the actuating crank 9 and the connecting rod 8 as well as the side wall 5 form a four-joint chain in the form of a crank and rocker linkage. The side wall 5 is a fixed member, 9 is the actuating crank (that can be rotated), 8 is the connec-ting rod, and 3 is the member of th~ four-joint chain that moves back and forth.
A further modification of the present invention is that in place of the actuating crank 9 and the connecting rod 8, there is provided only a variable length drive member (which is rigid) in the form of a threaded spindle, or of a hy~raulic or pneumatic cylinder/plunger system. ~Iowe~er, this would result in the disadvantage of longer paths of movement for the drive element between the open and the closed po~ition O.e the loading hatch 2. In contrast to this, a four-joint chain as in figure 2 incorporates a gearing-up, by means of which the relatively large pivoting movement of the loading hatch is initiated by comparatively short paths of movement ~or the drive elements.
In addition to the fact that the mechanism that is used to lock and unlock and to raise and lower the loading hatch is extremely q 3. ~
simple and quick to operate (operation from one single point), the present invention also entails the advantage of ea~ier construction of the loading hatch since, because of the fact that the loading hatch does not have to be particularly stiff and resistant to twisting because the force needed to push it into the locked position is applied from th~ edge~ of the hatch.
The present invention relates to a mobile steeping tank in the form of a closed container having at least one loading hatch in its top.
Such a steeping tank is descrlbed in Applicant's pre-viously unpublished DE-P 40 05 535.3. There, the loading hatch that is arranged in the top of the steeping tank is suspended on a framework through hinges. In its turn, the framework is supported, so as to be able to pivot outward, on three hinges, in the area of one upper long edge of the steeping tank. In order that the loading hatch can be opened ana kept open, the framework is extended outwards, from the middle of the three hinges in the form of a two-arm lever. A lifting de~ice (that is preferably configured as a threaded spindle) can engage on this lever arm that extends outwards and this then brings about an appropriate pivoting movement of the framework and the loadirlg hatch that is suspended therefrom hy a shortening o its axial length.

Because of the tra~smission of force through the push rod ~6 and the locking rods 15 this leads to a rotation of all the locking cams 7/ 7a and accordingly (depending on the direction of displacement) to the loading hatch 2 being either locked or unlocked.
In the example shown, the push rod 16 is articulated at a differ~nt point on the locking cam 7a than is the case with the 3~
locking rod 15 because this permits a greater angle of rotation of the locking cam 7, 7a for the same amount of travel by the operating linkage 14.
In figure 2, from the kinematic standpoint, the frame-work 3 with the actuating crank 9 and the connecting rod 8 as well as the side wall 5 form a four-joint chain in the form of a crank and rocker linkage. The side wall 5 is a fixed member, 9 is the actuating crank (that can be rotated), 8 is the connec-ting rod, and 3 is the member of th~ four-joint chain that moves back and forth.
A further modification of the present invention is that in place of the actuating crank 9 and the connecting rod 8, there is provided only a variable length drive member (which is rigid) in the form of a threaded spindle, or of a hy~raulic or pneumatic cylinder/plunger system. ~Iowe~er, this would result in the disadvantage of longer paths of movement for the drive element between the open and the closed po~ition O.e the loading hatch 2. In contrast to this, a four-joint chain as in figure 2 incorporates a gearing-up, by means of which the relatively large pivoting movement of the loading hatch is initiated by comparatively short paths of movement ~or the drive elements.
In addition to the fact that the mechanism that is used to lock and unlock and to raise and lower the loading hatch is extremely q 3. ~
simple and quick to operate (operation from one single point), the present invention also entails the advantage of ea~ier construction of the loading hatch since, because of the fact that the loading hatch does not have to be particularly stiff and resistant to twisting because the force needed to push it into the locked position is applied from th~ edge~ of the hatch.
Claims (9)
1. A mobile steeping tank comprising a closed container with at least one loading hatch in the top of the steeping tank, the loading hatch being attached to a framework, which is supported so as to be able to pivot on the steeping tank on hinges and with a pivoting system that is supported on the out-side of one side wall of the steeping tank, and which acts on the loading hatch to open said loading hatch and hold it in the open position; and a closer to hold the loading hatch tightly in the closed position, characterized in that the pivoting system and the actuation of the closer are physically combined in a lifting device; in that the lifting device has in the vicinity of the closed position of the loading hatch an idle phase in respect to the closing movement of the loading hatch; and in that in this idle phase a locking mechanism can be actuated by the lifting device, said. locking mechanism acting on at least two locking cams arranged on each long side of the steeping tank and with which the loading hatch can be brought into close contact with the corresponding contact surfaces at the top of the steeping tank.
2. A steeping tank as defined in claim 17 characterized in that the lifting device is formed with a lifting linkage that acts on the framework of the loading hatch through a connecting rod; in that the connecting rod is in the form of a two-arm lever that is supported on the framework so as to be rotatable about a shaft that is parallel to the plane of the framework;
in that the first lever arm of the connecting rod is connected to the lifting linkage so as to be free of bending forces, and in that the second lever arm of the connecting rod is configured as a stop cam; in that the first lever arm incorporates an operating cam that, when the loading hatch is in the closed or almost closed position, engages as a positive fit in an operating linkage of the locking mechanism that is supported so as to be moveable on the steeping tank; and in that the operating linkage is functionally connected to two locking rods that are each supported on the long side on the top of the steeping tank, with which the locking cams that are associated with it, and of which there are at least two, can be operated.
in that the first lever arm of the connecting rod is connected to the lifting linkage so as to be free of bending forces, and in that the second lever arm of the connecting rod is configured as a stop cam; in that the first lever arm incorporates an operating cam that, when the loading hatch is in the closed or almost closed position, engages as a positive fit in an operating linkage of the locking mechanism that is supported so as to be moveable on the steeping tank; and in that the operating linkage is functionally connected to two locking rods that are each supported on the long side on the top of the steeping tank, with which the locking cams that are associated with it, and of which there are at least two, can be operated.
3. A steeping tank as defined in claim 1, characterized in that the elevating linkage is in the form of a spindle drive that can be operated either manually or by a motor.
4. A steeping tank as defined in claim 2, characterized in that the elevating linkage is in the form of a hydraulic or pneumatic plunger/cylinder system.
5. A steeping tank as defined in claim 2, characterized in that the lifting linkage viewed in the cross section of the steeping tank, with the framework and the side wall on which the lifting linkage is supported, forms a four-joint chain in the form of a crank and rocker linkage, from the kinematic standpoint, in which connection the side wall forms the fixed member and the framework forms the crank element that moves back and forth.
6. A steeping tank as defined in claim 5, characterized in that the smallest element of the crank and rocker linkage is configured as an actuating crank.
7. A steeping tank as defined in claim 6, characterized in that the actuating crank can be rotated by means of a spindle drive that is articulated onto it and which can be operated either manually or by a motor.
8. A steeping tank as defined in claim 6, characterized in that the actuating crank can be rotated by means of an articulated hydraulic or pneumatic plunger/cylinder system.
9. A steeping tank as defined in claim 7 or claim 8, characterized in that the hinging is arranged in the area of the hinged joint of the actuating crank and the connecting rod of the crank and rocker linkage.
