Definitions

  • Closing device for loading or unloading openings in transport tanks in particular for rail-bound tank and bulk goods wagons
  • the invention relates to a closure device for loading or unloading openings in transport tanks, in particular for rail-bound tank and bulk goods wagons, according to the preamble of claim 1.
  • lids which are to be designed according to the requirements for different pressure loads.
  • the operating personnel must generally remove the Press the bulk wagon to operate the container locks. Climbing onto the transport containers and actuating the locking devices is associated with a considerable risk to personnel, because with transport containers the work platform can often not be provided with a railing in view of a fully used standard light room.
  • the closure devices also come into contact with adverse weather conditions such as rain, snow, slippery surfaces and the like. Like., To be operated outside protected shelters.
  • opening and closing the locking devices manually directly on the locks can be dangerous or even hazardous to health due to the nature of the cargo.
  • US-A-2,669,250 therefore suggests filling and emptying transport tanks from below and ensuring necessary pressure equalization from below via remote-controlled ventilation on the lids.
  • the aforementioned arrangement cannot be used as intended for loading from above, for example in the case of bulk goods.
  • a closure device for the lid for remote-controlled opening and closing of the lid is missing, which in particular enables and ensures a required opening angle.
  • the US-C-4,327,522 shows a generic closure device which has a remotely controllable adjusting means and a pivotable cover which is actuated and secured by means of articulated linkage, with a control lever of the linkage which can be acted upon by the adjusting means via parts of the linkage on the one hand diametrically to the pivot bearing of the cover for generation and the pivoting movement is articulated on the lid and is also articulated on parts of the linkage on a locking hook and unlocks the locking hook before pivoting on the closed lid and locked after the lid has been pivoted closed. Parts of the linkage protrude considerably in the closed position.
  • the locking hook is unlocked via a linkage chain with an adjusting means, a lower and a lever arm and an actuating arm for opening against the force of a spring arranged between the lower and upper parts of the lever arm and against the force of an elastic bending element arranged between the cover and the actuating arm.
  • the same actuating arm causes the cover to swing open when the adjusting means acts against the force of the spring.
  • the adjusting means releases the lower lever arm, whereupon the relaxing spring pivots the lever arms, the actuating arm and the cover hinged to it via a locking lever.
  • Such a closure device the linkage parts of which The lid and the boiler shell protrude significantly, is uneconomical and unsuitable for transport boilers, since the maximum height of the loading space and thus the volume of the transport boiler must be reduced if the standard light room is specified and complied with.
  • the linkage parts for the pivoting movement of the cover for the actuation of the locking hook are connected in a row arrangement or are largely identical, reliable functioning of the locking device requires a precise adjustment of the linkage parts and an exact adjustment and compliance with the spring characteristics of the spring and the bending element.
  • the linkage for the actuation of the locking hook in the closed position is not in an appropriate top dead center position against forces acting on the locking hook, caused, for example, by a cover subjected to internal pressure, but is only held and secured by spring forces.
  • DE-Al-35 03 544 shows a closure device which meets the requirements for a flat design.
  • a pivotable cover In the closed position, a pivotable cover is pressed onto its seat via a linkage which is supported on the one hand on the boiler jacket and on the other hand engages the cover, whereby a Angle lever is supported on the boiler casing and can be operated by remote control by the working lever acting on the short lever arm, the long lever arm, which is connected to another rod part, which acts on the cover and secures it by a dead center position of the rod.
  • the rod parts in the closed position extend approximately parallel and at a short distance from the boiler shell.
  • This locking device is only intended for unpressurized or lightly loaded loads and cannot ensure the required tightness of the locking device in the case of pressurized loads, in particular in the event of pressure unloading of bulk goods wagons, since the rod parts act too resilient in the closed position and there is only two-point support for the lid. A locking hook and linkage for remote-controlled operation is not provided.
  • the invention is therefore based on the object of designing a generic closure device in such a way that, in the case of a flat design in the closed position, the tightness in the specified pressure range is ensured even with pressurized loads, in particular when pressure is being discharged from bulk goods wagons, and pivoting of the cover by remote-controlled actuating means when the opening angle is required remains feasible.
  • the closure device according to the invention essentially has a cover 1, a linkage 2 which pivots and secures the cover 1 and a remote-controlled actuating means 3.
  • the closure device according to the invention additionally has a crossbar 4 connecting the linkage 2 and actuated by this adjusting means 3.
  • the crossmember is arranged in the closed position on the top of the boiler 5 in the transverse axis of the closure device above the cover 1 on the side of the pivot axis 6 of the cover 1.
  • the linkage 2 arranged on the crossbeam 4 at both ends is advantageously mirror-symmetrical to the longitudinal axis of the vehicle or to the longitudinal axis of the locking device.
  • a pivot bearing 7 is arranged parallel to the pivot axis 6, about which a lever triangle 8, pivoted approximately in the region of the knee, can be pivoted.
  • the lever triangle 8 is supported in a bearing block 9 and the associated bearing 10 on the boiler side, while the opposite corner of the lever triangle 8 guides a control lever 11 by means of a bolt 12 arranged thereon in an elongated hole 13 that extends from this end of the lever triangle 8 extends towards the bearing 10.
  • the control lever 11 is supported at one end by means of a bearing 14 in the bearing block on the boiler side.
  • a control lever rod 16 is attached via a joint 15, which is connected to the control lever rod 16 of the mirror-symmetrical linkage 2 and extends beyond the cover 1 in the direction of the longitudinal axis of the closure device.
  • a pull-push rod 18 engages in the joint 17, which actuates a locking hook 19 via a joint 20, which positively locks the cover.
  • the locking hook 19 is supported on the boiler side via a joint 21 and bearing block 22.
  • the control lever rod 16 is provided on the part projecting above the cover with a guide 23, for example with an elongated hole arrangement, into which the cover 1 engages by means of a guide element 24. In the closed position, the bolt 12 is arranged below the pivot bearing 7.
  • the actuating means 3 is actuated, whereupon the cross member 4 acts on the linkage 2 arranged on both sides.
  • Each linkage is 2 operated simultaneously and with the same effect.
  • the crossbar 4 engages via the pivot bearing 7 on the lever triangle 8 and rotates it in the bearing 10 in the direction of rotation of the following lid pivoting movement.
  • the lever triangle 8 guides the control lever 11 by means of bolts 12 and slot 13 during the forced rotation about its boiler-side support in the bearing 14.
  • the control lever rod 16 is raised in its articulation point in the joint 15 on the control lever 11 and at the same time pivoted in the direction of rotation of the lever triangle 8 .
  • control lever rod 16 moves upward and the cover-side guide element 24 into the inner end position of the articulation (guide element 24 / guide 23) of the control lever rod 16 on the cover 1 which is displaceable longitudinally in the direction of the control lever rod 16.
  • the control lever 11 engages when it rotates about its pivot point in bearing 14 at its other end in the joint 15 on the cover 1 and rotates it beyond its approximately vertical center of gravity position.
  • the cover 1 falls due to the force of gravity acting on it with its guide element 24 in the direction of the outer stop 23a in the guide 23.
  • the time at which this stop 23a is reached by the guide element 24 depends on the angular velocity of the control lever 11 following this cover pivoting in the joint 15, ie at the articulation point of control lever 11 and control lever rod 16, since with the variation in the angular velocity of the joint 15 the position of the stop 23a in relation to the position of the guide element 24 of the cover 1 is definable.
  • the cover movement is intercepted or damped via the control lever rod 16 or ultimately by the actuating means 3, for example a working cylinder.
  • the guide element 24 of the cover 1 bears against the inner stop 23b of the guide 23.
  • the bolt 12 arranged on the control lever 11 pivots about the bearing 14.
  • One end of the pull and push rod 18 acts on the joint 17.
  • the other end of the pull and push rod 18 pivots the locking hook 19 in the locked position and engages over the cover 1 in a form-fitting manner.
  • the actuating means 3 acts on the linkage 2 until the linkage 2, with its control lever 11 and its pull and push rod 18, assumes an over-center position with respect to the joint 17.
  • the joint 17 is arranged in the locked position below the connecting straight line through the bearing 14 and the joint 20.
  • the locking hook 19 is locked against pivoting until the joint 17 is arranged above the connecting straight line through the bearing 14 and the joint 20.
  • Forces on the locking hook 19, caused by the cover 1 pressurized with internal pressure can, as is known, by expediently self-locking arrangement and design of the contact surfaces between the locking hook 19 and cover 1, ie by creating an over-center position of the locking hook 19 in the sense of a reinforcement of the clamping forces can also be used.
  • the point of application of the locking hook 19 on the cover 1 is adjustable in height, whereby the contact pressure of the cover 1 on the dome neck 26 is adjustable.
  • the actuating means 3 pivots the control lever 11 in the direction of rotation of the cover 1 via the lever triangle 8.
  • the joint 17 arranged on the control lever 11 is pivoted out of its over-center position, the pull and push rod 18 arranged on the joint 17 closing the locking hook 19 unlocked and the lid 1 releases.
  • This unlocking process is always completed before the cover 1 is lifted. Therefore, during the unlocking process of the locking hook 19, the guide element 24 slides in the guide 23 from the inner stop 23b to the outer stop 23a.
  • a further pivoting of the control lever 11 pivots the cover 1 beyond its equilibrium position via the outer stop 23a. The cover 1 falls into its end position “opened” by gravity
  • the time interval between the unlocking process and the application of the cover 1 can instead of with the guide element 24 and the guide 23, d. H. by moving a bolt in an elongated hole, also by means of an articulated scissors arranged at the end of the control lever rod 16, which is only brought into the locked position after the complete release of the locking hook 19 and lifts the cover 1.
  • Locking device can be configured, in which the actuating means 3 acts directly on the control lever 11 while leaving the lever triangle 8 which enables variable lever ratios.
  • actuating means 3 acts directly on the control lever 11 while leaving the lever triangle 8 which enables variable lever ratios.
  • a considerably longer adjustment path of the adjusting means 3 is to be realized or a different gear is to be provided.
  • the cover 1 can still be operated by manually moving the control lever 11.
  • the joint 17 is to be levered out of its over-center position using simple tools, for example a rod.
  • the closing movement of the cover 1 and the placing of the locking hooks 19 in the locked position is carried out by manually pivoting the cover 1 and pivoting the control lever 11.
