Lashing device for containers

Description

The invention relates to a device for lashing containers on ship decks or the like with a tension member (lashing rod), the upper end of which with a container and. the lower end of which is connected to a deck anchorage by means of a tensioning element.

The effective anchoring of containers, which are usually arranged in layers on top of each other, on the deck of a ship requires the use of special anchoring devices. These usually include cleaning devices using lashing rods or ropes, which are connected with

saw on the one hand on the ship deck and on the other hand anchored in corner fittings of the containers.

OMPI ' An example of such a lashing device is described in DE-A-30 09 257. The lashing rod connected to the container by means of a hook-in fitting can be connected to a tensioning element, which in turn is connected to the deck-side latch. The tensioning element comprises a spindle drive through which the required tension can be introduced into the lashing system. A hook-shaped coupling piece (coupling hook) connected to this serves to connect the lashing rod to the tensioning element.

The hook-shaped design of the coupling member requires that the connection system contain a movement in such a way that the counterpart to be inserted into the hook-shaped coupling member (anchoring thickening) reaches the required seat. This requires a .relative movement between the organs to be connected to each other (dead stroke). This in turn requires additional work, which is undesirable in the special conditions of ship operation.

The invention is based on the object of further developing and improving the locking system according to DE-A-30 09 257. In particular, the handling is to be facilitated and simplified, especially when establishing the connection between the bar and the tensioning element. Furthermore, the invention aims to simplify the construction of the lashing system in such a way that the manufacturing and processing costs are reduced.

To achieve this object, the device according to the invention is characterized in that the connection

sπ the lashing rod with the tensioning element is secured by an adjustable bolt.

The invention is based on the _finding, based on that a substantial improvement can be achieved in the handling of the tie-down, when the required when connecting and lashing rod clamping member Todhub wi avoided d. This is possible according to the invention in that the organs to be connected to one another are brought into engagement only by means of a relative transverse connection without a lifting movement and are then secured in the coupling position by a separate locking.

According to a further proposal of the invention, the bolt is connected to the tensioning element and is designed as a locking ring with a passage gap. The latter corresponds in 3er Montagest.el 1ung with a recess in the tensioning element, namely in a counter bearing thereof, such that the lashing rod can be moved into the coupling position by relative transverse movement (transverse axial movement). This position is secured by turning the locking ring.

The tensioning element is designed in a special way according to the invention, namely it consists of an anchoring piece for receiving the anchoring end of the lashing rod and a tensioning element which preferably comprises a spindle drive. Anchoring piece and clamping piece are made of a common workpiece.

According to another proposal of the invention, there is an intermediate between the lashing rod and the tensioning element. piece releasably attached, using a connection corresponding to the connection between the lashing rod and tensioning element designed in the sense of the invention. The intermediate piece enables the use of lashing rods of uniform length and design as well as the adaptation to different dimensions on site by switching on an intermediate piece, by means of which the effective length of the lashing rod can be adjusted.

A particularly simple and inexpensive manufacture is also taken into account in the constructive configuration of the lashing device. In this sense, the organs required for generating the tensile stress, namely the spindle and the spindle nut, consist of cast workpieces which are used without machining. For this reason, the spindle and spindle nut are equipped according to the invention with (cast) round threads. In a preferred embodiment, a first spindle designed in this sense is attached to the tensioning member, while a second, likewise cast, spindle with a round thread is to be connected to the front end. The two spindles formed with opposite threads are connected to one another by a common sleeve, which is also cast and has a round thread that matches the spindles. Such a tensioning element can be produced particularly inexpensively and is nevertheless easy and reliable to use.

For anchoring containers 20 on a ship deck 21 or the like. serve lashing devices which are anchored on the one hand in an (upper) corner fitting 22 of the container 20 and on the other hand on a forward eye 23 attached to the ship deck 21. The lashing device consists of two parts which can be coupled together, namely a lashing rod 24 and a tensioning element 25. Instead of the lashing rod 24, a lashing rope or another suitable traction means can also be used.

The free end of the lashing rod 24 enters with a hooking fitting 26 into the corner fitting 22 of the container 20, which is designed in a known manner, while the lower end of the tensioning element 25 is detachably coupled to a tiltable bracket 28 of the latch 23 via a plug pin 27. The preparation device designed in this way extends in the diagonal direction with respect to the end face of the container 20.

The parts of the preparation device, namely the lashing rod 24 on the one hand and the tensioning element 25 on the other hand, are first connected individually to the container (corner fitting 22) or to the front end 24. The lashing rod 24 is in this assembly in the vertical position according to the dash-dotted line 29. The tensioning member 25 is on the ship deck 21 assembled horizontally. The two parts are then pivoted into the diagonal position 1 and connected to one another. The procedure is such that first the tensioning member 25 along the part 1 circular arch 30 into the di agonal position and then the lashing rod 24 along the part 1 circular arch 31 are also pivoted into the diagonal position. Due to the configuration of the lashing rod 24 and tensioning element 25, the connection position is achieved without axial movement, that is to say exclusively through the transverse axial movement thereof.

The lashing rod 24 is preferably formed with a plurality of coupling points in the lower coupling area. namely anchoring thickenings 32. A plurality of them are arranged at a distance from one another on the lashing rod 24 in order to ensure different lengths of the lashing device. One of the anchoring thickenings 32 is brought into engagement with the tensioning element 25 in such a way that tensile loads can be transmitted.

The tensioning element 25 consists of an anchoring piece 33 and a tensioning piece 34. The former serves to accommodate the anchoring thickenings of the lashing rod 24 by engaging one of the anchoring thickenings 32 each with a counter bearing 35 Clamping the device. For this purpose, the clamping piece 34 is equipped with a spindle 36 and a spindle nut 37.

The counter bearing 35 arranged at the (upper) end of the anchoring piece 33 consists of a head-like thickening of the anchoring piece 33 Anchoring thickening 32 is in contact with a transversely directed, essentially flat bearing surface 38 of the counter-bearing 35. An axial through opening 39 is formed in this, which corresponds approximately to the transverse dimensions of that of the lashing rod 24, so that this in the assembled position can pass through the passage opening 39. The arrangement is such that, in this assembled position, the lashing rod 24 and tensioning member 25 are oriented coaxially (see, for example, FIG. 3).

The lashing rod 24 ^* formed in the region of the bearing surface 38 facing side of the anchor thickening 32 with a likewise transversely axially directed, planar support surface wesent¬ union 40th Due to the undercut-free design of both the bearing surface 38 and the support surface 40, it is possible to bring them into engagement with one another by exclusive transverse axial relative movement of the lashing rod 24 and the tensioning element 25. An axially directed insertion movement is not necessary for this. The counter bearing 35 is provided with a lateral recess 41 to carry out the required relati movements (see in particular FIGS. 7 and 8). In order to secure the lashing rod 24 in the assembled position against unintentional sliding out through the recess 41, a releasable locking is provided.

In the exemplary embodiments shown, this consists of a locking ring 42 which is arranged on the tensioning element 25, namely in the region of the counter-bearing 35. By turning the locking ring 42 in the circumferential direction, the locking position becomes

f O manufactured or solved. For this purpose, the locking ring is also provided with a cutout 43 which, when covered with the lateral recess 41 of the counter-bearing 35, enables the lashing rod 23 to be introduced into the coupling position or in the opposite direction of movement to disengage. In the locking position, the locking ring 42 is rotated so that the cutout 43 has no overlap with the recess 41. The Verriege¬

10 lungsring 42, ie a partial ring, covers the recess (see for example Fig. 3). The locking ring 42 is sliding in an annular groove 44 of the

) Counter bearing 35 stored and guided.

Due to the loads and the resulting friction, no special securing of the locking ring 42 against unintentional rotation is required. According to the exemplary embodiment in FIG. 5, however, a securing bolt 45 can pass through

20 bores 46 of the counter-bearing 35 are passed through, specifically in the area of the cutout 43 of the locking ring 42. The securing bolt 45 is provided with a spring clip 47 which causes it to engage.

25

The anchoring piece 33 and a directly adjoining part of the clamping piece 34 preferably consist of a common workpiece. 2 and 3 there is anchoring

30 approximately piece 33 from a tube section 48, which is provided on one side with a full length or height continuous opening 49. This allows the insertion of a protruding part of the lashing rod 24 into the area of the clamping piece 34.

35 Accordingly, this has a part-circular cross-section here.

^* TO

OMPI 1 in the Ausführungsbe game of FIGS. 2 and 3 is followed by a closed pipe section 50, which forms the spindle nut 37 at the lower end. In this embodiment, the entire clamping

5 organ 25 - with the exception of the spindle 36 - rotated about its own longitudinal axis in order to introduce the required tension into the lashing system. For this purpose, a handwheel 51 is attached to the tensioning element 25 in the area of the counter bearing 35. The rotary movement of the tensioning element 25 takes place relative to the lashing rod 25 which, in the exemplary embodiment mentioned, is designed with a circular cross section and has cylindrical anchoring thickenings 32.

15

4 shows another possible construction of the lashing rod 24 and tensioning element 25. The former here consists of flat material or of a workpiece with a rectangular or square cross section. At this

20 there are anchoring thickenings 32, which likewise have a rectangular cross section and only extend on two opposite sides of the lashing rod 23, while the anchoring thickenings 32 extend in the region of 90 °

25 set level have the same dimension as the lashing rod 24 (see in particular Fig. 8). The lashing rod 24 designed in this way cannot be inserted into the tensioning organ 25 at every relative position, that is to say tilted, but rather in a predetermined manner

30 relative arrangement. In the exemplary embodiment shown, it is provided that the support surfaces 40 of the anchoring thickenings, which extend on both sides of the lashing rod 24, on the one hand on the bearing surface 38 of the counter-bearing 35 and on the other hand on the

35 locking ring located in the locking position

OMPI 42 are present (Fig. 6). The (lower) boundary surfaces 52 of the anchoring fittings 32, which lie away from the support surfaces 40, are formed obliquely. As a result, this boundary surface 52 corresponds to a likewise obliquely directed guide surface 53 on the opposite side of the counter bearing 35 to the bearing surface 38. The mutually adapted design of the boundary surface 52 and guide surface 53 facilitates the threading of the lashing rod 24 into the coupling position.

In this embodiment (FIG. 4), a part of the anchoring piece 33 facing the counter bearing 35 is fork-shaped by means of two tension struts 54 arranged at a distance from one another. The projecting end of the lashing rod 24 is accommodated between them. The tension struts 54 converge in a (lower) connecting piece 55. A spindle 56 is attached, in particular forged, to this in one piece (common workpiece). A tubular sleeve 57 as part of the clamping piece 34 is provided at both ends with a spindle nut 58 and 37. The upper spindle nut 58 is in engagement with the spindle 56 and the lower spindle nut 37 is in engagement with the spindle 36. In this exemplary embodiment, the tensile force is generated by rotating the sleeve 57 with a handwheel 51. For this purpose, the spindles 36 and 56 are formed with opposite threads, as are the associated spindle nuts 37 and 58.

The couplings between parts of a lashing system described so far enable the use of an intermediate piece 59 which changes the effective length (FIGS. 9 to 11). In this embodiment it is assumed that lashing rods 24 of uniform length are used, regardless of the

O PI given dimensions. In the case of larger dimensions, the intermediate piece 59 is connected as an extension of the lashing rod 24.

The intermediate piece consists of two differently designed coupling parts for connection to the lashing rod 24 on the one hand and to the tensioning element 25 on the other. For the connection to the lashing rod 24, a special coupling piece 60 is intended, to which a lashing rod piece 61 connects with anchoring thickenings 32 in the sense of the previously described exemplary embodiments.

The coupling piece 60 here consists of two side walls 62 and 63 connected by transverse connections. Between these, counterbearing pieces 64 and 65 extend as bearings for the anchoring thickenings 32 of the lashing rod 24. In the exemplary embodiment shown, the counterbearing pieces 64, 65 are located opposite one another Sides arranged with respect to the lashing rod 24, so that two anchoring thickenings 32 are grasped and held on opposite sides. This results in a tilt-proof, offset-free support and mounting of the lashing rod 24. The free, projecting end of the same extends in the area between the side walls 62, 63. The lashing rod 24 is introduced into this coupling position in the axial direction or with a slightly angled position between lashing rod 24 and coupling piece 60. An insertion opening 66 is formed between the counter bearing pieces 64 and 65, which has sufficient dimensions. On the side opposite this insertion opening 66, the coupling piece 60 must be open so that an approximately protruding end of the

OMPI Lashing rod 34 can protrude from the area of the coupling piece 60 during the coupling process.

As can be seen from FIG. 11, this solution also applies to lashing rods with a square or rectangular cross section. A special feature of this embodiment example is that an anchoring end 67 of the lashing rod with the anchoring thickenings 32 consists of flat material, while

10 the remaining, subsequent part of the same is designed as a round material.

FIG. 12 shows a variant of the exemplary embodiment in FIG. 1. Because here is one

15 lashing rod 24 provided with coupling eyes 68 and connected to the tensioning element 25 via a separate connecting piece 69. The connecting piece 69 is provided with reinforcement thickenings 32 in the manner described. The connection with the coupling

20 pulley eye 68 can be made via a shackle connection 70.

A special feature that can be used for all of the exemplary embodiments described is described in FIG. 13.

25 In its basic structure, this corresponds essentially to the embodiment according to FIG. 4. The sleeve 57 here, like the spindle 36 and the spindle 56, consists of a cast material (cast steel). The external thread 0 71, 72 arranged on the spindles 36, 56, as well as the corresponding internal thread 73, 74 of the sleeve 57, consist of round threads which are cast directly with the sleeve 57 or the spindles 36, 56. A special, additional (machining) machining of these parts is not required here. This version is therefore special
