Norway-Norway (NO) 700925 (71) (72) Johs. 0ksland, 6910 Bremanger, Norway-Norge (NO) (7 ^) Oy Heinänen Ab (5 ^) Arrangement in the cattle barn - Anordning vid ett boskapsgaller

The present invention relates to an arrangement in a cattle grate comprising a frame with transversely spaced transverse grate sections fixed to the side edges of the frame, adjustable from a first position in which the spacing between the grate sections is relatively large (summer position) to a second position with minimal spacing (winter position) , the grate parts being pivotable between the first and second positions.

Livestock gratings have to a considerable extent replaced ordinary gates, which form an obstacle for both drivers and walkers, when their main purpose is to act as a barrier to access for domestic animals on pasture, etc. During the summer, livestock gratings form an effective barrier e.g. for animals on pasture but allow unobstructed passage of vehicles. Livestock gratings cause certain disadvantages to vehicles during the summer, as they are crossed at a reasonable speed to avoid unwanted loads on the vehicle, but even greater problems are caused by livestock gratings in winter, when road variations increase when the gratings are on the road and larger snow deposits before grating. 651 55 plows and the like can also have a lot of problems crossing the gratings without the plow damaging the grate or vice versa. Many roads with gratings have thus had to remove the gratings every autumn and fill the grating pits with filling or cover the grating with intact iron plates which are screwed into place on top of the grating. This must, of course, be done again in the spring in reverse order. In any case, this becomes a laborious and expensive operation twice a year.

DE-OS 2 321 917 discloses grating parts which consist of a pipe part and a radially outwardly directed plate part. When the plate part is turned directly from the folded down position (summer position) to the horizontal position (or fault position, 1), the plate part acts as a cover plate over the space between the two pipe parts.

The plate parts are able to support the wheels of the vehicle very little and n = bend easily downwards (deform or turn).

The object of the present invention is to avoid the disadvantages of the known solutions by means of a simple and strong structure.

The device according to the invention is characterized in that the grating parts are rotatably mounted on an upper frame which is vertically and horizontally displaceable relative to the base with respect to a fixed attachment, a lower frame and which can be tightened to two different positions (summer and winter). have slightly different heights relative to the second frame, and that the second frame is provided with vertical, spaced apart support portions for receiving the grate members in the first position (summer position) and receiving them in the second position (winter position), the grille portions in the first position being arranged in the grooves between the support members in position are arranged to be received on their respective platforms at the tips of the support members. In the cattle grid according to the invention, both grate parts consist of a sufficiently rigid and strong tubular material and can each individually effectively support the vehicle wheels in the upright position. In both positions (winter and summer positions), in addition, effective support and stiffening of the loaded pipe-grating part is achieved by means of two longitudinally connected grating parts. Such longitudinal interconnection can effectively counteract the bending of a single 65155 3-grid pipe section when loaded with a vehicle wheel. The solution according to the invention also allows the other side of the grate parts to wear or deform, whereby by turning the grate parts 180 ° in the upper frame, the opposite side of the grate parts can be utilized.

Karjaritilän itself being changed position to the summer-winter position can be avoided except where necessary to täytemassoi1, used and removed again every six months, and instead make a change in an easy way a simple, portable tools.

In view of plowing trucks and similar snow clearing means, it is advantageous that the gratings can be adjusted to different heights, i.e. to a normal height position at road level during the winter season when the cattle grid is closed. When changing to the open position during the summer season, it will be about 10-15 cm higher, thus preventing any bumps that might otherwise occur if the grating parts were at road level.

In this case, it is possible · with different and special shapes of the grille parts to turn the grate parts to different height levels at the same time when the gratings are turned to their two different positions by a relatively large distance (summer position) or a small distance (winter position) between the grille parts. This is achieved by placing the axis of rotation of the grating parts closer to the part forming the tip of the grating part in the first position (summer position) than the part forming the tip of the grating part in the second position (winter position).

However, when using a support frame for grating parts which is axially (and horizontally) adjustable with respect to the support frame included in the device, the height of the grating parts can be adjusted by correspondingly adjusting the height of the support frame relative to the support frame.

Other features of the invention will become apparent from the following description, taken in conjunction with the accompanying drawings, in which 4 65155

Fig. 1 shows a perspective view of the cattle barrier in the first position (summer position), Fig. 2 shows a side view of the same as Fig. 1, Fig. 3 shows a side view of the cattle barrel in the second position (winter position), Fig. 4 shows the cattle barrel seen from the side. Figures 5 and 6 show parts of the ridge of Figure 4 in two different positions in cross-section, Figures 7 and 8 show parts of the ridge of Figure 4 in two different positions, respectively, in longitudinal section, Figures 9 and 10 show details of the ridge of Figure 4 seen from above, 11 shows an alternative detail in the figure corresponding to Fig. 5.

The livestock grate according to Figures 1-3 comprises a plurality of elongate grate parts 10 supported in an upper, vertically and horizontally movable frame part 11 connected to the lower, fixed frame part 12 by means of four separate, longitudinally adjustable hinge joints 13.

In the embodiment example shown, each pair of grating parts 10 consists of two parallel cylindrical steel tubes 10a, 10b, which are welded or otherwise fixedly connected to each other. The second steel tube 10a is rotatably mounted at both ends by means of end pins 14 on suitable bearings on the side pieces 11a, 11b of the frame parts 11, so that the grate parts can be pivoted from the position shown in Figures 1 and 2 to the position shown in Fig. 3. Figures 1 and 2 show the grate parts in the first position, i.e. in the so-called summer position, in which relatively large spaces are formed between the grate parts so that domestic animals etc. can be prevented from passing over the cattle grid. In this position, the steel tubes 10a, 10b are turned to a position where they are vertically superimposed. Figure 3 shows the grate parts in a second position, i.e. in the so-called winter position, with a minimum distance between the grate parts, the steel tubes 10a, 10b being turned to a position where they are horizontally parallel and the sides facing each other with respect to the adjacent grate parts.

In the illustrated application example, only four grating parts 10a, 10b are shown, but in practice any number of grating parts can be used as required. It is self-evident that other shapes of grate parts can be used, and that instead of using two identical, cylindrical steel tubes in each pair of gratings, for example, one cylindrical steel tube and one steel tube with an elongated (somewhat flat compressed) tube cross-section can be used.

In the first position (summer position) shown in Figures 1 and 2, the steel tube 10b is inserted into the groove 15 in the frame part 12 and rests against the bottom and sides of the groove 15.

In the second position (winter position) shown in Fig. 3, the steel tube 10b and the steel tube 10a are fixed to a plane above the groove 15 and press against their respective vertically upwardly directed apex of the support member 16, which laterally delimits the grooves 15. The top of the support members 16 is rounded a support base adapted to the external contours of the steel tubes. As shown in Fig. 3, the three middle support portions form a support for the first steel tube 10b of the first grate portion and the second steel tube 10a of the adjacent grate portion.

Figure 1 shows four separate articulated arm joints 13 between the frame part 11 and the frame part 12. Each articulated arm joint 13 comprises a screw shaft rotatably mounted about a horizontal axis on the mounting plate 18 in the support frame 12 and further mounted rotatably about a vertical (or substantially vertical) axis on the mounting plate. The connecting part 13 may therefore be provided with an upper head 20 τ— 6 65155 surface adhering to a corresponding base in the mounting plate 1Θ with a spherical notch. The screw shaft of the articulated arm joint 13 is substantially provided with external threads of the support member 21 which co-operate with the internal threads of the nut 22 attached to the side members 11a and 11b of the frame member 11. The nut 22 is rotatably mounted about a vertical axis in the side member 11a of the support frame 11. At the top, the connecting part is provided with a square head 23 with a hand crank (not shown) or other similar tool for gripping to rotate the connecting part as required.

Figure 2 shows the cattle grid in the operating position in the first position (summer position). A small plate-like portion 24 is pivotally mounted on each end edge of the cattle grid.

In Figure 2, the second plate-like portion 24 is turned down between the ridge grid and the second end edge of the associated road portion 25, and the second plate-like portion 24 forms an connecting portion between the ridge grid and the end edge of the associated road portion 26. Figure 3 shows the plate-like parts 24 in the opposite position. The drawings show that in the first position (Fig. 2) the cattle grid is adjusted to a somewhat higher level (practically 15 mm higher) than in the second position (Fig. 3), and at the same time the support part is moved horizontally from left (Fig. 2) to the right (Fig. 2). 3).

In order to adjust the cattle tine from the first position to the second position, the frame part 11 is raised vertically upwards with respect to the frame part 12 by means of screw threads on the screw shaft. The frame part 11 is then moved horizontally from left (Fig. 2) to the right (Fig. 3) so that the grate parts 10 can be turned clockwise and thus move the steel tubes 10b upwards from the grooves 15 to a position in line with the steel tubes 10a. By then lowering the cavity part 11 again, the steel pipes 10a, 10b can rest against their bases at the top of the support parts 16. The grate parts are secured in place in the position shown by tightening the articulated joint 13.

In order to lift the steel pipes 10b when turning the grating parts from the first position to the second position, special lifting members can be used, which run below the row of grating parts. Such lifting means may possibly be used separately or can be used via connecting parts, for example in such a way that a push rod-shaped lifting arm connected to a nut in each respective connecting part lifts the steel tube part with a slightly larger lifting movement than the support frame lifting movement. , at the same time as they are lifted upwards, also move the support frame 11 from left to right. However, raising the support frame and then moving the support frame from left to right normally makes additional lifting members unnecessary. For example, in order to achieve the desired turning of all the grating parts, all the steel pipe parts 10b can be connected to a common bar member and the bar member can be actuated by a common lever or a similar acting member. The rod-shaped member can possibly be connected to a vibration damping member so as to prevent the grating parts from vibrating when driving over the grating parts. Reference numeral 27 shows flanges which go somewhat inwards on the grate parts.

The flanges 27 prevent the grate parts 10b from turning upwards with respect to the desired upper position (winter position).

Figure 4 shows a livestock grate with generally the same structure as shown in Figures 1-3, but with some deviating details.

In Figures 1-3, plate-like parts are used at opposite ends of the grate at the transition point between the carriageway and the grate, but according to Figure 4, such plate-like parts are omitted. For this reason, care has been taken to ensure that the girder parts 10a, 10b completely fill the space between the intersecting road sections 25, 26.

In the application example according to Fig. 4 (see also Figs. 5 and 6), the upper rectangular frame part 11 is used in the same way as shown in Fig. 1. The longitudinal L-shaped frame profiles have tube lugs 14a attached to the L-shaped vertical part, which form an inner pivot bearing at the ends.

Figures 5 and 6 show a bracket 30 with which the lower pipe part 10b can be raised up to the same level as the pipe part 10a. The lifting of the pipe part 10a takes place first after the upper frame part 11 has been lifted up to a suitable height above the lower frame part 12 by means of the shafts in the articulated arm joints 13. This causes the upper frame portion 11 and its associated tube portions 10a 65155 Γ θ to be moved to the right in Fig. 7 to approximately the position shown in Fig. 8 while the tube portions 10b are guided up and turned to the left by the brackets 30, and then the lower frame portion 11 is guided down 10b in place on the supports in the support members 16 as shown in Figure 8.

It can be seen from Figures 4-10 that the shaft 31 can be moved horizontally in the elongate hole 32 in the plate 33 by the frame part 11, the spindle being provided with a support head 34 and 35 at the ends of the plate, respectively. The screw threads 35 of the mandrel 31 engage the corresponding threads in the nut-forming plate 37, which plate 37 is mounted around a horizontal axis in the lower frame part 12 of rotation.

Figure 11 shows a rubber cuff 38 attached to the upper side of the plate 37 and a cover 39 attached below the plate 37 to protect the screw threads of the mandrel 31 from dirt.
