Description

Pallet for pressurized gas cylinders

The innovation relates to a pallet for pressurized gas cylinders with a foot group consisting of an essentially right-angled floor frame with a circumferential floor bracket arranged above it, separated from the floor frame by supports, with vertical bars as well as the vertical bars on three sides connecting side bars, the fourth Side as loading side with a hinged loading flap closed up to about half its height and in the area the upper end of the vertical bars is secured by means of a hinged safety bar.

Bottle pallets for the transport of pressurized gas bottles are tailored to the particular conditions that

the handling of pressurized gas cylinders requires. Essential there is safety in handling the loaded pallet, although it makes no difference whether the The pallet is fully loaded, partially loaded or even loaded with pressurized gas cylinders of different contents - and thus of different heights. The pressurized gas cylinders stored in the pallet must not fall over; there must be no risk of pressurized gas cylinders falling off the pallet, and finally the pallet must be so stable in itself that it safely carries the considerable masses of the pressurized gas cylinders. For this reason such bottle pallets are welded together from metal profiles. In the rough handling of such pallets, which have also been used for a long time in industrial environments Are exposed to weathering, - is for the preservation of their Stability a long-term corrosion protection necessity. Here has the use of galvanized steel profiles proven. The pallet is loaded via its loading side, which contains a hinged loading flap and which has a hinged safety bar at the top. In the case of the pallets known on the market, the loading flap is mounted in the two adjacent vertical bars by means of a continuous axis. They are secured in the upright position by means of locking devices similar to those of a vorreibex. When folded down we "' the loading flap carried by its continuous axis of rotation. The axle bends during loading a; the loading flap is no longer easy to move. The foldable safety bar is in the unfolded state by a locking pin or by a Latch-like lock secured. A backup in

folded down for trams is not intended. The handling of these pallets is conditioned by the handicaps due to the protective gloves are not easy; Accidents cannot be ruled out.

This is where the innovation comes in, which is based on the task of developing a generic cylinder pallet for pressurized gas cylinders in which the loading flap is securely attached the pallet frame is articulated and in the folded down state during loading cannot experience a deformation that restricts mobility, in which the loading flap is securely attached in the unfolded transport state, in which the safety bar in the unfolded State automatically engages and is locked in the folded-down transport state, in which the movable parts are easily interchangeable, in which the construction is fully galvanized in the assembled state which is easy to use and which can ultimately be produced simply and economically.

Falling back is prevented. To trigger the lock, the handlebar is raised; it is then free to lower in the transport positions.

Alternatively, it is proposed that the means for securing the unfolded safety bar as a safety catch are formed, the securing pawl having a recess that can be placed against the axis and an approximately standing at right angles to the longitudinal extension of the WinV.elhebels Has projection and wherein the length of the locking part of the drop lever is the distance from the axis of the Drop lever from the inside of the horizontal leg of the profile of the lateral upper horizontal beam, which receives the guide rod for the hinged safety bar, corresponds to. Through this embodiment the securing means for the unfolded state of the safety bar a simple stamped part is necessary, which is easily rotatable within the fork bearing. The safety catch falls when the bar is raised automatically in the locked position due to the force of gravity acting on it and is caused by a torque fixed in the locking direction exerting safety bar in this locking position. To trigger the fuse, the Safety bar rotated against its closing direction, the fixation of the safety catch is canceled with the the other hand can use the safety catch on the one used for operation. Glove-shaped protrusion raised and thus be brought out of the blocked position. The backup holir. can then be lowered. Further it is proposed that the hinged strut, which is displaceable along the guide rod, preferably one has locking lug attached to a fork of the sliding bearing, which is located in recesses in the horizontal leg of the lateral side holding the guide rod]

upper Horizon ta lho lines engages and that at the opposite end of the safety bar a spacer bolt is provided / which engages in corresponding bolt holes in the horizontal leg of the opposite lateral upper horizontal bar / with recesses and bolt holes are arranged corresponding to each other and the safety bar a plurality of by the arrangement of Recesses and bolt holes given distance from the rear upper horizontal spar can take. By engaging the safety bar on both the side of the sliding bearing and on the side of the free end, the safety bar is fixed on both sides. The choice of the distances is determined from the bottles diameters, so that it is possible to adjust v © n bottles in a pallet and set these bottles with the shifted distance corresponding to the backup spar an _f two or üiehr rows.

Another proposal is characterized in that the two lateral upper horizontal bars have shackles. This makes it possible to not only use the pallet in loading harnesses that interact with the lifting eyes provided on the four vertical bars, but also in two-hook loading harnesses. Furthermore it is proposed that at least on the two sides, approximately in the middle between the bottom bracket and the horizontal bars, central horizontal bars are provided, which are preferably directed with their apex outwards Angle profiles are formed »These middle profiles also allow smaller bottles with a lower height can be safely set.

suggested that at least from both sides of the Middle horizontal bars: at an angle of approximately 45 ° to the vertical bars, upwardly extending load distribution struts are provided and that these load distribution struts and the legs of the lifting eyes are positively connected to one another. A favorable load distribution is achieved through these load transmission struts guaranteed when the pallet is attached to a two-hook loading gear. In addition, these struts also serve to stabilize the upper part of the pallet.

It is also proposed that at least on the rear vertical bars means for fastening tether straps are provided. It is further proposed that the means for fastening the retaining straps are designed as belt hooks, preferably as belt hooks closed to form a bracket. Especially when placing small bottles, which can no longer be detected by the folding safety bar, it is advantageous to use the set To hold bottles in addition with a belt lock. This belt safety device must not be led around the outside of the struts, because when handling, especially when Transporting several pallets, these bump against each other or rub against each other. The means of securing the belt are therefore expedient to attach to the flanks of the vertical bars, which are in the direction of the two, the loading area laterally limiting side rails has. The belts can be fastened here without there being any risk of that the straps come into contact with adjacent pallets; the belts can also be attached here, without the risk of them being damaged by the bottles on the pallet.

Finally, it is proposed that the loaded in the bottom angles bottom plate preferably, a Preßschweißrost, with the bottom angles pointwise welded, the welds the underside of some bars of the framework and the inner edge of the horizontal leg of the base angle * together. This can be addressed as tacking in terms of welding technology
