The invention relates to a conveyor device for Aufoder Downward conveyance of scaffolding parts. Building materials e.g. on scaffolding made of metal,

So far, when on «? or dismantling of metal scaffolding, the scaffolding elements are mainly traded up or down by hand · Such a procedure is uneconomical because the individual ropes are too heavy and unwieldy, so that a disproportionately high personnel expenditure would be necessary. Only in the case of very high scaffolding is a © bea öia eugäesaniater gallows provided, which consists of a boom and a Roll®, over which a wire rope is guided,

this by means of a winch set up on the ground is operated. The scaffolding parts to be conveyed are at the free The end of this wire rope is tied up and wound up on the exterior of the building without any special guidance Parts, for example as a result of the wind pressure, are uncontrollable Can perform visual oscillation movements or fluctuations The process is therefore, especially with high scaffolding, not only stealing, but also dangerous and must be described as unsatisfactory in every way.

So-called Daohdeekeraufsrfige or Sehrägaufsrfige, whose conveyor track mostly runs diagonally to the lauwerk, are also known. However, these elevators are generally unfavorable for use on normal scaffolding, since they require a relatively large amount of space and their structure is too complicated and the devices BU are expensive. The same applies to an even greater extent for setting or docking elevators, which each require extensive work for their construction and are also time-consuming and costly , the scaffolding parts that are already protruding lead uncontrollable movements during the upward or downward conveyance, which endanger the environment of the conveyor track »

The object of the invention is to create a conveying device for scaffolding made of metal ₉ which can be used in a simple manner and without particular difficulties at relatively low costs. Has scaffolding built. Here in particular

the scaffolding itself as a support and reinforcement element of the Feeding device can also be used.

For this purpose, according to the invention, a conveyor rail is used For ice cream, the conveyor frame can be moved vertically up or down separable or inseparable from the outer stand of a vertical frame for metal scaffolding connected in such a way that the conveyor rail will die out at a short distance !!} de » The frame runs parallel to the stand, with its length preferably the length of the stand ent apricot · Ia V «lte? uildwu According to the invention, this rail is designed at its upper and lower end in such a way that the! the ends of two consecutive rails interlock, so that their continuous hoisting rope! ane in YertUcaler Direction length. 3 scaffolding standera is created.

The conveyor rail and the scaffolding stand are inseparably connected, is it sufficient to use suitable, for example flat metal, profile material or? Pipe sections consist » the spacer pieces firmly united with one frame leg Tertikalrahaens forming stand tube su verschwel ε son.

In each case "In! Bell dec profiles have been removed so that the missing part at the upper end just stands at the lower bathtub, eoäase the two close together" the rails sit with the joint again to add to the perfect profile · In order to achieve an automatic coupling can be achieved on the outside of the notched parts at spielBWQise tabs, which, together with the remaining ropes, can accommodate the remaining side of the guide rail attached to the base.

A conveyor frame slides along the rail with a to Receiving the conveyed goods serving basket, which is preferably is attached to the conveyor frame in such a way that it is at a certain angle about an axis running parallel to the conveyor direction can be pivoted to facilitate loading or unloading from the gangplanks of the scaffolding. During the The conveyor cage is in its normal position locked against the conveyor frame.

The conveyor frame is along the conveyor rail, for example by rolling or partially with other means such as guide pins or guide brackets so that it is Do not twist in relation to the rail and also not out of it The rail can jump out or move away from it.

The drive takes place by means of a winch, which is entx ^ eder by hand

operated or by means of an explosion or electric motor operated wM. This winch can, for example, down, so be placed on the ground ^, which is the conveyor frame moving rope over a rail attached above Holle is diverted. And ei - .st α but also I. possible, especially with Yerwendi ron electrically powered Winches, the entire drive mechanism at the top end fasten the conveyor rail su and the conveyor rope without To guide the loop directly to the conveyor frame *

designed so that when two vertically arranged frames are put together, the adjacent rails are automatically coupled to one another so that i ± .0 form a continuous conveyor or slide rail over the entire length of the stand.

So as it is possible to attach the conveyor to a scaffolding or to relocate it to another location while the scaffolding is in place without making changes to the scaffolding itself gu stissen * so it is advantageous ₉ instead of being fixed to the vertical frame The rails 21 can be connected to any desired Tertikai frame. For this purpose, the rails 21 are provided with suitable plug-in or clamping devices at least at one of their ends, preferably at both ends , for example with half-couplings 31 "which are connected to the rails 21 by spacers 32" as shown in FIG Of course, other connections such as Schra ub "or riveted connections" are used. The length of these exchangeable conveyor soles advantageously corresponds in each case to the height of a vertical _frame, but can be used on already existing higher scaffolding

a length of double the height should also be provided corresponds to a vertical frame.

Let it be shown in a TtrtilmlBOhnitt running vertically on the wall of the building _P which is guided in such a way that the vertical frames provided with the conveyor device are visible. In the example chosen, three Vertlkalrahman 1a, 1b, 1o are placed one above the other and fixed by a spacer 2 opposite the wall 3 of the structure. The conveyor rail 21 is guided along the upright tubes 11 of the frames 1a, 1b, 1c in the manner described above. At the upper end of the conveyor rail 21, a bearing device 41 is provided, which is separably connected to the rail. This fork-like bearing device 41 serves as a bearing for the deflection roller 42. It is fixed to the rail by means of a clamping device 43 and can be moved up and down along the rail after releasing the clamping device 43 by means of a friction wheel (not shown in the drawing) and a crank that can be attached to its axis. Instead of a friction wheel, as already mentioned, another device acting by friction to move the bearing part 41 can be provided, which is actuated, for example, by pivoting a lever back and forth, as is already known, for example, from motor vehicle technology for lifting cars.

The conveying device according to the invention offers a large number of advantages over the previously known conveying devices. Besides the fact that the installation of a Gertistaufzuges ■ can be achieved with a lot less effort than previously almost no extra effort at work, or at least little, "&%, the coupling of the conveyor rail to the vertical frame of the framework produces duroh a high degree of mutual reinforcement of the two Parts and thus at least for the conveyor a significant material and weight saving. For the frame, the conveyor rail practically has the same effect as if a frame with three uprights were built into the scaffolding at one point, with the third upright protruding in front of the actual device front and thereby contributing to the stability of the scaffolding. In addition, this vertical arrangement of the conveyor system has the advantage that the forces act vertically on the winch, which is particularly favorable with regard to the distribution of forces, as the capacity for vertically acting forces is particularly high in a metal frame.

Of course, the above-described execution format are only examples through which a different use
