Abstract

The invention is applicable in the construction industry and can be used there expediently in reconstruction work. The invention is intended to reduce the amount of basic resources, increase the utilization rate of existing equipment and thus reduce the cost of the economy, especially in the reconstruction of old buildings. It was the task to create a way to use mobile work scaffolding with height-adjustable platform optionally also for the vertical and horizontal transport of material, the cargo is to be guided through Fensteroeffnungen into the building interior. According to the invention, the object is achieved by an additional device in which a load arms, load bridge and querverschiebbarer support plate existing load device is pivotally mounted on the platform, the load arms rest against the stoches of load torque fuses, each one load arm is assigned to one of the independently connected load torque fuses.

Description

Field of application of the invention
The invention is useful applicable in construction and can be used there, especially in reconstruction work on residential, corporate and industrial buildings advantageous.
Characteristic of the known technical solutions
There are masts known in which a working platform on a, usually triangular cross-section having support pole is arranged adjustable in height. The support mast, which can be placed on a manual undercarriage, consists of individual mast shots, which are placed on each other according to the required working height and anchored at certain intervals on the wall of the building.
These masts are structurally and safety designed so that they can only be used as a pure work scaffolding. Their use for the transport of material is not possible for reasons of work safety. The height-adjustable platform also has neither a suitable load-carrying means, nor does it offer the possibility of a horizontal material transport in the interior of the building. For the transport of material, for example, for the purpose of refurbishment therefore special equipment, such as construction hoist or the like must be used.
Such construction hoists are known in various forms. In one of these devices, a vertical boom transports a boom, which is inserted into the window opening of the building without load. For operation, a pendulum support is folded down from the boom inside the building. The load is then lifted vertically by means of a trolley movable on the boom and retracted horizontally into the building. The main disadvantages of this device are a high space requirement, the need for a separate pre-assembly for each floor and the impossibility of use in small window openings, as they are particularly common in old buildings.
In another known construction hoist, two platforms, which serve to receive containers or pallets, are conveyed vertically on an elevator mast. The horizontal transport via flaps or mounted on the building consoles, which is a disadvantage that the conveyed can not be driven by the device in the interior of the building and no backup of the cargo in the horizontal movement. The necessary consoles also prevent the device from being used to reconstruct inhabited buildings. An employment for work in the roof zone of the buildings is likewise not intended. All known solutions also has the disadvantage that separate equipment must be used for work on building facades or in the roof zone and for the transport of material. This results in addition to a high cost of basic means and the associated costs also to a high Montägeaufwand and in many cases also to a reduction in the degree of utilization of the devices.
Object of the invention
The invention is intended to reduce the necessary expenditure on basic resources, increase the utilization rate of existing equipment and thus reduce the economic outlay for working time and material, in particular in the reconstruction of old building substance.
Explanation of the essence of the invention
The invention has for its object to provide an additional device for mobile scaffolding with height-adjustable work platform, which makes it possible to use the device either as work scaffolding or aJs device for the vertical and horizontal transport of material, the transported transported through window openings into the interior of the building shall be. .
According to the invention the object is achieved in that on the platform a load device is articulated, which consists of vertical load arms, a horizontal load bridge and a transversely slidably mounted on the load bar support plate. The load arms are applied to the rams of load torque fuses, which are also arranged on the platform. Each of the two load arms is assigned a load torque fuse independently connected by the other, wherein a load torque fuse for the vertical movement of the load device and the second is provided for the horizontal movement of the support plate. In order to arrange the load device either right or left side, two bearing blocks for articulated mounting of the load arms and two load torque fuses are provided on both narrow sides. The transverse displacement of the support plate is expediently carried out via support rollers which are arranged on the load web, wherein the feed is mechanically brought about by means of a transmission brake motor.
embodiment
The invention will be explained in more detail in the following embodiment. In the accompanying drawing show:
1 is a view of a mobile mast with attached attachment device. FIG. 2 is the side view of FIG .. 1
3 shows the enlarged view of a load torque fuse in section The height-adjustable on the support mast 1 and height adjustable by means of rollers and racks platform 2 has on its narrow sides bearing blocks 3. The bearing blocks 3 with associated hinge pin 3 'carry a two load arms. 4 , Laststeg 5 and support plate 6 existing load device. The support plate 6 is arranged by means of support rollers 7 transversely displaceable on the load web 5; It is used to hold piece goods or in pallets befindlichem material that is for the purpose of Altbausanierung first vertically and after reaching the intended height to be transported horizontally through window openings 8 or the like. Into the interior of buildings. The material to be conveyed is supported on a defined load surface of the support plate 6. The horizontal feed of the support plate 6 via a Getriebebremsmotor 9, while the vertical transport takes place in a known manner by means of the height-adjustable platform 2. In order to prevent unintentional overloading of the load device both the vertical transport and the horizontal transport, two independently acting Lastmomentensicherungen 10 are arranged on the narrow sides of the platform 2 so that the load arms 4, as shown in Figure 3, on the plungers 10 'of Load torque fuses abut.
With inadmissibly high loading of the load torque fuses 10 of the vertical transport is prevented by power interruption, while the second load torque fuse 10 interrupts in the extended support plate 6 and unacceptably high load in the same way, the power supply for horizontal transport. The permissible load is determined by the torque which results from the distance between the articulated boom 3 'and the plunger 10' and the spring force of the springs 10 "located in the load-torque safeguards 10. Bearing blocks 3 and load-torque safeguards 10 are located on both sides of the Platform 2, so that the load device can be arranged either right or left side.
By means of the device according to the invention, it has become possible to use the lifting platforms, which hitherto could only be used as work scaffolding, for transporting material, whereby this can be transported into the building interior or into the roof zone. Similarly demolition masses or dismantled objects can be transported out of the building.
The invention is particularly advantageous for reconstruction work or Altbausanierungen suitable because it makes it possible to pass the cargo through window openings. The assembly and disassembly is possible with little installation effort, without the need for special lifting equipment. Likewise, the retooling requires little time, so that the mast can be used either as a work scaffold or as a transport device. This makes it possible to use existing devices more flexibly and to increase their degree of utilization.
