Definitions
- Shaft lining by drilling and blasting is characterized by advantages in the installation of lining and high flexibility to changing rock properties, but must remain competitive with regard to increasing tunneling performance - especially with machine sinking.
- the process consists of the operations of drilling and blasting the bottom of the shaft, unloading and removing the blasted heaps using buckets and finally creating the shaft lining from the working platform in the shaft.
- Orange peel grabs were used for loading work on the bed from the middle of the 20th century to the present day. Such a system is attached under the working platform and is operated from the floor by two people. Of these, one is responsible for opening and closing and the other for positioning the grab on the shaft bottom. Because the gripper can only penetrate the heap using its own gravity, the second man partially “drops" it with a vengeance, which leads to can lead to dangerous situations on the sole, especially since nowadays there are hardly any experienced operators for such systems.
- the object of the present invention is therefore to create a work platform for installing fixtures in vertical shafts in mining and tunneling, which is characterized by an improvement in the sinking performance to be achieved and occupational safety while reducing the required manpower in the hazardous area.
- this new concept also enables work to be carried out in the shaft in parallel, thereby significantly increasing not only the sinking performance but also work safety. While the shaft lining is being brought in on the working platform, the blasted base (the mountains) is remotely controlled by the shaft excavator without an operator or is automatically loaded into buckets and removed. Thanks to the parallelization of the normally sequential work, several hours can be saved on an entire work cycle. This significantly increases the sinking power.
- a device assigned to the working platform is used to adjust the height of the shaft excavator is to be understood in such a way that the respective shaft excavator is moved indirectly via a suitable device.
- the shaft excavator is thus (also) moved and positioned as a function of the method and/or pivoting of this unit.
- Under such a device is here z. B. understood a telescoping tube or a suspended, adjustable platform of the working platform.
- a telescoping tube is guided in the longitudinal axis of the work platform, at the lower end of which a shaft excavator is arranged.
- the shaft excavator assembly is (also) adjusted in height thanks to the telescoping central tube.
- the telescoping central tube or the lowest working platform forms, so to speak, the warehouse for the shaft excavators used for loading and/or transporting out the blasted heaps, together with the units required for this assembly.
- a console is provided for connecting the shaft excavator.
- the console has a dual function if the console is used for moving and/or pivoting the shaft excavator, but the exclusive option of moving or pivoting is also conceivable.
- the shaft excavator can be operated from a work platform or from above ground.
- the filled The bucket can be positioned and emptied automatically and with great precision anywhere in the area of the shaft bottom over the bucket.
- a preferred embodiment provides that the stored position of a scavenging bucket is used as a reference value for positioning and/or emptying the backhoe.
- the filled backhoe can be automatically positioned and emptied exactly over the bucket from any point on the bottom of the shaft by pressing a button on the operating unit. This is done with a high degree of precision and uniformity thanks to the alignment of the shaft excavator and its assembly with boom, stick, backhoe etc. that is possible in this way.
- the return to the last working point is also automatic, so that the operator only has to fill the backhoe with debris.
- these computer-aided movement sequences and positionings can be carried out faster, more precisely and more safely than with any manual control.
- Such a loading cycle can be further optimized with regard to the work to be carried out on the shaft bottom, in that the shaft lining is brought in on the working platform and the blasted bottom is loaded and removed into buckets at the same time.
- the invention also relates to a shaft excavator for a working platform according to at least one of patent claims 1 to 16.
- the invention is characterized in particular by the fact that a working platform for the installation of fixtures in vertical shafts in mining and tunneling is created, which is essential for safety underground contributes to the sinking of the shaft by the processes of loading away and removing the blasted heaps being carried out almost automatically.
- the deployment of personnel in this critical area is obsolete.
- Two different solutions are proposed for this, namely a telescoping tube which is guided in the longitudinal axis of the work platform and at the lower end of which at least one shaft excavator is positioned.
- the alternative teaches a lowest, possibly additional working platform for the working platform with appropriate suspension.
- the shaft lining While the shaft lining is being brought in on the working platform, the blasted base is loaded into buckets and removed unmanned by the shaft excavator.
- the shaft excavator can be operated from the work platform or from above ground.
- there is potential for optimization with regard to the work to be carried out on the bottom of the shaft because the loading cycle can be partially automated.
- the shaft excavator In addition to the pure loading activity, there are other possible uses of the shaft excavator that can significantly speed up the work process. This includes the drill-proofing of the base, i. H. removing the "last cm" of heaps in front of the solid rock using a suction unit attached to the quick coupler, tearing open the shaft joint and using a powerful attachment milling machine and a drill rig to drill the blast holes can be seen as helpful.
- FIG. 2 a work platform with a telescopic tube in the extended position
- Figure 8 is a working platform with additional working platform in front view
