Definitions
- the present invention relates to a working platform for drilling rigs.
- Working platforms are used wherever a floor is not suitable for carrying a working device, for example a drilling device, or for carrying an operator for the working device. This may be due to the relative distance of the floor to the place where the work is to be done.
- the floor can be so far below the place of work that an implement placed on this floor or an implement held by an operator standing on this floor cannot reach the place of work.
- work platforms are also used where the floor is not suitable as a work base.
- a floor may not be suitable for carrying heavy loads, so that heavy equipment placed on the floor sinks into the floor.
- the floor can have properties that do not allow the implement to be safely placed on the floor.
- the floor may have a surface that is too smooth, for example to provide sufficient support for a horizontally drilling implement.
- BESTATIGUNGSKOPIE and to provide a place of work in the area of the place of work. Due to the length of the support means, such work platforms are unwieldy to transport and set up. Furthermore, the construction of these work platforms in shafts accessible from above is complex.
- the present invention has for its object to provide a work platform that can be easily used in a vertical shaft.
- the work platform has a base body and support means for direct or indirect support on a vertical surface. Since the working platform is no longer supported on the floor but, for example, on a vertical surface, for example in the vicinity of the working location, the positioning of the working platform is independent of the floor. This means that the arrangement of the work platform is independent of the distance from the floor to the place of work. This allows it to be made more compact. Furthermore, the construction of the work platform is simplified.
- the work platform according to the invention only needs to be lowered into the shaft through the shaft opening until it has reached the area of the work site. Immediately below this place of work, it can be supported on the vertical surface. be positioned without the individual components first having to be lowered onto the floor, which may be a bit lower.
- the stability of the work platform is independent of the nature of the floor. Regardless of whether or not the floor is load-bearing, in particular if it has become soft due to moisture in a shaft or the shaft environment, the working platform according to the invention can offer a stable basis for work on the side surfaces of the shaft.
- the work platform according to the invention is also suitable for use in pits, for example when laying pipes using the burst lining method.
- this working means is movably connected to the base body by means of connecting means between working positions.
- Working equipment is understood to mean any means that is to be provided from a work platform for the work to be carried out. This is usually a work surface or mounting plate.
- the work surface provides means from which an operator standing on it can hold and / or operate an implement.
- a mounting plate is suitable for holding an implement, for example by connecting it to the mounting plate or placing it on the mounting plate.
- a working tool can also be a working tool, for example a drilling tool, which is held in the working position by the connecting means on the base body.
- the connecting means are preferably created so that they are not rigid
- connection of the work equipment with the base body but allow movement of the work equipment relative to the base body. This enables the work equipment to be brought into the correct working position. However, it is also possible to move the work equipment into several working positions one after the other from a working platform supported on the vertical surface and to carry out these work.
- the connecting means can pivot, rotate or adjust the height of the work enable by means. It is possible that the connecting means only allow swiveling, turning or height adjustment. However, connecting means are preferably provided which enable combinations of these types of movement. The movements are preferably made infinitely variable by the connecting means, so that the working means can be brought precisely into the working position.
- the movement possibilities of the work equipment can also make it possible to avoid obstacles, such as crampons, on the vertical surface when the work equipment is moved to the place of work.
- the work platform according to the invention can be used wherever work at a place of work e.g. must be performed on a vertical surface.
- the vertical surfaces are usually the side walls of a shaft or a pit, but can also be the vertical boundary surfaces of other rooms. Vertical surfaces are not only understood as vertical surfaces, but as essentially vertical surfaces on which conventional work platforms with adjustable feet cannot be placed.
- the work platform can also be used in a shaft, the central longitudinal axis of which is oriented at small angles to the vertical.
- Support means are understood as means which are suitable for supporting a work means directly or indirectly on a vertical surface.
- This can be a strut which supports the base body from below and is at an angle to the vertical, so that it is supported on the vertical surface below the base body.
- the base body is preferably held by a plurality of support means which are supported on opposite vertical surfaces, for example shaft walls.
- the base body is preferably held by frictional engagement.
- the support means must be arranged so that they rest at least partially flat on the vertical surface.
- the surface of the work equipment is preferably formed such that a good frictional resistance against vertical slipping of the work equipment is generated.
- the support means are preferably arranged on the base body. However, they can also be provided on the work equipment connected to the base body and support this work equipment directly. With such an arrangement, the base body is mainly used to provide a point of attack for means for lowering the working platform into the desired position. The actual fixation of the work equipment in the desired position then takes place via the support means provided on the work equipment.
- the support means therefore preferably have support plates. These are used to lie flat on the vertical surface and to support the base body. They can be connected to the base body in such a way that their alignment can be adjusted in order to allow a flat contact with the vertical surface even with vertical surfaces that do not run perpendicularly.
- the support plate of at least one support means is preferably connected to the base body via movement means for moving the support plate in and out relative to the base body. This makes it possible for the working platform with retracted support means to be lowered into the shaft through a narrow opening, for example a shaft opening, and for the base body to be supported well by extending the support means at the intended work location even with large cross sections of the shaft.
- a work platform with retractable and extendable support means enables the work platform to be supported off-center in a shaft. This is done by extending the support means to different extents.
- a work platform can be supported in various environments, for example different shaft geometries, since the support means that can be extended and retracted can be adapted well to the surroundings of the place of work.
- Movement means are means that allow the support plate to be moved relative to the base body and to be fixed in a support position relative to the base body.
- these are telescopic elements, such as a cylinder-piston element.
- it can also be a shaft that is held releasably in a clamp.
- the support means preferably have fastening means for connection to the vertically running surfaces. These can be dowels, anchors, nails or tips.
- the fastening means can be arranged on elements of the support means provided especially for them, but they are preferably provided in connection with a support plate and fix it to the vertical surface.
- a good, easy-to-use movement of the working medium is achieved if at least one telescopic element is provided as the connecting means.
- the working means connected to the base body can be moved vertically, obliquely or horizontally and held in the desired working position.
- a plurality of telescopic elements are preferably articulated to the working means at different points, so that the working means can also be pivoted into differently oriented working positions and held there.
- a rotary device is also provided as the connecting means. This can turn the work equipment into the desired working position, for example around a vertical axis.
- the connecting means can also be arranged so that the telescopic elements are connected to the rotating device, so that the working means can be both rotated into the working position and pivoted.
- a swivel arm is provided as the connecting arm. This carries the work equipment and is connected to the main body.
- the swivel arm can be rotatably mounted in the base body. It can be designed to be pivotable about its connection point with the base body. It is preferably of multi-part and multi-joint design, so that it can be moved with many degrees of freedom in order to bring the working medium into the desired position.
- the work platform can have a safety rope for connection to a safety point located above the work platform.
- the safety rope is used to hold the work platform in case the support fails due to the support means.
- a safety rope can be a rope, in particular a steel rope, a chain or some other means that can be flexibly guided from the work platform to a safety point.
- a securing point can be a fastening point, for example a crampon, in a shaft.
- fastening points outside a shaft for example anchor elements rammed into the ground next to the shaft opening, can also be used as a securing point.
- a ring placed around the shaft opening the diameter of which is larger than the shaft opening, can be used as a securing point.
- the work platform has at least one cushion, which on one side facing the shaft wall
- Air cushion can support an even application of force to the necessary support force in the shaft wall.
- An upholstery is understood to be any upholstery which can be arranged between a support means and a shaft wall and which uniformizes the introduction of force into the shaft wall.
- air cushions are cushions filled with medium, in particular with flexible boundary walls.
- the medium can be air but also any other medium that can flow in the cushion, for example a fluid or a granulate.
- the cushion can also consist of foam or other compressible media.
- the cushion preferably has the same circumferential dimensions as the surface of the support means, for example the support plate, facing the shaft wall.
- the upholstery can also have any other shape and, for example, be designed as a tom or ring surrounding the work platform.
- the air cushion preferably has a shape adapted to the shaft wall. As a result, the cushion can introduce the supporting force into the wall particularly well over a large area.
- the work platform according to the invention is particularly preferred for creating connections, in particular of
- House connections for example for fiber optic cables, used in a shaft.
- a work platform sitting on the shaft floor has always been used for this purpose, for the construction of which people had to enter the shaft and had to build the work platform from the shaft floor.

- a drilling device 6 with a drill rod 7 is connected to the working means 5.
- the working platform 1 is inserted into a shaft 8 and is supported on the shaft walls 9.
- Safety ropes 10 are connected at one end to the work platform 1 and at the other end to a safety point 11 in the form of a ring placed over the shaft opening 12.
- the connecting means 4 is designed as a telescopic element in the form of a cylinder-piston element, which enables a vertical movement of the working means 5 relative to the base body 2 and can hold the working means 5 in a working position relative to the base body 2.
- the base body 2 has the shape of a cylinder, at one end of which a support means 3a in the form of a support plate is attached.
- a movement means 13 in the form of a piston is inserted into the base body 2 and has a support means 3b in the form of a support plate at its end facing away from the base body 2.
- the support means 3b can be moved in and out relative to the base body 2 by the cylinder-piston connection between the movement means 13 and the base body 2.
- it is lowered into the shaft through the shaft opening 12 by means of the safety ropes 10 with the support means 3b retracted.
- the support means 3b is extended by moving the movement means 13 out of the base body 2 until it creates a clamp in the shaft 8 with the support means 3a, which holds the working platform 1 in the desired position in the shaft 8.
- the working means 5 is brought into the desired working position via the connecting means 4 by the cylinder-piston element being extended or retracted.
- a connection hole 14 can be drilled into the shaft wall 9 with the drill rod 7 of the drilling device 6.
- the working means 5 can be brought into a different working position by further extending the connecting means 4 for working at another working location without the base body 2 having to be changed in its clamping position.
- FIGS. 1 and 2 show the working means 5 in a top view.
- the drilling device 6 with drill pipe 7 arranged on the working means 5 is arranged in a position rotated to the position shown in FIGS. 1 and 2.
- This change in the alignment of the drill pipe 7 is achieved by repositioning the drilling device on the working medium 5.
- the change in the orientation of the drill string 7 can, however, also be achieved in that the working medium is rotated relative to the base body 2.
- the connecting means 4 allows a free choice of the location at which the base body 2 is supported on the vertical wall.
- the base body 2 can be supported in a position that is particularly well suited for support, because the vertical surface there is particularly stable, for example, or has a high coefficient of friction.
- a variety of working locations can be reached from one position, so that repositioning of the base body 2 is not necessary.
