Definitions

  • Mobile scaffolds for processing walls are known in a variety of embodiments. They are generally designed as a rigid unit and have one or more platforms that can be reached with ladders and serve as standing areas for working people and as storage areas for work equipment and materials.
  • vehicles are known which have a boom which can be pivoted about horizontal and vertical axes and, in some cases, also extends telescopically, at the end of which a work platform is arranged which is remote from the vehicle. The movements of the boom can be controlled from the work platform, but not the movements of the entire vehicle.
  • a mobile scaffold is known from DE-A-2254525, which essentially consists of an ordinary truck for moving movements on a standing surface and a guide device for upward and downward movements of work tools.
  • the truck To work on a wall, the truck must be controlled by a driver parallel to the wall. It therefore depends on the skill of the driver whether the truck can be controlled in such a way that the working tools neither move away from the wall nor are there any excessive pressure that could damage the wall. Controlling the driving movements of the truck should therefore require the driver's full attention; the driver will therefore hardly be able to monitor the effect of the work tools and make sure that they fulfill their purpose, for example brushing a layer of dirt, but not a protective coating, off the wall.
  • the invention has for its object to design a mobile scaffold for machining walls, esp. For cleaning the inner walls of drinking water containers, in such a way that it can be used easily and in a time-saving manner by a single person.
  • the chassis that is moved along a wall is constantly striving to approach the wall because of the arrangement of the wheels according to the invention.
  • the deflection rollers constantly counteract this endeavor. Slippage necessarily occurs on the second impeller, which is small but sufficient to deliver the force, with which the deflection rollers are pressed against the wall. The result is that the chassis constantly follows the course of the wall.
  • the mobile scaffold shown has a chassis 10 which is formed by a substantially triangular, horizontal frame in plan view and has a front side 12 which, in the use position, is arranged parallel to the wall to be machined. On the front 12, two wheels 14 and 16 are mounted; a third wheel 18 is mounted on the end of the chassis 10 remote from the front 12.
  • the impeller 14 has a running direction parallel to the front 12 and can be driven by means of a traction motor 20 such that the impeller 14 as the front impeller pulls the entire device.
  • the impeller 16 is mounted in a fork 22 which is adjustable about a vertical steering axis 24 and is normally fixed in a position in which the running direction of the impeller 16 extends at an acute angle in the direction of travel towards the wall to be machined, the chassis 10 therefore endeavors to approach the wall.
  • a bracket 26 which extends at right angles to the front 12 to the front and has an adjustable length.
  • a deflection roller 28 is rotatably mounted about a vertical axis. Because of the setting of the impeller 16 described, the chassis 10 is always moved when driving forward so that the deflecting rollers 28 are pressed against the wall to be machined and roll along it.
  • a mast 30 extends vertically upward from the front 12 of the chassis 10.
  • the mast 30 consists of two parallel spars 32, which are connected to one another by cross bars 34 like a ladder.
  • the mast 30 can be subdivided into a plurality of sections 36, each of which has two cross rungs 34 and, in the use position, engage in such a way that the mast is generally rigid.
  • a pair of vertical stands 38 are fastened, in the upper end regions of which the mast 30 is pivotably mounted about a horizontal axis 40 parallel to the front 12.
  • a pipe 44 is articulated at the end of the chassis remote from the front 12 by means of a joint 42; a rod 46 is held in this, which is connected by a further joint 48 to the upper end region of the mast 30.
  • a support 50 is formed which holds the mast 30 in a selected position which is more or less exactly vertical in accordance with the wall to be worked.
  • the support 50 has a length adjustment device 52 so that the desired position of the mast 30 can be reached and maintained even if the chassis 10 is not exactly horizontally arranged due to an inclination of the floor on which the wheels 14, 16 and 18 are located.
  • the length adjustment device 52 is a threaded spindle in the example shown, which is rotatably supported on the joint 42 about its own axis and is screwed into a nut thread at the lower end of the tube 44.
  • the support 50 is longitudinally elastic within certain limits.
  • the tube 44 contains a suspension 54, not shown in detail, for example a helical compression spring, on which the rod 46 is supported within the tube 44. Starting from the position shown, the rod 46 can thus be pushed further into the tube 44 against increasing resistance. Unintentional complete pulling of the rod 46 out of the tube 44 is prevented by means of a conventional type, for example flange and collar.
  • a lifting motor 56 is arranged, by means of which a lower shaft 58 of a lifting device 60, which is mounted on the two bars 32 and is parallel to the axis 40, can be driven.
  • a lower sprocket 62 is fastened on the shaft 58 near the two spars 32.
  • a corresponding shaft 64 with a pair of chain wheels 66 is mounted in the two spars 32 at the upper end of the mast 30.
  • Each pair of sprockets 62 and 66 arranged one above the other is wrapped in an endless roller chain 68.
  • the two spars 32 form guides for a device carrier 70 that can be moved up and down along the mast 30.
  • two brush rollers 72 are mounted on the device carrier 70, which are arranged one above the other parallel to the axis 40 and by a common motor 74 also arranged on the device carrier 70 are drivable.
  • a further pair of jibs 76 projecting forward is fastened, on each of which a deflection roller 78 is also mounted with an approximately vertical axis of rotation parallel to the mast 30.
  • a unit 80 is also arranged on the chassis 10, which supplies the brush rollers 72 or the nozzles arranged in the vicinity of the device carrier 70 via lines 82 with water, the pressure of which can be adjusted in accordance with the cleaning task.
  • a control box 84 is arranged in the rear area of the chassis 10, from which all functions of the frame and the devices carried by it are controlled.
  • the implement carrier 70 is moved up and down while the brush rollers 72 rotate. After one or more upward and downward movements of the device carrier 70, preferably in its lower end position, the chassis 10 is moved further in each case by a distance which is somewhat less than the length of the brush roller 72.
