Definitions

  • This invention relates to a system for controlling cranes of the type comprising a frame provided on an outer protective cap, behind which a plurality of control box components are housed, which are accessible by removing the cap from the outside.
  • the control of vehicle-mounted cranes usually takes place with the aid of two control systems or units located on opposite sides of the vehicle in the area behind the driver's cab.
  • Each plant has a set of hydraulic valves whose function is determined by a number of valves corresponding to the number of manually operated control levers.
  • Various functions of the crane such as rotation of the crane pillar, raising or lowering of one or more crane arms, rotation of a ram, loading of a hoist hook, etc., can be activated by controlling the valves.
  • Control systems of this type are through SE 8201833-4 known.
  • the control systems are normally provided with a substantially U-shaped bracket which surrounds the set of operating levers on all sides to protect the set of operating levers so that they are not inadvertently activated, eg by unplanned body contact.
  • a control device for cranes already known in which a plurality of actuating levers are arranged on a pivotally mounted carrier.
  • the operating levers are housed behind a split cap and together with the cap between a retracted rest position in which the cap can include the carrier and associated operating levers, and a deployed position in which the operating levers are accessible by opening the cap from the outside, pivotally.
  • Vor incidents; differently designed control units can be arranged on the support or on the protective cap.
  • Electronic components or component are arranged in individual, small boxes, which are arranged in the area above the set of hydraulic valves, in a space which is protected from the outside of a housing, to which at least one removable cap belongs.
  • the present invention has the object to overcome the above-mentioned disadvantages and to provide an improved control system for cranes.
  • a basic object of the invention is It thus provides a compact control system in which associated electronic component boxes and associated cable guides for maintenance and troubleshooting purposes are easily accessible.
  • An additional object is to provide a control system for which mounting and testing of at least some electronic component boxes can be performed in addition to the ordinary manufacturing line, ie in a separate step before the final test of the crane as a whole.
  • the system shown in the drawings belongs as a whole with 1 designated frame, which has the task to carry several small electronic component boxes 2, 3.
  • the system further comprises two protective caps, of which a first with 4 and a second with 5 are designated.
  • the frame 1 has two laterally spaced side pieces 6, which are connected to each other via a cross piece 7.
  • This crosspiece 7 is mounted on two posts 8, which pass down into a designated as a whole with 9 bracket of the kind that has as a task to protect operating lever.
  • the system shown is indeed mounted on top of a set of hydraulic valves, not shown, the valves belonging to the hydraulic system of the crane and being influenced by hand in the space inside the bracket 9 operating lever. These operating levers are also not shown in the drawings.
  • any cables between the various boxes 2, 3 have not been shown on the drawings for clarity.
  • Characteristic of the invention is that at least some electronic component boxes, namely the boxes designated 2, are provided on a detachable, separate carrier 10, which is folded between a folded against the frame 1 use position (see Figure 2), in which the cap 4 the Carrier includes and the boxes, and a folded away from the frame position for maintenance purposes (see Fig. 5) is pivotable.
  • the carrier 10 consists of a substantially rectangular plate with two angled, stiffening side flanges 11, which in turn are connected by joints 12 to the bracket.
  • the bracket 9 is formed of two parallel legs 9 'and one front piece 9 ", on each of the legs 9' there is attached an ear 13 with a hole for the hinge 12. This hinge can be disassembled and made of a simple bolt with associated bolt Mother by removing the two hinge pin of the corresponding holes in the ears 13 and the side flanges 11, thus the carrier 10 can be removed from the bracket 9.
  • one or more electronic component boxes 2 are mounted on each of the two opposite sides of the carrier plate 10.
  • the support plate 10 is pivotally with advantage over an angle of at least 90 ° between the folded position shown in FIG. 2 and a folded-out position shown in FIG. 5.
  • the support plate 10 In the folded position, the support plate 10 is located in a vertical plane in which it is held by suitable means, e.g. Screws (not shown), which are tightened in seats 14 in the post 8.
  • suitable means e.g. Screws (not shown), which are tightened in seats 14 in the post 8.
  • Angled end portions 15 are made on the ears 13 to hold the support plate in the deployed end position and against which lower edges on the side flanges 11 can rest.
  • the support plate 10 is not shown in its lower end position, but in a horisontalen intermediate position from which the support plate can be pivoted downwards at about 10 ° -20 ° before the side flanges in contact with the bent-out end portions 15 of the ears come.
  • the first, front cap 4 is held in the mounted state by means of suitable coupling means 16, for example, tensioning hooks or rubber bands. At its lower ends, the cap 4 on outstanding portions 4 ', which cover the main part of the two legs 9' of the bracket 9. On the legs cuffs 17 are mounted, in which the ends of the protruding portions 4 'of the cap are inserted for fixing the cap. In a front wall of the cap 4, an opening 18 is taken out, in which the end walls of two electronic component boxes 2 are exposed. Removing the cap 4 is carried out by the simple measure to release the coupling means 16 and remove the cap from the sleeves 17.
  • suitable coupling means 16 for example, tensioning hooks or rubber bands.
  • the rear, second cap 5 is detachably connected to the frame 1, e.g. over a screw connection.
  • the component boxes designated 3 are provided in the example on a common, vertical support plate 18, which are suspended between the side pieces 6 of the frame. Depending on the length of these side pieces 6, a plurality of sets of catches and support plates can be successively mounted in the space between the side pieces.
  • the support plate 18 is releasably disposed to allow easy removal of the box set 3, e.g. for maintenance or testing purposes.
  • one or more sets of electronic component boxes can be assembled in at least one separate unit besides the usual manufacturing line for the crane. All the work in connection with the assembly and functional testing of the boxes can therefore be carried out with the boxes easily accessible and independent of the time pressure prevailing in the manufacturing line for the cranes. Furthermore, occurring maintenance after the use of the crane is largely facilitated.
  • the support plate 10 for the electronic component boxes 2 in the manner described is hinged, thus the boxes on both the front side and the back of the support plate are easily accessible, even in the event that the support plate remains on the bracket or the frame , If extensive maintenance is required, it is possible to release the carrier plate from the bracket and replace the entire component box unit with a new unit.
  • the rear unit of component boxes 3 will continue to be easily accessible after the front support plate 10 has been pivoted to its unfolded position. Also, the rear component box unit may be removed from the frame when extensive maintenance is required.
  • control components e.g. pneumatically operated components
