Definitions

  • the present invention relates to a device for covering a cargo space, referred to below as a container, with a cover which is to cover a top opening of the container.
  • the device in the document comprises two lifting arms arranged pivotally on two opposing side walls of a container. Running between the lifting arms is an axle on which a cover is rolled up. Two pulling belts are also coiled up to the axle.
  • the lifting arms are made to turn by means of hydraulic cylinders, one for each lifting arm, affixed to the side walls. When the hydraulic cylinders are activated, the lifting arms make a circular movement over the container and the cover is unrolled at the same time as the pulling belts are reeled in and vice versa.
  • the device described has several disadvantages. The arrangement with hydraulic cylinders affixed to the side walls means that these are impossible to open, for example for tipping the goods.
  • the object of the present invention is to remedy the aforementioned problems and provide a device for non-manual covering of a container.
  • Fig. 1 shows a view in perspective of the device mounted on an elongated container with open end doors
  • Fig. 2 shows a view obliquely from the side of a part of the device according to Fig. 1 and
  • Fig. 3 shows the movement pattern diagrammatically for a lifting arm forming part of the device and how this is changed in length during covering of the container.
  • the device which is shown in the drawings has the general reference number 10. It is intended to be fixed to a cargo space 12, henceforth referred to as a container, which is formed by two first opposing lateral limiting surfaces 1 and 22, which form the front end and consist of a pair of rear opening doors respectively, a pair of second opposing lateral limiting surfaces 2, 3, which form the long sides of the container, and a bottom, which is not shown.
  • a frame 4 running round on all sides is arranged in the upper part of the container and follows the upper edges of the container 12 and defines the opening 5 which is to be covered by the cover, which can consist of a covering canvas, net or similar.
  • the device comprises two arms 14, referred to below as lifting arms, one end of which is affixed by turning links 6, Fig. 2 and Fig. 3, pivotally to the upper part of the two first opposing lateral limiting surfaces 1, 22, more precisely to a horizontal cross-beam 24 which is included as a part of the said frame 4 and forms the upper edge at the front and rear ends.
  • the lifting arms are formed so that they can be varied in length, in the embodiment shown as a telescopic arm with an inner beam 16, which is affixed pivotally by the turning link 6 to the container, and an outer extension beam 18, Fig. 2.
  • a little way from the turning link 6 of the lifting arm is a first control device 20 in the form of a control shoulder or control pin attached to the outer extension beam 18 at right angles to the longitudinal direction of the lifting arm 14.
  • the container is intended for loose goods for carriage by lorry and is openable via the doors 22 in the rear end of the container for tipping goods.
  • the horizontal cross-beam 24 is fixed to the upper edge at the rear end, in which case the cross-beam 24, in addition to carrying the lifting arm 14, can also be provided with an element for locking the doors 22 in the closed position.
  • a second control device 38 Arranged closely adjacent to the lifting arms 14 is a second control device 38.
  • This has the form of a guide rail, referred to below as a ramp, mounted on a second transverse beam 7 a little way inside the frame 4, parallel to the rear transverse beam 24. More precisely, the guide rail/ramp 38 is mounted in a curve symmetrically over the turning link 6 and a somewhat ahead of this.
  • the ramp 38 begins a way in from the longitudinal side walls 2, 3 of the container and extends at first as a first inclined plane 38a at a certain angle ⁇ in relation to the cross-beam 7. The ramp then changes to a horizontal part 38b, to be completed by a downward part 38c in the form of second inclined plane of an equally great but opposing inclination to the first part 38a.
  • the beam 7, ramp 38 and lifting arm 14 are arranged in such a manner in relation to one another that the first control device/control pin 20 is in contact with the beam and ramp during a part of the covering movement, which will be described in greater
  • a boom 26 is arranged rotatably between the free ends of the extension parts 18 of the lifting arms 14 parallel to the long sides 2, 3.
  • a driving means 28 in the embodiment shown a hydraulic motor on the extension part 18 of the rear lifting arm and connected via conduits 30 to a suitable hydraulic pump, which is not shown.
  • Line drums 32 are arranged fixedly at both ends of the boom.
  • the line drums 32 have on the whole/substantially the same circumference as the boom 26.
  • Steel lines 34 are arranged between the line drums 32 and the corner 8 with the long side of the frame 4 which forms the upper part for the long side 3.
  • the lines 34 are suitably attached to the container 12 via some elastic means such as rubber straps, springs or similar to reduce variations in the tension of the lines.
  • Other pulling devices capable of winding on the drums 32 are also conceivable instead of steel lines, for example very strong belts, cables, chains etc.
  • the covering canvas 36 is suitably attached to the container via elastic fixing devices.
  • the device functions as follows, reference being made to Fig. 3 in which the movement pattern of the lifting arms and the position of the control pin 20 and the boom 26 during the movement are shown diagrammatically.
  • the container is open upwards, the covering canvas 36 is rolled up on the boom 26, the lines 34 are maximally uncoiled and the lifting arms 14 like the lines 34 are aligned essentially parallel to the upper edge of the container, which is defined by the frame 4.
  • the control pins 20 rest on the respective beam 7, and the lifting arms are nearly horizontal and parallel to the beam 7.
  • the positions of the control pin and boom when the covering canvas is completely rolled up on the boom have been marked by 20° and 26° in Fig. 3.
  • the hydraulic motor 28 is activated, which begins to rotate, so that the boom 26, which is connected to the motor, rotates in an anticlockwise direction with reference to Fig. 1.
  • the lines 34 then start to be coiled on the line drums 32 at the same time as the covering canvas 36 is unrolled. Coiling of the lines 34 on the line drums leads to the lines pulling in the telescopic lifting arms 14, which in the initial phase are shortened without being turned substantially in the turning link 6, due to the fact that the outer extension beam, with the control pins 20 sliding on the beam 7, is pulled inwards over the inner beam 16 in the direction of the turning link 6, on account of the fact that the lines in this phase run essentially parallel to the lifting arms, part I in Fig. 3.
  • the lifting arm 14 thereafter continues its turning movement, the control pin 20 and boom 26 moving in an arc III in Fig. 3, until its control pin comes into contact with the other inclined part 38c of the ramp, position 20'", or 26'" for the boom.
  • the lifting arm is extended due to the fact that the lines pull out the extension beams 18 at the same time as the control pin 20 slides against the sloping plane 38c and in the final phase against the beam 7, until the boom 26 has come out to the frame 4 over the long side 3, when the hydraulic motor 28 is stopped.
  • the position of the control pin when it meets the ramp again following its free circular movement has been designated 20'" and when it leaves the ramp has been designated 20 in Fig. 3, and the final position has been designated 20 v .
  • Corresponding positions for the boom have been designated 26'", 26TM and 26 v .
  • the movement pattern is symmetrical with the movement pattern during the lifting beam's upward movement.
  • the covering canvas 36 is rolled up on the boom 26 in an analogous manner to unrolling, the hydraulic motor 28 being rotated in the opposite direction, at which the covering canvas 36 functions as the pulling device instead of the lines 34.
  • the advantages of the present invention are many. Thanks to the telescopic design of the lifting arms 14 and due to the arrangement of the interacting control devices, i.e. the control pin 20 and ramp 38 and to a certain extent also the beam 7, the device 10 as a whole, and above all the turning link 6 of the lifting arms, can be confined to the upper part of the container and do not need to encroach on the lateral surfaces of the container, which also means inter alia that the part of the device 10 which is located in the area in front of the rear part of the container can in all respects be arranged above the doors 22. For this to be able to be achieved it is essential that the control pin 20 and the ramp 38, and in part also the beam 7, through interaction with the pulling devices, i.e.
  • the motor 28 and lines 34 on unrolling or the covering canvas 36 on rolling up provide initiation of the angle of inclination ⁇ , which is required for the arm to be able to be turned. If the angle of inclination is not sufficiently large, very great forces are required in the motor to be capable of lifting the arm. It would otherwise be necessary as in said SE 404 915 to move the turning point of the lifting arms down and/or move up the point of action of the turning means to bring about rotation of the arms.
  • the telescopic function results in further advantages. If the load has a height which exceeds the highest point of the boom during rotation, the boom will come into contact with the load and will "climb" on the load during rotation while the arms are being extended, in contrast to conventional devices with fixed arms. In addition, driving of the boom and not the lifting arms means that a more controlled movement is obtained, at the same time as pulling askew of the device is avoided if a lifting arm is obstructed.
  • the driving can also be effected for example by an electric motor.
  • the device limited to containers which open backwards, but can be adapted to a large number of different containers which are open upwards.
