Definitions

  • ABSTRACT A plumbor inclination-setting device for an apparasash a esltilfiaamaehine ne P at r or t liliefhaving a member which is tiltable in relation to the horizontal plane, said member being regulated from an operating position located at a distance from the tiltable member, comprises a housing attachable to the tiltable member. In the housing there is a level illuminated by a lamp or mirror and a means for magnification and reproduction of the level, so that convenient viewing of the enlarged image of this with the naked eye is permitted from the operating position.
  • the housing has an aiming device movable in relation to and fixable to the housing, which aiming device is arranged for such advance setting that when the image of the level bubble is centered in the level housing, the tiltable member adopts a predetermined direction in both the horizontal and the vertical plane.
  • the present invention refers to a plumbor inclination-setting device which can be used in many different types of apparatuses such as drilling machines, cranes, platforms etc.
  • One object of the invention is to obtain a plumbor inclination-setting device which has great accuracy and reliability, is simple to handle and use, has a simple construction and is easily adopted to different types of apparatuses being adjustable primarily as concerns their inclination relative to the horizontal plane.
  • a plumbor inclination-setting device for an apparatus comprising a member which is tiltable in the vertical plane such as a drilling machine, crane, platform, etcetera, the inclination of said tiltable member in relation to the horizontal plane being regulated from an operating position located at a distance from the tiltable member, substantially characterized by a housing attachable to the tiltable member, which housing has at least one level illuminated by a lamp, mirror or the like and means for magnification and reproduction of the level. so that convenient viewing of the enlarged image of this with the naked eye is permitted from the operating position.
  • the housing is rotatably and/or displaceably attached to the tiltable member or to a bar parallel with the longitudinal axis thereof.
  • a graduate scale is preferably used for setting of the housing in relation to the tiltable member and there is in many applications also a second graduate scale in a plane at right angles to the first one.
  • the part of the housing provided with means for reproduction of the level is preferably rotatable in relation to the part containing the level, so that the enlarged image of the level always is visible from the operating position.
  • the housing has an aiming device movable in relation to and fixable to the housing, which aiming device is arranged for such advance setting that when the image of the level bubble is centered in the level housing the tiltable member, e.g. the feed beam, adopts a predetermined direction in both the horizontal and the vertical plane.
  • the tiltable member e.g. the feed beam
  • FIG. 1 is a sectional view of a device according to the invention.
  • FIG. 2 is a perspective view of a drilling machine provided with a device according to FIG. 1.
  • FIG. 3 is a section of modified embodiment.
  • FIG. 4 is a view of a device provided with an associated direction-finding instrument.
  • FIG. 5 is a plan view of an aiming device provided with aligning means for the direction-finding instrument.
  • FIGS. 6-8 illustrate different steps when using the device and instrument combination according to FIGS. 4 and 5.
  • a housing 11 contains one or more levels 1, Le, transparent, liquid-filled containers of tube or box type with a gas bubble or metal droplet which is/are illuminated or mirrored from below, from above or from the side counted from the marking made in the level which indicates the position of the bubble when the level is in the horizontal or other specific position.
  • suitable lenses 2 or other system the bubble is reflected and the position marking appropriately enlarged, e.g. 10 times, on an inclined plane or an inclined mirror 3 and focussing screen 4.
  • the housing with its contents is provided with a means 6 permitting setting of a predetermined angle in one plane such as an inclination angle relative to the horizontal plane, and setting of another angle in a plane at right angles thereto such as a certain direction in the horizontal plane.
  • the housing is attached to for instance the feed beam of a drilling machine 12 of the kind illustrated in FIG. 2.
  • the lamp 7 necessary for the illumination needs only small batteries as its power source.
  • the degree of magnification is decided by the demands for viewability from the drillers operating position.
  • the driller In order for the driller to be able to check the inclination of the drilling platform after commencement of drilling the upper part 11a of the device with mirror/focussing screen or inclined plane is rotatable. Normally the device is mounted at eye level on the drilling platform.
  • the device as shown in FIG. 2 is movable along a bar 8 parallel with the drilling rod 13.
  • a device of the kind described below enabling the longitudinal axis of the instrument to be rapidly adjusted so as to become parallel with the drilling rod may also be used.
  • the instrument can be attached directly to the drilling machine. This is preferred when the machine is handheld or when the feed beam, as frequently happens, is curved.
  • the device is dust-protected and preferably vibrationfree, and is suspended and protected from blows and jolts by the protective casing 11.
  • the focusing screen 4 is surrounded by a screen or protective hood 11a for sunbeams, so that viewing of the enlarged image of the level in sunny weather is facilitated.
  • the device can be mounted pivotably, possibly with a motor, on a pole (not shown), so that the device itself works as a plummet. Between the device and the pole is an adjustable and graduated means which allows angular setting of the drilling unit around the horizon.” The aiming of the horizontal direction of the drill holes is regulated by observation of the built-in compass 5. The device will rotate around its axis when the feed beam is reset. At the same time, the upper part of the casing 11 can be rotated either manually or mechanically, possibly with a motor, so that the level is visible in all positions from the operating position. The combined level and pendula arrangement provides accurate control of both direction and angle to the horizontal plane.
  • the compass housing can be rotatable from outside.
  • the device is used in the following manner: To begin with, the graduated scale 6 is set at the wanted angle of inclination, whereafter the feed beam 9 (FIG. 2) is aligned in plane with the aid of the compass or other aligning device of the kind described below. The angular relationship of the feed beam 9 is then adjusted with the aid of the level 1. If the device does not adopt the vertical position automatically this is adjusted with the built-in electric motor 30.
  • One or two angular prisms are mounted with one axis at right angles to the drilling rod and feed beam, so that if the device is turned around the said axis a plane parallel with the drilling rod is defined.
  • the prism or prisms are then in their turn individually rotatable around axes parallel with the former and can by means of wires and worm gears be maneuvered by the driller from his operating position.
  • the image in the prisms is enlarged and reflected in the same manner as in the previously described apparatus.
  • This equipment includes staking poles, possibly illuminated, such as by lighted neon tubes therewithin, provided with a graduated setting facility.
  • the two staking poles are first erected along the upper edge of the wanted cutting and with the same inclination as this.
  • the first described inclination-setting instrument is set at the wanted angle of inclination, whereafter the drilling machine and drilling platform are maneuvered partly so that the level is zeroed and partly so that the staking poles are visible in line with the respective focussing screens.
  • the desired number of degrees appropriately in the same direction as the tunnel has is set on the compass and the angle of inclination of the tunnel on the inclination-setting instrument, whereupon the drilling machine and feed beam are maneuvered until the wanted position is reached, i.e., when the image of the bubble is centered on the screen 4.
  • the housing can be combined with a direction-finding instrument of the kind shown in FIGS. 4 and 5.
  • the housing 21 is then united with a tiltable member 22, e.g. a feed beam on a drilling machine of the kind shown in FIG. 2 via a second housing 23, here designated angle housing.
  • This angle housing features a universal joint (not shown) or the like and a graduated scale 6 for setting of the predetermined inclination of the tiltable member in the vertical plane.
  • a pivotable or rotatable aiming device Carried on the housing 21 is a pivotable or rotatable aiming device with a holder 24 and four aligning means 25.
  • the aligning means 25 are located in the corners of a square or rectangle. Each and every one of these can with the aid of two other aligning means allow aligning towards either a point in the direction of the tiltable member, e.g., the feed beam, or a point in a direction opposite thereto.
  • the holder 24 is fixable in relation to the housing 21 by means of a brake device 26.
  • the aiming device 24, 25 is flxable to the angle housing via a lock pin 27, which can snap into a hole 28.
  • the lock pin 27 can be detained but can be activated when so desired, whereupon it can enter the said hole.
  • the direction-finding instrument is used in the following manner:
  • the wanted inclination e.g. in the ratio 3:1 of the tiltable member in relation to the horizontal plane is set on the graduated scale 6.
  • the angle housing 23 is then disengaged.
  • the tiltable member can now be set from the operating position with the correct inclination and roughly the correct direction in the horizontal plane.
  • the correct inclination is obtained by centering the level bubble.
  • the operator returns to the operating position and maneuvers the tiltable member, e.g. the feed beam. until the image of the level bubble is centered.
  • angle housing 23 When the angle housing 23 is made to move to the position in which the lock pin 27 enters the hole 28 it can theoretically be said to move along the generatrix of a cone, the cone angle of which corresponds to the angle of inclination in relation to the horizontal plane of the tiltable member, e.g. the feed beam.
  • Exact transmission of the directional change which must be carried out by the tiltable member in order for it to adopt the wanted predetermined direction and inclination thereafter takes place in conjunction with the centering of the level bubble in that the tiltable member, e.g. the feed beam 22 is then imparted a motion back along the generatrix of a corresponding cone.
  • the movement of the tiltable member need naturally not follow the said generatrix. The movement can thus take place stagewise in different directions or for example follow a chord between a point on the said generatrix which corresponds to the initial position and another point on the generatrix which corresponds to the predeterminal final position.
  • the direction of the said chord is indicated to the operator by the position of the level bubble in relation to the centering point of the level bubble.
  • a direction-finding instrument allows very great accuracy for setting in both the horizontal and the vertical plane. Theoretically, an accuracy of l/600 can thus be obtained.
  • the hole 28 can be superseded by several corresponding holes.
  • the angle housing can be locked together in an arbitrary position in relation to the aiming device.
  • the device has been described in connection with a drilling machine but it is evident to the man of art that it can find many other applications where it is of importance that one member shall take a predetermined angle relative to the ground or a second member. Further the aiming instrument described will facilitate directioning of the one member in a plane at right angles to the plane in which the first mentioned predetermined angle is set.
  • a plumb or inclination-setting device for an apparatus comprising a member which is tiltable in a vertical plane such as a drilling machine, crane, platform or the like, the inclination of said tiltable member in relation to the horizontal plane being regulated from an operating position located at a distance from said tiltable member, characterized by a housing, means for mounting said housing upon said tiltable member so that said housing is rotatable about a first axis perpendicular to said vertical plane, a level carried by said housing, means for illuminating said level, and means for projecting a magnified image of said level so that said magnified image of said level may be viewed with the naked eye from the operating position.
