Description

Method and apparatus for aligning a crane
The invention relates to a method defined in the preamble of claim 1 and to an apparatus defined in the preamble of claim 4 for aligning a crane for the purpose of fastening the ends.
Background of the invention
According to known technique, the alignment of connecting plates to be attached to the ends of a crane girder casing is ensured by means of separate directional gantries running on rails. During the fastening of the connecting plates, the plates are first welded to the ends of girder casings that are positioned upside down. After the welding, mounting holes are drilled in the connecting plates for the purpose of fastening the ends. In order for the ends to be mutually parallel, the rows of mounting holes at each end of the casing must be aligned. The aforementioned directional gantries have been used for this purpose. The problem with the prior art arrangement is the large directional gantry system that runs on its own rails and that is expensive and bound to one place. Small subcontractors cannot usually acquire such a system either due to the space available or the price of the system. Furthermore, it is not worthwhile to move the system presently used for example closer to the place of assembly during the manufacture. Summary of the invention The purpose of the present invention is to eliminate the aforementioned drawbacks and to provide a new and advantageous arrangement for aligning the crane for the purpose of fastening the ends. The method according to the invention is characterized by what is disclosed in the characterizing portion of claim 1. The apparatus according to the invention is characterized by what is disclosed in the characterizing portion of claim 4. The other embodiments of the invention are characterized by what is disclosed in the other claims.
The invention provides the advantage that the crane can be aligned with a small and inexpensive apparatus which can be transported closer to the place of assembly of the crane at a very low cost, or which can be given to the subcontractor to be used for a predetermined period. Brief description of the drawings

Figure 7 is a top view of a guide plate used in the alignment.
Detailed description of the invention
In order to illustrate the invention, an apparatus implementing the method according to the invention will be described first. The actual apparatus used in the alignment is very simple and has a light construction. The apparatus comprises a pair of identical guide plates 5. There are different guides plates for cranes of different types and sizes. Figures 2, 3, 6 and 7 show a guide plate used in the alignment of a double-casing crane, whereas Figures 4 and 5 show a guide plate used in the alignment of a single-casing crane. The guide plate is a plate having exact measurements and two accurate parallel grooves 8 and 9 that are cut on the plate transverse to it, one of the grooves being provided for a directional binocular 6 and the other one for a target plate 7. The guide plate also comprises openings 10 for guide pins and actual guide holes 11 for drilling the mounting holes of the connecting plates 2. The guide holes 10 and 11 are provided with hard metal rings that are glued to the guide holes so that they would last as long as possible. The position of the guide holes 11 with respect to each other and to the grooves 8 and 9 is very exact. Each guide plate has an identical pair. The guide plate further comprises spiral openings 12 for fastening hoist brackets when the guide plate is lifted from its place and lowered back. In a guide plate of a double-casing crane, the grooves 8 and 9 are positioned adjacent to each other, slightly spaced apart, substantially in the middle of the guide plate and mutually symmetrically on both sides of the axis of the guide plate, whereas one end of a guide plate of a single-casing crane comprises a groove 8 for the directional binocular 6 and the other end correspondingly comprises a groove 9 for the target plate 7. The grooves 8 and 9 are then positioned in such a way that their mutual horizontal distance is greater than the width of the crane casing. These grooves are also positioned mutually symmetrically on each side of the axis of the guide plate. The target plate 7 that is fastened to the second groove 9 of the first guide plate is provided with a vertical line at which the directional binocular 6 provided in the groove 8 of the second guide plate is directed during the alignment process. The guide plates are also provided with a container which can hold both the guide plates and other auxiliary instruments required in the alignment. The guide plates may thus be easily sent to the subcontractor that performs the assembly of the crane in the factory or near the site of use of the crane.
Figure 1 is a side view of one end of a crane girder casing 1. Connecting plates 2 are fastened by means of welding when the casing is upside down on supporting beams 3. The connecting plates are usually separate plates, but it is possible that the bottom plate of the casing extends all through the casing and thus forms at the end of the casing a structure that corresponds to the connecting plate. The term 'connecting plate' refers in this connection to both arrangements. Support elements 4 that can be seen between the supporting beams and the casings in Figure 2 are used in the positioning of the casings. The connecting plates 2 shown in the figures are bent into an angle, when viewed from the side, but the plates may also have some other form.
Figures 2 and 3 show the alignment arrangement of a double-casing crane. In such a crane, the hollow girders must first be placed at the same point, as accurately as possible, on their supporting beams in the longitudinal direction. Similarly, the casings are positioned to be mutually parallel by means of auxiliary bars that are used at the ends of the casings, that extend between the casings, and that are equal in length. When the casings are parallel and situated at the same point, the connecting plates are welded to the ends of the casings.
After the connecting plates have been fastened, the guide plates 5 are hoisted on the connecting plates 2 in such a way that the first plate of the pair of guide plates is hoisted on the connecting plates of one end of the casing, and the other guide plate of the same pair is hoisted on the connecting plates of the other end of the casing. The guide plates are positioned in such a way that the longitudinal direction of the guide plates is transverse to the longitudinal direction of the casings, and that the guide plates extend substantially over the parts of the connecting plates on which the mounting holes for the ends are drilled. It is essential that the guide plates are arranged in such a way that they are positioned at the same point in the transverse direction of the casing. The guide plates can be accurately placed at the same point by fastening them on a level with the lateral edge of the connecting plate, for example in Figures 2 and 3 the left edge of the guide plate extends to the right from the level of the left edge of the left connecting plate. The guide plates 5 shown in the figures have exactly the same length as the width of the finished casing structure at the connecting plates, wherefore the guide plates extend from the left edge of the left connecting plate to the right edge of the right connecting plate. In the single-casing arrangement shown in Figures 4 and 5, the guide plate 5 is longer than the connecting plate below it. The lateral alignment can then be performed by first centring the connecting plate as accurately as possible and by aligning the axes of the connecting plate and the guide plate as accurately as possible.
When the guide plates are positioned at the same point, they are accurately aligned by means of the directional binocular 6 and the target plate 7. The vertical line of the grid provided in the binocular is aligned on the vertical line provided in the target plate by rotating the plate around its centre in the horizontal plane according to the arrows 13. During the alignment, the guide plates of each end must be rotated in turn so that the ends can be brought to right angles with respect to the longitudinal line of the casing. When the guide plates are parallel, they are fastened to the connecting plates or to some other fixed place by means of screw clamps. After this, small-diameter openings are drilled in the connecting plates for the purpose of guide pins, under the direction of the guide pin openings 10 of the guide plate. When these openings are made, the guide pins are placed in the openings whereafter the screw clamps can be removed. The actual mounting holes for the ends are then drilled in the connecting plates under the direction of the guide holes 11 of the guide plate. When all the holes have been drilled, the guide plates can be removed and placed in the container together with the auxiliary instruments. The ends can now be fastened with screws in the normal way.
It is clear for a person skilled in the art that the different embodiments of the invention are not restricted to what is described above by way of example, but they may vary within the scope of the appended claims.
