Background

The present invention relates to a device for fastening the end of a hoisting line to a hoisting apparatus.

It is previously known to use a steel wire rope as a hoisting line for a hoisting device. For fastening the steel cable to the hoisting device, wedge shaped bags and rope tighteners are for example commonly used. The solution in question is very suitable for use with steel wire ropes, but for ropes comprising other materials this solution has proved to be disadvantageous.

The object of the solution presented herein is to develop a fastening method for a hoisting line that allows the material of the hoisting line to be chosen more freely than before for use.

Disclosure of Invention

The above object is achieved by a hoisting device according to the invention, which is characterized in that the hoisting device comprises a main body, a hoisting rope and a rope drum, as well as a hoisting member, which rope drum is arranged in connection with the main body, to which drum a first end of the hoisting rope is fastened and around which drum the hoisting rope is wound, which hoisting member is raised and lowered by the hoisting rope, and in that the hoisting device further comprises a fastening device for a second end of the hoisting rope, having at least one portion, around which a spiral groove is formed, and in that a section adjacent to the second end of the hoisting rope is received to surround said portion, and in that the hoisting device is provided with a fastening device which locks the second end of the hoisting rope to the fastening device, preventing the second end from being pulled out of the fastening device. By such a solution it is possible to fasten the hoisting rope by friction, so that the material of the hoisting rope can be chosen more freely to fit.

Detailed Description

With reference to fig. 1, a fastening device for fastening a synthetic rope to a hoisting device, the main components of which comprise a body 1 of the hoisting device, a hoisting rope 2, a rope drum 3 arranged in connection with the body, a hoisting member 4, a fastening means 5 of a second end of the hoisting rope 2, and a fastening device 6 for locking the second end of the rope to the fastening means 5, at least one portion of the fastening device 5 having a helical groove formed therein around said portion and in which a portion adjacent to the second end of the hoisting rope 2 is received so as to surround said portion. As the material of the fastening device 5, for example, aluminum can be used, so that it is not necessary to coat or paint it to prevent corrosion. Alternatively, painted steel may be used.

As shown in fig. 1, in this embodiment said fastening means 5 of the second end of the hoisting line 2 is fastened to e.g. the body 1 of the hoisting device. The fastening advantageously enables a detachable and rotatable coupling. The detachable fastening makes it possible to change the position of the fastening means 5 if necessary, and the rotatable fastening allows the fastening means to rotate around the fastening point, for example if the load to be lifted should swing.

When the fastening means 5 are fastened to the body 1 of the hoisting device, it is necessary to fasten at least one first sheave 7 to the hoisting member 4, said first sheave 7 receiving the hoisting rope 2 from the rope drum 3. In the embodiment of fig. 1, the hoisting line 2 extends between the hoisting member 4 and the body member 1 a number of times, whereby there is one second pulley 8 arranged in connection with the body member. In this example, the fastening means is fastened on the same shaft 9 as the second pulley 8.

In the example of fig. 1, said part of the fastening means 5 forms a closed loop such that it surrounds a fastening point provided at a central part of the fastening means 5, by means of which fastening point the fastening means 5 is fastened to the lifting device. Alternatively, the ring may be open at certain positions. The ring may be angled, as shown in fig. 1, or at least partially circular.

The fastening means 5 may be made of cast iron or steel and the hoisting rope 2 may be a synthetic hoisting rope, for example

A rope therein

Fig. 2 shows a second embodiment of the lifting device. The embodiment of fig. 2 largely corresponds to the embodiment of fig. 1, and therefore in the following the embodiment of fig. 2 will be mainly explained by disclosing the differences between these embodiments. In the present example, the fastened fastening means 5 and the lifting members 4 are connected together on a separate shaft 10. Unlike the example, the fastening means 5 may alternatively be fastened on the same shaft 12 simultaneously with the pulley 11, or on the shaft 12 instead of the pulley 11.

Fig. 3a to 3c show a first preferred embodiment of a fastening device, which can be used in the embodiment of fig. 1 and 2. The parts indicated in fig. 3a to 3c have formed closed square rings with rounded corners. In the present example, the fastening means 5 have fastening locations 13 formed inside its ring, which fastening points are formed by openings 14, which can be screwed onto the end of the shaft, or through which, for example, fastening bolts can be screwed. Alternatively, the fastening points 13 of the fastening means 5 may be arranged on the outside of the ring.

Referring to fig. 3a and 3b, the fastening point 13 of the fastening means 5 is advantageously positioned such that the point between the first and second end 2-2 of the hoisting rope 2, at which the hoisting rope 2 is received in the slot 15 of the hoisting means 5, is located on the same vertical line 16 as the fastening point 13 of the fastening means 5. In this way, torque generation on the fastening device 5 is avoided. In the slot 15 of the fastening device 5, this point is located near the first end 15-1 of the slot 15, as shown in fig. 3 c.

As shown in fig. 3 a-3 c, in a preferred embodiment the loop is at least partly arranged around a groove 15 receiving the second end 2-2 of the hoisting line. The groove 15 may also substantially surround the entire ring. Providing multiple loops of grooves in the portion is advantageous because the multiple loops of grooves increase the friction between the hoisting line and the fastening means, thereby ensuring that sufficient fastening is maintained. In addition, the surface of the groove 15 may be treated to increase friction. Adding friction to the grooves 15 may be achieved, for example, by coating the grooves 15 or by forming protrusions in the grooves 15 at the manufacturing stage of the grooves 15, thereby enhancing friction.

The groove 15 is substantially round, or at least rounded, and the shape of the groove is substantially semi-circular, and the dimensions of the groove closely match the outer diameter of the hoisting rope 2 used. Thus, the groove 15 supports the hoisting rope 2 from the side when subjected to tension, so that the hoisting rope does not collapse, in particular when it is subjected to tensile strength. When advantageously provided, the slot 15 extends beyond the receiving point of the hoisting rope 2, so that the hoisting rope 2 can be moved along the slot 15 without touching the acute angle, as will be explained below in connection with the swinging movement.

Fig. 4a to 4b show a second preferred embodiment of a fastening device, which can be used in the embodiment of fig. 1 and 2. The embodiment of fig. 4a and 4b largely corresponds to the embodiment of fig. 3a to 3c, and therefore in the following the embodiment of fig. 4a and 4b will be mainly explained by disclosing the differences between these embodiments. The embodiment of fig. 4a and 4b comprises fastening means 5' the part of which enclosed by the groove 15 forms a circular closed loop. In the embodiment described, the groove 15 surrounds substantially the entire ring.

Still referring to fig. 3a to 3c and 4a and 4b, the hoisting line 2 is received on the fastening means from near the first end 15-1 of the slot, after which the hoisting line 2 is at least partly arranged in the slot 15. Finally, the second end 2-2 of the hoisting rope 2 is fastened to the fastening means by means of a fastening device.

Fig. 5 shows by way of example a fastening device. The fastening arrangement in question comprises fastening means, such as a bolt 17, and a knot 18, such as a splayed knot, tied to the second end 2-2 of the hoisting line 2. In the fastening arrangement in question, the hoisting rope 2 is slightly open on the part at the side of the groove and a bolt 17 is fitted through the resulting clearance, which bolt 17 is fastened to the fastening means by turning it, so that the second end 2-2 of the hoisting rope 2 is locked in position. In this case, the knot prevents the end of the rope, which is slightly open, from untwisting/unraveling.

Unlike fig. 5, the fastening device may have a hole through which the second end 2-2 of the hoisting rope 2 can be passed, after which a knot is tied at the second end 2-2 of the hoisting rope 2 to prevent the pulling out of the hoisting rope 2. In this case, the screw shown in fig. 5 is not needed in the fastening device, but instead it is the knot and hole that holds the second end of the rope in place in the fastening means.

In the above, by way of example and with reference to the drawings, it is disclosed that the hoisting line is looped around a part of the fastening means. However, this is only an example of a preferred embodiment, which allows to achieve a compact fastening device that fits, for example, to fasten coaxially with a pulley on a pulley axle extension. Alternatively, it is also possible to form the portion as a straight rod.

Unlike the example in the figures, the fastening arrangement may comprise threading the second end 2-2 of the hoisting rope 2 thereunder and tensioning after threading thereunder, whereby the portion of the hoisting rope threaded thereunder is tensioned between the hoisting rope 2 and the fastening means 5. The fastening can be further improved by tying a knot at the end of the hoisting rope 2 threaded underneath, thus preventing the hoisting rope from being pulled out when the hoisting rope 2 is in tension.

Still differently from the figures, the fastening arrangement may comprise a plate and fastening means by which the second end 2-2 of the hoisting rope 2 is tensioned between the plate and the fastening means 5. The fastening device can be further improved by knotting the second end 2-2 of the hoisting rope 2 to prevent the hoisting rope 2 from being pulled out when the hoisting rope 2 is in tension.

In the different embodiments, in terms of the oscillation of the load, it can be noted that the oscillation of the load from the vertical direction to any direction can be considered structurally. For example, in the direction according to fig. 1, the problem is a sideways swinging movement, which is taken into account by providing the fastening means with a fastening point 13, around which the fastening means can be rotated. When the swinging movement is transverse with respect to the above-mentioned lateral movement, i.e. swinging in the direction of the pin axis of the fastening point 13, this can be taken into account by lengthening the rope groove below the lower edge of the fastening means. In fact, all the cases of swinging motion and diagonal pulling can be divided into the above two directions of motion.

It will be obvious to a person skilled in the art that as the technology advances, the basic idea of the invention may be implemented in many different ways. The invention and its embodiments are thus not limited to the examples described above, but may vary within the scope of the claims.
