Description

A material handling device or crane comprising a support frame with rail wheels
Background of the invention
The object of the invention is a material handling device or crane comprising a support frame with rail wheels according to the preamble of claim 1.
A material handling device comprising a support frame with rail wheels is known from the patent publication GB 1,086,917. The material handling device presented in this publication comprises a rail support frame for mounting the material handling device movably onto rails provided on a foundation, and an upper carriage provided with material handling means, which carriage is turnably mounted on the rail support frame. The rail support frame comprises a first and a second elongated rail unit provided with rail wheels, intended to be arranged in the direction of the rails and a first and a second elongated intermediate structure transversal to the first and second rail units, which transversal intermediate structure interconnects the first and the second elongated rail units and to which the upper carriage provided with the material handling means is turnably mounted. The first and second elongated rail units are connected to the transversal intermediate structure by means of a pivot joint such that the first and second elongated rail units can turn in a turning motion in relation to the transversal intermediate structure about a pivot axis which is essentially parallel to the rotation axes of the rail wheels of the first and second elongated rail units. The object of this solution is to enable contact between the rail wheels and the rails and, by means of this, sufficient support for the material handling device also in cases, where the rails are not parallel to each other, in other words, in a situation, where the rails, in at least part of the track, extend at different angles to the horizontal and thus, in the vertical direction, are located at different levels in at least one part of the track.
A problem in this prior art solution is that, due to the pivot joint solution for the rail support frame, which enables turning of the first and second elongated rail units in a turning motion in relation to the transversal intermediate structure, the material handling device is unstable and this is disadvantageous to the material handling or lifting activity. Brief description of the invention
The objective of the invention is to solve the aforementioned problems.
The objective of the invention is achieved by means of a material handling device or crane according to the independent claim 1.
Preferable embodiments of the invention are presented in the dependent claims.
The invention is based on the material handling device or crane (below "the material handling device") comprising turning motion inhibitor means, which can be switched into an inhibiting position in order to prevent the turning motion of the first elongated rail unit in relation to the transversal intermediate structure and which correspondingly can be switched into a releasing position in order to enable the turning motion of the first elongated rail unit in relation to the transversal intermediate structure.
The turning motion inhibitor means preferably, but not necessarily, comprises a hydraulic arrangement and/or a mechanical arrangement. The hydraulic and/or a mechanical arrangement can be switched into an inhibiting position in order to prevent the turning motion of the first elongated rail unit in relation to the transversal intermediate structure. Correspondingly, the hydraulic and/or mechanical arrangement can be switched into a releasing position in order to enable the turning motion of the first elongated rail unit in relation to the transversal intermediate structure.
Since the material handling device with a freely swaying pivot joint would be unstable during loading, the swaying of the pivot joint is prevented by, for example, plunger pistons of a hydraulic arrangement for the duration of loading i.e. material handling work, preferably, but not necessarily, automatically at the termination of a run, i.e. automatically after the termination of a movement of the material handling device along the rails. The hydraulic arrangement can be adapted to function such, that the plunger pistons by means of a pilot pressure are kept released and in contact during a run. As the pilot pressure is depleted, the locking valves in the plunger pistons preferably, but not necessarily, automatically close, thus preventing motion of the plunger pistons and swaying in the pivot joint.
In a preferable embodiment of the solution according to the invention, the rail support frame comprises a first leg structure between the first elongated rail unit and the transversal intermediate structure, and a second leg structure between the second elongated rail unit and the transversal intermediate structure. In this preferable embodiment, the first elongated rail unit is rigidly attached to the first leg structure and the second elongated rail unit is rigidly attached to the second leg structure. In this preferable embodiment, the first leg structure is connected by means of a pivot joint to the transversal intermediate structure such, that the first elongated rail unit together with the first leg structure can turn in a turning motion in relation to the transversal intermediate structure about such a pivot axis, which is essentially parallel to the rotation axes of the rail wheels of the first elongated rail unit. In this preferable embodiment, the second leg structure is turning- wise rigidly attached to the transversal intermediate structure such, that the second elongated rail unit together with the second leg structure cannot turn in a turning motion in relation to the transversal intermediate structure. In this preferable embodiment the turning motion inhibitor means are arranged in the area between the first leg structure and the transversal intermediate structure.
In a solution according to the invention the material handling device comprises a damping arrangement adapted to act as a chock absorber for the material handling device in said releasing position and to attenuate the turning motion of the first elongated rail unit in relation to the transversal intermediate structure, particularly when the material handling device is moving on the rails provided on the foundation, i.e. when the material handling device is being moved along the rails provided on the foundation.
List of Figures
Below, some preferable embodiments of the invention are described in more detail with reference to the appended Figures, of which Figure 1 shows a first preferable embodiment of the material handling device comprising a support frame with rail wheels,
Figure 2 shows the rail support frame of the material handling device with a support frame provided with rail wheels shown in Figure 1 ,
Figure 3 shows the rail support frame shown in Figure 2 from another angle of view.
Detailed description of the invention
The Figures show a material handling device comprising a support frame with rail wheels.
The material handling device comprises a rail support frame 1 for movably mounting the material handling device on rails provided on a foundation.
The material handling device additionally comprises an upper carriage 4 provided with material handling means 3, which upper carriage is turnably mounted on the rail support frame 1.
The rail support frame 1 comprises an elongated first rail unit 6a provided with rail wheels 5, intended to be arranged in the direction of the rails 2, and an elongated second rail unit 6b provided with rail wheels 5, intended to be arranged in the direction of the rails 2.
In the Figures, the rail wheels 5 are arranged in four bogie structures 7 turnably hinged to the first elongated rail unit 6a and to the second elongated rail unit 6b such, that the first elongated rail unit 6a comprises two bogie structures 7 and the second elongated rail unit 6b comprises two bogie structures 7, which are arranged in the area of the ends of the first elongated rail unit 6a and the second elongated rail unit 6b.
The rail support frame 1 additionally comprises an intermediate structure 8 transversal in relation to the first elongated rail unit 6a and the second elongated rail unit 6b, which transversal intermediate structure interconnects the first elongated rail unit 6a and the second elongated rail unit 6b, and to which intermediate structure the turnable upper carriage 4 provided with the material handling device 3 is turnably mounted.
The first elongated rail unit 6a is connected to the transversal intermediate structure 8 by means of a pivot joint 9 such, that the first elongated rail unit 6a can rum in a turning motion in relation to the transversal intermediate structure 8 about such a pivot axis 10, which is essentially parallel to the rotation axes 11 of the rail wheels 5.
Preferably, but not necessarily, only the first elongated rail unit 6a is connected to the transversal intermediate structure 8 by means of a pivot joint 9, so that only the first elongated rail unit 6a can turn in a turning motion in relation to the transversal intermediate structure 8 about such a pivot axis, which is essentially parallel to the rotation axes 11 of the rail wheels 5 of the first elongated rail unit 6a.
The material handling device comprises turning motion inhibitor means 12, which can be switched into an inhibiting position in order to prevent the turning motion of the first elongated rail unit 6a in relation to the transversal intermediate structure 8, and which correspondingly can be switched into a releasing position in order to enable the turning motion of the first elongated rail unit 6a in relation to the transversal intermediate structure 8.
The turning motion inhibitor means 12 preferably, but not necessarily, comprise a hydraulic arrangement (not shown in the Figures) and/or a mechanical arrangement (not shown in the Figures), which hydraulic and/or mechanical arrangement can be switched into an inhibiting position in order to prevent the turning motion of the first elongated rail unit 6a in relation to the transversal intermediate structure 8 and which hydraulic and/or mechanical arrangement correspondingly can be switched into a releasing position in order to enable the turning motion of the first elongated rail unit 6a in relation to the transversal intermediate structure 8.
The material handling device preferably, but not necessarily, additionally comprises a damping arrangement (not shown in the Figures), which, in said releasing position, is adapted to act as a damping arrangement for the material handling device, i.e. as a kind of shock absorber, and to damp the turning motion of the first elongated rail unit 6a in relation to the transversal intermediate structure 8, particularly when the material handling device is moving on the rails 2 provided on a foundation, i.e. when the material handling device is being moved along the rails 2 provided on a foundation.
In the material handling device shown in the Figures, the rail support frame 1 comprises a first leg structure 13a between the first elongated rail unit 6a and the transversal intermediate structure 8 and a second leg structure 13b between the second elongated rail unit 6b and the transversal intermediate structure 8. In the Figure, the first leg structure 13a is rigidly attached to the first elongated rail unit 6a and the second leg structure 13b is rigidly attached to the second elongated rail unit 6b. In the Figure, the first leg structure 13a is connected by means of a pivot joint 9 to the transversal intermediate structure 8 such, that the first elongated rail unit 6a together with the first leg structure 13a can turn in a turning motion in relation to the transversal intermediate structure 8 about such a pivot axis 10, which is essentially parallel to the rotation axes 11 of the rail wheels 5 of the first elongated rail unit 6a. In the Figure, the second leg structure 13b is rigidly attached to the transversal intermediate structure 8.
In the material handling device shown in the Figure, the turning motion inhibitor means 12 comprise a hydraulic arrangement. The hydraulic arrangement comprises hydraulic cylinders 14, which are arranged between the first leg structure 13a and the transversal intermediate structure 8. The hydraulic cylinders 14 can be controlled into an inhibiting position in order to prevent the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8, and into a releasing position in order to enable the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8.
The material handling device presented in the Figure can, in addition to the presented hydraulic arrangement or as an alternative to the presented hydraulic arrangement, comprise a mechanical arrangement (not shown in the Figures) for preventing the turning motion. In the case shown in the Figure, the mechanical arrangement would be arranged between the first leg structure 13a and the transversal intermediate structure 8. The mechanical arrangement, in a manner corresponding to the presented hydraulic arrangement, would be controllable into an inhibiting position for preventing the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8 and, correspondingly, into a releasing position for enabling the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8.
Contrary to the Figures 1 - 3, the first leg structure 13a can be rigidly attached to the transversal intermediate structure 8 and the second leg structure 13b can be rigidly attached to the transversal intermediate structure 8. In this case, the first elongated rail unit 6a would be connected by means of a pivot joint 9 to the first leg structure 13a such, that said first elongated rail unit 6a could turn in a turning motion in relation to the transversal intermediate structure 8 and the first leg structure 13a about such a pivot axis 10, which would be essentially parallel to the rotation axes 11 of the rail wheels 5 of said elongated rail unit 6. In this case, the second elongated rail unit 6a would be rigidly connected to the second leg structure 13b. In this case, the turning motion inhibitor means 12 would comprise a hydraulic arrangement of a corresponding kind as the one presented in Figures 1 - 3. In this case, the hydraulic arrangement thus could comprise hydraulic cylinders 14, which would be arranged between the first leg structure 13a and the first elongated rail unit 6a. In this case, the hydraulic cylinders 14 would be controllable into an inhibiting position for preventing the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8 and the first leg structure 13 a, and, correspondingly, into a releasing position for enabling the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8 and the first leg structure 13 a. In this case, the material handling device, in addition to said hydraulic arrangement or as an alternative to the hydraulic arrangement, could comprise a mechanical arrangement (not shown in the Figures) for preventing said turning motion. Said mechanical arrangement would be arranged between the first leg structure 13a and the first elongated rail unit 6a. Said mechanical arrangement would be controllable into an inhibiting position for preventing the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8 and the first leg structure 13 a, and, correspondingly, into a releasing position for enabling the turning of the first elongated rail unit 6a in a turning motion in relation to the transversal intermediate structure 8 and the first leg structure 13 a. In the arrangements according to the Figures, the hydraulic cylinders 14 preferably, but not necessarily, are adapted, in said releasing position, to act as a damping arrangement for the material handling device, i.e. as a kind of shock absorber and damp the turning motion of the first elongated rail unit 6a in relation to the transversal intermediate structure 8, particularly when the material handling device is moving on the rails 2 provided on a foundation.
The turning motion inhibitor means 12 preferably, but not necessarily, comprise an automatic switching arrangement, which functionally is connected to a control system (not shown in the Figures) for the propulsion of the material handling device, the task of said control system being to control the motion of the material handling device along the rails 2 under control of the operator of the material handling device. Said automatic switching arrangement preferably, but not necessarily, is adapted to act in such a way, that the swaying of the pivot joint 9, by means of, for instance, plunger pistons of the hydraulic arrangement, is automatically inhibited for the duration of the loading, i.e. the working of the material handling device, after termination of a run, i.e. automatically after cessation of the motion of the material handling device along the rails 2. The hydraulic arrangement can be adapted to act in such a way, that the plunger pistons, by means of a pilot pressure, are maintained released and in contact during a run. After depletion of the pilot pressure, locking valves in the plunger pistons will close, thus preventing movement of the plunger pistons and swaying in the pivot joint 9.
For a person skilled in the art, it is evident, that, along with advances in the art, the basic idea of the invention can be implemented in many different ways. Thus, the invention and its embodiments are not restricted to the examples described above, but they rather can vary within the scope of the claims.
