Definitions
- the invention relates to a steering post for a work machine, in particular for a timber crane or a crane for parcelled goods, comprising a steering plat ⁇ form mounted on the frame of the machine and a seat connected to the steering platform by means of a seat leg.
- Such steering posts are currently very common for instance in timber vehicles, where a timber crane mounted on the vehicle is steered from a steering post attached to the crane post, for example.
- the steering post generally comprises a steering platform equipped with a ladder and a seat equipped with slide guides and connected to the steering platform by means of a seat leg.
- the crane operator controls the hydraulic direc ⁇ tional valve from the seat by means of hand levers and foot pedals that are mounted on the steering platform by means of bearings or are attached directly to the valve.
- the seat can be adjusted to a suitable position so that workers of different sizes can work in an ergonomically correct working position.
- the aforesaid fact is essen ⁇ tial also from the point of view of industrial safety, for example.
- the seat can be moved horizontally forwards and backwards by means of the aforementioned slide guides. Distance adjustment by means of the slide guides is a simple and effective solution, therefore this adjustment has not generally caused any practical problems.
- What has been problematic in previous solu ⁇ tions is how to adjust the height of the seat. Height adjustment has conventionally been achieved slowly and with difficulty by moving the screw fastening of the seat leg in relation to the steering platform by means of tools. In some constructions adjustment has been so difficult that in practice it has not been done at all.
- a further problem in the previous solutions has been the fact that lateral blows directed towards the seat may break the seat construction and may thus lead to an interruption of work and in the worst case even to injuries.
- the seat may be exposed to blows for example when the crane pivots about its vertical axis and there is not enough space left for the seat. Lack of space may be due to, for example, too long logs which are put into the load space of the vehicle and against which the seat strikes when the crane pivots.
- the object of the invention is to provide a steering post by means of which the disadvantages of the prior art may be eliminated.
- This has been achieved by means of the steering post according to the invention which is characterized in that a tubular member is connected to the steering platform in a substantially vertical position and that the seat leg and the tubular member are fitted at least partly within each other and secured in their place by means of bearings so that the seat leg can move vertically in relation to the tubular member and that the seat leg may pivot about its longi- tudinal axis by the action of a torque reaching or exceeding a given magnitude by turning the bearings a corresponding degree in their fastening.
- the primary advantage of the invention is its simplicity, i.e. easy adjustability of both the distance and the height of the seat can be achieved by means of a simple construction.
- a further advantage is that by means of the invention it is possible to create a con ⁇ struction which in a way will yield when lateral blows are directed towards the seat. Due to this yielding con- struction, the problems of the crane breaking down are minimized and the risk of the operator being hurt is reduced. As a result of the aforesaid simple construc ⁇ tion the costs of production remain low, so the intro ⁇ duction of the invention becomes profitable.
- Figure 1 is a schematic side view of a steering post according to the invention, in connection with a timber crane,
- Figure 2 is a representation of a cross-section of one of the details of the solution shown in Fig. 1,
- Figure 3 is a representation of one of the details of Fig. 2 on a larger scale
- Figure 4 is a top view of the construction shown in Fig. 2,
- FIG 5 is a schematic side view of the steering post according to the invention
- Figure 6 is an exploded view of the steering post according to the invention.
- FIG 1 is a schematic representation of the steering post according to the invention, in connection with a work machine, for example a timber crane.
- the crane is denoted generally by the reference numeral 1.
- a steering platform 3 is mounted on the crane frame 2, for instance on the crane post. If necessary, the steering platform 3 may be equipped with, for example, a ladder 4.
- the reference numeral 5 denotes in Figure l a seat which is connected to the steering platform 3 by means of slide guides 6, a sliding frame 7 and a seat leg 8.
- the slide guides 6 and the sliding frame appear distinctly in Figures 2 and 6.
- the adjustment of the position of the seat either forwards or backwards is achieved by means of the slide guides 6.
- the seat may also be tipped into a transport position by turning the seat around the axle journal 10.
- the axle journal 10 shows distinctly in Figures 2, 5 and 6, for example.
- a tubular member 9 is connected to the steering platform 3 in a substantially vertical position.
- the seat leg 8 is fitted coaxially inside the tubular member 9 and secured in its place by means of bearings 11, so that the seat leg 8 and naturally at the same time also the seat 5 attached to it may move vertically in rela ⁇ tion to the bearings 11 connected to the tubular member 9, and that the seat leg 8 may pivot about its longi ⁇ tudinal axis 12 by the action of a torque reaching or exceeding a given magnitude by turning the bearings with it around its longitudinal axis 12.
- the seat leg 8 and the tubular member 9 are made of tubes with different kinds of cross-section, and the inner surface of the bearings 11 is shaped to fit the outer surface of the cross-section of the seat leg 8, and the outer surface correspondingly to fit the inner surface of the cross-section of the tubular member .
- the seat leg 8 can be made of a tube with the cross- sectional shape of a polygon, for example a tube with a square cross-section, and the tubular member 9 can be made of a tube with a substantially round cross-section.
- the solution described above shows clearly in Figures 4 and 6.
- the bearings 11 are connected to the tubular member 9 by means of a compressive force parallel to the longitudinal or symmetric axis 12 of the tubular member.
- This compressive force is adjusted to be so great that the forces caused by the normal rotating motion of the crane cannot make the seat turn.
- the compressive force directed at the bearings 11 is achieved by means of a tightening flange 13 and screws 14. When the screws 14 are being tightened, the bearings 11 are pressed against the tubular member 9 as described above.
- the pressure points are shown in Figure 3 denoted by the reference numerals 15 and 16.
- the height adjustment of the seat is achieved in the example of the Figures by means of a gas spring 17.
- the gas spring 17 is attached from one end to the tubular member 9 by means of a fixing element 18, and from another end to the seat leg 8 by means of nuts 19.
- the seat leg 8 is secured to the tubular member 9 by means of the bearings 11 as stated above.
- the seat leg 8 may naturally be slideably secured to the tubular member 9 also from the lower end, if necessary.
- Figure 2 provides a schematic representation of this type of support denoted by the reference numeral 20.
- the height of the seat may be adjusted by opening the valve of the gas spring by means of a rocking bar 21, whereupon the leg will be pushed upwards by the gas spring. It is essential to note that the bearings 11 are not tightened against the seat leg 8, but that the leg can slide quite freely in the tubular member. The adjustment downwards may be done in a corres ⁇ ponding manner, i.e. by opening the valve and by pressing against the force of the gas spring.
- the pivoting of the seat about the vertical axis which in a normal situation impedes the controlling of the crane is prevented by means of the dissimilar cross-sectional surfaces of the tubular member and the seat leg, and by means of the bearings which match these surfaces, as shown in Figure 4 and above.
- the seat leg 8 cannot pivot in relation to the tubular member, since the bearings 11 connected to the tubular member prevent such a rotating motion. If a lateral force, for example a lateral blow, directed at the seat and simultaneously at the seat leg is so great that it produces a torque about the axis 12 which exceeds the force resisting rotation produced by the compression brought about in the points 15 and 16, the seat leg 8 will pivot about in the tubular member at the same time turning the bearings 11 with it inside the tubular member. Thus the construction will yield in certain situations, which guarantees that the components do not break down.
- the magnitude of the force which, if exceeded, causes the bearings to slide in relation to the tubular member can be controlled by adjusting the tightening of the screws 14.
- the invention is by no means restricted to the use of a gas spring, for instead of the gas spring some other control device, e.g. a hydraulic cylinder, a pneumatic cylinder, or a screw etc., can be used to achieve the fastening of the height adjustment and possibly also the compensation of the weight of the seat to facilitate the height adjustment.
- the height of the bearings can also be increased, thus rendering it unnecessary to support the seat leg from its lower end etc.
- the compressive force on the bearings can be achieved also by means of spring-like elements.
- the invention restricted to the seat leg being fitted inside the tubular member as in the example of the Figures, but the construction can be reversed, i.e. the tubular member can be fitted inside the seat leg.
