Abstract

In a curveless rail system for the rope-hauled carriage of a static inclined lift, two U-sections 1 form the running rails; the webs of the U-sections are bored at the same pitch in the longitudinal direction. Box-shaped frames 2, consisting of two U-sections bored at the same pitch in the longitudinal direction and of cross beams welded to the U-sections, are bolted at any point to the running rails 1 at the spacing distance. Attachment frames serve to attach further running-rail pairs 1; central frames are placed between one and the same running-rail pair 1. The rail construction is supported on foundations 5 via a single fixed bearing 3 and any number of movable bearings 4. All connections to be made between the elements 1 to 5 of the rail system upon assembly of the same are bolted. The rail system constructed according to the modular construction principle is flexurally and torsionally rigid, is suitable, among other things, for self projection and assembly, and can be adapted within wide limits to possible locations on a slope: To bridge a span of excessive length, the central frames are placed closer. The largely freely selectable angle of inclination can in the meantime be changed positively or negatively. Different gauges are possible. Short to medium-length inclined lifts are equipped with a rope winch; longer inclined lifts are given a revolving rope drive. <IMAGE>

The invention relates to a curved rail arrangement for the a rope-drawn carriage of a stationary inclined elevator.

Stationary inclined lifts serve both people and Load transport, are used on slopes of all kinds, you Tilt angle is adapted to the slope angle. With a Inclined elevator can be, for example, an incline that is difficult to walk on Bridge terrain. An inclined elevator can also be used as an alternative to Serve climbing stairs, e.g. from the lower boathouse or from the garage to the house, or as a goods and passenger lift Eg terrace houses, where he then has several stops needs. In industrial use, for example, you need it as Inspection lift for pipes at power plants, dams, as Feeder lift in underground tunnels or the like.

Stationary inclined lifts are particularly suitable for the transport of It is important for wheelchair users, but not the stairs without outside help can overcome. They can therefore be used for retrofitting, if e.g. in train stations or other public buildings of any kind not when planning for the transport of disabled people is adequately thought, since it is right on the edge of a Have the stairs built.

Curveless rail arrangements for stationary inclined lifts are in numerous embodiments are known. It is mostly around pure welded constructions, mostly one-offs, which in Individual project planning are adapted to a special requirement and in the course of the required assembly work on the slope be welded together; the establishment of such Inclined elevator according to the prior art is therefore an expensive one Purchase. There are also embodiments in which individual elements of the rail arrangement screwed during assembly be, cf. e.g. the US-Z: Elevator World, August 1986, p.44 to 52, especially the illustrations on page 46.

The GB 615 789 (Fig. 1 and 8 to 11) is a curve-free Rail arrangement for a mobile inclined elevator (for construction purposes) known whose rails are made up of several pairs of Can assemble fixed-length angle profiles. The angle profiles are, like the rungs of a ladder, firmly connected to each other by pipes connected, apparently welded. Successive Track pairs are detachably joined with lead frames, apparently screwed to the length of the rail assembly Adapt conditions at the construction site. The lead frames consist of two plates that are fixed to the frame via two pipes are put together. No other framework is provided; to the Frames do not attack any supports.

The invention has for its object one in a modular system Modular, bending and torsion-resistant rail arrangement for to create stationary inclined lifts, the elements of which are wide Limits can be adapted to possible slopes; the necessary Assembly work should be easy, i.e. without required Have welding work carried out by two assembly workers.

• zwischen den die Laufschienen bildenden ersten U-Profilen und den jeweils zugehörigen Rahmen,
• zwischen den Rahmen und den jeweils zugehörigen Auflagern und
• zwischen den Auflagern und den jeweils zugehörigen Fundamenten, lösbare Verbindungen sind.

To achieve this object, the following elements are provided in the curved rail arrangement according to the invention:

• two first U-profiles, each forming a running rail, arranged in mirror image, the two legs of which are facing away from one another and the web of which is in each case drilled in the longitudinal direction with uniform division,
• a plurality of frames which determine the track width of the two running rails and which are arranged between the two first U-profiles and each consist of two second U-profiles arranged in mirror image, the two legs of which are turned towards one another, the two webs of which are provided with holes of the same pitch in the longitudinal direction, rest on the respective web of the first U-profiles and are firmly connected to each other by at least two cross bars,
• Support, consisting of a fixed bearing, which rotatably engages one of the frames, and at least one floating bearing, which engages one of the frames and allows its longitudinal displacement, the supports being supported along a predetermined inclination line on an associated foundation, and the connections
• between the first U-profiles forming the running rails and the respectively associated frame,
• between the frame and the associated supports and
• between the supports and the associated foundations, releasable connections.

In the invention, box-shaped frames between the Running rails set. Both the U-profiles forming the running rails as well as the U-profiles of the frames have on their webs Holes in the longitudinal direction with the same pitch to each other are offset. In the holes aligned with each other, the Parts releasably connected together. The so-called central frames are on their U-profiles three holes and can be spaced apart can be placed anywhere between the tracks. Between the U-profiles of the frames are preferably two cross bars and welded to them; tubes are preferably used as cross bars.

Successive foundations are carried along on the slope Possibility set equal spans on which the Rail construction is supported. The foundations can be made steel-reinforced concrete can be poured, it is also suitable Steel structures or the like. With the usual span set foundations will be two or three consecutive Leave the holes on the running rails frameless.

To support the rail construction on the foundations Support provided, which is essentially a single There is a welded part, this is the console. It is a single one Fixed bearing provided on a cross member of one of the frames rotates, which attacks with the console, for example, a U-bracket is connected. The fixed bearing on the slope is preferably at the bottom arranged; if the condition of the subsurface is so does not allow, but it can also be anywhere else provide. Any number of floating bearings can be arranged each on opposite sides on the lower Thus attack the legs of the U-profiles of the frame so that they can be pushed slight longitudinal displacements of the rail construction as a result Allow thermal expansion or load, and on the console are rotatably received. The console of the floating bearing will again screwed onto a foundation.

In the invention, different welding parts are therefore used as elements provided, these are the frames and the consoles of the fixed bearing and the floating camp; these parts are prefabricated in the factory and at Assembly releasably connected to the associated elements, so that the construction site does not require any welding work.

All detachable connections are preferably screw connections.

In an advantageous development of the invention, the second U profiles the frame is chosen a standard size smaller than that First U-profiles forming the running rails. The running tracks and the Frames are screwed to the middle of their webs; This creates one step between the upper and lower legs of the U-profiles. In this stage, the console engages with one on each floating bearing track width crossbar and gives the rail assembly Lateral guidance and additional rigidity.

A further increase in stiffness can be achieved with the invention reach if the holes of the same pitch on the webs of the Running tracks forming the first U-profiles and on the second U-profiles the frame in the longitudinal direction in two parallel rows are set.

In the simplest version, the rail system consists of a short one Inclined elevator from a single pair of rails with inserted Frame and has two foundations for a fixed bearing and a floating bearing. The rail arrangement consisting of a single pair of running rails According to the invention, only a central frame is required as the frame.

With a medium-long inclined elevator up to about 40 m in length several pairs of running tracks lined up. Every track has a certain fixed length, preferably about 6 m. To the Row of running rails are so-called connection frames provided the protrusion at the ends of the runners equalize the first U-profiles. The U profiles of Lead frames preferably have four holes, of which the middle two to each other in the longitudinal direction with double Overhang are offset and the two end pairs of holes again have the usual division. So the lead frames are twice as long as the central frame; Furthermore they are the same as the central frame. The range with which the Foundations are set, preferably the fixed length of the Adjusted rails so that each pair of rails has an associated one Foundation is preserved. If necessary, two consecutive To set foundations with an overly long span because on impassable Terrain, for example, a wide ditch has to be bridged, then you can put the frames closer between the rails, if necessary in immediate consequence without any boring, which the Rail arrangement gives additional rigidity.

The short and medium-length inclined lifts are with a commercial double rope winch including motor, transmission gear and Brake equipped in a special frame between the Running rails are screwed. Preferably the winch arranged above the top foundation and thus closes the Track system from above. Basically, it can also be used any other free space between the runners arrange, the two pull cables are then on the upper cross bar of the top final central frame with rollers.

Long inclined lifts can make more sense in the invention Limits can be any length. You will be using a revolving pull rope equipped, preferably at one end of the rail system above, a drive wheel wraps around, has a deflection wheel at the other end, being a common tensioning device for tightening the pull rope worries in the empty strand. Preserved inclined lifts with a rotating cable drive preferably wider than winch-operated inclined lifts Frame, so a correspondingly wider gauge that it enables the carriage with its platform to be wider and longer to train. Long inclined lifts with rotating cable drives operated at a higher driving speed than winch-driven Inclined lifts, for which it is appropriate, the running rails forming first U-profiles by one or two standard sizes choose; the second U-profiles of the frames can remain unchanged.

In the invention, the angle of inclination of the rail arrangement can be adapt to a gradient angle that changes in between by using a Pair of rails is bent with a large radius; the same is also possible on the U-profiles of the frames. The change of Tilt angle can be positive or negative.

All inclined lifts are equipped with the usual safety devices provided and receive a control device for starting the required stops.

The invention thus represents a modular system for the curvilinear rail system of a stationary inclined elevator because of its flexibility for own project planning and installation by the client is suitable and therefore opposite known systems a very inexpensive alternative shows.

According to FIG. 1 , a curvilinear inclined elevator with its running rails 1 is erected along an incline line N which extends in a straight line at an inclination angle α on a falling terrain (not shown in detail); the angle of inclination α or α 'of line N can be adapted within wide limits to the corresponding slope. If possible, the foundations 5 are placed on the slope at regular intervals of the span W, on which the rail system of the inclined elevator is supported by supports 3,4; the foundations 5 can be cast from concrete, steel structures or the like can also be used. The lowest support 3 in the direction of inclination is designed as a fixed bearing, all other supports 4 are floating bearings. On the inclined lift, a commercially available double cable winch, integrated with motor, transmission gear and brake, is placed between the running rails 1 and screwed to them, cf. the top view shown at the bottom right in FIG. 1, which uses two ropes to pull up or lower the carriage not shown in FIG. 1.

The two rails 1 for the carriage run in a straight line parallel to one another at a distance of their fixed track width S. The structure of the rail construction is shown in detail in FIGS. 2 and 3 :

Accordingly, the two running rails are made according to Figure 2c and d of two parallel, symmetrically arranged first U-profiles 1, in cross section according to Figure 3 each consisting of two legs 1 _1, which are connected via a web 1 ₂ to the U-profile 1 . The two legs 1 ₁ of each U-section 1 to face each other in a lateral outward direction. Each track has the fixed length L ₁ and its web 1 ₂ is provided with two parallel rows of holes of the same pitch T in the longitudinal direction. At the end of each running rail 1, a certain projection U is provided for the associated hole.

Between the first two U-profiles 1, which form the running rails, box-shaped frames, designated overall by 2, are inserted at regular intervals and screwed to the first U-profiles 1. Each frame 2 also consists of two parallel, mirror-image arranged second U-profiles 2 _{1 of} short length L ₂ , the two legs 2 _{11 of which point} towards one another in the lateral direction. The height of the webs 2 _{11 of} the second U-profiles 2 ₁ is chosen to be a standard dimension shorter than the height of the webs 1 _{1 of} the first U-profiles 1; the webs 1 ₂ and 2 _{11 of} both U-profiles 1 and 2 ₁ are screwed together with half-round screws, so that the step designated Δh in FIG. 3 between the upper and lower legs 1 ₁ and 2 _{11 of} the first 1 and second U-profiles 2 ₁ arises. Between the two U-profiles 2 _{1 of} the frame 2, two tubes 2 ₂ defining the track width S of the running rails 1 are inserted symmetrically offset in the longitudinal direction and welded to form the frame with the two legs 2 _{11 of} the second U-profile 2 ₁ .

There are two types of frames, namely those shown in Fig. 2a Central frame 2 'and the connecting frame 2' 'shown in Fig.2b:

A central frame 2 'has two U-profiles 2 ₁ of length L _2' according to FIG. According to FIGS. 2c and d, the central frames 2 'are each to be set in the central region of each pair of running rails 1 and, as shown in FIG. 3d, can be offset by two 2T or three divisions 3T in the longitudinal direction of the running rails 1. A central frame 2 'must also be set at the end of the lower running rails 1, on which the fixed bearing 3 engages, as shown on the left in FIG. 2D.

On a lead frame 2 '' the protrusion U is to the Ends of the rails 1 balanced; there are two in the longitudinal direction Rows with four holes each, of which the middle both are set at a distance of 2U from each other and the two Edge pairs have the usual division T and at the end again Have protrusion U. The lead frame 2 '' are according to Fig.2c and d to be placed at the ends of a pair of rails 1 if a connecting rail 1 should follow.

In Figure 4 , the engagement of the wheels 7 _{1 of} the carriage 7 in the rails 1 is shown. The treads of the wheels 7 ₁ are adapted to the inclination of the inner legs 1 _{1 of} the running rails 1; the wheels 7 ₁ engage with play in the cavity between the legs 1 _{1 of} the first U-profiles 1 and roll on their lower legs 1 ₁ .

The rail construction shown in FIGS. 2 and 3 is supported on the foundations 5 with supports 3 and 4, respectively. The structure of the individual fixed bearing 3 is shown in FIG . 5 :

The fixed bearing 3 consists essentially of a one-piece, generally designated 3 ₁ console, which has a base plate 3 ₁₁ with two parallel arms 3 ₁₂ fixedly attached at its ends. Each arm 3 ₁₂ has a receptacle for the tube 2 _{2 of} one of the frames 2, which is open at the top in a semicircle, and a fixed cross piece 3 ₁₃ on one side. The base plate 3 _{11 together} with arms 3 ₁₂ with cross pieces 3 ₁₃ are arranged symmetrically to one another and welded to the one-piece bracket 3 _{1 of} the fixed bearing 3.

The bottom pair of rails 1 in the downward direction is closed at the bottom with a central frame 2 ', the lower cross member 2 _{2 of} which is inserted into the open-top receptacle on the arms 3 _{12 of} the console 3 ₁ and with a pair of U-shaped brackets 3 ₂ with the cross pieces 3 fixed to the console _{13 is} screwed. Of the tube 2 engages around ₂ and bolted to the cross-piece 3 ₁₃ U-bracket 3 ₂ forms with the console 3 _1, so to speak, a rotary joint. The console 3 ₁ is screwed to the foundation 5, in which the corresponding threaded shafts are firmly received, for example cast in.

6 shows the structure of one of the several floating bearings 4: Each floating bearing 4 also has a one-piece bracket, designated overall by 4 ₁ , consisting of a third U-profile 4 ₁₁ , in which parallel arms 4 _{12 are} firmly accommodated on both sides inside. On both arms 4 ₁₂ open receptacles for a cross tube 4 _{13 are} attached above. U-profile 4 ₁₁ , arms 4 ₁₂ and cross tube 4 ₁₃ are arranged symmetrically to one another and welded together to form a one-piece bracket 4 ₁ . The length of the cross tube 4 ₁₃ corresponds to the track width S.

The console 4 _{1 of} the floating bearing 4 is in turn screwed to the associated foundation 5. On both sides of the cross tube 4 ₁₃ , angles 4 ₃ engage the lower legs 2 _{11 of} the U profiles 2 _{1 of} the frame 2, which in turn are screwed to the cross tube 4 _{13 of} the bracket 4 ₁ with U-shaped brackets 4 ₂ . In the screwed state, the lower legs 2 _{11 of} the U profiles 2 ₁ rest against the cross tube 4 _{13 of} the console 4 ₁ , so that the cross tube 4 ₁₃ with its two ends in the step formed between the rails 1 and the second U profiles 21 Δh (see Fig. 3) engages and supports the rails 1 in the lateral direction. The angles 4 ₃ form with the lower legs 2 _{11 of} the U-profiles, so to speak, a thrust joint, thus allowing slight longitudinal displacements on the rail construction due to thermal expansion or load, and are rotatably received on the bracket-fixed cross tube 4 ₁₃ via the brackets 4 ₂ .
