- DE 944 330 discloses a double rail trolley in which the hoist or the cable drum is arranged between the chassis members or the cross member to form their connection.
- this trolley leads a suspension shaft for two driven wheels through the cable drum, at one end of a head carrier is arranged, which carries a further impeller, which serves to guide the cat.
- the Overall height of the cat above the rails of the crane girders is not greater than the height the chassis carrier itself.
- the chosen construction of the hoist is consuming and the cat sensitive to distortion and tilt under load.
- the object of the invention is therefore a twin rail trolley with 3-point storage provide, whose height above the rails of the crane girder is as low as possible and at the same time good accessibility to the essential components of the Hoist ensures.
- the track distance of the cat should not be increased and load the load as evenly as possible.
- the weight may be Counterweights reduced and the torsional load of the cross member are minimized.
- the two-rail trolleys have a specific Minimum height above the level of the rails on the crane girders, if possible is kept low, so that the overall height of the crane can be minimized. This is necessary, inter alia, for weight, space and cost reasons.
- first chassis carrier with the second chassis carrier by means of the cross member connected approximately centrally and also has the first chassis support a larger Longitudinal extent than the second chassis carrier has and protrudes while the hoist in Moving direction beyond the second chassis carrier, so the accessibility you are the essential components of the hoist in a simple manner possible.
- the second chassis support can be made very short and access to the hoist is not hindered.
- the second chassis carrier can be configured with only one impeller. This depends however, from the planned operating conditions and the payload to be transported. The permissible load of the impeller and its attachment to the chassis girder may not exceed Operation should not be exceeded.
- At least one impeller is drivable and at the bottom of the rail at least one pair of friction rollers cooperating with the driven impeller is arranged, which has a setting of the distance from one another to the bottom of the Rail are adjustable, a slipping z. B. by lifting the driven impeller can be prevented.
- the two friction rollers of each pair of friction rollers are symmetrical to the axis of rotation of the respective driven impeller below the impeller are arranged.
- each pair of friction rollers is above a Support rod set to the respective chassis carrier.
- the support rod can in this case two pivotable about a common axis two-armed lever, wherein at a free end of each lever a Friction roller is rotatably mounted.
- a spring-loaded pressure mechanism which consists of a the two free ends of the lever interconnecting screw and one on the Screw attachable and consists of a nut tensionable compression spring.
- each pair of friction rollers is in a preferred embodiment at a transverse to the direction of travel on the first chassis support shaft pivoted.
- FIGS 1 and 2 show an inventive top running twin rail trolley 300, which comprises a first chassis carrier 301 and a second chassis carrier 302, which are each connected centrally by means of a cross member 303.
- a Hoist 304 arranged in the direction of travel V of Two rail trolley 300 in front of and behind and laterally on the cross member 103.
- the first chassis carrier 301 has two wheels 313 and 315, of which the impeller 313 with a drive 314 for moving the trolley in the direction of travel V on the rails 312 of the crane girder 311 is provided.
- the axes the wheels 313 and 315 are arranged one behind the other in the direction of travel V and have a large distance C, so that the wheels 313, 315 in the region of At the beginning and end of the crane girder 311 are stored.
- the illustrated embodiment of the Twin trolley 300 according to the invention in which the second chassis carrier 302 has two wheels 316 and 317, which via a rocker 320 on the cross member 303rd attached, creating a statically determined 3-point storage of the trolley 300th is reached, so that it is possible in contrast to the conceivable rigid arrangement, compensate for different high contact points of the wheels 316/317.
- the rocker is shown in detail in FIG. It includes a traverse 321 with two wheel axles 322 for the wheels 316 and 317, which via a pendulum axis 323 with the second chassis carrier 302 is connected.
- the pendulum axis 323 is an in Longitudinal direction of the cross member 303 aligned and thus horizontal axis pivotable.
- the axes of the two wheels 316 and 317 thus have in contrast to those of Wheels 313, 315 a smaller distance D to each other.
- the second Chassis support has in the longitudinal direction just such an extent that the Arrangement of the wheels 316 and 317 in the direction of travel V one behind the other is possible.
- the first chassis carrier 301 thus has a larger one in the longitudinal or travel direction V. Longitudinal extent than the second chassis carrier 302. Thus hinders the second Fahrwerkzan 302 access to the hoist 304 not because this laterally in Moving direction V beyond this.
- the lateral arrangement of the lifting mechanism 304 on the cross member 303 is such that the overall height H of the two-rail trolley above the rails 312 is not increased becomes.
- the upper edge of the hoist 304 so does not protrude above the chassis beams 301 and 302 out.
- All parts of the invention Twin rail trolley arranged so that it does not exceed the top of the Chassis support projecting upwards (see Fig. 2).
- the cable drum 305 of the hoist 304 is by means of frame parts 306 and 307 with the Cross member 303 connected and rotatably supported between them.
- the main drive components such as cable drum bearing, drive, gearbox and electrical control. Due to the positioning of the hoist 304 off-center on Cross member 303, d. H. near the second landing gear carrier 302 facing Crane beam 311 is the access to these components maintenance and repair friendly possible without scaffolding. It can be seen, in particular in Fig. 2, that access to the Frame part 307 of the hoist 104 not by the second chassis support 302th is restricted.
- the cross member 303 also serves to receive or fix a top bottle 308 and a Seilendbefest only 309 of a rope 318 of the hoist 304.
- the rope 318 is according to a simple Einscherung of the Seilendbefest only 309 via a Load hook 310, the upper bottle 306 and the load hook 310 on the einrillige cable drum 305 led.
- the cable drum 305 and the cable end attachment 309 of Hubtechniks 304 on one side and the upper bottle 308 on the opposite side of the cross member 303 - seen in the direction of travel V - arranged.
- the load hook 310 travels in a small, indicated by the arrow W. Area around the center K of the track width S of the trolley 300 between his lowest and highest lift position. This requires a favorable distribution of Load on the twin rail trolley.
- the second embodiment of Twin trolley 400 is the second chassis support 402 with a further reduced end plate 402 formed, which by the use of only an impeller 416 is enabled. This can be done at relatively small payloads cheaper and more structurally simple, namely, if the allowable load of End plate 402, the allowable compressive stress under the impeller 416 not in operation exceeds.
- the trained as a friction roller pair support roller pair 319 is on the chassis carrier 301 provided, pivotally mounted under the chassis support and supported by means of Spring preload on the bottom 326 of the top plate 325 of the crane girder 311 from, so that slippage of the driven impeller 313 is prevented.
- the support roller pair 319 is attached to a downwardly extending arm 327 of the Chassis carrier 301 arranged and comprises two levers 328, the scissors over a pin 330 are strigkbar. At one end of the lever are the individual Rollers 329 rotatably mounted and at the other, opposite free end the levers 328 are connected to each other via a pressing mechanism 331. Of the Pressing mechanism 331 causes a pivoting of the lever 328 relative to such each other, that the distance of the rollers 329 to each other and thus their contact pressure is adjusted against the bottom 326 of the top plate 325 of the crane girder 311. hereby can the impeller 313 with the desired contact force on or against the rail 312nd be pulled to prevent slippage.
- the pressure mechanism 331 consists of one of the two free ends of the lever 328 connecting screw 332, on which a coil-shaped Spring 333 is fitted, and a nut 334 to the spring 333 in a suitable manner adjust or tension.
