Definitions
- the invention relates to a chassis of a lifting device, in particular with a laterally projecting boom, according to the preamble of claim 1.
- a trolley for trolleys is known, the two Has impellers, each on an inner horizontal side surface of a support in the longitudinal direction downward open hollow profile rail and are rotatably mounted on an impeller.
- the wheel carrier is designed that it extends down through the opening of the rail and a Forms the connection element on which the load to be lifted hangs.
- the connector is further provided with a horizontal cross member, on which two by a vertical Axis rotatable support rollers are arranged, each on an outer vertical side surface with a component perpendicular to the supporting force of a Support the impeller.
- the undercarriage is driven by one on the outer surface of the lower one Drive roller attached to the flange.
- Such a chassis is only suitable for rails that are open to the sides are formed and have a web so that support rollers on both sides of the Bridges can be brought to the plant.
- a downward open, however otherwise closed, hollow-profile rail without a web inside is a such chassis not applicable, especially since the wheels are within move the rail on both sides above the opening and therefore not on one U-shaped chassis frames arranged outside the rail can be supported.
- the object of the invention is a movable in a hollow profile rail Design the chassis so that the wheels without lifting off the rail experience a load balancing, so that even with rigid suspension of the rail Smooth running is achieved and heavy wear is prevented.
- the invention provides that the impeller and the Connection element are supported on one another in a joint that the least supports a support roller inside the rail and that at least one in Connection element mounted roller on at least one outer tread of the Rail with a force that supports a component against the direction of force an impeller.
- a chassis designed in this way enables Horizontal forces are effective in the side surfaces of the hollow profile rail initiate, so that there is no destruction or to rigidly suspended rails no heavy wear and no twisting of the chassis and / or the Rail is coming. Jamming of the undercarriage is largely avoided, so that a smooth running of the trolleys even when using a one vertical axis of the swiveling boom is achieved, the changing vertical forces generated.
- the joint is a universal joint that is large Angular range is articulated.
- a more stable embodiment results if the at least one support roller on Connection element is rotatably supported in the upper region.
- a smoother running of the chassis is achieved in that the wheels in Direction of travel are arranged one behind the other.
- the treads are used to ensure self-centering chassis guidance the rail is arranged at an angle to each other and the running surfaces of the wheels are crowned educated.
- the smooth running of the chassis is ensured in particular by the fact that the gimbal-formed joint from a rigid with the connecting element connected ball head and a ball socket arranged on the impeller is formed.
- a simple adjustment or adjustment can be achieved in that the from below on a horizontal outer tread formed on the rail adjustable roller via an eccentric bearing in the direction of the rail can be adjusted below, leaving play between the roller and the rail, especially to compensate for rail tolerances. As a result, the after vertical forces directed above are safely guided into the rail.
- connection element is on both sides Rollers are arranged and that the rail on both sides horizontal outer Has treads for the rollers.
- a particularly stable undercarriage is obtained by having two in parallel rails arranged to each other on a rail a pair of bogies and a single running gear is provided on the other rail.
- Fig. 1 shows a view of a chassis 1 of a rail movable Lifting device.
- the chassis 1 has one behind the other and seen in the direction of travel in pairs parallel to each other arranged spherical wheels 2, which are arranged on both sides of a connecting element 3.
- spherical wheels 2 which are arranged on both sides of a connecting element 3.
- an arrangement with offset on both sides of the connecting element 3 impellers 2 arranged to one another are possible.
- support rollers 4 In the upper part of the Connection element 3 are seen in the direction of travel between the impellers 2 arranged support rollers 4 rotatably.
- the vertical axes of rotation 5 of the support rollers 4 are supported on the connecting element 3.
- In the embodiment is on each side of the Connection element 3 exactly one support roller 4 is provided.
- the support rollers 4 can also be arranged in front of and / or behind the wheels 2, wherein a pairwise arrangement transverse to the direction of travel is particularly useful has proven.
- a single large support roller 4 is also conceivable.
- the area of the connecting element is on both sides in a vertical plane revolving roller 6 provided.
- Fig. 2 shows a cross section through a chassis, which is inside one after open below hollow profile rail 7 is located.
- the rail 7 has a cold-rolled special profile, resulting in a low weight and good Strength and stiffness values can be achieved.
- the roll Wheels 2 on substantially horizontal inner treads 8, which are easy are arranged obliquely to each other and extend in the longitudinal direction of the rail.
- the two support rollers 4 are inside the rail 7 on at least one side surface 7a unrollable.
- the arrangement can be designed so that in the central position, that is in the absence of horizontal forces, there is a game. This way is included Occurrence of horizontal forces to be derived only one of the support rollers 4 one of the side walls 7a of the rail 7, introducing these forces into the Rail 7.
- Fig. 2 can also be seen that the connecting element for attaching a load protrudes from rail 1 below.
- a play-free, quasi “rigid" connection between chassis 1 and rail 7 is due to the eccentric bearing Guaranteed rollers 6 adjustable from below in the direction of the rail.
- the Adjustment of the rollers 6 takes place, for example, once after inserting the Running gear 1 in the rail leaving a game, e.g. of 1 mm; a Readjustment is possible at any time during operation.
- the Adjustment of the rollers 6 from below to a horizontal outer tread 15 of the rail 1, on which it is supported with a force that is a component has against the direction of force of the impeller 2.
- Fig. 3 shows a cross section through a formed from chassis 1 Complete undercarriage, for example a trolley of a suspension crane on which for example, a hoist (not shown) can be moved. It is essential with this Overall chassis that the connecting elements 3 of the on different rails arranged trolleys are rigidly connected to one another by a cross member 31, as shown in Fig. 4 in cross section. Such an overall chassis already shows very good running and load properties. Get a significant improvement one if you combine at least two pairs of trolleys 1. To do this the connecting elements 3 of the trolleys 1 arranged on different rails, which are at the same height as seen in the direction of travel, each by a Traverse connected together.
- the longitudinal direction expediently close the cross member 31 and the longitudinal direction of the rail each an angle of 90 °.
- a complete chassis consisting of four over cross members 31 rigid interconnected trolleys 1
- the boom 30 by a vertical To arrange the swivel axis pivotably. It has been shown that with this Arrangement when swiveling a load almost no vertical lowering of the Load takes place, so that by an operator with little effort The load can be swiveled into any position.
- Such 6 shows a hanging crane with trolley in a schematic representation.
- a stable running of the entire undercarriage can also be achieved with a Achieve three-point support by placing two parallel to each other Rails 7 on a rail 7 a pair of trolleys 1 and on the other Rail a single chassis 1 are arranged.
