Abstract

Lifting mechanism, wherein a wagon can be moved in a guided manner on a linkage, in particular comprising rails and/or a toothed rod, wherein the movement can be carried out up to a first height, wherein a primary conductor system is laid along the direction of movement up to a second height, with the wagon comprising a drive and a secondary coil via which the drive can be supplied with electrical power in a non-contacting manner, wherein the secondary coil is inductively coupled to the primary conductor system.

Description

Bont

Technical field

The present invention relates to a kind of bont.

Background technology

The known bay-lift that is provided with a kind of with an actuating device, i.e. dolly aspect bont.

Summary of the invention

Therefore the safety that the objective of the invention is to improve equipment.

According to the present invention, this purpose is through realizing by the described bont of the characteristic in the claim 1.

The key character of bont of the present invention is, can be at a rod member, comprise that particularly pilot trolley moves on the rod member of track and/or tooth bar,

Wherein can realize motion until one first height,

Wherein lay a primary wires system until second height along sense of motion,

Wherein dolly comprises an actuating device and a level coil, can be that said actuating device is supplied power contactlessly through this output primary,

Wherein output primary and primary wires system induction coupling,

Wherein second height is less than first height.

Its advantage is that said safety realizes through the lengthening running section, wherein in the zone of said lengthening, can not be the dolly intake.Therefore guaranteed safety from physical law, so safety is absolute (reliably).

In a kind of favourable structure, such serial or parallel connection one capacity cell of output primary, the oscillation frequency under making is equivalent to import the frequency of the electric current in the primary wires system basically.Its advantage is that therefore the guiding of dolly allows bigger tolerance, particularly bont can regard building hoist as.

In a kind of favourable structure; Second height is highly corresponding greater than changed into potential energy institute fully by kinetic energy with respect to the diff-H of first height; Wherein initial kinetic energy is relevant with the accessible maximum speed of actuating device here; Its advantage is to begin dolly is carried out the failure-free braking from each possible running state, so to have improved safety.

In a kind of favourable structure; The primary wires system comprises a feeder line and a loop line; Wherein feeder line and loop line are electrically connected on second height; Its advantage is, Magnetric pickup/pick-up coil (Pick-Up) can shift out from the primary wires system without barrier, wherein reverse for this reason winding (Umkehrschleife) with respect to the flat transverse ground of confirming by the primary wires system, specially be vertically directed.

In a kind of favourable structure, rod member is that the wheel of dolly comprises a track and/or makes a track, and its advantage is that dolly utilizes its wheel support on rod member, confirms the distance between output primary and the primary wires system thus.

In a kind of favourable structure, rod member is provided with a tooth bar, can be meshed with this tooth bar by the tooth parts that actuating device drives, and its advantage is to adopt the sealed actuating device of shape.But alternatively, but the also sealed type of drive of realizable force.

In a kind of favourable structure, bont is formed by same module combinations, wherein is provided with one at least not with the topmost module of primary wires system, and the primary wires system additionally is installed on a lower module at least.Its advantage is, can improve safety through on the basis of a necessary module, adding an add-on module.Therefore do not need special additional expense.

Other advantages are provided by dependent claims.The present invention is not limited to the characteristics combination of claim.Particularly from the proposition of task and/or from proposing through the comparison with prior art of task, those skilled in the art can obtain other rational combinatory possibility of the characteristic of claim and/or individual event claim characteristic and/or specification sheets and/or accompanying drawing.

Description of drawings

Illustrate in greater detail the present invention by means of accompanying drawing now.

At a bont of the present invention shown in Fig. 1,

The enlarged drawing of the part of the bont among Fig. 1 has been shown in Fig. 1 a.

The specific embodiment

One building is provided with a bont; This bont comprises a rod member; One tooth bar 3 is installed on this rod member; The dolly 4 and load-carrying 2 that comprise a voltage transformer head---cage particularly goes up and down---are connected and comprise an actuating device, and therefore this actuating device and tooth bar engagement also can produce dipping and heaving.Actuating device comprises an electrical motor, and this electrical motor is by an inverter supply, and this frequency converter can pass through the output primary power supply, and this output primary is arranged to be coupled with the primary wires induction of extending, lay along rod member.At this, input one electric current of intermediate frequency in primary wires, this electric current preferably has the frequency of 10kHz to 100kHz.Such serial or parallel connection one capacity cell of output primary makes affiliated oscillation frequency basically corresponding to this IF-FRE in addition.

Output primary is included in the voltage transformer head that is also referred to as Magnetric pickup.

Feeder line 5 and loop line 6 be short circuit at one end through in the groove of an end piece 7, interconnecting via a reverse winding.

As clearly visible by Fig. 1, rod member 1 and tooth bar 3 are provided with to such an extent that the position at ratio inverse winding place is high at vertical direction.

Therefore though dolly 4 can go to such an extent that the position of ratio inverse winding is high together with its pickup that comprises output primary, degradedness supply when surpassing the position of reverse winding.

The residue length that surpasses this position that comprises the running rail of rod member and tooth bar is selected like this, makes the kinetic energy relevant with the accessible maximum speed of in the vertical direction be equivalent to the potential energy that when passing by residue length, is increased at least.

In this way, making is expert at is transformed into potential energy with kinetic energy at most when crossing, by means of gravity motion is stopped then and oppositely.

The primary wires system that comprises feeder line 5 and loop line 6 can snap in the plastic cloth line style material, and these wiring section bars are arranged on the lower module of the bont that in Fig. 1, is made up of two modules and can be connected removably.On upper module, there are not this wiring section bar and primary wires system.

Therefore can improve the safety of the bont of built modular one-tenth through the module that only puts a topmost.
