DD264408A1 - ARRANGEMENT FOR AUTOMATIC TILTING OF A SWIVELED HOLDER - Google Patents

Abstract

The invention relates to a constructive solution for tilting suspended on lifting large containers for emptying. The aim is the replacement of manual activity and the reduction of the required equipment and operating expenses. It is the object of developing a locking and unlocking for tilting, which can be actuated by elementary movements of the hoist. To solve an arrangement is proposed in which a tilting bearing vertically movable yoke is connected via a movement-connected length-variable coupling member with a bolt which acts against the existing tilting moment with a stop on the container. As a coupling member, a known Drehrasthuelsenmechanismus is used, which is switched by raising and lowering of the yoke by means of hoisting alternately on locking and unlocking. The arrangement can be used wherever it is necessary to tilt large containers moved by means of hoists. The arrangement is shown in FIG. Fig. 1

Field of application of the invention

The invention relates to elno constructive solution for the tilting of large containers by operating the hoist for the purpose of emptying.

Preferred application area are trough-like Sammelbehalter for material waste.

Explanation of the known prior art

For tilting pivotally suspended large containers manually confirmable devices that optionally act on gear known. The operation of these devices sometimes constitutes a considerable physical effort and may be associated with hazards depending on the particular technological process.

To tilt serving on the container located powered equipment need elno energy supply via the Hobezeug or a stationary supply system. In non-permanent connection between the container and hoist and larger transport of the container when supplied from stationary systems a continuous coupling and uncoupling of the power supply is required. It is also known to use for tilting large containers, a second hoist or equipped with Hilfsshubwerk hoist.

With DE-OS 3428089 a tiltable transport container is proposed, which can be tilted by means of only one crane hoist in cooperation with the base without manual intervention, emptied and can be set up again. For this purpose, the arms of the container cross-bottom open U-shaped yoke are provided at their side facing the container with two pins. For the upper pins on the container each releasable receptacle and for the bottom of each three different, interconnected shots, which represent a closed curve, provided. Due to the succession of different crane movements, the upper pins are brought into or out of the upper receptacle, wherein the lower pins occupy different engagement positions, as a result, a tilting, turning and re-erecting of the container takes place. The disadvantage of this solution is that for a Arbeltszyklus six vertical movements, which must be superimposed in part by metered horizontal movements, are required. The cause of this disadvantage is that the yoke for unlocking and locking must perform a geometrically complicated movement by disengaging and locking the upper pin.

Object of the invention

The aim of the invention is the replacement of manual activity when tilting large containers by hoist and the reduction of the required equipment and Bedisnaufwandes.

Explanation of the essence of the invention

The invention has for its object to develop a locking and unlocking for the container relative to the remaining in the vertical suspension, which is switched by an alementare movement of the hoist used for transport.

According to the invention dig task is solved in that the container is supported with a horizontally located outside the tilt axis center of gravity in the tilt axis of two bearing levers, to which the arms of a cross-down U-shaped yoke are arranged to be movable in a substantially vertical direction and a An edom bearing lever hinged with a stop on the container cooperating latch via a bewegungsschaltbares variable-length coupling member is pivotally connected to the respective Jocharm.

According to an advantageous embodiment, the mobility of Jochnrme compared to the bearing levers by at least each

· - · realized two mutually parallel coupling oscillations. The invention is further advantageously configured by As

p. -j, motion-switchable variable-length coupling member a Dhrasthülsenmechanlsmus is used.

The advantageous effect of the arrangement according to the invention is that the gravitationally lowered lowering movement of the yoke arm relative to the lever lifters upon release of the hoist in the motion-switchable coupling member respectively shifts another starting position for subsequent lifting. In the following long position, the coupling member is pulled apart by the free stroke length between Jocherm and Ligerhebel, so that the bolt is not deflected and the container can not tilt.

In the short position, the initial position curch by releasing the Joe is switched from the long position, the coupling member when lifting only a waitaus lower Betri g can pull apart than at long division, so that deflected at free stroke length between Jocharm and bearing lever of the bolt and the existing Tipping moment the resistance is withdrawn. The realization of the leadership of Jocharmen and bearing levers to each other by coupling swing is structurally less expensive than a sliding guide and at the same time allows the synchronization of the switching operations on both sides by a tilt axis arranged in the torsionally rigid connection between two coupling wings. The use of a Drehrasthülsenmechanlsmus as variable-length coupling member guaranteed due to the constructive simplicity a high reliability and low wear. By means of the arrangement according to the invention, the switching operations required for handling large tiltable containers can be triggered solely by vertical movement of the carrying device of the hoist without manual intervention or use of other energy-operated auxiliary equipment.

embodiment The present invention is an example of an execution for an open-top container for material waste

described.

In the enclosed drawing show: Figure 1: the container with the inventive arrangement in side view Figure 2: the rotary sleeve mechanism used as a variable-length coupling member in section Figure 3: the developed switching curve of Drehrasstülsenmechanismus The container 1 is overlapped by the downwardly open U-shaped yoke whose yoke arms 2 on each side of the container

are articulated by means of coupling rockers 4 and 5 on the bearing lever 3. The articulation point for the untoro coupling rocker 6, which is connected to the lying on the other side by a nlchtdargestellt rigid axle, located at the same time in the tilting axis 6 of the container 1, whose center of gravity is located to the left of the tilt axis, approximately in the area between the Jocharmen.

On the horizontal arm of the bearing lever 3 is the cooperating with the stop 1 located on the container 8 7th

rotatably mounted. The connection between the latch 7 and the Jocharm 2 provides the articulated

Turning sleeve mechanism 9 is. To limit the stroke for the Jocharm 2 this is provided with the acting against the bearing si 3 stop 10. The am Container 1 fixed stop 11 serves to fix the former against the respective Jocharm 2 against the Tilt direction. The Drehrasstülsenmechanismus 9 consists essentially of the sleeve-shaped outer part 12, which with the upper Bearing eye 13 rigidly connected and provided with the switching curve representing circumferential recess 14 and is made

The inner part 15, which is guided in the outer part 12, is provided with the locking bolt 17 projecting into the recess and is connected rotatably about the longitudinal axis to the lower bearing eye 16 (FIG. 2).

The switching curve of the recess 14 shown in development in Figure 3 has in a cyclic sequence detents for the rest position 18,

the short position 19, the further rest position 20 and the long position 21, which occupies the shift pin 17 as a result of alternating perpendicular Jochbewegung under rotation of the inner part 15.

Is the shift pin 17 with the yoke lowered in the rest position 18 and the yoke is raised, so moved

the bolt 17, first relative to the switching curve vertically downwards and then slides on the slopes under rotation of the

Innenteils In the short position 19. With further lifting of the yoke until the stop 10 is applied to the bearing lever 3, the Latch 7 deflected and thereby released from the stop 8. The container 1 can now upon further lifting on its left of

the tilting axis 6 lying support contour tilted and thereby emptied. By lowering the yoke, the container returns to its normal position, wherein the stop 11 rests against the yoke 2 and the latch 7 engages the stop 8. Upon further lowering of the yoke of the switching pin 17 passes relative to the switching curve first vertically upwards and then the slope In the rest position 20. From this position, the switching pin 17 is moved to the long position 21 when lifting the yoke again, which is reached when the Anschalg 10th abuts the bearing lever 3. The container can now continue to be raised and transported without the latch 7 being deflected. If the container and again

Lowering of the yoke, the shift pin 17 from the long position 21 returns to the rest position 18th The technological process when transporting a container for waste material from its parking space for emptying into one Railway wagon and back is as follows: During the residence of the container for filling at the parking space, the rotary sleeve mechanism is in the rest position 20

in front. The transport takes place in the long position 21. Before emptying is a settling at the emptying on the wagon wall or a specially created device required, the rest position 18 is achieved. When lifting again, the

Container In short position 19 unlocked, tilted and emptied. After return transport in tilt position to the parking space takes place there

a tipping back by lowering, the rest position 20 is reached again.

Is the return transport of the container in the tilted state from the point of emptying to the parking space due to limited lifting height

•, 'or other reasons not possible, then at the point of emptying the tipping back by lowering. As the lowering after

the return transport to the normal position at the next lift would result in a tilting of the parking space, is either immediate

, after settling or immediately before the re-transport for emptying the yoke to switch from the

 'Resting position 18 to the rest position 20 to raise and lower again.
