Description

Attachment device for conveyor baskets and elevators. For convenient and The rails of the cage and connecting platform must be brisk operation of the hoisting cages or hanging benches are brought to the same height.

The attachment devices serve this purpose; also called »caps«.

Without special devices, even with the most skilful machine management A simultaneous and exact holding of both baskets in front of the stop platforms cannot be achieved. Even with an embarrassing adjustment that is hardly achievable in the company, the permanent The rope lengthening that takes place in deep shafts is the necessary for this Exact rope length is not available due to the rope length changing with changing loads be.

Today, the so-called steep, Lever or push supports that are built differently.

The operation of the attachments in general is as follows: The descending basket rests on a solid support at the filling point before the rising one lZorb has run over the suspended bench in order to access the by moving a hand lever in the free shaft profile advanced support. of the hanging bench attachment device. A damaging hanging rope forms over the lower basket when the rising one The basket is pulled over the hanging bench.

After the suspended bench supports have been advanced, the upper basket is lowered put on. Since the machine movement will continue a little, that disappears Hanging rope on the lower basket and appears on the upper basket. After using the baskets the supports of the hanging bench have to be pulled back so that the shaft for the departing basket becomes free.

The simple retraction of the supports under the basket is only possible with light baskets. With heavy baskets and especially when in use the support friction of a lower rope is too great to be overcome with simple means to be able to.

In order to allow the loaded supports to be withdrawn, the Basket previously lifted for the purpose of relieving the support. It turns out that way some inconveniences for the entire mining operation, which also extend to the rope and the machine operation (harmful impacts in the rope, Loss of time and energy).

So z. B. when lifting the basket resting on the hanging bench supports (for the purpose of withdrawing the supports) @ its hanging rope disappear, vinden, but instead (The basket in the shaft appears. The lifting (les on the hanging bench support en Ruh:, nrlen basket and (read the following lifting of the basket in the shaft Then (catching up) occurs with brisk pumping finitely damaging impact. He follows the lowering of the cork resting on the bench supports without prior lifting and when the hanging bench supports are withdrawn, they do not find a controlled one at the same time The lowering of the basket does the length of the hanging rope instead, so you still get a shock by the basket, deprived of its support and falling into the rope. The controlled lowering of the basket can be achieved by a special design of the attachment device.

The versions of the force-controlled lowering of the cage are now very different.

plan created wedge-shaped contact surfaces between the basket and the latch. A knee lever is used as a movement and support gear. Or the contact areas between the basket and the latch are horizontal; for this the bolt slides with its lower one Area on a slightly inclined inclined plane, which is dimensioned so that no automatic advancement of the bolt takes place -. @ det, but still a tensile force to be exercised on him when moving out.

These newer bodies consist of variously interlocking Supports, shafts, levers and tie rods, while at the bottom of the conveyor cage specially specially built attachment claws are attached.

What all these facilities have in common is that the attachment supports, as soon as the conveyor basket is to be lowered, use a hand lever underneath your conveyor cage will be pulled away. Before the basket going up, however, to the When the operating platform arrives, the supports are returned to their initial position, While they protrude into (read the free shaft profile. The continuous basket moves or then twist the supports until the @ler shaft is free. By their own weight the supports then fall back into their initial position and the basket can then put on.

However, the design of the attachment devices listed above is so intricate that they cannot be manufactured without great expense. In addition The various interlocking parts require careful execution and supervision in the company, otherwise they can easily fail and lead to operational disruptions and cause accidents.

All of these disadvantages are met by the one shown in Figs. I to .l Invention through its simple, powerful design while maintaining the force-controlled Lowering the basket.

The attachment supports here consist of round disks a, which are eccentric sit firmly on shafts b1 and g-2. The @ 'Vellen b' un, l b = are in turn strong Store c stored. The hand lever d required to move the discs a is seated firmly on the shaft b1. A little above the pivot point e (Fig. I) of the hand lever d grips a pull rod la with bolt f1 and fork g1. at. A short one sits on the shaft bü Lever i., On which the pull rod h. again by means of bolts f @ and fork ä = engages. So that now the eccentric rows a protruding into the shaft profile after passage of the basket that goes up will always fall back into its old position, sit on both shafts b1 and b = firmly wedged each a lever k with weights 1. On the The underside of the conveyor cage are particularly rounded, corresponding to the eccentric disks Attachment claws 3x attached (Fig.: L.).

The mode of action of this attachment device is as follows: The rising one The basket pushes back the eccentric disks a protruding into the free shaft profile, which after passage of the basket by virtue of the counterweights 1 in their previous position fall. The basket can be put down immediately without having to pull it up over the hanging bench to «-earth. After the basket has been processed, the eccentric disks are a by means of the Hand lever d withdrawn and the claws slide in the conveyor cage the periphery, the eccentric disks a slow .. sam from. After the basket the hanging bench has left, you turn the eccentric discs back into the free shaft profile into it.
