The wedge thimble is designed for the transport-vessel suspension of a more-ropes winding machine and after the loading capacity reanalysis this basic type may also be used for a singlerope winding machine. It is suitable as replacement of the existing thimbles type Schönfeld or Droste, that is why it is manufactured in the size line of these thimbles.
The rope is clutched in the self-locking wedge between the bars and the heart. After the rope setting into the clutch the heart position is assured with female screws and the control bracket is fixed.
The new technical solution under the type marking AD consists in the combination of the design execution of the carrier slot and the side frame hinges of the product that leads to a higher quality of the machinery manufacturing of the product – a more accurate production connected with a steadier distribution of the loading forces to the thimble carrying parts. The individual main parts are stated in the picture: the side frame (1) is the basic carrying part, where the clutching load is transfered on one side via the bar (2) and hinges , and on the other side via the bar (3) with the slot. The bar (4) transfers the carrying force from the hinge pin (9) via hinged bushing (5) on the side frame (1) via the slot as well. The hinges (7) are locked with wedges, the heart (6) is locked with a screw through a disc spring and the bars (3 and 4) are fixed in the side frame with screws bonded with plied saddles – by the other modification the bar (4) is fixed with countersink screws. The rope is conducted out from the thimble by the end clamping (8) with the specified control bracket (10). The heart is shot out
Safety: The product complies to the Public Notice No. 22/1989 Coll. of ČBÚ (Czech Mining Office Board) and especially to the Public Notice No. 415/2003 Coll., § 39.
Delivery: The products is delivered with a protective surface zinc coating and painting; working surfaces are protected with preserving oil. The product is accompanied by 2 pc of the heart drift wedges; a set of 4 thimbles is delivered with the assembly jig. The integral part of the delivery is the accompanying documentation: the assembly drawing, Operation Manual, the list of spare parts, Manufacturer´s Certificate, material certificates, Test Reports and static calculation. If ordered it is also possible to deliver the hinge pins (9) with locking.
Assembly: The assembly shall be performed only by experienced and trained workers authorized for this work by the organization leadership. The rope end in the thimble must be surface-ungreased with technical benzine, the thimble-contact surface must also be clean – free of painting and rusting, ungreased. After the rope end lacing through the thimble the heart is inserted in the rope eye and the heart is tucked in the contact with the rope. After the rope clutching the thimble is strong, the heart position is locked with screw nuts. The overhanging part of the rope shall be bandaged, fastened in a clamp in the upper part of the thimble and deflected so that the ropes do not touch. The control bracket is fastened on the rope, it shall be placed by 5-10- tuple of the rated rope diameter above the thimble. The distance between the thimble and the bracket shall be measured and carried to the Book on the Rope Ride. The thimble for the mounting must be completely assembled; it is necessary to check the hinges and screws tightening. The hinge pin (9) shall be locked after the mounting with a safety pin.
