Abstract

The utility model relates to a triangular plate type anode lifting mechanism. A double-shaft extending motor 3 is fixed between two lifting jacks 2 through a motor frame 4. The utility model is characterized in that the front ends of the two lifting jacks pass through holes of a fixing plate 10 and are connected with a connecting rod 6 through a cross connecting block 5, and the interior of a connecting box 7 below the connecting box 6 is provided with a fork-shaped bolt 8 which is hinged with a hanging lug on the long side of a triangular plate 9. A hole on the right angle position of the triangular plate is hinged with a pivot shaft, and a hole of a short side of the triangular plate is connected with a hanging head 11 and a clamping plate 12. The design has the advantages that the fixing plate 10, the motor frame 4 and the extending lines of the two lifting jack work pieces form a closed parallelogram; the hinge position of the fork-shaped bolt is changed into the inside of the triangular plate from the central position of the triangular plate, and as a consequence, the utility model reduces outside dimensions of equipment and provides sufficient space for other equipment.

Description

The board-like anode lifting of triangle mechanism

The utility model relates to the board-like anode lifting of the triangle mechanism that gives roasting electrolytic aluminum groove top in the aluminium manufacturer.

During current electrolysis aluminium was produced, multiple special mechanical equipment work compound was to enhance productivity, so tight day by day to the spatial positioning requirement of equipment, all there is strict restriction the operating space of various specific equipments.Intrinsic this equipment, be for the localized mode of lifting-jack: respectively the two ends of a channel-section steel to be tightened on the retaining plate of each lifting-jack with bolt, be equivalent to three blocks of plates are connected as a single entity, see Fig. 1, the spatial accuracy requirement of whole space none sealing with bolt.This frame mode can't guarantee that two lifting-jack operating lines are in same horizontal plane inter-sync work, certainly will produce interference during equipment work, the load that the retaining plate of this structure is come for lifting-jack link rod biography in the operation is held and is dared not accept, gently then bolt frustrate disconnected, heavy then motor frame distortion or cause other damage of equipment.Also have, connect box and be positioned at the link rod outside, because the space occupy-place is bigger, occasion at multiple specific equipment work compound, closely cooperating of unfavorable and miscellaneous equipment, and deflection appears in this locations of structures easily that connect box when making burtoning, interfere the miscellaneous equipment works better, and easily cause structure deteriorate.

The design's purpose provides a kind of overcome above-mentioned shortcoming, the board-like hoisting appliance of triangle stable and reliable for performance.

The board-like anode lifting of a kind of triangle mechanism, be included in two hinged lifting-jacks 2 of crossbeam 1 two ends hanger, twin shaft is stretched motor 3 and is fixed between two lifting-jacks 2 by motor frame 4, it is characterized in that the two lifting-jack front ends that extend in parallel pass the hole of retaining plate 10, are connected with link rod 6 through cross connection piece 5; Retaining plate 10 constitutes the parallelogram that seals with motor frame 4 and two lifting-jack workpiece extension lines; There are the fork-shaped bolt 8 and the hanger on set square 9 long limits to link in the connection box 7 of link rod 6 belows, the hanger of its protrusion places in the prong of fork-shaped bolt, the hole of position, set square right angle and pivot hinge joint, the hole at its minor face angle with hang 11 and be connected with clamping plate 12, the other end of link rod also adopts identical set square and fork-shaped bolt arrangement to be connected on another pivot, and two clamping plate 12 join with anode.

The characteristics of the board-like anode lifting of the design's triangle mechanism are: 1. lifting-jack, link rod center are overlapped with set square hinge joint center; 2. designed at link rod and set square connection part and fixedly held up plate, can limit the link rod rotation, made the state of being kept upright; With intrinsic fork-shaped bolt in the set square centre hinged changing in the set square hinged inside, dwindled the device external size, for miscellaneous equipment provides sufficient room.

Embodiment:

The board-like anode lifting of a kind of triangle mechanism, be included in two hinged lifting-jacks 2 of crossbeam 1 two ends hanger, twin shaft is stretched motor 3 and is fixed between two lifting-jacks 2 by motor frame 4, it is characterized in that the two lifting-jack front ends that extend in parallel pass the hole of retaining plate 10, are connected with link rod 6 through cross connection piece 5; Retaining plate 10 constitutes the parallelogram that seals with motor frame 4 and two lifting-jack workpiece extension lines; See Fig. 2 .3, there is the box 7 of connection link rod 6 belows, and the screw thread rod end of fork-shaped bolt 8 passes and connects box body 7, is fixed in outside the box with nut; The hanger hinge joint on the fork end of fork-shaped bolt 8 and set square 9 long limits, the hanger of its protrusion places in the prong of fork-shaped bolt.The axle center of fork-shaped bolt overlaps with the work extension line of lifting-jack, link rod, sees Fig. 4.Set square is a scalene triangle, and each angular position is porose, and its position, long corner has with the set square all-in-one-piece in a side protrudes the flute profile hanger, also porose on it, sees Fig. 4.The hinge joint of the hole of position, set square right angle and pivot, the hole at its minor face angle with hang 11 and be connected with clamping plate 12, the other end of link rod 6 also adopts identical set square and fork-shaped bolt arrangement to be connected on another pivot, two clamping plate and anode join.

Connection box 7 outer walls one side has perpendicular to the extension of link rod fixedly holds up plate, props up the fork of fork-shaped bolt, and restriction link rod 6 rotates.

The shape of retaining plate 10, an integral slab, respectively there is a hole at two ends, match with the guide pin bushing flange of lifting-jack front end, around the hole mounting bolt hole are arranged, and see Fig. 5.For gaining in strength, entire plate can also have strengthening rib.
