Fixture device of tandem-connection graphite electrode group and hoisting crown block with fixture device

Abstract

The invention discloses a fixture device of a concatenation graphite electrode group. The fixture device of the tandem-connection graphite electrode group comprises a fixture transverse beam, a fixture opening and closing mechanism and a plurality of sets of clamping mechanisms, each set of clamping mechanism comprises two sets of linkage mechanisms symmetrically mounted on the fixture transversebeam, each set of linkage mechanism includes a pull lever hinged to the fixture transverse beam, curved arms hinged to the lower end of the pull lever, a connecting beam horizontally hinged between the two curved arms, a balanced linkage hinged to the corresponding connecting beam, and a special-shaped clamping arm hinged to the lower ends of the curved arms and the balanced linkage, the fixture opening and closing mechanism comprises a dual-output-shaft speed reducing motor, the dual-output-shaft speed reducing motor drives a reel to rotate through a coupling, the two ends of the reel are mounted on the fixture transverse beam through a bearing seat, a wire rope is arranged on the reel in a winding mode, and the lower end of the wire rope is fixedly connected with each connecting beam. The invention can achieve once clamping of two tandem-connection graphite electrode groups arranged in a parallel mode, the work efficiency is improved greatly, and a further provided hoisting crown block can achieve once clamping and transporting of the tandem-connection graphite electrode groups after being grouped is completed.

Description

technical field [0001] The invention relates to the field of hoisting and transportation, in particular to a clamp device for clamping series-connected graphite electrode groups and a hoisting crane provided with the series-connected graphite electrode group clamp device. Background technique [0002] At present, in the production process of graphite electrode roasting, it is necessary to lay a layer of filling material in the material box of the graphite electrode roasting furnace chamber, and then use a crane (electric single beam) with a single graphite electrode sling to hang or hook bridge crane) several times to hoist multiple graphite electrodes into the filling material in the material box of the roasting furnace chamber in series, and then insert graphite pads between the ends of the two graphite electrodes in sequence. ——This process requires workers to enter the material box of the roasting furnace chamber and work on the filling material, and manual intervention ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of low production efficiency and poor working environment of workers in the existing production process, one object of the present invention is to provide a fixture device for series-connected graphite electrode groups, and another object is to provide a device with series-connected graphite electrode groups. The hoisting crane of the fixture device can clamp, transport and place the graphite electrodes in groups after the series connection and marshalling at one time in the material box of the roasting furnace room, and can also place them in the material box of the roasting furnace room. After firing, the series-connected high-temperature graphite electrodes are clamped, transported and placed on the ground at one time
