2, remove steel ingot slag to emit:
After crystallization, electroslag ingot top can form the slag of 150mm-250mm thickness and emits, need to through clashing into, clamping, mechanical system remove, just can be transported to ingot slow cool hole or annealing furnace.
3, the horizontal handling of steel ingot and horizontally rotate function around vertical axis:
In electroslag ingot entrucking or when entering burial pit, for reaching ingot axis working environment requirement, need to horizontally rotate adjustment steel ingot, to ensure that ingot axis is parallel with box body or burial pit body.
4, vertical overturn to horizontal steel ingot:
Electroslag ingot transhipment or storing process, it is generally required to electroslag ingot is in horizontal state handling, are changed to horizontal state orientation therefore it is required that electroslag ingot can do by vertical state.
5, horizontal stand to vertical steel ingot:
Require when electroslag ingot is smelted that consutrode or dummy electrode ingot vertically use, therefore it is required that the use function that electroslag ingot can be stood to vertical state by horizontal state.
Summary of the invention
The technical problem to be solved is: provides a kind of crane multi-functional clamp of electroslag ingot handling, can realize multiple handling mode, easy and simple to handle, and decreases potential safety hazard.
The present invention is adopted the technical scheme that in order to achieve the above object: the multi-functional clamp of a kind of crane for hoisting electroslag ingot, mainly include joining the clamp shackle plate hanging over crane main hook, clamp upper beam, the common axis of arm-tie inside and outside clamp shackle plate and clamp, arm-tie inside and outside clamp, arm-tie axle, caliper body central shaft, curb pins caliper, clamp side plate, thermal insulation board, for clamping the V-type rotary chuck of steel ingot, the steel wire rope used for secondary hook of crane traction, meet the steel wire rope swing rope device etc. of multi-faceted traction angle, it is characterized in that: inside and outside clamp shackle plate and clamp, arm-tie uses common axis structure;Be connected by can the V-type rotary chuck of any angle of revolution with caliper body;The folding of secondary hook of crane dynamic Control clamp, clamp upper beam both sides is utilized to be provided with steel wire rope swing rope device, connecting steel wire ropes different azimuth, achieve angle by traction servo-actuated.
Described common axis structure: be that arm-tie upper hinge axle inside and outside clamp shackle plate underneath hinges axle and clamp is used common axis structure, change the force way of traditional mechanical formula clamp clamping, reduce clamp total height, the quantity of minimizing hinge axis.
The V-type rotary chuck of described any angle of revolution: main by V-block, hemisphere face pedestal, axle body welding fabrication, with caliper body junction, end backing plate is used to realize axially location, use roller bearing and angular contact bearing radial positioning structure, can realize turning round at any angle, when solving electroslag ingot upset or stand, chuck rotates requirement.
Described steel wire rope swing rope device: be placed in clamp upper beam side, device bottom, equipped with fixed pulley, determines position, steel wire rope vertical force;Equipped with the eccentric web main shaft of rotatable pivot angle and design a pair pulley in two webs in the middle part of device, steel wire rope can pass around wherein;Device top is provided with the bearing cover that can bear moment of flexure;Can realize secondary hook of crane steel wire rope different azimuth traction time servo-actuated.
The invention has the beneficial effects as follows: expand range and the versatility of mechanical clamp, use a multi-functional clamp can complete electroslag ingot precognition basis handling, as the vertical handling of electroslag ingot, horizontal handling, electroslag emit removal etc., it is possible to resolve in Melting of Special Steels, ingot casting crouches and turns a vertical or vertical turn of sleeping upset operating mode difficult problem;The use of alternative ingot tipper and artificial lift spindle, it is to avoid potential safety hazard;Decrease the auxiliary equipment that special steel produces;Shorten the upset of ingot casting, handling time, improve work efficiency and reduce production cost, improve the market competitiveness.
