Technical Field
The utility model relates to a bell quick replacement elevating gear. Belongs to the technical field of metallurgical mechanical equipment.
Background
In the steel smelting industry, the high-quality steel ingot is the initial raw material of the forging industry, along with the improvement of the quality requirement of customers on the steel ingot and the upgrading and updating of downstream products, the high-quality steel ingot needs to be subjected to vacuum degassing treatment, the common mode is that a vacuum degassing furnace is adopted for degassing, a cover body of the vacuum degassing furnace is an important component of the vacuum degassing furnace, the cover body can effectively shield the high-temperature radiation of molten steel in the vacuum degassing process and prevent steel slag from directly splashing out, the damage of high temperature to other configured equipment is reduced, the smooth proceeding of the vacuum degassing refining process is ensured, meanwhile, the cover body also slows down the heat loss speed in the furnace body, and the quality of the degassed products is ensured.
At present, the requirement for producing steel grades is high, degassing treatment is carried out on all the steel grades, and the VD furnace equipment maintenance operation time or the tool replacement time directly influences the production normal organization. The manual replacement of the shielding cover basically takes 5-6 hours, which seriously restricts production and reduces production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a bell quick replacement elevating gear is provided to above-mentioned prior art, saves the change time, improves the operating efficiency, reduces intensity of labour.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a bell quick replacement elevating gear, includes elevating base the last vertical bracing piece that is provided with of elevating base, bracing piece top is for supporting the mesa, and the shielding lid steadily arranges in on supporting the mesa supporting mesa below is provided with the support frame, and support frame and supporting mesa fixed surface are connected be provided with a pair of support arm and take hydraulic lock hydro-cylinder between elevating base and the support frame, a pair of support arm one end articulated with elevating base, support frame respectively, the other end is connected through slide mechanism and elevating base, support frame cooperation respectively, take the both ends of hydraulic lock hydro-cylinder articulated with elevating base, support frame respectively.
Preferably, the height of the support rod is the height of the lowest point of the shielding cover from the ground.
Preferably, the sliding mechanism is a balance travelling wheel, and the balance travelling wheel is respectively in sliding fit with the lifting base and the track on the supporting frame.
Preferably, the pair of supporting arms are arranged in a scissor-type crossing manner, and the middle positions are hinged with each other.
Compared with the prior art, the utility model has the advantages of:
1. the lifting of the oil cylinder is utilized to form the lifting power of the furnace cover, the oil cylinder adopts the oil cylinder with a hydraulic lock form, and the oil cylinder is prevented from pressure loss due to oil pipe bursting
2. Utilize scissors formula support arm structure to form stable bearing structure, ensure the stability of shielding lid in the lift in-process.
3. The supporting table top is arranged at the upper part of the table top, so that the load of the whole table top is uniform, and the local stress deformation cannot be caused.
4. After the furnace cover is cooled, the lifting device is arranged below the shielding cover, the furnace cover is lifted by jacking, and after the connecting pin shaft is removed, the furnace cover falls down and is replaced, so that the replacement time is saved by about 2.5-3 hours, the operation efficiency is improved, and the labor intensity is reduced.
