Description
Technical field
The utility model belongs to refining equipment field more particularly to a kind of LF furnace terminal clamp maintenance tool special for dismounting.
Background technique
LF furnace terminal clamp is by disc spring clamping, the hydraulic device loosened, which is casting fine copper material, internal water flowing
It is cooling.When terminal clamp hydraulic cylinder breaks down, terminal clamp can not just be loosened, electrode can not just take out.Usual way
Are as follows: terminal clamp is unclamped with 20 tons of hydraulic jacks, extracts electrode out, hydraulic jack is then measured and opens gap distance, press
This distance one section of one writing brush of gas welding gas cutting, this section of pipe is put into wherein, hydraulic jack is then unclamped, hydraulic jack is taken
Out.The steel pipe in gap is cut off with gas welding again, residual pipe is taken out into post-processing terminal clamp hydraulic cylinder failure.Such operational method
The shortcomings that are as follows:
1, because of the casting fine copper thin wall type structure that terminal clamp is internal water flowing, intensity is lower, and hydraulic jack and folder
Head contact surface is 20 disc of ∮, and terminal clamp stress surface is smaller, so terminal clamp is easily subject to crushing.
2, because this repairing operation need to use gas welding, relatively time consuming laborious, taking out electrode process generally needs 2.5h.
Summary of the invention
The utility model is intended to provide a kind of avoidable terminal clamp damage, improves the LF furnace terminal clamp inspection of operating efficiency
Repair extracting tool.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of LF furnace terminal clamp maintenance extracting tool, is respectively provided with a set of extracting tool in electric-pole horizontal arm two sides, described
Extracting tool includes tool assembly I, tool assembly II and hydraulic jack；The fourth that I system of tool assembly is made of mainboard and supporting plate
Font tabular component；Tool assembly II is whole to be made of substrate, top plate and baffle in T-shaped, top plate is fixed among substrate,
Substrate one end has baffle；The mainboard of tool assembly I is inserted in the gap between terminal clamp and electric-pole horizontal arm, and supporting plate sticks on
On electric-pole horizontal arm, for the baffle wedge of tool assembly II in the gap between terminal clamp and electric-pole horizontal arm, substrate sticks on electrode
On transverse arm, hydraulic jack is installed between the mainboard of tool assembly I and the top plate of tool assembly II.
Muscle is respectively equipped between the mainboard and supporting plate of tool assembly I and between the substrate and top plate of tool assembly II
Plate.
The utility model has the following beneficial effects:
The utility model is simple and practical, time saving and energy saving, convenient for operation, can shorten the repair time, improves operating efficiency；Can have
Effect avoids damaging terminal clamp in maintenance process, reduces spare parts consumption, reduces production cost.
Detailed description of the invention
Fig. 1 is I perspective view of tool assembly；
Fig. 2 is II perspective view of tool assembly；
Fig. 3 is terminal clamp maintenance extracting tool usage state diagram.
In figure: mainboard 1, supporting plate 2, gusset I 3, baffle 4, substrate 5, top plate 6, gusset II 7, hydraulic jack 8, electrode 9,
Terminal clamp 10, electric-pole horizontal arm 11.
Specific embodiment
It is in 11 two sides of electric-pole horizontal arm by attached drawing 1~3 as it can be seen that the utility model LF furnace terminal clamp overhauls extracting tool
It is respectively provided with a set of extracting tool.Extracting tool includes tool assembly I, tool assembly II and hydraulic jack 8.Tool assembly I
It is the T-shaped tabular component being made of mainboard 1 and supporting plate 2, gusset I 3 is equipped between mainboard 1 and supporting plate 2.Tool assembly II is whole
Body is made of, the centre of substrate 5 is welded with top plate 6,5 one end band of substrate in T-shaped baffle 4, substrate 5, top plate 6 and gusset II 7
There is baffle 4, gusset II 7 is equipped between substrate 5 and top plate 6.Pacify between the mainboard 1 of tool assembly I and the top plate 6 of tool assembly II
Equipped with hydraulic jack 8.
Maintenance extracting tool is in use, first install the extracting tool of side: the mainboard 1 of tool assembly I is inserted in electrode holder
In gap between first 10 and electric-pole horizontal arm 11, supporting plate 2 is sticked on electric-pole horizontal arm 11；The baffle 4 of tool assembly II is blocked again
In gap between terminal clamp 10 and electric-pole horizontal arm 11, substrate 5 is sticked on electric-pole horizontal arm 11.Then by hydraulic jack
8 are mounted between mainboard 1 and top plate 6, and apply certain pretightning force.According to the extracting tool of the above-mentioned steps installation other side.
Thereafter, two sides use hydraulic jack 8 to unclamp terminal clamp 10 simultaneously, hang away electrode 9.The pressure release simultaneously of two sides hydraulic jack 8,
Hydraulic jack 8 and tool assembly I, tool assembly II are unloaded, the failure of terminal clamp 10 can be handled.
