Description
Technical Field
The utility model belongs to the technical field of blast furnace maintenance equipment, concretely relates to special spanner is tightly drawn down to blast furnace.
Background
At present, a large hammer is completely used for a spring hook of a blast furnace tightness blowpipe, no auxiliary tool is used, 5-6 circles of screw threads need to be loosened for loosening the spring hook every time, a quarter circle of the spring hook can be loosened by striking three hammers, namely the spring hook for loosening one circle needs striking 12 hammers, at least 60-72 hammers are needed when the spring hook can be taken down completely, at least three persons are needed for alternately striking 60-72 hammers, the operation speed is slow, and labor and time are wasted. And because the blast furnace is shut down each time, more air supply devices are replaced, and more operators are needed, the assembly and disassembly of the spring hook can not be finished at one time because the assembly and disassembly of the spring hook can not be finished at one time in the cross operation, and because the assembly and disassembly of the spring hook are carried out by no person 1 meter outside the radius of the wheel hammer when the large hammer is hit each time, the sliding hammer is prevented from hurting people, and the object hitting is unsafe. The operation intensity is improved and the operation time is prolonged due to the influence of the spatial position no matter the blast furnace is disassembled or reassembled, and the method is a key link influencing the maintenance of the blast furnace.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a blast furnace is tight loading and unloading special spanner down to solve above-mentioned problem, reach blast furnace damping down and change loading and unloading that air supply arrangement can be faster safe and tight down, reduce intensity of labour, practice thrift change time's purpose.
In order to achieve the above object, the utility model discloses a technical scheme be:
the utility model provides a special spanner is tightly drawn down to blast furnace, includes the application of force pole steel pipe, the one end of application of force pole steel pipe is equipped with concentric disc, be close to concentric disc one side on the application of force pole steel pipe and be equipped with T type round steel, concentric disc and T type round steel and the tight solid device structure phase-match of drawing down.
Preferably, the included angle between the T-shaped round steel and the stress application rod steel pipe is 90 degrees.
Preferably, the T-shaped round steel and the concentric circular disc are perpendicular to each other.
Preferably, the axes of the stress application rod steel pipe and the concentric circular disc are on the same plane.
The beneficial effects of the utility model are that:
the utility model aims to solve the technical problem that a taut special spanner under dismouting blast furnace blowpipe is provided, this kind of spanner helps improving the speed of installation blowpipe, avoids the incident that takes place when dismantling down and tighten, reduces installer and reduction intensity of labour simultaneously, guarantees safety, shortens maintenance duration, improves maintenance work efficiency.
Drawings
FIG. 1 is a schematic view of the present invention;
FIG. 2 is a working state diagram of the present invention;
in the figure: 1. a concentric disk; 2. a stress application rod steel pipe; 3, T-shaped round steel; 4. a screw rod is tensioned downwards; 5. pulling down the fastening device.
Detailed Description
The invention will be further described with reference to the accompanying drawings and working principles:
the special wrench for the downward tensioning of the blast furnace shown in the figure 1-2 comprises a force application rod steel pipe 2, wherein one end of the force application rod steel pipe 2 is provided with a concentric disc 1, one side, close to the concentric disc 1, of the force application rod steel pipe 2 is provided with a T-shaped round steel 3, the concentric disc 1 and the T-shaped round steel 3 are structurally matched with the downward tensioning device 5, the concentric disc 1 can be sleeved on a downward tensioning screw 4 of the downward tensioning device 5, the T-shaped round steel 3 is clamped on a fastening bolt of the downward tensioning device 5, the force application rod steel pipe 2 is pulled to rotate along the concentric disc 1, and the downward tensioning device 5 can be disassembled and installed. The included angle between the T-shaped round steel 3 and the stress application rod steel pipe 2 is 90 degrees, so that the T-shaped round steel 3 is closer to the fastening bolt of the pull-down fastening device 5. T type round steel 3 and concentric disc 1 mutually perpendicular also are for laminating the structure of pulling down tightly solid device 5, dismantle more laborsavingly, and the laminating degree is high. The axes of the stress application rod steel pipe 2 and the concentric disc 1 are on the same plane, and the stress application rod steel pipe can rotate on the concentric disc 1 in order to ensure that the center of the stress application rod steel pipe rotates smoothly.
When changing blast furnace tuyere blowpipe, will the utility model discloses special spanner cover makes its T type round steel card on the spring hook fastening bolt, and clockwise anticlockwise rotation can realize the loading and unloading operation of spring hook fast, and the spring hook must the tight lead screw thread of elasticity 5-6 circles at every turn, and use this special spanner rotatory once can loosen the tight spring hook quarter round, that is to say elasticity round spring hook only need rotate this spanner four times can. The wrench is only required to be rotated 20 times to completely relax the spring hook to be removed. The wrench can be operated by one person or by two persons, and has the advantages of high operation speed, labor saving and time saving. Even if change a plurality of air supply arrangement, under the condition of cross operation, this spanner of can handling in a flexible way is not influenced, uses the utility model discloses behind the spanner, can effectively eliminate potential incident, have apparent social. The original loading and unloading of one lower tensioning body is carried out for 3-4 persons, each time of loading and unloading needs 40-70min, and the loading and unloading of the lower tensioning body can be realized by shortening the time to 2 persons within 20 min. Practice proves that the bolt can not be rotated by 1cm when the bolt is pulled down and is tightly pulled by the wrench, and then the bolt is knocked by a sledge hammer, so that the expected ideal effect is perfectly realized, the safety is ensured while the number of installation personnel and the labor intensity are reduced, the maintenance time is shortened, the maintenance work efficiency is improved, and the safe and stable smooth driving and pilot protection of the blast furnace are realized.
When the pull-down fastening device is assembled and disassembled, the special pull-down wrench disc is firstly sleeved on the lead screw 4, the T-shaped round steel 3 is adjusted to be suitable for being clamped on the pull-down fastening bolt 5, the pull-down disassembly behavior can be realized by anticlockwise rotation, the pull-down pre-tightening behavior can be realized by clockwise rotation of the wrench by the same method, and the pull-down disassembly and assembly can be safely and quickly realized.
