The iron notch is drilled at a certain angle, so that molten iron flows out of the channel smoothly. The rock drill is an important component of the tapping machine, and mainly makes a drill rod rotate at a high speed and impact a tapping hole mud sleeve to drill a molten iron channel. Therefore, the stability and the opening capacity of the tapping machine directly influence the yield and the process operation of the ironmaking blast furnace.
The rock drill rotates to the position right above the molten iron major groove during operation, and is in a continuously high-speed rotation and striking state in the process of opening the tap hole channel and is in a high-temperature baking environment for a long time. Because rock drill belongs to accurate hydraulic equipment, can often take place to strike the trouble that inefficacy and rotation became invalid because of hydraulic seal damages the oil leak under high Wen Elie operating mode, need promptly dismantle and change trouble rock drill, otherwise unable opening the iron notch or open the iron notch difficulty. At present, manual disassembly and assembly are generally adopted for the failed rock drill, and because the rock drill is heavy in volume, the manual hoisting and alignment, disassembly and assembly modes are adopted for carrying out operation, and personnel are not only in a high-temperature environment, but also have complex operation process, high labor intensity and low working efficiency.
Disclosure of utility model
The utility model provides a dismounting device of a blast furnace rock drill, which can solve the problems of high labor intensity and low working efficiency when the rock drill fails and needs to be dismounted and replaced.
In order to solve the problems, the utility model adopts the following technical scheme: the lifting support comprises a base, walking wheels are arranged on the bottom surface of the base, upper supporting seats are respectively arranged on the front side and the rear side of the base, the bottoms of the upper supporting seats are fixedly connected with the base through lifting support columns, the two upper supporting seats are connected through support plates, and the two ends of each support plate are respectively connected with the inner sides of the upper supporting seats through hinges.
Among the above technical schemes, more specific technical schemes may also be: the left and right sides of the upper supporting seat are respectively hinged with a bending arm, the bending arms are composed of an upper arm and a lower arm, the connecting parts between the upper arm and the lower arm are connected through a rotating shaft, and the lower end of the lower arm is hinged with the base.
Further: a baffle plate is arranged on the support plate surface near the rear side along the width direction of the support plate and is used for positioning the tail part of the rock drill; and a concave supporting block used for supporting the rock drill head is arranged on the supporting plate surface near the front side along the width direction of the supporting plate.
Further: the travelling wheel is a universal wheel.
Further: the liftable support column is a jack.
Further: the base is formed by connecting and fixing two long plates on two sides and two short plates on two ends, and two jacks are respectively vertically arranged in the middle of the two short plates.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:
1. The travelling wheels are arranged below the bottom plate, so that the high-strength high-temperature drilling machine can conveniently and quickly move on an operation site, the manual hoisting is not needed when the drilling machine is assembled and disassembled, the bottom of the upper supporting seat is fixedly connected with the base through the liftable supporting columns, the lifting or descending contraposition of the drilling machine can be realized, the high-temperature drilling machine is suitable for the high-temperature working condition in front of a blast furnace, the replacement efficiency of the high-strength drilling machine of the blast furnace is improved, and the operation requirement of a high-strength tapping hole of the blast furnace is met.
2. The utility model has the advantages of stable operation, simple structure, safety, reliability, low cost, convenient maintenance and good operation effect.
