Description

Technical Field

[0001] The utility model relates to the technical field of the connection of drill rods of an opener, in particular to a quick connection fixture for a drill rod of a blast furnace opener. Background Technique

[0002] The opener is an important device in front of the blast furnace. The drill rod of the blast furnace opener is installed on the opener in a threaded connection manner and is used to drill the taphole blocked by gun clay. Compressed air enters the air inlet at the tail of the drill rod, passes through the drill rod connecting sleeve and the drill rod, and finally blows out from the front end of the drill bit to realize the purging of the taphole passage. Therefore, the drill rod is a relatively expensive consumable. When the slag and iron flow is small due to reasons such as coke jamming or taphole drilling leakage at the taphole, it is not advisable to use an expensive drill rod to drill, but instead choose to use the self-produced thick threaded steel in the steel plant to replace the expensive drill rod to save production costs.

[0003] When using the self-produced thick threaded steel to replace the expensive drill rod, it is necessary to flatten the head of the threaded steel with a sledgehammer and then insert it into the flat head sleeve. The flat head sleeve is connected to the opener in a threaded connection manner. After connection, in order to prevent the threaded steel from falling off when drilling the taphole, it is necessary to tie it with iron wire, which is not only time-consuming and laborious, but also causes waste of iron wire, increases consumables without reason, and increases production costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quick connection fixture for a drill rod of a blast furnace opener aiming at the deficiencies and defects in the prior art. By using this quick connection fixture, not only the requirement for the operation level of workers is low, the operation is convenient and reliable, but also the working time of workers in the dangerous area of the taphole can be reduced, thereby effectively improving the operation safety, further saving production costs, and being more practical and convenient.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a quick connection fixture for a drill rod of a blast furnace opener, which includes a flat head sleeve 2 and a quick connection fixture 3.

Specific embodiments

[0022] Embodiment 1

[0023] Refer to Figures 1-7 As shown, the technical solution adopted in this specific embodiment is: it includes a flat head sleeve 2 and a quick connection clamp 3. The quick connection clamp 3 is sleeved on the outer side of the flat head sleeve 2. The quick connection clamp 3 includes a hoop cylinder 32. The hoop cylinder 32 is composed of a first cylinder A and a second cylinder B. A connecting hinge 31 is installed at the connection of one side of the first cylinder A and the second cylinder B. And an upper seamless steel pipe 34 is welded on the other side of the first cylinder A, and a lower seamless steel pipe 35 is welded on the other side of the second cylinder B. A connecting bolt 33 is sleeved between the upper seamless steel pipe 34 and the lower seamless steel pipe 35, and a connecting nut 36 is threadedly connected to the connecting bolt 33.

[0024] Furthermore, the front end of the flat head sleeve 2 is provided with a flat head sleeve connection head 201 with threads, and the flat head sleeve 2 is threadedly connected to the arcuate adapter sleeve 1 of the taphole machine through the flat head sleeve connection head 201. By inserting the flat head sleeve connection head 201 into the arcuate adapter sleeve 1 of the taphole machine, it is convenient for the flat head sleeve 2 to connect to the blast furnace taphole machine.

[0025] Furthermore, a flat head sleeve connection hole 101 facilitating threaded connection of the flat head sleeve 2 is provided at the opening of the arcuate adapter sleeve 1 of the taphole machine.

[0026] Furthermore, a deformed steel bar 4 is installed at the rear end of the flat head sleeve 2.

[0027] Furthermore, the hoop cylinder 32 is formed by symmetrically cutting a seamless steel pipe in half along the midline to form a first cylinder A and a second cylinder B. Using an integrated seamless steel pipe to manufacture the hoop cylinder 32 can ensure the integrity and stability of the hoop cylinder 32.

[0028] Furthermore, the central axis of the upper seamless steel pipe 34 and the central axis of the lower seamless steel pipe 35 are on the same axis. Making the upper seamless steel pipe 34 and the lower seamless steel pipe 35 on the same axis can facilitate the insertion and connection of the connecting bolt 33.

[0029] Further, gaskets 37 are welded at the openings at both ends of the hoop cylinder 32. A circular through-hole with a diameter of 45 mm is provided in the middle of the gasket 37 at one end, and a circular through-hole with a diameter of 35 mm is provided in the middle of the gasket 37 at the other end. Through the gasket 37, the sizes of the front and rear ends of the channel of the hoop cylinder 32 are inconsistent. The larger end can hold the flat head sleeve 2, while the other end holds the threaded steel 4.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the quick connection clamp 3 and the flat head sleeve 2 are welded to each other. The flat head sleeve 2 and the quick connection clamp 3 are welded into one body, so that they can be integrally installed during installation, without the need for two installations, improving the work efficiency of the staff.

[0032] The working principle of the present utility model: After the operator installs the flat head sleeve 2 on the arc-shaped adapter sleeve 1 of the taphole machine through threaded connection, the pre-made threaded steel 4 is inserted into the flat head sleeve 2. The quick connection clamp 3 is sleeved at the junction of the threaded steel 4 and the flat head sleeve 2, and its large-hole end holds the flat head sleeve 2, and the small-hole end holds the threaded steel 4. Then, the first cylinder A and the second cylinder B are combined, and the connecting bolt 33 is passed through the upper seamless steel pipe 34 and the lower seamless steel pipe 35, and then the connecting nut 36 is installed to complete the installation of the quick connection clamp 3. After the operator completes the above operations, he leaves the taphole area to perform taphole drilling operations. Among them, the operator can also weld the lower half of the quick connection clamp 3 to the flat head sleeve 2. When installing the flat head sleeve 2, the quick connection clamp 3 and the flat head sleeve 2 are installed on the taphole machine together. The large-hole end faces the flat head sleeve 2, and the small-hole end faces the threaded steel 4. When the threaded steel 4 needs to be installed, the connecting hinge 31 is opened. After the threaded steel 4 penetrates into the flat head sleeve 2, the connecting hinge 31 is closed, and the connecting bolt 33 is passed through the seamless steel pipe 34 and the lower seamless steel pipe 35, and then the connecting nut 36 is installed.

[0033] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
