Abstract
Disclosed is a double sealing connection structure for rock drilling tool on tap hole machine, which belongs to a spare part of the tap hole machine of blast furnace. The utility model comprises a drill pipe with a conic hole and a vibration bar with a ball head. Wherein, the drill pipe with a conic hole and the vibration bar with a ball head are arranged in the thread-connection sleeve and are connected with the thread-connection sleeve through thread, and sealing devices are arranged on both ends of the thread-connection sleeve; a ball-cone rigid sealing is arranged between the inner cone surface at the end of the drill pipe with a conic hole and the outside sphere surface of the vibration bar with a ball head. The equipment provides two sealing format of the sealing device on both ends of the thread-connection sleeve and the ball-cone rigid sealing between the inner cone surface at the end of the drill pipe with a conic hole and the outside sphere surface of the vibration bar with a ball head. With the sealing area between the drill pipe with a conic hole and the vibration bar with a ball head, leakage is eliminated, and the micro leakage at the ball-cone rigid sealing is also blocked by the sealing device. The utility model makes the rock drilling tool has anti-high temperature and anti-vibration sealing capacity.
Description
Technical field
The utility model relates to a kind of blast furnace open hole machine drill tool structure that is tightly connected, particularly a kind of blast furnace open hole machine drill tool double seal connecting structure that adopts sealing member and two kinds of seal form of ball awl positiver sealing.
Background technology
Iron perforater is the equipment that is used for beating tapping outlet that uses when ironmaking at present.Direct and hard, the red-hot curing stemming of drill bit contacts with the iron mouth during iron perforater work.Purging high pressure, high density water smoke can be suppressed dust, cooling drill bit during opening.Sealing property when present taphole drilling machine drilling rod and vibrating rod syndeton do not possess vibration.Taphole drilling machine is when adopting the aqueous air purge of high pressure, and moisture is bled into iron runner in a large number from the junction of drilling rod and vibrating rod, can't arrive drill bit.Water flows to the iron runner of red heat in a large number simultaneously, has serious potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of good sealing effect, has drilling tool sealed structure high pressure resistant, the vibration resistance ability.
The purpose of this utility model is achieved in that a kind of blast furnace open hole machine drill tool double seal connecting structure, comprise taper hole drilling rod 3 and bulb vibrating rod 4, taper hole drilling rod 3 and bulb vibrating rod 4 place in the cover 2 that is threaded, cover 2 is connected by screw thread 5 with being threaded, cover 2 two ends that are threaded are provided with sealing member 1, are between the spherical outside surface of taper hole drilling rod 3 inner end taper and bulb vibrating rod 4 ends that ball bores positiver sealing.
Blast furnace open hole machine drill tool double seal connecting structure provided by the utility model, by the two kinds of seal form of ball awl positiver sealing between the spherical outside surface that sealing member and taper hole drill rod end inner conical surface and bulb vibrating rod end are set at the cover two ends that are threaded, by between taper hole drilling rod and bulb vibrating rod, forming the ball seal strip, make the leakage basically eliminate, the leakage of ball awl sealing place trace also can sealed stops, and makes drilling tool have sealing property high pressure resistant, vibration resistance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model adopts following structure: a kind of blast furnace open hole machine drill tool double seal connecting structure, comprise taper hole drilling rod 3 and bulb vibrating rod 4, taper hole drilling rod 3 and bulb vibrating rod 4 place in the cover 2 that is threaded, with the cover that is threaded 2 by being threaded, cover 2 two ends that are threaded are provided with sealing member 1, are between the spherical outside surface of taper hole drilling rod 3 inner end taper and bulb vibrating rod 4 ends that ball bores positiver sealing.
The highly compressed atomized water was by high pressure runner 6 when taphole drilling machine purged.The inner conical surface of taper hole drilling rod 3 ends is close to when being threaded mutually with the spherical outside surface of bulb vibrating rod 4 ends, freely feels relieved.The ball awl changes tighter and tighter when being sealed in taphole drilling machine work, forms the sealing of ball band gradually, makes the leakage basically eliminate.Sealed 1 oral area at the cover 2 that is threaded of the micro-leakage of ball awl sealing place stops fully.Two seal form one hard are soft does not disturb acting in conjunction mutually; Compressive seal is effectively alleviated vibration, prevents the pine holder.
Claims (1)
