Referring to fig. 1 to fig. 3, a refractory fixing structure according to an embodiment of the present invention includes a refractory 10, a fixing member 20, a conical head screw 30, a lock nut 40, a guide rod 50, and a fastening sleeve 60.
In the present embodiment, the refractory 10 is a large refractory having a constant thickness. The press plate 11 is embedded in the refractory material 10, wherein the press plate 11 can be integrally formed with the refractory material 10, that is, one press plate 11 can be placed in the refractory material 10 during the casting process. The pressing plate 11 is provided with a through hole 111, and the upper side and the lower side of the position of the through hole 111 on the pressing plate 11 of the refractory material 10 are respectively provided with a first channel 12 and a second channel 13. In the present embodiment, the groove diameter of the second passage 13 gradually increases from the direction away from the platen 11, that is, the second passage 13 has a tapered hole structure to guide the insertion of the conical-headed screw 30 into the refractory 10.
Further, the portion of the conical head screw 30 connected to the fixing member 20 in the present embodiment is configured to match the conical structure of the second channel 13, so that when the conical head screw 30 is inserted into the first channel 12, the portion of the conical head screw 30 disposed in the second channel 13 abuts against the inner wall of the second channel 13, thereby ensuring the coaxiality between the conical head screw 30 and the second channel 12.
The conical head screw 30 is fixedly connected to the fixing member 20 and can be matched with the lock nut 40, and the refractory material 10 and the fixing member 20 are fixedly connected, wherein the conical head screw 30 is provided with a connector 31 at one end far away from the fixing member 20, and the guide rod 50 can be fixedly connected with the conical head screw 30 through the connector 31, so that the guide rod 50 and the conical head screw 30 are assembled and connected. Wherein, the pressure plate 11 is arranged perpendicular to the conical head screw 30.
In the present embodiment, the connection head 31 of the present embodiment is provided with a male screw (not shown), the guide rod 50 is provided with a female screw (not shown) matching with the male screw, and the guide rod 50 and the connection head 31 are fixedly connected by the thread fit between the male screw and the female screw. That is, the guide bar 50 of the present embodiment is screwed to the coupling head 31 of the conical-head screw 30, so that the guide bar 50 and the conical-head screw 30 can be easily attached and detached. In order to ensure that the portion of the guide rod 50 inserted into the first channel 12 can be screwed with the connecting head 31 of the conical-head screw 30, the guide rod 50 can be sleeved with a structure capable of abutting against the inner wall of the first channel 12, so as to guide the process of inserting the guide rod 50 into the first channel 12. It should be noted that the connection manner between the connecting head 31 and the guiding rod 50 is not limited to that shown in the drawings, and it is obvious to those skilled in the art that an internal thread may be provided on the connecting head 31 and a corresponding external thread may be provided on the guiding rod 50, or that an insertion hole may be provided on the connecting head 31 and two blocking pieces (not shown) may be symmetrically provided at the opening position of the insertion hole, and correspondingly, the guiding rod 50 is provided with two corresponding protruding pieces (not shown), and the limiting is performed by using the abutting between the protruding pieces and the blocking pieces, which will not be described herein.
The conical head screw 30 of the present embodiment can sequentially pass through the second channel 13 and the through hole 111 and extend into the first channel 12, and the guide rod 50 can be inserted into the first channel 12 and is connected and fixed with the connector 31 on the conical head screw 30; the lock nut 40 of the present embodiment can enter the first channel 12 along the axial direction of the guide rod 50, that is, the guide rod 50 of the present embodiment can guide the process of placing the lock nut 40 into the first channel 12 of the refractory material 10, and prevent the lock nut 40 from falling down in the process of placing the lock nut 40 into the first channel 12 of the refractory material 10, so as to ensure that the lock nut 40 placed into the first channel 12 can be accurately sleeved on the tapered screw 30. The refractory of the present embodiment has a large thickness in the axial direction of the guide rod 50, so that the lock nut 40 may not be tilted and may not be aligned with the conical-headed screw 30 during the process of being inserted into the first passage 12 under the guide of the guide rod 30.
The conical head screw 30 of the present embodiment is vertically connected to the fixing member 20, and the refractory material 10 is located above the fixing member 20, so that the lock nut 40 can fall onto the conical head screw 30 along the axial direction of the guide rod 50 under the action of gravity, thereby facilitating the placement of the lock nut 40 into the first channel 12 of the refractory material 10. That is, in the refractory fixing structure of the present embodiment, the refractory 10 and the fixing member 20 are horizontally installed, so that the lock nut 40 can fall onto the conical-headed screw 30 by gravity. It should be noted that, of course, when the refractory material 10 and the fixing member 20 are not installed horizontally, the fastening sleeve 60 may be used to feed the lock nut 40 into the first channel 12 of the refractory material 10 until the lock nut 40 is engaged with the conical-head screw 40 and locked, which will not be described herein.
The fastening sleeve 60 is applied to the refractory fixing structure, and is used for screwing the lock nut 40 so that the lock nut 40 is screwed to the conical head screw 30.
It can be understood that, when the fastening sleeve 60 is used to screw the locking nut 40 in the present embodiment, the locking nut 40 is specifically driven to be spirally selected onto the conical head screw 30 until the locking nut 40 abuts against the pressing plate 11, and the conical head screw 30 is limited on the pressing plate 11, so that the fixing member 20 and the refractory material 10 are connected and fixed. When the lock nut 40 of the present embodiment is locked to the conical head screw 30, the portion of the thread structure 32 of the conical head screw 30 that can engage with the lock nut 40 is located in the second channel 13, so that the lock nut 40 can be locked with the conical head screw 30 that partially protrudes from the pressure plate 11.
Specifically, the fastening sleeve 60 of the present embodiment includes a sleeve body 61, and a handle 62 disposed on the sleeve body 61, wherein the sleeve body 61 is provided with a groove 611 at an end away from the handle 62, and a groove wall of the groove 611 is disposed to match with an outer peripheral wall of the lock nut 40. When the fastening sleeve 60 acts on the lock nut 40, the groove 611 of the sleeve body 61 on the fastening sleeve 60 can be inserted into the outer peripheral wall of the lock nut 40, and the rotation-stopping connection between the groove wall of the groove 611 and the outer peripheral wall of the lock nut 40 is realized by utilizing the fit between the groove wall of the groove 611 and the outer peripheral wall of the lock nut 40, so that the sleeve body 61 is driven by the handle 62 to rotate, the lock nut 40 can be driven to rotate on the conical head screw 30, and the handle 62 is driven to be pressed downwards towards the pressing plate 11, so that the locking nut 40 can be locked on the conical head screw 30 by the fastening sleeve 60.
The outer peripheral wall of the sleeve 61 is circular, and correspondingly, the inner wall of the first channel 12 can be circular to match the outer peripheral wall of the sleeve 61, so as to reduce the aperture of the refractory 10 in which the first channel 12 is formed. Preferably, the inner diameter of the first channel 12 is equal to the outer diameter of the sleeve body 61, so that for connecting and fixing the refractory material 10 with the fixing member 20, only the first channel 12 with the diameter equal to the outer diameter of the sleeve body 61 needs to be formed on the refractory material 10, thereby avoiding forming a large hole on the refractory material for assembling the lock nut 40.
In addition, in the refractory fixing structure of the present embodiment, the locking nut 40 locks the conical head screw 30 penetrating through the pressing plate 11 to the pressing plate 11, and realizes the connection and fixation of the refractory 10 and the fixing member 20, and then when the enterprise applies the refractory 10 and the fixing member 20 assembled and fixed, the slurry of the refractory can be poured into the first channel 12 again, so that the end surface of the refractory 10 far from the fixing member 20 is in a planar structure; and when the assembled and fixed refractory 10 is used for a certain period of time and needs to be replaced, the refractory 10 can be directly broken to expose the lock nut 40, and then the lock nut 40 is reversely screwed by the fastening sleeve 60, which will not be described herein.
The invention also claims a refractory material fixing mode, which comprises the following steps,
the method comprises the following steps: driving a conical head screw rod 30 on the fixing piece 20 to penetrate through a pressing plate 11 in the refractory material 10;
step two: connecting the guide rod 50 to the part of the conical head screw rod 30 penetrating through the pressure plate 11, and then putting the locking nut 40 onto the conical head screw rod 30 along the axial direction of the guide rod 50;
step three: the lock nut 40 is screwed with the fastening sleeve 60 so that the lock nut 40 is screwed to the conical-head screw 30.
In this embodiment, the method further includes, between step two and step three: before the guide rod 50 is detached from the conical head screw 30, i.e., before the lock nut 40 is screwed by the fastening sleeve 60, the guide rod 50 is detached from the conical head screw 30 so as not to interfere with the first channel 12 of the fastening sleeve 60, which is inserted into the refractory 10, by the guide rod 50.
In summary, the structure and the method for fixing the refractory provided by the invention realize the limit between the refractory and the fixing piece by the matching between the conical head screw rod and the locking nut, so that the connection and the fixation between the refractory and the fixing piece are realized, and the effect of improving the connection strength between the refractory and the fixing piece is achieved; meanwhile, the guide rod is used for guiding the locking nut to be placed into the refractory material, so that the locking nut placed into the refractory material can be accurately placed into the conical head screw rod, the locking nut is locked on the conical head screw rod through the fastening sleeve, a large hole for assembling the locking nut is prevented from being formed in the refractory material, and the effect of facilitating the screwing of the locking nut on the conical head screw rod is achieved.
