Description

Technical Field

[0001] The utility model relates to a glass kiln in the field of glass, in particular to a rolling automatic screw-lifting mechanism for a glass kiln. Background Art

[0002] At present, the heat storage chamber column adopts a fixed top screw mechanism, that is, the column, top screw and top plate are fixed structures, that is, the up and down cannot be adjusted, and the left and right can be adjusted manually. Disadvantages of this form:

[0003] 1. When the kiln heats up, the wall of the heat storage chamber expands and needs to move upward, but the top screw mechanism does not expand and does not move. The displacement difference between the two will cause the top screw mechanism and the wall to deform, causing safety hazards to the kiln.

[0004] 2. The insertion hole of the small furnace expands with the increase of temperature, resulting in left and right displacement. It is necessary to manually adjust the screw mechanism to ensure that it does not deform. The screw adjustment requires experience, which can easily cause the insertion hole of the small furnace to be damaged. It directly affects the service life of the kiln and brings economic losses to glass manufacturing companies. Therefore, it is necessary to use a rolling automatic screw mechanism for the glass kiln to realize the screw operation.

[0005] In the existing public documents, the patent announcement number CN204569707U discloses a crown support screw support mechanism. The screw support mechanism can not only automatically adjust the crown span size and the angle of the crown brick in time according to the expansion and contraction of the crown brick, but also effectively protect the brick structure from being squeezed and cracked. More importantly, when the glass furnace has a short and drastic temperature fluctuation, the crown brick does not need to be tightened and loosened in time. The phenomenon of upper or lower opening of any part of the crown is avoided, and the risk of the crown brick sinking is eliminated. The force of the screw outside the crown brick can be automatically adjusted according to the force of the crown brick, so that the crown is always in a safe state; however, the screw support mechanism has the following defects:

[0006] Although the screw-lifting mechanism can provide extrusion force to realize the screw-lifting operation when the glass kiln is rolling, the glass kiln will be in a rolling state during the screw-lifting process, and the screw-lifting part will generate greater friction with the glass kiln during the rolling process under the action of the extrusion force, which can easily damage the glass kiln. For this reason, a rolling automatic screw-lifting mechanism for a glass kiln is provided. Summary of the invention

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a rolling automatic screw-lifting mechanism for a glass kiln.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Rolling automatic jacking mechanism for glass furnace, including a socket block, a support shaft is fixedly installed on the inner wall of the socket block, and a jacking screw rotating mechanism is fixedly installed at one end of the support shaft; the jacking screw rotating mechanism includes a push column fixedly installed at one end of the support shaft, and a push rod is welded to one end of the push column. A jacking screw is arranged on one side of the push rod, and a guiding sliding ring is fixedly connected to the outer wall of the push rod; a limiting sliding column is slidably connected to the inner wall of the guiding sliding ring. A connecting column is welded to one end of the limiting sliding column, and a linkage block is installed at one end of the connecting column.

[0010] Preferably, the center points of the push column and the jacking screw are on the same horizontal line, and both the jacking screw and the push rod are made of stainless steel. A limiting sliding ring is fixedly connected to the outer wall of the connecting column, and the limiting sliding ring is slidably connected to the guiding sliding ring. The vertical cross-sectional shape of the limiting sliding ring is circular. An electric cylinder is fixedly installed on one side of the socket block, and a support block is welded to one end of the electric cylinder. The support block is used to support the electric cylinder.

[0011] When this technical solution is in use, the electric cylinder pushes the socket block to move to the right. The socket block drives the support shaft to move to the right. The push column carries the push rod to move to the right. The push rod carries the guiding sliding ring to move the limiting sliding column to the right. The connecting column carries the linkage block to move to the right. The tip of the jacking screw presses against the rolling part of the glass furnace. When the rolling part of the glass furnace rotates, the linkage block drives the connecting column to rotate. At the same time, the connecting column drives the limiting sliding ring to rotate. The limiting sliding ring rotates on the guiding sliding ring, and the jacking screw reduces the rotational friction with the rolling part of the glass furnace.

[0012] Preferably, a guiding mechanism is arranged below the support shaft; the guiding mechanism includes a socket support block arranged below the support shaft. Both sides of the socket support block are fixedly connected with connecting blocks. A guiding sliding rod is fixedly connected to one side of each connecting block.

A sliding block is welded to the bottom end of the socket block, and the sliding block is slidably connected to the sliding rail. Preferably, the two connecting blocks are symmetrically arranged with respect to the socket support block. The vertical cross-sectional shape of the connecting block is rectangular. The vertical cross-sectional shape of one end of the guiding sliding rod near the socket slider is hexagonal, and the outer wall of the guiding sliding rod and the inner wall of the socket slider are both smooth surfaces.

[0013] When this technical solution is in use, the socket support block supports the connecting block. The connecting block supports the guiding sliding rod. The socket block drives the sliding block to move to the right along the outer wall of the sliding rail. The sliding sleeve block moves to the right along the outer wall of the sliding rail. The sliding sleeve block drives the two socket sliders to move to the right, ensuring that the sliding sleeve block and the socket block can be guided to move to the right along the specified path.

[0014] Technical effects and advantages of the present utility model:

The tip of the setscrew presses on the rolling part of the glass furnace. By the setscrew carrying the linkage block to rotate, the linkage block carries the connecting column to rotate, which can make the setscrew achieve pressing and rolling, realize linkage rotation, reduce the contact friction, and avoid damaging the rolling part of the glass furnace.

[0016] 2. The present utility model adopts a guiding mechanism. The socket support block supports the connecting block, and the connecting block supports the guide sliding rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0025] As shown in the attached Figures 1-5 For the rolling automatic screw jack mechanism of the glass furnace shown, a screw jack rotating mechanism is provided on the rolling automatic screw jack mechanism of the glass furnace. The setting of the screw jack rotating mechanism can enable the linkage block 9 to carry the connecting column 8 to rotate, enable the screw jack 5 to achieve pressing and rolling, realize linkage rotation, reduce the friction of contact, avoid damaging the rolling parts of the glass furnace. The specific structural setting of the screw jack rotating mechanism is as follows.

[0026] In this technical solution, as shown in the attached Figures 1-3 One end of the support shaft 2 is fixedly installed with a screw jack rotating mechanism; the screw jack rotating mechanism includes a push column 3 fixedly installed at one end of the support shaft 2, and a push rod 4 is welded to one end of the push column 3. A screw jack 5 is provided on one side of the push rod 4, and a guiding sliding ring 6 is fixedly connected to the outer wall of the push rod 4; a limiting sliding column 7 is slidably connected to the inner wall of the guiding sliding ring 6. A connecting column 8 is welded to one end of the limiting sliding column 7, and a linkage block 9 is installed at one end of the connecting column 8.

The center point of the push column 3 and the center point of the screw jack 5 are on the same horizontal line, and both the screw jack 5 and the push rod 4 are made of stainless steel.

[0027] In this technical solution, as shown in the attached Figures 1-2 A limiting sliding ring 10 is fixedly connected to the outer wall of the connecting column 8, and the limiting sliding ring 10 is slidably connected to the guiding sliding ring 6. The vertical cross-sectional shape of the limiting sliding ring 10 is circular, so as to facilitate the connecting column 8 to carry the limiting sliding ring 10 to rotate.

The tip of the set screw 5 presses against the rolling part of the glass furnace. An extrusion friction force is generated through the extrusion of the set screw 5. When the rolling part of the glass furnace rotates, the set screw 5 carries the linkage block 9 to rotate. The linkage block 9 carries the connecting column 8 to rotate. The connecting column 8 drives the limiting sliding column 7 to rotate along the inner wall of the guiding sliding ring 6.

[0032] When this embodiment is in use, the support plate 20 can be fixed on the platform through bolts. The socket support block 13 is supported by the support plate 20. The connecting block 14 is supported by the socket support block 13. The guiding sliding rod 15 is supported by the connecting block 14. And when the socket block 1 moves rightward, the socket block 1 carries the sliding block 19 to move rightward along the outer wall of the sliding rail 18. At the same time, the sliding sleeve block 17 moves rightward along the outer wall of the sliding rail 18. And the sliding sleeve block 17 carries the two socket sliders 16 to move rightward. The socket slider 16 moves rightward along the outer wall of the guiding sliding rod 15, ensuring that the sliding sleeve block 17 and the socket block 1 can be guided to move rightward along the specified path.
