Description

Technical Field

[0001] This utility model relates to the field of ingot mold insulation board installation technology, specifically an auxiliary device for insulation board installation. Background Technology

[0002] Currently, in the steel casting process, insulated risers assembled with insulating plates are used in the ingot mold, which has become an effective means to improve the quality of steel ingots and increase the billet yield. The function of the riser is to provide additional molten metal to the steel ingot during the solidification and shrinkage of the molten metal to fill the defects caused by shrinkage porosity and shrinkage cavities.

[0003] However, in the actual installation process of insulation boards, the large weight and number of insulation boards often make the installation difficult, requiring multiple people to cooperate in the installation or resulting in improper installation. Improper installation of insulation boards can lead to the collapse of insulation boards or flash on the ingot risers, thereby causing the entire furnace to be scrapped or cracks to appear on the surface of the ingots. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for installing insulation panels, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for installing insulation panels, wherein the insulation panels are installed on the upper inner wall of the ingot mold, and the number of insulation panels is the same as the number of inner walls of the ingot mold. The auxiliary device includes a positioning frame and a clamping mechanism. When it is necessary to assist in the installation of the insulation panels, the positioning frame is located at the port of the ingot mold, and the number of clamping mechanisms is the same as the number of insulation panels. The clamping mechanism is installed on the positioning frame, and its other end forms a support mechanism for abutting against the insulation panel or ingot mold to be installed.

[0006] Based on the above technical features, this utility model, by installing one end of the clamping mechanism on the positioning frame and the other end abutting against the insulation board or ingot mold to be installed through the support mechanism, avoids the collapse of the insulation board and greatly improves the installation efficiency of the insulation board. In actual use, the installation and adjustment of the insulation board can be achieved by a single person, which greatly reduces the intensity of manual labor.

[0007] Preferably, in this technical solution, the clamping mechanism includes a support rod, wherein the positioning frame is an internally hollow annular structure, the axis of the annular structure extends along a first direction, and the positioning frame has multiple slots penetrating its wall thickness; in each clamping mechanism, the first end of the support rod extends into the interior of the annular structure through the corresponding slot, and the second end of the support rod is provided with the support mechanism; the slot is used to cooperate with the support rod to provide a supporting force for the support rod away from the annular structure along the extension direction of the support rod, and the extension direction of the support rod is perpendicular to the first direction.

[0008] Based on the above technical features, the positioning frame can insert the support rod into the corresponding slot according to the number of inner walls of the ingot mold (i.e., the number of sides at the ingot mold port), and after adjusting the length, it can be fixed with a locking nut. When the insulation board is installed, the support rod can be abutted against the insulation board through the support mechanism. The above-mentioned auxiliary device is not only simple in structure and low in manufacturing cost, but also has a significant effect.

[0009] Preferably, in this technical solution, the support rod is a threaded rod, wherein the tightening mechanism further includes a locking nut corresponding to each support rod. The locking nut is threadedly engaged with the support rod and located on the outside of the annular structure, for abutting against the outer surface of the annular structure to provide a supporting force away from the annular structure along the extension direction of the support rod; or, each slot on the positioning frame is a threaded hole, which can be threadedly connected to the first end of the support rod to provide a supporting force away from the annular structure along the extension direction of the support rod; or, each slot on the positioning frame is provided with a locking nut, which is used to threadly engage with the support rod when the first end of the support rod passes through the slot to provide a supporting force away from the annular structure along the extension direction of the support rod.

[0010] Based on the above technical features, this utility model has multiple implementation methods for auxiliary installation of insulation panels, including inserting the support rod into the slot and adjusting its length before tightening the lock nut (i.e., the lock nut abuts against the outer surface of the positioning frame), inserting the support rod into the threaded slot and turning the support rod to adjust its length, welding the lock nut to the slot, and passing the support rod through the slot and the lock nut and turning the support rod to adjust its length. All three implementation methods can provide the support rod with a supporting force away from the annular structure along the extension direction of the support rod, so that the support rod has sufficient supporting force to abut against the insulation panel or ingot mold to be installed.

[0011] Preferably, in this technical solution, the support mechanism includes a support plate connected to the second end of the support rod. The surface of the support plate away from the positioning frame forms a support surface for abutting against the heat insulation plate or the ingot mold, and the support surface is perpendicular to the support rod. More preferably, the support plate is fixedly connected to the support rod. Alternatively, the support plate is pivotally connected to the support rod so that the support rod can rotate around its own axis and cooperate with the support plate.

[0012] Based on the above technical features, during the installation of the insulation board, the support rod contacts the insulation board or the inner wall of the ingot mold through the support plate, which can effectively utilize the support surface of the support plate to increase the stress area, improve structural stability, and prevent the insulation board from collapsing.

[0013] In this technical solution, preferably, the positioning frame is a ring-shaped structure, and the plurality of slots are evenly distributed around the circumference of the ring-shaped structure.

[0014] Based on the above technical features, the auxiliary device in this utility model can install the insulation board by inserting a support rod into the slot in the corresponding direction to abut against the insulation board, according to the number and direction of the insulation board installation. It can be applied to ingot molds with different number of port sides (i.e., the number of inner walls).

[0015] Preferably, in this technical solution, the clamping mechanism includes a driving device and a piston rod, wherein the positioning frame is a plate-shaped structure, the driving device is fixedly mounted on the positioning frame, and the piston rod is telescopically mounted on the driving device. When it is necessary to assist in the installation of the insulation board, the driving device can drive the piston rod to move so that the end of the piston rod opposite to the driving device abuts against the insulation board or ingot mold to be installed; more preferably, the driving device is a loading hydraulic cylinder or a loading motor.

[0016] In this preferred embodiment, the jacking mechanism includes a handwheel, a reducer, a worm gear mechanism, and a slide bar. The positioning frame is a plate-shaped structure. The handwheel and the reducer are mounted on the positioning frame. The handwheel is connected to the reducer through the worm gear mechanism. When it is necessary to assist in the installation of the insulation plate, rotating the handwheel drives the slide bar to move so that the end of the slide bar opposite to the handwheel abuts against the insulation plate or ingot mold to be installed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0024] Before understanding this utility model, it is important to understand that the heat insulation plate 5 is installed on the inner wall of the upper end of the ingot mold, and the number of heat insulation plates 5 is the same as the number of inner walls of the ingot mold. The riser is formed by the heat insulation plate 5 installed on the inner wall of the ingot mold. Therefore, the cooling rate of the molten metal at the riser position is often significantly extended, so that the steel ingot at the riser position has enough time to undergo feeding treatment during casting, so as to provide additional molten metal to fill the defects caused by shrinkage porosity and shrinkage cavities in the steel ingot.

[0025] like Figure 1 and Figure 2 As shown, this utility model provides an auxiliary device for installing insulation panels. The auxiliary device includes a positioning frame 1 and a clamping mechanism. When it is necessary to assist in the installation of the insulation panel 5, the positioning frame 1 is located at the port of the ingot mold. The number of clamping mechanisms is the same as the number of insulation panels 5. The clamping mechanism is installed on the positioning frame 1, and the other end forms a support mechanism for abutting against the insulation panel 5 or the ingot mold to be installed.

[0026] Example 1:

[0027] The clamping mechanism includes a support rod 2, wherein the positioning frame 1 is an internally hollow ring structure, the axis of the ring structure extends along a first direction, and the positioning frame 1 has multiple slots that penetrate its wall thickness.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the positioning frame 1 is a ring-shaped structure with multiple slots evenly distributed around the circumference of the ring-shaped structure. By evenly opening multiple slots in the circumference of the positioning frame 1, the number of slots is equal to or greater than the number of support rods 2, so that the auxiliary device can be installed according to the number and installation direction of the insulation plates 5. By inserting the support rods 2 into the slots in the corresponding directions to abut against the insulation plates 5 and installing the insulation plates 5, it can be applied to ingot molds with different number of port sides (i.e., the number of inner walls).

[0029] In each clamping mechanism, the first end of the support rod 2 extends into the interior of the annular structure through the corresponding slot, and the second end of the support rod 2 is provided with a support mechanism; the slot is used to cooperate with the support rod 2 to provide the support rod 2 with a support force away from the annular structure along the extension direction of the support rod 2, and the extension direction of the support rod 2 is perpendicular to the first direction.

[0030] Furthermore, the support mechanism includes a support plate 4, which is connected to the second end of the support rod 2. The surface of the support plate 4 away from the positioning frame 1 forms a support surface for abutting against the heat insulation plate 5 or the ingot mold. The support surface is perpendicular to the support rod 2.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the port at the upper end of the ingot mold is rectangular, and there are four inner walls. Four heat insulation plates 5 need to be prepared and installed. The number of support rods 2, support plates 4 and locking nuts 3 are matched one by one, and there are four of them.

[0032] The support rod 2 is a threaded rod, and the tightening mechanism also includes a locking nut 3 corresponding to each support rod 2. The locking nut 3 is threadedly engaged with the support rod 2 and is located on the outside of the annular structure. It is used to abut against the outer surface of the annular structure to provide a supporting force away from the annular structure along the extension direction of the support rod 2. Preferably, the support rod 2 is fixedly connected to the support plate 4.

[0033] The specific working principle is as follows: Before installing the insulation plate 5, place the entire auxiliary device at the riser, adjust the length of the support rod 2, and tighten the locking nut 3 so that the support rod 2 in each direction abuts against the inner wall of the ingot mold through the support plate 4. Then install the insulation plate 5. Specifically, to install the upper insulation plate 5, loosen the corresponding upper locking nut 3 and adjust the length of the upper support rod 2 (which can be expressed as the length of the support rod extending into the inner hole of the positioning frame) so that the support rod 2 abuts against the upper insulation plate 5 to be installed through the support plate 4. To install the lower insulation plate 5, loosen the corresponding lower locking nut 3 and adjust the length of the lower support rod 2 so that the support rod 2 abuts against the lower insulation plate 5 to be installed through the support plate 4. Then install the left and right insulation plates 5 in sequence.

[0034] Example 2:

[0035] The support rod 2 is a threaded rod. Unlike embodiment 1, each slot on the positioning frame 1 is a threaded hole, which can be threadedly connected to the first end of the support rod 2 to provide support force away from the annular structure along the extension direction of the support rod 2. Preferably, the support rod 2 is pivotally connected to the support plate 4, that is, the support rod can rotate relative to the support plate.

[0036] The specific working principle is as follows: Before installing the insulation plate 5, the entire auxiliary device is placed at the riser. The support rod 2 is screwed on so that it abuts against the inner wall of the mold through the support plate 4. Then the insulation plate 5 is installed. Specifically, to install the upper insulation plate 5, the upper support rod 2 is screwed on and the length of the upper support rod 2 is adjusted so that it abuts against the upper insulation plate 5 to be installed through the support plate 4. To install the lower insulation plate 5, the lower support rod 2 is screwed on and the length of the lower support rod 2 is adjusted so that it abuts against the lower insulation plate 5 to be installed through the support plate 4. Then the left and right insulation plates 5 are installed in sequence.

[0037] Example 3:

[0038] The support rod 2 is a threaded rod. Unlike embodiments 1 and 2, each slot on the positioning frame 1 is provided with a locking nut 3. The locking nut 3 is welded to the slot and is used to engage with the support rod 2 threadedly when the first end of the support rod 2 passes through the slot, so as to provide a supporting force away from the annular structure along the extension direction of the support rod 2. Preferably, the support rod 2 is pivotally connected to the support plate 4.

[0039] The specific working principle is as follows: Before installing the insulation plate 5, the entire auxiliary device is placed at the riser. The support rod 2 is screwed on so that it abuts against the inner wall of the mold through the support plate 4. Then the insulation plate 5 is installed. Specifically, to install the upper insulation plate 5, the upper support rod 2 is screwed on and the length of the upper support rod 2 is adjusted so that it abuts against the upper insulation plate 5 to be installed through the support plate 4. To install the lower insulation plate 5, the lower support rod 2 is screwed on and the length of the lower support rod 2 is adjusted so that it abuts against the lower insulation plate 5 to be installed through the support plate 4. Then the left and right insulation plates 5 are installed in sequence.

[0040] Example 4:

[0041] The clamping mechanism includes a drive unit and a piston rod. The positioning frame 1 is a plate-like structure. The drive unit is fixedly mounted on the positioning frame 1, and the piston rod is telescopically mounted on the drive unit. When it is necessary to assist in the installation of the insulation plate 5, the drive unit can drive the piston rod to move so that the end of the piston rod opposite to the drive unit abuts against the insulation plate 5 or the ingot mold to be installed. The drive unit can be a loading hydraulic cylinder or a loading motor.

[0042] The specific working principle is as follows: Taking the ingot mold shown in Example 1 as an example, before installing the insulation plate 5, the entire set of auxiliary devices is placed at the riser. The piston rod is driven by the driving device, and the piston rod abuts against the inner wall of the ingot mold through the support mechanism. Then the insulation plate 5 is installed. Specifically, to install the upper insulation plate 5, the upper piston rod is driven by the upper driving mechanism, and the piston rod abuts against the upper insulation plate 5 to be installed through the support mechanism. To install the lower insulation plate 5, the lower piston rod is driven by the lower driving mechanism, and the piston rod abuts against the lower insulation plate 5 to be installed through the support mechanism. Then the left and right insulation plates 5 are installed in sequence.

[0043] Example 5:

[0044] The jacking mechanism includes a handwheel, a reducer, a worm gear mechanism, and a slide bar. The positioning frame 1 is a plate-shaped structure. The handwheel and the reducer are mounted on the positioning frame 1. The handwheel is connected to the reducer through the worm gear mechanism. When it is necessary to assist in the installation of the insulation plate 5, the handwheel is rotated to drive the slide bar to move so that the end of the slide bar opposite to the handwheel abuts against the insulation plate 5 or the ingot mold to be installed.

[0045] The specific working principle is as follows: Taking the ingot mold shown in Example 1 as an example, before installing the insulation plate 5, the entire set of auxiliary devices is placed at the riser. The sliding rod is moved by rotating the handwheel and abuts against the inner wall of the ingot mold through the support mechanism. Then the insulation plate 5 is installed. Specifically, to install the upper insulation plate 5, the upper handwheel is rotated to drive the upper sliding rod, so that the sliding rod abuts against the upper insulation plate 5 to be installed through the support mechanism. To install the lower insulation plate 5, the lower handwheel is rotated to drive the lower sliding rod, so that the sliding rod abuts against the lower insulation plate 5 to be installed through the support mechanism. Then the left and right insulation plates 5 are installed in sequence.
