Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, specifically relating to an open frame and a roller device using the open frame. Background Technology

[0002] Continuous strip handling units often include various extrusion roller devices 100, such as pinch rollers, squeeze rollers, and coating machines. These devices use the squeezing action between the rollers 101 to either move the strip, remove liquid from its surface, or apply various coatings to it. The roller surfaces of these devices are prone to wear due to friction with the strip, thus requiring frequent replacement. Figure 1 To reduce strip production loss caused by online roller replacement 101, an offline roller replacement method is conventionally adopted. This means the equipment is located in the working position of the unit during operation, moved to the offline maintenance position during maintenance, and then moved back to the working position after maintenance is completed. It is common practice to arrange two sets of this type of equipment in parallel on the unit, allowing the two sets to alternate between the working and maintenance positions.

[0003] For roller-type equipment 100, an open frame is more convenient to enable frequent movement between the unit's working and maintenance positions; such as Figure 2 A commonly used open-type frame is formed by combining a cantilever frame 102 and a short frame 103. However, for the aforementioned extrusion roller equipment 100, the rollers 101 need to contact each other and extrude the strip during operation, and during maintenance, the upper and lower rollers 101 need to be far apart to form sufficient space. Due to the large extrusion pressure between the rollers during operation, the open-type frame is prone to deformation, which in turn leads to a large difference in extrusion pressure on both sides of the rollers 101, affecting the quality of strip steel production.

[0024] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] like Figures 3-6 This utility model embodiment provides an open-type rack, including:

[0027] The cantilever frame 11 includes an upright frame section 112 mounted on a frame foundation and a cantilever frame section 111 connected to the top of the upright frame section 112.

[0028] Short frame 12, which is located directly below the cantilever end of cantilever frame section 111 and has an opening gap between it and the cantilever end;

[0029] A frame connector and a drive mechanism are provided, the drive mechanism being disposed on the short frame 12, the frame connector being connected to the drive mechanism and having a connection position movable to connect with the cantilever frame section 111 and a standby position detached from the cantilever frame section 111.

[0030] The cantilever frame 11 is provided with an upper roller bearing seat mounting position for installing the upper roller bearing seat. There are generally two upper roller bearing seats, and the two ends of the upper roller 131 are respectively installed on the two upper roller bearing seats. Accordingly, there are two upper roller bearing seat mounting positions. The two upper roller bearing seat mounting positions can both be located in the cantilever frame section 111, or one can be located in the cantilever frame section 111 and the other can be located in the upright frame section 112.

[0031] Preferably, both the short frame 12 and the upright frame section 112 are provided with lower roller bearing seat mounting positions, and a lower roller lifting device is also provided on the frame base. The lower roller lifting device is arranged adjacent to at least one of the lower roller bearing seat mounting positions. The lower roller bearing seat mounting positions are used to install the lower roller bearing seats, that is, when the two lower roller bearing seats are respectively installed on the short frame 12 and the upright frame section 112; by setting the lower roller lifting device, the lower roller 132 can be driven to rise and fall. Therefore, the lower roller bearing seats can rise and fall relative to the short frame 12 and the upright frame section 112. Correspondingly, the lower roller bearing seats are movably mounted on the short frame 12 and the upright frame section 112, including but not limited to setting guide rails on the short frame 12 and the upright frame section 112. The guiding direction of the guide rails is parallel to the vertical, and the lower roller bearing seats are movably mounted on the corresponding guide rails. The guide rails constitute the lower roller bearing seat mounting positions. The aforementioned lower roller lifting device includes, but is not limited to, the use of hydraulic cylinders, pneumatic cylinders, etc.; preferably, driving devices are configured for each of the two lower roller bearing seats, that is, the lower roller lifting device includes two sets of lower roller lifting units, and the two sets of lower roller lifting units are respectively arranged adjacent to the mounting positions of the two lower roller bearing seats.

[0032] The aforementioned cantilever frame 11 and short frame 12 are combined to form an open frame. The frame connector is used to connect the short frame 12 with the cantilever frame section 111. Through this connection, the open frame can be transformed into a closed frame, solving the problems of large frame opening and large deformation, effectively improving the rigidity of the frame, and thus improving the working stability and reliability of the roller equipment.

[0033] The aforementioned frame connectors include, but are not limited to, hook plates 151, with a pressure plate on the cantilever frame section 111 suitable for being hooked by the hook plates 151. In another embodiment, the frame connectors may also be threaded connectors (threaded to the cantilever frame section 111), clamping components (e.g., gripping the cantilever frame section 111), etc.

[0034] Mounting the drive mechanism on the short frame 12 not only facilitates layout but, more importantly, ensures high operational reliability, allowing the drive load to be reliably transmitted to the foundation below via the short frame 12. In this design, the frame connector can be raised to connect with the cantilever frame section 111 and lowered to reset and separate from the cantilever frame section 111 via the drive mechanism.

[0035] In one embodiment, such as Figures 3-6 The driving mechanism includes a rotary telescopic cylinder 152, and the hook plate 151 is installed at the output end of the rotary telescopic cylinder 152; the rotary telescopic cylinder 152 is installed on the short frame 12, and the extension direction of the rotary telescopic cylinder 152 is upward.

[0036] The rotary telescopic cylinder 152 can drive the frame connector to rise, fall and rotate. The piston rod of the rotary telescopic cylinder 152 extends along a curve at a specific angle, that is, the piston rod extends and rotates at a specific angle at the same time. This method is especially suitable for the case where the frame connector uses a hook plate 151. It can avoid interference between the hook plate 151 fixed to the piston rod end of the rotary telescopic cylinder 152 and the cantilever frame section 111 when it rises and falls, and can hook the cantilever frame section 111 in one step.

[0037] The lifting stroke requirements of the frame connector can be directly met by the aforementioned rotary telescopic cylinder 152, in which case the rotary telescopic cylinder 152 can be directly installed on the short frame 12. However, as a preferred solution, such as Figures 3-6 The drive mechanism further includes a lifting drive cylinder 153, which is mounted on the short frame 12 and has a cylinder support 154 at its output end. The rotary telescopic cylinder 152 is mounted on the cylinder support 154. In this design, the combination of the lifting drive cylinder 153 and the rotary telescopic cylinder 152 effectively avoids interference between the hook plate 151 and the frame during the lifting and lowering process, resulting in higher reliability. This ensures that the hook plate 151 is away from the frame during lifting and lowering, and smoothly inserts into the cantilever frame section 111 for pressing connection or detaches from the cantilever frame section 111 after lifting and lowering.

[0038] The aforementioned lifting drive cylinder 153 and rotary telescopic cylinder 152 can each be a single-acting cylinder; or, the lifting drive cylinder 153 and the rotary telescopic cylinder 152 can be integrated into a double-acting cylinder, that is, a double-piston rod bidirectional hydraulic cylinder, with the two piston rods extending and retracting in opposite directions. This method can further simplify the structure of the drive mechanism and facilitate the layout of on-site equipment.

[0039] Furthermore, the open frame also includes a guide unit 155. The guide unit 155 and the lifting drive cylinder 153 are both arranged on the short frame 12. The cylinder support 154 is guided and cooperates with the guide unit 155. The guide unit 155 includes, but is not limited to, guiding methods such as slider-rail and guide shaft-guide sleeve. By setting the guide unit 155, the stability and reliability of the lifting of the frame connector can be improved.

[0040] In another embodiment, the above-mentioned drive mechanism can also be a combination of a lifting drive device and a rotary drive device. The lifting drive device can be a drive cylinder, and the rotary drive device can be a motor, etc. In this scheme, it is advisable to avoid the motor bearing axial force. For example, a transmission structure such as a motor + gear assembly can be used to drive the rotary seat.

[0041] The aforementioned short frame 12 and cantilever frame 11 can be directly installed on the workshop foundation or on a base. Optionally, such as Figures 3-6 The frame base includes a movable base 14, and the upright frame section 112 and the short frame 12 are both mounted on the movable base 14, so that the frame can be switched between the working position and the maintenance position, which facilitates the maintenance of the equipment using the frame.

[0042] Example 2

[0043] like Figures 3-6 The present invention also relates to a roller device, including a frame and working rollers arranged on the frame, wherein the frame is an open frame as provided in Embodiment 1 above.

[0044] When the roller equipment is put into production, the frame connector is in the connection position to achieve a rigid connection between the short frame 12 and the cantilever frame 11; when the roller equipment is maintained, the frame connector is in the standby position before relevant maintenance work is carried out.

[0045] Obviously, the switching of the workstation where the frame connector is located is achieved through the aforementioned drive mechanism. The specific structure and driving method of the drive mechanism have been described in the above embodiment one, and will not be repeated here.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
