Description

Technical Field

[0001] This utility model relates to the field of steel plate production technology, and in particular, to a movable roller device for a heat treatment furnace. Background Technology

[0002] In modern industrial production, heat treatment furnaces are crucial equipment for heat-treating metallic materials. During heat treatment, steel plates and other metallic materials undergo heating, holding, and cooling at high temperatures to improve their properties. However, efficiently and stably receiving and transporting heat-treated steel plates at the furnace discharge stage has always been a significant challenge affecting production efficiency and product quality. Traditional heat treatment furnace discharge methods typically employ fixed roller structures to receive steel plates. However, when receiving steel plates from the furnace, the large gap between the rollers and the furnace's rollers makes it easy for the steel plates to fall off the rollers or collapse, affecting normal transport. This is especially true for steel plates thinner than 10mm, which are more flexible and prone to collapsing and falling off the rollers. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a movable roller device for a heat treatment furnace.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A movable roller device for a heat treatment furnace includes: a base with an upper mounting surface, the mounting surface having a slide rail extending along a preset direction; a sliding table having a receiving state and a retracted state, the bottom having a groove adapted to the slide rail for slidable mounting on the slide rail; a sliding drive mechanism for driving the sliding table to reciprocate along the preset direction to switch between the receiving state and the retracted state; a receiving roller rotatably mounted on the sliding table along its own axis; the receiving roller on the sliding table in the receiving state extends out of the mounting surface; the receiving roller on the sliding table in the retracted state is closer to the base than in the receiving state.

[0006] Furthermore, the sliding table is provided with a slide bar, the slide groove is formed on the slide bar, and multiple slide bars and slide rails are provided and arranged in the left-right direction.

[0007] Furthermore, the cross-sectional profiles of both the groove and the rail are dovetail-shaped, wider at the top and narrower at the bottom.

[0008] Furthermore, the bottom of the sliding table is provided with a connecting lug, and the sliding drive mechanism has a telescopic rod that can extend and retract. The outer end of the telescopic rod and the connecting lug are provided with corresponding holes for connection by a pin.

[0009] Furthermore, a lifting platform is installed on the sliding platform, and the lifting platform can move up and down relative to the sliding platform and be fixed; the receiving roller is rotatably installed on the lifting platform.

[0010] Furthermore, the sliding table is provided with a vertically extending positioning cylinder, and the bottom of the lifting table is provided with a lifting column embedded in the positioning cylinder. The outer peripheral wall of the positioning cylinder is threaded with a set screw to tighten the lifting column embedded in the positioning cylinder.

[0011] Furthermore, the lifting column is provided with a positioning slot on one side corresponding to the set screw, and the positioning slots are arranged vertically, with one positioning slot inserted into the inner end of the set screw.

[0012] Furthermore, the lifting column and the positioning cylinder are spaced apart on the left and right, the sliding table is provided with a vertically extending support cylinder, and the positioning cylinder is located on the left and right sides of the support cylinder; the bottom of the lifting table is provided with a threaded column, and a nut is threadedly connected to the threaded column.

[0034] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a movable roller device for a heat treatment furnace, comprising a base 100, a sliding table 200, a sliding drive mechanism 300, and a receiving roller 400.

[0035] The base 100 has a mounting surface 110 at its upper end, and the mounting surface 110 has a slide rail 120 extending along a preset direction. The preset direction is... Figure 1 The front and back horizontal directions in the middle.

[0036] The sliding table 200 has a receiving state and a retracted state. The bottom of the sliding table 200 is provided with a sliding groove 210 that is adapted to the slide rail 120 so that it can be slidably installed on the slide rail 120.

[0037] The sliding drive mechanism 300 is used to drive the sliding table 200 to slide back and forth in a preset direction to switch between the receiving state and the shrinking state.

[0038] The receiving roller 400 is rotatably mounted on the sliding table 200 along its own axis; the axis of the receiving roller 400 is horizontal in the left-right direction. In the receiving state, the receiving roller 400 on the sliding table 200 extends out of the mounting surface 110 to be inserted into the heat treatment furnace to receive the steel plate output from the heat treatment furnace; in the retracted state, the receiving roller 400 on the sliding table 200 is closer to the base 100 than in the receiving state, and the retracted receiving roller 400 is withdrawn.

[0039] In a preferred embodiment of this utility model, a movable roller device for a heat treatment furnace is provided. The sliding table 200 can reciprocate along a preset direction under the drive of the sliding drive mechanism 300, thereby switching between a receiving state and a retracted state. In the receiving state, the receiving roller 400 on the sliding table 200 extends out of the mounting surface 110 and can reach into the heat treatment furnace, greatly reducing the distance between the roller and the rollers inside the furnace. This effectively prevents steel plates from falling off the rollers or collapsing, especially for soft steel plates with a thickness of less than 10mm, providing more stable and reliable support and ensuring normal transport of the steel plates. In the retracted state, the receiving roller 400 on the sliding table 200 is closer to the base 100, providing convenient space for subsequent transport and processing of the steel plates. Furthermore, the retracted receiving roller 400 can retract and exit the heat treatment furnace without affecting the closure of the furnace door.

[0040] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the sliding table 200 is provided with a slide bar 220, and a slide groove 210 is formed on the slide bar 220. Multiple slide bars 220 and slide rails 120 are provided and arranged in the left and right direction, thereby realizing multi-position sliding guide limit and improving sliding stability. The length of the slide bar 220 is greater than that of the sliding table 200 and protrudes a section from the rear side of the sliding table 200. This ensures that even after the sliding table 200 extends all or part of its length beyond the mounting surface 110, the slide bar 220 still cooperates with the slide rail 120 and does not detach from the slide rail 120, thus making the component installation stable.

[0041] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the cross-sectional profiles of the slide groove 210 and the slide rail 120 are both dovetail-shaped with a wider top and a narrower bottom, which prevents the sliding table 200 from moving upward and disengaging from the slide rail 120, thus providing a vertical limit for the sliding table 200. This ensures that the sliding table 200 will not tip over after extending all or part of its length beyond the mounting surface 110.

[0042] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the bottom of the sliding table 200 is provided with a connecting ear 230, and the sliding drive mechanism 300 has a telescopic rod 310 that can extend and retract. The outer end of the telescopic rod 310 and the connecting ear 230 are provided with corresponding holes for connection by a pin. The sliding table 200 is raised by the slide rail 120 so that the connecting ear 230 can be provided at its bottom to facilitate connection with the telescopic rod 310, thereby realizing the connection between the sliding table 200 and the sliding drive mechanism 300. It can be understood that the sliding drive mechanism 300 can be a hydraulic telescopic cylinder.

[0043] Reference Figure 2 and Figure 3In some embodiments of this utility model, a lifting platform 240 is installed on the sliding table 200. The lifting platform 240 can move up and down relative to the sliding table 200 and be fixed. The receiving roller 400 is rotatably mounted on the lifting platform 240, and the receiving roller 400 is indirectly mounted on the sliding table 200 through the lifting platform 240. The height of the receiving roller 400 can be adjusted by the lifting movement of the lifting platform 240, thereby allowing for adaptive adjustment according to actual conditions and improving the adaptability of the device.

[0044] Of course, in some other embodiments, the lifting platform 240 may not be provided, and the receiving roller 400 may be directly installed on the sliding platform 200.

[0045] Reference Figure 2 and Figure 3 In a further embodiment of this utility model, the sliding table 200 is provided with a vertically extending positioning cylinder 250, and the bottom of the lifting table 240 is provided with a lifting column 241 embedded in the positioning cylinder 250. The outer peripheral wall of the positioning cylinder 250 is threaded with a set screw 251 to tighten the lifting column 241 embedded in the positioning cylinder 250. The positioning cylinder 250 is provided with an insertion hole with an upper opening. The lifting column 241 is inserted into the insertion hole of the positioning cylinder 250 to achieve lifting guidance. The upper peripheral wall of the positioning cylinder 250 is provided with a threaded hole for the set screw 251 to be threadedly connected, thereby fixing the lifting column 241 by the set screw 251.

[0046] Reference Figure 3 and Figure 5 In a further embodiment of this utility model, the lifting column 241 is provided with a positioning slot 242 on one side corresponding to the set screw 251. The positioning slots 242 are arranged vertically. The inner end of the set screw 251 is inserted into one of the positioning slots 242. By inserting the set screw 251 into the positioning slots 242 at different heights, the lifting column 241 is fixed at different heights. Moreover, the insertion of the set screw 251 into the positioning slot 242 makes the height of the lifting column 241 more stable than using only friction.

[0047] Reference Figure 3 and Figure 5In a further embodiment of this utility model, multiple sets of lifting columns 241 and positioning cylinders 250 are provided and spaced apart on the left and right sides, thereby providing multi-position lifting guidance and fixation, and improving the stability of the device. The sliding table 200 is provided with a vertically extending support cylinder 260, and the positioning cylinders 250 are located on the left and right sides of the support cylinder 260; the bottom of the lifting table 240 is provided with a threaded column 243, and a nut 244 is threadedly connected to the threaded column 243; the support cylinder 260 is provided with a central hole with an upper opening, the bottom of the threaded column 243 is inserted into the central hole of the support cylinder 260, the outer diameter of the nut 244 is larger than the central hole, and the nut 244 abuts against the upper end face of the support cylinder 260, thereby transferring the load to the support cylinder 260 through the nut 244, avoiding the concentration of gravity load on the set screw 251, and improving installation stability.

[0048] Reference Figure 4 In a further embodiment of this utility model, the lifting platform 240 is provided with support seats 245 at both ends, and pressure rings 270 are connected to the support seats 245. Bearings 280 are installed between the support seats 245 and the pressure rings 270. The receiving roller 400 is provided with journals 410 at both ends, and the journals 410 are inserted into the inner rings of the bearings 280, thereby realizing the detachable installation of the receiving roller 400 and reducing rotational friction. The pressure rings 270 and the support seats 245 are provided with corresponding holes for connection and fixation by fasteners.

[0049] Reference Figure 4 In a further embodiment of this utility model, the lifting platform 240 is provided with an mounting plate 246 on one side of the receiving roller 400. A rotary drive mechanism 500 is mounted on the mounting plate 246, and the rotary output shaft of the rotary drive mechanism 500 is connected to the receiving roller 400. This enables the rotary drive of the receiving roller 400, thereby providing a certain conveying power to the steel plate during material receiving.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
