Description

Technical Field

[0001] This utility model relates to the field of zirconia fiberboard production equipment and material transfer and transportation technology, specifically to a loading trolley for high-temperature sintering of zirconia fiberboard. Background Technology

[0002] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] High-temperature sintering is the core step in the production of zirconia fiberboard, and this process must be carried out in a sintering furnace. The loading process is a crucial step connecting the preceding forming process and the high-temperature sintering process. Currently, the industry mainly uses manual loading, fixed-height trolleys, and simple lifting devices.

[0004] Fixed-height trolleys or manual operation can only barely serve sintering furnaces of a specific height, and cannot adapt to sintering furnaces of varying heights. Loading and unloading taller billets requires operators to work at height, posing safety hazards. Alternatively, using long-handled tools to push billets over long distances results in extremely poor positioning accuracy, easily leading to misalignment or scratch damage. Simultaneously, it reduces work efficiency, significantly extending furnace door opening time, which exacerbates heat loss and energy waste.

[0005] Most simple lifting platforms still rely on auxiliary facilities and cannot actively extend into the depths of the furnace, so the billet still needs to be operated manually or with the assistance of auxiliary tools.

[0006] Therefore, it is necessary to study a charging trolley specifically designed for high-temperature sintering of zirconia fiberboard. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a loading trolley for high-temperature sintering of zirconia fiberboard. By integrating a high-temperature adaptable working platform and lifting, moving, loading, or towing functions, it solves the problem of adaptability to different sintering furnace heights, achieves precise delivery and removal of billets from the sintering furnace, reduces operational risks, and improves production efficiency and quality.

Detailed Implementation

[0029] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Figures 1 to 2 A loading trolley for high-temperature sintering of zirconia fiberboard is presented, including a base frame 100, a pusher frame 800 at one end of the base frame 100, a traveling wheel 110 on the base frame 100, a top frame 400 above the base frame 100, and a lifting hinge frame for lifting and lowering installed between the base frame 100 and the top frame 400.

[0031] The specific structure of the lifting hinge frame is as follows: it includes a pair of hinge arms 200 and a pair of sliding arms 300 arranged in an "X" shape, and the hinge arms 200 and sliding arms 300 are hinged together by a hinge rod 230.

[0032] The lower end of the hinge arm 200 is hinged to the base frame 100 via the lower hinge shaft 210, and the upper end of the hinge arm 200 is hinged to the top frame 400 via the upper hinge shaft 220.

[0033] The upper and lower ends of the sliding arm 300 are provided with corresponding sliders, and the top frame 400 and the bottom frame 100 are provided with sliding grooves that are adapted to the sliders.

[0034] A telescopic cylinder 240 is installed between the lower hinge shaft 210 and the hinge rod 230. The telescopic cylinder 240 drives the top frame 400 to rise and fall by driving the lifting hinge frame.

[0035] The lifting process of the top frame 400 is as follows: When the telescopic cylinder 240 begins to extend or retract, it drives the hinge rod 230 to move upward or downward in the vertical direction. At the same time, the hinge arm 200 rotates around the upper hinge shaft 220 and the lower hinge shaft 210, and the upper and lower ends of the sliding arm 300 begin to slide along the corresponding slide grooves.

[0036] The telescopic cylinder 240 can be automatically controlled or manually controlled. When it is manually controlled, the base frame 100 is equipped with a foot switch 241 for the telescopic cylinder 240.

[0037] The top frame 400 is provided with a worktable 410, a lead screw 500 and a guide rail 511 are installed in the middle of the worktable 410, a movable stage 510 is installed on the lead screw 500 and the guide rail 511, an operating rod 600 is installed on the movable stage 510, and a fixing component is provided at the end of the operating rod 600. The fixing component is used to connect to the tray that holds the zirconia fiber blank.

[0038] Two rows of high-temperature resistant rollers are provided on both sides of the lead screw 500 and guide rail 511. Since the sintering process needs to be carried out in an environment of 1800℃ to 2500℃, the temperature of the sintered zirconia fiber preform and its tray (and graphite pad) is very high. Therefore, the rollers should be able to adapt to the high temperature and the corresponding deformation caused by the large temperature difference. Thus, the rollers in this application are high-temperature resistant rollers, where "high temperature" refers to a temperature between 1800℃ and 2500℃. In this embodiment, the high-temperature resistant rollers are metal rollers and are installed on the corresponding metal roller frame 710.

[0039] In order to adapt to the impact of deformation caused by large temperature differences on assembly, in this embodiment, the roller frame 710 is provided with several pairs of mounting slots 711. The high-temperature resistant roller is placed in the mounting slots 711 through the mounting shaft. This open installation can adapt to the lifting and lowering of the work platform and can better adapt to the adverse effects of deformation.

[0040] The fixing component can be a snap-fit ​​component, a threaded fixing component, or a pin 610 component. This embodiment uses the pin 610 component as an example. The pin 610 component includes a pin 610 and a socket adapted to be formed on the operating lever 600 and the tray. During use, simply align the operating lever 600 with the socket on the tray, insert the pin 610 to fix it, and then perform moving loading or dragging unloading operations. The operation is simple and highly reliable.

[0041] The operating lever 600 is detachably mounted on the mobile platform 510 via the base 620, facilitating disassembly. After disassembling the operating lever 600, other transportation functions can be performed, giving the trolley a multi-functional feature. This also makes the trolley easy to replace and maintain, expands its application scenarios, and enhances the flexibility of equipment use.

[0042] The trolley is equipped with a moving table 510 consisting of a lead screw 500 and a guide rail 511. Together with the operating lever 600 and the fixing components, it can achieve precise positioning and stable transport of the billet pallet, avoid misalignment, scratching and other problems, and improve loading efficiency and process stability.

[0043] To further facilitate fine-tuning of the operating lever 600, the base 620 is provided with an elongated adjustment and fixing hole 621.
