Description
Technical Field
[0001] This utility model relates to the field of feeding rack technology, specifically a detachable feeding rack for a high-temperature testing furnace. Background Technology
[0002] High-temperature testing furnaces for glass are core equipment for simulating extreme thermal environments. They provide a precise and controllable high-temperature environment for glass samples, with accurate and stable temperature control and excellent heat preservation performance. This ensures that performance tests of glass (such as thermal stability, softening point, crystallization behavior, etc.) can be conducted accurately at the set temperature. Among these tests, the test rack that supports the glass samples plays a crucial role. It must reliably support the samples at high temperatures inside the furnace, possess excellent temperature resistance and creep resistance, and minimize interference with the sample's heating state or test results.
[0003] The loading rack is fundamental to ensuring the reliability and validity of the entire testing process, but it still has certain problems: 1) Traditional methods require operators to manually push and pull the loading rack close to the high-temperature furnace opening, posing a serious risk of burns; 2) Due to the height difference between the furnace cavity and the ground, the loading rack is at risk of tipping over when entering and exiting the furnace cavity, and its transfer efficiency is low; 3) Traditional loading racks with casters can improve transfer efficiency, but high-temperature testing environments require expensive high-temperature resistant casters, which are prone to damage due to frequent use on the ground, increasing usage and maintenance costs. Therefore, in view of the above situation, there is an urgent need to develop a detachable loading rack for high-temperature testing furnaces to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content
[0004] The purpose of this invention is to provide a detachable feeding rack for a high-temperature testing furnace to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable feeding rack for a high-temperature testing furnace, comprising a testing furnace for conducting high-temperature tests on glass, a rack for carrying the glass to be tested, and a trolley for transporting the rack and pushing it into the testing furnace.
[0006] In practical use, the detachable structure enables separation of personnel and furnace operation. After the trolley is loaded with the placement rack outside the furnace, it is pushed into the test furnace as a whole, effectively avoiding the safety risks caused by operators directly contacting the high-temperature furnace body. At the same time, the trolley can quickly detach from the placement rack and return to the loading station for the next round of loading, significantly shortening the waiting time of the test furnace and improving equipment utilization and testing efficiency. In addition, the trolley itself avoids continuous high-temperature baking, extending its service life, while the dedicated placement rack ensures the stable bearing of the glass in the high-temperature environment. The overall structure optimizes the loading process, taking into account safety, efficiency and equipment reliability.
[0007] The trolley includes a base, a lifting and mounting frame on the base, and a sliding assembly that passes through one side of the support frame for pulling the placement rack.
[0008] A limiting groove is installed at the inner bottom of the supporting frame, and a limiting sleeve is inserted through the middle of the side wall of the supporting frame. The inner bottom of the supporting frame is flush with the inner bottom of the furnace cavity of the test furnace.
[0009] In practical use, the trolley's height is precisely adjusted via a height-adjustable support frame to ensure that its inner bottom is flush with the bottom of the test furnace cavity, enabling seamless and stable horizontal movement of the placement rack between the two. The limiting groove at the bottom of the support frame effectively constrains the displacement path of the placement rack, while the limiting sleeve in the middle of the side wall provides a stable sliding guide and support for the push-pull assembly, allowing the push-pull assembly to reliably pull the placement rack into or out of the test furnace. The entire structure works together to ensure precise positioning, smooth operation, and safe operation during the feeding process.
[0010] The rack is equipped with several shelves for placing the glass to be tested. The rack has casters at the four corners of its bottom. A crossbeam is installed on the side of the rack away from the test furnace, and a locking block that matches the push-pull assembly is installed on the crossbeam.
[0011] In practical use, the placement rack uses the four corner wheels at the bottom to cooperate with the limiting grooves of the trolley's supporting frame, achieving precise guidance and positioning of the placement rack within the supporting frame. At the same time, the wheels ensure that it can move independently within the testing furnace. The locking blocks on the crossbeam quickly connect with the trolley's push-pull assembly, allowing the push-pull assembly to reliably pull the entire placement rack smoothly in and out of the high-temperature furnace along the limiting sleeve slide rail. The multi-layered design of the shelves efficiently supports multiple sets of glass to be tested. The overall structure significantly improves the smoothness of material loading and ease of operation while ensuring the stability of high-temperature testing.
[0012] Preferably, the base is equipped with casters at the four corners of the bottom, and lifting columns for connecting the support frame are installed on the base.
[0013] In practical use, the four omnidirectional wheels at the bottom of the base enable the trolley to move flexibly in all directions, facilitating quick positioning in the laboratory environment; while the lifting column ensures that its inner bottom is always horizontally aligned with the bottom of the test furnace cavity by precisely adjusting the height of the supporting frame, providing a core guarantee for the smooth entry and exit of the placement rack.
[0014] Preferably, a push rod is installed on one side of the support frame, and sealing plates are installed on the sides of the support frame away from the test furnace.
[0015] In practical use, the push rods on the side of the support frame provide the operator with a fulcrum for applying force; while the sealing plates installed on multiple sides of the support frame away from the test furnace form a physical barrier, which not only blocks high-temperature radiation to protect the operation safety, but also prevents external debris from entering the equipment operating area. At the same time, together with the push-pull components and lifting columns, they enhance the overall rigidity and operational reliability of the trolley, further optimizing the safety and stability of the high-temperature feeding process.
[0016] Preferably, there are four moving wheels, all of which are made of high-temperature resistant material. The two moving wheels adjacent to the test furnace are omnidirectional moving wheels, and the two moving wheels away from the test furnace are directional wheels.
[0017] In practical use, four high-temperature resistant casters ensure stable operation of the placement rack within the high-temperature furnace cavity. Two omnidirectional casters closer to the test furnace provide flexibility for steering during entry, adapting to fine-tuning needs within the furnace space; the two directional casters further away maintain a straight-line trajectory, working in conjunction with the trolley's limiting grooves to prevent deviation. This modular design of the casters ensures controllability during precise alignment between the load-bearing frame and the furnace cavity guide rails, while their high-temperature resistance prevents wheel deformation and failure, significantly improving the reliability and smoothness of multi-layer glass transfer in high-temperature environments.
[0018] Preferably, the push-pull assembly includes an extension rod, a handle, a traction line, an inner shaft, a clamping seat, and a latch. The inner shaft is slidably inserted into the limiting sleeve. One end of the inner shaft located within the bearing frame is fixedly provided with a clamping seat. A latch adapted to the locking block is hinged to one side of the clamping seat. A torsion spring is installed between the latch and the clamping seat. The other end of the inner shaft is rotatably connected to an extension rod. A handle is installed at the end of the extension rod. A conduit a is fixedly provided on the outer wall of the extension rod. A conduit b is fixedly provided on the outer wall of the inner shaft. The traction line is sequentially inserted into conduit a and conduit b. The two ends of the traction line are respectively connected to the handle and the latch.
[0019] In practical use, the push-pull assembly achieves precise guidance through the sliding of the inner shaft within the limiting sleeve. The torsion spring keeps the latch in a normally closed position, ensuring automatic locking with the block of the placement frame beam. When the operator holds the handle and applies force through the extension rod, the traction line transmits the tension through the secondary guides of line tubes a and b, driving the latch on the clamp to rotate around the hinge point, thereby releasing the latch. This structure allows the operator to reliably lock and separate the block even when away from the high-temperature furnace opening. Line tubes a and b are both compatible with the limiting sleeve, achieving radial positioning of the extension rod and the inner shaft and preventing their deflection. Holding the handle and pushing the extension rod axially can cause the inner shaft to displace axially from the limiting sleeve, significantly improving the safety, convenience, and accuracy of traction operation in high-temperature environments.
[0020] Compared with the prior art, this utility model provides a detachable feeding rack for a high-temperature testing furnace, which has the following advantages:
[0021] Through the collaborative innovation of a detachable trolley and a high-temperature resistant rack, the operation of separating personnel from the furnace during high-temperature testing is realized. The push-pull assembly allows the operator to be completely away from the high-temperature area, effectively improving testing safety. At the same time, it can significantly improve the efficiency of transportation and testing. The trolley's lifting and positioning and the rack's wheel set work together to ensure that the equipment is quickly and accurately docked. Combined with the detachable structure, the furnace body's idle time is minimized. The system systematically solves the reliability problem in high-temperature environments. The high-temperature resistant moving wheels and mechanical traction mechanism ensure the stable operation of key components under extreme conditions, avoiding equipment damage and safety hazards caused by traditional manual handling.

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.
[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0039] Example:
[0040] Please see Figures 1-13 This utility model provides a technical solution: a detachable feeding rack for a high-temperature testing furnace, including a testing furnace 30 for high-temperature testing of glass, a placement rack 20 for carrying the glass to be tested, and a trolley 10 for transporting the placement rack 20 and pushing it into the testing furnace 30.
[0041] In practical use, the detachable structure enables separation of personnel and furnace operation. After loading the placement rack 20 outside the furnace, the trolley 10 pushes the entire trolley into the test furnace 30, effectively avoiding the safety risks caused by operators directly contacting the high-temperature furnace body. At the same time, the trolley 10 can quickly detach from the placement rack 20 and return to the loading station for the next round of material feeding, significantly shortening the waiting time of the test furnace 30 and improving equipment utilization and testing efficiency. In addition, the trolley 10 itself avoids continuous high-temperature baking, extending its service life, while the dedicated placement rack 20 ensures the stable bearing of the glass in the high-temperature environment. The overall structure optimizes the material feeding process, taking into account safety, efficiency and equipment reliability.
[0042] The trolley 10 includes a base 110, a support frame 120 that can be lifted and mounted on the base 110, and a push-pull assembly 130 that can be slidably passed through one side of the support frame 120 for pulling the placement rack 20.
[0043] A limiting groove 123 is installed on the inner bottom of the supporting frame 120, and a limiting sleeve 124 is inserted through the middle of the side wall of the supporting frame 120. The inner bottom of the supporting frame 120 is flush with the inner bottom of the furnace cavity of the test furnace 30.
[0044] In practical use, the trolley 10 can be precisely adjusted in height through the liftable support frame 120 to ensure that its inner bottom is flush with the bottom of the furnace cavity of the test furnace 30, so as to achieve seamless and stable horizontal movement of the placement rack 20 between the two. The limiting groove 123 at the bottom of the support frame 120 effectively constrains the displacement path of the placement rack 20, while the limiting sleeve 124 in the middle of the side wall provides a stable sliding guide and support for the push-pull assembly 130, so that the push-pull assembly 130 can reliably pull the placement rack 20 into or out of the test furnace 30. The whole structure works together to ensure accurate positioning, smooth operation and safe operation during the feeding process.
[0045] The placement rack 20 is equipped with several shelves 210 for placing the glass to be tested. The four corners of the bottom of the placement rack 20 are equipped with casters 220. A crossbeam 230 is installed on the side of the placement rack 20 away from the test furnace 30. A locking block 240 that is compatible with the push-pull assembly 130 is installed on the crossbeam 230.
[0046] In practical use, the placement rack 20 uses the four corner casters 220 at the bottom to cooperate with the limiting grooves 123 of the trolley 10's supporting frame 120, so as to achieve precise guidance and positioning of the placement rack 20 within the supporting frame 120. At the same time, the casters 220 ensure that it can move independently within the test furnace 30. The locking block 240 on the crossbeam 230 quickly connects with the push-pull assembly 130 of the trolley 10, so that the push-pull assembly 130 can reliably pull the entire placement rack 20 smoothly into and out of the high-temperature furnace cavity along the sliding rail of the limiting sleeve 124. The multi-layered shelf 210 efficiently supports multiple sets of glass to be tested. The overall structure significantly improves the smoothness of material loading and the convenience of operation while ensuring the stability of high-temperature testing.
[0047] Preferably, casters 111 are installed at the four corners of the bottom of the base 110, and lifting columns 112 for connecting the support frame 120 are installed on the base 110.
[0048] In practical use, the casters 111 at the four corners of the base 110 enable the trolley 10 to move flexibly in all directions, making it easy to quickly position in the laboratory environment; while the lifting column 112 ensures that its inner bottom is always horizontally aligned with the bottom of the furnace cavity of the test furnace 30 by precisely adjusting the height of the support frame 120, providing a core guarantee for the smooth entry and exit of the placement rack 20.
[0049] Preferably, a push rod 121 is installed on one side of the support frame 120, and a sealing plate 122 is installed on the side of the support frame 120 away from the test furnace 30.
[0050] In practical use, the push rod 121 on the side of the support frame 120 provides the operator with a fulcrum for applying force; while the sealing plates 122 installed on multiple sides of the support frame 120 away from the test furnace 30 form a physical barrier, which not only blocks high-temperature radiation to protect the operation safety, but also prevents external debris from entering the equipment operating area. At the same time, together with the push-pull assembly 130 and the lifting column 112, it strengthens the overall rigidity and operational reliability of the trolley 10, and further optimizes the safety and stability of the high-temperature feeding process.
[0051] Preferably, there are four movable wheels 220. All movable wheels 220 are made of high temperature resistant material. Among them, the two movable wheels 220 adjacent to the test furnace 30 are omnidirectional movable wheels, and the two movable wheels 220 away from the test furnace 30 are directional wheels.
[0052] In practical use, four high-temperature resistant casters 220 ensure the stable operation of the placement rack 20 within the high-temperature furnace cavity. The two omnidirectional casters closer to the test furnace 30 provide flexibility for steering during furnace entry, adapting to the need for fine-tuning within the furnace space. The two directional casters further away from the furnace maintain a straight-line trajectory, working in conjunction with the limiting groove 123 of the trolley 10 to prevent deviation. This modular design of the casters ensures controllability during precise alignment between the placement rack 20 and the furnace cavity guide rails, while also preventing wheel deformation and failure due to their high-temperature resistance, significantly improving the reliability and operational smoothness of multi-layer glass transfer under high-temperature conditions.
[0053] Preferably, the push-pull assembly 130 includes an extension rod 131, a handle 132, a traction line 133, an inner shaft 134, a clamping seat 135, and a buckle 136. The inner shaft 134 is slidably inserted into the limiting sleeve 124. One end of the inner shaft 134 located within the bearing frame 120 is fixedly provided with the clamping seat 135. A buckle 136 adapted to the locking block 240 is hinged to one side of the clamping seat 135. A torsion spring is installed between the buckle 136 and the clamping seat 135. The other end of the inner shaft 134 is rotatably connected to the extension rod 131. The handle 132 is installed at the end of the extension rod 131. A conduit a1311 is fixedly provided on the outer wall of the extension rod 131. A conduit b1341 is fixedly provided on the outer wall of the inner shaft 134. The traction line 133 is sequentially inserted into the conduit a1311 and the conduit b1341. The two ends of the traction line 133 are respectively connected to the handle 132 and the buckle 136.
[0054] In practical use, the push-pull assembly 130 achieves precise guidance through the sliding of the inner shaft 134 within the limiting sleeve 124. The torsion spring keeps the latch 136 in a normally closed position, ensuring automatic locking with the locking block 240 of the crossbeam 230 of the display rack 20. When the operator holds the handle 132 and applies force through the extension rod 131, the traction line 133 transmits the pulling force through the secondary guides of the conduit a1311 and the conduit b1341, driving the latch 136 on the clamping seat 135 to rotate around the hinge point, thereby... Release buckle 136. This structure allows the operator to reliably lock and release the locking block 240 while away from the high-temperature furnace opening. Both conduit a1311 and conduit b1341 are adapted to the limiting sleeve 124 to achieve radial positioning of the extension rod 131 and the inner shaft 134, preventing them from deflecting. By holding the handle 132 and pushing the extension rod 131 axially, the inner shaft 134 can be displaced from the limiting sleeve 124 and moved axially, which significantly improves the safety, convenience and accuracy of traction operation in high-temperature environments.
[0055] Working principle: The operator first moves the rack 20, which is loaded with glass to be tested, to the front of the test furnace 30 using the casters 111 at the bottom of the trolley 10. The height of the support frame 120 is adjusted beforehand using the lifting column 112 so that its inner bottom is flush with the bottom of the furnace cavity. Then, the operator holds the handle 132 of the push-pull assembly 130 and pulls the traction line 133 to open the buckle 136. After the buckle 240 of the crossbeam 230 of the rack 20 is engaged, it is automatically locked by the torsion spring. The operator pushes the handle 132 to smoothly send the rack 20 into the furnace cavity through the limiting groove 123. The sealing plate 122 of the support frame 120 simultaneously seals the furnace opening for heat insulation. After locking is completed, the operator pulls the handle 132 to release the buckle 136, and the trolley 10 is removed from the furnace opening. After the test is completed, the trolley 10 is reconnected, and the rack 20 is pulled out for transfer and unloading.
