Description

Technical Field

[0001] This invention belongs to the field of low-temperature resistance furnace technology, specifically relating to a trolley track for a low-temperature resistance furnace. Background Technology

[0002] Currently, most resistance furnaces use a sliding track design because the bottom of the furnace is lined with refractory material and heating belts. The track cannot be directly fixed inside the furnace; instead, it is fixed outside and designed as a telescopic track. It only enters the furnace to place the sheet metal for heating or removal when needed. Because this requires power and is used frequently, the failure rate is high, maintenance is cumbersome, and production efficiency is reduced. Furthermore, the existing track structure is simple, making it difficult to adjust the distance between the guide rails, and displacement during use can easily cause deviation. Guide rails connected by welding are often disposable, resulting in high operating costs. Summary of the Invention

[0003] In view of the problems mentioned in the background art above, the purpose of the present invention is to provide a trolley track for a low-temperature resistance furnace.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A trolley track for a low-temperature resistance furnace includes several intermediate track supports and two edge track supports fixed to the bottom of the furnace body. The longitudinal cross-section of both the intermediate and edge track supports is inverted T-shaped. Fixing holes are provided on both sides of each intermediate and edge track support. A heating element is installed between adjacent intermediate track supports. Each intermediate track support has a sliding groove, and each edge track support has several position adjustment holes fitted with locking screws. Two guide rails are placed on each of the intermediate and edge track supports, and each guide rail has sliding plates that match the sliding grooves. The guide rail is integrally connected to both ends with mating plates, and the mating plates are provided with mating holes. A T-shaped slide rail is integrally connected to the top of the guide rail. L-shaped hanging blocks are integrally connected to both sides of the T-shaped slide rail. The T-shaped slide rail and the L-shaped hanging blocks are slidably matched together with two sets of fixed placement components. The fixed placement components include J-shaped buckles that slide and match together with the T-shaped slide rail and the L-shaped hanging blocks. A lifting column mounting block is integrally connected to the J-shaped buckle. The lifting column mounting block is provided with two limiting slide grooves inside. The limiting slide grooves are slidably matched with the lifting column. A spring assembly is connected between the lifting column and the limiting slide grooves. A trolley mounting plate is placed on the two sets of fixed placement components.

[0006] Furthermore, the horizontal height of the heating element is lower than that of the intermediate track support and the edge track support. This design prevents contact with the heating element and thus avoids short circuits.

[0007] Furthermore, the fixed placement component is divided into a front fixed placement component and a rear fixed placement component. The rear fixed placement component is connected with a baffle. This design facilitates the quick placement of the trolley mounting plate.

[0008] Furthermore, the edge track support is provided with scale lines, a design that facilitates rapid positioning of the guide rail.

[0009] Furthermore, the horizontal height of the lifting column protrudes beyond the horizontal height of the T-shaped slide rail. This design facilitates its use with the trolley mounting plate.

[0010] Furthermore, the guide rail and the slider are integrally formed, which ensures a strong connection and prevents breakage.

[0011] Furthermore, several ball bearings are installed on the contact surface between the L-shaped hanging block and the J-shaped fastener, which increases the sliding effect of the J-shaped fastener.

[0012] Furthermore, the sliding plate and the sliding groove are fitted with a clearance, which provides good stability and prevents deviation.

[0013] Furthermore, the ends of the lifting column are rounded, a design that facilitates its integration with the trolley mounting plate.

[0014] Furthermore, both the intermediate track support and the edge track support are equipped with shims, a design that allows for adjustment of the installation height of the intermediate track support and the edge track support.

[0015] The beneficial effects of using the present invention are as follows:

[0016] The interaction between the slider and the groove in this invention limits the position of the intermediate track support by the guide rail, ensuring that the track and the intermediate track support are perpendicular to each other. When the intermediate track support is fixed, the guide rail is not prone to positional displacement under force, resulting in good stability.

[0017] The invention utilizes the interlocking of the mating plate, mating hole, and position adjustment hole to facilitate adjustment of the distance between the two guide rails, thereby adapting to trolley mounting plates of different widths and enhancing adaptability.

[0018] The connection method of the guide rail, intermediate track support and edge track support of the present invention makes it easy to disassemble and remove the furnace body for replacement and maintenance when the guide rail wears out after long-term use. Compared with the prior art, which repairs in the furnace body, it is more convenient and more practical.

[0019] The fixed placement component of this invention limits the position of the trolley mounting plate, making it less prone to positional displacement during movement and easy to remove. Attached Figure Description

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figures 1-4As shown, the trolley travel track of a low-temperature resistance furnace according to the present invention includes several intermediate track support members 1 and two edge track support members 2 fixed to the bottom of the furnace body 1'. The longitudinal cross-section of the intermediate track support members 1 and the edge track support members 2 is inverted T-shaped. Fixing holes 3 are provided on both sides of the intermediate track support members 1 and the edge track support members 2. A heating element 4 is installed between two adjacent intermediate track support members 1. The intermediate track support members 1 are provided with a sliding groove 5. The edge track support members 2 are provided with several position adjustment holes 6. The position adjustment holes 6 are matched with locking screws. Two guide rails 7 are placed on the intermediate track support members 1 and the edge track support members 2. The guide rails 7 are provided with sliding pieces 8 that match the sliding grooves 5. The two ends of the guide rails 7 are integrally connected with... The mating plate 9 has mating holes 10. A T-shaped slide rail 11 is integrally connected to the guide rail 7. L-shaped hanging blocks 12 are integrally connected to both sides of the T-shaped slide rail 11. The T-shaped slide rail 11 and the L-shaped hanging blocks 12 are slidably matched together with two sets of fixed placement components 13. The fixed placement component 13 includes a J-shaped buckle 131 that slides and matches together with the T-shaped slide rail 11 and the L-shaped hanging blocks 12. A lifting column mounting block 132 is integrally connected to the J-shaped buckle 131. The lifting column mounting block 132 has two limiting slide grooves 133 inside. A lifting column 134 is slidably matched with the limiting slide grooves 133. A spring assembly 135 is connected between the lifting column 134 and the limiting slide grooves 133. A trolley mounting plate is placed on the two sets of fixed placement components 13.

[0029] In this embodiment, when using a trolley track for a low-temperature resistance furnace, the intermediate track support 1 and the edge track support 2, suitable for the bottom space of the furnace body 1', are placed at the bottom of the furnace body 1'. The intermediate track support 1, the edge track support 2, and the heating element 4 are arranged in a wavy pattern. Then, the guide rail 7 is placed on the upper side of the intermediate track support 1 and the edge track support 2. The cooperation between the sliding plate 8 and the sliding groove 5 limits the position of the intermediate track support 1, ensuring that the track 7 and the intermediate track support 1 are perpendicular to each other. When the intermediate track support 1 and the edge track support 2 are fixed through the fixing hole 3, the guide rail 7 is not prone to positional displacement under force, and has good stability. The cooperation between the mating plate 9, the mating hole 10, and the position adjustment hole 6 facilitates the adjustment of the distance between the two guide rails 7 to accommodate trolley mounting plates of different widths, enhancing adaptability. After the guide rail 7, the intermediate track support 1, and the edge track support 2 are fixed, the two sets of fixed placement components 13 are slid into the guide rail 7 for installation. The installation of the mounting component 13 is straightforward. During use, the front end of the trolley mounting plate is placed between the two sets of fixed mounting components 13. The trolley mounting plate is then laid flat on the guide rail 7 and pushed forward along the guide rail. This allows the lifting column 134 to be easily inserted into the corresponding hole of the trolley mounting plate. With the spring assembly 135 in place, both sets of lifting columns 134 fix the trolley mounting plate in position, preventing any lateral shift. Furthermore, when the trolley mounting plate is pushed with a normal force, the two sets of fixed mounting components 13 also move accordingly, facilitating the pushing of the trolley mounting plate into the furnace body 1'. After the object on the trolley mounting plate has finished heating, the trolley mounting plate can be slid out of the guide rail 7. With a little more force, the trolley mounting plate can be removed quickly and easily. The connection method between the guide rail 7 and the intermediate track support 1 and the edge track support 2 allows for easy disassembly and removal from the furnace body 1' for replacement and maintenance after prolonged use if the guide rail 7 becomes worn. This is more convenient and practical than maintenance within the furnace body 1' in existing technologies.

[0030] Preferably, the horizontal height of the heating element 4 is lower than that of the intermediate track support 1 and the edge track support 2. This design prevents them from contacting the heating element 4 and thus avoids short circuits. In practice, the horizontal height of the heating element 4 can also be considered depending on the specific circumstances.

[0031] The preferred fixed placement component 13 is divided into a front fixed placement component 1301 and a rear fixed placement component 1302. The rear fixed placement component 1302 is connected to a baffle 1303. This design facilitates the quick placement of the trolley mounting plate. In fact, measures to facilitate the quick placement of the trolley mounting plate can also be considered according to specific circumstances.

[0032] The preferred edge track support 2 is equipped with scale lines. This design facilitates the rapid positioning of the guide rail 7. In fact, the scale line marking method can also be considered according to specific circumstances.

[0033] Preferably, the horizontal height of the lifting column 134 protrudes beyond the horizontal height of the T-shaped slide rail 11. This design facilitates its use with the trolley mounting plate. In practice, the horizontal height of the lifting column 134 can also be considered according to specific circumstances.

[0034] The guide rail 7 and the slider 8 are preferably integrally molded. This design ensures a strong connection and prevents breakage. In practice, the connection method between the guide rail 7 and the slider 8 can also be considered depending on the specific circumstances.

[0035] Preferably, several ball bearings are installed on the contact surface between the L-shaped hanging block 12 and the J-shaped fastener 131. This design increases the sliding effect of the J-shaped fastener 131. In fact, a structure that increases the sliding effect of the J-shaped fastener 131 can also be considered depending on the specific situation.

[0036] The preferred design is a clearance fit between the slider 8 and the groove 5. This design provides good stability and prevents misalignment. In practice, the clearance fit size can also be considered depending on the specific circumstances.

[0037] The end of the preferred lifting column 134 is rounded. This design facilitates its fit with the trolley mounting plate. In practice, the size of the rounded corner can also be considered depending on the specific situation.

[0038] It is preferable that both the middle track support 1 and the edge track support 2 are equipped with shims. This design allows for adjustment of the installation height of the middle track support 1 and the edge track support 2. In practice, the thickness and quantity of the shims can also be considered according to specific circumstances.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
