Description

Technical Field

[0001] This utility model mainly relates to the field of heat treatment furnace technology, specifically to a support device with an adjustable tilt angle for the furnace body of a heat treatment furnace. Background Technology

[0002] The adjustment angle of the heat treatment furnace body is mainly for inclined, rotary, or specific process requirements. The core purpose is to adapt to the heat treatment process requirements, optimize the material processing effect, improve production efficiency, and ensure stable equipment operation. For heat treatment furnaces that process granular, powdery, or liquid workpieces, such as rotary roasting furnaces and aluminum alloy melt heat treatment furnaces, angle adjustment is the key to controlling the movement of materials.

[0003] Existing furnace tilt adjustment devices mostly employ a screw + rotary motor drive structure. The rotary motor drives the screw to rotate, and the screw-nut thread transmission converts the rotational motion into linear motion, which is then used to adjust the furnace body angle via a connecting rod or bracket. However, in this type of structure, the screw needs to be designed with a long axial length to meet the adjustment requirements of a large tilt range of the furnace body, resulting in a large lateral space occupation of the device. This is especially problematic in scenarios with compact workshop equipment layouts, where installation space is easily limited. Furthermore, the rotary motor requires a matching reduction mechanism, further increasing the overall size of the equipment. The thread transmission is also prone to wear and tear, affecting adjustment accuracy and stability. In addition, the lubrication and maintenance costs of the screw and nut are high, and long-term use can easily lead to jamming failures.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," "provided with," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components.

[0020] See attached document Figure 1-2 A support device for a heat treatment furnace with an adjustable tilt angle includes a mounting base 1. The mounting base 1 is provided with two parallel linear slide rails 2. The linear slide rails 2 are provided with limit blocks 3. Sliding hinge seats 4 are provided on both sides of the limit blocks 3. Extending arms 5 are connected to the sliding hinge seats 4. The upper ends of the two extending arms 5 are connected to buffer lifting platforms 6. Hydraulic cylinders 7 are provided on the outer sides of the two linear slide rails 2. The buffer lifting platform 6 includes a lifting frame 601 and a shock absorption component 602.

[0021] Mounting base 1 is used to fix and connect linear slide rail 2 and hydraulic cylinder 7, providing a stable mounting reference for the device and ensuring that the components maintain structural integrity during operation.

[0022] Two linear slide rails 2 are parallel and fixedly installed on the mounting base 1, providing precise linear guidance for the sliding hinge base 4, ensuring that the sliding hinge base 4 moves smoothly in a straight line, and achieving the guiding function of precise adjustment of the tilt angle.

[0023] The limiting block 3 is located in the middle of the mounting base 1 and is fixedly connected to the linear slide rail 2. It limits the sliding stroke of the sliding hinge seat 4 to prevent it from slipping off the linear slide rail 2 due to excessive sliding, thus playing a protective role in limiting the stroke.

[0024] The sliding hinge seat 4 is slidably mounted on the linear slide rail 2 and is located on both sides of the limiting block 3. One end of the hinge seat 4 is hinged to the extension arm 5 via a pin, and the other end is connected to the guide rod 8, which is used to convert the horizontal driving force of the hydraulic cylinder 7 into the swinging power of the extension arm 5.

[0025] The two ends of the boom 5 are respectively hinged to the sliding hinge seat 4 and the connecting ear plate 603 of the buffer lifting platform 6 via pins, forming a linkage transmission mechanism. When the sliding hinge seat 4 slides along the linear slide rail 2, the boom 5 swings, converting the horizontal movement into the lifting and tilting movement of the buffer lifting platform 6. The compact linkage layout greatly saves the horizontal installation space of the equipment.

[0026] The buffer lifting platform 6 consists of a lifting frame 601 and a shock-absorbing component 602. The lifting frame 601 has connecting ear plates 603 on both sides, which are hinged to the extension arm 5 through pins to realize force transmission and angle adjustment. The shock-absorbing component 602 is embedded inside the lifting frame 601 and consists of a positioning sleeve and multiple damping spring shafts. The positioning sleeve provides installation positioning for the damping spring shafts. The upper end of the damping spring shaft protrudes from the upper end face of the lifting frame 601. When the heat treatment furnace body is placed, it can buffer the weight impact of the furnace body and the vibration during the adjustment process, thereby improving the stability of the device and the safety of the furnace body. One end of the extension arm 5 is hinged to the lifting frame 601 through the connecting ear plate 603 to ensure that the extension arm 5 can effectively drive the lifting frame to achieve angle adjustment when it swings.

[0027] Two hydraulic cylinders 7 are fixed in mirror image on the mounting base 1 and distributed on the outside of the linear slide rail 2. Their telescopic rods are fixedly connected to the push plate 9. Compared with the traditional structure of motor-driven screw, the linear drive of the hydraulic cylinders 7 does not require a lot of rotation and transmission space, which greatly saves the equipment installation space. At the same time, it has the advantages of stable power output and fast adjustment response, providing reliable power for tilt angle adjustment.

[0028] One end of the guide rod 8 is connected to the sliding hinge seat 4, and the other end is connected to the L-shaped push plate 9. The push plate 9 is fixedly connected to the telescopic rod of the hydraulic cylinder 7. The guide rod 8 plays an auxiliary guiding role to ensure that the sliding hinge seat 4 slides smoothly along the linear slide rail 2 and enhances the transmission stability. The L-shaped push plate 9 improves the reliability of force transmission by increasing the contact area.

[0029] The push plate 9 is an L-shaped plate, which serves as the force transmission medium between the hydraulic cylinder 7, the guide rod 8, and the sliding hinge seat 4, ensuring that the driving force of the hydraulic cylinder 7 can be effectively transmitted to the sliding hinge seat.

[0030] In summary, this technical solution replaces the traditional motor-driven screw structure with a compact layout of hydraulic cylinder-driven connecting rod, significantly saving equipment installation space. At the same time, combined with the precise guidance of linear slide rails and the buffer protection of shock-absorbing components, it achieves efficient and stable adjustment of the furnace body tilt angle.

[0031] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
