Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically to a furnace door tensile testing mechanism. Background Technology

[0002] In industrial production, various kilns are needed, such as heating furnaces, drying furnaces, and smelting furnaces. Since these kilns and their doors are very large, it is necessary to test whether the opening and closing of the doors is smooth before they leave the factory. Therefore, it is necessary to conduct a tensile test on the doors to ensure the quality of the door installation. In the existing technology, manual testing is generally carried out using a tensile gauge. Since the opening and closing path of the doors is arc-shaped, manual testing is not only inefficient but also yields inaccurate results. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a furnace door tension detection mechanism, which realizes automatic detection of furnace door tension. It has a simple structure, good accuracy, and high efficiency.

[0004] Specifically, this utility model discloses a furnace door tensile testing mechanism, comprising:

[0005] A pull arm is equipped with a handle and a force sensor, the handle being used to pull the furnace door;

[0006] The push-back assembly, including a push rod, is used to close the furnace door;

[0007] The moving device is used to move the pulling arm and the push-back assembly to realize the automatic opening and closing of the furnace door.

[0008] The advantages of adopting the above technical solution are that the automatic movement of the handle realizes the automatic detection of the furnace door tension, the structure is simple, and the door is automatically pushed back after being opened, which is efficient, accurate, and can be repeatedly tested.

[0009] Furthermore, the pull arm is provided with a rotating shaft, which is mounted via a mounting plate. Springs are connected to both sides of the pull arm, and the other end of each spring is connected to the mounting plate.

[0010] The advantage of adopting the above technical solution is that the setting of the rotating shaft gives the pulling arm a certain rotational capacity, and the springs installed on both sides limit the rotation angle, so that the entire pulling arm can rotate within a certain range, avoiding the furnace door from getting stuck during the process of pulling the furnace door, while ensuring smooth opening and closing.

[0011] Furthermore, the handle has an arc-shaped hook for pulling the furnace door handle, and the force sensor is used to connect the handle and the pulling arm.

[0012] The advantage of adopting the above technical solution is that by setting a tension sensor to detect the tension of the furnace door during the opening and closing process, and setting a handle to hook the handle of the furnace door, the door is released after detection. The whole process is driven by a moving device and does not require manual intervention.

[0013] Furthermore, the push-back assembly also includes a connecting plate, a moving plate, and a driving component. The connecting plate is connected to the moving device and has a guide rail mounted on it. The moving plate moves along the guide rail. The push rod is connected to the moving plate. The driving component drives the moving plate to move, causing the push rod to extend and retract.

[0014] The advantage of adopting the above technical solution is that the moving plate drives the push rod to extend and push the furnace door to close, thereby realizing the automatic closing of the furnace door. Moreover, the moving plate is limited by the guide rail to ensure the pushing position.

[0015] Furthermore, rollers are provided on both sides of the push rod.

[0016] The advantage of adopting the above technical solution is that the roller is designed to connect with the push rod, and the roller makes rolling contact with the furnace door during the closing process, ensuring that the furnace door closes smoothly.

[0017] Furthermore, the driving component is connected to a buffer assembly, including a connecting block, a side push block, and a guide shaft. The connecting block is connected to the output end of the driving component, and the side push block is connected to the connecting block through the guide shaft. An elastic element is sleeved on the guide shaft, and one end of the guide shaft can slide within the side push block.

[0018] The advantage of adopting the above technical solution is that, during the process of closing the furnace door, the elastic element provides elastic force to the side push block, allowing the side push block to slide a certain distance along the guide shaft, thus avoiding collision damage to the furnace door.

[0019] Furthermore, the moving device includes a horizontal moving module and a vertical moving module. The horizontal moving module drives the vertical moving module to move horizontally, and the vertical moving module drives the pulling arm and the pushing back assembly to move.

[0020] The advantage of adopting the above technical solution is that the moving module makes the handle form an arc-shaped moving trajectory, realizing the opening and closing of the furnace door.

[0021] Furthermore, the roller surface has an elastic protective layer.

[0022] The advantage of adopting the above technical solution is that the elastic protective layer avoids scratches on the furnace door, thus playing a protective role and ensuring the aesthetic appearance of the furnace door.

[0023] Furthermore, the pull arm has multiple through holes.

[0024] The advantage of adopting the above technical solution is that the setting of multiple through holes can effectively reduce the weight of the entire pulling arm, making the movement of the entire pulling arm smoother. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] like Figure 1-2 As shown, this utility model discloses a furnace door tensile testing mechanism, comprising:

[0034] A pull arm 1 is equipped with a handle 11 and a tension sensor 12. The handle 11 is used to pull the furnace door.

[0035] The push-back assembly, including push rod 2, is used to close the furnace door;

[0036] A moving device is used to move the pulling arm 1 and the push-back assembly to realize the automatic opening and closing of the furnace door.

[0037] The advantages of adopting the above technical solution are that the automatic movement of the handle 11 realizes the automatic detection of the furnace door tension, the structure is simple, and the door is automatically pushed back after being opened, which is efficient, accurate, and can be repeatedly tested.

[0038] The pull arm 1 is equipped with a rotating shaft 13, which is fixedly mounted via a mounting plate 14. The mounting plate is fixedly connected to a moving device and moves with the moving device. The pull arm 1 can rotate around the rotating shaft 13. Springs 16 are connected to both sides of the pull arm 1, and the two springs 16 are arranged on the same straight line. The mounting plate 14 is equipped with symmetrically arranged fixing blocks 17, on which fixing nails are installed. The other end of the spring 16 is fixed to the fixing nails. At the same time, the fixing nails can be fixed to the mounting plate 14 at multiple points to realize the adjustment of the spring force. The fixed position of the springs 16 on the pull arm 1 is offset from the installation position of the rotating shaft 13, so that when the end of the pull arm 1 swings, it is restricted by the tension of the two springs 16, limiting the rotation angle of the pull arm 1 and ensuring smooth opening and closing of the furnace door. At the same time, the pull arm 1 has multiple through holes 15, reducing the weight of the entire pull arm 1, facilitating control, and making it flexible in movement.

[0039] Furthermore, the handle 11 has an arc-shaped hook 111 for pulling the handle 6 of the furnace door. The outer side of the handle 11 is flat to prevent collision with other parts during the pulling process. The tension sensor 12 is used to connect the handle 11 and the pulling arm 1. The tension sensor 12 detects the tension of the furnace door during the opening process and records and transmits the data to the control system. At the same time, a display can be set to display the tension value. During the detection, the handle 11 hooks onto the handle 6 on the furnace door. After the detection is completed, the handle 11 is disengaged from the handle 6 by the movement device.

[0040] In some implementations, the push-back assembly further includes a connecting plate 21, a movable plate 22, and a drive unit 24. The connecting plate 21 is connected to the moving device and is fixedly mounted on the mounting plate 14. A guide rail 23 is mounted on the connecting plate 21, and a slider is provided on the guide rail 23. The slider is fixedly mounted to the movable plate 22. The guide rail 23 is horizontally mounted, and the movable plate 22 moves along the guide rail 23. The push rod 2 is fixedly mounted to the movable plate 22. The drive unit 24 drives the movable plate 22 to move, causing the push rod 2 to extend and retract. The drive unit 24 is an adjustable stroke cylinder. After the tension test is completed, the drive unit 24 extends, driving the movable plate to move horizontally. At this time, the push rod 2 contacts the furnace door, and the furnace door is closed under the action of the moving device.

[0041] Furthermore, rollers 25 are provided on both sides of the push rod 2. The rollers 25 are rotatable and installed with the push rod 2. The surface of the rollers 25 has an elastic protective layer. The rollers 25 are located on both sides of the handle 11 and make rolling contact with the furnace door. The elastic protective layer can be a rubber layer, which is elastic. During the process of closing the furnace door, the rollers 25 make rolling contact with the furnace door to ensure that the furnace door closes smoothly.

[0042] Furthermore, the drive component 24 is connected to a buffer assembly, including a connecting block 3, a side push block 31, and a guide shaft 32. The connecting block 3 is connected to the output end of the drive component 24. The side push block 31 is connected to the connecting block 3 via the guide shaft 32. There are two guide shafts 32, which are symmetrically arranged. An elastic element 33, which can be a spring 16, is sleeved on the guide shaft 32. A through hole is provided on the side push block 31. One end of the guide shaft 32 passes through the through hole and slides inside. At the same time, a stop is provided at the end of the guide shaft 32 to prevent the guide shaft 32 from coming out of the through hole. The upper side of the side push block 31 is fixedly installed with the moving plate 22. The drive component 24 drives the side push block 31 to move, thereby driving the moving plate 22 to move, realizing the extension and retraction of the push rod 2.

[0043] In some implementations, the moving device includes a horizontal moving module 4 and a vertical moving module 5. The horizontal moving module 4 drives the vertical moving module 5 to move horizontally, and the vertical moving module 5 drives the pulling arm 1 and the push-back assembly to move. The horizontal moving module 4 and the vertical moving module 5 can be lead screw motor modules, which have high operating accuracy. The two work together to make the handle 11 form the arc trajectory required for opening the door. In addition, the entire device has a support frame, and the entire mechanism is installed according to the position of the furnace door and the usage. Casters can be installed on the underside of the support frame to facilitate the movement of the entire device. Multiple sensors, such as photoelectric sensors and ultrasonic sensors, are installed on the horizontal moving module 4 and the vertical moving module 5 to sense the movement position of the handle.

[0044] Usage process, such as Figure 3-4 As shown, where, Figure 4 The movable device and spring 16 are concealed. First, driven by the horizontal moving module 4 and the vertical moving module 5, the handle 11 hooks the handle 6, and then the handle 11 moves to open the furnace door. During the opening process, the entire handle 11 moves in an arc with the furnace door. Throughout the process, the tension sensor 12 detects the tension of the furnace door. After the furnace door is opened to the set opening degree, the detection is completed. At this time, the push rod 2 on the push-back component extends, so that the roller 25 on the push rod 2 contacts the furnace door. Then the entire movable device moves in the opposite direction, and the roller 25 pushes the furnace door to close. At the same time, during the closing process, the handle 11 also hooks the handle 6 to prevent the furnace door from closing suddenly. After the furnace door is closed, the push rod 2 retracts, the handle 11 exits, and the detection is completed. The structure is simple, realizes automatic detection of furnace door tension, and the detection results are accurate and efficient.

[0045] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
