Description

Technical Field

[0001] This utility model belongs to the technical field of equipment repair tools, and specifically relates to a high-temperature online welding device for a slider inside a heating furnace. Background Technology

[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to the rolling or forging temperature. A heating furnace slider is a device used to support and fix steel billets inside the heating furnace. The slider is usually placed on the longitudinal water beam inside the heating furnace to support the movement of the steel billet and the heating of the furnace. The main function of the slider is to prevent the steel billet from bending, twisting or other deformations during the heating process, to ensure uniform heating of the steel billet and improve product quality.

[0003] Currently, Chinese utility model patent CN205129208U discloses a welding clamp rod capable of repairing the slider of a walking beam in a heating furnace at high temperatures. However, this device requires the removal of the cantilevered roller conveyor corresponding to the point where the slider has detached from the heating furnace before the welding clamp can be used to weld the slider. This process is cumbersome and makes it difficult to observe the position of the welding torch, affecting the welding efficiency and effectiveness of the slider, increasing production downtime, and reducing production efficiency and product quality. Therefore, there is a need to research and develop a device for online welding repair of sliders in the high-temperature environment of a heating furnace, which is easy to operate and ensures safe use. Utility Model Content

[0004] The purpose of this utility model is to provide a high-temperature online welding device for sliders inside a heating furnace. Its advantages are that the device can perform online welding repair on sliders in the high-temperature environment of the heating furnace, reducing production interruption time, improving production efficiency and product quality, and has a compact structure, simple operation, good welding effect, and high safety.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-temperature online welding device for a slider inside a heating furnace, comprising a lifting rod, a connecting rod welded to the bottom of the lifting rod, a pulley fixedly connected to the bottom of the connecting rod, a sliding rail slidably connected to the surface of the pulley, an equipment rod bolted to the bottom of the sliding rail, a welding mechanism inserted into the rear of the bottom of the equipment rod, the welding mechanism comprising a welding torch, the top of the welding torch inserted into the bottom of the equipment rod, a driven chain plate sleeved on the top of the welding torch, a chain meshing on the surface of the driven chain plate, a driving chain plate meshing at the other end of the chain, a motor sleeved on the inner wall of the driving chain plate, and the motor fixedly installed on the inner wall of the equipment rod.

[0006] The above technical solution involves observing the position of the slider on the display screen during welding operations. Moving the equipment rod forward or backward brings the welding torch closer to the slider. Control buttons control the motor's rotation, which in turn drives the drive chain to rotate, which in turn drives the driven chain to rotate. The driven chain then drives the welding torch, positioning the welding head at the desired welding position. The welding torch parameters are adjusted via control buttons to begin welding. This setup allows for efficient control of the welding torch from outside the furnace, enabling efficient slider repair. Furthermore, the angle of the welding torch can be adjusted to accommodate welding needs at different locations.

[0007] The present invention is further configured such that a clamping mechanism is inserted into the rear of the bottom of the device rod. The clamping mechanism includes a sleeve, a limiting block welded to the bottom of the sleeve, a connecting block welded to the bottom of the limiting block, a hydraulic rod sleeved on the inner wall of the limiting block, a displacement block welded to the bottom of the hydraulic rod, a transmission arm rotatably connected to the front and rear of the displacement block, a clamping arm rotatably connected to the other end of the transmission arm, a clamping arm rotatably connected to the middle of the surface of the clamping arm and the two sides of the connecting block, and a slider movably connected to the other end of the clamping arm.

[0008] The above technical solution allows for the following: When using the welding device, the position of the slider can be observed on the display screen. The device rod can be moved forward or backward, raised or lowered, so that the clamping arms are positioned on both sides of the slider. The hydraulic rod is extended or retracted via control buttons. The hydraulic rod drives the displacement block downward, which in turn drives the transmission arm to rotate and move downward. The other end of the transmission wall expands outward, causing the clamping arm to expand outward. Since the connecting block remains stationary, the other end of the clamping arm retracts inward, thus clamping the slider. This design allows for control of the clamping arm inside the furnace from outside the heating furnace, ensuring the slider is in a correct and stable position, facilitating welding operations. It also allows for slider replacement, reducing troubleshooting time, improving production efficiency, and lowering production costs.

[0009] The present invention is further configured such that a camera is inserted into the rear of the bottom of the device rod.

[0010] The above technical solution allows for the real-time transmission of images from inside the heating furnace to the control equipment's display screen by installing a camera. This enables the position of the welding torch and clamping arm to be observed from outside the furnace at any time, facilitating more accurate welding of the slider.

[0011] The present invention is further configured such that a partition is inserted inside the device rod, and the partition and the inner wall of the device rod form a wire harness cavity.

[0012] The above technical solution involves inserting a partition to create a dedicated wire harness cavity, which houses the wire harnesses for the camera, clamping mechanism, and welding mechanism, while also providing heat insulation.

[0013] The present invention is further configured such that a vertical rod is welded to the surface of the boom, an adjusting nut is threaded to both sides of the vertical rod, an adjusting vertical rod is sleeved on the surface of the vertical rod, and adjusting grooves are provided on both sides of the adjusting vertical rod.

[0014] The above technical solution allows for the adjustment of the height of the equipment rod by using the adjusting nut and the adjusting slide, which facilitates the clamping arm in clamping the slider and the welding gun in welding the slider.

[0015] The present invention is further configured such that a base is welded to the bottom of the adjusting rod, a control device is fixedly installed on the top of the base, a display screen is provided in front of the control device, and a control button is provided in front of the control device.

[0016] The above technical solution allows operators to conveniently adjust the parameters and positions of the welding torch and clamping arm in real time outside the heating furnace by uniformly setting up the display screen and control buttons on the control equipment, thereby reducing troubleshooting time.

[0017] The present invention is further configured such that a wire harness tube is inserted into the front of the device rod, and the other end of the wire harness tube is inserted into the back of the control device.

[0018] The above technical solution uses the combination of wire harness tubes and equipment rods to transmit the image of the heating furnace to the control equipment in real time, which facilitates operators to find and repair faults and avoids production time being affected by furnace shutdown and cooling.

[0019] The present invention is further provided that the bottom of the base is equipped with casters.

[0020] The above technical solution allows the welding device to be moved quickly and easily via the casters, enabling it to reach the heating furnace where the fault needs to be addressed for timely operation.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. When using this welding device, observe the position of the slider on the display screen, move the device rod forward or backward to bring the welding torch closer to the slider, control the motor to rotate via the control button, the motor drives the drive chain to rotate, the drive chain drives the driven chain to rotate, and the driven chain drives the welding torch to rotate, so that the welding head of the welding torch is positioned at the welding position. Adjust the parameters of the welding torch via the control button to start the welding work. This setting enables the welding torch inside the furnace to be controlled from outside the heating furnace, enabling efficient repair of the slider. At the same time, the angle of the welding torch can be adjusted to adapt to the welding needs of different positions.

[0023] 2. When using the welding device, observe the position of the slider on the display screen, move the device rod forward or backward, and raise or lower it to position the clamping arms on both sides of the slider. Control the extension and retraction of the hydraulic rod via the control buttons. The hydraulic rod drives the displacement block to move downward, which in turn drives the transmission arm to rotate and move downward. The other end of the transmission wall will expand outward, causing the clamping arm to expand outward. Since the connecting block is fixed, the other end of the clamping arm will retract inward, thus clamping the slider. This setting allows for control of the clamping arm inside the furnace from outside the heating furnace, ensuring the slider is in the correct and stable position, facilitating welding operations. It also allows for slider replacement, reducing troubleshooting time, improving production efficiency, and lowering production costs. Attached Figure Description
