Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, specifically to a straight-in ladle slide mechanism that reduces steel leakage from the slide. Background Technology

[0002] A ladle is used in steel plants and foundries to receive molten steel and perform pouring operations in front of open-hearth furnaces, electric furnaces, or converters. A sliding gate is a control device for molten steel during the continuous casting process. It can precisely adjust the water flow from the ladle to the tundish, so that the inflow and outflow of molten steel reach a balance, making the continuous casting operation easier to control. It is an indispensable part of smelting.

[0003] In my country, large steel ladle slides weighing over 100 tons are mainly made of sintered aluminum-zirconium-carbon material, with a service life of 2 to 4 uses. For medium and small steel ladles, considering cost, the slides are mainly made of aluminum-carbon material, and the process is divided into three types: sintered, lightly sintered, and unsintered, with a service life of 1 to 3 uses.

[0004] In the actual replacement process, the aforementioned ladle slide plate is installed by the operator holding it high with both hands. This high-lift installation requires the operator to support the heavy object with force, which may lead to muscle fatigue, sprains, or other injuries, increasing labor intensity and easily causing occupational injuries. It also requires more manpower and time, resulting in low efficiency. Especially for the installation of large equipment, it may prolong the replacement time and affect the production schedule. In view of this, we propose a straight-in ladle slide plate mechanism to reduce steel leakage from the slide plate. Utility Model Content

[0005] The purpose of this invention is to provide a straight-through steel ladle slide mechanism that reduces steel leakage from the slide, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straight-in ladle slide mechanism for reducing steel leakage, comprising a forklift body, a lifting mechanism fixedly connected to the front end of the forklift body, a front fork fixedly connected to the output end of the lifting mechanism, and a lifting assembly provided at the bottom of the front fork, the lifting assembly comprising:

[0007] A slide rail is fixedly connected to the bottom end face of the front fork, the slide rail is slidably connected to a sliding block, and the sliding block is rotatably connected to a rotating arm.

[0008] A rotating arm is rotatably connected to the bottom of a rotating arm. A hinge rod is hinged to the end of the rotating arm away from the rotating arm, and an installation groove is provided on the end face of the hinge rod.

[0009] A clamping rod is hinged to the inner wall of the mounting groove, and the end face of the clamping rod is hinged to a mounting block. A motor is fixedly connected to the end face of the mounting block, and a screw is fixedly connected to the output end of the motor.

[0010] The clamping rod 2 is hinged to the inner wall of the mounting groove, the end face of the clamping rod 2 is hinged to the mounting block 2, the mounting block 2 is threadedly connected to the screw, and the clamping rod 2 is movably connected to the slide body.

[0011] Preferably, the end of the clamping rod one away from the mounting block one is fixedly connected with a bent portion, and the end of the clamping rod two away from the mounting block two is fixedly connected with a bent portion.

[0012] Preferably, the first clamping rod and the second clamping rod are arranged in an X-shape, and the outer wall of the first clamping rod is movably connected to the inner wall of the second clamping rod.

[0013] Preferably, a baffle is fixedly connected to the outer wall of the rotating arm, and the baffle is movably connected to the hinge rod.

[0014] Preferably, the lifting components are provided in two sets, and the two sets of lifting components are symmetrically arranged on the bottom end face of the two sets of front forks, which can be used to fix the slide body and the water inlet respectively.

[0015] Preferably, the side wall of the sliding block is rotatably connected to a roller, which is movably connected to the inner bottom surface of the slide rail. The roller reduces the friction of the sliding block's movement, making it easier to adjust the position of the slide body.

[0016] Compared with the prior art, this utility model provides a straight-through ladle slide mechanism that reduces steel leakage from the slide, and has the following beneficial effects:

[0017] 1. This straight-line steel ladle slide mechanism, which reduces steel leakage from the slide, uses a lifting component to clamp the slide body by moving the end of clamping rod one away from mounting block one and the side of clamping rod two away from mounting block two in opposite directions. This clamps the slide body, allowing the rotating arm to rotate and complete the installation of the slide body, improving operational efficiency and saving time and labor costs. Two sets of rotating arms are provided below one rotating arm. One set of rotating arms is used to fix the new slide body, while the clamping rod one and clamping rod two below the other set of rotating arms are used to clamp the old slide body. By rotating the rotating arm, the replacement time of the slide body is reduced, thereby reducing steel leakage. By providing bending parts on the end faces of clamping rod one and clamping rod two, the clamping force on the slide body is increased, ensuring that the slide body is not easy to slide or shift during operation.

[0018] 2. The straight-in ladle slide mechanism that reduces steel leakage in the slide plate restricts the rotation direction of the hinge rod by setting a baffle, so that the direction of the bending part of clamping rod one and clamping rod two is bent downward, thus ensuring that the hinge rod rotates around the fixed axis in a fixed direction during operation, limiting unnecessary rotation range and helping to accurately control the clamping action.

Detailed Implementation

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a straight-in ladle slide mechanism for reducing steel leakage on the slide, including a forklift body 1, a lifting machine 2 fixedly connected to the front end of the forklift body 1, a front fork 3 fixedly connected to the output end of the lifting machine 2, and a lifting assembly 4 provided at the bottom of the front fork 3. The lifting assembly 4 includes a slide rail 401, a sliding block 402, a roller 403, a rotating arm 404, a rotating arm 405, a hinge rod 406, a mounting groove 407, a clamping rod 1 408, a mounting block 1 409, a motor 410, a screw 411, a clamping rod 2 412, a mounting block 2 413, and a bending part 414.

[0025] In one embodiment of this utility model, the slide rail 401 is fixedly connected to the bottom end face of the front fork 3, the slide rail 401 is slidably connected to the sliding block 402, the sliding block 402 is rotatably connected to the rotating arm 404, the side wall of the sliding block 402 is rotatably connected to the roller 403, the roller 403 is movably connected to the inner bottom surface of the slide rail 401, the roller 403 reduces the friction of the sliding block 402 movement, making it easier to adjust the position of the skateboard body 6, the rotating arm 405 is rotatably connected to the bottom of the rotating arm 404, the end of the rotating arm 405 away from the rotating arm 404 is hinged to the hinge rod 406, and the end face of the hinge rod 406 is provided with a mounting groove 407.

[0026] The clamping rod 408 is hinged to the inner wall of the mounting groove 407. The end face of the clamping rod 408 is hinged to the mounting block 409. The end face of the mounting block 409 is fixedly connected to a motor 410. The output end of the motor 410 is fixedly connected to a screw 411. The end of the clamping rod 408 away from the mounting block 409 is fixedly connected to a bent part 414.

[0027] Clamping rod 408 is hinged to the inner wall of mounting groove 407, clamping rod 412 is hinged to mounting block 413, mounting block 413 is threaded to screw 411, clamping rod 412 is movably connected to slide body 6, and a bent part 414 is fixedly connected to the end of clamping rod 412 away from mounting block 413. Clamping rod 408 and clamping rod 412 are arranged in an X shape, and the outer wall of clamping rod 408 is movably connected to the inner wall of clamping rod 412.

[0028] There are two sets of lifting components 4, which are symmetrically arranged on the bottom end faces of the two sets of front forks 3. They can be used to fix the slide body 6 and the water inlet, respectively.

[0029] The lifting machine 2 drives the front fork 3 to move downwards, causing the articulated rod 406 to descend above the slide body 6. The lifting machine 2 continues to drive the front fork 3 to descend, allowing the articulated rod 406 to rotate around the rotating arm 405. This causes the bent part 414 to face the circular groove on the slide body 6, allowing the clamping rod 408 and clamping rod 412 to pass through the circular groove. Then, the motor 410 drives the screw 411 to rotate, causing the mounting block 409 and mounting block 413 to move in opposite directions. The end of clamping rod 408 away from mounting block 409 and the side of clamping rod 412 away from mounting block 413 move in opposite directions, thus clamping the slide body 6 and causing the rotating arm 405 to... 4. Rotation can complete the installation of the skateboard body 6, improving operating efficiency and saving time and labor costs. Two sets of rotating arms 405 are provided below one rotating arm 404. The lower part of one set of rotating arms 405 is used to fix the new skateboard body 6, and the clamping rod 1 408 and clamping rod 2 412 below the other set of rotating arms 405 are used to clamp the old skateboard body 6. By rotating the rotating arm 404, the replacement time of the skateboard body 6 is reduced, thereby reducing the exposure of the skateboard body. By providing a bending part 414 on the end face of clamping rod 1 408 and clamping rod 2 412, the clamping force on the skateboard body 6 is increased, ensuring that the skateboard body 6 is not easy to slide or shift during operation.

[0030] In addition, a baffle 5 is fixedly connected to the outer wall of the rotating arm 405. The baffle 5 is movably connected to the hinge rod 406. The baffle 5 restricts the rotation direction of the hinge rod 406, so that the direction in which the clamping rod 408 and the clamping rod 412 are provided with the bent part 414 is bent downward, thereby ensuring that the hinge rod 406 rotates around the fixed axis during operation, limiting unnecessary rotation range and helping to accurately control the clamping action.

[0031] In this invention, during use, the lifting machine 2 drives the front fork 3 to move downwards, causing the hinge rod 406 to descend above the slide plate body 6. The lifting machine 2 continues to drive the front fork 3 to descend, allowing the hinge rod 406 to rotate around the rotating arm 405. This causes the bent part 414 to align with the circular groove on the slide plate body 6, allowing the clamping rod 408 and clamping rod 412 to pass through the circular groove. Then, the motor 410 drives the screw 411 to rotate, with the end of clamping rod 408 away from mounting block 409 and the side of clamping rod 412 away from mounting block 413. Moving in the opposite direction clamps the skateboard body 6, allowing the rotating arm 404 to rotate and complete the installation of the skateboard body 6, improving operational efficiency and saving time and labor costs. Two sets of rotating arms 405 are provided below one rotating arm 404. The lower part of one set of rotating arms 405 is used to fix the new skateboard body 6, while the clamping rod 1 408 and clamping rod 2 412 below the other set of rotating arms 405 are used to clamp the old skateboard body 6. By rotating the rotating arm 404, the replacement time of the skateboard body 6 is reduced, thereby reducing the leakage of steel from the skateboard.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
