Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically a hoisting device for metal heat treatment. Background Technology

[0002] Metal heat treatment is a process of treating metals. By performing heat treatment operations on metals, the surface or internal microstructure characteristics of the metal can be effectively changed. Metal materials are often hoisted into a heating chamber for heat treatment using lifting equipment.

[0003] According to a published application for a metal heat treatment hoisting device (publication number: CN118255248B), the aforementioned application uses multiple clamping plates to simultaneously apply force to the metal outer wall from above and below to improve the stability of the metal clamping and fixing. Under the control of the drive component, the multiple clamping plates distributed in a ring change their deflection direction sequentially and at intervals. In order to ensure the metal is clamped and fixed stably during hoisting, the contact position between the outer surface of the metal and the clamping plates at various positions can be continuously changed, so that each position of the metal surface can come into contact with the air in the heat treatment chamber, thereby improving the work efficiency and work effect of metal surface heat treatment.

[0004] However, in actual use, when smaller metals need to be heat-treated, the above equipment requires placing the small metals on a rack and then using a hoisting device to lift the rack into the heat treatment device. When lifting the equipment, it takes a long time to separate and fix the hoisting ropes to the rack. In view of this, we propose a hoisting device for metal heat treatment. Utility Model Content

[0005] The purpose of this invention is to provide a hoisting device for metal heat treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for metal heat treatment, comprising a mounting component, a hoisting rope fixedly connected to the bottom of the mounting component, and a stabilizing component provided at the bottom of the mounting component, the stabilizing component comprising:

[0007] A large electric telescopic rod is fixedly connected to the bottom of the mounting component. The large electric telescopic rod is fixedly connected to a fixing component, and a small electric telescopic rod is fixedly connected to the inner wall side of the fixing component.

[0008] The movable component is fixedly connected to the end of the small electric telescopic rod, and a roller is rotatably connected to the inner wall side of the movable component. A mounting bracket is fixedly connected to the upper surface of the movable component.

[0009] The placement slot is located on the side of the mounting frame. A motor is fixedly connected to the front of the mounting frame. A threaded rod is fixedly connected to the output end of the motor. A threaded block is threadedly connected to the outer surface of the threaded rod. A limit roller is rotatably connected to the side of the threaded block.

[0010] Preferably, the size of the threaded block is adapted to the size of the placement groove, and the threaded block is disposed inside the placement groove, which allows the threaded block to move inside the placement groove.

[0011] Preferably, the movable component is disposed inside the fixed component, and the outer surface of the roller is in contact with the outer surface of the suspension rope, which allows the roller to push the suspension rope more effectively.

[0012] Preferably, the center of the limiting roller corresponds to the center of the roller, and the outer surface of the limiting roller is provided with an arc-shaped surface, which allows the limiting roller to more stably limit the suspension rope.

[0013] Preferably, the bottom of the fixing member is provided with an auxiliary component, the auxiliary component including a slide groove, the slide groove being formed at the bottom of the fixing member, a slider being slidably connected inside the slide groove, a connecting rod being hinged to the bottom of the slider, and a limit member being hinged to the end of the connecting rod.

[0014] Preferably, the limiting member is arranged in a ring shape, the center of the limiting member corresponds to the center of the fixing member, and the limiting member is disposed on the outer surface of the suspension rope.

[0015] Preferably, the center of the connecting rod corresponds to the center of the slider, and the size of the slider is adapted to the size of the groove.

[0016] Compared with the prior art, the present invention provides a hoisting device for metal heat treatment, which has the following advantages:

[0017] 1. In order to enable the lifting ropes to be separated quickly, when the equipment is lifting the rack inside the heat treatment device, the large electric telescopic rod moves the fixed part downward, while the small electric telescopic rod extends to move the movable part away from the large electric telescopic rod. This allows the rollers to push the lifting ropes to separate from each other. At the same time, the motor starts and the threaded rod drives the threaded block to move closer to the lifting ropes, so that the limit roller and the roller limit the lifting ropes. This allows the lifting ropes to be separated stably, and the lifting ropes can lift the rack inside the heat treatment device more quickly.

[0018] 2. In order to make the lifting rope more stable, the lifting rope can drive the limiting component to move when the lifting rope is pushed by the roller, so that the connecting rod can pull the slider to move inside the slide groove. This makes the lifting rope more stable after separation. Attached Figure Description

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a hoisting device for metal heat treatment, including a mounting component 1, a hoisting rope 2 fixedly connected to the bottom of the mounting component 1, and a stabilizing component 3 provided at the bottom of the mounting component 1. The stabilizing component 3 includes a large electric telescopic rod 301, a fixing component 302, a small electric telescopic rod 303, a movable component 304, a roller 305, a mounting frame 306, a placement groove 307, a motor 308, a threaded rod 309, a threaded block 310, and a limiting roller 311.

[0025] In this embodiment of the utility model, the large electric telescopic rod 301 is fixedly connected to the bottom of the mounting component 1. A fixing component 302 is fixedly connected to the large electric telescopic rod 301. A small electric telescopic rod 303 is fixedly connected to the inner wall of the fixing component 302. A movable component 304 is fixedly connected to the end of the small electric telescopic rod 303. The movable component 304 is disposed inside the fixing component 302. A roller 305 is rotatably connected to the inner wall of the movable component 304. The outer surface of the roller 305 contacts the outer surface of the suspension rope 2, allowing the roller 305 to better push the suspension rope 2. A mounting bracket 306 is fixedly connected to the upper surface of the movable component 304, and a placement groove 307 is formed in the mounting bracket 306. On the side, a motor 308 is fixedly connected to the front of the mounting bracket 306. A threaded rod 309 is fixedly connected to the output end of the motor 308. A threaded block 310 is threadedly connected to the outer surface of the threaded rod 309. The size of the threaded block 310 is adapted to the size of the placement groove 307. The threaded block 310 is set inside the placement groove 307, which allows the threaded block 310 to move inside the placement groove 307. A limiting roller 311 is rotatably connected to the side of the threaded block 310. The center of the limiting roller 311 corresponds to the center of the roller 305. The outer surface of the limiting roller 311 is provided with an arc-shaped surface, which allows the limiting roller 311 to more stably limit the suspension rope 2.

[0026] Meanwhile, an auxiliary component 4 is provided at the bottom of the fixing member 302. The auxiliary component 4 includes a slide groove 401, which is opened at the bottom of the fixing member 302. A slider 402 is slidably connected inside the slide groove 401. The size of the slider 402 is adapted to the size of the slide groove 401. A connecting rod 403 is hinged to the bottom of the slider 402. The center of the connecting rod 403 corresponds to the center of the slider 402. A limiting member 404 is hinged to the end of the connecting rod 403. The limiting member 404 is arranged in a ring shape. The center of the limiting member 404 corresponds to the center of the fixing member 302. The limiting member 404 is located on the outer surface of the lifting rope 2. This allows the lifting rope 2 to move the limiting member 404 when it is pushed by the roller 305. In turn, the connecting rod 403 pulls the slider 402 to move inside the slide groove 401. This makes the lifting rope 2 more stable after separation.

[0027] In this invention, during use, when the equipment is hoisting the placement rack inside the heat treatment device, the large electric telescopic rod 301 moves the fixed part 302 downward, while the small electric telescopic rod 303 extends, moving the movable part 304 away from the large electric telescopic rod 301. This allows the roller 305 to push the lifting rope 2 to separate from each other. At the same time, the motor 308 starts, causing the threaded rod 309 to drive the threaded block 310 closer to the lifting rope 2. This allows the limiting roller 311 to cooperate with the roller 305 to limit the lifting rope 2, thus enabling the lifting rope 2 to separate stably and allowing the lifting rope 2 to lift the placement rack inside the heat treatment device more quickly.

[0028] Furthermore, when the lifting rope 2 is pushed by the roller 305, the lifting rope 2 can drive the limiting member 404 to move, which in turn can cause the connecting rod 403 to pull the slider 402 to move inside the slide groove 401, so that the lifting rope 2 can be more stable after being separated.

[0029] 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.
