Description

Technical Field

[0001] This utility model relates to the field of error prevention devices, specifically a high-safety bell jar upper-level error prevention device. Background Technology

[0002] Mistake-proofing devices, also known as error-proofing devices or foolproofing devices, are designed to prevent human error and ensure that products or equipment do not have defects or losses during the production process. Therefore, in industrial production, most heavy machinery and equipment are usually equipped with mistake-proofing devices to improve production efficiency and product quality.

[0003] When opening the bell-shaped furnace hood, a lifting structure is typically used to hoist the bell-shaped hood from the bottom of the furnace to above it. However, due to the excessive weight of the hood and its swaying under external forces during hoisting, it is difficult to maintain stability and there is a risk of it falling. Furthermore, the hood may shift or misalign during hoisting, requiring manual control to reassemble it with the furnace bottom. This reassembly process is cumbersome, time-consuming, and may even result in failure to reassemble, affecting the normal use of the hood. Utility Model Content

[0004] The purpose of this invention is to provide a highly secure upper-level anti-mistake device for bell jars, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-safety bell jar anti-foolproof device, comprising a U-shaped frame, the U-shaped frame being mounted on the top of the furnace hood, a vertical cylinder penetrating through the middle of the top of the U-shaped frame, a furnace bottom being provided at the bottom of the furnace hood, a distance sensor being provided on one side of the bottom of the furnace bottom, a controller being electrically connected to the bottom of the distance sensor, electric cylinders being installed on both side walls of the U-shaped frame, a horizontal bar being engaged at the output end of the electric cylinder, two vertical rods being provided on the inner side of the U-shaped frame, a collar being fixedly connected to the bottom end of the vertical rods, a base being fixedly connected to the bottom end of the U-shaped frame, and side frames being fixedly connected to both side walls of the base.

[0006] Preferably, the top of the furnace hood is connected to the wire rope of the lifting structure, and the wire rope is movably interlocked with the vertical cylinder.

[0007] Preferably, the top end of the vertical rod is fixedly connected to the U-shaped frame, and the collar is fixedly connected to the U-shaped frame through the vertical rod.

[0008] Preferably, the crossbar is movably connected to the collar via an electric cylinder, and a rubber block is fixedly connected to the end of the crossbar away from the electric cylinder.

[0009] Preferably, a rolling ball is movably embedded in the middle of the rubber block, and the rolling ball is slidably connected to the furnace hood via a crossbar.

[0010] Preferably, both sides of the inner wall of the U-shaped frame are fixedly connected with internal diagonal braces.

[0011] Preferably, the controller is installed inside the edge of the furnace bottom and is electrically connected to the two electric cylinders.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This highly secure bell-shaped furnace hood anti-foolproof device, through a vertical rod, lifting ring, electric cylinder, and horizontal bar, allows the electrically driven cylinder to push the horizontal bar to move towards both sides of the furnace hood during the lifting process. This enables the ball bearing at the end of the horizontal bar to adhere to the outer wall of the furnace hood, limiting the upward path of the furnace hood and maintaining better stability during the ascent. This reduces the probability of the furnace hood swaying during lifting and minimizes the risk of it falling to the ground.

[0013] 2. This highly secure bell-shaped furnace cover upper-level anti-misalignment device, through distance sensors, controllers, and limit cylinders, enables the bottom of the furnace cover and the top of the furnace bottom to measure distances via sensors during the lowering process of the furnace cover by the lifting structure. The signal is transmitted to the controller, which then activates the electric cylinder to limit the furnace cover. This prevents misalignment or displacement of the furnace cover during the re-alignment process with the furnace bottom, thereby saving the time required for the furnace cover to align with the furnace bottom and reducing the probability of the furnace cover and furnace bottom failing to align properly.

[0019] like Figures 1 to 4 As shown, the high-safety bell jar anti-mistake device of this embodiment includes a U-shaped frame 1, which is mounted on the top of the furnace cover 13. A vertical cylinder 2 runs through the middle of the top of the U-shaped frame 1. A furnace bottom 15 is provided at the bottom of the furnace cover 13. A distance sensor 9 is provided on one side of the bottom of the furnace bottom 15. A controller 10 is electrically connected to the bottom of the distance sensor 9. Electric cylinders 6 are installed on both sides of the U-shaped frame 1. A horizontal bar 5 is engaged at the output end of the electric cylinder 6. Two vertical rods 3 are provided on the inner side of the U-shaped frame 1. A collar 4 is fixedly connected to the bottom end of the vertical rod 3. A base 7 is fixedly connected to the bottom end of the U-shaped frame 1. Side frames 8 are fixedly connected to both sides of the base 7.

[0020] Specifically, the U-shaped frame 1 is a solid stainless steel structure with excellent load-bearing capacity, allowing the horizontal bar 5 on the U-shaped frame 1 to limit the movement of the furnace hood 13. The distance sensor 9 is an infrared distance sensor, located below the furnace hood 13, ensuring that the distance measured by the distance sensor 9 is the straight-line distance from the bottom of the furnace hood 13 to the top of the furnace bottom 15. This allows the distance sensor 9 to control the deviation between the furnace bottom 15 and the furnace hood 13 by measuring the distance between them. The electric cylinder 6 is horizontally positioned, allowing the horizontal bar 5 to move horizontally when pushed. The movement facilitates the contact between the rolling ball 14 on the horizontal bar 5 and the outer wall of the furnace hood 13. The vertical bar 3 can fix the collar 4 to the top of the U-shaped frame 1. At the same time, the inner diameter of the collar 4 is adapted to the outer diameter of the horizontal bar 5, so that the collar 4 can support and limit the horizontal bar 5. The vertical bar 3 can transmit the force exerted by the horizontal bar 5 on the collar 4 to the U-shaped frame 1, making the horizontal bar 5 more stable when moving laterally. The base 7 is an inclined support, so that the end of the base 7 can stand stably on the ground. At the same time, the side frame 8 extends the front and back of the base 7 outward, thereby further increasing the overall stability of the U-shaped frame 1.

[0021] Furthermore, the top of the furnace cover 13 is connected to the wire rope of the lifting structure, and the wire rope is movably connected to the vertical cylinder 2, so that the furnace cover 13 can be lifted smoothly, thereby facilitating the separation and docking of the furnace cover 13 and the furnace bottom 15.

[0022] Furthermore, the top of the vertical rod 3 is fixedly connected to the U-shaped frame 1, and the collar 4 is fixedly connected to the U-shaped frame 1 through the vertical rod 3. The collar 4 is suspended on the U-shaped frame 1 through the vertical rod 3 and remains stationary, which facilitates the horizontal bar 5 to pass through the collar 4 and contact the lug on the bell jar under the push of the electric cylinder 6.

[0023] Furthermore, the horizontal bar 5 is movably connected to the collar 4 via the electric cylinder 6. A rubber block 12 is fixedly connected to the end of the horizontal bar 5 away from the electric cylinder 6. The horizontal bar 5 is movably connected to the outer wall of the furnace cover 13 via the rubber block 12. The function of the rubber block 12 is to allow the ball 14 at the end of the horizontal bar 5 to roll more flexibly at the end of the horizontal bar 5.

[0024] Furthermore, a ball bearing 14 is movably embedded in the middle of the rubber block 12. The ball bearing 14 is slidably connected to the furnace cover 13 via the crossbar 5. The function of the ball bearing 14 is to reduce the frictional resistance generated by the end of the crossbar 5 against the outer wall of the furnace cover 13, which is more conducive to the raising and lowering of the furnace cover 13.

[0025] Furthermore, both sides of the inner wall of the U-shaped frame 1 are fixedly connected with inner diagonal braces 11. The function of the inner diagonal braces 11 is to reinforce the top of the U-shaped frame 1, so that the force transmitted from the vertical rod 3 to the U-shaped frame 1 can be smoothly distributed to the U-shaped frame 1, thereby increasing the stability of the horizontal bar 5.

[0026] Furthermore, the controller 10 is installed inside the edge of the furnace bottom 15. The controller 10 is electrically connected to two electric cylinders 6, enabling the controller 10 to control the electric cylinders 6, thereby facilitating the control of the crossbar 5 by the electric cylinders 6.

[0027] The usage method of this embodiment is as follows: When using this highly secure bell-shaped jar upper-level anti-foolproof device, the U-shaped frame 1 needs to be installed and fixed above the furnace hood 13 first. At the same time, the steel wire rope of the lifting structure connected to the furnace hood 13 needs to pass through the vertical cylinder 2 at the middle of the top of the U-shaped frame 1. When the furnace hood 13 is pulled upward by the steel wire rope of the lifting mechanism, the device can then be connected to an external power source to start the electric cylinder 6. Under the action of the controller 10, the electric cylinder 6 pushes the horizontal bar 5 towards the outer wall of the furnace hood 13, so that the rubber block 12 at the end of the horizontal bar 5 and the rolling ball 14 on the rubber block 12 can approach the furnace hood 13. Until it is in contact with the outer wall of the furnace hood 13, the rolling ball 14 on the rubber block 12 will roll against the rising outer wall of the furnace hood 13. When the furnace hood 13 is lowered by the wire rope of the hoisting mechanism, the distance sensor 9 on the furnace bottom 15 detects that the distance between the bottom of the furnace hood 13 and the top of the furnace bottom 15 has changed and the offset distance between the furnace hood 13 and the furnace bottom 15 exceeds the set value. It will send a signal to the controller 10, so that the controller 10 controls the electric cylinder 6 to extend and retract the crossbar 5, so that the crossbar 5 pushes the rolling ball 14 to adjust with the outer wall of the furnace hood 13, so that the furnace hood 13 can be successfully docked with the furnace bottom 15.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
