Description

Technical Field

[0001] This utility model relates to the field of isolation door technology, and in particular to a double-chain isolation door. Background Technology

[0002] Isolation doors are devices that play an important role in industrial flue gas treatment and pipeline systems. They ensure the safe operation and effective control of the system by isolating or regulating the flow of media. They can operate safely for a long time in environments with high temperature, high air pressure, and a lot of dust accumulation. Isolation doors are usually installed in high-pressure cold air ducts such as the primary cold air inlet of coal mills, the outlet of primary air fans and blowers, as well as in low-pressure flue gas ducts such as the flue gas inlet and outlet of induced draft fans and dust collectors, to cut off the flow of media.

[0003] Currently, existing partition doors on the market have the following disadvantages:

[0004] Since isolation doors are usually installed in environments with a lot of smoke and dust, the transmission mechanism of existing isolation doors will be infiltrated by smoke and dust during long-term use, changing the transmission ratio between the transmission mechanisms. This can cause the isolation door to tilt or even jam during opening and closing, thus reducing the service life of the existing isolation doors. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a double-chain isolation door.

[0006] This utility model is achieved using the following technical solution: a double-chain isolation door, including a door panel, a support plate fixedly connected to the bottom of the door panel, a double-chain lifting assembly fixedly connected to the top edge of the support plate, a fixed frame slidably connected to both sides of the door panel, a fixed platform fixedly connected to the top of the fixed frame, and a lubrication assembly threadedly connected to the top of the fixed platform.

[0007] As a further improvement to the above solution, the double-chain lifting assembly includes a chain fixedly connected to the edge of the top of the pallet, a drive wheel meshing with the surface of the chain, a round rod fixedly connected to the surface of the drive wheel, a fixed frame rotatably connected to the surface of the round rod, a drive rod fixedly connected to one end of the round rod, a splined connection of one end of the drive rod to the output end of a servo motor, and a traction block fixedly connected to the other end of the chain.

[0008] The above technical solution, through the setting of traction blocks, achieves the balance of the weight of part of the door panel and the power required for the servo motor to operate the door panel opening and closing.

[0009] As a further improvement to the above solution, the lubrication assembly includes a fixed plate that is threadedly connected to the top of the fixed platform. An oil tank is fixedly connected to one side of the fixed plate, and seepage pipes are connected through the edges of both sides of the oil tank. One end of the seepage pipe is connected through to the top of the fixed frame.

[0010] Through the above technical solution, the lubricating oil in the oil tank can be slowly allowed to flow onto the chain by the setting of the seepage pipe.

[0011] As a further improvement to the above solution, sliders are provided on both sides of the traction block, and the surfaces of the sliders are slidably connected to the interior of the fixed frame.

[0012] The above technical solution, through the setting of the slider, avoids the traction block shaking from affecting the chain transmission, thus improving the stability of chain operation.

[0013] As a further improvement to the above solution, a motor box is fixedly connected to the surface of the servo motor, one end of the motor box is fixedly connected to one side of the fixed frame, and a transmission rod is connected through the surface of the motor box.

[0014] The above technical solution, through the setting of the motor box, achieves the purpose of protecting and supporting the servo motor.

[0015] As a further improvement to the above solution, a threaded opening is provided on one side of the oil tank, and a sealing cap is threadedly connected to the surface of the threaded opening.

[0016] The above technical solution, through the setting of the sealed cover, enables users to apply lubricating oil to the oil tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a double-chain lifting assembly. When using the double-chain isolation door, the user connects the servo motor to an external power source, causing the transmission rod to drive the two transmission wheels to rotate synchronously. This causes the double chains to pull the two ends of the support plate synchronously, allowing the support plate to slide along the fixed frame, thereby opening or closing the isolation door. The transmission wheels and chains are meshed together to prevent slippage. Furthermore, the chains can still work effectively in humid and dusty environments, ensuring that the double-chain isolation door maintains an accurate average transmission ratio even after long-term use, thus preventing the double-chain isolation door from tilting or jamming.

[0019] This invention incorporates a lubrication component, allowing users to add lubricating oil to the oil tank through the threaded port when using the double-chain isolation door. When stationary, the lubricating oil in the tank slowly drips through the seepage pipe onto a portion of the chain, and during chain operation, it is applied to the drive wheel and other parts of the chain. This enables the double-chain isolation door to continuously lubricate the chain, further improving its service life. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-4This embodiment of a double-chain isolation door includes a door panel 1, a support plate 2 fixedly connected to the bottom of the door panel 1, and a double-chain lifting assembly 3 fixedly connected to the top edge of the support plate 2. By setting the double-chain lifting assembly 3, when using the double-chain isolation door, the user connects the servo motor 305 to an external power source, causing the transmission rod 304 to drive the two transmission wheels 302 to rotate synchronously. This causes the double chains 301 to pull the two ends of the support plate 2 synchronously, causing the support plate 2 to drive the door panel 1 to slide along the fixed frame 4, thereby opening or closing the isolation door. The transmission wheels 302 and the chains 301 are meshed together to prevent slippage. Furthermore, the chains 301 can still work effectively in humid and dusty environments, ensuring the double-chain isolation door can maintain its functionality even after long-term use. To maintain an accurate average transmission ratio, the double-chain isolation door is prevented from tilting or jamming. A fixed frame 4 is slidably connected to both sides of the door panel 1, and a fixed platform 5 is fixedly connected to the top of the fixed frame 4. A lubrication assembly 6 is threadedly connected to the top of the fixed platform 5. By setting the lubrication assembly 6, when using the double-chain isolation door, the user adds lubricating oil to the oil tank 602 through the threaded port. When stationary, the lubricating oil in the oil tank 602 slowly drips through the seepage pipe 603 onto a portion of the chain 301, and during the operation of the chain 301, it is applied to the transmission wheel 302 and other parts of the chain 301. This allows the double-chain isolation door to continuously lubricate the chain 301, further improving the service life of the double-chain isolation door.

[0029] The double-chain lifting assembly 3 includes a chain 301 fixedly connected to the top edge of the pallet 2. A transmission wheel 302 is meshed with the surface of the chain 301. A round rod 303 is fixedly connected to the surface of the transmission wheel 302. A fixed frame 4 is rotatably connected to the surface of the round rod 303. A transmission rod 304 is fixedly connected to one end of the round rod 303. One end of the transmission rod 304 is splinedly connected to the output end of the servo motor 305. A traction block 306 is fixedly connected to the other end of the chain 301. By setting the traction block 306, the weight of part of the door panel 1 is balanced, and the power required for the servo motor 305 to operate the door panel 1 is reduced.

[0030] The lubrication assembly 6 includes a fixed plate 601 that is threadedly connected to the top of the fixed platform 5. An oil tank 602 is fixedly connected to one side of the fixed plate 601. A seepage pipe 603 is connected through the edges of both sides of the oil tank 602. One end of the seepage pipe 603 is connected through the top of the fixed frame 4. Through the seepage pipe 603, the lubricating oil in the oil tank 602 can slowly flow onto the chain 301.

[0031] The traction block 306 is provided with sliders 7 on both sides. The surface of the sliders 7 is slidably connected to the inside of the fixed frame 4. By setting the sliders 7, the shaking of the traction block 306 is prevented from affecting the transmission of the chain 301, thus improving the stability of the chain 301 operation.

[0032] A motor box 8 is fixedly connected to the surface of the servo motor 305. One end of the motor box 8 is fixedly connected to one side of the fixed frame 4. A transmission rod 304 is connected through the surface of the motor box 8. The purpose of the motor box 8 is to protect and support the servo motor 305.

[0033] The oil tank 602 has a threaded opening on one side, and a sealing cover 9 is threadedly connected to the surface of the threaded opening. The sealing cover 9 allows the user to add lubricating oil to the oil tank 602.

[0034] The implementation principle of a double-chain isolation door in this application embodiment is as follows: When using the double-chain isolation door, the user connects the servo motor 305 to an external power source and powers it on, causing the transmission rod 304 to drive the two transmission wheels 302 to rotate synchronously, causing the double chains 301 to pull the two ends of the support plate 2 synchronously, causing the support plate 2 to drive the door panel 1 to slide along the fixed frame 4, thereby opening or closing the isolation door. The transmission wheels 302 and the chains 301 are connected by meshing and will not slip. At the same time, the chains 301 can still work effectively in a humid and dusty environment, so that the double-chain isolation door can maintain an accurate average transmission ratio during long-term use. The user adds lubricating oil to the oil tank 602 through the threaded port. When the oil tank 602 is stationary, the lubricating oil in the oil tank 602 slowly drips onto a part of the chains 301 through the seepage pipe 603, and is spread to the transmission wheels 302 and other parts of the chains 301 during the operation of the chains 301.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
