Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting mechanism technology, specifically a hydraulic cylinder lifting mechanism for a vertical industrial furnace. Background Technology
[0002] In numerous fields such as industrial production, logistics warehousing, and construction, hydraulic cylinder lifting mechanisms for vertical industrial furnaces are widely used as important vertical transportation equipment in scenarios such as lifting goods and installing and commissioning equipment. However, existing hydraulic cylinder lifting mechanisms for vertical industrial furnaces have many problems in actual use and urgently need improvement.
[0003] Chinese patent CN217398355U discloses a multi-cylinder synchronous lifting mechanism including a base, a lifting platform, multiple sets of hydraulic cylinders, and a hydraulic synchronous motor. This mechanism ensures the lifting platform does not tilt during lifting, effectively avoiding the "pressure buildup" or "vacuuming" phenomena of the hydraulic cylinders, and solving problems such as tilting, jamming, and damage when the lifting platform is under uneven load. However, this lifting mechanism uses a single drive method with a relatively fixed speed setting, making it difficult to flexibly adjust the lifting speed according to different work requirements, thus failing to meet the requirements of efficient operation. Furthermore, the lifting stroke of this mechanism is limited by the length of the piston rod inside the hydraulic cylinder, making it difficult to meet the requirements of stable conveying of large-stroke, heavy-load materials. In addition, the piston rod of this lifting mechanism has no limit or guide after extending from the hydraulic cylinder, which cannot ensure the stability during lifting.
[0004] Therefore, there is an urgent need for a hydraulic cylinder lifting mechanism for vertical industrial furnaces to achieve adjustable lifting speed of the lifting platform, improve the cylinder stroke and stability, and meet the needs of stable conveying of heavy-load materials. Utility Model Content
[0005] The purpose of this utility model is to provide a hydraulic cylinder lifting mechanism for a vertical industrial furnace, so as to solve at least one aspect of the problems and defects mentioned in the background art.
[0006] To achieve the above objectives, the first aspect of this utility model provides the following technical solution:
[0007] A hydraulic cylinder lifting mechanism for a vertical industrial furnace includes:
[0008] A frame, and mounting brackets and drive motors symmetrically arranged on both sides of the frame;
[0009] A lifting platform is installed at the bottom of the frame;
[0010] The mounting frame is provided with a limiting groove in the middle, and a hydraulic cylinder is provided at the top of the limiting groove. A hydraulic cylinder roller is provided inside the hydraulic cylinder. The top of the mounting frame is provided with several guide wheels and several fixed seats.
[0011] A plurality of traction ropes, one end of which is connected to a lifting platform, and the other end of which is connected to a plurality of fixed seats respectively. The traction ropes are coupled to a plurality of guide wheels and hydraulic cylinder rollers respectively.
[0012] The hydraulic cylinder lifting mechanism for a vertical industrial furnace according to this utility model has at least the following technical effects:
[0013] This vertical industrial furnace hydraulic cylinder lifting mechanism controls the extension and retraction speed of the piston rod inside the cylinder through drive motors on both sides of the frame. The cylinder rollers drive the traction ropes to move within the limiting grooves, thus achieving adjustable lifting speed and stable lifting, meeting the needs of different working conditions. Furthermore, the traction ropes, by winding around several guide wheels, significantly increase the cylinder stroke, enabling higher lifting heights compared to traditional vertical industrial furnace hydraulic cylinder lifting mechanisms, expanding the equipment's application range. Simultaneously, the extension and retraction movement of the cylinder rollers within the limiting grooves acts on several traction ropes, ensuring smooth operation of the lifting platform during ascent and descent, improving equipment reliability and safety. In addition, this lifting mechanism has a simple structure, achieving smooth lifting of the platform without complex transmission components, meeting the needs of stable conveying of large load materials.
[0014] As a further embodiment of this utility model: the plurality of guide wheels include a first guide wheel, a second guide wheel, a third guide wheel and a fourth guide wheel.
[0015] As a further embodiment of this utility model: the plurality of fixed seats include a first fixed seat and a second fixed seat.
[0016] As a further embodiment of this utility model: the plurality of traction ropes include a first traction rope and a second traction rope.
[0017] The system includes several guide wheels, including a first guide wheel, a second guide wheel, a third guide wheel, and a fourth guide wheel; several fixed seats, including a first fixed seat and a second fixed seat; and several traction ropes, including a first traction rope and a second traction rope. One end of the first traction rope is connected to the second fixed seat, and after passing through the hydraulic cylinder roller, the first guide wheel, and the second guide wheel, it is connected to the lifting platform. One end of the second traction rope is connected to the first fixed seat, and after passing through the hydraulic cylinder roller, the third guide wheel, and the fourth guide wheel, it is connected to the lifting platform.
[0018] When the lifting platform needs to rise, the drive motor starts rotating forward. The piston rod inside the hydraulic cylinder drives the bottom hydraulic cylinder roller to slowly extend and move towards the bottom along the limiting groove. The hydraulic cylinder roller presses the first traction rope and the second traction rope to move towards the bottom simultaneously. This causes the first traction rope to pass through the first and second guide wheels, and the second traction rope to pass through the third and fourth guide wheels, thus applying traction force to the lifting platform and achieving the lifting platform's ascent. When the lifting platform reaches the top and needs to descend, the drive motor starts rotating in reverse. The piston rod inside the hydraulic cylinder drives the bottom hydraulic cylinder roller to slowly retract and move towards the top along the limiting groove. The first traction rope passes through the first and second guide wheels, and the second traction rope passes through the third and fourth guide wheels, causing the traction ropes to slowly fall under the lifting platform's own weight, thus achieving the lifting platform's descent.
[0019] As a further embodiment of this utility model, some of the traction ropes are steel wire ropes.
[0020] As a further improvement of this utility model, a wire clamp is provided at one end of the wire rope.
[0021] As a further embodiment of this utility model: one end of the wire clamp is provided with a connector, and the wire rope is connected to the lifting platform through the wire clamp and the connector.
[0022] Because several of the traction ropes are steel wire ropes; one end of each steel wire rope is equipped with a wire clamp; the other end of each wire clamp is equipped with a connector. The steel wire rope is connected to the lifting platform through the wire clamp and the connector. The steel wire rope has high strength and good flexibility, and can withstand large tensile forces. It can effectively transmit the traction force generated by the hydraulic cylinder on the traction rope to the lifting platform, ensuring safe and reliable lifting even when carrying heavy loads. Furthermore, the wire clamp can firmly clamp the steel wire rope and adjust its length. The connector prevents the steel wire rope from loosening or slipping during the stress process, ensuring stable force transmission during the lifting platform's ascent and descent, thus improving the overall safety of the equipment.
[0023] As a further embodiment of this utility model, some of the traction ropes are chains.
[0024] As a further embodiment of this utility model: a chain connector is provided at one end of the chain, and the chain is connected to the lifting platform through the chain connector.
[0025] Because several traction ropes are chains; one end of the chain is equipped with a chain joint, and the chain is connected to the lifting platform through the chain joint; the chain is usually made of high-strength metal material, with excellent tensile strength and rigidity, and can withstand large tensile and impact forces, ensuring that the chain can safely and reliably transmit power, so as to meet the carrying requirements of heavier goods, and improve the carrying capacity and working reliability of the entire lifting system.
[0026] The second aspect of this utility model provides the following technical solution: a vertical industrial furnace, including a hydraulic cylinder lifting mechanism for the vertical industrial furnace.
[0027] By applying this hydraulic cylinder lifting mechanism for vertical industrial furnaces, especially vertical deposition furnaces, and utilizing its adjustable lifting speed, large lifting stroke, and stable lifting operation, the lifting speed can be precisely adjusted according to specific processes or requirements, ensuring that the deposition process meets process standards, thereby significantly improving deposition quality and product performance. Furthermore, this lifting mechanism can bear heavy workpieces, ensuring the stability and safety of the workpieces during the lifting process. Attached Figure Description

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0040] like Figure 1 and Figure 2The present invention, as shown in this embodiment, provides a hydraulic cylinder lifting mechanism for a vertical industrial furnace, comprising: a frame 1, and mounting frames 2 and a drive motor 3 symmetrically arranged on both sides of the frame 1; a lifting platform 4 is provided at the bottom of the frame 1; a limiting groove is provided in the middle of the mounting frame 2, a hydraulic cylinder 5 is provided at the top of the limiting groove, a hydraulic cylinder roller 6 is provided at the bottom of the hydraulic cylinder 5, and a plurality of guide wheels and a plurality of fixed seats are provided at the top of the mounting frame 2; a plurality of traction ropes, one end of which is connected to the lifting platform 4, and the other end of which is connected to the fixed seats respectively, and the traction ropes are coupled to the guide wheels and the hydraulic cylinder roller 6 respectively.
[0041] In use, when the lifting platform 4 needs to rise, the drive motor 3 starts rotating forward. The piston rod inside the cylinder 5 drives the cylinder roller 6 at its bottom to slowly extend and move towards the bottom along the limiting groove. The cylinder roller 6 presses several traction ropes to move towards the bottom at the same time, so that the traction ropes pass through several guide wheels and apply traction force to the lifting platform 4, thereby realizing the smooth rise of the lifting platform 4. When the lifting platform 4 rises to the top and needs to descend, the drive motor 3 starts rotating in reverse. The piston rod inside the cylinder 5 drives the cylinder roller 6 at its bottom to slowly retract and move towards the top along the limiting groove. Several traction ropes pass through several guide wheels, so that the traction ropes fall slowly under the weight of the lifting platform 4, thereby realizing the smooth descent of the lifting platform 4.
[0042] Specifically, the hydraulic cylinder lifting mechanism for this vertical industrial furnace controls the extension and retraction speed of the piston rod inside the hydraulic cylinder 5 through the drive motors 3 on both sides of the frame, and uses the hydraulic cylinder rollers 6 to drive the traction ropes to move within the limiting groove, thereby achieving adjustable lifting speed and stable lifting of the lifting platform 4 to meet the needs of different working conditions. Furthermore, the traction ropes, by winding around several guide wheels, greatly increase the hydraulic cylinder stroke, which can meet higher lifting height requirements compared to traditional hydraulic cylinder lifting mechanisms for vertical industrial furnaces, expanding the scope of application of the equipment. At the same time, the extension and retraction movement of the hydraulic cylinder rollers 6 within the limiting groove can simultaneously act on several traction ropes, thereby ensuring the smooth operation of the lifting platform during the rising and falling process, improving the reliability and safety of the equipment. In addition, the lifting mechanism has a simple structure and can achieve smooth lifting of the lifting platform 4 without complex transmission components, meeting the needs of stable conveying of large load materials.
[0043] Furthermore, such as Figure 1 As shown, the guide wheels include a first guide wheel 7, a second guide wheel 8, a third guide wheel 9 and a fourth guide wheel 10; the fixed seats include a first fixed seat 11 and a second fixed seat 12; and the traction ropes include a first traction rope 13 and a second traction rope 14.
[0044] Specifically, the system includes several guide wheels, including a first guide wheel 7, a second guide wheel 8, a third guide wheel 9, and a fourth guide wheel 10; several fixed seats, including a first fixed seat 11 and a second fixed seat 12; and several traction ropes, including a first traction rope 13 and a second traction rope 14. One end of the first traction rope 13 is connected to the second fixed seat 12, and after passing through the hydraulic cylinder roller 6, the first guide wheel 7, and the second guide wheel 8, it is connected to the lifting platform 4. One end of the second traction rope 14 is connected to the first fixed seat 11, and after passing through the hydraulic cylinder roller 6, the third guide wheel 9, and the fourth guide wheel 10, it is connected to the lifting platform 4.
[0045] When the lifting platform 4 needs to rise, the drive motor 3 starts rotating forward. The piston rod inside the cylinder 5 drives the cylinder roller 6 at its bottom to slowly extend and move towards the bottom along the limiting groove. The cylinder roller 6 presses the first traction rope 13 and the second traction rope 14 to move towards the bottom at the same time. The first traction rope 13 passes through the first guide wheel 7 and the second guide wheel 8, and the second traction rope 14 passes through the third guide wheel 9 and the fourth guide wheel 10. At the same time, the traction force is applied to the lifting platform 4, thereby realizing the smooth rise of the lifting platform 4. When the lifting platform 4 rises to the top and needs to descend, the drive motor 3 starts rotating in reverse. The piston rod inside the cylinder 5 drives the cylinder roller 6 at its bottom to slowly retract and move towards the top along the limiting groove. The first traction rope 13 passes through the first guide wheel 7 and the second guide wheel 8, and the second traction rope 14 passes through the third guide wheel 9 and the fourth guide wheel 10. The traction ropes fall slowly under the weight of the lifting platform 4, thereby realizing the smooth descent of the lifting platform 4.
[0046] In one embodiment, such as Figure 3 As shown, several traction ropes are steel wire ropes; one end of the steel wire rope is equipped with a steel wire clamp 15; one end of the steel wire clamp 15 is equipped with a connector 16, and the steel wire rope is connected to the lifting platform 4 through the steel wire clamp 15 and the connector 16.
[0047] Specifically, since several traction ropes are steel wire ropes; one end of the steel wire rope is equipped with a steel wire clamp 15; one end of the steel wire clamp 15 is equipped with a connector 16, and the steel wire rope is connected to the lifting platform 4 through the steel wire clamp 15 and the connector 16; the steel wire rope has high strength and good flexibility, and can withstand large tension, which can effectively transmit the traction force generated by the hydraulic cylinder 5 to the traction rope to the lifting platform 4, ensuring that the lifting function can be achieved safely and reliably when carrying heavy goods; and the steel wire clamp 15 can firmly clamp the steel wire rope and adjust the length of the steel wire rope, and then connect to the lifting platform 4 through the connector 16 to prevent the steel wire rope from loosening or slipping during the stress process, ensuring that the lifting platform 4 can stably transmit force during the rising and falling process, and improving the safety of the entire equipment.
[0048] In another embodiment, several traction ropes are chains; one end of the chain is provided with a chain joint (not shown in the figure), and the chain is connected to the lifting platform 4 through the chain joint.
[0049] Specifically, since several traction ropes are chains; one end of the chain is equipped with a chain joint, and the chain is connected to the lifting platform 4 through the chain joint; the chain is usually made of high-strength metal material, with excellent tensile strength and rigidity, and can withstand large tensile and impact forces, ensuring that the chain can safely and reliably transmit power, so as to meet the carrying requirements of heavier goods, and improve the carrying capacity and working reliability of the entire lifting system.
[0050] Additionally, it should be noted that a vertical industrial furnace includes a hydraulic cylinder lifting mechanism for the vertical industrial furnace.
[0051] Specifically, by applying the hydraulic cylinder lifting mechanism of this vertical industrial furnace to vertical industrial furnaces, especially vertical deposition furnaces, its adjustable lifting speed, large lifting stroke, and stable lifting operation can be utilized to precisely adjust the lifting speed according to specific processes or requirements, so that the deposition process meets process standards, thereby significantly improving deposition quality and product performance. Furthermore, this lifting mechanism can bear heavy workpieces, ensuring the stability and safety of the workpieces during the lifting process.
[0052] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
