Description

Technical Field

[0001] This invention relates to linear track lifting device technology, and more specifically to a linear slide rail guide lifting device for heavy components. Background Technology

[0002] In many fields such as industrial production and logistics transportation, the lifting and movement of heavy components are common operational requirements. Linear track lifting devices, as a key type of mechanical equipment, undertake the important task of accurately and stably lifting heavy components to a designated position and enabling horizontal movement. They are widely used in industries such as automotive manufacturing, aerospace, and large-scale machining. However, existing linear track lifting devices have some problems in practical applications.

[0003] In existing linear track lifting devices, most sliding components lack flexible switching mechanisms in their support systems. Under no-load conditions, due to the lack of optimized support structures, some devices still use the same large-section support wheels as under heavy loads, leading to accelerated wear on the track and support wheels, shortening the equipment's lifespan, and increasing maintenance costs. For example, in automobile manufacturing workshops, frequent lifting operations cause severe wear on the track and support wheels, requiring regular replacement, which not only incurs significant costs but also impacts production schedules. Furthermore, during sliding, the limiting mechanism of the sliding components is poorly designed, failing to achieve precise contact with the track sidewalls. During sliding, the components are prone to misalignment or wobbling, resulting in unstable sliding, increased wear on the track and sliding components, and further increased maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a linear guide lifting device for heavy components, in order to solve the problem that the sliding components in the prior art lack a flexible switching mechanism; under no-load conditions, due to the lack of reasonable support structure optimization, some devices still use the same large cross-section support wheels as under heavy loads to contact the track, which leads to increased wear on the track and support wheels, shortens the service life of the equipment, and increases maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a linear slide rail guiding and lifting device for heavy components, comprising a track, wherein a plurality of first sliding components are slidably connected within the track, each first sliding component comprising a mounting frame, wherein a plurality of mounting slots are provided on the mounting frame, wherein a mounting plate is slidably connected within the mounting slots, wherein a first telescopic rod is fixedly connected to the bottom of the mounting plate and fixedly connected to the mounting slots, wherein a first spring is fixedly sleeved on the outer surface of the first telescopic rod and fixedly connected to the mounting slots, wherein first support wheels are rotatably connected to both sides of the mounting plate, wherein a second telescopic rod is fixedly connected to the bottom of the mounting plate, wherein a connecting frame is fixedly connected to the bottom end of the second telescopic rod, wherein a second spring is fixedly sleeved on the outer surface of the second telescopic rod and fixedly connected to the connecting frame, wherein a second support wheel is rotatably connected within the connecting frame, and a support plate is fixedly connected to the top of the mounting plate;

[0006] Limiting mechanisms are provided on both sides of the mounting frame to limit the mounting frame. A lifting frame is fixedly connected to the top of the support plate. A lifting rail is fixedly connected to the lifting frame. A lifting mechanism is provided on the lifting rail. A first moving mechanism connected to the rail is provided on the lifting frame to drive the lifting frame to move.

[0007] Furthermore, the limiting mechanism includes a mounting block fixedly connected to the mounting frame, a third telescopic rod fixedly connected to the mounting block, a limiting frame fixedly connected to one end of the third telescopic rod, a third spring fixedly sleeved on the outer surface of the third telescopic rod and fixedly connected to the limiting frame, and a limiting wheel rotatably connected inside the limiting frame.

[0008] Furthermore, the first moving mechanism includes a first rotating drive member fixedly connected to the top of the track, the output end of the first rotating drive member being fixedly connected to a first threaded rod rotatably connected to the track, the outer surface of the first threaded rod being threadedly engaged with the lifting frame, and a guide rod fixedly connected to the track being slidably connected to the lifting frame.

[0009] Furthermore, a push plate is fixedly connected to one side of the mounting frame, a collection box is fixedly connected to one end of the track, a telescopic drive is fixedly connected inside the collection box, an extrusion plate that is slidably connected to the collection box is fixedly connected to the output end of the telescopic drive, and a connecting pipe that is fixedly connected to the track is fixedly connected to one side of the collection box.

[0010] Furthermore, a filter screen is fixedly connected inside the collection box.

[0011] Furthermore, the lifting mechanism includes a plurality of second sliding components that are slidably connected to the lifting track. A connecting plate is fixedly connected to the top of the second sliding component, and a roller hoist is fixedly connected to the bottom of the connecting plate. A second moving mechanism connected to the track is provided on the connecting plate, and the second moving mechanism is used to drive the connecting plate to move.

[0012] Furthermore, the second moving mechanism includes a second rotation drive member fixedly connected to the track, and the output end of the second rotation drive member is fixedly connected to a second threaded rod rotatably connected to the lifting track. The outer surface of the second threaded rod is threadedly engaged with the connecting plate, and a guide rod fixedly connected to the track is slidably connected to the connecting plate.

[0013] Furthermore, multiple fixing blocks are fixedly connected to the track.

[0014] Compared with the prior art, the linear slide rail guiding and lifting device for heavy components provided by the present invention has the following advantages:

[0015] This linear guide rail lifting device ensures stable operation under varying loads thanks to its first sliding component. Under no-load conditions, the smaller cross-section second support wheel contacts the rail, reducing wear. Under heavy loads, the mounting plate presses down, causing the larger cross-section first support wheel to contact the rail, providing stable support. Simultaneously, the first and second support wheels form a dual-support structure, distributing weight, reducing stress on individual support wheels, and enhancing the device's adaptability to different loads, thus preventing safety hazards caused by uneven loads or swaying. Furthermore, the limiting mechanism's limiting wheel, under the action of the third telescopic rod and third spring, precisely fits against the rail sidewall, accurately limiting the first sliding component, preventing offset and swaying, and automatically compensating for wear gaps to maintain good contact at all times, ensuring stable sliding of the first sliding component and greatly improving the device's reliability and durability.

[0016] By injecting lubricating oil into the track, wear on the first sliding component is reduced. As the first sliding component moves, a pusher plate pushes the lubricating oil into a collection tank. A telescopic drive component drives a squeezing plate to compress the lubricating oil, forcing it through a filter screen to remove debris and impurities. The clean lubricating oil is then replenished through a connecting pipe to the other side of the track. This design ensures that the lubricating oil in the track is always clean, improving lubrication efficiency and effectively extending the service life of the first sliding component and the track. Furthermore, the automatic filtration and recycling reduces the frequency of manual lubricating oil changes, lowering maintenance workload. Good lubrication reduces component wear and failure rates, further reducing operating costs and improving production efficiency. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1 to 6As shown, the present invention provides a linear slide rail guiding and lifting device for heavy components, including a track 1, a plurality of first sliding components 2 slidably connected in the track 1, each first sliding component 2 including a mounting frame 3, a plurality of mounting slots 4 opened on the mounting frame 3, a mounting plate 5 slidably connected in the mounting slots 4, a first telescopic rod 6 fixedly connected to the bottom of the mounting plate 5 and fixedly connected to the mounting slot 4, a first spring 7 fixedly sleeved on the outer surface of the first telescopic rod 6 and fixedly connected to the mounting slot 4, first support wheels 8 rotatably connected to both sides of the mounting plate 5, a second telescopic rod 9 fixedly connected to the bottom of the mounting plate 5, a connecting frame 10 fixedly connected to the bottom end of the second telescopic rod 9, a second spring 11 fixedly sleeved on the outer surface of the second telescopic rod 9 and fixedly connected to the connecting frame 10, a second support wheel 12 rotatably connected in the connecting frame 10, and a support plate 13 fixedly connected to the top of the mounting plate 5;

[0029] Limiting mechanisms are provided on both sides of the mounting frame 3. The limiting mechanisms are used to limit the mounting frame 3. A lifting frame 14 is fixedly connected to the top of the support plate 13. A lifting rail 15 is fixedly connected to the lifting frame 14. A lifting mechanism is provided on the lifting rail 15. A first moving mechanism connected to the rail 1 is provided on the lifting frame 14. The first moving mechanism is used to drive the lifting frame 14 to move.

[0030] The limiting mechanism includes a mounting block 21 fixedly connected to the mounting frame 3. A third telescopic rod 22 is fixedly connected to the mounting block 21. One end of the third telescopic rod 22 is fixedly connected to a limiting frame 23. A third spring 24 fixedly sleeved on the outer surface of the third telescopic rod 22 and fixedly connected to the limiting frame 23 is fixedly connected to the limiting frame 23. A limiting wheel 25 is rotatably connected inside the limiting frame 23.

[0031] The first moving mechanism includes a first rotation drive 31 fixedly connected to the top of the track 1. The first rotation drive 31 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. The output end of the first rotation drive 31 is fixedly connected to a first threaded rod 32 that is rotatably connected to the track 1. The outer surface of the first threaded rod 32 is threadedly engaged with the lifting frame 14. A guide rod that is fixedly connected to the track 1 is slidably connected to the lifting frame 14. The first rotation drive 31 drives the first threaded rod 32 to rotate, and the first threaded rod 32 drives the lifting frame 14 to move.

[0032] The lifting mechanism includes multiple second sliding components 50 that are slidably connected to the lifting track 15. A connecting plate 51 is fixedly connected to the top of the second sliding component 50. The structure of the second sliding component 50 is the same as that of the first sliding component 2. A roller lifting machine 52 is fixedly connected to the bottom of the connecting plate 51. A second moving mechanism connected to the track 1 is provided on the connecting plate 51. The second moving mechanism is used to drive the connecting plate 51 to move.

[0033] The second moving mechanism includes a second rotation drive 53 fixedly connected to the track 1. The second rotation drive 53 is a servo motor controlled by a PLC programming program. The output end of the second rotation drive 53 is fixedly connected to a second threaded rod 54 rotatably connected to the track 1. The outer surface of the second threaded rod 54 is threadedly engaged with the connecting plate 51. A guide rod fixedly connected to the lifting track 15 is slidably connected to the connecting plate 51. The second rotation drive 53 drives the second threaded rod 54 to rotate, which in turn drives the connecting plate 51 and the second sliding assembly 50 to move. The connecting plate 51 drives the roller elevator 52 to move, thereby realizing the movement of the lifted items.

[0034] Multiple fixing blocks 61 are fixedly connected to track 1.

[0035] By fixing the track 1, the first sliding component 2 at the bottom of the lifting frame 14 is then installed on the track 1, and the first sliding component 2 on the connecting plate 51 is also installed on the track 1. The reel elevator 52 is then fixedly installed on the connecting plate 51. When the lifting device needs to lift a heavy object, the first moving mechanism first moves the lifting frame 14, and the second moving mechanism moves the connecting plate 51 on the lifting frame 14. When the lifting device moves without load, the second support wheel 12 on the connecting frame 10 contacts the track 1, thereby driving the lifting mechanism on the first sliding component 2. The frame 14 and connecting plate 51 move to prevent the first support wheel 8 with a larger cross-section from contacting the track 1, reducing wear on the track 1 and the first support wheel 8. When the winch 52 lifts the heavy object, the weight of the lifting frame 14 increases, and the lifting frame 14 begins to press down on the support plate 13 and mounting plate 5. The mounting plate 5 moves downward in the mounting groove 4, at which time the first telescopic rod 6 and the first spring 7 are compressed, and the second telescopic rod 9 and the second spring 11 are also compressed. At this time, the mounting plate 5 drives the first support wheel 8 to contact the track 1, achieving support. Then, the moving mechanism drives the first support wheel 8 to contact the track 1. The lifting frame 14 and connecting plate 51 move to move the lifted heavy object. During this movement, the limiting wheel 25 in the limiting frame 23 engages with the side wall of the track 1 to limit the sliding of the first sliding component 2, ensuring stable sliding of the first sliding component 2 within the track 1. Simultaneously, the elastic force of the third spring 24 and the action of the third telescopic rod 22 ensure precise engagement between the limiting wheel 25 on the limiting frame 23 and the side wall of the track 1, automatically compensating for gaps caused by wear and further improving the stability of the first sliding component 2 within the track 1. Meanwhile, lubricant is injected into the track 1. The lubricating oil lubricates the first sliding component 2 and reduces wear between the track 1 and the first sliding component 2, further improving the service life of the device. Through the cooperation of the first support wheel 8 and the second support wheel 12 on the first sliding component 2, the lifting device can use the small cross-section of the second support wheel 12 when unloaded to prevent the larger cross-section of the first support wheel 8 from contacting the track 1, reducing the wear of the first support wheel 8 on the track 1 and also reducing the wear of the first support wheel 8. When under heavy load, the simultaneous support of the first support wheel 8 and the second support wheel 12 improves the stability of the lifting device during movement.

[0036] Example 2

[0037] Based on Example 1, please refer to Figure 1 , Figure 3 and Figure 6As shown, a push plate 41 is fixedly connected to one side of the mounting frame 3, a collection box 42 is fixedly connected to one end of the track 1, a telescopic drive component 43 is fixedly connected inside the collection box 42, the telescopic drive component 43 is an electric telescopic rod, an extrusion plate 44 is fixedly connected to the output end of the telescopic drive component 43 and is slidably connected to the collection box 42, and a connecting pipe 45 is fixedly connected to the track 1 on one side of the collection box 42.

[0038] A filter screen 46 is fixedly connected inside the collection box 42.

[0039] By injecting lubricating oil into the track 1, the lubrication of the first sliding component 2 is improved. Simultaneously, as the first sliding component 2 slides within the track 1, it drives the push plate 41 to move. The push plate 41 then moves the lubricating oil within the track 1, pushing it into a collection box 42 on one side. Subsequently, the telescopic drive 43 within the collection box 42 drives the extrusion plate 44 downwards, extruding the lubricating oil within the collection box 42 and forcing it through a filter screen 46. The filter screen 46 filters out wear debris and impurities from the lubricating oil. The filtered lubricating oil is then introduced to the other side of the track 1 through a connecting pipe 45, replenishing the lubricating oil within the track 1. This process effectively filters the lubricating oil within the track 1, keeping it clean and improving its lubrication effect on the first sliding component 2.

[0040] Working principle:

[0041] Flexible switching between no-load and heavy-load support modes: Through the coordinated action of the first telescopic rod 6, the first spring 7, the second telescopic rod 9, and the second spring 11, the automatic switching of the support wheels between no-load and heavy-load conditions is achieved. During no-load movement, the larger-section first support wheel 8 does not contact the track 1, reducing wear on the track 1 and extending the service life of both the track 1 and the support wheels, thus reducing maintenance costs. When the winch hoist 52 lifts a heavy object, the weight of the lifting frame 14 increases, and the mounting plate 5 presses down, causing the larger-section first support wheel 8 to contact the track 1, providing more stable support and ensuring the safety and stability of the lifting device during heavy-load movement.

[0042] Dual support ensures stable operation: The first support wheel 8 and the second support wheel 12 on the first sliding component 2 cooperate with each other to form a dual support structure. This design not only enhances the adaptability of the lifting device under different load conditions, but also effectively distributes the weight, reduces the force on a single support wheel, and further improves the stability of the entire device during movement, avoiding safety hazards caused by uneven load or swaying.

[0043] The precise fit of the limiting mechanism ensures stable sliding: Under the action of the third telescopic rod 22 and the third spring 24, the limiting wheel 25 in the limiting mechanism can precisely fit against the side wall of the track 1. This design has several advantages: First, it precisely limits the sliding of the first sliding component 2, preventing the first sliding component 2 from shifting or shaking within the track 1, and ensuring that the lifting device moves stably along the predetermined track; second, the elasticity of the third spring 24 can automatically compensate for the wear gap caused by long-term use, always maintaining good contact between the limiting wheel 25 and the side wall of the track 1. Even if the track 1 or the limiting wheel 25 experiences slight wear, it can ensure that the sliding stability of the first sliding component 2 is not affected, greatly improving the reliability and durability of the device.

[0044] Automatic lubricant filtration maintains good lubrication: Injecting lubricant into the track 1 effectively improves the lubrication of the first sliding component 2 and reduces wear. The lubrication system, consisting of the collection box 42, telescopic drive 43, extrusion plate 44, filter screen 46, and connecting pipe 45, achieves automatic filtration and recycling of the lubricant. When the first sliding component 2 moves, the push plate 41 pushes the lubricant in the track 1 into the collection box 42. The telescopic drive 43 drives the extrusion plate 44 to extrude the lubricant, causing it to pass through the filter screen 46 to filter out wear debris and impurities. The filtered clean lubricant is then replenished by flowing through the connecting pipe 45 to the other side of the track 1. This design ensures that the lubricant in the track 1 remains clean at all times, improves the lubrication effect of the lubricant on the first sliding component 2, and effectively extends the service life of the first sliding component 2 and the track 1.

[0045] Reduced maintenance workload and lower operating costs: Because the lubrication system automatically filters and circulates lubricating oil, the frequency of manual oil changes is reduced, thus lowering maintenance workload. At the same time, good lubrication reduces wear between equipment components, lowering the failure rate, further reducing operating costs and improving production efficiency.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
