Description

Technical Field

[0001] This invention relates to the field of overhead conveying technology, specifically to an overhead conveying device for lubricating oil production. Background Technology

[0002] With the continuous improvement of the automation level of lubricant production, the material conveying system of its production line is becoming more and more complex, and the application of various suspended conveying equipment is increasing. The daily tasks of online material handling and transfer are also becoming more and more arduous.

[0003] Suspended conveyor systems are typically used to smoothly load and transport production materials such as material barrels and additive packages on straight tracks. However, when entering curved sections, the equipment often needs to carry the materials along an arc-shaped trajectory to complete cross-station transfers. During this process, workers rely on the conveyor's own weight for centering or simple elastic limits to maintain the material's posture. If the material swings significantly outward due to centrifugal inertia at the curve, it may cause the materials to collide with each other, detach from the hooks, or even damage the conveyor track, severely affecting production flow. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a material suspension conveying device for lubricating oil production, which solves the problem that the material sways violently due to inertia when entering a curve, affecting conveying stability and production efficiency.

[0007] Preferably, the linkage transmission assembly includes a first link and a second link, one end of the first link is hinged to the force-bearing connection part, the other end of the first link is hinged to one end of the second link, and the other end of the second link is hinged to the rotary trigger.

[0008] Preferably, the damping energy absorption assembly includes a damping drive wheel meshing with a rotating trigger and a damping base fixed on a load-bearing trolley. The damping base is provided with a first damping cavity and a second damping cavity. A damping hole is opened between the first damping cavity and the second damping cavity. A rotating shaft is coaxially connected to the damping drive wheel, and the rotating shaft is driven to a pressing member extending into the first damping cavity.

[0009] Preferably, a reflux hole is provided on the inner wall of the first damping cavity, and a one-way diaphragm is provided at the reflux hole.

[0010] Preferably, the suspension assembly includes a support part and a movable part. The support part is connected to a rotary trigger, and the movable part is slidably connected to the support part.

[0013] Preferably, the surface of the sealing sphere is provided with an arc-shaped throttling groove.

[0014] Preferably, the bottom of the load-bearing trolley is provided with a clearance groove for the suspension assembly to swing.

[0015] This invention provides a suspended material conveying device for lubricant production. It has the following advantages:

[0016] 1. This invention solves the problem of large-scale swaying caused by inertia when materials enter a curved conveying path in the prior art by using a deflection drive component, a suspension component and a trigger component on the side of the conveying track. This achieves the effect of pre-deflecting the suspended material to the inside of the curve to counteract the outward swaying tendency, thereby improving the stability of the conveying process.

[0017] 2. The present invention uses a damping energy absorption component composed of an extrusion part, a damping hole and a return hole, which enables the suspension component to efficiently dissipate impact energy through fluid viscosity when it swings outward, effectively avoiding the elastic rebound phenomenon that is easy to occur in traditional spring buffers.

[0018] 3. The present invention uses a retractable suspension support part of an annular piston and transmits pressure changes to the pressure chamber between the slidingly fitted upper and lower connecting plates through a fluid hose. This allows the height of the force-bearing connection part to be automatically changed according to the different weights of the loaded materials to adjust the initial transmission angle. This effectively avoids the problem of insufficient or excessive deflection when dealing with materials of different weights with a fixed deflection angle, and greatly improves the adaptability of the conveying equipment to variable load conditions.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to the appendix. Figure 1 - Appendix Figure 5 This is the first embodiment of the present invention. This embodiment provides a material suspension conveying device for lubricating oil production, including a conveying track extending along a preset path and a load-bearing trolley 100 slidably disposed on the conveying track via a set of rollers. The load-bearing trolley 100 moves along the track direction as the entire movable load-bearing component. A suspension assembly 200 is disposed at the bottom of the load-bearing trolley 100. The suspension assembly 200 can deflect relative to the load-bearing trolley 100. Its lower end is used to hang materials. The suspension assembly 200 is generally in the shape of a long rod.

[0030] The deflection drive assembly 300 is integrally mounted on the carrying trolley 100 and forms a transmission connection with the upper end of the suspension assembly 200. A trigger 310 is fixedly installed on the outer or inner wall of the conveying track. The trigger 310 is set at a preset position before the carrying trolley 100 enters the curved section of the track. The trigger 310 can be a wedge-shaped block that gradually protrudes along the extension direction of the track, or a cam plate with a spiral rising working surface. When the carrying trolley 100 moves along the track and reaches the preset position, the inclined surface or protrusion of the trigger 310 will partially contact the deflection drive assembly 300 and apply a squeezing action. This squeezing action is received by the deflection drive assembly 300 and converted into a driving force to drive the suspension assembly 200 to actively deflect a preset angle around its rotation axis in a preset direction, such as a horizontal direction towards the inside of the curve.

[0031] Please see the appendix Figure 2 - Appendix Figure 4 In addition, the damping energy absorption component 400 is mounted on the load-bearing trolley 100 and forms a transmission connection with the deflection drive component 300. When the suspension component 200 is deflected or swayed by an external force impact, the damping energy absorption component 400 can apply resistance to the offset movement of the suspension component 200, thereby achieving motion damping during the offset process and using the swing tendency to pre-cancele.

[0032] Please see the appendix Figure 1 and attached Figure 5In this embodiment, the carrying trolley 100 carries the material suspended by the suspension assembly 200 along a straight track toward the curve area. Before entering the curve, the trigger 310 first contacts and squeezes the deflection drive assembly 300. The deflection drive assembly 300 then moves, causing the suspension assembly 200 to tilt in advance toward the inside of the curve. When the carrying trolley 100 enters the curve, the material tends to swing outward due to centrifugal inertia. Since the suspension assembly 200 has been tilted inward in advance, the outward swinging tendency of the material is offset by the pre-deflection angle, rather than directly producing a large sway. At the same time, any further deflection action of the suspension assembly 200 during this process will be transmitted to the damping energy absorption assembly 400 through the deflection drive assembly 300. The damping energy absorption assembly 400 absorbs the impact energy and slows down the swing speed.

[0033] Through the above-described combined structure, this embodiment effectively solves the problem of large-scale swaying of materials due to inertia during curved conveying, and improves the stability of the conveying process. Compared with the traditional solution that only uses spring buffer, the damping energy absorption component 400 in this embodiment does not produce elastic rebound after absorbing energy, thus avoiding secondary swaying.

[0034] Example 2, please refer to the appendix. Figure 2 - Appendix Figure 3 This is the second embodiment of the present invention. Based on the first embodiment, the deflection drive assembly 300 further includes a rotary trigger 320. The rotary trigger 320 is rotatably connected to the carrying trolley 100 via a rotating shaft or bearing. It can rotate around its own axis. The rotary trigger 320 is generally in the shape of a disc or a sleeve. The upper end of the suspension assembly 200 is fixedly connected to the bottom of the rotary trigger 320 by welding or keying, so that the suspension assembly 200 and the rotary trigger 320 rotate synchronously.

[0035] Please see the appendix Figure 2 The deflection drive assembly 300 also includes a force-bearing connection 330, which is configured to be slidably installed in the guide groove of the carrying trolley 100 in the horizontal direction. The force-bearing connection 330 is generally in the shape of a long strip slider, and a freely rotatable roller is installed at the end facing the trigger 310 to reduce the sliding friction when in contact with the trigger 310. The trigger 310 is fixedly installed on the side of the track and has a wedge-shaped working surface that gradually protrudes inward along the traveling direction of the carrying trolley 100. When the carrying trolley 100 moves, the wedge-shaped working surface slides into contact with the roller at the end of the force-bearing connection 330 and gradually pushes the force-bearing connection 330 into the carrying trolley 100. The maximum sliding displacement of the force-bearing connection 330 is limited by the end face of the guide groove of the carrying trolley 100.

[0036] Please see the appendix Figure 2 and attached Figure 3To convert the horizontal linear motion of the force-bearing connection 330 into the rotational motion of the rotary trigger 320, a linkage transmission assembly 340 is provided between the force-bearing connection 330 and the rotary trigger 320. The linkage transmission assembly 340 includes a first link 341 and a second link 342. One end of the first link 341 is hinged to the side of the force-bearing connection 330 through a first hinge shaft. The other end of the first link 341 is hinged to one end of the second link 342 through a second hinge shaft. The other end of the second link 342, that is, the end away from the first link, is hinged to the lug on the rotary trigger 320 that is off-center from its rotation center through a third hinge shaft.

[0037] Thus, the force-bearing connection 330, the first connecting rod 341, the second connecting rod 342, and the rotary trigger 320 together constitute a linkage mechanism. In addition to adopting two hinged connecting rods, the linkage transmission assembly 340 can also adopt a crank-slider form with a single bent rod and a sliding groove.

[0038] When the force-bearing connection 330 is pushed and slid by the trigger member 310, it drives the first link 341 to move. The first link 341 then pushes the second link 342, and the second link 342 pulls the lug of the rotating trigger member 320, thereby driving the rotating trigger member 320 to rotate around its axis. At the same time, there is a corresponding relationship between the rotation angle of the rotating trigger member 320 and the sliding displacement of the force-bearing connection 330.

[0039] Please see the appendix Figure 2 In this embodiment, the wedge-shaped working surface of the track-side trigger 310 and the sliding engagement of the roller in the force-bearing connection 330 directly drive the linkage transmission assembly 340 to deflect the rotary trigger 320. This process relies entirely on the relative motion generated by the movement of the carrying trolley 100 itself, eliminating the need for motors, cylinders, sensors, or controllers, significantly reducing costs and failure rates, and making it particularly suitable for harsh industrial environments.

[0040] Please see the appendix Figure 3 The articulated linkage mechanism formed by the first link 341 and the second link 342 converts the short horizontal linear displacement of the force-bearing connection part 330 into a larger angle of rotational output of the rotary trigger 320. The link length ratio can be set to amplify the input thrust and reduce the contact pressure between the trigger 310 and the roller, thereby reducing wear and extending the service life of the component.

[0041] The rotation angle of the rotating trigger 320 and the sliding displacement of the force-bearing connection part 330 are adjustable. For example, by adjusting the length of the connecting rod or the position of the hinge point, different deflection angles can be preset for different curve radii, making it highly adaptable.

[0042] Example 3, please refer to the appendix. Figure 3 - Appendix Figure 4This is the third embodiment of the present invention. Based on any of the above embodiments, the damping energy absorption assembly 400 further includes a damping transmission wheel 410 that meshes with the rotating trigger 320. The damping transmission wheel 410 is a spur gear that meshes with the gear segment provided on the outside of the rotating trigger 320. The damping energy absorption assembly 400 also includes a damping base 420 that is fixed to the bearing trolley 100 by bolts. The damping base 420 is injection molded from aluminum alloy or engineering plastic. The outside of the damping base 420 is provided with a mounting flange that mates with the bearing trolley 100. The flange is provided with four evenly distributed through holes for bolts to pass through.

[0043] Specifically, the damping base 420 is provided with a first damping cavity 421 and a second damping cavity 422. The two cavities are arranged side by side and filled with fluid media such as high viscosity silicone oil. A damping hole 423 is provided on the partition plate between the first damping cavity 421 and the second damping cavity 422. The diameter of the damping hole 423 is much smaller than the cross-sectional size of the cavity. It serves as the main throttling channel for the fluid medium to flow between the two cavities. The shape of the damping hole 423 can be a circular through hole, a narrow slot, or a perforated plate composed of multiple micro holes.

[0044] A rotating shaft 411 is coaxially connected to the center of the damping drive wheel 410. The rotating shaft 411 is rotatably mounted on the damping base 420 through a bearing. One end of the rotating shaft 411 extends into the interior of the damping base 420 and is connected to the extrusion member 430.

[0045] Please see the appendix Figure 4 In this embodiment, the extruder 430 is an eccentric cam installed at the end of the rotating shaft 411. The eccentric cam extends into the first damping cavity 421. When the rotating trigger 320 rotates due to the deflection of the suspension assembly 200, it drives the damping transmission wheel 410 to rotate. The damping transmission wheel 410 drives the rotating shaft 411 to rotate. The rotating shaft 411 then drives the extruder 430 to rotate and extrude the solution in the first damping cavity 421. When the extruder 430 extrudes into the first damping cavity 421, the fluid medium inside the cavity is subjected to high pressure and can only flow slowly into the second damping cavity 422 through the narrow damping hole 423. The fluid generates huge flow resistance when flowing through the damping hole 423. This resistance reacts to the rotating trigger 320 through the extruder 430, the rotating shaft 411, and the damping transmission wheel 410, thereby applying damping to the deflection movement of the suspension assembly 200 and absorbing the swaying energy.

[0046] To achieve unidirectional damping characteristics, a return hole 424 is also provided on the inner wall of the first damping cavity 421. The diameter of the return hole 424 is larger than that of the damping hole 423. A unidirectional diaphragm 425 is provided at the return hole 424. The unidirectional diaphragm 425 is made of flexible rubber material and is in the shape of a circular or square thin sheet. The unidirectional diaphragm 425 is configured as a one-way valve structure: when the extruder 430 extrudes the fluid medium in the first damping cavity 421, the high-pressure medium presses the unidirectional diaphragm 425 tightly against the end face of the return hole 424, sealing the return hole 424 and forcing the medium to flow only through the damping hole 423; when the extruder 430 moves in the opposite direction and a negative pressure is generated in the first damping cavity 421, the medium pressure on one side of the external second damping cavity 422 pushes the unidirectional diaphragm 425 open, and the medium can quickly flow back to the first damping cavity 421 through the return hole 424.

[0047] It should be noted that a thin, elastic plate with a cross-shaped or star-shaped slit is installed at the damping orifice 423. Under normal pressure, the slit only opens slightly, providing throttling for the small orifice; under high pressure, the plate deforms, the slit opening widens, and the flow area increases accordingly. When the suspension assembly 200 encounters a sudden and severe impact, and the instantaneous speed of the rotating trigger 320 far exceeds that of normal curve conditions, causing the extrusion component 430 to exert extremely high impact pressure on the medium, the damping orifice 423 automatically expands, releasing the medium and limiting the damping effect within a safe range to prevent damage to components.

[0048] Please see the appendix Figure 4 Furthermore, a flexible compression layer is fixedly installed inside the second damping cavity 422. This flexible compression layer is a structure such as an air bladder with memory characteristics. When a large amount of medium flows into the second damping cavity 422 through the damping hole 423, the flexible compression layer is compressed, absorbing part of the medium's volume. When the medium flows back, the flexible compression layer expands, assisting in pushing the medium back, ensuring fluid volume balance and compensating for volume changes caused by temperature variations. Through this structure, the suspension assembly 200 is provided with unidirectional damping characteristics to resist deflection. This damping force is generated by a viscous fluid, has no elastic rebound, and can efficiently dissipate impact energy.

[0049] Example 4, please refer to the appendix. Figure 5 - Appendix Figure 8This is the fourth embodiment of the present invention. Based on the previous embodiments, the suspension assembly 200 is further characterized by being a retractable buffer structure, comprising a support portion 210 and a movable portion 220. The upper end of the support portion 210 is fixedly connected to the rotary trigger 320. The interior of the support portion 210 is hollow, forming a vertically extending groove with a circular cross-section. The upper end of the movable portion 220 is provided with an annular piston 230, which is slidably and sealingly disposed within the groove. At least one O-ring is embedded on the outer circumferential surface of the annular piston 230 to ensure a sliding seal with the inner wall of the groove. The lower end of the movable portion 220 extends downward from the support portion 210, and a material hook is fixed at its bottom. The material hook has an anti-disengagement structure and an elastic baffle at its opening. An elastic reset member is also connected between the support portion 210 and the movable portion 220. The elastic reset member is a compression spring sleeved on the outside of the movable portion 220, providing a preload force to push the movable portion 220 upward.

[0050] When materials of different weights are hung on the hook, the movable part 220 slides downward relative to the support part 210 at different rates, and the annular piston 230 also compresses the gas or liquid medium in the groove. The medium in the groove is hydraulic oil or compressed air.

[0051] Specifically, it includes an upper connecting plate 510 and a lower connecting plate 520 that slides vertically with the upper connecting plate 510. The lower connecting plate 520 is slidably mounted on the load-bearing trolley 100. A dovetail groove or T-groove sliding guide structure is provided between the upper connecting plate 510 and the lower connecting plate 520. A sealed pressure chamber 521 is opened inside the lower connecting plate 520. The pressure chamber 521 is connected to the upper sliding groove of the support part 210 of the suspension assembly 200 through a flexible fluid hose. The fluid medium filled in the sliding groove can flow into the pressure chamber 521 through the flexible fluid hose.

[0052] Please see the appendix Figure 6 and attached Figure 7 When a heavy load is mounted, the annular piston 230 compresses the medium in the groove, increasing the medium pressure. This pressure is then transmitted to the pressure chamber 521 via a flexible fluid hose. The increased pressure in the pressure chamber 521 pushes the upper connecting plate 510 to slide upward relative to the lower connecting plate 520. This change in height alters the contact position between the trigger 310 and the force-bearing connection 330, thereby affecting the initial transmission angle of the linkage transmission assembly 340. Ultimately, this allows the suspension assembly 200 to obtain different pre-deflection angles when subjected to the same trigger 310 pressure. A larger pre-deflection angle corresponds to a heavier load, while a smaller load results in a lower medium pressure, causing the upper connecting plate 510 to descend and the pre-deflection angle to decrease.

[0053] Please see the appendix Figure 8Furthermore, to prevent backflow of the medium when the suspension assembly 200 is impacted, which could cause a sudden change in height, a sealing element 540 is fixed inside the inlet of the pressure chamber 521. A sealing ball 541 is movable inside the sealing element 540, and a limiting block 542 is fixed on one side of the sealing element 540. Under normal conditions, when the medium flows in from the flexible fluid hose, it pushes the sealing ball 541 to the position blocked by the limiting block 542, and the medium can flow through the gap between the ball and the sealing element 540. When the suspension assembly 200 is impacted upwards, and the medium attempts to flow back from the pressure chamber 521 to the slide, the reverse fluid pressure pushes the sealing ball 541 to the other side of the sealing element 540, forming a seal and blocking the backflow.

[0054] As a further preferred embodiment, the surface of the sealing sphere 541 is provided with an arc-shaped throttling groove 543. The arc-shaped throttling groove 543 extends along the surface of the sealing sphere 541 in a spiral or straight line form. Even if the sealing sphere 541 is in the position of blocking backflow, a small amount of medium can still slowly flow back to the slide through the arc-shaped throttling groove 543, allowing the suspension assembly 200 to gradually return to the balance height after long-term operation and avoiding long-term locking.

[0055] Based on the foregoing embodiments, the general working principle of the device of the present invention is given below:

[0056] Mode 1: When transporting the same batch of lubricating oil materials of the same weight, the force-bearing connection 330 is set as an integral rigid slider that is not retractable. The worker hangs the material on the hook of the suspension component 200. Because the structure is fixed, the initial transmission angle of the linkage transmission component 340 and the height of the force-bearing connection remain constant. For this batch of materials of fixed weight, an optimal pre-deflection angle is pre-calibrated on the mechanical structure, which is suitable for stable assembly line operations of large batches and single varieties.

[0057] Mode 2: When the production line faces mixed production and the loads of materials of varying weights, the force-bearing connection 330 is composed of a relatively sliding upper connecting plate 510 and a lower connecting plate 520. After loading materials of different weights, the weight of the materials presses down on the annular piston 230 inside the suspension assembly 200, squeezing the fluid medium. The pressurized medium flows into the pressure chamber 521, pushing the upper connecting plate 510 upward and extending it. The heavier the material, the higher the upper connecting plate 510 is lifted, thereby dynamically changing the initial transmission angle and automatically realizing adaptive adjustment of heavy objects corresponding to a large pre-deflection angle and light objects corresponding to a small pre-deflection angle.

[0058] When the carrying trolley 100 carries the material and moves smoothly along the conveying track, and is about to enter the curved section, when the carrying trolley moves to the preset position, the trigger 310 on the side of the track will contact and squeeze the roller at the end of the force-bearing connection 330, pushing it into the carrying trolley 100. The sliding of the force-bearing connection 330 is converted into a driving force through the linkage transmission assembly 340, driving the rotating trigger 320 to rotate around the axis. This causes the suspension assembly 200, which is fixed to the rotating trigger 320, to deflect to the inside of the curve by a preset angle in advance.

[0059] When the trolley and material officially enter the curve, the material is subjected to centrifugal inertial force, which causes it to swing outward. Since the suspension assembly 200 has been tilted inward before entering the curve, the outward swinging tendency of the material is exactly canceled out by the pre-deflection angle, thus avoiding direct large-scale shaking of the material. In addition, the rotating trigger 320 will drive the damping transmission wheel 410 and the rotating shaft 411 to rotate, which in turn drives the extruder 430 in the first damping cavity 421 to extrude the fluid medium, forcing the medium to flow only through the damping hole 423 to the second damping cavity 422. When the medium flows through the damping hole 423, it generates resistance. This resistance reacts to the suspension assembly 200, converting and dissipating the kinetic energy of its swaying. This process relies on fluid damping to absorb energy, eliminating the secondary elastic rebound phenomenon that is easy to produce in traditional spring buffers.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
