Description

Technical Field

[0001] This invention relates to the field of suspended conveying devices, and more specifically, to a suspended intelligent truss conveying device. Background Technology

[0002] Suspended truss conveyors are essential equipment for automated material handling in industrial workshops, primarily used for the transfer and transport of materials on production lines. Traditional suspended conveyor systems generally employ a rigid, integrated truss structure, including a horizontal drive mechanism that moves materials horizontally and a longitudinal drive mechanism that moves materials vertically. The components of the longitudinal drive mechanism often feature a fixed, rigid extension design, resulting in significant spatial adaptation deficiencies in practical applications.

[0003] When this type of rigid truss device is used for longitudinal material conveying, the components of the longitudinal drive mechanism will extend upward with the conveying stroke, which can easily cause spatial interference with the workshop roof, top pipelines and steel structure of the factory. However, the longitudinal installation height of most production workshops is limited, making it inconvenient to reserve sufficient space for the longitudinal moving components of the rigid truss. This makes it inconvenient for the device to be installed and used in low-ceilinged factories, limiting its application scenarios. Therefore, we propose a suspended intelligent truss conveying device to solve the above-mentioned problems. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] Traditional suspended truss conveyor systems often employ a fixed, rigid extension design for their longitudinal drive mechanism components. When conveying materials longitudinally, these components extend upwards with the conveying stroke, easily causing spatial interference with workshop roofs, overhead pipelines, and the steel structure of the factory. Furthermore, most production workshops have limited longitudinal installation height, making it inconvenient to reserve sufficient space for the longitudinal moving components of the rigid truss. This makes the system unsuitable for installation and use in low-ceilinged factory buildings, thus limiting its application scenarios.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A suspended intelligent truss conveying device includes an arc-shaped curved track, a horizontal long track, a vertical short track, and several identical chain links. Each chain link includes a chain link mechanism and a chain plate mechanism. The chain link mechanism includes an H-shaped chain link component. Both ends of the H-shaped chain link component have connecting grooves and a set of shaft holes. A spline shaft hole is provided on the H-shaped chain link component located between two of the connecting grooves. A spline push rod is slidably connected inside the spline shaft hole, and a ball head is fixedly installed on the top of the spline push rod. A support spring is also sleeved on the spline push rod located between the spline shaft hole and the ball head. The bottom of the spline push rod extends through to the bottom of the H-shaped chain link component, and an H-shaped limiting component is fixedly installed at the bottom end of the spline push rod by bolts. The H-shaped limiting component has four symmetrically arranged snap-fit ​​ends. An inlay opening is also provided on the H-shaped chain link component corresponding to the snap-fit ​​end position.

[0009] Furthermore, the chain plate mechanism includes a chain link plate, one end of which is embedded in one of the connecting grooves. A connecting shaft is fixedly sleeved inside the chain link plate, and both ends of the connecting shaft extend to the outside of the H-shaped chain link. A set of gears is fixedly sleeved on the connecting shaft located outside the H-shaped chain link. The inlay opening and the corresponding tooth at the bottom of the gear are engaged by the snap-fit ​​end. Limiting protrusions are fixedly connected at equal intervals on the outer wall of the connecting shaft located at the connection between the gear and the chain link plate. A bearing is sleeved on the connecting shaft located between the gear and the chain link plate. The connecting shaft is rotatably connected to the shaft hole at the corresponding position through the bearing. Threaded portions and sleeve portions are also provided on both ends of the connecting shaft located outside the gear. A clamping nut is threadedly connected to the threaded portion, and a pulley is rotatably connected to the sleeve portion.

[0010] Furthermore, a plurality of the chain links form a sliding chain mechanism, and adjacent chain links are connected by the chain plate mechanism and the chain link mechanism.

[0011] Furthermore, the connection points between the arc-shaped curved track, the horizontal long track, and the vertical short track are all fixedly installed by a set of connecting plates. Each of the arc-shaped curved track, the horizontal long track, and the vertical short track is provided with a set of U-shaped support grooves. The horizontal long track and the vertical short track have the same structure. The two sides of the chain link are slidably connected between the set of U-shaped support grooves by two pulleys. A pressure plate is also fixedly connected inside the arc-shaped curved track at the top of the U-shaped support groove. The ends of the pressure plates at both ends of the arc-shaped curved track are also fixedly connected to sloped sections. The tops of several chain links inside the arc-shaped curved track are in contact with the bottom surface of the pressure plate through ball bearing heads.

[0012] Furthermore, a set of bearing seats and a motor base plate are fixedly installed at one end of the horizontal long track. A winch is rotatably connected between the set of bearing seats via a main shaft. A stepper motor is fixedly installed on the motor base plate. The drive shaft of the stepper motor passes through one side of the motor base plate, and the end of the drive shaft of the stepper motor is connected to one end of the main shaft via a coupling. A steel cable is wound on the winch, and one end of the steel cable is connected to the chain link plate shaft hole on one end of the slip chain mechanism.

[0013] Furthermore, the other end of the sliding chain mechanism extends to the bottom of the vertical short track, and a counterweight plate is fixedly installed on the chain link plate shaft hole on the other end of the sliding chain mechanism by bolts. A negative pressure suction cup mechanism is fixedly installed at the bottom of the counterweight plate. A corrugated protective tube is sleeved on the outside of the sliding chain mechanism located at the bottom of the vertical short track, and the top and bottom of the corrugated protective tube are fixedly installed at corresponding positions on the bottom of the vertical short track and the counterweight plate by bolts.

[0014] 3. Beneficial Effects

[0015] Compared with the prior art, the advantages of this invention are:

[0016] (1) In this scheme, after the sliding chain mechanism composed of several chain links is installed inside the arc-shaped turning track, the horizontal long track and the vertical short track, the sliding chain mechanism can smoothly move back and forth inside the arc-shaped turning track, the horizontal long track and the vertical short track. When the sliding chain mechanism moves forward, the counterweight seat plate and the negative pressure suction cup mechanism can be lowered to facilitate the picking up or putting down of materials at a low position. When the sliding chain mechanism moves backward, the counterweight seat plate and the negative pressure suction cup mechanism can be raised to facilitate the picking up or putting down of materials at a high position, thus fulfilling the vertical material conveying and transfer requirements. At the same time, when the sliding chain mechanism moves backward, several chain links of the sliding chain mechanism will be guided to the horizontal long track, which will not occupy the vertical space, thus meeting the installation and use requirements of the conveying device when the vertical height inside the workshop is insufficient.

[0017] (2) In this solution, after the sliding chain mechanism composed of several chain links is installed inside the arc-shaped turning track, the horizontal long track and the vertical short track, the sliding chain mechanism can smoothly move back and forth inside the arc-shaped turning track, the horizontal long track and the vertical short track. When the sliding chain mechanism moves forward, it can lower the counterweight seat plate and the negative pressure suction cup mechanism to facilitate picking up or putting down materials at a low position. When the sliding chain mechanism moves backward, it can lift the counterweight seat plate and the negative pressure suction cup mechanism to facilitate picking up or putting down materials at a high position, thus fulfilling the vertical material conveying and transfer requirements. At the same time, when the sliding chain mechanism moves backward, several chain links of the sliding chain mechanism will be guided into the horizontal long track and will not encroach on the vertical space upward. This fundamentally avoids interference between the vertical moving parts and the workshop roof and top pipelines, perfectly adapting to the installation and use scenario where the vertical height of the workshop is insufficient.

[0018] (3) This scheme achieves automatic locking and adaptive unlocking of the sliding chain mechanism when going straight and turning by linking the chain link mechanism and the chain plate mechanism. In the horizontal long track and the vertical short track, the support spring pushes the spline push rod so that the H-type limit part is firmly engaged with the gear, locking the chain link rotation angle and ensuring the rigidity and stability of the straight conveying section. When entering the arc-shaped turning track, the pressure plate squeezes the ball head to push the spline push rod down, releasing the locking. The chain link can rotate freely to adapt to the curve arc, avoiding the problem of the conveyor chain getting stuck and difficult to turn, and improving the smoothness of operation.

[0019] (4) In this scheme, a corrugated pipe protective tube is installed at the bottom of the vertical short track, which can form a full-coverage protection for the exposed slip chain mechanism section. The counterweight design of the counterweight seat plate can balance the overall force of the slip chain, prevent the steel cable from loosening and knotting, and improve the reliability and service life of the device.

[0020] (5) In this scheme, the device adopts a modular chain link and splicing track design. Each component can be assembled, disassembled and replaced independently, reducing the difficulty of installation and maintenance. The overall structure is compact and the layout is flexible, reducing the reservation of longitudinal installation space and improving versatility and scenario adaptability.

[0042] The technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] Please see Figures 1-14 A suspended intelligent truss conveying device includes an arc-shaped curved track 16, a horizontal long track 17, a vertical short track 18, and several identical chain links 2. Each chain link 2 includes a chain link mechanism 3 and a chain plate mechanism 9. The chain link mechanism 3 includes an H-shaped chain link 4. Both ends of the H-shaped chain link 4 are provided with connecting grooves 401 and a set of shaft holes 402. A splined shaft hole 403 is provided on the H-shaped chain link 4 located between the two connecting grooves 401. A splined shaft hole 403 is slidably connected inside the splined shaft hole 403. A key push rod 5 is provided, and a ball head 6 is fixedly installed on the top of the spline push rod 5. A support spring 7 is also sleeved on the spline push rod 5 located between the spline shaft hole 403 and the ball head 6. The bottom of the spline push rod 5 extends through to the bottom of the H-type chain link 4, and an H-type limiting member 8 is fixedly installed at the bottom end of the spline push rod 5 by bolts. Four locking ends 801 are symmetrically arranged on the H-type limiting member 8. An inlay opening 404 is also opened on the H-type chain link 4 corresponding to the locking end 801.

[0045] The assembly principle of the chain link mechanism of this type of suspended intelligent truss conveyor is as follows:

[0046] First, the support spring 7 of the chain link mechanism 3 is fitted onto the spline push rod 5. Then, the spline push rod 5 is inserted into the spline shaft hole 403, and the bottom is bolted with an H-shaped limiting piece 8. This allows the spline push rod 5 to extend and retract inside the spline shaft hole 403 when the ball head 6 at the top of the spline push rod 5 is pressed back and forth. This causes the H-shaped limiting piece 8 to rise and fall at the bottom of the H-shaped chain link 4, and allows the four snap-fit ​​ends 801 of the H-shaped limiting piece 8 to engage and disengage in the corresponding inlay openings 404. This facilitates the engagement and limiting of the gear 12 at the corresponding position later. The support spring 7 provides reverse support and springback reset after the spline push rod 5 is pressed.

[0047] Example 2:

[0048] In view of the above embodiment 1, further description is provided, see reference. Figures 1-14The chain plate mechanism 9 includes a chain link plate 10. One end of the chain link plate 10 is embedded in a connecting groove 401. A connecting shaft 11 is fixedly sleeved inside the chain link plate 10. Both ends of the connecting shaft 11 extend to the outside of the H-shaped chain link 4. A set of gears 12 is fixedly sleeved on the connecting shaft 11 located outside the H-shaped chain link 4. The tooth opening at the corresponding position of the inlay opening 404 and the tooth opening at the bottom of the gear 12 are engaged by a snap-fit ​​end 801. Limiting protrusions 1101 are fixedly connected at equal intervals on the outer wall of the connecting shaft 11 located at the connection between the gear 12 and the chain link plate 10. A bearing 13 is sleeved on the connecting shaft 11 located between the gear 12 and the chain link plate 10. The connecting shaft 11 is rotatably connected to the shaft hole 402 at the corresponding position through the bearing 13. Threaded parts and sleeved parts are also provided on both ends of the connecting shaft 11 located outside the gear 12. A clamping nut 14 is threadedly connected to the threaded part, and a pulley 15 is rotatably connected to the sleeved part.

[0049] Several chain links 2 form a sliding chain mechanism 1, and adjacent chain links 2 are connected by a chain plate mechanism 9 and a chain link mechanism 3.

[0050] The assembly principle of the chain plate mechanism and the connection principle of the sliding chain mechanism of this type of suspended intelligent truss conveyor are as follows:

[0051] First, one end of the link plate 10 is embedded in one of the connecting grooves 401 of the H-shaped link 4, and a connecting shaft 11 is inserted between the two shaft holes 402 at the connection point and the shaft hole portion of the link plate 10. The connection between the connecting shaft 11 and the two shaft holes 402 is rotatably connected by a bearing 13.

[0052] Then, two gears 12 are fitted onto the connecting shaft 11 on the outside of the H-type chain link 4. At this time, the connection between the two gears 12 and the connecting shaft 11, and the connection between the shaft hole of the chain link plate 10 and the connecting shaft 11 are all limited by the limiting protrusion 1101 on the connecting shaft 11, so that a stable connection structure is formed between the two gears 12, the chain link plate 10 and the connecting shaft 11, preventing the connecting shaft 11 from rotating relative to the two gears 12 or the chain link plate 10.

[0053] Then, install the clamping nuts 14 on the threaded parts on the outside of the two gears 12 to prevent the gears 12 from loosening. Finally, rotate the two pulleys 15 onto the sleeves at both ends of the connecting shaft 11. At this point, the assembly of the chain plate mechanism 9 onto the chain link mechanism 3 is completed, and a complete chain link 2 is formed.

[0054] When it is necessary to assemble the slip chain mechanism 1, simply assemble the first link 2 first, and then assemble the chain plate mechanism 9 of the second link 2 onto a set of shaft holes 402 on the other side of the first link 2. As described above, this completes the assembly of two adjacent links 2. Continue in this manner until the length of the assembled, end-to-end connected links 2 meets the required length of the slip chain mechanism 1. At this point, the assembly of the slip chain mechanism 1 is complete.

[0055] Example 3:

[0056] In view of the above embodiments 1 and 2, further description is provided, please refer to... Figures 1-14 The connection between the curved track 16, the horizontal long track 17, and the vertical short track 18 is fixedly installed by a set of connecting plates. The curved track 16, the horizontal long track 17, and the vertical short track 18 are all provided with a set of U-shaped support grooves 1601. The horizontal long track 17 and the vertical short track 18 have the same structure. The two sides of the chain link 2 are slidably connected between the set of U-shaped support grooves 1601 by two pulleys 15. The curved track 16 located at the top of the U-shaped support groove 1601 is also fixedly connected to a pressure plate 1602. The ends of the pressure plate 1602 located at both ends of the curved track 16 are also fixedly connected to a ramp 1603. The tops of several chain links 2 located inside the curved track 16 are in contact with the bottom surface of the pressure plate 1602 through ball bearing heads 6.

[0057] A set of bearing seats 19 and a motor base plate 20 are fixedly installed at one end of a horizontal long track 17. A winch 21 is rotatably connected between the set of bearing seats 19 via a main shaft. A stepper motor 22 is fixedly installed on the motor base plate 20. The drive shaft of the stepper motor 22 passes through to one side of the motor base plate 20, and the end of the drive shaft of the stepper motor 22 is connected to one end of the main shaft via a coupling. A steel cable 23 is wound on the winch 21. One end of the steel cable 23 is connected to the shaft hole of the chain link plate 10 on one end of the slip chain mechanism 1.

[0058] The other end of the sliding chain mechanism 1 extends to the bottom of the vertical short track 18, and a counterweight plate 24 is fixedly installed on the shaft hole of the chain link plate 10 on the other end of the sliding chain mechanism 1 by bolts. A negative pressure suction cup mechanism 25 is fixedly installed at the bottom of the counterweight plate 24. A corrugated pipe protective tube 26 is sleeved on the outside of the sliding chain mechanism 1 located at the bottom of the vertical short track 18, and the top and bottom of the corrugated pipe protective tube 26 are fixedly installed at corresponding positions on the bottom of the vertical short track 18 and the counterweight plate 24 by bolts.

[0059] Assembly and working principle of the slip chain mechanism of this type of suspended intelligent truss conveyor:

[0060] First, the curved track 16, the horizontal long track 17, and the vertical short track 18 are connected and fixedly installed through a connecting plate. Then, one end of the sliding chain mechanism 1 is inserted into the horizontal long track 17 through one end of the horizontal long track 17, and gradually guided to extend to the bottom of the vertical short track 18, so that the sliding chain mechanism 1 can stay between the curved track 16, the horizontal long track 17, and the vertical short track 18. At this time, several chain links 2 located between the curved track 16, the horizontal long track 17, and the vertical short track 18 are slidably connected to the U-shaped brackets 1601 inside the curved track 16, the horizontal long track 17, and the vertical short track 18 through the pulleys 15 on both sides, ensuring that the sliding chain mechanism 1 can move back and forth smoothly between the curved track 16, the horizontal long track 17, and the vertical short track 18.

[0061] During the movement, since the top of the horizontal long track 17 and one side of the vertical short track 18 are both open, the top of the ball head 6 of several chain links 2 inside the horizontal long track 17 and the vertical short track 18 will not be subjected to compressive force. Therefore, the support spring 7 can firmly push the spline push rod 5 upward and make the snap-fit ​​end 801 of the H-type limit piece 8 firmly snap into the corresponding tooth of the inlaid opening 404 and the bottom of the gear 12. This ensures that the gear 12 of the chain plate mechanism 9 will not deflect relative to the H-type chain link 4 of the chain link mechanism 3, thereby achieving the effect of fixing and locking the connection between the H-type chain link 4 and the chain plate 10. This ensures that the sliding chain mechanism 1 section inside the horizontal long track 17, inside the vertical short track 18, and at the bottom of the vertical short track 18 can move in a directional and non-bending form.

[0062] Because the curved turning track 16 has a pressure plate 1602 and a ramp 1603 inside, when each link 2 of the slip chain mechanism 1 passes through its interior, the ball head 6 at the top of the link 2 will cross the corresponding ramp 1603 and be pressed against the bottom of the pressure plate 1602. At this time, the spline push rod 5 and the H-shaped limiter 8 will be pushed downward, causing the locking end 801 to disengage from the inlay opening 404 and the tooth of the gear 12, and releasing the lock at the connection between the H-shaped link 4 and the link plate 10. Therefore, the connection between the H-shaped link 4 and the link plate 10 inside the curved turning track 16 can rotate freely, achieving the effect of unlocking and changing direction when the slip chain mechanism 1 passes through the interior of the curved turning track 16, so as to adapt to the track structure of the curved turning track 16 and move smoothly.

[0063] The stepper motor 22 can drive the winch 21 to rotate precisely, and the winch 21 can precisely wind up or release the wound steel cable 23, achieving the effect of pulling and controlling the movement of the slide chain mechanism 1 from one end. The other end of the slide chain mechanism 1 is equipped with a negative pressure suction cup mechanism 25 through the counterweight plate 24 (the specific structure and working principle of the negative pressure suction cup mechanism are known and publicly available technologies, so they will not be described in detail here). The counterweight plate 24 is installed at the other end of the slide chain mechanism 1 to provide counterweight to the other end of the slide chain mechanism 1, preventing the slide chain mechanism 1 from having insufficient driving force to move backward when the winch 21 releases the steel cable 23, causing the steel cable 23 to become knotted or the slide chain mechanism 1 to be unable to drive the negative pressure suction cup mechanism 25 to move downward, thus ensuring the smooth reciprocating movement of the slide chain mechanism 1 between the curved track 16, the horizontal long track 17, and the vertical short track 18.

[0064] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
