Description

Technical Field

[0001] This application relates to the field of overhead conveyor equipment technology, and in particular to a safety protection device for an overhead conveyor. Background Technology

[0002] As a core piece of equipment for aerial material handling in industrial production lines, the automation and intelligence level of overhead conveyors directly impacts production efficiency and safety. With technological advancements, integrating photoelectric sensors has become a key upgrade path. By strategically deploying various photoelectric sensors at critical nodes such as workstation entrances and exits, before and after switch divergence points, process connection areas, buffer zone boundaries, and high-risk areas, it is possible to accurately trigger workstation equipment actions, dynamically plan switch paths, synchronize process speeds in real time, construct emergency stop protection barriers in safe areas, and continuously collect operational status and production data.

[0003] Existing integrated photoelectric sensing overhead conveyors can achieve non-contact real-time detection of the lifting devices through photoelectric sensors, accurately sensing their position, existence status, passage timing and speed, and feeding the signals back to the PLC control system at high speed.

[0004] In the actual process of transferring workpieces, the workpieces are usually attached to the lifting device by hooks on the lifting device for transfer. However, the workpieces will sway due to inertia during the transfer. When the swaying amplitude is large, the workpieces may fall during the transportation, causing safety accidents.

[0028] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please see Figures 1-5 This application provides a safety protection device for a catenary conveyor to prevent workpieces from falling during transport.

[0030] In this embodiment, refer to Figures 1-5The safety protection device for the overhead conveyor includes a mounting plate 1, a push block 2, and a drive component 3. The mounting plate 1 has at least two through slots 11 on one surface, each through slot 11 intersecting at the center of the mounting plate 1, and the included angles formed between the through slots 11 are equal. The push block 2 is slidably disposed in the through slot 11, with one end extending outside the through slot 11 and the other end having a sliding block 22 that extends to the center of the mounting plate 1. The drive component 3 is connected to the sliding block 22 and provides a driving force for each push block 2 to slide along the through slot 11.

[0031] Specifically, by arranging at least two through slots 11 in a cross pattern, and with push blocks 2 slidably connected to the through slots 11, at least four push blocks 2 extend from one end of the through slots 11 to provide abutment support for the workpiece during suspended transport, thereby effectively reducing the swaying phenomenon of the workpiece during suspended transport. Furthermore, by synchronously driving multiple sliding blocks 22 with the drive component 3, the push blocks 2 can slide on the through slots 11, causing the push blocks 2 to simultaneously abut against the workpiece from multiple directions, further ensuring the stability of the abutment state between the push blocks 2 and the workpiece, and also helping to improve the overall stability of the workpiece in the transfer process, ultimately reducing the probability of the workpiece falling and improving the safety of workpiece transfer.

[0032] See Figure 2 In an exemplary embodiment, the driving component 3 includes a driving disk 31 and a driving motor 32. The driving disk 31 has a plurality of arc-shaped holes evenly spaced in the radial direction, and the sliding block 22 extends into the arc-shaped holes. The output end of the driving motor 32 is connected to the driving disk 31, and the driving motor 32 is located on the side of the driving disk 31 away from the mounting plate 1.

[0033] Specifically, the arc-shaped hole of the drive disk 31 cooperates with the sliding block 22 to convert the rotational motion of the drive disk 31 into the linear sliding of the push block 2, thereby realizing the synchronous driving of multiple push blocks 2 and ensuring the consistency of the actions of each push block 2. The drive motor 32 provides stable power and is located on the side away from the mounting plate 1 to avoid interfering with the action of the push block 2. The overall structure is compact and the transmission efficiency is high, ensuring that the push block 2 has a uniform contact force with the workpiece and enhancing the support stability.

[0034] See Figure 1 and Figure 2 In an exemplary embodiment, the device further includes a fixing member 6, which includes a fixing motor 62 and a fixing hook 61. The fixing motor 62 is fixedly connected to the end of the push block 2 away from the sliding block 22. One end of the fixing hook 61 is connected to the output end of the fixing motor 62, and the fixing hook 61 is located on the side of the push block 2 away from the driving member 3.

[0035] Specifically, the fixed motor 62 provides rotational power to the fixed hook 61, and can adjust the hook angle according to the shape of the workpiece to ensure that the hook effectively hooks the workpiece; when the workpiece to be transferred cannot be firmly fixed by the push block 2, the fixed motor 62 drives the fixed hook 61 to rotate to grip the workpiece to be transferred, preventing the workpiece from shaking and falling off, adapting to workpieces of different sizes and shapes, and improving the reliability of fixing.

[0036] See Figure 2 In an exemplary embodiment, a flexible pad 21 is provided at the end of the push block 2 away from the sliding block 22.

[0037] Specifically, the flexible pad 21 can buffer the impact force between the push block 2 and the workpiece, avoiding damage to the workpiece surface caused by hard contact; at the same time, the flexible material has a certain deformation capability, which can better fit the workpiece surface, increase the contact area, improve the contact stability, prevent the workpiece from being displaced due to rigid collision during contact, and enhance the protective effect.

[0038] See Figure 1 In an exemplary embodiment, the device further includes a connector 5, which includes: a plurality of connecting posts 54 disposed on the mounting plate 1 near the drive member 3, and each connecting post 54 being located at the included angle formed by two through slots 11; one end of the protective cylinder 52 is connected to each connecting post 54, and the other end is provided with a top plate 51, and the drive disk 31 and the drive motor 32 are located inside the protective cylinder 52.

[0039] Specifically, the connecting column 54 is located at the angle of the through slot 11, which does not affect the movement of the push block 2 and can stably support the protective cylinder 52; the protective cylinder 52 isolates the drive disk 31 and drive motor 32 from the external environment, preventing dust, debris or workpiece collisions from damaging the drive component 3 and ensuring the stable operation of the drive system; the top plate 51 enhances the structural strength of the protective cylinder 52, while providing an installation base for other components and extending the service life of the device.

[0040] See Figure 1 and Figure 5 In an exemplary embodiment, the connector 5 further includes a connecting rod 53 and a roller 4, wherein two connecting rods 53 are symmetrically mounted on the surface of the top plate 51 away from the protective cylinder 52; the roller 4 is rotatably connected to the end of the connecting rod 53 away from the top plate 51.

[0041] Specifically, the symmetrically arranged connecting rods 53 ensure that the rollers 4 are balanced under force, preventing the device from tilting when moving; the rollers 4 can convert the sliding friction between the device and the track into rolling friction, reducing the moving resistance, so that the device can smoothly follow the suspension chain and the workpiece to move synchronously, ensuring that the protective device continuously acts on the workpiece and ensuring the safety of the entire transfer process.

[0042] See Figure 1 , Figure 4 and Figure 5In an exemplary embodiment, the system further includes two sets of auxiliary components 7 symmetrically arranged on both sides of the top plate 51. The auxiliary components 7 include: a winding motor 71, a winding roller 72, a steel chain 73, and an auxiliary hook 74. The winding motor 71 is embedded in the top plate 51, and the drive end of the winding motor 71 extends out of the top plate 51. One end of the winding roller 72 is connected to the drive end of the winding motor 71, and the winding motor 71 provides rotational driving force for the winding roller 72. One end of the steel chain 73 is connected to the winding roller 72, and the other end hangs freely. The auxiliary hook 74 is connected to the free-hanging end of the steel chain 73.

[0043] Specifically, the winding motor 71 precisely controls the length of the steel chain 73 to adapt to workpieces of different heights; the winding roller 72 stably winds the steel chain 73 to prevent the steel chain 73 from becoming disordered; the auxiliary hook 74 can hook additional parts of the workpiece and cooperate with the fixed hook 61 to form a multi-dimensional, multi-point fixation, which is especially suitable for large or irregular workpieces, further dispersing the force on the workpiece, preventing it from shaking and falling, and improving the versatility and protective effect of the device.

[0044] See Figure 4 In an exemplary embodiment, the take-up roller 72 includes: a rotating rod 721, a side guard plate 722, and a fixed rod 723. The rotating rod 721 is connected to the drive end of the take-up motor 71. Two side guard plates 722 are symmetrically arranged on the rotating rod 721, and the side guard plate 722 closer to the take-up motor 71 is rotatably connected to the rotating rod 721. A plurality of fixed rods 723 are evenly distributed on the side guard plate 722 near the top plate 51. One end of the fixed rod 723 is connected to the top plate 51, and the other end is connected to the side guard plate 722 near the top plate 51.

[0045] Specifically, the side guard plate 722 can prevent the steel chain 73 from shifting to both sides during winding, ensuring that the steel chain 73 is neatly wound on the rotating rod 721, and preventing the steel chain 73 from falling off or becoming tangled; the fixing rod 723 enhances the stability of the side guard plate 722 near the top plate 51, preventing it from shaking during winding, ensuring the overall structure of the winding roller 72 is stable, the steel chain 73 is wound and unwound smoothly, and improving the working reliability of the auxiliary component 7.

[0046] See Figure 4 In an exemplary embodiment, the auxiliary component 7 further includes a locking member 75, which includes: a ratchet 751, a hinge frame 754, a pawl 752, a spring 753, and an adjusting cylinder 755. The ratchet 751 is sleeved on the rotating rod 721; one end of the pawl 752 engages with the ratchet 751; the hinge frame 754 is located on the side of the pawl 752 near the ratchet 751; one end of the spring 753 is connected to the hinge frame 754, and the other end is connected to the pawl 752, providing a preload force for the ratchet 751; the adjusting cylinder 755 is located on the side of the side guard plate 722 near the top plate 51, and the pushing end of the adjusting cylinder 755 abuts against the end of the pawl 752 away from the ratchet 751.

[0047] Specifically, the preload of the spring 753 ensures that the pawl 752 stably engages with the ratchet 751, preventing the rotating rod 721 from rotating in the opposite direction and causing the steel chain 73 to loosen, thus ensuring that the hooking force of the auxiliary hook 74 on the workpiece is stable; the adjusting cylinder 755 can control the pawl 752 to disengage from the ratchet 751, making it convenient to adjust the length of the steel chain 73 to adapt to different workpieces, realizing flexible switching between locking and unlocking, and enhancing the safety and ease of operation of the auxiliary component 7.

[0048] In an exemplary embodiment, the flexible pad 21 is made of rubber or polyurethane, and the surface of the flexible pad 21 that contacts the workpiece is provided with anti-slip texture.

[0049] Specifically, rubber or polyurethane has good elasticity and wear resistance, which can buffer the impact force of the push block 2 and protect the workpiece surface from being scratched; the anti-slip texture increases the friction between the flexible pad 21 and the workpiece, preventing the workpiece from sliding relative to the push block 2 when it abuts, ensuring that the push block 2 abuts and fixes the workpiece more firmly, and further reducing the risk of the workpiece falling.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
