Description

Technical Field

[0001] This utility model relates to the field of chain technology, specifically to an industrial lifting chain with side baffles. Background Technology

[0002] Traditional industrial lifting chains connect to a cargo carrier via an outer connecting plate, placing the cargo on the carrier for vertical transport. However, traditional chains lack lateral protection, making it easy for cargo to sway and fall off during lifting. Furthermore, the fixed position of the connecting plate makes adjustment difficult, affecting the adaptability of the carrier installation. During transport, the chain also causes cargo to sway from side to side, impacting transport safety and stability. The fixed baffle structure used in existing technologies cannot adapt to the transport needs of items of different sizes, and replacement after wear is difficult.

[0003] Existing guard structures are mostly integral, which are inconvenient to disassemble and require complete replacement after wear, resulting in high costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an industrial lifting chain with side baffles, which solves the problem of the protective mechanism at the outer end of the chain. The baffles provide stability for lifting items, and the adjustment mechanism allows for adjustment of the position of the connecting plate, facilitating the installation of the lifting carrier.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial lifting chain with side baffles, comprising chain plates, sprockets, and pins. A protective mechanism is provided on the outer side of the chain plates. The protective mechanism includes alternating and staggered protective plates. The protective plates are sleeved on the outer end of the pins. A first fixing ring, a second fixing ring, and a third fixing ring are sleeved on the pins. The protective plates, the first fixing ring, the second fixing ring, and the third fixing ring are alternately stacked and fixed. A pin cap is provided at the end of the pins.

[0006] Furthermore: the lower end of the chain plate is provided with an adjustment mechanism, which includes a fixed plate, a slide, a toothed groove, a rack and a screw. The fixed plate is fixed to the lower end of the chain plate. The upper end of the fixed plate is provided with a toothed groove and a strip-shaped through hole. The slide is provided with a sliding groove. A limit plate is slidably arranged in the sliding groove. The lower end of the limit plate is fixed with a rack. The rack meshes with the toothed groove to realize the left and right position adjustment of the connecting plate.

[0007] Furthermore: the first fixing ring, the second fixing ring, and the third fixing ring create a gap between the overlapping guard plates, and the guard plates are detachable and replaceable. The first fixing ring is fixedly connected to the pin, and the second fixing ring and the third fixing ring are slidably mounted on the pin.

[0008] Furthermore: a positioning pin is provided at the end of the pin away from the guard plate, and the positioning pin is bent.

[0009] Furthermore, the pin cover and the pin shaft are fixed by friction.

[0010] Furthermore, the protective plate is arranged in an inverted trapezoidal shape, and multiple trapezoidal protective plates are stacked to improve the sealing of the enclosure.

[0011] Furthermore: a nut is fixed to the upper end of the slide block, and the screw passes through the fixing plate, the limiting plate and the slide block to the nut. The screw is threadedly connected to the limiting plate and also threadedly connected to the nut.

[0012] This invention provides an industrial lifting chain with side baffles. Compared with the prior art, it has the following advantages:

[0013] This industrial lifting chain with side baffles features a detachable protective mechanism formed by alternating staggered guard plates, effectively preventing items from swaying left and right. The guard plates can be replaced individually after wear, reducing costs. The adjustment mechanism allows for flexible adjustment of the connecting plate position through the matching of rack and pinion, improving the adaptability of carrier installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an industrial lifting chain with side baffles; the lifting chain mainly consists of chain plates 1, sprockets 2 and pins 3, wherein the chain plates 1 overlap and match the sprockets 2, the sprockets 2 are located between the two chain plates 1, and the pins 3 pass through the interior of the chain plates 1 and the sprockets 2 and are rotatably configured, thus forming a complete closure to obtain the chain. The lifting chain has a connecting plate 14 on the outside of the chain plates 1, and the carrier of the item to be lifted is fixed on the connecting plate 14. The overall rotation of the lifting chain drives the connecting plate 14 to rise, thereby driving the item to rise.

[0022] This design features a protective mechanism on the outer side of the chain plate 1. The protective mechanism mainly consists of a guard plate 7, which is fitted onto the outer end of the pin 3. The guard plates 7 are alternately staggered and slidably arranged. In this way, the guard plates 7 can prevent the item from swaying left and right when it is lifted during the overall movement. The guard plates 7 can be disassembled and replaced according to the actual needs of the item, which improves the safety and stability of the overall lifting of the chain.

[0023] The protective mechanism also includes a first fixing ring 6, which is fixed to one end of the pin 3 near the guard plate 7. The guard plate 7 is then fitted onto the pin 3 and slides against the first fixing ring 6. Next, a second fixing ring 8 is fitted on the outside of the guard plate 7, and alternating guard plates 7 are fitted on the outside of the second fixing ring 8, forming a superimposed and closed structure between the guard plates 7. Then, a third fixing ring 9 is fitted on the outside of the guard plate 7. Through the alternating superposition of the first fixing ring 6, the second fixing ring 8, and the third fixing ring 9 with the guard plate 7, gaps are formed between the guard plates 7, improving the alternating stability between the guard plates 7 and preventing wear from the superimposed guard plates 7. Finally, a pin cover 5 is fitted and fixed on the outer end of the pin 3, and the pin cover 5 closes the end of the pin 3. The pin cover 5 is fixed to the pin 3 by friction.

[0024] An adjustment mechanism is fixed at the lower end of the chain plate 1. The adjustment mechanism can adjust the left and right position of the connecting plate 14 to provide a better installation position for the carrier of the lifting item. The adjustment mechanism includes a fixed plate 10. The upper end of the fixed plate 10 is provided with a toothed groove 12, and symmetrical strip-shaped through holes 11 are provided on the fixed plate 10. A slide block 13 is fitted on the fixed plate 10. The connecting plate 14 is fixedly connected to the upper end of the slide block 13. A slide groove 15 is provided in the slide block 13, and a limit plate 16 is located in the slide groove 15 to restrict the vertical sliding. A rack 17 is fixed at the lower end of the limiting plate 16. The rack 17 is matched and corresponding to the tooth groove 12. A screw is passed from the lower end to the upper end of the fixing plate 10. The screw passes through the fixing plate 10 and the limiting plate 16 and is threadedly connected to the limiting plate 16. A nut 18 is fixed at the upper end of the slide block 13. The screw passes through the upper end of the slide block 13 and is threadedly connected to the nut 18. As the screw rotates continuously, it drives the limiting plate 16 to move closer to the fixing plate 10, bringing the rack 17 closer to the tooth groove 12 for matching and thus fixing the position of the connecting plate 14.

[0025] A positioning pin 4 is provided at the end of the pin 3 away from the guard plate 7. The positioning pin 4 is bent to facilitate disassembly and replacement, thereby improving the convenience of use.
