Description

Technical Field

[0001] This utility model relates to the field of plate chain technology, specifically a lubricated guide plate chain. Background Technology

[0002] In modern industrial equipment systems, plate chains, with their high load-bearing capacity and strong toughness, have become the core transmission component of heavy machinery in metallurgy, mining, and logistics transportation. To address the problems of chain misalignment and jamming under complex working conditions, early lubricated guide plate chains were developed by adding a guide structure to assist in positioning during chain operation. This significantly reduced abnormal friction between the chain and the guide rails and sprockets, effectively extending the service life of the chain body.

[0003] However, as equipment operating time accumulates and operating conditions become more complex, the limitations of traditional guide structures gradually become apparent. Because guide components are often integrated with chain links, once deep damage occurs to the guide surface, maintenance personnel cannot replace or repair them individually; they must disassemble the entire chain for replacement. This not only significantly increases downtime for maintenance but also incurs high spare parts and labor costs due to frequent chain replacements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lubricated guide plate chain, which solves the problem mentioned in the background technology that, due to the integrated design of the guide components with the chain links, once the guide surface is deeply damaged, maintenance personnel cannot replace or repair them individually, and can only disassemble the entire chain link for replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lubricated guide plate chain, comprising an outer chain plate and an inner chain plate, wherein a connecting chain plate is connected to the middle of the inner chain plate via a pin, and an installation tube is fixedly disposed in the middle of the connecting chain plate, wherein spiral grooves are provided at both ends of the installation tube, and a guide member is inserted into the outer chain plate, wherein the guide member includes a guide rod, one end of the guide rod is provided with an installation rod, the installation rod is spirally connected to the spiral groove, and an annular guide groove is provided on the other end of the guide rod, wherein a slot is provided on the end of the guide rod near the guide groove.

[0006] Preferably, a limiting groove is provided on the mounting rod.

[0007] Preferably, both ends of the mounting tube are provided with through holes, and the diameter of the through holes is the same as the width of the limiting groove.

[0008] Preferably, the top of the connecting chain plate is provided with an arc-shaped groove, and the top of the arc-shaped groove is provided with a placement groove.

[0009] Preferably, a pull plate is placed in the placement groove, the width of the pull plate is the same as the width of the placement groove, and a limit rod is fixedly provided at both ends of the pull plate. A spring is provided around the periphery of the limit rod, and the two ends of the spring are respectively connected to the pull plate and the mounting tube.

[0010] Preferably, the limiting rod is adapted to the through hole, and the limiting rod passes through the through hole and corresponds to the limiting groove.

[0011] This utility model provides a lubricated guide plate chain. It has the following beneficial effects:

[0012] (1) The guide component and the connecting chain plate of this utility model are assembled by spiral connection, rather than the traditional integrated casting or welding. When the annular guide groove of the guide rod needs maintenance due to wear, the guide component can be removed from the outer chain plate by rotating the guide component with a tool. The guide component can be replaced separately without disassembling the entire chain link or chain, thus achieving quick maintenance and shortening the repair time.

[0013] (2) In this utility model, the limiting rod passes through the through hole and is connected to the limiting groove. After the limiting rod is inserted into the limiting groove, it can prevent the mounting rod from rotating around the spiral groove, avoid the guide part from loosening on its own due to chain vibration and impact load, lock the extension length of the guide rod, and ensure stable guiding accuracy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example 1:

[0024] Please see Figures 1-5 This utility model provides a lubricated guide plate chain, including an outer chain plate 1 and an inner chain plate 2. The middle of the inner chain plate 2 is connected to a connecting chain plate 3 by a pin. An installation tube 31 is fixedly provided in the middle of the connecting chain plate 3. Both ends of the installation tube 31 are provided with spiral grooves 311. A guide member 4 is inserted into the outer chain plate 1. The guide member 4 includes a guide rod 41. One end of the guide rod 41 is provided with an installation rod 42. The installation rod 42 is spirally connected to the spiral groove 311. The other end of the guide rod 41 is provided with an annular guide groove 44. A slot 45 is opened on the end of the guide rod 41 near the guide groove 44.

[0025] Specifically, the guide groove 44 cooperates with the external fixed track or flange to form a mechanical constraint, forcibly restricting the lateral deviation or sway of the chain during operation, avoiding the risk of derailment due to uneven load or inertia. The guide component 4 and the outer chain plate 1 adopt a split structure, and the guide rod 41 is spirally connected to the spiral groove 311 through the mounting rod 42. Therefore, when the guide groove 44 is worn, it can be replaced simply by rotating and pulling out the guide component 4, without removing other parts of the chain.

[0026] The helical engagement between the mounting rod 42 and the spiral groove 311 provides reliable connection strength, while allowing the guide 4 to be disassembled by simple rotation. It is easier to maintain than traditional welded or one-piece structures, and maintenance personnel can quickly complete the replacement using standard tools, greatly reducing downtime.

[0027] Furthermore, to ensure the stability of guide rod 41, please refer to... Figures 1-5 A limiting groove 43 is provided on the mounting rod 42;

[0028] Both ends of the mounting tube 31 are provided with through holes 312, and the diameter of the through holes 312 is the same as the width of the limiting groove 43.

[0029] An arc-shaped groove 33 is provided on the top of the connecting chain plate 3, and a placement groove 34 is provided on the top of the arc-shaped groove 33;

[0030] A pull plate 32 is placed in the placement groove 34. The width of the pull plate 32 is the same as the width of the placement groove 34. Limit rods 321 are fixedly installed at both ends of the pull plate 32. Springs 322 are installed around the limit rods 321. The two ends of the springs 322 are respectively connected to the pull plate 32 and the mounting tube 31.

[0031] The limiting rod 321 is adapted to the through hole 312, and the limiting rod 321 passes through the through hole 312 and corresponds to the limiting groove 43.

[0032] Specifically, after the through holes 312 at both ends of the mounting tube 31 are aligned with the limiting grooves 43 of the mounting rod 42, the limiting rod 321 passes through the through holes 312 and is inserted into the limiting grooves 43 to form a rod-groove locking structure. At this time, the mounting rod 42 of the guide rod 41 is laterally locked by the limiting rod 321 and cannot rotate axially around the spiral groove 311, ensuring that the circumferential position of the guide rod 41 is fixed during chain operation, preventing the guide member 4 from loosening on its own due to chain vibration and impact load, locking the extension length of the guide rod 41, and ensuring stable guiding accuracy.

[0033] In its natural state, the spring 322 is in normal condition, keeping the limiting rod 321 pressed tightly in the limiting groove 43, which ensures the stability of the limiting rod 321.

[0034] When the guide component 4 needs to be replaced, a tool is inserted into the arc-shaped groove 33 to lift the pull plate 32 from the placement groove 34, causing the limiting rod 321 to move upward and disengage from the limiting groove 43. At the same time, the spring 322 is stretched, making it easier to rotate the guide rod 41 to remove it. The new guide component 4 is then rotated and installed in the spiral groove 311, controlling the limiting groove 43 to correspond with the through hole 312. The tool is then released, allowing the spring 322 to return to its original state. Under the action of the spring 322, the pull plate 32 drives the limiting rod 321 to move downward, passing through the through hole 312 and entering the limiting groove 43, thus restricting the new guide rod 41 and completing the installation of the new guide component 4.

[0035] Working principle: The inner chain plate 2 is assembled with the connecting chain plate 3 through the pin to form a basic chain unit, and the outer chain plate 1 is sleeved on the outside of the inner chain plate 2.

[0036] Insert a tool into the arc-shaped groove 33 at the top of the connecting chain plate 3, pull the pull plate 32 upwards, stretch the spring 322, and make the limiting rod 321 disengage from the limiting groove 43. Align the mounting rod 42 of the guide rod 41 with the spiral groove 311 of the mounting tube 31. Use a tool to rotate the guide rod 41 clockwise through the slot 45, so that the mounting rod 42 is screwed into the spiral groove 311 until the annular guide groove 44 of the guide rod 41 is initially aligned with the external fixed track or flange. At this time, the through hole 312 of the mounting tube 31 is automatically aligned with the limiting groove 43 of the mounting rod 42. Release the pull plate 32, so that the pull plate 32, under the natural elastic force of the spring 322, drives the limiting rod 321 to move downwards, pass through the through hole 312 and insert into the limiting groove 43, forming a rod groove lock, preventing the guide rod 41 from rotating circumferentially, and realizing the stability of the guide member 4.

[0037] When the chain is running, the annular guide groove 44 of the guide rod 41 engages with the flange or groove of the outer track to form a mechanical constraint, which forcibly restricts the lateral deviation of the chain.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
