Description

Technical Field

[0001] This utility model relates to the field of cross bar conveyor technology, and specifically to a bidirectional articulated chain for a cross bar conveyor. Background Technology

[0002] In the field of industrial production and logistics transportation, the bidirectional articulated chain of the cross bar conveyor, with its unique structural design, can achieve bidirectional rotation in both horizontal and vertical directions, flexibly adapting to complex spatial conveying paths, and is widely used in automated production lines in industries such as automobile manufacturing, logistics warehousing, and food processing.

[0003] According to the public announcement (CN204610694U), a cross-shaft type universal chain is disclosed. This technology discloses "a system comprising at least two relatively rotatable unit chain links and a cross-shaft connecting piece for connecting adjacent unit chain links. Each unit chain link includes two sets of traveling devices and a cross-shaft connecting piece connecting the two sets of traveling devices. Each set of traveling devices includes a cross-shaft, traveling wheels installed at both ends of the horizontal axis of the cross-shaft, and drive wheels installed at both ends of the vertical axis of the cross-shaft. The horizontal axes of the two sets of cross-shafts in each unit chain link are connected by the cross-shaft connecting piece. The vertical axes of the two sets of cross-shafts in the unit chain link are respectively connected to the vertical axes of the cross-shafts in adjacent chain links by means of the cross-shaft connecting piece bushings. This technology has the advantages of transmitting torque in two directions through the cross-shaft, realizing the transmission of power in three-dimensional space, and also enabling load-bearing transport, thus expanding the scope of application. Compared with the existing bearing type universal chain, it has a simpler structure, is easier to process, reduces costs, and has a more reasonable force distribution."

[0004] In the aforementioned comparative documents, although bidirectional transmission of the chain is achieved through the cross shaft, the cross shaft is constantly rotating and bearing weight during use, which easily leads to friction and wear. If lubrication is not timely or sufficient, it will cause a sudden increase in friction at the connection, which not only aggravates component wear and shortens the chain's service life, but may also cause problems such as running jams, increased noise, and increased power consumption. In severe cases, it may even cause the chain to jam or derail, affecting the stability and production efficiency of the entire conveying system.

[0005] To address the aforementioned issues, this application proposes a bidirectional articulated chain for a crossbar conveyor. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a bidirectional articulated chain for a cross-shaped conveyor.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A bidirectional articulated chain for a crossbar conveyor includes a first connecting plate and a second connecting plate. A first rotating rod is provided on the first connecting plate, and a drive wheel is rotatably connected to the side wall of the first connecting plate. A second rotating rod is rotatably connected to the second connecting plate. The inner wall of the second rotating rod is in contact with the outer wall of the first rotating rod. A liquid storage cavity is provided on the second rotating rod, and the liquid storage cavity of the second rotating rod is connected to an injection hole provided on the second connecting plate. A lower liquid groove is provided on the outer wall of the first rotating rod, and the lower liquid groove of the first rotating rod is connected to an oil outlet hole provided on the second rotating rod. A delivery groove is provided on the first rotating rod, and the delivery groove of the first rotating rod is connected to the lower liquid groove of the first rotating rod. An inclined groove is provided on the first rotating rod, and the delivery groove of the first rotating rod is connected to the inclined groove of the first rotating rod.

[0008] A spring is fixedly connected to the first rotating rod, and a top block is connected to the top of the spring. The outer wall of the top block fits against the oil outlet hole of the second rotating rod. By setting the spring and the top block, the oil outlet hole of the second rotating rod is sealed, thereby preventing lubricating oil from flowing out through the oil outlet hole when the chain moves in parallel, and thus preventing the lubricating oil from dripping too quickly and affecting the use of the chain.

[0009] A threaded block is rotatably connected to the first connecting plate, and a threaded groove is opened on the outer wall of the first rotating rod. The inner wall of the threaded block is threadedly connected to the threaded groove opened on the outer wall of the first rotating rod. A blocking plate is provided on the outer wall of the first rotating rod, and one side of the blocking plate is in contact with one side of the threaded block. By setting the threaded groove, the threaded block and the blocking plate, the chain component can be disassembled.

[0010] A magnetic block is fixedly connected to the side of the threaded block near the blocking plate. The outer wall of the magnetic block is in contact with the side of the blocking plate near the threaded block. By setting the magnetic block, the blocking plate is fixed, preventing the blocking plate from becoming loose due to vibration during chain use, thereby avoiding affecting the stability of the chain.

[0011] A support rod is fixedly connected to the outer wall of the second rotating rod. One end of the support rod is in contact with the side of the blocking plate away from the threaded block. By setting the support rod, the second connecting plate and the second rotating rod are stabilized, and the second rotating rod is prevented from swaying left and right after it is connected to the first rotating rod, thereby avoiding affecting the stable use of the chain.

[0012] The second connecting plate is provided with a connecting rod, and a limit wheel is fixedly connected to the outer wall of the connecting rod. By setting the connecting rod and the limit wheel, the overall operation of the chain is stabilized, and the chain is prevented from shaking during operation, thereby preventing damage to the transport of goods.

[0013] A bearing is fixedly connected to the second connecting plate. The inner shaft of the bearing is fixedly connected to the outer wall of the limiting wheel. By setting the bearing, the friction at the connection between the connecting rod and the second connecting plate is reduced, thereby avoiding excessive friction when the connecting rod rotates, and thus preventing the connecting rod from jamming when rotating.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a liquid storage chamber, a lower liquid tank, a liquid delivery tank, and an inclined trough, lubrication is achieved at the connection points between the first connecting plate and the drive wheel, and between the first rotating rod and the second rotating rod. At the same time, the lubricating fluid flows out intermittently, thereby reducing the waste of lubricating fluid. In addition, the lubricating fluid at the connection points between the first connecting plate and the drive wheel, and between the first rotating rod and the second rotating rod, can continuously reduce the friction at the connection points, thereby reducing wear and extending the service life of the drive wheel.

[0016] By setting threaded grooves, threaded blocks, and blocking plates, the chain components can be disassembled. When the chain is damaged, the chain components can be disassembled and replaced individually without replacing the entire chain, which greatly reduces the cost of spare parts. At the same time, during the disassembly process, undamaged components can remain in place, avoiding secondary damage or readjustment caused by overall disassembly and reassembly, and further shortening the maintenance cycle.

[0033] Working principle:

[0034] The bidirectional articulated chain of this crossbar conveyor has a turning mechanism. When the chain turns, the first rotating rod 3 rotates, causing the top block 11 to retract inward. At this time, lubricating oil flows out of the oil outlet on the second rotating rod 5. The lubricating oil flows through the oil outlet, the lower liquid tank 7, and the liquid delivery tank 8 into the interior of the inclined chute 9, and then flows from the interior of the inclined chute 9 into the connection between the drive wheel 4 and the first connecting plate 1. This reduces the friction at the connection between the first connecting plate 1 and the drive wheel 4. If any chain component is damaged during long-term use, the first connecting plate 1 and the first rotating rod 3 can be separated by the blocking plate 14 and the magnetic block 15, allowing the component to be replaced and preventing any impact on the chain's operation.
