[0002] With the continuous development of the automation industry, linear motion is frequently required in various automation equipment applications. Currently, the main methods for achieving linear motion include cylinders, hydraulic cylinders, ball screws, crank-slider systems, gear racks, worm gears, synchronous belts, and ordinary chains. Each of these transmission methods has its own advantages and disadvantages, and none can simultaneously possess the characteristics of long-distance, bidirectional, high speed, high rigidity, high precision, good stability, large load capacity, high efficiency, low noise, and small space occupation. Therefore, how to achieve multi-directional and rapid material transfer has become a challenge. Summary of the Invention

[0003] This invention discloses a multi-directional horizontal pushing chain drive device. This device simultaneously meets the characteristics of long distance, bidirectional operation, high speed, high rigidity, high precision, good stability, large load capacity, high efficiency, low noise, and small space occupation. It can also realize multi-directional linear transmission, that is, pushing or pulling linearly to both sides along the two ends of the guide rail mechanism, or pushing or moving back and forth linearly within the range of the guide rail mechanism. It can be widely used in fields such as automated parking systems, industrial automation, logistics warehousing, engineering machinery, military equipment, and precision manufacturing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-directional horizontal push chain drive device includes a guide rail mechanism and an interlocking push chain. The interlocking push chain is a double-chain structure composed of two interlocking single chains. The double chain forms a rigid linear push chain, the head of which is used to push an item. The guide rail mechanism includes a double-chain guide rail located in the middle for the double-chain structure to travel, and single-chain guide rails connected end-to-end to the double-chain guide rail and located on both sides of the double-chain guide rail. The length of each single chain is greater than the length of the single-chain guide rail, and satisfies the following requirements: allowing the double chain to push or move the target item back and forth within the range of the double-chain guide rail; and allowing the double chain to output from the left or right end of the guide rail mechanism and push or pull the target item outside the guide rail mechanism.

[0006] Preferably, the guide rail mechanism includes a mounting plate and a guide rail frame disposed on the upper surface of the mounting plate. The middle part of the guide rail frame forms a first channel for mounting a double-chain guide rail. The guide rail frame is provided with second channels for mounting single-chain guide rails at positions on both sides of the first channel. The two ends of the first channel and the two ends of the second channels on both sides are interconnected according to the trajectory of the single chain. The bottom of the mounting plate is provided with a drive mechanism. The drive mechanism is connected to a plurality of drive sprocket sets disposed in the guide rail frame for transmission, and the single chain and the double chain are driven to move together by the plurality of drive sprocket sets.

[0007] Preferably, the single chain is a roller chain structure, and the double chain guide rail includes short wear-resistant guide rails located on the inner walls of both sides of the first channel. The short wear-resistant guide rails on both sides are in rolling friction engagement with the rollers on both sides of the double chain. The single chain guide rail includes a long wear-resistant guide rail located on the inner surface of the outer wall of the second channel and a short wear-resistant guide rail located on the outer surface of the inner wall of the second channel. The rollers of the single chain are in rolling friction engagement with the adjacent long wear-resistant guide rail and short wear-resistant guide rail. The difference between the long wear-resistant guide rail and the short wear-resistant guide rail is that the width of the cross-section of the long wear-resistant guide rail is greater than the width of the cross-section of the short wear-resistant guide rail.

[0008] Preferably, the connection between the ends of the single-chain guide rail and the double-chain guide rail is an arc-shaped channel structure. The inner side of the arc-shaped channel structure is provided with an inner fixed guide rail on the guide rail frame, and the outer side of the arc-shaped channel structure is provided with an outer fixed guide rail on the guide rail frame. The connection between the single-chain guide rail and the double-chain guide rail is achieved by guiding the rollers of the single chain passing between them.

[0009] Preferably, the guide rail mechanism is further provided with movable guide rails at both ends, and the guide rail frame is provided with symmetrical mounting grooves at both ends, with movable guide rails respectively installed in the two mounting grooves. The guide rail frame is also provided with linear slide rails at its ends, and U-shaped frames are fixedly connected to the ends of the movable guide rails. The inner walls of the U-shaped frames are fixedly connected to the sliders on the linear slide rails, and the inner ends of the U-shaped frames are fixedly connected to the outer ends of the movable guide rails. Bearings are provided at the upper ends of the movable guide rails, and the bearings are interference-fitted with bearing spindles. The bottom ends of the bearing spindles are fixedly connected to the upper ends of the movable guide rails. The two movable guide rails form a double-chain linear passage output channel. When the two bearings are impacted by the wedge structure, they open to both sides. The bearing spindle drives the U-shaped frame and the two movable guide rails to move outward, and the output channel opens. When the double chain extending from the guide rail mechanism retracts, the double chain is decomposed into a single chain. When the single chain travels again along the arc-shaped groove structure between the inner and outer fixed guide rails where the two movable guide rails are located, the single chain presses the ends of the two movable guide rails and resets the two movable guide rails. The linear slide rail limits the final reset position of the movable guide rail by limiting the distance the slider moves inward.

[0010] Preferably, the end of the moving guide rail facing the double-chain guide rail is a wedge-shaped structure. The wedge-shaped structure is used to insert between the two single chains that mesh together to form a double chain and to decompose the double chain into two single chains as the double chain continues to move.

[0011] Preferably, the outer surface of a portion of the outer chain plate at the lower end of the single chain is further provided with a ball seat, the bottom end of which is connected to a universal ball, and the ball seats are evenly spaced at the lower end of the single chain.

[0012] Preferably, the guide frame between the double-chain guide rail and the single-chain guide rails on both sides is embedded with several drive sprocket units. Each drive sprocket unit includes two drive sprockets that are arranged opposite to the double-chain guide rail. The oppositely arranged drive sprockets simultaneously drive the adjacent double chains and single chains to move synchronously. The several drive sprocket units cooperate to interlock two single chains into a double chain or decompose a double chain into two single chains, and control the direction of movement of the double chain head.

[0013] Preferably, the drive mechanism includes a drive motor located at the lower end of the mounting plate. The drive motor is connected to a reducer via an output shaft. Several steering gears are connected in series at both ends of the reducer via universal couplings and transmission shafts. A gearbox is connected to the top of each steering gear. The top of the gearbox and the top of the reducer are fixedly connected to the mounting plate. The gearbox is connected to the central shaft of each drive sprocket assembly via gear transmission.

[0014] The beneficial effects of the multi-directional horizontal pushing chain drive device of the present invention are as follows:

[0015] (1) The double chain and single chain of the present invention do not require separate storage devices, which greatly reduces the vertical space and can be installed in a confined space environment.

[0016] (2) The present invention forms a "rigid" chain column by interlocking the chains, which can directly push and pull the items, and has the advantages of high load-bearing capacity, high rigidity and good stability.

[0017] (3) This invention can not only realize the automatic engagement and disengagement of the chain, but also realize the automatic extension and retraction of the chain, realize linear transmission in multiple directions, and has high reliability.

[0018] (4) The present invention ensures the stability and reliability of chain movement by driving multiple drive sprocket sets simultaneously.

[0019] (5) The present invention controls the rotation direction by motor, which can realize the forward and reverse rotation of the drive sprocket group, thereby realizing the extension, retraction and back-and-forth movement of the chain in the guide rail mechanism. It can realize long-distance transmission and short-distance precision linear reciprocating transmission within the guide rail mechanism through the double chain extension guide rail mechanism.

[0020] (6) The present invention controls the rotation speed and accuracy of the drive sprocket group by controlling the motor, thereby controlling the speed and position of the double chain extension, which can save the time of transporting goods and make it convenient for users to know the position of the goods.

[0021] In summary, this invention can simultaneously meet the requirements of long-distance, bidirectional, high speed, high rigidity, high precision, good stability, large load capacity, high efficiency, low noise, and small space occupation. It can also realize multi-directional linear transmission, that is, pushing or pulling linearly to both sides along the two ends of the guide rail mechanism, or pushing or moving back and forth linearly within the range of the guide rail mechanism. It can be widely used in fields such as automated parking systems, industrial automation, logistics warehousing, engineering machinery, military equipment, and precision manufacturing.

[0037] The technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] A multi-directional horizontal pushing chain drive device, such as Figure 1-8 As shown, the device includes a guide rail mechanism and an interlocking push chain. The interlocking push chain is a double-chain 02 structure composed of two single chains 01 interlocking. The double chain forms a rigid straight push chain, with the head of the straight push chain used to push the item. The guide rail mechanism includes a double-chain guide rail 016 located in the middle for the double-chain structure to travel, and single-chain guide rails 015 connected end-to-end to the double-chain guide rail and located on both sides of the double-chain guide rail. The length of the single chain is greater than the length of the single-chain guide rail, and satisfies the following requirements: allowing the double chain 02 to push or move the target item back and forth within the range of the double-chain guide rail; and allowing the double chain to output from the left or right end of the guide rail mechanism and push or pull the target item outside the guide rail mechanism.

[0040] In this embodiment, there are several structural forms of interlocking push chains in the prior art. For example, the invention patent with application number CN201180067044.0, which discloses an interlocking chain front and rear mobile device, discloses a technology in which two single chains are interlocked to form a double chain. The interlocking push chain of the present invention has a different structure, but the principle is the same. The contents not mentioned can be solved by the solutions of the prior art.

[0041] Taking a three-row chain as an example, such as Figure 1 As shown, the single chain in the interlocking push chain of the present invention includes a double-buckle inner chain plate 2, a double-buckle outer chain plate 1, a double-buckle middle chain plate 3, a sleeve 4, a pin 5, and a roller 6 (the assembly method is prior art and will not be described in detail). The double-buckle inner chain plate 2, the double-buckle outer chain plate 1, and the double-buckle middle chain plate 3 each include a connecting part for connecting with the pin or sleeve, and a locking part (similar to a key shape) extending upward along the connecting part. One end of the locking part has two protrusions, and the protrusions form a groove. When two single chains 01 are engaged, the opposing locking parts lock together to form a double chain 02. The double chain 02 has the load-bearing capacity in the horizontal push-pull direction, and can also withstand a certain load in any direction in the vertical plane. Of course, it is understood that the embodiments of the present invention are not limited to three-row chains. Double-row chains, multi-row chains, or single-row chains can be selected as needed.

[0042] Furthermore, the aforementioned double-chain structure constitutes a rigid linear push chain. The head of the linear push chain is used to push the item. Typically, a connecting seat is installed at the head of the single or double chain, and the item is pushed or pulled through the connecting seat. The term "item" used in this invention can be understood to encompass multiple meanings, including goods or related components in a mechanical structure. Through the linear transmission of this invention, various application effects can be achieved. For example, it can be used to push or pull items left or right along the direction of the guide rail mechanism, or to move items linearly a long distance along this direction. In certain special cases, such as when a component in a precision machine needs to move back and forth repeatedly, it can be used as follows... Figure 3 As shown, this component is connected between the two heads of the double chain. The double chain pulls the component back, thereby assisting the precision machinery in completing accurate linear movements. Other applications are not described in detail here. Based on the above description, it can be understood that this invention can achieve linear transmission in multiple directions, including: pushing or moving the target item within the range of the double chain guide rail; and outputting the double chain from the left or right end of the guide rail mechanism and pushing or pulling the target item outside the guide rail mechanism.

[0043] like Figure 1-6 As shown, unlike traditional double-speed chains or other rigid chain guides, the chain rotation plane of this device is horizontal, which can greatly reduce the vertical space. In addition, through the design of the chain guide rail, this device does not require a separate chain storage device.

[0044] Example 2

[0045] Based on Example 1, this example discloses:

[0046] like Figure 2-8 As shown, the guide rail mechanism includes a mounting plate 14 and a guide rail frame 03 disposed on the upper surface of the mounting plate 14. The middle of the guide rail frame 03 forms a first channel 07 for mounting a double-chain guide rail. Second channels 08 for mounting single-chain guide rails are located on both sides of the first channel 07. The two ends of the first channel and the two ends of the second channels on both sides are interconnected according to the trajectory of the single chain. A drive mechanism is provided at the bottom of the mounting plate 14. The drive mechanism is connected to several drive sprocket sets 09 disposed within the guide rail frame, and the single and double chains are driven to move together by the several drive sprocket sets 09. The coordinated operation of the several drive sprocket sets 09 achieves the following effects: firstly, it makes the chain movement more stable; secondly, it makes the chain and sprocket meshing more accurate; and thirdly, it increases the length of the extended chain. The drive mechanism is installed below the chain's movement trajectory (i.e., below the mounting plate 14), saving installation space.

[0047] Example 3

[0048] Based on Example 2, this example discloses:

[0049] like Figure 1 As shown, the single chain is a roller chain structure. The double chain guide rail includes short wear-resistant guide rails 05 located on the inner walls of both sides of the first channel 07. The short wear-resistant guide rails 05 on both sides are in rolling friction engagement with the rollers 6 on both sides of the double chain. The single chain guide rail includes a long wear-resistant guide rail 04 located on the inner surface of the outer wall of the second channel and a short wear-resistant guide rail 05 located on the outer surface of the inner wall of the second channel 08. The rollers of the single chain 01 are in rolling friction engagement with the adjacent long wear-resistant guide rail and short wear-resistant guide rail. The difference between the long wear-resistant guide rail and the short wear-resistant guide rail is that the width of the cross-section of the long wear-resistant guide rail is greater than the width of the cross-section of the short wear-resistant guide rail.

[0050] In this embodiment, the long and short wear-resistant guide rails are made of ultra-high molecular weight polyethylene, which has good wear resistance, low coefficient of friction, low water absorption, impact resistance, and light weight.

[0051] Example 4

[0052] Based on Example 3, this example discloses:

[0053] like Figure 5As shown, the connection part at the end of the single-chain guide rail and the double-chain guide rail is an arc-shaped channel structure 010. The inner side of the arc-shaped channel structure 010 is provided with an inner fixed guide rail 15 on the guide rail frame, and the outer side of the arc-shaped channel structure 010 is provided with an outer fixed guide rail 16 on the guide rail frame. The inner fixed guide rail and the outer fixed guide rail are connected to the single-chain guide rail and the double-chain guide rail by guiding the rollers of the single chain passing between them.

[0054] Example 5

[0055] Based on Example 4, this example discloses:

[0056] like Figure 5-7 As shown in Figure 13, the guide rail mechanism is further provided with movable guide rails 17 at both ends. The guide rail frame 03 is provided with mounting grooves 011 symmetrically at both ends, and movable guide rails 17 are respectively provided in the two mounting grooves 011. The guide rail frame is also provided with linear slide rails 18 at the ends. U-shaped frames 19 are fixedly connected to the ends of the movable guide rails. The inner wall of the U-shaped frame 19 is fixedly connected to the slider on the linear slide rail 18. The inner end of the U-shaped frame 19 is fixedly connected to the outer end of the movable guide rail 17. Bearings 21 are respectively provided at the upper end of the movable guide rail 17. The bearings 21 are interference-fitted with bearing spindles 22. The bottom end of the bearing spindles 22 is fixed to the upper end of the movable guide rail 17. The connection between the two movable guide rails 17 forms a linear output channel for the double chain 02. When the two bearings 21 are impacted by the wedge structure, they open to both sides. The bearing spindle 22 drives the U-shaped frame 19 and the two movable guide rails 17 to move outward, and the output channel opens. When the double chain 02 extending from the guide rail mechanism retracts, the double chain 02 is decomposed into a single chain. When the single chain 01 travels again along the arc-shaped groove structure 010 between the inner and outer fixed guide rails where the two movable guide rails are located, the single chain 01 squeezes the ends of the two movable guide rails 17 and resets the two movable guide rails 17. The linear slide rail 18 limits the final reset position of the movable guide rail 17 by limiting the distance the slider moves inward.

[0057] like Figure 6 , 7 As shown, when it is necessary to extend the double chain 02 from both ends of the guide rail mechanism, a bumper 23 can be installed on the transported item. The head of the double chain is connected to the item through a connector. Since the front end of the bumper 23 is a wedge-shaped structure, after the bumper contacts the bearing, it drives the moving guide rail 17 to move to both sides through the bearing spindle, and the double chain extends out from the guide rail mechanism, thereby realizing the long-distance transportation of the item.

[0058] Example 6

[0059] Based on Example 5, this example discloses:

[0060] like Figure 6 ,13 As shown, the moving guide rail has a wedge-shaped structure at one end 012 facing the double chain guide rail. The wedge-shaped structure is used to insert between the two single chains 01 that mesh together to form a double chain 02 and decompose the double chain 02 into two single chains 01 as the double chain 02 continues to move. Then, the two single chains return to the single chain guide rail along the arc-shaped channel structure 010.

[0061] like Figure 1 As shown, the outer surface of a portion of the outer chain plate at the lower end of the single chain 01 is also provided with a ball seat 7, and a universal ball 8 is connected to the bottom end of the ball seat. The ball seats 7 are evenly spaced at the lower end of the single chain. By setting the ball seats and universal balls, the smoothness and stability of the single chain and double chain operation are improved.

[0062] Example 7

[0063] Based on Example 6, this example discloses:

[0064] like Figure 1 , 3 As shown in Figures 5 and 6, the guide frame 03 between the double-chain guide rail and the single-chain guide rails on both sides is embedded with several drive sprocket units. Each drive sprocket unit includes two drive sprocket sets 09 that are arranged opposite to each other with respect to the double-chain guide rail. The oppositely arranged drive sprocket sets 09 simultaneously drive the adjacent double chain 02 and single chain 01 to move synchronously. The several drive sprocket units cooperate to realize the interlocking of two single chains into a double chain or the decomposition of a double chain into two single chains, and control the direction of movement of the double chain head. Figure 5 , 6 A partial structural diagram of the guide rail mechanism is provided, in which the running trajectories of single and double chains can be referenced. Figure 3 .

[0065] Example 8

[0066] Based on Example 7, this example discloses:

[0067] like Figure 2 As shown, the drive mechanism includes a drive motor (a common structure, not shown) located at the lower end of the mounting plate 14. The drive motor is connected to a reducer via an output shaft. Several steering gears 9 are connected in series at both ends of the reducer via universal couplings and a transmission shaft 12. A gearbox 10 is connected to the top of each steering gear 9. The top of the gearbox 10 and the top of the reducer are fixedly connected to the mounting plate 14. The gearbox 10 is connected to the central shaft of each drive sprocket set 09 via gear transmission.
