Description

Technical Field

[0001] This invention belongs to the field of chain drive technology, specifically relating to a meshing and pushing chain device with a guiding component. Background Technology

[0002] Automated equipment is ubiquitous in both manufacturing and daily life. As automation applications become increasingly diverse, these devices are constantly evolving towards miniaturization, automation, and intelligence. Linear drive systems are an indispensable part of automated equipment, and customer demands for them are constantly rising. Some specific application scenarios require linear drive systems to possess characteristics such as self-guiding, small size, large stroke, mobility, and high load capacity. Currently, common linear drive systems on the market, such as push chains, linear motors, rack and pinion systems, screws, and hydraulic systems, cannot simultaneously meet all these requirements. Linear motors, rack and pinion systems, screws, and hydraulic systems are all relatively large, making them unsuitable for use in confined spaces. Push chain devices have the advantages of small size and large stroke; however, when pushing objects, many push chain devices rely on a single push chain, resulting in low chain stability and a lack of guiding mechanisms, leading to poor performance. Utility Model Content

[0003] This invention discloses an meshing push chain device with a guiding component, which meets the requirements of self-guiding, small size, large stroke, mobility, and high load in special application scenarios. In addition, it also features high precision, low production and maintenance costs, reversible use, and adaptive contact surface. By setting up a first push chain system and a second push chain system driven by the same drive mechanism, push chain one and push chain two can push objects synchronously, which greatly improves the stability of the push chain operation. By setting up the guiding component, the stability of the push chain is further improved while controlling the accuracy of the push chain movement trajectory.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A meshing push chain device with a guide component includes a first push chain system and a second push chain system arranged opposite to each other. A drive mechanism is provided between the first push chain system and the second push chain system. The drive mechanism is used to simultaneously drive the first push chain system to output or retract a push chain one and the second push chain system to output or retract a push chain two. A connecting block is fixedly provided at the top of the push chain one and the push chain two respectively. A top plate is provided at the top of the connecting block. The two connecting blocks are fixedly connected by a connecting plate. The connecting plate is connected to the bottom of the first push chain system and the second push chain system through a guide component.

[0006] Preferably, the drive mechanism includes a drive motor and a dual-outlet reducer connected to the drive motor, the motor shafts of the first push chain system and the second push chain system are coaxial and opposite to each other, and the dual-outlet reducer is connected to the motor shafts on both sides respectively.

[0007] Preferably, both the first push chain and the second push chain are formed by meshing and connecting the first chain and the second chain. The bottom left and right sides of the first push chain system and the second push chain system are provided with a first storage part and a second storage part for storing the first chain and the second chain. A drive part is connected between the first storage part and the second storage part. The front and rear ends of the bottom of the guide component are fixedly connected to the outer walls of the oppositely arranged first storage parts. The drive mechanism is located between the oppositely arranged second storage parts.

[0008] Preferably, the guiding component is a mast-type structure, which guides the movement along the predetermined trajectory of push chain one and push chain two.

[0009] Preferably, an adaptive structure, which is a spherical bearing, is also connected between the top plate and the top of the connecting block.

[0010] The advantages of this novel meshing push chain device with a guide component are as follows:

[0011] 1. This new type of product meets the requirements of special application scenarios such as self-guided design, small size, large stroke, mobility, and high load capacity. In addition, it also features high precision, low production and maintenance costs, reversible use, and adaptive contact surface.

[0012] 2. This new invention, by setting up a first push chain system and a second push chain system driven by the same drive mechanism, enables push chain one and push chain two to push objects synchronously. Push chain one and push chain two are also connected by a connecting plate, which greatly improves the stability of the push chain operation process.

[0013] 3. By setting up a guide component, this new invention further improves the stability of the push chain while controlling the accuracy of its movement trajectory.

[0014] 4. This new type connects the connecting block and the top plate through a spherical bearing, which can adapt to uneven ground or cargo contact surfaces, thus improving the device's adaptability to complex operating environments. Attached Figure Description

[0021] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0022] The following embodiments can be understood as a part of the local structure or method of the present invention, or as a combination of embodiments to explain the connotation of a larger range of structures or methods of the present invention.

[0023] Example 1

[0024] A meshing push chain device with a guiding component, such as Figure 1-5 As shown, the system includes a first push chain system 16 and a second push chain system 17 arranged opposite to each other. A driving mechanism is provided between the first push chain system 16 and the second push chain system 17. The driving mechanism is used to simultaneously drive the first push chain system 16 to output or retract push chain 10 and the second push chain system 17 to output or retract push chain 2. The top of push chain 10 and push chain 2 are respectively fixedly provided with connecting blocks 7. The top of the connecting block 7 is provided with a top plate 9. The two connecting blocks 7 are fixedly connected by a connecting plate 19. The connecting plate 19 is connected to the bottom of the first push chain system 16 and the second push chain system 17 through a guide component 18.

[0025] The first push chain system 16 and the second push chain system 17 of this novel invention both adopt a meshing push chain system disclosed in patent document CN220131061U. For details of its specific structure and principle, please refer to the contents of that patent.

[0026] This new type of device adopts a dual push chain structure. The top of push chain one and push chain two are respectively provided with connecting blocks, and the two connecting blocks are connected by a connecting plate, which increases the stability of the device. The drive mechanism connects two motor shafts through a double-outlet reducer, so that push chain one and push chain two can maintain synchronization. The guide component increases the horizontal load-bearing capacity of the push chain and can provide guidance and support when the load deviates from the load-bearing center of the push chain device.

[0027] Example 2

[0028] like Figure 1 As shown, the drive mechanism includes a drive motor 21 and a double-outlet reducer 20 connected to the drive motor 21. The motor shafts 15 of the first push chain system 16 and the second push chain system 17 are coaxially opposite each other, and the double-outlet reducer 20 is connected to the motor shafts 15 on both sides respectively. Power is provided by the drive motor and transmitted to the two motor shafts through the double-outlet reducer. The two motor shafts synchronously drive the sprockets in the first push chain system 16 and the second push chain system 17 to rotate, and the two sprockets synchronously drive the first push chain and the second push chain to rise and fall.

[0029] Example 3

[0030] like Figure 1-5 As shown, both push chain one and push chain two are formed by the meshing connection of chain one and chain two. The bottom left and right sides of the first push chain system 16 and the second push chain system 16 are provided with a first storage part and a second storage part for storing chain one and chain two. A drive part is connected between the first storage part and the second storage part. The front and rear ends of the bottom of the guide component are fixedly connected to the outer wall of the oppositely arranged first storage part, and the drive mechanism is located between the oppositely arranged second storage parts.

[0031] In this embodiment, the specific structure of the first push chain system 16 and the second push chain system 17 is the same as that of an interlocking push chain system disclosed in patent document CN220131061U. Any content not mentioned is solved by existing solutions.

[0032] Example 4

[0033] like Figure 1 As shown, the guide component 18 is a mast-type structure. The mast-type structure guides the push chain 10 and the push chain 2 along the set movement trajectory, thereby improving the stability of the push chain operation.

[0034] like Figure 3 As shown, an adaptive structure, namely a joint bearing 8, is also connected between the top plate 9 and the top of the connecting block 7.

[0035] In this embodiment, the connecting block 7 is connected to the top plate 9 via the spherical bearing 8. The top plate 9 can rotate and, to a certain extent, can adapt to the contact surface of goods or uneven ground.

[0036] The working principle of this new type:

[0037] like Figure 2 As shown, the meshing push chain, driven by the sprocket 14, separates in the first and second storage sections and coils along the guide rail. It meshes in the chain output channel of the drive section as push chain one or push chain two. Driven by the sprocket, push chain one or push chain two achieves vertical pushing and retraction.

[0038] like Figure 1 As shown, the drive mechanism of this novel design is positioned between the first push chain system 16 and the second push chain system 17, further saving space. After the drive motor outputs power, it transmits the power to two motor shafts via a double-outlet reducer. The motor shafts drive sprockets to drive two meshing push chains (push chain one and push chain two) to move synchronously up and down, pushing the object. A connecting plate connects the connecting blocks at the top of push chain one and push chain two, improving the stability of the push chains. The guide assembly provides guidance for the push chains, enhancing their ability to bear horizontal loads and further improving their stability. It also improves the efficiency of linear transmission and the service life of the push chains.

[0039] like Figure 3 As shown, this new type of bearing enables the top plate to adapt to uneven contact surfaces, making it suitable for complex operating environments.

[0040] like Figure 1 , 2 As shown, the first push chain system 16 and the second push chain system 17 adopted in this new invention can both fully retract chain one and chain two through sprocket drive, thereby greatly reducing the initial height of the top plate.

[0041] like Figure 1 , 2 As shown, the push chain is driven to extend and retract by a sprocket. The sprocket is driven by a drive motor, which can stop and start at any position to ensure stopping accuracy.

[0042] like Figure 1 As shown, this invention can also be used in reverse, that is, the top plate is in contact with the ground, and the storage box of the first push chain system 16 and the second push chain system 17 is connected to the object being pushed. For example, it can be installed on the bottom of a fork arm, pallet or other structure. The top plate pushes the object in reverse by contacting the ground, which improves the installation diversity, convenience and adaptability of the device.
