Description

Technical Field

[0001] This utility model relates to a logistics equipment, and more specifically, a conveying device. Background Technology

[0002] Currently, the adaptability of chain-connected loading systems is very poor. This is reflected in the fact that the chains of chain-connected loading systems are used in conjunction with pallets. Due to the variety of pallet sizes and the different lateral spans between pallet legs, and the fixed lateral spacing between chains, the contact area between the pallet legs and the chain is insufficient, and in some places, there is even no contact at all. As a result, the safety and reliability of loading goods cannot be guaranteed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a conveying device and an overall loading system equipped with the conveying device. The position of each set of chain components on the conveying device is adjustable in the lateral direction, so that the lateral spacing between the chains of the chain components is adjustable, effectively solving the problem of mismatch between the lateral spacing between the chains and the lateral span between the pallet legs, and meeting the conveying needs of pallets of different specifications.

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

[0005] A conveying device, characterized by the following structural features:

[0006] It is used in an integrated loading system and is used in conjunction with pallets for pallet transport; the conveying device includes a conveying frame, a chain assembly, and a moving device.

[0007] The conveyor frame is used to support the chain assembly and install the moving device, and is also used for the assembly between the conveyor device and the overall loading system;

[0008] The chain assembly is provided in multiple sets. Each set of chain assemblies includes a chain frame, a sliding sleeve and a chain mounted on the chain frame, a drive conveyor sprocket, a driven conveyor sprocket, and a chain drive device. The chain frame is fitted onto the conveyor frame through the sliding sleeve. Under the action of external force, it can slide horizontally on the conveyor frame in the transverse direction. The chain is used to support the pallet and is wound between the drive conveyor sprocket and the driven conveyor sprocket. The chain drive device drives the drive conveyor sprocket to rotate and drives the chain to run in the longitudinal direction.

[0009] The moving device is installed on the conveying frame and is configured with at least one for each group of chain components. Each group of chain components can be laterally displaced on the conveying frame by the drive of the matching moving device, which is used to adjust the lateral spacing between the chains of each chain component.

[0010] The pallet to be transported spans across a series of chain assemblies. The number of pallet legs is the same as the number of chains. Each leg rests on the upper end of its respective chain, and the lateral spacing between adjacent chains is set according to the lateral span between the adjacent legs they support.

[0011] The structural features of this utility model also lie in:

[0012] The mobile device includes a mobile drive device and a connecting frame. The mobile drive device is mounted on the conveying frame and drives the chain frame through the connecting frame, causing the entire chain assembly to move laterally on the conveying frame through the sliding sleeve.

[0013] The moving drive device is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder.

[0014] In the chain assembly, the chain drive device includes a drive motor and a transmission mechanism. The drive motor drives the chain, which is then transmitted through the transmission mechanism to rotate the active conveyor sprocket.

[0015] The transmission mechanism is a chain drive mechanism. The active transmission sprocket is driven to rotate by a drive motor, and the axle of the driven transmission sprocket is used as the power output shaft. The power output shaft is coaxially connected to the axle of the active transmission sprocket.

[0016] This utility model also proposes an integrated vehicle mounting system, including:

[0017] The base frame, as the overall frame, is used to install the mobile lifting device, cargo shaping device, conveying power device, and the aforementioned conveying device;

[0018] The mobile lifting device is used to adjust the overall position of the entire loading system, including both height and horizontal position.

[0019] The cargo shaping device is used to adjust the width of the cargo on the conveying device;

[0020] The conveying device is driven by a conveying power unit and can move forward or backward along the longitudinal direction on the base frame.

[0021] Compared with existing technologies, the beneficial effects of this utility model are reflected in:

[0022] This invention uses a sliding sleeve to movably assemble each chain assembly onto the conveyor frame in the lateral direction. Each chain assembly is equipped with at least one moving device, which is used to adjust the position of the chain assembly on the conveyor frame in the lateral direction. This allows the lateral spacing between the chains to be adjusted, thus adapting to different lateral span sizes between the legs of pallets of different specifications. This ensures that the pallet can be placed stably on each chain and make full contact with the chain, guaranteeing the reliability of the conveying. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Please refer to Figures 1 to 5 In this embodiment, the conveying device is applied to the overall loading system and is used in conjunction with the pallet 4 to convey the pallet 4; the conveying device 1 includes a conveying frame 11, a chain assembly, and a moving device;

[0041] The conveyor frame 11 is used to support the chain assembly and install the moving device, and is also used for the assembly between the conveyor device 1 and the overall loading system.

[0042] The chain assembly is provided in multiple sets. Each chain assembly includes a chain frame 21, a sliding sleeve 22, a chain 23 mounted on the chain frame 21, a drive conveyor sprocket 24, a driven conveyor sprocket 25, and a chain drive device. The chain frame 21 is assembled on the conveyor frame 11 through the sliding sleeve 22. Under the action of external force, it can slide horizontally on the conveyor frame 11 in the transverse direction through the sliding sleeve 22. The chain 23 is used to support the pallet 4 and is wound between the drive conveyor sprocket 24 and the driven conveyor sprocket 25. The chain drive device drives the drive conveyor sprocket 24 to rotate and drives the chain 23 to run in the longitudinal direction.

[0043] A moving device is installed on the conveyor frame 11, and at least one is configured for each chain assembly. Each chain assembly can be laterally displaced on the conveyor frame 11 by the drive of the matching moving device, which is used to adjust the lateral spacing between the chains 23 of each chain assembly.

[0044] The pallet 4 to be transported spans across the chain 23 of multiple chain assemblies. The number of legs 41 of the pallet 4 is the same as the number of chains 23. Each leg 41 is placed on the upper end of each chain 23 in a corresponding manner. The lateral spacing between adjacent chains 23 is set according to the lateral span between the adjacent legs 41 they support.

[0045] The structural features of this utility model also lie in:

[0046] The moving device includes a moving drive device 31 and a connecting frame 32. The moving drive device 31 is mounted on the conveying frame 11. The connecting frame 32 pulls the chain frame 21, causing the chain assembly to move laterally on the conveying frame 11 through the sliding sleeve 22.

[0047] The mobile drive device 31 is an electric cylinder, hydraulic cylinder, or pneumatic cylinder, and the actuator end is hinged to the connecting frame 32.

[0048] In the chain assembly, the chain drive device includes a drive motor 26 and a transmission mechanism. The drive motor 26 drives the chain, which in turn drives the active conveyor sprocket 24 to rotate through the transmission mechanism.

[0049] The transmission mechanism is a chain drive mechanism. The drive sprocket 27 is driven to rotate by the drive motor 26, and the axle of the driven sprocket 28 is used as the power output shaft. The power output shaft is coaxially connected to the axle of the drive conveyor sprocket 24.

[0050] The structure of tray 4 is as follows Figure 6 As shown, the bottom of the pallet 4 has multiple rows of legs 41, with each row of legs 41 spaced laterally and gaps between them for the forks to pick up the food. Figure 5 The widths of the three rows of legs 41 on the middle pallet 4 are W1, W2, and W3, respectively, and the lateral spans between adjacent legs 41 are L1 and L2, respectively. Correspondingly, three sets of horizontally continuous chain assemblies are used on the conveying device 1 to convey the pallet 4. The lateral spacing between these three sets of chain assemblies should be adjusted to match the lateral span between the three rows of legs 41 on the pallet 4. The adjustment method for each set of chain assemblies can be found in the following:

[0051] Driven by the mobile drive device 31, the chain frame 21 is pulled by the connecting frame 32, so that the chain frame 21 is laterally displaced on the conveying frame 11 through the sliding sleeve 22. By adjusting the position of each chain assembly on the conveying frame 11, the lateral spacing between adjacent chain assemblies is adjusted so that it is consistent with the lateral span between the four legs 41 of the pallet.

[0052] Once the positions of the three chain components are adjusted, they can jointly support the pallet 4 via chain 23. The chain drive device drives chain 23 to move, carrying the pallet 4 longitudinally.

[0053] Reference Figures 7 to 9 Based on the aforementioned conveying device 1, this embodiment also proposes an overall loading system, including:

[0054] The base frame 51 serves as the overall frame and is used to install the mobile lifting device 52, the cargo shaping device 53, the conveying power device 54, and the aforementioned conveying device 1.

[0055] The mobile lifting device 52 is used to adjust the overall position of the loading system, including the height position and the horizontal position, so that the overall loading system matches the position and height of the car body, container, etc. for docking.

[0056] Cargo shaping device 53 is used to adjust the width of cargo on conveying device 1 to ensure that the width of cargo matches the inner width of carriages, containers, etc.

[0057] The conveying device 1 is driven by the conveying power device 54 and can move forward or backward along the longitudinal direction on the base frame 51.

[0058] The bottom of the conveying device 1 is equipped with rollers 12. During the process of the whole being driven by the conveying power device 54 to move forward or backward along the conveying direction, the rollers 12 always maintain rolling contact with the bottom frame 51.

[0059] Further configuration: the driving force provided by the conveying power unit 54 drives the main drive sprocket to rotate, causing the main conveying chain wound between the main drive sprocket and the main driven sprocket to rotate forward or backward. The conveying device 1 is installed on the upper end of the main conveying chain and moves forward or backward longitudinally as the main conveying chain rotates.

[0060] When loading goods using the overall loading system:

[0061] After the conveying device 1 has adjusted each chain assembly of the pallet 4, it places the pallet 4 on the chain 23 of each chain assembly.

[0062] The chain drive device drives the chain 23 of the chain assembly to move forward longitudinally, moving the previous pallet 4 it supports forward, and then placing the next pallet 4. The chain drive device drives the chain 23 of the chain assembly to move forward longitudinally again, moving the two previous pallets 4 it supports forward, and then placing the next pallet 4. This process is repeated until all the pallets 4 on the conveyor device 1 are stacked.

[0063] The conveying power unit 54 drives the conveying device 1 carrying the goods to move forward longitudinally and deliver it to the designated position.

[0064] The conveyor power unit 54 drives the conveyor device 1 to move backward, while the chain drive unit drives the chain 23 of the chain assembly to move forward longitudinally. The two work in sync, leaving the goods in the car or container and completing the loading.
