Description

Technical Field

[0001] This invention relates to the field of heavy-duty mobile loading technology, and more specifically to a horizontal multi-stage pushing mechanism suitable for heavy loads. Background Technology

[0002] Heavy-duty mobile loading technology is a crucial aspect of heavy industry development. With continuous advancements in heavy-duty turnaround and operational technologies worldwide, equipment has become more efficient and easier to operate, leading to rapid advancements in heavy-duty loading technology. Within the field of heavy-duty mobile loading technology, there is a constant pursuit of increasing deployable weight and efficiency. Currently, traditional heavy-duty mobile loading equipment typically relies on large lifting equipment, gantry cranes, large traction equipment, and other similar machinery.

[0003] Heavy-duty mobile loading equipment typically requires a large amount of space and is highly complex to operate. Furthermore, limitations imposed by ordinary workshops, docks, equipment power, and sea conditions prevent the installation of multi-stage push-pull loading equipment suitable for large, heavy-load horizontal loading. Summary of the Invention

[0004] In view of this, the present invention provides a horizontal multi-stage pushing mechanism suitable for heavy loads. This mechanism can realize the mechanized loading of heavy loads through a two-stage pushing mechanism. The pushing base, the load connecting device and the pushing extension device complete the horizontal multi-stage pushing and loading task of heavy loads. At the same time, it can accurately remove the heavy load placement platform.

[0005] A horizontal multi-stage pushing mechanism suitable for heavy loads includes a moving platform, a main drive device, a driven device, a pushing base, a pushing connecting seat, a pushing extension device, and a load connecting device. The main drive device and the driven device are mounted on the mobile platform. The push base is mounted on the chain between the main drive device and the driven device. The main drive device and the driven device form a transmission chain that drives the push base to move horizontally. The push connecting seat is fixedly connected above the push base. The load connecting device is fixedly connected to the push connecting seat. The load connecting device enables connection of various loads and fixation after arbitrary angle swing. After the load is pushed and loaded to complete the first stage of pushing, the center of gravity of the load enters the loading container. The load connecting device is removed, and the push extension device is installed on the push connecting seat. The second stage of pushing of the load is completed through the push extension device.

[0006] Furthermore, the load connection device includes a front tie rod, a rear tie rod, a ball head cover plate, a nut, and a connecting seat; One end of the front pull rod is equipped with a hook, which mates with a pre-reserved interface on the load. The other end of the front pull rod is a ball-and-socket structure. One end of the rear pull rod is a ball-head structure, and the other end is a threaded section. When installing the rear pull rod, the ball-head cover plate is first fitted. The front and rear pull rods are connected by the ball-and-socket, ball-head, and ball-head cover plate to form a long rod. The two long rods are connected by the hook of the front pull rod and the interface of the load. The threaded section of the rear pull rod passes through the connecting seat and is locked by a nut. The load is fixed on the connecting seat by the helical preload. The connecting seat has multiple pre-reserved interfaces for connection with the push connecting seat.

[0007] Furthermore, the main drive device uses a motor drive to output power, and the driven device is a fixed point at the other end of the chain drive. The power transmission is completed by the push base being installed on the chain between the main drive device and the driven device.

[0008] Furthermore, the bottom of the push base is provided with side limiting rollers and bottom bearing rollers, which effectively ensures that the push delay track runs smoothly under the power transmission of the chain drive.

[0009] Furthermore, the push extension device has interfaces on the panels at both ends for connecting to the push connection seat and the load connection device, and the push extension device has a reinforcing ring along the axial direction.

[0010] Beneficial effects: 1. The main drive device, driven device, push base, push connecting seat, push extension device and load connecting device of the present invention are all set on the moving platform. The push base is installed on the driven device. The main drive device and the driven device form a transmission chain to drive the push base to move horizontally. The push connecting seat is fixedly connected above the push base. The mechanism is compact and the connection is stable and reliable. The area occupied is equivalent to that of a 17.5-meter semi-trailer. It occupies little space and is suitable for a load of about 15 tons.

[0011] 2. The load connection device of the present invention uses two long rods to tighten and fix the load to the connecting seat by using the hook of the front pull rod to cooperate with the interface of the load. Since the front pull rod and the rear pull rod cooperate with the ball socket and the ball head, the load can swing at any angle during the fixing process and then be fixed with the triangular connecting seat. The connection interface is adjustable and controllable in all directions and is simple to operate.

[0012] 3. The multi-stage pushing mechanism of the present invention can achieve two-stage pushing by replacing the pushing extension device. It can not only push the load, but also accurately remove the heavy load placement platform, which has higher efficiency and flexibility.

[0013] 4. The load connection device, push connection seat and push extension device of the present invention are all provided with multiple connection ports, which can connect multiple loads in an efficient, safe and reliable manner. The connection device is installed on the push connection seat to realize load attitude adjustment and fixation. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] As attached Figure 1 As shown, this invention provides a horizontal multi-stage pushing mechanism suitable for heavy loads, mainly composed of a mobile platform 1, a main transmission device 2, a driven device 3, a pushing base 4, a pushing connecting seat 5, a pushing extension device 6, and a load connecting device 7. This mechanism aims to achieve mechanized loading of heavy loads, completing the horizontal multi-stage pushing and loading task of heavy loads through a two-stage pushing mechanism, and accurately removing the heavy load from the platform. It has advantages such as compact structure, simple operation, high efficiency, and strong flexibility.

[0018] Detailed structure of each component: The mobile platform 1 is the basic load-bearing component of the entire pushing mechanism. The main drive device 2, driven device 3, pushing base 4, pushing connecting seat 5, pushing extension device 6, and load connecting device 7 are all mounted on the mobile platform 1. It provides a stable installation and operating environment for other components, enabling the entire mechanism to move and operate as a whole.

[0019] As attached Figure 2 As shown, the main drive unit 2 uses a motor drive for power output, providing the main power source for the entire pushing mechanism. (See attached diagram.) Figure 3As shown, the driven device 3 is the fixed point at the other end of the chain drive, completing the power transmission within the effective stroke. It transmits the power output from the main drive device 2 to the push base 4, causing the push base 4 to move horizontally. The main drive device 2 and the driven device 3 form a transmission chain, ensuring stable power transmission and effective utilization.

[0020] As attached Figure 5 As shown, the bottom of the push base 4 is equipped with side limiting rollers, bottom bearing rollers, and chain connectors. The chain connectors connect the main drive device 2 and the driven device 3, forming a transmission chain that allows the push base 4 to move horizontally with the movement of the chain. The side limiting rollers and bottom bearing rollers of the push base are used to move horizontally along the guide rail grooves inside the moving platform when the push base rests on it, ensuring the stability of the pushing process. As the direct load-bearing component for pushing, the push base 4 achieves horizontal movement under power, providing a foundation for pushing heavy loads.

[0021] The pusher connector 5 is fixedly connected above the pusher base 4. It serves to connect the pusher base 4 and the load connecting device 7, and transmits the horizontal movement of the pusher base 4 to the load connecting device 7, thereby driving the heavy load to be pushed.

[0022] As attached Figure 4 As shown, the load connection device 7 includes a front pull rod 7-1, a rear pull rod 7-2, a nut 7-3, and a connecting seat 7-4. One end of the front pull rod 7-1 has a hook that mates with a pre-reserved interface on the load for connection; the other end has a ball-and-socket structure. One end of the rear pull rod 7-2 has a ball head structure, and the other end has a threaded section. The front pull rod 7-1 and the rear pull rod 7-2 form a long rod through the ball-and-socket connection. The two long rods connect to the load via the hook of the front pull rod 7-1 and the interface of the load. The threaded section of the rear pull rod 7-2 passes through the connecting seat 7-4 and is locked by the nut 7-3, using helical preload to fix the load to the connecting seat 7-4. The connecting seat 7-4 has multiple pre-reserved interfaces for connection to the push connecting seat 5, enabling a reliable connection between the load and the push connecting seat 5. Furthermore, since the front tie rod 7-1 and the rear tie rod 7-2 are connected by a ball joint and a socket, the load can be deflected at any angle during the fixing process and then fixed with the triangular connecting seat 7-4. The connection interface is adjustable and controllable in all directions, and the operation is simple.

[0023] As attached Figure 6 As shown, the push extension device 6 has interfaces on its end panels for connecting to the push connection seat 5 and the load connection device 7, used to connect to the push connection seat 5 and the load connection device 7 when secondary push is required. The push extension device 6 has a reinforcing ring along its axial direction, which enhances the strength and stability of the push extension device 6 and ensures that it can withstand a large load during the secondary push process.

[0024] The working process of push notification organizations: First-stage pushing: When heavy loads need to be loaded, the load is first connected to the pre-reserved interface on the load via the hook of the load connecting device 7. Then, the rear pull rod 7-2 is locked with nut 7-3 to fix the load on the connecting seat 7-4. Next, the transmission chain formed by the main drive device 2 and the driven device 3 drives the pushing base 4 to move horizontally. Since the pushing connecting seat 5 is fixedly connected above the pushing base 4, the load connecting device 7 is fixedly connected to the pushing connecting seat 5, thus realizing the first-stage pushing of the load. After the first-stage pushing is completed, the center of mass of the load enters the loading container.

[0025] Secondary pushing and load removal: Remove the load connecting device 7 and install the pushing extension device 6 on the pushing connecting seat 5. The secondary pushing of the load is completed through the pushing extension device 6. When a heavy load needs to be removed from the platform for turnover, the load connecting device 7 is connected to the pushing extension device 6 to place one end of the load on the platform. Then, the secondary pushing extension device is replaced with the primary load connecting device, which can safely and reliably remove the heavy load completely from the platform.

[0026] Meanwhile, when heavy loads need to be removed from the platform for turnover, the load is placed on the platform by connecting the push extension device 6 to the load connection device 7. Then, the secondary push extension device is replaced with the primary load connection device, which can safely and reliably remove the heavy load from the platform.

[0027] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
