Description

Technical Field

[0001] The present invention relates to the technical field of land transportation of large components, and in particular to an auxiliary device for handling large components in a container and a method for using the device. Background Art

[0002] For goods that need to be loaded into containers for long-distance transportation in import and export trade, such as steel structures and other steel components, due to the weight, large volume and non-detachable characteristics of the goods, the goods can only be packed on specific pallets and then loaded into the container together with the pallets. However, loading and unloading containers is a relatively laborious and difficult process. Usually, the loading process is to apply butter on the bottom of the container to reduce the friction between the cargo pallet and the container, and the pallet and goods are pushed into the container by brute force. When taking out the container, brute force is also used to pull out the container. Such loading and unloading operations will wear the bottom plate of the container, and often cause the goods to rub against the container, resulting in damage to the goods. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects and to provide an auxiliary device capable of automatically operating for container pallet handling and a method of using the same.

One end of the upper transverse shaft has a shaft step, which is connected to the driven force transmission member (106). The other end of the upper transverse shaft (105) has a slot. After the driven force transmission member (106) on the other side is connected, a retaining spring is installed to prevent the driven force transmission member from being separated from the shaft during movement. The active force transmission member (107) and the driven force transmission member (106) are both symmetrically arranged to ensure the stability of the lifting bracket (101) during movement. The upper part of the active force transmission member (107) is connected to the driven force transmission shaft (119), and the lower part is connected to the active force transmission shaft (109) to form a rotation pair.

For the convenience of maintenance, both places are connected by bolts; the lower cross shaft (104) is connected to the travel wheel (103), and the lower cross shaft (104) is provided with a plurality of steps and grooves for limiting the displacement of the driven force transmission member (106) and the crossbeam (102). A cylindrical rolling bearing is arranged inside the travel wheel (103) for reducing the travel resistance of the device;In actual use, the motor rotates to drive the reducer to rotate, thereby rotating the lead screw and driving the lead screw nut to move forward and backward, thereby driving the push-pull connector (110) and the active force transmission shaft (109) to move forward and backward, thereby causing the driven force transmission shaft (119) and the cargo lifting bracket (101) to move up and down;

[0008] The in-and-out box transmission module (2) comprises a motor (201), a driving sprocket (202), a chain (203), a driven sprocket (204), a transmission shaft (205), a driving wire rope drum (206), a transmission shaft support (207), a wire rope (208), a wire rope guide wheel (209), and a wire rope guide wheel (210) on a steel section.

[0009] The support track (3) is composed of a steel track (301) and a steel support (302). The steel track (301) is designed with a raised track, which fits exactly with the running wheel (103) to limit the running wheel to move exactly along the track direction. A square hole is provided on the upper surface of the end thereof for installing the wire rope guide wheel (210) on the steel and ensuring the passage of the wire rope. The remaining parts are bolt holes for bolting other parts thereto.

[0010] The transporting plate truck (4) comprises a plate (401), running wheels (402) and a transport plate connecting member (403), which is used to carry the loading and unloading device so that it is at the same height as the container on the truck. Generally, the height of the truck plate is 1.2 meters, so the height of the transport plate (401) can be designed to be coordinated with this height. In special circumstances, the lower part of the loading and unloading device can be raised or multiple jacks or other similar lifting devices can be set;

[0011] The cargo and pallet (5) are mainly characterized by a pallet consisting of a vertical support (501), a pallet bottom support (502), and a pallet lateral support (503), and a certain space is provided at the bottom thereof, so that the device can smoothly extend into and lift up the pallet.

[0013] Step 1: Place the goods on the pallet and pack the goods and pallet securely;

[0014] Step 2, start the motor (116) to rotate and drive the reducer (114) to rotate, and then the lead screw rotates to drive the lead screw nut to move forward and backward, thereby driving the push-pull connector (110) and the active force transmission shaft (109) to move forward and backward, and then the driven force transmission shaft (119) and the cargo lifting bracket (101) to lift the cargo lifting bracket (101), and then turn off the motor (116);

[0015] Step 3: Lift the cargo to the top of the device and place it on the device;

[0016] Step 4: Use a trailer head to drag the transport vehicle plate (4) of the packing device so that the rear end of the device is flush with the inner bottom surface of the container on the truck, ensuring that the running wheels (103) of the device can smoothly enter and exit the container;

[0017] Step 5, restart the motor (201) to drive the driving sprocket (202), and the driving sprocket (202) drives the driven sprocket (204) through the chain transmission, thereby driving the transmission shaft (205) to rotate, so that the driving wire rope drums (206) on both sides rotate coaxially with the transmission shaft, and synchronously drive the wire ropes (208) at both ends to generate traction, thereby driving the driven wire rope drum (118) to rotate. Since the driven wire rope drum (118) and the wire rope use the screw beam (102), the running wheel (103) and the entire cargo lifting device (1) to move along the track on the steel track (301) in the direction of the container, the motor (201) is turned off after the cargo is finally delivered to the corresponding position of the container;

[0018] Step 6, start the two motors (116) to lower the cargo into the container until the cargo lifting bracket (101) is separated from the bottom of the pallet and is in a completely load-free state, and then turn off the two motors (116);

[0019] Step 7: Restart the motor (201) to rotate in the reverse direction, and drive the steel wire rope and the cargo lifting device (1) to exit the container in the same manner, thus completing the loading of the container.

[0021] 1. Improve the efficiency of container loading and unloading;

[0022] 2. Reduce the damage to containers and cargo during loading and unloading;

[0023] 3. Compared with the traditional loading and unloading method of jacking in and pulling out, this method is safer, more efficient and reduces labor consumption. BRIEF DESCRIPTION OF THE DRAWINGS
