Description

Technical Field

[0001] The present invention relates to an automatic container loading platform. Background Art

[0002] Bamboo-based fiber composite material is a new type of building and engineering structural material processed through procedures such as defibrating bamboo into fibrous bamboo veneers, followed by drying, dipping in glue, drying, assembling the blanks, and gluing. The static bending strength of this material can reach over 350 MPa, the tensile strength reaches over 360 MPa, the compressive strength reaches over 140 MPa, and the elastic modulus reaches 27 GPa. It has good physical and mechanical properties and can be directly used for beams, columns, furniture, floors, etc., and is commonly known as bamboo steel.

[0003] The bamboo steel produced by our company is mainly for export, so it needs to be packed and loaded into containers. However, the existing loading methods are difficult to adapt to the bamboo steel products of our company: 1. The length of the bamboo steel products of our company can reach 6 m, and it is very difficult to load them with forklifts, with extremely low efficiency. Moreover, even if multiple forklifts work together, it generally takes 2 - 3 hours to load one container, and a personnel passage needs to be left inside the container to enable personnel to enter and cooperate during loading and unloading, but this will waste container space and pose a greater safety hazard, and there is a risk of workers being injured due to unskilled cooperation during loading and unloading; 2. The position of the container cannot be precise, resulting in the need to continuously adjust the positions of the forklift and the pallet during the loading process to make them fall in the appropriate positions, and the distances between the pallet and the end wall of the container and between the pallets are all manually assisted for confirmation, with low efficiency and also posing a safety hazard. Summary of the Invention

[0004] The present invention has developed an automatic container loading platform, which uses a special pallet in cooperation with the automatic container loading platform, can effectively improve the automation level of container loading, reduce the risk of workers being injured; and it only takes about 1 minute to load one container, greatly improving the work efficiency.

[0005] An automatic container loading platform, the automatic container loading platform includes a fixed frame 2, several first telescopic cylinders 3 are arranged on the upper end surface of the fixed frame 2, the first telescopic cylinders 3 are connected to the bottom surface of the longitudinal moving platform 4, and a traveling track is arranged on the upper end surface of the longitudinal moving platform 4; a transverse moving platform 7 is arranged above the longitudinal moving platform 4, the bottom surface of the transverse moving platform 7 is connected to a second telescopic cylinder 6, a traveling wheel 5 is arranged below the second telescopic cylinder 6, and the traveling wheel 5 can travel on the traveling track; a threaded hole 8 is opened on the transverse moving platform 7, the threaded hole 8 is penetrated and matched with a threaded rod 9, and an external thread of the threaded rod 9 and an internal thread of the threaded hole 8 form a screw pair; the threaded rod 9 is connected to a motor 12.

[0006] Further, a fixed platform 1 is arranged below the fixing frame 2, and the fixed platform 1 is preferably a steel frame.

[0007] Further, an end limiting block 10 is arranged at the end of the threaded rod 9, and a tail limiting block 11 is arranged at the other end of the threaded rod 9.

[0008] Further, synchronous laser locators 13 are symmetrically arranged on both sides of the fixing frame 2.

[0009] Further, a laser ranging device 14 is arranged at the end of the transverse movable platform 7.

[0010] Further, the length of the transverse movable platform 7 is set to be > 6m.

[0011] The pallet cooperating with the above-mentioned container automatic loading platform is special. As Figure 5 shown, most of the pallets are of the specification of double load-bearing surfaces and three support legs, but the pallet used in the present invention is of the specification of single load-bearing surface and double support legs, and the height of the support legs < the height of the transverse movable platform 7 + the maximum height of the second telescopic oil cylinder 6 + the height of the traveling wheel 5, and the height of the support legs > the height of the transverse movable platform 7 + the minimum height of the second telescopic oil cylinder 6 + the height of the traveling wheel 5.

[0012] A pallet cooperating with the above-mentioned container automatic loading platform, which comprises 1 load-bearing surface 15, and 2 support legs 16 are connected below the load-bearing surface 15, and a fork insertion space 17 is formed between the support legs 16. During operation, the pallet is placed on the transverse movable platform along the direction of the fork insertion space.

[0013] Further, the lower corners of the support legs 16 are of rounded corner structures, and preferably, rollers 18 are installed on the rounded corner structures.

[0014] The above-mentioned container automatic loading platform cooperates with the overhead crane 19, and the palletizing and loading efficiency is further improved.

[0015] Advantages of the present invention:

[0016] 1. The present invention uses a special pallet to cooperate with the container automatic loading platform, which can effectively improve the automation level of container loading, reduce the risk of worker injury; and the time required to load one container is only about 1 minute, greatly improving the work efficiency;

[0017] 2. When the container is on the ground, the container automatic loading platform does not require a fixed platform; when the container is on the vehicle, the height of the fixed platform is slightly lower than the height of the container bottom plate; it can be used in a variety of usage environments;

[0018] 3. The use of the end limiting block and the tail limiting block can effectively protect the screw pair and prevent it from being damaged due to excessive displacement;

[0019] 4. The synchronous laser locator can aim at the end wall of the container or the rearview mirror of the container transporter. The driver can accurately adjust the container based on the relative position of the infrared ray;

[0020] 5. When loading products, a laser distance measuring device is used to control the distance between the pallet and the container end wall, and between pallets, without manual assistance;

[0021] 6. When unloading the container, a forklift is used to lift one end of the pallet at the door panel, hook it and fix it, and then move backward to drag it out of the container. Since a 6m long bamboo steel pallet weighs 13t-13.5t, the weight is very large, resulting in great drag resistance, which can easily cause damage to the pallet. The corners under the pallet are set as rounded structures and rollers are installed to reduce drag resistance, facilitate unloading, and protect the pallet.

[0022] 7. Our company's 6m long bamboo steel products can be quickly palletized. When loading a 40-foot container, they can be loaded at one time through the container automatic loading platform, which greatly improves work efficiency and eliminates safety hazards.

[0034] Embodiment 1

[0035] An automatic container loading platform, the automatic container loading platform includes a fixed frame 2, a fixed platform 1 is arranged below the fixed frame 2, a plurality of first telescopic oil cylinders 3 are arranged on the upper end surface of the fixed frame 2, the first telescopic oil cylinders 3 are connected to the bottom surface of the longitudinally movable platform 4, and a traveling track is arranged on the upper end surface of the longitudinally movable platform 4; a laterally movable platform 7 is arranged above the longitudinally movable platform 4, the bottom surface of the laterally movable platform 7 is connected to a second telescopic oil cylinder 6, a traveling wheel 5 is arranged below the second telescopic oil cylinder 6, and the traveling wheel 5 can travel on the traveling track; a threaded hole 8 is opened on the laterally movable platform 7, the threaded hole 8 is in through-fit with a threaded rod 9, and the external thread of the threaded rod 9 and the internal thread of the threaded hole 8 form a screw pair; the threaded rod 9 is connected to a motor 12, an end limit block 10 is arranged at the end of the threaded rod 9, and a tail limit block 11 is arranged at the other end of the threaded rod 9; synchronous laser locators 13 are symmetrically arranged on both sides of the fixed frame 2; a laser ranging device 14 is arranged at the end of the laterally movable platform 7; the length of the laterally movable platform 7 is set to 13 m; a traveling crane 19 is arranged above the automatic container loading platform.

[0036] The tray cooperating with the above automatic container loading platform is of the specification of a single bearing surface and two support legs, and the height of the support leg < the height of the laterally movable platform 7 + the maximum height of the second telescopic oil cylinder 6 + the height of the traveling wheel 5, and the height of the support leg > the height of the laterally movable platform 7 + the minimum height of the second telescopic oil cylinder 6 + the height of the traveling wheel 5. This tray includes 1 bearing surface 15, 2 support legs 16 are connected below the bearing surface 15, a fork entry space 17 is formed between the support legs 16, the lower corners of the support legs 16 are of a rounded corner structure, and rollers 18 are installed on the rounded corner structure.

[0037] During operation, first place the pallet on the transverse movable platform along the direction of the fork-in space; then use a crane to lift the 6-meter-long bamboo steel onto the pallet and fix it to form a pallet; open the door panel of the container, then reverse the container transport vehicle, and adjust the attitude of the container transport vehicle to a proper position through the laser emitted by the synchronous laser locator; the first telescopic oil cylinder starts to work to lift the longitudinal movable platform to be flush with the bottom plate of the container; then the second telescopic oil cylinder jacks up for the first time to make the bottom surface of the support legs of the pallet higher than the bottom surface of the running wheels; then start the motor to send the transverse movable platform and the pallet thereon into the container; when the running wheels enter the container, the second telescopic oil cylinder jacks up in sequence for the second time to make the running wheels support on the bottom plate of the container; when the transverse movable platform continuously runs to the target position, it will be automatically prompted by the laser distance measuring device, which can prevent damage to the end wall of the container. When loading in sections, the distance between pallets can be adjusted; at this time, the second telescopic oil cylinder contracts, the support legs of the pallet fall on the bottom plate of the container, and at the same time, the transverse movable platform is disengaged from the pallet, and the motor reverses to retract the transverse movable platform and reset it.

[0038] The overall loading efficiency of the above-mentioned automatic container loading platform is very high, and there is no need for workers to enter the container for command and adjustment, so there is no safety hazard. In practice, the loading process of a 40-foot (12m long, limited load 28t) container only takes 1 minute.

[0039] At the same time, in practice, our company found that after the transverse movable platform enters the container, if there is no second telescopic oil cylinder jacking up to make the running wheels support on the bottom plate of the container, that is, only one set of telescopic oil cylinders is used, and the transverse movable platform transports the pallet through the walking track without setting the second telescopic oil cylinder and the running wheels. Due to the large load of the goods, the transverse movable platform is in a suspended state after entering the container and will be subjected to a strong torsional force in the vertical direction. After repeated use, the transverse movable platform will deform due to bending stress, affecting the matching with the threaded rod and causing certain losses.

[0040] After the loaded container arrives at the destination, it can be unloaded with the above-mentioned automatic container loading platform or a forklift can also be used: insert the forklift into the fork-in space, slightly lift one end, then fix the pallet, and the forklift moves backward to drag the pallet together with the 6-meter-long bamboo steel out. When unloading with a forklift, if the contact position between the support legs of the pallet and the bottom plate of the container is a sharp-cornered point contact, the dragging resistance is extremely large, and the pallet is easily damaged under the action of a large torque. Therefore, the lower corners of the pallet are provided with a rounded structure and rollers, which not only reduce the dragging resistance and facilitate unloading, but also can effectively protect the pallet.

[0041] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
