Description

Technical Field

[0001] This utility model relates to the field of forklift unloading technology, specifically to a forklift fork head structure for container unloading. Background Technology

[0002] Containers are standardized containers used for transporting goods, typically by sea, land, and rail. They are manufactured according to the specifications of the International Organization for Standardization (ISO) and are suitable for various modes of transport. During transportation, containers require the use of forklifts with driven forks to move them.

[0003] For example, a forklift head according to Chinese patent application number CN201721683444.5 includes a vertically arranged frame. The frame is composed of a top plate, a bottom plate, a first left side plate, and a second left side plate spliced ​​together end to end. A horizontal guide rod is connected between the first left side plate and the second left side plate. Two forks are slidably arranged on the guide rod and are arranged horizontally side by side. A vertical connecting plate is fixed to one side of the rear end of the forklift head. A frame-shaped seat is fixed to one side of the rear end of the connecting plate. The frame-shaped seat includes a horizontal arm and two forks protruding from both ends of the horizontal arm. The two forks are arranged downwards and bifurcated. The rear ends of the horizontal arm and the two forks protrude inwards to form a retaining edge. A slot is formed between the retaining edge and the connecting plate. The front end of the side wall of the slot forms a flared opening relative to the rear end of the side wall of the slot.

[0004] However, in actual use, after the container is placed on the fork and arrives at the unloading location, the fork is not convenient to automatically unload the container cargo. It is necessary to manually push it out or tilt the bottom of the cargo to one side before moving it out of the fork. However, fragile goods are easily damaged by this type of unloading, which affects the quality of the goods and results in poor performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a forklift fork head structure for container unloading. By driving an L-shaped pressure plate to move the container cargo, several rollers that are in contact with the bottom of the container cargo rotate around a pivot, reducing the friction between the bottom of the container cargo and the top of the support rod. This allows for the safe, labor-saving, and automated smooth ejection of cargo from the container, ensuring cargo integrity. It also significantly reduces the intensity and danger of manual handling, greatly improves unloading efficiency and operational safety, and effectively solves the problems in the background technology.

[0016] Compared with the prior art, this utility model provides a forklift fork head structure for unloading containers, which has the following beneficial effects:

[0017] 1. This utility model drives the second threaded rod to move the second threaded block horizontally, causing the L-shaped pressure plate at the bottom to push the container cargo to move. At the same time, during the movement of the container cargo, several rollers that are in contact with each other at the bottom rotate around the rotating shaft, reducing the friction between the bottom of the container cargo and the top of the support rod. This allows the cargo to be pushed out of the container smoothly, safely, labor-savingly and automatically, ensuring the integrity of the cargo. It also significantly reduces the intensity and danger of manual handling, and greatly improves unloading efficiency and operational safety.

[0018] 2. This utility model adjusts the height between the lifting plate and the top plate to make the second motor fit tightly against the rear side wall of the container cargo. Then, the first threaded rod rotates to drive the first threaded block to rise and fall, thereby driving the container cargo pressed on the top to rise and fall. This not only effectively fixes the position of the cargo inside the container and prevents it from sliding or tipping over, but also provides a stable force base for the subsequent push of the second motor, significantly improving the safety and controllability of the unloading process.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, this utility model provides a forklift fork head structure for unloading containers, including a U-shaped bracket 1 fixedly installed on the front side of the forklift;

[0027] like Figure 1-3 As shown, the top of the U-shaped bracket 1 on the side away from the forklift is provided with a drive assembly 3 for automatically unloading container cargo. The drive assembly 3 includes a top plate 33, which is located on the side of the U-shaped bracket 1 away from the forklift. The bottom of the top plate 33 has two second drive grooves 34 distributed front and back. The two ends of the second drive groove 34 are connected by bearings to a second threaded rod 35. The second threaded rod 35 is connected by threads to a second threaded block 36. The bottom of the two second threaded blocks 36 is fixedly provided with the same L-shaped pressure plate 37.

[0028] A lifting plate 32 is fixedly provided at the bottom of the top plate 33 near the U-shaped bracket 1. A main plate 31 is provided at the bottom of the lifting plate 32, and the bottom end of the lifting plate 32 is located inside the top of the main plate 31. A bolt for fixing the main plate 31 and the lifting plate 32 is threadedly connected to one side of the top of the main plate 31, which facilitates the adjustment of the height between the main plate 31 and the lifting plate 32 to adapt to container cargo of different heights.

[0029] The bottom of the main board 31 is fixedly disposed between the top of one end of the two support rods 25 near the U-shaped bracket 1. The rear end of the top plate 33 away from the U-shaped bracket 1 has a second slot 7. The second motor 38 is fixedly disposed inside the second slot 7. The output shaft of the second motor 38 passes through one side of the top plate 33 and is fixedly connected to one end of the second threaded rod 35 on the rear side, so that the second motor 38 can drive the second threaded rod 35 to move horizontally.

[0030] By setting up the drive assembly 3, after the container cargo is forked up, when it needs to be placed, the second motor 38 inside the second slot 7 is controlled to work. The second motor 38 drives the second threaded rod 35 to rotate. The second threaded rod 35 drives the second threaded block 36 to move horizontally along the second drive slot 34, so that the L-shaped pressure plate 37 at the bottom pushes the container cargo to move. At the same time, during the movement of the container cargo, several rollers 27 that are in contact with the bottom of the container cargo rotate around the rotating shaft 26, reducing the friction between the bottom of the container cargo and the top of the support rod 25. Thus, the cargo is safely, labor-savingly and automatically pushed out of the container cargo, ensuring the integrity of the cargo. At the same time, it significantly reduces the intensity and danger of manual handling, and greatly improves unloading efficiency and operational safety.

[0031] like Figure 1 , 2As shown in Figure 4, the bottom of the U-shaped bracket 1 on the side away from the forklift is provided with an adjustment component 2 for driving the container cargo to rise and fall and press it. The adjustment component 2 includes two support rods 25, which are respectively fixed at the front and rear ends of the bottom of the U-shaped bracket 1 on the side away from the forklift. The top of the support rod 25 has a groove, and several horizontally distributed rotating shafts 26 are connected inside the groove through bearings. Rotating rollers 27 are fixed on the rotating shafts 26 to facilitate the loading or unloading of container cargo. The side wall of the U-shaped bracket 1 away from the forklift has two front and rear distributed first drive grooves 22. The top and bottom of the two first drive grooves 22 are connected to the first threaded rods 23 through bearings. The ends of the two support rods 25 near the U-shaped bracket 1 are respectively fixed to one side of the two first threaded rods 23, so that the first threaded rods 23 can drive the support rods 25 to rise and fall.

[0032] The U-shaped bracket 1 has a first slot 6 at the top rear end on the side away from the forklift. A first motor 21 is fixedly installed inside the first slot 6. The output shaft of the first motor 21 passes through the U-shaped bracket 1 and is fixedly connected to the top end of the first threaded rod 23 on the rear side, so that the first motor 21 can drive the first threaded rod 23 to rise and fall. Support piles 4 are fixedly installed at the bottom of the two support rods 25 away from the U-shaped bracket 1. The two support piles 4 and the front and rear sides of the bottom of the U-shaped bracket 1 are fixedly installed with moving wheels 5, so as to facilitate the movement of this utility model.

[0033] By setting the adjustment component 2, when the cargo is forked to the top of the two support rods 25, the bolts between the main board 31 and the lifting plate 32 are loosened according to the height of the container cargo. The lifting plate 32 is pushed to drive the top plate 33 to rise, so that the second motor 38 is pressed tightly against the rear side wall of the container cargo. Then, by controlling the first motor 21 inside the first slot 6 to work, the first motor 21 drives the first threaded rod 23 to rotate, so that the first threaded block 24 rises and falls along the rotating first threaded rod 23, thereby driving the container cargo pressed on the top to rise and fall. This not only effectively fixes the position of the cargo in the container and prevents it from sliding or tipping over, but also provides a stable force base for the subsequent push of the second motor 38, significantly improving the safety and controllability of the unloading process.
