Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of logistics and transportation, in particular to a heavy-duty fork frame. Background Art
[0002] The fork carriage is a key component of the forklift's working mechanism. When in use, it is mounted within the inner mast. Under external forces, the fork carriage moves up and down within the mast to enable the forklift to operate. The forks, also known as fork arms, are the components of the fork carriage used to carry cargo. They are typically made of sturdy metal and come in various lengths and load capacities to handle a variety of cargo types and weights.
[0003] Currently, existing forklifts connect to the forklift's lifting system, allowing them to move up and down to lift and lower cargo, enabling them to work with the forklift for transport. However, due to the lack of a structure on the forklift to restrict the horizontal movement of cargo, they are not suitable for pulling cargo for transport. Furthermore, the forks of existing forklifts typically consist of two L-shaped structures, with the vertical section serving as a support and the horizontal section as the working section for placing the cargo. While this flattened horizontal section ensures cargo remains stable during transport, it is difficult to insert into cargo, making it unsuitable for insertion and transport, such as transporting bales of straw. Utility Model Content

[0010] As an optional solution, two fork arms are provided, and the two fork arms are respectively provided at both ends of the frame body, and the top and bottom of the vertical section of the fork arm are detachably connected to the upper beam and the lower beam respectively.
[0011] As an optional solution, a lower protrusion is provided on one edge of the lower surface of the lower cross beam along the length direction, and two strip-shaped notches are provided at intervals in the middle of the lower protrusion; an upper protrusion is provided on one edge of the upper surface of the upper cross beam along the length direction, and the top and bottom of the vertical section of the fork arm are fixedly connected with an L-shaped block that can be engaged with the lower protrusion or the upper protrusion; the fork arm can be moved left and right along the frame body through the L-shaped block, and is restricted from moving forward and backward by the L-shaped block; the two fork arms are moved toward the middle of the frame body until the L-shaped blocks can respectively detach from the lower cross beam through the corresponding strip notches, thereby removing the two fork arms.
[0012] As an optional solution, two limit plates are provided, and the two limit plates are fixedly connected to the two ends of the frame respectively, and the limit plates abut against the end of the circular fork and the top of the fork arm.
[0013] As an optional solution, the hoop is sleeved on the front end opening of the rod sleeve.
[0014] Due to the adoption of the above technical solution, the utility model will have the following beneficial effects:
[0015] 1. By arranging a carrying member on one side of the frame and arranging the carrying member as a round fork, a traction rod or a fork arm; when it is necessary to insert the round fork for carrying, the round fork is detachably inserted into the fork sleeve and the other carrying members are removed, and the tip of the round fork is used to directly insert the round fork into the straw bale and then lift it for transportation and transfer; when it is necessary to pull the goods for carrying, one end of the traction rod is detachably inserted into the rod sleeve and the other carrying members are removed, and the other end of the traction rod is connected to the goods, and the goods are pulled by the traction rod for carrying; when it is necessary to move up and down to lift or lower the goods for carrying, the vertical section of the fork arm is detachably connected to the frame and the other carrying members are removed, and the horizontal section of the fork arm is used as the working part for forking the goods and then moved up and down for carrying. Compared with existing fork frames, the present invention can switch the carrying members according to different working conditions, making it convenient for carrying.
[0016] 2. A limit plate is installed on the other side of the frame, which abuts against the fork and fork arm. This prevents the fork and fork arm from moving backward when handling and stacking heavy cargo. Simultaneously, a hoop is installed on the rod sleeve, which tightens around the tow bar inserted in the rod sleeve, thus limiting the axial movement of the tow bar when pulling heavy cargo. Therefore, the installation of the limit plate and hoop prevents the fork, fork arm, and tow bar from separating from the frame due to the reaction force of the cargo when handling heavy, large-capacity loads, thereby improving safety.
