TECHNICAL FIELD

[0001] The utility model relates to engineering machinery technical field, especially a simple cargo fork. BACKGROUND

[0002] As a kind of widely used engineering machinery, loader plays an important role in various engineering scenes. Its conventional shovel loading operation is mainly completed by shovel, which can efficiently shovel, carry and operate loose materials such as sand, soil and the like.

[0003] However, there are special conditions in actual operation. For example, when facing regular stone, square box and other regular objects, using shovel to load and unload will face many problems. Due to the structural characteristics of shovel, it is difficult to accurately grasp during loading and unloading, which can easily cause damage such as bumping and extrusion to the object, and the loading and unloading efficiency is low. Therefore, in these special conditions, special tools-fork is needed. The working principle of fork is similar to that of forklift, which loads and unloads objects by forking, which can effectively avoid damage to regular objects and meet the specific operation requirements. In the prior art, the structure of fork is various. One of the common fork structures is integral type ( Figure 1 ), when loader needs to use fork, the operation process is more complicated. First, the shovel is disassembled from the loader, and then the integral fork is installed. The whole process not only consumes a lot of time, but also has high technical requirements for the operator, and increases the labor intensity. In addition, the Chinese utility model patent with publication number CN208394720U also discloses a loader fork ( Figure 2 ). The fork includes two forks, and a bolt penetrating up and down is arranged at the rear end of the two forks, and the fork and the shovel body are fixed by the bolt.

[0004] Although this structure simplifies the installation process of fork to some extent, and does not need to disassemble the shovel as a whole, there are still obvious defects in actual use. Since the existing fork is only fixed with the shovel body by the bolt penetrating up and down, during the operation of loader, the fork will be affected by external force, so that the fork is easy to move up and down, and the stability is poor.

[0012] Through the above technical scheme, the utility model has at least the following technical effects or advantages:

[0013] 1. Since the fastening bolt and the universal bolt are used in cooperation, and the lower end of the universal bolt can be tightly contacted with the inner wall of the spade, the up-and-down movement of the fork body is effectively avoided, and the stability of the fork body during use is improved.

[0014] 2. Since the upper end of the hinge bolt has a through hole, when a larger torque is required to tighten it, a pry bar can be inserted into the through hole to easily tighten the hinge bolt using the lever principle, ensuring that its lower end is pressed against the inner wall of the bucket, thereby preventing the fork from moving up and down.

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0023] This utility model provides a simplified forklift, aiming to solve the problem of poor stability of existing forklifts during use. Figures 3 to 5 As shown, it includes two forks 1. Each fork 1 has a U-shaped connecting part at its rear end, which includes an upper plate 7 and a lower plate 8. Thus, the bottom plate of the bucket can be inserted between the upper plate 7 and the lower plate 8, thereby fixing the fork 1 to the bucket.

[0024] The U-shaped connecting part is fixed with the bucket 6 through connecting pieces. The connecting pieces include fastening bolts 2, articulated bolts 3 and gaskets 5. The fastening bolts 2 can pass through the U-shaped connecting part and the bucket 5 from bottom to top. Specifically, when the fork body 1 is assembled with the bucket 6, the fastening bolts 2 pass through the gaskets 5, the lower layer plate 8, the blade plate of the bucket 6 and the upper layer plate 7 from bottom to top in sequence, and finally are screwed with the nuts 4. Among them, the setting of the gaskets 5 can effectively prevent the loosening of the fastening bolts 2, and enhance the reliability of the connection. When the fork body is connected with the bucket, the nut 4 is installed at the upper end, which makes it more convenient to tighten the nut 4 in actual operation, and the fastening can be completed without additional tools or complex operation.

[0025] The articulated bolt 3 is threadedly installed on the U-shaped connecting part. Specifically, the upper layer plate of the U-shaped connecting part is provided with a threaded hole for installing the articulated bolt 3, and the articulated bolt 3 is installed in the threaded hole from top to bottom. During installation, by tightening the articulated bolt 3, the lower end thereof can press the inner wall of the bucket 6, thereby effectively avoiding the up-and-down movement of the fork body during use, and improving the stability of the fork body. In addition, the upper end of the articulated bolt 3 is provided with a through hole, so that when a larger torque is required for tightening, a crowbar can be inserted at the through hole to easily tighten the articulated bolt 3 by the leverage of the crowbar, thereby ensuring the pressing effect of the articulated bolt 3 on the inner wall of the bucket.

[0026] Further, the fastening bolts 2 of the U-shaped connecting part are provided with two, and the spacing of the two fastening bolts 2 is consistent with the spacing of the two tooth tip fixing holes on the bucket 6. Therefore, during installation, the tooth tip fixing holes on the bucket 6 can be used to fix the fork body, which is simple and convenient to operate, and does not require additional drilling or processing, thereby saving installation time and cost. At the same time, since the tooth tip fixing holes at the front end of the bucket 6 are usually provided with multiple rows, in actual use, the tooth tip fixing holes at different positions can be flexibly selected to fix the fork body 1 according to the size of the goods, so as to adjust the spacing between the two fork bodies 1, thereby adapting to the loading and unloading requirements of goods of different sizes. This adjustability makes the simple cargo fork of the utility model have strong adaptability, and can meet the requirements of various working conditions.

[0027] In actual use, as shown in Figure 4 and Figure 5 , the two fork bodies 1 are installed on the bucket 6 of the loader through the U-shaped connecting parts at the rear ends thereof, and are fixed by the fastening bolts 2 and the articulated bolts 3. After installation is completed, the front ends of the fork bodies 1 protrude outside the bucket 6, and are used for forking regular stone blocks, square boxes and other special goods. Since the above connection mode and structural design are adopted, the simple cargo fork of the utility model has good stability during use, can effectively avoid damage to the goods due to the shaking of the fork body during loading and unloading, and improves the work efficiency and safety.
