[0001] The utility model relates to the technical field of forklifts, in particular to a fork tine protection component of a forklift. Background Art

[0002] Industrial handling vehicles are widely used in ports, stations, airports, freight yards, factory workshops, warehouses, circulation centers and distribution centers, etc. They are used to load, unload and carry pallet cargo in cabins, carriages and containers. They are indispensable equipment in pallet transportation and container transportation. Forklifts play a very important role in the logistics system of enterprises and are the main force in material handling equipment. They are widely used in various sectors of the national economy such as stations, ports, airports, factories, warehouses, etc. During the Second World War, forklifts were developed. China began to manufacture forklifts in the early 1950s. Especially with the rapid development of China's economy, the material handling of most enterprises has been separated from the original manual handling, and replaced by mechanized handling mainly based on forklifts. Therefore, in the past few years, the demand for China's forklift market has grown at a double-digit rate every year.

[0003] With the increase in steel operations, under the premise of pursuing safety and efficiency, forklifts have highlighted their importance in the slab operation process. However, there are also disadvantages in the operation. During the use of the forklift, the fork tine suspension part is weak and can only withstand pulling force but not bending force. This causes the fork tine suspension part to be broken as the fork tine tilts up, and the fork tine itself will undergo stress changes after the load time is too long, thereby reducing the load capacity of the fork tine itself and causing the fork tine to break. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and to provide a forklift fork protection component which can prolong the service life of the fork tines, reduce the probability of them being broken, and prevent the fork tine hanging part from breaking due to being unable to withstand the bending force, thereby causing an operation accident.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In order to prevent the load capacity of the fork tines from decreasing, which would cause the fork tines to be overloaded and break, a further preferred technical solution is that the reinforcement device includes a frame, a plurality of plug plates are evenly spaced on the frame, a through slot is opened in the middle of the plurality of plug plates, the cross bar passes through the through slot and is connected to both ends of the frame, the cross bar is adapted to the through slot, a connecting plate for being hinged to the cylinder push rod is provided at the bottom of the frame, and the cross-sectional area of ​​the connecting plate gradually decreases along the extension direction of the fork tine.

[0008] In order to reduce the pressure and impact of the load on the fork tines, thereby reducing the load on the fork tines, a further preferred technical solution is that the buffer device includes a buffer plate, a plurality of grooves are evenly spaced on the buffer plate, and a buffer component is provided in each of the plurality of grooves. The buffer component includes a buffer head and a spring connected to the buffer head, and the other end of the spring is connected to the groove.

[0009] In order to prevent the edges of the buffer heads on the buffer assembly from scratching the load and damaging the object during the loading process of the fork tines, a further preferred technical solution is that the buffer heads are hemispherical.

[0010] In order to prevent the fork tine hanging cloth from breaking as the fork tine tilts due to being unable to withstand the bending force, a further preferred technical solution is that at least one clamp connected to the lifting part is sleeved on the fork tine hanging part.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a mesh reinforcement plate and a connecting plate with a gradually decreasing height at the bottom of the fork tine, thereby dispersing the stress on the fork tine, and at the same time hinges the cylinder push rod at the lifting component and the reinforcement plate. When the fork tine is raised, a triangular support is formed with the lifting component.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0016] like Figure 1-Figure 2 As shown, a forklift fork tine protection assembly includes a fork tine 1, one end of the fork tine 1 is vertically connected to a fork tine hanging part 2 for fixing to a lifting part 3, the top of the lifting part 3 is connected to the lifting assembly, and the lifting part 3 can slide up and down. The lifting assembly here is a common lifting assembly of a forklift and no unnecessary details are given. In order to realize the lifting and lowering of the fork tine 1, a reinforcement device 5 is provided at the bottom of the fork tine 1, and the reinforcement device 5 is hinged with a cylinder push rod, and the push rod 4 of the cylinder push rod is hinged to the reinforcement device 5, and the cylinder 16 of the cylinder push rod is hinged to the frame 15 of the forklift, so that it is convenient to form a triangular support with the fork tine 1 after the fork tine 1 is lifted. When the fork tine 1 is lowered to the lowest point, the push rod 4 is horizontal with the fork tine 1, and does not affect the fork tine 1 from lifting objects. The control of the cylinder is integrated with the lifting part. As the lifting part rises and falls, the cylinder controls the push rod to extend and retract, and a buffer device 6 is provided on the upper part of the fork tine 1.

[0017] Specifically, in order to prevent the load capacity of the fork tines from decreasing and causing the fork tines to be overloaded and break, a further preferred technical solution is that the reinforcement device 5 includes a frame 7, and a plurality of plug plates 8 are arranged at equal intervals on the frame 7. A through slot 9 is opened in the middle of the plurality of plug plates 8. A cross bar 10 passes through the through slot 9 and is connected to both ends of the frame 7. The cross bar 10 is adapted to the through slot 9. A connecting plate 17 for being hinged to the push rod 4 is provided at the bottom of the frame 7. In some other embodiments, the cross-sectional area of ​​the connecting plate 17 gradually decreases along the extension direction of the fork tines. It is now larger on the left and smaller on the right. The purpose of this setting is to improve the bearing capacity of the fork teeth themselves. When the forklift does not need to be placed at the bottom, the cylinder push rod can be removed to avoid the protruding part of the connecting plate from damaging the cylinder push rod. When the forklift needs to be placed at the bottom, a horizontal connecting plate can be used, and only the cylinder push rod can be used to complete the support. Of course, the two can also be set at the same time to provide maximum support for the fork teeth themselves. The mesh structure formed by the cross bar and the plug plate can effectively disperse the stress on the fork teeth, thereby increasing the service life of the fork teeth and making them less likely to break.

[0018] Specifically, in order to reduce the pressure and impact of the load on the fork tines, thereby reducing the load on the fork tines, a further preferred technical solution is that the buffer device 6 includes a buffer plate, and a plurality of grooves 13 are evenly spaced on the buffer plate. A buffer assembly is provided in each of the plurality of grooves 13, and the buffer assembly includes a buffer head 11 and a spring 12 connected to the buffer head 11, and the other end of the spring 12 is connected to the groove 13. The spring on the buffer assembly will give the load an elastic force, thereby offsetting a part of the gravity of the load on the fork tines, so as to extend the service life of the fork tines, and also prevent the load from wearing the surface of the fork tines. Specifically, in order to prevent the edge of the buffer head on the buffer assembly from scratching the load during the loading process of the fork tines, thereby damaging the object, a further preferred technical solution is that the buffer head 11 is hemispherical.

[0019] Specifically, in order to prevent the fork tine suspension part from breaking due to the tilting of the fork tine due to being unable to withstand the bending force, a further preferred technical solution is that at least one clamp 14 connected to the lifting part 3 is provided on the fork tine suspension part 2, and the clamp here is also connected to the lifting part, and is lifted and lowered together with the fork tine suspension part, so as to provide support for the fork tine suspension part 2 that is tilted due to the tilting of the fork tine, thereby improving its ability to withstand bending force. In addition, the utility model comprises two forks and a fork tine suspension part adapted thereto, and the two fork tine suspension parts are connected in the middle by a connecting rod, which is the same as a conventional forklift. Therefore, since at least two clamps are provided on the forklift, a clamp 14 is provided for each fork tine suspension part.

[0020] The utility model provides a mesh reinforcement plate and a connecting plate with a gradually decreasing height at the bottom of the fork tine, thereby dispersing the stress on the fork tine, and at the same time hinges the cylinder push rod at the lifting component and the reinforcement plate. When the fork tine is raised, a triangular support is formed with the lifting component. Firstly, it can provide another supporting force for the fork tine to improve the load capacity of the fork tine, and secondly, it can improve the ability of the fork tine suspension to withstand bending force, so that it is not easy to be broken; in addition, a buffer component is provided on the fork tine, thereby providing an upward elastic force to the load on the fork tine, reducing the pressure received by the fork tine itself; the three devices work together to increase the load capacity of the fork tine, and solve the problem of breakage caused by the reduction of the load capacity of the fork tine; the setting of the clamp and the synergistic effect of the cylinder push rod enable the fork tine suspension to withstand a certain intensity of bending force, thus avoiding the breakage of the fork tine suspension, thereby generally improving the service life of the forklift and reducing the maintenance and replacement costs of the forklift.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
