Description

Technical Field

[0001] The utility model relates to the technical field of pallet forks, in particular to a pallet fork which can extend longitudinally and is used to guard a shelf. Background Art

[0002] Pallet forks are forklift attachments specially designed for picking up and transporting pallets. They can adjust the fork spacing through hydraulic or mechanical means to adapt to pallets of different sizes and specifications, achieving efficient and stable handling operations. Pallet forks are widely used in logistics, warehousing, manufacturing and other fields. They are one of the indispensable tools for modern material handling. However, existing pallet forks still have certain defects when used.

[0003] In the prior art, pallet forks are an important accessory of forklifts, which are mainly used to transport and stack goods on pallets. Pallet forks are usually installed on forklifts. Pallet forks can lift and transport two stacked pallets. Since the height of the two groups of pallets stacked together is determined by the height of the stacked goods, and the backrest on the pallet fork is usually integrated with the fork, it is difficult for the backrest to extend longitudinally. Once the backrest cannot block the upper pallet, the upper pallet will be prone to shaking and position displacement when following the movement of the pallet fork, which poses certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to provide a pallet fork with a longitudinally extendable backrest, so as to solve the problem in the background art that the backrest on the pallet fork currently on the market is difficult to extend longitudinally.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pallet fork that can extend the longitudinal direction of the backrest, comprising: a frame, a side shift oil cylinder and a limit block, the back of the frame is installed with a side shift oil cylinder, the top of the frame is installed with a limit block, a round rod is installed at the front of the frame, the outer side of the round rod is slidably connected to the fork seat, the inside of the frame is slidably connected with a slide rod, the front of the slide rod is installed with a fork body, the top of the fork body is connected to the backrest body, the inner side of the frame is respectively installed with a distance adjustment cylinder and a spring cylinder, the top of the fork body is provided with a slide groove, the inner wall of the slide groove is welded with a block, the outer side of the fork body is threadedly connected with a threaded knob, the inner side of the backrest body is provided with a limit groove near the block, and the inner side of the backrest body is provided with a threaded hole near the threaded knob.

[0006] Preferably, the threaded holes are distributed at equal intervals inside the shelf backstop body.

[0007] Preferably, a sliding structure is formed between the stop block and the shelf body via a limiting groove.

[0008] Preferably, a connecting block is welded below the end of the fork body, and a guide column is slidably connected inside the connecting block.

[0009] Preferably, one end of the guide column is connected to a baffle, and the other end of the guide column is connected to a connecting plate.

[0010] Preferably, a compression spring is connected between the connecting plate and the connecting block, and a rubber plate is bonded to the front of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the pallet fork of the shelf guard can be extended longitudinally, and when the shelf guard body moves, it can slide with the fork body through the slide groove; when a group of threaded holes on the shelf guard body move to the end position of the threaded knob, the threaded knob can be tightened so that the end of the threaded knob can slide into the interior of the shelf guard body through the threaded hole; when the compression spring is squeezed to the maximum extent, one side of the connecting plate can contact the end of the fork body and the surface of the connecting block; through the compression buffering method of the compression spring and the rubber plate, the end of the fork body can greatly reduce the force of squeezing and colliding with the pallet surface, so that the fork body is not easy to damage the pallet, and the end of the fork body can be protected at the same time.

[0012] 1. As one of the important attachments of forklifts, pallet forks play an important role in material handling. The main body of the backstop on the traditional pallet fork is difficult to extend longitudinally. Once the upper pallet cannot lean on the main body of the backstop, it is easy for the upper pallet to shake and shift in position, which poses certain safety hazards. When the main body of the backstop moves, it can slide with the fork body through the slide groove. When a group of threaded holes on the main body of the backstop moves to the end position of the threaded knob, the threaded knob can be tightened so that the end of the threaded knob can slide into the interior of the backstop through the threaded hole, thereby The rack body is fixed so that the upper pallet can lean against the surface of the rack body during movement, thereby improving the stability and safety of transporting the upper and lower pallets. When the fork body moves, it can drive the fork seat and the slide bar to move. When the fork seat moves, it can slide through the round rod, and when the slide bar moves, it can slide with the frame, so as to adjust the spacing between the six sets of fork bodies. At this time, the six sets of fork bodies can be unfolded and fork-transport three groups of one-layer or three groups of two-layer pallets. Up to three adjacent pallets can be forked at the same time by the six sets of fork bodies, so that the goods can be transported efficiently.

[0013] 2. The pallet fork can lift the pallet through the fork body, so that the goods on the pallet can be transported. During the use of the fork body, it is inevitable that the fork body cannot be accurately inserted into the inside of the pallet at one time, which will cause the end of the fork body to squeeze and collide with the surface of the pallet, making the surface of the pallet easily damaged. When the end of the fork body cannot be accurately inserted into the inside of the pallet at one time, the surface of the rubber plate will collide with the surface of the pallet, causing the rubber plate to be squeezed and deformed, and produce a buffering effect. At the same time, the rubber plate can drive the connecting plate to move toward the direction of the connecting block. When the connecting plate moves, it can drive the guide column and the baffle to move. When the compression spring is squeezed to the maximum extent, one side of the connecting plate can contact with the end of the fork body and the surface of the connecting block. Through the compression buffering method of the compression spring and the rubber plate, the end of the fork body can greatly reduce the force of the squeezing and collision on the pallet surface, making it difficult for the fork body to damage the pallet and at the same time protecting the end of the fork body.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 3 It can be seen that the utility model provides a technical solution: a pallet fork with a longitudinally extendable backrest, comprising: a frame 1, a side shift cylinder 2 and a limit block 3, a side shift cylinder 2 is installed on the back of the frame 1, a limit block 3 is installed on the top of the frame 1, a round rod 4 is installed on the front of the frame 1, a fork seat 5 is slidably connected to the outside of the round rod 4, a slide rod 6 is slidably connected to the inside of the frame 1, a fork body 7 is installed in front of the slide rod 6, a fork body 7 is connected to the top of the fork body 7 with a backrest body 8, and the inner sides of the frame 1 are respectively A distance-adjusting oil cylinder 9 and a spring cylinder 10 are installed. A slide groove 11 is provided on the top of the fork body 7. A stopper 12 is welded to the inner wall of the slide groove 11. A threaded knob 13 is threadedly connected to the outer side of the fork body 7. A limiting groove 14 is provided inside the shelf block body 8 near the stopper 12. A threaded hole 15 is provided inside the shelf block body 8 near the threaded knob 13. The threaded holes 15 are evenly spaced inside the shelf block body 8. A sliding structure is formed between the stopper 12 and the shelf block body 8 through the limiting groove 14.

[0022] During specific implementation, as one of the important accessories of a forklift, the pallet fork plays an important role in material handling. The backrest body 8 on the traditional pallet fork is difficult to extend longitudinally. Once the upper pallet cannot lean on the backrest body 8, the upper pallet is prone to shaking and position displacement, which poses a certain safety hazard. The backrest body 8 can be pulled upward. When the backrest body 8 moves, it can slide with the fork body 7 through the slide groove 11. At the same time, the backrest body 8 slides, and can slide with the block 12 through the limit groove 14. When a group of threaded holes 15 on the backrest body 8 moves to the end position of the threaded knob 13, the threaded knob 13 can be tightened so that the end of the threaded knob 13 can be threadedly slid into the inside of the backrest body 8 through the threaded hole 15. , thereby fixing the shelf backstop body 8. At this time, the extended height of the shelf backstop body 8 can block the outer side of the upper pallet, so that the upper pallet can lean against the surface of the shelf backstop body 8 during the movement, so that the upper pallet is not easy to shake and shift in position, thereby improving the stability and safety of transporting the upper and lower pallets. At the same time, when the distance adjustment cylinder 9 and the spring cylinder 10 are in operation, they can drive the outer fork body 7 to move. When the fork body 7 moves, it can drive the fork seat 5 and the slide bar 6 to move. When the fork seat 5 moves, it can slide through the round rod 4. When the slide bar 6 moves, it can slide with the frame 1, thereby adjusting the spacing between the six groups of fork bodies 7. At this time, the six groups of fork bodies 7 can be unfolded and fork-transport three groups of one-layer or three groups of two-layer pallets.

[0023] See Figure 1-Figure 3 It can be seen that, by using six sets of fork bodies 7, up to three adjacent pallets can be forked at the same time, thereby efficiently transporting goods.

[0024] See Figure 1 、 Figure 2 、 Figure 4 and Figure 5 It can be seen that a connecting block 16 is welded to the lower end of the fork body 7, and a guide column 17 is slidably connected to the inside of the connecting block 16. One end of the guide column 17 is connected to a baffle 18, and the other end of the guide column 17 is connected to a connecting plate 19. A compression spring 20 is connected between the connecting plate 19 and the connecting block 16, and a rubber plate 21 is bonded to the front of the connecting plate 19. The material of the connecting plate 19 is iron.

[0025] During specific implementation, the pallet fork can lift the pallet through the fork body 7, so that the goods on the pallet can be transported. Since the fork body 7 is usually made of high-strength steel, and the pallet is usually made of wood or plastic, it is inevitable that the fork body 7 cannot be accurately inserted into the interior of the pallet at one time during use, which will cause the end of the fork body 7 to squeeze and collide with the surface of the pallet, making the surface of the pallet easily damaged. When the fork body 7 moves, it can drive the connecting plate 19 and the rubber plate 21 to move. When the end of the fork body 7 cannot be accurately inserted into the interior of the pallet at one time, the surface of the rubber plate 21 will collide with the surface of the pallet, causing the rubber plate 21 to be squeezed and deformed, and produce a buffering effect. At the same time, the rubber plate 21 can drive the connecting plate 19 to move in the direction of the connecting block 16. When the connecting plate 19 moves, it can drive the guide column 17 and the baffle 18 to move, and when the connecting plate 19 moves, it can compress the compression spring 20. When the compression spring 20 is squeezed to the maximum extent, one side of the connecting plate 19 can contact the end of the fork body 7 and the surface of the connecting block 16.

[0026] See Figure 1 、 Figure 2 、 Figure 4 and Figure 5 It can be seen that by means of compression buffering by the compression spring 20 and the rubber plate 21, the end of the fork body 7 can greatly reduce the force of squeezing and colliding with the surface of the pallet, making it less likely for the fork body 7 to cause damage to the pallet, and at the same time protecting the end of the fork body 7.

[0027] When the pallet fork 7 is lifted up, the fork body 7 can be lifted up and the pallet fork 7 can be lifted up by the fork body 7.
