Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically a highly stable lifting forklift. Background Technology

[0002] Forklifts are mainly used for material transfer in factories, construction sites, and other similar settings. They play an irreplaceable role in modern logistics, warehousing, and manufacturing through horizontal handling, stacking, loading, unloading, and picking. When picking up materials, the forklifts lift and transfer them by inserting them into the racks at the bottom of the material. However, because the bottom of the material needs to be supported by the racks for insertion, the material is prone to instability and swaying during the transfer process after the forks are inserted. This can cause the racks to sway and fall, affecting the stability of picking up and transferring materials. Furthermore, since the forks are inserted horizontally from the bottom of the racks, they only support the bottom of the racks when lifting. Some materials cannot be transferred at an angle and can only be transferred horizontally. Horizontal transfer only supports the bottom of the racks, which can easily cause the racks to become unstable and slip during the transfer. Summary of the Invention

[0003] This invention provides a highly stable lifting forklift that overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A highly stable lifting forklift includes a cab, a fork carriage assembly, a lifting platform, a hydraulic unit, and a frame. The fork carriage assembly is mounted on the side of the lifting platform, the cab is mounted on the upper end of the frame, the hydraulic unit is controlled by electrical signals from the cab, and hydraulically extends and retracts at the front end of the frame. The output end of the hydraulic unit is connected to the side of the lifting platform and pushes the lifting platform to rotate at the front end of the frame.

[0006] The fork assembly includes a load-bearing mechanism, a support plate, an assembly panel, and a movable groove. The lower end of the assembly panel is provided with a bent support plate. An inclined movable groove is provided between the lower end of the load-bearing mechanism and the support plate. The stationary load-bearing mechanism and the left end surface of the support plate are at the same level. The load-bearing mechanism presses along the inclined direction of the movable groove, and the material slides at an incline on the surface of the load-bearing mechanism before abutting against the side of the assembly panel.

[0007] The load-bearing mechanism includes a connecting plate, a load-bearing plate, a sponge strip, and a first spring. The sponge strip is filled into the movable groove along the left side of the load-bearing plate. The side of the load-bearing plate is connected to the lower end of the connecting plate, and the lower end of the connecting plate is inclinedly provided with a first spring connected to the surface of the support plate. The load-bearing plate tilts along the movable groove, causing the connecting plate to squeeze the first spring, and causing the load-bearing plate to tilt and move along the movable groove through the first spring and sink elastically.

[0008] A preferred technical solution: The load-bearing plate is provided with a filler strip, a second spring, a rotating plate and a round shaft. The round shaft on the side of the rotating plate is movably connected to the lower end of the connecting plate, and the round shaft is above the second spring on the right side. There are two second springs, which are inclinedly arranged at the lower end of the rotating plate and the upper end of the support plate. The filler strip is attached to the surface of the rotating plate. The surface of the rotating plate is "V" shaped. When the right end of the "V" shape of the rotating plate is pressed to the right, the elastic bending of the second spring drives the "V" shape of the rotating plate to be pressed upward.

[0009] Compared with existing technologies, this technical solution has the following advantages:

[0010] In this invention, the support plate tilts and moves under the weight of the material through the space of the movable groove. At this time, the support plate drives the connecting plate to squeeze the first spring, causing the support plate to move and sink to the lower right. Then, the assembly panel and the support mechanism form an angle of less than 90°. This angle causes the material to tilt and slide. The assembly panel, the support mechanism, and the material form a triangular support, which improves the stability of the material's center of gravity. After the material tilts and slides on the surface of the support plate, the support plate sinks and its left end is lower than the horizontal position of the left end surface of the support plate. At this time, the material tilts on the surface of the support plate and abuts against the side of the assembly panel. The height difference formed by the left end surfaces of the support plate and the support plate prevents the material from sliding on the surface of the support plate to the left end surface of the support plate, preventing the material from easily sliding and detaching during the transfer process. This avoids the instability of only being able to transfer horizontally when the material is inconvenient to rotate. The material tilts and slides and abuts against the support, thereby enhancing the stability when transferring the material horizontally.

[0011] In this invention, the weight of the material presses down on the right end of the "V" shape of the rotating plate. When the material sways to the right, it squeezes the right end of the "V" shape of the rotating plate, causing the rotating plate to rotate elastically clockwise around the circular axis through the support of the second spring and the first spring at the right end. This causes the left end of the "V" shape of the rotating plate to squeeze upward. This upward squeezing force blocks the force of the material swaying to the right. In addition, the two symmetrical load-bearing mechanisms block the force of swaying left and right, thus preventing the material from swaying and improving the stability of the transferred material.

Detailed Implementation

[0018] like Figures 1 to 4 As shown, this utility model proposes a highly stable lifting forklift, including a cab 1, a fork assembly 2, a lifting plate 3, a hydraulic unit 4, and a frame 5. The fork assembly 2 is installed on the side of the lifting plate 3, the cab 1 is installed on the upper end of the frame 5, the hydraulic unit 4 is controlled by electrical signals from the cab 1, and the hydraulic unit 4 is hydraulically extended and retracted at the front end of the frame 5. The output end of the hydraulic unit 4 is connected to the side of the lifting plate 3, and pushes the lifting plate 3 to rotate and move at the front end of the frame 5.

[0019] The fork assembly 2 is provided with a load-bearing mechanism 21, a support plate 22, an assembly panel 23, and a movable groove 24. The lower end of the assembly panel 23 is provided with a bent support plate 22. An inclined movable groove 24 is provided between the lower end of the load-bearing mechanism 21 and the support plate 22. The left end surfaces of the stationary load-bearing mechanism 21 and the support plate 22 are at the same level. The load-bearing mechanism 21 presses along the inclined direction of the movable groove 24, and the material slides at an incline on the surface of the load-bearing mechanism 21 and then abuts against the side of the assembly panel 23.

[0020] Furthermore, the lower end of the assembly panel 23 is provided with two support plates 22, which are inserted parallel to each other below the material, and the load-bearing mechanism 21 and movable groove 24 on the surface of the two support plates 22 are symmetrically distributed.

[0021] Furthermore, the inclined angle of the movable groove 24 is 5°, and the lifting plate 3 is equipped with a chain lifting device. The chain is driven to rotate by a motor, thereby raising and lowering the fork assembly 2 fixed on the chain. When the hydraulic device 4 is hydraulically extended and retracted by the control cab 1, the output end of the hydraulic device 4 is connected to the side of the lifting plate 3, which will cause the lifting plate 3 to be hydraulically pushed, thereby causing the lifting plate 3 to rotate at the front end of the frame 5. This allows some material to be inserted and removed, causing the lifting plate 3 to drive the fork assembly 2 to rotate, thereby rotating the material and forming a triangular angle to stabilize the center of gravity of the material. The fork assembly 2 can be tilted and inserted into the bottom of the material at a lower position for transfer. After the material is inserted horizontally, the support plate 22 supports the bottom of the material. The weight of the material will cause the support mechanism 21 to tilt and move along the movable groove 24. At this time, the support mechanism 21 is in a sinking and tilting state, which causes the material to slide along the support mechanism 21 and abut against the side of the assembly panel 23, thereby forming an "L"-shaped support for the side and bottom of the material to prevent the material from shaking after insertion and transfer.

[0022] The load-bearing mechanism 21 includes a connecting plate 211, a load-bearing plate 212, a sponge strip 213, and a first spring 214. The sponge strip 213 fills the movable groove 24 along the left side of the load-bearing plate 212. The lower end of the connecting plate 211 is connected to the side of the load-bearing plate 212, and the lower end of the connecting plate 211 is inclinedly provided with the first spring 214 connected to the surface of the support plate 22. The load-bearing plate 212 tilts along the movable groove 24, causing the connecting plate 211 to squeeze the first spring 214, and causing the load-bearing plate 212 to tilt and move along the movable groove 24 through the first spring 214 and elastically sink.

[0023] Furthermore, when the first spring 214 is stationary, the load-bearing plate 212 is in a horizontal state. In this invention, the load-bearing plate 212 tilts and moves under the weight of the material through the space of the movable groove 24. At this time, the load-bearing plate 212 drives the connecting plate 211 to squeeze the first spring 214, and causes the load-bearing plate 212 to move and sink to the lower right. Then, the assembly panel 23 and the load-bearing mechanism 21 form an angle of less than 90°. This angle will cause the material to tilt and slide. The assembly panel 23, the load-bearing mechanism 21 and the material form a triangular support, which improves the stability of the material's center of gravity. The material is supported by the load-bearing plate 21. 2. After the surface tilts and slides, the support plate 212 sinks and its left end is lower than the horizontal position of the left end surface of the support plate 22. At this time, the material tilts on the surface of the support plate 212 and abuts against the side of the assembly panel 23. Through the height difference formed by the support plate 212 and the left end surface of the support plate 22, the material will not slide on the surface of the support plate 212 towards the left end surface of the support plate 22, preventing the material from easily sliding and falling off during the transfer process. This avoids the instability of only being able to transfer horizontally when the material is inconvenient to rotate, and allows the material to tilt and slide against the support to enhance the stability when transferring the material horizontally.

[0024] The load-bearing plate 212 is provided with a filler strip 2121, a second spring 2122, a rotating plate 2123 and a round shaft 2124. The round shaft 2124 on the side of the rotating plate 2123 is movably connected to the lower end of the connecting plate 211, and the round shaft 2124 is above the second spring 2122 on the right side. There are two second springs 2122, which are inclinedly arranged at the lower end of the rotating plate 2123 and the upper end of the support plate 22. The filler strip 2121 is attached to the surface of the rotating plate 2123. The surface of the rotating plate 2123 is V-shaped. When the right end of the V-shape of the rotating plate 2123 is pressed to the right, the elastic bending of the second spring 2122 drives the V-shape of the rotating plate 2123 to be pressed upward.

[0025] Furthermore, the rotating plate 2123 is movably connected to and rotates at the lower end of the connecting plate 211 via the round shaft 2124 on its side. When the rotating plate 2123 rotates, the load-bearing plate 212 and the connecting plate 211 are in a sunken state. The rotation of the rotating plate 2123 will cause the connecting plate 211 to rotate. After the connecting plate 211 rotates, it will be blocked after slight rotation due to the limited gap between it and the lower side of the assembly panel 23. Thus, the rotating plate 2123 is elastically supported in the movable groove 24 by the first spring 214 at the lower end of the connecting plate 211. The position creates a 5° rotation space, and then the rotating plate 2123 rotates under the support of the second spring 2122 and the first spring 214 on the right side via its side circular shaft 2124. When the two second springs 2122 are installed at an angle, the second spring 2122 on the left end is longer. When stationary, the right end of the "V" shape of the rotating plate 2123 is higher, and the filling strip 2121 is made of sponge material. When the material slides on the surface of the load-bearing plate 212, it slides along the "V" shape on the left and right ends of the rotating plate 2123 on the surface of the filling strip 2121.

[0026] In this invention, the weight of the material presses down on the right end of the "V" shape of the rotating plate 2123. When the material sways to the right, it squeezes the right end of the "V" shape of the rotating plate 2123, causing the rotating plate 2123 to rotate clockwise elastically around the circular shaft 2124 with the support of the second spring 2122 and the first spring 214 at the right end. This causes the left end of the "V" shape of the rotating plate 2123 to be squeezed upward. This upward squeezing force blocks the force of the material swaying to the right. Then, the two symmetrical load-bearing mechanisms 21 block the force of swaying left and right, thus preventing the material from swaying and improving the stability of the transferred material.

[0027] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
