Description

Technical Field

[0001] This invention relates to the field of transportation technology, and more specifically to a forklift work frame for handling large metal material plates. Background Technology

[0002] Forklifts are a common tool vehicle in industrial transportation processes. They are widely used for their advantages of strong short-distance transportation capacity, large load capacity, and flexible operation even in narrow areas. The forklift work frame is the tool frame at the front of the forklift used to support the load.

[0003] Existing forklift frames lack the ability to adjust the load posture of goods. For example, the load transported by forklifts is relatively heavy. Taking a large metal plate as an example, the forklift frame cannot adjust the posture and position of the metal plate, causing it to lie flat on the forklift frame with the center of gravity relatively forward. This makes it quite likely that the forklift will tilt forward or even tip over when moving, which poses a certain degree of danger. However, if the metal plate can be actively adjusted after being lifted to shift its center of gravity backward, the stability and safety during transportation can be improved.

[0004] To address the aforementioned problems, this invention proposes a forklift work frame for handling large metal material plates. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a forklift work frame for handling large metal material plates, so as to solve the above-mentioned technical problems.

[0007] Technical solution

[0008] To achieve the objectives of this invention, the technical solution adopted is as follows:

[0009] A forklift work frame for handling large metal plates includes a forklift frame and a movable seat disposed below the forklift frame. The movable seat has a rectangular inner cavity with a slide rail installed at the bottom of the cavity. Slider blocks are slidably mounted at both ends of the slide rail. A first frame and a second frame are respectively hinged to the two sliders, and one end of the first frame and the second frame are hinged to each other. Rollers are coaxially mounted at the hinge of the first frame and the second frame. A hydraulic cylinder is installed at the tail end of the movable seat. The output end of the hydraulic cylinder is fixedly connected to a slider located at the tail end of the inner cavity of the movable seat. A first locking frame and a second locking frame are respectively fixedly connected to the inner sides of the two sliders. The first locking frame and the second locking frame engage when they come into contact with each other.

[0010] Furthermore, a vertical groove is provided on the side of the forklift frame, and a bracket is slidably installed on the inner side of the groove. The bottom end of the bracket contacts the surface of the forklift frame, and a spring buckle is provided on the forklift frame to limit the bottom end of the bracket.

[0011] Furthermore, the spring buckle includes a locking pin that is movably fitted into the inner hole of the forklift frame. A third magnet is fixedly connected to the bottom end of the locking pin. A spring is also fitted into the inner hole of the forklift frame, and the top of the spring is elastically supported by the locking pin. The third magnet extends downward through the forklift frame to the outside.

[0012] Furthermore, a fourth magnet is fixedly installed on the outer side of the movable seat. The fourth magnet is located directly below the third magnet. The fourth magnet and the third magnet are opposite poles that attract each other. The attraction between the fourth magnet and the third magnet is greater than the elastic force of the spring.

[0013] Furthermore, the bottom of the bracket is provided with a step that cooperates with the locking post for limiting movement;

[0014] When the bracket contacts the forklift frame and forms its maximum angle with the vertical portion of the forklift frame, the step is also in a vertical state and abuts against the vertical surface of the locking post.

[0015] Furthermore, a second magnet is provided on the slider near the first end of the rectangular inner cavity of the movable seat, and a first magnet is fixedly installed on the inner wall of the first end of the rectangular inner cavity of the movable seat. The second magnet and the first magnet are attracted to each other by opposite poles.

[0016] Furthermore, the end of the first locking frame includes a locking mechanism consisting of a locking platform and a guide slide, and the end of the second locking frame includes a spring locking block. The spring locking block initially approaches the locking platform and first contacts the left inclined surface of the locking platform, and slides along the inclined surface to finally be aligned and enter the inner side of the locking platform.

[0017] Furthermore, when the spring block is located inside the latching platform and moves in the opposite direction to the guide slide, the spring block slides along the right inclined surface of the guide slide and eventually disengages from the inside of the latching platform.

[0018] Beneficial effects: The hydraulic cylinder pushes the slider to slide along the slide rail, while the tail slider moves along the slide rail, causing the first and second locking frames to approach each other and finally lock together. At this time, the first frame, the second frame, the upward bulge, the first locking frame, and the second locking frame can form a stable triangle, and the first frame is almost equal to the height of the triangle. The roller located at the hinge of the first and second frames presses against the bottom of the bottom plate and lifts the stack of plates, causing the plates to tilt backward as a whole. Then the hydraulic cylinder retracts and drives the triangle to move along the slide rail to the tail end. As a result, the roller presses against the plate to further increase the angle with the horizontal plane, causing its center of gravity to move further back, stabilizing the center of gravity position opening, and enhancing the stability and safety of transportation.

[0019] With the movable support at the bottom, the support prevents a stack of boards from moving too much towards the inside of the forklift frame when it is scooped up. The support's obstruction will keep the inner edge of the boards roughly at the bottom of the support, or its inner edge will be arranged diagonally along the support. This allows for a triangular redundancy area to support the upper part of the boards that slide down after being lifted by the rollers. This ensures that the upper boards also contact the plane of the forklift frame, rather than being supported on the vertical plane of the forklift frame. This makes it easier to almost straighten the stack of boards when the hydraulic cylinder pulls the arch, and further shift its center to the rear.

[0020] By setting up a latching platform, a guide slide, and a spring latch, the spring latch automatically latches into the latching platform when initially approaching. At this time, pulling the first latching frame can drive the second latching frame to move. Pushing the first latching frame can cause the spring latch to move in this direction, causing the spring latch to disengage from the latching position of the latching platform, thus separating the first and second latching frames. This achieves the automatic latching and disengaging actions of the first and second latching frames as they operate. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-7 The present invention is further illustrated by the embodiments:

[0031] like Figure 1 and Figure 2 As shown, a forklift work frame for handling large metal material plates includes a forklift frame 1 and a movable seat 2 disposed below the forklift frame 1. The movable seat 2 has a rectangular inner cavity and a slide rail 4 is installed at the bottom of the inner cavity. Slider 3 is slidably installed at both ends of the slide rail 4. A first frame 51 and a second frame 52 are respectively hinged to the two sliders 3, and one end of the first frame 51 and the second frame 52 are hinged to each other. A roller 6 is coaxially installed at the hinge of the first frame 51 and the second frame 52. The purpose of setting the roller 6 is to allow it to roll under pressure and reduce friction. A hydraulic cylinder 9 is installed at the tail end of the movable seat 2. The output end of the hydraulic cylinder 9 is fixedly connected to a slider 3 located at the tail end of the inner cavity of the movable seat 2. A first locking frame 7 and a second locking frame 8 are respectively fixedly connected to the inner sides of the two sliders 3. The first locking frame 7 and the second locking frame 8 are engaged after contacting each other.

[0032] After the forklift frame 1 scoops up the sheet metal, it moves down to the top of the moving seat 2. The hydraulic cylinder 9 pushes the slider 3 to slide along the slide rail 4. The first frame 51 and the second frame 52, which were originally in an angled state with the angle opening facing downwards, bulge up. At the same time, the slider 3 at the rear end moves along the slide rail 4, causing the first locking frame 7 and the second locking frame 8 to move closer to each other and finally lock together. At this time, the first frame 51, the second frame 52, the first locking frame 7 and the second locking frame 8 can form a stable triangle, similar to a right triangle, and the first frame 51 is almost equal to the height of the triangle. The roller 6 located at the hinge of the first frame 51 and the second frame 52 presses against the bottom of the bottom sheet metal and lifts the stack of sheet metal, causing the sheet metal to tilt backward as a whole. As the hydraulic cylinder 9 retracts, it drives the triangle to move along the slide rail 4 to the rear end. Then the roller 6 presses against the sheet metal to further increase the angle with the horizontal plane, causing its center of gravity to move further backward.

[0033] The above is one way of operating. Another way is to first shape the triangle, then lower the forklift frame 1. After the plate comes into contact with the roller 6, it will naturally be pushed and tilted, and the center of gravity will naturally be shifted backward. Then, the hydraulic cylinder 9 will be driven to pull it further to straighten the plate.

[0034] Furthermore, a vertical groove 101 is provided on the side of the forklift frame 1, and a bracket 10 is slidably installed on the inner side of the groove 101. The bottom end of the bracket 10 contacts the surface of the forklift frame 1, and a spring buckle 11 is provided on the forklift frame 1 to limit the bottom end of the bracket 10.

[0035] The purpose of setting up the bracket 10 is to prevent a stack of boards from moving excessively inwards towards the forklift frame 1 when it is initially lifted. The obstruction of the bracket 10 will cause the inner edge of the boards to be roughly located at the bottom of the bracket 10, or its inner edge will be arranged diagonally along the bracket 10. This allows for the provision of space for... Figure 2 The triangular redundant area formed by the middle support 10 and the forklift frame 1 is used to support the portion of the sliding plate that is lifted up by the roller 6. This allows the plate that is on top to also contact the plane of the forklift frame 1, instead of being supported on the vertical plane of the forklift frame 1. This makes it easier to almost straighten a stack of plates when the hydraulic cylinder 9 pulls the arch frame 5, and further move its center back.

[0036] Furthermore, the spring buckle 11 includes a locking post 111 movably sleeved in the inner hole of the forklift frame 1. The bottom end of the locking post 111 is fixedly connected to a third magnet 113. A spring 112 is also sleeved in the inner hole of the forklift frame 1, and the top of the spring 112 is elastically supported by the locking post 111. The third magnet 113 extends downward through the forklift frame 1 to the outside.

[0037] Due to the elastic force of the spring 112, the locking post 111 can be pushed out of the inner hole of the forklift frame 1 in the initial state. The locking post 111 can limit the bracket 10, and can block the bracket 10 so that the bracket 10 will not retract excessively inward even when the inclined surface is under pressure.

[0038] Furthermore, a fourth magnet 12 is fixedly installed on the outside of the movable base 2. The fourth magnet 12 is located directly below the third magnet 113. The fourth magnet 12 and the third magnet 113 are opposite poles that attract each other. The attraction between the fourth magnet 12 and the third magnet 113 is greater than the elastic force of the spring 112.

[0039] like Figure 4As shown, when the forklift frame 1 descends, it will eventually approach the fourth magnet 12 and remain at a certain distance from the top of the fourth magnet 12. The third magnet 113 will be pulled over by the attraction force, overcoming the elastic force of the spring 112. The locking pin 111 will then retract into the inner hole of the forklift frame 1, thereby causing the bracket 10 to lose its limiting constraint. Thus, the pressure acting on the outer inclined surface of the bracket 10 can directly press the bracket 10 inward and make the bracket 10 finally vertical. The original stacked plates and the state of being aligned with the inclined surface of the bracket 10 will be improved. They will move further downward due to the inward contraction of the bracket 10, so that the angle formed by the plate being lifted by the roller 6 and the horizontal plane can be further increased.

[0040] Furthermore, the bottom of the bracket 10 is provided with a step 1001 that cooperates with the locking post 111 for limiting the movement;

[0041] When the bracket 10 contacts the forklift frame 1 and forms the maximum angle with the vertical part of the forklift frame 1, the step 1001 is also in a vertical state and abuts against the vertical surface of the locking post 111.

[0042] like Figure 2 The image shows its initial state. The purpose of setting the step 1001 is that when the outer slope of the bracket 10 is subjected to force, the step 1001 at its bottom can provide an inward horizontal pressure to the locking post 111. If we assume that the step 1001 is not set here and only the inner slope is retained, then the part in contact with the inner slope should only be the top edge of the locking post 111. In this case, the force on the locking post 111 will be downward, which will press the locking post 111 downward and will not be able to form a good limiting effect on the bracket 10. However, the structure in this application will not be like this.

[0043] Furthermore, a second magnet 31 is provided on the slider 3 near the first end of the rectangular inner cavity of the movable seat 2, and a first magnet 21 is fixedly installed on the inner wall of the first end of the rectangular inner cavity of the movable seat 2. The second magnet 31 and the first magnet 21 are attracted to each other by opposite poles.

[0044] like Figure 5 As shown, the second magnet 31 and the first magnet 21 are initially in an attracted state. When the hydraulic cylinder 9 pushes the first frame 51 and the second frame 52 towards the head end of the rectangular inner cavity and the first engaging frame 7 and the second engaging frame 8 disengage, the second magnet 31 and the first magnet 21 will naturally attract together. At the same time, the second engaging frame 8 loses its pulling force. Then, the slider 3 will be completely constrained by the attractive force between the second magnet 31 and the first magnet 21. The acute angle at the apex of the triangle originally formed between the first frame 51 and the second frame 52 will also be gradually flattened and returned to normal. Figure 3 The initial state is shown.

[0045] Furthermore, the end of the first locking frame 7 includes a locking mechanism consisting of a locking platform 71 and a guide slide 72, and the end of the second locking frame 8 includes a spring locking block 81. The spring locking block 81 initially approaches the locking platform 71 and first contacts the left inclined surface of the locking platform 71, and slides along the inclined surface to finally be aligned and enter the inner side of the locking platform 71.

[0046] like Figure 7 As shown in the two figures above, from left to right, the process is as follows: the spring latch 81 moves up the left slope outside the latching platform 71 and eventually enters the inside of the latching platform 71. The latching platform 71 is concave in the front and pointed in the back. The relationship between the tip of the latching platform 71 and the undeflected spring latch 81 is as follows: the tip of the latching platform 71 is to the right of the center of the spring latch 81. Therefore, when the spring latch 81 moves towards the latching platform 71, it can move along the left side of the latching platform 71. When it passes the left side of the latching platform 71, the spring latch 81 will return to the center due to its own elasticity and re-enter the concave part of the latching platform 71. When the first latching frame 7 pulls the second latching frame 8, the spring latch 81 will be tightly latched on the inside of the latching platform 71, dragging the second latching frame 8 to move synchronously.

[0047] Furthermore, when the spring block 81 is located inside the latching platform 71 and moves in the opposite direction to the guide slide 72, the spring block 81 slides along the right inclined surface of the guide slide 72 and finally disengages from the inside of the latching platform 71.

[0048] like Figure 7 The following two figures, from right to left, illustrate the process of the spring block 81 moving upwards from the inside of the latching platform 71 until it disengages from the inside of the platform 71. As shown in the figures, the guide slide 72 resembles an inverted teardrop shape, with the tip of the teardrop positioned to the left of the center of the spring block 81, which is stably placed inside the latching platform 71. Therefore, when moving towards the latching platform 71, the outer periphery of the spring block 81 first adheres to the right inclined surface of the guide slide 72, and eventually slides outwards. The guide slide 72 possesses a certain degree of elasticity; the guide slide 72 originally... The opening of platform 71 is insufficient to disengage the non-deformable spring block 81. However, after the right side of the guide slide platform 72 is pushed inward by the spring block 81 and deforms, the spring block 81 can be disengaged. After the spring block 81 is disengaged, the guide slide platform 72 returns to its original shape and pushes the spring block 81 outward. When the spring block 81 moves in the opposite direction to the guide slide platform 72, the spring block 81 will first contact the right side of the fastening platform 71 and slide down along the fastening platform until it completely disengages from the fastening platform 71 and returns to its initial state.

[0049] Working principle: First, the forklift frame 1 scoops up the plate and moves down to the top of the moving seat 2. The hydraulic cylinder 9 pushes the slider 3 to slide along the slide rail 4. The first frame 51 and the second frame 52, which were originally in an angled state with the angle opening facing downwards, bulge up. At the same time, the tail slider 3 moves along the slide rail 4, causing the first locking frame 7 and the second locking frame 8 to move closer to each other and finally lock together.

[0050] Here, the tip of the latching platform 71 is positioned to the right relative to the center of the spring latch 81. Therefore, when the spring latch 81 moves towards the latching platform 71, it can move along the left side of the latching platform 71. When it passes the left side of the latching platform 71, the spring latch 81 will return to its original position due to its own elasticity. The spring latch 81 will re-enter the concave part of the latching platform 71. When the first latching frame 7 pulls the second latching frame 8, the spring latch 81 will be tightly latched on the inner side of the latching platform 71, dragging the second latching frame 8 to move synchronously.

[0051] At this point, the first frame 51, the second frame 52, the first clamping frame 7, and the second clamping frame 8 can form a stable triangle, similar to a right triangle, and the first frame 51 is almost equal to the height of the triangle. The roller 6 located at the hinge of the first frame 51 and the second frame 52 presses against the bottom of the bottom plate and lifts the stack of plates, causing the plate to tilt backward as a whole. As the hydraulic cylinder 9 retracts, it drives the triangle to move along the slide rail 4 to the tail end. Then the roller 6 presses against the plate to further increase the angle with the horizontal plane, causing its center of gravity to move further backward. Alternatively, it can be done in another way: first, the triangle is formed, and then the forklift frame 1 is lowered. After the plate comes into contact with the roller 6, it will naturally be pressed and tilted, and the center of gravity will naturally move backward. The hydraulic cylinder 9 is then pulled back to further straighten the plate.

[0052] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
