DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1-2 As shown, a counterweight fixing and anti-slip device for a new energy forklift includes a fixed frame 1, a lifting assembly 2 is arranged on the front side of the fixed frame 1, a supporting assembly 3 is arranged on the rear side of the fixed frame 1, the supporting assembly 3 includes a counterweight 38, an adjusting assembly 4 is arranged on the front side of the supporting assembly 3, when the goods rise to a certain height, the counterweight block is automatically triggered to move backward, effectively adjusting the center of gravity of the forklift and maintaining its stability, a disassembly assembly 5 is arranged on the rear side of the supporting assembly 3, reducing the steps of manual handling and fixing of the counterweight block, and a clamping assembly 6 is arranged on the upper end of the supporting assembly 3.

[0035] The above-mentioned support assembly 3, adjustment assembly 4, disassembly assembly 5, clamping assembly 6 and other structures are all located at the lower end of the forklift chassis. The tires of the forklift are thicker and taller, so there is enough space at the lower end to install the structure. The attached drawings are for reference only and need to be modified according to actual needs in production.

[0036] During the operation of this embodiment, through the cooperation of the lifting component 2, the support component 3, and the adjustment component 4, when the lifting component 2 rises to a certain position, the adjustment component 4 will drive the support component 3 to move backward as a whole, so that the support component 3 can automatically adjust its position according to the change of the cargo height, effectively adjust the center of gravity distribution of the forklift, and improve the flexibility and stability of the forklift. In addition, by utilizing the cooperation between the disassembly component 5 and the clamping component 6, the counterweight 38 can be quickly disassembled and installed while ensuring its anti-slip property, thereby simplifying the installation process and improving the installation efficiency.

[0037] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve the effect of automatically adjusting the center of gravity according to the change of the height of the cargo.

[0038] For details, see Figure 1-8 The lifting assembly 2 includes a hydraulic device 21, which is fixedly connected to the upper end of the fixed frame 1. The hydraulic device 21 can drive the fixed frame 22, the door frame 23 and the fork 24 to be lifted as a whole to transport the goods. The output end of the hydraulic device 21 is fixedly connected to the fixed frame 22, the front side of the fixed frame 22 is provided with a door frame 23, and the front side of the door frame 23 is installed with a fork 24. The left and right sides of the fixed frame 1 are rotatably connected with a connecting seat 25. The connecting seat 25 consists of a rotating shaft and two blocks, which can be fixed to the rear structure and will not affect the change of the overall tilt angle of the fixed frame 1 and the lifting assembly 2 when working.

[0039] The hydraulic device 21 mentioned above is prior art and will not be described in detail in the present invention. Its main working principle is as follows:

[0040] Starting and oil supply: When the forklift engine is started, the hydraulic pump starts working, sucking oil from the oil tank and increasing its pressure.

[0041] Oil flow: High-pressure oil enters the hydraulic valve through the oil pipe, and the hydraulic valve controls the flow direction of the oil according to operating instructions.

[0042] Piston movement: When the oil enters the hydraulic cylinder, the piston moves upward due to the pressure. During this process, the volume of the oil in the hydraulic cylinder decreases and the pressure increases, thereby pushing the fork 24 up.

[0043] Control and regulation: The hydraulic valve controls the rising speed and height of the fork 24 by adjusting the flow and pressure of the oil. At the same time, the overflow valve ensures that the system pressure does not exceed the set value to protect the system safety.

[0044] Load balance: During the ascending process of the fork 24, the hydraulic system will automatically adjust the pressure and flow of the oil according to the size of the load to keep the load balanced and stable.

[0045] For further information, see Figure 4-7 The support assembly 3 also includes a U-shaped support seat 31, the front side of the U-shaped support seat 31 is fixedly connected to the connecting seat 25, and a through slot 32 is provided at the lower end of the U-shaped support seat 31 to facilitate the disassembly and installation of the counterweight 38. A mounting slot 33 is provided on the inner surface of the through slot 32, a sliding slot 34 is provided on the vertical part of the front U-shaped support seat 31, and three telescopic rods 35 are fixedly connected to the vertical part of the rear U-shaped support seat 31.

[0046] Furthermore, the front ends of the three telescopic rods 35 are commonly fixedly connected with an L-shaped adjustment seat 37. The telescopic rods 35 can limit the L-shaped adjustment seat 37 so that it can move forward and backward stably. The L-shaped adjustment seat 37 is L-shaped, and its angle is greater than ninety degrees. The horizontal part of the L-shaped adjustment seat 37 is provided with a groove to facilitate the passage of the counterweight 38. The counterweight 38 can also be limited to prevent the counterweight 38 from separating from the L-shaped adjustment seat 37. The lower end of the L-shaped adjustment seat 37 is slidably connected to the U-shaped support seat 31, and the front end of the inclined part of the L-shaped adjustment seat 37 is fixedly connected to the limiting seat 371, and the counterweight 38 contacts the inner surface of the L-shaped adjustment seat 37.

[0047] For further information, see Figure 5 and Figure 8 The adjusting component 4 includes two rotating shafts 41, the upper ends of the two rotating shafts 41 are fixedly connected to the fixed frame 22, and the sides of the two rotating shafts 41 close to each other are rotatably connected to the rotating rod 42, so that the telescopic plate 43, the connecting plate 44, the connecting frame 45 and the roller 46 can still be normally connected to the limit seat 371 when the fixed frame 1 and the lifting component 2 are tilted as a whole. The outer surface of the rotating rod 42 is fixedly connected to the telescopic plate 43, and the lower end of the telescopic plate 43 is fixedly connected to the limiting block 431, which is convenient for limiting the telescopic plate 43. When the limiting block 431 rises to the highest point of the connecting plate 44, it will be stuck with the connecting plate 44. At this time, continuing to rise will drive the structure below the connecting plate 44 to be lifted together. The outer surface of the limiting block 431 is slidably connected to the connecting plate 44, and the outer surface of the connecting plate 44 is slidably connected to the sliding groove 34.

[0048] For further information, see Figure 5One end of the connecting plate 44 close to the L-shaped adjustment seat 37 is fixedly connected to two connecting frames 45, and the ends of the two connecting frames 45 close to each other are connected to a roller 46 for common rotation. The roller 46 is slidably connected to the inner surface of the limit seat 371. When the roller 46 slides on the inner surface of the limit seat 371, it can drive the L-shaped adjustment seat 37 and the limit seat 371 to move forward or backward as a whole, thereby changing the position of the counterweight 38, adjusting the center of gravity distribution of the forklift, and effectively enhancing the stability of the forklift.

[0049] Starting the hydraulic device 1 21 drives the fixed frame 2 22, the door frame 23 and the fork 24 to be lifted as a whole. When the limit block 431 rises to the highest point of the connecting plate 44, it will be stuck with the connecting plate 44. At this time, continuing to rise will drive the connecting plate 44 to rise, so that the connecting frame 45 and the roller 46 are lifted. The connecting frame 45 will slide in the limit seat 371 during the lifting process, pushing the L-shaped adjustment seat 37 to move forward, thereby changing the position of the counterweight 38 and adjusting the center of gravity distribution of the forklift.

[0050] Therefore, this solution causes the adjustment component 4 to drive the support component 3 to move backward by changing the height of the cargo, thereby changing the position of the counterweight 38, effectively adjusting the center of gravity of the forklift to maintain its stability, and greatly reducing the safety risks during operation, thereby preventing safety accidents caused by center of gravity shift.

[0051] Embodiment 3: Based on Embodiment 1, this embodiment is to simplify the replacement process of the counterweight 38 and improve the working efficiency.

[0052] For details, see Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11 The disassembly component 5 includes a fixed seat 51, the upper end of the fixed seat 51 is fixedly connected to the forklift chassis, the front side of the fixed seat 51 is fixedly connected to the rear side of the U-shaped support seat 31, and a hydraulic device 2 52 is fixedly installed on the rear side wall of the inner surface of the fixed seat 51. The output end of the hydraulic device 2 52 is fixedly connected to a fixed plate 53, and the front end of the fixed plate 53 is fixedly connected to a sliding plate 54. The outer surface of the sliding plate 54 is slidably connected to the installation groove 1 33. The hydraulic device 2 52 can pull the fixed plate 53 and the sliding plate 54 out of the installation groove 1 33 as a whole, so that the counterweight 38 can fall directly, thereby realizing quick disassembly.

[0053] Furthermore, the upper surface of the sliding plate 54 is provided with a plurality of mounting grooves 55, and the inner surfaces of the plurality of mounting grooves 55 are provided with a plurality of sliding wheels 56. The outer surfaces of the plurality of sliding wheels 56 are slidingly connected to the lower end of the counterweight 38, and the lower end of the counterweight 38 is directly in contact with the sliding plate 54. The sliding wheels 56 can reduce the pressure and friction force brought by the counterweight 38 to the sliding plate 54, so that the sliding plate 54 can slide normally.

[0054] For further information, see Fig.11 The clamping assembly 6 includes a rack 61, and the left and right sides of the sliding plate 54 are fixedly connected to the rack 61. The sides of the two racks 61 that are away from each other are meshed with gear 1 62. Gear 1 62 can play a guiding role, so that the rotation direction of gear 2 63 meshed with it is opposite to that of gear 1 62. The outer surfaces of the two gears 1 62 are meshed with gear 2 63. Gear 2 63 can drive the clamping block 65 to move toward the middle to clamp and limit the balance weight 38. The upper surfaces of the two gears 2 63 are fixedly connected with a rotating seat 64, and the outer surfaces of the two rotating seats 64 are rotatably connected to the U-shaped support seat 31.

[0055] For further information, see Fig.10 and Fig.11 The upper ends of the two rotating seats 64 are fixedly connected with clamping blocks 65, and the adjacent sides of the two clamping blocks 65 are provided with titanium nitride coatings 66. The titanium nitride coating 66 is a common golden coating with high hardness and wear resistance, smooth surface and low friction coefficient. It can limit the left and right sides of the balancing weight 38 without hindering the forward and backward movement of the balancing weight 38. The adjacent sides of the two titanium nitride coatings 66 are slidably connected with the balancing weight 38. The distance that the balancing weight 38 moves forward and backward is limited, and it will not separate from the titanium nitride coatings 66 on both sides.

[0056] When the counterweight 38 needs to be replaced, the hydraulic device 2 52 is first started to drive the fixed plate 53 and the sliding plate 54 to be pulled out as a whole. During the pulling process, the rack 61 is meshed with the gear 1 62, so that the gear 1 62 rotates clockwise, and then the gear 2 63 rotates counterclockwise, driving the rotating seat 64, the clamping block 65, and the titanium nitride coating 66 to rotate counterclockwise together, so that the clamping block 65 releases the clamping limit of the counterweight 38. When the sliding plate 54 is pulled out as a whole, the counterweight 38 will fall directly onto the mobile device placed by the staff below, and then the new counterweight 38 is pulled out and replaced. When installing, the new counterweight 38 needs to be lifted by a jack. 38 is lifted upward, and then the hydraulic device 2 52 is started to close the sliding plate 54. When it is half closed, the jack is taken away, and the sliding plate 54 continues to slide. At this time, the sliding wheel 56 rubs against the counterweight 38. The sliding wheel 56 can help the sliding plate 54 to move more smoothly, and during the movement, the rack 61 will still mesh with the gear 1 62. The subsequent working process is exactly the opposite of the working process of disassembling the counterweight 38 described above, so it will not be repeated. When the sliding plate 54 is completely merged, the clamping block 65 also clamps the counterweight 38 to prevent the counterweight 38 from shaking or slipping in the left and right positions.

[0057] Therefore, through the cooperation between the disassembly component 5 and the clamping component 6, the present invention can simultaneously achieve the limitation or release of the balance weight 38 when installing or disassembling it, thereby preventing the balance weight 38 from slipping and simplifying the replacement process of the balance weight 38, thereby improving work efficiency.

[0058] It should be particularly noted that the specific installation method, circuit connection method and control method of the hydraulic device 1 21 and the hydraulic device 2 52 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0059] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
