Description

Technical Field

[0001] This utility model relates to the technical field of forklifts, specifically to a multi-functional forklift with a balance bracket. Background Technology

[0002] Counterbalance forklifts are a common type of material handling equipment. Their core feature is the use of a counterweight at the rear of the vehicle to counteract the overturning moment caused by the load of goods, ensuring operational stability. They can operate in ship holds, train carriages, and containers. By changing different attachments, counterbalance forklifts can handle a variety of goods.

[0003] Generally, existing forklifts have their loads positioned at the very front of the vehicle, shifting the center of gravity forward and making them prone to instability. This not only increases wear and tear on the vehicle but can also create safety hazards due to excessive weight at the front. Some forklifts equipped with counterweights lack the ability to adjust their balance, resulting in suboptimal balancing. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional forklift with a balance bracket to solve the above-mentioned defects caused by the prior art.

[0005] A multi-functional forklift with a balance bracket includes a chassis, a support frame, forklift arms, and a counterweight. The support frame is located on one side of the chassis, and symmetrical viewing windows are arranged on one side of the support frame. A displacement mechanism is located on one side of the support frame. This displacement mechanism adjusts the distance between the two sets of forklift arms according to the specific dimensions of the goods, and simultaneously adjusts the lifting height of the forklift arms according to the needs of goods transportation. A balance mechanism is located on the other side of the support frame. This balance mechanism adjusts the height of the counterweight according to the lifting height of the forklift arms, thereby adjusting the center of gravity of the chassis accordingly.

[0006] Preferably, the displacement mechanism includes a guide rail, a double-acting lead screw, a guide groove, a mounting plate, a forklift arm, a hydraulic cylinder, and positioning holes. The guide rail is installed on one side of the support frame, and the back of the mounting plate is connected to the outer side of the guide rail. The double-acting lead screw is connected to the outer side of the mounting plate, and two sets of forklift arms are connected to the outer side of the double-acting lead screw. The hydraulic cylinder is installed on the outer side of the support frame. The guide groove is opened on one side of the mounting plate, and positioning holes are equally spaced on the outer side of the guide groove. Positioning holes are also opened on the outer side of the forklift arm, and the forklift arm is connected to one side of the mounting plate through the positioning holes.

[0007] Preferably, the support frame is connected to the top of the hanging plate via a hydraulic cylinder located on one side.

[0008] Preferably, the support frame is connected to the outer side of the chain via sprockets symmetrically arranged on the back.

[0009] Preferably, the balancing mechanism includes a chain, a sprocket, a counterweight frame, counterweight blocks, and a guide rod. One end of the chain is symmetrically arranged at the top of the hanging plate. A sprocket is meshed with the outer side of the chain. A counterweight frame is connected through the chain. The sprockets are symmetrically arranged on the outer side of the counterweight frame. A guide rod is connected through the outer side of the counterweight frame. The bottom end of the guide rod is connected to the top of the support frame. The counterweight blocks are evenly spaced at the top of the counterweight frame.

[0010] Preferably, the counterweight is connected to one end of the two sets of chains via a counterweight frame at the bottom.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The core principle of a forklift achieving center of gravity balance by adjusting the position of the counterweight is lever balance. When the forklift arm is raised, the chain moves downward, releasing the counterweight to adjust the center of gravity. Specifically, when the forklift arm is raised, the chain moves downward, which causes the counterweight to be released, thereby adjusting the forklift's center of gravity. This design allows the forklift to maintain balance by changing the position of the counterweight when lifting goods, ensuring operational stability and safety.

[0013] 2. By directly rotating the lead screw using a handwheel or wrench, the rotational motion of the lead screw is converted into linear opposing or disjoint motion of the fork arms through the two sections of threads on the double-acting lead screw. This adjusts the fork arm spacing and avoids the problem of only being able to adjust one fork arm at a time, which could affect the forklift's center of gravity when handling goods. It allows for flexible operation without the need to replace any parts. At the same time, the slider on the back of the fork arm is embedded in the transverse groove or guide rail to ensure the straightness of the movement trajectory and prevent deviation. Meanwhile, the guide rail bears the load torque to ensure stability. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 4 As shown, a multi-functional forklift with a balance bracket includes a vehicle body 1, a support frame 2, forklift arms 9, and a counterweight 15. The support frame 2 is provided on one side of the vehicle body 1, and viewing windows 3 are symmetrically arranged on one side of the support frame 2. A displacement mechanism 5 is provided on one side of the support frame 2. The displacement mechanism 5 adjusts the distance between the two sets of forklift arms 9 according to the specific size of the goods, and adjusts the lifting height of the forklift arms 9 according to the needs of goods transportation. A balance mechanism 11 is provided on the other side of the support frame 2. The balance mechanism 11 adjusts the height of the counterweight 15 according to the lifting height of the forklift arms 9, thereby adjusting the center of gravity of the vehicle body 1 accordingly.

[0022] In this embodiment, the displacement mechanism 5 includes a guide rail 4, a bidirectional lead screw 6, a guide groove 7, a mounting plate 8, a forklift arm 9, a hydraulic cylinder 10, and positioning holes 17. The guide rail 4 is installed on one side of the support frame 2. The back of the mounting plate 8 is connected to the outer side of the guide rail 4. The bidirectional lead screw 6 is connected to the outer side of the mounting plate 8. Two sets of forklift arms 9 are connected to the outer side of the bidirectional lead screw 6. The hydraulic cylinder 10 is installed on the outer side of the support frame 2. The guide groove 7 is opened on one side of the mounting plate 8. Positioning holes 17 are equally spaced on the outer side of the guide groove 7. Positioning holes 17 are also opened on the outer side of the forklift arm 9. The forklift arm 9 is connected to one side of the mounting plate 8 through the positioning holes 17. By utilizing the two sections of threads with opposite directions on the bidirectional lead screw 6, the rotational motion of the bidirectional lead screw 6 is converted into the linear opposing or disjoint motion of the forklift arm 9.

[0023] In this embodiment, the support frame 2 is connected to the top of the hanging plate 8 via a hydraulic cylinder 10 on one side. The hydraulic cylinder 10 drives the hanging plate 8 to move vertically upward, thereby adjusting the vertical upward movement of the hanging plate 8 and the forklift arm 9.

[0024] In this embodiment, the support frame 2 is connected to the outer side of the chain 12 by sprockets 13 symmetrically arranged on the back. The symmetrically arranged chain 12 and sprockets 13 engage and guide the counterweight 15 accordingly.

[0025] In this embodiment, the balancing mechanism 11 includes a chain 12, a sprocket 13, a counterweight frame 14, counterweight blocks 15, and a guide rod 16. One end of the chain 12 is symmetrically arranged at the top of the hanging plate 8. The sprocket 13 is meshed with the outer side of the chain 12. The counterweight frame 14 is connected through the chain 12. The sprocket 13 is symmetrically arranged on the outer side of the counterweight frame 14. The guide rod 16 is connected through the outer side of the counterweight frame 14. The bottom end of the guide rod 16 is connected to the top of the support frame 2. The counterweight blocks 15 are evenly spaced at the top of the counterweight frame 14. The symmetrically arranged guide rod 16 guides both sides of the counterweight frame 14 to prevent the counterweight frame 14 from shaking.

[0026] In this embodiment, the counterweight 15 is connected to one end of two sets of chains 12 via a counterweight frame 14 at the bottom. The appropriate number of counterweights 15 is selected according to the weight of the goods, thereby adjusting the height of the counterweight frame 14 accordingly.

[0027] In practical applications, this multi-functional forklift with a balance bracket includes the following tasks:

[0028] Step 1: The operator first installs the corresponding weight of counterweight 15 on the outside of the counterweight frame 14, and selects the corresponding number or weight of counterweight 15 according to the general weight of the goods. The chain 12 is installed on both sides of the hanging plate 8 and the counterweight frame 14 respectively. The chain 12 is supported and guided by the symmetrically arranged sprockets 13. The back of the two sets of forklift arms 9 is connected to the outside of the guide groove 7. The double-acting screw 6 on the outside is connected to the inner end nut of the two sets of forklift arms 9.

[0029] Step 2: Directly rotate the double-acting screw 6 using a handwheel or wrench to convert the rotational motion of the double-acting screw 6 into the linear opposing or disengaging motion of the forklift arm 9. At the same time, the slider on the back of the forklift arm 9 is embedded in the guide groove 7. Adjust the spacing of the forklift arm 9 according to the spacing of the goods or shelves. After the adjustment of the forklift arm 9 is completed, insert the bolt into the positioning hole 17 so that the bottom end of the bolt is connected to one side of the hanging plate 8, thereby achieving the positioning treatment of the hanging plate 8 and the outer side of the forklift arm 9, and preventing the forklift arm 9 from shaking during the lifting process.

[0030] Step 3: When it is necessary to transfer and lift the goods, the vehicle body 1 drives the support frame 2 to move, so that the forklift arm 9 on one side is inserted into the bottom of the goods. Then, the hydraulic cylinder 10 drives the hanging plate 8 and the forklift arm 9 on one side to move vertically upward, so that the guide rail 4 on one side of the support frame 2 can vertically lift the hanging plate 8 and the forklift arms 9 on both sides to lift the goods. The vehicle body 1 drives the forklift arm 9 to move, and then the hydraulic cylinder 10 is released to place the goods on the forklift arm 9 onto the truck.

[0031] Step 4: When the hanging plate 8 on one side of the support frame 2 moves upward, the chain 12 at the top of the hanging plate 8 moves vertically upward, while the sprocket 13 engages with the chain 12 and moves downward. The chain 12 drives the counterweight frame 14 and the counterweight block 15 to move vertically downward. At the same time, the guide rods 16 on both sides guide the sides of the counterweight frame 14. When the forklift arm 9 is lifted, the chain 12 moves downward, thereby releasing the counterweight frame 14 and the counterweight block 15. This design allows the forklift to maintain balance when lifting heavy objects and avoids instability of the goods on the vehicle body 1 and the front forklift arm 9 due to an excessively high center of gravity.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
