Description

Technical Field

[0001] This utility model relates to the field of side shifter technology, and in particular to a forklift-integrated side shifter. Background Technology

[0002] Forklifts are versatile, flexible, and efficient material handling equipment. Typically, a standard forklift is equipped with a pair of forks, primarily used to hold and support goods placed on pallets. The forklift then uses its lifting, tilting, and other actions to stack and unload goods. However, when operating a forklift for stacking and unloading, there is an inevitable slight misalignment between the pallet picked up and its intended position. This necessitates the forklift operator to repeatedly adjust the forklift to ensure the pallet is in the correct location, increasing the difficulty of operation and reducing efficiency. Side shifters are forklift-specific attachments that allow the forks to move laterally. Traditional side shifters only allow for left-right lateral movement of the forks. When loading and unloading different goods, manual adjustment of the fork spacing is still required to accommodate different items. This not only risks injury due to improper operation but is also cumbersome, time-consuming, and labor-intensive, impacting work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where traditional side shifters can only achieve left and right lateral movement of the forks. When loading and unloading different goods, it is still necessary to manually adjust the spacing between the forks to adapt to different goods. This is not only cumbersome to operate, but also time-consuming and labor-intensive, affecting work efficiency. Therefore, this invention proposes a forklift-integrated side shifter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A forklift-integrated side shifter includes a side shift frame and two forks, with the forks disposed on one side of the side shifter. The integrated side shifter also includes a side shift mechanism disposed on one side of the side shift frame, which is used to drive the two forks to move left and right together.

[0006] The adjustment mechanism is located on one side of the side shifter and is used to adjust the distance between the two forks.

[0007] Preferably, the lateral displacement mechanism includes: a connecting block, a concave block, an electro-hydraulic cylinder, two first sliding blocks, and a lateral displacement block;

[0008] The side-shifting frame has two first sliding grooves that are adapted to the first sliding block. The first sliding block is slidably disposed in the first sliding groove and fixedly connected to the side-shifting block. The side-shifting block has a mounting hole, and the concave block is disposed in the mounting hole. The two ends of the connecting block are fixedly connected to the side-shifting frame and the concave block respectively. The electric hydraulic cylinder is fixedly disposed in the concave block. The two ends of the telescopic rod of the electric hydraulic cylinder are fixedly connected to the inner walls on both sides of the mounting hole respectively. The concave block and the adjustment mechanism cooperate with each other.

[0009] Furthermore, through the cooperation of the connecting block, concave block, electric hydraulic cylinder, two first sliding blocks and side shifting block, the two forks can be driven to move left and right together.

[0010] Preferably, the adjustment mechanism includes: a motor, a rotating column, a driving gear, two driven racks, two second sliding blocks, and two connecting columns;

[0011] The lower end of the concave block is provided with a third sliding groove that matches the sliding plate. The sliding plate is slidably disposed in the third sliding groove. Both ends of the sliding plate are fixedly connected to the inner walls of the mounting holes on both sides. The motor is fixedly connected to the lower end of the sliding plate. One end of the rotating column is keyed to the output shaft of the motor. The other end of the rotating column is fixedly connected to the drive gear. Two driven racks are symmetrically disposed on both sides of the drive gear and mesh with the drive gear. Two sliding holes are provided at the bottom of the inner side of the mounting groove. A second sliding block is disposed in the sliding hole. The upper end of the connecting column is fixedly connected to one end of the driven rack. The lower end of the connecting column passes through the second sliding block and is fixedly connected to the fork. The two forks are of different lengths, and the end of the fork away from the connecting column is horizontally disposed.

[0012] Furthermore, the distance between the two forks can be adjusted through the interaction of the motor, sliding plate, rotating column, driving gear, two driven racks, two second sliding blocks, and two connecting columns.

[0013] Preferably, a second sliding groove is provided on the top inner side of the side-moving block, and a sliding column is fixedly connected to the upper end of the concave block, with the upper end of the sliding column slidably disposed in the second sliding groove.

[0014] Furthermore, the sliding column can provide support for the concave block, making it more stable.

[0015] Preferably, an auxiliary sliding block is slidably disposed in both sliding holes, the auxiliary sliding block is symmetrically disposed with the second sliding block, a support column is fixedly connected to the upper end of the auxiliary sliding block, and the upper end of the support column is fixedly connected to the other end of the driven rack.

[0016] Furthermore, by setting up auxiliary sliding blocks and support columns, the driven rack can be supported, making the driven rack more stable.

[0017] Beneficial effects:

[0018] 1. Through the cooperation of the connecting block, concave block, electric hydraulic cylinder, two first sliding blocks and side shifting block, the two forks can be driven to move left and right together.

[0019] 2. Through the cooperation of the motor, rotating column, driving gear, two driven racks, two second sliding blocks and two connecting columns, the distance between the two forks can be adjusted, avoiding injury caused by improper operation when the operator manually adjusts the fork distance. It is simple to operate, saves time and effort, and can significantly improve work efficiency.

[0020] In this invention, the cooperation between the lateral shift mechanism and the adjustment mechanism allows the two forks to move left and right together, thereby avoiding the forklift driver having to adjust the forklift multiple times to insert the pallet into the correct position. At the same time, the distance between the two forks can also be adjusted, avoiding manual adjustment. Attached Figure Description

[0037] The working principle of this utility model:

[0038] First, connect the equipment requiring electricity to an external power source. Connect the inlet and outlet of the electric hydraulic cylinder 3 to the oil pipes pre-installed on the forklift. Start the electric hydraulic cylinder 3; the telescopic rod on one side of the electric hydraulic cylinder 3 extends, while the telescopic rod on the other side retracts, thereby pushing the moving block 5 to move. The moving block 5 is pushed, causing the first sliding block 4 to slide within the first sliding groove, thus moving the first sliding block 4 and the side-moving block 5 together. The movement of the side-moving block 5 drives the sliding plate 61 to move, which in turn drives the motor 6, the rotating column 7, the driving gear 8, the driven rack 9, the two second sliding blocks 10, and the two auxiliary sliding blocks. 101. The two connecting columns 11, the two supporting columns 111, and the two forks 12 move together, while the sliding column 13 moves simultaneously within the third sliding groove. By moving the two forks 12 left and right, the insertion position of the pallet can be adjusted. The motor 6 is started, and the output shaft of the motor 6 rotates, causing the rotating column 7 to rotate and the drive gear 8 to rotate together. The rotation of the drive gear 8 causes the two driven racks 9 to move left and right. The movement of the driven racks 9 causes the second sliding block 10, the auxiliary sliding block 101, the connecting column 11, and the supporting column 111 to move, thereby causing the two forks 12 to move closer to each other or further away from each other, thus adjusting the distance between the two forks 12.
