[0001] This utility model relates to the manufacturing field of large-tonnage forklifts, and in particular to a forklift side-shifting fork carriage. Background Technology
[0002] With the rapid development of my country's logistics and manufacturing industries, enterprises, ports, and construction sites have an increasing need for large-tonnage forklifts. The volume and weight of goods are also gradually increasing. In order to facilitate the picking up of goods and improve the flexibility and handling efficiency of forklifts, drivers are required to perform high-level operations to ensure accurate picking up of goods during loading and unloading.
[0003] Normally, when picking up goods, it is necessary to make slight adjustments to the left and right positions of the forks so that the forks are aligned with the slots of the goods, without having to back up the forklift and readjust the entire position of the forklift. A fork carriage with side shift can easily achieve this function and improve handling efficiency.
[0004] To enable the forklift forks to move to the left and right, the common practice is to attach a side-shifting mechanism to the existing forklift fork carriage. However, this approach increases the forklift's off-load distance and weight, thus reducing the forklift's load capacity. Utility Model Content

Detailed Implementation
[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.
[0024] refer to Figure 1 As shown in the figure, this application discloses a forklift side-shifting fork carriage, including a lifting frame 1, a side-shifting frame 2, a connecting shaft 3, a hydraulic cylinder 4, and forks 5; one side of the side-shifting frame 2 is slidably connected to the lifting frame 1 through the connecting shaft 3, and the other side of the side-shifting frame 2 is fixedly connected to the forks 5; the piston rod end of the hydraulic cylinder 4 is fixedly connected to the side-shifting frame 2, and the end of the hydraulic cylinder 4 away from the piston rod end is fixedly connected to the lifting frame 1.
[0025] refer to Figure 2 , 3 As shown, a lifting frame support 11 is provided on the top of the lifting frame 1 near the side-shifting frame 2. In this embodiment, there are two lifting frame support 11s. (Refer to...) Figure 4 As shown, the top of the side-shifting frame 2 is provided with multiple side-shifting frame support seats 21. In this example, there are a total of 4 side-shifting frame support seats 21. The lifting frame support seat 11 is located between two spaced side-shifting frame support seats 21. The connecting shaft 3 passes through the two side-shifting frame support seats 21 and the middle lifting frame support seat 11.
[0026] A connecting bushing 31 is provided between the connecting shaft 3 and the lifting frame support 11. The connecting bushing 31 can reduce the friction between the connecting shaft 3 and the lifting frame support 11. In this example, the connecting bushing 31 is a copper bushing.
[0027] A bushing baffle 311 is provided at both ends of the connecting bushing 31. The bushing baffle 311 can prevent the connecting bushing 31 from falling off during lateral movement. The bushing baffle 311 is fixed to both sides of the lifting frame support seat 11 by bolts.
[0028] Connecting shaft baffles 32 are provided at both ends of the connecting shaft 3. The connecting shaft baffles 32 can prevent the connecting shaft 3 from falling off during lateral movement. The connecting shaft baffles 32 are fixed to the side of the lateral movement frame support 21 by bolts.
[0029] A slider 12 is provided on the lower part of the lifting frame 1 near the side shift frame 2. In this example, the slider 12 is made of nylon. The surface of the slider 12 is provided with oil channels, and grease such as butter can be added into the oil channels. The slider 12 can reduce the friction of the side shift frame 2 when it moves left and right, and the slider 12 can withstand the force in the front and back directions when the forklift is carrying goods.
[0030] A slider baffle 121 is provided on one side of the slider 12. The slider baffle 121 is fixed to the lifting frame 1 by bolts, and at the same time, it restricts the slider 12 to the lifting frame 1 to prevent it from falling off during lateral movement.
[0031] When the forklift is in operation, the forks 5 often need to tilt forward and backward at a certain angle. To prevent the side shift frame 2 from rotating around the connecting shaft 3 when the forks 5 tilt forward, a stop block 22 is provided on the lower part of the side shift frame 2 near the lifting frame 1. The stop block 22 is fixed to the side shift frame 2 by bolts. A boss 13 is provided at the corresponding position on the side of the lifting frame 1 near the side shift frame 2. The boss 13 is long and narrow. When the side shift frame 2 moves left and right, the stop block 22 is locked on the boss 13 to prevent the side shift frame 2 from rotating around the connecting shaft 3.
[0032] The back of the fork 5 is detachably mounted on the top of the side shifter 2. The spacing between the upper and lower crossbeams of the side shifter 2 meets the international installation grade size requirements. Therefore, the fork 5 can be interchanged with other attachments of the same installation grade to meet the multi-purpose function of one vehicle.
[0033] refer to Figure 3 , 4 As shown in this example, the hydraulic cylinder 4 is a hydraulic oil cylinder. A first hydraulic cylinder mounting base 14 is provided on the side of the lifting frame 1 near the side-shifting frame 2; a second hydraulic cylinder mounting base 23 is provided on the side of the side-shifting frame 2 near the lifting frame 1. The piston rod end of the hydraulic cylinder 4 is fixedly connected to the second hydraulic cylinder mounting base 23 via a pin, and the end of the hydraulic cylinder 4 away from the piston rod end is fixedly connected to the first hydraulic cylinder mounting base 14 via a pin. The left and right lateral movement function of the side-shifting frame 2 is achieved through the hydraulic cylinder 4. By extending and retracting the piston rod of the hydraulic cylinder 4, a lateral movement of 150mm can be achieved on each side of the side-shifting frame 2.
[0034] The working principle and beneficial effects are as follows: This utility model uses a hydraulic cylinder 4 to make the side shift frame 2 move left and right, and the side shift frame 2 will not rotate around the connecting shaft 3 when moving. Its structure is simple, with low weight and low load distance, and it is easy to manufacture. It can easily solve the problem of accurately inserting the forks into the slot or stacking the goods when the forklift is loading and unloading by moving left and right.
