Detailed Description

The following description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, which are set forth in the accompanying drawings and in fig. 1-5, to provide a better understanding of the function and features of the utility model.

Referring to fig. 1 to 5, a side shift fork carriage for a small tonnage forklift according to an embodiment of the present invention includes a lifting frame 1, a side shift transmission mechanism 2, and a side shift frame 3; the side shift frame 3 is connected to the lifting frame 1 through the side shift transmission mechanism 2. The lifting frame 1 is used as a main body of the fork frame, is arranged in an inner gantry of the forklift in a roller form, and plays roles of lifting and descending the fork frame.

The hoisting frame 1 comprises a first upper cross beam 11 and a first lower cross beam 12 which are horizontally arranged; a first sliding groove is formed on the top surface of the first upper cross beam 11, and a plurality of upper sliding blocks 13 are arranged on the first sliding groove; a plurality of lower sliders 14 are mounted on the side surfaces of the first lower beam 12, and a plurality of fixing plates 15 are connected to the top surface of the first lower beam 12.

The side moving frame 3 comprises a second upper cross beam 31 and a second lower cross beam 32 which are horizontally arranged; a second sliding groove is formed on the bottom surface of the second upper cross beam 31, the second sliding groove is matched with the first sliding groove, and the upper sliding block 13 is positioned between the second upper cross beam 31 and the first upper cross beam 11; the top surface of the second lower beam 32 forms an upward convex clamping edge along the length direction, the plurality of check blocks 4 are fixed on the fixing plate 15 through bolts, a third sliding groove is formed at the bottom of each check block 4, the clamping edge can be clamped in the third sliding groove in a sliding manner along the third sliding groove, and the lower sliding block 14 is positioned between the second lower beam 32 and the first lower beam 12. The stop block 4 can prevent the side shift frame 3 from shaking in the front and rear tilting of the forklift mast.

The side shift transmission mechanism 2 comprises a side shift oil cylinder 21, two pin shafts 22 and two fixed seats 23; one fixed seat 23 is fixed on one side edge of the side moving frame 3, and the other fixed seat 23 is fixed at the bottom of the first upper cross beam 11; the first end of the side-shifting oil cylinder 21 is connected with a fixed seat 23 through a pin 22, and the second end of the side-shifting oil cylinder 21 is connected with another fixed seat 23 through another pin 22.

The top surface of the first upper cross member 11 forms a fourth runner for the mounting of the forks.

The position of the fourth chute, which corresponds to the upper slide block 13, is provided with a threaded hole for installing a grease nipple for use, so that grease can be conveniently filled, and the resistance during lateral movement can be reduced.

The second lower beam 32 is provided with a through hole corresponding to the lower slider 14, so that grease can be conveniently filled.

The surfaces of the upper sliding block 13 and the lower sliding block 14 are provided with oil grooves, so that lubricating grease can be conveniently filled.
