Referring to fig. 1-4, in an embodiment of the present invention, a fork carriage with a telescopic boom includes a fork carriage body, which includes two side plates 1, an upper cross beam 10 and a lower cross beam 2 connected between the two side plates 1 and parallel to each other, and an axis body 3 connected between the two side plates 11, wherein the axis body 3 is located above the lower cross beam 2 and parallel to each other. Wherein, the shaft body 3 is pivoted with a telescopic rod 4, the lower beam 2 is pivoted with a lifting oil cylinder 5, and the other end of the lifting oil cylinder 5 is connected to the middle part of the telescopic rod 4; the extension end of the telescopic rod 4 is provided with a hanging ring 6. The elevation angle of the telescopic rod 4 can be changed by extending and shortening the lifting oil cylinder 5, so that hoisting at different heights can be realized. When the telescopic rod 4 is extended, the goods in a distance can be easily hung.

Further, the telescopic rod 4 comprises a three-stage telescopic arm 41 and a three-stage oil cylinder 42, the three-stage oil cylinder 42 is parallel to the three-stage telescopic arm 41, and two ends of the three-stage oil cylinder 42 are fixedly connected. The three-stage cylinder 42 and the three-stage telescopic arm 41 have equal length, and the extension and the contraction of the three-stage cylinder 42 drive the extension and the contraction of the three-stage telescopic arm 41.

Furthermore, two limiting rings 7 are symmetrically arranged at one end of the third-stage telescopic arm 41 connected with the shaft body 3, and the limiting rings 7 are integrally connected with the third-stage telescopic arm 41 in an end connection manner; the limiting ring 7 is movably sleeved on the periphery of the shaft body 3. The third-stage telescopic arm 41 can freely rotate around the shaft body 3 to change the elevation angle. The two limit rings 7 can effectively prevent the three-stage telescopic arm 41 from being inclined left and right in the lifting process.

Further, the fork frame body also comprises an upper cross beam 10 arranged between two side plates 11; the shaft body 3 between the two limiting rings 7 is fixedly connected with a limiting block 8, and the bottom end of the limiting block 8 is fixedly connected with an upper cross beam 10. The limited block 8 is pivoted with the three-stage oil cylinder 42. This stopper 8 can also carry out the axial of certain extent to spacing ring 7 spacing, avoids spacing ring 7 to take place excessive axial skew.

Further, when the telescopic rod 4 is retracted to the shortest length, the length of the telescopic rod is not more than that of the pallet fork 9; when the lifting oil cylinder 5 is also retracted to the shortest, the telescopic rod 4 is kept in a horizontal state, and the normal forking of goods by the two forks is not influenced.

When the utility model is used, the forklift is driven to a position close to the goods and stopped, the lifting oil cylinder 5 is controlled to extend, and the telescopic rod 4 is lifted to a proper elevation angle; the three-stage oil cylinder 42 is controlled to extend to drive the three-stage telescopic arm 41 to extend to a proper length, then the goods are tied on the lifting ring 6 manually, the three-stage oil cylinder 42 and the lifting oil cylinder 5 are controlled to enable the three-stage telescopic arm 41 to retract and fall, the goods can fall onto the fork, the connection between the goods and the lifting ring 6 is unfastened, manual inspection and adjustment are carried out, the goods are ensured to be stably on the fork, and the forklift is driven to a discharging point. When only goods are hoisted, the three-stage telescopic arm 41 is controlled to be kept still after the goods are hoisted and taken, and then the forklift is driven to a designated unloading point.

Although the present specification describes embodiments, not every embodiment includes only a single embodiment, and such descriptions are provided for clarity, and it is understood that the specification is incorporated herein by reference, and the embodiments described in each embodiment may be combined as appropriate to form other embodiments, which will be apparent to those skilled in the art.
