Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 4, the truck mainly comprises a traveling chassis assembly 6, a vehicle control assembly 7, a boom rotation assembly 8, a boom 9, a telescopic boom 1 and a front arm 2.

The walking chassis assembly 6 is used for driving the vehicle to integrally advance, the vehicle control assembly 7 is installed on the walking chassis assembly 6 and mainly used for controlling various operation procedures of the vehicle, the upper end of the walking chassis assembly 6 is also provided with a large arm rotating assembly 8, the large arm rotating assembly 8 is used for controlling a large arm 9 to swing in the horizontal direction and the vertical direction so as to adapt to cargo transportation requirements of different positions, the telescopic arm 1 is connected to the front end of the large arm 9 in a sliding mode and can extend and retract within a small range, the front arm 2 is driven to achieve fine adjustment of the distance between the front arm 2 and the cargo, adaptive ground distance compensation can be achieved by matching with a corresponding sensor, and the front arm 2 can be attached to the cargo on different horizontal positions all the time so as to complete the transportation process.

As shown in fig. 1, the present invention provides a front arm posture adjusting structure of a lift truck, which comprises a supporting member 3 connected with the front end of a telescopic arm 1, a driving member 4 installed on the supporting member 3, and a connecting member 5 for connecting a front arm 2, wherein the driving member 4 drives the connecting member 5 to swing up and down in the vertical direction, the connecting member 5 drives the front arm 2 to change in height position, and the front arm 2 is always kept horizontal in the moving process.

Specifically, as shown in fig. 2 and 3, the supporting member 3 includes a supporting frame 31, a top end of the supporting frame 31 is fixedly connected to a bottom end of the telescopic arm 1, a first hinge seat 32 is disposed on the supporting frame 31, the first hinge seat 32 is hinged to one end of a nitrogen spring 33, the other end of the nitrogen spring 33 is rotatably connected to a second hinge seat 34 through a hinge shaft, and the second hinge seat 34 is connected to the connecting member 5.

Further, the driving part 4 includes two sets of driving motors 41 symmetrically disposed, an output end of each set of driving motor 41 is connected to an input end of the corner speed reducer 42, the corner speed reducer 42 is fixedly mounted on an inner side wall of the supporting frame 31, an output end of the corner speed reducer 42 is connected to a driving gear 43, and the driving gear 43 is used for driving the connecting part 5 to swing.

Furthermore, the connecting part 5 includes a connecting beam 51, swing plates 52 integrally connected to two ends of the connecting beam 51, and a connecting bracket 53 fixedly connected to the front arm 2, the second hinge seat 34 is fixedly mounted on the connecting beam 51, the swing plates 52 are rotatably connected to the telescopic arm 1 through a rotating shaft, the bottom of the swing plates 52 is provided with groove teeth 54, and the driving gear 43 is engaged with the corresponding groove teeth 54.

Since the weights of the front arms 2 and the connecting beam 51 are supported by the two-sided slot teeth 54, and the supporting force provided by the two-sided slot teeth 54 hardly supports the entire weights of the front arms 2 and the connecting beam 51, which will easily cause the swing plate 52 to deflect additionally under heavy pressure, the nitrogen spring 33 is installed between the supporting frame 31 and the connecting beam 51 through the first hinge seat 32 and the second hinge seat 34, and the nitrogen spring 33 can provide a supporting buffer for the front arms 2 and relieve the load of the driving motor 41, so that the stability of the front arms 2 during posture adjustment can be ensured.
