The drive assembly is fixed on the bracket, and the traveling wheels are fixed on the drive ends of the drive assembly; the lower end of the lifting oil cylinder is fixed on the bracket, the top of the rear side of the vehicle frame is rotatably connected to the piston rod of the lifting oil cylinder, and the operating handle assembly is connected to the bracket; however, in the existing structure of the goods handling vehicle, the traveling wheels in the existing goods handling vehicle have poor grip, that is, when the existing goods handling vehicle is applied to an unpaved road surface, for example, when applied to the unpaved road surface of a construction site, there will be a situation of difficult progress. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an off-road goods handling vehicle, in which the traveling wheels inside have the advantage of strong grip, so that when the goods handling vehicle is applied to an unpaved road surface, the traveling ability of the goods handling vehicle can also be ensured, that is, reliable handling of goods can be realized.

[0004] The utility model provides an off-road goods handling vehicle, which includes a vehicle frame, a traveling assembly, a lifting oil cylinder, and an operating handle assembly; the traveling assembly includes a bracket, a drive assembly, and traveling wheels. The drive assembly is fixed on the bracket, and the traveling wheels are fixed on the drive ends of the drive assembly; the lower end of the lifting oil cylinder is fixed on the bracket, the top of the rear side of the vehicle frame is rotatably connected to the piston rod of the lifting oil cylinder, and the operating handle assembly is connected to the bracket; on one side of the outer peripheral wall of the traveling wheel, a plurality of "Y"-shaped first grooves are circumferentially spaced, the symmetry line of the first grooves is parallel to the axis of the traveling wheel, and on the other side of the outer peripheral wall of the traveling wheel, a plurality of "Y"-shaped second grooves are circumferentially spaced, and the symmetry line of the second grooves is parallel to the axis of the traveling wheel; the plurality of first grooves and the plurality of second grooves are spaced apart in the circumferential direction of the traveling wheel, and the two inner end portions of each first groove are respectively communicated with one of the inner end portions of two adjacent second grooves.

[0005] After the utility model adopts the above traveling wheel structure, under the action of the first grooves and the second grooves, the grip of the traveling wheels can be improved, so that when the goods handling vehicle is applied to an unpaved road surface, the traveling ability of the goods handling vehicle can also be ensured, that is, reliable handling of goods can be realized.

[0006] In a possible implementation, two connecting plates arranged symmetrically left and right are fixed to the upper part of the rear side of the frame. The upper end of the piston rod is inserted into the gap between the two connecting plates, and the piston rod is rotatably connected to the two connecting plates through a first rotating shaft. One end of the first rotating shaft is integrally formed with a first connecting ear that radially protrudes from the first rotating shaft, and the first connecting ear is fixed to the corresponding connecting plate through a first bolt. After adopting this structure, under the action of the first rotating shaft, the piston rod can be reliably rotatably connected to the two connecting plates, that is, the top of the rear side of the frame can be reliably rotatably connected to the piston rod of the lifting cylinder. In addition, since one end of the first rotating shaft is integrally formed with a first connecting ear that radially protrudes from the first rotating shaft, and the first connecting ear is fixed to the corresponding connecting plate through a first bolt, the axial movement of the first rotating shaft can be restricted, that is, the situation where the first rotating shaft disengages from the piston rod and the two connecting plates can be effectively avoided.

[0007] In a possible implementation, the operating handle assembly includes a connecting seat and a handle body. The connecting seat is fixed to the bracket, and the lower end of the handle body is rotatably connected to the connecting seat through a second rotating shaft. One end of the second rotating shaft is integrally formed with a second connecting ear that radially protrudes from the second rotating shaft, and the second connecting ear is fixed to the outer side wall of the lower end of the handle body through a second bolt. After adopting this structure, under the action of the second rotating shaft, the lower end of the handle body can be reliably and conveniently rotatably connected to the connecting seat. In addition, since one end of the second rotating shaft is integrally formed with a second connecting ear that radially protrudes from the second rotating shaft, and the second connecting ear is fixed to the outer side wall of the lower end of the handle body through a second bolt, the axial movement of the second rotating shaft can be restricted, that is, the situation where the second rotating shaft disengages from the connecting seat and the handle body can be effectively avoided.
