Embodiment
[0024] Such as Figure 8-12 As shown, it is a structural schematic diagram of a wheel loader frame locking structure provided by the present invention, one end of the fixed rod 4 is a fixed end, and the other end is a movable end 9 . The fixed end of fixed rod 4 is connected with front vehicle frame 1, and a fixed plate 8 for fixing fixed rod 4 movable ends 9 is installed on the front vehicle frame 1, and jack two 14 are opened on fixed plate 8. The fixed end of the fixed rod 4 is connected with the front frame 1 through the pin shaft 3. Insert the pin shaft 3 after aligning the pin hole on the fixed end of the fixed rod 4 with the pin hole on the front frame 1, so that the fixed rod 4 can be close to the front vehicle frame 1 to rotate. One end of the pin shaft 3 is a larger end, and the other end is a smaller end. The smaller end is inserted into the fixed end of the front frame 1 and the fixed rod 4 in turn, and the smaller end is exposed from the fixed rod 4, and the expo...

The invention discloses a wheel loader frame locking structure. The fixed end of a fixing rod is connected with a front frame. The wheel loader frame locking structure is characterized in that a fixing board used for fixing the movable end of the fixing rod is arranged on the front frame; the fixed end of the fixing rod is connected with the front frame in a rotary mode through a hinge pin; a first inserting hole is formed in a lower hinge board of a rear frame; the movable end of the fixing rod is of a bent structure, when the movable end of the fixing rod is connected with the rear frame, the movable end penetrates through the first inserting hole, a first pin hole is formed in the portion, exposed from the first inserting hole, of the movable end, and an opened pin is arranged in the first pin hole; when the movable end of the fixing rod is fixed to the front frame, the portion, corresponding to the fixing board, of the fixing rod is provided with a protruding structure, the protruding structure is exposed from a second inserting hole of the fixing board, a second pin hole is formed in the exposed portion, and an opened pine is arranged in the second pin hole. The wheel loader frame locking structure is simple in structure and technology, convenient to operate and low in manufacturing cost.
Description
technical field [0001] The invention relates to a wheel loader frame locking structure, which belongs to the technical field of loaders. Background technique [0002] Wheel loader is a kind of engineering machinery for shoveling and loading. It is widely used in urban, transportation, water conservancy and other infrastructure constructions. At present, most of the frame locking structures of wheel loaders on the market are as follows: Figure 1-7 Shown, the front side of front vehicle frame 1 is provided with monolithic lock seat one 16, and rear side is provided with lock seat two 17, and lock seat two 17 is made up of the monolithic lock seat with interval between two pieces; 7 is provided with a monolithic lock seat 3 18; one end of the fixed rod 4 is a fixed end, and the fixed end of the fixed rod 4 is connected with the front frame 1, and the fixed rod 4 includes a connecting rod 41, and one end of the connecting rod 41 is provided with a pin Shaft hole, the both sides...
