Technical Field

The invention relates to the field of off-highway vehicle tire rims and lock ring accessories thereof, in particular to a split quick-change rim and a lock ring for conveniently and quickly disassembling and assembling ultra-large type wheel vehicle tires.

Background

In the mining and construction of off-highway vehicles, particularly large open pit mines, large construction vehicles are widely used because of their relatively large payload. The tire of the heavy-duty vehicle is tightly contacted with the seat ring and the wheel rim through the locking ring, and the tire is fixed on the wheel rim. The new tire is generally damaged and needs to be replaced after 2-3 months of operation due to bad working conditions. Frequent tire replacement is an important and dangerous task for the maintenance of very large vehicles. The important reason for the difficulty in removing the tyre is the difficulty in removing and installing the lock ring, the diameter of the tyre of the ultra-large heavy-duty vehicle is up to 4.27m and is about 5.7 tons, and the weight of each lock ring is increased, and the weight of each lock ring is 50-65 Kg. When dismouting at every turn, need many people to rely on the manpower to open the lock circle, it is hard to waste time and energy, dismouting difficulty, and the dismouting is careless moreover, and the huge elasticity of lock circle can also endanger personal safety.

Aiming at the problems, the conventional product in the international market adopts a double-opening locking ring, when the double-opening locking ring is horizontally installed on a mine car, because the center of a rim is more than 2 m high from the ground, the space of an operation environment is limited, when the double-opening locking ring is installed, half of the locking ring with an opening is firstly placed in a locking ring groove on a rim body, and the other half of the locking ring needs to be lifted by two persons and placed in the locking ring groove of the rim from the lower part of the rim body, and then the locking ring is fixed by one person through a connecting plate and screws. When the lock is disassembled, three persons are required to operate the lock, and the lower half-opening lock ring can be broken on the ground without paying a little attention, so that the safety of the person is damaged or endangered. These problems are particularly difficult, cumbersome, inefficient and dangerous to assemble and disassemble the lock ring close to the inner side of the vehicle body for tires having two rows arranged side by side.

In addition, the pin hole 13 is opened at the position of the notch 11 near the end of the circular arc-shaped locking ring 1, and the positioning holes 12 are arranged at intervals inside the pin hole 13.

In addition, the pin 14 is a quincuncial cylindrical pin, and the positioning piece 15 is a bolt.

In addition, the notch 11 is a U-shaped notch.

In addition, the connecting plate 2 is an arc-shaped connecting plate, and the slot 21 is a long waist-shaped slot.

In addition, the left side and the right side of the connecting plate 2 are also provided with a through hole 22 and a concentric threaded hole 23 in the vertical direction, and the connecting plate 2 is connected with the mounting tool 3 through the through hole 22 and the concentric threaded hole 23.

In addition, the mounting tool 3 includes a base plate 31, a handle assembly 32 is connected to the base plate 31, two side plates 33 extending downward are further provided on the base plate 31, the side plates 33 are disposed on two ends of the base plate 31 on the same side or different sides (the case of the different side is not shown in the drawing), a bottom plate 34 parallel to the base plate 31 is further provided on the side plates 33, a clamping groove 35 is formed among the base plate 31, the side plates 33 and the bottom plate 34, and the clamping groove 35 is clamped by the connecting plate 2 in a matching manner.

In addition, the bottom plate 34 extends into the slot 21, and the side plate 33 and the base plate 31 contact the link plate 2 to sandwich the link plate 2.

The base plate 31 and the bottom plate 34 are provided with coupling holes 36, and the base plate 31 and the coupling plate 2 are fastened by inserting bolts 37 into the through holes 22 and the coupling holes 36.

As shown in fig. 8, the handle assembly 32 includes a base 323 vertically disposed at the center of the base plate 31, and a grip 327 vertically disposed on the base 323 is transversely installed.

As shown in fig. 9, the handle assembly 32 includes a connecting base 324 vertically disposed at the center of the base plate 31, a connecting rod 325 disposed above the connecting base 324 and parallel to the base plate, and handles 327 mounted on the left and right sides of the connecting rod 325.

As shown in fig. 10, the handle assembly 32 includes a contoured grip defined by a plate 326 disposed on the base plate 31.

As shown in fig. 11, the mounting tool 3 includes a base plate 31, a connection hole 36 is provided in the base plate 31, and a bolt 37 is inserted into the through hole 22 and the connection hole 36 to fasten the base plate 31 and the connection plate 2.
