Problems solved by technology

The shortcoming of prior art is: lock ring weight is big, and the rebound force when opening is strong, and crowbar is easy to slide out in installation process, causes personal safety accident
The disadvantages of the double-opening lock ring are: the installation of the lock ring takes a long time, there are many processes, and the operation is troublesome
However, these lock rings still have troublesome installation and disassembly, many procedures, and many personal safety accidents.

Embodiment 1

[0039] Such as figure 1 , figure 2 As shown, for a mine truck with a load capacity of 200 tons, the lock ring is composed of two single lock rings 1 and 2 made of 65 carbon spring steel. Among the figure, 1 and 2 are the single lock ring; 3 is the tongue cavity of the single lock ring 1; 4 is the tongue of the single lock ring 2. Such as image 3 The tongue 4 of the single-piece lock ring 2 is shown inserted into the tongue cavity 3 of the single-piece lock ring 1 . There is a gap A between the tongue 4 and the tongue cavity 3; there is a gap B between the single locking ring 1 and the single locking ring 2. Gap A and Gap B are the expansion and contraction space reserved for the lock ring, and they are also working grooves for removing the lock ring, which facilitates the installation and disassembly of the lock ring. Figure 4 The position of the lock ring is shown in the lock ring groove 5 of the rim 6 .

Embodiment 2

[0042] For mining vehicles with a load capacity of 400 tons, the lock ring is composed of three single-piece lock rings made of alloy spring steel. When installing the lock ring in this embodiment, the single lock ring 1 is placed in the lock ring groove 5 first, and the tongue 4 of the single lock ring 2 is inserted into the tongue cavity 3 of the single lock ring 1 . Then insert the tongue 4 of the third single lock ring into the tongue cavity 3 of the single lock ring 2; then insert the tongue 4 of the single lock ring 1 into the tongue cavity 3 of the third single lock ring. Press the connected lock ring in the lock ring groove 5 to complete the installation of the lock ring. When the lock ring is disassembled, take out the single lock ring 1 from the lock ring groove 5 at the gap A, and then take out the single lock ring 2 and the third single block lock ring from the lock ring groove 5 in turn, and it is completed Lock ring removed.

Abstract

The invention belongs to the tire demounting equipment for heavy vehicles, and relates to a large heavy vehicle used rim lock ring having mortise and tenon joints. The rim lock ring for large heavy vehicles in the prior art has the defects that the mounting and the demounting are complicated, many working procedures are needed, and many personal safety accidents are caused during mounting and demounting. The rim lock ring disclosed by the invention is formed by more than two identical lock ring units which have mortise and tenon structures and are connected together. A tongue cavity (3) is formed in one end of each lock ring unit, and a convex tongue (4) is arranged at the other end of each lock ring unit; each tongue cavity (3) mates with the tongue (4) of the adjacent lock ring unit; the optimum number of the lock ring units is 2-4. The rim lock ring disclosed by the invention has the advantages that the single lock rings have the same shape, so that the manufacture is easy; the mating of the mortis and tenon structures are tight, so that the locking function is good; the locking rings are convenient to mount and demount, so that the tires of the heavy vehicles are convenient to mount and demount; when the lock rings are mounted or demounted, the cooperation of many people using crowbars is not needed, the personal safety accidents are avoided, and the lock rings are safe to mount and demount.

Description

technical field [0001] The invention belongs to a load-carrying vehicle tire dismantling device, in particular to a large-scale load-carrying vehicle rim lock ring with a concave-convex groove. Background technique [0002] With the development of the world's mining industry, the production scale of various open-pit mines is increasing, and the loading capacity of super-large mining trucks is increasing. Some of them have a load capacity of more than 400 tons, and there is a tendency to gradually increase. Due to the heavy load of super-large trucks and poor road conditions, the service life of vehicle tires is short, and even new tires are damaged after 2-3 months of operation and need to be replaced. Frequent replacement of tires is an important task for the maintenance of super-large trucks. The tire of the truck is tightly connected with the rim seat through the lock ring to fix the tire on the rim. Due to the large diameter of the wheels of heavy-duty vehicles, such as...
