[0024] The effect achieved by the entire embodiment 1 is that when the wheel 7 is disassembled, the lever 15 is pushed to make the slide seat 11 slide along the slide groove 10, so that the telescopic rod 12 and the return spring 13 are squeezed and begin to shrink, and at the same time the slide seat 11 drives the plug post 14 to leave the slot 9 on the plug post 8, thereby releasing the limit fixation of the wheel 7, and then the wheel 7 is slid and removed along the locking seat 6, and the operation is convenient and quick. When the wheel 7 is installed, the compression elastic force of the return spring 13 is utilized to make the plug post 14 elastically plugged into the slot 9, so that the plug post 14 and the slot 9 do not slide relative to each other, which is convenient for the later disassembly and maintenance operations of the wheel 7.

[0025] Example 2: Figure 1 - Figure 5 As shown, the buffer shock absorbing mechanism 4 includes a placement groove 401, which is arranged on the inner side of the installation box 1, a shock absorbing spring 402 is fixedly connected in the placement groove 401, a movable block 403 is slidably connected in the placement groove 401, one side of the movable block 403 is fixedly connected to the reinforcement box 2, a damper 404 is installed on the inner side of the installation box 1, a reinforcing rib 16 is fixedly connected to the inner side of the reinforcement box 2, a fixed sleeve 17 is fixedly connected to the end of the reinforcing rib 16, a bearing 18 is fixedly connected in the fixed sleeve 17, the rotating shaft 3 is installed in the bearing 18, a protective cover 19 is provided at one end of the locking seat 6, a groove 20 is opened at one end of the locking seat 6, a protrusion 21 is fixedly connected to one end of the protective cover 19, and the groove 20 matches the protrusion 21.

[0026] The effect achieved by the entire embodiment 2 is that, by providing the buffer shock absorbing mechanism 4, when the oilfield special vehicle encounters a bumpy road section, the vibration of the wheel 7 drives the vibration of the rotating shaft 3, the vibration of the rotating shaft 3 drives the vibration of the reinforcement box 2, the vibration of the reinforcement box 2 drives the movable block 403 to move up and down in the placement groove 401, the movable block 403 moves up and down to drive the shock absorbing spring 402 to contract, the shock absorbing spring 402 contracts to buffer the vibration, and at the same time, under the damping action of the damper 404, it plays a role of buffering and shock absorbing, avoiding excessive vibration from being transmitted to the oilfield special vehicle, with high comfort, and then when the oilfield special vehicle encounters a bumpy road section, the vibration of the wheel 7 drives the vibration of the rotating shaft 3, the vibration of the reinforcement box 2 drives the movable block 403 to move up and down in the placement groove 401, the movable block 403 moves up and down to drive the shock absorbing spring 402 to contract, and the shock absorbing spring 402 contracts to buffer the vibration, and at the same time, under the damping action of the damper 404, it plays a role of buffering and shock absorbing, avoiding excessive vibration from being transmitted to the oilfield special vehicle, with high comfort, and then when the oilfield special vehicle encounters a bumpy road section, the vibration of the wheel 7 drives the rotating shaft 3 to vibrate, and the vibration of the reinforcement box 2 drives the movable block 403 to move up and down in the placement groove 401, and the movable block 403 moves up and down to drive the shock absorbing spring 402 to contract, and the shock absorbing spring 402 contracts to buffer the vibration. When the vehicle stops, the weight of the vehicle acts on the rotating shaft 3, the reinforcing ribs 16 support the rotating shaft 3, and the reinforcement box 2 supports the reinforcing ribs 16. At the same time, the rotating shaft 3, the reinforcing ribs 16 and the reinforcement box 2 are all made of high-strength alloy steel material, which has excellent impact resistance and wear resistance, can withstand a high load of 120T, can prevent the weight of the vehicle from bending the driven bridge, and reduce losses. Then, by inserting the protrusion 21 on the protective cover 19 into the groove 20, the locking seat 6 and the protective cover 19 are snap-fitted and installed together, which is convenient for protecting the components on the locking seat 6.

[0027] Working principle: During use, when the oilfield special vehicle encounters a bumpy road section, the vibration of the wheel 7 drives the vibration of the rotating shaft 3, the vibration of the rotating shaft 3 drives the vibration of the reinforcement box 2, and the vibration of the reinforcement box 2 drives the movable block 403 to move up and down in the placement groove 401, and the movable block 403 moves up and down to drive the shock-absorbing spring 402 to contract, and the shock-absorbing spring 402 contracts to buffer the vibration. At the same time, under the damping action of the damper 404, it plays a role in buffering and shock absorption, avoiding excessive vibration from being transmitted to the oilfield special vehicle, and the comfort level is high. When the oilfield special vehicle stops driving, the weight of the vehicle acts on the rotating shaft 3, the reinforcing ribs 16 support the rotating shaft 3, and the reinforcement box 2 supports the reinforcing ribs 16, which can prevent the weight of the vehicle from bending the driven axle and reduce losses. When the wheel 7 is to be disassembled, a pulling force is first applied to the protective cover 19 to separate the protrusion 21 on the protective cover 19 from the groove 20, thereby releasing the protection of the components on the locking seat 6, and then the lever 15 is toggled to make the slide seat 11 slide along the slide groove 10, so that the telescopic rod 12 and the return spring 13 are squeezed and begin to shrink. At the same time, the slide seat 11 drives the plug post 14 to leave the slot 9 on the card post 8, thereby releasing the limit fixation of the wheel 7, and then the wheel 7 is slid and removed along the locking seat 6. The operation is convenient and quick. When the wheel 7 is installed, the compression elastic force of the return spring 13 is utilized to make the plug post 14 and the slot 9 elastically plugged, so as to avoid relative sliding between the plug post 14 and the slot 9, which is convenient for the later disassembly and maintenance operations of the wheel 7.
