The detachable platform supporting mechanism comprises supporting platforms 15, fixing nuts 9, fastening nuts 10, adjusting bolts 11, connecting bolts 16 and connecting plates 17, each supporting platform 15 is supported on the ground through the 4 adjusting bolts 11, each adjusting bolt 11 can adjust the length of the adjusting bolt to enable the supporting platform 15 to be always horizontal on the uneven ground, and the fastening nuts 10 are screwed down to enable the height of the supporting platform 15 to be fixed after adjustment is completed. The support platform 15 can be raised or lowered by pulling on the nut of the jack bolt 11.
The platform supporting mechanism is used for providing stable stressed support for the trolley auxiliary walking mechanism and the lateral displacement adjusting mechanism. Because the ground of the environment is covered with stones and is uneven, the lowest end of the adjusting bolt 11 is conical, so that the contact surface between the adjusting bolt and gravel is increased, and the adjusting bolt is more stable. Meanwhile, the height of the 4 adjusting bolts 11 of each supporting platform 15 can be independently adjusted according to the height difference of the ground, so that the supporting platform 15 is always kept horizontal on the uneven ground, and when the trolley moves, the height can be independently adjusted to enable one side of the supporting platform to incline, and the advancing resistance of the trolley is reduced, as shown in fig. 6. After the height adjustment is finished, the fastening nut 10 is tightened to fix the height of the supporting platform 15. Every two supporting platforms are fixedly connected through a connecting bolt 16 and a connecting plate 17. Because every driving has 8 dollies, the distance that needs the walking when the dolly of different positions shifts out is different, consequently makes a plurality of supporting platform, selects the supporting platform of different quantity to link together and carries out work according to actual need, more is convenient for install and carry.

The working process is as follows: referring to fig. 1-6, referring to fig. 2, the trolley is first lifted out of the range of the trolley support 23. Therefore, according to the distance that the trolley needs to move on the cart track 18 and the length of the supporting platforms 12, the total length of the plurality of supporting platforms 12 which are connected can be suitable for the distance needed by the replacement of the trolley, the required number of supporting platforms 12 are selected, one of the supporting platforms 12 is placed below a trolley reduction box and is tightly attached to a track sleeper, then 2 lateral displacement adjusting mechanisms are taken out, the platform clamps 3 are respectively placed at two ends of the supporting platforms 12 to clamp the side plates of the supporting platforms 12, meanwhile, the distance between the supporting platforms 12 and the track is adjusted to clamp the track clamps 1 to fix the track clamps, then, a wrench is used for rotating 4 adjusting bolts 10 to enable the height of the supporting platforms 12 to be lifted, then each adjusting bolt 10 is adjusted according to the concave-convex of the ground to enable the supporting platforms 12 to be kept horizontal, and finally, the fastening bolts 9 are screwed. Then the mobile trolley 11 is placed below the reduction gearbox in the track on the inner side of the supporting platform 12, a proper amount of backing plates 13 are added on the horizontal plate according to the vertical height between the horizontal plate and the bottom of the reduction gearbox until the mobile trolley 11 is very close to the bottom of the reduction gearbox, the backing plates 13 can not be added, then the heights of other supporting platforms 12 are adjusted to be consistent with the height of the previous supporting platform 12, then the connecting plate 14 and two adjacent supporting platforms 12 are tightly attached and fixed by the connecting bolts 13, so that the supporting platforms are connected into a whole, finally, two lateral displacement adjusting mechanisms are respectively moved to two ends of the whole supporting platform, and the cart track 18 and the supporting platform 15 are connected and fixed again by the track clamp 1 and the platform clamp 3.
Then, the trolley is detached, referring to fig. 3, the connection point 22 is detached, the trolley is separated from the traveling crane, the trolley loses balance due to self weight, the reduction gearbox falls on the movable trolley 11 tightly attached to the bottom of the reduction gearbox, and then the adjusting bolt 10 can be adjusted again to keep the wheels of the trolley horizontal. After adjustment is completed, the brake of the trolley speed reducer is released, then the trolley is pushed to move along the track direction so that the trolley moves out of the driving range, the wheels of the trolley run on the track, and the speed reducer runs on the supporting platform 12 by means of the travelling trolley 11. When the trolley moves to a preset position, the trolley can be lifted off the track.
At this time, the new trolley is hoisted and placed at the position of the original trolley on the track, and the bottom of the reduction gearbox is also placed on the movable trolley 11. The brake of the new trolley speed reducer is released, then the new trolley is pushed to move towards the travelling support 23 along the track direction to enable the trolley to enter the range of the travelling support, the wheel side of the new trolley travels on the track, the speed reducer side travels on the supporting platform 12 by means of the movable trolley 11, and when the new trolley moves to the trolley mounting position connecting point 22, the new trolley stops moving.
At this point, the mounting position of the new carriage parallel to the wheel direction has been reached, but the mounting position in the wheel direction still needs to be adjusted. Referring to fig. 4, first, 2 lateral displacement adjusting mechanisms are taken out, the rail clamps 1 are respectively placed beside two wheels of a new trolley to clamp the rail, and meanwhile, the platform clamp 3 is clamped on a side plate of the supporting platform 12 to fix the supporting platform.
