The working process of the telescopic supporting leg is briefly described as follows: when the telescopic supporting leg 22 is unfolded, the telescopic driving piece 221 drives the lifting component 222 to descend, the horizontal height of the hook 225 descends while the lifting component 222 descends, the outer support body 223 expands outwards under the action of the self gravity of the telescopic supporting leg 22, the obtuse angle of the linear connecting piece 226 is smaller, and after the outer support body 223 expands outwards to a certain degree, the buckle plate 229 is buckled with the pin shaft 2271, namely the outer support body 223, the upper support rod 227 and the buckle plate 229 form a triangular stable structure; the telescopic driving member 221 continues to drive the lifting assembly 222 to descend, while the hook 225 is limited by the limiting structure 2231 and does not continue to descend along with the top block 224, and the outer support 223 does not continue to expand outward. When the telescopic supporting leg 22 is contracted, the telescopic driving member 221 drives the lifting assembly 222 to ascend, when the lifting assembly 222 ascends to a certain degree, the top block 224 props against the hook 225 to drive the horizontal height of the hook 225 to ascend, the buckle plate 229 is separated from the pin shaft 2271, the ascending of the hook 225 drives the linear connecting piece 226, the obtuse angle of the linear connecting piece 226 is increased, one end of the upper supporting rod 227 connected with the outer supporting body 223 moves upwards, and the outer supporting body 223 retracts towards the direction close to the platform support 26.

Through the above description of the working process of the telescopic supporting leg, it can be easily found that the expansion and retraction of the telescopic supporting leg comprises two processes: firstly, the outer supporting legs of the telescopic supporting legs expand outwards/retract inwards; and secondly, the lifting component 222 lifts. The telescopic supporting legs can be expanded outwards to enable emergency equipment to be loaded onto the truck with narrow width from the self-discharging platform 2 conveniently, and in the process of truck transportation, the telescopic supporting legs 22 cannot be located outside the outline of the truck, so that the emergency equipment can be loaded onto the truck with narrow width from the self-discharging platform 2. Generally speaking, the expansion of the telescopic support legs 22 requires an additional driving device to drive, and in the telescopic support leg of this embodiment, the additional driving device is not required, which is an advantage of the telescopic support leg.

As shown in fig. 1, optionally, the mobile power supply system further comprises a sideboard truck 4 for carrying said emergency equipment from the walking dump platform 2, said sideboard truck 4 having its left side panel, right side panel and rear side panel all set down. Emergency equipment is equipped with at least threely on the loading board of self-propelled self-discharging platform 2 telescopic support foot works as telescopic support foot's quantity is when three, plummer 21 supplies the both sides of the one end of self-propelled power supply unit business turn over are equipped with respectively telescopic support foot, and the other end of plummer 21 is equipped with remaining one telescopic support foot, when the loading, breast board truck 4 follows plummer 21 supplies the one end of self-propelled power supply unit business turn over backs into the below of plummer 21. In this embodiment, the number of the telescopic support legs 22 is four, and the two sides of the two ends of the bearing platform 21 are respectively provided with the telescopic support legs 22, so that the bearing platform 21 can be supported more stably.

Referring to fig. 9 to 12, the telescopic driving member 221 may be a driving motor, a hydraulic cylinder, or the like, in this embodiment, the telescopic driving member 221 is a driving motor, and the lifting assembly 222 includes a lifting screw 2221 matched with the telescopic driving member 221. Optionally, the lifting assembly 222 further includes a speed reducer 2211 disposed on the outer support 223, and the telescopic driving member 221 is in transmission connection with the lifting screw 2221 through the speed reducer 2211.

As shown in fig. 8, an electric cabinet 261 and a platform power supply which are electrically connected are disposed on the platform support 26, the electric cabinet 261 is electrically connected with the telescopic driving element 221, and the electric cabinet 261 is used for controlling the telescopic driving element 221 to move. Emergency equipment is from self-propelled self-discharging platform 2 from taking the platform power for emergency equipment need not external power supply from self-propelled self-discharging platform 2 when using, more convenience of customers uses.

It will be readily understood that a plurality of said telescopic support legs 22 can be controlled to operate simultaneously or independently, as the skilled person can set them as desired.

Referring to fig. 9 and 10, optionally, the buckle plate 229 is rotatably connected to the outer support 223, the telescopic support leg 22 further includes a first elastic member 2212, the first elastic member 2212 connects the outer support 223 to the buckle plate 229, so that an end of the buckle plate 229 away from the outer support 223 is close to the platform support 26, and the outer support 223 has a limiting portion for limiting a rotation angle of the buckle plate 229.

In order to prevent the telescopic supporting legs from being locked when being unfolded, so that the outer supporting body 223 cannot be expanded outwards, and meanwhile, the structure of the self-walking self-discharging platform 2 of the emergency equipment is optimized, the buckling plate 229 is provided with a supporting block 2213 for supporting the platform support 26. When telescopic support leg 22 is in the state of accomodating, support block 2213 and platform support 26 support, first elastic component 2212 is in tensile state, when telescopic support leg 22 will expand, the obtuse angle of linear connecting piece 226 diminishes slightly after, first elastic component 2212 will resume deformation, support block 2213 can transmit the reaction force that comes from platform support 26 to outer supporter 223, thereby provide the initial kinetic energy of outside extension for outer supporter 223, and then reach and avoid the dead effect of card.

Go up to be equipped with spout 2272 and second elastic component 2273 on the bracing piece 227, round pin axle 2271 slidable locates in the spout 2272, second elastic component 2273 is used for driving round pin axle 2271 is in slide in the spout 2272, and is optional, spout 2272 is the camber line. When the telescopic support legs are extended outwards to the proper position, the second elastic element 2273 is used for pulling the pin 2271 into the buckle groove of the buckle plate 229, so that the triangular stabilizing structure becomes more stable. In the process of contracting the telescopic support leg 22, the force applied by the linear connecting piece 226 to the pin 2271 is greater than the elastic force of the second elastic piece 2273, so that the pin 2271 slides along the sliding groove 2272 to be separated from the buckle groove of the buckle plate 229, and the purpose of releasing the triangular stable structure is achieved, and at the moment, the second elastic piece 2273 is in a stretching state.

Optionally, the first elastic member 2212 is a tension spring; the second elastic element 2273 is a tension spring.

Optionally, the telescopic supporting leg 22 further includes a latch 2274, the upper supporting rod 227 is provided with a plurality of pin holes 2275 matched with the latch 2274, the second elastic member 2273 is connected to the upper supporting rod 227 through the latch 2274, and the position of the latch 2274 on the upper supporting rod 227 is adjustable, so that the tensioning degree of the second elastic member 2273 is adjustable.

An adjusting screw 2214 is arranged on the hook 225, and the linear connecting piece 226 is connected with the hook 225 through the adjusting screw 2214. The setting of adjusting screw 2214 can realize that there is the nod in adjusting buckle 229 orbit and round pin axle 2271 orbit to make buckle 229 and round pin axle 2271 correspond the locking on the nod position of both.

The lifting assembly 222 further includes a foldable telescopic assembly 2222, the foldable telescopic assembly 2222 is connected to the outer support 223, and the bottom of the lifting screw 2221 is connected to the foldable telescopic assembly 2222 to drive the foldable telescopic assembly 2222 to extend and retract.
