[0029] EMBODIMENT

[0030] A transport chassis of a battery replacement device, comprising a base plate 1, a first hydraulic support leg 4 is connected around the base plate 1, a sliding rail 13 is arranged at the bottom of the base plate 1, one end of the sliding rail 13 is towards the middle of the base plate 1, the other end of the sliding rail 13 is towards the long side of the base plate 1, a sliding block 12 is slidably connected on the sliding rail 13, a second hydraulic support leg 8 is arranged on the sliding block 12.

[0031] The prior art mostly uses a trailer for transportation. The trailer is a flat plate, and the lower part of the flat plate is provided with supporting legs and wheels. The trailer is installed in one body with the battery replacement device. After the battery replacement device works, the trailer cannot be separated from the battery replacement device for other purposes. Moreover, after the trailer is lifted off the ground by the supporting legs, the weight of the wheels will also increase the load of the supporting legs. The present application uses a flatbed truck to transport the bottom plate 1, which avoids the use of a trailer for transportation, which leads to the trailer being unable to be separated from the battery replacement device for other purposes. The bottom plate 1 of the present application is not provided with wheels, which can save the weight of the wheels and reduce the load of the supporting legs.

[0032] The first hydraulic supporting leg 4 supports the four sides of the bottom plate 1. Then, the position of the second hydraulic supporting leg 8 is adjusted by sliding, so that the second hydraulic supporting leg 8 moves a certain distance towards the middle of the bottom plate 1 and supports it, thereby sharing the weight of the middle of the bottom plate 1 and avoiding damage caused by the deformation of the bottom plate 1 under pressure. During transportation, the second hydraulic supporting leg 8 can slide and adjust the position along the long side of the bottom plate 1, thereby avoiding the flatbed truck, and facilitating the movement of the carrying plate of the flatbed truck to the lower part of the bottom plate 1 to place the bottom plate 1. The sliding rail 13 can be arranged along the width direction of the bottom plate 1 or inclinedly arranged, so that the sliding block 12 can move a certain distance towards the middle of the bottom plate 1.

[0033] The sliding block 12 is threadedly connected with a fixed knob 14 for abutting with the sliding rail 13. After the fixed knob 14 abuts against the sliding rail 13, the position of the sliding block 12 and the second hydraulic supporting leg 8 can be fixed, thereby avoiding the second hydraulic supporting leg 8 from sliding and colliding and being damaged during transportation.

[0034] The bottom of the bottom plate 1 is provided with a mechanical supporting leg 5. The mechanical supporting leg 5 supports the bottom plate 1, thereby avoiding the sudden falling of the transportation chassis after the first hydraulic supporting leg 4 and the second hydraulic supporting leg 8 fail, which can cause damage to the battery replacement device.

[0035] The bottom of the bottom plate 1 is provided with a containing groove 11 for placing the mechanical supporting leg 5, and the mechanical supporting leg 5 is hingedly arranged in the containing groove 11. The mechanical supporting leg 5 can be placed in the containing groove 11 by turning over, thereby avoiding the flatbed truck. After the mechanical supporting leg 5 is turned over into the containing groove 11, the mechanical supporting leg 5 is fixed in the containing groove 11 by manually setting a bolt or binding a wire, thereby avoiding the mechanical supporting leg 5 from deviating out of the containing groove 11.

[0036] The mechanical supporting leg 5 comprises an outer sleeve 501, and a lead screw 502 is threadedly connected in the outer sleeve 501 and extends from the bottom of the outer sleeve 501. Rotating the lead screw 502 to rotate the lead screw 502 out of the outer sleeve 501, thereby adjusting the extension length of the mechanical supporting leg 5, thereby supporting.

[0037] A nut 503 is fixedly sleeved on the lead screw 502 and located outside the outer sleeve 501. The nut 503 facilitates the rotation of the lead screw 502 by using a wrench or other tools.

[0038] The lower end of the first hydraulic support leg 4, the second hydraulic support leg 8 and the mechanical support leg 5 is hinged with a support pad 9. The hinged support pad 9 can make the first hydraulic support leg 4, the second hydraulic support leg 8 and the mechanical support leg 5 better support the ground.

[0039] The first hydraulic support leg 4 and the second hydraulic support leg 8 are spherically hinged with the support pad 9, which can better adapt to uneven ground, and the mechanical support leg 5 can not adopt spherical hinge because the screw rod 502 can rotate horizontally to adjust the position of the support pad 9 during adjustment, so that the support pad 9 can be deflected towards any direction.

[0040] The slide rail 13 does not protrude from the lower surface of the bottom plate 1, avoiding the slide rail 13 affecting the movement of the flat car under the bottom plate 1.

[0041] A side short edge of the bottom plate 1 is connected with two triangular support frames 2 arranged at intervals, and the two triangular support frames 2 are connected with a connecting rod 3. The triangular support frame 2 is a right triangle, and a stand is arranged on the bottom plate 1 and fixedly connected with the triangular support frame 2 to increase the support stability of the triangular support frame 2. The control equipment 10 is installed on the triangular support frame 2, and the connecting rod 3 is connected to the front end of the triangular support frame 2, which can avoid the goose neck part of the flat car.

[0042] A plurality of fixing frames 6 and mounting rods 7 are arranged on the bottom plate 1, the fixing frame 6 is used for binding a steel wire rope, the steel wire rope is fixed on the vehicle body, so as to fix the bottom plate 1 on the vehicle body, and the mounting rod 7 can be used for mounting a sign, a baffle, an indicator light and the like.

[0043] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
