The underframe 20 is provided with lock pins 21, the bracket 10 is provided with lock holes which can be matched with the lock pins, the lock holes are distributed on the lock disc 11, and the lock disc is fixed on the bracket.

A disc-shaped member 22 is fixed on the bottom frame 20, the disc-shaped member is provided with a jack 23, and a lock pin 21 is inserted into the jack 23 and inserted into a corresponding lock hole to lock the relative positions of the bottom frame 20 and the bracket 10.

In actual operation, referring to fig. 5 to 12, initially, the empty bracket 10 rotates downward to the lowest position, the movable pin 71 moves downward to the bottom end of the chute 701, and the telescopic spring 72 applies downward action to the bracket 10, so that the bracket 10 has a downward rotation tendency, and the empty bracket 10 is pressed against the ground. In this way, a worker can position the battery 60 on the stand 10 with the stand stabilized, the battery being held by the pair of holding jaws. The cover plate of the battery housing may be removed prior to the pair of jaws holding the battery.

Thereafter, the worker lifts the stand 10, and before lifting, the movable pin 71 is displaced upward to the top end of the chute 701, and the extension spring 72 exerts an upward tension on the stand 10. After that, the worker lifts the stand 10, and with the aid of the extension spring 72, can easily lift the stand 10 until the center of gravity of the battery 60 is on the same vertical line as the center of gravity of the chassis 20. The worker inserts the locking pin 21 into the insertion hole 23 and the corresponding locking hole to fix the relative position of the bracket 10 and the bottom chassis 20. The worker may perform all-round observation and maintenance of the battery 60.

After the worker overhauls the battery 60, he needs to tilt the stand 10, and the stand 10 can be slowly lowered due to the telescopic spring 72. After the top end of the stand 10 is abutted against the ground, the worker needs to displace the movable pin 71 to the bottom end of the chute 701 so that the extension spring 72 has a downward tension on the stand 10, and then the worker removes the battery from the stand 10. The empty bracket 10 does not rotate upward under the action of the extension spring 72.

As shown in fig. 2, a top end of the chute 701 is provided with a top end positioning bayonet 702, and a bottom end of the chute is provided with a bottom end positioning bayonet 703. A handle is attached to the movable pin 71. As shown in fig. 5, initially, the hollow bracket 10 rotates downwards to the lowest position, the movable pin 71 moves downwards to the bottom end of the chute 701, and the movable pin 71 is clamped into the bottom end positioning bayonet 703, so that the movable pin is positioned. The telescopic spring 72 applies a downward action to the stand 10, so that the stand 10 has a downward rotation tendency, and the empty stand 10 is pressed against the ground.

Before the worker lifts the bracket 10, as shown in fig. 7, the movable pin 71 is moved upward to the top end of the chute 701, and the movable pin 71 is locked into the top end positioning bayonet 702, so that the movable pin is positioned, and the telescopic spring 72 has an upward tension on the bracket 10.

After the worker finishes the maintenance of the battery 60, with reference to fig. 9 and 10, the worker needs to tilt the stand 10 down, and before starting to rotate the stand 10 downward, the worker removes the movable pin 71 from the top end positioning bayonet 702. After that, the worker starts to lower down the stand 10, and since the movable pin 71 can freely slide along the vertical chute 701 and the extension spring 72 has a pulling force on the stand 10, the stand 10 can be slowly lowered.

After the top end of the bracket 10 is in contact with the ground, the worker displaces the movable pin 71 to the lowest end of the chute 701 and snaps it into the bottom end positioning bayonet 703 before starting to remove the battery from the pair of jaws. Thereafter, the worker removes the battery 60 from the stand 10.

Any clamping jaw is provided with a clamping jaw cavity which is rectangular pyramid-shaped. In operation, a pair of opposed corners of the battery 60 are held by the pair of jaws, and the battery corners are mated with the jaw cavities such that the battery is stable in position between the pair of jaws and does not slip relative to the jaws.

As shown in fig. 1, the pair of clamping jaws includes a first clamping jaw 30 and a second clamping jaw 40, the bracket 10 is provided with two clamping jaw mounting ends, the first clamping jaw is pivoted on a movable rod 31, the movable rod is movably matched with one clamping jaw mounting end, and the second clamping jaw is pivoted on the other clamping jaw mounting end. The pair of clamping jaws are pivoted at the corresponding clamping jaw mounting ends through the bearings respectively, so that a worker can rotate the battery by 360 degrees during maintenance, and the battery can be overhauled in all directions.

Referring to fig. 3 and 4, a ratchet 32 is provided on the movable rod 31, a fixed block 50 is provided at the mounting end of the clamping jaw, a through hole 51 is provided in the fixed block, the movable rod is engaged in the through hole, a wedge lock 52 capable of being engaged with the ratchet is provided in the fixed block, the wedge lock is movably engaged in a barrel 53, a telescopic spring 54 is provided between the barrel and the wedge lock, a threaded rod 55 is pivoted at the tail end of the barrel, and the threaded rod is screwed on the fixed block.

Because a pair of jaws are required to grip a pair of diagonal corners of the battery 60, the battery is not laid flat when the pair of jaws grip the battery, and the position of the battery is difficult to control. To this end, a jaw of the present invention is provided on a movable bar 31 provided with ratchet teeth 32. In practice, with the rack 10 tipped, the worker holds the battery with one corner thereof engaging the jaw cavity of the second jaw 40, after which the worker pulls the movable bar 31 to bring the first jaw 30 toward the other corner of the battery and to engage the jaw cavity of the first jaw 30 with the corner of the battery. Because the movable rod 31 is provided with the ratchet 32, the ratchet is matched with the wedge-shaped locking piece 52 for use, after the clamping jaw cavity of the first clamping jaw 30 is matched with the battery angle, the wedge-shaped locking piece 52 can block the ratchet 32 from retreating, so that the movable rod 31 is limited to retreating, and the matching of the clamping jaw cavity of the first clamping jaw 30 and the battery angle is maintained. This simplifies the clamping of the battery 60 by the pair of jaws.

When the battery 60 needs to be dismounted, the worker rotates the handle 550 of the threaded rod 55, the threaded rod drives the barrel 53 to retreat, the barrel drives the wedge-shaped locking block 52 to retreat, the wedge-shaped locking block does not lock the ratchet 32 on the movable rod 31 any more, and the movable rod can move along the through hole 51, so that the first clamping jaw 30 releases the battery 60.

The through hole 51 is provided with a trapezoid groove 56, the movable rod 31 is provided with a trapezoid slide block 33, and the trapezoid slide block is matched in the trapezoid groove; the ratchet 32 and the trapezoidal slider are located on both sides of the movable bar, respectively. The trapezoidal groove 56 limits the trapezoidal slider 33 so that the trapezoidal slider can only slide along the trapezoidal groove 56, and further limits the radial position of the movable rod 31 in the through hole 51, so that the ratchet 32 can be stably matched with the wedge-shaped locking piece 52.

The foregoing is merely illustrative of the preferred embodiments of the present invention, and modifications in detail will readily occur to those skilled in the art based on the teachings herein without departing from the spirit and scope of the invention.
