[0044] As Figures 1 to 14 shown, this embodiment discloses a power battery maintenance platform, including a frame 1. One side inside the frame 1 is provided with an accommodation cavity 101. A support plate 10 for supporting the battery is arranged in the accommodation cavity 101.

The chain assembly 3 is of an open structure; the curtain panel assembly 2 is arranged in the open structure of the chain assembly 3. The two ends in the width direction of the curtain panel assembly 2 are respectively connected to the two sets of chain assemblies 3, and the two ends in the length direction of the curtain panel assembly 2 are respectively connected to the two ends of the open structure of the chain assembly 3 to form an annular structure surrounding the outer periphery of the accommodation cavity 101; the two ends of the rolling curtain driving assembly 4 are respectively in transmission connection with the two sets of chain assemblies 3 to drive the chain assembly 3 to perform a forward movement action or a reverse movement action.

[0046] The curtain panel assembly 2 includes a plurality of curtain panels 201 and a plurality of groups of guiding and fitting members; the curtain panels 201 are arranged in a rectangular plate shape. One side in the width direction of the curtain panel 201 is bent a part towards the bottom end of the adjacent curtain panel 201 to seal the gap between the adjacent curtain panels 201, improving the sealing effect of the curtain panel assembly; the plurality of curtain panels 201 are arranged in sequence along the width direction of the curtain panel 201. Both ends in the length direction of the curtain panel 201 are connected with guiding and fitting members and are connected to the chain assembly 3 through the guiding and fitting members; the plurality of groups of guiding and fitting members are arranged at equal intervals along the width direction of the curtain panel 201.

[0047] Through the pin connection design of the two positioning fasteners in the guiding and fitting members, relative rotation actions can be performed between two adjacent curtain panels under the action of the pin shaft. Finally, the curtain panel assembly forms an overall structural effect in which adjacent guiding and fitting members are connected through curtain panels and adjacent curtain panels are connected through guiding and fitting members. When the chain assembly moves, only one end of this overall structure needs to be pulled to drive the entire curtain panel assembly to move; when the curtain panel assembly is in the open state, the curtain panel assembly is pulled by the chain assembly to the bottom of the accommodation cavity and one side of the accommodation cavity, and it will not cause any obstruction to the top of the accommodation cavity. In case of a fire, the chain assembly quickly pulls the top of the curtain panel assembly to move, so that the curtain panel assembly covers and blocks the top of the accommodation cavity to prevent the spread of fire.

[0048] The curtain panel assembly 2 further includes a first support guide rail 206, a second support guide rail 208, and an arc-shaped turning guide rail 207.

[0049] The rolling curtain drive assembly 4 includes a rolling curtain motor 401, a driving shaft 402, and a driving sprocket 403. The rolling curtain motor 401 is fixedly connected to the frame 1. The driving shaft 402 is rotatably connected to the frame 1 and is in transmission connection with the rolling curtain motor 401. An angle sensor is arranged on one side of the rolling curtain motor 401 to monitor its rotation angle through a gear structure.

Both ends of the transmission chain 301 are respectively connected to the guiding and cooperating parts at both ends in the length direction of the curtain panel assembly 2.

[0051] When the chain assembly is working, the rolling shutter motor drives the driving shaft and the driving sprocket to rotate, so that the two sets of chain assemblies move in one direction at the same time, and the curtain plate assembly connected to the chain assembly opens or blocks accordingly; when the chain assembly moves, the transmission chain slides and guides in the track groove of the chain guide track, and when the curtain plate assembly moves, the sliding wheel is supported and guided by the top of the first supporting guide rail, the outer arc edge of the arc-shaped steering guide rail, and the top of the second supporting guide rail, so that the curtain plate assembly moves smoothly, thereby achieving the protective effect of the rolling shutter mechanism.

[0052] The rolling shutter mechanism also includes a ratchet tensioning assembly 5 for adjusting the tension of the transmission chain 301; the ratchet tensioning assembly 5 includes a tensioning spring 502, a tensioning rope 503, and a ratchet tensioner 501, one end of the tensioning spring 502 is connected to the frame 1, and the other end of the tensioning spring 502 is connected to the ratchet wheel shaft arranged in the middle of the ratchet tensioner 501 through the tensioning rope 503; one end of the ratchet tensioner 501 is connected to the pin shaft of the frame 1, and the other end of the ratchet tensioner 501 is provided with a tensioning wheel 504 and limits the transmission chain 301 between the tensioning wheel 504 and the ratchet wheel shaft.

[0053] The ratchet tensioner can be used to adjust the length of the tension rope, so that the tension spring is in a rope-pulling state. Under the tensile elasticity of the tension spring, the ratchet tensioner will move the transmission chain a certain distance in the direction of the tension spring, so that the transmission chain remains in a tensioned state, but will not affect the normal rotation of the transmission chain.

[0054] The pulling mechanism 6 includes two groups of lifting components symmetrically arranged on the inner walls on both sides of the width direction of the accommodating cavity 101, and a pulling power component for driving the two groups of lifting components to move; the lifting component includes a first guide wheel 601, a second guide wheel 602, and a lifting rope 605.

The middle part of the lifting rope 605 is connected to the pulling power component, and the two ends of the lifting rope 605 are respectively guided downward by the first guide wheel 601 and the second guide wheel 602 and then connected to the edge of the support plate 10.

[0055] The pulling power assembly includes a winch 606, a power pulling rope 607, a third guide pulley 603, and a fourth guide pulley 604. There are two sets of the third guide pulley 603 and the fourth guide pulley 604, and the two sets of the third guide pulley 603 and the fourth guide pulley 604 are respectively arranged corresponding to the two lifting assemblies; the fourth guide pulley 604 is arranged on the side of the second guide pulley 602 away from the first guide pulley 601, and the third guide pulley 603 is arranged below the fourth guide pulley 604, and both of them are rotatably connected to the frame 1; the winch 606 is fixedly connected to the bottom end of the frame 1, the middle part of the power pulling rope 607 is wound around the outer side of the roller of the winch 606, and both ends of the power pulling rope 607 are fixedly connected to the middle part of the lifting rope 605 in the corresponding lifting assembly after being guided by the two sets of the third guide pulley 603 and the fourth guide pulley 604.

[0056] When the winch performs the winding and rotating action, it will drive both ends of the power pulling rope to perform the stretching action together. Both ends of the power pulling rope will respectively pull the middle parts of the lifting ropes in the two lifting assemblies to move, so that both ends of the lifting rope will smoothly lift the pallet under the action of the first guide pulley and the second guide pulley. Since the stretching amounts of both ends of the power pulling rope are the same, the lifting heights of the ends of the lifting ropes in the two lifting assemblies for the pallet are exactly the same, so that the pallet can be smoothly lifted while maintaining a horizontal state. When it is necessary to lower the pallet, just reverse the winch;

[0057] Maintenance personnel can adjust the height of the pallet according to their own needs, which is convenient for people to repair the battery above the pallet.
