Description

Technical Field

[0001] This utility model relates to the technical field of electric bus maintenance equipment, and in particular to an electric bus maintenance operation platform. Background Technology

[0002] When electric buses are used for a long time, it is necessary to inspect and maintain the windshield wipers, headlights and other parts of the electric buses to ensure their normal operation. Therefore, the maintenance platform can be placed on the track, and employees can stand on the platform to inspect and maintain the electric buses.

[0003] The existing maintenance platform is placed on the track and uses rollers to control the maintenance platform to move closer to the front of the electric train for maintenance.

[0004] However, when using the maintenance platform to maintain electric trains, the lack of a device to restrain the rollers makes it easy for the maintenance platform to detach from the track while moving on it, which can damage the maintenance platform. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this utility model proposes an electric bus maintenance platform. A cover plate allows the storage slot to be opened. A handwheel drives a rotating shaft, which, through the meshing connection between bevel gear one and bevel gear two, synchronously rotates with the drive shaft. Furthermore, through the meshing connection between bevel gear three and bevel gear four, two threaded rods synchronously rotate with the drive shaft. Two threaded sleeves located at the two threaded sections of the threaded rods move away from each other along the threaded rods. Through the movable connection between the hinge block and the long slot, the connecting column stored below the maintenance platform can be moved closer to the track through the hinged connection between the hinge rod and the hinge block, until the rollers abut against the side of the track. This prevents the four rollers at the bottom of the maintenance platform from detaching from the track.

[0007] To achieve the above objectives, this utility model proposes an electric bus maintenance platform, including a track. A maintenance platform for moving along the track is disposed above the track. An auxiliary device for securing the maintenance platform to the track is disposed within the maintenance platform. The auxiliary device includes two auxiliary components movably connected to the maintenance platform for assisting in securing the platform to the track. Two adjustment components are disposed within the maintenance platform for driving the two auxiliary components to move in opposite directions. A connecting component is disposed within the maintenance platform for driving the two adjustment components to rotate synchronously. A driving component for driving the connecting component to rotate is disposed above the connecting component.

[0008] In addition, the electric bus maintenance platform proposed above in this application may also have the following additional technical features:

[0009] Specifically, the bottom of the maintenance platform is provided with a long slot for placing the adjustment component, and the top of the maintenance platform is provided with a storage slot for placing the drive component. A cover plate for sealing the storage slot is movably connected inside the storage slot. The bottom of the maintenance platform is provided with four rollers for driving the maintenance platform to move along the track.

[0010] Specifically, the drive assembly includes a rotating shaft that passes through the storage slot for rotation, a handwheel for driving the rotating shaft to rotate is fixedly installed at the top end of the rotating shaft, and a bevel gear for driving the connecting assembly to rotate is fixedly installed at the bottom end of the rotating shaft.

[0011] Specifically, the connecting assembly includes a drive shaft disposed within the maintenance platform for rotation, a second bevel gear disposed on the shaft body for meshing with a first bevel gear, and a third bevel gear fixedly mounted at the left and right ends of the drive shaft for driving two adjusting assemblies to rotate synchronously.

[0012] Specifically, the adjusting assembly includes a threaded rod disposed in a long slot for rotation, and a bevel gear four for meshing with bevel gear three is disposed in the middle of the threaded rod.

[0013] Specifically, the auxiliary component includes a threaded sleeve plate disposed in a long slot for threaded connection with a threaded rod, and a hinged rod is movably connected to the bottom end of the threaded sleeve plate.

[0014] Specifically, a hinge block for rotation is movably connected within the long groove. A connecting column is fixedly installed at the bottom end of the hinge block. A hinge plate for hinged with the hinge rod is fixedly installed on the column body of the connecting column. A connecting rod is fixedly installed at the bottom end of the connecting column. A roller for moving along the track is provided at the bottom end of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up drive components, connection components, adjustment components, and auxiliary components, when the electric train needs to be inspected, the four rollers at the bottom of the maintenance platform can be placed on the track; the storage slot can be opened through the cover plate; the rotating shaft can be rotated by the handwheel, and the rotating shaft can be synchronously rotated with the drive shaft under the meshing connection between bevel gear one and bevel gear two; under the meshing connection between bevel gear three and bevel gear four, the two threaded rods can be synchronously rotated with the drive shaft; the two threaded sleeves located at the two threads on the threaded rods move away from each other along the threaded rods, and under the movable connection between the hinge block and the long slot, the connecting column stored under the maintenance platform can be moved closer to the track under the hinged connection between the hinge rod and the hinge block until the rollers abut against the side of the track; thus, the four rollers at the bottom of the maintenance platform can be prevented from detaching from the track.
