Kind Code:
A1
Abstract:
A trolley, comprising a trolley body, a support table (2), a hydraulic mechanism, and a control assembly. The bottom of the trolley body is provided with four wheels (1) which are in rail connection with rails (6) inside a ship cabin. Each electric traveling rail wheel (1) is connected to a motor (11), and the four motors (11) are connected in series. The support table (2) is disposed on the trolley body in rise and fall fashion, and a scissor structure (4) is disposed between the support table (2) and the trolley body. The hydraulic mechanism comprises a hydraulic cylinder (31); the hydraulic cylinder (31) is connected to the scissor structure (4) and used for driving the support table (2) to rise and fall. The control assembly is electrically connected to the motors (11) and the hydraulic mechanism, respectively. By making the support table (2) for supporting a boat to be moved to rise and fall using the hydraulic cylinder (31) and driving the rail trolley to move by means of the motors (11), the electric traveling rail trolley resolves the problem of the incapability of completing the pickup, displacement, and the placement of a boat in a transport cabin of a ship.
