Description

Power distribution tool propelling mechanism and power distribution switch cabinet Technical Field The utility model relates to power distribution equipment, in particular to a power distribution tool propelling mechanism and a power distribution switch cabinet. Background At present, the driving mode of the power distribution tool propelling mechanism mainly comprises manual driving and automatic driving. In the prior art, manual and automatic drives typically employ clutches for connection and switching. When the clutch is connected, the motor drives the movable seat to move, and when the clutch is separated, the movable seat is driven to move by a manual mode. However, the clutch has a complex structure and has reliability problems that when the clutch is damaged, the situation that both manual and electric modes cannot be driven can occur, so that the movable seat cannot move, and normal use is affected. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide a power distribution tool propelling mechanism and a power distribution switch cabinet, and solve the problem that a movable seat cannot move when a clutch is in a problem. The power distribution tool propelling mechanism comprises a frame, a movable seat arranged on the frame and a driving mechanism arranged on the frame, wherein the driving mechanism is used for driving the movable seat to move; The gear set comprises a first gear and a second gear, the first gear is connected to the screw rod in a threaded manner, the second gear is connected with the output end of the driver, and a plurality of transition gears are arranged between the first gear and the second gear; a reduction ratio exists between adjacent gears among the gear sets, and the gear sets realize reduction transmission through the reduction ratio; the driving force of the driver drives a first gear on the screw rod to rotate after being decelerated through a reduction ratio between gear sets; and a first gear sleeved on the screw rod forms rotation resistance through a reduction ratio, and the screw rod is manually driven to rotate to drive the movable seat to move along the screw rod. As a further improvement of the utility model, the movable seat is provided with a through hole, the stand is provided with a guide rod, and the guide rod is arranged in the through hole in a penetrating way; The guide rod is used for limiting the rotation of the movable seat, so that the movable seat can only linearly move along the extending direction of the screw rod. As a further improvement of the utility model, a slot is arranged at the bottom of the frame corresponding to the position of the screw rod; The slot is used for being inserted with a driving plug-in unit to drive the screw rod to rotate, and the driving plug-in unit is detachably arranged in the slot.
