The embodiment of the invention provides a lifting device which comprises a portal-shaped frame; inwards-opened chutes are arranged in a left frame and a right frame of the portal-shaped frame; two ends of a support frame are inserted into the inward chutes of the portal-shaped frame and can move up and down along the chutes; a motor-driven mechanism is arranged at the rear part of the portal-shaped frame and used for driving a vertical screw rod to move up and down, wherein the vertical screw rod extends along a vertical direction, one end of the vertical screw rod passes through the motor-driven mechanism, and the other end of the vertical screw rod is fixedly connected with a stretching mechanism; the left end and the right end of the stretching mechanism are provided with two chain wheels, wherein one ends of two chains are fixed on an upper beam of the portal-shaped frame, and the other ends of the two chains respectively and sequentially bypasses the left chain wheel and the right chain wheel of the stretching mechanism from the lower side, bypasses two fixed chain wheels fixed on the portal-shaped frame from the upper side and extends downwards and are fixed on the support frame; and a hoisting mechanism is arranged in front of the support frame.
Description
technical field [0001] The invention belongs to the field of power systems, and in particular relates to a lifting device applied to a 10Kv center-mounted switch cabinet handcart. Background technique [0002] The 10KV central switchgear has been widely used in the power system. In the operation of the central switchgear, a switch handcart is required, but the weight of the switch handcart is generally 300-400kg. The existing lifting device of the switch trolley cannot lower the switch trolley from the switch cabinet to the ground due to design reasons. When the switch trolley reaches a position 5-10 cm above the ground, the switch trolley needs to be manually lifted down , due to the large size and heavy weight of the switch handcart, it takes 5-6 people to work together to complete the operation of lifting the switch handcart to the ground, and the whole process is time-consuming and laborious. Contents of the invention [0003] In view of this, the object of the presen...
