Abstract

The invention relates to a moveable type hand-operated elevator. The moveable type hand-operated elevator consists of a fixed ladder frame and an elevator frame, wherein the fixed ladder frame consists of a fixed frame body, a transfer big wheel, a ratchet wheel, an operating crank, a moveable small wheel, a bearing foot, a sliding way, a hoisting pulley and a pedal cross rod; the elevator frame consists of a lifting frame body, a pedal cross rod, a standing pedal, a sliding rod, a supporting pulley, a safe protective chain and a safe protective guard; a lifting steel wire rope and a safe lock chain are arranged between the fixed ladder frame and the elevator frame. When the moveable type hand-operated elevator is used, the operating crank is operated by one hand, so that the lifting frame body is ascended or descended; during long-distance transfer, the elevator can be put down and the transfer big wheel is touched down; during short-distance motion, the moveable small wheel is moved for adjustment and a screw rod of the bearing foot is rotated to be touched down after in place. The elevator is convenient to transfer and simple to ascend and descend without power, safe and reliable, convenient to ascend and descend, simple to process and low in cost and saves time and labor.

Description

technical field [0001] The invention relates to a mobile hand lift. Background technique [0002] Substation maintenance requires climbing operations, and various existing ladders have various deficiencies; Chinese patent: CN201786237U, an elevator, discloses a herringbone elevator, and its disadvantage is that there is no standing platform, and the operation is inconvenient; CN202054588U GW-6 Knife gate overhaul maintains the hydraulic lifting type platform, the cost is high, and it is inconvenient for personnel to go up and down. If people stand on the platform to lift up and down, the safety is poor; Suitable for substation use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a mobile hand lift. [0004] In order to realize the above object, the technical scheme of the present invention is: [0005] A mobile hand-operated elevator, which is composed of a fixed ladder frame and an...
