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

The movable hand rotated lift
Technical field
The present invention relates to a kind of movable hand rotated lift.
Background technology
Station needs ascend operation, and there are various deficiencies in existing all kinds of ladders; Chinese patent: CN201786237U lift discloses a kind of herringbone lift, and its shortcoming is the platform of not standing, and operation is inconvenient; The hydraulic elevation type platform is safeguarded in the overhaul of CN202054588U GW-6 disconnecting link, and cost is high, and personnel are inconvenient up and down, if the people stands in lifting on the platform, poor stability; CN200999586Y lift, CN102030294A pushing trolley type manpower-driven combined shear fork lifting ladder raise highly limited, are not suitable for transformer station and use.
Summary of the invention
Purpose of the present invention overcomes deficiency of the prior art exactly, and a kind of movable hand rotated lift is provided.
Technical scheme of the present invention is to achieve these goals:
A kind of movable hand rotated lift, by fixedly ladder and lifting ladder form, it is characterized in that: fixedly ladder is by fixing bracket body (1), shift bull wheel (2), ratchet (3); rocking handle (4); mobile steamboat (5); front load pin (6); rear load pin (7); slideway (8); lifting pulley (9); foot-operated cross bar (10) forms; the lifting ladder is by lifting frame body (11); foot-operated cross bar (10); the pedal of standing (12); slide bar (13); hold up pulley (14); safe protection chain (20); safety guide rail (21) forms; lifting wire rope (15) is fixedly arranged between ladder and the lifting ladder, safe chain (19) is fixedly arranged between ladder and the lifting ladder.
Hand rocking handle (4) lifting frame body (11) will raise or descend during use, long distance shifts can fall this lift with shifting bull wheel (2) push-and-pull, short-distance movement moves adjustment by mobile steamboat (5), the screw rod of the forward and backward load pin of the rear rotation that puts in place (6,7) lands anti-skidding.
The present invention's beneficial effect compared to existing technology is:
Convenient transfer, lifting is simple, need not power, and is safe and reliable, easy for going up and down, time saving and energy saving, and processing is simple, and is with low cost.
