The invention discloses an overhead hoist for a construction site. The overhead hoist comprises a machine enclosure and a bent frame, wherein the two sides of the inner wall of the machine enclosure are fixedly equipped with first slide rails through rivets; the first slide rails are in sliding connection with a slide block; one side of the slide block is fixedly equipped with a lifting rod through a bolt; the other end of the lifting rod is welded on a chain belt; the two sides of the machine enclosure are fixedly equipped with fixed rods through nuts and bolts; the other ends of the fixed rods are equipped with bearings; gears are arranged on the outer parts of the bearings in a sleeving mode; the chain belt sleeves outside the gears; one side of the chain belt is welded with a pushing rod; and the other end of the pushing rod is connected with a first linkage rod through a shaft. The slide block, the lifting rod, the pushing rod and the like are arranged, so that a placing box is automatically fixed in a rising process, and therefore, degree of automation is high, and manual fixing time is shortened; and a clamping hand, the first linkage rod, a second linkage rod, and the likeare arranged, so that stationarity of the device is strong; and when a steel wire rope lifts an object, the bottom and the two sides of the object are fixed.
Description
technical field [0001] The invention relates to the technical field of lifting devices, in particular to a lifting device for a construction site. Background technique [0002] Lifting machine is a kind of machine that can transfer and change objects. It is divided into rotary arm type lifting machine, mobile lifting machine, straight type lifting machine and full-angle type. On the construction site, some objects with large volume and weight It is difficult to carry by hand, and it is necessary to use a hoist to carry it. The hoist is indispensable on the construction site. The hoisting devices on the market have a low degree of automation and poor fixation, and the objects transported by them may fall and hurt the staff. Most of the hoisting machines on the market move up, transport materials, and the process of descending is relatively cumbersome. [0003] Lifting device, authorized patent number: CN 106144876 A. In this invention, lifting lugs are provided at both ends ...
