Abstract

The utility model relates to a simple hoister. A turntable (5) is positioned above an underframe (2). A suspended arm (12) is hinged on the turntable and fixedly connected with a sector plate (20). The bottom of the turntable is fixed with a mandrel (3) which is inserted into a mandrel sleeve (4) which is fixed to the upper part of the underframe. The utility model has the advantages of simple and compact structure and convenient use. The suspended arm can rotate in 360 DEC, and both the length and the angle of the suspended arm can be adjusted.

Description

Simple and easy gig

Technical field

The utility model belongs to the gig field that promotes weight.

Background technology

Promoting at present weight has diversified simple and easy elevating gear, and what have uses electrical motor, and what have uses combustion engine, and they respectively have advantage, are suitable for respectively using under the different occasions; But the parts that have are more, volume dislikes big, the underaction that has, can not be with arbitrarily angled rotation, and the operation that also has is cumbersome, not as people's will, and suchlike deficiency makes people wish the simple and easy gig that has structure better.

Summary of the invention

The technical problems to be solved in the utility model be make simple and easy lifting function arbitrarily change angle, parts still less, more convenient operation is flexible.

The utility model solves the problems of the technologies described above with following technical scheme: rotating disk 5 is positioned at underframe 2 tops, and arm 12 is hinged on the rotating disk, captives joint with quadrant 20, and the rotating disk bottom is fixed with axle 3, and axle is inserted in the axle cover 4 that is fixed on underframe top.Simple and easy gig of the present utility model is simple and compact for structure, can be used in any place that power supply is arranged, arm can rotate by 360 degree, and length of boom and angle all can be regulated, need not brake and can guarantee that also weight can be parked on any height with security and stability, uses very convenient.

The specific embodiment

Rotating disk 5 is positioned at underframe 2 tops, and its bottom is fixed with axle 3, and axle is inserted in the axle cover 4 that is fixed on underframe top; Arm 12 is hinged on the rotating disk, arm is captiveed joint with quadrant 20, a plurality of pin-and-holes are arranged on the quadrant, being fixed on simultaneously has radius stay 18, single phase motor 10, a worm-gear speed reducer 7 on the rotating disk, there is belt pulley 6,9 to be connected between electrical motor and reductor with belt 8, reel 14 is bearing on the worm-wheel shaft and supporting base 15 of reductor, and lifting rope 17 1 ends are fixed on the reel, and the other end is walked around pulley 11 and is connected with suspension hook 16.4 iron hoops 1 are captiveed joint with 4 pin of underframe respectively, and two coaxial iron hoops are one group, the parallel axes of two groups of iron hoops.Earlier two straight-bars are passed two groups of iron hoops respectively before gig uses, press the weight equalizer used with counterweight such as sandbag etc. on the straight-bar.When pulling two-direction switch 19 motor just changeed, by belt, drop-gear box reel is rotated, furl lifting rope, the weight that hangs on the suspension hook is sling; Weight is transferred during the motor counter-rotating.Gig in use, the available artificial rotating disk rotation that arbitrarily promotes, arm is corner thereupon, weight can forward the orientation that needs to.Because the latching characteristics of worm and gear transmission, gig can be exempted braking mechanism, and complete machine is compacter.When the rod member more than two joints or two are saved connected into arm with pin 13 and corresponding pin-and-hole, length of boom was adjustable.A plurality of pin-and-holes are arranged on the quadrant, in the time of regulating the vertical angle of arm, take off the pin 21 on the radius stay, when arm is transferred to required angle again on the pin, boom angle is retightened.

Claims

1, a kind of simple and easy gig, underframe, electrical motor, reductor, reel, arm etc. are arranged, it is characterized in that rotating disk (5) is positioned at underframe (2) top, arm (12) is hinged on the rotating disk, arm (12) is captiveed joint with quadrant (20), the rotating disk bottom is fixed with axle (3), and axle is inserted and is fixed in the axle cover (4) on underframe top.
