Abstract

The utility model relates to lifting equipment for building, in particular to a micro crane, which comprises a motor, a hoisting mechanism and a rotating mechanism. The motor and the hoisting mechanism can be arranged at the top part of the machine frame in a rotating way; the top part of the machine column of the machine frame is provided with the rotating mechanism which can rotate for 360 degrees; and the motor and the hoisting mechanism are arranged on the rotating mechanism and can rotate around the machine column. When the micro crane is removed, the machine is horizontally arranged; the two screws of the machine frame connecting plate and the locking nuts on the flexible support rod are removed; the machine column and the arm lever are lifted; and the components integrated with the motor can be removed. If the arm lever needs to be removed, the locking nuts are loosened, and the flange is knocked upwards. If the arm lever needs to be combined, the structure which is removed together with the motor is arranged on the ground, the position of the flexible support rod is aligned, and the machine frame positioning plate and the flange are positioned. When being used, the micro crane can rotate for 360 degrees. The machine frame is integrated as the counterweight, thereby being safe and reliable.

Description

Miniature loop wheel machine

Technical field

The utility model relates to hanging device for building, refers in particular to a kind of miniature loop wheel machine.

Background technology

Present small-sized loop wheel machine is often seen in building operation, it is a kind of indispensable hanging device, but there is a very big defective in these loop wheel machines, be exactly that arm can not rotate by 360 degree, generally only revolve and turn 90 degrees, because the hoisting mechanism setting of loop wheel machine on the ground, the steel rope that elevator is used must pass through reel, frame also has the lifting of arm ability, if it is impossible doing 360 degree rotations, many rotations a bit are exactly potential safety hazard, and the loop wheel machine of this mechanism dismounting trouble, being not easy to carrying, the assembling of dismounting back is adjusted and all is difficult to return to original position.

Summary of the invention

The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of light, safe and reliable miniature loop wheel machine is provided.

The technical solution of the utility model is a kind of loop wheel machine of being made up of electrical motor, hoisting mechanism and rotating mechanism of structure, electrical motor and hoisting mechanism can be rotatably set in the top of frame, the top of the column of its mid frame be provided with one can 360 the rotating mechanism that rotates of degree, electrical motor and hoisting mechanism promptly are arranged on the rotating mechanism, and can be around the column rotation.

When the utility model is removed, put frame for sleeping in, pull down two screws of framework connecting plate, the assembly jack panel of telescopic strut lifts column, armed lever then, with electrical motor in just having descended of one, if armed lever is unloaded, unscrew jam nut, up strike flange; During combination, the electrical motor one is placed on the ground by the structure that unloads, to the position of good telescopic strut, framework connecting plate and flange are in place then earlier, can rotate by 360 degree during use, and back organic frame one is accompanied heavily, and is safe and reliable.
