Abstract

The invention discloses a hoisting device for construction and belongs to the field of hoisting and transporting machinery. The hoisting device comprises a main machine of an all-angle hoisting machine, a rotating rack (1) and a bottom rack (2), wherein the main machine of the all-angle hoisting machine comprises a gear motor (3), a hoisting arm (4), and a hoisting steel wire rope device (5); the upper part of the rotating rack (1) is connected with the hoisting arm (4); the rotating rack (1) are movably mounted on a rotating shaft (2-3) through a pair of tapered bearings (11); the rotating shaft (2-3) are positioned at the bottom rack (2); the all-angle hoisting machine further comprises a mobile device and a locking screw set (10); the mobile device comprises a dovetail groove sliding rail (6), a dovetail sliding block (7) and a transmission screw pair (8); the dovetail groove sliding rail (6) is fixedly arranged on the ground. The all-angle hoisting machine can conveniently move along the dovetail groove sliding rail, the operation range of the hoisting machine in enlarged; the possibility of toppling accidents when the hoisting machine is overloaded is effectively prevented; the hoisting machine has a good market popularization value.

Description

technical field [0001] The invention relates to the field of hoisting and transporting machinery, in particular to a building hoisting equipment. Background technique [0002] Lifting machine is a kind of machine that can transfer and change things. Due to its small size and low production cost, it plays a huge role in small building installations, factory handling, hydropower projects, etc. At present, the existing full-angle lifting machine It meets the free rotation of the boom and realizes the full-angle lifting function, but its working radius is small, and it needs to be moved frequently to meet the lifting work outside the radius, and the weight of the full-angle lifter is not small, and it is inconvenient to carry. Contents of the invention [0003] The purpose of the present invention is to aim at the present, the existing full-angle hoist meets the free rotation of the boom and realizes the full-angle hoisting function, but its working radius is small, and it nee...
