Abstract

The invention relates to a small movable crane, which comprises a hoisting device, a counterweight device, a movable pedestal, leading screw supports, and support assemblies. A Y-shaped hoisting hanger of the hoisting device comprises an upper support and a lower support, wherein each end of the upper support is provided with a fixed pulley; the bottom of the lower support is fixed to a rotating shaft, which is inserted into a rotating seat. The rotating seat is fixedly mounted on the center of the movable pedestal; and the counterweight device is arranged at one side of the lower support of the hoisting hanger and is provided with a hand-operated capstan. A steel wire rope is transited via two fixed pulleys, and one end of the steel wire rope is provided with a hook. Every two of the four leading screw supports are symmetrically arranged at front and rear sides of the inner sides of two frames of the movable seat; every two of the four support assemblies are symmetrically arranged at front and rear sides of the outer sides of two frames of the movable seat; and each corner of the movable seat is provided with an omni-directional wheel. The small movable crane has advantages that the crane is small, exquisite, light and convenient, is flexible to move, and is safe and reliable; a large amount of physical power is saved for a maintenance person; the maintenance speed is greatly improved; and an emergency rescuing function of a reaction pool is provided.

Description

technical field [0001] The invention relates to a movable hoisting device which is used in a narrow space and needs to change positions frequently, in particular to a movable small hoisting machine used in the reaction tank of a sewage plant. Background technique [0002] At present, there are generally multiple reaction tanks in sewage plants, with a depth of about 8 to 9 meters. The main equipment in each tank includes a set of decanters, a set of excess sludge pumps, and a set of aeration rows. Any problem with a set of equipment must be drained, and a temporary pump needs to be erected during the treatment. Once the drainage work in the reaction tank needs to be carried out, it is necessary to organize maintenance personnel to carry the temporary pump, and use hemp rope to gradually send the pump body into the water along the edge of the reaction tank. Since the weight of the water pump itself is relatively large, it will cost a lot of money during this process. It is a...
