Electric single-beam bridge-type travelling crane for draining pump room

Abstract

The invention discloses an electric ingle-beam bridge-type travelling crane for a draining pump room and belongs to the field of draining. According to the electric ingle-beam bridge-type travelling crane, when a lifting rope is broken, a lifting hook is not prone to directly falling off so as to reduce safety accidents. According to the technical scheme of the electric ingle-beam bridge-type travelling crane for the draining pump room, the electric ingle-beam bridge-type travelling crane comprises a beam, supports supported at the two ends of the beam, an electric hoist connected with the beam in a slippage mode and the lifting hook connected with the electric hoist through the lifting rope. A rotary disc is rotatably connected to the electric hoist, the axis of the rotary disc is horizontally arranged, and a pulling rope is twined on the rotary disc and fixedly connected with the lifting hook; and an elastic return rope used for driving the rotary disc to roll and unroll the pulling rope is arranged on the electric hoist, a buckle is rotatably connected to the outer edge of the rotary disc, and a fixing hook used for fixing the buckle under the effect of centrifugal force is arranged on the position, located above the rotary disc, of the electric hoist.

Description

technical field [0001] The invention relates to the technical field of drainage treatment, in particular to an electric single-girder bridge crane for a drainage pump room. Background technique [0002] The main components of the drainage pump room are the pump room and the sump, and the pump room is equipped with a unit composed of water pumps and power equipment. The power equipment is usually an electric motor (see figure), with a switchboard. Lifting equipment is provided on the top of the pump room for lifting the unit during installation and maintenance. Set up mechanical or manual garbage grills in the sump to block the thick and easily caught suspended matter to prevent the water pump from being blocked. The sump has a certain water storage volume to facilitate the start of the water pump.

Problems solved by technology

[0003] The entire drainage pump room equipment includes drainage pumps, accessories and other auxiliary equipment. If there is no good lifting operation, it will greatly affect the efficiency of the drainage pump room.

[0004] Although there are currently many types of cranes used in drainage pump rooms, the accumulated wear and tear has brought hidden dangers to safety, followed by safety issues for the workers who operate the cranes. If a safety accident occurs due to the wear and tear of the crane hoist, It will bring about the personal safety of the operating workers and the economic loss of the enterprise.
