Description

A kind of pair of reductor lifting mechanism crane in bridge type

(1) technical field

The utility model relates to the elevator machinery field, is specifically related to a kind of crane in bridge type that sets the handling large-sized object of two group reductor lifting mechanisms.

(2) background technology

Along with improving constantly of China's industrial equipment level; The large bridge crane tool is used in places such as railway, factory, mine, harbour, warehouse, shop in a large number; Special equipment as the handling large-sized object; Adopt the crane in bridge type of reductor lifting mechanism; Advances such as its safe, reliable, efficient rate are also more and more by extensive concern, and also there is very big gap in the relative international advanced technology of the hoisting crane of China industry, and the innovation of Chinese hoisting crane industry has become the very important link of national industry development.Reductor lifting mechanism crane in bridge type as the handling large-sized object; Be applicable to large-sized object loading and unloading and lifting transport in the logistics transportation; Its corresponding structure fastness and mode all need the failure-free design, and the utility model has mainly carried out corresponding innovation to the type weight-lifting equipment in Optimal Structure Designing and mode design.

(3) summary of the invention

The utility model mainly provide a kind of complete machine structure reasonable in design, control easily two reductor lifting mechanism crane in bridge type, main technical schemes is following:

A kind of pair of reductor lifting mechanism crane in bridge type mainly comprises girder, end carriage, lifting mechanism and control cabin, and said girder designs for twin beams; Two parallel settings of girder, on the end carriage of two sides, girder and end carriage adopted the buckle type to be hinged about two ends of girder were separately fixed at; And connect with high strength bolt; Each side beam is equipped with one group of wheel, and the traveling gear that adopts retarder and frequency conversion braking motor to combine, and has realized connecting with the flexibility of end carriage; Efficiently solving traditional retarder connects with walking on stage because of base that retarder, motor and drg are installed; Be prone to produce the problems such as traveling gear displacement that cause because of the vibration-sunk of walking on stage, also alleviated the weight of walking on stage simultaneously, practiced thrift the manufacturing cost of equipment.

Described lifting mechanism is provided with two groups; Be placed on two girders through set of wheels by framing member respectively; Framing member is provided with movable motor; Lifting mechanism is the set-up mode that retarder and frequency conversion braking motor combine, and can adopt the handling mode that two groups hoist or single group hoists according to the weight of handling object.

Said girder is provided with control cabin near the below of end carriage one side, and control cabin is connected with a simple and easy ladder with girder, and operating personal can pass in and out control cabin through simple and easy ladder from girder.

The major advantage of the utility model is that girder and crossbeam adopt the buckle type to be hinged, and with the two Bolt Connection of high strength, has improved the integral structure fastness of elevator machinery; Lifting mechanism is set to two groups, is the set-up mode that retarder and frequency conversion braking motor combine, and can adopt the handling mode that two groups hoist or single group hoists according to the weight of handling object; All machinery all can be handled in operator's compartment by the fixing operation personnel, in the long working process, can alleviate the personnel's of controlling labour intensity.
