Abstract
The invention relates to a double-beam bridge type crane comprising a cart operating mechanism, a trolley and a crane span structure. In addition, the double-beam bridge type crane is characterized in that: the cart operating mechanism employs a two-angle driving mode and each angle is used to drive a wheel group; the wheels employ double wheel flanges; a three-in-one reducer motor whose insulation level is an F level is utilized and a walking board is arranged; and polyurethane buffers are arranged at four corners of the crane. The trolley adopts a three-in-one centralized driving unit, which includes a wheel group, a three-in-one reducer motor with an F insulation level, a transmission shaft and a coupler. And the crane span structure is formed by a main girder, rails, an end beam, and auxiliary equipment that are needed for repairing work and includes a walking board and a ladder, wherein the main girder employs a bias-rail box girder. Moreover, electric conduction of the trolley is realized by dragging a flexible cable by a pulley for power supply.
Description
Technical field
The present invention relates to mechanical manufacturing field, relate to a kind of twin beam overhead bridge crane specifically.
Background technology
Hoisting crane generally can be divided into small-sized weight-lifting equipment, bridge type crane tool and jib type hoisting crane three major types: crane in bridge type (claiming overhead traveling crane again) is a kind of crane span structure type hoisting crane that crane span structure moves on aerial conveyor; The crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead; Crane carriage laterally moves along the track that is laid on the crane span structure, constitutes the operating range of a rectangle.
Ordinary bridge crane generally is made up of crane carriage, crane span structure operating unit, crane span structure metal construction.Crane carriage comprises lifting mechanism, wheeling mechanism and trolley frame three parts composition.
Lifting mechanism comprises electrical motor, drg, retarder, reel and assembly pulley; Electrical motor drives reel and rotates through retarder, steel rope is put down, with the up-down weight around coiling or from reel; Trolley frame is rest and the frame that parts such as lifting mechanism and wheeling mechanism are installed, and is generally welded structure.
Crane in bridge type can be divided into three kinds in ordinary bridge crane, simple and easy beam bridge formula hoisting crane and metallurgical special-purpose crane in bridge type.
Crane in bridge type be a kind of crossbearer in the workshop, warehouse and the sky, the stock ground weight-lifting equipment that carries out the material handling; Because the crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead; Can make full use of the space handling material below the crane span structure; Do not receive the obstruction of wayside equipment, so it is to use a kind of lifting equipment widest in area, that quantity is maximum.Oad is big, wheel load is higher but existing common crane in bridge type exists mostly, is inappropriate for shortcomings such as place such as being applied to general mechanical department, warehouse, stock ground.
Summary of the invention
In view of the defective that prior art exists, the objective of the invention is to provide a kind of simple to operate, safe reliability is excellent, wheel load is less twin beam overhead bridge crane.
The technical scheme that the present invention adopted is:
A kind of twin beam overhead bridge crane; Comprise traveling mechanism of the larger traveller, dolly and crane span structure; It is characterized in that: said traveling mechanism of the larger traveller adopts two jiaos of drivings, and every angle drives a set of wheels, and wheel adopts the two-wheel edge; The F level) and be provided with and walk on stage (class of insulation:, hoisting crane respectively is provided with a polyurethane bumper absorber for four jiaos to adopt three-in-one reductor electrical motor.Said dolly adopts three-in-one centralized driving, comprising: set of wheels, three-in-one reductor the electrical motor, (class of insulation: the F level) transmission shaft and coupler composition; Said crane span structure by girder, track, end carriage and service work required walk on stage, accessory equipment such as ladder constitutes, girder adopts inclined to one side rail box beam; Said dolly conduction form is that coaster drags the flexible cable power supply.
Said girder and end carriage adopt the bolt fastening structure form, and girder adopts two girders.
Said set of wheels adopts tilting bearing, and wheel adopts two-wheel edge, wheel material ZG50SiMn.
After adopting such scheme, compare the present invention with existing product and have the following advantages:
The present invention is from heavy and light, little, simple in structure, the installation and maintenance convenience of volume, and man-machine harmony property is good; Adopt two inclined to one side rail box beam of girder, high efficiency, the complete machine weather resisting property is strong, is particularly useful for the general lift heavy handling labor that carry out in the places such as maintenance assembling in machine manufacture workshop, warehouse, stock ground, power station.
