Description
Technical field:
The present invention relates to crane fields, relate generally to a kind of bridge crane.
Background technique:
Bridge crane, which is crossbearer, carries out the lifting equipment of material handling in workshop, warehouse and stock ground overhead, due to it
Both ends are located on tall and big concrete column or metallic support, and shape is gained the name like bridge.The cunning of girder two sides in the prior art
It is independent for moving, and thus needs two motors, and root power line has also been needed between girder, more power lines not only influence
Integral layout, and electric wire will increase fault point, the operation simultaneously in time of two motors is also it is difficult to ensure that it is synchronized, and existing skill
The slide at the girder both ends in art mostly does long in order to which anti-row hangs overturning, and one side mobile space is limited, on the other hand
Increase the weight of complete machine；It is the structure of slidingtype in total, positioning performance is poor, to influence the accuracy of parking
Can, the time is longer, and error is bigger, therefore is not able to satisfy the requirement of long-time service, and structure all has much room for improvement.
Summary of the invention:
The object of the invention is to remedy the disadvantages of known techniques, provides a kind of bridge crane, and overall structure is simple
Design rationally, integrates that Synchronous Transmission, stability is good, anti-overturning performance, meets requirement.
The present invention is achieved by the following technical solutions:
A kind of bridge crane includes crane girder, and the middle part guiding of the crane girder is combined with Mobile base,
The both ends of the crane girder are respectively equipped with the slide with track cooperation, it is characterised in that: the outer lower end portion of the slide
Power chain is installed, guide groove corresponding with power chain position is respectively equipped on the track, is laid in the guide groove with teeth
Item, the front and back end of the power chain are separately installed with guide roller, and the medial surface guiding cooperation of the guide roller and guide groove is described
The inner lower edge portion of slide is equipped with L shape guide rod, is equipped with idler wheel on the L shape guide rod horizontal segment, the inside of the track is equipped with
The boss of outwardly convex, wheel face, which rolls, on the boss lower surface and idler wheel cooperates, the slide of the crane girder side it
Between transmission shaft is installed, the both ends of the transmission shaft are separately installed with drive sprocket, the power chain respectively with corresponding end
Drive sprocket transmission engagement, and the power chain of one end is driven by motor.
The power chain is mounted on the bottom face in the middle part of slide by fixed frame, and the fixed frame includes welding
Fixed plate in slide bottom end is rotatably equipped with shaft in the middle part of the fixed plate, power chain is equipped in the shaft, and
The shaft of one side is driven by motor.
The bottom face of the guide roller is located at the lower section of guide groove oral area and the top of rack gear.
The inner lower edge portion of the slide is equipped at least two L shape guide rods, and the upper end of the vertical section of its L shape guide rod
It is fixed on slide medial surface bottom end, the end of horizontal segment is equipped with directive wheel by bearing.
The middle part of the transmission shaft is by multiple bearing supports, and bearing is mounted on crane girder by bearing block
Side, and it is covered with shell.
Its working principle is that: by the way that the transmission chain structure engaged with track guide groove inner rack is arranged in the bottom end of slide, from
And keeping parking more quasi- more steady, by same motor driven, transmission passes through the biography between it for the power chain driving of longitudinal movement
In addition driving-axle gearing reduces the electric wire across girder, facilitates integral layout to ensure that the net synchronization capability of the two, and
The fault point for reducing electric wire generation, under the inside boss by idler wheel and track on the inner lower edge portion L shape guide rod of slide
End face rolls cooperation, and structure is the mechanism of anti-overturning, to guarantee to guarantee that it will not be turned over while shortening two slide length
Vehicle, and the type of complete machine is alleviated, increasing service performance, the front and back of the power front-wheel are also equipped with guide roller, from
And guarantee the stability of slide operation, overall structure simple designs are reasonable, collect Synchronous Transmission, stability is good, anti-overturning performance in
One, meets requirement.
The invention has the advantages that
Structure of the invention design rationally, reduces the electric wire across girder, facilitates integral layout, and reduces electric wire production
Raw fault point, while also guaranteeing the stability of slide operation, integrates that Synchronous Transmission, stability is good, anti-overturning performance, full
Foot requirement.
