Description
Technical field
The utility model relates to hoisting crane, particularly relates to a kind of overhead crane with electric hoists.
Background technology
Along with the develop rapidly of economic construction, construction machinery and equipment obtains in fields such as building, mineral products and generally applies, and hoisting crane has become the requisite lifting appliances in field such as shipping, building, mineral products as a kind of important construction machinery and equipment.
Existing overhead crane with electric hoists generally comprises girder, the end carriage at support girder two ends, electrical equipment and electric block, electric block comprises suspension hook, lifting motor and dolly, girder and end carriage pass through Bolt Connection, but the following problem of ubiquity: is the rail of dolly on girder slides be commonly the poor point contact type of sliding effect, area of contact is little and add Wheel Fatigue loss, reduces the service life of wheel; Two is that girder and end beam device compensate for the problem of Joint strenght deficiency to a certain extent by Bolt Connection, but lack link and antifriction device between girder and end carriage, because car wheel is in girder side, inclined abrasive power is produced in walking process, electric block is made to occur the situation of vertical divergence or lateral deviation, cause hoisting crane span and gauge mismate to cause card rail, gnaw the faults such as rail, thus cause hoisting crane work surely uneven and occur that deviation even has an accident.
Summary of the invention
The utility model exists the rail of dolly on girder slide for overhead crane with electric hoists in prior art and is commonly the poor point contact type of sliding effect, lacks the shortcoming of link and antifriction device between girder and end carriage, provide a kind of car wheel and rail be line contact type, overhead crane with electric hoists with link and antifriction device between girder and end carriage.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of overhead crane with electric hoists, comprise two end carriages, be located at girder between two end carriages, electrical equipment and the electric block that electrically connects with electrical equipment, electrical equipment and electric block are all located on girder, electric block comprises dolly, dolly is located at above girder, girder is provided with the square steel rail be welded into one with girder, and dolly slides along square steel rail; Be provided with connecting panel between girder and end carriage, connecting panel is provided with the annular arrangement polyurethane bumper absorber for bearing friction force.
As preferably, also comprise the bogie type cart be connected with girder and end carriage, bogie type cart comprises eight groups of adustable wheel groups, and bogie type cart is provided with operator's compartment.
As preferably, lifting velocity and the lifting altitude of electric block are respectively 4m/min and 12m, and electric block also comprises suspension hook and lifting motor, and suspension hook is connected with dolly, and lifting motor and electrical equipment electrically connect.
As preferably, girder is made up of Q345B steel, and girder, connecting panel, end carriage are fastening by high strength bolt, girder is fixed with People's Bank of China's guardrail, is connected with cat ladder below girder.
The utility model is owing to have employed above technical scheme, there is significant technique effect: adopt Q345B steel plate type square steel rail and square steel rail and girder to be welded into one, by arranging connecting panel and annular arrangement polyurethane bumper absorber between girder and end carriage, greatly reducing hoisting crane work injustice and surely occurring the possibility that deviation even has an accident.
