Abstract
The utility model discloses a connection structure of main and assistant crane cars, and aims to design the connection structure of the main and assistant crane cars, which has a reasonable structure and can effectively improve the production efficiency of crane cars. The utility model adopts the technical scheme that the connection structure of the main and assistant crane cars comprises a car body and a lug plate, wherein a strip-shaped hole is processed in the lug plate on the car body. The connection structure of the main and assistant crane cars has the advantages of simple structure, convenience in use and convenience and quickness for installation and can effectively improve the production efficiency of the crane cars.
Description
Technical field:
The utility model relates to weight-lifting equipment, particularly a kind of hoisting crane major-minor dolly connection structure that is applicable to the hoisting crane use.
Background technology:
Present hoisting crane, especially in indoor use, limit for height there is more requirement, satisfying under the prerequisite that hoisting crane uses, how the equipment on the hoisting crane being reduced highly is comparatively common thinking, is a common thinking with the major-minor dolly with the dolly height reduction of hoisting crane, but the major-minor dolly links by connection and connects, it is higher to the connection holes requirement on machining accuracy on the otic placode to add man-hour, could satisfy the connection needs of major-minor dolly, brings more inconvenience for processing and production.
Summary of the invention:
The purpose of this utility model is that design is a kind of rational in infrastructure, hoisting crane major-minor dolly connection structure that can Effective Raise monkey production efficiency.
The technical solution of the utility model is, a kind of hoisting crane major-minor dolly connection structure, and it comprises car body, otic placode is characterized in that: the otic placode on the car body is processed with the strip shape hole.
The utility model is simple in structure, and is easy to use, can improve monkey production efficiency by actv., and it is convenient to install.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail, structure of the present utility model is, a kind of hoisting crane major-minor dolly connection structure, and it comprises car body 3, otic placode 2, the otic placode on the car body is processed with strip shape hole 1.On the main car body or the otic placode on the secondary car body select one and open and be the strip shape hole, be convenient to another car body on lug plate holes corresponding, it is comparatively convenient to install, the while difficulty of processing is lower, production efficiency is higher.The utility model can actv. improves the production efficiency of hoisting crane, has reduced the difficulty of equipment processing.
