Abstract
A kind of telescopic crane boom belongs to telescopic crane boom.The inner arm oil cylinder is positioned at the top on basic arm surface, and inner arm oil cylinder one end is fixed on the basic arm of telescopic boom, and the other end is fixed on the inner arm of telescopic boom.Oil cylinder places the telescopic boom upper surface, oil cylinder one end is fixed on the telescopic boom basic arm, the other end is fixed on the telescopic boom inner arm, flexible inner arm oil cylinder, just make the arm body generation slide relative of the basic arm and the inner arm of telescopic boom, because telescopic oil cylinder is the basic arm outside that is placed on telescopic boom, i.e. the external mounting means of inner arm oil cylinder is convenient to dismounting and maintenance, is easy to find fault such as inner arm oil cylinder leakage of oil.The advantage that oil cylinder is external, the inner arm oil cylinder is easy to Assembly ﹠Disassembly, has improved work efficiency; Phenomenons such as leakage of oil appear in the inner arm oil cylinder, can in time find also to be convenient to maintenance; Do not need to consider the installing space of inner arm oil cylinder during installation, make easier for installationly that therefore, its field of application is more extensive.
Description
Technical field
The utility model relates to a kind of telescopic crane boom.
Background technology
At present, the telescopic boom of hoisting crane be by basic arm, inner arm and the inner arm oil cylinder constitute, inner arm is installed in the basic arm, inner arm is the blank pipe shape, the inner arm oil cylinder is installed in the inner arm blank pipe, inner arm oil cylinder one end is connected the other end and is connected with the end of inner arm with basic arm.It is that the inner arm oil cylinder is built-in that this inner arm oil cylinder is installed in telescopic boom in-to-in mode, and the built-in mounting means of this inner arm oil cylinder is not easy to dismounting and maintenance, in case faults such as inner arm oil cylinder generation leakage of oil are not easy timely discovery; Also must have enough installing spaces in the blank pipe of inner arm when the inner arm oil cylinder is installed, otherwise can't install.
Summary of the invention
The purpose of this utility model is that a kind of telescopic crane boom of being convenient to dismounting and maintenance, being easy to find inner arm oil cylinder oil leakage fault will be provided.
The purpose of this utility model is achieved in that the inner arm oil cylinder is positioned at the top on basic arm surface, and inner arm oil cylinder one end is fixed on the basic arm of telescopic boom, and the other end is fixed on the inner arm of telescopic boom.
Beneficial effect: owing to adopt such scheme, oil cylinder places the telescopic boom upper surface, oil cylinder one end is fixed on the telescopic boom basic arm, the other end is fixed on the telescopic boom inner arm, and flexible inner arm oil cylinder just makes the arm body generation slide relative of the basic arm and the inner arm of telescopic boom, because telescopic oil cylinder is the basic arm outside that is placed on telescopic boom, be the external mounting means of inner arm oil cylinder, be convenient to dismounting and maintenance, be easy to find faults such as inner arm oil cylinder leakage of oil, reached the purpose of this utility model.The advantage that oil cylinder is external, the inner arm oil cylinder is easy to Assembly ﹠Disassembly, has improved work efficiency; Phenomenons such as leakage of oil appear in the inner arm oil cylinder, can in time find also to be convenient to maintenance; Do not need to consider the installing space of inner arm oil cylinder during installation, make easier for installationly that therefore, its field of application is more extensive.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
