Abstract
The utility model relates to a lifting device for an electric wrench of a large wind generating set. The lifting device comprises a base and a lifting rod, wherein the base is provided with a support leg frame, the lifting rod is connected on the support leg frame through a pin shaft, an electric wrench lifting disk is arranged at the front end of the lifting rod, the lifting disk comprises a disk body connected with the lifting rod, and a plurality of stopping blocks are arranged on the disk body. The electric wrench can be arranged on the lifting disk so as to eliminate manual fixing. Simultaneously, the lever principle is used, and the electric wrench can be moved easily when the lifting rod is lifted and pressed. The lifting device is reasonable in structure and convenient to use, substitutes manual adjustment, eliminates safety hazards in assembling, can conveniently and quickly adjust the position of the electric wrench, greatly reduces labor burden, and improves assembling work efficiency, especially efficiency of fastening bolts in narrow space.
Description
Technical field
The utility model relate to a kind of device of lifting, particularly a kind of Large-scale Wind Turbines power-operated wrench lift device.
Background technology
Along with the progress of wind generating technology, practice thrift the main direction that cost becomes research, the single-machine capacity that increases wind power generating set can reduce the input expense and the project cost of development of Infrastructure; And same generating capacity needs the unit of lesser number, also practiced thrift the average unit cost of manufacturing cost and operating maintenance greatly.The development tendency that is inevitable so wind power generating set maximizes.
But the increase of wind power generating set single-machine capacity; Must cause the corresponding expansion of element size; Produce for complete machine, the assembly difficulty of parts also increases accordingly, and power-operated wrench is a kind of common tool in the wind power generating set assembling; For Large-scale Wind Turbines, common heaviness of the power-operated wrench of use and comparison of sizes are big.Conventional electric-powered spanner method of application is to lift power-operated wrench with manpower, regulates the power-operated wrench position, fitting-up bolt is carried out fastening, and in the small space difficult installation, and working strength is bigger, very influences work efficiency.
Summary of the invention
The utility model technical matters to be solved is the deficiency to prior art, provide a kind of Large-scale Wind Turbines simple in structure, easy to use power-operated wrench lift device.
The utility model technical matters to be solved is to realize through following technical scheme; The utility model be a kind of Large-scale Wind Turbines power-operated wrench lift device, be characterized in: it comprises base and lifts bar that base is provided with supporting rack; The described bar of lifting is connected on the supporting rack through bearing pin; The front end of lifting bar is provided with power-operated wrench and lifts dish, and the described dish of lifting comprises and lift bar bonded assembly disk body that disk body is provided with several blocks.
The utility model technical matters to be solved can also realize that further described block evenly is located at disc perimeter through following technical scheme.
The utility model technical matters to be solved can also realize that further described block is the column block through following technical scheme.
The utility model is lifted on the dish through power-operated wrench is placed on, and has save manpower and has fixed, and utilizes lever principle simultaneously, carries and presses down on carrying out and just can accomplish moving of power-operated wrench easily lifting bar; Compared with prior art, it is rational in infrastructure, and is easy to use; Replace manual shift, the potential safety hazard when having eliminated assembling can conveniently be regulated the power-operated wrench position; Alleviated the manpower burden greatly, improved fitting work efficient, especially the efficient when the small space binding bolt.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Following with reference to accompanying drawing, further describe the concrete technical scheme of the utility model, so that those skilled in the art understands the utility model further, and do not constitute restriction to its right.
