Abstract
The utility model provides a kind of for the support platform in fan blade bolt extraction device, one lateral edges of flat surface is to extending to form the first protruding end and the second protruding end outside it, offer fixing hole a and fixing hole b respectively at the first protruding end and the second protruding end, the edge between the first protruding end with the second protruding end is the inner concavity camber line identical with blade edge shape.The blade of blower fan can dock with platform by the utility model, can reduce the gap between extraction device and fan blade, and the operating side of extraction device is fully contacted with bolt; The contact area between blade and platform can be increased by the protruding end of two in support platform; Because two fixing holes are arranged on the front end of platform, therefore, flat surface in the course of the work steady can be ensured.
Description
Technical field
The utility model relates to a kind of platform, especially a kind of for the support platform in fan blade bolt extraction device.
Background technology
At present, before carrying out taking-up operation to the bolt in fan blade, need extraction device to be placed in a support platform.But, existing support platform is generally the surface plate that operating personnel arbitrarily find at the construction field (site), because the shape of this surface plate and the edge of fan blade do not meet, therefore, make between extraction device and blade, to there is very large gap, the operating side of extraction device cannot be made fully to contact with bolt.
Summary of the invention
For the weak point existed in the problems referred to above, the utility model provides a kind of gap of reducing between support platform and blade, the operating side of extraction device and bolt are fully contacted for the support platform in fan blade bolt extraction device.
For achieving the above object, the utility model provides a kind of for the support platform in fan blade bolt extraction device, one lateral edges of flat surface (1) is to extending to form the first protruding end (2) and the second protruding end (3) outside it, offer fixing hole a (4) and fixing hole b (5) respectively described first protruding end (2) and described second protruding end (3), the edge between described first protruding end (2) with described second protruding end (3) is the inner concavity camber line (6) identical with blade edge shape.
Above-mentioned for the support platform in fan blade bolt extraction device, wherein, the rear side of described inner concavity camber line (6) is formed with the region for placing magnetic drill press.
Above-mentioned for the support platform in fan blade bolt extraction device, wherein, all end angles of platform are fillet structure.
Compared with prior art, the utility model has the following advantages:
The blade of blower fan can dock with platform by the utility model, can reduce the gap between extraction device and fan blade, and the operating side of extraction device is fully contacted with bolt;
The contact area between blade and platform can be increased by the protruding end of two in support platform;
Because two fixing holes are arranged on the front end of platform, therefore, flat surface in the course of the work steady can be ensured.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Main Reference Numerals is described as follows:
1-flat surface 2-first protruding end 3-second protruding end
4-fixing hole a 5-fixing hole b 6-inner concavity camber line
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of for the support platform in fan blade bolt extraction device, and wherein, all end angles of platform are fillet structure.
One lateral edges of flat surface 1 is to extending to form the first protruding end 2 and the second protruding end 3 outside it.Offer respectively for being fixed fixing hole a4 also and fixing hole b5 to flat surface at the first protruding end 2 and the second protruding end 3, the edge between the first protruding end 2 with the second protruding end 3 is the inner concavity camber line 6 identical with blade edge shape.The rear side of inner concavity camber line 6 is formed with the region for placing magnetic drill press.
Because magnetic drill press is placed on the position near inner concavity camber line, therefore, fixing hole a and fixing hole b is separately positioned on the position of the first protruding end 2 and the second protruding end 3, flat surface in the course of the work steady can be ensured.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
Claims (3)
