Abstract
A crane cylinder tower body pre-installing basic tool comprises foundation padding, embedded parts and a tower body basic part. The tower body basic part comprises cylinder bodies and connecting flanges, the upper planes of the embedded parts are in a same plane, the cylinder bodies are fixed on the foundation padding through the embedded parts, and the connecting flanges are fixed on the cylinder bodies and of an inverted T-shaped structure. The crane cylinder tower body pre-installing basic tool has the advantages that in the improving process for manufacturing a tower body, the machining difficulties are reduced, operation for repairing structural distortion is reduced, production efficiency is improved, quality of products is further improved, cost is lowered, and the crane cylinder tower body pre-installing basic tool is good in effect, economical and practical.
Description
Technical field
This utility model relates to a kind of mounting tool of crane body of the tower, and particularly a kind of crane cylinder body of the tower is pre-installed basic frock, belongs to crane manufacturing technology field.
Background technology
Cylindrical tower is as the crane common structure, because the limitation that machining equipment exists, and large-scale steel structure inevitable welding deformation in manufacture process, cause at last the very difficult flatness that guarantees large flange junction.The requirement that does not reach flatness will bring on the application life of product very large impact.
To the problems referred to above, way commonly used is exactly to increase packing ring at two flange connections to level up at present, but because physical dimension, the operating frequency of crane and the impact of pad material of body of the tower, this method just seems and cures the symptoms, not the disease, need often equipment to be overhauled, do like this and not only lose time but also wasted cost, also can bring certain impact to routine work.
Summary of the invention
Goal of the invention: the purpose of this utility model provides a kind of crane cylinder body of the tower that can reduce the quality of fit of cylinder body of the tower manufacture difficulty, the connection of raising flange and pre-installs basic frock.
Technical scheme: a kind of crane cylinder body of the tower is pre-installed basic frock, comprises ground based filler, built-in fitting and body of the tower basic part; Described body of the tower basic part comprises cylinder body and adpting flange, the upper plane of described built-in fitting at grade, described cylinder body is fixed on the ground based filler by built-in fitting, and described adpting flange is fixed on the cylinder body, and described adpting flange is the convex shape structure.At last process equipment is hung on and just can utilize unit head to carry out the processing on plane after just going for, can guarantee like this machining accuracy of flange, make the prepackage of body of the tower be connected connection with bolt hole and can reach very high precision.Greatly reduce workload and difficulty, the easier guarantee of quality.
In order to protect the reliability on body of the tower basis; have at least the ground based filler of three groups of band built-in fittings to be distributed on the circumference of cylinder body; be evenly equipped with the body of the tower bracing frame that quantity equates with ground based filler quantity on the outside diameter wall of described body of the tower basic part, described body of the tower bracing frame is fixedly connected with between two ground based fillers and with body of the tower basic part external diameter.
Preference is on the angular bisector that is centered close to angle between two ground based fillers of described body of the tower bracing frame.
For body of the tower after protecting installation does not sink, described ground based filler comprises the rubble filler of bottom and the concrete fill on top.
Beneficial effect: the utility model has reduced mechanical processing difficulty in improving the body of the tower manufacture process, reduced the repair of malformation, has improved production efficiency, and product quality also further improves, and has reduced simultaneously cost, and is effective, economical and practical.
Description of drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of crane cylinder body of the tower is pre-installed basic frock, comprises ground based filler 1, built-in fitting 2 and body of the tower basic part 3; Described body of the tower basic part 3 comprises cylinder body 4 and adpting flange 5, the upper plane of described built-in fitting 2 at grade, described cylinder body 4 is fixed on the ground based filler 1 by built-in fitting 2, and described adpting flange 5 is fixed on the cylinder body 4, and described adpting flange 5 is the convex shape structure.Described ground based filler 1 comprises the rubble filler 7 of bottom and the concrete fill 8 on top.
As shown in Figure 2, the ground based filler 1 that ground is provided with four groups of band built-in fittings 2 is distributed on the circumference of cylinder body 4, be evenly equipped with the body of the tower bracing frame 6 that quantity equates with ground based filler 1 quantity on the outside diameter wall of described body of the tower basic part 3, described body of the tower bracing frame 6 is fixedly connected with between two ground based fillers 1 and with body of the tower basic part 3 external diameters.On the angular bisector that is centered close to angle between two ground based fillers 1 of described body of the tower bracing frame 6.
